RESUMEN
BACKGROUND: Neurological emergencies are one of the major diagnosis groups in the Emergency Medical Services (EMS) with the highest rate of misdiagnosis. Despite the knowledge of time sensitivity and the importance of prehospital factors, prehospital delay is common. Although several stroke triage scales have been developed, a gold standard in the prehospital setting is lacking. OBJECTIVES: Our aim was to evaluate the perception of neurological emergencies by EMS personnel and to identify current problems, difficulties and opportunities for improvement in the prehospital management of stroke, seizure, non-specific neurological symptoms, and paediatric neurological emergencies. METHODS: The study was conducted as an online survey through SoSci Survey and was made available from March 1st to June 30th 2023 to all personnel working in emergency medical services. The access link was distributed through snowballing, social media, and through a QR code on a promotional poster. The survey was completed anonymously. The final survey consisted of 30 questions in German on the topics of neurological emergencies, general neurological assessment, specific neurological examination including paediatric assessment, stroke, and seizures, and finally suggestions for improvement. RESULTS: The largest group of participants were paramedics, who estimated to encounter neurological emergencies at a general rate of 20-60%. When unease was felt, the main reasons were ambiguity of symptoms and insufficient admission capacity of hospitals. The biggest challenges were highly varied. Almost 80% of participants assumed that the neurological assessment would be omitted in difficult patient groups such as demented, intoxicated or children. 75% felt uncomfortable making a paediatric assessment, 50% were unfamiliar with the Paediatric Glasgow Coma Scale. CONCLUSIONS: Support through more standardized practical training and defined, uniform guidelines is needed. There was also a clear need for peer collaboration, feedback and case sharing. Digitalization, the usage of telemedicine and updated versions of the documentation protocols including paediatric adaptations to current guidelines could further improve current neurological assessment in the prehospital setting.

BACKGROUND: Sentinel lymph node biopsy (SLNB) has replaced axillary lymph node dissection (ALND) for assessing axillary lymph node status in clinically node-negative breast cancer patients. However, the approach to axillary surgery after neoadjuvant treatment is still controversial. In the present study, our objective was to predict the pathological nodal stage based on SLNB results and the clinicopathological characteristics of patients who initially presented with clinical N1 positivity but whose disease status was converted to clinical N0 after neoadjuvant chemotherapy (NAC). MATERIALS AND METHODS: After NAC, 150 clinically node-negative patients were included. The relationships between clinicopathologic parameters and the number of positive lymph nodes in SLNBs and ALNDs were assessed through binary/multivariate logistic regression analysis. RESULTS: Among 150 patients, 78 patients had negative SLNBs, and 72 patients had positive SLNBs. According to the ALND data of 21 patients with SLNB1+, there was no additional node involvement (80.8%), 1-2 lymph nodes were positive in 5 patients (19.2%), and no patient had ≥ 3 lymph nodes involved. Following the detection of SLNB1 + positivity, the rate of negative non-sentinel nodes were 75% in the luminal A/B subgroup, 100% in the HER-2-positive subgroup, and 100% in the triple-negative subgroup. Patients with a lower T stage (T1-3 vs. T4), fewer than 4 clinical nodes before NAC (< 4 vs. ≥4), and a decreased postoperative Ki-67 index (< 10% vs. stable/increase) were included. According to both univariate and multivariate analyses, being in the triple-negative or HER2-positive subgroup, compared to the luminal A/B subgroup (luminal A/B vs. HER2-positive/triple-negative), was found to be predictive of complete lymph node response. CONCLUSION: The number of SLNB-positive nodes, tumor-related parameters, and response to treatment may predict no additional nodes to be positive at ALND.

Our aim was to assess the efficacy of adjuvant programmed cell death protein-1 (PD-1) inhibitors and compare the other adjuvant treatments in patients with surgically resected stage III or IV acral melanoma. This study is a multicenter, retrospective analysis. We included 114 patients with stage III or IV acral malignant melanoma who underwent surgery within the past 10 years. We analyzed the effect of adjuvant programmed cell death protein-1 inhibitors on disease-free survival (DFS). The mean follow-up was 40 months, during which 69 (59.5%) patients experienced recurrence. Among the participants, 64 (56.1%) received systemic adjuvant therapy. Specifically, 48.4% received anti-PD-1 therapy, 29.7% received interferon, 14.1% received tezozolomide, and 7.8% received B-Raf proto-oncogene/mitogen-activated protein kinase inhibitors. Patients who received adjuvant therapy had a median DFS of 24 (10.9-37.2) months, whereas those who did not receive adjuvant therapy had a median DFS of 15 (9.8-20.2) months. Multivariate analysis for DFS revealed that the receipt of adjuvant therapy and lymph node metastasis stage were independent significant parameters ( P = 0.021, P = 0.018, respectively). No statistically significant difference was observed for DFS between programmed cell death protein-1 inhibitor treatment and other adjuvant treatments. Regarding overall survival (OS), patients who received adjuvant treatment had a median OS of 71 (30.4-111.7) months, whereas those who did not receive adjuvant treatment had a median OS of 38 (16.7-59.3; P = 0.023) months. In addition, there were no significant differences in OS observed between various adjuvant treatment agents ( P = 0.122). In our study, we have shown that adjuvant therapy had a positive effect on both DFS and OS in patients with stages III-IV acral melanoma who underwent curative intent surgery. Notably, we found no significant differences between anti-PD-1 therapy and other adjuvant therapies.

