Repurposing chemotherapy-induced peripheral neuropathy grading.

BACKGROUND AND PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is perceived differently by patients and physicians, complicating its assessment. Current recommendations advocate combining clinical and patient-reported outcomes measures, but this approach can be challenging in patient care. This multicenter European study aims to bridge the gap between patients' perceptions and neurological impairments by aligning both perspectives to improve treatment decision-making. METHODS: Data were pooled from two prospective studies of subjects (n = 372) with established CIPN. Patient and physician views regarding CIPN were assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), Total Neuropathy Scale-clinical version (TNSc) items, and the disease-specific quality of life - Chemotherapy-Induced Peripheral Neuropathy questionnaire (QLQ-CIPN20) from the European Organization for Research and Treatment of Cancer (EORTC). To identify inherent neurotoxic severity patterns, we employed hierarchical cluster analysis optimized with k-means clustering and internally validated by discriminant functional analysis. RESULTS: Both NCI-CTCAE and TNSc demonstrated a significant difference in the distribution of severity grades in relation to QLQ-CIPN20 scores. However, a proportion of subjects with different neurotoxic severity grades exhibited overlapping QLQ-CIPN20 scores. We identified three distinct clusters classifying subjects as having severely impaired, intermediately impaired, and mildly impaired CIPN based on TNSc and QLQ-CIPN20 scores. No differences in demographics, cancer type distribution, or class of drug received were observed. CONCLUSIONS: Our results confirm the heterogeneity in CIPN perception between patients and physicians and identify three well-differentiated subgroups of patients delineated by degree of CIPN impairment based on scores derived from TNSc and QLQ-CIPN20. A more refined assessment of CIPN could potentially be achieved using the calculator tool derived from the cluster equations in this study. This tool, which facilitates individual patient classification, requires prospective validation.

Neurological functional outcome of early versus delayed cranioplasty following decompressive craniectomy at a tertiary care centre.

Cranioplasty performed after a decompressive craniectomy (DC) for traumatic brain injury (TBI), stroke, or aneurysmal bleed has a role of restoring cerebral protection and craniofacial cosmesis as well as improving neuromotor function. There has been no consensus with regards to the ideal timing of cranioplasty (CP) after DC. A retrospective cohort study was carried out at a tertiary care hospital on patients who had undergone early (less than or equal to 12 weeks) and late (greater than 12 weeks) cranioplasty using autologous cranial bone after DC. Functional independence measure (FIM) tools were used to compare neuromotor and cognitive function outcome between the two groups. Appropriate statistical tools were used to compare neuromotor and cognitive function improvement as well as complication rates between early and late cranioplasty. A total of 31 adult patients of cranioplasty (21 male and 10 female) were evaluated. Sixteen had undergone early and 15 late cranioplasty. Comparison for neuromotor and cognitive function using FIM tools revealed statistically significant neuromotor and cognitive advantages in the early cranioplasty group. Overall complication rates between the two groups varied but were statistically insignificant. Performing an early cranioplasty provides advantages of improvement of neuromotor and cognitive function through early restoration of cerebrospinal fluid and intracerebral haemo-dynamics. It further avoids the potential problems of developing the 'Syndrome of the Trephined' (otherwise known as sinking skin flap syndrome) and resorption of the autologous bone.

Total Hip Arthroplasty Patients Who Have Ostomies Have an Increased Risk of Revisions for Periprosthetic Joint Infection, But Total Knee Arthroplasty Patients Do Not.

INTRODUCTION: Patient comorbidities can lead to worse outcomes and increase the risk of revisions after total hip (THA) and total knee arthroplasty (TKA). Sparse research is available on the effects of ostomies on postoperative outcomes. Our study aimed to assess whether patients who have ostomies who underwent TKA or THA have worse outcomes and increased rates of all-cause and periprosthetic joint infection (PJI) -related revisions. METHODS: We performed a retrospective cohort study comparing the outcomes of THA and TKA patients who have and do not have a history of ostomy using the Statewide Planning and Research Cooperative System. Patient demographics, ostomy diagnosis, 3-month emergency department visits and readmissions, and revisions were collected. A total of 126,414 THA and 216,037 TKA cases were included. Log-rank testing and a Cox proportional hazards model were used to account for covariates. RESULTS: In total, 463 THA patients (0.4%) had ostomies. They had a longer length of stay (LOS) (4.0 versus 3.1 days, P < 0.001) and were less likely to be discharged home (55.3 versus 62.2%). They had higher rates of PJI-related revisions (1.9 versus 0.9%, P = 0.02) and had increased odds of PJI-related revision (OR [odds ratio] = 2.2, P = 0.02). Of TKA patients, 619 patients (0.3%) had an ostomy. They had a longer LOS (3.6 versus 3.3 days, P = 0.02) and was less likely to be discharged home (49.4 versus 52.4%, P = 0.16). However, there was no difference in the rate (1.8 versus 1.4%, P = 0.49) or odds (OR = 1.2, P = 0.53) of PJI-related revision. CONCLUSION: Total hip arthroplasty, but not TKA, patients who have ostomies have an increased risk of PJI-related revisions. The proximity of the surgical incision to the ostomy site may play a role in the risk of PJI in THA patients.

