Cognitive interviewing to improve women's empowerment questions in surveys: Application to the health and nutrition and intrahousehold relationships modules for the project‐level Women's Empowerment in Agriculture Index

In 2015, the United Nations adopted the Sustainable Development Goals, which include fostering gender equality and women's empowerment and ending hunger and malnutrition. To monitor progress and evaluate programmes that aim to achieve these goals, survey instruments are needed that can accurately assess related indicators. The project‐level Women's Empowerment in Agriculture Index (pro‐WEAI) is being developed to address the need for an instrument that is sensitive to changes in empowerment over the duration of an intervention. The pro‐WEAI includes new modules with previously untested survey questions, including a health and nutrition module (focused on women's agency in this area) and an intrahousehold relationships module. This study uses cognitive interviewing to identify how new survey questions might be misinterpreted and to understand what experiences women are referencing when they respond to these questions. This was undertaken with the goal of informing revision to the modules. The study was conducted in Bangladesh with women from nuclear, extended, and migrant‐sending households and from two regions of the country to identify difficulties with interpretation and response formulation across these groups. Findings revealed that questions were generally understood, but participants occasionally responded to the wrong part of the question, did not understand key phrases, or were uncomfortable with questions. The findings also suggested ways to revise the modules and strengthen the pro‐WEAI. The revised pro‐WEAI health and nutrition and intrahousehold relationships modules will advance the ability to measure changes in these domains and their relationship with the health and nutritional status of women and their children.     

European seroepidemiology network 2: Standardisation of assays for seroepidemiology of varicella zoster virus.

BACKGROUND: The aim of the European Sero-Epidemiology Network (ESEN2) is to harmonise the serological surveillance of vaccine-preventable diseases in Europe. OBJECTIVE: To allow comparison of antibody prevalence in different countries by standardising results into common units. STUDY DESIGN: For varicella zoster virus (VZV), a reference laboratory established a panel of 148 samples, characterised by indirect enzyme-immunoassay (ELISA), indirect immunofluorescence, and complement fixation test. Fifty-seven samples were also studied by the fluorescence antibody to membrane antigen test. The geometric mean of the antibody activity (GMAA) obtained from four ELISA determinations was used to characterise each sample of the panel as positive (GMAA: >100 mIU/ml), equivocal (GMAA: 50-100 mIU/ml) or negative (GMAA: <50 mIU/ml) for antibody to VZV (anti-VZV). Thirteen laboratories, using five different ELISA tests, tested the panel. RESULTS: Agreement with the reference laboratory was above 85% in all cases, and the R(2) values obtained from regression analysis of the quantitative results were always higher than 0.87. Finally, the regression equations could be used to convert national values into a common unitage. CONCLUSION: This study confirmed that results for anti-VZV obtained by different ELISA methods can be converted into common units, enabling the comparison of the seroprevalence profiles obtained in the participant countries.     

Effects of the gut-stimulating principle in Croton penduliflorus seed oil on the central nervous system

The gut-stimulating principle in Croton penduliflorus seed oil isolated as white crystals (CP crystals) significantly reduced pentobarbitone-induced sleeping time in mice at doses of 3 and 6 mg/kg intraperitoneally. Indomethacin (4 mg/kg) and atropine (0.044 mg/kg) significantly reversed the action of CP crystals on pentobarbitone sleeping time with indomethacin having a profound reversal effect. CP crystals significantly reduced the mean onset of convulsions and the mean death time in mice treated with a surely convulsive dose of strychnine. CP crystals significantly reduced the intensity of morphine and pethidine analgesia and prolonged the duration of pethidine analgesia. Most actions of CP crystals suggest that it stimulates the CNS and reduces the intensity of opioids (except codeine) while prolonging their duration of analgesic action.     

Association between eotaxin (CCL11), C-reactive protein, and antimicrobial antibodies in patients undergoing coronary angioplasty.

Eotaxin (CCL11) is a potent chemoattractant for eosinophils and lymphocytes. Apart from its functions in the eosinophilic system, eotaxin has been shown to be overexpressed in atherosclerosis. We therefore sought to determine whether chronic infection with Chlamydia pneumoniae or other infectious agents is correlated with concentrations of eotaxin or C-reactive protein since this mechanism could explain the finding that chronic infection stimulates smooth muscle cell migration and plaque development. Patients undergoing percutaneous coronary angioplasty (PCI) for acute coronary syndrome or stable angina were included in the study. Blood was drawn before PCI, at 6 weeks, and 6 and 12 months after coronary intervention. Eotaxin and C-reactive protein were determined by enzyme-linked immunosorbent assay (ELISA). Antibodies against Candida, C. pneumoniae, cytomegalovirus, Helicobacter pylori, and herpes simplex virus were measured by ELISA or immunofluorescence. Two hundred five consecutive patients undergoing PCI (stable angina, n = 136; acute coronary syndrome, n = 69) and 83 patients with normal coronary arteries were enrolled in the study. Eotaxin concentrations at inclusion were higher in patients with coronary artery disease than in control patients, p = .01, and comparable in patients with stable angina and those with acute coronary syndrome but did not correlate with C-reactive protein. Eotaxin concentrations at inclusion and during follow-up weakly correlated with concentrations of antibodies against C. pneumoniae, H. pylori, and herpes simplex virus but not with concentrations of antibodies against Candida or cytomegalovirus. Eotaxin concentrations and antibody titers against C. pneumoniae significantly increased following angioplasty and remained elevated thereafter. In conclusion, our data demonstrate that eotaxin concentrations are elevated independently from C-reactive protein in patients with coronary artery disease and correlate with antibodies against infectious agents known for chronic infection in humans.     

Immature teratoma of the tectum mesencephali with histopathological detection of rudimentary eye anlage in a 3‐year‐old boy: Report of a rare case

Intracranial teratoma is a rare neoplasm derived from omnipotent germinal cells that can contain mesoderm, endoderm and/or ectoderm layer tissue. Histologically teratomas are characterized by abnormal structures like teeth or bone that can be further subdivided into mature and immature according to the presence of incompletely differentiated tissue. Characteristic intracranial teratomas are space‐occupying lesions in the pineal region and often present with hydrocephalic symptoms due to aqueduct stenosis. A 3‐year‐old boy presented with a peracute hemiparesis, fatigue and speech deficit. MRI diagnostics showed a cystic, partially solid, inhomogeneous contrast‐enhancing formation at the top of the tectum mesencephali with consecutive aqueduct compression. The patient underwent a sub‐occipital craniotomy via a supracerebellar approach and complete resection was achieved. The histopathological examination mainly showed mature tissue of ectodermal, mesodermal and endodermal origin. However, small areas of undifferentiated neuroectodermal tissue within an optic vesicle formation were detected, leading to the diagnosis of an immature teratoma. In due course, the patient was discharged in good health without neurological deficits. To our knowledge, optic vesicle‐containing intracranial germ cell tumors are extremely rare. Here we report a unique case with immature neuroectodermal tissue within an optic vesicle formation in an otherwise mature teratoma.
