Age-Related Variations in Breast Cancer Complications: Insights from Physical Medicine and Rehabilitation Clinical Practice.

Background Breast cancer patients often experience complications related to the disease or its treatment. With the rising average life expectancy, age is becoming less of a factor in treatment decisions for this condition. This study aims to evaluate differences in breast cancer complications among various age groups in patients referred to a hospital's physical medicine and rehabilitation (PMR) department. Methodology A retrospective study was conducted among all breast cancer patients evaluated in a PMR department between November 2019 and March 2021. Data were collected from patients' clinical files. SPSS® version 24 (IBM Corp., Armonk, NY, USA) was used for data analysis. Results We assessed 85 patients with a mean age of 56 years, finding that shoulder pain was the primary referral reason, reported by 85.9% of patients, followed by lymphedema in 32% of cases. Patients aged 56-65 years exhibited greater deficits in shoulder mobility compared to those between 66 and 75 years old, as well as greater functional limitations compared to other age groups. Most patients reported symptoms post-surgery, with an average delay of 24 months in PMR consultation. Despite this, nearly all patients (89.3%) reported clinical improvement following interventions. Conclusions We found that individuals in the 56-65-year age group were more prone to develop functional and shoulder mobility limitations. Despite delayed consultation, the majority of patients experienced clinical improvement, highlighting the intervention effectiveness of PMR interventions. These findings suggest that age alone may not be a determining factor in the reported breast cancer sequelae, implying the influence of other contributing factors in patient management. Further research is needed to elucidate the underlying mechanisms contributing to the diverse burden of disease sequelae observed across different age groups and to devise tailored interventions.

The design and implementation of a novel music-based curriculum for dementia care professionals: The experience of SOUND in Italy, Portugal and Romania.

BACKGROUND: The positive effects of active and passive music activities on older people with dementia are well and largely documented by the literature. Nevertheless, the use of music as a non-pharmacological intervention is not so common both in private and public older people care facilities because in-home staff have no competencies for delivering such activities. Conversely, the realization and implementation of a co-designed music-based curriculum for dementia care professionals may help the diffusion of music in the older people care facilities. This study was aimed at evaluating the learning outcomes of the SOUND training, based on an original co-designed music-based curriculum for dementia care professionals and implemented in Italy, Portugal and Romania. METHODS: The SOUND training study was developed through three phases: a) the co-design of the music-based curriculum for dementia care professionals, involving 55 people in the three participating countries; b) the teaching of the training curriculum to 63 dementia care professionals (29 in Italy, 17 in Portugal and 17 in Romania), delivered both in person and via a Moodle platform named Virtual Music Circle; c) the learning outcomes assessment, carried out by means of 13 self-evaluation tests, and a practical test, and the trainees' course evaluation by a questionnaire. RESULTS: Most of the trainees reached the highest score in the evaluation of the theoretical competencies in the three study countries. Conversely, some practical competencies in the facilitation of music activities need to be fine-tuned. The SOUND training course was evaluated very positively in the overall structure, theoretical contents, and practical workshops by the trainees. Nevertheless, they preferred the face-to-face compared to the distance learning methodology in the three countries. CONCLUSIONS: The SOUND training curriculum was effective in teaching music techniques and neurocognitive knowledge to dementia care professionals. Nevertheless, future courses should be differentiated for dementia care professionals with or without previous music knowledge and competencies. Moreover, the course is fully sustainable, because it does not require additional costs given that the curriculum is fully accessible online and it is also replicable because it trains professionals who can continue to apply the method in their working routine.

The link between obesity and the gut microbiota and immune system in early-life.

In early-life, the gut microbiota is highly modifiable, being modulated by external factors such as maternal microbiota, mode of delivery, and feeding strategies. The composition of the child's gut microbiota will deeply impact the development and maturation of its immune system, with consequences for future health. As one of the main sources of microorganisms to the child, the mother represents a crucial factor in the establishment of early-life microbiota, impacting the infant's wellbeing. Recent studies have proposed that dysbiotic maternal gut microbiota could be transmitted to the offspring, influencing the development of its immunity, and leading to the development of diseases such as obesity. This paper aims to review recent findings in gut microbiota and immune system interaction in early-life, highlighting the benefits of a balanced gut microbiota in the regulation of the immune system.

