RESUMO

We evaluated mental health and substance use during the COVID-19 pandemic in 196 participants from the Miami Adult Studies on HIV (MASH) Cohort. A survey was administered between July-August of 2020, including validated measures of resilience and anxiety, a scale to measure COVID-19-related worry, and self-reported substance use. Compared to HIV-uninfected participants (n = 80), those living with HIV (n = 116) reported fewer anxiety symptoms, less COVID-19-related worry, and higher resilience. Those with more anxiety symptoms and lower resilience engaged in more frequent alcohol consumption, binge drinking, and cocaine use. Alcohol misuse was more common among HIV-uninfected participants. Cocaine use was reported by 21% fewer participants during the pandemic compared with 7.3 ± 1.5 months earlier. Possibly due to their experiences with HIV, PLWH responded with higher resilience and reduced worry and anxiety to the adversities brought by the COVID-19 pandemic.

RESUMO

Vitamin D3 or calcitriol (VitD3) has been shown to have anticancer and anti-inflammatory activity in in vitro models and clinical studies. However, its effect on HPV-16-related cancer has been sparsely explored. In this study, we aimed to determine whether monotherapy or combination therapy with cisplatin (CP) reduces tumor growth and affects survival and systemic inflammation. Treatments were administered to C57BL/6 mice with HPV-16-related tumors (TC-1 cells) as follows: (1) placebo (100 µL vehicle, olive oil, orally administered daily); (2) VitD3 (3.75 µg/kg calcitriol orally administered daily); (3) CP (5 mg/kg intraperitoneally, every 7 days); and (4) VitD3+CP. Tumor growth was monitored for 25 days, survival for 60 days, and the neutrophil-to-lymphocyte ratio (NLR) was evaluated on days 1 (baseline), 7, and 14. VitD3+CP showed greater success in reducing tumor volume compared to CP monotherapy (p = 0.041), while no differences were observed between CP and VitD3 monotherapy (p = 0.671). Furthermore, VitD3+CP prolonged survival compared to CP (p = 0.036) and VitD3 (p = 0.007). Additionally, at day 14 the VitD3 and VitD3+CP groups showed significantly lower NLR values than the CP group (p < 0.05, for both comparisons). Vitamin D3 could be a promising adjuvant in the treatment of cervical cancer or solid tumors and deserves further investigation.

RESUMO

The Coronavirus Disease 2019 (COVID-19) pandemic has disproportionately impacted people who use drugs (PWUD). This study explored relationships between drug use, COVID-19 testing, vaccination, and infection. This cross-sectional study was conducted in Miami, Florida between March 2021 and October 2022 as part of the National Institutes of Health (NIH) Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) initiative and the Miami Adult Studies on HIV (MASH) cohort. Users of cannabis, cocaine/crack, heroin/fentanyl, methamphetamines, hallucinogens, and/or prescription drug misuse in the previous 12 months were considered PWUD. Sociodemographic data, COVID-19 testing history, and vaccination-related beliefs were self-reported. Vaccinations were confirmed with medical records and positivity was determined with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing. Statistical analyses included chi-square tests and logistic regression. Of 1,780 participants, median age was 57 years, 50.7% were male, 50.2% Non-Hispanic Black, and 66.0% reported an annual income less than $15,000. Nearly 28.0% used drugs. PWUD were less likely than non-users to self-report ever testing positive for SARS-CoV-2 (14.7% vs. 21.0%, p = 0.006). However, 2.6% of participants tested positive for SARS-CoV-2, with no significant differences between PWUD and non-users (3.7% vs. 2.2%, p = 0.076). PWUD were more likely than non-users to experience difficulties accessing testing (10.2% vs. 7.1%, p = 0.033), vaccine hesitancy (58.9% vs. 43.4%, p = 0.002) and had lower odds of receiving any dose of a COVID-19 vaccine compared to non-users (aOR, 0.63; 95% CI, 0.49-0.81; p<0.001). PWUD presented with greater difficulties accessing COVID-19 testing, greater vaccine hesitancy, and lower odds of vaccination. Testing and immunization plans that are tailored to the needs of PWUD and consider access, trust-building campaigns, and education may be needed.

