Evolution of anaesthesia care and related events between 1996 and 2010 in Switzerland.

BACKGROUND: Anaesthesia Databank Switzerland (ADS) is a voluntary data registry introduced in 1996. Its ultimate goal is to promote quality in anaesthesiology. METHODS: The ADS registry analyses routinely recorded adverse events and provides benchmark comparisons between anaesthesia departments. Data collection comprises a set of 31 variables organised into three modules, one mandatory and two optional. RESULTS: In 2010, the database included 2,158,735 anaesthetic procedures. Over time, the proportions of older patients have increased, the largest group being aged 50-64 years. The percentage of patients with American Society of Anesthesiologists (ASA) status 1 has decreased while the percentage of ASA status 2 or 3 patients has increased. The most frequent comorbidities recorded were hypertension (21%), smoking (16%), allergy (15%) and obesity (12%). Between 1996 and 2010, 125,579 adverse events were recorded, of which 34% were cardiovascular, 7% respiratory, 39% technical and 20% non-specific. The most severe events were resuscitation (50%), oliguria (22%), myocardial ischaemia (17%) and haemorrhage (10%). CONCLUSION: Routine ADS data collection contributes to the monitoring of trends in anaesthesia care in Switzerland. The ADS system has proved to be usable in daily practice, although this remains a constant challenge that is highly dependent on local quality management and quality culture. Nevertheless, success in developing routine regular feedback to users to initiate discussions about anaesthetic events would most likely help strengthen departmental culture regarding safety and quality of care.

Leadership Agenda and Strategic Progress Report, 2007-2008

Early Childhood Iowa (ECI) is an alliance of stakeholders in early care, health, and education that affect children age zero to five in the State of Iowa. Its purpose is to support a comprehensive, integrated early care, health and education system for Iowa. All activities of the system are aligned around a common vision for Iowa: Every child, beginning at birth, will be healthy and successful.Membership is voluntary and open to anyone self-identifying as a “stakeholder” in Iowa’s early care, health, and education system. The process for membership will be with as few barriers or constraints as possible. Individuals seeking membership should agree to the vision for an early care, health, and education system in Iowa and to the principles and core beliefs of the ECI Stakeholders. The structure of ECI includes six system component groups that describe the necessary elements of an effective and comprehensive early care, health, and education system, as well as a State Agency Liaison group and a Co-chairs group. Membership in each component group is open to anyone with an interest in the unique responsibilities of a implementing an early care, health and education system.

Alterations of Neuromuscular Function after the World's Most Challenging Mountain Ultra-Marathon

We investigated the physiological consequences of the most challenging mountain ultra-marathon (MUM) in the world: a 330-km trail run with 24000 m of positive and negative elevation change. Neuromuscular fatigue (NMF) was assessed before (Pre-), during (Mid-) and after (Post-) the MUM in experienced ultra-marathon runners (n = 15; finish time = 122.43 hours +/-17.21 hours) and in Pre- and Post- in a control group with a similar level of sleep deprivation (n = 8). Blood markers of muscle inflammation and damage were analyzed at Pre- and Post-. Mean +/- SD maximal voluntary contraction force declined significantly at Mid- (-13+/-17% and -10+/-16%, P<0.05 for knee extensor, KE, and plantar flexor muscles, PF, respectively), and further decreased at Post- (-24+/-13% and -26+/-19%, P<0.01) with alteration of the central activation ratio (-24+/-24% and -28+/-34% between Pre- and Post-, P<0.05) in runners whereas these parameters did not change in the control group. Peripheral NMF markers such as 100 Hz doublet (KE: -18+/-18% and PF: -20+/-15%, P<0.01) and peak twitch (KE: -33+/-12%, P<0.001 and PF: -19+/-14%, P<0.01) were also altered in runners but not in controls. Post-MUM blood concentrations of creatine kinase (3719+/-3045 Ul.1), lactate dehydrogenase (1145+/-511 UI.L-1), C-Reactive Protein (13.1+/-7.5 mg.L-1) and myoglobin (449.3+/-338.2 microg.L-1) were higher (P<0.001) than at Pre- in runners but not in controls. Our findings revealed less neuromuscular fatigue, muscle damage and inflammation than in shorter MUMs. In conclusion, paradoxically, such extreme exercise seems to induce a relative muscle preservation process due likely to a protective anticipatory pacing strategy during the first half of MUM and sleep deprivation in the second half.

Effectiveness of a brief integrative multiple substance use intervention among young men with and without booster sessions.

Brief interventions (BI) commonly employ screening and target a single substance. Multi-substance interventions are a more adequate reflection of risk behaviors in adolescents and young adults. Systematic screening complicates BI in many settings. The effectiveness of a voluntary multi-substance intervention among 19-year-old men and the incremental impact of booster sessions were analyzed. Participants were enrolled during mandatory army conscription in Switzerland. Compared with 461 controls, 392 BI subjects showed reduced substance use on 10 of 12 measures (4 tobacco, 4 cannabis, and 2 alcohol measures). Between-group effects were small and non-significant (except for cannabis use prevalence). Three-month booster sessions were not effective and even contraindicated. The usefulness of targeting multi-substances during BIs without prior screening depends on the value of small effects. The addition of booster sessions was not effective and therefore is not recommended.

