Natural language processing pipeline to extract prostate cancer-related information from clinical notes.

OBJECTIVES: To develop an automated pipeline for extracting prostate cancer-related information from clinical notes. MATERIALS AND METHODS: This retrospective study included 23,225 patients who underwent prostate MRI between 2017 and 2022. Cancer risk factors (family history of cancer and digital rectal exam findings), pre-MRI prostate pathology, and treatment history of prostate cancer were extracted from free-text clinical notes in English as binary or multi-class classification tasks. Any sentence containing pre-defined keywords was extracted from clinical notes within one year before the MRI. After manually creating sentence-level datasets with ground truth, Bidirectional Encoder Representations from Transformers (BERT)-based sentence-level models were fine-tuned using the extracted sentence as input and the category as output. The patient-level output was determined by compilation of multiple sentence-level outputs using tree-based models. Sentence-level classification performance was evaluated using the area under the receiver operating characteristic curve (AUC) on 15% of the sentence-level dataset (sentence-level test set). The patient-level classification performance was evaluated on the patient-level test set created by radiologists by reviewing the clinical notes of 603 patients. Accuracy and sensitivity were compared between the pipeline and radiologists. RESULTS: Sentence-level AUCs were ≥ 0.94. The pipeline showed higher patient-level sensitivity for extracting cancer risk factors (e.g., family history of prostate cancer, 96.5% vs. 77.9%, p < 0.001), but lower accuracy in classifying pre-MRI prostate pathology (92.5% vs. 95.9%, p = 0.002) and treatment history of prostate cancer (95.5% vs. 97.7%, p = 0.03) than radiologists, respectively. CONCLUSION: The proposed pipeline showed promising performance, especially for extracting cancer risk factors from patient's clinical notes. CLINICAL RELEVANCE STATEMENT: The natural language processing pipeline showed a higher sensitivity for extracting prostate cancer risk factors than radiologists and may help efficiently gather relevant text information when interpreting prostate MRI. KEY POINTS: When interpreting prostate MRI, it is necessary to extract prostate cancer-related information from clinical notes. This pipeline extracted the presence of prostate cancer risk factors with higher sensitivity than radiologists. Natural language processing may help radiologists efficiently gather relevant prostate cancer-related text information.

Characterization of pain-related behaviors in a rat model of acute-to-chronic low back pain: single vs. multi-level disc injury.

Introduction: Low back pain is the most common type of chronic pain. We examined pain-related behaviors across 18 weeks in rats that received injury to one or two lumbar intervertebral discs (IVD) to determine if multi-level disc injuries enhance/prolong pain. Methods: Twenty-three Sprague-Dawley adult female rats were used: 8 received disc puncture (DP) of one lumbar IVD (L5/6, DP-1); 8 received DP of two lumbar IVDs (L4/5 & L5/6, DP-2); 8 underwent sham surgery. Results: DP-2 rats showed local (low back) sensitivity to pressure at 6- and 12-weeks post-injury, and remote sensitivity to pressure (upper thighs) at 12- and 18-weeks and touch (hind paws) at 6, 12 and 18-weeks. DP-1 rats showed local and remote pressure sensitivity at 12-weeks only (and no tactile sensitivity), relative to Sham DP rats. Both DP groups showed reduced distance traveled during gait testing over multiple weeks, compared to pre-injury; only DP-2 rats showed reduced distance relative to Sham DP rats at 12-weeks. DP-2 rats displayed reduced positive interactions with a novel adult female rat at 3-weeks and hesitation and freezing during gait assays from 6-weeks onwards. At study end (18-weeks), radiological and histological analyses revealed reduced disc height and degeneration of punctured IVDs. Serum BDNF and TNFα levels were higher at 18-weeks in DP-2 rats, relative to Sham DP rats, and levels correlated positively with remote sensitivity in hind paws (tactile) and thighs (pressure). Discussion: Thus, multi-level disc injuries resulted in earlier, prolonged and greater discomfort locally and remotely, than single-level disc injury. BDNF and TNFα may have contributing roles.

