A Comparison of Adverse Short-Term Outcomes After Forefoot Amputation Based on Patient Height.

BACKGROUND: The objective of this investigation was to evaluate adverse short-term outcomes after partial forefoot amputation with a specific comparison performed based on patient height. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was analyzed to select patients with a 28805 Current Procedural Terminology code (amputation, foot; transmetatarsal) who underwent the procedure with "all layers of incision (deep and superficial) fully closed." This resulted in 11 patients with a height of 60 inches or less, 202 with a height greater than 60 inches and less than 72 inches, and 55 with a height of 72 inches or greater. RESULTS: Results of the primary outcome measures found no significant differences among groups with respect to the development of a superficial surgical site infection (0% versus 6.4% versus 5.5%; P = .669), deep incisional infection (9.1% versus 3.5% versus 10.9%; P = .076), or wound disruption (0% versus 5.4% versus 5.5%; P = .730). In addition, no significant differences were observed among groups with respect to unplanned reoperations (9.1% versus 16.8% versus 12.7%; P = .630) or unplanned hospital readmissions (45.5% versus 23.3% versus 20.0%; P = .190). CONCLUSIONS: The results of this investigation demonstrate no differences in short-term adverse outcomes after partial forefoot amputation with primary closure based on patient height. Although height has previously been described as a potential risk factor in the development of lower-extremity pathogenesis, this finding was not observed in this study from a large US database.

Genetic influence on within-person longitudinal change in anthropometric traits in the UK Biobank.

The causes of temporal fluctuations in adult traits are poorly understood. Here, we investigate the genetic determinants of within-person trait variability of 8 repeatedly measured anthropometric traits in 50,117 individuals from the UK Biobank. We found that within-person (non-directional) variability had a SNP-based heritability of 2-5% for height, sitting height, body mass index (BMI) and weight (P ≤ 2.4 × 10-3). We also analysed longitudinal trait change and show a loss of both average height and weight beyond about 70 years of age. A variant tracking the Alzheimer's risk APOE- E 4 allele (rs429358) was significantly associated with weight loss ( ß = -0.047 kg per yr, s.e. 0.007, P = 2.2 × 10-11), and using 2-sample Mendelian Randomisation we detected a relationship consistent with causality between decreased lumbar spine bone mineral density and height loss (bxy = 0.011, s.e. 0.003, P = 3.5 × 10-4). Finally, population-level variance quantitative trait loci (vQTL) were consistent with within-person variability for several traits, indicating an overlap between trait variability assessed at the population or individual level. Our findings help elucidate the genetic influence on trait-change within an individual and highlight disease risks associated with these changes.

Stunting and its association with education and cognitive outcomes in adulthood: A longitudinal study in Indonesia.

BACKGROUND: Stunting is associated with adverse outcomes in adulthood. This article specifically aims to analyse the relationship between childhood stunting and education as well as cognitive outcomes for adults in Indonesia. METHODS: Pooled data from wave one (1) and two (2) of the Indonesia Family Life Survey (IFLS) in 1993 and 1997 identified a sub-sample of 4,379 children aged 0-5 by their height-for-age (HAZ) to be compared for their differences in educational outcomes and cognitive abilities in 2014. HAZ was used to proxy relative height to determine stunting status based on 2006 WHO child's growth standards. Education and cognitive abilities outcomes include years of schooling, age of school entry, grade repetition, and scores for cognitive and math tests. The study employs estimation models of pooled regressions and instrumental variable (IV) to address problems of endogeneity and bias from omitted variables. RESULTS: Stunting and relatively small stature had significant associations with cognitive development, and they worked as intermediaries to cognitive developmental barriers as manifested in reduced educational outcomes. A lack of one SD in HAZ was associated with 0.6 years shortened length of the school, 3% higher chances of dropouts from secondary school, and 0.10-0.23 SD lowered cognitive and numerical scores. Similarly, stunting is associated with decrease cognitive test scores by 0.56-0.8 SD compared to non-stunting, two years less schooling, and 0.4 years of delayed entry to school. As for cognitive abilities, stunting is associated with lower cognitive and numerical abilities by 0.38-0.82 z-scores. CONCLUSION: Growth retardation during childhood in Indonesia was associated with lower cognitive abilities, particularly during school age, and this correlation faded as individuals grew up. Subsequently, growth retardation is significantly linked to lower educational outcomes. Impaired growth has implications for reduced lifetime earnings potential mediated by diminished cognitive capacity and lower educational attainment. The finding suggests that development in Indonesia during recent decades has not provided an adequate environment to enable children to achieve their potential educational outcomes.

