Risk factors for one-year mortality in 440 femoral peri-implant fractures: insights from the PIPPAS prospective, multicentre, observational study.

Aims: The Peri-Implant and PeriProsthetic Survival AnalysiS (PIPPAS) study aimed to investigate the risk factors for one-year mortality of femoral peri-implant fractures (FPIFs).

Methods: This prospective, multicentre, observational study involved 440 FPIF patients with a minimum one-year follow-up. Data on demographics, clinical features, fracture characteristics, management, and mortality rates were collected and analyzed using both univariate and multivariate analyses.

Impact of radiological follow-up frequency on resected lung cancer: a propensity score matching analysis.

Background: Despite advances in lung cancer treatment and the subsequent improvement in oncological outcomes, the optimal frequency of radiological follow-up remains unclear. Current recommendations lack consensus and do not consider individual patient characteristics and tumor factors. This study aimed to examine the impact of radiological follow-up frequency on oncological outcomes following lung cancer resection.

Long Term Follow-Up Observation in Small Choroidal Melanocytic Tumors.

Background: The purpose of this study is to analyze the long-term evolution of patients with small choroidal melanocytic tumors (SCMTs) undergoing observation, and to assess their rate of transformation into melanomas and survival.

Methods: A retrospective single-cohort study of patients with SCMTs (1-3 mm in height and 5-10 mm in base) diagnosed from January 1992 to February 2023 was carried out, with observation as the initial treatment. The main criterion for a transformation into melanoma is considered to be an increase in size of more than 1 mm in height and/or more than 1 mm in base measured on an ultrasound/retinography, recorded in two consecutive visits separated by one to three months.

Clinic-pathological agreement in the diagnosis of conjunctival tumours: Analysis of 195 cases.

Purpose: The present study aims to assess the agreement between clinical and pathological diagnosis in conjunctival tumours in a specialist ocular oncology unit.

Methods: retrospective study of consecutive patients with conjunctival tumours diagnosed at the Ocular Oncology Unit of the University Hospital of Valladolid was performed from 1992 to 2017. Tumours were classified according to their origin (epithelial, melanocytic, lymphoid and others) and degree of malignancy (benign, premalignant, malignant).
