Thigh-hip ratio is significantly associated with all-cause mortality among Japanese community-dwelling men.

Anthropometric evaluation is a simple yet essential indicator of muscle and fat mass when studying life prognosis in aging. This study aimed to investigate the contributions of anthropometric measurements, independent of body mass index, to measures of all-cause mortality. We examined data for 1,704 participants from the 2014 Nomura Cohort Study who attended follow-ups for the subsequent eight years (follow-up rate: 93.0%). Of these, 765 were male (aged 69 ± 11 years) and 939 were female (aged 69 ± 9 years). The Japanese Basic Resident Registry provided data on adjusted relative hazards for all-cause mortality. The data were subjected to a Cox regression analysis, wherein the time variable was age and the risk factors were gender, age, anthropometric index, smoking habits, drinking habits, exercise habits, cardiovascular history, hypertension, lipid levels, diabetes, renal function, and serum uric acid. Of the total number of participants, 158 (9.3%) were confirmed to have died, and of these, 92 were male (12.0% of all male participants) and 66 were female (7.0% of all female participants). The multivariable Cox regression analysis revealed that a smaller thigh-hip ratio predicted eight-year all-cause mortality in male participants, but only baseline body mass index was associated with all-cause mortality in female participants. Thigh-hip ratio is a useful predictor of death in Japanese community-dwelling men.

Invention and Clinical Application of an Oversleeve for Measuring Limb Volume in Postoperative Breast Cancer Patients.

BACKGROUND: Lymphedema is a common complication of breast cancer treatment, affecting 1/5 of breast cancer survivors, but there is no reliable way to detect subclinical lymphedema. OBJECTIVE: The purpose of this study was to determine the feasibility and reliability of using an oversleeve as a postoperative limb volume measurement tool in breast cancer patients. METHODS: Fifty patients were analyzed based on inclusion criteria. A body volume measurement kit was designed based on the drainage volume method and the circumference measurement method. Twenty-two normal healthy people were measured by the drainage volume (LV) and oversleeve measuring limb volume (OMLV) methods, so as to verify the accuracy of OMLV. Twenty-eight patients with lymphedema diagnosed by the circumdiameter measurement (CDM) method were measured with OMLV for comparison. The difference in measurements between OMLV and CDM was compared in 50 patients with early lymphedema diagnosed by the LV method. RESULTS: There was no significant difference between the sleeve method and the drainage volume method in the normal population (P = 0.74). All patients with lymphedema diagnosed by CDM met the diagnostic criteria by the OMLV method. In patients with early lymphedema diagnosed by LV, the diagnostic rate with OMLV was significantly higher than that with CDM (P = 0.008). CONCLUSION: Similar to LV in the diagnosis of lymphedema, OMLV can effectively improve the diagnostic rate of early lymphedema, providing a new option for the diagnosis and treatment of lymphedema.

¿Cómo se pesa al paciente con trastorno de la conducta alimentaria? Revisión del abordaje del peso en los tratamientos / How is the patient with Eating Disorders weighed? Review of weight approach in treatments

