Hepatocellular carcinoma risk in sub-Saharan African and Afro-Surinamese individuals with chronic hepatitis B living in Europe.

BACKGROUND & AIMS: Sub-Saharan African (SSA) ethnicity has been associated with a higher risk of hepatocellular carcinoma (HCC) among individuals with chronic hepatitis B in cross-sectional studies. However, the incidence of HCC and performance of HCC risk scores in this population are unknown. METHODS: We conducted an international multicenter retrospective cohort study of all consecutive HBV-monoinfected individuals of SSA or Afro-Surinamese (AS) ethnicity managed at sites in the Netherlands, the United Kingdom and Spain. We assessed the 5- and 10-year cumulative incidences of HCC in the overall study population, among different clinically relevant subgroups and across (m)PAGE-B subgroups. Next, we explored the different risk factors for HCC. RESULTS: During a median follow-up of 8 years, we analyzed 1,473 individuals of whom 34 developed HCC. The 5- and 10-year cumulative incidences of HCC were 1% and 2.4%. The 10-year cumulative incidence of HCC was 0.7% among individuals without advanced fibrosis at baseline, compared to 12.1% among individuals with advanced fibrosis (p <0.001). Higher age (adjusted hazard ratio [aHR] 1.05), lower platelet count (aHR 0.98), lower albumin level (aHR 0.90) and higher HBV DNA log10 (aHR 1.21) were significantly associated with HCC development. The 10-year cumulative incidence of HCC was 0.5% among individuals with a low PAGE-B score, compared to 2.9% in the intermediate- and 15.9% in the high-risk groups (p <0.001). CONCLUSIONS: In this unique international multicenter cohort of SSA and AS individuals with chronic hepatitis B, we observed 5- and 10-year cumulative HCC risks of 1% and 2.4%, respectively. The risk of HCC was negligible for individuals without advanced fibrosis at baseline, and among individuals with low baseline (m)PAGE-B scores. These findings can be used to guide HCC surveillance strategies. IMPACT AND IMPLICATIONS: Sub-Saharan African ethnicity has been associated with a higher risk of hepatocellular carcinoma among individuals with chronic hepatitis B. In this international multicenter cohort study of sub-Saharan African and Afro-Surinamese individuals living with chronic hepatitis B in Europe, we observed 5- and 10-year cumulative incidences of hepatocellular carcinoma of 1% and 2.4%, respectively. The risk was negligible among individuals without advanced fibrosis and a low baseline (m)PAGE-B score. These findings can be used to guide HCC surveillance strategies in this population.

Prevalence of musculoskeletal complaints and health-related quality of life in a Maroon and Kalinya Indigenous rural village in Suriname.

PURPOSE: Musculoskeletal complaints (MSCs), a leading contributor to disability worldwide, have a major impact on health-related quality of life (HRQoL). Poor general health related to lifestyle factors such as smoking, alcohol consumption and physical inactivity can lead to a higher risk to suffer MSCs. For minority groups in Suriname such as the Maroons and the Indigenous peoples no research has been conducted regarding prevalence of MSCs, HRQoL and various lifestyle factors. The aims were to determine the prevalence of MSCs and HRQoL in two rural tribal villages in the forested interior of Suriname and to identify various lifestyle factors associated with HRQoL in these communities. METHOD: This was a cross-sectional community-based study using the Community Oriented Program for the Control of Rheumatic Diseases stage 1, phase 1 & 2 methodology in Goejaba, a Maroon village and Galibi, an Indigenous rural village. Sociodemographic data, self-reported comorbidities, past MSCs (for longer than seven days), lifestyle factors including smoking, alcohol use, body mass index (BMI) and physical activity (PA), and HRQoL (using the 36-item Short Form Survey (SF-36)) data were gathered among 153 Indigenous individuals in Galibi, and 516 Maroons in Goejaba. Regression models were constructed to explore associations between presence of MSCs, lifestyle factors and HRQoL. RESULTS: High prevalence rates for past MSCs were reported in Galibi (72.4%) and Goejaba (58.3%). In both communities, respondents with MSCs reported significantly worse HRQoL than persons without MSCs. MSCs and the presence of comorbidities had a strong negative association with HRQoL, whereas PA positively influenced the physical and mental health domains of the SF-36. Smoking, alcohol use and BMI showed no association with HRQoL. CONCLUSIONS: In this first study, a high prevalence for MSCs was reported in an Indigenous and Maroon rural community in Suriname. MSCs and comorbidities had a significant negative impact on HRQoL. PA was associated with higher self-reported HRQoL.

