RESUMEN

BACKGROUND AND AIMS: Adequate dietary intakes of essential micronutrients are critical to prevent insulin resistance (IR)-related diseases. Even though the excess calorie intake linked with obesity is also associated with such diseases, no previous studies evaluated the importance of meeting the Dietary Reference Intake (DRI) of micronutrients in relation to calorie intake in those at risk for developing IR. METHODS AND RESULTS: We evaluated the relationship between the ability or failure to meet the DRI of micronutrients in relation to daily calorie intake in 463 childbearing-age women with a higher prevalence of IR. 56-65% women met the DRIs for vitamin B12, vitamin C, thiamine, and riboflavin while only 0%-49% met the DRIs for folate, pyridoxine, niacin, pantothenic acid, total carotene, vitamins A, D and E by consuming an acceptable number of calories. Women who met the DRIs of folate and vitamin C within acceptable daily calorie intakes were 59% and 66% less likely to have higher Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) compared to women who did not. CONCLUSIONS: Understanding the mechanisms that explain our findings will be of value to address IR-associated with exposure to high calorie/low-micronutrient dense diets consumed by childbearing-age women. Since there is a global recognition that IR has been increasing in adults and children, similar studies of this nature in pregnant women at risk for IR will provide much needed data to assess the burden of such adverse dietary habits in the offspring. Our study approach may form the foundation for such studies.

RESUMEN

Human papillomavirus (HPV) is a common sexually transmitted disease worldwide. While burden of HPV-associated cancers and mortality is higher in low-income countries, there is limited data about knowledge of it among health care students and professionals. We assessed awareness and knowledge of HPV, its related diseases, and HPV vaccine among 333 participants, composed of 146 medical students (MSs) and professionals (MPs) and 187 nursing students (NSs) and professionals (NPs) using a 40-question survey between July 2018 and February 2019. Surveys were conducted in English language using both paper and an online version. Most participants reported that they had heard of HPV and cervical cancer. However, 91.76% of MPs and 77.97% of MSs, but only 41.11% of NPs and 36.17% NSs reported knowing that HPV types 16 and 18 caused cervical cancer. Likewise, about two-thirds of MPs and MSs reported having the knowledge that HPV 6 and 11 caused genital warts versus only a little over one-fourth of NPs and NSs. Only 55.91% of NPs and 51.61% of NSs were aware that HPV could cause cancer in both men and women, whereas 42.35% of MPs, 64.41% of MSs, 41.76% of NPs, and 40.66% of NSs were aware that the vaccine could be given to both boys and girls. While medical professionals were relatively more knowledgeable about HPV and related diseases, overall, knowledge about the HPV vaccine was low among all groups. This knowledge gap is concerning and warrants further attention to fight HPV-related public health burden in Nepal.

RESUMEN

OBJECTIVES: We examined breast milk of mothers and urine of infants before and after introduction of supplementary foods for aflatoxin M1 (AFM1) and the association between AFM1 with maternal and infant diet. METHODS: A prospective cohort study was conducted among mothers and infants ages 0-6 months and 7-12 months from June-October 2014. Sociodemographic, dietary, birth, and health data were collected. A breast milk sample was collected from each mother and a urine sample from each infant at baseline (time point 1) and monthly for 2 time points thereafter; samples collected at baseline and time point 3 were tested for AFM1. RESULTS: Almost 5% of breast milk and 15.7% of urine samples tested AFM1-positive. The median AFM1 in breast milk was 0.020 ng/mL and in urine 0.077 ng/mg creatinine. At time point 3, infants of 5 of the 6 mothers in each group who were AFM1-positive in breast milk were also AFM1-positive in urine. Mothers' consumption of cooked maize/maize dough ≥ 3 days per week (OR 2.96, 95% CI = 1.19-7.34) and mothers' consumption of tamales made from maize ≥ 3 days per week (OR 0.28, 95% CI = 0.10-0.73) were significantly associated with AFM1 in infant urine. CONCLUSION: This is the first study in Guatemala documenting aflatoxin exposure in both breast milk of lactating mothers and infants´ urine during the first year of life. This may have important implications in understanding the multicausality of the high rates of stunting among children < 5 years old in Guatemala.

