RESUMEN

In September 2020, the National Institutes of Health acted in response to the COVID-19 pandemic, recognizing the critical need to combat misinformation, particularly in communities disproportionately affected by the crisis. The Community Engagement Alliance (CEAL) emerged as an initiative dedicated to fostering reliable, science-based information, diversity, and inclusion; aiming to implement effective strategies to mitigate the spread of COVID-19 nationwide. One of the teams participating in this initiative is Puerto Rico-CEAL (PR-CEAL). Our whose goal was to raise awareness about the coronavirus disease and advance research, mainly focusing on vulnerable and underserved populations. This concept paper seeks to outline PR-CEAL's infrastructure during its initial two cycles, providing insights into the research and community engagement activities designed to enhance prevention, counter misinformation, and foster awareness and uptake of COVID-19 vaccines. Ultimately, our objective is to reflect on the strengths and challenges encountered thus far as we endeavor to sustain this robust infrastructure, addressing ongoing public health issues with a forward-looking approach.

RESUMEN

BACKGROUND: Education influences brain health and dementia. However, its impact across regions, specifically Latin America (LA) and the United States (US), is unknown. METHODS: A total of 1412 participants comprising controls, patients with Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD) from LA and the US were included. We studied the association of education with brain volume and functional connectivity while controlling for imaging quality and variability, age, sex, total intracranial volume (TIV), and recording type. RESULTS: Education influenced brain measures, explaining 24%-98% of the geographical differences. The educational disparities between LA and the US were associated with gray matter volume and connectivity variations, especially in LA and AD patients. Education emerged as a critical factor in classifying aging and dementia across regions. DISCUSSION: The results underscore the impact of education on brain structure and function in LA, highlighting the importance of incorporating educational factors into diagnosing, care, and prevention, and emphasizing the need for global diversity in research. HIGHLIGHTS: Lower education was linked to reduced brain volume and connectivity in healthy controls (HCs), Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD). Latin American cohorts have lower educational levels compared to the those in the United States. Educational disparities majorly drive brain health differences between regions. Educational differences were significant in both conditions, but more in AD than FTLD. Education stands as a critical factor in classifying aging and dementia across regions.

RESUMEN

BACKGROUND: Cervical cancer incidence is rising in Puerto Rico (PR). Whether the increase is real or reflective of increased diagnostic scrutiny remains unclear. METHODS: Using data from the PR Central Cancer Registry for 2001-2019, we estimated trends of hysterectomy-corrected cervical cancer incidence and mortality rates, overall, and by stage at diagnosis and age. RESULTS: Overall, cervical cancer incidence (per 100,000) increased 1.6%/year (95% CI, -0.5% to 3.8%) from 12.5 to 15.3, with a prominent increase in distant-stage disease (4.5%/year [95% CI, 1.6% to 8.0%]), particularly among screening age eligible (25-64-year-old) women (5.8%/year [95% CI, 2.1% to 10.6%]). Mortality rates in this age-group remained stable during the study period. CONCLUSIONS: Increased occurrence of distant-stage disease among screening-eligible women is troubling and may reflect a real increase. Future research is needed to elucidate the factors underlying these trends. Improved prevention is also an urgent priority to reverse the rising cervical cancer incidence in PR.

