Differences of skin carotenoids and adherence to the Mediterranean Diet pattern in adults from Southern Italy and Dominican Republic.

BACKGROUND: The measurement of the skin carotenoids using the Veggie Meter® has emerged as a rapid objective method for assessing fruit and vegetable intake, highly recommended by the Mediterranean Diet (MD), which represents one of the healthiest dietary patterns, worldwide. This study aimed to examine differences in skin carotenoid content and degree of adherence to the MD pattern between two adult populations from Southern Italy and the Dominican Republic. METHODS: This cross-sectional study enrolled a total of 995 adults, 601 subjects from Italy and 394 from the Dominican Republic. All participants underwent anthropometric measurements and skin carotenoid assessment by Veggie Meter®. Adherence to the MD and lifestyle were evaluated using the Mediterranean Diet Adherence Screener (MEDAS) and the Mediterranean Lifestyle Index (MEDLIFE) questionnaires. Correlations between the skin carotenoid and MEDAS score were estimated using Pearson's correlation coefficient. Multiple linear regression models were created to determine variables that affect skin carotenoid score for both populations. RESULTS: Mean total skin carotenoids were higher in the Italian compared to the Dominican Republic population (342.4 ± 92.4 vs 282.9 ± 90.3; p < 0.005) regardless of sex (women: 318.5 ± 88.9 vs 277.3 ± 91.9, p < 0.005 and men: 371.7 ± 88.3 vs 289.5 ± 88.1, p < 0.005), and remaining statistically significant after age-adjustment of the Dominican Republic sample. Using the MEDAS questionnaire, we found a higher MD adherence score in the Italian than in the Dominican Republic population also after age-adjusting data (7.8 ± 2.1 vs 6.2 ± 3.7; p < 0.005) and even when categorized by sex (Italian vs age-adjusted Dominican Republic women: 7.9 ± 2.1 vs 6.3 ± 2.6; Italian vs age-adjusted Dominican Republic men: 7.7 ± 2.2 vs 6.0 ± 4.7; p < 0.005). Using the MEDLIFE test, total Italians presented a lower score with respect to the age-adjusted Dominican Republic population (3.2 ± 1.2 vs 3.4 ± 1.4; p < 0.05). In multiple regression analysis, skin carotenoids were associated with sex and negatively associated with BMI in the Italian population (sex: ß: 54.95; 95% CI: 40.11, 69.78; p < 0.0001; BMI: ß: - 1.60; 95% CI: - 2.98,0.86; p = 0.03), while they resulted associated with age and sex in the Dominican Republic population (age: ß: 2.76; 95% CI: 1.92, 3.56; p < 0.001; sex: ß: 23.29; 95% CI: 5.93, 40.64; p = 0.009). Interestingly, skin carotenoids were positively correlated with MEDAS score in both populations (Italy: r = 0.03, p < 0.0001, Dominican Republic: r = 0.16, p = 0.002). CONCLUSIONS: This study provides the assessment of the adherence to the MD and skin carotenoid content in adults living in Southern Italy and the Dominican Republic, showing a higher MD adherence score and a skin carotenoid content in inhabitants from the Mediterranean region. Our findings highlight the need to globally encourage fruit and vegetable intake, particularly in non-Mediterranean area.

The relationship between female orgasmic disorder, attention-deficit/hyperactivity disorder, and depression in Dominican women.

BACKGROUND: Female orgasmic disorder is listed in the DSM-5 and is defined as the persistent or recurrent inability to have an orgasm. Many depressed women may experience sexual dysfunction, including female orgasmic disorder. AIM: The study sought to analyze the relationship between depressive disorders and attention-deficit/hyperactivity disorder (ADHD) and their influence on the development of female orgasmic disorder. METHODS: A total of 221 Dominican women participated in this case-control study. The case group consisted of 107 women diagnosed with female orgasmic disorder, while the control group consisted of 114 women without any sexual dysfunction. OUTCOMES: The diagnosis of ADHD was obtained from the participants' medical records, previously conducted using the DSM-5-TR criteria. The Beck Depression Inventory II was used to assess the severity of depressive symptoms in both groups. RESULTS: There was a significant relationship between female orgasmic disorder and ADHD and depression. The results of multiple logistic regression indicated that the highest risk of female orgasmic disorder was observed in women with ADHD (odds ratio [OR], 4.91; 95% confidence interval [CI], 2.46-9.20; P < .001), women with severe depression (OR, 2.50; 95% CI, 1.08-6.96; P = .04), and women who had sexual intercourse that focused on penetration (OR, 2.02; 95% CI, 1.03-3.98; P = .04). CLINICAL IMPLICATIONS: These findings may have important implications for the prevention and treatment of sexual disorders in women. STRENGTHS AND LIMITATIONS: This design selected all diagnosed cases of female orgasmic disorder and did not select a specific subgroup. However, some limitations must be considered. This study was conducted in a single clinic, although it should be noted that it is the main clinic for the treatment of sexual dysfunction in the country. A further limitation could be that this type of study design does not allow for statements about causality to be made. CONCLUSION: There is an increased risk of female orgasmic disorder in women with ADHD, with severe depression, and who engage in penetrative sex.

