SLESIS-R: an improved score for prediction of serious infection in patients with systemic lupus erythematosus based on the RELESSER prospective cohort.

OBJECTIVE: To develop an improved score for prediction of severe infection in patients with systemic lupus erythematosus (SLE), namely, the SLE Severe Infection Score-Revised (SLESIS-R) and to validate it in a large multicentre lupus cohort. METHODS: We used data from the prospective phase of RELESSER (RELESSER-PROS), the SLE register of the Spanish Society of Rheumatology. A multivariable logistic model was constructed taking into account the variables already forming the SLESIS score, plus all other potential predictors identified in a literature review. Performance was analysed using the C-statistic and the area under the receiver operating characteristic curve (AUROC). Internal validation was carried out using a 100-sample bootstrapping procedure. ORs were transformed into score items, and the AUROC was used to determine performance. RESULTS: A total of 1459 patients who had completed 1 year of follow-up were included in the development cohort (mean age, 49±13 years; 90% women). Twenty-five (1.7%) had experienced ≥1 severe infection. According to the adjusted multivariate model, severe infection could be predicted from four variables: age (years) ≥60, previous SLE-related hospitalisation, previous serious infection and glucocorticoid dose. A score was built from the best model, taking values from 0 to 17. The AUROC was 0.861 (0.777-0.946). The cut-off chosen was ≥6, which exhibited an accuracy of 85.9% and a positive likelihood ratio of 5.48. CONCLUSIONS: SLESIS-R is an accurate and feasible instrument for predicting infections in patients with SLE. SLESIS-R could help to make informed decisions on the use of immunosuppressants and the implementation of preventive measures.

Microneedle-mediated Delivery of Immunomodulators Restores Immune Privilege in Hair Follicles and Reverses Immune-Mediated Alopecia.

Disorders in the regulatory arm of the adaptive immune system result in autoimmune-mediated diseases. While systemic immunosuppression is the prevailing approach to manage them, it fails to achieve long-lasting remission due to concomitant suppression of the regulatory arm and carries the risk of heightened susceptibility to infections and malignancies. Alopecia Areata is a condition characterized by localized hair loss due to autoimmunity. The accessibility of the skin provides an opportunity for local rather than systemic intervention to avoid broad immunosuppression. We hypothesized that expansion of endogenous regulatory T cells (Tregs) at the site of antigen encounter can restore the immune balance and generate a long-lasting tolerogenic response. We therefore utilized a hydrogel microneedle (MN) patch for delivery of CCL22, a chemoattractant for Tregs, and IL-2, a Treg survival factor to amplify them. In an immune-mediated murine model of alopecia, we showed local bolstering of Treg numbers leading to sustained hair regrowth and attenuation of inflammatory pathways. In a humanized skin transplant mouse model, we confirmed expansion of Tregs within human skin without engendering peripheral immunosuppression. The MN patch offered high-loading capacity and shelf-life stability for prospective clinical translation. By harmonizing immune responses locally, we aspire to reshape the landscape of autoimmune skin disease management. This article is protected by copyright. All rights reserved.

Afamitresgene autoleucel for advanced synovial sarcoma and myxoid round cell liposarcoma (SPEARHEAD-1): an international, open-label, phase 2 trial.

