Att möta döden : omvårdnad vid livets slut
- 2014
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Hur hanterar människan de existentiella utmaningar vi utsätts för vid livets slut? Hur kan vården underlätta för de drabbade och deras närstående? Den här boken försöker besvara dessa frågor med utgångspunkt i forskningsresultat och samtal med närstående och vårdpersonal.I Att möta döden intervjuas vårdpersonal om hanteringen av den döda kroppen, vad som händer med kroppen då vi dör och hur en obduktion kan se ut. Forskare och erfaren personal går även in på hur ett så kallat brytpunktssamtal kan gå till och vad som kan vara bra att tänka på i samtal med barn som närstående.

Tidskriftsartikel (refereegranskat)abstract
- As of today, there exist no reliable, objective methods for early detection of thrombi in the extracorporeal membrane oxygenators (ECMO) system. Within the ECMO system, thrombi are not always fixed to a certain component or location in the circuit. Thus, clot fragments of different shapes and consistencies may circulate and give rise to vibrations and sound generation. By bedside sound measurements and additional laboratory experiments (although not detailed herein), we found that the presence of particles (clots or aggregates and fragments of clots) can be detected by analyzing the strength of infra-sound (< 20 Hz) modes of the spectrum near the inlet and outlet of the centrifugal pump in the ECMO circuit. For the few patients that were considered in this study, no clear false positive or negative examples were found when comparing the spectral approach with clinical observations. A laboratory setup provided insight to the flow in and out of the pump, confirming that in the presence of particles a low-amplitude low-frequency signal is strongly amplified, enabling the identification of a clot.

Do child abuse pediatricians search for a "pediatric Vulcan planet"? : Comparison of controversies about the Vulcan-must-exist-theory and the Infant-must-have-been-shaken-theory

Tidskriftsartikel (refereegranskat)abstract
- We argue that there are similarities between the Vulcan-must-exist-theory, derived from the Original Unrestricted Newtonian Gravitational (OUNG) theory, on the one hand, and on the other hand the infant-must-have-been-shaken-theory, derived from the Original Unrestricted Abusive Head Trauma (OUAHT) theory.Although the Vulcan-must–exist-theory was apparently supported by observations over a period of 50 years, after the introduction of Einstein’s general relativity theory in 1915 and its corroboration in 1919, the alleged planet was subsequently neither observed nor needed.In analogy with the Einstein/Vulcan reasoning, we suggest that the introduction of the non-shaken baby theory by Geddes et al. in 2001-2004 indicates that in cases where an infant displays no external signs of trauma, the infant-must-have-been-shaken-theory is no longer needed.Moreover we argue that the two new theories -Einstein’s and Geddes et al.’s- have relevant similarities in terms of the effect on the respective original, unrestricted theory. Just as acceptance of Einstein’s general relativity theory led to the abandonment of the Vulcan-must-exist-theory, it is reasonable to claim that the infant-must-have-been-shaken-theory should also be abandoned. We finally argue that while the consequences of abandoning the Vulcan-must-exist-theory were restricted to some scientific and astronomical issues, the infant-must-have-been-shaken-theory has not yet been abandoned because of the societal and legal consequences.