Deaths of U.S. Citizens Undergoing Cosmetic Surgery - Dominican Republic, 2009-2022.

Although infections resulting from cosmetic surgery performed outside the United States have been regularly reported, deaths have rarely been identified. During 2009-2022, 93 U.S. citizens died after receiving cosmetic surgery in the Dominican Republic. The number of deaths increased from a mean of 4.1 per year during 2009-2018 to a mean of 13.0 during 2019-2022 with a peak in of 17 in 2020. A subset of post-cosmetic surgery deaths occurring during peak years was investigated, and most deaths were found to be the result of embolic events (fat emboli or venous thromboembolism) for which a high proportion of the patients who died had risk factors, including obesity and having multiple procedures performed during the same operation. These risk factors might have been mitigated or prevented with improved surgical protocols and postoperative medical care, including prophylactic measures against venous thromboembolism. U.S. citizens interested in receiving elective cosmetic surgery outside the United States should consult with their health care professionals regarding their risk for adverse outcomes. Public health authorities can support provider education on the importance of preoperative patient evaluation and the potential danger of performing multiple cosmetic procedures in one operation.

Individual and Collective Forms of Stigma Resistance: Pathways Between HIV and Sex Work Stigma and Viral Suppression Among Female Sex Workers in the Dominican Republic.

Intersecting forms of stigma including both HIV and sex work stigma have been known to impede HIV prevention and optimal treatment outcomes among FSW. Recent research has indicated that intersectional stigma can be resisted at the community and individual level. We assessed pathways between HIV stigma, sex work stigma, social cohesion and viral suppression among a cohort of 210 FSW living with HIV in the Dominican Republic. Through Poisson regression we explored the relationship between HIV outcomes and internalized, anticipated and enacted HIV and sex work stigma, and resisted sex work stigma. We employed structural equation modeling to explore the direct effect of various forms of stigma on HIV outcomes, and the mediating effects of multi-level stigma resistance including social cohesion at the community level and occupational dignity at the individual level. 76.2% of FSW were virally suppressed and 28.1% had stopped ART at least once in the last 6 months. ART interruption had a significant negative direct effect on viral suppression (OR = 0.26, p < 0.001, 95% CI: 0.13-0.51). Social cohesion had a significant positive direct effect on viral suppression (OR = 2.07, p = 0.046, 95% CI: 1.01-4.25). Anticipated HIV stigma had a significant negative effect on viral suppression (OR = 0.34, p = 0.055, 95% CI: 0.11-1.02). This effect was mediated by the interaction between cohesion and dignity which rendered the impact of HIV stigma on viral suppression not significant. Findings demonstrate that while HIV stigma has a negative impact on viral suppression among FSW, it can be resisted through individual and collective means. Results reinforce the importance of community-driven, multi-level interventions.

Deep time extinction of largest insular ant predators and the first fossil Neoponera (Formicidae: Ponerinae) from Miocene age Dominican amber.

BACKGROUND: Ponerine ants are almost exclusively predatory and comprise many of the largest known ant species. Within this clade, the genus Neoponera is among the most conspicuous Neotropical predators. We describe the first fossil member of this lineage: a worker preserved in Miocene-age Dominican amber from Hispaniola. RESULTS: Neoponera vejestoria sp. nov. demonstrates a clear case of local extinction-there are no known extant Neoponera species in the Greater Antilles. The species is attributable to an extant and well-defined species group in the genus, which suggests the group is older than previously estimated. Through CT scan reconstruction and linear morphometrics, we reconstruct the morphospace of extant and fossil ants to evaluate the history and evolution of predatory taxa in this island system. CONCLUSIONS: The fossil attests to a shift in insular ecological community structure since the Miocene. The largest predatory taxa have undergone extinction on the island, but their extant relatives persist throughout the Neotropics. Neoponera vejestoria sp. nov. is larger than all other predatory ant workers known from Hispaniola, extant or extinct. Our results empirically demonstrate the loss of a functional niche associated with body size, which is a trait long hypothesized to be related to extinction risk.

