Functionality, complications, and survivorship of total shoulder arthroplasty in patients under 60 years old

Background

As total shoulder arthroplasty (TSA) expands to younger patients, it is crucial to weigh the benefits of early intervention against potential complications and implant longevity in patients under 60 years of age. This study examines mid-term outcomes in this patient subset.

Methods

Between 2009 and 2019, a retrospective analysis was conducted on 50 patients (25 male, 25 female) who underwent anatomic TSA (TSA) under the age of 60 with minimum 5 years follow-up. Demographic and baseline variables were extracted from medical records. Pre-operative and post-operative outcomes of range of motion (ROM) and strength were recorded. Patient-reported outcomes (PROs) were obtained.

Results

Fifty patients were followed for an average of 8.7 ± 2.4 years, having a mean age of 54.1 ± 8.4 years. Comparison of pre-operative and post-operative measurements revealed significant improvements in active ROM, including external rotation (ER) (p < 0.0001), forward elevation (FE) (p < 0.0001), and internal rotation (IR) (p = 0.0001). There were significant improvements in functional strength scores, including ER (p = 0.0005) and FE (p = 0.0002). PROs included visual analog scale (VAS) (2.2 ± 2.6), Single Assessment Numeric Evaluation (SANE) (80.3 ± 17.6), American Shoulder and Elbow Surgeons (ASES) score (76.4 ± 22.8), and Simple Shoulder Test (SST) (8.9 ± 3.2). The 5-year and 10-year implant survival rates were found to be 98.0 % and 83.3 %, respectively. There were 7 postoperative complications in 5 patients (14.0 %), including glenoid loosening (n = 2), infection (n = 1), atraumatic instability (n = 1), lesser tuberosity avulsion (n = 1), painful arthroplasty (n = 1) and traumatic rotator cuff insufficiency (n = 1). Subsequently, all 5 patients underwent revision shoulder arthroplasty at an average of 6.5 years after the initial procedure.

Conclusion

Positive mid to long-term outcomes, including significant improvements in ROM and strength, along with high 5-year and 10-year implant survival rates support TSA as an effective treatment option for patients under the age of 60.

Modified R-BAC plus BTK inhibitor regimen in newly diagnosed young patients with mantle cell lymphoma: a real-world retrospective study

To explore the optimal treatment for young patients with untreated mantle cell lymphoma (MCL), we compared the efficacy and safety of R-CHOP/R-DHAP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone/rituximab, dexamethasone, cytarabine and cisplatin) and R-BAP (rituximab, bendamustine, cytarabine, and prednisone) plus BTK (Bruton's tyrosine kinase) inhibitors in newly diagnosed patients. Eighty-three young patients (≤ 65 years old) with newly diagnosed MCL admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2014, to June 1, 2023, using R-CHOP/R-DHAP or R-BAP plus BTK inhibitor were assessed in this study. The median age at presentation was 60 (42-65) years in 83 patients, including 64 males and 19 females; 59 were treated with R-CHOP/R-DHAP regimen chemotherapy, and 24 were treated with R-BAP in combination with the BTK inhibitor regimen. The median follow-up was 17 months (2-86 months) in 83 patients, and the median PFS (progression-free survival) time was not reached. The CRR (complete response rate) of the R-BAP group was higher than that of the R-CHOP/R-DHAP group (87.5% vs. 54.2%, P = 0.005). The ORR (overall response rate) was not significantly different between the two groups (ORR: 91.7% vs. 84.7%, P = 0.497). The PFS (progression-free survival) of the R-BAP group was longer than that of the R-CHOP/R-DHAP group (P = 0.013), whereas OS was not significantly different between the two groups (P = 0.499). The most common adverse effect in both groups was hematotoxicity, with a higher incidence of grade 3-4 lymphopenia and grade 3-4 thrombocytopenia in the R-BAP group than in the R-CHOP/R-DHAP group (P = 0.015 and P = 0.039). Male sex (HR = 4.257, P = 0.013), LDH (lactate dehydrogenase) ≥ 245 U/L (HR = 3.221, P = 0.012), pleomorphic-blastoid (HR = 2.802, P = 0.043) and R-CHOP/R-DHAP regimen (HR = 7.704, P = 0.047) were independent risk factors for PFS. Ki67 ≥ 30% (HR = 8.539, P = 0.005) was an independent risk factor for OS. First-line treatment with R-BAP in combination with BTK inhibitor improved CRR and prolonged PFS in young patients with mantle cell lymphoma and adverse events were tolerable.

Long-term outcomes of the mayo conservative hip system in patients aged 30 years or less with osteonecrosis of the femoral head: mean follow-up of more than 10 years

INTRODUCTION

Historically, total hip arthroplasty (THA) in very young patients has been associated with lower survivorship. However, the long-term outcomes of THA using short stems for osteonecrosis of the femoral head (ONFH) in very young patients remain unclear. Therefore, this study aimed to investigate the long-term outcomes of the Mayo conservative hip system, a short metaphyseal stabilised stem, in patients with ONFH aged ≦30 years.

MATERIALS AND METHODS

We retrospectively reviewed 104 joints in 76 patients with ONFH who underwent THA using the Mayo conservative hip system with a minimum follow-up of 8 years. The mean follow-up period was 12.5 (range, 8-19) years. Patients were categorised into two age groups (≦30 years, n = 21 and > 30 years, n = 83). Radiographic evaluation was used to assess stem sinking, stress shielding, and spot welds. The clinical evaluations were performed using the Japanese Orthopedic Association (JOA) hip score. Postoperative major complication and revision surgery rates were also assessed.

RESULTS

The patient characteristics were similar between the two groups, except for the age. Revision surgeries were performed in five cases, with similar implant survival rates between the groups. Dislocations occurred in the older age group alone (four joints). One case of intra-operative periprosthetic femoral fracture was found in the younger age group. Stem sinking of > 3 mm occurred in one and seven joints in the younger and older age groups, respectively. Spot welds were observed in most joints (93.2%) in modified Gruen zones 2 and 6 without significant differences between the groups. Stress shielding showed no significant differences in the frequency of occurrence or location between the two groups. Furthermore,the JOA score showed no significant difference between the two groups.

CONCLUSION

The use of short stems in patients aged ≤ 30 years with ONFH showed favourable long-term outcomes.

Ovarian Suppression: Early Menopause and Late Effects

OPINION STATEMENT

Around 90% of breast tumours are diagnosed in the early stage, with approximately 70% being hormone receptor-positive. The cornerstone of adjuvant therapy for early-stage hormone receptor-positive breast cancer is endocrine therapy, tailored according to disease stage, biological characteristics of the tumour, patient's comorbidities, preferences and age. In premenopausal patients with hormone receptor-positive breast cancer, ovarian function suppression is a key component of the adjuvant endocrine treatment in combination with an aromatase inhibitor or tamoxifen. Moreover, it can be used during chemotherapy as a standard strategy for ovarian function preservation in all breast cancer subtypes. In the metastatic setting, ovarian function suppression should be used in all premenopausal patients with hormone receptor-positive breast cancer to achieve a post-menopausal status. Despite its efficacy, ovarian function suppression may lead to several side effects that can have a major negative impact on patients' quality of life if not properly managed (e.g. hot flashes, depression, cognitive impairment, osteoporosis, sexual dysfunction, weight gain). A deep knowledge of the side effects of ovarian function suppression is necessary for clinicians. A correct counselling in this regard and proactive management should be considered a fundamental part of survivorship care to improve treatment adherence and patients' quality of life.

Total knee arthroplasty survivorship and outcomes in young patients: a review of the literature and 40-year update to a longitudinal study

INTRODUCTION

Growing numbers of younger patients are electing to undergo total knee arthroplasty (TKA) for end-stage osteoarthritis. The purpose of this study was to compare established literature regarding TKA outcomes in patients under age 55, to data from an ongoing longitudinal young patient cohort curated by our study group. Further, we aimed to provide a novel update on survivorship at 40 years post-TKA from our longitudinal cohort.

METHODS

A literature search was conducted using the electronic databases PubMed, Embase, and Cochrane Library, using terms related to TKA, patients under age 55, and osteoarthritis. Demographic and outcome data were extracted from all studies that met the inclusion criteria. Data were divided into the "longitudinal study (LS) group," and the "literature review (LR) group" based on the patient population of the study from which it came.

RESULTS

After screening, 10 studies met the inclusion criteria; 6 studies comprised the LR group, and 4 studies comprised the LS group. 2613 TKAs were performed among the LR group, and 114 TKAs were longitudinally followed in the LS group. The mean patient ages of the LR and LS groups were 46.1 and 51, respectively. Mean follow-up was 10.1 years for the LR group. Mean postoperative range of motion was 113.6° and 114.5° for the LR and LS groups, respectively. All-cause survivorship reported at 10 years or less ranged from 90.6% to 99.0%. The LS cohort studies reported survivorship ranges of 70.1-70.6% and 52.1-65.3% at 30 and 40 years, respectively.

CONCLUSIONS

Young TKA patients demonstrated improved functionality at each follow-up time point assessed. Survivorship decreased with increasing lengths of follow-up, ultimately ranging from 52.1-65.3% at 40 years post-TKA. The paucity of literature on long-term TKA outcomes in this patient population reinforces the necessity of further research on this topic.

Comparison of Clinical and Genetic Characteristics Between Younger and Older Lung Cancer Patients

INTRODUCTION

The aim of this study was to analyze the clinical and genetic characteristics of young lung cancer cases, and to compare them with those of older cases.

METHODS

We used the Thoracic Tumors Registry (TTR) as a data source representative of lung cancer cases diagnosed in Spain, and included all cases registered until 9/01/2023 which had information on age at diagnosis or the data needed to calculate it. We performed a descriptive statistical analysis and fitted logistic regressions to analyze how different characteristics influenced being a younger lung cancer patient.