"Million Dollar Baby": Eutanasia y compromiso

Million Dollar Baby no es sólo una película sobre la eutanasia. Es, también, una película sobre la dureza de la vida, la soledad y el fracaso, y sobre la ilusión, el esfuerzo y la fidelidad. Es una película donde la eutanasia aparece en su contexto y donde, por eso,podemos percibir mejor su sentido. Apenas la última media hora de la película se ocupa de la Maggie enferma que desea morir y del Frankie que duda sobre si debe ayudarla o no; pero uno puede entender mejor la situaciónde ambos cuando conoce la trayectoria de cada uno y su relación previa. Ésta, diría yo, es una primera y fundamental enseñanza de la película: los problemas asociados con la eutanasia, como cualesquiera otros problemas éticos, no pueden considerarse aisladamente.

Una vez más sobre la eutanasia

La discusión sobre la eutanasia continúa siendo una de las más candentes en el ámbito de la bioética. En este artículo, analizaremos el debate entre quienes rechazan la eutanasia amparándose en la santidad de la vida humana y quienes la defienden propugnando como ideas fundamentales la calidad de vida y la autonomía individual. Tras estas visiones enfrentadas, subyace una discusión más profunda entre una concepción antigua de los derechos humanos, basada en el respeto a un orden «natural» y una concepción moderna de los mismos, heredera de un humanismo laico, que considera la autonomía el principal valor.

Changes in lung function during an extreme mountain ultramarathon.

This study aimed to assess the effects of an extreme mountain ultramarathon (MUM, 330 km, 24,000 D+) on lung function. Twenty-nine experienced male ultramarathon runners performed longitudinally [before (pre), during (mid), and immediately after (post) a MUM] a battery of pulmonary function tests. The tests included measurements of forced vital capacity, forced expiratory volume in 1 s, peak flow, inspiratory capacity, and maximum voluntary ventilation in 12 s (MVV12). A significant reduction in the running speed was observed (-43.0% between pre-mid and mid-post; P < 0.001). Expiratory function declined significantly at mid (P < 0.05) and at post (P < 0.05). A similar trend was observed for inspiratory function (P < 0.05). MVV12 declined at mid (P < 0.05) and further decreased at post (P < 0.05). Furthermore, there are significant negative correlations between performance time and MVV12 pre-race (R = -0.54, P = 0.02) as well as changes in MVV12 between pre- and post-race (R = -0.53, P = 0.009). It is concluded that during an extreme MUM, a continuous decline in pulmonary function was observed, likely attributable to the high levels of ventilation required during this MUM in a harsh mountainous environment.

Compliance to dietary advice directed towards increasing the carbohydrate to fat ratio of the everyday diet.

OBJECTIVE: To assess the effects, on food intake, body weight and body composition, of compliance to advice aiming at increasing the carbohydrate to fat ratio of the everyday diet without imposing voluntary restriction on the amount of food consumed. DESIGN: Eight moderately overweight women (body mass index > 27 kg/m2, relative body fat mass > 30%) received dietary advice during a 2 month period. Additionally, each evening the subjects had to consume a meal artificially enriched with 13C-glucose in order to assess their compliance from the 13CO2 enrichment in expired air. MEASUREMENTS: Dietary intakes, body weight, body composition and individual compliance. RESULTS: The energy derived from fat decreased from 44 +/- 1% to 31 +/- 1% and the proportion of carbohydrate increased from 38 +/- 2% to 50 +/- 1%, whereas the absolute carbohydrate intake remained constant (182 +/- 18 g/d). Energy intake decreased by 1569 +/- 520 kJ/d. There was a net loss of fat mass (1.7 +/- 0.7 kg, P = 0.016) with fat free mass maintenance. Dietary compliance ranged from 20 to 93% (mean: 60 +/- 8%) and was positively correlated to the loss of body fat mass. CONCLUSION: Advice aiming at increasing diet's carbohydrate to fat ratio induces a loss of fat mass with fat-free mass maintenance.

Attitudes towards hastened death in ALS: A prospective study of patients and family caregivers.

Abstract Amyotrophic lateral sclerosis (ALS) may be associated with the wish to hasten death (WTHD). We aimed to determine the prevalence and stability of WTHD and end-of-life attitudes in ALS patients, identify predictive factors, and explore communication about WTHD. We conducted a prospective questionnaire study among patients and their primary caregivers attending ALS clinics in Germany and Switzerland. We enrolled 66 patients and 62 caregivers. Half of the patients could imagine asking for assisted suicide or euthanasia; 14% expressed a current WTHD at the baseline survey. While 75% were in favour of non-invasive ventilation, only 55% and 27% were in favour of percutaneous endoscopic gastrostomy and invasive ventilation, respectively. These attitudes were stable over 13 months. The WTHD was predicted by depression, anxiety, loneliness, perceiving to be a burden to others, and a low quality of life (all p < 0.05). Lower religiosity predicted whether patients could imagine assisted suicide or euthanasia. Two-thirds of patients had communicated their WTHD to relatives; no-one talked to the physician about it, yet half of them would like to do so. In conclusion, physicians should consider proactively asking for WTHD, and be sensitive towards neglected psychosocial problems and psychiatric comorbidity.

