Abstract Background There is a controversy about the management of patients with a thoracolumbar burst fracture. Despite the success of the conservative treatment in most of the cases, some patients failed the conservative treatment. The present study aimed to evaluate risk factors for the need for surgery during the follow-up period in these patients. Methods We retrospectively evaluated 67 patients with a traumatic thoracolumbar burst fracture who managed conservatively at our center between May 2014 and May 2019. Suggested variables as potential risk factors for the failure of conservative treatment including age, gender, body mass index (BMI), smoking, diabetes, vertebral body compression rate (VBCR), percentage of anterior height compression (PAHC), Cobb angle, interpedicular distance (IPD), canal compromise, and pain intensity as visual analog scale (VAS) were compared between patients with successful conservative treatment and those with failure of non-operative management. Results There were 41 males (61.2%) and 26 females (38.8%) with the mean follow-up time of 15.52 ± 5.30 months. Overall, 51 patients (76.1%) successfully completed conservative treatment. However, 16 cases (23.9%) failed the non-operative management. According to the binary logistic regression analysis, only age (risk ratio [RR], 2.21; 95% confidence interval [95%], 1.78–2.64; P = 0.019) and IPD (RR 1.97; 95% CI 1.61–2.33; P = 0.005) were the independent risk factors for the failure of the non-operative management. Conclusions Our results showed that older patients and those with greater interpedicular distance are at a higher risk for failure of the conservative treatment. As a result, a closer follow-up should be considered for them.

Abstract Background Hip fractures are typical fractures in geriatric patients and are associated with a high risk of postoperative complications and extended length of stay (LOS) compared with other osteoporotic fractures, particularly among patients over age 90. We aimed to identify the risk factors for extended LOS (more than 14 days) in patients older than 90 years. Methods A single-centre retrospective cohort study was performed in 50 patients (over age 90) who experienced hip fracture between June 1, 2013, and August 31, 2017. Their medical records were retrospectively reviewed from the hospital’s electronic database. The baseline characteristics of the patients, intraoperative data and postoperative complications were collected for the assessment of potential risk factors. Univariate analysis and multivariate binary logistic regression analysis were performed to determine potential risk factors for extended LOS. Results The age of the patients in the cohort ranged from 90 to 101 years, and the analysis demonstrated that 70% (n = 35) of the patients experienced a complicated course of treatment with an in-hospital mortality rate of 4% (n = 2). The most common complication was the occurrence of postoperative pneumonia (38%). The median duration of hospital stay was 18 (IQR 11, 21) days. Multivariate binary logistic regression analysis showed that a LOS of more than 14 days was significantly associated with a lower mean diastolic blood pressure during surgery [odds ratio (OR) =0.86, 95% confidence interval (CI)=0.76-0.98, P = 0.018] and the occurrence of postoperative pneumonia (OR=8.95, 95% CI=1.45-55.3, P = 0.018). The occurrence of postoperative pneumonia was significantly associated with the neutrophil-to-lymphocyte ratio (NLR) at admission (D0) [odds ratio (OR) =1.20, 95% confidence interval (CI)=1.02-1.41, P = 0.029]. Neither the LOS nor postoperative pneumonia was found to be associated with the anaesthesia technique. Conclusions A lower mean diastolic blood pressure during surgery and the occurrence of postoperative pneumonia may extend the LOS in patients aged 90 years and over who undergo hip fracture surgery. The use of regional anaesthesia was not associated with a shorter LOS.

