Older children, teens, and adults need 3 cups* a day, while children 4 to 8 years old need 2½ cups, and children 2 to 3 years old need 2 cups.

Attachment patterns and suicidal behaviours on higher education students

Introduction: Every individual has a necessity to establish affective relationships throughout life in order to feel comfort and support. This need is called attachment and allows the human being to explore the world, acquiring knowledge about himself and everyone else(1) There are several changes that occur on students’ lives when enrolling and attending university, a period that is known to include a set of situational and academic transitions which might lead to mental health problems, and thus making students more vulnerable and more prone to develop suicidal behaviours. Objectives: To determine the prevalence of suicidal ideation on higher education students and to assess its relationship with attachment patterns. Methods: Quantitative, descriptive and correlational study, applied on a sample of 1074 students from a Portuguese higher education institution. Data collection was possible through an online platform that included a survey with questions regarding sociodemographical and academic profiling, the Portuguese version of the Adult Attachment Scale (EVA)(2) and the Suicidal Ideation Questionnaire(3) Results: Students’ age varies between the 17 and 49 ( = 23,9 years old ± 6,107 Sd), the vast majority (64.7%) are females. Results show that the presence/severity of suicidal thoughts is low ( = 13.84; ± 20.29 Sd) on a scale from 0 to 180 and cut-off point > 41 for values that suggest potential suicidal risk, and based on that, 84 students were identified (7,8%). We verified significant relationships between suicidal ideation and anxiety and attachment (r=0.314 p=0.000). Conclusions: Although there is not a high prevalence of suicidal ideation on students, we found 84 students in our sample (7,8%) that reveal a potential risk for suicide. The results also show that young students with safe attachment patterns display less suicidal ideation. Safe attachment patterns are essential on interpersonal and social relationships and play an important role during the academic period. We cannot be indifferent towards this issue due to its individual, familiar and social repercussions. Every higher education institution should then establish student support offices and develop mental health promotion programs as well as suicide prevention campaigns.

Evaluation of the protective effects of kolaviron on Kolanut-induced oxidative stress in developing rat brain

The brain is exposed throughout life to oxidative stress, and certain diseases of the brain and nervous system are thought to involve free radical processes and oxidative damage. This study is aimed at evaluating the effect of kolaviron on kolanut-induced oxidative stress in developing rat brain. Twenty-five adult pregnant Wistar rats weighing between 160 and 180g were used for the experiment. They were randomly divided into five groups of five animals each. The animals were fed with standard diets of mice cubes and water provided ad libitum. The control rats received water and cornoil, while the experimental animals received 200 mg/kg body weight of kolanut (kn), 200 mg/kg of kolaviron (kv), and 200 mg/kg body weight of vitamin E which served as a standard antioxidant with cornoil as vehicle orally in pre- and post-natal life. After birth, gross morphometry and behavioural changes of the pups of days 1, 7, 14, 21 and 28 postpartum were evaluated. Blood samples were collected from pups of day 21 for hematological, liver and renal function analyses, while the brains of pups of day 21 postpartum were preserved in phosphate buffer at a temperature of 4oC and pH 7.4 for biochemical analysis. There were significant alterations in the gross morphometry and behavioural parameters studied in the treated animals compared with the control at p< 0.05. There were elevated levels of RBC, WBC and platelets in the treated group compared with the control at p< 0.05. However, no significant change was observed in the PCV, Hb, liver and renal function parameters studied at p>0.05. A non-significant increase in levels of malondialdehyde, MDA, a bye-product of lipid peroxidation in the kolanut group was observed. However, administration of kolaviron and vitamin E non-significantly (p>0.05) reversed these changes. In conclusion, maternal consumption of kolanut induced mild oxidative stress and the administration of kolaviron and vitamin E decreased the rate at which kolanut induced oxidative stress in developing rat brain.