Pitch-classifier model for professional pitchers utilizing 3D motion capture and machine learning algorithms.

Introduction: A pitcher's ability to achieve pitch location precision after a complex series of motions is of paramount importance. Kinematics have been used in analyzing performance benefits like ball velocity, as well as injury risk profile; however, prior utilization of such data for pitch location metrics is limited. Objective: To develop a pitch classifier model utilizing machine learning algorithms to explore the potential relationships between kinematic variables and a pitcher's ability to throw a strike or ball. Methods: This was a descriptive laboratory study involving professional baseball pitchers (n = 318) performing pitching tests under the setting of 3D motion-capture (480 Hz). Main outcome measures included accuracy, sensitivity, specificity, F1 score, positive predictive value (PPV), and negative predictive value (NPV) of the random forest model. Results: The optimized random forest model resulted in an accuracy of 70.0 %, sensitivity of 70.3 %, specificity of 48.5 %, F1 equal to 80.6 %, PPV of 94.3 %, and a NPV of 11.6 %. Classification accuracy for predicting strikes and balls achieved an area under the curve of 0.67. Kinematics that derived the highest % increase in mean square error included: trunk flexion excursion(4.06 %), pelvis obliquity at foot contact(4.03 %), and trunk rotation at hand separation(3.94 %). Pitchers who threw strikes had significantly less trunk rotation at hand separation(p = 0.004) and less trunk flexion at ball release(p = 0.003) compared to balls. The positive predictive value for determining a strike was within an acceptable range, while the negative predictive value suggests if a pitch was determined as a ball, the model was not adequate in its prediction. Conclusions: Kinematic measures of pelvis and trunk were crucial determinants for the pitch classifier sequence, suggesting pitcher kinematics at the proximal body segments may be useful in determining final pitch location.

Diabetes status and postoperative complications for patients receiving open rotator cuff repair.

Background: Diabetic patients are known to have poor wound healing and worse outcomes following surgeries. The purpose of this study is to evaluate diabetes status and complications for patients receiving open rotator cuff repair. Methods: Patients undergoing open rotator cuff repair from 2006 to 2018 were identified in a national database. Patients were stratified into 3 cohorts: no diabetes mellitus, non-insulin dependent diabetes mellitus (NIDDM), and insulin dependent diabetes mellitus (IDDM). Differences in demographics, comorbidities, and complications were assessed with the use of bivariate and multivariate analyses. Results: Of 7678 total patients undergoing open rotator cuff repair, 6256 patients (81.5%) had no diabetes, 975 (12.7%) had NIDDM, and 447 (5.8%) had IDDM. Bivariate analyses revealed that IDDM patients had increased risk of mortality, extended length of stay, and readmission compared to non-diabetic patients (p < 0.05 for all). IDDM patients had higher risks of major complications and readmission relative to NIDDM patients (p < 0.05 for both). On multivariate analysis, there were no differences in any postoperative complications between the non-diabetic, NIDDM, and IDDM groups. Discussion: Diabetes does not affect postoperative complications following open rotator cuff repairs. Physicians should be aware of this finding and counsel their patients appropriately.Level of Evidence: III.

Kinematic and Kinetic Comparisons of Arm Slot Position Between High School and Professional Pitchers.

