Abstract

In recent years, strange phenomena occurred in the Caribbean, Gulf of Mexico and West Africa: a massive tide of sargassum, brown algae, washed ashore causing considerable damage to the local economy and environment. The sargassum mostly consists of Sargassum Natans and Sargassum Fluitans. Old studies concluded that the sargassum came from the Sargasso Sea, however the most recent massive tide of sargassum (named as golden tide) came from an area north of the Amazon river delta. Texas A&M University of Galveston and the University of Florida developed detection systems in cooperation with NASAs satellite images. With the detection system it is possible to track, trace and make forecasts of sargassum landings. Hereby it is possible to act a few days before the sargassum washes ashore, instead of reacting when it landed on the beach already. Most of the problems occur when the massive influxes of sargassum are washed ashore. Currently, the most used harvesting methods on the beach are by use of rakes and wheelbarrows or by using mechanical equipment like a cane loaders and front-end loaders. The beach cleaning methods causes beach erosion and endangers local wildlife. Therefore, harvesting methods at sea are under development. Sargassum is an organic material and can be an useful source for processing. The most used processing methods of sargassum are burying at the beach or using it as a fertiliser. One of the challenges in processing sargassum is working with the unpredictable appearing character of sargassum. The known detection methods have been critically analysed and the most favourable method is developed by Texas A&M University Galveston. This system is applicable on other areas as well and it makes forecasts of sargassum landings. The harvesting methods have also been critically analysed and it can be concluded that the most recommended harvesting method has to be done at sea in combination with a floating barrier. Most of the problems are avoided in this mann, Civil Engineering and Geosciences, Multidisciplinary project

Abstract

Hoofddoel van het pilotprogramma is waterbeheerders, terreinbeherende instanties en provincies te ondersteunen in hun activiteiten een koppeling tot stand te brengen tussen waterberging en - buffering en natuurbehoud en -ontwikkeling. Eén van de geselecteerde pilots uit het pilotprogramma ligt langs de Beerze. De Beerze is representatief voor de huidige situatie in veel Brabantse beekdalen: er is sprake van een waterkwantiteitsprobleem, en (tijdelijke) berging van het beekwater in natuurgebieden stuit op problemen, vooral vanwege de (eutrofe) waterkwaliteit. Tegelijkertijd speelt verdroging van natuurgebieden een rol. De pilot Beerze ligt in het traject Logtse Baan - Logtse Velden - Smalbroeken. De onderzoeksperiode van deze pilot besloeg 2004 tot medio 2007

Abstract

Chronotype may affect tolerance for circadian disruption induced by shift work. This study examines the association between chronotype, self-reported sleep timing, shift type preference, and sleep problems among nurses, and studies chronotype stability over time. The study included 37,731 Dutch female nurses who completed a baseline (2011) and follow-up questionnaire (2017), with information on shift work (e.g., job history, shift type preference [collected in 2017 only]), and sleep characteristics (e.g., chronotype, preferred sleep-wake time in a work-free period [collected in 2017 only], and sleep problems between working days according to Medical Outcomes Study-Sleep Problem Index II [MOS-SPI-II]). The association between chronotype and sleep timing was examined using (age-adjusted) linear regression. Associations between chronotype and shift type preference and sleep problems (MOS-SPI-II >30) were examined using ordered logistic and Poisson regression, respectively. With later chronotype, midsleep time increased (definite evening vs. intermediate types [reference]: β = 55 min, 95% confidence interval [95% CI]: 54-55), the odds ratio (OR) for 1-point increase in preference for night (2.68; 95% CI: 2.48-2.90) and evening shifts increased (OR 2.20; 95% CI: 2.03-2.38), while the odds for day (OR 0.17; 95% CI: 0.16-0.18) and morning shifts (OR 0.22; 95% CI: 0.21-0.24) decreased. Intermediate chronotype was associated with fewer sleep problems (median MOS-SPI-II = 27.2, p < 0.01), compared with definite morning (28.9) and evening types (31.7). This study shows that chronotype is associated with sleep-wake times in a work-free period, shift type preference, and sleep problems in nurses. Future studies on the association of shift work-induced circadian disruption and health outcomes should therefore consider chronotype as effect-modifier., (© 2024 The Author(s).

