1) Background: Elevated hepcidin levels have been linked to anemia of inflammation (AI). Retinol deficiency has shown to upregulate hepcidin expression in animals, while conflicting evidence links VD status with hepcidin concentration in humans. The purpose of the study is to explore if VA and VD status are associated with hepcidin concentrations in older Mexican adults (OA). 2) Methods: A cross-sectional study was conducted in summer 2015, using serum samples from 783 fasting OA ages 60 and above residents from Campeche and Yucatán. VA deficiency (VAD) was defined as serum retinol concentration <20 μg/dL and VD deficiency (VDD) as 25(OH)D <50 nmol/L. The log-hepcidin was the outcome variable expressed as continuous and tertiles of its distribution. Linear and ordinal regression models were used. 3) Results: VAD was present in 3.4% and VDD in 9.5% of OA. Log-retinol was inversely associated with log-hepcidin (coeff.: −0.15, 95%CI: −0.2, −0.09). VAD status shown a higher probability than non-VAD for higher hepcidin tertiles (OR = 2.15, 95%CI: 1.24, 3.74). VDD states was not associated with hepcidin in the linear (coeff.: 0.16, 95%CI: −0.02, 0.34) nor the ordinal model (OR = 0.74, 95%CI: 0.42, 1.28). 4) Conclusions: VAD, but not VDD, status was inversely associated with hepcidin concentrations in OA.

ObjectiveThe objective of the study was to examine the association between maternal healthcare utilisation and complete childhood vaccination in sub-Saharan Africa.DesignOur study was a cross-sectional study that used pooled data from 29 countries in sub-Saharan Africa.ParticipantsA total of 60 964 mothers of children aged 11–23 months were included in the study.Outcome variablesThe main outcome variable was complete childhood vaccination. The explanatory variables were number of antenatal care (ANC) visits, assistance during delivery and postnatal care (PNC).ResultsThe average prevalence of complete childhood vaccination was 85.6%, ranging from 67.0% in Ethiopia to 98.5% in Namibia. Our adjusted model, children whose mothers had a maximum of three ANC visits were 56% less likely to have complete vaccination, compared with those who had at least four ANC visits (adjusted OR (aOR)=0.44, 95% CI 0.42 to 0.46). Children whose mothers were assisted by traditional birth attendant/other (aOR=0.43, 95% CI 0.41 to 0.56) had lower odds of complete vaccination. The odds of complete vaccination were lower among children whose mothers did not attend PNC clinics (aOR=0.26, 95% CI 0.24 to 0.29) as against those whose mothers attended.ConclusionThe study found significant variations in complete childhood vaccination across countries in sub-Saharan Africa. Maternal healthcare utilisation (ANC visits, skilled birth delivery, PNC attendance) had significant association with complete childhood vaccination. These findings suggest that programmes, interventions and strategies aimed at improving vaccination should incorporate interventions that can enhance maternal healthcare utilisation. Such interventions can include education and sensitisation, reducing cost of maternal healthcare and encouraging male involvement in maternal healthcare service utilisation.

Background: Some studies suggest that favourable socioeconomic circumstances are associated with better parent–child relations but the documentation of such an association is limited and inconsistent. Few studies focused on infancy, few studies relied on objective measurement of parent–infant relations, and few studies included more than one measurement of parent–infant relations in the first year of life. Aims: To report the prevalence of objectively measured problems in parent–infant relations during the first year of life and to examine the association between socioeconomic circumstances and parent–infant relations in an unselected community sample of infants. Methods: Cross-sectional study of a community sample of children from birth to 10 months in 15 municipalities in Denmark, n = 11,765. The exposure variables were population register data about socioeconomic circumstances: (a) parents’ education, (b) family composition, (c) parents’ origin, and (d) parents’ occupational status. The outcome variable was the health visitor’s concerns about the parent–infant relation assessed at four home visits from birth to 10 months after delivery. Results: The proportion of children with concerns about the parent–infant relation was 10.5%, 7.8% at one home visit and 2.8% at two or more home visits. Logistic regression analyses showed that all four indicators of socioeconomic circumstances were associated with concerns about the parent–infant relation in the first year of life. Conclusions: The risk of problematic parent–infant relations were significantly elevated among, children of immigrant parents, and children of parents with shorter education and not in education or work.