Background: Throwing arm kinetics differ in pitchers at varying arm slot (AS) positions (frontal-plane arm position at ball release relative to the vertical axis). Purpose: To determine how kinematic and kinetic values differ between professional and high school pitchers with varying AS positions, and whether these differences are similarly observed in both populations. Methods: High school (n = 130) and professional (n = 288) pitchers threw 8 to 12 fastballs under 3-dimensional motion capture technology. Pitchers in each cohort were subdivided based on mean AS position at ball release: AS1 (least degree of AS: most overhand throwing styles), AS2 (intermediate degree of AS: three-quarter throwing styles), or AS3 (greatest degree of AS: most sidearm throwing styles). Kinetic and kinematic parameters were compared between groups. Study Design: Controlled laboratory study. Results: High school pitchers had a more overhand AS at ball release (50° ± 11°) compared with professional pitchers (58° ± 14°) (P < .001). In both cohorts, AS1 pitchers had significantly greater shoulder abduction (high school, P <0.001; professional, P <0.0001) and lateral trunk flexion (high school, P < 0.001; professional, P <0.0001) at ball release compared with AS3 pitchers. Professional pitchers with an AS3 position had significantly delayed timing of maximum upper trunk angular velocity compared with AS1 pitchers (64% ± 7% vs 57% ± 7% of pitch time, respectively; P < .0001). A significant positive correlation between AS and elbow flexion torque was found in high school pitchers (P = .002; ß = 0.28), and a significant negative correlation between AS and elbow varus torque (P < .001; ß = -0.22) and shoulder internal rotation torque (P < .001; ß = -0.20) was noted in professional pitchers. Conclusion: AS position was related to shoulder abduction and trunk lateral tilt. Professional and high school pitchers with varying AS positions did not experience similar changes in throwing arm kinetics. Clinical Relevance: In professional pitchers, the earlier onset of maximum upper trunk angular velocity with overhand throwing style may reflect inappropriate pelvis-trunk timing separation, a parameter implicated in upper extremity injury, and the negative correlation between AS and elbow varus and shoulder internal rotation torque suggests that both excessive and minimal AS positions have negative implications.

A Clinical Review of Mesenteric Panniculitis.

Mesenteric panniculitis (MP) is a benign condition characterized by chronic inflammation and fibrosis of adipose tissue mainly of the small bowel mesentery. MP is commonly detected incidentally on cross-sectional imaging of the abdomen and can be asymptomatic in up to nearly half of patients. The most frequent clinical symptom reported is abdominal pain, followed by bloating/distention, diarrhea, constipation, vomiting, anorexia, weight loss, fever, malaise, and nausea. On computed tomography, MP is seen as a mass-like area of increased fat attenuation within the small bowel mesentery, usually located in the left upper quadrant of the abdomen. This mass-like area envelops mesenteric vessels and displaces adjacent bowel segments. Lymph nodes are frequently seen within the area of mesenteric abnormality. One of the most common differential diagnoses of MP is lymphoma, and positron emission tomography/computed tomography may be performed if there is suspicion of a concurrent underlying malignancy. Because of the benign nature of MP, treatment decisions should be guided by severity of symptoms and presence of complications. First-line medical treatment is prednisone and tamoxifen. Surgery is reserved for cases of recurrent bowel obstruction. This article provides a review of MP, including its epidemiology, pathophysiology, clinical presentation, imaging findings, and treatment.

The Effect of Steroid Use on Complications after Distal Radius Fracture Repair.

Background Distal radius fractures (DRFs) are the most common fracture of the upper extremity. Given that steroids are one of the most commonly prescribed drugs and are usually prescribed for chronic conditions, steroid use represents a key factor to consider in how to optimize perioperative outcomes. Questions/Purposes The purpose of this study was to investigate if there are differences in perioperative outcomes for patients undergoing DRF open reduction and internal fixation based on preoperative steroid use. Patients and Methods Adult patients who underwent operative treatment for DRF from 2007 to 2018 were identified in a national database. Patients were divided into two cohorts as follows: (1) no steroid usage and (2) preoperative steroid usage. In this analysis, various postoperative complications, as well as extended length of stay and reoperation, were assessed. Bivariate analyses and multivariable logistical regression were performed. Results Among a total of 16,505 patients undergoing operative treatment for DRF, 16,145 patients (97.8%) did not have steroid usage and 360 (2.2%) had steroid usage. Following adjustment, an increased risk of extended length of hospital stay greater than 3 days (odds ratio [OR] = 1.646; p = 0.012) was seen in the steroid usage group compared with those who did not use steroids within 30 days of surgery. Conclusion Preoperative steroid use is associated with increased length of stay over 3 days after DRF open reduction and internal fixation surgery but is not associated with any of the other complications that were assessed in this study. Level of Evidence This is a Level III, retrospective study.

Association of social isolation with health status among community-dwelling Chinese older adults living with homecare services: a cross-sectional survey in Hong Kong.

