RESUMO

The network interaction between systemic inflammatory mediators, endothelial cell adhesion function, and adiponectin as mediators of the association between metabolic diseases and periodontitis has not been evaluated. The objective of this study is to assess whether the interaction of baseline serum levels of TNF-α, hs-CRP, ICAM-1, VCAM-1, and adiponectin leads to periodontitis. Five hundred and ninety-seven overweight/obese (overweight: BMI 25 to <30 kg/m2; obese: >30 kg/m2) adults, aged 40-65 years, with complete 3-year follow-up data were included. Generalized structural equation models with negative binomial regression were used to estimate the regression coefficient (ß) for the outcome number of teeth with probing pocket depth (PPD) ≥ 4 mm and bleeding on probing (BOP) at 3-year follow-up for a 1 standard deviation unit increase (Δ = +1SD) in each biomarker. After adjusting for multiple covariates, baseline ICAM-1 and VCAM-1 had significant direct effects on increased log-transformed number of teeth with PPD ≥ 4 mm and BOP (ß: 0.16; 95% CI: 0.02-0.30; ß: 0.15; 95% CI: 0.02-0.30, respectively). Baseline hs-CRP showed a significant indirect effect via ICAM-1 on the log-transformed number of teeth with PPD ≥ 4 mm and BOP (ß: 4.84; 95% CI: 0.27-9.42). Thus, elevated serum ICAM-1 and VCAM-1 have a significant direct effect and increased hs-CRP has a significant indirect effect on the predicted level of periodontitis at the 3-year follow-up among overweight/obese Hispanic adults.

RESUMO

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.

RESUMO

In September 2017, Hurricane Maria devastated the Caribbean region, among them the US territory of Puerto Rico (PR). Vaccination distribution and uptake suffered from the impact. This study evaluated the trends in monthly vaccination initiation rates for human papilloma virus (HPV), Tdap and meningococcal conjugate (MenACWY) adolescent vaccines from 2015 to 2019, during which it was possible to observe and analyze the impact of Hurricane Maria on vaccine initiation. Monthly initiation rates were estimated. Age-standardized initiation rate ratio (SRR) and 95% CI were estimated. The analysis included 85,340 adolescents; 52.3% were male, and 47.7% were females. September 2017 showed HPV vaccine initiation had the lower rates of all the studied vaccines, with a rate of 75% after the disaster (from a rate of almost 90% in July 2017). Tdap and MenACWY vaccines rates remained above 90% in the same period. The SRR of HPV vaccine for September and October 2017 showed an estimated reduction of 5% and 8% in vaccine initiation rates, respectively for each month, when 2016 was the reference year (p > .05). The SRR of Tdap and MenACWY vaccines for November 2017 showed significant reductions when 2015 and 2016 were reference years (p < .05). HPV vaccine initiation rate was the most severely affected by the Hurricane Maria. Post-natural disaster protocols should strengthen existing programs for facilitate immunization access.

RESUMO

In 2018, Puerto Rico (PR) enacted a Human papillomavirus (HPV) vaccine school-entry requirement for students ages 11 to 12. Using the Consolidated Framework for Implementation Research (CFIR), we aimed to identify potential barriers and facilitators of this implementation. We conducted 38 qualitative interviews with stakeholders in PR from different organizations (Department of Health, Schools, Healthcare Providers, and Community organizations). We evaluated construct rating variability between the organizations to determine barriers and facilitators. The strongest facilitator determined was stakeholder's awareness of the parent's and student's needs to meet the HPV school-entry requirement. Other facilitators included initiatives for school-entry policies and the relative advantage of this requirement over different strategies. The strongest barriers included was the cost for private providers to administer the HPV vaccine, the negative influence of social media about the vaccine, which affected parents' acceptance, and the lack of school nurses as available staff resources for the school entry requirement. Findings from this study can be used to improve implementation (adaptations/modifications) and inform other states and countries in earlier stages of consideration of the adoption of similar immunization policies. Most barriers can be modifiable with the implementation of educational programs/training across schools, considering that they are the first line of response to parents of this school entry requirement.