Introduction: HE4 is a novel tumour biomarker used for early diagnosis of ovarian cancer. This study evaluated the diagnostic accuracy of HE4 alone and in combination with CA125, risk of malignancy index (RMI), risk of malignancy algorithm (ROMA). Methods: It was a cross sectional study conducted recruiting 88 women with adnexal masses who were planned for surgery. After baseline work up and ultrasound examination, serum samples were collected for estimation of CA 125 and HE4 levels. Serum HE4 levels were estimated using ELISA kit. RMI and ROMA score were calculated and diagnostic accuracy of HE4, CA 125, RMI, ROMA and their combination were compared. Cut off for HE4 and ROMA score were calculated using ROC curve. Results: Of 88 subjects, 66 were analyzed with 19 malignant (including 5 LMP) and 47 benign cases. The median value of HE4 among malignant cases was found to be significantly higher than among the benign cases. PPV and NPV of HE4 at a cut off 130.8 pMol/ml was 85.7% and 77.9% respectively. Highest PPV (88.9%) with acceptable NPV (80.7%) was found with ROMA followed by HE4 (PPV 85.7%; NPV 77.97%), RMI (PPV 76.92%; NPV 83%) and CA125 (PPV 52%; NPV 80.85%). Conclusion: HE4 levels were lower in Indian population both in malignant and benign tumours as compared to other studies. HE4 is a good discriminator and gives best accuracy when it is combined with CA125 in a logistic algorithm, ROMA.

Diseases caused by flaviviruses, including dengue fever and Japanese encephalitis, are major health problems in Vietnam. This cross-sectional study explored the feasibility of domestic dogs as sentinels to better understand risks of mosquito-borne diseases in Hanoi city. A total of 475 dogs serum samples from 221 households in six districts of Hanoi were analyzed by a competitive enzyme-linked immunosorbent assay (cELISA) for antibodies to the pr-E protein of West Nile virus and other flaviviruses due to cross-reactivity. The overall flavivirus seroprevalence in the dog population was 70.7% (95% CI = 66.4–74.8%). At the animal level, significant associations between seropositive dogs and district location, age, breed and keeping practice were determined. At the household level, the major risk factors were rural and peri-urban locations, presence of pigs, coil burning and households without mosquito-borne disease experience (p < 0.05). Mosquito control by using larvicides or electric traps could lower seropositivity, but other measures did not contribute to significant risk mitigation of flavivirus exposure in dogs. These results will support better control of mosquito-borne diseases in Hanoi, and they indicate that dogs can be used as sentinels for flavivirus exposure.

Background: Countries that have good rubella surveillance, report ∼10,000–20,000 rubella cases annually. In India, not many cases of rubella are reported. The Hebballi Agasi ward of Dharwad district in Karnataka state, India, reported rubella cases on the last week of January 2015. Objective: We investigated the outbreak by time, place, person, and clinical symptoms. Methods: We performed a cross-sectional study. We defined a case as any resident of Heballi Agasi who had fever and rash, with or without lymphadenopathy, arthralgia, conjunctivitis, coryza, and cough, after December 15, 2014. We collected sociodemographic details and clinical symptoms of patients. We collected 5 serum samples and sent them to the National Measles Laboratory, Bangalore. We tested for measles and rubella antibodies. We drew an epidemic curve and a spot map. We computed mean age of cases, and we calculated attack rates by mean age and gender. We calculated proportions to describe clinical symptoms, and we interviewed stakeholders regarding rubella vaccination. We continued surveillance until March 2015. Results: The population of Heballi Agasi was 1,458. We identified 15 rubella cases (9 girls and 6 boys). The outbreak lasted between December 10, 2014, and February 21, 2015, with a peak on January 16, 2015. The overall attack rate was 1% (15 of 1,458). The mean age of the cases was 6 years (range, 1–23). The attack rate was high (7.7%) among those aged 1–6 years (11 of 143). The attack rate among those aged >6 years was 0.3% (4 of 1,315). In addition to fever and rash, 93% of cases (14 of 15) had coryza, 47% had cough (7 of 15), and 40% had conjunctivitis (6 of 15). Lymphadenopathy was present in only 1 case (1 of 15), and arthralgia was absent among all 15 cases. There was no death among the cases. All 5 sera were positive for rubella and negative for measles. Rubella vaccination was not given for any of the cases because no rubella vaccination is provided in the routine immunization program. Conclusions: There was a rubella outbreak in Heballi Agasi ward. Children aged 1–6 years were most affected. We recommend rubella vaccination in the routine immunization.Funding: NoneDisclosures: None

