Maternal mid-upper arm circumference as a predictor of low birth weight outcome among newborn deliveries of adolescents in a Tertiary Level Hospital

Background@#Maternal malnutrition is a major cause of low birth weight (LBW) newborn outcome especially among adolescent mothers. It is one of the key drivers of child stunting and initiates the vicious cycle of intergenerational malnutrition. The body mass index prior to pregnancy or at the initial trimester is currently being used to establish the desired weight gain throughout pregnancy. However, Filipino adolescents often delay their first antenatal visit at a later stage of pregnancy. Without a baseline weight, the establishment of appropriate weight gain and nutritional status is often challenging. Mid-upper arm circumference (MUAC) was proven to be a good proxy measure of acute malnutrition, however, there was no global consensus on what MUAC cut-off point to use to identify pregnant adolescents at risk for delivering LBW babies. Finding the optimal cut-off could facilitate early identification and intervention of pregnant adolescents who are nutritionally at risk and could eventually break the cycle of intergenerational malnutrition.@*Objectives@#The study aims to determine the association of maternal MUAC and the birth weight outcomes among newborn deliveries of adolescents in a tertiary hospital for a period of six months and to identify the optimal maternal MUAC cut-off point that can be used to predict low birth weight outcome among newborn deliveries of adolescents in a tertiary hospital. Methods. A cross-sectional study was conducted among adolescents ages 10 to 19 years who delivered babies in a tertiary hospital in the Philippines for a period of six months. Maternal MUAC and LBW outcome were documented, and their association was determined using a logistic regression analysis. To measure diagnostic accuracy, the sensitivity, specificity, and the area under the curve were taken for each MUAC point. A receiver operating characteristic (ROC) curve was used to aid the MUAC cut-off determination.@*Results@#Out of 237 newborn deliveries, 35% were noted with low birth weight while 65% had normal birth weight. Most of the mothers were in their late adolescence at 78%. The crude association for the MUAC cut-offs ≤23.00 cm, ≤23.50 cm, and ≤24.00 cm and LBW showed a significant value of 2.19, 2.25, and 2.39 at 95% CI, respectively. However, it is only the cut-off ≤24.00 cm that showed significant results for adjusted association by the logistic regression analysis. The MUAC cut-off ≤24.00 cm also showed a better trade-off value between the sensitivity and specificity. Furthermore, the optimal maternal MUAC measurement that predicts LBW newborn outcome points to ≤24.00 cm cut-off based on the ROC curve.@*Conclusion@#This study shows that the maternal MUAC is predictive of LBW outcome among adolescent deliveries.A MUAC cut-off of ≤24.00 cm was superior to lower cut-offs studied. The pregnant adolescents might need a higher MUAC cut-off than adults to allow timely intervention and prevention of poor neonatal outcomes. By doing this simple screening test, suspected pregnant adolescents can be easily identified and referred for further confirmatory testing.

Mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion lesion / 中国修复重建外科杂志

OBJECTIVE@#To explore the mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion (PASTA) lesion.@*METHODS@#A clinical data of 39 patients with PASTA lesions, who underwent the arthroscopic "mini incision" transtendon repair and met the selected criteria between May 2017 and April 2021, was retrospectively analyzed. There were 13 males and 26 females, with an average age of 63.7 years (range, 43-76 years). Nine patients underwent trauma history, and no obvious inducement was found in the other 30 patients. The main clinical symptom was shoulder pain with positive hug resistance test. The interval from symptom onset to operation was 3-21 months (mean, 8.3 months). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, American Association of Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention with no complications such as incision infection or nerve injury. All patients were followed up 24-71 months (mean, 46.9 months). The VAS, UCLA, and ASES scores significantly improved at 24 months after operation when compared with preoperative ones ( P<0.05). The ROMs of forward flexion and external rotation of the shoulder joint significantly increased at 3 and 24 months, and further increased at 24 months compared to 3 months, with significant differences ( P<0.05). However, the ROM of abduction of the shoulder joint at 3 months did not significantly improve compared with that before operation ( P>0.05), and it was significantly greater at 24 months than before operation and at 3 months after operation ( P<0.05). At last follow-up, the patients were very satisfied with the effectiveness in 30 cases (76.9%), satisfied in 5 cases (12.8%), and dissatisfied in 4 cases (10.3%). At 6 months after operation, 31 patients underwent reviews of MRI scans, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing, and 3 patients underwent tendon re-tear.@*CONCLUSION@#Arthroscopic "mini incision" transtendon repair in treatment of PASTA lesion could obtain satisfying mid-term effectiveness with low risk of tendon re-tear.

