RESUMO
Antiretroviral therapy (ART) adherence is crucial for health outcomes of people living with HIV (PLHIV), influenced by a complex interplay of individual, community, and household factors. This article focuses on the influence of household factors, as well as individual and community factors, on ART adherence among PLHIV in Cape Town who have recently initiated ART. Baseline data for a cluster-randomized controlled trial were collected from 316 PLHIV in 12 districts in Cape Town between 6th May 2021 and 22nd May 2022. Zero-inflated Poisson models, with cluster-adjusted standard errors, were used to analyse the association between individual, household, and community factors and ART adherence measures. At the household-level, household support was associated with both better self-rated adherence (exp(ß) = 0.81, z = - 4.68, p < 0.001) and fewer days when pills were missed (exp(ß) = 0.65, z = - 2.92, p = 0.003). Psychological violence (exp(ß) = 1.37, z = 1.97, p = 0.05) and higher household asset scores (exp(ß) = 1.29, z = - 2.83, p = 0.05) were weakly associated with poorer ART adherence. At the individual-level, male gender (exp(ß) = 1.37, z = 3.95, p < 0.001) and reinitiating ART (exp(ß) = 1.35, z = 3.64, p < 0.001) were associated with worse self-rated ART adherence; higher education levels (exp(ß) = 0.30 times, z = - 3.75, p < 0.001) and better HIV knowledge (exp(ß) = 0.28, z = - 2.83, p = 0.005) were associated with fewer days where pills were missed. At the community-level, community stigma was associated with worse self-rated ART adherence (exp(ß) = 1.24, z = 3.01, p = 0.003). When designing interventions to improve ART adherence, household, individual and community factors should all be considered, particularly in addressing gender-based disparities, reducing stigma, tackling violence, and enhancing household support.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

RESUMEN: La adherencia a la terapia antirretroviral (TAR) es crucial para los resultados de salud de las personas que viven con el VIH (PLHIV), influenciada por una compleja interacción de factores individuales, comunitarios y del hogar. Este artículo se centra en la influencia de los factores del hogar, individuales y comunitarios en la adherencia al TAR entre personas que iniciaron recientemente el TAR en Ciudad del Cabo. Se recopilaron datos de referencia para un ensayo de control aleatorio por grupos de 316 PLHIV en 12 distritos de Ciudad del Cabo entre el 6 de mayo de 2021 y el 22 de mayo de 2022. Se utilizaron modelos de Poisson inflados a cero, con errores estándar ajustados por conglomerado para estudiar la asociación entre factores individuales, del hogar o comunitarios con dos medidas de adhesión al TAR: por un lado la auto declaración de adhesión, y por otro la cantidad de días en que se olvidó de tomar la medicina en los últimos 4 días. A nivel del hogar, el apoyo del hogar se asoció con una mejor adherencia auto declarada (exp(ß) = 0.81, z = − 4.68, p < 0.001) y menos días en los que se omitió la medicina (exp(ß) = 0.65, z = − 2.92, p = 0.003). La violencia psicológica (exp(ß) = 1.37, z = 1.97, p = 0.05) y las puntuaciones más altas de activos del hogar (exp(ß) = 1.29, z = − 2.83, p = 0.05) se asociaron con una peor adherencia al TAR. A nivel individual, el sexo masculino (exp(ß) = 1.37, z = 3.95, p < 0.001) y el reinicio del TAR (exp(ß) = 1.35, z = 3.64, p < 0.001) se asociaron con una peor adherencia al TAR autodeclarada; niveles de educación más altos (exp(ß) = 0.30 times, z = − 3.75, p < 0.001) y un mejor conocimiento sobre el VIH (exp(ß) = 0.28, z = − 2.83, p = 0.005) se asociaron con menos días en los que se omitió la medicina. A nivel comunitario, el estigma comunitario se asoció con una peor autodelaración de adhesión del TAR (exp(ß) = 1.24, z = 3.01, p = 0.003). Para mejorar la adherencia al TAR, se deben tener en cuenta los factores del hogar, así como los individuales y comunitarios, particularmente al abordar las disparidades de género, reducir el estigma, abordar la violencia y mejorar el apoyo del hogar.
