Neoadjuvant therapy versus upfront surgery in resectable pancreatic cancer: reconstructed patient-level meta-analysis of randomized clinical trials.

Background: Neoadjuvant treatment has shown promising results in patients with borderline resectable pancreatic ductal adenocarcinoma. The potential benefits of neoadjuvant treatment on long-term overall survival in patients with resectable pancreatic ductal adenocarcinoma have not yet been established. The aim of this study was to compare long-term overall survival of patients with resectable pancreatic ductal adenocarcinoma based on whether they received neoadjuvant treatment or underwent upfront surgery.

Modern cementless acetabular cups in total hip arthroplasty performed for primary osteoarthritis: a comparative registry study.

Introduction: Comparative studies evaluating the different material and surface finishing of acetabular components in total hip arthroplasty (THA) are lacking. Using a regional arthroplasty registry, the survival rates and the hazard ratios of different cups in THA performed for primary osteoarthritis were assessed, using endpoints: (1) every cup failure, (2) cup aseptic loosening, (3) periprosthetic infection.

Materials And Methods: The inclusion criteria were: residing patients, THA for primary osteoarthritis, Delta-on-Delta bearings, head sizes 32 mm and 36 mm.

Temporal Relationship Between Pain and Mental Health Conditions Among Children and Young People-A Population-Based Register Study in Sweden.

Both pain and mental health conditions are common among young people. They often co-occur, but we wanted to investigate further whether it is pain (abdominal pain, headache, musculoskeletal pain, menstrual pain) that precedes mental health conditions (depression, anxiety, stress, phobia) or whether it is the other way around, mental health conditions that precede pain. Using electronic health records-the Skåne Healthcare Register-we identified and followed young people aged 7 to 18 over a 13-year period and tracked all their registered diagnoses.

Patritumab deruxtecan in HER2-negative breast cancer: part B results of the window-of-opportunity SOLTI-1805 TOT-HER3 trial and biological determinants of early response.

Patritumab deruxtecan (HER3-DXd) exhibits promising efficacy in breast cancer, with its activity not directly correlated to baseline ERBB3/HER3 levels. This research investigates the genetic factors affecting HER3-DXd's response in women with early-stage hormone receptor-positive and HER2-negative (HR+/HER2-) breast cancer. In the SOLTI-1805 TOT-HER3 trial, a single HER3-DXd dose was administered to 98 patients across two parts: 78 patients received 6.

Purpose: The purpose of this study was to investigate if patient's gender significantly affected the long-term outcome of patients undergoing total knee arthroplasty (TKA) and to provide a cross-gender comparison of a large patient sample from a single regional register.

Methods: The Registry of Prosthetic Orthopedic Implant of Emilia Romagna (RIPO) investigated all primary TKAs performed from July 2000 to December 2020 by collecting data of men and women separately. Primary bicompartmental and tricompartmental TKAs were included.

Features and behaviours for weight loss in the Chilean cohort with obesity from the ACTION study.

In Latin America, obesity rates are among the highest in the world. Currently, people with obesity (PWO) receive suboptimal care due to several challenges and barriers. The international ACTION-IO study aimed to identify perceptions, attitudes and behaviours of PWO and healthcare providers (HCP), and to assess potential barriers to effective obesity care.

New insights into the regulation of bile acids synthesis during the early stages of liver regeneration: A human and experimental study.

Background And Aims: Liver regeneration is essential for the preservation of homeostasis and survival. Bile acids (BAs)-mediated signaling is necessary for liver regeneration, but BAs levels need to be carefully controlled to avoid hepatotoxicity. We studied the early response of the BAs-fibroblast growth factor 19 (FGF19) axis in healthy individuals undergoing hepatectomy for living donor liver transplant.

Short- and long-term outcomes after distal pancreatectomy with radiologic infiltration of splenic vessels for pancreatic ductal adenocarcinoma.

Background: The effect of radiologic splenic vessels involvement (RSVI) on the survival of patients with pancreatic adenocarcinoma (PAC) located in the body and tail of the pancreas is controversial, and its influence on postoperative morbidity after distal pancreatectomy (DP) is unknown. This study aimed to determine the influence of RSVI on postoperative complications, overall survival (OS), and disease-free survival (DFS) in patients undergoing DP for PAC.

Methods: A multicenter retrospective study of DP was conducted at 7 hepatopancreatobiliary units between January 2008 and December 2018.

Analytical validation of HER2DX genomic test for early-stage HER2-positive breast cancer.

Background: HER2DX, a multianalyte genomic test, has been clinically validated to predict breast cancer recurrence risk (relapse risk score), the probability of achieving pathological complete response post-neoadjuvant therapy (pCR likelihood score), and individual ERBB2 messenger RNA (mRNA) expression levels in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer. This study delves into the comprehensive analysis of HER2DX's analytical performance.

Materials And Methods: Precision and reproducibility of HER2DX risk, pCR, and ERBB2 mRNA scores were assessed within and between laboratories using formalin-fixed paraffin-embedded (FFPE) tumor tissues and purified RNA.

Cementless Primary Stems in Revision Hip Arthroplasty: A Narrative Review.