Monitoring Temporal Changes in SARS-CoV-2 Spike Antibody Levels and Variant-Specific Risk for Infection, Dominican Republic, March 2021-August 2022.

To assess changes in SARS-CoV-2 spike binding antibody prevalence in the Dominican Republic and implications for immunologic protection against variants of concern, we prospectively enrolled 2,300 patients with undifferentiated febrile illnesses in a study during March 2021-August 2022. We tested serum samples for spike antibodies and tested nasopharyngeal samples for acute SARS-CoV-2 infection using a reverse transcription PCR nucleic acid amplification test. Geometric mean spike antibody titers increased from 6.6 (95% CI 5.1-8.7) binding antibody units (BAU)/mL during March-June 2021 to 1,332 (95% CI 1,055-1,682) BAU/mL during May-August 2022. Multivariable binomial odds ratios for acute infection were 0.55 (95% CI 0.40-0.74), 0.38 (95% CI 0.27-0.55), and 0.27 (95% CI 0.18-0.40) for the second, third, and fourth versus the first anti-spike quartile; findings were similar by viral strain. Combining serologic and virologic screening might enable monitoring of discrete population immunologic markers and their implications for emergent variant transmission.

Preliminary Effects of an Urban Gardens and Peer Nutritional Counseling Intervention on HIV Treatment Adherence and Detectable Viral Load Among People with HIV and Food Insecurity: Evidence from a Pilot Cluster Randomized Controlled Trial in the Dominican Republic.

A pilot cluster randomized controlled trial involving two HIV clinics in the Dominican Republic assessed preliminary efficacy of an urban garden and peer nutritional counseling intervention. A total of 115 participants (52 intervention, 63 control) with moderate or severe food insecurity and sub-optimal antiretroviral therapy (ART) adherence and/or detectable viral load were assessed at baseline, 6- and 12-months. Longitudinal multivariate regression analysis controlling for socio-demographics and accounting for serial cluster correlation found that the intervention: reduced the prevalence of detectable viral load by 20 percentage points at 12 months; reduced any missed clinic appointments by 34 and 16 percentage points at 6 and 12 months; increased the probability of "perfect" ART adherence by 24 and 20 percentage points at 6 and 12 months; and decreased food insecurity at 6 and 12 months. Results are promising and warrant a larger controlled trial to establish intervention efficacy for improving HIV clinical outcomes.Trial registry Clinical Trials Identifier: NCT03568682.

RESUMEN: Un estudio piloto de un ensayo controlado aleatorio por conglomerados que involucró a dos clínicas del VIH en la República Dominicana evaluó de forma preliminar la eficacia de una intervención de huertos urbanos y consejería nutricional entre pares. Un total de 115 participantes (52 de intervención, 63 de control) con inseguridad alimentaria moderada o grave y con adherencia subóptima a la terapia antirretroviral (TARV) y/o carga viral detectable fueron evaluados al inicio del estudio, y a los 6 y 12 meses. El análisis de regresión longitudinal multivariada controlando por variables sociodemográficas y tomando en cuenta la correlación serial de clúster encontró que la intervención: redujo la prevalencia de carga viral detectable en 20 puntos porcentuales a los 12 meses; redujo las citas clínicas perdidas en 34 y 16 puntos porcentuales a los 6 y 12 meses; aumentó la probabilidad de adherencia "perfecta" al TARV en 24 y 20 puntos porcentuales a los 6 y 12 meses; y disminuyó la inseguridad alimentaria a los 6 y 12 meses. Los resultados son prometedores y justifican un ensayo controlado más grande para establecer la eficacia de la intervención en mejorar los resultados clínicos del VIH.

Stigma and HIV Treatment Outcomes Among Transgender Women Sex Workers in the Dominican Republic.