The effect of muscle fatigue on stimulus intensity requirements for central and peripheral fatigue quantification.

PURPOSE: The present study was designed to determine the stimulation intensity necessary for an adequate assessment of central and peripheral components of neuromuscular fatigue of the knee extensors. METHODS: Three different stimulation intensities (100, 120 and 150 % of the lowest intensity evoking a plateau in M-waves and twitch amplitudes, optimal stimulation intensity, OSI) were used to assess voluntary activation level (VAL) as well as M-wave, twitch and doublet amplitudes before, during and after an incremental isometric exercise performed by 14 (8 men) healthy and physically active volunteers. A visual analog scale was used to evaluate the associated discomfort. RESULTS: There was no difference (p > 0.05) in VAL between the three intensities before and after exercise. However, we found that stimulating at 100 % OSI may overestimate the extent of peripheral fatigue during exercise, whereas 150 % OSI stimulations led to greater discomfort associated with doublet stimulations as well as to an increased antagonist co-activation compared to 100 % OSI. CONCLUSION: We recommend using 120 % OSI, as it constitutes a good trade-off between discomfort and reliable measurements.

HIV testing in Switzerland.

OBJECTIVES: To obtain information about the prevalence of, reasons for, and adequacy of HIV testing in the general population in Switzerland in 1992. DESIGN: Telephone survey (n = 2800). RESULTS: Some 47% of the sample underwent one HIV test performed through blood donation (24%), voluntary testing (17%) or both (6%). Of the sample, 46% considered themselves well or very well informed about the HIV test. Patients reported unsystematic pre-test screening by doctors for the main HIV risks. People having been in situations of potential exposure to risk were more likely to have had the test than others. Overall, 85% of those HIV-tested had a relevant, generally risk-related reason for having it performed. CONCLUSIONS: HIV testing is widespread in Switzerland. Testing is mostly performed for relevant reasons. Pre-test counselling is poor and an opportunity for prevention is thus lost.

Prospective and retrospective motion correction in diffusion magnetic resonance imaging of the human brain.

Diffusion-weighting in magnetic resonance imaging (MRI) increases the sensitivity to molecular Brownian motion, providing insight in the micro-environment of the underlying tissue types and structures. At the same time, the diffusion weighting renders the scans sensitive to other motion, including bulk patient motion. Typically, several image volumes are needed to extract diffusion information, inducing also inter-volume motion susceptibility. Bulk motion is more likely during long acquisitions, as they appear in diffusion tensor, diffusion spectrum and q-ball imaging. Image registration methods are successfully used to correct for bulk motion in other MRI time series, but their performance in diffusion-weighted MRI is limited since diffusion weighting introduces strong signal and contrast changes between serial image volumes. In this work, we combine the capability of free induction decay (FID) navigators, providing information on object motion, with image registration methodology to prospectively--or optionally retrospectively--correct for motion in diffusion imaging of the human brain. Eight healthy subjects were instructed to perform small-scale voluntary head motion during clinical diffusion tensor imaging acquisitions. The implemented motion detection based on FID navigator signals is processed in real-time and provided an excellent detection performance of voluntary motion patterns even at a sub-millimetre scale (sensitivity≥92%, specificity>98%). Motion detection triggered an additional image volume acquisition with b=0 s/mm2 which was subsequently co-registered to a reference volume. In the prospective correction scenario, the calculated motion-parameters were applied to perform a real-time update of the gradient coordinate system to correct for the head movement. Quantitative analysis revealed that the motion correction implementation is capable to correct head motion in diffusion-weighted MRI to a level comparable to scans without voluntary head motion. The results indicate the potential of this method to improve image quality in diffusion-weighted MRI, a concept that can also be applied when highest diffusion weightings are performed.

Missouri River Floods After Action Report, December 20, 2011

In May 2011, very heavy rains combined with above average snowpack caused reservoirs throughout the Upper Missouri River basin to swell. The river carried more water in May and June than it does in an average year. The six Iowa counties bordering the river—Fremont, Harrison, Mills, Monona, Pottawattamie and Woodbury—suffered from major flooding which persisted throughout the spring and summer. On June 2, Governor Terry Branstad issued a Proclamation of Disaster Emergency for the six impacted counties. The Iowa Homeland Security and Emergency Management Division (HSEMD) activated the State Emergency Operations Center (SEOC) on June 10 to coordinate State, Federal, private sector, and voluntary agency preparedness and response activities in the affected area. The severity and duration of the flooding presented operational challenges for the SEOC and its partner agencies, which were further complicated by severe weather. The flooding forced the SEOC to conduct simultaneous response and recovery operations for an usually long period of time. The Missouri River floods caused major economic losses in Western Iowa. As a result of these economic losses, President Barack Obama issued a Major Disaster Declaration (FEMA-1998-DR) which made six counties eligible for Federal Public Assistance. The disaster declaration was subsequently amended on October 18, making five counties eligible for Federal Individual Assistance.
