Pain and psychological health status in chronic pain patients with migration background—the Zurich study

The objective of this paper is to investigate whether there were differences in pain and psychological health status in chronic pain patients with and without migration background before and after an 8-week interdisciplinary outpatient pain programme (IOPP). One hundred eighteen consecutively assessed patients were included. Pain and psychological health were recorded prior to and after the intervention, and at the 3-, 6- and 12-month follow-up. The migrant group experienced a statistically significant and clinically relevant higher amount of pain and worse psychological functioning than the non-migrant group at all time points. Statistically significant differences between the groups for the variables depression, anxiety, kinesiophobia and passive coping, in particular catastrophizing, were observed in the short and long term. The non-migrant group improved continuously on all outcome measurements at all time points. The results show differences in outcome for chronic pain patients with and without migration background. High pain intensity, high levels of depression, anxiety and catastrophizing at baseline appear to be major barriers for improvement in a sample of migrant patients when participating in an IOPP. Treatments may have to be tailored to the specific needs of this patient group to better address their poor psychological health status and to improve the course of the pain disorde

A gridded hourly precipitation dataset for Switzerland using rain-gauge analysis and radar-based disaggregation

Rain gauges and weather radars both constitute important devices for operational precipitation monitoring. Gauges provide accurate yet spotty precipitation estimates, while radars offer high temporal and spatial resolution yet at a limited absolute accuracy. We propose a simple methodology to combine radar and daily rain-gauge data to build up a precipitation dataset with hourly resolution covering a climatological time period. The methodology starts from a daily precipitation analysis, derived from a dense rain-gauge network. A sequence of hourly radar analyses is then used to disaggregate the daily analyses. The disaggregation is applied such as to retain the daily precipitation totals of the rain-gauge analysis, in order to reduce the impact of quantitative radar biases. Hence, only the radar's advantage in terms of temporal resolution is exploited. In this article the disaggregation method is applied to derive a 15-year gridded precipitation dataset at hourly resolution for Switzerland at a spatial resolution of 2 km. Validation of this dataset indicates that errors in hourly intensity and frequency are lower than 25% on average over the Swiss Plateau. In Alpine valleys, however, errors are typically larger due to shielding effects of the radar and the corresponding underestimation of precipitation periods by the disaggregation. For the flatland areas of the Swiss Plateau, the new dataset offers an interesting quantitative description of high-frequency precipitation variations suitable for climatological analyses of heavy events, the evaluation of numerical weather forecasting models and the calibration/operation of hydrological runoff models
