Work-related self-reported musculoskeletal injuries in Portuguese hypermarket cashiers

Background:Work-related musculoskeletal disorders are a group of painful disorders which arise from work situations with continuous repetitive movements, carried out with speed and without time for recovery. In the performance of their job tasks, supermarket cashiers are exposed to this type of ergonomic stress.Objectives:This study aimed to determine the incidence of self-reported injuries in Portuguese hypermarket cashiers and to identify the related factors.Methods:The sample included 176 hypermarket cashiers, aged between 18 and 65 years (39.57±11.11), 167 (94.9%) of them women. Symptoms and exposure of interest have been collected through an interview-based questionnaire. The presence of carpal tunnel syndrome was assessed by Phalen’s test.Results:One hundred and seventeen (66.5%) cashiers reported an injury during employment, 100 (56.8%) of them reporting an injury in the previous 6 months. A total of 166 injuries were reported, corresponding to 1.14 injuries per 1,000 hours of work. The most common injuries were non-specific pain (30.4%), located in the shoulder (23.2%), cervical (22%) and lumbar spine (22%). Part-time workers showed a 2.25 times greater risk of injury (95% CI: 1.17-4.32; p=0.015) than full-time workers. Cashiers with more than 6 years of employment length had a 3.59 times higher risk of injury (95% CI: 1.84-6.99; p≤0.001) than those who had been working for a shorter period.Conclusions:Our data showed a high rate of reported injuries among hypermarket cashiers, especially among part-time workers and those with the highest length of employment.Key words: Epidemiology, incidence, injury, prevalence, supermarket cashiers     

Dietary Fatty Acids and Other Nutrients in Relation to Inflammation and Particularly to Oral Mucosa Inflammation. A Literature Review

Oral mucosa is site of inflammatory process development. When they are chronic, they provide a microenvironment based on cytokines and inflammatory mediators that contribute to cancer initiation, progression, invasion, and metastasis. Certain dietary fatty acids (FAs) have immunomodulatory, inflammatory, and antiinflammatory effects. This review examined the literature on inflammation, mainly referred to the oral mucosa, and its association with dietary FAs and other nutrients. A Pubmed search of studies published in English until June 2018 was carried out. N-3 FAs have shown immunomodulatory and antiinflammatory activity in certain human diseases. These FAs and their mediators may inhibit inflammation, angiogenesis, and cancer via multiple mechanisms. Studies on cellular models of murine and human intestinal mucosa indicate association between dietary n-3?FA intake and the inflammatory state of mucosa membranes. Nevertheless scarce information on the association between dietary FAs and oral inflammation could be found. Based on the evidence, we hypothesize that n-3 FAs reduce the oral mucosa inflammation thus decreasing the risk of developing precancerous lesions and cancer. Molecular and clinical studies referred to this topic should be carried out as a contribution to the oral cancer prevention.     

Placental metal concentrations and birth outcomes: The Environment and Childhood (INMA) project

Objective

To examine the association of placental levels of arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), manganese (Mn), and chromium (Cr) with birth outcomes (birth weight, length, and head circumference, low birth weight [LBW], gestational age, preterm delivery, and small for gestational age [SGA]) in mother-child pairs from the Environment and Childhood (INMA) Project in Spain.

Manejo de la enfermedad de Parkinson y otros trastornos del movimiento en mujeres en edad fértil: Parte 1

IntroductionThe main challenge of Parkinson's disease in women of childbearing age is managing symptoms and drugs during pregnancy and breastfeeding. The increase in the age at which women are having children makes it likely that these pregnancies will become more common in future.ObjectivesThis study aims to define the clinical characteristics of women of childbearing age with Parkinson's disease and the factors affecting their lives, and to establish a series of guidelines for managing pregnancy in these patients.ResultsThis consensus document was developed through an exhaustive literature search and a discussion of the available evidence by a group of movement disorder experts from the Spanish Society of Neurology.ConclusionsParkinson's disease affects all aspects of sexual and reproductive health in women of childbearing age. Pregnancy should be well planned to minimise teratogenic risk. A multidisciplinary approach should be adopted in the management of these patients in order to take all relevant considerations into account.     

Implantation of an Atrial Flow Regulator in a Child on Venoarterial Extracorporeal Membrane Oxygenator as a Bridge to Heart Transplant: A Case Report

BackgroundBalloon dilation and stenting of the atrial septum are techniques used to unload left heart cavities in acute or end-stage heart failure in children. However, they carry significant risks such as tamponade or device embolization.Case PresentationWe report the first case of a child with an end-stage mitochondrial cardiomyopathy on a venoarterial extracorporeal membrane oxygenator as a bridge to heart transplant where an atrial flow regulator device has been implanted.ConclusionsThis case illustrates the feasibility and safety of atrial flow regulator implantation in this setting. This procedure allowed to wean inotropic support while awaiting heart transplantation.
