Abstract Background To examine the effects of a 6-month multicomponent (MT) exercise intervention in the functional capacity and ability to independently perform activities of daily living (ADL) of individuals diagnosed with neurocognitive disorder (NCD). Methods A quasi-experimental controlled trial with a parallel design study was conducted in multicentered community-based settings. Forty-three individuals (N Female: 30) were allocated to an exercise group (EG; N: 23; mean 75.09, SD = 5.54 years) or a control group (CG; N:20; mean 81.90, SD = 1.33 years). The EG engaged in a 6-month MT program (60-min sessions, twice a week). Exercise sessions were divided into a warm-up, specific training (e.g., coordination and balance, lower and upper body strength, and aerobics), and cool down. Lower body function, mobility, and gait speed were evaluated through Short Physical Performance Battery (SPPB), Timed-Up and Go test (TUG) and 6-Meter Walk test, respectively. The Barthel Index (BI) was administered to assess individuals’ ADL independence. Evaluations were performed before and after the 6-month intervention. Results Linear Mixed Models revealed a statistically significant interaction (time X group) effect factor on SPPB (B = 2.33, 95% CI: 1.39–3.28, p

Informal caregivers of people with neurocognitive disorders (NCDs) may play a decisive role in guaranteeing partners’ participation in community-based physical exercise interventions. However, little is still known about their perspective on being involved in such programs that are specifically designed for their partners. This study aimed to explore the views of caregivers of people with NCDs about taking part in a multicomponent physical exercise intervention with their partners and to explore the perceived impact of this program on those caregivers who enrolled in it. An exploratory qualitative study was conducted with 20 caregivers (67.5 ± 13.94 years; seven female) from the “Body & Brain” project. Ten took part in the physical exercise sessions (active-participating caregivers), and the others did not (social-participating caregivers). Data retrieved from semi-structured interviews were analyzed following a thematic analysis approach. Regardless of their participation level, all caregivers reported their inclusion to be important in enhancing their partners’ initiation and engagement in the sessions; also, they all identified personal gains. Active-participating caregivers reported exercise-related benefits on general health, enjoyment, and social connectedness. Social-participating caregivers considered this intervention an opportunity for respite and appreciated being involved only occasionally (i.e., occasional gatherings or telephone contacts). The findings support the inclusion of caregivers in physical exercise interventions designed for partners with NCDs, considering their decisive role in the partners’ adherence and engagement and due to the perceived gains. Future community-based interventions designed for people with NCDs should consider giving caregivers the opportunity to choose whether they want or not to be actively involved in the exercise sessions. Further studies with larger samples are needed to verify these results, comparing caregivers’ point of view at baseline and post-intervention.

Abstract Background Dementia is a leading cause of death and disability that was declared as one of the greatest health and social care challenges of the twenty-first century. Regular physical activity and exercise have been proposed as a non-pharmacological strategy in disease prevention and management. Multicomponent Training (MT) combines aerobic, strength, balance and postural exercises and might be an effective training to improve both functional capacity and cognitive function in individuals with dementia (IwD). Nevertheless, data on the effects of MT in IwD are still limited and the extent to which IwD can retain improvements after an exercise intervention still needs to be elucidated. The aim of “Body & Brain” study is to investigate the effects of a 6-month MT intervention and 3-month detraining on the physical and cognitive function of IwD. Additionally, we aim to explore the impact of this intervention on psychosocial factors and physiologic markers related to dementia. Methods This study is a quasi-experimental controlled trial using a parallel-group design. The study sample consists of community-dwelling individuals aged ≥60 years who are clinically diagnosed with dementia or major neurocognitive disorder. Participants will be either allocated into the intervention group or the control group. The intervention group will participate in MT biweekly exercise sessions, whereas the control group will receive monthly sessions regarding physical activity and health-related topics for 6 months. The main outcomes will be physical function as measured by the Short Physical Performance Battery (SPPB) and cognitive function evaluated using the Alzheimer Disease Assessment Scale – Cognitive (ADAS-Cog) at baseline, after 6-months and 3-months after the end of intervention. Secondary outcomes will be body composition, physical fitness, daily functionality, quality of life, neuropsychiatric symptoms and caregiver’s burden. Cardiovascular, inflammatory and neurotrophic blood-based biomarkers, and arterial stiffness will also be evaluated in subsamples. Discussion If our hypothesis is correct, this project will provide evidence regarding the efficacy of MT training in improving physical and cognitive function and give insights about its impact on novel molecular biomarkers related to dementia. This project may also contribute to provide guidelines on exercise prescription for IwD.

