Therapeutic Intervention for Osteoporosis of Surgical Cases With Non-Vertebral Fractures for Three Years in a Newly Established Rural Hospital in Japan.

Objectives Our hospital was newly opened in the spring of 2020 in a rural area of Japan, with a remarkably developing aging society and population decline. This study aimed to clarify and evaluate the practice of osteoporosis care in our hospital for three years since its establishment. We report a retrospective review of therapeutic interventions for osteoporosis for patients who underwent surgical treatment for non-vertebral fragility fractures in our hospital. Methods We evaluated the practice of osteoporosis intervention in patients who underwent surgery for proximal humerus fractures (PHFs), distal radius fractures (DRFs), or proximal femoral fractures (PFFs) from April 2020 to the end of March 2023. Results There were 115 surgical cases with non-vertebral fractures (10 patients with PHF, 41 patients with DRF, and 64 with PFF). Among the patients who had received osteoporosis treatment at other hospitals before the injury, only 15 (13.0%) patients had been administered therapeutic intervention for osteoporosis by other clinics or hospitals. Also, 82 (71.3%) patients were newly diagnosed with osteoporosis in our hospital after surgery according to the Japanese osteoporosis guideline. New postoperative osteoporosis interventions were administered to 39 (47.0%) patients, of which the rate was higher than the previous reports in Japan. While there was no significant difference between upper limb fracture and PFF in the percentage per young adult mean of spine areal bone marrow density (aBMD), the femoral neck aBMDs in the upper limb fracture group were significantly higher than in the PFF group. The serum total P1NP levels were significantly lower and the 25(OH)D levels were also greater in the upper limb fracture group than in the PFF group, whereas the serum TRACP-5b levels were not significantly different between the two groups. Two (1.7%) patients were affected with secondary fractures during the study period. Conclusions The rates of therapeutic intervention for osteoporosis of patients with non-vertebral fractures, especially in those with upper limb fractures, in our hospital were considered to be greater than those in the previous reports. However, the intervention rate for patients with PFFs was not much, and there was still room for improvement in our hospital concerning osteoporosis diagnosis and treatment.

Comparison of the rate of concomitant proximal venous stenosis between the upper and lower extremities in patients with secondary lymphedema undergoing lymphaticovenous anastomosis

BackgroundConcomitant iatrogenic proximal venous stenosis increases venous pressure and can be a risk factor for unfavorable outcomes of lymphaticovenular anastomosis (LVA) in extremities with secondary lymphedema. This study investigated the frequency and relevant factors of venous stenosis in patients diagnosed with secondary lymphedema who underwent LVA. MethodsPatients who underwent preoperative computed tomographic venography (CTV) and LVA for secondary lymphedema of the extremities from October 2018 to March 2022 were included. The incidence of proximal venous stenosis in the affected limb on preoperative CTV and the rate of endovascular intervention were compared between upper and lower extremities. Factors affecting proximal venous stenosis were identified through multivariable analysis using independent variables, including patient age, body mass index, comorbidities, smoking history, radiation therapy, duration of lymphedema, and location of lymphedema. ResultsA total of 211 patients were analyzed, including 83 patients with upper extremity and 128 patients with lower extremity lymphedema. The incidence of proximal venous stenosis in the preoperative CTV was 32.5% and 7.8% in upper extremity, and lower extremity lymphedema, respectively (P < .001). The incidence of venous stenosis requiring endovascular intervention was significantly higher in the upper extremity compared with the lower extremity (16.9% vs 6.3%; P = .014). In multivariable analysis, risk factors affecting incidence of venous stenosis requiring endovascular intervention was the patient age (P = .007) and upper extremity (P = .009). ConclusionsPreoperative evaluation and treatment of venous stenosis in extremities with secondary lymphedema are necessary before LVA surgery, particularly in upper extremity lymphedema.