RESUMEN

Background: Persons living with HIV (PLWH) have a higher risk of persistent infection with human papillomavirus (HPV) and anal cancer. We evaluated knowledge and awareness of HPV infection and risk factors for anal cancer among PLWH in Puerto Rico (PR). Methods: Data from a cross-sectional study (2020-2021) were analyzed (n=212). Inclusion criteria included PLWH, aged ≥ 26 years, and living in PR. Telephone interviews collected information on sociodemographic, lifestyle and clinical characteristics. Two 13-item scales were used to assess knowledge of HPV and anal cancer risk factors; adequate knowledge for both scales were defined as scoring >70%. Logistic regression models using generalized linear models were used to determine the association between 1) HPV infection awareness, 2) HPV infection knowledge, and 3) Anal cancer risk factors knowledge. Results: The median age was 54 years (IQR: 46,58), 67.5% were male, 71.7% reported having an income <$20,000, and 54.3% had an education level of more than high school. HPV awareness was high (82.1%), but only 40.2% and 3.8% had adequate knowledge of HPV and anal cancer risk factors, respectively. In adjusted logistic regression models, men who have sex with men (OR: 1.26, 95%CI: 1.07-1.47) and women (OR: 1.35, 95%CI: 1.15-1.59) aged ≥50 years had higher odds of HPV awareness than heterosexual men in that age group. Moreover, those with history of anal Pap test aged <50 years had more HPV awareness (OR 1.34, 95%CI: 1.08-1.66) than their counterparts. Adequate HPV knowledge was higher among participants with an education level of more than high-school (OR:1.28, 95%CI: 1.10-1.50) and with a history of HPV diagnosis (OR:1.33, 95%CI: 1.08-1.65) than their counterparts. In addition, people with good/very good/excellent health perception had higher odds of HPV knowledge (OR:1.23, 95%CI: 1.03-1.47) than those who reported poor/regular health perception. For anal cancer risk factors, PLWH for ≥15 years had increased odds of having adequate knowledge (OR:1.07, 95%CI: 1.02-1.14) than their counterparts. Conclusions: Despite high awareness of HPV, limited knowledge about HPV and anal cancer risk factors was observed among PLWH. Results from our study highlight the need for educational efforts within this population as an anal cancer prevention strategy.

RESUMEN

Our objective was to determine the prevalence of cervical Pap screening among women living with HIV (WLWH) in Puerto Rico (P.R.) and other selected United States (U.S.) jurisdictions. Additionally, we sought to compare selected characteristics of WLWH who underwent cervical Pap screening between P.R. and the other U.S. jurisdictions. We analyzed data from the 2018-2021 cycles of CDC's Medical Monitoring Project (MMP), a national surveillance system among adults with HIV residing in P.R. (n = 218) and 22 other MMP jurisdictions (n = 3,653). Weighted percentages and 95 % confidence intervals (CIs) for selected characteristics were estimated. Prevalence ratios with predicted marginal means were calculated. An estimated 91.6 % and 84.6 % of WLWH underwent cervical Pap screening in P.R. and the other 22 MMP jurisdictions, respectively (Prevalence Ratio = 1.08, 95% CI = 1.03-1.13). Among WLWH who underwent cervical Pap screening, those in P.R. were more likely to be 50+ years of age, have a household annual income below $20,000, engage in binge drinking, never smoke, and have Medicaid/other public insurance than those in the other 22 MMP jurisdictions (p < 0.05). No differences were found between P.R. and the other 22 MMP jurisdictions in the percentage reporting higher than the median HIV-stigma score, experiencing HIV health care discrimination, and having ≥ 1 sexual partner in the past 12 months. Although cervical Pap screening rates among WLWH were higher in P.R. than in the other 22 MMP jurisdictions, both surpass the Healthy People 2030 target. Future research should assess adherence and compliance with updated cervical cancer screening guidelines.

RESUMEN

Objective: This study aimed to assess the association of body mass index (BMI) with anal high-risk human papillomavirus (HR-HPV) and biopsy-confirmed histologic anal high-grade squamous intraepithelial lesions (HSIL) among a clinic-based sample of Hispanics in Puerto Rico. Methods: This cross-sectional study evaluated medical records of adults who received services at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center between October 2014 and December 2022. The study included 543 records with complete clinical information regarding anal HR-HPV and anal HSIL status. Chi-square and logistic regression analyses were performed. Results: Mean age of participants was 44.10 ± 13.24 years, 65.2% were men, 71.7% were HIV-infected, 74.4% had anal HR-HPV infection, and 37.9% had biopsy-confirmed HSIL. Regarding BMI, 2.4% were underweight, 31.9% normal weight, and 39.0 % overweight; while 17.3 % had class I, 5.2% class II, and 4.2% class III obesity. No significant association was observed between BMI and anal HR-HPV infection in adjusted analyses. Lower odds of anal HSIL were observed among overweight individuals (OR: 0.63, 95% CI: 0.41 - 0.99) and those with class II/III obesity (OR: 0.48, 95% CI: 0.22 - 1.01) compared to adults with underweight/normal BMI, after adjusting for potential confounders. No significant association was observed for class I obesity. Conclusion: BMI was not associated with anal HR-HPV infection. Overweight and obese individuals had lower odds of having anal HSIL than adults with underweight/normal BMI. This finding could suggest underdiagnosis of HSIL among overweight/obese individuals, or reduced risk in this group.