Background: Defined as having few social relationships or infrequent social contact with family, friends, and the community, social isolation is a public health crisis. We aimed to evaluate the prevalence of social isolation and explore the association between social isolation and health status among community-dwelling Chinese Older Adults living with homecare services. Methods: This is a cross-sectional survey with a structured questionnaire conducted among older adults aged ≥60 in the Central Kowloon District of Hong Kong during 2017-2018. Social isolation was assessed by the Lubben Social Network Scale-6 and a score less than 12 was defined as socially isolated. Six aspects of health status including fall risk, cognitive function, depression, activities of daily living (ADL), instrumental activities of daily living (IADL), and functional mobility were measured by standardized instruments. Multi-criteria decision analysis (MCDA) was applied to estimate an index to represent the overall health status of the respondents. Multivariate logistic/linear regression models were applied to examine the associations between social isolation and health status after adjusting the sociodemographic characteristics. Results: Among the 1,616 participants included in this analysis, the mean age was 80.9 years, 66.3% were female and 41.4% were identified as socially isolated. Compared with the non-isolated group, the socially isolated group had higher proportions of males, divorced or unmarried, ever smoking and drinking, living alone, and living in public housing without religion. After adjusting for confounders, the odds ratios (OR) comparing the socially isolated vs. non-isolated groups were 2.52 (95%CI: 1.79, 3.56) for high fall risk, 1.51 (1.17, 1.94) for cognitive impairment, and 1.78 (1.31, 2.43) for depression. The socially isolated group increased the odds of abnormal ADL, IADL, and functional mobility by 105-150%, and decreased the overall health score by 5.30 (3.42, 7.18). Conclusion: We demonstrated the association of social isolation with poorer physical function and mental health and overall health status among the community-dwelling Chinese older adults living with homecare services. These findings provided new knowledge about the association of social isolation with both physical and mental function for daily living even for those receiving an integrated homecare service in the community. It implies that an unmet healthcare need existed when comparing the service scope of the current homecare services in the community. It also highlighted the need for targeted prevention and intervention initiatives among community-dwelling old adults to alleviate social isolation for better health and good functioning in the community.

Preoperative Dehydration Increases the Risk of Extended Length of Hospital Stay Following Total Ankle Arthroplasty.

INTRODUCTION: The effects of preoperative dehydration on outcomes following total ankle arthroplasty (TAA) remain unknown. Therefore, the purpose of this study is to evaluate the association between dehydration and postoperative complications for patients undergoing TAA. METHODS: Patients undergoing TAA from 2007 to 2019 were identified in the National Surgical Quality Improvement Program (NSQIP) database. A preoperative serum blood urea nitrogen/creatinine (BUN/Cr) greater than 20 was used to define preoperative dehydration. Patients were stratified into 2 cohorts: patients who were dehydrated (BUN/Cr > 20) and patients without dehydration (BUN/Cr ≤ 20). In this analysis, various postoperative outcomes were assessed with bivariate and multivariate analyses. RESULTS: In total, 1033 patients underwent TAA and had their serum BUN and Cr values recorded. For both BUN and Cr, the patients in this study had their serum values recorded a mean of 15 days before their surgery. A total of 588 patients (56.9%) did not have dehydration preoperatively and 445 patients (43.1%) were dehydrated. Following adjustment on multivariate analysis, an increased risk of extended length of hospital stay (odds ratio [OR] = 1.457; p = 0.024) was seen in the dehydrated group compared with those who were noted to be well hydrated. CONCLUSION: As fluid intake is one modifiable preoperative variable that can be easily monitored during elective procedures, it is important for physicians to be aware of patients who are dehydrated and adjust their fluids appropriately to optimize postoperative outcomes. LEVELS OF EVIDENCE: Level III: Retrospective cohort study.

Risks of Immunosuppressive Therapy in Patients Undergoing Open Reduction Internal Fixation for Ankle Fractures.