A serial case study of the combined use of intraoperative CT and surgical navigation system for the removal of small foreign bodies in the maxillofacial region

PurposeThe removal of small foreign bodies embedded within the deep soft tissues of the maxillofacial region is a complex and challenging task for maxillofacial surgeons. The purpose of this study was to explore the efficacy of the combination of intraoperative CT and surgical navigation for the removal of small foreign objects in the maxillofacial region. MethodsA serial case study was conducted involving all consecutive patients who underwent surgical removal of small foreign bodies in the maxillofacial region. The combination of intraoperative CT and a surgical navigation system was used at a single medical institution from January 2018 to December 2022. Comprehensive data, including patient demographics, characteristics of the foreign bodies, previous surgical interventions, duration of the surgical procedure, and removal success rate were collected for this study. Relevant data were recorded into Microsoft Excel sheet and analyzed using SPSS version 22.0. ResultsNine patients (6 males and 3 females) were included in this study, with an average age of 37 years. Each patient had previously undergone an unsuccessful removal attempt utilizing conventional surgical methods based on preoperative CT imaging or C-arm guidance at a local healthcare facility. Four patients also experienced unsuccessful attempts with preoperative CT image-based navigation systems. However, by employing the combined approach of intraoperative CT and surgical navigation, the foreign bodies were successfully removed in all 9 patients. The mean duration of the surgical procedure was 59 min, and the average size of the foreign bodies was approximately 26 mm³. Postoperative follow-up exceeding 6 months revealed no complications. ConclusionThe combined use of a surgical navigation system and intraoperative CT represents a potent and effective strategy for the precise localization and subsequent removal of small foreign bodies from the soft tissue structures of the maxillofacial region. This integrative approach appears to increase the success rate of surgical interventions in such cases.

Validating the CHAMPS Score: A Novel and Reliable Prognostic Score of Non-Variceal Upper Gastrointestinal Bleeding.

The Charlson Comorbidity Index ≥2, in-Hospital onset, Albumin <2.5 g/dL, altered Mental status, Eastern Cooperative Oncology Group Performance status ≥2, Steroid use (CHAMPS) score is a novel and promising prognostic tool. We present an initial external validation of the CHAMPS score for predicting mortality in acute nonvariceal upper gastrointestinal bleeding (NVUGIB) across multiple clinical outcomes. A prospective cohort study was conducted on adult patients with NVUGIB admitted to the Department of Gastroenterology between November 2022 and June 2023. The CHAMPS score performance in predicting in-hospital outcomes was evaluated by employing area under the receiver operating characteristic (AUROC) curves, followed by a comparative analysis with five pre-existing scores. A total of 140 patients were included in the study. The CHAMPS score showed its highest performance in predicting mortality rates (AUROC = 0.89), significantly outperforming the Glasgow-Blatchford Bleeding Score (GBS) as well as the Albumin level <3.0 mg/dL, International normalized ratio >1.5, altered Mental status, Systolic blood pressure ≤90 mmHg, and age >65 years (AIMS65) score (AUROC = 0.72 and 0.71, respectively; all p < 0.05). Subgroup analysis for bleeding-related and non-bleeding-related mortality further confirmed the robust predictive capability of the CHAMPS score (AUROC = 0.88 and 0.87, respectively). The CHAMPS score failed to predict rebleeding and intervention reliably, exhibiting AUROC values of 0.43 and 0.55, respectively. The optimal CHAMPS score cutoff value for predicting mortality was 3 points, achieving 100% sensitivity and 71.2% specificity. In the low-risk category defined by both CHAMPS and GBS scores, mortality and rebleeding rates were 0%. However, within the CHAMPS score-based low-risk group, 58.8% required intervention, contrasting with a 0% intervention rate for the GBS score-based low-risk group (GBS score ≤1). The CHAMPS score consistently demonstrated a robust predictive performance for mortality (AUROC > 0.8), facilitating the identification of high-risk patients requiring aggressive treatment and low-risk patients in need of localized treatment or safe discharge after successful bleeding control.

Association of Operative Approach With Postoperative Outcomes in Neonates Undergoing Surgical Repair of Esophageal Atresia and Tracheoesophageal Fistula