RESUMO
AIM: To explore and describe acute care nurses' decisions to recognise and respond to improvement in patients' clinical states as they occurred in the real-world clinical environment. DESIGN: A descriptive study. METHODS: Nine medical and eleven surgical nurses in a large Australian metropolitan hospital were individually observed during nurse-patient interactions and followed up in interview to describe their reasoning and clinical judgements behind observed decisions. Verbal description of observations and interviews were recorded and transcribed. Reflexive thematic analysis was used to analyse the data. RESULTS: The three themes constructed from the data were as follows: nurses checking in; nurses reaching judgements about improvements; and nurses deciding on the best person to respond. Acute care nurses made targeted assessment decisions based on predicted safety risks related to improvement in clinical states. Subjective and objective cues were used to assess for and make judgements about patient improvement. Acute care nurses' judgment of patient safety and a desire to promote patient centred care guided their decisions to select the appropriate person to manage improvement. CONCLUSIONS: The outcomes of this research have demonstrated that the proven safety benefits of acute care nurses' decision making in response to deterioration extend to improvement in patients' clinical states. In response to improvement, acute care nurses' decisions protect patients from harm and promote recovery. IMPLICATIONS FOR PATIENT CARE: Early recognition and response to improvement enable acute care nurses to protect patients from risks of unnecessary treatment and promote recovery. IMPACT: This study makes explicit nurses' essential safety role in recognising and responding to improvement in patients' clinical states. Healthcare policy and education must reflect the equal importance of assessment for and management of deterioration and improvement to ensure patients are protected and provided with safe care.
RESUMO
BACKGROUND: Treatment delivery safety and accuracy are essential to control the disease and protect healthy tissues in radiation therapy. For usual treatment, a phantom-based patient specific quality assurance (PSQA) is performed to verify the delivery prior to the treatment. The emergence of adaptive radiation therapy (ART) adds new complexities to PSQA. In fact, organ at risks and target volume re-contouring as well as plan re-optimization and treatment delivery are performed with the patient immobilized on the treatment couch, making phantom-based pretreatment PSQA impractical. In this case, phantomless PSQA tools based on multileaf collimator (MLC) leaf open times (LOTs) verifications provide alternative approaches for the Radixact® treatment units. However, their validity is compromised by the lack of independent and reliable methods for calculating the LOT performed by the MLC during deliveries. PURPOSE: To provide independent and reliable methods of LOT calculation for the Radixact® treatment units. METHODS: Two methods for calculating the LOTs performed by the MLC during deliveries have been implemented. The first method uses the signal recorded by the build-in detector and the second method uses the signal recorded by optical sensors mounted on the MLC. To calibrate the methods to the ground truth, in-phantom ionization chamber LOT measurements have been conducted on a Radixact® treatment unit. The methods were validated by comparing LOT calculations with in-phantom ionization chamber LOT measurements performed on two Radixact® treatment units. RESULTS: The study shows a good agreement between the two LOT calculation methods and the in-phantom ionization chamber measurements. There are no notable differences between the two methods and the same results were observed on the different treatment units. CONCLUSIONS: The two implemented methods have the potential to be part of a PSQA solution for ART in tomotherapy.
RESUMO
The former Spanish Netherlands experienced a period of social, cultural and economic prosperity in the seventeenth century, with Antwerp as its most important commercial and artistic centre. The era's vibrant art scene, once pivotal culturally, economically, and diplomatically, now offers invaluable insights for scientific studies on art, trade, and craftsmanship. In a study on 294 panel paintings by or related to two famous Flemish artists, Jacques Jordaens (1593-1678) and Anthony van Dyck (1599-1641), we applied classical art historical techniques, archival research, dendrochronology, and the study of panel maker's and guild marks on the painting's reverse to gain insights into the precise time of tree felling, the geographical provenance of the wood, and the panel makers patronised by the painters. The majority of the paintings (~ 80%), which were subjected to a dendrochronological analysis, could be dated and the results accorded well with the concomitant art historical assessment on authorship. Besides an active and well-known Baltic timber trade which provided over 71% of all the planks examined, straight-grained oak trees were also sourced from western Central Europe (20%). Interestingly, planks from the Baltic and the Ardennes region (France/Belgium) were used together in three different paintings, likely cut apart from larger panels. Employing a multidisciplinary approach to a comprehensive painting collection by individual painters provides not only a new tool to determine a painting's date and authorship but also allows for a better understanding of the contemporary timber trade and associated craftsmanship.