RESUMEN

There is growing evidence about how physical activity can improve cancer care. Unfortunately, exercise is still not widely prescribed to oncology patients, despite the benefit it brings. For this to occur, it is necessary for a multidisciplinary approach involving different types of healthcare professionals, given that each treatment be tailored for each single case. Besides incorporating appropriate infrastructures and referral pathways, we need to integrate exercise into healthcare practice, which ameliorates patients' quality of life and treatment side effects. From the Spanish Society of Medical Oncology (SEOM), and through the Exercise and Cancer Working Group, we indicate considerations, analyze patient care scenarios, and propose a referral pathway algorithm for exercise prescription, taking in account the patient's needs. In later sections of this paper, we describe how this algorithm could be implemented, and how the exercise programs should be built, including the physical activity contents, the settings, and the delivery mode. We conclude that professionals, infrastructures, and organizations should be available at every assistance level to create programs providing adequate exercise training for cancer patients.

RESUMEN

OBJECTIVE: Cancer patients are among the most vulnerable populations during and after a disaster. We evaluated the impact of treatment interruption on the survival of women with gynecologic cancer in Puerto Rico following Hurricanes Irma and María. METHODS: A retrospective cohort study among a clinic-based sample of women with gynecological cancer diagnosed between January 2016 and September 2017 (n = 112) was done. Women were followed from their diagnosis until December 2019, to assess vital status. Kaplan-Meier survival curves and Cox proportional hazards models were performed. RESULTS: Mean age was 56 (± 12.3) years; corpus uteri (58.9%) was the most common gynecologic cancer. Predominant treatments were surgery (91.1%) and chemotherapy (44.6%). Overall, 75.9% were receiving treatment before the hurricanes, 16.1% experienced treatment interruptions, and 8.9% died during the follow-up period. Factors associated with treatment interruption in bivariate analysis included younger age (≤55 years), having regional/distant disease, and receiving > 1 cancer treatment (P < 0.05). Crude analysis revealed an increased risk of death among women with treatment interruption (HR: 3.88, 95% CI: 1.09-13.77), persisting after adjusting for age and cancer stage (HR: 2.49, 95% CI: 0.69-9.01). CONCLUSIONS: Findings underscore the detrimental impact of treatment interruption on cancer survival in the aftermath of hurricanes, emphasizing the need for emergency response plans for this vulnerable population.

RESUMEN

Caribbean small island developing states are becoming increasingly vulnerable to compounding disasters, prominently featuring climate-related hazards and pandemic diseases, which exacerbate existing barriers to cancer control in the region. We describe the complexities of cancer prevention and control efforts throughout the Caribbean small island developing states, including the unique challenges of people diagnosed with cancer in the region. We highlight potential solutions and strategies that concurrently address disaster adaptation and cancer control. Because Caribbean small island developing states are affected first and worst by the hazards of compounding disasters, the innovative solutions developed in the region are relevant for climate mitigation, disaster adaptation, and cancer control efforts globally. In the age of complex and cascading disaster scenarios, developing strategies to mitigate their effect on the cancer control continuum, and protecting the health and safety of people diagnosed with cancer from extreme events become increasingly urgent. The equitable development of such strategies relies on collaborative efforts among professionals whose diverse expertise from complementary fields infuses the local community perspective while focusing on implementing solutions.