Chronic steroid and immunosuppressant use have been shown to increase the risk for postoperative complications in orthopedic surgery. Further understanding of the risks of immunosuppression is necessary to aid in risk stratification and patient counseling. However, these risks have not yet been explored in ankle fracture patients. Thus, the purpose of this study is to determine whether patients taking immunosuppressives are at an increased risk for morbidity and mortality following open reduction and internal fixation (ORIF) of ankle fractures. Patients undergoing operative treatment for ankle fractures from 2006 to 2018 were identified in the National Surgical Quality Improvement Program database. Patients were categorized based on their use of immunosuppressive medications. Postoperative outcomes assessed included superficial surgical site infections, deep surgical site infections, organ space infections, wound dehiscence, pneumonia, unplanned intubation, pulmonary embolism, urinary tract infection, renal failure, blood transfusion requirement, deep vein thrombosis, sepsis, cardiac arrest, extended length of hospital stay, readmission, reoperation, and mortality. Univariate and multivariate analyses were performed. In total, 10,331 patients underwent operative treatment for ankle fracture. Total 10,153 patients (98.3%) were not taking immunosuppressants and 178 (1.7%) were taking these medications. In multivariate analysis, patients taking immunosuppressants were at increased risk of pulmonary embolism (odds ratio [OR] 4.382; p = .041) and hospital readmission (OR 2.131; p = .021). Use of immunosuppressive medications is an independent risk factor for pulmonary embolism and readmission following ORIF for ankle fractures. Notably, no association with wound complications, infections, or sepsis was identified.

Psychosocial Burden of Pediatric and Adult Patients With Congenital Versus Traumatic Facial Differences: Assessment of Psychiatric Distress and Healthcare Utilization in the United States From 2004 to 2012.

BACKGROUND: Psychiatric distress and its effects on healthcare utilization in pediatric patients with congenital and traumatic facial differences remain poorly understood. This study analyzes the psychosocial burden along with mental health and reconstructive surgery services utilization of this patient population in comparison with adult patients with such facial differences. METHODS: The 2004-2012 Medical Expenditures Panel Survey was queried for all patients with facial differences. Socioeconomic variables, Patient Health Questionnaire 2 and Kessler 6 scores, responses from validated screening surveys, and utilization of mental health and reconstructive surgery (ie, plastic surgery and otolaryngology) services were compared between pediatric and adult patients with congenital and traumatic facial differences. RESULTS: Children ages 5 to 12 years were more likely to be affected by facial trauma, whereas adolescents aged 13 to 17 years were more affected by congenital facial conditions. Pediatric patients with congenital facial conditions had higher rates of medical care, education, and special therapy utilization ( P < 0.0001), although their facial trauma counterparts used mental health services more often ( P < 0.0001). In adults, more facial trauma patients reported poorer perceived mental health status ( P = 0.01). Among patients with any facial difference, distressed adult patients were less likely to see a reconstructive surgeon even when controlling for socioeconomic variables (0.55 [0.31-0.97], P = 0.04). CONCLUSIONS: In the pediatric population, psychosocial considerations should include both age and etiology of facial differences to best optimize care. Among adults with facial trauma, poor mental health may contribute to lower rates of surgical follow-up, highlighting a potential benefit for provision of mental health services earlier for these patient populations.

The association between anesthesia type and postoperative outcomes in patients receiving primary total shoulder arthroplasty.

PURPOSE: There has been interest to investigate optimal anesthetic techniques for primary total shoulder arthroplasty (TSA). In this study, we investigate if there are differences in postoperative complications in patients receiving (1) regional alone; (2) general alone; and (3) regional plus general anesthesia for primary TSA. METHODS: Patients undergoing primary TSA from 2014 to 2018 were identified in a national database. Patients were stratified into 3 cohorts: general anesthesia, regional anesthesia, and general anesthesia combined with regional anesthesia. Thirty-day complications were assessed using bivariate and multivariate analyses. RESULTS: Of 13,386 total patients undergoing TSA, 9079 patients (67.8%) had general anesthesia, 212 (1.6%) had regional anesthesia, and 4095 (30.6%) had general anesthesia combined with regional anesthesia. There were no significant differences in postoperative complications between the general anesthesia group and the regional anesthesia group. Following adjustment, an increased risk of extended length of hospital stay was seen in the combined general and regional anesthesia group compared to those who only had general anesthesia (p = 0.001). CONCLUSION: General versus regional versus general plus regional anesthesia have no difference in postoperative complications in patients receiving primary total shoulder arthroplasty. However, addition of regional anesthesia to general anesthesia is associated with increased length of stay. LEVEL OF EVIDENCE: III.