RESUMO

COVID-19 vaccines primarily prevent severe illnesses or hospitalization, but there is limited data on their impact during hospitalization for seriously ill patients. In a Mexican cohort with high COVID-19 mortality, a study assessed vaccination's effects. From 2021 to 2022, 462 patients with 4455 hospital days were analyzed. The generalized multivariate linear mixed model (GENLINMIXED) with binary logistic regression link, survival analysis and ROC curves were used to identify risk factors for death. The results showed that the vaccinated individuals were almost half as likely to die (adRR = 0.54, 95% CI = 0.30-0.97, p = 0.041). When stratifying by vaccine, the Pfizer group (BNT162b2) had a 2.4-times lower risk of death (adRR = 0.41, 95% CI = 0.2-0.8, p = 0.008), while the AstraZeneca group (ChAdOx1-S) group did not significantly differ from the non-vaccinated (adRR = 1.04, 95% CI = 0.5-2.3, p = 0.915). The Pfizer group exhibited a higher survival, the unvaccinated showed increasing mortality, and the AstraZeneca group remained intermediate (p = 0.003, multigroup log-rank test). Additionally, BNT162b2-vaccinated individuals had lower values for markers, such as ferritin and D-dimer. Biochemical and hematological indicators suggested a protective effect of both types of vaccines, possibly linked to higher lymphocyte counts and lower platelet-to-lymphocyte ratio (PLR). It is imperative to highlight that these results reinforce the efficacy of COVID-19 vaccines. However, further studies are warranted for a comprehensive understanding of these findings.

RESUMO

Ensuring equitable chronic kidney disease (CKD) education for Latine patients with low health literacy and low English proficiency stands as a critical challenge, and the "Caridad Awareness and Education" (CARE) initiative represents our ongoing effort to address this imperative issue. In collaboration with twenty-three patients living with CKD, diabetes and/or hypertension and twelve trained Community Health Workers (CHWs) from diverse Latine subgroups, we conducted a research initiative funded by the National Kidney Foundation. Our primary objective was to co-design and test culturally tailored patient education materials (PEMs) for underserved Latine adults at risk for or diagnosed with CKD. We effectively integrated Community-Engaged Research (CEnR) principles with a Human-Centered Design (HCD) approach to create a range of CKD-PEM prototypes in Spanish. Patient preferences for printed educational materials were clear. They favored printed materials that incorporated visual content with concise text over digital, email, texts, or online resources and personalized phone outreach and the involvement of CHWs. Additionally, patients identified their unwavering commitment to their families as a forceful motivator for caring for their kidney health. Currently, a culturally and linguistically tailored CKD flipchart for one-on-one education, led by CHWs, is undergoing a pilot testing phase involving a sample of one hundred Latine patients at risk for or diagnosed with CKD. This innovative approach signifies a commitment to amplifying the insights and expertise of the Latine community afflicted by kidney health disparities, effectively embracing a CEnR to forge meaningful and impactful CKD-PEMs.

RESUMO

There are contradictory results regarding changes in estimated glomerular filtration rate (eGFR) in coronavirus disease 2019 (COVID-19) survivors. An analysis of eGFR changes and clinical characteristics associated with those changes was conducted among COVID-19 survivors. eGFR values were compared at different time points (before and 4-, 8- and 12-months after COVID-19 infection). A multivariate generalized linear mixed model (GENLINMIXED procedure) with a binary logistic regression link was used to determine factors associated with eGFR reduction of ≥10 ml/min/1.73 m2. Being hospitalized (RR=2.90, 95% CI=1.10-7.68, P=0.032), treated with Ivermectin (RR=14.02, 95% CI=4.11-47.80, P<0.001) or anticoagulants (RR=6.51, 95% CI=2.69-15.73, P<0.001) are risk factors for a reduced eGFR. Having a low eGFR (<90 ml/min/1.73 m2) before COVID-19 infection, having B-positive blood type, diabetes, taking vitamin C during the acute phase of COVID-19 or suffering from chronic COVID-19 symptoms, were identified as protective factors. Analysis involving a two-way interaction (A x B, where A and B are factors) demonstrated that the combination of patients with a normal eGFR value before COVID-19 infection without diabetes (RR=58.60, 95% CI=11.62-295.38, P<0.001), or a normal eGFR value with being hospitalized for COVID-19 (RR=38.07, 95% CI=8.68-167.00, P<0.001), increased the probability of a reduced eGFR. The changes in eGFR in COVID-19 survivors varied depending on patient characteristics. Furthermore, the principal risk factors for post-COVID-19 eGFR reduction were analyzed in separate models.

RESUMO

This study explored barriers, motivators, and trusted sources of information regarding COVID-19 vaccination among Hispanic/Latine individuals. Hispanic/Latine is a broad social construct that encompasses people from heterogeneous countries and cultures. In the U.S., foreign-born Hispanics/Latines tend to have better health outcomes than U.S.-born individuals. Thus, the study examined whether nativity is a significant factor in COVID-19 vaccine hesitancy. Binary logistic regression and linear regression analyses were employed and revealed that, regardless of nativity, Hispanic/Latine participants face similar barriers and find similar sources of information trustworthy. Controlling for age and race, vaccination rates or perceived likelihood of getting vaccinated did not differ between the two groups. The two groups significantly differed in specific motivators for vaccination: foreign-born Hispanic/Latine individuals were more motivated to get the vaccine to keep themselves, their families, and their community safe, and more often believed vaccination is needed for life to return to normal. Study results provide important insights into similarities and differences in barriers, motivators, and trusted sources of information regarding COVID-19 vaccination among native and foreign-born Hispanic/Latine individuals.

