Evaluation of the preoperative neutrophil-to-lymphocyte ratio as a predictor of the micropapillary component of stage IA lung adenocarcinoma.

OBJECTIVE: To assess the ability of markers of inflammation to identify the solid or micropapillary components of stage IA lung adenocarcinoma and their effects on prognosis. METHODS: We performed a retrospective study of clinicopathologic data from 654 patients with stage IA lung adenocarcinoma collected between 2013 and 2019. Logistic regression analysis was used to identify independent predictors of these components, and we also evaluated the relationship between markers of inflammation and recurrence. RESULTS: Micropapillary-positive participants had high preoperative neutrophil-to-lymphocyte ratios. There were no significant differences in the levels of markers of systemic inflammation between the participants with or without a solid component. Multivariate analysis showed that preoperative neutrophil-to-lymphocyte ratio (odds ratio [OR] = 2.094; 95% confidence interval [CI], 1.668-2.628), tumor size (OR = 1.386; 95% CI, 1.044-1.842), and carcinoembryonic antigen concentration (OR = 1.067; 95% CI, 1.017-1.119) were independent predictors of a micropapillary component. There were no significant correlations between markers of systemic inflammation and the recurrence of stage IA lung adenocarcinoma. CONCLUSIONS: Preoperative neutrophil-to-lymphocyte ratio independently predicts a micropapillary component of stage IA lung adenocarcinoma. Therefore, the potential use of preoperative neutrophil-to-lymphocyte ratio in the optimization of surgical strategies for the treatment of stage IA lung adenocarcinoma should be further studied.

Association between preoperative lactate level and early complications after surgery for isolated extremity fracture.

BACKGROUND: The role of lactate level in selecting the timing of definitive surgery for isolated extremity fracture remains unclear. Therefore, we aimed to elucidate the use of preoperative lactate level for predicting early postoperative complications. METHODS: This was a single-center retrospective observational study of patients with isolated extremity fracture who underwent orthopedic surgery. Patients who underwent lactate level assessment within 24 h prior to surgery were included. The incidence of early postoperative complications was compared between patients with a preoperative lactate level of ≥ 2 and < 2 mmol/L. Moreover, subgroup analyses were performed based on the time from hospital arrival to surgery and fracture type. RESULTS: In total, 187 patients were included in the study. The incidence of postoperative complications was significantly higher in patients with a preoperative lactate level of ≥ 2 mmol/L than those with a preoperative lactate level of < 2 mmol/L. This result did not change after adjusting for age and severity. Further, a high preoperative lactate level was associated with a greater incidence of postoperative complications in patients who underwent definitive surgery within 6 h after arrival. CONCLUSION: A preoperative lactate level of ≥ 2 mmol/L was associated with a greater incidence of early postoperative complications in isolated extremity fractures. Nevertheless, this correlation was only observed among patients who underwent definitive fixation within 6 h after hospital arrival.

Pre-operative body shape concerns moderate excess weight loss trajectory in bariatric surgery patients: a 2-year longitudinal study.

PURPOSE: The main research aim was to inspect whether pre-operative body shape concerns and discomfort as Body Shape Questionnaire (BSQ) scores moderate post-operative weight loss trajectory in bariatric patients. METHODS: Two studies were conducted. Study 1 analyzed cross-sectional data and verified the structural validity of the 34-item BSQ questionnaire on a sample of 327 candidates for bariatric surgery. Study 2 examined longitudinal data, with objective Body Mass Index (BMI) recorded every 6 months, from surgery intervention on, with 5 measurement occasions, from 111 patients who initially completed BSQ as bariatric surgery candidates and then underwent periodic medical post-operative follow-ups, over 2 years. RESULTS: In Study 1, confirmatory factor analysis of a single-dimension model yielded acceptable fit indices and high internal consistency levels. Study 2 showed that post-operative excess BMI reduction trend was not linear and pre-operative BSQ scores moderated it, with a higher risk of weight regain in patients who initially were less concerned with their body shape. CONCLUSIONS: The present findings support the structural validity of the BSQ questionnaire in bariatric candidates and call attention on the role of pre-operative body shape concerns on post-operative weight loss trajectories over 2 years, in accordance with a pathoplasty model. They suggest the need for systematic attention on perceived body image and psychological paths aimed to help bariatric patients regain positive attitudes towards their own body. Level of evidence III, well-designed cohort.