IntroductionMinimally invasive surgery (MIS) is gaining traction as a first-line approach to repair congenital anomalies. This study aims to evaluate outcomes for neonates undergoing open versus MIS repairs for esophageal atresia/tracheoesophageal fistula (EA/TEF). MethodsIn this retrospective study, neonates undergoing EA/TEF repair from 2013 to 2020 were identified using the National Surgical Quality Improvement Program-Pediatric database. Proportions of operative approach (open vs. MIS) over time were analyzed. A propensity score-matched analysis using preoperative characteristics was performed and outcomes were compared including composite morbidity and reintervention rates (overall, major [thoracoscopy, thoracotomy], and minor [chest/feeding tube placement, endoscopy]) between operative approaches. Pearson's chi-square or Fisher's exact tests were used as appropriate. ResultsWe identified 1738 neonates who underwent EA/TEF repair. MIS utilization increased over time. Pre-match, neonates undergoing open repair were more likely to be premature, lower weight, ventilator dependent, and have cardiac risk factors with higher severity. Post-match, the groups were similar and included 340 neonates per group. MIS repair was associated with longer median operative time (209 vs. 174 min, p < 0.001) and increased overall post-operative intervention rates (7.6% vs. 2.9%, p = 0.01). There were no differences in composite morbidity (24.4% vs. 25.0%, p = 0.86) outside of reintervention. ConclusionMIS approach for neonates with EA/TEF appears to be associated with a higher rate of reinterventions. Further studies evaluating MIS approaches for the repair of EA/TEF are needed to better define short- and long-term outcomes. Type of StudyRetrospective comparative study.

Standardized Gastrografin Protocol for Small Bowel Obstructions in Community Hospital Setting

Introduction: Small bowel obstructions (SBO) are diagnosed and treated variously. The purpose of this study is to determine whether the use of Gastrografin oral hyperosmolar contrast and serial abdominal X-rays will lead to a decreased length of stay, readmission rate, and need for surgical intervention versus current management of patients with SBO. Methods: A retrospective review of patients who presented to our hospital with the diagnosis of SBO over two years was performed. Patients were excluded if their clinical status led to emergent operative intervention, were admitted within 30 days of bowel surgery, or were &lt;18 years old. The leading variable for analysis was patients undergoing Gastrografin protocol versus those that did not. The leading outcome was hospital length of stay. Secondary outcomes included number of CT scans during admission, progression to surgery and 30-day readmission rate. Analyses were performed using both unpaired T-tests and Chi-squared tests. Results: A total of 55 patients with a SBO that met study criteria were reviewed. Total patients who underwent Gastrografin protocol were 24 versus 31 who did not. Gastrografin protocol patients had a decreased length of stay (mean, 2.2 days vs 3.9 days, p=0.0048) and decreased number of CT scans during admission (mean, 1.0 scans vs 1.35 scans, p=0.0027) compared to non-protocol patients. Both Gastrografin protocol and non-protocol groups had similar progression to surgical intervention (4.2% vs 16.1%, p =0.158) and 30-day readmission rate (12.5% vs 16.1%, p=0.70). Conclusion: The Gastrografin protocol decreases length of stay and number of CT scans for patients admitted with SBO.

Implementation Rate of Physical Rehabilitation in Neonatal Intensive Care Units in Japan: A Retrospective Observational Study.

Background and Objective: The benefits of physical rehabilitation for very-low-birth-weight infants (VLBWI) have been reported in previous studies; however, the implementation rate of physical rehabilitation in this population remains to be clarified. This study aimed to examine the implementation rate of physical rehabilitation among VLBWI admitted to the neonatal intensive care unit (NICU) using real-world data. Material and Methods: This observational study obtained data from a nationwide administrative database associated with the diagnostic procedure combination (DPC) system in Japan (2014-2019). The participants were 30,464 infants admitted to the NICU between 2014 and 2019. The overall NICU physical rehabilitation rates and background factors of the participants were examined. Results: The overall physical rehabilitation rate in NICUs was 18%. Infants born at <28 weeks of age and extremely low birth weight infants (ELBWI) were more likely to receive physical rehabilitation interventions. The length of stay at the NICU and hospital, as well as the rate of discharge, were higher in patients who received physical rehabilitation than those in infants who did not. Conclusions: One-fifth of all patients admitted to the NICU received physical rehabilitation interventions. Extremely preterm infants and ELBWI were more likely to receive physical rehabilitation interventions. We need to consider ways to increase physical rehabilitation intervention rates in the NICU.

A real-world study evaluating the safety and utility of a two-row stapler reload on pulmonary vasculature.