BACKGROUND: Afamitresgene autoleucel (afami-cel) showed acceptable safety and promising efficacy in a phase 1 trial (NCT03132922). The aim of this study was to further evaluate the efficacy of afami-cel for the treatment of patients with HLA-A*02 and MAGE-A4-expressing advanced synovial sarcoma or myxoid round cell liposarcoma. METHODS: SPEARHEAD-1 was an open-label, non-randomised, phase 2 trial done across 23 sites in Canada, the USA, and Europe. The trial included three cohorts, of which the main investigational cohort (cohort 1) is reported here. Cohort 1 included patients with HLA-A*02, aged 16-75 years, with metastatic or unresectable synovial sarcoma or myxoid round cell liposarcoma (confirmed by cytogenetics) expressing MAGE-A4, and who had received at least one previous line of anthracycline-containing or ifosfamide-containing chemotherapy. Patients received a single intravenous dose of afami-cel (transduced dose range 1·0 × 109-10·0 × 109 T cells) after lymphodepletion. The primary endpoint was overall response rate in cohort 1, assessed by a masked independent review committee using Response Evaluation Criteria in Solid Tumours (version 1.1) in the modified intention-to-treat population (all patients who received afami-cel). Adverse events, including those of special interest (cytokine release syndrome, prolonged cytopenia, and neurotoxicity), were monitored and are reported for the modified intention-to-treat population. This trial is registered at ClinicalTrials.gov, NCT04044768; recruitment is closed and follow-up is ongoing for cohorts 1 and 2, and recruitment is open for cohort 3. FINDINGS: Between Dec 17, 2019, and July 27, 2021, 52 patients with cytogenetically confirmed synovial sarcoma (n=44) and myxoid round cell liposarcoma (n=8) were enrolled and received afami-cel in cohort 1. Patients were heavily pre-treated (median three [IQR two to four] previous lines of systemic therapy). Median follow-up time was 32·6 months (IQR 29·4-36·1). Overall response rate was 37% (19 of 52; 95% CI 24-51) overall, 39% (17 of 44; 24-55) for patients with synovial sarcoma, and 25% (two of eight; 3-65) for patients with myxoid round cell liposarcoma. Cytokine release syndrome occurred in 37 (71%) of 52 of patients (one grade 3 event). Cytopenias were the most common grade 3 or worse adverse events (lymphopenia in 50 [96%], neutropenia 44 [85%], leukopenia 42 [81%] of 52 patients). No treatment-related deaths occurred. INTERPRETATION: Afami-cel treatment resulted in durable responses in heavily pre-treated patients with HLA-A*02 and MAGE-A4-expressing synovial sarcoma. This study shows that T-cell receptor therapy can be used to effectively target solid tumours and provides rationale to expand this approach to other solid malignancies. FUNDING: Adaptimmune.

Impact of SARS-CoV-2 vaccines and recent chemotherapy on COVID-19 morbidity and mortality in patients with soft tissue sarcoma: an analysis from the OnCovid registry.

Background: To date, limited evidence exists on the impact of COVID-19 in patients with soft tissue sarcoma (STS), nor about the impact of SARS-CoV-2 vaccines and recent chemotherapy on COVID-19 morbidity and mortality in this specific population. Methods: We described COVID-19 morbidity and mortality among patients with STS across 'Omicron' (15 December 2021-31 January 2022), 'Pre-vaccination' (27 February 2020-30 November 2020), and 'Alpha-Delta' phase (01 December 2020-14 December 2021) using OnCovid registry participants (NCT04393974). Case fatality rate at 28 days (CFR28) and COVID-19 severity were also described according to the SARS-CoV-2 vaccination status, while the impact of the receipt of cytotoxic chemotherapy within 4 weeks prior to COVID-19 on clinical outcomes was assessed with Inverse Probability of Treatment Weighting (IPTW) models adjusted for possible confounders. Results: Out of 3820 patients, 97 patients with STS were included. The median age at COVID-19 diagnosis was 56 years (range: 18-92), with 65 patients (67%) aged < 65 years and most patients had a low comorbidity burden (65, 67.0%). The most frequent primary tumor sites were the abdomen (56.7%) and the gynecological tract (12.4%). In total, 36 (37.1%) patients were on cytotoxic chemotherapy within 4 weeks prior to COVID-19. The overall CFR28 was 25.8%, with 38% oxygen therapy requirement, 34% rate of complications, and 32.3% of hospitalizations due to COVID-19. CFR28 (29.5%, 21.4%, and 12.5%) and all indicators of COVID-19 severity demonstrated a trend toward a numerical improvement across the pandemic phases. Similarly, vaccinated patients demonstrated numerically improved CFR28 (16.7% versus 27.7%) and COVID-19 morbidity compared with unvaccinated patients. Patients who were on chemotherapy experienced comparable CFR28 (19.4% versus 26.0%, p = 0.4803), hospitalizations (50.0% versus 44.4%, p = 0.6883), complication rates (30.6% versus 34.0%, p = 0.7381), and oxygen therapy requirement (28.1% versus 40.0%, p = 0.2755) compared to those who were not on anticancer therapy at COVID-19, findings further confirmed by the IPTW-fitted multivariable analysis. Conclusion: In this study, we demonstrate an improvement in COVID-19 outcomes in patients with STS over time. Recent exposure to chemotherapy does not impact COVID-19 morbidity and mortality and SARS-CoV-2 vaccination confers protection against adverse outcomes from COVID-19 in this patient population.

