RESUMEN

BACKGROUND: COVID-19 stay-at-home orders enacted in New Orleans, LA on March 16, 2020, may have caused changes in the way young men interacted with sex partners. METHODS: An online substudy was conducted (May 21, 2020 to June 9, 2020) among Black men who have sex with women, 18 years and older, and who had previously enrolled in the parent study Check It (May 17, 2017 to March 6, 2020) to assess changes in sexual behavior during the stay-at-home orders. RESULTS: Among 111 participants, from enrollment in Check It to during stay-at-home orders, recent vaginal sex declined from 96.4% to 47.8% (P < 0.0001), reports of multiple female sex partners declined from 45.0% to 14.4% (P < 0.0001), and sexual abstinence increased from 3.6% to 38.7% (P < 0.0001). Among those who did have vaginal sex, condomless sex rates did not change between enrollment in Check It and the substudy (64.5% vs 67.9%, P = 0.68). During stay-at-home orders oral sex, virtual sex, and pornography viewing were 40.5%, 42.3%, and 76.6%, respectively. Some (17.1%) acquired a new sex partner during stay-at-home orders, and 44.1% left their home to meet a partner for sex. Only 27.9% had seen information about safe sex during the pandemic. Income was diminished for 62.2% and 23.4% moved away from New Orleans when stay-at-home orders were enacted. CONCLUSIONS: Although there was an overall reduction in physical sex, half of participants reported physical sex, with many leaving their home to have sex during stay-at-home orders and many not using condoms. Others adopted sexual abstinence, increased virtual sex, and/or pornography viewing, which may have protected them from both sexually transmitted infections and COVID-19.

RESUMEN

Women living with HIV (WLWH) suffer from poor viral suppression and retention postpartum. The effect of perinatal depression on care continuum outcomes during pregnancy and postpartum is unknown. We performed a retrospective cohort analysis using HIV surveillance data of pregnant WLWH enrolled in perinatal case management in Philadelphia and evaluated the association between possible or definite depression with four outcomes: viral suppression at delivery, care engagement within three months postpartum, retention and viral suppression at one-year postpartum. Out of 337 deliveries (2005-2013) from 281 WLWH, 53.1% (n = 179) had no depression; 46.9% had either definite (n = 126) or possible (n = 32) depression during pregnancy. There were no differences by depression status across all four HIV care continuum outcomes in unadjusted and adjusted analyses. The prevalence of possible or definite depression was high among pregnant WLWH. HIV care continuum outcomes did not differ by depression status, likely because of supportive services and intensive case management provided to women with possible or definite depression.

RESUMEN

Consumption of rice-based foods provides essential nutrients required for infants and toddlers' growth. However, they could contain toxic and excess essential elements that may affect human health. The study aims to determine the composition of rice-based baby foods in the USA and outside and conduct a multiple-life stages probabilistic exposure and risk assessment of toxic and essential elements in children. Elemental concentrations were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in thirty-three rice-based baby foods. This includes 2 infant formulas, 11 rice baby cereals, and 20 rice snacks produced primarily in the United States, China, and other countries. A probabilistic risk assessment was conducted to assess risks of adverse health effects. Results showed that infant formula had higher median concentrations of selenium (Se), copper (Cu), zinc (Zn), sodium (Na), magnesium (Mg), calcium (Ca), and potassium (K) compared to rice baby cereal and rice snacks. On the contrary, rice snacks had the highest median concentration of Arsenic (As) (127 µg/kg) while rice baby cereals showed the highest median concentration of Cd (7 µg/kg). A higher lifetime estimated daily intake was observed for samples manufactured in the USA compared to those from China and other countries. Hazard quotient (HQ < 1) values were suggestive of minimal adverse health effects. However, lifetime carcinogenic risk analysis based on total As indicated an unacceptable cancer risk (>1E-04). These findings show a need for ongoing monitoring of rice-based foods consumed by infants and toddlers as supplementary and substitutes for breast milk or weaning food options. This can be useful in risk reduction and mitigation of early life exposure to improve health outcomes.

RESUMEN

We determined the concentrations of toxic and essential elements in rice and other grains (lentils, barleys, beans, oats, wheat, and peas) grown in the United States (US) and other countries using Inductively Coupled Plasma Mass Spectrometry (ICPMS). Results showed that median concentrations (in µg/kg) for toxic elements in white rice from the US were 131, 2.8, and 6.5 for arsenic (As), lead (Pb), and cadmium (Cd), respectively. White rice from Thailand, India, and Italy showed higher median toxic elements concentrations (in µg/kg) of 155 for As, 3.6 for Pb, and 8.4 for Cd, than for white rice from the US. Brown rice from the US showed median concentrations (in µg/kg) of 217 (As), 4.5 (Pb), and 17.4 (Cd) while other grains showed median concentrations (in µg/kg) of 5.4, 4.6, and 6.7 for these elements, respectively. None of the samples exceeded the codex standards set for Pb (200 µg/kg in cereals and pulses) and Cd (100 µg/kg in cereals/pulses and 400 µg/kg in polished rice). However, brown rice and one white rice sample did exceed the codex standard for As (200 µg/kg). Essential elements were higher in other grains than in white and brown rice. These findings suggest that alternating or coupling rice with other grains in one's diet could reduce exposure to toxic metals while providing more essential elements to rice diet.