Introducción: la excesiva preocupación por el peso y la forma corporal en los Trastornos de la Conducta Alimentaria (TCA) conducen a conductas obsesivas de chequeo y/o evitación corporal. Existe consenso que el peso es un elemento fundamental en el tratamiento de los TCA, sin embargo, en el pesaje conviven enfoques múltiples. Objetivo: describir cómo se aborda el pesaje en el tratamiento de los pacientes con TCA. Materiales y método: el estudio consiste en una revisión de bibliografía, descriptiva. Se incluyeron publicaciones científicas mediante la búsqueda actualizada en base de datos: Scielo, Lilacs y Pubmed, desde 2010 hasta el 2020. Los descriptores de la búsqueda fueron: "pesaje y trastornos alimentarios/desórdenes alimentarios" y "tratamiento, trastornos alimentarios y pesaje". Resultados: de la búsqueda bibliográfica quedaron incluidos 14 artículos internacionales de diseño descriptivo. Los estudios fueron diversos, en estudiantes, atletas, pacientes, grupo control y profesionales, el tamaño muestral fue desde 24 instituciones especializadas en TCA hasta una población de 2287 participantes. Ningún estudio identificó cuál es el profesional encargado de pesar al paciente. El 75% de los artículos que describieron la modalidad de pesaje eligieron pesaje ciego en el comienzo del tratamiento y el resto optó por pesaje abierto, utilizándolo como terapia de exposición. Todos los profesionales modificaron la modalidad de pesaje según el nivel de ansiedad del paciente y el tiempo del tratamiento. Los pacientes prefirieron el pesaje ciego como beneficioso para sus tratamientos. El 90% de los estudios mostraron que los individuos que se autopesaban con mayor frecuencia, iniciaron más tempranamente atracones y conductas compensatorias. Conclusión: los tratamientos basados en evidencia no abordan la modalidad del pesaje de manera consensuada y las recomendaciones varían dentro de las terapias, y a lo largo del tiempo. La utilidad terapéutica del pesaje en los TCA es fundamental para evaluar el riesgo, alertar sobre los cambios en la ingesta alimentaria y para reducir la ansiedad. Sin embargo, es necesario abordarlo con profesionalismo e interdisciplina para disminuir el impacto sobre las conductas perjudiciales para la salud y la psicopatología. Se recomiendan más estudios que ayuden a construir criterios comunes y guías de consenso regional para mejorar el tratamiento de los TCA(AU).

Introduction: excessive concern about weight and body shape in Eating Disorders (ED) lead to obsessive checking and/or body avoidance behaviors. There is consensus that weight is a fundamental element in the treatment of eating disorders, however multiple approaches coexist in weighing. Objectives: to describe how weighing is addressed in the treatment of patients with ED Materials and method: the study consists of a descriptive bibliographic review. Scientific publications were included through the updated database search: Scielo, Lilacs and Pubmed, from 2010 to 2020. Search descriptors were: "body weight and eating disorders/eating disorders" and "treatment, eating disorders and body weight". Results: out of the bibliographic search, 14 international articles of descriptive design were included. The sample groups of the studies were diverse, including students, athletes, patients, control group and professionals, with a sample size of 2287 participants and 24 institutions specialized in eating disorders. No study identified the professional in charge of weighing the patient. 75% of the articles that described the weighing modality chose blind weighing at the beginning of the treatment and the rest opted for open weighing, using it as exposure therapy. All the professionals modified the weighing modality according to the patient's anxiety level and the treatment time. Patients preferred blind weighing as beneficial for their treatment. 90% of the studies showed that individuals who self-weighed more frequently initiated binge eating and compensatory behaviors earlier. Conclusion: evidence-based treatments do not consensually address how the patient is weighed, and the recommendations vary according to therapies and time period. The therapeutic utility of ED weighing is essential to assess risk, alert to changes in food intake, and to reduce anxiety. However, it is necessary to approach it with professionalism and interdiscipline to reduce the impact on behaviors harmful to health and psychopathology. More studies are recommended to help build common criteria and regional consensus guidelines to improve the treatment of ED(AU).

Effects of nutrition education given to persons with multiple sclerosis and their families on diet quality and anthropometric and biochemical measurements / Efeito da educação nutricional dada a pessoas com esclerose múltipla e suas famílias em relação a qualidade da dieta, medidas antropométricas e bioquímicas