An analysis from the OnCovid registry on the impact of chemotherapy and SARS-CoV-2 vaccines on clinical outcomes of patients with soft tissue sarcoma and COVID-19 Soft tissue sarcomas (STS) are a group of rare and aggressive tumours, usually treated with high dose cytotoxic chemotherapy. To date no clear evidence exists on the impact of COVID-19 in patients with STS, nor on the potential impact of recent chemotherapy and prior SARS-CoV-2 vaccination in this specific patient population. This is the 1st study to show COVID-19 outcomes in patients with STS, highlighting a substantial vaccine efficacy with no negative impact of recent chemotherapy on COVID-19 outcomes.

Honduras HIV cohort: HLA class I and CCR5-Δ32 profiles and their associations with HIV disease outcome.

IMPORTANCE: We identify both canonical and novel human leukocyte antigen (HLA)-HIV associations, providing a first step toward improved understanding of HIV immune control among the understudied Honduras Mestizo population. Our results are relevant to understanding the protective or detrimental effects of HLA subtypes in Latin America because their unique HLA diversity poses challenges for designing vaccines against HIV and interpreting results from such vaccine trials. Likewise, the description of the HLA profile in an understudied population that shows a unique HLA immunogenetic background is not only relevant for HIV immunology but also relevant in population genetics, molecular anthropology, susceptibility to other infections, autoimmune diseases, and allograft transplantation.

Sleep and Perceived Stress: An Exploratory Mediation Analysis of the Role of Self-Control and Resilience among University Students.

BACKGROUND: High levels of stress are frequent in university education, and a lack of sleep has been reported to make students more vulnerable to stress. The mechanisms through which sleep harms students have not been sufficiently clarified; therefore, this study aimed to explore the mediating role of self-control and resilience in the relationship between sleep quality and duration and perceived stress. METHODS: Of 32 first-year college students, 21 (78%) were women, with a mean age of 18.47 (±0.84). They responded to a self-administered survey that included questions on stress, resilience, and sleep quality and recorded their daily sleep duration using a wristband for six days. RESULTS: Perceived stress was significantly correlated with resilience (r = -0.63), self-control (r = -0.46), sleep duration (r = -0.35), and lower sleep quality (r = 0.57). Path analysis revealed that self-control and resilience were partially mediated by sleep quality (R2 = 0.62; p < 0.01) and completely mediated by sleep duration (R2 = 0.46; p < 0.01). In both models, self-control had a direct effect on resilience and had a good-fit index. CONCLUSION: Being resilient seems to play a mediating role in the relationship between sleep and perceived stress; this ability can be favored by self-control, which is directly influenced by sleep.

Increased incidence of rheumatoid arthritis after COVID-19.