RESUMO
Research on personality in leadership indicates that self-selection to leadership careers and artistic careers correlates with diverging personality profiles. People in leadership careers traditionally display lower neuroticism and higher conscientiousness than artistic individuals. In between, there are individuals entering arts management careers. To study these individuals directly, we collected Norwegian data from 91 musical theater students and 102 arts management students and compared with 109 business management students. As expected, conscientiousness and neuroticism predicted artistic careers against business management careers, aligned with the "arts for arts' sake" myth of artists. Interestingly, arts management careers were not different from artistic careers. They weren't more motivated to take on leadership roles than performing artists either. However, the Highly Sensitive Person Scale indicated that narrower traits of sensitivity predicted higher levels of motivation to lead in many artists. Some arts and arts management students seem to bring unique talents into forms of leadership particularly useful for artistic organizations. Our findings are discussed in terms of how leadership characteristics operate in the field of art, and the effect of domain-specific characteristics in this setting.
RESUMO
Objectives: To systematically synthesize the current evidence on the effects of art-based interventions on improving anxiety, depression, stress, sleep, and well-being of cancer caregivers. Design: A systematic review. Methods: We searched PubMed, EMBASE, Web of Science, CINAHL, PsycINFO, and Cochrane Central Register of Controlled Trials databases from their inception up to April 2024. Studies exploring the effects of art-based interventions on the psychological symptoms of cancer caregivers were included. We did not restrict the publication to the particular study designs, including randomized controlled trials, quasiexperimental studies, and qualitative studies. Results: Fifteen studies of 607 participants were identified in this systematic review. Overall, the existing studies provided preliminary evidence to suggest that art-based interventions may benefit cancer caregivers in improving anxiety, depression, stress, caregiver burden, and quality of life. However, the relatively low quality of the current evidence limits the efficacy of these findings. Conclusions: According to the existing evidence, the therapeutic benefits of using art-based interventions for improving the psychological well-being of cancer caregivers are uncertain. More high-quality and well-designed studies are still required to confirm the psychological effectiveness of art-based interventions for cancer caregivers in the future.
RESUMO
Comparisons of aesthetic valence and of sensory magnitude are subject to similar order effects, indicating an evolved mechanism that sharpens also aesthetic discrimination. As the foundation of pleasantness and aesthetic valence of an object, an optimal level of evoked arousal or, in more recent research, of information load, has been proposed. According to discrepancy theory, this evoked effect is modulated by the object's deviation from the current adaptation level (AL). The AL is built up and updated by pooling recent stimulation. A model based on these concepts is proposed here, and it is illustrated by results of empirical studies by the author's students. For everyday objects such as cars and ladies' clothes, rated beauty was related by a U-shaped function to rated modernity. Minimal beauty occurred for intermediate modernity. For ladies' clothes, this minimum was situated higher on the modernity scale for females and extraverts. As modernity can be seen as the amount of deviation from the AL which represents the usual, this shift could be explained by faster upward adjustment of the AL. In contrast, for paintings the relation between modernity and beauty was inversely U-shaped. This could be due to paintings intrinsically carrying more information than other objects, as indicated by ratings of hard-to-access, with which rated beauty had an inverse U-shaped relation. In a factor-analytic study of preference for 42 paintings four orthogonal factors were extracted, interpreted as High and Low modernity, and High and Low information content. This could yield a rudimentary empirical typology of art.

