Solitude in old age: a scoping review of conceptualisations, associated factors and impacts.

OBJECTIVE: This study aimed to map the existing scientific research about solitude in older adults, focusing on its conceptualizations, associated factors, and impacts. METHOD: A scoping review was conducted, searching Scopus, Web of Science, PubMed, and Academic Search Complete databases for publications from 1985 until December 2023. RESULTS: Twenty-four studies were included. The main findings suggest a wide-ranging conceptualisation of solitude, with most studies (n = 16) adopting neutral definitions such as "being alone, without communicating with others"; and a subset of studies adopting definitions that alluded to "positive solitude" (as the choice of being with oneself, underscoring potential benefits). Individual characteristics were identified as key associated factors of solitude. Both positive impacts and negative impacts were reported. CONCLUSION: The variability in conceptualisation and impacts likely stems from methodological and theoretical differences in approaching solitude. This underscores the need for additional research to establish a widely accepted conceptual framework. Such consensus could enhance the understanding of the conditions contributing to positive and negative impacts associated with solitude and inform targeted interventions.

Illness perception and treatment adherence in haemodialysis: a systematic review.

Patients with kidney failure need lifelong renal replacement therapy to survive and, worldwide, in-centre haemodialysis is the most common modality. The efficacy of this treatment largely depends on the patients' adherence to several health behaviours. According to Leventhal's self-regulation model, patients' illness perceptions can be a key factor for treatment adherence. Therefore, it is of utmost importance to better understand this relationship to further fine-tune the effectiveness of renal rehabilitation programs. This study aimed to systematically review the literature on the association between illness perceptions and treatment adherence in adults undergoing in-centre haemodialysis. The search was performed on PubMed, Scopus, CINAHL, Web of Science (all databases included), and ProQuest (all databases included), from the 17th to the 21st of December 2020. The last update was performed on the 9th of June of 2022. Articles were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklists for Analytical Cross-Sectional Studies. Nine studies were included comprising a total of 1161 patients undergoing in-centre haemodialysis. Associations between illness perceptions and treatment adherence were found in six studies. Adherence to dietary restrictions was the type of adherence with more significant associations with illness perceptions, followed by fluid control and medication intake. Two studies combining several types of adherences into an overall score also showed significant associations with illness perceptions. No significant associations were found between illness perceptions and adherence to dialysis sessions. These findings suggest that illness perceptions in patients undergoing in-centre haemodialysis should continue to receive research attention. Future interventions should acknowledge the importance of modifying maladaptive illness perceptions to improve treatment adherence in kidney failure. The protocol for this systematic review was registered on PROSPERO (CRD42021231929).

The clinical utility of the Distress Thermometer in non-oncological contexts: A scoping review.

AIMS: To assess the clinical utility of the Distress Thermometer (DT) in non-cancer populations. METHODS: The search was performed between the 6th and the 18th of April 2020, on the following databases: Web of Science (all databases included), Scopus and Science Direct. One last update was performed on 5 June 2020. The findings were reported using the PRISMA-ScR. RESULTS: Fifty-three studies were included. Overall results indicated that this tool has been used in several contexts and populations (clinical and non-clinical). The DT is highly accessible, suitable and relevant for health professionals and/or researchers who aim to use it as a distress screening tool, particularly in patients with chronic physical conditions. Assumptions about its practicality and acceptability in non-oncology care should be made with caution since few studies have explored the psychometric qualities of this instrument, the completers' perceptions about completing the DT and the perceptions of health professionals who administer the tool. CONCLUSIONS: This lack of information undermines conclusions about the overall clinical utility of the DT as a screening tool for distress in individuals who do not have cancer. IMPLICATIONS FOR PRACTICE: Future research should aim to fill this gap and investigate the psychometric qualities of the DT through validation studies and, thus, increase the rigour of its application and clinical utility in non-oncological contexts.

The response of nitrous oxide emissions to different operating conditions in activated sludge wastewater treatment plants in Southeastern Brazil.

The continuous measurements of N2O emissions from the aeration tanks of three activated sludge wastewater treatment plants (WWTPs) operated with biological nitrogen removal (BNR) and non-BNR were performed during the different operating conditions of several parameters, such as aeration, dissolved oxygen (DO) profiling and organic shock loading (with landfill leachate). The nitrification process is the main driving force behind N2O emission peaks. There are indications that the variation of the air flow rate influenced N2O emissions; high N2O emissions denote over-aeration conditions or incomplete nitrification, with accumulation of NO2- concentrations. Thus, continuous measurements of N2O emissions can provide information on aeration adequacy and the efficiency of complete nitrification, with major focus on DO control, in order to reduce N2O emissions. An additional concern is the observed propensity of WWTPs in developing countries to receive landfill leachates in their wastewater systems. This practice could have adverse effects on climate change, since wastewater treatment during periods of organic shock loading emitted significantly higher amounts of N2O than without organic shock loading. In short, non-BNR WWTPs are subject to high N2O emissions, in contrast to BNR WWTP with controlled nitrification and denitrification processes.

