    Labelled loans and human capital investments

    Liquidity constraints are known to significantly impede human capital investment decisions in developing countries. However, it is not obvious whether, and the extent to which, labelled microcredit - linked with the investment by name only - will boost human capital investments, particularly since money is fungible and a label is not a strong commitment. Drawing on a cluster randomised controlled trial of a sanitation microloan intervention in rural India, we show that labelled microcredit is effective in increasing sanitation investments. However, not all loans are used for sanitation investments. Testing predictions from a theoretical model that integrates loan labels provides novel evidence that loan labels influence household borrowing and investment decisions. Labelling of loans - which to date has not received much attention in the literature - is a viable strategy to improve uptake of lumpy preventive health investments

    Imperfect capital markets and commitment problems impede lumpy human capital investments. Labeled loans have been postulated as a potential solution to both constraints, but little is known about the role of the label in influencing investment choices in practice. We draw on a cluster randomized controlled trial in rural India to test predictions from a theoretical model, providing novel evidence that labeled microcredit is effective in influencing household borrowing and investment decisions and increasing take-up of a lumpy human capital investment, a toilet

    The analysis of paired cerebrospinal fluid (CSF) and serum samples with isolectric focusing (IEF) can yield different patterns which can be of aid in the differential diagnosis of central nervous system (CNS) disorders. Rarely, a single CSF-restricted IgG band, which is not included within these patterns, can be detected in association with inflammatory disorders, multiple sclerosis (MS) above all. However, the diagnostic meaning of this abnormality is still uncertain. The main aim of our multicenter study was to establish the frequency and disease associations of single CSF IgG bands. Differences in the CSF profiles between MS and other diseases, and the follow-up patterns were also evaluated. Medical records of patients who underwent CSF analysis, which included IEF, over a 11.5-year period were retrospectively scrutinized at the participating centers, which used similar IEF techniques. One hundred and fifty-one of 9422 CSF reports (1.6%) showed single CSF-restricted IgG bands. Of the 129 patients with a definite diagnosis, 58.2% had CNS inflammatory-demyelinating diseases (the most frequent being MS: 21.7%), 6.2% tumours, 5.4% inflammatory peripheral nervous system diseases and 30.2% miscellaneous diseases. At follow-up, 3 out of the 10 patients with a repeated CSF analysis had developed an oligoclonal band pattern. Our findings indicate that single CSF IgG bands tend to associate with diseases characterized by the involvement of intrathecal humoral immune responses, and strongly support the notion that this abnormality should be regularly reported, thus alerting clinicians of possible inflammatory disorders of the CNS

    Intronic FGF14 GAA repeat expansions are a common cause of ataxia syndromes with neuropathy and bilateral vestibulopathy

    BACKGROUND: Intronic GAA repeat expansions in the fibroblast growth factor 14 gene (FGF14) have recently been identified as a common cause of ataxia with potential phenotypic overlap with RFC1-related cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS). Our objective was to report on the frequency of intronic FGF14 GAA repeat expansions in patients with an unexplained CANVAS-like phenotype. METHODS: We recruited 45 patients negative for biallelic RFC1 repeat expansions with a combination of cerebellar ataxia plus peripheral neuropathy and/or bilateral vestibulopathy (BVP), and genotyped the FGF14 repeat locus. Phenotypic features of GAA-FGF14-positive versus GAA-FGF14-negative patients were compared. RESULTS: Frequency of FGF14 GAA repeat expansions was 38% (17/45) in the entire cohort, 38% (5/13) in the subgroup with cerebellar ataxia plus polyneuropathy, 43% (9/21) in the subgroup with cerebellar ataxia plus BVP and 27% (3/11) in patients with all three features. BVP was observed in 75% (12/16) of GAA-FGF14-positive patients. Polyneuropathy was at most mild and of mixed sensorimotor type in six of eight GAA-FGF14-positive patients. Family history of ataxia (59% vs 15%; p=0.007) was significantly more frequent and permanent cerebellar dysarthria (12% vs 54%; p=0.009) significantly less frequent in GAA-FGF14-positive than in GAA-FGF14-negative patients. Age at onset was inversely correlated to the size of the repeat expansion (Pearson's r, -0.67; R2=0.45; p=0.0031). CONCLUSIONS: GAA-FGF14-related disease is a common cause of cerebellar ataxia with polyneuropathy and/or BVP, and should be included in the differential diagnosis of RFC1 CANVAS and disease spectrum

