Quality, acceptability and usability of self-sampling kits used by non-healthcare professionals for STI diagnosis in Spain: a single-blind study.

OBJECTIVES: Sexually transmitted infections (STIs) have markedly increased over the last decade in Spain, calling for prevention and control innovative approaches. While there is evidence indicating the effectiveness of self-sampling for STI diagnosis, no kits for this purpose have been authorised in Spain. METHODS: A prospective single-blind cross-sectional study carried out between November and December 2022 in an STI clinic in Madrid, Spain, to determine the validity, feasibility and acceptability of self-sampling kits used by non-healthcare professionals from vagina, pharynx, rectum and urethra to diagnose Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). Self-samples were compared with samples collected by healthcare professional (HC samples) and analysed by PCR. Frequency of CT and NG diagnosis by sample type was compared using McNemar's test for paired data. Sensitivity and specificity of self-samples for CT and NG diagnosis were also calculated. RESULTS: 306 self-samples from 51 participants were analysed. 80% were men with median age of 33 (IQR: 28-38) years. Self-samples and HC samples showed no significant statistical differences in CT and NG diagnosis. Self-samples had a sensitivity of 81% for CT and 93% for NG, with a specificity of 97% for CT and 95% for NG. More than 90% of participants had no difficulty understanding the kit instructions and 71% expressed high levels of satisfaction with the self-sampling kit. CONCLUSION: Self-sampling kits for CT and NG diagnosis can be safely and effectively used by non-healthcare professionals in Spain. National strategies for STI prevention and control should prioritise self-sampling strategies.

Factors influencing the health-related quality of life of older men and women living with HIV in Spain.

The number of older people living with HIV (OPLHIV) is increasing worldwide. However, little is known about the factors that better predict their health-related quality of life (HRQoL). We administered the validated WHOQoL-HIV BREF questionnaire to 247 Spanish OPLHIV (192 men and 55 women). In addition to the six domains of the questionnaire, we constructed a seventh domain as theaverage of punctuations of all domains. Multivariable Poisson regression models with robust estimates by sex were constructed for the seven domains (14 in total). The best-subset selection method together with Mallow's Cp metric was used to select the model factors. The percentage of variability explained by Poisson models ranged from15-38% for men and 29-70% for women. The analysis showed that women were most affected by ageing (four domains), mobility impairments (five domains), and mental disorders (five domains). The factors with the greatest negative influence on men were heterosexuality (six domains), mental disorders (six domains), being single (five domains), and poverty risk (three domains). Physical activity was found to improve HRQoL in both men (six domains) and women (four domains). Future OPLHIV programmes would benefit from considering sex specific HRQoL factors. This could also improve the cost-effectiveness of interventions.

A factorial cluster-randomised controlled trial combining home-environmental and early child development interventions to improve child health and development: rationale, trial design and baseline findings.

BACKGROUND: Exposure to unhealthy environments and inadequate child stimulation are main risk factors that affect children's health and wellbeing in low- and middle-income countries. Interventions that simultaneously address several risk factors at the household level have great potential to reduce these negative effects. We present the design and baseline findings of a cluster-randomised controlled trial to evaluate the impact of an integrated home-environmental intervention package and an early child development programme to improve diarrhoea, acute respiratory infections and childhood developmental outcomes in children under 36 months of age living in resource-limited rural Andean Peru. METHODS: We collected baseline data on children's developmental performance, health status and demography as well as microbial contamination in drinking water. In a sub-sample of households, we measured indoor kitchen 24-h air concentration levels of carbon monoxide (CO) and fine particulate matter (PM2.5) and CO for personal exposure. RESULTS: We recruited and randomised 317 children from 40 community-clusters to four study arms. At baseline, all arms had similar health and demographic characteristics, and the developmental status of children was comparable between arms. The analysis revealed that more than 25% of mothers completed primary education, a large proportion of children were stunted and diarrhoea prevalence was above 18%. Fifty-two percent of drinking water samples tested positive for thermo-tolerant coliforms and the occurrence of E.coli was evenly distributed between arms. The mean levels of kitchen PM2.5 and CO concentrations were 213 µg/m3 and 4.8 ppm, respectively. CONCLUSIONS: The trial arms are balanced with respect to most baseline characteristics, such as household air and water pollution, and child development. These results ensure the possible estimation of the trial effectiveness. This trial will yield valuable information for assessing synergic, rational and cost-effective benefits of the combination of home-based interventions. TRIAL REGISTRY: ISRCTN-26548981.