Biomimetic accommodating intraocular lens

The crystalline lens allows the eye to focus on near and far objects. During the aging process, it loses its ability to focus and often becomes cloudy during cataract formation. At this point, traditional medical therapy replaces the lens with an artificial replacement lens. Although replacement lenses for the crystalline lens have been implanted since 1949 for cataract surgery, none of the FDA-approved lenses mimic the anatomy of the natural lens. Hence, they are not able to focus in a manner similar to the youthful lens. Instead, they function in a manner similar to the aged lens and only provide vision at a single distance or at a very limited range of focal distances. Patients with the newest implants are often obliged to use reading glasses when using near vision, or suffer from optical aberrations, halos, or glare. Therefore, there is a need to provide youthful vision after lens surgery in terms of focusing ability, accurate optical power, and sharp focus without distortion or optical aberrations.

This thesis presents an approach to restoring youthful vision after lens replacement. An intraocular lens (IOL) that can provide accurate visual acuity along with focusing ability is proposed. This IOL relies on the natural anatomy and physiology of the eye, and therefore is actuated in a manner identical to the natural lens. In addition, the lens has the capability for adjustment during or after implantation to provide high-acuity vision throughout life.

The natural anatomy and physiology of the eye is described, along with lens replacement surgery. A lens design is proposed to address the unmet need of lens-replacement patients. Specific care in the design is made for small surgical incisions, high visual acuity, adjustable acuity over years, and the ability to focus similar to the natural lens. Methods to test the IOL using human donor tissue are developed based upon prior experiments on the ex vivo natural lens. These tools are used to demonstrate efficacy of the newly developed accommodating intraocular lens.

To further demonstrate implant feasibility, materials and processes for building the lens are evaluated for biocompatibility, endurance, repeatable manufacture, and stability. The lens biomechanics are determined after developing an artificial anatomy testing setup inspired by the natural anatomy of the human focusing mechanism. Finally, based upon a mechanical and optical knowledge of the lens, several improved lens concepts are proposed and demonstrated for efficacy.

Relação entre a prática deliberada e continuada da atividade física e o desempenho cognitivo, em idosos

A atividade física (AF) previne e atrasa o declínio cognitivo que se desenvolve com o envelhecimento (Middleton et al, 2010; Ratey & Loehr, 2011; WHO, 2012; Buckworth, 2013; Chang & Etnier, 2014). Este estudo tem como objectivo identificar a relação entre o número de horas de prática de AF, deliberada e continuada no tempo, e o desempenho cognitivo na população idosa. A amostra contém um n=43 (34♀, 9♂) com idades compreendidas entre os 60 e os 90 anos (69.7±7.77 anos), e com escolaridade de 7.4±3.8 anos. Os instrumentos usados foram o teste de Stroop que mediu o desempenho cognitivo (função executiva), o questionário YPAS que mediu a atividade física semanal e o guião de entrevista de prática deliberada que mediu o número de horas consecutivas de prática de atividade física (PDAF). Os resultados indicam que a variável PDAF correlaciona-se negativamente com o valor total do teste de Stroop (quanto mais baixo, melhor o desempenho), i.e. mais horas de prática deliberada e continuada de atividade física estão associados a um melhor desempenho cognitivo. Juntamente com o efeito bem demonstrado na prevenção de doença cardiovascular e metabólica, a prática deliberada e continuada de atividade física poderá ser importante para a melhoria da função cognitiva ao longo da vida.

Development of motor competence in childhood and adolescence

This dissertation aimed to investigate the development of motor competence in childhood and adolescence. As a starting point, a systematic review was conducted to investigate the instruments used for the evaluation of motor competence. This review identified a gap in the literature regarding the existence of an instrument to assess motor competence based on the three theoretical constructs (stability, locomotor, manipulative). In an attempt to fill this gap, a valid quantitative instrument was proposed. To meet this purpose, 584 children, between 6 and 14 years of age, were evaluated in nine motor tasks, three for each construct. The final instrument comprised two motor tasks for each construct (stability, locomotor, manipulative) and presented very good fit indexes. This instrument was used to analyse the motor competence behaviour by gender in different age groups, indicating that generally boys outperformed girls and both genders increased their performance across age groups. However, different motor competence growth rates appear in both genders across age groups. In addition, children with high and low motor competence were compared regarding some of their health related fitness variables. We found that, regardless of age and gender, the group with better motor proficiency always showed better results in health related fitness. We found positive moderate to high correlations between motor competence and the variables of cardiovascular fitness and muscular fitness, and an inverse correlation with body composition across the four age groups. We also found that motor competence explained 75% of the variance of the health related fitness for the total sample, with locomotion as the primary predictor. However, when analysing the four age groups, stability skills seem to play an important role in health related fitness in the transition from childhood to adolescence. In conclusion, educational and health policies should consider the development of motor competence as an essential strategy to promote healthy development throughout life.