Stretch-induced compliance mechanism in pregnancy-induced cardiac hypertrophy and the impact of cardiovascular risk factors.

Pressure overload-induced hypertrophy compromises cardiac stretch-induced compliance (SIC) after acute volume overload (AVO). We hypothesized that SIC could be enhanced by physiological hypertrophy induced by pregnancy's chronic volume overload. This study evaluated SIC-cardiac adaptation in pregnant women with or without cardiovascular risk (CVR) factors. Thirty-seven women (1st trimester, 1stT) and a separate group of 31 (3rd trimester, 3rdT) women [healthy or with CVR factors (obesity and/or hypertension and/or with gestational diabetes)] underwent echocardiography determination of left ventricular end-diastolic volume (LVEDV) and E/e' before (T0), immediately after (T1), and 15 min after (T2; SIC) AVO induced by passive leg elevation. Blood samples for NT-proBNP quantification were collected before and after the AVO. Acute leg elevation significantly increased inferior vena cava diameter and stroke volume from T0 to T1 in both 1stT and 3rdT, confirming AVO. LVEDV and E/e' also increased immediately after AVO (T1) in both 1stT and 3rdT. SIC adaptation (T2, 15 min after AVO) significantly decreased E/e' in both trimesters, with additional expansion of LVEDV only in the 1stT. NT-pro-BNP increased slightly after AVO but only in the 1stT. CVR factors, but not parity or age, significantly impacted SIC cardiac adaptation. A distinct functional response to SIC was observed between 1stT and 3rdT, which was influenced by CVR factors. The LV of 3rdT pregnant women was hypertrophied, showing a structural limitation to dilate with AVO, whereas the lower LV filling pressure values suggest increased diastolic compliance.NEW & NOTEWORTHY The sudden increase of volume overload triggers an acute myocardial stretch characterized by an immediate rise in contractility by the Frank-Starling mechanism, followed by a progressive increase known as the slow force response. The present study is the first to characterize echocardiographically the stretch-induced compliance (SIC) mechanism in the context of physiological hypertrophy induced by pregnancy. A distinct functional adaptation to SIC was observed between first and third trimesters, which was influenced by cardiovascular risk factors.

A quasi-experimental mixed-method pilot study to check the efficacy of the "SOUND" active and passive music-based intervention on mental wellbeing and residual cognition of older people with dementia and dementia professionals' burnout: a research protocol.

Purpose: The SOUND method offers an innovative blended intervention based on music circle-activities and cognitive stimulation approaches which was co-designed by musicians, health professionals, older people with dementia, family caregivers and researchers, for its application in dementia settings. The purpose of the paper is to describe the detailed procedure of the quasi-experimental pilot study. Method: The experimental phase of SOUND uses a mixed-method design encompassing qualitative and quantitative observations, cognitive testing, self-report and interviewer-assisted questionnaires to investigate the effectiveness of the intervention for 45 people with dementia and 45 professionals (15 in every study country: Italy, Portugal, Romania). Results: The pilot study will be the first implementation of the SOUND intervention aiming to investigate the feasibility and preliminary effects of the method. Conclusion: The novelty of SOUND is its multicomponent method, including the most evidenced features for improving the wellbeing of participants.

The impact of echocardiographic indexation to evaluate cardiac reverse remodeling throughout pregnancy and postpartum.