RESUMO

Background: Smoking has been associated with mental disorders (MD). People who smoke are at a higher risk of contracting COVID-19 and experiencing more severe symptoms of the illness. This study aimed to investigate the relationship between cigarette smoking and MD before and during the COVID-19 pandemic and whether it was influenced by COVID-19-related stress in the MASH cohort. Methods: An ambispective design was used with data collected during the pandemic (July/August 2020) by the COVID-19-Related Worry Scale, a parameter for stress, and data collected at the participants' last cohort visit before the pandemic (December 2019). Results: In our sample of 314 participants, 58.6% were living with HIV, 39.2% had MD, 52.5% smoked before, and 47.8% smoked during the pandemic. Participants with MD were twice as likely to smoke cigarettes both before (aOR = 2.02, 95% CI: 1.21−3.37, p = 0.007) and during the pandemic (aOR = 2.10, 95% CI: 1.24−3.56, p = 0.006); and experienced higher levels of stress measured by the COVID-19-Related Worry Scale (8.59 [5.0−10.0] vs. 7.65 [5.0−10.0]; p = 0.026) compared to those without MD. Participants with MD and high levels of stress smoked more days per month (20.1 [0−30] days) than those with lower levels of stress (9.2 [0−30] days, p = 0.021), and more than those with high levels of stress, but no MD (2.6 [0−30] days, p < 0.001). Conclusions: Cigarette smoking decreased in the MASH cohort during the pandemic, but increased in participants with MD and higher levels of stress.

RESUMO

OBJECTIVE: The COVID-19 pandemic has dramatically impacted mental health, increasing rates of substance misuse. Resilience is a positive adaptation to stress that may act as a buffer against adverse mental health outcomes. Based on prior knowledge, we hypothesized that PLWH would display higher resilience than HIV-uninfected peers, and that high resilience would be associated with lower risk of substance misuse. METHODS: This analysis of the Collaborating Consortium of Cohorts Producing NIDA Opportunities (C3PNO) included data from six USA cohorts that administered a COVID-19-related survey with a 3-month follow-up during May 2020 and March 2021. All data was self-reported. The Brief Resilience Scale and General Anxiety Disorder-7 were utilized. Primary analyses consisted of multivariate generalized linear mixed models with random intercepts using binary logistic regression. RESULTS: A total of 1430 participants completed both surveys, of whom 670 (46.9%) were PLWH. PLWH had lower odds of anxiety (OR=0.67, 95% CI: 0.51-0.89) and higher odds of high resilience (OR=1.21, 95% CI: 1.02-1.44) than HIV-uninfected participants, adjusted for covariates. The presence of anxiety was associated with higher risk of misuse of all substances. High resilience was associated with lower risk of anxiety and misuse of substances, adjusted for covariates. CONCLUSIONS: Psychological resilience was associated with lower risk of anxiety and substance misuse, potentially serving as a buffer against poor mental and behavioral health during the COVID-19 pandemic. Further research is needed to identify pathways of resilience in the context of substance misuse and comprehensive resilience-focused interventions.

RESUMO

Thyroid hormone abnormalities are among the most common endocrine disorders comorbidly suffered alongside metabolic syndrome and type 2 diabetes mellitus (T2DM), and within the euthyroid range they may also impact other outcomes, such as mood disorders. This study aimed to observationally examine the relationship between TSH and social determinants of health and clinical measures in a euthyroid Hispanic/Latinx patient sample with a diagnosis of anxiety and/or depression disorders from a community health clinic. A needs assessment was completed using a random sample of 100 de-identified medical records of individuals who received free medical care, including mental health, at a community-based clinic. Those with low normal TSH (<2 mIU/L) compared with high normal TSH (≥2 mIU/L) had a greater odds of food insecurity (p = 0.016) and being at 100% of the federal poverty level (p = 0.015). The low normal TSH group had significantly higher fasting glucose (p = 0.046), hemoglobin A1c (p = 0.018), and total cholesterol (p = 0.034) compared with the high normal TSH group. In those with T2DM, individuals with low normal TSH had six-times greater odds of having high fasting glucose (p = 0.022) and high hemoglobin A1c (p = 0.029). These relationships warrant further study, to inform future public health policies and follow-up care for underserved and vulnerable communities.

