Abstract Using postmortem CT (PMCT), changes in the volume of the lateral cerebral ventricles (LCVs) and modifications of the radiodensity of cerebrospinal fluid (CSF) have been examined to identify a possible relationship between these changes and the time of death. Subsequent periodical CT scans termed “sequential scans” for ten corpses at known time of death were obtained, and a 3D segmentation of the entire LCV was carried out to measure its volume and radiodensity over time from ~ 5.5- h up to 273-h postmortem. A linear decrease of the LCV volume for all the cases was observed in the investigated time range, together with an overall logarithmic increase of radiodensity. Although a larger sampling should be performed to improve the result reliability, our finding suggests that the postmortem variation of CSF radiodensity can be a potentially useful tool in determining postmortem interval, a finding that is worthy of further investigation.

Background: Suicide-bereaved individuals represent an important group impacted by suicide. Understanding their experiences following the suicide of a loved one is an important research domain, despite receiving limited attention. Although suicide-bereaved individuals may benefit from mental health treatment, their attitudes toward therapy and therapists are poorly understood. Aims: The present study aimed to understand the extent to which bereaved individuals’ attitudes toward therapy and therapists are impacted by whether their loved one was in therapy at the time of death. Method: Suicide-bereaved individuals (N = 243) from the United States were recruited to complete an online survey about their experience with and attitudes toward therapy and therapists following the suicide of a loved one. Results: Bereaved individuals whose loved one was in therapy at the time of death (N = 48, 19.8%) reported more negative and less positive attitudes toward the treating therapist than those whose loved one was not in therapy at the time of death (N = 81, 33.3%) or whose loved one was never in therapy/the deceased’s therapy status was unknown (N = 114, 46.9%). Conclusion: The deceased’s involvement with a therapist appears to be an important factor impacting the experience of bereaved individuals and should be considered when attempting to engage these individuals in postvention.

Anecdotal reports of deceased celebrities being found nude abound, yet research is lacking regarding the frequency of nudity at death. Moreover, it is unknown if nudity at the time of death is a useful investigative clue or a distracting non-factor in equivocal death cases. This study used data from 119,145 homicides and suicides reported to the Centers for Disease Control to explore victim nudity, prior life stressors, and demographics on the likelihood of a death being a homicide or a suicide. Logistic regression results indicate that a female victim being found nude is a strong indicator of homicide.

Chronothanatology has always been a challenge in forensic sciences. Therefore, the importance of a multidisciplinary approach for the characterization of matrices (organs, tissues, or fluids) that respond linearly to the postmortem interval (PMI) is emerging increasingly. The vitreous humor is particularly suitable for studies aimed at assessing time-related modifications because it is topographically isolated and well-protected. In this work, a novel approach based on thermogravimetry and chemometrics was used to estimate the time since death in the vitreous humor and to collect a databank of samples derived from postmortem examinations after medico–legal evaluation. In this study, contaminated and uncontaminated specimens with tissue fragments were included in order to develop a classification model to predict time of death based on partial least squares discriminant analysis (PLS-DA) that was as robust as possible. Results demonstrate the possibility to correctly predict the PMI even in contaminated samples, with an accuracy not lower than 70%. In addition, the correlation coefficient of the measured versus predicted outcomes was found to be 0.9978, confirming the ability of the model to extend its feasibility even to such situations involving contaminated vitreous humor.

Abstract Most existing studies have examined the relationship between social support and health in cross-sectional data. However, the changing dynamics of social support over time and its relationship with all-cause mortality have not been well explored. Using data from the Pine Study (N = 3,157), this study examined whether social support was associated with time of death at an 8 years follow-up among older Chinese Americans. Social support from a spouse, family members and friend were collected at the baseline using an HRS social support scale. Perceived social support and time of death were ascertained from the baseline through wave 4. Cox proportional hazard models were used to assess associations of perceived support with the risk of all-cause mortality using time-varying covariate analyses. Covariates included age, sex, education, income, and medical comorbidities. All study participants were followed up for 8 years, during which 492 deaths occurred. In multivariable analyses, the results showed that positive family support [HR 0.91; 95% CI (0.86, 0.98)] and overall social support [HR 0.95; 95% CI (0.92,0.98)] were significantly associated with a lower risk of 8-year mortality. Results demonstrate robust association in which perceived positive family and overall social support over time had a protective effect on all-cause mortality risk in older Chinese Americans. Interventions could focus on older adults with low social support and protect their health and well-being. Future studies could further explore why social support from family is different from social support from other sources regarding mortality risk in older Chinese Americans.

Abstract Background It is widely recognised, that family members are central to care of people with advanced illness, and that support should be provided to all family members in need thereof. The aim of this study was to investigate family members’ experiences of support received during the last three months of life, at the time of death and after the death of a person with advanced illness. Methods A retrospective cross-sectional survey design was employed, using the VOICES(SF) questionnaire and multiple methods for data analyses. The sample consisted of 485 bereaved family members (aged: 20–90 years old, 70% women) of people who died in hospital between August 2016-April 2017. Results Of the family members, 58,8% reported they had received enough help and support during the illness, whereas 30,2% had not. Family members’ comments about support during the illness were mainly related to care the ill person had or had not received, rather than about support they themselves received. Of all family members, 52,8% reported having had enough support at the time of the ill person’s death. Related to support at death, 14,6% reported that the imminence of death was not clear, which was described as having affected their opportunity to be with the dying person at the time of death. Of all, 25,2% had a follow-up conversation after the death, 48% did not and did not want to, and 21% had no follow-up conversation, but would have liked one. A follow-up conversation was described as helpful for the bereavement process, and disappointment was expressed when not receiving support after the death. Conclusions Family members’ experiences of support were partly related to whether the ill person’s care needs were fulfilled. Healthcare staff expressing empathy and respect in the care of dying people and their family members were important for family members’ experiences of support. Family members’ difficulty recognising that death was imminent and the importance of healthcare staff providing them with clear information were expressed in connection with support at death. Follow-up conversations were valued by family members, especially if with a healthcare professional who was present at the time of death.

By courtesy of the Government Actuary, the preliminary crude data relating to the proposed English Life Tables (No. 13) were made available to the authors. In this paper various graduations derived from these data “are described and an outline is given of the salient features of each.The investigation covered the calendar years 1970, 1971, and 1972. For each integer x ≥ 2 the values of θx, the number of deaths during the investigation period aged x last birthday at the time of death, and Exc, the corresponding central exposure to risk, were available for both sexes. The central exposures to risk were obtained using population totals from the 1971 national census, by a method similar to that described in Appendix I of reference 4.