Anticipated benefits and challenges of implementing group care in Suriname's maternity and child care sector: a contextual analysis.

BACKGROUND: Suriname is a uppermiddle-income country with a relatively high prevalence of preventable pregnancy complications. Access to and usage of high-quality maternity care services are lacking. The implementation of group care (GC) may yield maternal and child health improvements. However, before introducing a complex intervention it is pivotal to develop an understanding of the local context to inform the implementation process. METHODS: A context analysis was conducted to identify local needs toward maternity and postnatal care services, and to assess contextual factor relevant to implementability of GC. During a Rapid Qualitative Inquiry, 63 online and face-to-face semi-structured interviews were held with parents, community members, on-and off-site healthcare professionals, policy makers, and one focus group with parents was conducted. Audio recordings were transcribed in verbatim and analysed using thematic analysis and Framework Method. The Consolidated Framework for Implementation Research served as a base for the coding tree, which was complemented with inductively derived codes. RESULTS: Ten themes related to implementability, one theme related to sustainability, and seven themes related to reaching and participation of the target population in GC were identified. Factors related to health care professionals (e.g., workload, compatibility, ownership, role clarity), to GC, to recipients and to planning impact the implementability of GC, while sustainability is in particular hampered by sparse financial and human resources. Reach affects both implementability and sustainability. Yet, outer setting and attitudinal barriers of health professionals will likely affect reach. CONCLUSIONS: Multi-layered contextual factors impact not only implementability and sustainability of GC, but also reach of parents. We advise future researchers and implementors of GC to investigate not only determinants for implementability and sustainability, but also those factors that may hamper, or facilitate up-take. Practical, attitudinal and cultural barriers to GC participation need to be examined. Themes identified in this study will inspire the development of adaptations and implementation strategies at a later stage.

Dengue, chikungunya and Zika virus infections among Dutch travellers to Suriname: a prospective study during the introduction of chikungunya and Zika virus, 2014 to 2017.

BackgroundSuriname, a country endemic for dengue virus (DENV), is a popular destination for Dutch travellers visiting friends and relatives and tourist travellers. Chikungunya and Zika virus (CHIKV, ZIKV) were introduced in 2014 and 2015, respectively. Data on infection risks among travellers are limited.AimWe aimed to prospectively study incidence rate (IR) and determinants for DENV, ZIKV and CHIKV infection in adult travellers to Suriname from 2014 through 2017.MethodsParticipants kept a travel diary and were tested for anti-DENV, anti-ZIKV and anti-CHIKV IgG antibodies (Euroimmun). Selected samples were subjected to an in-house DENV and ZIKV PRNT50. The IR (infections/1,000 person-months of travel) and IR ratio and determinants for infection were calculated.ResultsTravel-acquired infections were found in 21 of 481 participants: 18 DENV, four ZIKV and two CHIKV, yielding an IRDENV of 47.0 (95% CI: 29.6-74.6), IRZIKV of 11.6 (95% CI: 4.4-31.0) and IRCHIKV of 5.6 (95% CI: 1.4-22.2)/1,000 person-months. In nine DENV and three ZIKV infected participants, infections were PRNT50-confirmed, yielding a lower IRDENV of 23.3 (95% CI: 12.1-44.8) and an IRZIKV of 8.4 (95% CI: 2.7-26.1) per 1,000 person-months. Tourist travel was associated with DENV infection. ZIKV and CHIKV infections occurred soon after their reported introductions.ConclusionsDespite an overestimation of serologically confirmed infections, Dutch travellers to Suriname, especially tourists, are at substantial risk of DENV infection. As expected, the risk of contracting ZIKV and CHIKV was highest during outbreaks. Cross-reaction and potential cross-protection of anti-DENV and -ZIKV antibodies should be further explored.

Evaluating elimination of mother-to-child transmission of HIV in Suriname: a mixed method study.

Objectives: To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants. Methods: A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15-49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed. Results: In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6-215.3) and the child (OR 145.7, 95% CI 14.4-1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4-0.7) compared with urban living. Conclusions: HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

Factors associated with COVID-19 length of hospitalization and mortality during four epidemic waves, March 2020-November 2021, Suriname.