Trans women experience multiple forms of intersecting stigma due to trans identity, HIV, and sex work, which can negatively affect their health. There is limited understanding of the relationships between stigma and HIV care and treatment outcomes. We assessed associations between multiple forms and types of stigma and HIV treatment outcomes among trans women who conduct sex work in Santo Domingo, Dominican Republic using cross-sectional survey data. Most participants had received HIV care (91%) and were currently taking anti-retroviral therapy (ART) (84%). Only 64% were virally suppressed. Nearly one-third (32%) had interrupted ART at some point; those who had never interrupted ART were more likely to be suppressed. Drug use was associated with ART interruption. Higher enacted HIV stigma was associated with current ART use. Higher enacted HIV stigma and higher anticipated sex work stigma were associated with ART adherence. Higher trans stigma was associated with being virally suppressed. Findings highlight the importance of addressing multiple forms of stigma at the individual and clinic levels to improve and sustain viral suppression. Future research is needed to assess if unexpected associations between stigma and HIV outcomes reflect processes of resilience. Future research is also needed to assess the pathways between drug use, ART interruption, and viral suppression among trans women.

Substance Use and Depression Impede ART Adherence Among Female Sex Workers Living with HIV in the Dominican Republic.

Female sex workers (FSW) have worse HIV outcomes in part due to lower anti-retroviral therapy (ART) adherence. Substance use and depression are important barriers to ART adherence, yet few studies have assessed these relationships among FSW in longitudinal studies. Cross-Lagged Panel Models and autoregressive mediation analyses assessed substance use (illicit drug use and alcohol use disorders) in relation to ART non-adherence and the mediation role of depressive symptoms among 240 FSW living with HIV in the Dominican Republic. In annual visits (T1, T2, T3), the majority (70%, 66%, and 53%) reported at-risk drinking and 15%, 13% and 9% used illicit drug during the past 6 months. Most FSW (70%, 62% and 46%) had mild-to-severe depression. Illicit drug use predicted later ART non-adherence. This relationship was not mediated via depressive symptoms. Integrated substance use and HIV care interventions are needed to promote ART adherence and viral suppression among FSW.

RESUMEN: Las trabajadoras sexuales (TRSX) tienen peores resultados de VIH debido en parte a la menor adherencia a la terapia antirretroviral (TAR). El uso de sustancias y la depresión son barreras importantes para la adherencia; sin embargo, pocos estudios longitudinales han evaluado estas relaciones entre las TRSX. Utilizamos modelos de panel y análisis de mediación para evaluar el uso de sustancias en relación a la falta de adherencia al TAR y el papel de mediación de los síntomas depresivos entre 240 TRSX con VIH en la República Dominicana. En visitas anuales (T1, T2, T3), la mayoría (70%, 66%, and 53%) reportó consumo riesgoso de alcohol y 15%, 13% y 9% consumieron alguna droga ilícita durante los últimos 6 meses. La mayoría (70%, 62% y 46%) tenían depresión leve a grave. El uso de drogas ilícitas predijo la falta de adherencia al TAR. Esta relación no fue mediada por síntomas depresivos. Se necesitan intervenciones integradas de atención del VIH y el uso de sustancias para promover la adherencia al TAR y la supresión viral entre TRSX.

Exploring the natural history of intrinsic capacity impairments: longitudinal patterns in the 10/66 study.

BACKGROUND: intrinsic capacity (IC) is a construct encompassing people's physical and mental abilities. There is an implicit link amongst IC domains: cognition, locomotion, nutrition, sensory and psychological. However, little is known about the integration of the domains. OBJECTIVES: to investigate patterns in the presentation and evolution of IC domain impairments in low-and-middle-income countries and if such patterns were associated with adverse outcomes. METHODS: secondary analyses of the first two waves of the 10/66 study (population-based surveys conducted in eight urban and four rural catchment areas in Cuba, Dominican Republic, Puerto Rico, Venezuela, Peru, Mexico and China). We applied latent transition analysis on IC to find latent statuses (latent clusters) of IC domain impairments. We evaluated the longitudinal association of the latent statuses with the risk of frailty, disability and mortality, and tested concurrent and predictive validity. RESULTS: amongst 14,923 participants included, the four latent statuses were: high IC (43%), low deterioration with impaired locomotion (17%), high deterioration without cognitive impairment (22%), and high deterioration with cognitive impairment (18%). A total of 61% of the participants worsened over time, 35% were stable, and 3% improved to a healthier status.Participants with deteriorated IC had a significantly higher risk of frailty, disability and dementia than people with high IC. There was strong concurrent and predictive validity. (Mortality Hazard Ratio = 4.60, 95%CI 4.16; 5.09; Harrel's C = 0.73 (95%CI 0.72;0.74)). CONCLUSIONS: half of the study population had high IC at baseline, and most participants followed a worsening trend. Four qualitatively different IC statuses or statuses were characterised by low and high levels of deterioration associated with their risk of disability and frailty. Locomotion and cognition impairments showed other trends than psychological and nutrition domains across the latent statuses.

