Dreaming on: dying behaviour and the romantic-individualist ethos

Abstract Over the last two decades and, most recently because of the COVID-19 pandemic, there has been a growing interest in studying topics related to dying and death in various fields of research. Research has started to explore, in more detail, death and bereavement among nonreligious people in contemporary Western societies. It is now well established that this large social group finds its own meaningful ways to come to terms with grief, loss and finitude. However, these studies typically do not include the perspectives of those living with life-threatening illness and facing death. Drawing on one and a half years of ethnographic research conducted among patients receiving palliative care in Switzerland, this study explores how a nonreligious orientation and other facets of human existence influence emotions and meaning making while dying. This is exemplified by the case of an atheist who I picked from the totality of fieldwork encounters in order to illuminate the nuances and complexities of living with terminal illness. The study found that secular and individualist values make it difficult to find closure and accept death. At the same time, the results show that the identification with the secular features of a worldview can increase well-being by ensuring a sense of permanence in actions and meaning-making habits in dying. Furthermore, this article makes the case for studying attitudes towards dying and death in relation to time and life situation

From growth to silence: expressive endeavours at the end of life

This ethnographic study explores how severely ill and dying per- sons participating in expressive forms of culture, such as art, blog- ging and talking, confront dying and death. Influenced by the increasing relevance of values such as expressivity and creativity and the mediatisation of everyday life, more and more people facing death in globalised Western culture seek their own expres- sive ways to deal with finitude in online and offline contexts. Framed by Tony Walter’s sociology of death, which captures key features of death attitudes within Western societies, this study identifies commonalities in the different expressive endeavours at the end of life. The data for the analysis stem from encounters with 12 persons receiving palliative care in Switzerland. The study found that the performances of individualistic expressivity are informed by the idea of personal growth, prosumer and sharing culture, a quest for belonging and the wish for silence. The findings aim to contribute to further the understanding of current forms of mediated dying in networked society

In-hospital Delay Increases the Risk of Perforation in Adults with Appendicitis

Background: The influence of in-hospital delay (time between admission and operation) on outcome after appendectomy is controversial. Methods: A total of 1,827 adult patients underwent open or laparoscopic appendectomy for suspected appendicitis in eleven Swiss hospitals between 2003 and 2006. Of these, 1,675 patients with confirmed appendicitis were included in the study. Groups were defined according in-hospital delay (≤12 vs. >12h). Results: Delay>12h was associated with a significantly higher frequency of perforated appendicitis (29.7 vs. 22.7%; P=0.010) whereas a delay of 6 or 9h was not. Size of institution, time of admission, and surgical technique (laparoscopic vs. open) were independent factors influencing in-hospital delay. Admission during regular hours was associated with higher age, higher frequency of co-morbidity, and higher perforation rate compared to admission after hours. The logistic regression identified four independent factors associated with an increased perforation rate: age (≤65years vs. >65years, odds ratio (OR) 4.5, P0 vs. Charlson index=0, OR 2.3, P12 vs. ≤12h, OR 1.5, P=0.005). Perforation was associated with an increased reintervention rate (13.4 vs. 1.6%; P<0.001) and longer length of hospital stay (9.5 vs. 4.4days; P<0.001). Conclusions: In-hospital delay negatively influences outcome after appendectomy. In-hospital delay of more than 12h, age over 65years, time of admission during regular hours, and the presence of co-morbidity are all independent risk factors for perforation. Perforation was associated with a higher reintervention rate and increased length of hospital sta

Influence of thoracic epidural analgesia on postoperative pain relief and ileus after laparoscopic colorectal resection: Benefit with epidural analgesia

Background: Thoracic epidural analgesia (TEA) provides superior analgesia with a lower incidence of postoperative ileus when compared with systemic opiate analgesia in open colorectal surgery. However, in laparoscopic colorectal surgery the role of TEA is not well defined. This prospective observational study investigates the influence of TEA in laparoscopic colorectal resections. Methods: All patients undergoing colorectal resection between November 2004 and February 2007 were assessed for inclusion into a prospective randomized trial investigating the influence of bisacodyl on postoperative ileus. All patients treated by laparoscopic resection from this collective were eligible for the present study. Primary endpoints were use of analgesics and visual analogue scale (VAS) pain scores. Secondary endpoint concerned full gastrointestinal recovery, defined as the mean time to the occurrence of the following three events (GI-3): first flatus passed, first defecation, and first solid food tolerated. Results: 75 patients underwent laparoscopic colorectal resection, 39 in the TEA group and 36 in the non-TEA group. Patients with TEA required significantly less analgesics (metamizol median 3.0g [0-32g] versus 13.8g [0-28g] (p<0.001); opioids mean 12mg [±2.8mg standard error of mean, SEM] versus 103mg [±18.2mg SEM] (p<0.001). VAS scores were significantly lower in the TEA group (overall mean 1.67 [± 0.2 SEM] versus 2.58 [±0.2 SEM]; p=0.004). Mean time to gastrointestinal recovery (GI-3) was significantly shorter (2.96 [±0.2 SEM] days versus 3.81 [±0.3 SEM] days; p=0.025). Analysis of the subgroup of patients with laparoscopically completed resections showed corresponding results. Conclusion: TEA provides a significant benefit in terms of less analgesic consumption, better postoperative pain relief, and faster recovery of gastrointestinal function in patients undergoing laparoscopic colorectal resectio