ABSTRACT Objective: In this study, it was aimed to investigate the effects of nutrition education given to persons with multiple sclerosis and their families on anthropometric and biochemical measurements and diet quality. Methods: Data from 51 persons with multiple sclerosis were analysed in this intervention study. The study was conducted with 3 groups. The education group consisted of only persons with multiple sclerosis, the family education group consisted of persons with multiple sclerosis and a family member living with them, and the control group consisted of persons with multiple sclerosis who had not received an education. Anthropometric and biochemical measurements and dietary quality assessments were made before (T1) and immediately after education (T2) and also 3 months after education (follow-up, T3). Results: The distribution of family education group diet quality scores showed a significant increase from "poor" to "needs improvement" at T3 compared to T1. The upper middle arm circumference measurements of the female control group were decreased at T2 and T3 [from 29.0 (23-34) cm to 28.0 (22-31) cm and to 27.5 (22-31) cm]. Women in family education group, levels of serum haemoglobin and haematocrit were higher than in control group at T2 and T3. Also, men in family education group, levels of alanine aminotransferase were lower than those in education group at follow up. Levels of total cholesterol and low-density lipoprotein cholesterol in education group were higher than those control group at T1, T2, and T3. Conclusion: This study indicates that nutrition education affects some biochemical and anthropometric measurements in persons with multiple sclerosis. Diet quality improved when receiving education together with families.

ABSTRACT Objective To evaluate the consumption of ultra-processed foods and associate it with anthropometric indicators in adolescents, adults, and the elderly. Methods Cross-sectional, domiciliary, population-based study, comprising adolescents aged 10-19 years, adults aged 20-59 years, and elderly people aged 60 or older, residents of the urban area of the city of Teresina, Piauí. Demographic, socioeconomic, lifestyle, food consumption, and anthropometric data were collected. The analysis of variance test was used along with the Bonferroni post-hoc test and crude and adjusted linear regression with a 95% confidence interval (95% CI). The level of significance adopted was 5%. Results There was no significant association between the consumption of ultra-processed foods and anthropometric variables in adults and the elderly. However, among adolescents, the results showed an inverse association, thus signaling a reduction in anthropometric indicators as the consumption of ultra-processed foods increases. Conclusion There was no association between the consumption of ultra-processed foods and anthropometric indicators in adults and the elderly; however, among adolescents, the results showed an inverse association, which encourages the development of new studies, especially longitudinal ones.

Assessment of peritoneal thickness using CT in relation to dialysis adequacy in peritoneal dialysis patients.

Studies assessing peritoneal thickness by CT in peritoneal dialysis (PD) patients are lacking. In this study, we aimed to investigate the association between peritoneal thickness as measured by CT and dialysis adequacy with peritoneal membrane characteristics in PD patients. Ninety-four PD patients were enrolled. Peritoneal thickness was measured by CT. Patients with and without a decrease in Kt/V of at least 0.3 over time were classified as Group 1 and Group 2, respectively. An increase of 0.1 unit of dialysate/plasma (D/P) creatinine over time were considered significant. The relationship between peritoneal membrane thickness, change in Kt/V, and peritoneal membrane characteristics were investigated. There were 31 (33.0%) patients in Group 1. The duration of PD (86.0 ± 64.1 vs. 59.6 ± 45.2 months, p: 0.023), peritoneal thickness (1.02 ± 0.37 vs. 0.87 ± 0.21 mm, p: 0.015), peritoneal calcification (7 [22.6%] vs. 3 [4.8%] patients, p: 0.013], increased D/P creatinine ratio (14 [45.2%] vs. 14 [22.2%] patients, p: 0.031) and CRP (13.9 ± 11.2 vs. 7.1 ± 4.8 mg/L, p: 0.045) were significantly higher in Group 1, whereas albumin (3.6 ± 0.5 vs. 3.8 ± 0.6 g/dL, p: 0.047) and parathyroid hormone (355.2 ± 260.2 vs. 532.1 ± 332.9 ng/L, p: 0.015) levels were significantly lower. Peritoneal thickness was significantly correlated with duration of PD (r: 0.775, p < 0.001) and CRP (r: 0.282, p: 0.006). Regression analysis showed that peritoneal thickness (Exp (B) [95% CI]: 0.029 [0.003-0.253], p: 0.001) was independent predictor of decreased Kt/V in PD patients. In conclusion, prolonged PD duration and increased peritoneal thickness are associated with a decrease in Kt/V over time. CT may be an alternative and noninvasive method instead of peritoneal biopsy for determining the structural changes of the peritoneal membrane .