Objectives: To determine the sociodemographic risk factors associated with coronavirus disease 2019 (COVID-19) mortality in Suriname. Methods: This was a retrospective cohort study. All registered deaths from COVID-19 in Suriname (n=1112) between March 13, 2020 and November 11, 2021 were included. Data were collected from medical records and included demographic variables and hospitalization duration of patients who died. Descriptive statistics, chi-squared tests, ANOVA models, and logistic regression analyses were used to determine associations between sociodemographic variables, length of hospitalization, and mortality during four epidemic waves. Results: The case fatality rate over the study period was 22 per 1 000 population. The first epidemic wave was from July to August 2020, the second from December 2020 to January 2021, the third from May to June 2021, and the fourth from August to September 2021. Significant differences were found in the number of deaths and hospitalization duration by wave (p<0.001). Patients were more likely to have a longer hospitalization during the first (OR 1.66; 95% CI: 0.98, 2.82) and third waves (OR 2.37; 95% CI: 1.71, 3.28) compared with the fourth wave. Significant differences in mortality were also seen between ethnicities by wave (p=0.010). Compared with the mixed and other group, people of Creole ethnicity (OR 2.7; 95% CI: 1.33, 5.29) and Tribal people (OR 2.8; 95% CI: 1.12, 7.02) were more likely to die during the fourth wave than the third wave. Conclusions: Tailored interventions are needed for males, people of Creole descent, Tribal and Indigenous peoples, and people older than 65 years.

Prevalence of persistent symptoms after having COVID-19 in a cohort in Suriname.

Objectives: To determine the prevalence of persistent symptoms after having coronavirus disease 2019 (COVID-19) in a cohort in Suriname, and assess the factors associated with long COVID. Methods: A sample of adults 18 years and older who were registered 3-4 months previously in a national database because of a positive COVID-19 test were selected. They were interviewed about socioeconomic characteristics, pre-COVID-19 health status and lifestyle, and symptoms during and after COVID-19. A subset of participants underwent a physical examination to determine body mass index, waist circumference, cardiovascular parameters, lung function, and functionality. Results: A total of 106 participants (mean age 49 (standard deviation 15) years; 62.3% female) were interviewed, of whom 32 were physically examined. The greatest proportion of participants was of Hindustani descent (22.6%). Overall, 37.7% of participants were physically inactive, 26.4% had hypertension or diabetes mellitus, and 13.2% had been previously diagnosed with heart disease. Most participants (56.6%) had experienced mild COVID-19 and 14.2% had experienced severe COVID-19. A large proportion (39.6%) had experienced at least one persistent symptom after recovery from acute COVID-19 and more women were affected (47.0% of women versus 27.5% of men). Fatigue and alopecia were the most common symptoms, followed by dyspnea and sleep disturbance. Differences were observed between ethnic groups. Based on physical examination, 45.0% of the subset was obese and 67.7% had very high waist-circumference. Conclusions: About 40% of the cohort had at least one persistent symptom 3-4 months after having had COVID-19, with differences observed by sex and ethnic group.

Ethnic Culture as Related to Sexual and Reproductive Behavior in the Republic of Suriname: The Pervasiveness of Culture.

We examined the effects of culture and ethnicity on life history strategies in terms of sexual and reproductive behaviors. The sample included 500 adults, aged 25-50 years, from the five major ethnic groups in Suriname, i.e., the Maroons, Creoles, Hindustani, Javanese, and Mixed. First, there were strong gender differences: men reported to have had more sex partners and to have had their first sexual experience earlier than women, whereas women had their first child earlier and had more children than men. Second, in general, ethnicity affected life history substantially. The Maroons stood out by a relatively fast life history: they reported to have had more sexual partners, to have had their first sex and first child at an earlier age, and to have more children than all other groups. The Creoles were in general similar to the Maroons, whereas the Hindustani and the Javanese were characterized by a relatively slow life history: they reported to have had the lowest number of sexual partners, to have had their first sex and first child at the latest age, and to have had the lowest number of children. The differences between the ethnic groups were upheld when controlling for income, educational level, and father absence during childhood. A lower education was associated with reporting to have had one's first sex as well as one's first child at a younger age and children who grew up without a father reported to have had their first sex at a younger age.

Influence of perceived stress on prenatal depression in Surinamese women enrolled in the CCREOH study.