The utility of sternum in creating a biological profile: A review and future directions.

This review delves into the forensic utility of the sternum in creating a biological profile, focusing on sex, stature, and age estimation. Emphasizing the sternum's significance in challenging scenarios, the study supports the combined length of the manubrium and sternal body as a crucial indicator in sex and stature estimation. However, it highlights the need for caution in applying findings across diverse populations and questions the reliability of Hyrtl's law. Age estimation, primarily based on morphological changes and ossification ages, is explored, with one study showing promise but requiring further validation. While acknowledging the sternum's advantages, the review underscores potential limitations and the absence of specific studies on ancestry estimation, leaving this aspect open for future research. In conclusion, the review provides a comprehensive overview of the sternum's forensic applications, urging continued research to enhance accuracy and applicability.

Insulin-like growth factor 1 and sex hormones for assessment of anthropometric and pubertal growth of Egyptian children and adolescents with type 1 diabetes mellitus (single center study).

BACKGROUND: This study aimed to assess the anthropometric measures and pubertal growth of children and adolescents with Type 1 diabetes mellitus (T1DM) and to detect risk determinants affecting these measures and their link to glycemic control. PATIENTS AND METHODS: Two hundred children and adolescents were assessed using anthropometric measurements. Those with short stature were further evaluated using insulin-like growth factor 1 (IGF-1), bone age, and thyroid profile, while those with delayed puberty were evaluated using sex hormones and pituitary gonadotropins assay. RESULTS: We found that 12.5% of our patients were short (height SDS < -2) and IGF-1 was less than -2 SD in 72% of them. Patients with short stature had earlier age of onset of diabetes, longer duration of diabetes, higher HbA1C and urinary albumin/creatinine ratio compared to those with normal stature (p < 0.05). Additionally, patients with delayed puberty had higher HbA1c and dyslipidemia compared to those with normal puberty (p < 0.05). The regression analysis revealed that factors associated with short stature were; age at diagnosis, HbA1C > 8.2, and albumin/creatinine ratio > 8 (p < 0.05). CONCLUSION: Children with uncontrolled T1DM are at risk of short stature and delayed puberty. Diabetes duration and control seem to be independent risk factors for short stature.

Effectiveness of leuprolide acetate administered monthly compared to three-monthly in the treatment of central precocious puberty: evaluation at the end of treatment.

Introduction: Gonadotropin-releasing hormone (GnRH) analogs are the standard treatment for central precocious puberty (CPP). Although there are numerous varieties of GnRH agonists, the effectiveness of 1-monthly compared with 3-monthly Leuprolide acetate is still restricted. The objective of this study was to evaluate the outcomes of CPP treatment with Leuprolide acetate at a 1-monthly dosage of 3.75 mg, in comparison to a dosage of 11.25 mg administered every 3 months. Method: This retrospective cohort study involved 143 girls diagnosed with CPP with 72 of them receiving the monthly treatment regimen and 71 receiving the 3-monthly treatment regimen. Anthropometric measurements were compared at the start and end of the therapy. The rates and level of LH suppression were assessed six months after therapy. Results: The regimen administered every 3 months showed more significant suppression of LH. The 3-monthly group showed lower actual height and degree of bone age advancement at the end of therapy. However, the predicted adult height (PAH) remained comparable in both groups. Conclusion: The 3-monthly treatment showed greater hormonal and growth suppression effects, but there was no significant difference in PAH between the two groups.

Nutrition and Epstein-Barr viremia in children underwent liver transplantation: A retrospective, cross-sectional study.