We report here a 46-year-old male patient with a 14 cm segmental bone defect of the radial shaft after third degree open infected fracture caused by a shrapnel injury. The patient underwent fixed-angle plate osteosynthesis and bone reconstruction of the radial shaft by a vascularized 3D-printed graft cage, including plastic coverage with a latissimus dorsi flap and an additional central vascular pedicle. Bony reconstruction of segmental defects still represents a major challenge in musculo-skeletal surgery. Thereby, 3D-printed scaffolds or graft cages display a new treatment option for bone restoration. As missing vascularization sets the limits for the treatment of large-volume bone defects by 3D-printed scaffolds, in the present case, we firstly describe the reconstruction of an extensive radial shaft bone defect by using a graft cage with additional vascularization.
RESUMEN
BACKGROUND: Coagulopathy is prevalent in multiple trauma patients and worsens bleeding complications, leading to higher morbidity and mortality rates. Hyperglycemia upon admission predicts hemorrhagic shock and mortality in severely injured patients. This study aimed to assess admission glucose levels as an independent prognostic factor for coagulopathy in multiply injured patients. METHODS: This retrospective cohort study observed multiple trauma patients treated at a level I trauma center between January 1, 2005, and December 31, 2020. Coagulopathy was defined as an international normalized ratio (INR) > 1.4 and/or activated thromboplastin time (APTT) > 40 s. Analysis of variance compared clinical and laboratory parameters of patients with and without coagulopathy. Receiver-operating-characteristic (ROC) and multivariate logistic regression analyses identified risk factors associated with coagulopathy. RESULTS: The study included 913 patients, of whom 188 (20%) had coagulopathy at admission. Coagulopathy patients had higher mortality than those without (26% vs. 5.0%, p < 0.001). Mean glucose level in coagulopathy patients was 10.09 mmol/L, significantly higher than 7.97 mmol/L in non-coagulopathy patients (p < 0.001). Admission glucose showed an area under the curve (AUC) of 0.64 (95% CI [0.59-0.69], p < 0.001) with an optimal cut-off point of 12.35 mmol/L. After adjusting for other factors, patients with high admission glucose had a 1.99-fold risk of developing coagulopathy (95% CI 1.07-3.60). Other laboratory parameters associated with coagulopathy included haemoglobin, bicarbonate (HCO3), and lactate levels. CONCLUSION: This study emphasizes the significance of admission blood glucose as an independent predictor of coagulopathy. Monitoring hyperglycemia can aid in identifying high-risk patients.
RESUMEN
INTRODUCTION: The increasing socioeconomic need for optimal treatment of hip fractures in combination with the high diversity of available implants has raised numerous biomechanical questions. This study aims to provide a comprehensive overview of biomechanical research on the treatment of intertrochanteric fractures using cephalomedullary devices. METHODS: Following the PRISMA-P guidelines, a systematic literature search was performed on 31.12.2022. The databases PubMed/MEDLINE and Web of Science were searched. Scientific papers published between 01.01.2000 - 31.12.2022 were included when they reported data on implant properties related to the biomechanical stability for intertrochanteric fractures. Data extraction was undertaken using a synthesis approach, gathering data on criteria of implants, sample size, fracture type, bone material, and study results. RESULTS: The initial search identified a total of 1459 research papers, out of which forty-three papers were considered for final analysis. Due to the heterogeneous methods and parameters used in the included studies, meta-analysis was not feasible. A comprehensive assessment of implant characteristics and outcome parameters was conducted through biomechanical analysis. Various factors such as proximal and distal locking, nail diameter and length, fracture model, and bone material were thoroughly evaluated. CONCLUSION: This scoping review highlights the need for standardization in biomechanical studies on intertrochanteric fractures to ensure reliable and comparable results. Strategies such as avoiding varus, maintaining a sufficient tip-apex-distance, cement augmentation, and optimizing lesser trochanteric osteosynthesis enhance construct stability. Synthetic alternatives may offer advantages over cadaveric bone. Further research and meta-analyses are required to establish standardized protocols and enhance reliability.