BACKGROUND: Prenatal depression may have adverse health effects on mothers and their offspring. Perceived stress is an important risk factor for depression during pregnancy. Studies have shown that both perceived stress and depression may negatively influence birth outcomes. While 20% of pregnancies in Suriname, a middle-income Caribbean country located in northern South America, results in adverse birth outcomes, data on prenatal depression and its risk factors are lacking. This study aimed to assess the influence of perceived stress on depression during pregnancy in Surinamese women. METHODS: Survey data were used from 1143 pregnant women who participated in the Caribbean Consortium for Research in Environmental and Occupational Health-MeKiTamara prospective cohort study that addresses the impact of chemical and non-chemical environmental exposures in mother/child dyads in Suriname. The Edinburgh Depression Scale and Cohen Perceived Stress Scale were used to screen for probable depression (cut-off ≥ 12) and high stress (cut-off ≥ 20), respectively. The association between perceived stress and depression was examined using bivariate and multiple logistic regression analyses, adjusted for social support (including resilience) and maternal demographics. RESULTS: The prevalence of high perceived stress during the first two trimesters and the third trimester were 27.2% and 24.7% respectively. 22.4% of the participants had probable depression during first or second trimester and 17.6% during the third trimester. Women experiencing high stress levels during the first two trimesters had 1.92 increased odds (95% CI 1.18-3.11, p = 0.008) of having probable depression during the third trimester of pregnancy than those with low stress levels. Pregnant women with low individual resilience during early pregnancy (52.1%) had 1.65 (95% CI 1.03-2.63, p = 0.038) increased odds of having probable depression during later stages of pregnancy compared to those with high individual resilience. Low educational level (p = 0.004) and age of the mother (20-34 years) (p = 0.023) were significantly associated with probable depression during the third trimester. CONCLUSIONS: Early detection and management of stress and depression during pregnancy are important. Health education programs, targeting the reduction of stress during pregnancy, may help to reduce depression and its potential adverse health effects on the mother and child.

Depression during pregnancy may lead to adverse health effects in mothers and children. While one in five pregnancies resulted in an adverse birth outcome in Suriname, and perceived stress and depression are important risk factors for birth outcomes, data on depression and its risk factors are lacking. This study aimed to determine the association between perceived stress and prenatal depression in Surinamese pregnant women participating in the Caribbean Consortium for Research in Environmental and Occupational Health-MeKiTamara study.A total of 1143 pregnant women were included in the study. Using questionnaires, data was collected on demographic factors, perceived stress, social support (including resilience), and probable depression.Perceived stress was somewhat higher during the first two trimesters (27.2%), than the third trimester (24.7%). This was also the case for probable depression; higher during the first two trimesters (22.4%) than during the third trimester (17.6%). The study found a statistically significant association of high perceived stress, low perceived individual resilience, lower education and older maternal age with probable depression during pregnancy.Early detection and effective management of perceived stress and depression during pregnancy are very important. There is a need for prenatal clinics in Suriname to routinely screen for symptoms of perceived stress and depression to minimize the potential impact on mother and child. Health education programs, targeting the reduction of stress during pregnancy, may help to reduce depression and its potential adverse health effects on the mother and child.

Serum Levels of Markers of Endothelial Activation Are Not Associated with a Positive Blood Culture in Surinamese Children with Suspected Severe Infection.

BACKGROUND: Systemic serum levels of markers of endothelial activation are associated with infection. We hypothesize that levels of markers of endothelial activation are associated with the presence of a positive blood culture as a manifestation of a systemic infection in children with a suspected severe infection in Suriname. METHODS: In this prospective observational cohort study, children between 1 month and 18 years of age suspected of severe infection as assessed by the threating physician, and in whom laboratory testing and blood culturing was performed before start of intravenous antibiotic treatment, were recruited at the emergency department of the Academic Hospital Paramaribo, Suriname. Serum was collected at blood culturing and after 48-72 h of admission. Serum was stored for measurement of levels of Angiopoietin (Ang)-1, Ang-2, soluble (s)P-selectin, sE-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1 and platelet and endothelial cell adhesion molecule-1. RESULTS: Fifty-one children were included of whom 10 had a positive blood culture. Baseline characteristics were similar between children with and without a positive blood culture. No significant differences in serum levels of the Angiopoietins or soluble cellular adhesion molecules between groups were observed at start of antibiotic treatment nor after 48-72 h. CONCLUSIONS: The data from this study indicate that in children with severe infection, serum levels of markers of endothelial cell activation are not associated with a positive blood culture. Thus, having a positive bacterial blood culture may not be the only factor driving endothelial activation in this patient population.

Toward Inclusive Landscape Governance in Contested Landscapes: Exploring the Contribution of Participatory Tools in the Upper Suriname River Basin.