PsicAP transdiagnostic protocol of group cognitive-behavioral training for emotional disorders in Dominican Republic: a randomized controlled trial protocol.

Emotional disorders (ED) such as anxiety, depression and somatization are extremely prevalent disorders that can affect an individual's quality of life and functionality. Primary Health Care (PHC) is the first place to identify most patients with these conditions. Mental health services in the Dominican Republic, as well as in Latin America and the Caribbean in general, are unable to provide appropriate care for most people with mental disorders. Using evidence-based treatment protocols is also crucial to make progress in helping people with ED. The PsicAP project is a group intervention that uses a transdiagnostic approach and is grounded in cognitive-behavioral techniques. The program is implemented in 7 group sessions, each lasting for one and a half hours. The program has been shown to be effective in reducing clinical symptoms, dysfunction, and in improving quality of life. It is also a non-time-intensive, low-cost treatment that is helpful for addressing EDs in a PHC context. The objective is to bring psychological treatments into PHC facilities of Dominican Republic, making them more accessible for a larger amount of the population.

"When there is no money, that is when I vomit blood": the domino effect and the unfettered lethal exploitation of Black labor on Dominican sugar plantations.

BACKGROUND: In this article, I utilize the concept of the Plantationocene as an analytical framework to generate a holistic and historical understanding of the present-day struggles of a mostly Haitian migrant workforce on sugar plantations in the Dominican Republic. METHODS: Inspired by Paul Farmer's methodology, I combine political economy, history, and ethnography approaches to interpret the experiences of sugarcane cutters across historical and contemporary iterations of colonial, post-colonial, and neo-colonial practices over the course of five centuries. RESULTS: My findings elucidate the enduring power of capitalism, implicating corporate and state elites, as the structural scaffolding for acts of racialized violence that condition the life-and-death circumstances of Black laborers on Caribbean plantations to this day. Although today's sugarcane cutters may suffer differently than their enslaved or wage labor ancestors on the plantation, I argue that an unfettered racialized pattern of lethal exploitation is sustained through the structural violence of neoliberalism that links present conditions with the colonial past. CONCLUSIONS: Ultimately, this paper contributes understandings of the plantationocene's enduring effects in the global south by demonstrating how imperialist arrangements of capitalism are not a distant memory from the colonial past but instead are present yet hidden and obscured while relocated and reanimated overseas to countries like the Dominican Republic, where American capitalists still exploit Black bodies for profit and power.

Body composition and nutritional status of school-aged Haitian children living in urban and peri-urban areas of Puerto Plata, Dominican Republic.

OBJECTIVES: This study examines body composition and nutritional status of Haitian children and adolescents living in urban and peri-urban communities in the Dominican Republic to provide estimates of stunting, underweight, overweight, and obesity for this under-researched population. METHODS: Anthropometric measures including height, weight, mid-upper arm circumference, and skinfold thicknesses (triceps and subscapular) were obtained for Kreyòl-speaking school-aged children (n  = 105, males = 51, females = 54, ages 4-17). Z-scores for height, body mass index (BMI), and upper arm muscle area by height were used to classify children's nutritional status. Variation among sex and age groups was assessed. RESULTS: Relatively low rates of stunting (4.8%) and thinness (2.9%) were identified. The total prevalence of overweight was 5.7% and 2.9% of children were classified as having obesity. Girls had a higher prevalence of overweight/obesity and risk of overweight (16.7%) than boys (3.9%, p = .033). CONCLUSIONS: The prevalence of overweight and obesity (8.6%) suggests that Haitian children in these urban and peri-urban communities are experiencing the nutrition transition. Interventions should address the development of excess weight, especially among girls, as well as persisting undernutrition and stunting.