RESUMO

The objectives of this analysis were to compare the ability of fasting plasma glucose (FPG), post oral load plasma glucose (2hPG), and hemoglobin A1c (HbA1c) to identify U.S. Hispanic/Latino individuals with prediabetes, and to assess its cardiovascular risk factor correlates. This is a cross-sectional analysis of baseline data from 15,507 adults without self-reported diabetes mellitus from six Hispanic/Latino heritage groups, enrolled in the Hispanic Community Health Study/Study of Latinos, which takes place in four U.S. communities. The prevalence of prediabetes was determined according to individual or combinations of ADA-defined cut points: FPG=5.6-7.0mmol/L, 2hPG=7.8-11.1mmol/L, and HbA1c=5.7%-6.4% (39-46mmol/mol). The sensitivity of these criteria to detect prediabetes was estimated. The prevalence ratios (PRs) for selected cardiovascular risk factors were compared among alternative categories of prediabetes versus normoglycemia [FPG<5.6mmol/L and 2hPG<7.8mmol/L and HbA1c<5.7% (39mmol/mol)]. Approximately 36% of individuals met any of the ADA prediabetes criteria. Using 2hPG as the gold standard, the sensitivity of FPG was 40.1%, HbA1c was 45.6%, and that of HbA1c+FPG was 62.2%. The number of significant PRs for cardiovascular risk factors was higher among individuals with isolated 2hPG=7.8-11.1mmol/L, FPG=5.6-7.0mmol/L+HbA1c=5.7%-6.4%, or those who met the three prediabetes criteria. Assessing FPG, HbA1c, and cardiovascular risk factors in Hispanics/Latinos at risk might enhance the early prevention of diabetes mellitus and cardiovascular complications in this young and growing population, independent of their heritage group.

RESUMO

OBJECTIVE: The aim of this study was to compare the ability of American Diabetes Association (ADA) diagnostic criteria to identify U.S. Hispanics/Latinos from diverse heritage groups with probable diabetes mellitus and assess cardiovascular risk factor correlates of those criteria. METHODS: Cross-sectional analysis of data from 15,507 adults from 6 Hispanic/Latino heritage groups, enrolled in the Hispanic Community Health Study/Study of Latinos. The prevalence of probable diabetes mellitus was estimated using individual or combinations of ADA-defined cut points. The sensitivity and specificity of these criteria at identifying diabetes mellitus from ADA-defined prediabetes and normoglycemia were evaluated. Prevalence ratios of hypertension, abnormal lipids, and elevated urinary albumin-creatinine ratio for unrecognized diabetes mellitus-versus prediabetes and normoglycemia-were calculated. RESULTS: Among Hispanics/Latinos (mean age, 43 years) with diabetes mellitus, 39.4% met laboratory test criteria for probable diabetes, and the prevalence varied by heritage group. Using the oral glucose tolerance test as the gold standard, the sensitivity of fasting plasma glucose (FPG) and hemoglobin A1c-alone or in combination-was low (18, 23, and 33%, respectively) at identifying probable diabetes mellitus. Individuals who met any criterion for probable diabetes mellitus had significantly higher (P<.05) prevalence of most cardiovascular risk factors than those with normoglycemia or prediabetes, and this association was not modified by Hispanic/Latino heritage group. CONCLUSION: FPG and hemoglobin A1c are not sensitive (but are highly specific) at detecting probable diabetes mellitus among Hispanics/Latinos, independent of heritage group. Assessing cardiovascular risk factors at diagnosis might prompt multitarget interventions and reduce health complications in this young population.

RESUMO

OBJECTIVE: To assess the prevalence of cervical cancer screening through Papanicolaou (Pap) test utilization and its association with sexual behaviors among a population-based sample of Hispanic women in Puerto Rico (PR). METHODS: This study was a secondary data analysis of the database of a cross-sectional study of HPV infection in PR (2010-2013; n = 554 women). Pap test utilization (past 3 years) was self-reported and sexual risky behavior was defined as an index that considered the following sexual behaviors: early age of sexual debut (≤16 years), 11 or more lifetime sexual partners, and 2 or more sexual partners in the last year. Multivariable logistic regression was used to estimate the magnitude of the association between sexual risk behavior and Pap test utilization, after adjusting for socioeconomic and lifestyles characteristics. RESULTS: The overall prevalence of Pap test utilization was 78.0%. Pap test screening varied with sexual behavior, with women with none or one risky sexual behavior having higher odds of Pap test utilization in the past 3 years (odds ratio [OR], 1.74; 95% CI, 1.03-2.93) compared with those with two or three risky sexual behaviors. This difference remained marginally significant (p < .10) after adjusting for age, educational attainment, smoking status and STI history (OR, 1.72; 95% CI, 0.96-3.08). CONCLUSIONS: The prevalence of cervical cancer screening in this population (78%) is still below Healthy People 2020 recommendations (93%). Also, women with risky sexual behaviors are less likely to have been screened. Efforts to promote cervical screening programs should focus on these high-risk women as a method for cervical cancer prevention and control.