RESULTS

A total of 26,336 subjects were included. Lung cancer cases <50 years old had a higher probability of being women (OR: 1.38; 95% CI: 1.21-1.57), being in stage III or IV (OR: 1.32; 95% CI: 1.08-1.62), not having comorbidities (OR: 5.21; 95% CI: 4.59-5.91), presenting with symptoms at diagnosis (OR: 1.53; 95% CI: 1.29-1.81), and having ALK translocation (OR: 7.61; 95% CI: 1.25-46.32) and HER2 mutation (OR: 5.71; 95% CI: 1.34-24.33), compared with subjects ≥50 years. Among subjects <35 years old (n=61), our study observed a higher proportion of women (59.0% vs. 26.6%; p<0.001), never smokers (45.8% vs. 10.3%; p<0.001), no comorbidities (21.3% vs. 74.0%; p<0.001); ALK translocation (33.3% vs. 4.4%; p<0.001) and ROS1 mutation (14.3% vs. 2.3%; p=0.01), compared with subjects ≥35 years.

CONCLUSIONS

Lung cancer displays differences by age at diagnosis which may have important implications for its clinical management.

Surgical Outcomes of Rhegmatogenous Retinal Detachment and Fellow Eye Involvement in Adolescent and Young Adult Patients

PURPOSE

To investigate the associations, fellow eye retinal tear or detachment, and surgical outcomes of rhegmatogenous retinal detachments (RRDs) in young adults.

DESIGN

Retrospective consecutive case series.

SUBJECTS

Patients aged ≤ 30 years who underwent surgical repair for RRD between 2014 and 2021 at a single practice. The mean age was 23.85 years (range, 12-30 years).

METHODS

Data collected included demographics, preoperative clinical features of the RRD, visual acuity (VA), type of surgery performed, anatomic outcomes, OCT findings, fellow eye retinal tear or detachment, and postoperative complications.

MAIN OUTCOME MEASURES

Postoperative VA and single-surgery anatomic success rate.

RESULTS

One hundred one patients (109 eyes) were included. Sixty-seven patients (74 eyes) and 17 patients (19 eyes) were followed for ≥ 1 year and 5 years, respectively. The most common associations were myopia (66 eyes, 60.6%), trauma (8 eyes, 7.3%), and prior ocular surgery (7 eyes, 6.4%). Median preoperative Snellen VA was 20/70. The macula was attached in 31 eyes. Scleral buckle (SB) alone was performed in 75 eyes, pars plana vitrectomy (PPV) + SB was performed in 27 eyes, PPV alone was performed in 6 eyes, and cryotherapy with pneumatic retinopexy was performed in 1 patient. Single-surgery anatomical success was 88.7% for SB, 89.7% for PPV + SB, and 75% for PPV. The median final postoperative Snellen VA was 20/50. Twelve patients presented with bilateral RRDs, and sequential surgery was performed in 8 patients, followed by 4 patients who underwent surgery with fellow eye laser barricade. Fourteen patients (13.9%) developed a retinal tear or detachment in the fellow eye, with a mean interval of 8 months from presentation. Of the 17 patients who were followed for ≥ 5 years, 3 patients (17.6%) developed a fellow eye retinal tear or detachment. After initial anatomical success, 6 eyes (5.5%) developed proliferative vitreoretinopathy.

CONCLUSIONS

The most common association of RRD in this study was myopia. Scleral buckle alone was the most common surgical intervention. However, outcomes were generally favorable with SB-only and PPV + SB. Surgeons and patients should be aware of the risk of bilateral retinal detachment and the risk of fellow eye retinal tear and detachment. These patients require long-term surveillance in both eyes.

Characteristics of Very Young Patients Undergoing Total Hip Arthroplasty: A Contemporary Assessment

Background

This study aims to compare indications, patient characteristics, hospital factors, and complication rates between total hip arthroplasty (THA) patients aged 30 years or younger and those older than 30 years using a large national database.

Methods

The Premier Healthcare Database was utilized to identify primary THA patients from 2015 to 2021 who were aged ≤30 or >30 years. Patient demographics, hospital factors, and primary indications were compared for each cohort. Rates of complications and readmissions were assessed for each cohort by primary indication. Differences were assessed through univariate analysis.

Results

Overall, 539,173 primary THA patients were identified (age ≤30: 1849; >30: 537,234). Compared to the >30 cohort, the ≤30 cohort was more likely to be male (56.5% vs 44.9%, P < .001) and non-White (34.0% vs 14.2%, P < .001). The most common indications for THA in the ≤30 cohort were osteonecrosis (49.3%), osteoarthritis (17.8%), and congenital hip deformities (16.0%), and in the >30 cohort, they were osteoarthritis (77.0%), other arthritis (11.3%), and osteonecrosis (5.4%). Patients aged ≤30 years had lower rates of respiratory failure (0.16% vs 0.57%, P < .001), acute renal failure (0.32% vs 1.72%, P < .001), and urinary tract infection (0.38% vs 1.11%, P = .003) than those aged >30 years, but higher rates of wound dehiscence (0.59% vs 0.29%, P = .015) and transfusion (3.68% vs 2.21%, P < .001). There were no differences in 90-day readmission rates (P = .811) or 90-day in-hospital death (P = .173) between cohorts.

Conclusions

Younger patients undergoing THA differed significantly in indication, patient characteristics, and hospital factors compared to the older population on univariate analysis. Despite differences in indications, the cohorts did not differ markedly with regard to complication rates in this study.

Efficacy and safety of chemotherapy in young patients with advanced gastroesophageal adenocarcinoma: data from the Spanish AGAMENON-SEOM registry

BACKGROUND

Gastroesophageal adenocarcinoma in young adults (GCYA) counts for 10-15% of diagnoses. Previous studies have mainly focused on surgical outcomes in patients with resectable tumors; however, systemic therapy for advanced GCYA remains under-evaluated. This study aims to assess the efficacy-related outcomes and safety of first-line chemotherapy (CT) in younger versus older patients with advanced gastroesophageal adenocarcinoma.

METHODS

Patients with advanced gastroesophageal adenocarcinoma from the AGAMENON-SEOM registry treated with first-line polychemotherapy between January 2008 and October 2022 were included. We compared clinicopathological features, therapies received, efficacy-related outcomes, and toxicity between individuals aged < and ≥ 45 years.

RESULTS

Out of 3386 patients, 263 (7.8%) were < 45 years. Young patients exhibited a higher proportion of females affected, lower ECOG-PS ≥ 2, fewer comorbidities, and more aggressive disease-related features, such as higher proportion of diffuse subtype, signet-ring cells, plastic linitis, grade 3, peritoneal metastases and metastatic disease at diagnosis. They received more triple-agent combinations and underwent more surgeries in metastatic setting. No significant differences were observed between groups in overall response rate (53.1% vs. 52.3% in < and ≥ 45 years, respectively, p = 0.579), progression-free survival (6.1 vs. 6.83 months, p = 0.158) and overall survival (11.07 vs. 10.81 months, p = 0.82), even after adjusting for potential confounding factors. Grade 3-4 adverse events were comparable in both groups, although toxicity leading to treatment discontinuation was more frequent in older patients.

CONCLUSIONS

In the AGAMENON-SEOM registry, younger patients with GCYA exhibited more aggressive clinicopathological features, and despite receiving more aggressive treatments, similar efficacy outcomes and toxicity profiles were achieved compared to their older counterparts. In the AGAMENON-SEOM registry, GEAC in < 45 years showed more aggressive clinicopathological features and, although treated with more intense first-line CT regimens, similar efficacy outcomes and toxicity were achieved compared to older patients.

Lung Cancer in Young Patients is Associated With More Advanced Disease but Better Overall Survival

INTRODUCTION

It is unclear whether nonsmall cell lung cancer (NSCLC) is associated with more aggressive disease and worse overall survival (OS) among younger patients. The aim of this study is to evaluate outcomes in young patients. We hypothesize that young age is associated with more advanced disease upon presentation, but better OS.

METHODS

We identified patients with NSCLC from 2004 to 2018 in the National Cancer Database. Patients were categorized in 3 groups: age≤50, 51-84, and ≥85 y. The outcomes were OS, stage IV NSCLC and clinical nodal metastasis. OS was analyzed using multivariate cox and Kaplan-Meier analysis accounting for stage, comorbidities, and other factors. The association of age, presentation with stage IV NSCLC and node positivity was analyzed using multivariate logistic regression.

RESULTS

In total 1,651,744 patients were identified: 92,506 (5.57%) age ≤50, 1,477,723 (88.90%) age 51-84, and 91,964 (5.53%) age ≥85. Multivariate model showed stage IV NSCLC was associated with age ≤50 (OR 1.17 (1.15-1.20) P < 0.001) and ≥85 (odds ratio (OR) 1.03 (1.02-1.04) P < 0.001). Clinical lymph node positivity was associated with age ≤50 (OR 1.27 (1.23-1.30) P < 0.001). Relative to patients 51-84, the ≤50 group was associated with better survival in Stage I (hazard ratio (HR) 0.61 versus 1.00), stage II (HR 1.12 versus 1.50), stage III (HR 2.12 versus 2.53), and stage IV (HR 6.65 versus 7.53).

CONCLUSIONS

Patients ≤50-y-old present with more advanced NSCLC, but better OS compared to patients 51-84. These findings suggest the need for increased awareness regarding NSCLC among age groups seen as low risk.

