Transanal total mesorectal excision: short- and long-term results of four certified colorectal cancer centers in Germany.

BACKGROUND: Transanal total mesorectal excision (TaTME), a novel approach for treating low rectal cancer, holds promise. However, concerns exist in certain countries about their oncologic safety due to less-than-optimal outcomes on global studies. This research seeks to evaluate the long-term oncologic outcomes focusing on local recurrence rate and overall survival after TaTME surgery in Germany. PATIENTS AND METHODS: This study analyzed data from patients who underwent elective TaTME surgery between 2014 and 2021 in four certified colorectal cancer centers in Germany. Primary endpoints were 3-year local recurrence rate and local recurrence-free survival (LRFS). Secondary outcomes encompassed overall survival (OS), operative time, completeness of local tumor resection, lymph node resection, and postoperative complications. RESULTS: A total of 378 patients were analyzed (mean age 61.6 years; 272 males, 72%). After a median follow-up period of 2.5 years, 326 patients with UICC-stages I-III and tumor operability included in survival analyses. Local recurrence was observed in 8 individuals, leading to a 3-year cumulative local recurrence rate of 2.2% and a 3-year LRFS rate of 88.1%. The 3-year OS rate stood at 88.9%. Within 30 days after surgery, anastomotic leakage occurred in 19 cases (5%), whereas a presacral abscess was present in 12 patients (3.2%). CONCLUSION: TaTME proves effective in addressing the anatomical and technical challenges of low rectal surgery and is associated with pleasing short- and long-term results. However, its safe integration into surgical routine necessitates sufficient knowledge and a previously completed training program.

Prognostic Value of the Advanced Lung Cancer Inflammation Index Ratio in Patients with Acute Myocardial Infarction Complicated by Cardiogenic Shock: A Cohort Study.

Background: Acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) carries a high mortality risk. Inflammation and nutrition are involved in the pathogenesis and prognosis of both AMI and CS. The advanced lung cancer inflammation index ratio (ALI) combines the inflammatory and nutritional status. Our present study aimed to explore the prognostic value of ALI in patients with CS following AMI. Methods: In total, 217 consecutive patients with AMI complicated by CS were divided into two groups based on the ALI admissions cut-off: ≤ 12.69 and > 12.69. The primary endpoint of this study was 30-day all-cause mortality. The secondary endpoints were gastrointestinal hemorrhage and major adverse cardiovascular events (MACEs), including 30-day all-cause mortality, atrioventricular block, ventricular tachycardia/ventricular fibrillation, and nonfatal stroke. The association of ALI with the study endpoints was analyzed by Cox regression analysis. Results: During the 30-day follow-up period after admission, 104 (47.9%) patients died and 150 (69.1%) suffered MACEs. The Kaplan-Meier analysis revealed significantly higher cumulative mortality and lower MACE rates in the low-ALI group compared to the high-ALI group (both log-rank p < 0.001). The 30-day mortality rate was significantly higher in patients with ALI ≤ 12.69 compared to ALI > 12.69 (72.1% vs. 22.6%; p < 0.001). Furthermore, the incidence of MACEs was higher in patients with ALI ≤ 12.69 (85.6% vs. 51.9%; p < 0.001). The receiver operating curve showed that ALI had a modest predictive value (area under the curve [AUC]: 0.789, 95% confidence interval [CI]: 0.729, 0.850). After multivariable adjustment, ALI ≤ 12.69 was an independent predictor for both 30-day all-cause mortality (hazard ratio [HR]: 3.327; 95% CI: 2.053, 5.389; p < 0.001) and 30-day MACEs (HR: 2.250; 95% CI 1.553, 3.260; p < 0.001). Furthermore, the addition of ALI to a base model containing clinical and laboratory data statistically improved the predictive value. Conclusions: Assessing ALI levels upon admission can provide important information for the short-term prognostic assessment of patients with AMI complicated by CS. A lower ALI may serve as an independent predictor of increased 30-day all-cause mortality and MACEs.

Is operation time over the benchmark value a risk factor for worse short-term outcomes after laparoscopic liver resection?