Short- and mid-term effectiveness of unicompartmental knee arthroplasty for post-traumatic arthritis of knee / 中国修复重建外科杂志

OBJECTIVE@#To investigate the short- and mid-term effectiveness of unicompartmental knee arthroplasty (UKA) for post-traumatic arthritis (PTA) of knee.@*METHODS@#The clinical data of 30 patients with PTA of unilateral knee between March 2014 and September 2021 was retrospectively analyzed. There were 14 males and 16 females with an average of 64.5 years (range, 33-81 years). The average body mass index was 26.7 kg/m 2 (range, 19.8-35.6 kg/m 2). The types of injuries that caused PTA included intra-articular fracture in 16 cases, extra-articular fracture in 8 cases, and soft tissue injury in 6 cases. The initial injuries were treated by conservative therapy in 12 cases and by surgical therapy in 18 cases. Ten cases were medial compartment osteoarthritis and 20 cases were lateral compartment osteoarthritis. According to Kellgren-Lawrence staging, there were 19 cases of grade Ⅲ and 11 cases of grade Ⅳ. The operative time, the length of hospital stay, complications, and subjective satisfaction were recorded. The Oxford Knee Function Score (OKS), Hospital for Special Surgery (HSS) score, and knee range of motion (ROM) were used to evaluate knee function. Weight-bearing X-ray films were taken to measure the femoro-tibial angle (FTA) and to assess alignment correction of the lower limb.@*RESULTS@#The operative time ranged from 50 to 95 minutes (mean, 63.7 minutes), the length of hospital stay ranged from 3 to 8 days (mean, 6.9 days). Superficial infection occurred in 2 patients, while the remaining incisions healed by first intention. There was no deep vein thrombosis or neurovascular injury. All patients were followed up 17-109 months (median, 70 months). At last follow-up, OKS score, HSS score, and ROM in 30 cases significantly improved when compared with those before operation (P<0.05). Lower limb alignment was significantly corrected and there was significant difference in FTA of the varus and valgus knees between pre- and post-operation ( P<0.05). The patient satisfaction rate was 86.7% (26/30). Two cases developed contralateral osteoarthritis progression during follow-up. No bearing dislocation, prosthesis loosening or sinking occurred and none required further revision.@*CONCLUSION@#For patients with PTA of knee, UKA can obtain definite short- and mid-term effectiveness with high patient satisfaction.

Mid-term effectiveness of arthroscopic Bankart repair in treatment of recurrent anterior shoulder dislocation / 中国修复重建外科杂志

OBJECTIVE@#To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation.@*METHODS@#The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded.@*RESULTS@#All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation ( P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients' satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level.@*CONCLUSION@#Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.

Concomitant repair of moderate or less tricuspid regurgitation during mitral valve surgery improves early and mid-term prognosis of tricuspid valve and right heart function / 中国胸心血管外科临床杂志

@#Objective    To investigate the effect of concomitant tricuspid valve repair during mitral valve surgery on the early and mid-term prognosis of the tricuspid valve and right heart function in the patients with moderate or less tricuspid regurgitation. Methods    A retrospective study of 461 patients with mitral valve disease requiring cardiac surgery combined with moderate or less tricuspid regurgitation in our hospital from 2011 to 2014 was done. They were 309 males and 152 females with a median age of 53.00 (44.00, 60.00) years. According to whether they received tricuspid valve repair (Kay’s annuloplasty, DeVega’s annuloplasty or annular ring implantation), the patients were divided into a mitral valve surgery only group (a nTAP group, n=289) and a concomitant tricuspid valve repair group (a TAP group, n=172). At the same time, 43 patients whose tricuspid valve annulus diameter was less than 40 mm in the TAP group were analyzed in subgroups. Results    The median follow-up duration was 3.00 years (range from 0.10 to 9.30 years). There was no perioperative death. Three months after surgery, the anteroposterior diameter of the right ventricle in the TAP group was significantly improved compared with that in the nTAP group [–1.00 (–3.00, 1.00) mm vs. 0.00 (–0.20, 2.00) mm, P=0.048]. Three years after surgery, the improvement of right ventricular anteroposterior diameter in the TAP group was still significant compared with the nTAP group [–1.00 (–2.75, 2.00) mm vs. 2.00 (–0.75, 4.00) mm, P=0.014], and the patients in the TAP group were less likely to develop moderate or more tricuspid regurgitation (3.64% vs. 35.64%, P<0.001). Annuloplasty ring implantation was more effective in preventing regurgitation progression (P=0.044). For patients with a tricuspid annulus diameter less than 40 mm, concomitant tricuspid valve repair was still effective in improving the anteroposterior diameter of the right ventricle in the early follow-up (P=0.036). Conclusion     Concomitant tricuspid valve repair for patients with moderate or less tricuspid regurgitation during mitral valve surgery can effectively improve the tricuspid valve and right heart function in the early and mid-term after surgery. Annuloplasty ring implantation is more effective in preventing regurgitation progression. Patients whose tricuspid annulus diameter is less than 40 mm can also benefit from concomitant tricuspid repair.

