CONTEXT Chronic low back pain (LBP) has been reported with a high incidence in elite rowers. It results in less effective training, long interruptions in training, and a drop in performance. OBJECTIVE The authors hypothesized that exercise-induced LBP in rowers is caused by a chronic functional compartment syndrome (CFCS) of the multifidus muscle. DESIGN Controlled clinical trial. SETTING...
Abstract Background Centralization of pancreatic surgery in the Netherlands has been ongoing since 2011. The aim this study was to assess how centralization affected likelihood resection and survival patients with non-metastatic head periampullary cancer, diagnosed hospitals without services. Methods An observational cohort performed on nationwide data from Cancer Registry (2009–2017), includin...
This paper describes a methodology, based on dynamical systems theory, to model and predict streamflow at the daily scale. The model is constructed by developing a multidimensional phase-space map from observed streamflow signals. Predictions are made by examining trajectories on the reconstructed phase space. Prediction accuracy is used as a diagnostic tool to characterize the nature, which ra...
A homologue series of aliphatic streptomycylamines (SM-amines) have been prepared and tested in vitro (binding to 70S ribosomes) and in vivo (MIC). The short-chain SM-amines act as streptomycin (SM) but are less active than SM. They are inactive towards a SM-resistant Escherichia coli, our strain 042. The long-chain SM-amines are active both towards our sensitive and resistant E. coli, our s...
We cast the Reissner Nordstrom solution in a particular co-ordinate system which shows dynamical evolution from initial data. The initial data for the E < M case is regular. This procedure enables us to treat the metric as a collapse to a singularity. It also implies that one may assume Wald axioms to be valid globally in the Cauchy development, especially when Hadamard states are chosen. We ca...
Background: While a number of countries have reported rising preterm birth rates over the past two decades, none has examined the effects of socioeconomic status on preterm birth at a national level. Aim: To document the changing incidence of preterm birth in New Zealand over the past 20 years and to determine whether particular socioeconomic or ethnic subsections of the population have contrib...
BACKGROUND Plasmodium falciparum gametocytes are essential for malaria transmission. Malaria control measures that aim at reducing transmission require an accurate characterization of the human infectious reservoir. METHODS We longitudinally determined human infectiousness to mosquitoes and P. falciparum carriage by an ultrasensitive RNA-based diagnostics in 130 randomly selected inhabitants ...