RESUMEN

INTRODUCTION: Intrauterine devices are the most effective long-acting reversible contraceptives, but in many developing countries, such as Jamaica, these devices remain underutilized. METHODS: A cross-sectional informative intervention was conducted among women ≥ 18 years of age attending postnatal clinics in western Jamaica from May to August 2018. Data were collected using an investigator-administered questionnaire/pre-test followed by a 12-slide PowerPoint® presentation and a post-test. RESULTS: Most of the 299 women who participated were 18-29 years of age, with a mean age of 27.1 (SD ± 6.1) years. Most had their first pregnancy between ages 18 and 24 years, with mean age at first pregnancy of 20.2 (SD ± 4.0) years. Only 3.0% of participants reported current use of an intrauterine device; 3.5% reported using an intrauterine device in the past. For nearly every measure of knowledge of intrauterine devices, there was a significant change in the proportion of participants who got the correct answer from the pre-test to the post-test. The mean summed pre-test knowledge score was 9.54 (SD ± 3.46) and the post-test score was 15.23 (SD ± 1.92); the possible total score is 18. The difference between the mean scores (5.69 points) was also significant. CONCLUSION: The intervention resulted in significant change in knowledge of intrauterine devices among the women and cleared up many misconceptions that may have contributed to reluctance of women to use intrauterine devices. Women of reproductive age in Jamaica should be counseled on contraceptive methods including intrauterine devices so that these devices can be considered in their contraceptive choices.

RESUMEN

BACKGROUND: Menstruation, a natural biologic process is associated with restrictions and superstitious beliefs in Nepal. However, factual data on women's perspectives on menstrual practices and restrictions are scarce. This study aimed to assess socio-cultural perceptions of menstrual restrictions among urban Nepalese women in the Kathmandu valley. METHODS: Using a clustered random sampling, 1342 adolescent girls and women of menstruating age (≥15 years) from three urban districts in the Kathmandu valley completed a survey related to menstrual practices and restriction. This was a cross-sectional survey study using a customized program allowing pull-down, multiple choice and open-ended questions in the Nepali language. The self-administered questionnaire consisted of 13 demographic questions and 22 questions related to menstruation, menstrual hygiene, socio-cultural taboos, beliefs and practices. Univariate descriptive statistics were reported. Unadjusted associations of socio-cultural practices with ethnicity, education, four major social classes, three major religions, marital status and family type were assessed using logistic regression models. RESULTS: More than half (59%) of the participants were aged between 15- < 25 years. The majority were Hindus (84.5%), reported not praying during menstruation (83.1%) and were encouraged by their mothers (72.1%) to practice a range of menstrual restrictions. Purifying either the kitchen, bed, bedsheets or other household things on the fourth day of menstruation was reported by 66.1% of the participants, and 45.4% saw menstruation as a "bother" or "curse." There were differences among social classes, where participants of the Janajati caste, an indigenous group, were more likely to enter places of worship [OR (95%CI): 1.74 (1.06-2.86)] and pray [OR (95%CI): 1.79 (1.18-2.71)] while menstruating, compared to the Brahmins. Participants with a master's degree were more likely to pray while menstruating, compared to participants with less than a high school education [OR (95%CI): 2.83 (1.61-4.96)]. CONCLUSION: This study throws light on existing social discriminations, deep-rooted cultural and religious superstitions among women, and gender inequalities in the urban areas of Kathmandu valley in Nepal. Targeted education and awareness are needed to make changes and balance between cultural and social practices during menstruation.