Short-, mid-, and long-term outcomes of suburethral slings with concomitant pelvic organ prolapse surgeries / Philippine Journal of Obstetrics and Gynecology

Background@#This retrospective cohort study assessed the outcomes of combined surgeries for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) in 31 patients with a follow-up of 7 years.@*Objectives@#The study aimed to determine the success and recurrence rates of POP and SUI while comparing the outcomes, analyzing the predictors for recurrence, and reporting on complications.@*Materials and Methods@#Demographic and clinical profiles were analyzed descriptively using frequency and percentages. Objective SUI cure rate was assessed via office cystometry with a cough stress test, while POP was evaluated using the POP-Q system. Subjective cure rates for both conditions were determined using a symptom severity checklist based on the King's Health Questionnaire. Chi-square tests assessed associations between objective outcome parameters and time elapsed since surgery, and other outcome predictors, with significance set at p < 0.05.@*Results@#The results showed a high objective cure rate of 96% for SUI and subjective cure rates of 96% for both SUI and POP. Long-term symptoms included urine frequency and retention, while mesh erosion occurred in one patient. The objective cure rate for POP was 67.7%, with recurrence in the anterior compartment at the midterm and in various compartments at long term. Vault fixation suggests efficacy in reducing apical prolapse recurrence. The preoperative age was identified as a significant risk factor for POP recurrence. @*Conclusion@#This study supports the durability and efficacy of combined surgeries for SUI and POP, with high patient satisfaction.

Study of the effect of mid-ventricular obstruction on left ventricular systolic function in patients with hypertrophic cardiomyopathy by four-dimensional automatic left ventricular quantitation technology / 中华超声影像学杂志

Objective:To investigate the effect of mid-ventricular obstruction (MVO) on left ventricular systolic function in patients with hypertrophic cardiomyopathy(HCM) by four-dimensional automatic left ventricular quantitation technology(4D Auto LVQ).Methods:Fifty-seven hypertrophic obstructive cardiomyopathy patients were selected from December 2020 to October 2022 in the First Affiliated Hospital of Zhengzhou University. According to the presence of MVO, HCM patients were divided into two groups: HCM 1 group, HCM without MVO ( n=34); HCM 2 group, HCM with MVO ( n=23). In addition, 25 healthy subjects in the same period were selected as the control group. Conventional ultrasound parameters were collected, and 4D Auto LVQ technology was used to obtain the mechanical parameters of left ventricular myocardium, including left ventricular longitudinal strain (GLS), circumferential strain (GCS), area strain (GAS), radial strain (GRS), segmental longitudinal strain (SLS) and area strain (SAS). The differences of these parameters among the three groups were compared. Results:①Compared with the control group, the thickness of the maximum basal segment of interventricular septum, the thickness of the middle segment of the maximum interventricular septum, the thickness of the apical segment of the interventricular septum, the thickness of the left ventricular posterior wall and left atrium diameter were significantly increased. Six-minute walk distance and the left ventricular end-diastolic diameter was decreased in the two groups of HCM(all P<0.05). Left ventricular outflow tract gradients in HCM 1 group was higher than HCM 2 group( P<0.05), but there was no significant difference in left ventricular ejection fraction among the three groups( P>0.05). There was significant difference in the incidence of left ventricular apical aneurysm among the three groups( P<0.05). ②Compared with the control group, the GLS in both HCM groups was lower, and it was lower in the HCM 2 group than in the HCM 1 group(all P<0.05) the GRS and GAS in both HCM groups were lower than in the control group ( P<0.05), and there was no significant difference between the two groups of HCM, and there was no significant difference in GCS among the three groups(all P>0.05). ③Compared with the control group, the SLS of basal segment, middle segment, apical cap, posterior septum, inferior wall and lateral wall in HCM group were significantly lower than those in control group. The SLS of apical segment of posterior septum, anterior septum, anterior wall, posterior wall, inferior wall and apical segment of posterior septum, lateral wall and inferior wall in HCM 2 group were significantly lower than HCM 1 group(all P<0.05), but there was no significant difference in SLS of posterior septum, anterior septum, anterior wall, lateral wall and inferior wall between the two groups(all P>0.05). ④Compared with the control group, the SAS of posterior septal basal segment, middle segment, anterior septal middle segment, anterior wall basal segment, middle segment, apical segment, lateral wall basal segment, middle segment, apical segment, posterior wall basal segment, middle segment, inferior wall basal segment, middle segment and apical cap in HCM groups were significantly lower than the control group(all P<0.05), but there was no significant difference in SAS between the two groups of HCM( P>0.05). Conclusions:4D Auto LVQ can quantitatively evaluate the damage of MVO on the left ventricular systolic function in patients with HCM, especially for the evaluation of local myocardial function damage in the medial segment and apical segment.