Abstract Background People with visual impairment have benefitted from recent developments of assistive technology that aim to decrease socio-economic inequality. However, access to post-secondary education is still extremelly challenging, especially for scientific areas. The under representation of people with visual impairment in the evolution research community is connected with the vision-based communication of evolutionary biology knowledge and the accompanying lack of multisensory alternatives for learning. Results Here, we describe the development of an inclusive outreach activity based on a multisensory phylogeny representing 20 taxonomic groups. We provide a tool kit of materials and ideas that allow both the replication of this activity and the adaptation of others, to include people with visual impairment. Furthermore, we provide activity evaluation data, a discussion of the lessons learned and an inclusive description of all figures and visual data presented. The presented baseline data show that people with visual impairment indeed have lack of access to education but are interested in and apt to understand evolutionary biology concepts and predict evolutionary change when education is inclusive. Conclusions We show that, with creative investment, basic evolutionary knowledge is perfectly possible to be transmitted through multisensory activities, which everyone can benefit from. Ultimately, we hope this case study will provide a baseline for future initiatives and a more inclusive outreach community.

AimThe aim of our study was to analyze physical activity levels, sitting time, physical fitness, and their relationship with depressive symptoms after home confinement in previously active older adults.MethodsThis cross-sectional study sample comprised 68 older adults (74.24 ± 5.67 years) from a community-based exercise program conducted in Porto, Portugal. After home confinement, participants were assessed in person for lower-body strength (30-s chair stand test), cardiorespiratory fitness (6-min walking test), agility/dynamic balance (8-ft up-and-go test), handgrip strength, and anthropometry. Telephone interviews were performed to evaluate depressive symptoms with the Geriatric Depression Scale – 15 items (GDS-15) and physical activity levels through the International Physical Activity Questionnaire (IPAQ-SV). Individuals were also asked to self-report changes in their physical activity levels and time spent sitting.ResultsNinety percent of older adults self-reported a decrease in overall physical activity levels, and nearly 65% increased daily sitting time during the home confinement. However, previously active older adults still presented high levels of physical fitness (scores above 50th compared with Portuguese normative values) after 11 weeks of home confinement. Overall, 52.9% of participants scored 5 or more points on GDS-15, which is suggestive of depression. Higher levels of moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness were found in the non-depressed group compared with the depressed group. Finally, results from multiple regression analysis revealed that MVPA was negatively associated with depression. This model explained 16.4% of the variability seen in depression score, controlled for age, gender, and education.ConclusionEven reporting a decline in physical activity, older adults who previously participated in a formal exercise program, still presented high levels of physical fitness after 11 weeks of home confinement. However, MVPA, but not physical fitness, seems to be an associated depression score in previously active older adults. These results reinforce the importance of older adults to remain physically active, since higher levels of MVPA may have a protective effect on depressive symptoms and, therefore, mitigate the negative impact of home confinement on mental health. Future longitudinal research studies are needed to ascertain these results.