Association between phase angle and clinical outcomes in patients with lumbar spinal stenosis from the preoperative to 12-month postoperative period: A prospective observational study.

No reports of longitudinal studies on phase angle (PhA) in lumbar spinal stenosis (LSS) exist, and its association with postoperative clinical outcomes is unclear. We longitudinally investigated PhA in patients with LSS preoperatively to 12 months postoperatively and determined the association between PhA and the Japanese Orthopedic Association (JOA) score. This prospective observational study included patients who underwent consecutive surgical treatments for clinically and radiologically defined LSS. Outcome measures including walking speed, Timed Up and Go test (TUG), JOA score, and PhA based on bioelectrical impedance analysis were measured preoperatively and at 3, 6, and 12 months postoperatively. Correlations between PhA and the JOA score and motor function were analyzed. The effect of PhA on JOA scores was evaluated using mixed-effect models for repeated measurements (MMRM). Eighty-nine patients were included at baseline, and 85, 85, and 78 patients were analyzed at 3, 6, and 12 months postoperatively, respectively. PhA was 3.9 ± 0.8 (p = 0.086), 4.0 ± 0.8 (p = 0.644), and 4.1 ± 0.9 (p = 0.791) at 3, 6, and 12 months postoperatively and 4.2 ± 0.8 at baseline. PhA was significantly correlated with the JOA score (p < 0.01) and walking speed and TUG results (p < 0.01) at all assessment points. In the MMRM, PhA was associated with the JOA score at all assessment points. Changes in postoperative JOA scores after lumbar spine surgery are associated with PhA at each assessment time point. PhA may be a useful postoperative clinical indicator after surgery for LSS.

Bariatric Surgery and New-Onset Substance Use Disorders: A Systematic review and Meta-analysis.

Increasing evidence suggests that bariatric surgery (BS) patients are at risk for substance abuse disorders (SUD). The purpose of this systematic review and meta-analysis was to determine the relationship between BS and the development of new-onset substance abuse disorder (SUDNO) in bariatric patients. On October 31, 2023, we reviewed the scientific literature following PRISMA guidelines. A total of 3242 studies were analyzed, 7 met the inclusion criteria. The pooled incidence of SUDNO was 4.28%. Patients' characteristics associated with SUDNO included preoperative mental disorders, high pre-BS BMI, and public health insurance. Surgical factors associated with new SUDNOs included severe complications in the peri- or postoperative period. The occurrence of SUDNOs is a non-negligeable complication after BS. Predisposing factors may be identified and preventive actions undertaken.

Discrepancy between clinical and pathological staging of laryngeal carcinoma: a dilemma to be solved.

OBJECTIVES: The aim of this study was to investigate the degree of discrepancy between the clinical and pathological staging of laryngeal carcinoma, and the potential impact of this discrepancy on the outcomes and prognosis. METHODS: This study was conducted on 127 patients who underwent total laryngectomy over five years (October 2016-October 2021). Data collected from pretherapeutic clinical staging regarding the extent of the tumor affection of different laryngeal subsites was compared to the postsurgical pathological assessment. RESULTS: Overall, 12 out of 127 patients (9.4%) in the current study, were clinically over-staged from T3 to T4 due to radiological diagnosis of tumor infiltration of laryngeal cartilages that proved pathologically to be free of tumor. Additionally, discordance in the N stage was found in 12.6% (n = 16). However, stage discrepancy did not have a significant impact on the prognosis and survival. CONCLUSION: Discordance between clinical and pathological TNM staging of laryngeal carcinoma may affect the decision making and the choice of the treatment options. Some improvement can be probably achieved with advancements and higher accuracy of the preoperative diagnostic tools.

Impact of preoperative infection on the outcomes of liver transplant recipients: a national propensity score-matched retrospective cohort study in China.