An increase in the incidence of inflammatory arthritis after COVID-19 has been reported. Since many diseases exhibit population-specific causal effect sizes, we aimed to evaluate the incidence trends of inflammatory arthritis, including rheumatoid arthritis (RA), after COVID-19 in a large admixed Colombian population. Data analysis for this retrospective, population-based cohort study was carried out using the COOSALUD EPS registry. The following codes were selected for analyses: M059, seropositive RA, M069, unspecified RA, M060 seronegative RA, and other RA-related diagnoses: M064, M139, M068, M058, M130 and M053. The study period was limited to January 01, 2018, through December 31, 2022. Incidence rates (IRs) and incidence rate ratios (IRRs) were assessed. A Cox survival model was built to evaluate the influence of age, gender, and COVID-19 vaccination status on the development of inflammatory arthritis. A bioinformatic analysis was performed to evaluate the homology between SARS-CoV-2 and autoantigen peptides related to RA. The entire population study comprised 3,335,084 individuals. During the pandemic period (2020-2022) the total IIR for seropositive and unspecified RA were 1.60 (95% CI, 1.16-2.22) and 2.93 (95% CI, 2.04-4.19), respectively, and the IIR for overall RA-related diagnosis was 2.01 (95% CI 1.59-2.53). The age groups hazard ratios (HRs) were increased until the age group of 51-60 years (HR: 9.16; 95% CI, 7.24-11.59) and then decreased slightly in the age group 61 years or older (HR: 5.364; 95% CI, 4.24-6.78) compared to those within 18-30 years. Men were less at risk than women to develop inflammatory arthritis (HR: 0.21; 95% CI, 0.18-0.24). The greater time since COVID-19 diagnosis was associated with a lower likelihood of developing inflammatory arthritis (HR: 0.99; 95% CI:0.998-0.999). Vaccination (all types of COVID-19 vaccines included) did not prevent the development of inflammatory arthritis after COVID-19. Low identity was found between the SARS-CoV-2 ORF1ab antigen and the human antigens Poly ADP-ribose polymerase 14 and Protein mono-ADP-ribosyltransferase PARP9 isoform D (39% and 29%, respectively). In conclusion, our study confirms increased incidence of inflammatory arthritis, including RA, after COVID-19, with the greatest increase occurring before the first year post-covid. Women in their fifties were more susceptible. Further research is required to examine the effectiveness of vaccination in preventing post-COVID inflammatory arthritis and the mechanisms implicated in the development of RA after COVID-19.

Skin fragility in a cat presenting with pituitary-dependent hyperadrenocorticism.

Case summary: A case of skin fragility in an 8-year-old domestic shorthair cat with pituitary-dependent hyperadrenocorticism is described. The cat was referred to the Feline Centre at Langford Small Animal Hospital with a 2-month history of multiple skin wounds with no known traumatic aetiology. A low-dose dexamethasone suppression test was performed before referral, which was consistent with hyperadrenocorticism. On presentation, the cat had multiple cutaneous lacerations and patchy areas of alopecia. CT was performed, which revealed a pituitary mass most consistent with pituitary-dependent hyperadrenocorticism. Treatment with oral trilostane (Vetoryl; Dechra) was commenced and clinical improvement was observed; however, further extensive skin lesions as a consequence of her skin fragility resulted in euthanasia. Relevance and novel information: Hyperadrenocorticism is an uncommon endocrinopathy of cats; however, it is an important differential for skin thinning and non-healing wounds. Skin fragility remains an important factor in the consideration of appropriate treatment protocols and ongoing quality of life in these patients.

Updated Review and Clinical Recommendations for the Diagnosis and Treatment of Patients with Retroperitoneal Sarcoma by the Spanish Sarcoma Research Group (GEIS).

Soft tissue sarcomas (STS) are an uncommon and biologically heterogeneous group of tumors arising from mesenchymal cells. The incidence is estimated at five cases per 100,000 people per year. Retroperitoneal sarcomas (RPS) account for 10-15% of all STS, and their management depends on their anatomical characteristics and histotype. Due to their very low incidence, it is recommended that RPS be treated in reference centers and evaluated by an experienced multidisciplinary team (MDT). In Spain, the Spanish Group for Research in Sarcomas (GEIS) brings together experts from various specialties to promote research on sarcomas and improve treatment results. This paper summarizes the GEIS recommendations for the diagnosis, treatment, and follow-up of patients with RPS.

Atrophic violaceous plaques as the first manifestation of a disorder of GNAS inactivation.

We report the case of a 10-month-old girl who presented with failure to thrive and multiple small atrophic violaceous plaques, with no other findings on her physical examination. The laboratory examinations, abdominal ultrasound and bilateral hand radiography performed were unremarkable. The skin biopsy revealed fusiform cells and focal ossification in the deep dermis. The genetic study showed a pathogenic variant of GNAS.

Clinical Factors, Management, and Outcomes of Patients Under 18 Years Old With Central Nervous System Tumors: Single-center Experience in Peru.