Use of severity classification systems in the surgical decision-making process in emergency laparotomy for perforated diverticulitis

Purpose: Hartman's procedure (HP) or primary anastomosis (PA) are the two surgical techniques used in patients undergoing emergency colectomy for perforated diverticulitis. There are no objective criteria to guide the surgeon's choice of procedure. This study assesses whether classification and scoring systems can be used in the decision-making process. Methods: One hundred eleven patients undergoing emergency laparotomy for perforated diverticulitis were analyzed. Logistic regression and interaction models were used to determine the predictive value in the two settings. Results: Sixty five patients underwent HP and 46 patients underwent PA. Patients with HP had significantly higher scores, median age, and were more often on immunosuppressive medication. Mortality and surgical morbidity did not differ between the groups. The clinical anastomotic leak rate was 28.3% in the PA group. In the univariate logistic regression for in-hospital death, all scores showed a significant influence. The multivariate logistic regression analysis showed that only Charlson comorbidity index (CCI) and American Society of Anesthesiologists score had a significant influence on mortality. Each score was analyzed for its predictive value regarding mortality and morbidity with respect to type of operative procedure. Only CCI revealed a trend towards statistical significance. The risk of death increases with increasing CCI when PA is performed compared to HP. Conclusion: None of the tested scores can be used to help the surgeon decide whether a PA or HP is appropriate in a specific patient. Comorbidity, represented as CCI in this study, might be more important than the locoregional situatio

Relating hygroscopicity and composition of organic aerosol particulate matter

A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the chemical and photochemical oxidation of several organic precursors in a smog chamber. Electron ionization mass spectra of the non-refractory submicron aerosol were simultaneously determined with an aerosol mass spectrometer (AMS), and correlations between the two different signals were investigated. SOA hygroscopicity was found to strongly correlate with the relative abundance of the ion signal m/z 44 expressed as a fraction of total organic signal (f44). m/z 44 is due mostly to the ion fragment CO2+ for all types of SOA systems studied, and has been previously shown to strongly correlate with organic O/C for ambient and chamber OA. The analysis was also performed on ambient OA from two field experiments at the remote site Jungfraujoch, and the megacity Mexico City, where similar results were found. A simple empirical linear relation between the hygroscopicity of OA at subsaturated RH, as given by the hygroscopic growth factor (GF) or "κorg" parameter, and f44 was determined and is given by κorg=2.2×f44−0.13. This approximation can be further verified and refined as the database for AMS and HTDMA measurements is constantly being expanded around the world. The use of this approximation could introduce an important simplification in the parameterization of hygroscopicity of OA in atmospheric models, since f44 is correlated with the photochemical age of an air mass

PGC-1β modulates statin-associated myotoxicity in mice

Statins inhibit cholesterol biosynthesis and lower serum LDL-cholesterol levels. Statins are generally well tolerated, but can be associated with potentially life-threatening myopathy of unknown mechanism. We have shown previously that statins impair PGC-1β expression in human and rat skeletal muscle, suggesting that PGC-1β may play a role in statininduced myopathy. PGC-1β is a transcriptional co-regulator controlling the expression of important genes in mitochondrial biogenesis, antioxidative capacity and energy metabolism. The principle aim of the current study was to investigate the interaction between atorvastatin and PGC-1β in more detail. We therefore treated wild-type mice and mice with selective skeletal muscle knockout of PGC-1β (PGC-1β(i)skm−/− mice) with oral atorvastatin (5 mg/kg/day) for 2 weeks. At the end of treatment, we determined body parameters, muscle function, structure, and composition as well as the function of muscle mitochondria, mitochondrial biogenesis and activation of apoptotic pathways. In wild-type mice, atorvastatin selectively impaired mitochondrial function in glycolytic muscle and caused a conversion of oxidative type IIA to glycolytic type IIB myofibers. Conversely, in oxidative muscle of wild-type mice, atorvastatin enhanced mitochondrial function via activation of mitochondrial biogenesis pathways and decreased apoptosis. In PGC-1β(i)skm−/− mice, atorvastatin induced a switch towards glycolytic fibers, caused mitochondrial dysfunction, increased mitochondrial ROS production, impaired mitochondrial proliferation and induced apoptosis in both glycolytic and oxidative skeletal muscle. Our work reveals that atorvastatin mainly affects glycolytic muscle in wild-type mice and demonstrates the importance of PGC-1β for oxidative muscle integrity during long-term exposure to a myotoxic agent.Peer reviewe

Intercomparison Study of Six HTDMAs: Results and Recommendations

We report on an intercomparison of six different hygroscopicity tandem differential mobility analysers (HTDMAs). These HTDMAs are used worldwide in laboratory experiments and field campaigns to measure the water uptake of aerosol particles and have never been intercompared. After an investigation of the different design of the instruments with their advantages and inconveniencies, the methods for calibration, validation and data analysis are presented. Measurements of nebulised ammonium sulphate as well as of secondary organic aerosol generated from a smog chamber were performed. Agreement and discrepancies between the instruments and to the theory are discussed, and final recommendations for a standard instrument are given, as a benchmark for laboratory or field experiments to ensure a high quality of HTDMA data.JRC.H.2-Climate chang