RESUMO

The objective of this study was to compare sociodemographic, behavioral and clinical characteristics associated with HIV among Men who have sex with Men (MSM) and men who have sex with women (MSW) in Puerto Rico. Data from a population-based cross-sectional study in PR (2005-2008) was analyzed. Descriptive statistics were used to describe the study sample and bivariate analyses were performed to identify differences of sociodemographic, behavioral and clinical characteristics between MSM and MSW. Exact logistic regression models adjusting for age were constructed for each risk behavior associated to MSM in bivariate analysis. Of the 674 men interviewed, 6.1% (n=41) reported ever having sex with men. Age-adjusted logistic regression models indicated that MSM were significantly more likely than MSW to have first sexual intercourse before the age of 15 (POR=2.6; 95%CI= 1.3, 5.3) and have at least 10 lifetime sex partners (POR=2.8; 95%CI= 1.4,5.9). Also, MSM were significantly more likely to report lifetime use of marihuana (POR=2.7; 95%CI= 1.3,5.8), cocaine (POR=2.5; 95%CI= 1.2,5.0), amphetamines (POR=3.8; 95%CI= 1.4,9.2) and sedatives or tranquilizers (POR=3.3; 95%CI= 1.4,7.2). Also, MSM were 13 times more likely to be HIV seropositive as compared to MSW (POR=13.3; 95%CI=1.7,102.0). In this population-based sample of men living in Puerto Rico, self-reported same-sex behavior is strongly associated with HIV, and other behavioral factors associated with HIV. Future targeted research is still necessary for the development of intervention programs among MSM in Puerto Rico.

RESUMO

UNLABELLED: Lynch syndrome (LS) is an autosomal dominant disorder caused by DNA mismatch repair (MMR) system deficiencies. Women affected by LS present a 40% to 60% lifetime risk of endometrial cancer (EC). OBJECTIVE: This case-case study aims to determine the frequency of the hMLH1, hMSH2, and hMSH6 MMR proteins and the factors (age, family history of cancer [FHC] related to LS, and body mass index [BMI]) associated to their absence in EC patients attending the University District Hospital of San Juan, Puerto Rico. MATERIALS AND METHODS: Twenty cases were preliminary evaluated for the MMR protein expression by immunohistochemistry testing and classified as positive cases (presence of protein) or negative cases (absence of protein). The statistical analysis was based on the logistic regression model using the maximum likelihood estimation (MLE). The Bayesian approach was used to determine the posterior probability (posterior Pr[odds ratio {OR} > 1]). RESULTS: Results showed absence for at least 1 MMR protein in 25% of the cases, 15% for hMLH1, and 10% for hMSH2. None of the cases showed an absence for hMSH6. The MLE demonstrated that women diagnosed with EC before the age of 50 (OR: 12.4; 95% confidence interval [CI] = 0.5-322.7), having FHC related to LS (OR: 17.7; 95% CI = 0.6-534.6), and having lower BMI (OR: 2.38; 95% CI = 0.39-14.28) present higher odds than their counterparts of lacking an MMR protein, once adjusted for potential predictors (P > 0.05). The posterior probability that an excess risk of lacking an MMR protein occurs was 95% or greater for each predictor. CONCLUSIONS: Our study in this Hispanic population supports previous studies in that younger age, FHC, and lower BMI are associated with increased odds of having an absence of MMR protein expression. Further studies with larger sample sizes should be performed.

RESUMO

OBJECTIVES: To describe the prevalence of obesity and determine its association with blood pressure, serum lipids and lifestyles in adolescents attending a public junior-high school in San Juan, Puerto Rico. METHODS: During the 1999-2000 academic school year, 352 students, ranging in age from 12 years to 16 years, were screened for weight, height, and blood pressure. A sub-sample of voluntary adolescents (n = 26) was screened for serum lipids and lifestyles were assessed using a standardized questionnaire. RESULTS: The prevalence of level I obesity and level II obesity among 12 to 16 years old adolescents were 33.2% and 14.2%, respectively. The mean systolic and diastolic blood pressures were significantly higher in obese than in non-obese adolescents (p < .001). There were no significant differences in serum lipids between the study groups (p > .05). However, the obese group showed higher median levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. The study group reported engaging in hazardous lifestyles (alcohol intake, smoking, and unhealthy eating patterns), but no real differences in lifestyles were found between obese and non-obese groups (p > .05). CONCLUSIONS: A high prevalence of level I and level II obesity was found in this population. In addition, significant positive correlations between blood pressure and body mass index were observed. This study underscores the need to assess the burden of obesity in Puerto Rico in order to develop community intervention strategies encouraging early detection and conduct modification towards healthier lifestyles.