Outpatient vs. inpatient designation in total hip arthroplasty: can we predict who will require hospitalization?

INTRODUCTION: Following removal of total hip arthroplasty (THA) from the inpatient only (IPO) list by the Center for Medicare Services (CMS), arthroplasty surgeons face increased pressure to perform procedures on an outpatient (OP) basis. The purposes of the present study were to compare patients booked for THA as OP who required conversion to IP status postoperatively, to patients who were booked as, and remained OP, and to identify factors predictive of conversion from OP to IP status. METHODS: We retrospectively reviewed all patients who underwent a primary THA at our institution between January 1, 2020 and April 26, 2022. All patients included were originally scheduled for OP surgery and were separated based on conversion to IP status postoperatively. Multiple regression analyses were used to determine the significance of all perioperative variables. Modeling via binary logistic regressions were used to determine factors predictive of status conversion. RESULTS: Of 1,937 patients, 372 (19.2%) designated as OP preoperatively required conversion to IP status postoperatively. These patients had significantly higher facility discharge rates (P < 0.001) and 90-day readmission rates (P = 0.024). Patients aged 65 and older (P < 0.001), females (P < 0.001), patients with Black/African American race (P = 0.027), with a recovery room arrival time after 12 pm (P < 0.001), with a BMI > 30 kg/m2 (P = 0.001), and with a Charlson Comorbidity Index (CCI) ≥ 4 (P = 0.013) were Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation more likely to require conversion to IP designation. Marital status and time of procedure were also significant factors, as patients who were married (P < 0.001) and who were the first case of the day (P < 0.001) were less likely to be converted to IP. CONCLUSION: Several factors were identified which could help determine appropriate hospital designation status at the time of surgical booking to ultimately avoid insurance claim denials. These included BMI, certain demographic factors, CCI ≥ 4, and patients 65 or older. LEVEL III EVIDENCE: Retrospective Cohort Study.

Clinical outcomes of total joint arthroplasty in patients with bowel ostomies.

INTRODUCTION: The influence of prior colostomy or ileostomy on patients undergoing joint arthroplasty remains poorly understood. Our study aimed to assess whether patients with an ostomy undergoing hip and knee arthroplasties have worse postoperative outcomes and increased rates of revisions. METHOD: A single-center, retrospective review of patients with a history of bowel ostomy who underwent a primary total hip arthroplasty (THA), hemiarthroplasty (HA), and total knee arthroplasty (TKA) from 2012 to 2021. A total of 24 THAs, 11 HAs, and 25 TKAs in patients with open small or large bowel stoma were identified. A ten-to-one propensity score match was utilized to establish cohorts with comparable demographics but no prior ostomy procedure. RESULTS: Patients with stomas undergoing elective THA showed greater 90-day ED visits (20.0 vs. 5.0%, P = 0.009), 90-day all-cause readmissions (20.0 vs. 5.0%, P = 0.009), 90-day non-orthopedic readmissions (10.0 vs. 0.5%, P < 0.001), 90-day readmissions for infection (5.0 vs. 0.5%, P = 0.043), all-cause revisions (15.0 vs. 0.5%, P < 0.001), revisions for PJI (5.0 vs. 0%, P = 0.043), and revisions for peri-prosthetic fracture (10.0 vs. 0%, P < 0.001). Patients with stomas undergoing non-elective hip arthroplasties exhibited a longer mean LOS (12.1 vs. 7.0 days, P < 0.001) and increased 90-day all-cause readmissions (40.0 vs. 17.3%, P = 0.034), 90-day orthopedic readmissions (26.7 vs. 6.0%, P = 0.005), all-cause revisions (13.3 vs. 2.0%, P = 0.015), revisions for peri-prosthetic fracture (6.7 vs. 0%, P = 0.002), and revisions for aseptic loosening (6.7 vs. 0%, P = 0.002). There were no significant differences in readmission or revision rates between ostomy patients undergoing TKA and a matched control group. CONCLUSION: Patients undergoing hip arthroplasties with an open stoma are at an increased risk of hospital encounters and revisions, whereas TKA patients with stomas are not at increased risk of complications. These findings emphasize the importance of recognizing and addressing the unique challenges associated with this patient population.