The reintroduction of livestock grazing to regulate biomass load is being tested for large-scale restoration in Mediterranean landscapes affected by rural abandonment. Concurrently, there is a need to develop cost-effective methods to monitor such interventions. Here, we investigate if satellite data can be used to monitor the response of vegetation phenology and productivity to grazing disturbance in a heterogenous forest mosaic with herbaceous, shrub, and tree cover. We identify which vegetation seasonal metrics respond most to grazing disturbances and are relevant to monitoring efforts. The study follows a BACI (Before-After-Control-Impact) design applied to a grazing intervention in a Pyrenean oak forest (Quercus pyrenaica) in central Portugal. Using NDVI time-series from Sentinel-2 imagery for the period between June 2016 and June 2021, we observed that each type of vegetation exhibited a distinct phenology curve. Herbaceous vegetation was the most responsive to moderate grazing disturbances with respect to changes in phenology and productivity metrics, namely an anticipation of seasonal events. Results for shrubs and trees suggest a decline in peak productivity in grazed areas but no changes in phenology patterns. The techniques demonstrated in this study are relevant to a broad range of use cases in the large-scale monitoring of fine-grained heterogeneous landscapes.

Background: To investigate physical fitness as a mediator of the relationship between arterial stiffness and cognitive function in seniors. Methods: This is a cross-sectional study comprising 155 individuals free from chronic diseases (75.5 ± 6.5 years; 69.7% female). Carotid-femoral pulse wave was assessed through applanation tonometry. Cognitive function was evaluated with Montreal Cognitive Assessment (MoCA). Physical fitness was assessed through handgrip strength and Senior Fitness Test (SFT). A Z-score including individual physical fitness components was computed as a global index of physical fitness. Hayes’s PROCESS macro for Statistical Package for the Social Sciences was used for the simple mediation analysis, using bootstrapped procedures. Results: After adjustments for sex and age, physical fitness Z-score mediated the relationship between arterial stiffness and cognitive function [Indirect effect = −0.382 (95% CI −0.670 to −0.138)]. Conclusion: Findings suggest that physical fitness, independently of sex and age, is a mediator on the relationship between arterial stiffness and cognitive function in seniors free from chronic diseases.

Eucalyptus, with the commercial name of Blue gum, is a viscoelastic material strongly influenced when under constant load (Creep), being this phenomenon - in the context of displacements - exacerbated with transient relative humidity (variations of the water content in the wood material). The evaluation of bending creep was done in indoor / constant and transient humidity conditions. In the latter, mechano-sorptive effect, the creep bending tests were done for a period of 60 days with cycles of wetting-and-drying. Each cycle has 7 days of duration. Defect free specimens with dimensions of 20*20*400 mm3 (approximately to the scale 1:10) of Eucalyptus globulu. wood species were used. To fit the creep behaviour and extrapolate results for different periods (1, 10 and 50 years) a survey of different numerical models was done. Rational, parabolic and polynomial functions were chosen. In bending, Blue gum wood species presented a behaviour without a creep limit, therefore labile. Through the models used for extrapolations a significant variability was found for different periods. Values of the main standard of wood design (Eurocode 5) were exceeded. The most consistent mathematical model was the rational model because it is the one that has led to closer and stable results.

This paper describes an energy harvesting system composed of an organic photovoltaic cell (OPV) connected to a DC–DC converter, designed in a 130 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology, with a quasi- maximum power point tracking (MPPT) algorithm to maximize the system efficiency, for indoor applications. OPVs are an emerging technology with potential for low cost indoor light energy harvesting. The OPV current-voltage curves (I-V) under an irradiance of solar simulator Oriel Sol 3A, at room temperature, are obtained and an accurate electrical model is derived. The energy harvesting system is subjected to four different indoor light sources: 35 W halogen, 3.5 W LED, 5 W LED, and 7 W LED, positioned at three different heights (0.45 m, 0.26 m, and 0.11 m), to evaluate the potential of the system for indoor applications. The measurements showed maximum efficiencies of 60% for 35 W halogen and 45% for 7 W LED at the highest distance (0.45 m) and between 60% (5 W LED) and 70% (35 W halogen), at the shorter distance (0.11 m). Under irradiation, the integrated CMOS circuit presented a maximum efficiency of 75.76%, which is, to the best of the authors’ knowledge, the best reported power management unit (PMU) energy system using organic photovoltaic cells.