Endoscopic staplers are common surgical devices used for the ligation and division of vasculature in thoracic procedures. When a stapler ligates and divides pulmonary vasculature, potentially catastrophic intraoperative bleeding at the staple-line may occur. The aim of this study was to confirm the safety and discuss the utility of a two-row stapler reload, by assessing the incidence of clinically necessary intraoperative hemostatic intervention when applied to pulmonary vasculature in real-world applications. This study was designed as a prospective non-comparative registry study conducted in seven centers across the United States, to confirm the safety and performance of Signia™ Small Diameter Reloads (SDR) when used for indicated thoracic surgical procedures. The primary endpoint was the incidence of hemostatic intervention related to the ligation and division of pulmonary arteries and veins. A five-point Likert scale scored hemostasis of each SDR staple-line. Secondary endpoints included the incidence of device-related only adverse events (AEs), device deficiencies, and procedure-related hospital readmission up to and including 30 days post operation. SDR was fired 302 times across pulmonary vasculature in 120 subjects. Three firings required clinically necessary hemostatic intervention for an intervention rate of 0.99% (3 of 302 firings). Moreover, 97.5% (117 of 120 subjects) had intact SDR staple-lines regardless of surgical access or stapler handle preference. Only 4 (3.3%) thoracoscopic and robotic procedures converted to open, but none were due to SDR staple-lines. There was no statistically significant difference between the Likert score of transected arteries compared to veins (P=0.61). There were no device deficiencies or device-only related AEs reported. In this study, the two-row stapler reloads demonstrated favorable safety and efficacy profiles when fired across hilar vessels in the thoracic space with a 99% hemostatic rate, independent of surgical access and stapler handle preference.

Using the GAP score as a complement to the NISS score in identifying severely injured patients- A registry-based cohort study of adult trauma patients in Sweden

BackgroundNew Injury Severity Score (NISS) and Glasgow Coma Scale, Age and Pressure (GAP) scoring systems have cutoffs to define severe injury and identify high-risk patients. This is important in trauma quality monitoring and improvement. The overall aim was to explore if GAP scoring system can be a complement or an alternative to the traditional NISS scoring system. MethodsAdults exposed to trauma between 2017 and 2021 were included in the study, using data from The Swedish Trauma Registry. The performance of NISS and GAP scores in predicting mortality, and ICU admissions were assessed using the area under the receiver operator characteristics (AUROC) in all patients and in subgroups (blunt, penetrating trauma and older (≥65 years) trauma patients). Patients were classified as severely injured by NISS >15 as Severely Injured NISS (SIN) or with a high-risk for mortality, by GAP 3–18 as High Risk GAP (HRG). Undertriage was calculated based on the cutoffs HRG and SIN. ResultsOverall, 37,017 patients were included. The AUROC (95 % CI) for mortality using NISS was 0.84 (0.83–0.85) and for GAP 0.92 (0.91–0.93) (p-value <0.001), the AUROC (95 % CI) for ICU-admissions was 0.82 (0.82–0.83) using NISS and for GAP 0.70 (0.70–0.71) p-value <0.001, in the overall cohort. In older patients the AUROC (95 % CI) for mortality was 0.76 (0.75–0.78) using NISS and 0.79 (0.78–0.81) using GAP, p-value <0.001. Overall, 8,572 (23.2 %) and 2,908 (7.9 %) were classified as SIN and HRG, respectively, with mortality rates of 13.7 % and 34.3 %. In the HRG group low-energy falls dominated and in the SIN group most patients were exposed to MVCs. In the SIN and HRG groups the rate of Emergency Trauma Interventions according to Utstein guidelines (ETIU) and ICU admission was 14.0 vs 9.5 % and 47.0 vs 62.5 % respectively. ConclusionOur findings suggest that the GAP score and its cutoff 3–18 can be used to define severe trauma as complement to NISS >15 and can be a valuable tool in trauma quality monitoring and improvement. However, both scoring systems were less accurate in predicting mortality for the older trauma patients and should be explored further.

Neonatal Outcomes of Infants Diagnosed with Fetal Growth Restriction during Late Pregnancy versus after Birth.