RESUMEN

INTRODUCTION: Huntington's disease (HD) is a genetic neurodegenerative disorder with dominant inheritance. Our center in Mexico City has offered presymptomatic testing (PT) since 1995. OBJECTIVE: To describe the main clinical and demographic characteristics of at-risk HD individuals who applied to the PT program, the reasons for seeking it, and the molecular results. METHODS: A cross-sectional study was conducted with sociodemographic and clinical data of all PT applicants from 1995-2023. Reasons for seeking PT were assessed using a modified questionnaire. In addition, anxiety, and depressive symptoms before and after PT were evaluated with Beck's instruments; cognitive impairment (CI) was assessed with the Mini-Mental State Examination (MMSE) and molecular results. RESULTS: 214 people applied for PT (2.1% of the at-risk population identified in our center); 63% were women (mean age of 37.11 years). 204 (95.3%) were accepted and 190 received results. 70% indicated that the main reason for applying for PT was to inform their offspring about the risk of inheriting HD. Significant differences were observed in the reasons for seeking PT by age group. Although some subjects received treatment, Beck's instrument scores did not indicate special attention or pharmacological treatment. The MMSE showed probable CI in 20 subjects. Of those who received results, 37% were carriers of a full penetrance allele. CONCLUSION: Our center has the only formal PT program for HD in Mexico. The reasons for seeking PT are varied and age-related. Although PT is offered to all subjects at risk for HD, uptake remains low.

RESUMEN

Background: Fungi are a major component of the human microbiome that only recently received attention. The imbalance of indigenous fungal communities and environmental fungi present in the oral cavity may have a role in oral dysbiosis, which could exacerbate oral inflammatory diseases. Methods: We performed a cross-sectional study and recruited 88 participants aged 21 to 49 from sexually transmitted infection clinics in Puerto Rico. A full-mouth periodontal examination following the NHANES protocol defined periodontal severity (CDC/AAP). ITS2 (fungal) genes were amplified and sequenced for mycobiota characterization of yeast and environmental fungi. Environmental outdoor spore levels were measured daily by the American Academy of Allergy Asthma and Immunology San Juan station and defined by quartiles as spore scores. Results: Our data indicate polymicrobial colonization of yeast and environmental fungi in the oral cavity. Dominant taxa associated with periodontal disease included Saccharomyces cerevisiae, Rigidoporus vinctus, and Aspergillus penicilloides, while Candida albicans were found to be ubiquitous. Fungal aerosols were found to impact the oral cavity biofilm, likely due to competition and neutralization by inhaled outdoor and indoor fungal spores. Conclusion: To our knowledge, this is the first report showcasing the ecological competition of measured outdoor environmental fungi with the human oral mycobiota.

RESUMEN

BACKGROUND: Population-based information regarding the impact of respiratory syncytial virus (RSV) and influenza on hospital admissions and mortality is scant for many countries. METHODS: Prospective testing of RSV and influenza virus was undertaken in patients <5 years old admitted to hospital with acute respiratory infection (ARI) between July, 2014 and June, 2015, and mortality rates for children living in 3 municipalities in the state of San Luis Potosí were calculated. RESULTS: During the 12-month study period, 790 children living in these municipalities were admitted with ARI. RSV was detected in 245 (31%) and influenza in 47 (5.9%). History of preterm birth was recorded for 112 children on admission. For children <5 years old, ARI-, RSV- and influenza-associated admission rates were 23.2, 7.2 and 1.4 (per 1000 population), respectively. The corresponding admission rates per 1000 infants <1 year old were 78, 25.2 and 4.4. Preterm infant admission rates were 2 times higher than those of term infants. Six children died; RSV was detected in 4 (66.6%) of the deceased, while no deaths were associated with influenza. ARI and RSV in-hospital mortality rates for children <5 years were 0.18 and 0.12 per 1000 population. ARI and RSV mortality rates in preterm infants were 7 and 14 times higher than in term infants, respectively. CONCLUSIONS: RSV was associated with both high admission and in-hospital mortality rates in children <5 years old. Specific interventions, such as active or passive immunization, to prevent RSV infections are required to reduce ARI-associated infant mortality.