Early and long-term outcomes of young adult patients ≤30 years old with acute type A aortic dissection

OBJECTIVES

The aim of this study was to investigate the early and long-term outcomes after total arch replacement (TAR) and frozen elephant trunk (FET) implantation in adult patients ≤30 years with acute type A aortic dissection (ATAAD).

METHODS

All young adult patients (≤30 years) with ATAAD who underwent TAR and FET between 2009 and 2017 were enrolled. The end points were major organ morbidity and mortality, aortic-related events and reoperation.

RESULTS

The mean age of all 83 patients was 25.9 (standard deviation, 3.3) years. The in-hospital mortality was 9.64% (8/83), and 9 (10.8%) patients required re-exploration for bleeding. The aortic-related events risk was 42.7% (32/75) and the aortic reoperation risk was 17.3% (13/75). Overall survival was 85.5% [95% confidence interval (CI), 75.9-91.5%] at 5 years and 75.9% (95% CI, 63.3-84.7%) at 10 years. The cumulative incidence of aortic-related events was 35% (95% CI, 24-47%) at 5 years and 58% (95% CI, 36-75%) at 10 years; the cumulative reoperation rate was 15% (95% CI, 7.9-24%) at 5 years and 17% (95% CI, 9.2-27%) at 10 years. Marfan syndrome significantly increased the aortic-related events (P = 0.036) and reoperation (P = 0.041) risks.

CONCLUSIONS

Despite extensive repair in young ATAAD patients, the late aortic dilatation and reoperation risk remain high. The TAR and FET procedures achieved satisfactory early outcomes and reduced late aortic dilatation and reoperation in young patients compared with other records. Close follow-up and aggressive early reintervention are essential for patients with aortic-related risk factors early in life.

Epicardial adipose tissue, pulmonary veins anatomy, and the P-wave/PR interval ratio in young patients with atrial fibrillation

Background

Atrial fibrillation (AF) is uncommon in the youngest population. Epicardial adipose tissue (EAT) volume has been proposed as an independent AF risk factor.

Objective

The aim of this retrospective study was to evaluate the impact of the EAT, the anatomy of the pulmonary veins (PVs), and electrocardiogram (ECG) features in these young patients with AF.

Methods

Sixty-two patients divided in 2 groups, one with history of paroxysmal AF treated with ablation and the other, a control group, all younger than 30 years of age, were included. Computed tomography scans were performed in both groups to estimate the PVs anatomy and EAT volume. Twelve-lead ECGs were performed in all patients. Patients underwent follow-up in our outpatient clinic (35.9 ± 18.3 months).

Results

In the AF group, the EAT volume around the left atrium was 22.25 ± 9.3 cm3 compared with 12.61 ± 3.37 cm3, showing a statistically significance difference (P = .003). Family history resulted to be another significant risk factor (P = .009). During follow-up, 67.7% of the patients treated were still free of events. The anatomy and morphology of the right-sided PVs seemed to play a more consistent role in the patients with AF recurrences (P = .04). The P/PR ratio, a new ECG index, seemed predict AF recurrences after ablation (P = .03).

Conclusion

The abundance of EAT seems related to the risk of developing AF in young patients. The recurrence of AF is about 33% and does not seem related to the EAT volume, but rather to the anatomy of the PVs. A higher P/PR ratio might suggest recurrences.

Intertrochanteric curved varus osteotomy for subchondral fracture of the femoral head: a case series

Although favorable results have been reported with total hip arthroplasty, joint-preserving treatment should be the first choice for subchondral fracture of the femoral head (SFF) in young patients. This study reviewed four young male patients with SFF who underwent intertrochanteric curved varus osteotomy (CVO). The patients had a mean age of 32.3 years (range: 18-49 years). Conservative treatment was initially attempted in all cases, but failed to alleviate the pain, leading to surgical intervention at an average time of 6 months (range: 4-10 months) after symptom onset. As the fracture sites were located medial to the lateral edge of the acetabulum in all cases, CVO was performed to achieve a postoperative intact ratio of ≥ 34% in the weight-bearing region of the femoral head. The average follow-up period after surgery lasted 4.3 years (range: 2-7 years). Clinical and radiographic assessments were performed pre- and postoperatively. At the latest follow-up, the mean Harris hip score improved from 67.3 preoperatively to 99.5 postoperatively. The average preoperative intact ratio of the weight-bearing region of the femoral head was 12.3%, which increased to 44.3% postoperatively. No progression to femoral head collapse or joint space narrowing was observed on the plain radiographs. CVO is a simple, less-invasive, and beneficial approach for treating SFF in young patients whose fractures occur medial to the lateral edge of the acetabulum.

Ex vivo adult stem cell characterization from multiple muscles in ambulatory children with cerebral palsy during early development of contractures

Cerebral palsy (CP) is one of the most common conditions leading to lifelong childhood physical disability. Literature reported previously altered muscle properties such as lower number of satellite cells (SCs), with altered fusion capacity. However, these observations highly vary among studies, possibly due to heterogeneity in patient population, lack of appropriate control data, methodology and different assessed muscle. In this study we aimed to strengthen previous observations and to understand the heterogeneity of CP muscle pathology. Myogenic differentiation of SCs from the Medial Gastrocnemius (MG) muscle of patients with CP (n = 16, 3-9 years old) showed higher fusion capacity compared to age-matched typically developing children (TD, n = 13). Furthermore, we uniquely assessed cells of two different lower limb muscles and showed a decreased myogenic potency in cells from the Semitendinosus (ST) compared to the MG (TD: n = 3, CP: n = 6). Longitudinal assessments, one year after the first botulinum toxin treatment, showed slightly reduced SC representations and lower fusion capacity (n = 4). Finally, we proved the robustness of our data, by assessing in parallel the myogenic capacity of two samples from the same TD muscle. In conclusion, these data confirmed previous findings of increased SC fusion capacity from MG muscle of young patients with CP compared to age-matched TD. Further elaboration is reported on potential factors contributing to heterogeneity, such as assessed muscle, CP progression and reliability of primary outcome parameters.

Surgery for young onset diverticulitis: is it curative?

PURPOSE

Previously considered a disease of old age, diverticular disease is increasingly prevalent in younger populations. Guidelines on surgical resection have shifted from recommending resection for all young onset patients to an individualized approach. Therefore, we aim to determine demographics and outcomes including radiographic and surgical recurrence rates in patients < 40 years old undergoing resection for diverticular disease.

METHODS

A retrospective, single center study was performed. All patients ≤ 39 years undergoing operative intervention for left-sided diverticular disease between Jan 2010 and July 2017 were included. Recurrence was determined by individual review of imaging and operative reports.

RESULTS

Overall, 147 (n = 107/72.8% male, mean age = 34.93 ± 4.12 years) patients were included. The majority were ASA 1 or 2 (n = 41/27.9% and n = 82/55.8%). The most common surgical indication was uncomplicated diverticulitis (n = 77, 52.4%) followed by perforation (n = 26/17.7%). The majority (n = 108/73.5%) of cases were elective. Seventy-nine (57.3%) of all cases were performed laparoscopically. Primary anastomosis without diversion was the most common surgical outcome (n = 108/73.5%). Median length of stay was 5 (4, 7) days. There was no mortality. There were three (2.0%) intraoperative and 38 (25.9%) postoperative complications. The most common complication was anastomotic leak (n = 6/4.1%). The majority (n = 5) of leaks occurred after elective surgery. Two neoplastic lesions (1.3% of cohort) were found (1 adenoma with low-grade dysplasia/1 polyp cancer). Over a mean follow-up of 96 (74, 123) months, only 2 (1.3%) patients experienced a surgical or radiological recurrence.

CONCLUSION

Both neoplasia and recurrence after resection for diverticular disease in young onset patients are rare. Leaks after primary anastomosis even in the elective setting warrant careful consideration of a defunctioning ileostomy.

Bendamustine-Rituximab in Young CLL: Relevance in the Era of Small Molecule Inhibitors

Purpose

Chemo-immunotherapies like Fludarabine-Cyclophosphamide-Rituximab (FCR) are used for treatment of chronic lymphocytic leukemia (CLL) in young and fit patients while Bendamustine-Rituximab (BR) is used in older patients. In a resource constrained setting, managing toxicities of FCR chemotherapy is challenging and this study explores the use of upfront BR treatment in young CLL patients (age < 65).

Methods

Data of 61 CLL patients treated with the BR regimen between 2016 and 2020 was analysed. Overall-survival and progression-free-survival (OS and PFS) were compared between the two age groups (< / > 65 years) and correlated with the fluorescent-in-situ-hybridization (FISH) data, duration of illness and time to initiation of chemotherapy.

Results

Out of 61 patients, 34 (85%) were below 65 years. Five patients had del 17p and were excluded from the analysis. Forty patients had indications for treatment. Twenty-four (70.5%) of the forty patients achieved overall response; 10 developed progressive disease. The median OS and PFS was 1874 days (95% CI 1617-2130 days) and 1226 days (95% CI 1021-1432 days) respectively and were non inferior between the 2 age-groups. There were no correlations with clinical, laboratory or FISH parameters. The OS and PFS were better for patients with longer time to initiation of chemotherapy as compared to those with short duration of illness and short wait-and-watch periods (p < 0.000).

Conclusions

Our results show that BR chemotherapy can safely and effectively be used in upfront treatment of young CLL patients and provide durable responses.

[Correlation between spinous process deviation and lumbar disc herniation in young patients]

OBJECTIVE

To explore the relationship between spinous process deviation and lumbar disc herniation in young patients.

METHODS

From March 2015 to January 2022, 30 treated young (under the age of 30) patients with lumbar disc herniation were included as the young group. In addition 30 middle-aged patients (quinquagenarian group) with lumbar disc herniation and 30 patients with non-degenerative spinal diseases (young non-degenerative group) were selected as control groups. The angle of the spinous process deviation was measured on CT and statistically analyzed by various groups. All the data were measured twice and the average value was taken and recorded.