Simultaneous treatment of two lung cancer lesions with stereotactic MR-guided adaptive radiation therapy: A case report.

RATIONALE: Lung cancer is 1 of the most prevalent cancers globally. Definitive stereotactic ablative radiotherapy (SABR) is suggested for those who are unfit for or refuse surgical intervention. Here we present a patient with 2 lung cancer lesions who received SABR simultaneously with magnetic resonance Linear accelerator (Linac)-magnetic resonance (MR). PATIENT CONCERNS: A 46-years-old man had history of left lower lung cancer post lobectomy in 2018. Two recurrent tumors were found 2 years following, then became enlarged 4 months later. DIAGNOSES: The recurrent tumors were found by computed tomography. INTERVENTIONS: SABR was indicated due to inoperability and small size. Simulation was done both by computed tomography and MR scan with ViewRay MRIdian Linac, with the prescription dose being 50 gray in 4 fractions performed every other day within 2 weeks. The 2 lesions were irradiated at the same time with a single isocenter with mean treatment time was 78 minutes. OUTCOMES: No acute side effect was noted. Follow-up chest computed tomography scan 14 months after SABR showed mild consolidation and pneumonitis over the upper irradiated site favoring radiation-related reasons, while pneumonitis was resolved over the lower irradiated site. Positron emission tomography showed no definite evidence of FDG-avid recurrence. The patient has survived over 18 months following SABR and more than 4 years from the first diagnosis of lung cancer without significant adverse effects. LESSONS: Simultaneous SABR for multiple lung lesions is quite challenging because tumor motion by breathing can increase the risk of missing the target. With help by MR-Linac, simultaneous SABR to multiple lung lesions can be performed safely with efficacy.

A hybrid machine learning framework to improve prediction of all-cause rehospitalization among elderly patients in Hong Kong.

BACKGROUND: Accurately estimating elderly patients' rehospitalisation risk benefits clinical decisions and service planning. However, research in rehospitalisation and repeated hospitalisation yielded only models with modest performance, and the model performance deteriorates rapidly as the prediction timeframe expands beyond 28 days and for older participants. METHODS: A temporal zero-inflated Poisson (tZIP) regression model was developed and validated retrospectively and prospectively. The data of the electronic health records (EHRs) contain cohorts (aged 60+) in a major public hospital in Hong Kong. Two temporal offset functions accounted for the associations between exposure time and parameters corresponding to the zero-inflated logistic component and the Poisson distribution's expected count. tZIP was externally validated with a retrospective cohort's rehospitalisation events up to 12 months after the discharge date. Subsequently, tZIP was validated prospectively after piloting its implementation at the study hospital. Patients discharged within the pilot period were tagged, and the proposed model's prediction of their rehospitalisation was verified monthly. Using a hybrid machine learning (ML) approach, the tZIP-based risk estimator's marginal effect on 28-day rehospitalisation was further validated, competing with other factors representing different post-acute and clinical statuses. RESULTS: The tZIP prediction of rehospitalisation from 28 days to 365 days was achieved at above 80% discrimination accuracy retrospectively and prospectively in two out-of-sample cohorts. With a large margin, it outperformed the Cox proportional and linear models built with the same predictors. The hybrid ML revealed that the risk estimator's contribution to 28-day rehospitalisation outweighed other features relevant to service utilisation and clinical status. CONCLUSIONS: A novel rehospitalisation risk model was introduced, and its risk estimators, whose importance outweighed all other factors of diverse post-acute care and clinical conditions, were derived. The proposed approach relies on four easily accessible variables easily extracted from EHR. Thus, clinicians could visualise patients' rehospitalisation risk from 28 days to 365 days after discharge and screen high-risk older patients for follow-up care at the proper time.