Nowadays, tropical forest landscapes are commonly characterized by a multitude of interacting institutions and actors with competing land-use interests. In these settings, indigenous and tribal communities are often marginalized in landscape-level decision making. Inclusive landscape governance inherently integrates diverse knowledge systems, including those of indigenous and tribal communities. Increasingly, geo-information tools are recognized as appropriate tools to integrate diverse interests and legitimize the voices, values, and knowledge of indigenous and tribal communities in landscape governance. In this paper, we present the contribution of the integrated application of three participatory geo-information tools to inclusive landscape governance in the Upper Suriname River Basin in Suriname: (i) Participatory 3-Dimensional Modelling, (ii) the Trade-off! game, and (iii) participatory scenario planning. The participatory 3-dimensional modelling enabled easy participation of community members, documentation of traditional, tacit knowledge and social learning. The Trade-off! game stimulated capacity building and understanding of land-use trade-offs. The participatory scenario planning exercise helped landscape actors to reflect on their own and others' desired futures while building consensus. Our results emphasize the importance of systematically considering tool attributes and key factors, such as facilitation, for participatory geo-information tools to be optimally used and fit with local contexts. The results also show how combining the tools helped to build momentum and led to diverse yet complementary insights, thereby demonstrating the benefits of integrating multiple tools to address inclusive landscape governance issues.

Malaria serology data from the Guiana shield: first insight in IgG antibody responses to Plasmodium falciparum, Plasmodium vivax and Plasmodium malariae antigens in Suriname.

BACKGROUND: Suriname has accomplished a steep decline in malaria burden, even reaching elimination levels. Plasmodium serology data are not available for Suriname and even extremely scarce within the region, therefore malaria serology testing was introduced, country customized cut-off values were determined and a study was performed to explore the antibody status for Plasmodium falciparum, Plasmodium vivax and Plasmodium malariae. METHODS: A cross-sectional survey was conducted between July 2017 and March 2018 in two areas of the interior with different malaria settings: Stoelmanseiland, representing Maroon villages and Benzdorp, a gold mining area, with mostly Brazilian miners. Dried blood spots (DBS) were collected (n = 197) and antibody presence against seven Plasmodium antigens was detected using a multiplex bead-based, IgG antibody assay. Demographic information was gathered through a questionnaire. Country customized cut-off values were generated from a Surinamese malaria-naïve reference population (n = 50). RESULTS: Serological analysis for the reference population revealed cut-off values ranging from 14 MFI for LSA-1 to 177 MFI for PmMSP-119. Seroprevalence against any of the three MSP-119 antibodies was similar in both regions and surpassed 75%. Single seropositivity against PfMSP-119 antibodies was higher in Stoelmanseiland (27.0%) than Benzdorp (9.3%), in line with the historical malaria burden of Stoelmanseiland, while the reverse was observed for PvMSP-119 antibodies. Despite sporadic reports of P. malariae infections, PmMSP-119 antibody presence was 39.6%. A more detailed examination of P. falciparum serology data displayed a higher seroprevalence in villagers (90.7%) than in Brazilians (64.6%) and a highly diverse antigenic response with 22 distinct antibody combinations. CONCLUSIONS: The results on the malaria antibody signature of Maroon villagers and Brazilian miners living in Suriname displayed a high Plasmodium seroprevalence, especially for P. falciparum in villagers, still reflecting the historical malaria burden. The seroprevalence data for both regions and the observed combinations of P. falciparum antibodies provided a valuable dataset from a historically important region to the international malaria serology knowledge. First insight in malaria serology data for Suriname indicated that the use of other target groups and assessment of age-dependent seroprevalence are required to successfully use malaria serology as tool in the national elimination strategy.

Infectious pseudo-aneurysm of the left ventricle: a case report and a review of the literature.

BACKGROUND: In the workup of a pediatric patient with pericarditis we found evidence of a pseudo-aneurysm of the left ventricle, which is a rare complication of purulent pericarditis. CASE PRESENTATION: We present a case of a six-year-old girl who was diagnosed with pericarditis and a fistula between the pericardial and the intra-luminal space of the left ventricle of the heart. She was successfully treated with antibiotics and cardio-thoracic surgery. We found 23 published cases (21 with follow-up) of infectious pseudo-aneurysm of the heart, of which 19 underwent surgery, 5 had fatal outcome, and 2 who refused surgery survived. The majority of cases were associated with Staphylococcus aureus. The exact mechanisms of this rare complication remain unknown. CONCLUSIONS: A pseudo-aneurysm of the left ventricle is a rare and not well understood complication of a purulent pericarditis most commonly caused by Staphylococcus aureus infection. Because of risk of rupture, surgical intervention is advised.