Objective: The aim of this study was to investigate the potential differences in the outcomes of neonates in whom FGR was diagnosed late in pregnancy as compared to those in whom growth restriction was diagnosed after birth. Methods: A retrospective study was conducted in a tertiary medical center between 2017 and 2019. The study included women carrying a single infant with an estimated fetal weight below the tenth percentile in whom FGR was diagnosed during late pregnancy, after 32 gestational weeks (known late-onset FGR; study group) or only after birth (unknown FGR; control group). Data were collected by review of the electronic health records. The primary outcome measure was the rate of composite adverse neonatal outcome. Results: A total of 328 women were included, 77 (23.47%) in the known-FGR group and 251 (75.53%) in the unknown-FGR group. In the known-FGR group, an etiology for the FGR was identified in 28.57% cases, most commonly placental insufficiency (21.74%). Compared to the unknown-FGR group, the known-FGR group was characterized by significantly higher rates of elective cesarean delivery (15.58% vs. 9.96%, p < 0.001), preterm birth (18.18% vs. 3.98%, p < 0.01), and labor induction (67.53% vs. 21.51%, p < 0.01). A significantly higher proportion of neonates in the known-FGR group had a positive composite adverse outcome (38.96% vs. 15.53%, p < 0.01). For multivariate regression analysis adjusted for maternal age, gestational age at delivery, and mode of delivery, there was no difference between groups in the primary outcome (aOR 1.73, CI 0.89-3.35, p = 0.1). Every additional gestational week at delivery was a protective factor (aOR = 0.7, 95% CI 0.56-0.86, p < 0.01). Conclusions: A prenatal diagnosis of late-onset FGR is associated with higher intervention and preterm birth rates as compared to a diagnosis made after birth. Fetuses diagnosed with late-onset FGR during pregnancy should undergo specific and personalized assessment to determine the cause and severity of the growth delay and the best management strategy. This study highlights the importance of careful decision-making regarding the induction of labor in late-onset FGR.

Correlation between types of ventricular septal defect and chromosomal abnormalities in low-risk non-invasive prenatal testing.

The aim of this study was to examine whether there is a correlation between different types of ventricular septal defects (VSD) and chromosomal abnormalities in the low-risk setting of non-invasive prenatal testing (NIPT) and to evaluate the prognosis of fetuses with varying types of VSD. Cases of pregnant women who underwent amniocentesis due to fetal VSD were collected by Tianjin Central Hospital of Obstetrics and Gynecology from May 2017 to May 2022. Exclusions were made for those without NIPT, with high-risk NIPT results, genetic disorders, and those lost to follow-up. Data collected included ultrasound classification of VSD, prenatal NIPT results, copy-number variations (CNVs) results, and neonatal outcomes. The prevalence of pathogenic CNVs was investigated in 74 cases of VSDs. Of these cases, 45 were isolated VSDs (9 muscular and 36 non-muscular) and 29 were non-isolated VSDs (10 with intracardiac and 19 with extra-cardiac structural anomalies). The results revealed that the incidence of pathogenic CNVs was lower in isolated VSDs compared to non-isolated VSDs in a low-risk NIPT condition (χ2 = 9.344, P = 0.002). There was no significant difference in the prevalence of pathogenic CNVs between VSDs with intracardiac and extra-cardiac structural anomalies (P = 0.541). Moreover, VSDs associated with intracardiac structural anomalies had the highest rate of surgical intervention. When NIPT is low-risk and VSD is isolated, the likelihood of fetal chromosomal defects is not increased. However, if there are intra- or extra-cardiac structural abnormalities present alongside VSD, the possibility of pathogenic CNV is considerably greater, necessitating invasive prenatal diagnosis. Isolated muscular VSDs usually do not require surgery, which can be used as a basis for prenatal counseling regarding fetal VSD.

Hospital teaching status is an independent predictor of surgical intervention of distal radius fractures