INTRODUCTION AND OBJECTIVES: Echocardiography guidelines suggest normalizing left ventricular (LV) volumes and mass (LVM) to body size. During pregnancy, continuous weight variation impacts on body surface area (BSA) calculation, limiting the longitudinal analysis of cardiac remodeling (CR) and reverse remodeling (RR) variables. Our aim was to identify the most common indexing methodologies in the literature on pregnant populations through a systematic review; and, to compare four scaling methods: (i) none (absolute values); (ii) indexing to the BSA before pregnancy; (iii) allomeric indexing; and (iv) indexing to BSA measured at the same day of cardiac assessment, using an illustrative example. METHODS: We performed a systematic review of CR and RR during pregnancy and post-partum, using two databases. We included studies reporting longitudinal echocardiographic analysis of cardiac chamber volumes in humans. We used a prospective cohort study of healthy pregnant women who underwent four echocardiographic evaluations during pregnancy and postpartum, as an illustrative example. RESULTS: Twenty-seven studies were included, most studies indexed to BSA measured at each evaluation moment (n=21). Within-subjects design was the most reported to analyse longitudinal data (n=17). Indexation to the pre-pregnancy BSA or application of allometric indexes revealed a higher effect than BSA measured at each evaluation and an equal effect to not indexing using within-subjects design. The within-subjects designs also revealed a higher effect size value than the between-subjects design for longitudinal analysis of LVM adaptations during pregnancy and postpartum. CONCLUSION(S): This study concludes that indexation methods do not impact the clinical interpretation of longitudinal echocardiographic assessment but highlights the need to harmonize normalization procedures during pregnancy.

Oral microbiome characterization in oral mucositis patients-A systematic review.

BACKGROUND: Oral mucositis (OM) is a severe and common adverse effect of cancer treatment. The oral microbiome appears to play a role on the onset and severity of OM. Therefore, this systematic review aims to characterize the oral dysbiosis associated with OM. METHODS: The PRISMA checklist was followed and PubMed, Web of Science, and Scopus were screened for clinical studies characterizing the oral microbiome alterations in patients with OM. RESULTS: From a total of 2500 articles retrieved, we included nine articles in this systematic review. Certain types of bacteria, as Fusobacterium, were recognized as predictors of the onset of OM. In addition, it was reported that patients with severe OM presented a reduction in alpha-diversity, an increase in beta-diversity. The abundance of some taxa significantly changed with OM severity, with Bacillota phylum and genera Leptotrichia, Actinomyces, and Prevotella decreasing and Treponema increasing with disease progression. Additionally, during cancer treatment, changes in the oral microbiome have been observed in OM patients, with an increase in Candida and nosocomial pathogens, including Staphylococcus species. CONCLUSION: Our review indicates that cancer treatment can significantly alter the oral microbiome, with more pronounced changes observed in patients with severe OM in all relevant oral phyla, but more pronounced in Bacillota phylum.

The contribution of maternal factors to the oral microbiota of the child: Influence from early life and clinical relevance.

The mother represents one of the earliest sources of microorganisms to the child, influencing the acquisition and establishment of its microbiota in early life. However, the impact of the mother on the oral microbiota of the child from early life until adulthood remains to unveil. This narrative review aims to: i) explore the maternal influence on the oral microbiota of the child, ii) summarize the similarity between the oral microbiota of mother and child over time, iii) understand possible routes for vertical transmission, and iv) comprehend the clinical significance of this process for the child. We first describe the acquisition of the oral microbiota of the child and maternal factors related to this process. We compare the similarity between the oral microbiota of mother and child throughout time, while presenting possible routes for vertical transmission. Finally, we discuss the clinical relevance of the mother in the pathophysiological outcome of the child. Overall, maternal and non-maternal factors impact the oral microbiota of the child through several mechanisms, although the consequences in the long term are still unclear. More longitudinal research is needed to unveil the importance of early-life microbiota on the future health of the infant.

Cardiovascular risk factors during pregnancy impact the postpartum cardiac and vascular reverse remodeling.