Indica rice cultivar IRGA 424, transformed with cry genes of B. thuringiensis, provided high resistance against Spodoptera frugiperda (Lepidoptera: Noctuidae).

Plant expression of the entomopathogenic bacteria Bacillus thuringiensis cry gene has reduced the damage created by insect pests in several economically important cultures. For this study, we have conducted genetic transformation of the indica rice "IRGA 424", via Agrobacterium tumefaciens, using the B. thuringiensis cry1Aa and cry1B genes, with the objective of obtaining rice plants resistant to the insect pests from this culture. The gene constructions harbor the promoters maize proteinase inhibitor and ubiquitin. The results showed that high concentration of the hormone 2,4-dichlorophenoxyacetic acid and agarose as the gelling agent helped the production of embryogenic calli for the analyzed cultivar. More than 80% of the obtained transformed plants revealed the integration, using polymerase chain reaction, of the cry1Aa and cry1B genes. Analysis of the expression of the heterologous protein by Western blotting revealed the expression of the Cry1B delta-endotoxin in IRGA 424 plants transformed with the ubiquitin promoter. Data showed the production and dissemination of a high number of embryogenic calli in addition to obtaining plants transformed with the cry1Aa and cry1B genes until the reproductive phase. The feed bioassays with the transformed plants and Spodoptera frugiperda (JE Smith) larvae indicated high rates of mortality to the insect target. The highest corrected mortality rate achieved under laboratory conditions with Bt-rice plants transformed with the cry1B and cry1Aa genes was 94 and 84%, respectively. Thus, our results demonstrated the great potential of transformed Bt-rice plants in controlling the damage caused by these insect pests in rice paddy fields.

Views on volunteering in mental health: a focus group study with mental health professionals and volunteers in Portugal.

INTRODUCTION: Volunteering has reported health benefits. However, little is known in Portugal about the views of mental health professionals and volunteers on volunteering in mental health care. METHODS: A qualitative secondary analysis of data from six focus groups with 28 participants was conducted in order to explore and compare the perspectives on volunteering in mental health of two stakeholders: mental health professionals and volunteers in Portugal. RESULTS: Four main themes arose: the nature of the volunteering relationship; volunteering has multiple aims; technology has potential for volunteering; and volunteering has its challenges. Although there were mostly commonalities between their views, some variability suggested that different stakeholders may consider different aspects of volunteering differently. Overall, stakeholders called for structured recruitment and support, training, defining boundaries and fighting the stigma of mental illness. CONCLUSION: Despite the lack of volunteering tradition in mental health care in Portugal, volunteering programmes were perceived as an important resource for patients with mental illness.

Risk Of Venous Thrombosis In The Primary Care Setting During The Covid-19 Pandemic.

AIMS: This study aimed to evaluate the variability of risk factors among patients with lower limb venous thrombosis, either Deep Vein Thrombosis (DVT) or Superficial Vein Thrombosis (SVT) in community patients with recent or current SARS-CoV-2 infection compared to a historical cohort. METHODS: We performed a historical retrospective analysis of all patients who presented to a primary health care unit and were diagnosed with DVT or SVT from January 2020 to December 2021. Historic controls were selected from January 2018 to December 2019. Demographic and clinical data were collected, including BMI, use of oral combined contraception, smoking status and date of COVID-19 infection diagnosis. Univariate analysis was performed for data assessment, including Chi-Square and ANOVA tests. RESULTS: Of the 8547 patients who attended a non-programmed consultation in the timeframe, seventy-nine patients (0.9%) were diagnosed with DVT (19) or SVT (60) and were included in the study. Their mean age was 57.3 ± 15.93 years, with a female-to-male ratio of 3.2 to 1. There was no significant association between COVID-19 and the development of DVT or SVT (p=0.151). However, there was a trend observed indicating a shift in the predominant gender in patients diagnosed with these conditions (85% females in 2018 versus 53.8% in 2021; p=0.077). CONCLUSIONS: Outpatients seen by general practitioners during the pandemic of COVID-19 appear to present a trend towards an increased risk of combined DVT and SVT compared with patients of a historical cohort. Further studies are necessary to shed some light on this issue since robust evidence enables clinicians and policymakers to minimize venous thromboembolism risk in patients with SARS-CoV-2 infection.