RESUMEN

Background: Limited research exists regarding the association between smoking and anal warts. In this study, we evaluated this association among a clinic-based Hispanic population in Puerto Rico. Methods: Cross-sectional study among eligible patients seen at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (2016-2023) (n = 920). Sociodemographic and clinical variables were collected from medical records. Patients underwent a high-resolution anoscopy (HRA) during the clinical visit; physicians assessed anal condylomas on HRA. Poisson regression models with robust standard errors were used to evaluate the association between smoking and anal warts. Demographic and clinical factors were also assessed. Results: The mean age of participants was 45.8 ± 13.1 years, 66.4 % were men, and 21.6 % were current smokers. While 10.8 % self-reported a history of anogenital condylomas, 18.9 % had anal condylomas on clinical evaluation. A higher prevalence of anal condylomas was observed among current smokers (PR = 1.28, 95 % CI: 0.94-1.75) in comparison to non-smokers in adjusted analysis, but this was not statistically significant. However, a higher prevalence of anal condylomas was observed among younger individuals (PR = 0.96, 95 % CI: 0.96-0.98) and individuals with anal high-grade squamous intraepithelial lesions (HSIL) as compared to those with benign histology (PR = 1.74. 95 % CI: 1.09-2.77). Conclusions: Although current smoking seemed to be positively associated with anal condylomas in this high-risk Hispanic population, this finding was not statistically significant as the power to detect an association was limited. However, younger age and HSIL diagnosis were associated with a higher prevalence of anal condylomas.

Material y Métodos: Estudio cualitativo fenomenológico hermenéutico, donde participaron mujeres adolescentes de 14 a 19 años, pertenecientes a la comunidad, El Molino, Ojuelos Jalisco, México. A través de un muestreo por cadena de referencia, se realizaron entrevistas fenomenológicas, transcritas de manera artesanal y anal-izadas mediante el "círculo hermenéutico Heiderggeriano". Se obtuvo la autorización mediante el consentimiento informado, así como el asentimiento por parte de los tutores. Se cumple un rigor metodológico a través de la trasparencia, transferibilidad, credibilidad y autenticidad. Resultados: Se realizaron 10 entrevistas afines a 10 adolescentes y se determinaron 6 unidades de significado a partir del análisis hermenéutico, de los cuales tres son ónticas; una realidad palpable a la desinformación sobre vida sexual, ideologías paternales adiestradas y falo centrismo como base central en la dinámica social. Y tres son ontológicas; Sesgo educativo, Discurso del lenguaje culturizado, finalmente tabúes y estigmas familiares. Conclusión: Las mujeres adolescentes de una comunidad rural viven una doble moral social. Así se demuestra un ineficiente conocimiento sobre salud sexual hasta ser un tema intrascendente, los padres son quienes influyen y toman decisiones sobre la educación, autonomía y forma de pensar.

Material and Methods: A qualitative hermeneutic phenomenological study, involving adolescent women from 14 to 19 years old, belonging to the community, El Molino Ojuelos Jalisco, México. Through a reference chain sampling, phenomenological inter-views were carried out, transcribed by hand and analyzed through the "Heiderggerian herme-neutic circle". Authorization was obtained through informed consent, as well as the assent of the tutors. Complying with methodological rigor through transparency, transferability, credibility and authenticity. Results: 10 related interviews were carried out with 10 adolescents, and 6 units of meaning were determined from the hermeneutic analysis, of which three are ontic; a palpable reality to the ignorance of contraceptive methods, trained paternal ideologies and phallocentrism as a central basis in social dynamics. And three are ontological; Educational bias, cultured language discourse, finally taboos and family stigmas. Conclusion: Adolescent women from a rural community experience a double social standard. Thus, demonstrating an inefficient knowledge about sexual health until it is an insignificant issue, parents are the ones who influence and make decisions about education, autonomy and way of thinking