Adequate antenatal care and ethnicity affect preterm birth in pregnant women living in the tropical rainforest of Suriname.

BACKGROUND: Adequate antenatal care (ANC) services are key for early identification of pregnancy related risk factors and maintaining women's health during pregnancy. This study aimed to assess the influence of ANC provided by the Medical Mission Primary Health Care Suriname (MMPHCS) and of ethnicity on adverse birth outcomes in Tribal and Indigenous women living in Suriname's remote tropical rainforest interior. METHOD: From April 2017 to December 2018 eligible Tribal and Indigenous women with a singleton pregnancy that received ANC from MMPHCS were included in the study. Data on low birth weight (LBW < 2500 g), preterm birth (PTB < 37 weeks), low Apgar score (< 7 at 5 min), parity (≤1 vs. > 1) and antenatal visits utilization (≥8 vs. < 8) in 15 interior communities were retrospectively analyzed using descriptive statistics, crosstabs and Fisher's exact tests. RESULTS: A total of 204 women were included, 100 (49%) were Tribal, mean age was 26 ± 7.2 years and 126 women (62%) had 8 or more ANC visits. One participant had a miscarriage; 22% had adverse birth outcomes: 16 (7.9%) LBW and 30 (14.8%) PTB; 7 women had a child with both PTB and LBW; 5 women had stillbirths. None of the newborns had low Apgar scores. Maternal age, ethnicity, ANC and parity were associated with PTB (χ2 = 8,75, p = 0.003, χ2 = 4,97, p = 0.025, χ2 = 17,45, p < 0.001, χ2 = 11,93, p < 0.001 respectively). CONCLUSION: Despite an almost 100% study adherence over one fifth of women that received ANC in the interior of Suriname had adverse birth outcomes, in particular PTB and LBW. Younger nulliparous Indigenous women with less than the recommended 8 ANC visits had a higher risk for PTB. The rate of adverse birth outcomes highlights the need for further research to better assess factors influencing perinatal outcomes and to put strategies in place to improve perinatal outcomes. Exposure assessment of this sub-cohort and neurodevelopment testing of their children is ongoing and will further inform on potential adverse health effects associated with environmental exposures including heavy metals such as mercury and lead.

Childbirth outcomes and ethnic disparities in Suriname: a nationwide registry-based study in a middle-income country.

BACKGROUND: Our study aims to evaluate the current perinatal registry, analyze national childbirth outcomes and study ethnic disparities in middle-income country Suriname, South America. METHODS: A nationwide birth registry study was conducted in Suriname. Data were collected for 2016 and 2017 from the childbirth books of all five hospital maternity wards, covering 86% of all births in the country. Multinomial regression analyses were used to assess ethnic disparities in outcomes of maternal deaths, stillbirths, teenage pregnancy, cesarean delivery, low birth weight and preterm birth with Hindustani women as reference group. RESULTS: 18.290 women gave birth to 18.118 (98%) live born children in the five hospitals. Hospital-based maternal mortality ratio was 112 per 100.000 live births. Hospital-based late stillbirth rate was 16 per 1000 births. Stillbirth rate was highest among Maroon (African-descendent) women (25 per 1000 births, aOR 2.0 (95%CI 1.3-2.8) and lowest among Javanese women (6 stillbirths per 1000 births, aOR 0.5, 95%CI 0.2-1.2). Preterm birth and low birthweight occurred in 14 and 15% of all births. Teenage pregnancy accounted for 14% of all births and was higher in Maroon women (18%) compared to Hindustani women (10%, aOR 2.1, 95%CI 1.8-2.4). The national cesarean section rate was 24% and was lower in Maroon (17%) than in Hindustani (32%) women (aOR 0.5 (95%CI 0.5-0.6)). Cesarean section rates varied between the hospitals from 17 to 36%. CONCLUSION: This is the first nationwide comprehensive overview of maternal and perinatal health in a middle income country. Disaggregated perinatal health data in Suriname shows substantial inequities in outcomes by ethnicity which need to be targetted by health professionals, researchers and policy makers.

A SARS-CoV-2 Surveillance System in Sub-Saharan Africa: Modeling Study for Persistence and Transmission to Inform Policy.

