Being born in a hospital versus having a traditional birth attendant at home represents the most common early life policy change worldwide. By applying a difference-in-differences approach to register-based individual-level data on the total population, this paper explores the long-term economic effects of the opening of new maternity wards as an early life quasi-experiment. It first finds that th

In 1966, Gallai asked whether every connected graph has a vertex that is common to all longest paths. The answer to this question is negative. We prove that the answer is positive for outerplanar graphs and 2-trees. Another related question was raised by Zamfirescu in the 1980s: Do any three longest paths in a connected graph have a vertex in common? The answer to this question is unknown. We prov

Light pollution, light in the wrong place at the wrong time, is an emerging environmental issue with wide-ranging consequences. It interferes with the fundamental 24 h light–dark cycle, and has biological effects at all levels, from molecules to ecosystems, including human health and welfare. Here, exemplified by flood-lit churches, artificial lights compromise the survival of resident bats, as da

PurposeThe purpose of this study is to empirically identify and describe customer experience of unattended delivery services in e-grocery retail, and suggest propositions for further research and development of the research area.Design/methodology/approachThis exploratory research is based on a series of qualitative interviews to explore customer experience of unattended grocery delivery services.

Cassava is a vital food-security crop in Sub-Saharan Africa. Cassava crops are, however, severely affected by viral diseases transmitted by members of the whitefly species complex Bemisia tabaci. We have here investigated the role of olfaction in host selection behavior of the cassava whitefly B. tabaci SSA-ESA biotype. Surprisingly, we find that the whiteflies appear to make little use of olfacti

Radical excision of periorbital skin tumors is difficult without sacrificing excessive healthy tissue. Photoacoustic (PA) imaging is an emerging non-invasive biomedical imagi­­ng modality that has potential for intraoperative micrographic control of surgical margins. This is the first study to assess the feasibility of PA imaging for the detection of periocular skin cancer. Eleven patients underwe

The recent finding of the flea beetle species Podagrica fuscicornis (Linné, 1767) in a commercial market garden at Ystad just off the south coast of Skåne (Scania), the southernmost province of Sweden, is discussed. The species was found in August 2010 residing on plants of Lavatera cashmeriensis (Malvaceae), the follwing years in numbers. Old literature records from Sweden of the species (e.g. Gy

Objective: Abdominal aortic graft and endograft infection (AGI) is primarily treated by resection of the infected graft and restoration of distal perfusion through extra-anatomic bypass (EAB) or in situ reconstruction/repair (ISR). The aim of this study was to compare these surgical strategies in a nationwide multicentre retrospective cohort study. Methods: The Swedish Vascular Registry (Swedvasc)

Background: The drinking water in parts of Ronneby was heavily contaminated with perfluoroalkyl substances (PFAS) for decades. Although PFAS has endocrine-disrupting properties and may interfere with breastfeeding, the effects in populations with a point source of high exposure are unknown. Objectives: To investigate associations between high PFAS exposure and 1) initiation and 2) duration of brea

Spondyloarthritis (SpA) is an umbrella term describing a family of chronic inflammatory rheumatic diseases. These diseases are characterised by inflammation of the axial skeleton, peripheral joints, and entheseal insertion sites throughout the body which can lead to structural joint damage including formation of axial syndesmophytes and peripheral osteophytes. Genetic evidence, preclinical and cli

BACKGROUND: Current follow-up strategies for patients with renal cell carcinoma (RCC) after curative surgery rely mainly on risk models and the treatment delivered, regardless of the histological subtype. OBJECTIVE: To determine the impact of RCC histological subtype on recurrence and to examine the incidence, pattern, and timing of recurrences to improve follow-up recommendations. DESIGN, SETTING