Pregnant women with cardiovascular risk (CVR) factors are highly prone to develop cardiovascular disease later in life. Thus, recent guidelines suggest extending the follow-up period to 1 yr after delivery. We aimed to evaluate cardiovascular remodeling during pregnancy and determine which CVR factors and potential biomarkers predict postpartum cardiac and vascular reverse remodeling (RR). Our study included a prospective cohort of 76 healthy and 54 obese and/or hypertensive and/or with gestational diabetes pregnant women who underwent transthoracic echocardiography, pulse-wave velocity (PWV), and blood collection at the 1st trimester (1T) and 3rd trimester (3T) of pregnancy as well as at the 1st/6th/12th mo after delivery. Generalized linear mixed-effects models was used to evaluate the extent of RR and its potential predictors. Pregnant women develop cardiac hypertrophy, as confirmed by a significant increase in left ventricular mass (LVM). Moreover, ventricular filling pressure (E/e') and atrial volume increased significantly during gestation. Significant regression of left ventricular (LV) volume, LVM, and filling pressures was observed as soon as 1 mo postpartum. The LV global longitudinal strain worsened slightly and recovered at 6 mo postpartum. PWV decreased significantly from 1T to 3T and normalized at 1 mo postpartum. We found that arterial hypertension, smoking habits, and obesity were independent predictors of increased LVM during pregnancy and postpartum. High C-reactive protein (CRP) and low ST2/IL33-receptor levels are potential circulatory biomarkers of worse LVM regression. Arterial hypertension, age, and gestational diabetes positively correlated with PWV. Altogether, our findings pinpoint arterial hypertension as a critical risk factor for worse RR and CRP, and ST2/IL33 receptors as potential biomarkers of postpartum hypertrophy reversal.NEW & NOTEWORTHY This study describes the impact of cardiovascular risk factors (CVR) in pregnancy-induced remodeling and postpartum reverse remodeling (up to 1 yr) by applying advanced statistic methods (multivariate generalized linear mixed-effects models) to a prospective cohort of pregnant women. Aiming to extrapolate to pathological conditions, this invaluable "human model" allowed us to demonstrate that arterial hypertension is a critical CVR for worse RR and that ST2/IL33-receptors and CRP are potential biomarkers of postpartum hypertrophy reversal.

The Role of Biotics as a Therapeutic Strategy for Oral Mucositis - A Systematic Review.

OBJECTIVES: Oral mucositis (OM) is an acute and highly prevalent side effect of cancer treatments. Currently, there is no effective strategy for its prevention or treatment. This systematic review aimed to assess the effectiveness of biotics used as a therapeutic strategy for the management of OM. MATERIALS AND METHODS: The PRISMA checklist was followed and PubMed, Web of Science, and Scopus were screened for clinical and pre-clinical studies assessing the potential effects of biotics in OM. Inclusion criteria included in vivo studies related to oral mucositis evaluating the effect of biotics, and written in Portuguese, English, French, Spanish, or Dutch. The following exclusion criteria were used: systematic reviews and meta-analyses, reviews, case reports, opinion papers or comments, conference papers, letters without results, articles not related to oral therapy-induced mucositis or biotics, or in vitro articles that do not simulate oral mucositis. RESULTS: From a total of 1250 articles retrieved, 9 were included in this systematic review. Four clinical studies reported a reduction in oral mucositis occurrence with Lactobacillus species (Lactobacillus casei and Lactobacillus brevis CD2) and Bacillus clausii UBBC07. In pre-clinical studies, Lactococcus lactis genetically modified and Lactobacillus reuteri reduced the severity of OM and Streptococcus salivarius K12 also decreased the size of the ulcers. CONCLUSION: The findings of this systematic review suggest that probiotic supplementation may potentially reduce the incidence of therapy-induced OM and decrease its severity in patients undergoing cancer treatment. However, the available evidence is marred by significant heterogeneity across studies.

The PERInatal MYocardial Remodeling (PERIMYR) cohort study protocol: A prospective study of cardiac remodeling and "recovery" in pregnancy as a model to understand the impact of comorbidities in cardiac remodeling and reverse remodeling.

INTRODUCTION: Heart failure (HF) is among the leading causes of morbidity and mortality worldwide. Several conditions trigger left ventricular chronic pressure or volume overload, hypertrophy, systolic and diastolic dysfunction, leading to cardiac remodeling and a rapid progression toward HF. Therapeutic interventions elicit reverse remodeling (RR), a highly variable myocardial response that ranges from none to total ventricular structural/functional recovery. However, HF patients present several comorbidities and medications that mask a comprehensive molecular knowledge of RR and hinder the identification of potential biomarkers of its progression or prognosis. Therefore, instead of using this heterogeneous population or even animal models to understand myocardial remodeling, we propose studying pregnancy-induced cardiovascular remodeling and postpartum-induced RR. OBJECTIVES: To assess cardiovascular functional and structural adaptations during pregnancy and in postpartum, characterizing the associated molecular changes; as well as to explore the impact of hypertension, obesity and diabetes on these processes. METHODS: We will perform echocardiography and assess endothelial function and arterial stiffness (EndoPAT® and pulse wave velocity, respectively) and assess potential markers of remodeling and RR using plasma and urine samples from pregnant women. To translate to a HF context, we will determine the impact of risk factors (hypertension, obesity and diabetes) by studying subgroups of pregnant women with these comorbidities. RESULTS: Not applicable. CONCLUSION: We are convinced that understanding the impact of these comorbidities in such a homogeneous population, such as pregnant women, provides a valuable model to unveil the most relevant pathologic and often masked signaling pathways underlying cardiac remodeling and incomplete RR in a heterogeneous population, such as HF patients. Moreover, we expect to identify potential novel biomarkers of RR progression/prognosis more easily.