[HIV and human rights: political action to achieve ZERO stigma]. / VIH y derechos humanos: acción política para alcanzar CERO estigma.

According to Sustainable Development Goals 10.2 and 10.3, it is imperative to promote the elimination of discriminatory laws, as well as implement policies and practices for the inclusion of vulnerable social groups on the social, economic and political fronts. In this regard, HIV-related discrimination and stigma remain unaddressed in many European Union countries. Fighting HIV-related stigma has been one of the main priorities of the Spanish Presidency of the Council of the European Union. This commitment was reflected in the High Level Meeting entitled HIV and Human Rights. Political action to achieve ZERO stigma. This meeting provided an opportunity to discuss a variety of strategies and agreements for eradicating stigma and discrimination associated with HIV in a variety of social, political, and institutional contexts.

Los objetivos de desarrollo sostenible 10.2 y 10.3 ponen de manifiesto la importancia de fomentar la eliminación de leyes discriminatorias, así como de implantar políticas y prácticas orientadas a la inclusión social, económica y política de los grupos sociales vulnerables. En este sentido, abordar la discriminación y el estigma asociados al VIH sigue siendo una asignatura pendiente dentro de los países que conforman la Unión Europea. De ahí que esta cuestión haya sido una prioridad política de la Presidencia española del Consejo de la Unión Europea, reflejada en la Reunión de Alto Nivel VIH y derechos humanos. Acción política para alcanzar CERO estigma. En esta reunión se abordaron diferentes estrategias y acuerdos para promover la eliminación del estigma y la discriminación asociada al VIH en diferentes ámbitos y dimensiones sociales, políticas e institucionales.

Analysis of the Initial Learning Curve for Robotic-Assisted Total Knee Arthroplasty Using the ROSA® Knee System.

Background/Objectives: Total knee arthroplasty (TKA) is a frequent procedure in orthopedic surgery. Advances in TKA include the development of robotic-assisted systems. Training in raTKA entails a learning curve to achieve proficiency comparable to conventional manual TKA (maTKA). Methods: We conducted a prospective study of the learning curve in raTKA using the Robotic Surgical Assistant (ROSA) Knee System. The study included 180 patients (90 raTKAs; 90 maTKAs) and three surgeons (one with >15 years of experience in maTKA). The cumulative sum control chart method (CUSUM) was used to define the transition from the learning phase to the mastered phase in raTKA. Results: The learning curves were 43 cases (experienced surgeons) and 61 cases (all surgeons). Mean operative times for both phases in raTKA were longer than in maTKA (p < 0.001). In raTKA, operative times in the learning phase were longer compared to those in the mastered phase (p < 0.001). Operative times in the learning and mastered phases for all surgeons in raTKA were significantly longer compared to those in maTKA (p < 0.001); however, operative times of the experienced surgeon in the mastered phase of raTKA and in maTKA showed no differences. Conclusions: The learning curve in raTKA is dependent upon the surgeon's previous experience in maTKA.

Sex differences in health-related quality of life and poverty risk among older people living with HIV in Spain: A cross-sectional study.