We investigated the influence of the medium on the perception of depicted objects and materials. Oil paintings and their reproductions in engravings were chosen because they are vastly distinctive media while having completely identical content. A total of 15 pairs were collected, consisting of 88 fragments depicting different materials, including fabric, skin, wood and metal. Besides the original condition, we created three manipulations to understand the effect of colour (a greyscale version) and contrast (equalised histograms towards both painting and engraving). We performed rating experiments on five attributes: three-dimensionality, glossiness, convincingness, smoothness and softness. An average of 25 participants finished each of the 20 online experimental sessions (five attributes X four conditions). Besides clear correlations between the two media, the differences mainly show in their means (different levels of perceived attributes) and standard deviations (perceived range). In most sessions, paintings depict a wider range than engravings. In addition, it was the histogram equalisation (global contrast) that made the most impact on perceived attributes, rather than colour removal. This suggests that engravers compensated for the lack of colour by exploiting the possibilities of local contrast.
RESUMO
OBJECTIVE: To determine if industry payments to physicians are associated with a difference in ART practices and outcomes. DESIGN: Retrospective Cohort SETTING: ART centers in the United States SUBJECTS: ART centers EXPOSURES: Industry payments reported to Open Payments 2020 database MAIN OUTCOME MEASURES: Live birth rate, frozen embryo transfer (FET) rate, intracytoplasmic sperm injection (ICSI) rate, preimplantation genetic testing (PGT) rate and percentage of patients >40 years of age were obtained from Center for Disease Control 2020 database. Linear regression analysis was performed comparing the percentage of physicians per center receiving industry payments to clinic-level outcomes. RESULTS: A total of 873 REI physicians received payments in the 2020 database. At least one physician received a payment in 80.5% (437/543) of IVF centers. 873/1724 REI physicians (50.6%) received at least one payment in 2020. Live birth rate, ICSI rate, FET rate, PGT rate and percentage of patients >40 years of age did not significantly differ between centers by percentage of physicians receiving industry payments. However, in sub-analysis of 99 large centers (defined as 5 physicians or more), each percentage increase of physicians receiving industry payments was associated with a 0.20% (CI 0.02-0.39, p = 0.03) PGT rate increase and a 0.14% (CI 0.05-0.24, p <0.001) FET rate increase. Live birth rate, ICSI rate, and percentage of patients >40 were not associated with increased industry payment rates to physicians. CONCLUSIONS: Industry payments were not associated with differences in IVF center outcomes overall. However, large centers with more physicians receiving industry payments may be more likely to utilize additional procedures such as PGT and FET, without improvement in final outcomes such as live birth rate. Further research is needed to determine whether these differences reflect the industry payment influence versus individual center/provider practice habits in larger practices.
RESUMO
Public health measures associated with coronavirus disease 2019 (COVID-19), such as lockdowns and quarantine of suspected cases, can negatively affect children's mental health status. Although the current crisis provides personal growth and family cohesion opportunities, pitfalls appear to outweigh the benefits. The magnitude and quality of its impact on children depend on several factors, including anxiety, lack of social contact, and a reduced opportunity for stress regulation, along with an increased risk for parental mental health issues, child maltreatment, and domestic violence. Children with special needs and social disadvantages like trauma experiences, disabilities, pre-existing mental illness, e.g., autism spectrum disorders and hyperactivity, and low socioeconomic status, may be at higher risk in this context. Here, the potentials social support can provide for pediatrics, both healthy children and children with special needs, are reviewed after an overview of quarantine's adverse effects on this special population during a pandemic. The most common psychological issues associated with the COVID-19 pandemic are sleep disorders, mood swings, depression, anxiety, decreased attention, stress, irritability, anger, and fear. Moreover, the impact of COVID-19 on children's physical health includes weight gain, reduced physical activity, immune dysregulation, and cardiometabolic disorders. All support systems, involving parents, teachers/school counselors, pediatricians, mental healthcare workers, and Health and Art (HEART) groups, need to enter the scene and make their share of children's mental health care.