BACKGROUND: Impact of preoperative infection on liver transplantation (LT) needs further investigation. MATERIALS AND METHODS: From 1 January 2015 to 31 December 2022, 24 122 eligible patients receiving LT were enrolled from the China Liver Transplant Registry database. The outcomes of LT were compared after using the propensity score-matched analysis. RESULTS: Compared to the noninfection group, patients in the infection group were more likely to have postoperative effusion, infection, abdominal bleeding, and biliary complications (all P <0.01), and they had shorter 30-day, 90-day survival, and overall survival (all P <0.01). Cox proportional hazards regression analysis revealed that MELD score and cold ischemia time were risk factors for the overall survival in the infection group (both P <0.05). Besides, compared to the nonpulmonary group, patients in the pulmonary group were more likely to have postoperative effusion and infection (both P <0.0001), and less likely to have postoperative abscess and early allograft dysfunction (both P <0.05). Patients in the nonabdominal group also had a higher proportion of postoperative infection than those in the abdominal group ( P <0.05). Furthermore, compared to the number=1 group, patients in the number ≥2 group were more prone to postoperative effusion and infection (both P <0.01), and they also had shorter 30-day and 90-day survival (both P <0.05). CONCLUSION: Preoperative infection can result in a higher incidence of early postoperative complications and shorter survival in liver transplant recipients. The types and number of infection sites will also influence the prognosis of liver transplant recipients.

The Influence of the Preoperative Albumin to Alkaline Phosphatase Ratio on Overall Survival in Post-Radical Surgery for Colorectal Cancer and the Construction of a Nomogram Prediction Model.

PURPOSE: The albumin to alkaline phosphatase ratio (AAPR) is a newly developed blood biomarker that has been reported to have prognostic value in several types of cancers. The aim of this study was to investigate the predictive value of AAPR in overall survival after radical colon cancer surgery in patients with stage I-III colorectal cancer (CRC). METHODS: The clinical data of 221 eligible patients with stage I ∼ III CRC were retrospectively analyzed. A series of survival analyses were performed to assess the prognostic value of AAPR. Univariate and multifactorial Cox analyses were performed to identify independent risk factors. Columnar graph prediction models were further constructed based on independent risk factors such as AAPR, and their predictive properties were validated. RESULTS: The optimal cutoff value of preoperative AAPR for postoperative overall survival (OS) in patients undergoing laparoscopic radical CRC was .495 as shown by univariate and multifactorial Cox regression analysis. The factors of age ≤65 years, Tumor-Node-Metastasis (TNM) stage I-II, tumor grading (high/medium differentiation), CEA ≤5, and AAPR ≥.495 were associated with better OS (P < .05). CONCLUSIONS: Preoperative AAPR level was a good predictor of postoperative survival in patients undergoing laparoscopic radical CRC surgery, and AAPR <.495 was an independent risk factor for decreased postoperative OS.

The effect of guided imagery applied on geriatric orthopaedic patients on preoperative anxiety and comfort.

BACKGROUND: This study was designed to examine the effect of guided imagery applied to geriatric orthopaedic patients on preoperative anxiety and comfort. METHODS: This study was conducted as a randomized controlled trial. The population of the study consisted of geriatric patients treated in the orthopaedics and traumatology clinic of a university hospital. The sample consisted of 80 patients, including the experimental group (n = 40) and the control group (n = 40). Personal Descriptive Form, The State-Trait Anxiety Inventory (STAI) and General Comfort Scale were used as data collection tools. RESULTS: After the guided imagery application, it was determined that the anxiety of the experimental group decreased statistically significantly, and their comfort improved (P < 0.05). CONCLUSION: After the imagery, it was determined that the patients in the experimental group had a decrease in their anxiety level and an improvement in their comfort. Since it is a low-cost and easily accessible method, applying imagery in the preoperative period is recommended.

Commentary on "Brain Injury During Transition in the Newborn With Congenital Heart Disease: Hazards of the Preoperative Period".

BRAIN INJURY DURING TRANSITION IN THE NEWBORN WITH CONGENITAL HEART DISEASE: HAZARDS OF THE PREOPERATIVE PERIOD: Jennifer M. Lynch, J. William Gaynor, Daniel J. Licht Seminars in Pediatric Neurology Volume 28, December 2018, Pages 60-65 Infants born with critical congenital heart disease are at risk for neurodevelopmental morbidities later in life. In-utero differences in fetal circulation lead to vulnerabilities which lead to an increased incidence of stroke, white matter injury, and brain immaturity. Recent work has shown these infants may be most vulnerable to brain injury during the early neonatal period when they are awaiting their cardiac surgeries. Novel imaging and monitoring modalities are being employed to investigate this crucial time period and elucidate the precise timing and cause of brain injury in this population.