RESUMEN

In this study authors aimed to investigate the barriers to participation of a sample of Jamaican women in mammography screening. The data were obtained from a previous survey that was conducted in Jamaica from June to August 2013 in the four parishes (Hanover, St. James, Trelawny, and Westmoreland) served by the Western Regional Health Authority (WRHA). WRHA served four hospitals, five non-randomized health centers, and five sites of community events. The sample consisted of women ranging in age between 35 and 83 years, with the mean age of 50.2 (SD = 10.6). The authors used a logistic regression to determine the extent to which variables were associated with breast cancer screening. The level of significace was 0.1 for the bivariate and multivariable analysis. The main factors associated with the lack of breast cancer screening among the women were: being less than 50 years old, single, never thought about breast cancer screening, in need of childcare, and having more than three children. We identified significant barriers to participation in mammography screening experienced by a sample of Jamaican women. Our results suggest that it is necessary to increase the awareness of the importance of breast screening importance among the women who may never have thought about mammography.

RESUMEN

BACKGROUND: This study was conducted to identify barriers and facilitators to cervical cancer screening, diagnosis, follow-up care, and treatment among human immunodeficiency virus (HIV)-infected women and clinicians and to explore the acceptability of patient navigators in Tanzania. MATERIALS AND METHODS: In 2012, we conducted four focus groups, two with HIV-positive women and two with clinicians who perform cervical cancer screening, diagnosis, follow-up care, and treatment. Transcriptions were analyzed using thematic analysis. RESULTS: Findings from the patient focus groups indicate the prevalence of fear and stigma surrounding cervical cancer as well as a lack of information and access to screening and treatment. The clinician focus groups identified numerous barriers to screening, diagnosis, follow-up care, and treatment. Participants in both types of groups agreed that a patient navigation program would be an effective way to help women navigate across the cancer continuum of care including screening, diagnosis, follow-up care, and treatment. CONCLUSION: Given the fear, stigma, misinformation, and lack of resources surrounding cervical cancer, it is not surprising that patient navigation would be welcomed by patients and providers. IMPLICATIONS FOR PRACTICE: This article identifies specific barriers to cervical cancer screening and treatment from the perspectives of both clinicians and patients in Tanzania and describes the acceptability of the concept of patient navigation.

RESUMEN

BACKGROUND: Cervical Cancer (CC) is the number one cancer among women in sub-Saharan Africa. Although CC is preventable, most women in developing countries do not have access to screening. METHODS: This cross-sectional study was conducted to determine the prevalence and risk factors for cervical lesions using visual inspection with acetic acid (VIA) among 112 HIV positive and 161 negative women aged 18-69 years. RESULTS: The presence of cervical lesions was greater among HIV positive (22.9%) than HIV negative women (5.7%; p < 0.0001). In logistic models, the risk of cervical lesions among HIV positive women was 5.24 times higher when adjusted by age (OR 5.24, CI 2.31-11.88), and 4.06 times higher in a full model (OR 4.06, CI 1.61-10.25), than among HIV negative women. In the age-adjusted model women who had ≥2 lifetime sexual partners were 3 times more likely (OR 3.00, CI 1.02-8.85) to have cervical lesions compared to women with one lifetime partner and the odds of cervical lesions among women with a history of STIs were 2.16 greater (OR 2.16, CI 1.04-4.50) than among women with no previous STI. In the fully adjusted model women who had a previous cervical exam were 2.5 times more likely (OR 2.53, CI 1.06-6.05) to have cervical lesions than women who had not. CONCLUSIONS: The high prevalence of HIV infection and the strong association between HIV and cervical lesions highlight the need for substantial scale-up of cervical screening to decrease the rate of CC in Swaziland.