The Effects of Chronic Steroid Use on Postoperative Complications Following Thyroidectomy.

BACKGROUND: Patients undergoing thyroidectomy are sometimes on chronic steroids for underlying disease. This study examined the postoperative risk profile of thyroidectomy patients on chronic steroids. METHODS: Patients in the National Surgical Quality Improvement Program (NSQIP) database who underwent thyroidectomy were sorted by presence or absence of chronic steroid use. Clinicodemographics, comorbidities, and postoperative complications were recorded and compared between the two. Univariate and multivariate analyses compared the groups and calculated odds ratios (OR). RESULTS: We identified 42,857 patients. 41,903 (97.8%) patients were not on chronic steroids, while 954 (2.2%) were. Most underwent total thyroidectomy (18,748, 43.75%) or total lobectomy (16,323, 38.09%). Following univariate and multivariate analyses, patients on chronic steroids had increased risk of postoperative bleeding and transfusions (OR = 0.375, p = 0.046, 95% CI 0.223-0.988), open wound infection (OR = 0.226, p < 0.001, 95% CI 0.117-0.437), pulmonary embolism (OR = 0.312, p = 0.034, 95% CI 0.106-0.918), and ventilator use > 48 h (OR = 0.401, p < 0.008, 95% CI 0.205-0.785). CONCLUSIONS: Chronic steroid use prior to thyroidectomy is an independent risk factor for multiple postoperative complications, namely postoperative bleeding and transfusions, open wound infection, pulmonary embolism, and ventilator use over 48 h. Patients on chronic steroids should be medically optimized before thyroidectomy to reduce the risk of potentially life-threatening complications.

Evaluating the association between pulmonary abnormalities and complications following pediatric hip dysplasia surgery.

PURPOSE: Developmental dysplasia of the hip (DDH) encompasses a wide range of abnormal hip development and is a common condition in the pediatric population. Congenital pulmonary abnormalities are typically mild in the pediatric population but can be associated with severe comorbid conditions. The purpose of this study was to analyze the effect of structural pulmonary/airway abnormalities on the incidence of postoperative complications following surgical management of DDH. METHODS: From 2012 to 2019, the National Surgical Quality Improvement Program-Pediatric database was utilized to identify pediatric patients undergoing surgical treatment for hip dysplasia. Patients were stratified into two groups: patients with a structural pulmonary/airway abnormality and patients without a pulmonary abnormality. Patient demographics, comorbidities, and postoperative complications were compared between the two cohorts with the use of various statistical analyses, including bivariate and multivariate analyses. RESULTS: Of the 10,853 patients who underwent surgical treatment for hip dysplasia, 10,157 patients (93.6%) did not have a structural pulmonary/airway abnormality whereas 696 (6.4%) had an airway abnormality. Following adjustment on multivariate analysis, patients with a structural pulmonary abnormality had an increased risk of cardiac arrest requiring cardiopulmonary resuscitation (OR 2.342; p = 0.045). CONCLUSION: The results indicated that patients with a structural pulmonary abnormality had an increased risk of cardiac arrest requiring cardiopulmonary resuscitation compared to those without a pulmonary abnormality. Ensuring appropriate preoperative evaluation with a multidisciplinary team and close monitoring postoperatively is important to prevent the risk of severe outcomes in this vulnerable patient population.

Boston Carpal Tunnel Questionnaire Scores Alone Do Not Predict Surgical Intervention for Patients With Carpal Tunnel Syndrome.