Correlation between preoperative frailty and postoperative delirium in elderly patients undergoing hip arthroplasty.

BACKGROUND: Postoperative delirium (POD) refers to acute brain dysfunction occurring within 7 days after operation or before discharge. Frailty refers to the state that the body's physiological reserve is insufficient, so that the compensative capacity to endogenous and exogenous stress stimuli decreases. The purpose of this study is to explore the association of preoperative frailty (PF) with POD in elderly patients undergoing hip arthroplasty. METHODS: Totally 228 elderly patients (age ≥ 65 years) who received elective hip arthroplasty in the Ningbo No. 6 Hospital between December 2021 and June 2022 were enrolled. One day before surgery, the frailty phenotype scale was adopted for evaluation of patients' frailty. On the 1st-3rd day after operation, the confusion assessment method was adopted for evaluation of delirium, and the patients were grouped into a POD group and non-POD group. Logistic regression was conducted to analyze the correlation between PF and POD. RESULTS: Among the patients, the incidence of PF was 30.70% (70/228), and the incidence of delirium within 3 days after operation was 25.88% (59/228). According to binary logistic regression analysis, PF, age, hypertension, diabetes mellitus, and preoperative sleep disorder were independent risk factors for POD in elderly patients undergoing hip arthroplasty (all P < .05). CONCLUSION: PF is a crucial risk factor for POD in elderly patients undergoing hip arthroplasty.

The Prognostic Impact of Preoperative Osteopenia in Patients With Colorectal Cancer.

BACKGROUND: Osteopenia, a condition in which bone mineral density is lower than normal, is a noted risk factor that leads to a shortened healthy life expectancy. OBJECTIVE: To investigate the prognostic impact of preoperative osteopenia in patients with colorectal cancer. DESIGN: This was a retrospective study. SETTING: This study was conducted at a university hospital. PATIENTS: A total of 1086 patients with stage I to III colorectal cancer who underwent curative resection. MAIN OUTCOME MEASURES: Osteopenia was evaluated with CT. Overall survival, disease-specific survival, and recurrence-free survival were the primary end points. RESULTS: Osteopenia was identified in 300 patients (27.6%). Compared with the no osteopenia group, the 5-year overall survival (74.0% vs 93.4%, p < 0.001), disease-specific survival (81.6% vs 97.2%, p < 0.001), and recurrence-free survival rates (57.1% vs 88.3%, p < 0.001) were significantly lower in the osteopenia group. Multivariate analyses showed that preoperative osteopenia was significantly associated with worse overall survival (HR: 4.135; 95% CI, 2.963-5.770; p < 0.001), disease-specific survival (HR: 7.673; 95% CI, 4.646-12.675; p < 0.001), and recurrence-free survival (HR: 5.039; 95% CI, 3.811-6.662; p < 0.001). The prognosis of the osteopenia group was poorer than that of the no osteopenia group in every stage: 5-year overall survival (stage I: 89.4% vs 96.9%, p = 0.028; stage II: 76.5% vs 91.9%, p < 0.001; stage III: 56.4% vs 90.8%, p < 0.001) and 5-year recurrence-free survival (stage I: 85.4% vs 96.6%, p = 0.002; stage II: 62.0% vs 86.5%, p < 0.001; stage III: 26.4% vs 80.0%, p < 0.001). LIMITATIONS: The main limitations are retrospective single-institutional features and races of the study population. CONCLUSIONS: Preoperative osteopenia could be a strong predictive marker for long-term prognosis in colorectal cancer regardless of stage. EL IMPACTO PRONSTICO DE LA OSTEOPENIA PREOPERATORIA EN PACIENTES CON CNCER COLORRECTAL: ANTECEDENTES:La osteopenia, una afección en la que la densidad mineral ósea es más baja de lo normal, es un relevante factor de riesgo que conduce a una expectativa menor de vida saludable.OBJETIVO:Investigar el impacto pronóstico de la osteopenia preoperatoria en pacientes con cáncer colorrectal (CCR).DISEÑO:Un estudio retrospectivo.AJUSTE:Estudio realizado en un hospital universitario.PACIENTES:Un total de 1.086 pacientes con CCR en estadio I-III sometidos a una resección curativa.PRINCIPALES MEDIDAS DE RESULTADO:La osteopenia se evaluó con imágenes de tomografía computarizada. La supervivencia global la supervivencia específica de la enfermedad y la supervivencia libre de recurrencia fueron los criterios de valoración primaria.RESULTADOS:Se identificó osteopenia en 300 pacientes (27,6%). En comparación con el grupo sin osteopenia, las tasas de supervivencia global a 5 años (74,0% frente a 93,4%, p < 0,001), supervivencia especifica de la enfermedad (81,6 % frente a 97,2%, p < 0,001) tasas de supervivencia libre de recurrencia (57,1% frente a 88,3%, p < 0,001) fueron significativamente más bajas en el grupo de osteopenia. Los análisis multivariados mostraron que la osteopenia preoperatoria se asoció significativamente con una peor supervivencia global (HR 4,135; IC 95% 2,963-5,770; p < 0,001), supervivencia especifica de la enfermedad (HR 7,673; IC 95% 4,646-12,675; p < 0,001) y tasas de supervivencia libre de recurrencia (HR 5,039; IC 95% 3,811-6,662; p < 0,001). El pronóstico del grupo con osteopenia fue peor que el del grupo sin osteopenia en todos los estadios: supervivencia global a 5 años (estadio I: 89,4% frente a 96,9%, p = 0,028; estadio II: 76,5% frente a 91,9%, p < 0,001; estadio III: 56,4% frente a 90,8%, p < 0,001) y tasas de supervivencia libre de recurrencia a 5 años (estadio I: 85,4% frente a 96,6%, p < 0,002; estadio II: 62,0% frente a 86,5%, p < 0,001; estadio III: 26,4% frente a 80,0%, p < 0,001).LIMITACIONES:Las principales limitaciones son las características retrospectivas de una sola institución y las razas de la población de estudio.CONCLUSIONES:La osteopenia preoperatoria puede ser un fuerte marcador predictivo para el pronóstico a largo plazo en CCR independientemente de la etapa.