Exploring feasibility and acceptability of an integrated urban gardens and peer nutritional counselling intervention for people with HIV in the Dominican Republic.

OBJECTIVE: Food security interventions with people living with HIV (PLHIV) are needed to improve HIV outcomes. This process evaluation of a pilot intervention involving urban gardening and peer nutritional counselling with PLHIV assesses feasibility, acceptability and implementation challenges to inform scale-up. DESIGN: Mixed methods were used, including quantitative data on intervention participation and feasibility and acceptability among participants (n 45) and qualitative data from a purposive sample of participants (n 21). Audio-recorded interviews were transcribed and coded using a codebook developed iteratively. SETTING: An HIV clinic in the northwest-central part of the Dominican Republic. RESULTS: The intervention was feasible for most participants: 84 % attended a garden workshop and 71 % established an urban garden; 91 % received all three core nutritional counselling sessions; and 73 % attended the cooking workshop. The intervention was also highly acceptable: nearly, all participants (93-96 %) rated the gardening as 'helpful' or 'very helpful' for taking HIV medications, their mental/emotional well-being and staying healthy; similarly, high percentages (89-97 %) rated the nutrition counselling 'helpful' or 'very helpful' for following a healthy diet, reducing unhealthy foods and increasing fruit/vegetable intake. Garden barriers included lack of space and animals/pests. Transportation barriers impeded nutritional counselling. Harvested veggies were consumed by participants' households, shared with neighbours and family, and sold in the community. Many emphasised that comradery with other PLHIV helped them cope with HIV-related marginalisation. CONCLUSION: An urban gardens and peer nutritional counselling intervention with PLHIV was feasible and acceptable; however, addressing issues of transportation, pests and space is necessary for equitable participation and benefit.

Mixed method evaluation of a clinic waiting room-based health education program in the Dominican Republic.

Waiting rooms provide an ideal location to disseminate health information. In this mixed-methods study, we evaluated waiting room-based health education talks at two clinics in the Dominican Republic and explored recommendations for implementing this intervention in similar settings. The talks addressed noncommunicable diseases, sexually transmitted infections, family planning and gender-based violence. We conducted pre- and posttests to assess attendees' change in knowledge and conducted semi-structured interviews with a subset of them. We conducted a semi-structured focus group with educators. Analyses included Wilcox Signed Rank Tests and McNemar tests for pre- and posttests, conventional content analysis for individual interviews and transcript coding for the focus group. Patient participants were 69.3% female aged 39.6 years (SD = 13.5) on average at one clinic (n = 127) and 100% female aged 17.4 (SD = 1.3) on average at the second clinic (n = 24). Focus group participants (n = 5) had 4.8 years (SD = 3.3) of health educator experience on average. Pre- and posttests showed significant improvement (P < 0.05) across all talks. Qualitative interviews emphasized engaging, clear and brief content delivery with visual aids. The focus group highlighted the importance of patient-centered design with culturally concordant delivery and identified implementation challenges. Findings demonstrate that waiting room-based education talks improve knowledge and provide suggestions for similar interventions.

Attitudes to adolescent pregnancy among families in the Dominican Republic and El Salvador: insights from a longitudinal study.

Over the past few decades growing attention has focused on the perceived challenge of adolescent pregnancy and the need for girls to make 'smart choices'. This has generated considerable debate particularly because of the failure of many programmes and interventions to consider the structural constraints faced by young women in accessing sexual and reproductive health and rights (SRHR). Yet limited attention has been given to the views and experiences of girls' parents and caregivers, many of whom were often adolescent parents themselves. We use data from the Real Choices, Real Lives longitudinal study conducted by Plan International to consider how the experiences of girls' families shape their attitudes to teenage pregnancy in the Dominican Republic and El Salvador. Many families believe girls need to practise abstinence and avoid men and boys but given the lack of provision for SRHR faced by young women this response is not unexpected.

Power and respect in global health research collaboration: Perspectives from research partners in the United States and the Dominican Republic.