BACKGROUND: With the expanded indications for telemedicine, there is increased utility for screening methods to determine which patients are likely to progress to surgical intervention, requiring in-person visits. Patient-rated tools such as the Boston Carpal Tunnel Questionnaire (BCTQ) may be one such tool for screening patients with carpal tunnel syndrome (CTS). The aim of the study was to evaluate whether BCTQ scores were predictive of offering conservative treatment or surgical intervention for CTS. METHODS: Patients diagnosed with CTS from January 2017 to February 2020 completed BCTQ questionnaires prior to in-person office visits. Demographics, comorbidities, and highest level of intervention recommended were recorded for each patient as conservative, injection, or surgery. Pearson χ2 and independent-samples t tests were conducted to determine whether BCTQ symptom severity and functional scores were associated with intervention type. RESULTS: A total of 200 patients with CTS were included. Of these, 103 were recommended conservative or injection treatment and 97 were recommended surgery. There were no differences in comorbidities between groups, including other upper extremity pathology (P = .57), previous upper extremity surgery (P = .32), hypertension (P = .17), hypothyroidism (P = .15), rheumatoid arthritis (P = .34), and diabetes (P = .30). Between these groups, there were no differences in BCTQ symptom severity score (symptom severity scale [SSS]; P = .16) or BCTQ functional severity score (functional severity scale [FSS]; P = .96). CONCLUSIONS: There is no correlation between comorbidities and BCTQ SSS or FSS score, and offering surgery for CTS. In an era of minimizing non-essential health care visits, the BCTQ is insufficient in screening patients as potential surgical candidates.

Is seizure disorder a risk factor for complications following surgical treatment of hip dysplasia in the pediatric population?

The impact of seizure disorders on pediatric patients who undergo hip dysplasia surgery has yet to be elucidated. This study focused on identifying the effect of seizure disorders on the incidence of complications following surgical management of hip dysplasia. Pediatric patients undergoing surgical treatment for hip dysplasia from 2012 to 2019 were identified in the National Surgical Quality Improvement Program-Pediatric database. Patients were divided into two cohorts: patients with and patients without a seizure disorder. Patient demographics, comorbidities and postoperative outcomes were compared between the two groups. Bivariate and multivariate analyses were performed. Of 10 853 pediatric patients who underwent hip dysplasia surgery, 8117 patients (74.8%) did not have a seizure disorder whereas 2736 (25.2%) had a seizure disorder. Bivariate analyses revealed that compared to patients without a seizure disorder, patients with a seizure disorder were at increased risk of developing surgical site infections, pneumonia, unplanned reintubation, urinary tract infection, postoperative transfusion, sepsis, extended operation time and length of stay and readmission ( P < 0.05 for all). Following adjustment for patient demographics and comorbidities on multivariate analysis, there were no differences in any postoperative complications between pediatric patients with and without a seizure disorder. There were no differences in 30-day postoperative complications in patients with and without a seizure disorder. Due to potential decreased bone mineral density as an effect of antiepileptic drugs and the risk of femur fracture during surgery for hip dysplasia, pediatric patients with a seizure disorder should be closely monitored as they may be more susceptible to injury. Level of Evidence: III.

The association between diabetes status and postoperative complications for patients receiving ACL reconstruction.

PURPOSE: It is well established that diabetes is associated with complications following surgical procedures across the wide array of surgical subspecialties. The evidence on the effect of diabetes on postoperative outcomes following anterior cruciate ligament (ACL) reconstruction (ACLR), however, is not as robust, and findings have not been consistent. It was hypothesized that patients with diabetes are at increased risk of complications and a higher rate of hospital admission following ACLR. METHODS: The National Surgical Quality Improvement Program database was queried for patients undergoing ACL reconstruction from 2006 to 2019. Two patient cohorts were defined in this retrospective study: patients with diabetes and patients without diabetes. The various patient demographics, medical comorbidities, and postoperative outcomes were compared between the two groups, with the use of bivariate and multivariate analyses. RESULTS: Of 9,576 patients who underwent ACL reconstruction, 9,443 patients (98.6%) did not have diabetes, whereas 133 patients (1.4%) had diabetes. Following adjustment on multivariate analyses, compared to non-diabetic patients, those with diabetes had an increased risk of admission to the hospital within thirty days of the surgery (OR 2.14; p = 0.002). CONCLUSION: Patients with diabetes have a significantly higher risk of being admitted to the hospital compared to those without the disease. Clinicians should be aware of diabetic patients who undergo ACLR to ensure appropriate pre- and postoperative care to minimize complications in this patient population.