BACKGROUND AND AIMS: We aimed to examine the association between nutritional status, assessed by height/length and body weight for age and sex, and Epstein-Barr virus (EBV) viremia in children underwent liver transplantation. METHODS: Nutritional status was determined by total score of age- and sex-specific height/length and body weight: < (-2 SD) as "2 points", (-2 SD to -1 SD) as "1 point", and ≥ (-1SD) as "0 point". Children were further classified into three groups: malnutrition (4 points), risk of malnutrition (1-3 points), and normal (0 point). EBV viremia were confirmed by real time quantitative PCR method if EBV burden was ≥400 copies/ml. RESULTS: A total number of 896 children (414 boys and 482 girls, medium age 8 months) were included in the study. The medium height was 65.0 cm while medium body weight was 7.0 kg. The prevalence of EBV viremia was 54.6% during follow up. Comparing with children with normal nutritional status, the adjusted odds ratios for the risk of EBV viremia was 2.14 (95% CI: 1.44, 3.19) in children with risk of malnutrition, and 2.29 (95% CI: 1.54, 3.40) in children with malnutrition. Each point increase of nutritional score was associated with a 21% higher risk of EBV viremia (odd ratios = 1.21; 95% CI: 1.10, 1.34) in fully adjusted model. CONCLUSIONS: Nutritional score was associated with EBV viremia in children underwent liver transplantation.

Secular trends in physical growth, biological maturation, and intelligence in children and adolescents born between 1978 and 1993.

Introduction: Human physical growth, biological maturation, and intelligence have been documented as increasing for over 100 years. Comparing the timing of secular trends in these characteristics could provide insight into what underlies them. However, they have not been examined in parallel in the same cohort during different developmental phases. Thus, the aim of this study was to examine secular trends in body height, weight, and head circumference, biological maturation, and intelligence by assessing these traits concurrently at four points during development: the ages of 4, 9, 14, and 18 years. Methods: Data derived from growth measures, bone age as an indicator of biological maturation, and full-scale intelligence tests were drawn from 236 participants of the Zurich Longitudinal Studies born between 1978 and 1993. In addition, birth weight was analyzed as an indicator of prenatal conditions. Results: Secular trends for height and weight at 4 years were positive (0.35 SD increase per decade for height and an insignificant 0.27 SD increase per decade for weight) and remained similar at 9 and 14 years (height: 0.46 SD and 0.38 SD increase per decade; weight: 0.51 SD and 0.51 SD increase per decade, respectively) as well as for weight at age 18 years (0.36 SD increase per decade). In contrast, the secular trend in height was no longer evident at age 18 years (0.09 SD increase per decade). Secular trends for biological maturation at 14 years were similar to those of height and weight (0.54 SD increase per decade). At 18 years, the trend was non-significant (0.38 SD increase per decade). For intelligence, a positive secular trend was found at 4 years (0.54 SD increase per decade). In contrast, negative secular trends were observed at 9 years (0.54 SD decrease per decade) and 14 years (0.60 SD decrease per decade). No secular trend was observed at any of the four ages for head circumference (0.01, 0.24, 0.17, and - 0.04 SD increase per decade, respectively) and birth weight (0.01 SD decrease per decade). Discussion: The different patterns of changes in physical growth, biological maturation, and intelligence between 1978 and 1993 indicate that distinct mechanisms underlie these secular trends.

Age- and height-dependent bias of underweight and overweight assessment standards for children and adolescents.

Background: Precision in evaluating underweight and overweight status among children and adolescents is paramount for averting health and developmental issues. Existing standards for these assessments have faced scrutiny regarding their validity. This study investigates the age and height dependencies within the international standards set by the International Obesity Task Force (IOTF), relying on body mass index (BMI), and contrasts them with Japanese standards utilizing the percentage of overweight (POW). Method: We scrutinized a comprehensive database comprising 7,863,520 children aged 5-17 years, sourced from the School Health Statistics Research initiative conducted by Japan's Ministry of Education, Culture, Sports, Science, and Technology. Employing the quantile regression method, we dissected the structure of weight-for-height distributions across different ages and sexes, quantifying the potentially biased assessments of underweight and overweight status by conventional criteria. Results: Applying IOFT criteria for underweight assessment revealed pronounced height dependence in males aged 11-13 and females aged 10-11. Notably, a discernible bias emerged, wherein children in the lower 25th percentile were classified as underweight five times more frequently than those in the upper 25th percentile. Similarly, the overweight assessment displayed robust height dependence in males aged 8-11 and females aged 7-10, with children in the lower 25th percentile for height deemed obese four or five times more frequently than their counterparts in the upper 25th percentile. Furthermore, using the Japanese POW criteria for assessment revealed significant age dependence in addition to considerably underestimating the percentage of underweight and overweight cases under the age of seven. However, the height dependence for the POW criterion was smaller than the BMI criterion, and the difference between height classes was less than 3-fold. Conclusion: Our findings underscore the intricacies of age-dependent changes in body composition during the growth process in children, emphasizing the absence of gold standards for assessing underweight and overweight. Careful judgment is crucial in cases of short or tall stature at the same age, surpassing sole reliance on conventional criteria results.