Preoperative measurement of the hiatal surface with MDCT: impact on surgical planning.

OBJECTIVE: To evaluate the accuracy and reproducibility of hiatal surface area (HSA) measurement on dedicated multidetector computed tomography (MDCT) acquisition, in patients, previously subjected to laparoscopic sleeve gastrectomy (LSG), and affected by gastroesophageal reflux disease (GERD). Intraoperative HSA measurement was considered the reference standard. METHODS: Fifty-two candidates for laparoscopic hiatal hernia repair were prospectively included in the study. MDCT images were acquired during swallowing of oral iodinated contrast media and during strain. Measurements were performed by nine readers divided into three groups according to their experience. Results were compared with intraoperative measurements by means of Spearman correlation coefficient. Reproducibility was evaluated with intra- and interreader agreement by means of weighted Cohen's kappa and intraclass correlation coefficient (ICC). RESULTS: Significant differences between MDCT and intraoperative HSA measurements were observed for swallowing imaging for less experienced readers (p = 0.037, 0.025, 0.028 and 0.019). No other statistically significant differences were observed (p > 0.05). The correlation between HSA measured intraoperatively and on MDCT was higher for strain imaging compared to swallowing (r = 0.94-0.92 vs 0.94-0.89). The overall reproducibility of MDCT HSA measurement was excellent (ICC of 0.95; 95% CI 0,8993 to 0,9840) independently of reader's experience CONCLUSION: HSA can be accurately measured on MDCT images. This method is reproducible and minimally influenced by reader experience. The preoperative measurement of HSA has potential advantages for surgeons in terms of correct approach to hiatal defects in obese patient.

Comparison of outcomes between gap balancing and measured resection techniques for total knee arthroplasty: A prospective, randomized, controlled trial.

OBJECTIVE: The aim of this study was to compare the effect of Gap Balancing (GB) versus Measured Resection (MR) techniques on the early clinical and radiological results of Total Knee Arthroplasty (TKA). METHODS: In this prospective study, 99 patients (99 knees) who underwent unilateral TKA between March 2018 and January 2019 were randomly allocated to one of two groups: The GP group, TKA with GB technique (19 male, 31 female; mean age = 55.9 ±16.5) and the MR group, TKA with MR technique (19 male, 30 female; mean age = 54.2 ± 18.7). Patients in both groups were comparable in terms of the demographic and clinical data. The angle of cutting block to PCA and Cutting Thickness of the Medial and Lateral Condyle (CTMC, CTLC) were intraoperatively measured. In radiographic analysis, Preoperative Mechanical Femorotibial Angle (Pre-mFTA), Postoperative Mechanical Femorotibial Angle (Post-mFTA), and joint line changes were examined. Femoral component Rotation Angle (FCRA) was also measured by computed tomography. In gait analysis, the spatiotemporal parameters (walking speed, step length, and single support time) and kinematics parameters (flexion angle, extension angle, and transversal rotation) were collected at 12 months postoperatively. Furthermore, Western Ontario and McMaster Universities Arthritis Index (WOMAC) were performed at 12 months after surgery. RESULTS: CTMC and CTLC were both significantly higher in GB group than in the MR group (9.8±2.0 mm vs 8.5 ± 1.2 mm; 7.9 ± 1.8mm vs 6.8 ± 1.4mm; P = 0.001, P = 0.002, respectively). Angle of cutting block to PCA was statistically lower in GB group than in the MR group (1.7 ± 1.5° vs 3.1 ± 0.5 °; P < 0.001). FCRA is greater in the GB group compared to the MR group, but the difference did not reach statistical significance (1.2 ± 2.8 ° vs 0.7 ± 2.0 °; P > 0.05). Although post-mFTA significantly improved compared with pre-mFTA in both groups, no significant difference was observed in the changes of post-mFTA between the two groups (0.9 ± 1.7° vs 0.3 ± 1.8°, P > 0.05). No significant differences were determined between the two groups in spatiotemporal gait parameters including walking speed, step length, and single support time. The sagittal max knee flexion range was significantly larger in the GB group than in the MR group (49.27 ± 5.24 ° vs 45.99 ± 8.21 °, P < 0.05). The flexion range did not reach the level of the control group. There was no significant difference between the two groups in WOMAC at 12 months follow-up (P > 0.05). CONCLUSION: Evidence from this study has revealed GB and MR techniques have both little effect on early clinical results of TKA. Nonetheless, GB technique can provide better knee flexion in the early postoperative gait status compared with MR technique. LEVEL OF EVIDENCE: Level I, Therapeutic Study.