    Broadband Multi-wavelength Properties of M87 during the 2017 Event Horizon Telescope Campaign

    Abstract: In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring morphology and size are consistent with theoretical expectations for a weakly accreting supermassive black hole of mass ∼6.5 × 109 M ⊙. The EHTC also partnered with several international facilities in space and on the ground, to arrange an extensive, quasi-simultaneous multi-wavelength campaign. This Letter presents the results and analysis of this campaign, as well as the multi-wavelength data as a legacy data repository. We captured M87 in a historically low state, and the core flux dominates over HST-1 at high energies, making it possible to combine core flux constraints with the more spatially precise very long baseline interferometry data. We present the most complete simultaneous multi-wavelength spectrum of the active nucleus to date, and discuss the complexity and caveats of combining data from different spatial scales into one broadband spectrum. We apply two heuristic, isotropic leptonic single-zone models to provide insight into the basic source properties, but conclude that a structured jet is necessary to explain M87’s spectrum. We can exclude that the simultaneous γ-ray emission is produced via inverse Compton emission in the same region producing the EHT mm-band emission, and further conclude that the γ-rays can only be produced in the inner jets (inward of HST-1) if there are strongly particle-dominated regions. Direct synchrotron emission from accelerated protons and secondaries cannot yet be excluded

    I won't let you "behind". The impact of migration on sending households

    Get PDF
    A boost in the scale and complexity of international migration flows have occurred in the last decades. Movements of large numbers of people may produce welfare gains to families and communities left behind. This thesis analyses the implications of migration on well-being of sending societies, adopting a household-level perspective and addressing two specific issues: the impact of remittances on health consumption decisions of relatives left behind, and the role of migration as risk management strategy in response to natural shock exposure. The effect of international remittances on household healthcare consumption is tested using data from the “Peruvian National Survey of Households”. Remittances positively impact on healthcare consumption shares and this propensity is independent of the occurrence of a health shock, confirming the importance of migrant transfers for human capital accumulation. In the second part, I identify whether and under which circumstances migration represents a coping strategy to deal with sudden onset climatic shocks, examining the case of Hurricane Mitch in Nicaragua. The findings obtained show that shock severity does not act as push factor for international migration as a whole. Only individuals belonging to agricultural households experiencing high exposure to the natural disaster increase their later likelihood to move abroad. Remittances turn out to be an efficient insurance tool to recover after natural shocks. Income flows from international migrants support household welfare preservation over the two years following the disaster, reducing the risk of being trapped into poverty

    Objectives: The aim of this study was to evaluate the efficacy and safety of lispro insulin for the treatment of feline diabetic ketoacidosis (DKA). Times to resolution of hyperglycaemia, ketosis and acidosis were compared between cats treated with continuous rate infusion (CRI) of lispro insulin and cats treated with CRI of regular insulin. Methods: Client-owned cats with naturally occurring DKA, newly diagnosed with diabetes mellitus (DM) or already receiving treatment for DM, were included. Diagnosis of DKA involved the presence of at least two clinical signs consistent with DKA (eg, polyuria/polydipsia, anorexia, severe lethargy, vomiting and dehydration), blood glucose (BG) concentration >13.9 mmol/l (>250 mg/dl), blood beta hydroxybutyrate (BHB) concentration >2.5 mmol/l and venous pH <7.3 or bicarbonate <15 mEq/l. Cats were treated with a standard protocol of an intravenous (IV) CRI of regular insulin (group R) or lispro insulin (group L). The time to resolution of DKA was defined as the time interval from when the IV CRI of insulin began until marked hyperglycaemia (BG >13.9 mmol/l [>250 mg/dl]), ketosis (BHB concentration >1 mmol/l) and acidosis (venous pH <7.3 and/or bicarbonate <15 mEq/l) resolved. Results: Eighteen DKA cases (nine per group) were enrolled into the study. There were no significant differences in the median time to resolution of three variables (hyperglycaemia, ketosis and acidosis) between the two groups. Two cats in group R developed hypoglycaemia during the CRI of insulin. One cat in group L and three cats in group R developed hypophosphataemia, which required phosphate supplementation. Conclusions and relevance: IV CRI of lispro insulin has few side effects and appears to be as effective as IV CRI of regular insulin in the treatment of cats with DKA