The Suitable Population for Opportunistic Low Bone Mineral Density Screening Using Computed Tomography.

Objective: To explore the suitable population of CT value for predicting low bone mineral density (low-BMD). Methods: A total of 1268 patients who underwent chest CT examination and DXA within one-month period retrospectively analyzed. The CT attenuation values of trabecular bone were measured in mid-sagittal plane from thoracic vertebra 7 (T7). Receiver operating characteristic (ROC) curves were used to evaluate the ability to diagnose low-BMD. Results: The AUC for diagnosing low BMD was larger in women than in men (0.894 vs 0.744, p < 0.05). The AUC increased gradually with the increase of age but decreased gradually with the increase in height and weight (p < 0.05). In females, when specificity was adjusted to approximately 90%, a threshold of 140.25 HU has a sensitivity of 69.3%, which is higher than the sensitivity of 36.5% in males for distinguishing low-BMD from normal. At the age of 70 or more, when specificity was adjusted to approximately 90%, a threshold of 126.31 HU has a sensitivity of 76.1%, which was higher than that of other age groups. Conclusion: For patients who had completed chest CTs, the CT values were more effective in predicting low-BMD in female, elderly, lower height, and lower weight patients.

Evolving growth hormone deficiency: proof of concept.

Introduction: We present the evolution of GHD in adolescent males with persistent growth failure, in whom the diagnosis was established after a second GH stimulation test (GST). Methods: We performed a retrospective chart review of children who presented for short stature (height less < 2SD for mean/mid-parental height) and/or growth failure (sustained growth velocity < 0 SD) to pediatric endocrinology at Mount Sinai Kravis Children's Hospital, New York and who had 2 GSTs. Data collected from electronic medical records were analyzed using SPSS v28.0. Results: Of 53 patients included, 42 were males. Average GH peak on initial GST was 15.48 ± 4.92 ng/ml, at 10.07 ± 2.65 years, mean height -1.68 ± 0.56SD(28% had <2SD), IGF-1 -1.00 ± 0.88SD. After 2.23 ± 1.22 years, at 12.04 ± 2.41years, height SDs decreased to -1.82 ± 0.63SD and IGF-1 was -1.08 ± 0.84SD. At repeat GST, average GH peak was 7.59 ± 2.12 ng/dL, with 36% ≤7 ng/dl and 32% in puberty. 12 males reached adult height of 0.08 ± 0.69 SD with a mean height gain of 1.83 ± 0.56SD(p<0.005), IGF-1 of -1.15 ± 0.81SD after 4.64 ± 1.4 years of GH. Conclusion: We offer evidence for Evolving Growth Hormone Deficiency (EGHD) through repeat GST in children with persistent growth slowdown, even with pubertal progression; emphasizing the need for careful longitudinal follow-up to make accurate diagnosis.

Frequency of vitamin D deficiency in children with iron deficiency anaemia and factors associated with vitamin D deficiency.