Rethinking Farkas: Updating Cephalic Index Norms in a Large, Diverse Population.

BACKGROUND: Cephalic index, the ratio of head width to length, is one normative indicator used by insurers to derive criteria for plagiocephaly helmet authorization. Current norms were established by a small sample of white children in the 1987 Farkas and Munro data set. This study establishes updated cephalic index values for infants and children in a large, diverse patient population. METHODS: Children aged 0 to 3 months, 3 to 6 months, 9 to 12 months, 2 to 3 years, and 12 to 14 years were recruited at their well-child appointment. Cephalic index was calculated for each age group and compared to previously established norms. RESULTS: Eight hundred seventy patients met inclusion criteria. The means for boys and girls between 0 and 6 months were 83.5 (n = 155, SD 6.01) and 83.5 (n = 191, SD 5.80), respectively. Established means for boys and girls between 0 and 6 months were 74.4 (n = 38, SD 5.2) and 74.3 (n = 49, SD 6.1), respectively. The difference between norms is highly statistically significant (p < 0.0001). For this age range, insurance criteria for a helmet is >83.7 for boys and >82.7 for girls. Using previous norms, 74 boys (44.6 percent) and 104 girls (54.5 percent) would meet criteria for a helmet under current guidelines. CONCLUSIONS: The mean cephalic index of children has changed. The reasons could include diversifying populations in the United States and the introduction of the Back to Sleep campaign. Over 50 percent of children may inappropriately meet criteria for a helmet based on prior norms. Updating norms could change the definition of plagiocephaly for a helmet orthosis.

Do larger reductions yield larger returns? patient-reported outcomes as a function of specimen weight in bilateral reduction mammoplasty.

BACKGROUND: Patients undergoing breast reduction mammoplasty for symptomatic macromastia have a significantly improved quality of life postoperatively. However, there are no data that examine the effect of reduction mammoplasty on quality of life as a function of the weight of tissue removed. Because the process by which insurance providers consider patients' candidacy for this breast reduction mammoplasty is most often based on the proposed weight of tissue to be removed, this gap in our understanding is particularly glaring. We therefore designed a prospective trial with the intent of investigating the correlation between breast reduction specimen weight and postoperative pain and quality of life. METHODS: After obtaining institutional review board (IRB) approval, patients presenting for breast reduction mammoplasty at a single academic medical center between January 2016 and September 2019 were prospectively enrolled in the study. Study participants completed the Numerical Pain Rating Scale (NPRS), the short-form McGill Pain Questionnaire (SF-MPQ), and the BREAST-Q at set time points (preoperatively, 1 week/1 month/3 months/6 months postoperatively). Patients were divided into three cohorts based on breast reduction specimen weights: small (<500 g reduction), intermediate (500-1000 g reduction), and large (>1000 g reduction). The surveys were then analyzed while controlling for demographic factors and complications. RESULTS: A total of 85 women were enrolled in the study and completed pre- and postoperative surveys (small reduction n = 21 (25%), intermediate n = 45 (53%), and large n = 19 (22%)). Regardless of reduction specimen weight, patients reported decreased overall pain and increased satisfaction with their breasts, as well as improved psychosocial, sexual, and physical well-being at each postoperative visit. Preoperative SF-MPQ pain scores were significantly lower in the small specimen weight group compared with either the intermediate or the large group (p = 0.001). Postoperatively, both the intermediate and large groups reported significant improvement in pain at each time point. The small specimen weight group did not report significant pain improvement until 3 months postoperatively. CONCLUSIONS: Patients undergoing breast reduction mammoplasty experience decreased pain and improved quality of life regardless of reduction specimen weight. Improvement in these parameters manifests as early as 1 week postoperatively and maintained at 3 months postoperatively. These data suggest that many patients who are denied coverage for reduction mammoplasty on the basis of low projected reduction specimen weight would derive significant benefit from the procedure.

