Identifying risk factors for fracture occurrence in breast cancer (BC) skeletal metastases (SM) may guide the management of such bone deposits. There is sparse evidence regarding receptor status in SM and their relationship to fracture occurrence. Our study aimed to determine the relationship between estrogen (ER), progesterone (PR) and HER2 receptor status and Ki-67 index and fracture occurrence in SM of BC. Exactly 152 samples of SM of BC obtained from individual patients were evaluated. The status of the aforementioned receptors and Ki67 index were determined in SMs samples. Their expression was compared between SM that did and did not develop a fracture. Ninety-one cases sustained a pathological fracture at the SM site, and 61 did not. Patients who sustained a pathological fracture had a higher rate of PR positivity at their SMs as compared to those with no fracture. There was no significant difference between the two groups concerning ER, HER2+ or Ki67 status. SMs secondary to BC with a fracture are more likely to be PR positive than those with no fracture. Determining the receptor status in SMs may identify high-risk groups for fracture occurrence, and determining the PR status may also guide surgical and hormonal therapy. © 2023 UICC.

Objective: In emergency airway management, the occurrence of surgical tracheotomy complications is increased and may be fatal for the patient. However, the factors that play a role in complication occurrence and lead to lethal outcome are not known. The objective of this study was to determine predictors associated with the occurrence of complications and mortality after emergency surgical tracheostomy. Study Design: Retrospective study with a systematic review of the literature. Setting: Tertiary medical academic center. Subjects and Methods: We included 402 adult patients who underwent emergency surgical tracheostomy under local anesthesia due to upper airway obstruction. Demographic, clinical, complication occurrence, and mortality data were collected. For statistical analysis, univariable and multivariable logistic regression methods were used. Results: In multivariable analysis, significant positive predictors of complication occurrence were previously performed tracheotomy (odds ratio [OR] 3.67, 95% confidence interval [CI], 0.75–17.88), neck pathology (OR 2.05, 95% CI 1.1–1.77), and tracheotomy performed outside the operating room (OR 5.88, 95% CI, 1.58–20). General in-hospital mortality was 4%, but lethal outcome as a direct result of tracheotomy complications occurred in only 4 patients (1%) because of intraoperative and postoperative complications. Conclusion: The existence of neck pathology and situations in which tracheotomy was performed outside the operating room in uncontrolled conditions were significant prognostic factors for complication occurrence. Tracheotomy-related mortality was greater in patients with intraoperative and early postoperative complications. Clinicians should be aware of the increased risk in specific cases, to prepare, prevent, or manage unwanted outcomes in further treatment and care. © American Academy of Otolaryngology–Head and Neck Surgery Foundation 2020.

Objective: To investigate the incidence and identify risk factors for the occurrence of intraoperative hypertension (IOH) during surgery for primary hyperparathyroidism (pHPT). Subjects and Methods: The study included 269 patients surgically treated between January 2008 and January 2012 for pHPT. IOH was defined as an increase in systolic blood pressure ≥20% compared to baseline values which lasted for 15 min. The investigated influence were demographic characteristics, surgical risk score related to physical status (based on the American Society of Anesthesiologists [ASA] classification), comorbidities, type and duration of surgery, and duration of anesthesia on IOH occurrence. The investigated factors were obtained from the patients' medical history, anesthesia charts, and the daily practice database. Logistic regression analysis was done to determine the predictors of IOH. Results: Of the 269 patients, 153 (56.9%) had IOH. Based on the univariate analysis, age, body mass index, ASA status, duration of anesthesia, and preoperative hypertension were risk factors for the occurrence of IOH. Multivariate analysis showed that independent predictors of IOH were a history of hypertension (OR=2.080, 95% CI: 1.102-3.925, p=0.024) and age (OR=0.569, 95% CI: 0.360-0.901, p=0.016). Conclusion: In this study, a high percentage (56%) of the patients developed IOH during surgery for pHPT, which indicates that special attention should be paid to these patients, especially to the high-risk groups: older patients and those with a history of hypertension. Further, this study showed that advanced age and hypertension as a coexisting disease prior to parathyroid surgery were independent risk factors for the occurrence of IOH. © 2017 2017 S.

Introduction: The association between the expression of HIF-1α in the laryngeal carcinoma and the prognosis of disease is quite well documented, but the significance of HIF-1α C1772T polymorphism and its relation to disease phenotype have to be clarified. The aim of this study was to investigate the influence of C1772T polymorphism on the clinical-pathological characteristics and disease-free survival after initial surgical treatment of patients with laryngeal carcinoma. Materials and methods: The prospective cohort study included 65 patients with laryngeal carcinoma. Two representative tumor tissue specimens were taken in each patient during surgery; 1 specimen was used to asses HIF-1α C1772T polymorphism and the other 1 to determine the immunohistochemical expression of HIF-1α, VEGF, as well as CD 34 proteins. The comparison of polymorphism frequency between study and control population was conducted by collecting a 5 mL of peripheral venous blood samples in each subject. Results: Clinicopathological characteristics of laryngeal carcinoma didn’t affect the expression of hypoxia-related biomarkers, such as HIF-1α, VEGF or MVD. The statistically significant association between HIF-1α and VEGF expression was found (P =.034), but not between HIF-1α expression and MVD value (P =.696). The expression of HIF-1α was significantly higher among CT heterozygotes (P =.029). We found a significantly more recurrence among CT heterozygotes compared with patients with CC homozygous alleles (57.10% and 24.30%, respectively; P =.007). Patients with C1772T polymorphic variants had significantly worse disease-free survival compared with patients without polymorphism (Log-rank test, P =.007). Conclusion: HIF-1α C1772T polymorphism was significantly associated with worse disease-free survival which nominates it as a predictor of laryngeal carcinoma relapse. The preoperative assessment of hypoxia-related biomarkers should be used in everyday practice in order to determine the treatment modalities for laryngeal carcinoma. © The Author(s) 2022.