Alzheimer's disease (AD) presents a growing global challenge, with an increasing prevalence and significant impact on individuals and public health. Effective pharmacological treatments directly impacting the disease are still lacking, highlighting the importance of programs and interventions aimed at improving the wellbeing of those affected. The present feasibility study aimed to evaluate the effectiveness and feasibility of the Alzheimer's patients Interaction through Digital and Arts (AIDA) program. AIDA's main objective is to enhance perceived wellbeing and quality of life of people with AD and their caregivers through a series of structured activities through museum- and art-based activities over five sessions. Pre- and post-program evaluations were conducted using Visual Analog Scales (VASs) to measure various dimensions of perceived wellbeing such as confidence, happiness, interest, optimism, and wellness. Results showed significant improvements in all considered dimensions for people with AD following AIDA activities, highlighting its potential to enhance overall wellbeing. Caregivers also reported increased perceived wellness post-program, demonstrating some positive effects also in healthy participants. The feasibility of AIDA was supported by positive feedback and engagement of participants. Overall, the AIDA program offers a non-intrusive and engaging approach to improve the perceived wellbeing of people with AD and caregivers while facilitating meaningful experiences (e.g., silence, sharing etc.) in cultural settings.

RESUMO
BACKGROUND: Adolescents and young adults (AYA) living with HIV have been shown to have lower rates of viral load testing and viral suppression as compared to older adults. We examined trends over time and predictors of HIV viral load monitoring and viral suppression among AYA in a large HIV treatment programme in Dar es Salaam, Tanzania. METHODS: We analysed longitudinal data of AYA aged 10-24 years initiated on antiretroviral therapy between January 2017 and October 2022. Trend models were used to assess changes in HIV viral load testing and viral suppression by calendar year. Generalised estimating equations were used to examine the relationship of sociodemographic and clinical factors with HIV viral load testing and viral suppression. RESULTS: Out of 15,759 AYA, the percentage of those who received a 6-month HIV viral load testing increased from 40.6% in 2017 to 64.7% in 2022 and, a notable annual increase of 5.6% (p < 0.001). A higher HIV viral load testing uptake was observed among 20- to 24-year-olds (87.7%) compared to 10- to 19-year-olds (80.2%) (p < 0.001). The likelihood of not receiving an HIV viral load test within 12 months of antiretroviral therapy initiation was higher among 10- to 19-year-olds (adjusted odds ratio [aOR] = 1.7; 95% confidence interval [CI] = 1.4-2.0), advanced HIV disease (aOR = 1.3; 95% CI = 1.12-1.53), normal nutrition status at enrolment aOR 2.6 (95% CI = 1.59-4.26) and initiation of non-nucleoside reverse transcriptase inhibitors regimen aOR 1.2 (95% CI = 1.08-1.34). The proportion of AYA with viral suppression increased from 83.0% in 2017 to 94.6% in 2022. Notably, the overall trend in viral suppression increased significantly at 2.4% annually. The risk of not achieving viral suppression was greater among 10- to 14-year-olds (aOR = 2; 95% CI = 1.75-2.43) and 15- to 19-year-olds (aOR = 1.4; 95% CI = 1.24-1.58) as compared to 20-24 years; being male (aOR = 1.16; 95% CI = 1.02-1.32); undernourished (aOR = 1.53; 95% CI = 1.17-1.99); in WHO Stage II (aOR = 1.16; 95% CI = 1.02-1.33) and III (aOR = 1.21; 95% CI = 1.03-1.42) and being on an non-nucleoside reverse transcriptase inhibitors regimen (aOR = 1.32; 95% CI = 1.18-1.48). CONCLUSION: HIV viral load testing uptake at 6 months of antiretroviral therapy initiation and viral suppression increased from 2017 to 2022; however, overall HIV viral load testing was suboptimal. Demographic and clinical characteristics can be used to identify AYA at greater risk for not having HIV viral load test and not achieving viral suppression.
