Illness perceptions of leprosy-cured individuals in Surinam with residual disfigurements – “I am cured, but still I am ill”

Objective Leprosy has rarely been the subject of health psychology research despite its substantial impact. Our aim was to explore illness perceptions in patients and their health care providers in Surinam. The Common Sense Model (CSM) was the guiding theoretical model. Design Patients with biomedically cured leprosy and their health care providers completed the B-IPQ and took part in semi-structured interviews. The literature on illness perceptions in patients with leprosy was reviewed. Main outcome measures Patients’ B-IPQ scores were compared with samples of patients with other (chronic) illnesses, and with health care providers completing the questionnaire as if they were visibly disfigured patients. Quotations from the semi-structured interviews were used to contextualise the illness perceptions. Results Patients’ B-IPQ scores reflected the chronic nature of leprosy and were comparable with those with other chronic illnesses. Health care providers perceived leprosy to have a greater negative impact than did the patients. Perceived understanding of causes differed considerably between patients and health care providers. Conclusion Leprosy continues to be experienced as an illness with major psychological and social consequences such as stigmatisation, even after biomedical cure. Interventions that target patients, health care providers, and society at large may help reduce perceived shame and stigma. The CSM is a helpful theoretical model in studying this population. </jats:sec

Evolution of traditional taboos in Suriname

Traditional taboos have persisted in Suriname, thanks to the sustainability of African culture in Maroon communities in the interior of the country. A conceptual dichotomy emerged in the 19th and early 20th centuries coinciding with two geographical regions: in the coastal region, ‘trefu’, a food taboo, practised mainly by Creoles, violation of which was thought to result in contracting leprosy, and in the interior ‘tyina’, a ‘broader’ taboo concept (food, places, actions) practised by Maroons. Recent research indicates the dichotomy is weakening, reflected in a declining belief in the trefu-leprosy relation and a merging of ‘trefu’ and ‘tyina’, exchange of taboo practices between ethnic groups and declining adherence of youngsters to taboos. The migration of Maroons to the coastal region and creolisation appear to be driving forces behind these processes, whilst the decline in leprosy incidence may also have contributed. Additional research is needed to understand the evolution of traditional taboos in Suriname and the Greater Caribbean

Decolonizing social sciences in Suriname: a strategic view in favor of regionalism

Social sciences research about Suriname is euro-centric. It is dominated by the Dutch and evolved in the context of academic colonialism. From the Surinamese point of view, this situation is undesired. Some lessons can be learned from others, e.g. South East Asian and New Zealand/Maori scientific communities. In order to decolonize research it is suggested that the Surinamese social scientists community is strengthened and that cooperation with institutions in the South-American and Caribbean region is intensified. To achieve sustainability in a regional context concerted action of social scientists and academic institutions is required. The focus in this article is on cooperation with Brazil, the Southern neighbor of Suriname and a leading nation in the region. Referring to common factors in history and current social developments in Suriname and Brazil, it is suggested that the cooperation that started in the last decades of the 20th century is intensified

Perception of a conserved family of plant signalling peptides by the receptor kinase HSL3

Plant genomes encode hundreds of secreted peptides; however, relatively few have been characterised. We report here an uncharacterised, stress‐induced family of plant signalling peptides, which we call CTNIPs. Based on the role of the common co‐receptor BRASSINOSTEROID INSENSITIVE 1‐ASSOCIATED KINASE 1 (BAK1) in CTNIP‐induced responses, we identified in Arabidopsis thaliana the orphan receptor kinase HAESA‐LIKE 3 (HSL3) as the CTNIP receptor via a proteomics approach. CTNIP binding, ligand‐triggered complex formation with BAK1, and induced downstream responses all involve HSL3. Notably, the HSL3‐CTNIP signalling module is evolutionarily conserved amongst most extant angiosperms. The identification of this novel signalling module will further shed light on the diverse functions played by plant signalling peptides and will provide insights into receptor-ligand co‐evolution

High prevalence of non-accidental trauma among deceased children presenting at Level I trauma centers in the Netherlands