RESULTS

The average angle of spinous process deviation in the degenerative lumbar vertebra of young patients were (3.89±3.77) degrees, similar to the (3.72±2.98) degrees of quinquagenarian patients(P=0.851). The average angle of s spinous process deviation young non-degenerative group were (2.20±2.28) degrees, significantly less than young group(P=0.040). The spinous process deviation angle of the superior vertebral of the degenerative lumbar in the young group was (4.10±3.44) degrees, which similar to the (3.47±2.87) degrees in the quinquagenarian group (P=0.447). A total of 19 young patients had the opposite deviation direction of the spinous process of the degenerative lumbar vertebra and upper vertebra, while only 7 quinquagenarian patients had this condition(P=0.02). The type of lumbar disc herniation in young patients had no significant relationship with the direction of spinous process deflection of the degenerative or upper lumbar vertebra (P>0.05).

CONCLUSION

Spinous process deviation is a risk factor of young lumbar disc herniation patients. If the deviation directions of adjacent lumbar spinous processes are opposite, it will increase the incidence of lumbar disc herniation in young patients. There was no significant correlation between the type of disc herniation and the deviation direction of the spinous process of the degenerative or upper lumbar vertebra. People with such anatomical variation can strengthen the stability of spine and prevent lumbar disc herniation through reasonable exercise.

Total hip arthroplasty for failed internal fixation of femoral neck fracture: a retrospective study with 2-14 years' follow-up of 345 patients

OBJECTIVES

The purpose of this study was to analyze mid- to long-term outcomes of total hip arthroplasty (THA) following failed internal fixation of femoral neck fracture.

METHODS

This study retrospectively analyzed 345 patients with femoral neck fracture who underwent THA after failure of internal fixation at our hospital between January, 2003 and December, 2019. Patients older than 55 years (n = 175) and patients no older than 55 years (n = 170) were compared in terms of complications and survival rates during follow-up, which lasted a mean of 6 years.

RESULTS

The two age groups showed similarly low incidence of complications and similarly long periods of survival without revision surgery. Only three younger patients and two older patients underwent revision surgery during follow-up. The two groups showed similarly high survival rates at the end of follow-up (> 93%). Younger patients showed significantly bettter Harris hip score at last follow-up (90.2 vs. 88.1 points, p < 0.001) without clinically significant difference, but they required THA significantly earlier after internal fixation (4.4 vs. 6.8 years, p < 0.001).

CONCLUSIONS

THA after failed internal fixation of femoral neck fracture is a well tolerated and effective procedure in older and younger patients.

Analyses of associated factors with concomitant meniscal injury and irreparable meniscal tear at primary anterior cruciate ligament reconstruction in young patients

Purpose

Although several factors related to the concomitant meniscal injury at anterior cruciate ligament reconstruction (ACL-R) have been investigated in a general population, few studies have identified the risk factors of meniscal tear severity in young patients in which the majority of ACL tears occur. The purpose of this study was to analyze the associated factors with meniscal injury and irreparable meniscal tear and the timeline for medial meniscal injury at ACL-R in young patients.

Methods

A retrospective analysis of young patients (13 to 29 years of age) who underwent ACL-R by a single surgeon from 2005 to 2017 was conducted. Predictor variables (age, sex,body mass index [BMI], time from injury to surgery [TS], and pre-injury Tegner activity level) for meniscal injury and irreparable meniscal tear were analyzed with multivariate logistic.

Results

Four hundred and seventy-three consecutive patients with an average of 31.2 months post-operative follow-up were enrolled in this study. The risk factors for medial meniscus injury were TS (<= 3 months) (odds ratio [OR], 3.915; 95% CI, 2.630-5.827; P < .0001) and higher BMI (OR, 1.062; 95% CI, 1.002-1.125; P = 0.0439). The presence of irreparable medial meniscal tears correlated with higher BMI (OR, 1.104; 95% CI, 1.011-1.205; P = 0.0281).

Conclusion

An increased time from ACL tear to surgery of 3 months was strongly associated with an increased risk of medial meniscus injury, but not related to irreparable medial meniscal tear at primary ACL reconstruction in young patients.

Accessory renal arteries - a source of hypertension: A case report

BACKGROUND

Secondary hypertension is a relatively rare condition most commonly caused by renovascular disease due to atherosclerotic vascular disease or fibromuscular dysplasia. Although accessory renal arteries are frequent, to date, only six cases of secondary hypertension determined by their existence have been reported.

CASE SUMMARY

We describe a case of a 39-year-old female who came to the emergency department with an urgent hypertensive crisis and hypertensive encephalopathy. Despite normal renal arteries, the computed tomography angiography revealed an inferior polar artery with 50% stenosis of its diameter. Conservative treatment with amlodipine, indapamide and perindopril was adopted, leading to blood pressure control within one month.

CONCLUSION

To the best of our knowledge, there are controversies regarding accessory renal arteries as a potential etiology for secondary hypertension, but the seven similar cases already described, along with the current case, could reinforce the necessity of more studies concerning this subject.

Clinical outcomes after reverse shoulder arthroplasty in patients 60 years old and younger; medium-term results

Background

Reverse total shoulder arthroplasty (RTSA) has been well-described as a surgical solution to manage rotator cuff tear arthropathy in elderly, low demand paitents. As experience has increased along with improvements in technique and implant design, RTSA has become increasingly used to manage more varied pathologic conditions of the shoulder in younger, more active patients. This study evaluates outcomes in a consecutive series of patients aged 60 years old and younger after undergoing RTSA.

Methods

There were 94 shoulders in 89 patients enrolled. Mean age of the cohort was 54.8 (range 18-60 years). Surgical indications included rotator cuff tear arthropathy, irreparable rotator cuff tear without arthritis, glenohumeral arthritis with erosive glenoid deformity, inflammatory arthropathy, proximal humerus fracture nonunion/malunion and failed prior shoulder arthroplasty. Sixty-one shoulders (70%) had undergone at least one prior surgery. Of these, 6 shoulders (6% of total cohort) had a prior failed arthroplasty. Clinical outcomes (American Shoulder and Elbow Surgeons score, Western Ontario Osteoarthritis of the Shoulder index; visual analog scale pain), radiographic outcomes and complications were analyzed and assessed for correlation with patient demographic factors.

Results

The mean follow-up for this cohort was 4.9 years (range 2-12 years). Subjects experienced improvements in ASES score and pain (P < .001) and active forward elevation (88° preop to 135° postop, P < .001). Prior operation correlated with worse postoperative ASES and WOOS scores. Higher demand occupation correlated with less improvement in pain scores. The overall complication rate was 12%. Seven shoulders (7%) underwent an additional procedure. There was a 2% incidence of dislocation and a 4% incidence of acromial stress fracture. There was a 36% incidence of notching.

Conclusion

With medium-term follow-up, RTSA is a reliable and predictable operation to manage various pathologic conditions in patients aged 60 years or less. Patients predictably experience significant improvements in pain and range of motion while assuming a modest complication risk. Long-term study is needed to understand potential for late complications or implant failure.

Unicompartmental knee arthroplasty in patients under the age of 60 years provides excellent clinical outcomes and 10-year implant survival: a systematic review : A study performed by the Early Osteoarthritis group of ESSKA-European Knee Associates section

PURPOSE

The purpose of the present study was to systematically review the clinical and functional outcomes following medial unicompartmental knee arthroplasty (UKA) in patients under the age of 60 years old.

METHODS

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, studies between 2012 and April 2022, on patients 18-60 years old who have had a unicompartmental knee replacement evaluating patient-reported outcomes measures (PROMs), were included. The Knee Society Scores (KSS) clinical score was considered the primary outcome. Pre- and post-operative range of motion (ROM), PROMs, complications and survival were recorded. Paired sample t testing was performed to compare the pre-operative with post-operative KSS.

RESULTS

Seventeen articles comprising 2083 unicompartmental arthroplasties were included. The follow-up range was between 1 and 15 years. In eligible studies, all reported outcomes were improved following UKA. The mean KSS clinical was significantly improved from 45.5 (SD: 9.6) pre-operatively to 89.4 (SD: 4.4) post-operatively (p = 0.0001). Mean implant survival ranged 86-96.5% at 10 years follow-up. There was no significant difference between mobile and fixed bearing in terms of ROM and KSS clinical. In total, 92 revisions and 7 re-operations with implant retention were reported.

CONCLUSION

Unicompartmental knee arthroplasty for medial osteoarthritis is a safe, reliable and effective treatment option for patients of 60 years or younger. It provides pain relief, satisfactory activity level, excellent clinical outcomes, and up to 96.5% implant survival at 10-year follow-up.

Postoperative delayed neurocognitive recovery: Evaluation of its incidence and correlation with intraoperative cerebral desaturation - A prospective observational study

BACKGROUND

Delayed neurocognitive recovery (DNR) is commonly seen in patients in the postoperative period. Literature has shown that monitoring cerebral desaturation intraoperatively can predict the development of DNR in elderly patients undergoing surgery in prone position. This prospective observational study was conducted in patients of all ages, with the primary objective to determine the incidence of DNR and its correlation with cerebral oximetry. The secondary objectives were to determine if intraoperative cerebral desaturation influenced the neuropsychometric variables from preoperative to postoperative period.