Environmental risk caused by drug waste in the city of Rio de Janeiro, Brazil, during the SARS-Cov19 pandemic. / Risco ambiental provocado por resíduos de medicamentos na cidade do Rio de Janeiro, Brasil, durante a pandemia por SARS-Cov19.

The relationship between the distribution of medicines used in the Pandemic by SARS-COV-19 in the municipality of Rio de Janeiro and the estimated level of environmental risk caused by their residues was evaluated. The amount of medicines distributed by primary health care (PHC) units between 2019 and 2021 were collected. The risk quotient (RQ) corresponded to the ratio between the estimated predictive environmental concentration (PECest) obtained by the consumption and excretion of each drug and its non-effective predictive concentration (PNEC). Between 2019 and 2020, the PECest of azithromycin (AZI) and ivermectin (IVE) increased between 2019 and 2020, with a decrease in 2021 probably due to shortages. Dexchlorpheniramine (DEX) and fluoxetine (FLU) fell, returning to growth in 2021. While the PECest of diazepam (DIA) increased over these 3 years, ethinylestradiol (EE2) decreased possibly due to the prioritization of PHC in the treatment of COVID-19. The largest QR were from FLU, EE2 and AZI. The consumption pattern of these drugs did not reflect their environmental risk because the most consumed ones have low toxicity. It is worth noting that some data may be underestimated due to the incentive given during the pandemic to the consumption of certain groups of drugs.

Foi avaliada a relação entre a distribuição de medicamentos usados na pandemia por SARS-COV-19 no município do Rio de Janeiro e o nível de risco ambiental estimado provocado por seus resíduos. Foi coletada a quantidade de medicamentos distribuídos pelas unidades de atenção primária à saúde (APS) entre 2019 e 2021. O quociente de risco (QR) correspondeu à razão entre a concentração ambiental preditiva estimada (PECest), obtida pelo consumo e excreção de cada fármaco, e a sua concentração preditiva não efetiva (PNEC). Os PECest da azitromicina e da ivermectina aumentaram entre 2019 e 2020, tendo uma queda em 2021 provavelmente devido ao desabastecimento. Já o da dexclorfeniramina (DEX) e da fluoxetina (FLU) tiveram uma queda, retornando o crescimento em 2021. Enquanto o PECest do diazepam (DIA) aumentou ao longo desses três anos, o etinilestradiol (EE2) diminuiu, possivelmente pela priorização da APS no tratamento da COVID-19. Os maiores QR foram de FLU, EE2 e AZI. O padrão de consumo desses medicamentos não refletiu seu risco ambiental, pois os mais consumidos possuem baixa toxicidade. Vale destacar que alguns dados podem estar subestimados devido ao incentivo que foi dado durante a pandemia para o consumo de determinados grupos de fármacos.

The use of toys by nursing as a therapeutic resource in the care of hospitalized children.

OBJECTIVES: to describe the use of toys by nursing during the care of children in the inpatient unit; to analyze the factors that influence the use of therapeutic toys by nursing in the care of hospitalized children. METHODS: qualitative research, conducted in a pediatric hospital in Rio de Janeiro between July and August 2019. Semi-structured interview and thematic analysis were used as methodological procedure. RESULTS: the 12 nurses and 7 nursing technicians revealed minimizing fear, relieving tension, and creating a bond between the child and the professional as the main benefits; they use as resources: children's toys, hospital materials, cartoons, and children's videos. The high demand for work, deficit of human resources, and appropriate ludic materials are factors that interfere with the use of toys as a therapeutic resource. FINAL CONSIDERATIONS: although the participants recognize the importance of the toy as a therapeutic resource, there is no systematization of its use in pediatric practice.

Biodegradation of 14C-dicofol in wastewater aerobic treatment and sludge anaerobic biodigestion.

Organic micropollutants are often found in domestic and industrial effluents. Thus, it is important to learn their fate, the metabolites generated and their sorption during biological treatment processes. This work investigated the biodegradation of 14C-dicofol organochloride during wastewater aerobic treatment and sludge anaerobic biodigestion. The performance of these processes was evaluated by physical-chemical parameters. Radioactivity levels were monitored in both treatments, and residues of dicofol (DCF) and dichlorobenzophenone (DBP) were quantified by HPLC/UV. The efficiency of the aerobic and anaerobic processes was slightly reduced in the presence of DCF and DBP. After aerobic treatment, only 0.1% of DCF was mineralized, and 57% of radioactivity remained sorbed on biological sludge as DBP. After 18 days of anaerobiosis, only 3% of DCF and 5% of DBP were detected in the sludge. However, 70% of radioactivity remained in the sludge, probably as other metabolites. Dicofol was biodegraded in the investigated process, but not mineralized.