Measuring the Acetabular Index: An Accurate and Reliable Alternative Method of Measurement.

OBJECTIVE. In children (4 months to 8 years old), radiographic measurements of the acetabular index are the preferred method to assess developmental hip dysplasia. However, the acetabular index has been criticized as having variable reliability owing to difficulty identifying the correct anatomic landmarks. An alternative method of measuring the acetabular index using the ischium is being proposed to avoid the variability of the triradiate cartilage line as a reference point. With the alternative method, the acetabular index is derived by measuring the angle between a line connecting the ischial tuberosi-ties and a line connecting the inferomedial and superolateral edges of the acetabulum. The purpose of this study was to evaluate the accuracy and reliability of this alternative method of measuring the acetabular index compared with the traditional method. MATERIALS AND METHODS. Children 4 months to 8 years old who presented for evaluation of developmental dysplasia of the hip were included. Two physicians, each using both the traditional and the alternative method, measured acetabular indexes on all radiographs. Accuracy was defined as mean absolute error less than 6°. Reliability was calculated by means of intraclass correlation coefficient (ICC). RESULTS. Pelvic radiographs of 40 children (324 hips) were included. The mean age was 23.7 months (range, 4-96 months) and mean acetabular index was 24.2° (range, 8-50°). The alternative method was associated with mean absolute error of 2.50°, which is significantly below the threshold of 6° (t < 0.001). Intrarater reliability for the traditional method was high (ICC, 0.81) and for the alternative method was very high (ICC, 0.92). Interrater reliability for the traditional method was high (ICC, 0.89) and for the alternative method was very high (ICC, 0.91). CONCLUSION. Measuring the acetabular index using the alternative method has very high accuracy and intrarater and interrater reliability.

Importance of measurement methods and demographic characteristics in evaluating ulnar variance: A retrospective comparative study.

OBJECTIVE: This study aimed to compare 2 methods of ulnar variance (UV) measurement (the perpendicular method and the circular method) and to determine whether UV changed based on the demographic characteristics (sex and age). METHODS: UV was measured on bilateral wrist radiographs of 124 patients (62 men, 62 women; mean age=48.5 years; range=18-79 years) who had no history of trauma, congenital wrist anomaly, previous wrist surgery, and wrist osteoarthritis by a single radiologist with 4 years of experience. All measurements were made on standardized radiographic images using 2 methods: the perpendicular method and the circular method. All the patients were then divided into groups based on sex and age, and the study population was determined by selecting a similar number of patients for each sex and age group. RESULTS: The mean UV of the right and left wrists was measured as 0.33 (range=-4.3 to 5.7) mm by the perpendicular method and as 0.034 (range=-5 to 5.7) mm by the circular method. A significant difference was determined between the 2 measurement methods (p<0.001). There was a statistically significant difference between sex and UV values in the left wrist measurements by both methods (p<0.05). A significant correlation was found between the UV and age in both right and left side measurements, indicating a statistically significant difference between the methods (p<0.001). CONCLUSION: The results of our study demonstrated significant differences in the UV measurement between the 2 methods. Furthermore, UV measurement may change based on age and sex. These differences should be considered in the treatment planning of patients with wrist disorders. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

A Review on Penile Length and Girth Issues in Penile Prosthetic Surgery.