RESUMO

BACKGROUND: Socioeconomic disadvantages and potential immunocompromise raise particular concerns for people living with HIV (PLWH) and other marginalized communities during the COVID-19 pandemic. In this study, we explored COVID-19 testing and the impact of the pandemic among participants from the Miami Adult Studies on HIV cohort, predominantly composed of low-income minorities living with and without HIV. METHODS: Between July and August 2020, a telephone survey was administered to 299 Miami Adult Studies on HIV participants to assess COVID-19 testing, prevention behaviors, and psychosocial stressors. Health care utilization, antiretroviral adherence, food insecurity, and substance use during the pandemic were compared with those of their last cohort visit (7.8 ± 2.9 months earlier). RESULTS: Half of surveyed participants had been tested for COVID-19, 8 had tested positive and 2 had been hospitalized. PLWH (n = 183) were 42% times less likely than HIV-uninfected participants to have been tested. However, after adjustment for age, employment, COVID-19 symptoms, mental health care, and substance use, the effect of HIV status was no longer significant. PLWH were more likely to have seen a health care provider, use face coverings, and avoid public transportation and less likely to be food insecure and drink hazardously. There were significant changes in substance use patterns during the pandemic when compared with those before. CONCLUSION: PLWH, compared with their HIV-uninfected peers, were more likely to engage in preventive measures and health care during the pandemic, potentially reducing their exposure to COVID-19. There were no reported changes in antiretroviral adherence or health care utilization, but there were changes in substance use; these need to be monitored as this crisis progresses.

RESUMO

OBJECTIVE: Adverse outcomes in hemodialysis patients have been attributed, in part, to the pro-inflammatory state prevalent in this population. This study examines the relationship between blood neutrophil-to-lymphocyte ratio (NLR) with nutrition markers and health outcomes in hemodialysis (HD) patients. DESIGN: This is a 12-month prospective cohort study that recruited 77 participants from May to Jun 2017. SETTINGS AND SUBJECTS: Patients receiving maintenance hemodialysis. MAIN OUTCOMES: Hospitalization, transplants and mortality. RESULTS: Of the 77 participants, 63.8% were hospitalized, 10 (13%) died of cardiovascular diseases and 6 (7.8%) had a kidney transplant. Spearman correlations using baseline values showed an inverse significant correlation between the total number of hospitalizations and BMI kg/m2 (BMI rho = - 0.37, P <0.001); a significant inverse correlation between NLR and albumin (rho = - 0.22, P = 0.028); and a significant direct correlation between baseline NLR and BMI kg/m2 (rho = 0.22, P = 0.028). Participants were grouped by their NLR value into quartiles for outcomes analysis: quartile 1 (NLR ≤ 1.75), quartile 2 (NLR 1.76-2.6), quartile 3 (NLR 2.7-3.9) and quartile 4 (NLR ≥ 4). The percentage of patients with the lowest level of inflammation (NLR ≤ 1.75) was greater for not hospitalized patients than for hospitalized (39.3% vs 16.3%, P = 0.025) and not hospitalized participants had higher BMI kg/m2 (mean ± SD) at baseline compared to those hospitalized (29.11 ± 5.4 vs 26.22 ± 5.34, P = 0.026). In a multivariate cox regression analysis, participants in the lowest quartile (NLR ≤ 1.75) were compared to the rest on hospitalization, mortality and transplant. Years in dialysis, BMI kg/m2 and NLR ≤ 1.75 were significant predictors of hospitalization after adjustment (P = 0.021, P = 0.005, P = 0.039; respectively) and we observed an association of low NLR with a hazard ratio (HR 0.44, 95% CI 0.20-0.96, P = 0.039), BMI (HR 0.90, 95% CI 0.85-0.97, P = 0.005) and years in dialysis (HR 0.90, 95% CI 0.83-0.98, P = 0.021) for hospitalization in overall participants. In a further analysis comparing the effect of low NLR in the subgroup of diabetic vs non-diabetics, it was observed that BMI kg/m2 was a significant predictor for hospitalization in the non-diabetic subgroup (P = 0.040) but not significant in the case of diabetics (P = 0.128) after adjustments. Years in dialysis and NLR ≤ 1.75 were significant predictors of hospitalizations in the subgroup of diabetic before and after adjustment (P = 0.049, P = 0.044; respectively). Having a low NLR decreased 73% the risk for hospitalization (HR 0.27 95% CI 0.07-0.96, P = 0.044) in this subgroup. Survival and hospitalization curves were analyzed by comparing all participants and the diabetic subgroup, in the lowest inflammation quartile vs the rest (NLR ≤ 1.75 vs NLR > 1.75). Participants with NLR ≤ 1.75 had 100% survival rate (log-rank test, P = 0.059) and lower hospitalization rate (log-rank test, P = 0.025); participants with diabetes had lower hospitalization rate (log-rank test, P = 0.039). CONCLUSION: NLR at baseline was associated with nutritional markers (albumin, BMI). Low NLR at baseline was a predictor of lower risk for hospitalizations in HD patients with diabetes.