Bacillus thuringiensis monogenic strains: screening and interactions with insecticides used against rice pests.

The screening of Bacillus thuringiensis (Bt) Cry proteins with high potential to control insect pests has been the goal of numerous research groups. In this study, we evaluated six monogenic Bt strains (Bt dendrolimus HD-37, Bt kurstaki HD-1, Bt kurstaki HD-73, Bt thuringiensis 4412, Bt kurstaki NRD-12 and Bt entomocidus 60.5, which codify the cry1Aa, cry1Ab, cry1Ac, cry1Ba, cry1C, cry2A genes respectively) as potential insecticides for the most important insect pests of irrigated rice: Spodoptera frugiperda, Diatraea saccharalis, Oryzophagus oryzae, Oebalus poecilus and Tibraca limbativentris. We also analyzed their compatibility with chemical insecticides (thiamethoxam, labdacyhalothrin, malathion and fipronil), which are extensively used in rice crops. The bioassay results showed that Bt thuringiensis 4412 and Bt entomocidus 60.5 were the most toxic for the lepidopterans, with a 93% and 82% mortality rate for S. frugiperda and D. saccharalis, respectively. For O. oryzae, the Bt kurstaki NRD-12 (64%) and Bt dendrolimus HD-37 (62%) strains were the most toxic. The Bt dendrolimus HD-37 strain also caused high mortality (82%) to O. poecilus, however the strains assessed to T. limbativentris caused a maximum rate of 5%. The assays for the Bt strains interaction with insecticides revealed the compatibility of the six strains with the four insecticides tested. The results from this study showed the high potential of cry1Aa and cry1Ba genes for genetic engineering of rice plants or the strains to biopesticide formulations.

"Together We Stand": A Pilot Study Exploring the Feasibility, Acceptability, and Preliminary Effects of a Family-Based Psychoeducational Intervention for Patients on Hemodialysis and Their Family Caregivers.

This pilot study aimed to assess the feasibility, acceptability, and preliminary effects of a family-based psychoeducational intervention for patients undergoing hemodialysis (HD) and their family members. This was a single-group (six dyads), six-week, pre-post pilot study, delivered in a multifamily group format. Feasibility was based on screening, eligibility, content, retention, completion, and intervention adherence rates. Acceptability was assessed at post-intervention through a focus group interview. Self-reported anxiety and depression and patients' inter-dialytic weight gain (IDWG) were also measured. The screening (93.5%), retention (85.7%), and completion (100%) rates were satisfactory, whereas eligibility (22.8%), consent (18.4%), and intervention adherence (range: 16.7-50%) rates were the most critical. Findings showed that participants appreciated the intervention and perceived several educational and emotional benefits. The results from the Wilcoxon Signed-Rank Test showed that a significant decrease in anxiety symptoms (p = 0.025, r = 0.646) was found, which was followed by medium to large within-group effect sizes for changes in depression symptoms (p = 0.261, r = 0.325) and patients' IDWG (p = 0.248, r = 0.472), respectively. Overall, the results indicated that this family-based psychoeducational intervention is likely to be feasible, acceptable, and effective for patients undergoing HD and their family caregivers; nonetheless, further considerations are needed on how to make the intervention more practical and easily implemented in routine dialysis care before proceeding to large-scale trials.

Cyclic alternation of quiet and active sleep states in the octopus.

Previous observations suggest the existence of 'Active sleep' in cephalopods. To investigate in detail the behavioral structure of cephalopod sleep, we video-recorded four adult specimens of Octopus insularis and quantified their distinct states and transitions. Changes in skin color and texture and movements of eyes and mantle were assessed using automated image processing tools, and arousal threshold was measured using sensory stimulation. Two distinct states unresponsive to stimulation occurred in tandem. The first was a 'Quiet sleep' state with uniformly pale skin, closed pupils, and long episode durations (median 415.2 s). The second was an 'Active sleep' state with dynamic skin patterns of color and texture, rapid eye movements, and short episode durations (median 40.8 s). 'Active sleep' was periodic (60% of recurrences between 26 and 39 min) and occurred mostly after 'Quiet sleep' (82% of transitions). These results suggest that cephalopods have an ultradian sleep cycle analogous to that of amniotes.

[Review of national and international legal and regulatory mechanisms on the management of drugs and the residues thereof]. / Revisão dos dispositivos legais e normativos internacionais e nacionais sobre gestão de medicamentos e de seus resíduos.