Establishment and development of infant gut microbiota

The nascent gut microbiota at birth is established in concert with numerous developmental parameters. Here, in the INFAMTET study, we chronicled the impact of some factors which are key determinants of the infant gut microbiota, namely; mode of birth, gestational age, and type of feeding. We determined that the aggregated microbiota profile of naturally delivered, initially breastfed infants are relatively stable from one week to six months of age and are not significantly altered by increased duration of breastfeeding. Contrastingly, there is significant development of the microbiota profile of C-section delivered infants, and this development is significantly influenced by breastfeeding duration. Preterm infants, born by either mode of birth, initially have a high proportion of Proteobacteria, and demonstrate significant development of the gut microbiota from week 1 to later time-points. The microbiota is still slightly, but significantly, affected by birth mode at one year of age although no specific genera were found to be significantly altered in relative abundance. By two years of age, there is no effect of either birth mode or gestational age. However this does not preclude the possibility that symptoms developed later in life, which are associated with preterm or C-section birth, are as a result of the early perturbation of the neonatal gut microbiota. It is likely that the combination of relatively low exposure (breast fed), high exposure (formula fed) or delayed exposure (C-section and preterm) to specific antigens and the resulting inflammatory responses, in this crucial window of host-microbiota interaction, influence systemic health of the individual throughout life.

Graphene-based bioelectronic interfaces and devices and interpretative models targeting glial cells

Bioelectronic interfaces have significantly advanced in recent years, offering potential treatments for vision impairments, spinal cord injuries, and neurodegenerative diseases. However, the classical neurocentric vision drives the technological development toward neurons. Emerging evidence highlights the critical role of glial cells in the nervous system. Among them, astrocytes significantly influence neuronal networks throughout life and are implicated in several neuropathological states. Although they are incapable to fire action potentials, astrocytes communicate through diverse calcium (Ca2+) signalling pathways, crucial for cognitive functions and brain blood flow regulation. Current bioelectronic devices are primarily designed to interface neurons and are unsuitable for studying astrocytes. Graphene, with its unique electrical, mechanical and biocompatibility properties, has emerged as a promising neural interface material. However, its use as electrode interface to modulate astrocyte functionality remains unexplored. The aim of this PhD work was to exploit Graphene-oxide (GO) and reduced GO (rGO)-coated electrodes to control Ca2+ signalling in astrocytes by electrical stimulation. We discovered that distinct Ca2+dynamics in astrocytes can be evoked, in vitro and in brain slices, depending on the conductive/insulating properties of rGO/GO electrodes. Stimulation by rGO electrodes induces intracellular Ca2+ response with sharp peaks of oscillations (“P-type”), exclusively due to Ca2+ release from intracellular stores. Conversely, astrocytes stimulated by GO electrodes show slower and sustained Ca2+ response (“S-type”), largely mediated by external Ca2+ influx through specific ion channels. Astrocytes respond faster than neurons and activate distinct G-Protein Coupled Receptor intracellular signalling pathways. We propose a resistive/insulating model, hypothesizing that the different conductivity of the substrate influences the electric field at the cell/electrolyte or cell/material interfaces, favouring, respectively, the Ca2+ release from intracellular stores or the extracellular Ca2+ influx. This research provides a simple tool to selectively control distinct Ca2+ signals in brain astrocytes in neuroscience and bioelectronic medicine.

Requirements for the use of virtual worlds in corporate training : perspectives from the post-mortem of a corporate e-learning provider approach of Second Life and OpenSimulator

Between 2009 and 2011, a joint academia-industry effort took place to integrate Second Life and OpenSimulator platforms into a corporate elearning provider’s learning management platform. The process involved managers and lead developers at the provider and an academic engineering research team. We performed content analysis on the documents produced in this process, seeking data on the corporate perspective of requirements for virtual world platforms to be usable in everyday practice. In this paper, we present the requirements found in the documents, and detail how they emerged and evolved throughout the process.