PURPOSE OF REVIEW: The goal of this paper is to understand the reasons behind penile length and girth issues after penile prosthesis surgery and review the literature for current strategies employed to decrease these issues. RECENT FINDINGS: Measurement inconsistencies triggering further studies have shown there is a real loss of penile length and girth after prosthesis surgery. There have been varying hypotheses of why this happens, and numerous approaches have been proposed to help combat this in the preoperative, intraoperative, and postoperative settings. Erectile dysfunction prevalence is expected to increase; therefore it is important for urologists to understand the treatment options, including prosthesis surgery. Numerous techniques have been hypothesized and studied in smaller settings in the preoperative, intraoperative, and postoperative settings with regard to prosthetics surgery. However, larger studies are still needed to confirm these findings in order to help to counsel and educate patients preoperatively in addition to employing tactics to help minimize penile shortening.

Overview of tools for the measurement of the orbital volume and their applications to orbital surgery.

There are numerous applications in craniofacial surgery with orbital volume (OV) modification. The careful management of the OV is fundamental to obtain good esthetic and functional results in orbital surgery. With the growth of computer-aided design - computer-aided manufacturing (CAD-CAM) technologies, patient-specific implants and custom-made reconstruction are being used increasingly. The precise measurement of the OV before surgery is becoming a necessity for craniofacial surgeons. There is no consensus on orbital volume measurements (OVMs). Manual segmentation of computed tomography (CT) images is the most used method to determine the OV, but it is time-consuming and very sensitive to operator errors. Here, we describe the various methods of orbital volumetry validated in the literature that can be used by surgeons in preoperative planning of orbital surgery. We also describe the leading software employed for these methods and discuss clinical use (posttraumatic enophthalmos prediction and orbital reconstruction) in which OVMs are important.

Comparing Caliper versus Computed Tomography Measurements of Cranial Dimensions in Children.

OBJECTIVES/HYPOTHESIS: We have found no study assessing the accuracy of caliper cranium measurements compared to computed tomography (CT) measurements of the head. The objective of this study was to assess the reliability of caliper measurements in comparison to CT measurements. STUDY DESIGN: Retrospective chart review. METHODS: This study includes all patients evaluated for head shape abnormality between 2010 and 2019 at a single academic medical center. Eighty-nine patients who had CT head scans were identified, and their caliper measurements of anterior-posterior and transverse head dimensions were documented. RESULTS: There was no statistically significant difference between the CT and caliper measurements. CONCLUSION: Caliper measurements are a simple and reliable way to assess cranial vault proportionality with growth after cranial vault reconstruction.

Identification of the most appropriate existing anthropometric index for home-based obesity screening in children and adolescents.

OBJECTIVES: Home-based self-screening and monitoring for obesity is particularly valuable for the prevention and control of chronic diseases. This study aimed to identify an anthropometric index suitable for home-based obesity screening in children and adolescents. STUDY DESIGN: The design of this study is a cross-sectional study. METHODS: A total of 14,042 students (6-17 years) from the Qibao Community, Minhang District, Shanghai, were studied in 2018. The percentage body fat (PBF), height, weight, waist circumference (WC) and hip circumference were measured. Body mass index (BMI), triponderal mass index (TMI), body adiposity index (BAI), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were calculated. Partial correlation analysis was used to evaluate the relationships between these indices and PBF, and receiver operating characteristic (ROC) curves were used to evaluate their performance for obesity screening. RESULTS: BMI, TMI, WC and WHtR were found to strongly correlate with PBF (r ≥ 0.830, all P < 0.001). The optimal index for obesity screening in children (6-11 years) was BMI (area under the ROC curve [AUC] = 0.980 for boys and 0.981 for girls) and in adolescents (12-17 years) was TIM (AUC = 0.976 for boys and 0.945 for girls); however, the optimal cut-off values for BMI and TMI differed among the subgroups. The ROC curve analysis showed that WHtR had similar cut-off values in each subgroup (0.45 for boys of 6-11 years and 0.43 for the other subgroups), excellent performance in children (AUC>0.90) and good performance in adolescents (AUC = 0.960 for girls and 0.878 for boys). CONCLUSIONS: Owing to its accuracy and stable cut-off value for defining obesity, WHtR should be recommended for home-based obesity screening in children and adolescents.