BackgroundDistal radius fractures are among the most common orthopaedic injuries and are managed both surgically and non-surgically. To date, no study has examined the role hospital teaching status plays in the rates of surgical intervention. MethodsThe Nationwide Inpatient Sample (NIS) was queried for years 2003–2014. Patients with a distal radius fracture were identified using International Classification for Disease, Ninth Revision (ICD-9) disease codes. Surgical intervention was determined using ICD-9 procedure codes. Exclusion criteria were patients younger than age 18, polytrauma, open fractures, records with missing data, and records where the primary procedure was something other than open reduction of a radius or ulna fracture, closed reduction of a radius or ulna fracture, or blank. Chi-squared tests were run for demographic and socioeconomic data to identify significant variables. Significant variables were then included alongside hospital teaching status in a binomial logistic regression model. Significance was defined as P < 0.05. ResultsA weighted total of 98,831 patients were included in the study. Of those, 45,234 (45.8 %) were treated at teaching hospitals. Patients in teaching hospitals were more likely to be younger, male, non-white, and non-Medicare insured than non-teaching hospitals. Injuries were treated surgically in 64.6 % of total cases. Surgical intervention was more common in teaching hospitals than non-teaching hospitals (69.1 % vs. 60.8 %, P < 0.01). After controlling for demographic and socioeconomic factors, patients at teaching hospitals were 31 % more likely to undergo surgical treatment than those at non-teaching hospitals. Other factors that were independently predictive of surgical treatment were age, race, and insurance type. ConclusionIn the setting of distal radius fractures, teaching hospitals have higher rates of surgical intervention than non-teaching hospitals. These results suggest that the involvement of medical trainees may play a role in the surgical decision-making process.

Prognostic Association between Injury Severity Score and the Outcomes of Elderly Patients with Trauma in South Korea.

This study investigated the impact of the Injury Severity Score (ISS) on treatment approaches and survival outcomes in trauma patients, focusing on comparing elderly (≥65 years) with non-elderly patients. It analyzed adult trauma cases with abnormal Revised Trauma Scores from January to December 2019, categorizing patients into three severity groups based on ISS: mild (1-8), moderate (9-15), and severe (≥16). The study examined how ISS influenced therapeutic interventions and survival among elderly patients, comparing these outcomes to non-elderly patients using multivariable logistic regression analysis. In 16,336 adult trauma cases out of 52,262 patients, including 4886 elderly and 11,450 non-elderly patients, findings revealed that in the severe group, elderly patients had a lower, though not statistically significant, incidence of surgical or embolization interventions compared to the moderate group, differing from non-elderly patients. No significant differences were observed in the mild group between elderly and non-elderly patients. However, elderly patients had higher intervention rates in the moderate group and lower in the severe group, with significantly lower survival-to-discharge rates in the severe group. The ISS is insufficient for assessing trauma severity in elderly patients. Additional tools are needed for better evaluation and treatment decisions.

Demographic Characteristics and Factors Associated with Acute Scaphoid Fractures: An Analysis of 903 Patients

Objectives A comprehensive understanding of the epidemiology of scaphoid fractures is crucial to aid in diagnosing and treating patients with suspected injuries. The study aims to assess demographic characteristics and factors associated with acute scaphoid fractures in adults. Methods A retrospective review identified all patients with acute scaphoid fractures over four years at a single institution. Data collected included baseline demographics (age, biological sex, race, and ethnicity), body mass index, tobacco and alcohol use, pertinent medical history, and treatment modality. Laterality, location, and displacement of the fracture were confirmed on radiographic analysis. Results A total of 903 scaphoid fractures were included. The majority of fractures occurred in males (n=570, 63%) and were in the left hand (54%), unilateral (99%), nondisplaced (71%), and treated definitively with nonoperative management (71%). Nearly two-thirds (66%) of fractures occurred along the scaphoid waist, followed by the distal third of the scaphoid (25%). Proximal third fractures accounted for the smallest proportion of scaphoid fractures (8.6%) but had the highest displacement and surgical intervention rates compared to waist and distal third fractures. Younger age, male sex, fractures of the proximal third, and displaced fractures had higher odds of being treated surgically. Conclusion The scaphoid is one of the most frequently fractured carpal bones. Young adult males may be at an increased risk for injury. Patients with displaced fractures and those involving the proximal third require surgical intervention at higher rates.

Bicuspid Aortic Valve Disease with Early-Onset Complications: Characteristics and Aortic Outcomes

Bicuspid aortic valve (BAV) is the most common congenital heart malformation in adults, but it can also cause childhood-onset complications. The presentation and clinical course of young adults who present due to BAV complications are relatively uncharacterized. In a multicenter study, we found that young people who experience significant complications related to BAV disease before age 30 are distinguished from the majority of BAV cases that manifest after age 50 by a relatively severe clinical course, with higher rates of surgical interventions, more frequent second interventions, and a greater burden of congenital heart malformations. These observations highlight the need for prompt recognition, regular lifelong surveillance, and targeted interventions to address the significant health burdens of patients with early-onset BAV complications.