La educación ambiental se fundamenta en tres áreas interrelacionadas entre sí que favorecen el desarrollo personal y social: construcción de identidades, desarrollo de la interacción humana y relación con los otros no humanos y con el ambiente físico. El propósito de esta experiencia es construir e implementar, en equipo, un proceso de educación ambiental básico para promover en los participantes la conciencia de una problemática ambiental y del posible papel de cada uno en la superación de la misma. El proceso de cátedra ambiental dentro de la Facultad de Ciencias del Deporte, U.D.C.A., desarrolla cinco fases: 1. Aproximación conceptual donde se aborda una problemática ambiental y sus implicaciones vitales, y se identifica una institución que trabaje en el área que apoye el proceso. 2. Itinerarios ambientales donde se reconocen en la realidad de las problemáticas ambientales. 3. Construcciones correspondientes al diseño de actividades deportivas y recreativas adaptadas específicamente a las necesidades ambientales del contexto. 4. Desarrollo e implementación para promover la conciencia ambiental. 5. Retroalimentación consistente en la evaluación del proceso. Así, se han desarrollado cuatro proyectos de educación ambiental.

This study deals with the role of hardness and chemical toxicity in the resistance of pinewood to marine borers. Portuguese wood Maritime pine (Pinus pinaster) was modified with 1,3-dimethylol 4,5-dihydroxy ethylene urea (DMDHEU), methylated methylol melamine (MMF), tetraethoxysilane (TEOS) and two types of wax. In addition, for comparative purposes, different control species, Ipê, Beech and Blue Gum and CCA treated pine were included. All specimens were exposed over 2 years in sea (Porto, north of Portugal). Three inspections were performed after exposure (6, 12 and 24 months). The influence of type and level of modification as well as hardness was evaluated. As results: Specimens modified with resin have shown slight or trace attack by Teredinids in DMDHEU with low level of modification (10% of weight percent gain, WPG); MMF resin with high and low level of modification (25% and 10% of WPG) have shown trace to moderate attack, respectively. With the TEOS and wax impregnated wood which fill the cell lumens no significant difference in marine borers attack was found as compared to unmodified control specimens, despite the increased hardness.

Orthopedic traumas are common, costly, and burdensome - particularly for patients who transition from acute to chronic pain. Psychosocial factors, such as pain catastrophizing and pain anxiety, increase risk for poor outcomes after injury. The Toolkit for Optimal Recovery (TOR) is a novel multi-component mind-body intervention informed by the fear-avoidance model to promote re-engagement in daily activities and prevent transition toward chronic pain and physical dysfunction. The current case series aims to 1) describe the intervention and 2) showcase the treatment course of three TOR completers from diverse geographic locations in the U.S. with distinct injury types and varying personal identities to illustrate how the intervention can be delivered flexibly. Results indicate pre-to-post program improvement in physical function, pain severity, pain catastrophizing, pain anxiety, and other relevant outcomes targeted by the intervention (i.e., depression, mindfulness, coping). Experiences of our three TOR completers suggest that integrating TOR with standard orthopedic care may promote physical recovery after injury., (© 2023.

Introduction: Approximately 50% of persons with orthopedic injuries experience psychosocial distress (e.g., depression, anxiety), which can predict chronic pain and disability. Offering psychosocial services in orthopedic settings can promote patient recovery. This study explores health care professionals' perceptions of and recommendations regarding integrated psychosocial care for orthopedic settings., Methods: We conducted 18 semi-structured focus groups with 79 orthopedic health care professionals (e.g., surgeons, residents, nurses) across three Level I Trauma Centers. This secondary data analysis used the evidence-based Rainbow Model of Integrated Care framework to structure hybrid inductive-deductive qualitative data analysis., Results: Orthopedic health care professionals identified potential benefits to psychosocial service integration across all dimensions of integration (i.e., clinical, professional, organizational, system, functional, and normative). These benefits included increased patient satisfaction with care, decreased burden on medical providers to manage patient distress, and decreased healthcare utilization costs. They also identified barriers (e.g., fast-paced clinic flow, mental health stigma) and offered recommendations to address barriers across dimensions of integration., Conclusion: Integrated psychosocial care for orthopedic trauma patients has the potential to improve patient recovery and long-term physical and mental health outcomes. This work identifies strategies to inform the development and implementation of initiatives to integrate psychosocial services within orthopedic settings., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2023 The Author(s).)