Few reports on clinical factors, treatment, and survival in children and adolescents with Central nervous system tumors in low-income and middle-income countries in Latin America exist. We retrospectively reviewed such data in all cases of patients younger than 18 years with brain tumors diagnosed in a single tertiary care center in Peru from 2007 through 2017. Variables were analyzed for association with overall survival and event-free survival by using the Kaplan-Meier method and the Cox hazards ratio regression. Seventy-five patients' data were analyzed (40 boys, 35 girls; mean age=7.7 y). The main clinical symptoms were headache, vomiting, difficulty walking, and visual disturbances. The most frequent clinical signs were hydrocephalus, cerebellar signs, visual abnormalities, and focal motor signs. The median time to diagnosis was 12 weeks. Tumor resection was performed in 68 patients, and 37 patients received postoperative radiotherapy. The most frequent histologic subtypes were low-grade gliomas and medulloblastomas. Overall survival rates at 1 and 5 years of disease were 78% (CI 95%, 0.67 to 0.86) and 74% (CI 95%, 0.62 to 0.82), respectively, and the 5-year event-free survival rate was 62% (CI 95%, 0.47 to 0.73). Although diagnosis occurred late in our cohort, the survival rate was higher than that in other Latin American countries.

HIV Drug Resistance in Adults Initiating or Reinitiating Antiretroviral Therapy in Uruguay-Results of a Nationally Representative Survey, 2018-2019.

The first nationally representative cross-sectional HIV drug resistance (HIVDR) survey was conducted in Uruguay in 2018-2019 among adults diagnosed with HIV and initiating or reinitiating antiretroviral therapy (ART). Protease, reverse transcriptase, and integrase genes of HIV-1 were sequenced. A total of 206 participants were enrolled in the survey; 63.2% were men, 85.7% were >25 years of age, and 35.6% reported previous exposure to antiretroviral (ARV) drugs. The prevalence of HIVDR to efavirenz or nevirapine was significantly higher (OR: 1.82, p < 0.001) in adults with previous ARV drug exposure (20.3%, 95% CI: 18.7-22.0%) compared to adults without previous ARV drug exposure (12.3%, 11.0-13.8%). HIVDR to any nucleoside reverse transcriptase inhibitors was 10.3% (9.4-11.2%). HIVDR to ritonavir-boosted protease inhibitors was 1.5% (1.1-2.1%); resistance to ritonavir-boosted darunavir was 0.9% (0.4-2.1%) among adults without previous ARV drug exposure and it was not observed among adults with previous ARV drug exposure. Resistance to integrase inhibitors was 12.7% (11.7-13.8%), yet HIVDR to dolutegravir, bictegravir, and cabotegravir was not observed. The high level (>10%) of HIVDR to efavirenz highlights the need to accelerate the transition to the WHO-recommended dolutegravir-based ART. Access to dolutegravir-based ART should be prioritised for people reporting previous ARV drug exposure.

A case of Rothmund-Thomson syndrome originally thought to be a case of Bloom syndrome.

Rothmund-Thomson syndrome, a heterogeneous genodermatosis with autosomal recessive hereditary pattern, is an uncommon cancer susceptibility genetic syndrome. To date, only 400 cases have been reported in the literature, and the severity of the features varies among individuals with the condition. Here, we describe a 55-year-old male who had been diagnosed with Bloom Syndrome during childhood due to the suggestive physical features such as short stature, chronic facial erythema, poikiloderma in face and extremities, microtia and microcephaly. However, the genetic test demonstrated that the patient carried two pathogenic variants resulting in compound heterozygous in the RECQL4 gene (c.2269C>T and c.2547_2548delGT). He subsequently developed a calcaneal osteosarcoma, which was successfully treated, and has currently been oncologic disease-free for 3 years.

Return to work in head and neck cancer survivors: a systematic review.