BACKGROUND: Since the novel coronavirus emerged in late 2019, the scientific and public health community around the world have sought to better understand, surveil, treat, and prevent the disease, COVID-19. In sub-Saharan Africa (SSA), many countries responded aggressively and decisively with lockdown measures and border closures. Such actions may have helped prevent large outbreaks throughout much of the region, though there is substantial variation in caseloads and mortality between nations. Additionally, the health system infrastructure remains a concern throughout much of SSA, and the lockdown measures threaten to increase poverty and food insecurity for the subcontinent's poorest residents. The lack of sufficient testing, asymptomatic infections, and poor reporting practices in many countries limit our understanding of the virus's impact, creating a need for better and more accurate surveillance metrics that account for underreporting and data contamination. OBJECTIVE: The goal of this study is to improve infectious disease surveillance by complementing standardized metrics with new and decomposable surveillance metrics of COVID-19 that overcome data limitations and contamination inherent in public health surveillance systems. In addition to prevalence of observed daily and cumulative testing, testing positivity rates, morbidity, and mortality, we derived COVID-19 transmission in terms of speed, acceleration or deceleration, change in acceleration or deceleration (jerk), and 7-day transmission rate persistence, which explains where and how rapidly COVID-19 is transmitting and quantifies shifts in the rate of acceleration or deceleration to inform policies to mitigate and prevent COVID-19 and food insecurity in SSA. METHODS: We extracted 60 days of COVID-19 data from public health registries and employed an empirical difference equation to measure daily case numbers in 47 sub-Saharan countries as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R. RESULTS: Kenya, Ghana, Nigeria, Ethiopia, and South Africa have the most observed cases of COVID-19, and the Seychelles, Eritrea, Mauritius, Comoros, and Burundi have the fewest. In contrast, the speed, acceleration, jerk, and 7-day persistence indicate rates of COVID-19 transmissions differ from observed cases. In September 2020, Cape Verde, Namibia, Eswatini, and South Africa had the highest speed of COVID-19 transmissions at 13.1, 7.1, 3.6, and 3 infections per 100,0000, respectively; Zimbabwe had an acceleration rate of transmission, while Zambia had the largest rate of deceleration this week compared to last week, referred to as a jerk. Finally, the 7-day persistence rate indicates the number of cases on September 15, 2020, which are a function of new infections from September 8, 2020, decreased in South Africa from 216.7 to 173.2 and Ethiopia from 136.7 to 106.3 per 100,000. The statistical approach was validated based on the regression results; they determined recent changes in the pattern of infection, and during the weeks of September 1-8 and September 9-15, there were substantial country differences in the evolution of the SSA pandemic. This change represents a decrease in the transmission model R value for that week and is consistent with a de-escalation in the pandemic for the sub-Saharan African continent in general. CONCLUSIONS: Standard surveillance metrics such as daily observed new COVID-19 cases or deaths are necessary but insufficient to mitigate and prevent COVID-19 transmission. Public health leaders also need to know where COVID-19 transmission rates are accelerating or decelerating, whether those rates increase or decrease over short time frames because the pandemic can quickly escalate, and how many cases today are a function of new infections 7 days ago. Even though SSA is home to some of the poorest countries in the world, development and population size are not necessarily predictive of COVID-19 transmission, meaning higher income countries like the United States can learn from African countries on how best to implement mitigation and prevention efforts.

Zika Virus Seroprevalence in Urban and Rural Areas of Suriname, 2017.

In 2015-2016, a Zika virus (ZIKV) outbreak occurred in the Americas. In 2017, we conducted a ZIKV serosurvey in Suriname in which 770 participants were recruited from 1 urban area and 2 rural villages in the tropical rainforest. All collected samples were tested for presence of ZIKV antibodies using a ZIKV immunoglobulin G enzyme-linked immunosorbent assay and a virus neutralization assay. We found that 35.1% of the participants had neutralizing antibodies against ZIKV. In 1 remote village in the rainforest, 24.5% of the participants had neutralizing antibodies against ZIKV, suggesting that ZIKV was widely spread across Suriname.

Not-knowing and the proliferation of assumptions: local explanations of Cutaneous Leishmaniasis in Suriname.