Gait-Guard: Turn-aware Freezing of Gait Detection for Non-intrusive Intervention Systems.

Freezing of gait significantly reduces the quality of life for Parkinson's disease patients by increasing the risk of injurious falls and reducing mobility. Real-time intervention mechanisms promise relief from these symptoms, but require accurate real-time, portable freezing of gait detection systems to be effective. Current real-time detection systems have unacceptable false positive freezing of gait identification rates to be adopted by the patients for real-world use. To rectify this, we propose Gait-Guard, a closed-loop, real-time, and portable freezing of gait detection and intervention system that treats symptoms in real-time with a low false positive rate. We collected 1591 freezing of gait events across 26 patients to evaluate Gait-Guard. Gait-Guard achieved a 112% reduction in the false positive intervention rate when compared with other validated real-time freezing of gait detection systems, and detected 96.5% of the true positives with an average intervention latency of just 378.5ms in a subject-independent study, making Gait-Guard a practical system for patients to use in their daily lives.

Is Aggressive Surgery Always Necessary for Suspected Early-Onset Surgical Site Infection after Lumbar Surgery? A 10-Year Retrospective Analysis.

Surgical site infection (SSI) after spinal surgery is still a persistent worldwide health concern as it is a worrying and devastating complication. The number of samples in previous studies is limited and the role of conservative antibiotic therapy has not been established. This study aims to evaluate the clinical efficacy and feasibility of empirical antibiotic treatment for suspected early-onset deep spinal SSI. We conducted a retrospective study to identify all cases with suspected early-onset deep SSI after lumbar instrumented surgery between January 2009 and December 2018. We evaluated the potential risks for antibiotic treatment, examined the antibiotic treatment failure rate, and applied logistic regression analysis to assess the risk factors for empirical antibiotic treatment failure. Over the past 10 years, 45 patients matched the inclusion criteria. The success rate of antibiotic treatment was 62.2% (28/45). Of the 17 patients who failed antibiotic treatment, 16 were cured after a debridement intervention and the remaining one required removal of the internal fixation before recovery. On univariate analysis, risk factors for antibiotic treatment failure included age, increasing or persisting back pain, wound dehiscence, localized swelling, and time to SSI (cut-off: 10 days). Multivariate analysis revealed that infection occurring 10 days after primary surgery and wound dehiscence were independent risk factors for antibiotic treatment failure. Appropriate antibiotic treatment is an alternative strategy for suspected early-onset deep SSI after lumbar instrumented surgery. Antibiotic treatment for suspected SSI occurring within 10 days after primary surgery may improve the success rate of antibiotic intervention. Patients with wound dehiscence have a significantly higher likelihood of requiring surgical intervention.

Importance of parental anxiety in management of developmental breast conditions in children: A study with a prospective hierarchical regression model.

The parent is the most critical link and decision-maker between the patient and the healthcare provider in treating many pediatric diseases. This entity is essential for the management of pediatric breast diseases for which the rate of surgical intervention is known to be very low. Although previous publications have emphasized that pediatric breast diseases may cause alarming anxiety in parents, the demographic factors that influence this anxiety have not been investigated. Even if practitioners complete patient management with appropriate procedures, treatment is incomplete if the questions remain unanswered. In this observational prospective study, we investigated the demographic factors that affect parental anxiety, which should be prioritized to prevent incomplete management. The Beck Anxiety Inventory score (BAS) created by the parents of 409 boys and girls aged 0 to 17 with breast conditions was recorded at the diagnosis, termination of treatment, and final control stages. A 2-stage hierarchical logistic regression model was applied to show how strongly the demographic characteristics of parents and their children predicted the parental BAS. Of the demographic characteristics, there was a significant correlation (P < .05) between the patient's sex, age, developmental period, Tanner stage, referral status, management method, family's place of residence, economic distress, and BAS. However, according to the 2-stage hierarchical regression model, only 3 demographic characteristics, the patient's gender, place of residence, and method used in patient management, significantly predicted BAS (P < .05, ΔR2 = .35). Among the many factors that affect anxiety experienced by parents whose son or daughter has breast problems, the gender of the child, place of residence of the family, and management methods used by the practitioner are demographic characteristics that should be taken into consideration.