Background: Fractures of the middle and distal diaphysis of the forearm are common in children. Conservative treatment is effective in this regard. Some studies have discussed the risk factors and predictive indicators of re-displacement; however, the objects of the study are all fixed with tubular plaster or double sugar splint. Objectives: This study was performed to determine the risk factors of re-displacement after closed reduction and double splint plaster fixation of unstable pediatric fractures of the middle and distal diaphysis of the forearm. Methods: This retrospective study was conducted on 57 patients undergoing closed reduction and plaster fixation after unstable diaphyseal fractures of the middle and distal forearm in Wuxi Children's Hospital of Nanjing Medical University within May 2014 to May 2020. A total of 35 male and 22 female subjects aged 6 - 9 years (average: 7.3 years) participated in this study. They were followed up for more than 6 weeks after fracture healing. According to whether experiencing a secondary displacement within 2 weeks after the fracture, the subjects were divided into two groups, namely displacement, and non-displacement. Gender, age, double fracture, reduction quality, and plaster fixation type were analyzed as relevant, effective factors. Results: All 57 patients were followed up, and all fractures reached clinical healing standards at the last follow-up. Moreover, 20 and 37 cases were in the shift and non-shift groups, respectively. No statistically significant difference was reported in gender (c2 = 0.168; P = 0.780), age (t = 1.003; P = 0.217), double fracture (c2 = 0.021; P = 1), and plaster fixation type (c2 = 0.416; P = 0.699) between the two groups. The reduction quality (c2 = 7.480; P = 0.025) showed a statistically significant difference. Binary logistic regression analysis showed that reduction quality was a risk factor for fracture relocation providing a predictive value. Conclusions: Good reduction quality can reduce the risk of fracture displacement.

Background and objective To determine the risk factors for recurrence after endovascular embolization of posterior communicating artery aneurysms (PcomA). Methods We retrospectively analyzed a cohort of 163 patients harboring 172 PocmAs who were treated with endovascular embolization from January 2019 to December 2020. The patients were divided into recurrence and stable groups depending on outcome. Univariate and logistic regression analyses were performed to determine the potential risk factors of recurrence during follow-up. Results Of the total 163 patients harboring 172 aneurysms, 107 were treated with simple coil occlusion and 65 were treated with stent-assisted coil embolization. There were significant differences in aneurysm sizes and use of non-stent-assisted coil embolizations between the groups (P < 0.05). The incidence of saccular aneurysm and Raymond grade were significantly higher in the recurrent group than in the stable group (P < 0.01). After variable selection, Raymond grade, aneurysm size, saccular aneurysm and non-stent-assisted coil embolization were included in further analysis. Binary logistic regression analysis revealed significant associations with non-stent-assisted coil embolization (P = 0.007), packing density (P < 0.001) and Raymond grades II (P < 0.001) and III (P = 0.002). Conclusion Non-stent-assisted coil embolization, as well as packing density and Raymond grades II grade III are associated with recurrence after endovascular treatment of PcomA.

Abstract Background Childhood under-nutrition is far-reaching in low and middle-income nations. Undernutrition is one of the major open wellbeing concerns among newborn children and youthful children in Ethiopia. The present study aimed to explore the potential risk factors of undernutrition among children under 5 years of age in Somali Region, Ethiopia. Methods The data for this study was extricated from the Ethiopian Demographic and Health Survey (EDHS) 2016. The data collected from 1339 children born 5 years before was considered within the analysis. A multivariable binary logistic regression analysis was utilized at a 5% level of significance to decide the individual and community-level variables related to childhood malnutrition. Results The prevalence of stunting, underweight and wasting were 27.4, 28.7 and 22.7%, respectively. About 16.1% of children were both stunted and underweight; the extent of both being underweight and wasted was 11.7%, the prevalence of both stunted and wasted children was 5.5%, and all three malnutrition conditions were 4.7% children. Among the variables considered in this study, age of the child in months, type of birth, anemia level, size of child at birth, sex of the child, mothers’ BMI and sources of drinking water were significantly related to stunting, underweight and wasting in Somali Region. Conclusions The prevalence of stunting, underweight and wasting was relatively high. Undernutrition is one of the major open wellbeing concerns among children in Somali region. The impact of these variables ought to be considered to develop strategies for decreasing the lack of healthy sustenance due to undernutrition in the study areas. Hence, intercession should be centered on making strides for the under-nutrition determinant variables of the children to be solid, to improve the child’s wholesome status, and decrease child mortality quickly.