Could mid-upper arm circumference be a valid proxy to the body mass index for elderly persons?

Introduction: In elderly persons, due to physiological, anatomical, and functional changes, body mass index (BMI) may not be suitable for the assessment of nutritional status. Mid-upper arm circumference (MUAC) can be a proxy indicator to identify underweight and overweight/obesity among elderly persons. This study aimed to estimate the correlation between MUAC and BMI, and the cutoffs for MUAC using receiver operating characteristic (ROC) analysis. Material and Methods: This survey was carried out in a resettlement colony of Delhi. The participants were residents of the area who were aged 60 years or older, and selected by a simple random sampling technique. The arm span, weight, and MUAC of the participants were measured. The correlation between MUAC and BMI for gender and age group was calculated. The ROC curve was also constructed. Results: A total of 946 eligible participants were enrolled. The correlation between MUAC and BMI was 0.67 (P < 0.001) and 0.76 (P < 0.001) among men and women, respectively. The MUAC cutoff for underweight was <25 cm with a sensitivity of 68.8% and specificity of 84.9%. The area under the curve (AUC) was 0.84 (0.80–0.88). The MUAC cutoff for overweight/obesity was ?27 cm with a sensitivity of 83.9% and specificity of 64.9%, and AUC was 0.78 (0.75–0.82). Conclusion: The MUAC of the participants increased as the BMI of the participants increased. MUAC cutoff was determined using the ROC curve for underweight and overweight/obesity among elderly persons.

Designing of Ready to Eat Convenient Mid - Day Meal for Children (5-10 yrs) and Adolescents (11-19 yrs) of Sri Lanka Based on Nutritional Perspective

The most prevalent malnutrition issues in Sri Lanka are the protein-energy malnutrition (PEM), vitamin A deficiency, and iron deficiency. Childhood and adolescence are the crucial stages of life which mostly susceptible to malnutrition since their major physiological and psychological changes take place. Although a balanced, nutritious diet is essential to them, present socio-economical and higher academic expectations have created a complex environment that often pushes them towards junk foods and unhealthy snacks. The objective of the present study was to develop ready-to-reconstitute convenient mid-day meals in three categories of chicken, fish, and soya, which match to the Sri Lankan local culinary style, with acceptable sensory properties to upgrade the nutritional status of school children (5-10 yrs) and adolescents (11-19 yrs). Those mid-day meals were designed according to the Food-Based Dietary Guidelines (FBDG) of Sri Lanka. The selected ingredients were processed; rice to instant rice, vegetables to dehydrated vegetables, and protein source of chicken, fish, and soya to pre-cooked sterilized curry pouches. The convenient mid-day meal packages were prepared using three portions of instant rice containing 10% of green gram flakes, dehydrated vegetables, and retorted curry mix respectively. Labeling was performed according to the type of curry mix inserted into the package as Chicken, Fish, or Soy mid-day meals. Physicochemical and sensorial properties of meals were evaluated. The caloric value of mid-day meals ranged 575 - 640.82 kcal. The protein content of meals ranged from 25.88 g to 32.68g and there was no significant difference (p<0.05) between protein contents in chicken and fish meals. The fat contents and dietary fiber contents significantly (p<0.05) differed and the highest contents of fat (3.15 g) and dietary fiber (4.40 g) were observed in chicken meal and soy meal respectively. The mineral contents of tested meals significantly differed (p<0.05) and the significant highest Ca, Fe, K, Fe, and P were observed in soya mid–day meals. The highest mean rank scores for all sensory attributes in terms of odor, appearance, texture, taste, and overall acceptability were observed in the chicken mid-day meal. Ready-to-reconstitute mid-day meals in three categories of chicken, fish, and soya, which could match to the Sri Lankan local culinary style, were developed with acceptable sensory properties.