Hematological parameters and anaerobic threshold in Brazilian soccer players throughout a training program

We assessed the responses of hematological parameters and their relationship to the anaerobic threshold of Brazilian soccer players during a training program. Twelve athletes were evaluated at the beginning (week 0, T1), in the middle (week 6, T2), and at the end (week 12, T3) of the soccer training program. On the first day at 7:30 AM, before collecting the blood sample at rest for the determination of the hematological parameters, the athletes were conducted to the anthropometric evaluation. On the second day at 8:30 AM, the athletes had their anaerobic threshold measured. Analysis of variance with Newman-Keuls`post hoc was used for statistical comparisons between the parameters measured during the soccer training program. Correlations between the parameters analyzed were determined using the Pearson`s correlation coefficient. Erythrocytes concentration, hemoglobin, and hematocrit were significantly increased from T1 to T2. The specific soccer training program led to a rise in erythrocytes, hemoglobin, and hematocrit from T1 to T2. We assumed that these results occurred due to the plasma volume reduction and may be explained by the soccer training program characteristics. Furthermore, we did not observe any correlation between the anaerobic threshold and the hematological parameters.

A 12-month randomized controlled trial of balance training in elderly women with ostebporosis: Improvement of quality of life

Objective: Physical and psychological incapacity, including fear of falling is related to decreased satisfaction with life in osteoporosis (OP). The impact of a balance exercise program on improving the quality of life is not well established. We have, therefore, investigated the effect of 12-month Balance Training Program in quality of life, functional balance and falls in elderly OP women. Methods: Sixty consecutive women with senile OP were randomized into a Balance Training Group (BT) of 30 patients and no intervention control group (CG) of 30 patients. The BT program included techniques to improve balance over a period of 12 months (1 h exercise session/week and home-based exercises). The quality of life was evaluated before and at the end of the trial using the Osteoporosis Assessment Questionnaire (OPAQ), functional balance was evaluated by Berg Balance Scale (BBS). Falls in the preceding year were noted and compared to the period of study. Results: The comparison of OPAQ variations (INITIAL-FINAL) revealed a significant improvement in quality of life in all parameters for BT compared to CG: well-being (1.61 +/- 1.44 vs. -1.46 +/- 1.32, p < 0001), physical function (1.30 +/- 1.33 vs. -0.36 +/- 0.82, p < 0.001), psychological status (1.58 +/- 1.36 vs. -1.02 +/- 0.83, p < 0.001), symptoms (2.76 +/- 1.96 vs. -0.63 +/- 0.87, p < 0.001), social interaction (1.01 +/- 1.51 vs. 0.35 +/- 1.08, p < 0.001). Of note, this overall benefit was paralleled by an improvement of BBS (-5.5 +/- 5.67 vs. +0.5 +/- 4.88 p < 0.001) and a reduction of falls in 50% in BT group vs. 26.6% for the CG (RR: 1.88, p < 0.025). Conclusion: The long-term Balance Training Program of OP women provides a striking overall health quality of life improvement in parallel with improving functional balance and reduced falls.

Knowledge of the Portuguese population on Basic Life Support and availability to attend training

OBJECTIVETo evaluate the level of knowledge and the availability of the Portuguese population to attend training in Basic Life Support (BLS) and identify factors related to their level of knowledge about BLS.METHODObservational study including 1,700 people who responded to a questionnaire containing data on demography, profession, training, interest in training and knowledge about BLS.RESULTSAmong 754 men and 943 women, only 17.8% (303) attended a course on BLS, but 95.6% expressed willingness to carry out the training. On average, they did not show good levels of knowledge on basic life support (correct answers in 25.9 ± 11.5 of the 64 indicators). Male, older respondents who had the training and those who performed BLS gave more correct answers, on average (p<0.01).CONCLUSIONThe skill levels of the Portuguese population are low, but people are available for training, hence it is important to develop training courses and practice to improve their knowledge.