Importance: Cancer was a common noncommunicable disease in Syria before the present conflict and is now a major disease burden among 3.6 million Syrian refugees in Turkey. Data to inform health care practice are needed. Objective: To explore sociodemographic characteristics, clinical characteristics, and treatment outcomes of Syrian patients with cancer residing in the southern border provinces of Turkey hosting more than 50% of refugees. Design, Setting, and Participants: This was a retrospective hospital-based cross-sectional study. The study sample consisted of all adult and children Syrian refugees diagnosed and/or treated for cancer between January 1, 2011, and December 31, 2020, in hematology-oncology departments of 8 university hospitals in the Southern province of Turkey. Data were analyzed from May 1, 2022, to September 30, 2022. Main Outcomes and Measures: Demographic characteristics (date of birth, sex, and residence), date of first cancer-related symptom, date and place of diagnosis, disease status at first presentation, treatment modalities, date and status at last hospital visit, and date of death. The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision and International Classification of Childhood Cancers, Third Edition, were used for the classification of cancer. The Surveillance, Epidemiology, and End Results system was applied for staging. The diagnostic interval was defined as the number of days from first symptoms until the diagnosis. Treatment abandonment was documented if the patient did not attend the clinic within 4 weeks of a prescribed appointment throughout the treatment. Results: A total of 1114 Syrian adult and 421 Syrian children with cancer were included. The median age at diagnosis was 48.2 (IQR, 34.2-59.4) years for adults and 5.7 (IQR, 3.1-10.7) years for children. The median diagnostic interval was 66 (IQR, 26.5-114.3) days for adults and 28 (IQR, 14.0-69.0) days for children. Breast cancer (154 [13.8%]), leukemia and multiple myeloma (147 [13.2%]), and lymphoma (141 [12.7%]) were common among adults, and leukemias (180 [42.8%]), lymphomas (66 [15.7%]), and central nervous system neoplasms (40 [9.5%]) were common among children. The median follow-up time was 37.5 (IQR, 32.6-42.3) months for adults and 25.4 (IQR, 20.9-29.9) months for children. The 5-year survival rate was 17.5% in adults and 29.7% in children. Conclusions and Relevance: Despite universal health coverage and investment in the health care system, low survival rates were reported in this study for both adults and children with cancer. These findings suggest that cancer care in refugees requires novel planning within national cancer control programs with global cooperation.

Extensive diaphyseal and metaphyseal bone defects continue to pose a major challenge for orthopedic trauma surgeons. Various treatment options have been described for the biological reconstruction of these defects. The most frequently used methods are bone segment transport, the Masquelet technique and 3D printed scaffolds. As far as the Masquelet technique is concerned, in the first stage spacers, such as polymethyl methacrylate (PMMA), calcium sulfate or polypropylene are inserted into the bone defects to induce a foreign body membrane. In the second stage the bone defect surrounded by the induced membrane is filled with autologous cancellous bone. The time interval between the first and second interventions is usually 4-8 weeks whereby the induced membranes do not lose their bioactivity even with a latency period longer than 8 weeks. Three-dimensional printed scaffolds are increasingly used but large clinical studies are lacking in order to show the exact role of this procedure in the reconstruction of bone defects.

Aim: Vitamin D has a role in carcinogenesis and may have effect on recurrence. Thus, we aim to analyze the prognostic effect of vitamin D levels at beginning and follow-up together with the contribution of vitamin D supplementation on patients with colorectal cancer (CRC). Materials & methods: CRC patients who underwent curative surgery were included. Patients' vitamin D values were assessed under four groups according to baseline and follow-up vitamin D values, and whether vitamin D supplementation was used. Survival distributions were compared for vitamin D groups. Results: Patients with a high follow-up vitamin D level and a high vitamin D level after supplementation presented with better disease-free survival and overall survival than patients with low vitamin D and low vitamin D levels after supplementation. Conclusion: Follow-up vitamin D values seems to be a good predictive biomarker and vitamin D supplementation may have a positive effect on survival.