PURPOSE: Cancer survivors face higher rates of unemployment compared with individuals without a history of cancer. Compared to other cancer types, head and neck cancer (HNC) survivors face unique disease and treatment-specific issues that may limit return to work (RTW). This review aimed to determine employment outcomes of HNC survivors post-treatment and identify factors associated with RTW. METHODS: A systematic search was conducted in MEDLINE, CINAHL and PsycINFO in December 2021. Inclusion criteria included adults (≥ 18 years); completed treatment for HNC; data available on RTW post-treatment. Both quantitative and qualitative studies were considered. Studies were critically appraised and data synthesised narratively. RESULTS: Twenty-nine publications were included: 22 quantitative, four qualitative and three mixed methods. The proportion of HNC survivors who RTW ranged from 32 to 90%, with participants taking 3.6-11 months to RTW. Working in a professional role and having a supportive work environment were positively associated with RTW. CONCLUSIONS: The proportion of HNC survivors who RTW varies significantly which may be due to the heterogeneity between the studies including difference in clinical characteristics of the participants and/or sample size. Future studies that are longitudinal, adequately powered and measure a range of clinical and demographic variables are needed to better understand the RTW experience and assist development of effective RTW strategies. IMPLICATIONS FOR CANCER SURVIVORS: This review suggests potential areas for intervention, including enhanced symptom management and engaging with employers to foster supportive work environments to support RTW of HNC survivors.

Results of a survey on the treatment of adolescents and young adult (AYA) sarcoma patients in Spain at present time

Introduction We aimed to analyse health care services for adolescents and young adults (AYA) with sarcomas in Spain. Methods A survey was sent to all Spanish cancer centres, including questions about demographic, facilities, and treatment strategies for AYAs with sarcomas in the last 2 years. Results Thirty-five units participated in the survey, 17 paediatric and 15 adult units. There were three specialized AYA units. First line regimen varied depending on whether the treating unit was paediatric or not, for osteosarcomas, rhabdomyosarcomas, and non-rhabdomyosarcomas. By contrast, 91.4% of Ewing sarcomas were treated according to EE2012. In the relapse setting, differences between units were higher in all tumours. Additionally, 48% of the units reported not having trials for this population. Conclusion There are major differences in the treatment of AYAs with sarcomas between adult and paediatric units. Enormous efforts are needed to homogenize treatments and increase the access to innovation. (AU)

Violencia estatal y movimientos sociales mapuche: pichikeche violentados, una rebelión incubada / State violence and Mapuche social movements: violence committed against pichikeche in an incubated rebellion / Violência estatal e movimentos sociais Mapuche: atacou pichikeche, uma rebelião incubada

Resumen (analítico) El Estado chileno ha ejercido violencia contra el pueblo mapuche por generaciones, promoviendo la construcción de imaginarios en pichikeche (niños y niñas), lo que impacta en la expresión política de los movimientos sociales. Para analizar dicho impacto se usó una metodología cualitativa con diseño etnográfico. Los datos se obtuvieron mediante observación participante, entrevistas y dibujos. Participaron pichikeche de 5 a 12 años de edad, pertenecientes a cinco familias mapuche, respaldados por loncos (dirigentes) de su comunidad. Los resultados muestran que los imaginarios de dolor e incomprensión frente a la violencia, racismo y crueldad por parte del Estado pueden promover la generación de movimientos sociales que incluyen respuestas similares en colectivos de personas que carecieron de estrategias para la contención y resignificación de tales eventos traumáticos. A esto se le denomina «rebelión incubada¼.

Abstract (analytical) The Chilean State has committed violence against the Mapuche people for generations, promoting Mapuche children's construction of imaginary realities. This situation has an impact on the political expression of social movements. A qualitative methodology based on an ethnographic design was used. Data generation techniques included participant observation, interviews and pichikeche's drawings. The participants in this study were pichikeche (children) between 5 and 12 years of age from five Mapuche families supported by loncos (leaders) from their community. The results suggest that imaginary pain and misunderstanding caused by excessive and unjustified violence, racism and cruelty carried out by the State against Mapuche communities has promoted the generation of social movements. This could provoke a similar response among people who lack strategies for the containment and defining of these traumatic events, which is known as an incubated rebellion.

High Level of Pretreatment and Acquired Human Immunodeficiency Virus Drug Resistance in El Salvador: A Nationally Representative Survey, 2018-2019.