Abstract

Background: Uncertainty concerning anesthetic procedures and risks in children requiring anesthesia may cause concerns in parents and caregivers., Aims: To explore parental expectations and experiences regarding their child's anesthesia using questionnaires designed with parental input., Methods: This observational cross-sectional cohort study included parents (including caregivers) of children undergoing anesthesia in a tertiary pediatric referral university hospital. The study consisted of two phases. In Phase 1, we developed three questionnaires with parental involvement through a focus group discussion and individual interviews. The questionnaires focused on parental satisfaction, knowledge, concerns, and need for preparation regarding their child's anesthesia. In Phase 2, independent samples of parents completed the questionnaires at three time points: before the preanesthesia assessment (T1), 2 days after the preanesthesia assessment (T2), and 4 days after the anesthetic procedure (T3)., Results: In Phase 1, 22 parents were involved in the development of the questionnaires. The three questionnaires contained 43 questions in total, of which 10 had been proposed by parents. In Phase 2, 78% (474 out of 934) parents participated at T1, 36% (610 out of 1705), at T2 and 34% (546 out of 1622) at T3. Parental satisfaction scores were rated on a visual analogue scale for the preanesthesia assessment with a median of 87/100, and with a median of 90/100 for the anesthetic procedure (0: not satisfied and 100: satisfied). Parental concerns were rated with a median of 50/100 (0: no concerns and 100: extremely concerned). Parental answers from the questionnaire at T2 revealed significant knowledge deficits, with only 73% reporting that the anesthesiologist was a physician. Parents preferred to receive more information about the procedure, especially regarding the intended effects and side effects of anesthesia., Conclusions: Overall, parental satisfaction scores regarding the pediatric anesthesiology procedure were high, with a minority expressing concerns. Parents indicated a preference for their child's anesthesiologist to visit them both before and after the anesthetic procedure. Parental expectations regarding anesthesia did not completely correspond with the information provided; more information from the clinician about the intended effects and side effects of anesthesia was desired., (© 2023 The Authors.

Abstract

Chronotype is frequently assessed in human observational studies using various morningness-eveningness questionnaires. An alternative single-item chronotype question has been proposed for its reduced administration time and its accessibility to all types of populations. We investigated whether this single-item chronotype is associated with dim light melatonin onset, the "gold standard" for estimating the endogenous circadian phase. We used data from a randomised trial in 166 (non-)Hodgkin lymphoma survivors with cancer-related fatigue. All participants completed a questionnaire, including a single-item chronotype question. A subsample of 47 participants also provided saliva samples before sleep onset for melatonin measurement. Using multiple linear regression, we examined whether chronotype based on a single question was associated with dim light melatonin onset. The subsample of 47 participants had a mean age of 44.6 years. The mean (SD) dim light melatonin onset was at 8:42 (1:19) p.m. and the most common chronotype was more evening than morning person (29.2%). A gradual increase in dim light melatonin onset with later chronotype (i.e. evening preference) was observed, with a mean ranging from 7:45 p.m. in definite morning persons to 9:16 p.m. in definite evening persons. Our study shows that single-item chronotype is associated with dim light melatonin onset as a marker of the endogenous circadian phase of fatigued lymphoma survivors. This type of chronotype assessment can therefore be a useful alternative for more extensive morningness-eveningness questionnaires., (© 2022 European Sleep Research Society.)

Abstract

Aim: The aim of this systematic review is to give an overview of the literature on treatment options for posttraumatic stress disorder (PTSD) following childbirth and to assess their efficacy. Method: PubMed, Embase, Web of Science, Cochrane and PsycINFO were searched using "PTSD", "childbirth" and "therapy" as terms for studies in English language published between 2000 and 2017. Additional studies were identified by checking reference lists. Studies were included when presence of PTSD was confirmed prior to treatment and childbirth was the traumatic event focused on. All studies were reviewed on sample size, study design, used instruments, sample characteristics, type of treatment and the result of treatment regarding PTSD (symptoms). Results: Six studies met the inclusion criteria. One study on debriefing, three studies on cognitive behavioral therapy (CBT) and two studies on eye movement desensitization and reprocessing (EMDR) were identified. Both EMDR and CBT appear to be promising therapies for PTSD following childbirth. Debriefing seems to be beneficial when women request it themselves. Conclusions: EMDR and CBT seem to be effective as therapy for PTSD following childbirth. However, evidence is still limited and more controlled trials are needed to draw conclusive results.

Abstract

In this contribution two methods from the domain of information retrieval are compared. The goal of the retrieval is to select from a library of pathology reports those ones that are most similar to a given report. The SNOMED codes that accompany these reports are presented to the pathologist who has to code the given report with the aim to improve the quality of coding. The reports were represented either as a vector of words or as a vector of N-grams. Both 4-, 5- and 6-grams were used. The similarity of the reports was determined by comparing the SNOMED terms that were added to the reports. It could be concluded that the word-based method was consistently better than the N-gram method.

Abstract

This paper presents a method of automatic classification of clinical narrative through text comparison. A diagnosis report can be classified by searching archive texts that show a high textual similarity, and the 'nearest neighbor classifies the case. This paper describes the method's theoretical background and gives implementation details. Large scale simulation experiments were run with a wide range of histology reports. Results showed that for 80-84% of the trials, relevant classification lines were included among the first five alternatives. In 5% of the cases, retrieval was unsuccessful due to the absence of relevant archive reports. From the results it is concluded that the method is a versatile approach for finding potentially good classifications.

Abstract

Automatic speech recognition has since long been seen as an ideal method for innovation in diagnosis reporting. Speech technology now seems on the verge of introducing (commercially) attractive systems. The selection of a good speech recogniser is only one consideration in system design. Interface aspects, error handling, reporting method and implementation in the daily working routine are interwoven with the selection of an appropriate speech recognition technique, and should therefore be determined first.