RESUMEN

UNLABELLED: Tanzania has the highest burden of cervical cancer in East Africa. This study aims to identify perceived barriers and facilitators that influence scale-up of regional and population-level cervical cancer screening and treatment programs in Tanzania. Convenience sampling was used to select participants for this qualitative study among 35 key informants. Twenty-eight stakeholders from public-sector health facilities, academia, government, and nongovernmental organizations completed in-depth interviews, and a seven-member municipal health management team participated in a focus group discussion. The investigation identified themes related to the infrastructure of health services for cervical cancer prevention, service delivery, political will, and sociocultural influences on screening and treatment. Decentralizing service delivery, improving access to screening and treatment, increasing the number of trained health workers, and garnering political will were perceived as key facilitators for enhancing and initiating screening and treatment services. In conclusion, participants perceived that system-level structural factors should be addressed to expand regional and population-level service delivery of screening and treatment. IMPLICATIONS FOR PRACTICE: Tanzanian women have a high burden of cervical cancer. Understanding the perceived structural factors that may influence screening coverage for cervical cancer and availability of treatment may be beneficial for program scale-up. This study showed that multiple factors contribute to the challenge of cervical cancer screening and treatment in Tanzania. In addition, it highlighted systematic developments aimed at expanding services. This study is important because the themes that emerged from the results may help inform programs that plan to improve screening and treatment in Tanzania and potentially in other areas with high burdens of cervical cancer.

RESUMEN

Adherence to clinical appointment schedules by patients on antiretroviral therapy (ART) is necessary for the prevention of medication interruptions, viral rebound, and the development of drug resistance. An observational study conducted in 2010, Enablers and Adherence to Antiretroviral Therapy in Cambodia, sought to identify factors that predict on-time clinical appointment attendance by patients on ART. Clinical data, including appointment attendance across five consecutive visits, were collected from hospital records on a random sample of ART patients at government referral hospitals (RHs) in Battambang Province, Cambodia. Interviews were conducted to obtain quantitative information from patients on their experiences of support services provided by local NGOs and RHs. This information was used to identify ART patient care and support system factors that could potentially enable patients to adhere to clinical appointment schedules. These factors included adherence counseling, support groups, home-based care (HBC) services, and support provided for transportation to ART appointments. Bivariate and multivariable logistic regression analysis was done to assess relationships between system variables and the ART appointment adherence outcome. Of the 289 study participants, 20.4% had missed at least one of the five appointments in the study period. The hospital source of ART services, participation in a hospital-based support group, receiving a loan from a microfinance institution, and the frequency of adherence counseling were found to be associated with ART appointment adherence. No significant associations were found between other support system factors such as HBC, transportation support, food/monetary support, and appointment adherence.

RESUMEN

Despite declines in breast cancer mortality rates in developed countries, mortality rates remain high in Jamaica due to low levels of screening and lack of early detection. We hypothesized that a theory-based health educational intervention would increase awareness of breast cancer and intention to screen among women in Western Jamaica. Two hundred and forty six women attending hospitals or clinics were enrolled in an educational intervention consisting of a pretest, breast cancer presentation, and posttest if they had never been screened or had not been screened in 5 years or more. The questionnaires assessed attitudes and knowledge of risk factors and symptoms related to breast cancer. Participants were followed approximately 6 months after the intervention to determine whether they accessed breast cancer screening. There were statistically significant increases (p < 0.0001) in the percentage of correct knowledge responses and in participants' intention to screen from pretest to posttest. The greatest posttest improvements were among items measuring knowledge of breast cancer screening tests and risk factors. Of the 134 women who were reached by phone for post-intervention follow-up, 30 women (22.4 %) were screened for breast cancer and 104 women (77.6 %) had not been screened. The use of a theory-based educational intervention positively influenced knowledge of breast cancer risk factors, symptoms, and types of screening and increased screening rates in screening-naïve women. This theory-based educational intervention may be replicated to promote awareness of breast cancer and further increase screening rates in other areas of Jamaica and other developing countries.

RESUMEN

Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8-13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19-48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended <4 ANC visits. In an unadjusted model, these women had an increased likelihood of experiencing an adverse outcome (OR 2.27; 95% CI 1.30-3.94; p = 0.0038). High parity (>5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36% (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95% CI 1.16-5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.