Vertical Transmission and Antifungal Susceptibility Profile of Yeast Isolates from the Oral Cavity, Gut, and Breastmilk of Mother-Child Pairs in Early Life.

Yeast acquisition begins at birth; however, the contribution of the mother on yeast transmission to the offspring and associated resistance is yet to be clarified. The aim of this study was to explore the vertical transmission of yeasts and their antifungal susceptibility profile in early life. Oral, fecal, and breastmilk samples were collected from 73 mother-child pairs four to twelve weeks after delivery and cultured on Sabouraud dextrose agar with chloramphenicol. The isolates were identified by MALDI-TOF MS. The vertical transmission was studied by microsatellite genotyping. Antifungal susceptibility was determined for fluconazole, voriconazole, miconazole, anidulafungin, and nystatin by broth microdilution assay, following CLSI-M60 guidelines. A total of 129 isolates were identified from 53% mother-child pairs. We verified the vertical transmission of Candida albicans (n = three mother-child pairs) and Candida parapsilosis (n = one mother-child pair) strains, including an antifungal resistant strain transmitted from breastmilk to the gut of a child. Most isolates were susceptible to the tested antifungals, with the exception of four C. albicans isolates and one R. mucilaginosa isolate. The vertical transmission of yeasts happens in early life. This is the first work that demonstrated the role of the mother as a source of transmission of antifungal-resistant yeasts to the child.

Potential Pathogenic and Opportunistic Oral Bacteria in Early Life: The Role of Maternal Factors in a Portuguese Population.

In early life, maternal factors are of the utmost relevance for oral microbiome acquisition and maturation. Therefore, our study explored the impact of maternal factors, such as saliva and breastmilk colonization, cardiovascular risk factors (CRF), type of delivery, oral health, and caregiving habits on the prevalence of potential pathogenic and opportunistic oral bacteria in early life. A total of 26 healthy mothers, 23 mothers with CRF, and their 50 children were included and samples (child's oral swabs, mother's saliva, and breastmilk) were collected 4 to 12 weeks after delivery and inoculated in selective and differential media for detection of non-fastidious Gram-negative and Gram-positive bacteria to isolate potential pathogenic and opportunistic bacteria identified by MALDI-TOF MS (414 isolates). Within mother-child dyads, the same species were identified in 86% of the pairs and potential pathogenic microorganisms from the Staphylococcaceae and Enterobacteriaceae families were found to be statistically significantly concordant between mother-child samples, particularly in the healthy group. Staphylococcus saprophyticus and Stenotrophomonas maltophilia oral colonization in mother-child pairs were associated with the presence of CRF. Breastfeeding was related to the early life oral colonization of Staphylococcus epidermidis in children from healthy mothers and C-section was associated with higher diversity of pathogens, independent of cardiovascular status (p = 0.05). This study reveals the presence of potential oral opportunistic and pathogenic bacteria in early life and highlights the importance of maternal factors in its acquisition.

Knowledge, attitudes, and practices of prenatal care practitioners regarding oral health in pregnancy-A systematic review.