Preoperative Treatment of Locally Advanced Rectal Cancer.

BACKGROUND: Pelvic radiation plus sensitizing chemotherapy with a fluoropyrimidine (chemoradiotherapy) before surgery is standard care for locally advanced rectal cancer in North America. Whether neoadjuvant chemotherapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) can be used in lieu of chemoradiotherapy is uncertain. METHODS: We conducted a multicenter, unblinded, noninferiority, randomized trial of neoadjuvant FOLFOX (with chemoradiotherapy given only if the primary tumor decreased in size by <20% or if FOLFOX was discontinued because of side effects) as compared with chemoradiotherapy. Adults with rectal cancer that had been clinically staged as T2 node-positive, T3 node-negative, or T3 node-positive who were candidates for sphincter-sparing surgery were eligible to participate. The primary end point was disease-free survival. Noninferiority would be claimed if the upper limit of the two-sided 90.2% confidence interval of the hazard ratio for disease recurrence or death did not exceed 1.29. Secondary end points included overall survival, local recurrence (in a time-to-event analysis), complete pathological resection, complete response, and toxic effects. RESULTS: From June 2012 through December 2018, a total of 1194 patients underwent randomization and 1128 started treatment; among those who started treatment, 585 were in the FOLFOX group and 543 in the chemoradiotherapy group. At a median follow-up of 58 months, FOLFOX was noninferior to chemoradiotherapy for disease-free survival (hazard ratio for disease recurrence or death, 0.92; 90.2% confidence interval [CI], 0.74 to 1.14; P = 0.005 for noninferiority). Five-year disease-free survival was 80.8% (95% CI, 77.9 to 83.7) in the FOLFOX group and 78.6% (95% CI, 75.4 to 81.8) in the chemoradiotherapy group. The groups were similar with respect to overall survival (hazard ratio for death, 1.04; 95% CI, 0.74 to 1.44) and local recurrence (hazard ratio, 1.18; 95% CI, 0.44 to 3.16). In the FOLFOX group, 53 patients (9.1%) received preoperative chemoradiotherapy and 8 (1.4%) received postoperative chemoradiotherapy. CONCLUSIONS: In patients with locally advanced rectal cancer who were eligible for sphincter-sparing surgery, preoperative FOLFOX was noninferior to preoperative chemoradiotherapy with respect to disease-free survival.

Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales.

Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Prevalence of preoperative opioid usage and its impact on postoperative outcomes: a retrospective cohort study.

PURPOSE: Preoperative opioid treatment increases postoperative adverse events. This study was aimed to analyze preoperative opioid prevalence in countries with low opioid consumption. Additionally, the effect of low opioid usage on postoperative outcomes was also investigated. METHODS: We conducted this single center retrospective cohort analysis in a Japanese university-affiliated hospital to investigate opioid usage and its impact on the duration of postoperative hospitalization and in-hospital mortality. Adult patients who underwent general anesthesia between 2015 and 2020 were included. We extracted the patients' characteristics, surgical information and postoperative outcomes. Subgroup analysis to address opioid dose effect was performed in high and low dose opioid subgroups. RESULTS: Among 20,306 inpatients, 535 (2.63%) patients used opioids preoperatively. Tramadol was the most frequently used opioid. The median morphine equivalent (MME) dose was 15 mg/day. Median duration of hospitalization was 18 and 9 days in the opioid and non-opioid groups, and in-hospital mortality was 2.06% and 0.42%. Multivariable regression analysis demonstrated that preoperative opioid use was associated with a longer duration of hospitalization and in-hospital mortality. Subgroup analysis demonstrated longer durations of hospitalization in both high (> 30 mg/day MME) and low (≤ 30 mg/day MME) dose opioid groups, while higher in-hospital mortality was seen only in the high dose opioid group. CONCLUSIONS: Preoperative opioid usage was one-tenth of the United States average. Despite its low prevalence and small dosage, preoperative opioid usage was associated with poor postoperative outcomes. Dedicated perioperative interventions to prevent opioid-associated adverse events should be developed even in countries with low opioid consumption.

Prognostic value of pre-therapeutic FDG-PET radiomic analysis in gastro-esophageal junction cancer.

The main aim of this study was to evaluate the prognostic value of radiomic approach in pre-therapeutic 18F-fluorodeoxyglucose positron-emission tomography (FDG-PET/CT) in a large cohort of patients with gastro-esophageal junction cancer (GEJC). This was a retrospective monocenter study including 97 consecutive patients with GEJC who underwent a pre-therapeutic FDG-PET and were followed up for 3 years. Standard first-order radiomic PET indices including SUVmax, SUVmean, SUVpeak, MTV and TLG and 32 textural features (TFs) were calculated using LIFEx software on PET imaging. Prognostic significance of these parameters was assessed in univariate and multivariate analysis. Relapse-free survival (RFS) and overall survival (OS) were respectively chosen as primary and secondary endpoints. An internal validation cohort was used by randomly drawing one-third of included patients. The main characteristics of this cohort were: median age of 65 years [41-88], sex ratio H/F = 83/14, 81.5% of patients with a histopathology of adenocarcinoma and 43.3% with a stage IV disease. The median follow-up was 28.5 months [4.2-108.5]. Seventy-seven (79.4%) patients had locoregional or distant progression or recurrence and 71 (73.2%) died. In univariate analysis, SUVmean, Histogram-Entropy and 2 TFs (GLCM-Homogeneity and GLCM-Energy) were significantly correlated with RFS and OS, as well as 2 others TFs (GLRLM-LRE and GLRLM-GLNU) with OS only. In multivariate analysis, Histogram-Entropy remained an independent prognostic factor of both RFS and OS whereas SUVmean was an independent prognostic factor of OS only. These results were partially confirmed in our internal validation cohort of 33 patients. Our results suggest that radiomic approach reveals independent prognostic factors for survival in patients with GEJC.

Impact of fluoroquinolone administration and gut mucosal colonization on the risk of pre-engraftment bloodstream infections after allogeneic hematopoietic cell transplantation.