Mortalidade por Insuficiência Cardíaca com Fração de Ejeção Intermediária / Mortality from Heart Failure with Mid-Range Ejection Fraction

Resumo Fundamento A importância prognóstica da classificação 'insuficiência cardíaca (IC) com fração de ejeção (FE) intermediária' permanece incerta. Objetivo Analisar as características clínicas, comorbidades, complicações e mortalidade hospitalar e tardia de pacientes classificados em IC com FE intermediária (ICFEi - FE: 40%-49%) e comparar às daqueles em IC com FE preservada (ICFEp - FE > 50%) e IC com FE reduzida (ICFEr - FE < 40%) na internação por IC descompensada. Métodos Coorte ambispectiva de pacientes internados por IC descompensada em unidade cardiointensiva. Foram avaliadas características clínicas, comorbidades, complicações e mortalidade hospitalar e tardia. Utilizou-se o software R, com significância de 5%, para a realização dos testes qui-quadrado, análises de variância, multivariada de Cox e curva de sobrevida de Kaplan Meier, além de técnicas de machine learning (Elastic Net, árvore de sobrevida). Resultados Foram incluídos 519 indivíduos entre setembro de 2011 e junho de 2019, com média da idade de 74,87±13,56 anos, sendo 57,6% homens. Observou-se frequência de ICFEp, ICFEi e ICFEr de 25,4%, 27% e 47,6%, respectivamente. O infarto prévio foi mais frequente na ICFEi. O tempo médio de seguimento foi 2,94±2,55 anos, sem diferença estatística da mortalidade entre os grupos (53,8%, 52,1% e 57,9%). Na curva de sobrevida, não houve diferença entre os grupos ICFEp e ICFEi, nem entre ICFEp e ICFEr, mas houve entre os grupos ICFEi e ICFEr. Idade maior que 77 anos, IC prévia, história de readmissão, demência e necessidade de vasopressores foram associadas com maior mortalidade tardia na árvore de sobrevida. Conclusão A FE não foi selecionada como variável associada a mortalidade nos pacientes com IC descompensada.

Abstract Background The prognostic importance of the classification 'heart failure (HF) with mid-range ejection fraction (EF)' remains uncertain. Objective To analyze the clinical characteristics, comorbidities, complications, and in-hospital and late mortality of patients classified as having HF with mid-range EF (HFmrEF - EF: 40%-49%), and to compare them to those of patients with HF with preserved EF (HFpEF - EF > 50%) and with HF with reduced EF (HFrEF - EF < 40%) on admission for decompensated HF. Methods Ambispective cohort of patients admitted to the cardiac intensive care unit due to decompensated HF. Clinical characteristics, comorbidities, complications, and in-hospital and late mortality were assessed. The software R was used, with a 5% significance, for the tests chi-square, analysis of variance, Cox multivariate, and Kaplan-Meier survival curve, in addition to machine-learning techniques (Elastic Net and survival tree). Results 519 individuals were included between September 2011 and June 2019 (mean age, 74.87 ± 13.56 years; 57.6% were men). The frequencies of HFpEF, HFmrEF and HFrEF were 25.4%, 27% and 47.6%, respectively. Previous infarction was more frequent in HFmrEF. The mean follow-up time was 2.94 ± 2.55 years, with no statistical difference in mortality between the groups (53.8%, 52.1%, 57.9%). In the survival curve, there was difference between neither the HFpEF and HFmrEF groups, nor the HFpEF and HFrEF groups, but between the HFmrEF and HFrEF groups. Age over 77 years, previous HF, history of readmission, dementia and need for vasopressors were associated with higher late mortality in the survival tree. Conclusion The EF was not selected as a variable associated with mortality in patients with decompensated HF.