Blood loss in exsanguination deaths
- 2011
-
Ingår i: Indian Journal of Forensic Medicine & Toxicology. - 0973-9122. ; 5:2, s. 5-8
-
Tidskriftsartikel (refereegranskat)abstract
- Deaths by exsanguination among various underlying causes of death were analyzed in order to expand the knowledge on the relation of extravasated blood volume to other documented parameters. A consecutive series of 193 cases of ruptured thoracic aortic aneurysm (n=13), gunshot wounds (n=63), stab wounds (n=28), rib fractures (n=5), and blunt injury to thoracic aorta (n=84) were investigated. The amount of internal bleeding into pleural cavities only varied greatly (200-3,400 ml) with a mean value of 1,174 ml, slightly higher among males. Age, body weight, cause and manner of death, external bleeding, alcohol inebriation, multiplicity of injuries, and degree of coronary heart disease did not significantly affect the amount of internal (pleural) bleeding. Also, post-mortem delay to autopsy did not correlated to the amount of extravasated blood, indicating that post-mortem bleeding is of no importance in these days.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Previous studies on alcohol involvement associated with fatal injury in traffic crashes have focused on the drivers, but the passenger's view is not well known. This study (1) analyzes the relationship between passenger's death and alcohol inebriation of the driver and (2) estimates the role of alcohol as the cause of a crash by examining who was at fault, sober, or inebriated.METHOD: The study includes all motor vehicle passengers (n = 420) who died in crashes in Sweden 1993 through 1996 and were medicolegally autopsied. Autopsy reports from the Departments of Forensic Medicine, including toxicological analyses, and police reports were studied. Presence of alcohol among drivers was based on blood and breath tests.RESULTS: One-fifth of the fatally injured passengers and one-fifth of the tested drivers were under the influence of alcohol. The youngest drivers had the highest prevalence of drunken driving. Drivers at fault were alcohol positive in 21% of these crashes and drivers were not at fault in 2% of these crashes. In 53% of the crashes where both the passenger and driver were alcohol positive, the passenger had a lower alcohol concentration than the driver. Children (<16 years) comprised 15% of the killed passengers. Notably, the children were riding with a driver who was under influence of alcohol in 13% of these crashes. Alcohol involvement was not tested in half of the surviving drivers.CONCLUSIONS: The data show that 20% of both passengers and drivers were under the influence of alcohol. Increased testing of surviving drivers regarding alcohol and other drugs is recommended.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: Unnatural deaths among Indigenous populations, including the Swedish Sami, occur more often than among the general population. To find prevention strategies, we explored the circumstances of the unnatural deaths of members of reindeer-herding Sami families.STUDY DESIGN: The number of deaths from among a cohort of 7,482 members of reindeer-herding Sami families were retrieved from the National Board of Health and Welfare for the years 1961- 2001.METHODS: An evaluation of the information from autopsy records at the National Board of Forensic Medicine, police reports, and available medical records identified 158 unnatural deaths. These were then analysed in detail.RESULTS: Transport-related deaths and suicides were the most common unnatural deaths among Swedish reindeer-herding Sami family members. Suicides contributed to 23% of all deaths, road traffic accidents to 16%, and snowmobile fatalities to 11%. The accidents generally reflected an "outdoor lifestyle" and the working conditions were characterized by the use of off-road vehicles such as snowmobiles. Half of the number of victims tested positive for alcohol and alcohol abuse was documented in 15% of all victims.CONCLUSIONS: The results indicate that alcohol is an important factor in preventing unnatural deaths among reindeer-herding Sami, together with increased safety of both on-road and off-road transportation.

An epidemiological perspective on heart and lung weight in cardiac and intoxication deaths
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The main purpose of a medico-legal autopsy is to determine the cause and manner of death. A forensic pathologist makes assessments of this using several sources of information, one of which is the discrepancy between measured organ weight and reference values. Of particular interest is the heart weight in heart disease and the weight of the lungs in fatal intoxications. In this thesis, a linear model of lung weight was created, but the model could at best explain only 13% of the variation in combined lung weight (Paper I). Unsurprisingly, this meant that the model was a poor definition of “normal” lung weight and could not be used to identify intoxication cases (Paper II). A ratio of lung weight to heart weight (LWHW ratio) also failed to differentiate intoxication cases from controls. The poor performance of these methods could plausibly have been due to fatal intoxications with only some substances being associated with increased lung weight, but an analysis showed that many common intoxicants were associated with heavier lungs than hanging deaths (Paper III). To establish heart weight references more applicable in a medico-legal autopsy population, a model of heart weight accounting for undiagnosed cardiac hypertrophy was created (Paper IV). The model showed that for a decedent of average the evidence that a was hypertrophic reached, substantial support at around 470 g.In conclusion, a definition of “heavy lungs” remains elusive. However, it seems to be a finding compatible with fatal intoxications with many substances and the low predictive value found may be due to study design. The heart weight model presented allows pathologists to assess the evidence of cardiac hypertrophy more easily than previously published models.

Cardiac enlargement in a medicolegal autopsy setting
- 2023
-
Ingår i: American Journal of Forensic Medicine and Pathology. - : Wolters Kluwer. - 0195-7910 .- 1533-404X. ; 44:4, s. 267-272

Tidskriftsartikel (refereegranskat)abstract
- A key element for diagnosing cardiac enlargement in an autopsy setting is relevant heart weight references. However, most available references are to a large extent not representative of a medicolegal autopsy population, implying that reference weights are likely lower than those in the relevant population.To establish more applicable heart weight references in a medicolegal autopsy population, we designed a heart weight model that accounts for undiagnosed cardiac enlargement using data from 11,897 nontraumatic Swedish medicolegal autopsy cases autopsied between 2010 and 2019. The model was validated in 296 nonobese young adult suicidal hanging cases.For a decedent of average height (174 cm), the evidence that a heart weight was enlarged reached weak support at approximately 430 g, substantial support at approximately 480 g, and strong support at 520 g. The modeled prevalence of cardiac enlargement was very high among elderly and obese decedents.We believe that our model is more applicable in a medicolegal setting than those previously published. The presented quantification of the degree of uncertainty regarding diagnosis can help the pathologist in diagnosing cardiac enlargement. To facilitate the use of this model, we also made it available through a simple online tool (https://formedum.shinyapps.io/HeartWeightCalc/).