Fluoroquinolones (FQ) has been used after allogeneic hematopoietic stem cell transplantation (allo-HCT) for decades. This study on 284 allo-HCT recipients aimed to analyze the impact of FQ on pre-engraftment BSI. A total of 154 patients were colonized with resistant gram-negative bacteria, and 130 patients were not. Colonized patients did not receive FQ (n = 147) except 7 who received FQ as sequential therapy; 98 non-colonized patients received FQ, whereas 32 did not. Gram-negative (p < 0.0001), and ESBL-E BSI (p < 0.0001) were higher in colonized patients receiving FQ. No difference was found in gram-positive BSI (p = 0.452). In multivariate analysis colonized patients with (p < 0.0001) or without FQ (p = 0.007), omission of FQ in non-colonized patients (p = 0.038), and active disease (p = 0.042) were associated with gram-negative BSI, whereas mismatched unrelated donor transplantations - with gram-positive BSI (p = 0.009). Colonized patients with FQ have a higher risk of gram-negative BSI. In non-colonized patients, FQ prophylaxis is effective approach significantly reducing gram-negative BSI risk.

A Comparison Between Preoperative and Intraoperative Measurement and Classification of the Size of Rotator Cuff Tears / Uma comparação entre a medição e a classificação da ruptura do manguito rotador no pré-operatório e no intraoperatório

Abstract Purpose To evaluate the agreement in tear size obtained through preoperative imaging and intraoperative measurement, and to determine the accuracy of preoper-ative imaging in the classification of tear size and identification of tears in each rotator cuff tendon. Methods Data from 44 patients recruited to a randomized controlled trial were reviewed retrospectively. Size and location of the rotator cuff tears were confirmed by either ultrasound or magnetic resonance imaging scans preoperatively and evaluated during surgery. A t-test and Bland and Altman plot were used to determine the agreement between the preoperative and intraoperative measurements. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for tear size and involvement of the rotator cuff tendon. Results There was good agreement in terms of the measurements (91%) and classification (89%) of the tear size preoperatively and during surgery. When classifying tear size, the sensitivity and PPV were high for medium-sized tears (100%) and lower for large tears (75%), reflecting that all medium-sized tears but not all large tears were identified preoperatively. For the preoperative identification of the tears, the sensitivity and PPV were highest for the supraspinatus (84%), with progressively lower sensitivities and PPV for the infraspinatus (57%), subscapularis (17%) and teres minor (0%). Conclusions Through preoperative imaging, the measurement or classification of the tear size can be accurately performed. Where there is disagreement, it is unclear whether the tear size is either underestimated on the scan or overestimated during surgery. The high sensitivity demonstrates that a supraspinatus tear is usually detected by scan. The lower sensitivities for the infraspinatus and subscapularis indicate that the identification of tears in these tendons is less accurate.

Resumo Objetivo Avaliar a concordância no tamanho de ruptura obtido por imagem préoperatória e por medição intraoperatória, e determinar a precisão da imagem préoperatória na classificação do tamanho da ruptura e na identificação de rupturas em cada tendão do manguito rotador. Métodos Os dados de 44 pacientes recrutados para um ensaio controlado randomizado foram revisados retrospectivamente. O tamanho e a localização do manguito rotador foram confirmados por ultrassom ou ressonância magnética préoperatórios, e avaliados durante a cirurgia. Um teste t e o gráfico de Bland e Altman foram usados para determinar a concordância entre as medições pré-operatória e intraoperatória. Sensibilidade, especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) foram calculados para o tamanho do rompimento e o envolvimento do tendão do manguito rotador. Resultados Houve boa concordância para medidas de tamanho da ruptura (91%) e classificação (89%) pré-operatória e durante a cirurgia. Ao classificar o tamanho da ruptura, a sensibilidade e o VPP foram elevados para rupturas de tamanho médio (100%), e menor para rupturas grandes (75%), o que indica que todas as rupturas de tamanho médio, mas nem todas as grandes, foram identificadas pré-operatoriamente. Para a identificação de rupturas, a sensibilidade pré-operatória e o VPP foram maiores para o supraespinal (84%), com sensibilidade e VPP progressivamente menores para o infraespinal (57%), o subescapular (17%), e o redondo menor (0%). Conclusões Por meio da imagem pré-operatória, pode-se medir ou classificar com precisão o tamanho da ruptura. Quando há discordância, não está claro se o tamanho da ruptura é subestimado no exame ou superestimado durante a cirurgia. A alta sensibilidade demonstra que uma ruptura do supraespinal é geralmente detectada por escaneamento. As sensibilidades mais baixas para o infraespinal e o subescapular indicam que a identificação de rupturas nestes tendões é menos precisa.