ObjectiveTo investigate the risk factors of neutralizing antibody (NAB)–induced complete secondary treatment failure (cSTF) during long-term botulinum neurotoxin (BoNT) treatment in various neurologic indications.MethodsThis monocenter retrospective cohort study analyzed the data of 471 patients started on BoNT therapy between 1995 and 2015. Blood samples of 173 patients were investigated for NABs using the mouse hemidiaphragm test (93 with suspected therapy failure, 80 prospective study participants). The frequency of NAB-cSTF was assessed for various indications: hemifacial spasm, blepharospasm, cervical dystonia, other dystonia, and spasticity. A priori defined potential risk factors for NAB-cSTF were evaluated, and a stepwise binary logistic regression analysis was performed to identify independent risk factors.ResultsTreatment duration was 9.8 ± 6.2 years (range, 0.5–30 years; adherence, 70.6%) and number of treatment cycles 31.2 ± 22.5 (3–112). Twenty-eight of 471 patients (5.9%) had NAB-cSTF at earliest after 3 and at latest after 103 treatment cycles. None of the 49 patients treated exclusively with incobotulinumtoxinA over 8.4 ± 4.2 (1–14) years developed NAB-cSTF. Independent risk factors for NAB-cSTF were high BoNT dose per treatment, switching between onabotulinumtoxinA and other BoNT formulations (except for switching to incobotulinumtoxinA), and treatment of neck muscles.ConclusionsWe present a follow-up study with the longest duration to date on the incidence of NAB-cSTF in patients treated with various BoNT formulations, including incobotulinumtoxinA. Whereas the overall risk of NAB-cSTF is low across indications and BoNT formulations, our findings underpin the recommendations to use the lowest possible dose particularly in cervical dystonia, and to avoid unnecessary switching between different formulations.

Objective This study aimed to explore the prevalence of hyperuricemia among the general adult population in Shenzhen and to determine the risk factors of hyperuricemia. Methods A total of 9337 cases who underwent physical examination in The Seventh Affiliated Hospital of Sun Yat-Sen University in 2020 were enrolled in this study. The binary logistic regression analysis was performed to determine potential risk factors of hyperuricemia. Result The overall prevalence rate of hyperuricemia in the studied population was 40.5% (3783/9337). Subgroup analysis showed that the prevalence of males was 52.8% (3046/5769) and the prevalence of females was 20.7% (737/3568). Moreover, among different age groups (≤29 years old, 30-39 years old, 40-49 years old, 50-59 years old, and ≥60 years old), the prevalence rate of males was significantly higher than that of females (P<0.05). To further determine the relationship between the body mass index (BMI) and hyperuricemia, the population with normal BMI was set as the control group. After controlling for gender and age, the prevalence rate of hyperuricemia in the overweight population increased by 1.799 times; and the prevalence rate in the obese and very obese population increased by 3.283 times and 3.830 times, respectively. Conclusion The data presented in this study demonstrated that the prevalence rate of hyperuricemia is high in Shenzhen, espeially in males. Moreover, the level of BMI is significantly linked to the prevalence of hyperuricemia. Therefore, early interventions should be carried out to address the high prevalence of hyperuricemia in male and obese populations.

Abstract Background: Risk factors and clinical outcome associated with distal adding on in Lenke 2AR adolescent idiopathic scoliosis (AIS) are not fully elucidated.Methods: Radiographic data of Lenke 2AR AIS patients treated by posterior pedicle screws in a single institution were retrospectively analyzed. Patients who developed distal adding on were compared with patients who did not. Clinical assessment were carried out by SF-36 and SRS-22 questionnaire. Risk factors of distal adding on were explored by binary logistic regression analysis.Results: A total of 88 patients completed an average of 2.9 (2-12.9) years of follow-up were included. 18 (20.5%) patients met the criterion of distal adding on while the rest of 70 cases did not at follow up.Clinical parameters were comparable before surgery and became lower at follow up in adding on group in dimensions of vitality (63.1±11.4Vs.67.5±11.8,P=0.026), mental health (73.9±9.2Vs.77.8±10.2,P=0.039), self-image (3.9±0.3Vs.4.2±0.3,P=0.021) and satisfaction (4.0±0.3Vs.4.5±0.4,P=0.035). The proportion of selection lowest instrumented vertebra (LIV) higher than last touching vertebra(LTV) was significantly higher in adding on group. (6/18vs 4/70, P=0.004) Binary logistic regression analysis revealed that preoperative main thoracic curve magnitude (OR=1.118,P=0.041), preoperative lumbar lordosis (OR=1.091,P=0.029), and the gap between LIV and LTV(OR=6.123,P=0.043) were independent risk factors associated with adding on.Conclusions: In Lenke 2AR AIS cases, the selection of LIV higher than LTV is closely correlated with the development of adding-on. Patients with minor main thoracic curve and lumbar lordosis are more likely to develop distal adding on. Adding on may cause discontent of patients .