Background: Human immunodeficiency virus drug resistance (HIVDR) can negatively impact the effectiveness of antiretroviral therapy (ART). We aimed to estimate the prevalence of pretreatment HIVDR (PDR) among ART initiators and the prevalence of viral load (VL) suppression and acquired HIVDR among individuals receiving ART for 12 ± 3 months (ADR12) and ≥48 months (ADR48) in El Salvador. Methods: Nationally representative cross-sectional PDR, ADR12 and ADR48 surveys were conducted among adults with HIV from October 2018 to August 2019, following World Health Organization-recommended methods. Demographic and clinic data and blood specimens were collected. Results: Two hundred sixty participants were enrolled in the PDR survey, 230 in ADR12 and 425 in ADR48. Twenty-seven percent (95% confidence interval [CI], 17.1%-39.9%) of ART initiators had PDR to efavirenz or nevirapine. The prevalence of VL suppression was 88.8% (95% CI, 83.1%-92.8%) in ADR12 and 80.5% (95% CI, 76.6%-84.0%) in ADR48 surveys. Among people with HIV receiving a first-line nonnucleoside reverse transcriptase inhibitor (NNRTI)-based ART regimens and with unsuppressed VL, the prevalence of ADR to efavirenz or nevirapine was 72.0% (95% CI, 32.3%-93.3%) and 95.0% (68.5%-99.4%) in the ADR12 and ADR28 surveys, respectively. ADR12 to boosted protease inhibitors (PI/r) or integrase strand transfer inhibitors (INSTIs) was not observed. ADR48 was 1.3% (95% CI, 0.2%-9.6%) and 2.1% (0.3%-13.7%), respectively. Conclusions: Programmatic improvements in ART delivery are urgently needed in El Salvador to address the high levels of resistance to efavirenz or nevirapine among ART initiators and the low VL suppression prevalence among individuals on treatment.

Model for regional collaboration: Successful strategy to implement a pediatric early warning system in 36 pediatric oncology centers in Latin America.

BACKGROUND: Pediatric early warning systems (PEWS) aid in the early identification of deterioration in hospitalized children with cancer; however, they are under-used in resource-limited settings. The authors use the knowledge-to-action framework to describe the implementation strategy for Proyecto Escala de Valoracion de Alerta Temprana (EVAT), a multicenter quality-improvement collaborative, to scale-up PEWS in pediatric oncology centers in Latin America. METHODS: Proyecto EVAT mentored participating centers through an adaptable implementation strategy to: (1) monitor clinical deterioration in children with cancer, (2) contextually adapt PEWS, (3) assess barriers to using PEWS, (4) pilot and implement PEWS, (5) monitor the use of PEWS, (6) evaluate outcomes, and (7) sustain PEWS. The implementation outcomes assessed included the quality of PEWS use, the time required for implementation, and global program impact. RESULTS: From April 2017 to October 2021, 36 diverse Proyecto EVAT hospitals from 13 countries in Latin America collectively managing more than 4100 annual new pediatric cancer diagnoses successfully implemented PEWS. The time to complete all program phases varied among centers, averaging 7 months (range, 3-13 months) from PEWS pilot to implementation completion. All centers ultimately implemented PEWS and maintained high-quality PEWS use for up to 18 months after implementation. Across the 36 centers, more than 11,100 clinicians were trained in PEWS, and more than 41,000 pediatric hospital admissions had PEWS used in their care. CONCLUSIONS: Evidence-based interventions like PEWS can be successfully scaled-up regionally basis using a systematic approach that includes a collaborative network, an adaptable implementation strategy, and regional mentorship. Lessons learned can guide future programs to promote the widespread adoption of effective interventions and reduce global disparities in childhood cancer outcomes. LAY SUMMARY: Pediatric early warning systems (PEWS) are clinical tools used to identify deterioration in hospitalized children with cancer; however, implementation challenges limit their use in resource-limited settings. Proyecto EVAT is a multicenter quality-improvement collaborative to implement PEWS in 36 pediatric oncology centers in Latin America. This is the first multicenter, multinational study reporting a successful implementation strategy (Proyecto EVAT) to regionally scale-up PEWS. The lessons learned from Proyecto EVAT can inform future programs to promote the adoption of clinical interventions to globally improve childhood cancer outcomes.