Patient Demographic Factors Affect Response Rates to Patient-Reported Outcome Measures for Total Hip Arthroplasty Patients.

BACKGROUND: The Hip Disability and Osteoarthritis Outcome Score (HOOS JR) is a widely used patient-reported outcome measures questionnaire for total hip arthroplasty (THA). However, not all patients choose to complete HOOS JR, and thus, a subset of the THA population may be underrepresented. This study aims to investigate the association between patient demographic factors and HOOS JR response rates. METHODS: This was a retrospective cohort study of adult, English-speaking patients who underwent primary THA by a fellowship-trained arthroplasty surgeon between 2017 and 2023 at a single, high-volume academic institution. The HOOS JR completion status-complete or incomplete-was recorded for each patient within 90 days of surgery. Standard statistical analyses were performed to assess completion against multiple patient demographic factors. RESULTS: Of the 2,908 total patients, 2,112 (72.6%) had complete and 796 (27.4%) had incomplete HOOS JR questionnaires. Multivariate analysis yielded statistical significance (P < .05) for the distribution of patient age, race, insurance, marital status, and income quartile with respect to questionnaire completion. Patient sex or religion did not affect response rates. Failure to complete HOOS JR (all P < .001) was associated with patients aged 18 to 39 (59.8%), who identified as Black (36.4%) or "other" race (39.6%), were never married (38%), and were in the lower half income quartiles (43.9%, 35.9%) when compared to the overall incomplete rate. CONCLUSIONS: Multiple patient demographic factors may affect the HOOS JR response rate. Overall, our analyses suggest that older patients who identify as White and are of higher socioeconomic status are more likely to participate in the questionnaire. Efforts should focus on capturing patient groups less likely to participate to elucidate more generalizable trends in arthroplasty outcomes.

Comparison of Two Previously Validated Risk Assessment and Prediction Tool Models in Extended Length of Stay Patients Following total Hip Arthroplasty.

INTRODUCTION: Previous studies have attempted to validate the risk assessment and prediction tool (RAPT) in primary total hip arthroplasty (THA) patients. The purpose of this study was to: (1) identify patients who had an extended length of stay (LOS) following THA; and (2) compare the accuracy of 2 previously validated RAPT models. METHODS: We retrospectively reviewed all primary THA patients from 2014 to 2021 who had a completed RAPT score. Youden's J computational analysis was used to determine the LOS where facility discharge was statistically more likely. Based on the cut-offs proposed by Oldmeadow and Dibra, patients were separated into high- (O: 1 to 5 versus D: 1 to 3), medium- (O: 6 to 9 versus D: 4 to 7), and low- (O: 10 to 12 versus D: 8 to 12) risk groups. RESULTS: We determined that an LOS of greater than 2 days resulted in a higher chance of facility discharge. In these patients (n = 717), the overall predictive accuracy (PA) of the RAPT was 79.8%. The Dibra model had a higher PA in the high-risk group (D: 68.2 versus O: 61.2% facility discharge). The Oldmeadow model had a higher PA in the medium-risk (O: 78.7 versus D: 61.4% home discharge) and low-risk (O: 97.0 versus D. 92.5% home discharge) groups. CONCLUSIONS: As institutions continue to optimize LOS, the RAPT may need to be defined in the context of a patient's hospital stay. In patients requiring an LOS of greater than 2 days, the originally established RAPT cut-offs may be more accurate in predicting discharge disposition. LEVEL OF EVIDENCE: III Retrospective Cohort Study.

Management Modalities of Aggressive Brown Tumor of the Jaws-a Case Series.