We conducted a cross-sectional study among 194 pregnant women from two low-income settings in Cambodia. The inclusion period lasted from October 2015 through December 2017. Maternal serum samples were analyzed for persistent organic pollutants (POPs). The aim was to study potential effects on birth outcomes. We found low levels of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCP), except for heptachlors, β-hexachlorocyclohexane (HCH), heptachlor epoxide, and p,p’-DDE. There were few differences between the two study locations. However, the women from the poorest areas had significantly higher concentrations of p,p’-DDE (p < 0.001) and hexachlorobenzene (HCB) (p = 0.002). The maternal factors associated with exposure were parity, age, residential area, and educational level. Despite low maternal levels of polychlorinated biphenyls, we found significant negative associations between the PCB congeners 99 (95% CI: −2.51 to −0.07), 138 (95% CI: −1.28 to −0.32), and 153 (95% CI: −1.06 to −0.05) and gestational age. Further, there were significant negative associations between gestational age, birth length, and maternal levels of o,p’-DDE. Moreover, o,p’-DDD had positive associations with birth weight, and both p,p’-DDD and o,p’-DDE were positively associated with the baby’s ponderal index. The poorest population had higher exposure and less favorable outcomes.

SUMMARYSerum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1–95 years (January–October 2010) and analysed to assess the seroprevalence ofBordetella pertussis(BP) in Mexico. Subjects' gender, age, geographical region and socioeconomic status were extracted from the survey and compiled into a subset database. A total of 3344 subjects (median age 29 years, range 1–95 years) were included in the analysis. Overall, BP seroprevalence was 47·4%. BP seroprevalence was significantly higher in males (53·4%,P = 0·0007) and highest in children (59·3%) decreasing with advancing age (P = 0·0008). BP seroprevalence was not significantly different between regions (P = 0·1918) and between subjects of socioeconomic status (P = 0·0808). Women, adolescents and young adults were identified as potential sources of infection to infants. Booster vaccination for adolescents and primary contacts (including mothers) for newborns and infants may provide an important public health intervention to reduce the disease burden.

SummaryObjective: To evaluate the usefulness of IgA antiphospholipid antibodies as markers of thrombosis and/or antiphospholipid antibody syndrome. Patients and Methods: A cross-sectional study design in a tertiary, university-based, autoimmune reference hospital. Seven-hundred ninety-five patients classified into five different groups – autoimmune diseases (255), deep vein thrombosis (153), transitory ischemic attacks (108), obstetric complications (196), infectious diseases (83) and controls (81) – were tested for IgA, IgG and IgM aPL, and lupus anticoagulant. Plasma and serum samples were drawn for detection of aPL using an internationally standardized ELISA method and LA was carried out using coagulometric assays. Results: True IgA aPL were found only in two patients with systemic lupus erythematosus; these patients were also positive to IgG aPL. Conclusion: The incidence of true positivity to IgA anticardiolipin antibodies is extremely low. Their determination was not helpful in diagnosing the antiphospholipid syndrome or in explaining thrombotic events or aPL related manifestations – fetal loss – in the groups studied.