Abstract Background Screening for latent tuberculosis infection (LTBI) among migrant population has become a critical issue for many low tuberculosis (TB) burden countries. Evidence regarding effectiveness of LTBI programs are limited, however, partly because of paucity of national data on treatment outcomes for LTBI. In Japan, notification of LTBI is mandatory, and its treatment outcome is reported as part of Japan’s national TB surveillance system. We thus conducted a detailed analysis of LTBI among foreign-born persons, to update the epidemiological trend of newly notified LTBI between 2007 and 2018, and to examine the treatment regimen and outcome of those notified in 2016 and 2017, focusing specifically on the potential risk factors for lost to follow-up. Methods We extracted and analyzed the data of newly notified LTBI patients from the Japan Tuberculosis Surveillance System to examine the overall trend of notification and by age groups and modes of detection between 2007 and 2018, and the cohort data for treatment regimen and outcomes of foreign-born persons notified with LTBI in 2016 and 2017. Trends and proportions were summarized descriptively, and logistic regression analysis was conducted to identify potential risk factors for lost to follow-up. Comparisons were made with the Japan-born patients where appropriate, using chi-squared tests. Results Both the number and proportion of LTBI among foreign-born persons have been constantly increasing, reaching 963 cases in 2018. Cohort analysis of the surveillance data indicated that the proportion of those on shorter regimen was higher among the foreign- than Japan-born patients (5.5% vs. 1.8%, p < 0.001). The proportion of those who have been lost to follow-up and transferred outside of Japan combined was higher among the foreign- than Japan-born patients (12.0% vs, 8.2%, p < 0.001). Risk factors for lost to follow-up were being employed on a temporal basis, and job status unknown (adjusted odds ratios 3.11 and 4.09, 95% confidence intervals 1.34–7.26 and 1.60–10.48, respectively). Conclusions Migrant population face greater risk of interrupting LTBI treatment, and interventions to improve adherence are a critical component of programmatic management of LTBI. Further studies are needed to explore the cultural and socioeconomic situation in which foreign-born persons undergo LTBI treatment in Japan.

Background and objectives: For the last three decades, non-operative management (NOM) has been the standard in the treatment of clinically stable patients with blunt spleen injury, with a success rate of up to 95%. However, there are no prospective issues in the literature dealing with the incidence and type of splenic complications after NOM. Materials and methods: This study analyzed 76 pediatric patients, up to the age of 18, with blunt splenic injury who were treated non-operatively. All patients were included in a posttraumatic follow-up protocol with ultrasound examinations 4 and 12 weeks after injury. Results: The mean age of the children was 9.58 ± 3.97 years (range 1.98 to 17.75 years), with no statistically significant difference between the genders. The severity of the injury was determined according to the American Association for Surgery of Trauma (AAST) classification: 7 patients had grade I injuries (89.21%), 21 patients had grade II injuries (27.63%), 33 patients had grade III injuries (43.42%), and 15 patients had grade IV injuries (19.73%). The majority of the injuries were so-called high-energy ones, which were recorded in 45 patients (59.21%). According to a previously created posttraumatic follow-up protocol, complications were detected in 16 patients (21.05%). Hematomas had the highest incidence and were detected in 11 patients (14.47%), while pseudocysts were detected in 3 (3.94%), and a splenic abscess and pseudoaneurysm were detected in 1 patient (1.31%), respectively. The complications were in a direct correlation with injury grade: seven occurred in patients with grade IV injuries (9.21%), five occurred in children with grade III injuries (6.57%), three occurred in patients with grade II injuries (3.94%), and one occurred in a patient with a grade I injury (1.31%). Conclusion: Based on the severity of the spleen injury, it is difficult to predict the further course of developing complications, but complications are more common in high-grade injuries. The implementation of a follow-up ultrasound protocol is mandatory in all patients with NOM of spleen injuries for the early detection of potentially dangerous and fatal complications.