RESUMEN

BACKGROUND: Anal cancer (AC) disproportionally affects people living with HIV (PLWH). Although there are no consensus-based AC screening guidelines, experts recommend anal pap as a primary screening tool in settings where high-resolution anoscopy (HRA) is available. We aimed to assess barriers and facilitators to anal cancer screening in a sample of Hispanic PLWH in Puerto Rico. METHODS: To assess their knowledge and attitudes, we conducted a cross-sectional survey from 2020-2021 among PLWH in Puerto Rico (n = 212). Data was collected through a telephone interview that assessed information on sociodemographics, knowledge, and attitudes about AC, and the history of AC screening. The chi-square test, Fisher exact test, and logistic regression models were used to assess factors associated with screening uptake. RESULTS: Anal Pap and HRA awareness were 60.4% and 30.7%, respectively. Anal Pap and HRA uptake was 51.5% and 19.3%, respectively. The most common barriers for anal Pap and HRA were lack of knowledge about the test and lack of physician recommendation. MSM were more likely to have heard of anal Pap (OR: 2.15, 95% CI:1.30-3.54) than MSW. MSM (OR: 3.04, 95% CI: 1.79-5.19) and women (OR: 3.00, 95% CI: 1.72-5.20) were also more likely to have undergone anal Pap. Similarly, individuals with a history of genital warts were more likely to have heard of anal Pap and HRA and have undergone anal Pap and HRA. Awareness of where to go for concerns about anal health was positively associated with having received anal Pap and HRA. CONCLUSIONS: With emerging evidence on the effectiveness of screening and treatment for anal cancer, several organizations are steering toward generating consensus-based anal cancer screening recommendations. Our study provides foundational data on barriers and facilitators to anal cancer screening in Puerto Rico that will be critical to informing screening implementation in this US territory.

RESUMEN

Introducción. A pesar de la importante presencia de la población haitiana en países de América Latina, existen pocos estudios que evalúen la salud mental en esta población; una de las razones es la falta de instrumentos psicométricos en kreyol (creole haitiano). Objetivo. Adaptar la versión en español de la Escala de Depresión del Centro de Estudios Epidemiológicos (CESD-R-20) al kreyol. Métodos. Estudio transversal de muestreo bietápico con 207 migrantes haitianos viviendo en Santiago de Chile, se tradujo y retrotradujo la Escala CESD-R-20 del español al kreyol. Resultados. 132 participantes respondieron la encuesta en kreyol y 75 en español. Las técnicas de detección de la dimensionalidad recomiendan retener un único componente y tres factores, con pocas excepciones a través de las muestras. Las soluciones factoriales llevan a retener un único factor, que presenta un Alfa de Cronbach =0.92 (IC: 0.90-0.94) adecuado. Estos resultados indican que se necesita un único factor. Discusión y conclusión. La adaptación del instrumento CESD-R-20 de español al kreyol obtiene evidencias de validez favorables y puede servir para iniciar nuevos estudios en población migrante haitiana en su trayecto por América Latina, si bien es necesario seguir ampliando el proceso de validación.

Introduction. Although the Haitian migrant population has a significant presence in Latin American countries, a few studies assess this population's mental health; one of the reasons is the lack of psychometric instruments in kreyol (Haitian Creole). Objective. Adapt the Spanish version of the Depression Scale of the Center for Epidemiological Studies (CESD-R-20) into kreyol. Methods. Based on a cross-sectional two-stage cluster sampling with 207 Haitian migrants living in Santiago de Chile, we conducted translation and back translation of the CESD-R-20 Scale from Spanish to kreyol; additionally, we reached an adapted version in Spanish. Results. In total, 132 participants answered the survey in Kreyol and 75 in Spanish. Dimensionality detection techniques recommend retaining a single component and three factors, with few exceptions across samples. Exploration of factor solutions leads to the retention of a single factor, which has an adequate Cronbach's alpha=0.92 (IC: 0.90;0.94). These results indicate that only one factor is needed. Discussion and conclusion. The adaptation of the Spanish CESD-R-20 instrument to Kreyol has obtained favorable validity evidence and can be used to initiate new studies on the Haitian migrant population on their journey through Latin America, although the validation process needs to be further extended.