RESUMEN

Aflatoxin B1 is a persistent public health issue in Ghana. Assessment of AFB1 intervention efficacy is currently dependent on long-term biomarkers. This study was designed to determine whether daily AFM1 biomarker levels could be utilized as an early detection method for intervention efficacy. Participants were treated with a refined calcium montmorillonite clay (UPSN) or a placebo (calcium carbonate) in a crossover study. Urine samples were assessed for AFM1 levels daily. UPSN treatment reduced AFM1 biomarkers by 55% compared to the placebo. This is the first study to show that daily urinary AFM1 levels can be used as a biomarker of internal aflatoxin B1 exposure in short-term intervention trials to determine efficacy.

RESUMEN

Current American Cancer Society guidelines estimated that screening starting at the age of 25 years with Pap and/or human papillomavirus (HPV) testing is sufficient to prevent cervical cancer. The effect of having HPV infections without Pap-based care until age 25 on the prevalence of higher grades of cervical intraepithelial neoplasia (≥CIN 2) and their determinants are largely unknown. The objectives of the study were to document the potential effects of age-based changes in screening guidelines on the identification of ≥CIN 2 and their determinants. The study included 1,584 women diagnosed with abnormal Pap and tested for HPVs and histologic diagnoses of cervical lesions. The association between demographic/lifestyle factors and HPV status and risk of being diagnosed with ≥CIN 2 among younger (21-<25 years) or older (≥25 year) women was tested using unconditional multiple logistic regression models. We observed that younger women who are not screened have a similar or higher risk of developing specific high-risk HPV genotype-associated ≥CIN 2 lesions compared with older women who are screened according to the current guidelines. In addition, younger women who reported live births, smoking, contraceptive use, and a higher number of sexual partners were significantly at higher risk of being diagnosed with ≥CIN 2. Targeted screening of younger women at risk for developing ≥CIN 2 will address the concern of overtreatment while providing the recommended care to those who require such care to prevent the development of cervical cancer. PREVENTION RELEVANCE: This study documents the concerns of the age-based changes in screening guidelines on the identification of higher grades of cervical intraepithelial neoplasia and their determinants in women diagnosed with abnormal Pap smear and emphasize the need for targeted screening of younger women to prevent cervical cancer.

RESUMEN

BACKGROUND: About 90% of new cervical cancer cases and deaths worldwide in 2020 occurred in low- and middle-income countries. This can be attributed to the low rates of cervical cancer screening in these countries. This study was conducted to identify factors associated with lack of cervical cancer screening among women in western Jamaica with the aim to increase screening and decrease cervical cancer risk. METHODS: This cross-sectional study assessed associations between previous Pap testing or lack of testing in five years or more, sociodemographic characteristics, attitudes, and knowledge of cervical cancer among women recruited from clinics and community events in the four parishes of western Jamaica. Analyses included chi-square tests, Fisher's exact tests, and logistic regression. RESULTS: Of the 223 women included in the study, 109 (48.9%) reported Pap testing five years or more previous to the study. In the multivariate analysis, women from St. James (Odds Ratio [OR]: 3.35, 95% Confidence Interval [CI]: 1.12-9.99), Trelawny (OR: 5.34, 95% CI: 1.23-23.25), and Westmoreland (OR: 3.70, 95% CI: 1.10-12.50) had increased odds of having had Pap test screening compared to women from Hanover. Women ≥ 50 years of age compared to women 18-29 years of age (OR: 6.17, 95% CI: 1.76-21.54), and employed compared to unemployed women (OR: 2.44, 95% CI: 1.15-5.20) had increased odds of Pap test screening. Similarly, women with one (OR: 4.15, 95% CI: 1.06-16.22) or two or more children (OR: 8.43, 95% CI: 2.24-31.63) compared to women with no children had higher odds of screening. Women who were aware, compared to women who were unaware, of the purpose of Pap tests had increased odds of screening (OR: 3.90, 95% CI: 1.55-9.82). Lastly, women who believed Pap tests were painful compared to women who did not, had decreased odds of having had a Pap test (OR: 0.33, 95% CI: 0.16-0.71). CONCLUSIONS: Uptake of Pap tests among the women was suboptimal and varied among parishes. Young women and women without children were less likely to have ever been screened. Increased education of the purpose of Pap tests to treat pre-cancer to prevent cancer and minimization of the notion that Pap tests are painful could promote screening among women in this population.

