"You get out of the house, you talk to each other, you laugh…And that's fantastic" - a qualitative study about older people's perceptions of social prescribing in mainland Portugal.

Background: Social prescribing (SP) is a non-clinical approach, most commonly based in healthcare units, that aims to address non-medical health-related social needs by connecting individuals with community-based services. This qualitative study explores the perception of Portuguese older adults regarding the benefits of SP and their willingness to participate in SP initiatives.

Methods: Three face-to-face focus group sessions were conducted with 23 participants in different cities in Portugal.

Social prescribing for older adults in mainland Portugal: Perceptions and future prospects.

Background: In order to address health inequalities, which have been exacerbated by the COVID-19 pandemic, and promote older adults' quality of life, it is necessary to explore non-medical approaches such as social prescribing. Social prescribing is a person-centered approach that allows health professionals to refer patients to services provided by the social and community sectors. This study aimed to explore older adults' perceptions of social prescribing in mainland Portugal and to identify factors associated with these perceptions, providing insights for future implementation strategies.

Photocatalytic Performance of Sol-Gel Prepared TiO Thin Films Annealed at Various Temperatures.

Titanium dioxide (TiO) in the form of thin films has attracted enormous attention for photocatalysis. It combines the fundamental properties of TiO as a large bandgap semiconductor with the advantage of thin films, making it competitive with TiO powders for recycling and maintenance in photocatalytic applications. There are many aspects affecting the photocatalytic performance of thin film structures, such as the nanocrystalline size, surface morphology, and phase composition.

Nutritional counselling in adults promoting adherence to the Mediterranean diet as adjuvant in the treatment of major depressive disorder (INDEPT): a randomized open controlled trial study protocol.

Background: Major Depressive Disorder (MDD) is a leading cause of disability worldwide. Approximately one-third of patients with MDD do not respond to treatment, and often exhibit elevated inflammation biomarkers, which are associated with worse prognosis. Previous research has linked healthier dietary patterns, such as the Mediterranean Diet (MedDiet), with a lower risk of MDD and symptoms of depression, potentially due to their anti-inflammatory properties.

Health Literacy among Older Adults in Portugal and Associated Sociodemographic, Health and Healthcare-Related Factors.

Although the health literacy level of the general population was described recently, little is known about its specific levels among older adults in Portugal. Therefore, this cross-sectional study aimed to investigate the levels of health literacy demonstrated by older adults in Portugal and explore associated factors. Using a randomly generated list of telephone numbers, adults aged 65 years or more living in mainland Portugal were contacted in September and October 2022.

Exciton tuning in monolayer WSe substrate induced electron doping.

We report large exciton tuning in WSe monolayers substrate induced non-degenerate doping. We observe a redshift of ∼62 meV for the A exciton together with a 1-2 orders of magnitude photoluminescence (PL) quenching when the monolayer WSe is brought in contact with highly oriented pyrolytic graphite (HOPG) compared to dielectric substrates such as hBN and SiO. As the evidence of doping from HOPG to WSe, a drastic increase of the intensity ratio of trions to neutral excitons was observed.

Nutritional intake and malnutrition in institutionalised and non-institutionalised older adults.

Malnutrition (synonym: undernutrition) is prevalent among older adults, which may be partly related to changes in dietary intake, but evidence on the link between malnutrition and diet is scarce. The aims of this study were to estimate the association between energy/nutrients intake and malnutrition, and to characterise nutritional inadequacy in institutionalised and non-institutionalised older adults. A national survey was conducted including a Portuguese representative sample of nursing home (NH) residents ( 563) and community-dwellers ( 837) aged ≥ 65 years.

Understanding the Role of Different Substrate Geometries for Achieving Optimum Tip-Enhanced Raman Scattering Sensitivity.

Tip-enhanced Raman spectroscopy (TERS) has experienced tremendous progress over the last two decades. Despite detecting single molecules and achieving sub-nanometer spatial resolution, attaining high TERS sensitivity is still a challenging task due to low reproducibility of tip fabrication, especially regarding very sharp tip apices. Here, we present an approach for achieving strong TERS sensitivity via a systematic study of the near-field enhancement properties in the so-called gap-mode TERS configurations using the combination of finite element method (FEM) simulations and TERS experiments.

The association between dietary patterns and nutritional status in community-dwelling older adults-the PEN-3S study.