RESUMEN

Objectives: To report the first Mexican case with two novel AARS2 mutations causing primary ovarian failure, uterus infantilis, and early-onset dementia secondary to leukoencephalopathy. Methods: Detailed clinical, clinimetric, neuroimaging features, muscle biopsy with biochemical assays of the main oxidative phosphorylation complexes activities, and molecular studies were performed on samples from a Mexican female. Results: We present a 41-year-old female patient with learning difficulties since childhood and primary amenorrhea who developed severe cognitive, motor, and behavioral impairment in early adulthood. Neuroimaging studies revealed frontal leukoencephalopathy with hypometabolism at the fronto-cerebellar cortex and caudate nucleus. Uterus infantilis was detected on ultrasound study. Clinical exome sequencing identified two novel variants, NM_020745:c.2864G>A (p.W955*) and NM_020745:c.1036C>A (p.P346T, p.P346Wfs*18), in AARS2. Histopathological and biochemical studies on muscle biopsy revealed mitochondrial disorder with cytochrome C oxidase (COX) deficiency. Conclusions: Several adult-onset cases of leukoencephalopathy and ovarian failure associated with AARS2 variants have been reported. To our best knowledge, none of them showed uterus infantilis. Here we enlarge the genetic and phenotypic spectrum of AARS2-related dementia with leukoencephalopathy and ovarian failure and contribute with detailed clinical, clinometric, neuroimaging, and molecular studies to disease and novel molecular variants characterization.

RESUMEN

BACKGROUND: Given the disproportionately elevated anal cancer risk in high-risk populations, it is important to assess the performance of commonly used anal cancer screening tools to improve the effectiveness of detection and treatment methods. This study evaluates 1) the concordance between anal cytology and histology results and 2) the performance of cytology and high-risk human papillomavirus (HR-HPV) genotyping as screening tools for detecting histologically confirmed anal high-grade squamous intraepithelial lesions (HSIL). METHODS: Data from the Anal Neoplasia Clinic in Puerto Rico (2014-2021; n = 466) was used. The clinical performance of anal cytology and HR-HPV genotyping to detect HSIL was compared to the gold standard: high-resolution anoscopy-guided biopsy. Sensitivity, specificity, positive predictive value, negative predictive value, and κ coefficients were calculated. RESULTS: A total of 66.95% of the patients were men, 74.0% were people living with HIV, 76.2% had anal HR-HPV infection, and 40.34% had histologically confirmed anal HSIL. The weighted κ statistic between the tests (cytology and histology) was 0.25 (p < .001). The sensitivity and specificity of cytology alone to detect anal HSIL were 84.3% (95% confidence interval [CI], 78.3%-89.1%) and 36.0% (95% CI, 30.3%-42.0%), respectively. Anal HR-HPV genotyping had higher sensitivity (92.2%; 95% CI, 87.4%-95.6%) and similar specificity (34.8%; 95% CI, 29.2%-40.7%) compared to cytology. The two tests combined (positive results following cytology or HR-HPV test) improved sensitivity to detect anal HSIL (97.9%; 95% CI, 94.8%-99.4%), but specificity was compromised (19.2%; 95% CI, 14.7%-24.4%). CONCLUSION: Although HR-HPV genotyping improved the detection of anal HSIL, HR-HPV testing had lower specificity than anal cytology alone.

RESUMEN

Prior to the COVID pandemic, Puerto Rico (PR) had one of the highest Human Papillomavirus (HPV) vaccine rates in the United States. The COVID pandemic and administration of COVID vaccines might have impacted attitudes toward HPV vaccination. This study compared attitudes toward HPV and COVID vaccines with respect to school-entry policies among adults living in PR. A convenience sample of 222 adults (≥21 years old) completed an online survey from November 2021 to January 2022. Participants answered questions about HPV and COVID vaccines, attitudes toward vaccination policies for school-entry, and perceptions of sources of information. We assessed the magnitude of association between the agreement of school-entry policies for COVID and HPV vaccination by estimating the prevalence ratio (PRadjusted) with 95% Confidence Intervals (95% CI). The most trusted source of information for HPV and COVID vaccines were healthcare providers (42% and 17%, respectively) and the CDC (35% and 55%, respectively), while the least trusted were social media (40% and 39%, respectively), and friends and family (23% n = 47, and 17% n = 33, respectively). Most participants agreed that HPV (76% n = 156) and COVID vaccines (69% n = 136) should be a school-entry requirement. Agreement with school policy requiring COVID vaccination was significantly associated with agreement of school policy requiring HPV vaccination (PRadjusted:1.96; 95% CI:1.48-2.61) after controlling for potential confounders. Adults living in PR have an overall positive attitude about mandatory HPV and COVID vaccination school-entry policies, which are interrelated. Further research should elucidate the implications of the COVID pandemic on HPV vaccine attitudes and adherence rates.