METHODS

This study included 61 patients, aged > 18 years undergoing spinal surgery in prone position. An evening before surgery and at 48 h postoperatively, patients were subjected to neuropsychological examination; Hindi Mental State Examination, Colour Trail Test 1 (CTT 1), CTT 2, Auditory Verbal Learning (AVLT) tests conducted by principal investigator (PI). DNR was defined as a 20% change in any of the test scores from the baseline. rSO₂ was recorded bilaterally every 10 min throughout surgery by an independent person. Cerebral desaturation was defined as a 20% drop in rSO₂ from the control value.

RESULTS

The incidence of DNR was 24.6%. The duration of anesthesia and cerebral desaturation were found to be independently predictive of DNR, with each hour of anesthesia causing a two-fold increase in the chances of development DNR (P = 0.019) and presence of cerebral desaturation causing a 6-fold increase (P = 0.039). CTT 1 and CTT 2 tests had significantly larger increase in test scores in the postoperative period, in patients with cerebral desaturation.

CONCLUSION

Duration of anesthesia and cerebral desaturation were factors predictive of the development of DNR in patients undergoing spine surgery in prone position.

Tumor characteristics, therapy, and prognosis in young breast cancer patients ≤ 35 years

PURPOSES

Young breast cancer patients aged 35 years and younger are a small group of women who tend to present at high-risk form of the disease. More analysis of the data on tumor characteristics, treatment, and survival is necessary to help improving treatment and outcome.

METHODS

In this retrospective study, we compared the clinical and tumor characteristics, the treatments, and the survival of 257 women aged ≤ 35 years, with 6566 women aged 50-69 years. We used a registry-based data of patients with invasive, non-metastatic breast cancer diagnosed between 2000 and 2015.

RESULTS

Young women showed lower rate of hormone receptor (HR) positivity. Their tumors were more often HER2-positive, which showed lower rate of differentiation and higher rate of Ki-67 expression compared to their older counterparts. Women aged 35 years and younger were more likely to undergo neoadjuvant therapy and mastectomy. Endocrine therapy was underrepresented in young patients. 5-Year disease-free survival (DFS) was significantly lower in the younger patient group (81.7% vs. 91.3%, p < 0.001), while 5-year overall survival (OS) was not impaired (91.4% vs. 91.1%, p = 0.847).

CONCLUSION

The unfavorable disease-free survival in the group of younger patients might be explained by their unfavorable tumor characteristics. The surgical treatment appears to be more aggressive in young breast cancer patients and is more frequently combined with chemotherapy and immunotherapy, either in a neoadjuvant or in an adjuvant setting.

Dual Mobility Total Hip Replacements in Young Patients- A Systematic Review

Background

There is little consensus on outcomes of dual Mobility total hip replacement (DM-THR) in younger patients. We performed a systematic review to examine this.

Methods

A systematic review of all observational studies and randomised controlled trials of patients under 70 with primary DM-THR in MEDLINE, EMBASE, Pubmed, Cochrane was performed according to PRISMA guidelines. Collected data included demographics, revision, dislocation and infection rates and functional scores.

Results

Twelve papers studying 738 DM-THR in 664 patients were included. The mean patient age was 46.9 years (13.5-69.0), with 319 (48.0%) being female and 419 (52.0%) being male. After an average follow-up of 90.0 months (1-371 months), the revision rate was 12.7% (84 hips), 0 dislocations were reported but 2.5% (15 hips) underwent intra-prosthetic dislocation. 32.1% hip revisions were due to aseptic loosening.

Conclusion

Limited literature surrounding the use of DM-THR suggests favourable stability but higher revision rates than conventional THR.

Peri-procedural and mid-term follow-up age-related differences in leadless pacemaker implantation: Insights from a multicenter European registry

BACKGROUND

Age-related differences on leadless pacemaker (LP) are poorly described. Aim of this study was to compare clinical indications, periprocedural and mid-term device-associated outcomes in a large real-world cohort of LP patients, stratified by age at implantation.

METHODS

Two cohorts of younger and older patients (≤50 and > 50 years old) were retrieved from the iLEAPER registry. The primary outcome was to compare the underlying indication why a LP was preferred over a transvenous PM across the two cohorts. Rates of peri-procedural and mid-term follow-up major complications as well as LP electrical performance were deemed secondary outcomes.

RESULTS

1154 patients were enrolled, with younger patients representing 6.2% of the entire cohort. Infective and vascular concerns were the most frequent characteristics that led to a LP implantation in the older cohort (45.8% vs 67.7%, p < 0.001; 4.2% vs 16.4%, p = 0.006), while patient preference was the leading cause to choose a LP in the younger (47.2% vs 5.6%, p < 0.001). Median overall procedural (52 [40-70] vs 50 [40-65] mins) and fluoroscopy time were similar in both groups. 4.3% of patients experienced periprocedural complications, without differences among groups. Threshold values were higher in the younger, both at discharge and at last follow-up (0.63 [0.5-0.9] vs 0.5 [0.38-0-7] V, p = 0.004).

CONCLUSION

When considering LP indications, patient preference was more common in younger, while infective and vascular concerns were more frequent in the older cohort. Rates of device-related complications did not differ significantly. Younger patients tended to have a slightly higher pacing threshold at mid-term follow-up.

COVID-19 and renal involvement: a prospective cohort study assessing the impact of mild SARS-CoV-2 infection on the kidney function of young healthy males

PURPOSE

COVID-19 frequently affects the kidneys with symptoms ranging from mild proteinuria to progressive acute kidney injury. This prospective study aimed to assess the short- and long-term impact of asymptomatic and mild COVID-19 on the renal function of healthy young adults, and to determine the correlation between viral load and kidney function among these patients.

METHODS

This was a prospective cohort study conducted over a period of 6 months. Patients were followed-up at baseline, and then after 3 and 6 months, respectively. Real-time PCR cycle threshold (CT) was used to determine the viral load and disease activity. Patients were classified into two groups with either asymptomatic COVID-19 or mild pneumonia. The assessment parameters were variables that could directly or indirectly relate to the renal function.

RESULTS

A total of 48 patients were included and evaluated. The majority of patients (62.5%) had asymptomatic COVID-19 disease. Patients with mild pneumonia had significantly higher serum creatinine (SCr) at the time of COVID-19 diagnosis (beta = 12.836, 95% CI = 2.405-23.268, P = 0.019), after 3 months (beta = 14.345, 95% CI = 1.149-27.542, P = 0.035), and after 6 months (beta = 14.100, 95% CI = 0.730-27.470, P = 0.040) compared to asymptomatic patients. Mild pneumonia was also significantly associated with lower serum albumin level at the time of COVID-19 diagnosis (beta = - 6.317, 95% CI = - 9.448-- 3.185, P < 0.001).

CONCLUSION

Mild COVID-19 is associated with mild renal involvement without AKI. Changes in the renal function appear to be related to reduced creatinine clearance and possible albumin leakage in the acute phase of the disease. The reduction in creatinine clearance is not predicted by viral load, and it appears to be a long-term effect of the disease that can last for at least 6 months.

[Research Progress of Treatment for NSCLC in Young Patients]

Non-small cell lung cancer (NSCLC) young patients (≤45 years old), despite their low prevalence, have unique clinical and pathological features. Its morbidity has been on the rise in recent years. With the concept of individualized lung cancer treatment, related researches are gradually gaining attention. In addition, the treatment response and prognosis in NSCLC young patients are different from older patients, so the study of NSCLC young patients is of great clinical significance. This article reviews the clinical manifestations, treatment and prognosis of NSCLC young patients.

A Clinicopathological Correlation of Bladder Cancer in Young and Old Patients: Our Experience and Review of Literature

To compare the clinical, cystoscopic, and pathological characteristics of bladder cancer in patients younger than 40 years of age and those of patients older than 40 years of age. We conducted a prospective observational study at our department from September 2019 to February 2021 to compare the clinico-pathological characteristics of young and old patients with biopsy proven bladder cancer after a transurethral resection of bladder tumour. The patients were managed according to standard guidelines. Two hundred sixty-eight patients of bladder cancer were included in the analysis. Out of these, 58 patients were < 40 years of age and 210 were > 40 years. The mean age of two groups were 31.43 ± 6.30 vs 59.08 ± 9.87 years. With respect to tumour grade, 36.2% (versus 17.6%) of young patients had low grade tumour, and 58.6% had high-grade tumour (versus 82.4%). In the young population, 63.8% patients had NMIBC (versus 61.9%) and 36.2% had MIBC (versus 38.1%). Even in the NMIBC group, a large majority of young patients had high-risk disease (51.4%). The incidence of bladder cancer is on the rise in the northern belt of India, especially in the younger age group. High exposure to smoke and heavy metals in drinking water/occupation are the major risk factors. Majority of young patients aged < 40 years had a high-grade disease on presentation and a large subset had muscle invasive bladder cancer, contrary to previously reported studies.

Outcomes of open and endovascular infra-inguinal revascularization are poor in young patients with atherosclerotic peripheral artery disease but do not differ between genders

OBJECTIVES

The effect of gender on the outcomes of revascularization procedures in young patients with premature atherosclerotic peripheral arterial disease (PAD) is not known. The objective of this study was to compare short-term and long-term outcomes between young males and females undergoing infra-inguinal revascularization procedures.

METHODS

We examined postoperative outcomes of male and female PAD patients under the age of 55 who underwent infra-inguinal revascularization procedures at a single tertiary institution from 2011 to 2019. Primary outcomes included 30-day morbidity, patency of the revascularization procedures, and major adverse limb events (MALE). Secondary outcomes included survival, amputation rate, reintervention rate, improvement of ankle-brachial index (ABI), and number of reinterventions.