Why do patients and others confronted with cutaneous leishmaniasis (CL) - a parasitic skin disease - in the hinterland of Suriname, South America, provide a dazzling variety of aetiological explanations for one single illness? And how do these explanations reflect local knowledge of and interest in the origin of illness? In this article, we explore these questions using the concept of 'not-knowing', as introduced by Murray Last in 1981. One of Last's conclusions is that 'don't knows' or 'don't cares' reflect people's disinterest in medicine. The aim of this article, however, is to draw attention to another aspect of not-knowing: it may lead to a proliferation of explanatory assumptions, unhindered by precise knowledge. In other words, multiple explanations mask not-knowing, which is from a methodological point of view a rarely observed element in social science research and constitutes an important addition to Murray Last's well known argument. The paper describes findings based on anthropological fieldwork carried out between September 2009 and December 2010 at the Dermatology Service in Suriname's capital Paramaribo and among 205 CL patients and 321 inhabitants in various communities in the hinterland. As this article shows, both knowing and not-knowing are rooted in the various contexts of people's daily lives and reflect their historical, socio-cultural, occupational, educational, biological, environmental, and public health-related conditions. Public health authorities should explore not-knowing more seriously in their efforts to prevent illness, since knowing about not-knowing is valuable in the design of health education and prevention programmes.

Metal and metalloid levels in blood of semipalmated sandpipers (Calidris pusilla) from Brazil, Suriname, and Delaware Bay: Sentinels of exposure to themselves, their prey, and predators that eat them.

Identifying animals as sentinels for humans and other animal species is an excellent method for understanding exposure to environmental contamination at different times and places. Shorebirds are useful sentinels because they have a world-wide distribution, eat a range of prey, and are eaten by a range of other species, including humans. We collected blood from semipalmated sandpipers (Calidris pusilla) wintering in northern (Suriname N = 71) and northeastern (Brazil N = 61) South America to examine levels of heavy metals and metalloids (arsenic, selenium), and compare them to blood levels in sandpipers at a heavily used stopover site in New Jersey (N = 30; Delaware Bay, NJ). Since blood represents relatively recent exposure, it can provide information on where and when the birds were exposed. Levels were highest in Brazil for arsenic and particularly selenium; highest in Suriname for cadmium and lead; and highest in New Jersey for chromium. Samples from Brazil and Suriname presented higher levels of mercury than did those from New Jersey. There were no geographic differences for cobalt. Levels of all metals were generally within an order of magnitude. The significant geographic difference for selenium was interesting because it is regulated in the body. Selenium levels in the NJ sample were directly proportional to levels found in their principle food at this migration stopover site (eggs of horseshoe crab, Limulus polyphemus). Mean selenium level was almost an order of magnitude higher in the semipalmated sandpiper blood samples from Brazil (mean of 27,500 µg/L= ppb) compared to the other sampling locations (mean > 5330 µg/L). This is a toxic level and cause for concern and further investigation, alerting us to look for other evidence of excess selenium exposure. Otherwise the levels of other metals are generally not high enough to cause harm to the sandpipers themselves or to predators that eat them. We discuss the implications for these birds and their exposure to contaminants at different stopover sites.

Bottom-up development of national obstetric guidelines in middle-income country Suriname.

BACKGROUND: Obstetric guidelines are useful to improve the quality of care. Availability of international guidelines has rapidly increased, however the contextualization to enhance feasibility of implementation in health facilities in low and middle-income settings has only been described in literature in a few instances. This study describes the approach and lessons learned from the 'bottom-up' development process of context-tailored national obstetric guidelines in middle-income country Suriname. METHODS: Local obstetric health care providers initiated the guideline development process in Suriname in August 2016 for two common obstetric conditions: hypertensive disorders of pregnancy (HDP) and post partum haemorrhage (PPH). RESULTS: The process consisted of six steps: (1) determination of how and why women died, (2) interviews and observations of local clinical practice, (3) review of international guidelines, (4) development of a primary set of guidelines, (5) initiation of a national discussion on the guidelines content and (6) establishment of the final guidelines based on consensus. Maternal enquiry of HDP- and PPH-related maternal deaths revealed substandard care in 90 and 95% of cases, respectively. An assessment of the management through interviews and labour observations identified gaps in quality of the provided care and large discrepancies in the management of HDP and PPH between the hospitals. International recommendations were considered unfeasible and were inconsistent when compared to each other. Local health care providers and stakeholders convened to create national context-tailored guidelines based on adapted international recommendations. The guidelines were developed within four months and locally implemented. CONCLUSION: Development of national context-tailored guidelines is achievable in a middle-income country when using a 'bottom-up' approach that involves all obstetric health care providers and stakeholders in the earliest phase. We hope the descriptive process of guideline development is helpful for other countries in need of nationwide guidelines.