Introduction: Laparoscopic liver resection is a challenging surgical procedure that may require prolonged operation time, particularly during the learning curve. Operation time significantly decreases with increasing experience; however, prolonged operation time may significantly increase the risk of postoperative complications. Aim: To assess whether prolonged operation time over the benchmark value influences short-term postoperative outcomes after laparoscopic liver resection. Material and methods: A retrospective cohort study based on data from the National Polish Registry of Minimally Invasive Liver Surgery was performed. A total of 197 cases consisting of left lateral sectionectomy (LLS), left hemihepatectomy (LH), and right hemihepatectomy (RH) with established benchmark values for operation time were included. Data about potential confounders for prolonged operation time and worse short-term outcomes were exported. Results: Most cases (129; 65.5%) were performed during the learning curve, while the largest rate was observed in LLS (57; 78.1%). Median operation time exceeded the benchmark value in LLS (Me = 210 min) and LH (Me = 350 min), while in RH the benchmark value was exceeded in 39 (44.3%) cases. Textbook outcomes were achieved in 138 (70.1%) cases. Univariate analysis (OR = 1.11; 95% CI: 0.61-2.06; p = 0.720) and multivariate analysis (OR = 1.16; 95% CI: 0.50-2.68; p = 0.734) did not reveal a significant impact of prolonged surgery on failing to achieve a textbook outcome. Conclusions: Prolonging the time of laparoscopic liver resection does not significantly impair postoperative results. There is no reason related to the patients' safety to avoid prolonging the time of laparoscopic liver resection over the benchmark value.

Predictors of short-term mortality in cardiogenic shock: insights from an Egyptian multicenter registry.

BACKGROUND: Cardiogenic shock (CS) remains a major cause of morbidity and mortality, particularly in developing countries where there are limited resources and a lack of data on CS outcomes. This study aimed to investigate 30-day all-cause mortality in Egyptian patients with CS at tertiary referral centers. RESULTS: This prospective, observational multicenter registry analyzed 16,681 patients from six cardiac centers, to evaluate the incidence, causes and predictors of CS-related mortality. Among the 529 diagnosed CS patients, 68.2% had an ischemic etiology. No discernable variations were observed in clinical or laboratory features, as well as mortality rates, between ischemic and non-ischemic CS patients. Within 30 days, 210 deaths (39.7%) occurred. Non-survivors with ischemic CS had a higher prevalence of diabetes, worsening renal function, and were more likely to receive multiple inotropes. Mortality did not significantly differ between acute coronary syndrome patients with ST elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) (42.7% vs. 43.7%, p < 0.887). However, anterior STEMI patients had significantly higher mortality than those with inferior STEMI (49.5% vs. 21.6%, p < 0.003). Multivariate regression analysis identified predictors of mortality in CS, including the median hospital stay duration, leucocyte count, alanine transaminase levels, highest creatinine levels, resuscitated cardiac arrest, and use of norepinephrine, epinephrine, and dopamine. CONCLUSION: In an Egyptian cohort, CS incidence was 3.17%, with no mortality difference based on the underlying etiology. Independent predictors of 30-day all-cause mortality included worsening renal function, leucocyte count, resuscitated cardiac arrest, and use of multiple inotropes/vasopressors.

Cluster analysis of clinical, angiographic, and laboratory parameters in patients with ST-segment elevation myocardial infarction.

INTRODUCTION: ST-segment elevation myocardial infarction (STEMI) represents the most harmful clinical manifestation of coronary artery disease. Risk assessment plays a beneficial role in determining both the treatment approach and the appropriate time for discharge. Hierarchical agglomerative clustering (HAC), a machine learning algorithm, is an innovative approach employed for the categorization of patients with comparable clinical and laboratory features. The aim of the present study was to investigate the role of HAC in categorizing STEMI patients and to compare the results of these patients. METHODS: A total of 3205 patients who were diagnosed with STEMI at the university hospital emergency clinic between 2015 and 2023 were included in the study. The patients were divided into 2 different phenotypic disease clusters using the HAC method, and their outcomes were compared. RESULTS: In the present study, a total of 3205 STEMI patients were included; 2731 patients were in cluster 1, and 474 patients were in cluster 2. Mortality was observed in 147 (5.4%) patients in cluster 1 and 108 (23%) patients in cluster 2 (chi-square P value < 0.01). Survival analysis revealed that patients in cluster 2 had a significantly greater risk of death than patients in cluster 1 did (log-rank P < 0.001). After adjustment for age and sex in the Cox proportional hazards model, cluster 2 exhibited a notably greater risk of death than did cluster 1 (HR = 3.51, 95% CI = 2.71-4.54; P < 0.001). CONCLUSION: Our study showed that the HAC method may be a potential tool for predicting one-month mortality in STEMI patients.

Neurosurgical short-term outcomes for pediatric medulloblastoma patients and molecular correlations: a 10-year single-center observation cohort study.