A cadaveric morphometric analysis of coracoid process with reference to the Latarjet procedure using the "congruent arc technique".

INTRODUCTION: Congruent arc Latarjet procedure involves rotating the coracoid process so that its inferior surface is flush with the glenoid face, owing to their matching radius of curvature (ROC). However, there has been no cadaveric study to actually measure and compare the ROC of coracoid with glenoid, especially in Indian population. MATERIALS AND METHODS: 44 shoulders were dissected in 24 cadavers to measure usable length of coracoid process, width, height, ROC of coracoid and glenoid as well as ulnar length (as proxy of cadaver height). Critical coracoid height and length were estimated based on screw sizes of 2.7 mm, 3.5 mm, 4 mm and 4.5 mm, and pair concordance between height and length calculated. ROC of coracoid and glenoid were compared to measure extent of congruency. RESULTS: The mean usable length of coracoid process, width and height at mid-point were 21.8 mm, 13.7 mm and 8.6 mm, respectively. Out of the different screw sizes, 2.7 mm screws were found safe in 82% shoulders. 24 coracoid-glenoid pairs fulfilled the operational definition (≤ 5 mm) of congruency while rest 20 were seemingly incongruent chiefly due to coracoid variations, with mean ROC difference 4.13 mm (95% CI 1.51-6.74 mm). The ulnar length was significantly smaller in the incongruent ROC group (p = 0.0002). CONCLUSIONS: The available length as well as height of the transferred coracoid must be considered when deciding optimum diameter fixation screws in Latarjet procedure. Owing to smaller anatomic dimensions of coracoid in Indian population, 2.7-mm screws provide the safest fixation option. Also, the ROC of coracoid and glenoid does not match in substantial proportion of the cadavers. Pre-operative planning should include a CT-based assessment of glenoid and coracoid dimensions to decide the technique of Latarjet procedure and the optimum diameter fixation screws required.

Construction and Use of Body Weight Measures from Administrative Data in a Large National Health System: A Systematic Review.

OBJECTIVE: Administrative data are increasingly used in research and evaluation yet lack standardized guidelines for constructing measures using these data. Body weight measures from administrative data serve critical functions of monitoring patient health, evaluating interventions, and informing research. This study aimed to describe the algorithms used by researchers to construct and use weight measures. METHODS: A structured, systematic literature review of studies that constructed body weight measures from the Veterans Health Administration was conducted. Key information regarding time frames and time windows of data collection, measure calculations, data cleaning, treatment of missing and outlier weight values, and validation processes was collected. RESULTS: We identified 39 studies out of 492 nonduplicated records for inclusion. Studies parameterized weight outcomes as change in weight from baseline to follow-up (62%), weight trajectory over time (21%), proportion of participants meeting weight threshold (46%), or multiple methods (28%). Most (90%) reported total time in follow-up and number of time points. Fewer reported time windows (54%), outlier values (51%), missing values (34%), or validation strategies (15%). CONCLUSIONS: A high variability in the operationalization of weight measures was found. Improving methods to construct clinical measures will support transparency and replicability in approaches, guide interpretation of findings, and facilitate comparisons across studies.