Objective: To evaluate vitamin D deficiency in children with iron-deficiency anaemia, and to identify the risk factors for such deficiency. METHODS: The cross-sectional study was conducted at the Children's Hospital, Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from October 2021 to March 2022, and comprised children aged 1-5 years who had been diagnosed with iron-deficiency anaemia. Quantitative variables, like age, height, weight, gender, socioeconomic status and sibling status, were controlled by stratification. Data was compared to assess the risk factors of vitamin D deficiency among the subjects. Data was analysed using SPSS 22. RESULTS: Of the 236 children with iron-deficiency anaemia, 159(67.5%) also had vitamin D deficiency; 95(59%) girls and 65(41%) boys. Overall, 104(65.4%) subjects were aged 4-5 years and 55(34.6%) were aged 1-3 years. Vitamin D deficiency had significant association with female gender, older age, height and weight <5th centiles, educated parents, low to middle socioeconomic status, urban residence and higher number of siblings (p<0.05). CONCLUSIONS: The prevalence of vitamin D deficiency among children with iron-deficiency anaemia was found to be high.

Height & income: Labor returns of health in Mexico from 2000 to 2018.

Investment in health has been proposed as a mechanism to promote upward social mobility. Previous analyses have reported inconsistent estimates of the returns to investment in health in Mexico based on different models for different years. We aim to estimate returns for Mexico using data from four time points Adult height and labor income are drawn from the periodical national health and nutrition surveys-a group of relatively standardized surveys-that are representative of individuals living in the country in 2000, 2006, 2012 & 2018. These surveys collect anthropometric measurements and information on individuals' labor income. We estimated Mincerian models separately for men and women using OLS, Heckman, instrumental variables, and Heckman with instrumental variables models. Our results indicate significant and positive returns to health for the four surveys, similar in magnitude across years for women and with variations for men. By 2018, returns to health were about 7.4% per additional centimeter in height for females and 9.3% for males. Investments in health and nutrition during childhood and adolescence that increase health capital-measured as adult height-may promote social mobility in Mexico and similar countries to the extent that these investments differentially increase health capital among the poor.

The importance of assessing the ghosting phenomenon in dynamic footprints when estimating stature - Forensic implications.

In cases where multiple footprints are found at a crime scene, it is unusual that all are static, and some are likely dynamic. Depending on how the footprint was made, we distinguish between dynamic and static footprints. A distinguishing feature that has only recently been associated with dynamic footprints is the fact that dynamic footprints differ from static footprints by the presence of additional markings around the back of the heel and the tops of the toe prints, the so-called ghosting phenomenon. The present study aims to analyse the ghosting phenomenon on dynamic footprints - its occurrence in relation to sex, laterality, and different areas of footprints as well as length features. Additionally, it aims to investigate the assessment of the ghosting phenomenon on dynamic footprints when estimating stature for biological profiling in the forensic field. The study sample comprised of 170 young adults aged 18 - 30 years of both biological sexes. Stature was measured and dynamic footprints were obtained where the ghosting phenomenon was analysed together with length measurements of the same footprint with and without ghosting. In the first and second toes of footprints, the ghosting phenomenon occurred most frequently in both sexes and in the sex-mixed group. Sex differences were not significant in ghosting occurrence on right and left footprints (p > 0.05), except for the area of the left fifth toe (p = 0.045). All the footprints' lengths with ghosting were significantly higher (p < 0.001) than those without ghosting. Statures calculated from footprint length measurements with ghosting predicted stature more accurately than statures calculated from the same footprint length measurements without ghosting. In the case of finding dynamic footprints at crime scenes, it is necessary to correctly identify and evaluate ghosting of the footprint. This comparison can be helpful in interpreting how ghosting should be taken into account when estimating a person's stature.

Y chromosome haplogroups are associated with birth size in Japanese men.

The Y chromosome is classified into haplogroups (A-T) based on a combination of several DNA polymorphisms. Japanese men are mainly classified into haplogroups C, D, and O, which have been further subdivided. The distribution of Y-chromosome haplogroups varies by ethnicity. The phylogenetic age, origin, and migration also differ. I hypothesized that Y chromosome haplogroups may be associated with height and/or weight at birth. An association analysis of height and weight at birth with Y chromosome haplogroups was performed in 288 Japanese men. Men belonging to haplogroup O1b2 were significantly associated with short stature at birth (beta = －1.88, standard error (SE) = 0.55, P = 0.00076), and those belonging to D1a2a-12f2b were significantly associated with increased birth weight (beta = 174, SE = 64, P = 0.0069). Y chromosome haplogroups are associated with physical birth characteristics in modern Japanese men. J. Med. Invest. 71 : 129-133, February, 2024.

