- Effect of educational sessions directed to musculoskeletal disorders on health literacy and on the kyohotic and lordotic indexes in employers of the CESPU group: Pilot studyPublication . Costa, Marlene da; Costa, Nuno da; Fonseca, André; Lopes, Sofia; Coelho, Ana; Rocha, Paula ; Brochado, Gabriela; Vieira, ÁgataDue to technological advance in developed countries, there has been an evolution of workplaces which, in turn, has increased the adherence to the “sitting position” in the workplace, consequently leading to an increase in the incidence of musculoskeletal disorders (MSDs). Currently, physiotherapy has shown an important role, through health literacy, not only in the treatment but also in the prevention of MSDs. Aim of work. To evaluate the effect of educational sessions aimed at MSDs on health literacy and on the indices of the thoracic and lumbar region curvatures, in a population of employers of the Cooperativa de Ensino Superior Politécnico e Universitário (CESPU) group. A pilot study:quasi-experimental was conducted on 22 employers of the CESPU group. They were allocated into two groups, the Experimental (N = 12), which was subject to the educational sessions, aimed at posture and prevention of MSDs, and the Control (N = 10), consisting of employers who showed no interest in attending the educational sessions. A sociodemographic questionnaire was applied to characterise the sample, a Quiz, in validation process, with the purpose of assessing the level of literacy of the employers in an educational and interactive way, and the Flexicurve, with the purpose of assessing the physiological curvature of the thoracic and lumbar regions, before and one week after the educational activities. Data were analysed using the IBM® SPSS® software,with a confidence interval of 95%. Results. No statistically significant differences were found in the values of the kyphotic and lordotic indexes, between the two groups. Statistically significant differences were found, in the intragroup analysis (between the two moments of assessment) in the Total Score, assessed by the Quiz, for the experimental group (p = 0.005). This study concluded that there seems to be no effect of the educational sessions on the curvatures of the thoracic and lumbar regions of the employers of the CESPU group. However, the results seem to show a positive effect of the educational sessions on the Total Score, which may suggest an increase in the level of health literacy.
- Influence of educational sessions on musculoskeletal disorders on sleep quality and sleep literacy in health school group employers: Pilot studyPublication . Antoni, Aurore; Lopes, Sofia; Coelho, Ana; Rocha, Paula; Brochado, Gabriela; Vieira, ÁgataOccupational diseases, especially musculoskeletal disorders (MSDs) are a major factor in our health. Behaviour during the working day can influence the quality of our night. The lack of prevention and information about MSDs and their relationship with the quality of sleep weakens the quality of life and the health of people. As specific objectives, we want to verify if there is an association and correlation between the socio-demographic variables, gender, age, academic qualifications, physical activity, daily sitting time and BMI with the sleep quality index. A quasi-experimental pilot study was conducted on 21 health school employers. They were allocated in two groups, the Experimental The educational sessions did not improve the participants’ sleep quality and sleep literacy. Associations between sociodemographic factors and sleep quality were not found. (N = 11), which was subjected to educational sessions, and the Control (N = 10), constituted of the employers who were not interested in attending the educational sessions. A pilot study was carried out, where the sample characterization and selection questionnaire were tested and validated. The Pittsburgh Sleep Quality Index and the quiz on sleep literacy were used as instruments for all participants. The analysis and treatment of the collected results was carried out using version 28 of the IBM® SPSS® software, with a confidence interval of 95%. There was no statistically significant improvement in the global quality of sleep intergroup (p = 0.314). No significant differences were found between the experimental group and the control group regarding intra-group score differences between the two moments (p = 0.863 and p = 0.756, respectively). Comparing the two groups there was no statistically significant increase in the quiz scores before and after the intervention (p = 0.809). Also in the intragroup analysis, there was no increase in knowledge between the two moments. The results showed no statistically significant differences regarding the associations and correlations of the sociodemographic variables with sleep quality. The educational sessions did not improve the participants’ sleep quality and sleep literacy. Associations between sociodemographic factors and sleep quality were not found.