This paper presents a descriptive review of laws and regulations on the management of drugs and the residues thereof adopted by countries in Europe, the Americas and Australia. This review integrates relevant points of official documents of regulatory agencies in these countries, as well as important scientific works. All countries surveyed carry out drug management concomitant with the management of the residues thereof, ranging from awareness programs on the rational use and the risks of drugs through to the collection and safe disposal of such residues. Germany, the USA and Sweden demand a prior assessment of the environmental impact caused by a given drug as a criterion for its registration. Sweden is noteworthy in that it periodically updates a list of essential drugs based on risk assessment and the environmental risks posed by the residues thereof. In Brazil, the legal measures proposed including rational prescription and reverse logistics have not yet been effectively implemented. Prior environmental impact assessment safeguards the risks to human health and the wild biota caused by exposure to drug residues. Therefore, these international models could serve as a basis for discussion and/or legal and regulatory changes in Brazil.

Este trabalho apresenta uma revisão descritiva de leis e normas adotadas pelos países da Europa, das Américas e Austrália sobre gestão de medicamentos e de seus resíduos. Esta revisão integra pontos relevantes de documentos oficiais das agências reguladoras desses países, bem como de trabalhos científicos importantes. Todos os países pesquisados realizam gestão de medicamentos concomitantemente com a gestão de seus resíduos, atuando desde programas de conscientização sobre o uso racional e os riscos dos medicamentos até na coleta e disposição segura de seus resíduos. A Alemanha, os EUA e a Suécia exigem uma avaliação prévia do impacto ambiental provocado pelo medicamento como critério de seu registro. Em destaque, a Suécia que periodicamente atualiza uma lista de medicamentos essenciais baseada na avaliação do risco e do perigo ambiental de seus resíduos. No Brasil, as medidas legais propostas como prescrição racional e logística reversa ainda não foram efetivamente implementadas. A avaliação prévia de impacto ambiental resguarda os riscos à saúde humana e da biota selvagem causados pela exposição aos resíduos de medicamentos. Portanto, esses modelos internacionais poderiam servir de base para discussões e/ou alterações legais e normativas no Brasil.

Fate of organochlorine (14)C-dicofol in a lab-scale wastewater treatment.

The fate of organochlorine (14)C-dicofol in activated sludge process was investigated. Results showed that the major part of radioactivity remained adsorbed on biological sludge. Consequently, its final disposal deserves special attention. The small amounts of dicofol, biotransformed or not, which remained in the treated effluent could contaminate receiving bodies.

Regulation of the synthetic estrogen 17α-ethinylestradiol in water bodies in Europe, the United States, and Brazil.

The synthetic estrogen 17α-ethinylestradiol, the principal component of oral contraceptives, has been identified as one of the main compounds accounting for adverse effects on the endocrine system in various species. This study aimed to analyze the state-of-the-art in legislation and guidelines for the control of this synthetic estrogen in water bodies in Europe and the United States and to draw a parallel with the Brazilian reality. Countries have generally attempted to expand the regulation and monitoring of certain emerging micropollutants not previously covered by legislation. Europe is more advanced in terms of water quality, while in the United States this estrogen is only regulated in water for human consumption. Brazil still lacks legal provisions or standards for this estrogen, which can be explained by the relatively limited maturity of the country's system for controlling water pollutants.

Factors controlling nitrous oxide emissions from a full-scale activated sludge system in the tropics.

Despite interest in characterizing nitrous oxide (N2O) emissions from wastewater treatment plants (WWTPs) in several parts of the globe, there are few studies in tropical zones. This study focus on the contribution of the scientific knowledge of anthropogenic nitrogen greenhouse gas emissions to climate change in tropical countries, investigating factors controlling N2O emissions in a non-biological nitrogen removal municipal WWTP. In terms of operational parameters, dissolved oxygen (DO) concentrations displayed a biphasic impact on N2O production and emission, with the highest emission at DO of 2.0 mg O2 L(-1). The low solids retention time of 3 days also played a significant role, leading to nitrite accumulation, which is an important trigger for N2O production during nitrification. Furthermore, other factor especially important for tropical countries, namely, temperature, also had a positive correlation with N2O production. Emission factors estimated for this study were 0.12 (0.02-0.31)% of the influent total nitrogen load and 8.1 (3-17) g N2O person(-1) year(-1), 2.5 times higher than currently proposed emission factors. Therefore, the highly variability and dependence on operational parameters reinforce the use of a single emission factor is inadequate, especially for developing countries with limited or variable extent of biological wastewater treatment and in regions of the world with widely varying climate patterns.