RESULTS

Eighty-one infra-inguinal revascularization procedures (46 endovascular and 35 open procedures) were reviewed including 45 procedures in 37 males and 36 procedures in 31 females. Fifty-three (65.4%) of the procedures were performed in patients with chronic limb-threatening ischemia symptoms. The rest were treated for life-disabling claudication. The female patients were younger, had higher body mass index, and were more likely to have diabetes, hyperlipidemia, or chronic obstructive pulmonary disease in comparison to males. Thirty-day major adverse cardiovascular event was 0.0% and MALE was 16.0%. Mean follow-up was 806.2 days. At 1 year, primary patency was 34.4 ± 6.2%, primary assisted patency was 52.7 ± 6.5%, secondary patency was 61.8 ± 6.3%, and MALE-free rate was 47.0 ± 6.4%. For secondary outcomes at 1 year, amputation-free rate was 92.5 ± 3.2%, reintervention-free rate was 50.2 ± 6.4%, and survival was 96.2 ± 2.6%. By the end of the study, overall mortality rate was 14.8% and major amputation rate was 13.6%. No major differences were observed between males and females among these outcomes. A smaller improvement in ABI after revascularization was noted in females compared to males (female 0.2 ± 0.2 vs male 0.4 ± 0.2, p = .04). Among patients who required reintervention, females required a higher number of reinterventions than males (female 1.7 ± 2.5 vs male 0.8 ± 1.1, p = .03).

CONCLUSIONS

There were no significant differences in short-term and long-term outcomes between males and females under the age of 55 after infra-inguinal revascularization. Poor patency, high MALE rate, and high mid-term mortality, and amputation rates after revascularization in young PAD patients highlight the need for improved strategies to treat premature PAD.

Patterns of care over 10 years in young breast cancer patients in the Netherlands, a nationwide population-based study

INTRODUCTION

Each year, around 600 young (<40 years) breast cancer (BC) patients are registered in the national NABON Breast Cancer Audit (NBCA). The aim of this study is to compare patient and treatment characteristics of young and older age BC patients over time with a focus on outcome of quality indicators (QIs). Furthermore, we analysed whether de-escalation trends of treatment can be recognized to the same degree in both patient groups.

MATERIAL AND METHODS

From October 2011 to October 2020 all patients treated for stage I-III invasive BC were included. Tumour characteristics, treatment variables and outcome of QIs of two age categories young (<40 years) and older patient (≥40 years) were analysed.

RESULTS

In total 114,700 patients were included: 4.6% young patients and 95.4% older patients. Young patients more often presented with a palpable mass, higher stage, and triple-negative BC. Overall, young patients more often started with neoadjuvant systemic treatment (NST) (54.3% vs. 18.6%) and a greater proportion of the young patients retained their breast contour after surgery (73.5% vs. 69.3%). De-escalation trends such as decrease in axillary lymph node dissections and in the use of boost were observed. The omission of radiation treatment after breast conserving surgery was only observed in older patients.

CONCLUSION

Although this study shows that young women more often present with unfavourable tumours, therapeutic procedures are performed with a higher adherence to the QIs than for older patients and young women do benefit from some de-escalation trends to the same extend as older patients.

Meniscal repair at the time of primary ACLR does not negatively influence short term knee stability, graft rupture rates, or patient-reported outcome measures: the STABILITY experience

PURPOSE

To assess how meniscal repair and excision impact short term patient-reported outcome measures (PROMs), knee stability, and early graft rupture rates following primary hamstring anterior cruciate ligament reconstruction (ACLR) with or without lateral extra-articular tenodesis (LET) in a group of young active patients where meniscal repair is commonly advocated.

METHODS

Six hundred and eighteen patients under 25 years of age at high-risk of graft failure following ACLR were recruited to the Stability 1 study. Multivariable regression models were developed to identify statistically and clinically significant surgical and demographic predictors of Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee Subjective Knee Form (IKDC), ACL Quality of Life Questionnaire (ACL-QOL) and Marx Activity Rating Scale (MARS) scores. Chi-Square tests of independence were used to explore the association between meniscal status (torn, not torn), meniscal treatment (excision or repair), graft rupture, and rotatory knee laxity.

RESULTS

Medial meniscus repair was associated with worse outcomes on the KOOS (β = -1.32, 95% CI: -1.57 to -1.10, p = 0.003), IKDC (β = -1.66, 95% CI: -1.53 to -1.02, p = 0.031) and ACL-QOL (β = -1.25, 95% CI: -1.61 to 1.02, p = n.s.). However, these associations indicated small, clinically insignificant changes based on reported measures of clinical relevance. Other important predictors of post-operative PROMs included age, sex, and baseline scores. Medial meniscus excision and lateral meniscus treatment (repair or excision) did not have an important influence on PROMs. There was no significant association between meniscal treatment and graft rupture or rotatory knee laxity.

CONCLUSION

While repairing the medial meniscus may result in a small reduction in PROM scores at two-year follow-up, these differences are not likely to be important to patients or clinicians. Any surgical morbidity associated with meniscal repair appears negligible in terms of PROMs. Meniscal repair does not affect rotatory laxity or graft failure rates in the short term. Therefore, meniscal repair should likely be maintained as the standard of care for concomitant meniscal tears with ACLR.

CPX-351 Yields Similar Response and Survival Outcome in Younger and Older Patients With Secondary Acute Myeloid Leukemia

BACKGROUND

CPX-351 was approved by the FDA in 2017 as frontline induction chemotherapy for patients aged ≥18 years with newly diagnosed acute myeloid leukemia (AML) which includes myelodysplasia-related changes (AML-MRC) and therapy-related acute myeloid leukemia (t-AML). The efficacy of CPX-351 among younger patients (aged <60 years) is currently unclear, as the large, randomized phase 3 study that led to approval of CPX-351 only included patients between the ages of 60 and 75 years.

METHODS

We performed a retrospective study of clinical and molecular data from adult patients with newly diagnosed AML-MRC or t-AML treated with CPX-351. Patients were divided into 2 cohorts: aged <60 years (cohort A) and aged ≥60 years (cohort B). We compared overall response rate (ORR) and median overall survival (mOS) between the cohorts.

RESULTS

Of 169 evaluable patients, 21.3% were in cohort A and 78.7% were in cohort B. ORR of the entire cohort was 53.3%; ORR of cohort A was 47.2% compared with 54.9% for cohort B (P = .46). Overall, 54.4% of responding patients proceeded to allogenic stem cell transplant (allo-SCT), including 52.9% of patients in cohort A and 54.8% in cohort B (P = 1.00). At a median follow-up of 24 months, mOS of the entire cohort was 16 months and was similar between cohorts A and B (18 vs. 15 months, respectively; P = .29).

CONCLUSION

CPX-351 resulted in similar response rates and survival outcomes among both younger and older adult patients with newly diagnosed AML-MRC or t-AML.

Comparison of tobacco and alcohol consumption in young and older patients with oral squamous cell carcinoma: a systematic review and meta-analysis

OBJECTIVE

To compare the proportion of young (up to 45 years of age) and older (over 45 years of age) oral squamous cell carcinoma (OSCC) patients who report tobacco and alcohol consumption.

METHODS

Observational studies reporting tobacco and alcohol consumption among young and older OSCC patients were selected in a two-phase process. Search strategies were conducted on five main electronic databases and complemented by grey literature. The risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Studies Reporting Prevalence Data. Synthesis of results was calculated with the software R Statistics version 4.0.2 (The R Foundation).

RESULTS

From 6675 records identified, 38 studies met the eligibility criteria and were selected for qualitative synthesis and meta-analysis, encompassing 2439 young and 13,393 older patients. Tobacco smoking was reported by 39.5% (confidence interval (CI) = 31.7% to 47.9%, I² = 78%) of the young patients and 48.4% (CI = 37.8% to 59.2%, I² = 94%) of the older patients. Alcohol consumption was reported by 30.9% (CI = 22.7% to 40.5%, I² = 83%) of the young and 45.8% (CI = 35.6% to 56.5%, I² = 95%) of the older patients (P < 0.05).

CONCLUSION

The comparison in the proportion of individuals reporting tobacco and alcohol consumption demonstrated that these habits were more prevalent in the older group (48.4% and 45.8% respectively) than in the young group (39.5% and 30.9%, respectively).

CLINICAL RELEVANCE

As a significant proportion of patients with OSCC reported no habits, novel risk factors for OSCC need to be investigated in further research.

Oral Squamous Cell Carcinoma Frequency in Young Patients from Referral Centers Around the World

Oral squamous cell carcinoma (OSCC) commonly affects older patients; however, several studies have documented an increase in its incidence among younger patients. Therefore, it is important to investigate if this trend is also found in different geographic regions. The pathology files of diagnostic and therapeutic institutions from different parts of the globe were searched for OSCC cases diagnosed from 1998 to 2018. Data regarding the sex, age, and tumor location of all cases, as well as the histologic grade and history of exposure to risk habits of cases diagnosed as OSCC in young patients (≤ 40 years of age) were obtained. The Chi-square test was used to determine any increasing trend. A total of 10,727 OSCC cases were identified, of which 626 cases affected young patients (5.8%). Manipal institution (India) showed the highest number of young patients (13.2%). Males were the most affected in both age groups, with the tongue and floor of the mouth being the most affected subsites. OSCC in young individuals were usually graded as well or moderately differentiated. Only 0.9% of the cases occurred in young patients without a reported risk habit. There was no increasing trend in the institutions and the period investigated (p > 0.05), but a decreasing trend was observed in Hong Kong and the sample as a whole (p < 0.001). In conclusion there was no increase of OSCC in young patients in the institutions investigated and young white females not exposed to any known risk factor represented a rare group of patients affected by OSCC.