RESUMEN

Objectives: Prophylactic vaccines against high-risk human papillomaviruses (HR-HPVs) hold promise to prevent the development of higher grade cervical intraepithelial neoplasia (CIN 2+) and cervical cancer (CC) that develop due to HR-HPV genotypes that are included, in HPV vaccines, but women will continue to develop CIN 2+ and CC due to HR-HPV genotypes that are not included in the quadrivalent HPV vaccine (qHPV) and 9-valent HPV vaccine (9VHPV). Thus, the current vaccines are likely to decrease but not entirely prevent the development of CIN 2+ or CC. The purpose of the study was to determine the prevalence and determinants of CIN 2+ that develop due to HR-HPVs not included in vaccines. Methods: Study population consisted of 1476 women tested for 37 HPVs and known to be negative for qHPVs (6/11/16/18, group A, n = 811) or 9VHPVs (6/11/16/18/31/33/45/52/58, group B, n = 331), but positive for other HR-HPVs. Regression models were used to determine the association between plasma concentrations of micronutrients, socio-demographic, lifestyle factors and risk of CIN 2+ due to HR-HPVs that are not included in vaccines. Results: The prevalence of infections with HPV 31, 33, 35 and 58 that contributed to CIN 2+ differed by race. In group A, African American (AA) women and current smokers were more likely to have CIN 2 (OR = 1.76, P = 0.032 and 1.79, P = 0.016, respectively) while in both groups of A and B, those with higher vitamin B12 were less likely to have similar lesions (OR = 0.62, P = 0.036 and 0.45, P = 0.035, respectively). Conclusions: We identified vitamin B12 status and smoking as independent modifiable factors and ethnicity as a factor that needs attention to reduce the risk of developing CIN 2+ in the post vaccination era. Continuation of tailored screening programs combined with non-vaccine-based approaches are needed to manage the residual risk of developing HPV-related CIN 2+ and CC in vaccinated women.

RESUMEN

Current American Cancer Society (ACS) guidelines estimated that screening starting at the age of 25 years with Pap and/or human papillomavirus (HPV) testing is sufficient to prevent cervical cancer (CC). The effect of having HPV infections without Pap-based care until age 25 on the prevalence of higher grades of cervical intraepithelial neoplasia (≥ CIN 2) and their determinants are largely unknown. The objectives of the study were to document the potential effects of age-based changes in screening guidelines on the identification of ≥ CIN 2 and their determinants. The study included 1584 women diagnosed with abnormal Pap and tested for HPVs and histological diagnoses of cervical lesions. The association between demographic/lifestyle factors and HPV status and risk of being diagnosed with ≥ CIN 2 among younger (21-<25 years) or older (≥ 25 year) women was tested using unconditional multiple logistic regression models. We observed that younger women who are not screened have a similar or higher risk of developing specific high risk (HR)-HPV genotype-associated ≥ CIN 2 lesions compared to older women who are screened according to the current guidelines. In addition, younger women who reported live births, smoking, contraceptive use and a higher number of sexual partners were significantly at higher risk of being diagnosed with ≥ CIN 2. Targeted screening of younger women at risk for developing ≥ CIN 2 will address the concern of overtreatment while providing the recommended care to those who require such care to prevent the development of CC.