Objective: Substance use is the leading cause of preventable deaths in the U.S. Chronic pain is associated with risky substance use. Black individuals experience substantial disparities in pain and substance use outcomes and treatment. Maladaptive psychological reactions to chronic pain, such as pain catastrophizing and pain anxiety, can increase substance use among White individuals. However, no research to date has tested this among Black individuals. This study is the first to test the relationships between pain catastrophizing, pain anxiety, and substance use among Black individuals with chronic pain who use opioid medications., Method: Black adults with chronic pain who use opioids ( N = 401) completed online measures of pain catastrophizing (Brief Pain Catastrophizing Scale); pain anxiety (Pain Anxiety Symptom Scale Short Form-20); risky use of alcohol, tobacco, e-cigarettes, cannabis and opioids (Alcohol, Smoking and Substance Involvement Screening Test); and opioid dependence (Severity of Dependence Scale). We conducted zero-inflated and hierarchical regressions to test associations between pain catastrophizing, pain anxiety and substance use (risky use; general use vs. nonuse) above that of demographics, pain intensity and pain interference., Results: Pain catastrophizing was uniquely associated with risky use of all substances (βs = .03-.09, p s < .001-.02), opioid dependence (β = .13, SE = .05, p = .01), and use (vs. nonuse) of tobacco, alcohol and opioids (βs = .07-.11, p s < .001-.02). Pain anxiety was uniquely associated with tobacco use (vs. nonuse; β = -.02, SE = .01, p = .04) and severity of opioid dependence (β = .21, SE = .01, p < .001)., Conclusion: Pain catastrophizing and, to a lesser degree, pain anxiety may be useful intervention targets for this underserved and understudied population. Addressing them may help reduce additional health complications and costs associated with substance use-related risk and dependence. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Background: Chronic pain and problematic substance use are commonly co-occurring and highly detrimental issues that are especially prevalent in U.S. veteran populations. Although COVID-19 made clinical management of these conditions potentially difficult, some research suggests that certain veterans with these conditions did not experience this period as negatively as others. It is thus important to consider whether resilience factors, such as the increasingly-studied process of psychological flexibility, might have led to better outcomes for veterans managing pain and problematic substance use during this time of global crisis., Methods: This planned sub-analysis of a larger cross-sectional, anonymous, and nationally-distributed survey ( N  = 409) was collected during the first year of the COVID-19 pandemic. Veteran participants completed a short screener and battery of online surveys assessing pain severity and interference, substance use, psychological flexibility, mental health functioning, and pandemic-related quality of life., Results: For veterans with chronic pain and problematic substance use, the pandemic resulted in a significant lowering of their quality of life related to meeting basic needs, emotional health, and physical health compared to veterans with problematic substance use but no chronic pain diagnosis. However, moderation analyses revealed that veterans with these comorbid conditions experienced less negative impacts from the pandemic on quality of life and mental health when they reported greater psychological flexibility. For veterans with problematic substance use only, psychological flexibility was also related to better mental health functioning, but did not significantly correlate with their quality of life., Conclusion: Results highlight how COVID-19 differentially impacted veterans with both problematic substance use and chronic pain, such that this group reported particularly negative impacts of the pandemic on multiple areas of quality of life. However, our findings further emphasize that psychological flexibility, a modifiable resiliency process, also buffered against some of the negative impacts of the pandemic on mental health and quality of life. Given this, future research into the impact of natural crises and healthcare management should investigate how psychological flexibility can be targeted to help increase resiliency for veterans with chronic pain and problematic substance use., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Reilly, Wolkowicz, Heapy, Ross MacLean, Duarte, Chamberlin, Harris, Shirk and Kelly.)