Efficacy of Triglyceride Glucose Index-Neck Circumference and Triglyceride Glucose Index-Neck-to-Height Ratio in the Diagnosis of Cardiovascular Diseases and Metabolic Syndrome.

BACKGROUND: A group of characteristics known as metabolic syndrome raises the chance of developing diabetes and cardiovascular disease. Insulin resistance (IR) and obesity are regarded as critical metabolic syndrome pathophysiology. OBJECTIVES: The diagnostic accuracy of IR indicators, triglyceride (TG) glucose index-neck circumference (TyG-NC), and TG glucose index-neck-to-height ratio (TyG-NHtR) to be evaluated for the detection of cardiovascular diseases and metabolic syndrome in nondiabetic individuals. MATERIALS AND METHODS: A cross-sectional study was conducted and passed by the Ethics Committee of the institute. The age should be 18 years or older, and subjects should not have diabetes. Each patient's clinical information was gathered, and lab tests were run. The study was done for a period of 1 year. RESULTS: The study has 100 participants. Around 74% of the group was women. Only 26.5% of the group had an obesity diagnosis. Poor fasting plasma glucose levels were found in 19.4% of the research team. Receiver operating characteristic (ROC)-area under the curve (AUC) testing revealed that all examined IR indices can differentiate individuals with metabolic syndrome from those who are healthy. Our analysis laid out the soaring high area under the ROC curve for TyG index and the low stunted area under the ROC curve for TyG-NC. For obesity, all indices showed appreciable diagnostic efficacy, indicating the maximum achieved area under the ROC curve for TyG index and the minimum recorded metabolic score for IR. The AUC in the case of the metabolic score for IR (METS-IR) male sample population was found to be not statistically compelling. CONCLUSION: The exploration of indirect indices, the proposed ones, namely TyG-NC and TyG-NHtR, emphasized an intricate link between cardiovascular diseases and metabolic syndrome.

Growth charts of Brazilian youngs: 20-years data of 95,000 children and adolescents from "Projeto Esporte Brasil".

This article aims to present growth curves for height, weight, and BMI of 95,000 Brazilian youths aged 6 to 17 years, including the five regions of the country, the Amazon region, and indigenous populations, and compare them with the World Health Organization (WHO) growth references. The final sample consisted of 52,729 boys and 42,731 girls from the "Projeto Esporte Brasil" database. Body mass and height information were used to derive the curves. The generalized additive model for location, scale, and shape was employed. In this study, we present smoothed weight-for-age, height-for-age, and BMI-for-age curves for boys and girls. Differences were observed between the results of the Brazilian curves and the WHO growth references. The developed curves will be valuable for professionals in medicine, public health, nutrition, physical education, and other related fields, regarding the assessment of physical growth in Brazilian children and adolescents and monitoring the nutritional status of this population. Additionally, these curves will facilitate the identification of individuals or subgroups at risk of diseases and delayed growth, with a greater focus on specific country-related factors.

To investigate the pattern of neck injuries and the role of toxicology in cases of hanging and manual/homicidal ligature strangulation in Ireland between 2016 - 2020: A retrospective review and analysis.

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs. OBJECTIVE: To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging. STUDY DESIGN: The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis. RESULTS: Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and increases in a set of physical characteristics of the decedents (weight, BMI and height) with the occurrence of CNFs. Increasing ligature width was not found to increase the likelihood of a CNF occurring, where the Odds Ratio (OR) for this event occurring was 0.9596. Unit increases in body weight and BMI were found to increase the likelihood of the occurrence of a CNF with ORs of 1.0166 and 1.0607 respectively. Increasing height of the decedent yielded an OR = 4.64, demonstrating that CNFs are significantly more likely to occur with increasing height (CI 95 %: 0.2915, 73.9559). CONCLUSIONS: According to the statistical analysis performed for this study, increasing weight, height and BMI are parameters of the decedents which increase the likelihood of the occurrence of CNFs in cases of complete hanging.