BACKGROUND: Hormonal and behavioral changes during pregnancy may impact the oral health of women, which can influence the pregnancy course. Prenatal care practitioners (PCP) must be aware of this bidirectional relation in order to include an oral assessment in routine prenatal care. OBJECTIVES: To characterize the knowledge and attitudes of PCP regarding oral health in pregnant women. SEARCH STRATEGY: The search was carried out in PubMed, Web of Science, Lilacs, Scopus, and Embase on May 2022. SELECTION CRITERIA: Peer-reviewed cross-sectional studies published in English within the last 5 years that assessed the knowledge, attitudes, and practices of PCP towards oral health in pregnancy were selected. DATA COLLECTION AND ANALYSIS: Data were standardly extracted by the three reviewers from the selected articles and their bias was assessed. MAIN RESULTS: From a total of 996 articles, 24 were selected. Overall, most PCP have an adequate level of knowledge regarding the importance of oral health during pregnancy. Although several professionals reported referring their patients to a dentist, the attitudes and practices of the majority of PCP were still inadequate. CONCLUSIONS: PCP are aware of the importance of oral health during pregnancy but still lack translating this knowledge into clinical practice.

Embodiment Comfort Levels During Motor Imagery Training Combined With Immersive Virtual Reality in a Spinal Cord Injury Patient.

Brain-machine interfaces combining visual, auditory, and tactile feedback have been previously used to generate embodiment experiences during spinal cord injury (SCI) rehabilitation. It is not known if adding temperature to these modalities can result in discomfort with embodiment experiences. Here, comfort levels with the embodiment experiences were investigated in an intervention that required a chronic pain SCI patient to generate lower limb motor imagery commands in an immersive environment combining visual (virtual reality -VR), auditory, tactile, and thermal feedback. Assessments were made pre-/ post-, throughout the intervention (Weeks 0-5), and at 7 weeks follow up. Overall, high levels of embodiment in the adapted three-domain scale of embodiment were found throughout the sessions. No significant adverse effects of VR were reported. Although sessions induced only a modest reduction in pain levels, an overall reduction occurred in all pain scales (Faces, Intensity, and Verbal) at follow up. A high degree of comfort in the comfort scale for the thermal-tactile sleeve, in both the thermal and tactile feedback components of the sleeve was reported. This study supports the feasibility of combining multimodal stimulation involving visual (VR), auditory, tactile, and thermal feedback to generate embodiment experiences in neurorehabilitation programs.

Effect of uremic state in intestine through a co-culture in vitro intestinal epithelial model.

The progressive loss of renal function in chronic kidney disease (CKD) leads to the accumulation of uremic toxins. Recent studies related uremic plasma as well dysbiotic gut microbiome to impaired intestinal barrier function, allowing the translocation of microorganisms or by-products from the intestinal lumen to systemic circulation, contributing to systemic inflammation, cardiovascular risk and progression of CKD. Our main goal was to evaluate the impact of different uremic conditions on an improved in vitro intestinal Caco-2/HT29-MTX/Raji B triple co-culture model. For that, the impact of CKD patients' plasma and elevated urea concentration and its by-products on the triple model was assessed. The results showed that uremic conditions did not potentiate the Escherichia coli (E. coli) translocation, although may interfere with the integrity and the permeability of the intestinal barrier. Also, results showed that E. coli translocation was higher in Caco-2 monoculture than in Caco-2/HT29-MTX/Raji B triple model, suggesting that the triple model creates a more effective intestinal barrier. This study allowed to conclude that the uremic state influences the integrity of the intestinal barrier, but this influence could not be directly translated in an increase on the E. coli translocation through the intestinal epithelium, at least in Caco-2/HT29-MTX/Raji B intestinal epithelial barrier model.

Influence of delivery and feeding mode in oral fungi colonization - a systematic review.

Postnatal acquisition of microorganisms from maternal and environmental sources contributes to the child microbiome development. Several studies showed that the mode of delivery and breastfeeding may have impact on the oral bacterial colonization, however, the influence on oral fungal colonization is still unknown. We performed a systematic literature review on mother to child oral fungi transmission, namely regarding the association between the mode of delivery and breastfeeding in oral yeast colonization. Our analysis revealed no significant differences between the oral mycobiome of breastfed and bottle-fed children. As for the delivery mode, the majority of studies found a relation between fungal colonization and vaginal delivery. Candida albicans was the most commonly isolated fungi species. Our analysis suggests that maternal breastfeeding does not seem to influence oral mycology, but vaginal delivery appears to promote oral yeast colonization in early life.

A simple and effective method for addition silicone impression disinfection.