BACKGROUND: Current antiretroviral therapies have increased the life expectancy of people living with HIV (PLHIV). There is, however, limited evidence regarding the health-related quality of life (HRQoL) and living conditions of older people living with HIV (OPLHIV) in Spain. METHODS: We implemented a self-administered online questionnaire to identify sex differences in HRQoL and poverty risk among Spanish OPLHIV (PLHIV ≥50 years). Participants were contacted through non-governmental organisations. We used the standardised WHOQoL-HIV BREF questionnaire and the Europe 2020 guidelines to estimate HRQoL and poverty risk respectively. The statistical analysis included multivariable generalised linear models with potential confounding variables and robust estimates. RESULTS: The study included 247 OPLHIV (192 men and 55 women). On the WHOQoL-HIV BREF questionnaire, men scored higher on 84% of items and in all six domains. Women had significantly lower HRQoL in five domains: physical health (ß: -1.5; 95% CI: -2.5, -0.5; p: 0.002), psychological health (ß: -1.0; 95% CI: -1.9, -0.1; p: 0.036), level of independence (ß: -1.1; 95% CI: -1.9, -0.2; p: 0.019), environmental health (ß: -1.1; 95% CI: -1.8, -0.3; p: 0.008), and spirituality/personal beliefs (ß: -1.4; 95% CI: -2.5, -0.3; p: 0.012). No statistical differences were found in the domain of social relations. Poverty risk was considerable for both men (30%) and women (53%), but women were significantly more likely to experience it (OR: 2.9; 95% CI: 1.3, 6.5; p: 0.009). CONCLUSION: The aging of PLHIV is a public health concern. Our findings indicate that HRQoL and poverty risk among Spanish OPLHIV differ significantly by sex. Spain should, therefore, implement specific policies and interventions to address OPLHIV needs. The strategies must place a high priority on the reduction of sex inequalities in HRQoL and the enhancement of the structural conditions in which OPLHIV live.

Effectiveness of a home-environmental intervention package and an early child development intervention on child health and development in high-altitude rural communities in the Peruvian Andes: a cluster-randomised controlled trial.

BACKGROUND: Unsafe drinking water, poor sanitation and hygiene, exposure to household air pollution and low cognitive and socio-emotional stimulation are risk factors affecting children in low- and middle-income countries. We implemented an integrated home-environmental intervention package (IHIP), comprising a kitchen sink, hygiene education and a certified improved biomass cookstove, and an early child development (ECD) programme to improve children´s health and developmental outcomes in the rural high-altitude Andes of Peru. METHODS: We conducted a one-year cluster-randomised controlled trial among 317 children < 36 months divided into 4 arms (IHIP + ECD, IHIP, ECD, and Control) and 40 clusters (10 clusters per arm). ECD status (socio-emotional, fine and gross motor, communication, cognitive skills, and an overall performance) measured with the Peruvian Infant Development Scale and the occurrence of self-reported child diarrhoea from caretakers were primary outcomes. Secondary outcomes included the occurrence of acute respiratory infections and the presence of thermo-tolerant faecal bacteria in drinking water. The trial was powered to compare each intervention against its control arm but it did not allow pairwise comparisons among the four arms. Primary analysis followed the intention-to-treat principle. For the statistical analysis, we employed generalised estimating equation models with robust standard errors and an independent correlation structure. RESULTS: We obtained ECD information from 101 children who received the ECD intervention (individually and combined with IHIP) and 102 controls. Children who received the ECD intervention performed better in all the domains compared to controls. We found differences in the overall performance (64 vs. 39%, odd ratio (OR): 2.8; 95% confidence interval (CI): 1.6-4.9) and the cognitive domain (62 vs 46%, OR: 1.9; 95% CI: 1.1-3.5). Data analysis of child morbidity included 154 children who received the IHIP intervention (individually and combined with ECD) and 156 controls. We recorded 110,666 child-days of information on diarrhoea morbidity and observed 1.3 mean episodes per child-year in the children who received the IHIP intervention and 1.1 episodes in the controls. This corresponded to an incidence risk ratio of 1.2 (95% CI: 0.8-1.7). CONCLUSIONS: Child stimulation improved developmental status in children, but there was no health benefit associated with the home-environmental intervention. Limited year-round access to running water at home and the possible contamination of drinking water after boiling were two potential factors linked to the lack of effect of the home-environmental intervention. Potential interactions between ECD and home-environmental interventions need to be further investigated. TRIAL REGISTRATION: ISRCTN, ISRCTN-26548981.
