Obesity and the vitality of food in Finland, ca. 1950-1970.

Mainstream and alternative nutrition doctrines have crucially shaped our understanding of the vital aspects of and forces in human nutrition. Drawing upon a diverse array of sources, this article delves into cultural, social, and scientific conceptions of vital nutrition and how they evolved in relation to the Finnish obesity discourse from the 1950s to the 1970s. The Association to Combat Obesity (ACO), which brought together nutrition scientists, food faddists and laypeople, was the driving force of these debates. In the context of this article, food was perceived to influence the vitality of individuals and nations through its effect on body weight. Obese bodies seemed to conflict with both utopian visions of bodily transcendence and the ideals of wellbeing in modern health sciences. This work highlights the ideological continuities between interwar and postwar nutrition debates as well as the persistent tensions between scientific advancements and alternative nutrition philosophies. They have molded the conceptions of vitality and attitudes towards obesity. Concludingly, we suggest that the social responses to obesity have been influenced by the condition's perceived adverse relationship to vitality, in which fat has acted as a persistent reminder of corporeality, death, and decay.

The History of Psychiatric Epidemiology in Finland: From National Needs to International Arenas, 1900s-1990s.

Psychiatric epidemiology has significantly influenced public health policies all around the world. This article discusses how Finnish epidemiologists reacted to local needs, which were born in specific circumstances and were controlled by science policy and funding opportunities. The development between the 1900s and 1990s is divided into three stages. The first Finnish studies in the field focused on the prevalence of mental illnesses in the country. The focus was to gain information for service planning, most of all to estimate the need for new hospitals and to set up the national social insurance system. After the Second World War, structural changes and social engineering fueled epidemiological interest. From the 1960s until the late 1980s, psychiatric epidemiology was interconnected with social psychiatry, which held a strong position in Finland. Since the 1990s, Finnish psychiatric epidemiology has been integrated with international epidemiology by using shared methodologies and through participation in transnational studies.

A Deep Learning-Based Automated CT Segmentation of Prostate Cancer Anatomy for Radiation Therapy Planning-A Retrospective Multicenter Study.

A commercial deep learning (DL)-based automated segmentation tool (AST) for computed tomography (CT) is evaluated for accuracy and efficiency gain within prostate cancer patients. Thirty patients from six clinics were reviewed with manual- (MC), automated- (AC) and automated and edited (AEC) contouring methods. In the AEC group, created contours (prostate, seminal vesicles, bladder, rectum, femoral heads and penile bulb) were edited, whereas the MC group included empty datasets for MC. In one clinic, lymph node CTV delineations were evaluated for interobserver variability. Compared to MC, the mean time saved using the AST was 12 min for the whole data set (46%) and 12 min for the lymph node CTV (60%), respectively. The delineation consistency between MC and AEC groups according to the Dice similarity coefficient (DSC) improved from 0.78 to 0.94 for the whole data set and from 0.76 to 0.91 for the lymph nodes. The mean DSCs between MC and AC for all six clinics were 0.82 for prostate, 0.72 for seminal vesicles, 0.93 for bladder, 0.84 for rectum, 0.69 for femoral heads and 0.51 for penile bulb. This study proves that using a general DL-based AST for CT images saves time and improves consistency.