Short neck-preserving femoral stem for total hip arthroplasty: medium-term results of a 68-case series

INTRODUCTION

Short stems seem to be a good alternative for young patients as they offer promising results, rapid recovery and preservation of metaphyseal bone stock. This is one of the few studies in the literature to report medium-term clinical-radiological results for short hip stems.

MATERIALS AND METHODS

This prospective study evaluated 68 short femoral stems in 63 patients treated with total hip replacement. Clinical, functional and quality-of-life outcomes were measured at 6 and 12 months, and annually thereafter until the end of follow-up. The radiological analysis included measurements of potential leg length discrepancies, stem alignment and signs compatible with stress shielding.

RESULTS

Fifty-four males (59 hips) and nine females (9 hips) of an average age of 44.3 years (range, 25-68) were studied. The most common diagnosis was osteoarthritis (51.5%). Mean overall follow-up was 7.8 years (range, 5.8-9.8). The overall survival rate was 97.1% (95% CI 88.7-99.7%). Surgery resulted in an increase of 42.3 ± 1.1 points in the modified Harris Hip Score and 21.9 ± 0.6 points in the Oxford Hip Score (p < 0.001, respectively). Moreover, the pain score as measured on a numerical rating scale (NRS) improved from 95.8 to 36.3. As regards function, an improvement was observed from 3.2 ± 0.8 points to 6.8 ± 1.14 points on the University of California at Los Angeles activity score (p < 0.001, respectively). The radiological analysis showed an absence of radiolucencies or stress-shielding throughout the series. The complications rate at the end of follow-up was 5.7%.

CONCLUSIONS

The use of ultra-short cylindrical stems with complete anchorage in the femoral neck was shown to offer promising medium-term results. Such stems appear to be a good option for young patients, who are likely to require several revisions over their lifetime.

Risk factors profile of young and older patients with myocardial infarction

Myocardial infarction (MI) among young adults (<45 years) represents a considerable proportion of the total heart attack incidents. The underlying pathophysiologic characteristics, atherosclerotic plaque features, and risk factors profile differ between young and older patients with MI. This review article discusses the main differences between the younger and elderly MI patients as well as the different pathogenic mechanisms underlying the development of MI in the younger. Young patients with MI often have eccentric atherosclerotic plaques with inflammatory features but fewer lesions, and are more likely to be smokers, obese, and have poor lifestyle, such as inactivity and alcohol intake. Compared to older MI patients, younger are more likely to be men, have familial-combined hyperlipidaemia and increased levels of lipoprotein-a. In addition, MI in younger patients may be related to use of cannabis, cocaine use, and androgenic anabolic steroids. Genomic differences especially in the pathways of coagulation and lipid metabolism have also been identified between young and older patients with MI. Better understanding of the risk factors and the anatomic and pathophysiologic processes in young adults can improve MI prevention and treatment strategies in this patient group. Awareness could help identify young subjects at increased risk and guide primary prevention strategies. Additional studies focusing on gene pathways related to lipid metabolism, inflammation, and coagulation are needed.

Minimally invasive Oxford medial unicompartmental knee replacement in patients 50 years of age or younger

INTRODUCTION

The aim of the present study was to assess clinical outcome and mid-term survivorship of mobile-bearing unicompartmental knee arthroplasty in patients 50 years of age or younger.

METHODS

This study reports the results of 119 patients (130 knees) following mobile-bearing medial UKA. Primary indication was advanced osteoarthritis or avascular necrosis of the femoral condyle. The anterior cruciate ligament (ACL) as well as the collateral ligaments were functionally intact, the varus deformity was manually correctable and there was no evidence of osteoarthritis in the lateral compartment. Survivorship analysis was performed with different endpoints and clinical outcome was measured using the Oxford Knee Score (OKS), American Knee Society Score and Functional Score (AKSS-O, AKSS-F), range of motion (ROM), Tegner activity score, University of California Los Angeles score (UCLA) and visual analogue scale for pain (VAS).

RESULTS

The survival rate was 96.6% at 6.5 years (95% CI 98.7-91.3%; number at risk: 56) and 91.7% (95% CI 96.7-80%; number at risk: 22) at 10 years for the endpoint device related revisions and 91.5% at 6.5 years (95% CI 95.4-84.5%; number at risk: 56) and 86.8% (95% CI 93-76.2%; number at risk: 22) at 10 years for the endpoint revision for any reason. Outcome scores, VAS and ROM showed significant improvements (p < 0.001). The mean OKS increased from 26.7 (standard deviation (sd): 7.2) preoperatively to 40.9 (sd: 7.6) at final follow-up, the mean AKSS-O from 48.3 (sd: 13.3) to 87.8 (sd: 14.4) and the mean ROM from 118° (sd: 16.7) to 125° (sd: 11.4). The radiological analysis revealed progression of degenerative changes in the lateral compartment in 39.6% of patients without affecting the functional outcome.

CONCLUSIONS

Medial mobile-bearing UKA is a viable surgical treatment option in young patients with significant improvements in knee function and pain. Further follow-up is necessary to evaluate the long-term efficacy.

Outcomes of Endovascular Therapy in Young Patients with Acute Basilar Artery Occlusion: A Substudy of BASILAR Registry Study

INTRODUCTION

This study aimed to investigate clinical outcomes in young patients with basilar artery occlusion (BAO) receiving endovascular therapy (EVT).

METHODS

Consecutive patients with BAO within 24 h who underwent EVT from the BASILAR Registry study were enrolled. We compared clinical outcomes of young patients (aged 18-55 years) with older patients (aged > 55 years) with stroke due to BAO at 90 days and 1 year after EVT. The primary and secondary outcomes were improvement in modified Rankin scale scores (mRS) at 90 days and either favorable (mRS 0-3) or mortality at 90 days, respectively.

RESULTS

A total of 646 patients were included, of which 152 (23.53%) were aged 18-55 years. Dyslipidemia (42.11% vs. 30.36%, p = 0.007) and good collateral circulation (60.52% vs. 46.35%, p = 0.002) were more frequent in young patients than older. Stroke etiologies in young patients included large artery atherosclerosis (67.11%), cardioembolism (15.13%), and vessel dissection (5.26%). Young patients were associated with better prognosis (mRS: adjusted odds ratio (aOR) 1.73; 95% confidence interval [CI] 1.21-2.48; mRS 0-3: aOR 1.60; 95% CI 1.01-2.54; mortality: aOR 0.60; 95% CI 0.38-0.93) at 90 days. Baseline National Institutes of Health Stroke Scale (NIHSS) score, posterior circulation Alberta Stroke Program Early Computed Tomography Score (pc-ASPECTS), and sex were independent predictors of clinical outcomes of young patients at 90 days after EVT.

CONCLUSION

Young patients with BAO had better clinical outcomes after EVT than old patients. Predictors of clinical outcomes in young patients undergoing EVT included baseline NIHSS score, pc-ASPECTS, and sex.

Clinical Features of Central Retinal Vein Occlusion in Young Patients

Retinal vein occlusion (RVO) is the second most common retinal vascular disease. Central RVO (CRVO), in which obstruction occurs posterior to the lamina cribrosa due to various causes, manifests with extensive venous tortuosity, dilatation of blood vessels in the four quadrants, and retinal hemorrhage. The presence of macular edema decreases visual acuity in patients with CRVO, especially in elderly patients with hypertension, hyperlipidemia, and diabetes. In the last decade, treatment modalities for CRVO have improved, with anti-vascular endothelial growth factor agents being widely used as treatment. However, there are cases of refractory or recurrent macular edema. Moreover, CRVO also occurs in young patients. This article reviews previous studies and case reports and summarizes the differences in etiological factors, clinical manifestations, treatment, and prognosis between young and elderly patients. Due to the low incidence of CRVO in young patients, clinical data from these age groups are limited. Hence, further studies are warranted to explore the differences between age groups to improve individualization of treatment of young patients.

T2 mapping for knee cartilage degeneration in young patients with mild symptoms

BACKGROUND

We aimed to analyze the distribution of knee cartilage degeneration in young patients with mild symptoms using quantitative magnetic resonance imaging (MRI) T2 mapping.

MATERIALS AND METHODS

This study included sixty six patients (case group) and twenty eight healthy volunteers (control group). The participants underwent 3.0 T conventional MRI plus a multi-echo sequence. The cartilage of each participant was divided into twenty eight subregions. We then calculated the T2 mean values and standard deviation or median and quartile range for each subregion according to whether the normal distribution was satisfied. Besides, we employed Kruskal-Wallis test to determine the statistical differences of each subregion in the control group while the Mann-Whitney U test was used to define the statistical difference between the case group and the control group and between the control group and subjects aged less than or equal to 35 years in the case group.

RESULTS

In the case group, age of 30 male patients was 31.5 ± 9.3 and age of 36 female patients was 35.7 ± 8.3. In the two groups, the superficial central lateral femoral region exhibited relatively high T2 values (control/case group: 49.6 ± 2.7/55.9 ± 8.8), and the deep medial patellar region exhibited relatively low T2 values (control/case group: 34.2 ± 1.3/33.5(32.2, 35.5)). Comparison of the T2 values between the case and the control group demonstrated a statistically significant increase in nine subregions (P₁ < 0.05) and there were five subregions in the case group with age ≤ 35 years (P₂ < 0.05). In particular, the p-values for four subregions of the patellofemoral joint were all less than 0.05 (P₁ = 0.002, 0.015, 0.036, 0.005).

CONCLUSION

T2 values of patients were significantly different with values of healthy groups, especially in the superficial cartilage of the patellofemoral joint. It made T2 mapping helpful to early identify patients with knee cartilage degeneration.

Characteristics of primary signet ring cell carcinoma of colon and rectum: a case control study

Background

Primary signet ring cell carcinoma of the colon and rectum (PSRCCR) is rare, usually diagnosed at advanced stage with poor outcomes. We aimed to find possible diagnostic clues in order to help diagnosis.