Morphometry and Sexual Dimorphism of the Human Clavicle in South Indian Population

Background: In forensic anthropology, determining an individual’s sex is the fundamental criteria of identification, but this is a tough task that gets considerably more difficult when only a single bone, such as the clavicle, is available. In physical anthropology, determining the sex of a deceased individual is a fundamental prerequisite. Physical anthropologists have gotten more concerned about the difficulties of human identity in recent years. Traditional techniques of sexing bone are subjective and ineffective when absolute sexing precision is desired, hence this study. Methods: Measurement of clavicular length and circumference using an Osteometric board or sliding and Vernier Callipers product from 1128 dry clavicles of unknown sex and age procured from various medical institutions and departments of anthropology in south India. Length, inner angle, outer angle, the sum of angles, inner segment, middle segment, outside segment, width at the inner end at an inner angle, least width at conoid tubercle, at the outer end, and mid circumference have all been measured. Results and Discussion: The male mid-shaft circumference is 38.0±0.5mm on the right side and 36.5±0.5mm on the left side, whereas the female mid-shaft circumference is 31.4±0.3mm on the right side and 31.4±0.6mm on the left side. The length of the left clavicle is greater than the length of the right collarbone. The curvature of the right collarbone is higher than that of the left, resulting in a shorter right bone than the left. The clavicle of males has a higher mean across all parameters than females. Male clavicle length is more than female clavicle length, midshaft circumference is less in females than males, and breadth at an inner angle is shorter in females than men, all of which are statistically significant. The Mid-shaft Circumference as a sex-determination metric is statistically significant in differentiating the clavicle’s sex. This delivers a better result than clavicle weight since clavicle weight fluctuates with age and the health state of the individual. Male clavicles have a larger Midshaft Circumference than female clavicles.

To Blame or Not? Modulating Third-Party Punishment with the Framing Effect / 神经科学通报·英文版

People as third-party observers, without direct self-interest, may punish norm violators to maintain social norms. However, third-party judgment and the follow-up punishment might be susceptible to the way we frame (i.e., verbally describe) a norm violation. We conducted a behavioral and a neuroimaging experiment to investigate the above phenomenon, which we call the "third-party framing effect". In these experiments, participants observed an anonymous perpetrator deciding whether to keep her/his economic benefit while exposing a victim to a risk of physical pain (described as "harming others" in one condition and "not helping others" in the other condition), then they had a chance to punish that perpetrator at their own cost. Our results showed that the participants were more willing to execute third-party punishment under the harm frame compared to the help frame, manifesting a framing effect. Self-reported anger toward perpetrators mediated the relationship between empathy toward victims and the framing effect. Meanwhile, activation of the insula mediated the relationship between mid-cingulate cortex activation and the framing effect; the functional connectivity between these regions significantly predicted the size of the framing effect. These findings shed light on the psychological and neural mechanisms of the third-party framing effect.

Repair of soft tissue defect of mid-and forefoot with anterolateral wide pedicled double dynamic flap of calf / 中华显微外科杂志

Objective:To investigate the effects of anterolateral wide pedicled double dynamic flap of the calf in repair of soft tissue defects of mid-and forefoot.Methods:From September 2015 to Septemler 2020, 15 cases with severe soft tissue defects of mid-and forefoot were repaired with the anterolateral wide pedicled double dynamic flap of the calf. There were 11 males and 4 females with an average age of 37(range, 22-53)years old. Of the 15 cases, the defects were caused by traffic accident in 6 cases and objects smash in 9 cases. Three cases were simple soft tissue defect, and 12 cases combined with fracture or dislocation and bone defect. The size of soft tissue defects ranged from 4 cm×5 cm to 7 cm×12 cm. All wounds of donor sites were repaired by skin grafting. All patients entered follow-ups at the outpatient clinic or through WeChat. The appearance of flaps and limb recovery were recorded after surgery.Results:All cases followed-up for 6-24 (mean, 16) months. Two days after surgery, 1 case had flap swelling and cyanosis, which was improved after pedicle suture removal and surface bloodletting. The pedicle of the flap was slightly bloated in 4 cases, and the texture and appearance were good in 11 cases. The ankle function of all cases recovered satisfactorily. The ranges of ankle motion were 15°-20° for dorsiflexion and 30°-40° for plantar flexion. The donor site healed well and all the skin grafts survived.Conclusion:The anterolateral wide pedicled double dynamic flap of the calf is one of the ideal flaps for repairing the soft tissue defects of the mid-and forefoot with reliable blood supply, sufficient venous return, simple operation and no require a vascular anastomosis.

