Objective: To study how the choice of the first assisted reproductive technology treatment type affects the cumulative live birth rate (CLBR) in couples with high sperm DNA fragmentation index (DFI). Design: Longitudinal cohort study. Setting: University-affiliated fertility clinic. Patient(s): A total of 2,713 infertile couples who underwent assisted reproductive technology treatment between 2007

Background: Doppler ultrasound can diagnose testicular torsion with high sensitivity and specificity but may delay surgical treatment. This study aims to assess whether the use of doppler ultrasound, in cases with intermediate clinical suspicion of testicular torsion, can improve diagnostic accuracy compared to clinical assessment alone. Methods: We implemented a new clinical algorithm where patie

The analysis of surface wave dispersion curves is a way to infer the vertical distribution of shear wave velocity. The range of applicability is extremely wide: going, for example, from seismological studies to geotechnical characterizations and exploration geophysics. However, the inversion of the dispersion curves is severely ill-posed and only limited efforts have been put in the development of

The Whitham equation is a nonlocal shallow water-wave model which combines the quadratic nonlinearity of the KdV equation with the linear dispersion of the full water wave problem. Whitham conjectured the existence of a highest, cusped, traveling-wave solution, and his conjecture was recently verified in the periodic case by Ehrnström and Wahlén. In the present paper we prove it for solitary waves

Juice-pressing residues, among them blackcurrant pomace, are valuable materials for being upgraded in food products. Their excellent nutritional profiles in line with their functional properties allow a wide range of applications. The current study was performed to evaluate the overall liking of a pomace-enriched thin crispy-baked bread product in five European countries, and to obtain suggestions

This article explores how emotions connected to the Government’s handling of the Covid-19 outbreak in Sweden relates to behaviors to stop the spread of the virus, and which emotions functions as mediators in this relationship. The Swedish approach to handling the outbreak greatly differed from how many other Western European countries handled the situation and thus makes an important case to study

In retrospect and erroneously the nineteenth century international gold standard was interpreted as a quest for monetary discipline. The discipline argument was introduced after WWI in support for a restoration of the gold standard. The interwar failure led to an emphasis on international balances, the argument which came to the fore in the preparations for the Bretton Woods system. The balance ar

This paper analyzes land-system dynamics changes due to energy infrastructure development and explores the environmental and social ramifications of hydraulic fracturing, through a case study in Central Appalachia. Grounded in photographic data, satellite images, and ethnographic material, this study demonstrates landscape and embodied experiences of change over time. Data show major shifts in ter

This essay examines the common empirical connection between trust in people in general (social trust) and trust in the courts and the police (so-called legal trust). In much of the world there is a strong correlation between social trust and legal trust, which is sometimes interpreted as a causal connection from legal trust to social trust. But in many African countries, the correlation breaks dow

Background: Oropharyngeal cancer (OPC) is an important cause of cancer-related mortality. Early detection of OPC results in a favorable prognosis and higher survival rates. Infection by high-risk types of human papillomavirus (HPV) is a risk factor for OPC with an upward trend globally. Medical students' knowledge and awareness of HPV-related OPC can be crucial in the preventive efforts. Aim: To a

Genom analys av hennes större mjölkkindtand (dp4-) har hennes härkomst och mobilitet synliggjorts. Totalt genomfördes 20 ablationer på flickans tand. Ablationerna gjordes med ett mellanrum på ca 140 μm och följer tandbildningen, där den första ablationen gjordes närmst kronan (som bildas först) och den sista ablationen närmst roten (som bildas sist), vilket motsvarar en ungefärlig ålder på en dryg

The corona pandemic has put intergenerational relationships in focus in ways previously never experiences. In many national contexts, lockdowns and restrictions have caused forced generational separation in families. In Sweden, the official government standpoint of generational separation – all citizens over 70 were to avoid contact with others, and especially to stay away from interactions with g