Introduction: The COVID-19 pandemic generated concerns about rising stress and alcohol use, especially in U.S. veterans who experience high rates of anxiety disorders (ADs), alcohol use disorder (AUD), and dual AD+AUD diagnoses. This study investigated differences among these diagnostic groups in a veteran population related to their concern about COVID-19, impacts of COVID-19 on quality of life, and self-reported changes to urge to drink and drinking frequency., Methods: A nationally administered online survey was given to a sample of U.S. veterans reporting substance use issues during the pandemic. Differences in the level of concern about COVID-19, impacts of COVID-19 on quality of life, and drinking behaviors were examined in those self-reporting AD ( n = 98), AUD ( n = 46), or AD+AUD ( n = 67). Consensual qualitative research was used to analyze an open-ended question about COVID-19's impact on substance use, health, and quality of life., Results: Veterans with AD+AUD experienced significant increases in urge to drink and alcohol consumption compared to veterans with AD only. Greater urge and frequency of drinking were associated with greater negative impacts of COVID-19 on quality of life. There were no differences among groups in global negative impact on quality of life or level of COVID-19 concern. However, respondents described specific COVID-19 worries, with qualitative findings revealing that those with AD+AUD reported a disproportionate psychosocial burden due to the pandemic., Discussion: Special attention in screening and treatment should be given to those with a dual AD+AUD diagnosis who may be experiencing both an increase in alcohol use and psychosocial burden as stress increases due to the pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Duarte, Kelly, Shirk, Chamberlin and Reilly.)

Background: F abry disease (FD) is an X-linked lysosomal storage disorder with accumulation of globotriosylceramide, causing neurologic involvement mainly as acroparesthesias and cerebrovascular disease. Aseptic meningitis has been reported in 11 patients with FD, but no prior study has correlated alpha-galactosidase (GLA) specific variants with meningitis. We present in this manuscript a family in which a novel GLA pathogenic variant was associated with aseptic meningitis in 2 of 5 family members., Methods: This study began with identifying the proband, then screening family members for FD symptoms and evaluating symptomatic individuals for genetic and biochemical status. All patients underwent magnetic resonance imaging, and those with headache underwent cerebrospinal fluid (CSF) analysis., Results: Five patients (3 females) from a single family were included in this study. Mean age at diagnosis was 20.6 years. Two patients (40%) had aseptic meningitis; one of them also had cerebrovascular events. C-reactive protein and erythrocyte sedimentation rate were elevated during aseptic meningitis episodes. Both patients responded to intravenous methylprednisolone with resolution of fever, headache, and vomiting. One of them recurred and needed chronic immunosuppression with azathioprine., Conclusion: We described aseptic meningitis in a family with a novel GLA variant. Meningitis might be a common phenomenon in FD and not a particularity of this variant. Understanding the mechanisms underlying meningitis and its association with cerebrovascular events may lead to a new paradigm of treatment for stroke in these patients. Further prospective studies with CSF collection in patients with FD and recurrent headache could help to elucidate this question., (© 2022. Fondazione Società Italiana di Neurologia.)