PURPOSE: In this study, we aimed to investigate the utilization of 68Ga-FAPI PET/CT in comparison to 18FDG PET/CT to evaluate the peritoneal involvement of the gastrointestinal malignancies alongside primary lesions and other metastatic foci. PROCEDURES: A total of 37 patients with various gastrointestinal malignancies with accompanying peritoneal involvement who underwent 68Ga-FAPI PET/CT and 18FDG PET/CT imaging between September 2020 and June 2021 were included in this retrospective study. SUVmax values of 68Ga-FAPI and 18FDG were compared according to lesion locations. Also, the lesion localization ability of both imaging was compared in patient basis. RESULTS: Of the 37 patients with peritoneal involvement (23 males and 14 females; median age, 62.8 ± 12.7 years), 35.1% (n = 13) had colorectal cancer, 37.8% (n = 14) gastric cancer, and 27.0% (n = 10) pancreaticobiliary cancer. While 45.9% of them were operated, the remaining did not have surgery. The mean time interval between two studies was 3.2 days (range: 2-6 days). The mean SUVmax value of peritoneal metastases (p < 0.001) was significantly higher with 68Ga-FAPI PET/CT compared to that with 18FDG PET/CT, as in primary lesions (p < 0.001), lymph node metastases (p = 0.006), liver metastases (p = 0.002), and bone metastases (p = 0.018). A total of 185 lesions was detected in the initial assessment with 18FDG PET/CT. Of the total lesions detected with 18FDG PET/CT, 5 of them were evaluated as benign lesions with 68Ga-FAPI PET/CT also in accordance with the reference standard. In addition to 180 lesions detected with 18FDG PET/CT, a total of 37 additional malignant lesions, 12 of which were peritoneal metastases, were detected with 68Ga-FAPI PET/CT. CONCLUSION: 68Ga-FAPI PET/CT was determined to be superior to 18FDG PET/CT in terms of detection of peritoneal involvement with high image quality as well as primary tumor and other metastatic foci. Consequently, 68Ga-FAPI PET/CT can be used as a complementary imaging modality especially for inconclusive 18FDG findings due to the lack of accuracy of 18FDG PET/CT in some of the metastatic regions, especially in the liver.

Rearrangements of the anaplastic lymphoma kinase (ALK) gene are present in 3-5% of non-small-cell lung cancer (NSCLC), while it was 0.2% in NSCLC tumors. Due to its low frequency, it is extremely challenging to conduct randomized clinical trials of ALK-targeted therapies in NSCLC tumors. In the present case, we describe the first reported case of triple-negative breast cancer (TNBC) harboring the ALK fusion mutation that responded to ALK-targeted therapy after progression with two lines of chemotherapy. Searching for ALK gene rearrangement or other fusion, especially in patients with chemotherapy-resistant TNBC, opens the door to new treatment strategies.

OBJECTIVE: In this study, we aimed to compare [68Ga]FAPI PET/CT and [18F]FDG PET/CT imaging to detect lesions in multiple myeloma. METHODS: A total of 14 patients with multiple myeloma who underwent [68Ga]FAPI PET/CT and [18F]FDG PET/CT imaging were included in this retrospective study. SUVmax values of [68Ga]FAPI and [18F]FDG were compared according to lesion locations. Also, lesion localization ability of both imaging methods was compared on the patient basis. RESULTS: In 4 of 14 patients, [68Ga]FAPI PET/CT and [18F]FDG PET/CT have not detected any bone lesions. In 8 of the remaining 10 patients [18F]FDG PET/CT detected bone lesions but in this group, 6 patients showed more higher SUVmax values than [18F]FDG PET/CT in [68Ga]FAPI PET/CT.In contrast, 2 of 8 patients showed more higher SUVmax values than [68Ga]FAPI PET/CT in [18F]FDG PET/CT. Moreover, [68Ga]FAPI PET/CT detected bone lesions in two patients, which werenot detected by [18F]FDG PET/CT. Also, in five patients, [68Ga]FAPI PET/CT showed more bone lesions in comparison with[18F]FDG PET/CT. Only one patient, [18F]FDG PET/CT showed more bone lesions. Three extramedullary involvements were observed in the following locations: lung, presacral lymph node, and soft tissue mass lateral to the right maxillary sinus. Among these involvements, higher SUVmax values were observed in the lung and presacral lymph node with [68Ga]FAPI compared to [18F]FDG. However, the soft tissue mass showed a higher SUVmax value in [18F]FDG than [68Ga]FAPI. CONCLUSIONS: No significant superiority was observed in [68Ga]FAPI PET/CT over [18F]FDG PET/CT in patients with MM. However, [68Ga]FAPI PET/CT can be utilized as a complementary imaging method to [18F]FDG PET/CT in some settings, especially in low-[18F]FDG affinity and inconclusive cases. Considering the favorable aspects of [68Ga]FAPI PET/CT in MM, such as low background activity, absence of non-specific bone marrow, and physiological brain involvement, further studies with a larger sample size should be conducted.