Research partnerships between institutions in the Global North and institutions in the Global South have many potential benefits, including sharing of knowledge and resources. However, such partnerships are traditionally exploitative to varying degrees. In order to promote equity in South-North research partnerships, it is necessary to learn from the experiences of researchers collaborating internationally. This study analyzed transcripts from eleven semi-structured qualitative interviews with researchers working at Clínica de Familia La Romana, an institution in the Dominican Republic with decades of experience with research and research partnerships with institutions from the Global North. The findings of this study suggest that respect for resources invested in research, as well as for the researchers and institutions themselves, are vital components to a successful global health research partnership. These findings have implications for individual research partnerships, as well as the policies of journals and institutions providing funding that affect these partnerships.

Link between Flavor Perception and Volatile Compound Composition of Dark Chocolates Derived from Trinitario Cocoa Beans from Dominican Republic.

The chemical composition of dark chocolate has a significant impact on its complex flavor profile. This study aims to investigate the relationship between the volatile chemical composition and perceived flavor of 54 dark chocolate samples made from Trinitario cocoa beans from the Dominican Republic. The samples were evaluated by a trained panel and analyzed using gas chromatography-mass spectrometry (GC-MS) to identify and quantify the volatile compounds. Predictive models based on a partial least squares regression (PLS) allowed the identification of key compounds for predicting individual sensory attributes. The models were most successful in classifying samples based on the intensity of bitterness and astringency, even though these attributes are mostly linked to non-volatile compounds. Acetaldehyde, dimethyl sulfide, and 2,3-butanediol were found to be key predictors for various sensory attributes, while propylene glycol diacetate was identified as a possible marker for red fruit aroma. The study highlights the potential of using volatile compounds to accurately predict chocolate flavor potential.

Perceptions of dental students, dental faculty, practicing dentists and industry dental professionals on the acquisition of dental competencies and clinical skills in the Dominican Republic.

INTRODUCTION: This study gathered perceptions from four stakeholder groups in the Dominican Republic (DR) regarding acquiring professional dental competencies and clinical skills. MATERIALS AND METHODS: Researcher-created surveys covering core dental competencies and clinical skills were distributed to stakeholder groups associated with nine different DR dental programs. Respondents included 153 undergraduate dental students, 153 dental faculty members, 108 practicing dentists (who had graduated in the past 5 years) and 42 industry professionals (who hire and supervise dentists). Data were examined using descriptive statistics, univariate ANOVA and multiple linear regressions. RESULTS: Dental school students and recent graduates now practicing dentists in the DR reflected moderate to solid confidence that they had learned most of the dental skills and competencies covered in the survey. Industry professionals were a bit less confident overall, while dental faculty offered the lowest scores, although those were often still in the moderately confident range. ANOVAs revealed significant differences when broken down by individual university dental programs. Regressions also revealed that individual university dental programs significantly predict confidence that dental skills and competencies were achieved. CONCLUSION: Data show that DR's dental stakeholder groups generally felt optimistic about the learning occurring. However, the lower mean scores and higher standard deviations from faculty responses raise concern, as do the significant differences between individual dental programs and the dental program itself a significant predictor. Further review of programs is needed, and a national set of dental competencies should be considered in this country.

A Two-stage Approach for Rapid Assessment of the Proportion Achieving Viral Suppression Using Routine Clinical Data.

BACKGROUND: Improving viral suppression among people with HIV reduces morbidity, mortality, and transmission. Accordingly, monitoring the proportion of patients with a suppressed viral load is important to optimizing HIV care and treatment programs. But viral load data are often incomplete in clinical records. We illustrate a two-stage approach to estimate the proportion of treated people with HIV who have a suppressed viral load in the Dominican Republic. METHODS: Routinely collected data on viral load and patient characteristics were recorded in a national database, but 74% of patients on treatment at the time of the study did not have a recent viral load measurement. We recruited a subset of these patients for a rapid assessment that obtained additional viral load measurements. We combined results from the rapid assessment and main database using a two-stage weighting approach and compared results to estimates obtained using standard approaches to account for missing data. RESULTS: Of patients with recent routinely collected viral load data, 60% had a suppressed viral load. Results were similar after applying standard approaches to account for missing data. Using the two-stage approach, we estimated that 77% (95% confidence interval [CI] = 74, 80) of those on treatment had a suppressed viral load. CONCLUSIONS: When assessing the proportion of people on treatment with a suppressed viral load using routinely collected data, applying standard approaches to handle missing data may be inadequate. In these settings, augmenting routinely collected data with data collected through sampling-based approaches could allow more accurate and efficient monitoring of HIV treatment program effectiveness.