RESUMO
BACKGROUND: Tuberculosis-immune reconstitution inflammatory syndrome is an atypical, immoderate immune response mounted by the refurbishing immune system against the mycobacterium tuberculosis, commonly seen in HIV-infected individuals. ART significantly enhances one's immunity. However, this enhancement in immunity also sets off a number of inflammatory processes termed as Immune Reconstitution Inflammatory Syndrome (IRIS). METHODS: This observational study was conducted with the aim of assessing the incidence and pattern of TB-IRIS in people living with HIV/AIDS on ART registered at the ART Centre of S.C.B. Medical College and Hospital, Cuttack. They were evaluated for their plasma viral load and CD4 count at baseline. Thereafter, the plasma viral load was assessed every week and the CD4 count was assessed fortnightly. Each study participant was followed-up for a period of three months to look for any onset of TB-IRIS. RESULTS: A total of 286 patients were included the study. The overall incidence of TB-IRIS was 7.7%. The occurrence of paradoxical TB-IRIS was nearly double than ART-associated TB-IRIS. There was a significant rise in the CD4 cell count in the patients of both paradoxical (p = 0.001) and ART-associated (p = 0.017) TB-IRIS. The plasma viral load at baseline also showed significant differences from the levels documented at the appearance of the TB-IRIS both in both the types i.e. paradoxical (p = 0.001) and ART-associated (p = 0.012) TB-IRIS. CONCLUSION: People with HIV/TB coinfection experience high morbidity and death from all kinds of TB-IRIS, necessitating specific attention. As HIV-positive cases and implementation of ART continue to rise, it's vital to quickly rule out TB coinfection.

Human embryonic aneuploidy may represent one of the final frontiers in assisted reproductive technology (ART), primarily secondary to oocyte aneuploidy. Mammalian oocytes possess unique characteristics predisposing them to much higher rates of aneuploidy than sperm or most somatic cells. Some of these characteristics are age-independent, while others result from reproductive aging and environmental toxicity. A detailed understanding of these properties may lead to novel diagnostic and therapeutic tools designed to detect and prevent oocyte and embryonic aneuploidy, to overcome this ultimate barrier to success in ART.
RESUMO
Comprehensive healthcare for all includes gender-affirming hormone therapy for transgender and nonbinary individuals. It is the unique privilege of HIV providers, who take care of a disproportionate number of transgender people, to provide gender-affirming hormone therapy along with antiretroviral therapy. It could increase viral suppression rates, increase overall health outcomes, and decrease gender health disparities.
RESUMO
This paper deals with karate activity in the areas of physical culture in the broad sense. It is a concise and clear approach to the topic, which aimed to conceptualise the inclusion of karate in areas of physical culture as a contemporarily attractive physical activity. Karate was described here as a combat sport, martial art, and self-defence system in the following areas of physical culture: physical education, physiotherapy, recreation, sports, and tourism. Reference here was made to physical activity focused on bunkai (circuit interpretation exercises), kata (circuit exercises), kihon (technical exercises), and kumite (combat exercises). It has been determined that practitioners' involvement in karate culture affects their level of sense of coherence. In addition, the conditioning for using karate in physical culture to the maintenance of health was mentioned. Here, reference was made to the perceptual perspective of the bodily and mental practice of karate for health. It has been established that this can be effective by adopting only the objectives of karate as martial art. Based on the above, it was concluded that practising karate is present in all areas of physical culture as combat sport, martial art, and self-defence system, but practising karate only as martial art provides opportunities for maintenance of health.
RESUMO
BACKGROUND: Hypothyroidism, a common worldwide syndrome caused by insufficient thyroid hormone secretion, affects number of people at different ages. Artemisinin (ART), a well-known effective agent in the treatment of malaria, also has anti-oxidative stress functions in various diseases. The L1 cell adhesion molecule exerts multiple protective roles in diseased systems. The aim of the present study was to evaluate the role of ART in adult male hypothyroid rats and the underlying mechanisms. METHODS: The propylthiouracil (PTU) rat model was treated with or without 5 mg/kg ART and with or without L1 short-interfering RNA (siRNA), followed by the experiments to determine the effect of ART on thyroid function, depression and anxiety, cognition impairments, liver, kidney and heart functions, and oxidative stress. RESULTS: In the current study, it was shown that ART can ameliorate thyroid function, mitigate depression and anxiety symptoms, attenuate cognition impairments, improve liver, kidney and heart functions, and inhibit oxidative stress; however, the effects exerted by ART could not be observed when L1 was silenced by L1 siRNA. CONCLUSION: These results indicated that ART can upregulate the L1 cell adhesion molecule to ameliorate thyroid function and the complications in adult male hypothyroid rats, laying the foundation for ART to be a novel strategy for the treatment of hypothyroidism.