- Neural control of the lower urinary tract during hydrocephalusPublication . Louçano, Marta; Coelho, Ana; Chambel, Sílvia; Cruz, Célia Duarte; Tavares, IsauraNeurological impairments may affect the neural control of the Lower Urinary Tract (LUT), due to structural and functional changes. Hydrocephalic patients usually present a triad of symptoms, which include gait disturbances, dementia and urinary incontinence. The consequences of hydrocephalus in brain structures, namely those involved in neural control of micturition remain mostly unknown. We used a validated animal model of hydrocephalus (rats injected in the cisterna magna with kaolin) to study the neuronal control of the LUT in hydrocephalus, focusing on two circumventricular areas: the Locus Coeruleus (LC) and the Periaqueductal grey (PAG). Studying neuronal activation of the PAG, a decrease in the number of fos-immunoreactive IR cells in the group of hydrocephalic animals was observed. Analysing the different column of the PAG separately, it was observed that this reduction was statistically significant only in ventrolateral PAG (VLPAG). During hydrocephalus the levels of tyrosine hydroxylase (TH, enzyme involved in noradrenaline biosynthesis) increase in the LC, which may affect surrounding areas, namely the Pontine Micturition Center (PMC). To analyse if hydrocephalic animals present changes in noradrenaline levels at the spinal cord which may affect micturition, the expression of dopamine beta-hydroxylase (DBH), another enzyme involved in noradrenaline biosynthesis, in L6 spinal cord sections, was evaluated by immunohistochemistry. Hydrocephalic animals showed a higher number of fibres immunoreactive to DBH. Cystometric analysis of hydrocephalic animals, 8 weeks after induction, was used to evaluate the bladder’s function. It was found that hydrocephalic animals show an increase both in the number of bladder contractions and of minimum pressure. These results suggest alterations in the brain-bladder control network leading to an exaggerated micturition reflex. Considering the significant role of PAG in the voiding reflex, its lower activation may lead to miscommunication with other areas involved in the network, namely the PMC or LC. Noradrenergic projections from the LC are responsible for the coordination between bladder contractions and EUS relaxation during voiding. Our study shows an increase in the levels of DBH in the Onuf’s nucleus. It is possible that the increased availability of the limiting enzyme in the synthesis of noradrenaline contributes to the increased number of bladder contractions during hydrocephalus.
- Noradrenergic pathways involved in micturition in an animal model of hydrocephalus—Implications for urinary dysfunctionPublication . Louçano, Marta; Coelho, Ana; Chambel, Sílvia Sousa; Prudêncio, Cristina; Cruz, Célia Duarte; Tavares, IsauraHydrocephalus is characterized by enlargement of the cerebral ventricles, accompanied by distortion of the periventricular tissue. Patients with hydrocephalus usually experience urinary impairments. Although the underlying etiology is not fully described, the effects of hydrocephalus in the neuronal network responsible for the control of urination, which involves periventricular areas, including the periaqueductal gray (PAG) and the noradrenergic locus coeruleus (LC). In this study, we aimed to investigate the mechanisms behind urinary dysfunction in rats with kaolin-induced hydrocephalus. For that purpose, we used a validated model of hydrocephalus—the rat injected with kaolin in the cisterna magna—also presents urinary impairments in order to investigate the putative involvement of noradrenergic control from the brain to the spinal cord Onuf’s nucleus, a key area in the motor control of micturition. We first evaluated bladder contraction capacity using cystometry. Since our previous characterization of the LC in hydrocephalic animals showed increased levels of noradrenaline, we then evaluated the noradrenergic innervation of the spinal cord’s Onuf’s nucleus by measuring levels of dopamine β-hydroxylase (DBH). We also evaluated the expression of the c-Fos protooncogene, the most widely used marker of neuronal activation, in the ventrolateral PAG (vlPAG), an area that plays a major role in the control of urination by its indirect control of the LC via pontine micturition center. Hydrocephalic rats showed an increased frequency of bladder contractions and lower minimum pressure. These animals also presented increased DBH levels at the Onuf´s nucleus, along with decreased c-Fos expression in the vlPAG. The present findings suggest that impairments in urinary function during hydrocephalus may be due to alterations in descending noradrenergic modulation. We propose that the effects of hydrocephalus in the decrease of vlPAG neuronal activation lead to a decrease in the control over the LC. The increased availability of noradrenaline production at the LC probably causes an exaggerated micturition reflex due to the increased innervation of the Onuf´s nucleus, accounting for the urinary impairments detected in hydrocephalic animals. The results of the study provide new insights into the neuronal underlying mechanisms of urinary dysfunction in hydrocephalus. Further research is needed to fully evaluate the translational perspectives of the current findings.

- The impact of clinical pilates exercises on tension-type headaches: A case seriesPublication . Leite, Agathe; Matignon, Antoine; Marlot, Léa; Coelho, Ana; Lopes, Sofia; Brochado, GabrielaTension-type-headaches appear as the third most common disease in the general population and have a big impact on quality of life. The aim is to verify the impact of clinical Pilates exercises on pain intensity, impact headaches, neck disability, state of anxiety, depression, stress and quality of sleep in higher-education students. After a sample selection questionnaire was completed, a series of cases was carried out with 9 undergraduate students with tension-type headaches. Five instruments were applied before and after an intervention program: (i) Numerical Rating Scale—NRS, (ii) Headache Impact Test—HIT-6™, (iii) Neck Disability Index, (iv) Depression, Anxiety, Stress Scales and (v) Pittsburgh Sleep Quality Index. Four sessions of 30 min classes of Pilates exercises were held for 2 weeks. The pain intensity decreased in only 2 participants. The impact of tension-type headaches on normal daily life and ability to function was improved in all patients, and only one patient’s functional disability caused by pain in the cervical region did not improve. In regard to negative emotional states, 6 individuals reported improvements, and only one individual reported a lower quality of sleep after the program. The exercise program can induce positive effects on disorders associated with tension-type-headaches.