Background: Diet plays a key role in the ageing process. Despite this, little is known about the effect of dietary patterns on older adults' nutritional status. The main aim of this study was to analyse the association between a posteriori derived dietary patterns (DPs) and nutritional status among community dwellers aged ≥65.

Geriatric Assessment of the Portuguese Population Aged 65 and Over Living in the Community: The PEN-3S Study.

Introduction: As populations live longer, they also aim to live better. A crucial step for this is to improve the understanding about older adults' physical and psychological health. Therefore, the aim of the present study was to characterise the Portuguese population over-65 regarding nutritional status, cognitive function, functional status, symptoms of depression, and loneliness, by sex and age groups.

Association between living setting and malnutrition among older adults: The PEN-3S study.

Objectives: Malnutrition is frequent among older adults, especially those living in nursing homes, but the association between residential setting and nutritional status is controversial. The aim of this study was to examine the association between living setting (nursing home versus community) and malnutrition while adjusting for demographic, socioeconomic, health-related, and psychosocial factors.

Methods: This cross-sectional study included a randomly selected representative sample of Portuguese adults ≥65 y of age.

Is olive oil good for you? A systematic review and meta-analysis on anti-inflammatory benefits from regular dietary intake.

The prevalence of non-communicable diseases is rapidly increasing, and evidence shows that diet and lifestyle are key areas of intervention to decrease their burden. Olive oil is considered one of the key nutritional components responsible for the benefits of the Mediterranean diet, which is characterized by the use of olive oil in meals as the main source of fat; a high consumption of water, fruits, nuts, vegetables, legumes, whole grains, spices, and herbs; a moderate consumption of dairy products (mainly cheese and yogurt), fish, poultry, and red wine; and a reduced consumption of red meat and processed foods. The aim of this review was to summarize evidence from randomized controlled trials on the effect of regular dietary intake of olive oil on three inflammatory markers: C-reactive protein, interleukin-6, and tumor necrosis factor-α.

Malnutrition among older adults living in Portuguese nursing homes: the PEN-3S study.

Objective: To characterise the nutritional status and to identify malnutrition-associated variables of older adults living in Portuguese nursing homes.

Design: Cross-sectional study. Data on demographic and socio-economic characteristics, self-reported morbidity, eating-related problems, nutritional status, cognitive function, depression symptoms, loneliness feelings and functional status were collected by trained nutritionists through a computer-assisted face-to-face structured interview followed by standardised anthropometric measurements.

Gender differences in psychosocial determinants of self-perceived health among Portuguese older adults in nursing homes.

Self-perceived health declines with age, varies by gender and is a predictor of mortality, morbidity, physical and psychological functioning. However, gender differences in health and illness perception are complex and not yet fully understood. This study aimed to explore gender-related differences in psychosocial determinants of self-perceived health among older adults living in nursing homes.

Interatomic Coulombic Decay: The Mechanism for Rapid Deexcitation of Hollow Atoms.

The impact of a highly charged ion onto a solid gives rise to charge exchange between the ion and target atoms, so that a slow ion gets neutralized in the vicinity of the surface. Using highly charged Ar and Xe ions and the surface-only material graphene as a target, we show that the neutralization and deexcitation of the ions proceeds on a sub-10 fs time scale. We further demonstrate that a multiple Interatomic Coulombic Decay (ICD) model can describe the observed ultrafast deexcitation.

Self-Regulation of Weight After Sleeve Gastrectomy.

Bariatric surgery is recognized as the most effective method for achieving relevant weight loss in subjects with severe obesity. However, there is insufficient knowledge about weight self-regulation and quality of motivation in these patients. The main goal of this study was to characterize the association between the percentage of excess weight loss (%EWL) and the motivation to manage weight, at least 1 year after sleeve gastrectomy (SG).

National survey of the Portuguese elderly nutritional status: study protocol.

Background: Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns.

Effects of a constructional intervention on airborne and deposited particulate matter in the Portuguese National Tile Museum, Lisbon.

In the 1970s, a large ambulatory of the National Tile Museum, Lisbon, was closed with glass panes on both ground and first floor. Although this design was meant to protect the museum collection from ambient air pollutants, small openings between the glass panes remain, creating a semi-enclosed corridor. The effects of the glass panes on the indoor air quality were evaluated in a comparative study by monitoring the airborne particle concentration and the extent of particle deposition at the enclosed corridor as well as inside the museum building.