Clinical observation of peroral endoscopic myotomy for mid-esophageal diverticulum in 7 cases / 中华消化内镜杂志

To investigate the effectiveness and safety of diverticular peroral endoscopic myotomy (D-POEM) for mid-esophageal diverticulum. Data of consecutive patients in the prospective database with mid-esophageal diverticulum who received D-POEM in West China Hospital, Sichuan University between April 2014 to September 2019 were collected. The modified Eckardt scoring system for mid-esophageal diverticulum was used to evaluate the severity of diverticular symptoms. The effectiveness and safety of D-POEM were evaluated in terms of clinical success, technical success, complications and recurrence. A total of 7 patients with mid-esophageal diverticulum were included. Clinical and technical success was achieved in all patients with operation time of 16-70 minutes. No serious complications (2 cases with minor complications) or recurrence occurred. The follow-up time was 2-16 months. The median modified Eckardt score decreased from 3 points before operation to 0 points after operation. It is preliminarily believed that D-POEM ensures a complete septotomy between normal esophageal lumen and esophageal diverticulum. It is a safe and effective technique for mid-esophageal diverticulum. The modified Eckardt scoring system is suitable for symptom evaluation before and after treatment of mid-esophageal diverticulum.

Safety and prognosis analysis of transanal total mesorectal excision versus laparoscopic mesorectal excision for mid-low rectal cancer / 中华胃肠外科杂志

Objective: To compare the short-term and long-term outcomes between transanal total mesorectal excision (taTME) and laparoscopic total mesorectal excision (laTME) for mid-to-low rectal cancer and to evaluate the learning curve of taTME. Methods: This study was a retrospective cohort study. Firstly, consecutive patients undergoing total mesorectal excision who were registered in the prospective established database of Division of Colorectal Diseases, Department of General Surgery, Peking Union Medical College Hospital during July 2014 to June 2020 were recruited. The enrolled patients were divided into taTME and laTME group. The demographic data, clinical characteristics, neoadjuvant treatment, intraoperative and postoperative complications, pathological results and follow-up data were extracted from the database. The primary endpoint was the incidence of anastomotic leakage and the secondary endpoints included the 3-year disease-free survival (DFS) and the 3-year local recurrence rate. Independent t-test for comparison between groups of normally distributed measures; skewed measures were expressed as M (range). Categorical variables were expressed as examples (%) and the χ(2) or Fisher exact probability was used for comparison between groups. When comparing the incidence of anastomotic leakage, 5 variables including sex, BMI, clinical stage evaluated by MRI, distance from tumor to anal margin evaluated by MRI, and whether receiving neoadjuvant treatment were balanced by propensity score matching (PSM) to adjust confounders. Kaplan-Meier curve and Log-rank test were used to compare the DFS of two groups. Cox proportional hazard model was used to analyze and determine the independent risk factors affecting the DFS of patients with mid-low rectal cancer. Secondly, the data of consecutive patients undergoing taTME performed by the same surgical team (the trananal procedures were performed by the same main surgeon) from February 2017 to March 2021 were separately extracted and analyzed. The multidimensional cumulative sum (CUSUM) control chart was used to draw the learning curve of taTME. The outcomes of 'mature' taTME cases through learning curve were compared with laTME cases and the independent risk factors of DFS of 'mature' cases were also analyzed. Results: Two hundred and forty-three patients were eventually enrolled, including 182 undergoing laTME and 61 undergoing taTME. After PSM, both fifty-two patients were in laTME group and taTME group respectively, and patients of these two groups had comparable characteristics in sex, age, BMI, clinical tumor stage, distance from tumor to anal margin by MRI, mesorectal fasciae (MRF) and extramural vascular invasion (EMVI) by MRI and proportion of receiving neoadjuvant treatment. After PSM, as compared to laTME group, taTME group showed significantly longer operation time [(198.4±58.3) min vs. (147.9±47.3) min, t=-4.321, P<0.001], higher ratio of blood loss >100 ml during surgery [17.3% (9/52) vs. 0, P=0.003], higher incidence of anastomotic leakage [26.9% (14/52) vs. 3.8% (2/52), χ(2)=10.636, P=0.001] and higher morbidity of overall postoperative complications [55.8%(29/52) vs. 19.2% (10/52), χ(2)=14.810, P<0.001]. Total harvested lymph nodes and circumferential resection margin involvement were comparable between two groups (both P>0.05). The median follow-up for the whole group was 24 (1 to 72) months, with 4 cases lost, giving a follow-up rate of 98.4% (239/243). The laTME group had significantly better 3-year DFS than taTME group (83.9% vs. 73.0%, P=0.019), while the 3-year local recurrence rate was similar in two groups (1.7% vs. 3.6%, P=0.420). Multivariate analysis showed that and taTME surgery (HR=3.202, 95%CI: 1.592-6.441, P=0.001) the postoperative pathological staging of UICC stage II (HR=13.862, 95%CI:1.810-106.150, P=0.011), stage III (HR=8.705, 95%CI: 1.104-68.670, P=0.040) were independent risk factors for 3-year DFS. Analysis of taTME learning curve revealed that surgeons would cross over the learning stage after performing 28 cases. To compare the two groups excluding the cases within the learning stage, there was no significant difference between two groups after PSM no matter in the incidence of anastomotic leakage [taTME: 6.7%(1/15); laTME: 5.3% (2/38), P=1.000] or overall complications [taTME: 33.3%(5/15), laTME: 26.3%(10/38), P=0.737]. The taTME was still an independent risk factor of 3-year DFS only analyzing patients crossing over the learning stage (HR=5.351, 95%CI:1.666-17.192, P=0.005), and whether crossing over the learning stage was not the independent risk factor of 3-year DFS for mid-low rectal cancer patients undergoing taTME (HR=0.954, 95%CI:0.227-4.017, P=0.949). Conclusions: Compared with conventional laTME, taTME may increase the risk of anastomotic leakage and compromise the oncological outcomes. Performing taTME within the learning stage may significantly increase the risk of postoperative anastomotic leakage.

