Occupational chemical exposure and health status of wildland firefighters at th...
Teixeira, Tatiana; Almeida, Liliana; Dias, Isabel; Baptista, João Santos; Santos, Joana; Vaz, Mário; Guedes, JoanaWildland firefighting represents a physically and mentally demanding endeavour fraught with various risk factors. The primary aim of this study is to delineate occupational chemical exposure within the firefighting work environment on the firefront and its implications for firefighters’ health status. A systematic literature review was conducted utilising diverse keyword combinations across Scopus, Web of Scien...
In-shoe plantar pressure measurement technologies for the diabetic foot: A syst...
Castro-Martins, Pedro; Marques, Arcelina; Coelho, Luís; Vaz, Mário; Baptista, João SantosIntroduction Loss of cutaneous protective sensation and high plantar pressures increase the risk for diabetic foot patients. Trauma and ulceration are imminent threats, making assessment and monitoring essential. This systematic review aims to identify systems and technologies for measuring in-shoe plantar pressures, focusing on the at-risk diabetic foot population. Methods A systematic search was conducted acr...
Plantar pressure thresholds as a strategy to prevent diabetic foot ulcers: A sy...
Castro-Martins, Pedro; Marques, Arcelina; Coelho, Luís; Vaz, Mário; Costa, José TorresBackground The development of ulcers in the plantar region of the diabetic foot originates mainly from sites subjected to high pressure. The monitoring of these events using maximum allowable pressure thresholds is a fundamental procedure in the prevention of ulceration and its recurrence. Objective The aim of this review was to identify data in the literature that reveal an objective threshold of plantar press...
Conceito de pressão variável para prevenção ativa da ulceração no pé diabético
Castro-Martins, Pedro; Marques, Arcelina; Coelho, Luís; Vaz, Mário(Introdução) O pé diabético é uma designação usada para diversos problemas nos pés causados por complicações da diabetes, como neuropatia e doença vascular periférica, que aumentam o risco de lesão, infeção, ulceração e amputação. A pressão plantar elevada dentro do sapato é um fator de risco para lesões (Schaperetal, 2024). Soluções como palmilhas para monitorizar a pressão plantar e sapatos para aliviar a pre...
Occupational exposure and health of wildland firefighters: protocol for a syste...
Teixeira, Tatiana; Dias, Isabel; Santos, Joana; Vaz, Mário; Baptista, João Santos; Guedes, J. C.The frequency of forest fires has increased in recent years. This phenomenon has led to an increase in the difficulty of fighting them and an increase in the occupational exposure of firefighters. This study aims to carry out a systematic review protocol to obtain information on firefighters' occupational exposure on the fire front. A protocol was carried out following the Preferred Reporting Items for Systemat...

Mechanical and surface properties of a 3D-printed dental resin reinforced with ...
Salgado, Helena; Fialho, Joana; Marques, Marco; Vaz, Mário; Figueiral, Maria Helena; Mesquita, PedroObjectives: Commercial photocurable polymers used in dental additive manufacturing still have mechanical limitations. The incorporation of graphene may provide interesting advantages in this field. This study aimed to evaluate in vitro the effect of adding graphene nanoparticles to a 3D-printed polymethylmethacrylate dental resin in terms of surface roughness, flexural properties, and hardness. Methods: A 3D-pr...
Towards a pneumatic insole concept to offloading plantar pressure in diabetic f...
Castro-Martins, Pedro; Pinto-Coelho, Luis; Vaz, Mário; Marques, ArcelinaDiabetic foot is a serious complication of diabetes that affects millions of people worldwide. It is characterized by poor circulation, nerve damage and high plantar pressure that can lead to the development of foot ulcers and amputations. Offloading plantar pressure in certain regions is extremely important. In this paper we propose a preliminary methodology for a new concept of a pneumatic insole to offloadin...
Towards an in-shoe pneumatic insole to plantar injury prevention in diabetic foot
Castro-Martins, Pedro; Coelho, Luis; Vaz, Mário; Pinto, Marcelino; Marques, Maria ArcelinaDiabetic foot is a serious complication of diabetes that affects millions of people around the world. It is characterized by poor circulation, nerve damage and high plantar pressure that can lead to the development of foot ulcers and amputations. Offloading plantar pressure in certain regions is extremely important. In this paper we propose a preliminary methodology for a new concept of pneumatic insole for pla...