Primary hyperparathyroidism is an endocrine disorder occurring due to increased secretion of parathormone resulting in clinical, anatomical, and biochemical alterations. On the other hand, excision of a parathyroid adenoma can normalize the metabolic status. Brown tumors represent the terminal stage of the remodeling processes during primary or secondary hyperparathyroidism. They are erosive bony lesions caused by rapid osteolysis and peritrabecular fibrosis, resulting in a local destructive phenomenon. Facial skeleton is involved in about 2% of all cases of which the mandible is frequently affected. We report a case series of four patients who presented with brown tumor of both maxilla and mandible. A complete assessment of the medical history, blood investigations and radiological findings combined with biopsy results is necessary for a correct diagnosis. The standard treatment of the Brown tumors is not a surgical resection, but the treatment of the cause of the tumor, which in this case is hyperparathyroidism. However in our case, the extent of the lesion and the non resolution after the parathyroidectomy necessitated a surgical approach in two of our patients however two responded well to medical management alone.

How Has the Total Hip Arthroplasty Patient Population Changed? A Ten-Year Analysis of Total Hip Arthroplasty Patients From 2013 to 2022: A Retrospective, Single-Center Study.

BACKGROUND: Over the past decades, utilization of total hip arthroplasty (THA) has steadily increased. Understanding the demographic trends of THA patients can assist in projecting access to care. This study sought to assess the temporal trends in THA patient baseline characteristics and socioeconomic factors. METHODS: We retrospectively analyzed 16,296 patients who underwent primary elective THA from January 1, 2013, to December 31, 2022. Demographic data, including age, sex, race, body mass index (BMI), Charlson comorbidity index, insurance, and socioeconomic status, as determined by median income by patients' zip code, were collected. The trends of these data were analyzed using the Mann-Kendall test. RESULTS: Over the past decade at our institution, patient age (2013: 62.1 years to 2022: 65.1 years, P = .001), BMI (2013: 29.0 to 2022: 29.5, P = .020), and mean Charlson comorbidity index (2013: 2.4 to 2022: 3.1, P = .001) increased. The proportion of Medicare patients increased from 48.4% in 2013 to 54.9% in 2022 (P = .001). The proportion of African American patients among the THA population increased from 11.3% in 2013 to 13.0% in 2022 (P = .012). Over this period, 90-day readmission and 1-year revision rates did not significantly change (2013: 4.8 and 3.0% to 2022: 3.4 and 1.4%, P = .107 and P = .136, respectively). The proportion of operations using robotic devices also significantly increased (2013: 0% to 2022: 19.1%; P < .001). CONCLUSIONS: In the past decade, the average age, BMI, and comorbidity burden of THA patients have significantly increased, suggesting improved access to care for these populations. Similarly, there have been improvements in access to care for African American patients. Along with these changes in patient demographics, we found no change in 90-day readmission or 1-year revision rates. Continued characterization of the THA patient population is vital to understanding this demographic shift and educating future strategies and improvements in patient care.

Hormone Receptor Expression and Activity for Different Tumour Locations in Patients with Advanced and Recurrent Endometrial Carcinoma.

BACKGROUND: Response to hormonal therapy in advanced and recurrent endometrial cancer (EC) can be predicted by oestrogen and progesterone receptor immunohistochemical (ER/PR-IHC) expression, with response rates of 60% in PR-IHC > 50% cases. ER/PR-IHC can vary by tumour location and is frequently lost with tumour progression. Therefore, we explored the relationship between ER/PR-IHC expression and tumour location in EC. METHODS: Pre-treatment tumour biopsies from 6 different sites of 80 cases treated with hormonal therapy were analysed for ER/PR-IHC expression and classified into categories 0-10%, 10-50%, and >50%. The ER pathway activity score (ERPAS) was determined based on mRNA levels of ER-related target genes, reflecting the actual activity of the ER receptor. RESULTS: There was a trend towards lower PR-IHC (33% had PR > 50%) and ERPAS (27% had ERPAS > 15) in lymphogenic metastases compared to other locations (p = 0.074). Hematogenous and intra-abdominal metastases appeared to have high ER/PR-IHC and ERPAS (85% and 89% ER-IHC > 50%; 64% and 78% PR-IHC > 50%; 60% and 71% ERPAS > 15, not significant). Tumour grade and previous radiotherapy did not affect ER/PR-IHC or ERPAS. CONCLUSIONS: A trend towards lower PR-IHC and ERPAS was observed in lymphogenic sites. Verification in larger cohorts is needed to confirm these findings, which may have implications for the use of hormonal therapy in the future.