RESUMEN

BACKGROUND: Aflatoxin suppresses cellular immunity and accentuates HIV-associated changes in T- cell phenotypes and B- cells. OBJECTIVE: This prospective study was conducted to examine the association of aflatoxin levels with CD4 T-cell count and antiretroviral therapy uptake over time. METHODS: Sociodemographic and food data were collected from antiretroviral therapy naïve HIV-infected patients. CD4+ counts were collected from participants' medical records. Plasma samples were tested for aflatoxin B1 albumin adducts, hepatitis B surface antigen, and HIV viral load. Participants were separated into high and low aflatoxin groups based on the median aflatoxin B1 albumin adduct level of 10.4 pg/ml for data analysis. RESULTS: Participants with high aflatoxin B1 albumin adduct levels had lower mean CD4 at baseline and at each follow-up period. Adjusted multivariable logistic regression analysis showed that higher baseline aflatoxin B1 adduct levels were associated with statistically significant lower CD4 counts (est = -66.5, p = 0.043). Not starting ART and low/middle socioeconomic status were associated with higher CD4 counts (est = 152.2, p<0.001) and (est = 86.3, p = 0.027), respectively. CONCLUSION: Consistent correlations of higher aflatoxin B1 adduct levels with lower CD4 over time indicate that there is an independent early and prolonged effect of aflatoxin on CD4 even with the initiation of antiretroviral therapy. The prospective study design, evaluation of baseline and follow-up measures, extensive control for potential confounders, and utilization of objective measures of aflatoxin exposure and CD4 count provide compelling evidence for a strong epidemiologic association that deserves careful attention in HIV care and treatment programs.

RESUMEN

OBJECTIVE: Since a quantitative polymerase chain reaction (qPCR) assay targeting the E1 region of HPV genome is cost-effective/simple to perform, we evaluated the agreement between the Roche Diagnostics Linear Array (RDLA) genotyping test and qPCR-based E1 assay to detect HR-HPV genotypes that are included or not included in HPV vaccines and compared their accuracy to detect CIN 2+. METHODS: Study population included 257 African American (AA) and 266 Caucasian American (CA) diagnosed with intraepithelial neoplasia (CIN) grades ≤CIN 1 or ≥CIN 2 (CIN 2+) and tested for HPV by the RDLA and E1 assay. The concordance was determined using Gwet's AC1. The calculated positive predictive value (PPV) and negative predictive value (NPV) of the two assays were used to determine their suitability to detect CIN lesions. RESULTS: Overall, the E1 assay showed substantial agreement with the RDLA assay to detect any HR-HPV genotype and the agreement was higher in women diagnosed with CIN 2+ than ≤CIN 1. The concordance was largely higher in Cas than in Aas. The NPV and PPV values to detect CIN lesions were similar between the two assays. CONCLUSION: Utilization of the HPV E1 assay as a tool for CC screening could be a cost-effective approach that applies to both vaccinated and unvaccinated populations.

RESUMEN

OBJECTIVE: Our aim was to quantify prevalence, incidence, and recurrence of oral lesions (OL) among a population in the Southeast. METHODS: A retrospective study based on chart review was conducted among patients (n = 744) who were ≥19 years of age and initiated highly active antiretroviral therapy (HAART) between January 2000 and June 2006 at the University of Alabama at Birmingham (UAB) 1917 Clinic. Patients' laboratory data and oral conditions were recorded for 2 years after enrollment into the study. RESULTS: During 2 years of follow-up, the period prevalence of individuals experienced at least one OL was 35.6% (266/744). Among all of the 374 episodes of OL, 183 were new cases, while 57 were recurrences. The OL person-visit incidence rate was 0.02 per 100 person-visits. Oropharyngeal candidiasis (OPC) was the most frequent manifestation in terms of period prevalence (74.9%) with a person-visit incident rate of 0.01 per 100 person-visits. CONCLUSIONS: Patients undergoing HAART continue to be affected by HIV-related oral conditions, especially OPC. These results clearly indicate that OL during HIV infection are still highly prevalent in spite of the improvements in medical care and the availability of HAART.