PURPOSE: We compared the ability of 68Ga-FAPI PET//CT with 18FDG PET/CT imaging techniques to detect additional lesions in breast cancer patients that may affect further chemotherapy options. METHODS: A total of 48 patients with breast cancer underwent concurrent 68Ga-FAPI-04 and 18FDG PET/CT regardless of whether they had received chemotherapy or not in the last month before imaging. Both modalities were compared according to various parameters: clinical/pathological features, number of lesions detected, activity uptake (SUVmax), and the effect on the evaluation of response to treatment in the post-chemotherapy group. RESULTS: This retrospective study included 48 patients with breast cancer (mean age 53.3 ± 11.7 years; IDC 89.6%; ILC 10.4%). In the comparison of both modalities, no statistical significance was obtained in terms of the pathological characteristics of the patients. More lesions were demonstrated in all categorized regions in 68Ga-FAPI PET/CT imaging with higher uptake values compared to 18FDG PET/CT in this study. In the treatment response evaluation of the post-chemotherapy group, 12 cases (12/24) who were evaluated as PMR, CMR, or SD according to 18FDG PET/CT results were later accepted as PD due to newly detected lesions in complementary 68Ga-FAPI PET/CT imaging and treatment of patients was managed accordingly by clinicians. CONCLUSION: It was determined that 68Ga-FAPI PET/CT was superior to 18FDG PET/CT in terms of accuracy and it was thought that 68Ga-FAPI PET/CT could be utilized as an additional complementary imaging to 18FDG PET/CT. Moreover, 68Ga-FAPI PET/CT, with its significant theranostic potential, could become a key element in predicting the pathological response of breast cancer patients in further researches.

Tomografía Computarizada por Tomografía de Emisión de PositronesRESUMEN
Chemotherapy-induced nausea and vomiting (CINV) may be linked to the psychological status of cancer patients. Therefore, the authors aimed to better understand the underlying risk factors for CINV using the Brief Illness Perception Questionnaire. A total of 238 patients were recruited during three cycles of chemotherapy. Patient, disease and treatment characteristics were noted at the onset of chemotherapy. The Brief Illness Perception Questionnaire was administered face-to-face prior to chemotherapy. The relationship between illness perceptions and CINV was analyzed using Spearman's rank correlation. Positive illness perception parameters, including personal and treatment control, were negatively correlated, whereas negative illness perception parameters, including consequences, timeline, identity, concern and emotions, were positively correlated with CINV after adjusting for age, sex and emetogenic potential of chemotherapy (p < 0.001). Illness perception may be an underlying risk factor for CINV.

PURPOSE: The peritoneum is the common recurrence site of gastric cancer (GC) presenting with worse survival. Although some predictive clinicopathological factors have been identified, there is no comprehensive assessment of peritoneal recurrence risk prediction for patients treated with adjuvant chemotherapy (CR) or chemoradiotherapy (CRT) after surgery. We aimed to predict peritoneal recurrence and develop a new scoring model in GC. METHODS: This retrospective study included 274 GC patients who presented with recurrence after curative gastrectomy followed by adjuvant chemotherapy (CT) or chemoradiotherapy (CRT). Risk factors for peritoneal recurrence were analyzed using the following parameters: age, gender, tumor location and characteristics, and differences between treatment modalities. All parameters were assessed by binary logistic regression analysis to compare the patients with and without peritoneal recurrence. Then, a new risk scoring model was developed. RESULTS: Peritoneal recurrence was observed in 115 (44.1%) patients. Peritoneal recurrence was higher in female gender (odds ratio (OR), 1.93; 1.07-3.49, P = 0.030, 1 point), T4a-b stage (OR, 2.47; 1.14-5.36, P = 0.022, 1 point), poor/undifferentiated (OR, 2.04; 1.31-4.06, P = 0.004, 1 point), and signet cell carcinoma (OR, 2.04; 1.04-4.02, P = 0.038, 1 point) after adjusted for resection and dissection types. The risk scoring model was developed using the related parameters: Peritoneal recurrence rates were 24.6%, 42.6%, and 71.4% for group 1 (0 point), group 2 (1-2 points), and group 3 (3-4 points), respectively. CONCLUSION: Female gender, T4 tumor stage, undifferentiated histopathology, and signet cell type had a tendency to peritoneal recurrence after adjusted for treatment modalities. Patients with 3 or 4 risk factors had an 8.8-fold increased risk for the development of peritoneal recurrence.