PURPOSE: Although dental impression disinfection is determinant to reduce the cross-infection risk, some studies have shown that, in real practice, the disinfection procedures vary considerably. Thus, the aim of this study was to evaluate the antimicrobial effectiveness and the impact on the dimensional stability of addition silicone' impressions of water wash and the most clinically used disinfection solutions: 3% hydrogen peroxide, commercial disinfectant MD520 (Durr) and 1% and 5.25% sodium hypochlorite. MATERIALS AND METHODS: For this investigation, dental impressions were taken on 16 volunteer dental students. The antimicrobial effectiveness of each procedure was evaluated by pour plate method. The dimensional stability was evaluated using a standardized stainless-steel model, according to ANSI/ADA nº19 specification. RESULTS: The study results showed that water wash does not alter the dimensional stability of addition silicone impressions but doesn't reduce the microbial load of the material (P>.05). On the other hand, addition silicone disinfection by immersion with 3% hydrogen peroxide, MD520 (Durr), or sodium hypochlorite at 1% and 5.25% does not alter the dimensional stability significantly but reduces > 99.9% of the microbial load of the impressions (P<.001). CONCLUSION: Addition silicone impressions should always be disinfected after water wash in order to reduce effectively the cross-infection risk. All disinfectants tested showed high antimicrobial efficiency without significant changes in three-dimensional shape of impressions. Hydrogen peroxide and sodium hypochlorite are of particular importance because are easily accessible in dental setting. The less explored hydrogen peroxide could be a valuable alternative for silicone impressions disinfection.

Unmet needs in Primary Care of older clients with mental health concerns.

OBJECTIVE: To examine the unmet needs of older clients with perceived mental health problems who attend primary healthcare services. DESIGN: Unmet needs were derived from (i) the health concerns and caregiver network availability provided by a General Practitioner (GPs) and from (ii) a qualitative analysis of an open question about needs completed by informal caregivers (ICs) of those clients. PARTICIPANTS: The sample comprised 436 clients with mean age of 75.2 years and 110 ICs with mean age of 56.7 years. SETTING: Primary healthcare centers in the North of Portugal. MAIN OUTCOME MEASURE: The Community Assessment of Risk Instrument-CARI (Clarnette RM, Ryan JP, O'Herlihy E, et al. The community assessment of risk instrument: investigation of inter-rater reliability of an instrument measuring risk of adverse outcomes. J Frailty Aging 2015;4: 80-9; O'Caoimh R, Healy E, Connell EO, et al. The Community Assessment of Risk Tool (CART): investigation of inter-rater reliability for a new instrument measuring risk of adverse outcomes in community dwelling older adults. Irish J Med Sci 2012.) and qualitative data about needs. RESULTS: Several needs were observed in relation to (1) mental state (e.g. cognition, anxiety/depression); (2) functionality (e.g. IADLS, bathing, mobility); (3) medical state (e.g. chronic diseases, vision deficits) and (4) IC ability to meet clients' needs. From the categorical analysis of the ICs' answers, an amount of unmet needs not only health related but also related with referrals and legal issues were found. CONCLUSIONS: This study shows a large number of unmet needs of older people. The evaluation of the clients combined with the evaluation of the testimonials of ICs enables the understanding of difficulties of both clients and caregivers, and which needs should be prioritized.

Screening of Dementia in Portuguese Primary Care: Methodology, Assessment Tools, and Main Results.

The objectives of this article are as follows: (1) to describe the assessment protocol used to outline people with probable dementia in Primary Health Care; (2) to show the methodological design and procedure to obtain a representative sample of patients with probable dementia; and (3) to report the main characteristics of the sample collected in the context of the study "Characteristics and needs of people with probable dementia." The study protocol was based on the "Community Assessment of Risk and Treatment Strategies (CARTS) Program" and is composed by a set of instruments that allow the assessment of older adults with probable dementia in several areas (health, psychological, functionality, and other). Descriptive analysis was used to characterize the final sample (n = 436). The study protocol as well as the methodological procedure to obtain the referral of research participants and data collection on the condition of people with probable dementia in Primary Health Care proved to be a valuable tool to obtain a sample of patients distributed by the full range of probable dementia in a large geographical area. Results may allocate the design of care pathways for old people with cognitive disorders to prevent, delay impairment, and/or optimize quality of life of patients.