Introduction: Patients admitted to the Neuroscience Intensive Care Unit (Neuro-ICU) with acute neurological illnesses (ANI; e.g., stroke, tumor, TBI) and their informal caregivers experience high rates of anxiety, depression, and posttraumatic stress. To address this need, we previously developed the Recovering Together (RT) dyadic intervention to help prevent chronic emotional distress in both patients and caregivers. Currently, we are conducting a fully-powered, single-blind randomized clinical trial (RCT) to evaluate the efficacy of RT versus an attention matched health education control. Here, we describe the protocol and current status of this RCT., Methods: We aim to recruit 194 at risk patient-caregiver dyads from the Neuro-ICU at MGH. Eligible dyads include patients diagnosed with ANI, cognitively intact, at least one partner endorses emotional distress (on Hospital Anxiety and Depression Scale), English speaking, age 18 or older. Dyads are randomized to the intervention (RT-1) or control condition (RT-2) (both six sessions). RT-1 teaches resiliency (e.g., coping, mindfulness) and interpersonal skills. RT-2 provides education on health-related topics (e.g., stress, self-care, adhering to medical recommendations). Blinded research assistants collect measures at baseline, post-intervention, and three months follow-up. We will conduct mixed linear, mediation, and actor-partner interdependence models to examine changes in dyads' outcomes across time., Results: We have recruited 41 dyads and aim to recruit 194 total., Discussion: If successful, we plan to test RT in a large-scale, multisite hybrid effectiveness-implementation study in Neuro-ICUs across the country. Enhancing psychosocial supports for patients and families could improve health outcomes, healthcare efficiency, and the culture of these units., Competing Interests: Declaration of Competing Interest We declare no relevant conflicts of interest., (Copyright © 2022.

As the COVID-19 pandemic sweeps the globe, many veterans with substance use issues have faced the closure of treatment facilities, mandates to shelter in place, and social distancing measures. To better understand their pandemic experiences, substance use changes, and functioning, a survey was nationally administered to a sample of United States veterans reporting substance use issues during the pandemic. The purpose of this cross-sectional online survey for veterans ( N  = 409) was to report on COVID-19 experiences, safety behaviors, and infection experiences while also investigating the relationship among addictive behaviors, mental and physical health, and COVID-19 impact. Measures also assessed specific substance use concerns, pandemic-related loneliness, and functioning. Though few veterans reported personally receiving a confirmed COVID-19 medical diagnosis (10.5%), the impact of pandemic stressors was evident, with a majority reporting anxiety related to contracting COVID-19 (61.4%) or fear of a family member or close friend contracting COVID-19 (58.7%). Participants reported increased use of alcohol (45.3%), sedatives (36.6%), inhalants (35.7%), tobacco (35.0%), and cannabis (34.9%), attributed specifically to the pandemic. Regression analyses revealed that even when controlling for the contribution of problematic substance use issues, negative pandemic impacts and self-reported COVID-19 related loneliness were related to more impaired physical and mental health functioning during the pandemic. Findings from this sample of veterans with addiction issues add to the growing literature suggesting unique and adverse effects of COVID-19 stressors on functioning while also revealing specific pandemic impacts for this group., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Reilly, Chamberlin, Duarte, Harris, Shirk and Kelly.)

The COVID-19 (SARS-CoV-2) infection started in China, Wuhan City, Hubei Province, in December 2019, and it was declared a pandemic in mid-March 2020, caused by a new coronavirus strain called SARS-CoV-2. The pathogenesis of kidney injury attributed to SARS- CoV-2 is not well defined yet. Observations show that the kidney damage caused by the new virus mutation is mainly tubular, with impairment of glomerular filtration and high levels of urea and creatinine. A study with seriously ill patients with COVID-19 showed that acute kidney injury was present in 29%. In the face of this evidence, based on recent studies, we can see the great renal contribution as an impact factor in the evolution of COVID-19, not just as a complicator of severity, but maybe part of the initial cascade of the process, requiring a deeper analysis using conventional biomarkers of kidney injury and more aggressive clinical intervention in patients at risk, in an attempt to reduce mortality.

Biogenic amines are low molecular weight organic bases with biological activity, produced by the action of the decarboxylase enzyme. Microorganisms used in food fermentation are able to produce them. Consumption of these compounds causes serious toxicological effects, which are undesirable for human health. Although there is no specific legislation regarding the amine content in food and beverages, the presence and accumulation of amines is a matter of great importance. The aim of this review is to highlight the need for further studies and foment debate about the presence of biogenic amines in a variety of foods.