Methods

A retrospective study of PSRCCR patients from 1993 to 2018 was reviewed at a single tertiary center. Colorectal adenocarcinoma patients as control group with 1:4 ratio was also enrolled.

Results

18 patients with PSRCCR were identified. The prevalence rate was 0.16% (18 of 11,515). The mean age was 50.2 years-old in PSRCCR group and 63 years-old in non-SRCC colorectal cancer patients (p < 0.001). Diagnosis tool depends on colonoscopy were much less in PSRCCR group than control group (44.4% vs 93%, p < 0.001). SRCC patients had higher level of CEA (68.3 vs 17.7 ng/mL, p = 0.004) and lower level of Albumin (3.4 vs 4.3 g/dL, p < 0.001). The majority of PSRCCR tumor configuration was ulcerative and infiltrative. More PSRCCR pathology presented as high-grade carcinoma (66.7 vs 1.4%, p < 0.001) and lymphovascular invasion (77.8 vs 44.4%, p = 0.011) than control group. More PSRCCR patients were diagnosed at advanced stage (88.8 vs 40.3%, p = 0.001). Higher mortality was also noticed in PSRCCR group than control group (72.2 vs 20.8%, p < 0.001).

Conclusion

For young patients with long segment colonic stenosis and ulcerative/ infiltrative mucosa but endoscopic biopsy failed to identify malignant cells, earlier operation or non-colon site biopsy is suggested for diagnosing the PSRCCR.

The ocular biometry characteristics of young patients with primary angle-closure glaucoma

Background

Although primary angle-closure glaucoma (PACG) mainly occurs in elderly people, diagnosis of PACG in young patients is not uncommon. So far, there is no article specialized on the ocular anatomical characteristics in these patients.In this study, ocular anatomical characteristics in young PACG patients are analyzed.

Methods

In this retrospective, comparative study, patients diagnosed with PACG and received ultrasound biomicroscopy (UBM) examination in our department were included. Patients were divided into two groups: a young group composed of patients ≤ 45 years and an old group composed of patients > 45 years. A-scan ultrasonography and ultrasound biomicroscopy (UBM) were used to measure ocular biometric parameters of patients in the two groups including axial length (AL), lens thickness (LT), central anterior chamber depth (ACD), anterior chamber width (ACW), angle opening distance 500 (AOD500), anterior chamber angle 500 (ACA500), iris thickness 1000 μm from the iris root (IT1000), iris thickness 500 μm from the iris root (IT500), trabecular-ciliary process angle (TCPA), trabecular-ciliary process distance (TCPD), scleral– ciliary process angle (SCPA), lens vault (LV), and pupil diameter (PD). Plateau iris (PI) and basal iris insertion were determined from UBM images, and the prevalence of PI and basal iris insertion were compared between the two groups. The incidence of postoperative malignant glaucoma (MG) was also determined in both groups and ocular anatomical predictors for the development of MG were evaluated in young PACG patients.

Results

One hundred fifteen patients were included into young group and 480 patients were included into old group. The young group had shorter TCPD, shorter AL, narrower TCPA, narrower SCPA thinner Lens compared to the old group. There were no significant differences in ACD, AOD 500, ACA500, LV, IT500, IT1000, PD or ACW between the two groups. The prevalence of PI was 22.6% in old group and 66.1% in young group (P < 0.001). More young PACG patients displayed basal iris insertion compared to old PACG patients (P < 0.001). 87 patients in the young group and 201 patients in the old group underwent trabeculectomy in our study. Among these patients, 21 young patients and 11 old patients developed MG after trabeculectomy (P < 0.001).

Conclusions

Shorter AL, more anteriorly positioned ciliary body, higher prevalence of PI may be responsible for the etiology of young PACG patients. Our results suggest that shorter AL, shorter TCPD and narrower TCPA may be predictors for development of MG in young PACG patients after trabeculectomy.

Incidence trends and long-term outcomes of myocardial infarction in young adults: Does gender matter?

AIMS

Data about long-term clinical outcomes of young patients experiencing an acute myocardial infarction (MI) and about the potential impact of gender on juvenile MI incidence and prognosis are scant.

METHODS AND RESULTS

Hospital Discharge Register records of Piedmont region (Italy) from 2007 to 2018 were interrogated to identify incident juvenile MI cases and MI recurrences. Patients were considered young if the first MI occurred before or at 47 years of age (5th percentile). Incidence of first juvenile MI event and overall survival were the primary outcomes. Gender differences and survival rate after an MI recurrence were secondary outcomes. Out of 114.816 hospitalizations due to MI, 4482 (3.9%) occurred in people aged ≤47. Average incidence rate of juvenile MI over the study period was 24.5 (23.8-25.2) per 100.000 person-years, with a decline among men and a stable trend among women through the years. The risk of in hospital death was higher for women (1.9% vs. 0.9%, p = 0.02), while the survival rate at 10 years after the first MI was 94.8%, without gender differences (HR 1.05: 0.69-1.60). MI recurrence occurred in 348 (7.8%) and was less common in women (HR 0.72: 0.52-0.99). After multivariate adjustment, MI recurrence was associated with a significantly higher risk of death at follow-up as compared with a single MI episode (HR 3.05: 1.9-4.80, all CI 95%).

CONCLUSION

Among young patients with MI, women had a higher in-hospital mortality compared to men, but long-term prognosis after hospital discharge did not differ. MI recurrences were associated with increased mortality at follow up.

The outcome of subsequent revisions after primary total hip arthroplasty in 1,049 patients aged under 50 years : a single-centre cohort study with a follow-up of more than 30 years

AIMS

The aim of this study was to determine the outcome of all primary total hip arthroplasties (THAs) and their subsequent revision procedures in patients aged under 50 years performed at our institution.

METHODS

All 1,049 primary THAs which were undertaken in 860 patients aged under 50 years between 1988 and 2018 in our tertiary care institution were included. We used cemented implants in both primary and revision surgery. Impaction bone grafting was used in patients with acetabular or femoral bone defects. Kaplan-Meier analyses were used to determine the survival of primary and revision THA with the endpoint of revision for any reason, and of revision for aseptic loosening.

RESULTS

The mean age of the patients at the time of the initial THA was 38.6 years (SD 9.3). The mean follow-up of the THA was 8.7 years (2.0 to 31.5). The rate of survival for all primary THAs, acetabular components only, and femoral components only at 20 years' follow-up with the endpoint of revision for any reason, was 66.7% (95% confidence interval (CI) 60.5 to 72.2), 69.1% (95% CI 63.0 to 74.4), and 83.2% (95% CI 78.1 to 87.3), respectively. A total of 138 revisions were performed. The mean age at the time of revision was 48.2 years (23 to 72). Survival of all subsequent revision procedures, revised acetabular, and revised femoral components at 15 years' follow-up with the endpoint of revision for any reason was 70.3% (95% CI 56.1 to 80.7), 69.7% (95% CI 54.3 to 80.7), and 76.2% (95% CI 57.8 to 87.4), respectively. A Girdlestone excision arthroplasty was required in six of 860 patients (0.7%).

CONCLUSION

The long-term outcome of cemented primary and subsequent revision THA is promising in these young patients. We showed that our philosophy of using impaction bone grafting in patients with acetabular and femoral defects is a very suitable option when treating young patients. Surgeons should realize that knowledge of the outcome of subsequent revision surgery, which is inevitable in young patients, must be communicated to this group of patients prior to their initial THA.

Complex proximal femoral fracture in a young patient followed up for 3 years: A case report

BACKGROUND

Ipsilateral femoral neck and intertrochanteric fractures in young patients are extremely rare, and there is no reference for fracture classification and treatment options.

CASE SUMMARY

We report a 27-year-old male patient who sustained ipsilateral femoral neck and intertrochanteric fractures and was treated with a proximal femoral locking compression plate (PFLCP). The literature on these fractures was also reviewed. At the last follow-up three years after surgery, the patient had no obvious pain in the hip, and the range of motion in the hip joint was slightly limited, but met the normal life and work needs. There were no complications such as necrosis of the femoral head.

CONCLUSION

The PFLCP can be used to treat these complex proximal femoral fractures, and selection should be based on the patient's specific fractures.

Development and validation of a nomogram to predict overall survival in young non-metastatic rectal cancer patients after curative resection: a population-based analysis

PURPOSE

This study aimed to establish and validate a nomogram for predicting overall survival (OS) in young non-metastatic rectal cancer (RC) patients after curative resection.

METHODS

Young RC patients (under 50 years of age) from 2010 to 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Those patients randomly assigned to a training cohort and a validation cohort at a ratio of 7:3. The independent prognostic factors for OS were identified by univariate and multivariate Cox regression analysis. A nomogram model was built based on the independent prognostic variables and was evaluated by concordance index (C-index), receiver operating characteristics (ROC) curves, calibration plot, and decision curve analysis (DCA).

RESULTS

A total number of 3026 young RC patients were extracted from SEER database. OS nomogram was constructed based on race, histological type, tumor grade, T stage, N stage, carcinoembryonic antigen (CEA) level, and number of lymph nodes (LN) examined. C-index, ROC curves, calibration plot, and DCA curves presented satisfactory performance of the above nomogram in predicting the prognosis of young non-metastatic RC patients after curative resection. The nomogram can identify three subgroups of patients at different risks, which showed different prognostic outcomes both in the training cohort and validation cohort.

CONCLUSION

We successfully established a reliable and insightful nomogram to predict OS for young non-metastatic RC patients after curative resection. The nomogram may provide accurate prognosis prediction to guide individualized follow-up and treatment plans.