Chinese expert consensus on protective ostomy for mid-low rectal cancer (version 2022) / 中华胃肠外科杂志

The rate of sphincter-preserving surgery for mid-low rectal cancer is increasing, but anastomotic leakage remains to be one of the common serious complications after operation. How to reduce the morbility and mortality of anastomotic leakage is always a hot and difficult point in colorectal surgery. Protective ostomy is a common method to deal with the above problems in clinical practice. However, some problems such as inappropriate stoma and stoma-related complications etc. become the current clinical challenges. The purpose of this consensus focusing on indication of ostomy, clinical value, ostomy skills, prevention of stoma complications, reversion of stoma and stoma nursing aims to provide guidance for the clinical practice of protective ostomy in the operation of mid-low rectal cancer in China.

Prognostic value of mid-regional proadrenomedullin in low-risk patients with sepsis / 中华急诊医学杂志

Objective:To investigate the predictive value of mid-regional proadrenomedullin (MR-proADM) on poor prognosis of low-risk patients with sepsis.Methods:This was a prospective cohort study. Patients with sepsis admitted to the Emergency Intensive Care Unit of China Rehabilitation Research Center from December 2018 to December 2020 were included in this study. The patients were divided into the low-risk group (SOFA≤7) and medium-high-risk group (SOFA>7) according to the sequential organ failure assessment (SOFA) score, and the clinical characteristics of the two groups were compared. Proportional hazards regression model (COX regression model) was used to investigate the risk factors of 28-day mortality in the low-risk and medium-high-risk group. The predictive ability of MR-proADM, C-reactive protein (CRP), lactic acid (Lac), interleukin-6 (IL-6), SOFA score, and acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score for the prognosis in each group was evaluated by receiver operating characteristic (ROC) curve. The outcomes of patients with different concentration of MR-proADM in the low-risk group were compared.Results:Totally 205 patients with sepsis were included, and the 28-day mortality was 41.0% (84/205). There were significant differences in the number of organ dysfunction, acute kidney injury, use of vasoactive drugs, Lac, IL-6, SOFA score and APACHEⅡ score between the two groups ( P<0.05). Cox regression model showed that age, MR-proADM, mechanical ventilation, IL-6 and APACHEⅡ score were the risk factors of 28-day death in the low-risk group, while MR-proADM, Lac, SOFA score and APACHEⅡ score were the risk factors of 28-day mortality in the medium-high-risk group. In each group, MR-proADM had a good predictive ability for the prognosis of patients with sepsis ( P<0.001). Especially in low-risk patients with sepsis, the predictive ability of MR-proADM was better than other indicators. Kaplan-Meier survival curve suggested that the patients with MR-proADM >2.53 nmol/L had worse prognosis than those with MR-proADM ≤2.53 nmol/L, and the difference was statistically significant ( P<0.001). In the low-risk group, the mortality of patients increased from 7.8% to 58.2% if MR-proADM >2.53 nmol/L. Conclusions:MR-proADM is a risk factor for 28-day mortality in patients with sepsis, and MR-proADM can early identify the poor prognosis of low-risk patients with sepsis.