PURPOSE: Between 0.1—3% of injured children who present at a hospital emergency department ultimately die as a result of their injuries. These events are typically reported as unnatural causes of death and may result from either accidental or non-accidental trauma (NAT). Examples of the latter include trauma that is inflicted directly or resulting from neglect. Although consultation with a forensic physician is mandatory for all deceased children, the prevalence of fatal inflicted trauma or neglect among children is currently unclear. METHODS: This is a retrospective study that included children (0–18 years) who presented and died at one of the 11 Level I trauma centers in the Netherlands between January 1, 2014, and January 1, 2019. Outcomes were classified based on the conclusions of the Child Abuse and Neglect team or those of forensic pathologists and/or the court in cases referred for legally mandated autopsies. Cases in which conclusions were unavailable and there was no clear accidental cause of death were reviewed by an expert panel. RESULTS: The study included 175 cases of childhood death. Seventeen (9.7%) of these children died due to inflicted trauma (9.7%), 18 (10.3%) due to neglect, and 140 (80%) due to accidents. Preschool children (< 5 years old) were significantly more likely to present with injuries due to inflicted trauma and neglect compared to older children (44% versus 6%, p < 0.001, odds ratio [OR] 5.80, 95% confidence interval [CI] 2.66–12.65). Drowning accounted for 14 of the 18 (78%) pediatric deaths due to neglect, representing 8% of the total cases. Postmortem radiological studies and autopsies were performed on 37 (21%) of all cases of childhood death. CONCLUSION: One of every five pediatric deaths in our nationwide Level I trauma center study was attributed to NAT; 44% of these deaths were the result of trauma experienced by preschool-aged children. A remarkable number of fatal drownings were due to neglect. Postmortem radiological studies and autopsies were performed in only one-fifth of all deceased children. The limited use of postmortem investigations may have resulted in missed cases of NAT, which will result in an overall underestimation of fatal NAT experienced by children.

Secular and race/ethnic trends in glycemic outcomes by BMI in US adults: The role of waist circumference

Background: For the same body mass index (BMI) level, waist circumference (WC) is higher in more recent years. How this impacts diabetes and prediabetes prevalence in the United States and for different race/ethnic groups is unknown. We examined prevalence differences in diabetes and prediabetes by BMI over time, investigated whether estimates were attenuated after adjusting for waist circumference, and evaluated implications of these patterns on race/ethnic disparities in glycemic outcomes. Methods: Data came from 12 614 participants aged 20 to 74 years from the National Health and Nutrition Examination Surveys (1988-1994 and 2007-2012). We estimated prevalence differences in diabetes and prediabetes by BMI over time in multivariable models. Relevant interactions evaluated race/ethnic differences. Results: Among normal, overweight, and class I obese individuals, there were no significant differences in diabetes prevalence over time. However, among individuals with class II/III obesity, diabetes prevalence rose 7.6 percentage points in 2007-2012 vs 1988-1994. This estimate was partly attenuated after adjustment for mean waist circumference but not mean BMI. For prediabetes, prevalence was 10 to 13 percentage points higher over time at lower BMI values, with minimal attenuation after adjustment for WC. All patterns held within race/ethnic groups. Diabetes disparities among blacks and Mexican Americans relative to whites remained in both periods, regardless of BMI, and persisted after adjustment for WC. Conclusions: Diabetes prevalence rose over time among individuals with class II/III obesity and may be partly due to increasing waist circumference. Anthropometric measures did not appear to account for temporal increases in prediabetes, nor did they attenuate race/ethnic disparities in diabetes. Reasons underlying these trends require further investigation

Subtilase-mediated biogenesis of the expanded family of SERINE RICH ENDOGENOUS PEPTIDES

Plant signalling peptides are typically released from larger precursors by proteolytic cleavage to regulate plant growth, development and stress responses. Recent studies reported the characterization of a divergent family of Brassicaceae-specific peptides, SERINE RICH ENDOGENOUS PEPTIDES (SCOOPs), and their perception by the leucine-rich repeat receptor kinase MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2 (MIK2). Here, we reveal that the SCOOP family is highly expanded, containing at least 50 members in the Columbia-0 reference Arabidopsis thaliana genome. Notably, perception of these peptides is strictly MIK2-dependent. How bioactive SCOOP peptides are produced, and to what extent their perception is responsible for the multiple physiological roles associated with MIK2 are currently unclear. Using N-terminomics, we validate the N-terminal cleavage site of representative PROSCOOPs. The cleavage sites are determined by conserved motifs upstream of the minimal SCOOP bioactive epitope. We identified subtilases necessary and sufficient to process PROSCOOP peptides at conserved cleavage motifs. Mutation of these subtilases, or their recognition motifs, suppressed PROSCOOP cleavage and associated overexpression phenotypes. Furthermore, we show that higher-order mutants of these subtilases show phenotypes reminiscent of mik2 null mutant plants, consistent with impaired PROSCOOP biogenesis, and demonstrating biological relevance of SCOOP perception by MIK2. Together, this work provides insights into the molecular mechanisms underlying the functions of the recently identified SCOOP peptides and their receptor MIK2