Cementless primary stems in revision hip arthroplasties may be conservative options to preserve bone stock and provide adequate reconstruction of the hip biomechanics. However, there is still little evidence about indications, limitations, and outcomes. This narrative review showed that conventional standard stems were adopted in different revision settings, up to Paprosky IIIA grade bone defects.

Chronological Changes in Sagittal Femoral Bowing after Primary Cementless Total Hip Arthroplasty: A Comparative 3D CT Study.

Little is known about dynamic changes of femoral anatomy after total hip arthroplasty (THA), in particular about sagittal femoral bowing (SFB). A 3D CT study was designed to evaluate the chronological changes of SFB after cementless femoral stem implantation for primary THA. Ten patients who underwent unilateral primary THA with a cementless femoral stem, with 2 consecutive CT scans (extending from the fourth lumbar vertebra to the tibial plateaus), performed before THA and at least 3 years after THA, were enrolled.

Textbook outcome in distal pancreatectomy: A multicenter study.

Background: Textbook outcome is an interesting quality metrics tool. Information on textbook outcomes in distal pancreatectomy is very scarce. In this study we determined textbook outcome in a distal pancreatectomy multicenter database and propose a specific definition of textbook outcome-distal pancreatectomy that includes pancreatic fistula.

Total Hip Arthroplasty for Low-Grade Developmental Hip Dysplasia Changes the Ipsilateral Knee Alignment on the Axial and Coronal Planes.

Background: There is a paucity of data regarding the post-operative influence of total hip arthroplasty (THA) on the axial and coronal alignments of the ipsilateral knee. A CT study was designed to assess the post-THA changes in axial and coronal knee alignments in low-grade dysplastic hips.

Methods: Forty Crowe I-II dysplastic hips in 37 patients were assessed: a pre-operative CT scan from the fourth lumbar vertebra to the tibial plateaus was compared to a similar post-operative CT scan performed after a minimum of 2 years after THA.

The placenta is an intriguing organ that allows us to survive intrauterine life. This essential organ connects both mother and fetus and plays a crucial role in maternal and fetal well-being. This chapter presents an overview of the morphological and functional aspects of human placental development.

Higher failure rate of secondary patellar resurfacing following bicompartmental knee arthroplasty.

Introduction: The role of secondary patellar resurfacing (SPR) in anterior knee pain (AKP) is still debated in literature. A regional arthroplasty registry was investigated, aiming to: (1) assess the survival rate of SPR; and (2) compare SPR to tricompartmental TKA.

Materials And Methods: The regional arthroplasty registry RIPO was investigated about all SPRs performed after bicompartmental arthroplasty.

Mapping early serum proteome signatures of liver regeneration in living donor liver transplant cases.

The liver is the only solid organ capable of regenerating itself to regain 100% of its mass and function after liver injury and/or partial hepatectomy (PH). This exceptional property represents a therapeutic opportunity for severe liver disease patients. However, liver regeneration (LR) might fail due to poorly understood causes.

Therapeutic drug monitoring of neoadjuvant mFOLFIRINOX in resected pancreatic ductal adenocarcinoma.

Background: Despite a potentially curative treatment, the prognosis after upfront surgery and adjuvant chemotherapy for patients with resectable pancreatic ductal adenocarcinoma (PDAC) is poor. Modified FOLFIRINOX (mFOLFIRINOX) is a cornerstone in the systemic treatment of PDAC, including the neoadjuvant setting. Pharmacokinetic-guided (PKG) dosing has demonstrated beneficial effects in other tumors, but scarce data is available in pancreatic cancer.

Unlabelled: Radioembolization (RE) may help local control and achieve tumor reduction while hypertrophies healthy liver and provides a test of time. For liver transplant (LT) candidates, it may attain downstaging for initially non-candidates and bridging during the waitlist.

Methods: Patients diagnosed with HCC and ICC treated by RE with further liver resection (LR) or LT between 2005-2020 were included.

A Modular Head-Neck Adapter System and Ceramic Heads in Revision Hip Arthroplasty: A Registry Study on 354 Implants.

Background: Five- to 10-year outcomes of a modular head-neck adapter system with ceramic heads in revision hip arthroplasty on large populations are still lacking. A registry study about modular adapter system with Delta ceramic head in revisions was designed, aiming to assess (1) the survival rates of the device, (2) the reasons for re-revisions of the device, and (3) a comparison to factory assembled titanium sleeve and Delta head cohort in revision hips.

Methods: Using a regional arthroplasty registry, we investigated the modular adapter system with a ceramic head in revision hips.

The dynamics of boron when amending agricultural soil of the Mediterranean basin with biosolids: trials in leaching columns.

There is mainly a lack of boron (B) in soils with low amounts of organic matter and in acidic and sandy soils. This is especially true in irrigated land or humid regions, where leaching can occur. The results from studying the amount of available B will reveal the status of B in the soil of a specific plot of land.

Delays to surgery following chemoradiotherapy lead to poorer oncologic outcomes in patients with localized pancreatic adenocarcinoma.

Background: although neoadjuvant chemoradiotherapy (NCRT) and surgery are accepted as treatments for pancreatic ductal adenocarcinoma (PDAC), some authors have highlighted the risks of delaying surgery. The objective of this study was to analyze the impact of prolonging the time interval between NCRT and surgery (NCRT-TTS) in PDAC.

Methods: patients treated with NCRT and pancreatoduodenectomy (PD) were identified.