This study examined the risk factors for short-term outcomes, focusing particularly on the associations among molecular subgroups. The analysis focused on the data of pediatric patients with medulloblastoma between 2013 and 2023, as well as operative complications, length of stay from surgery to adjuvant treatment, 30-day unplanned reoperation, unplanned readmission, and mortality. 148 patients were included. Patients with the SHH TP53-wildtype exhibited a lower incidence of complications (45.2% vs. 66.0%, odds ratio [OR] 0.358, 95% confidence interval [CI] 0.160 - 0.802). Female sex (0.437, 0.207 - 0.919) was identified as an independent protective factor for complications, and brainstem involvement (1.900, 1.297 - 2.784) was identified as a risk factor. Surgical time was associated with an increased risk of complications (1.004, 1.001 - 1.008), duration of hospitalization (1.006, 1.003 - 1.010), and reoperation (1.003, 1.001 - 1.006). Age was found to be a predictor of improved outcomes, as each additional year was associated with a 14.1% decrease in the likelihood of experiencing a prolonged length of stay (0.859, 0.772 - 0.956). Patients without metastasis exhibited a reduced risk of reoperation (0.322, 0.133 - 0.784) and readmission (0.208, 0.074 - 0.581). There is a significant degree of variability in the occurrence of operative complications in pediatric patients with medulloblastoma. SHH TP53-wildtype medulloblastoma is commonly correlated with a decreased incidence of complications. The short-term outcomes of patients are influenced by various unmodifiable endogenous factors. These findings could enhance the knowledge of onconeurosurgeons and alleviate the challenges associated with patient/parent education through personalized risk communication. However, the importance of a dedicated center with expertise surgical team and experienced neurosurgeon in improving neurosurgical outcomes appears self-evident.

Laparoscopic ileocecal-sparing vs traditional right hemicolectomy for cancer of the hepatic flexure or proximal transverse colon: a dual-center propensity score-matched study.

Background: Traditional right hemicolectomy (TRH) is the standard treatment for patients with nonmetastatic right colon cancer. However, the ileocecum, a vital organ with mechanical and immune functions, is removed in these patients regardless of the tumor location. This study aimed to evaluate the technical and oncological safety of laparoscopic ileocecal-sparing right hemicolectomy (LISH). Method: Patients who underwent LISH at two tertiary medical centers were matched 1:2 with patients who underwent TRH by propensity score matching based on sex, age, body mass index, tumor location, and disease stage. Data on surgical and perioperative outcomes were collected. Oncological safety was evaluated in a specimen-oriented manner. Lymph nodes (LNs) near the ileocolic artery (ICA) were examined independently in the LISH group. Disease outcomes were recorded for patients who completed one year of follow-up. Results: In all, 34 patients in the LISH group and 68 patients in the TRH group were matched. LISH added 8 minutes to the dissection of LNs around the ileocolic vessels (groups 201/201d, 202, and 203 LNs), without affecting the total operation time, blood loss, or perioperative adverse event rate. Compared with TRH, LISH had a comparable lymphadenectomy quality, specimen quality, and safety margin while preserving a more functional bowel. The LISH group had no cases of LN metastasis near the ICA. No difference was detected in the recurrence rate at the 1-year follow-up time point between the two groups. Conclusion: In this dual-center study, LISH presented comparable surgical and oncological safety for patients with hepatic flexure or proximal transverse colon cancer.

Association of AST/ALT ratio with 90-day outcomes in patients with acute exacerbation of chronic liver disease: a prospective multicenter cohort study in China.

Background and aim: A high aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio is associated with liver injury in liver disease; however, no data exist regarding its relationship with 90-day prognosis in patients with acute exacerbation of chronic liver disease. Methods: In this study, 3,758 participants (955 with advanced fibrosis and 2,803 with cirrhosis) from the CATCH-LIFE cohort in China were included. The relationships between different AST/ALT ratios and the risk of adverse 90-day outcomes (death or liver transplantation) were determined in patients with cirrhosis or hepatitis B virus (HBV)-associated advanced fibrosis, respectively. Results: In the patients with HBV-associated advanced fibrosis, the risk of 90-day adverse outcomes increased with AST/ALT ratio; after adjusting for all confounding factors, the risk of adverse 90-day outcomes was the highest when AST/ALT ratio was more than 1.08 (OR = 6.91 [95% CI = 1.789-26.721], p = 0.005), and the AST/ALT ratio of >1.9 accelerated the development of adverse outcomes. In patients with cirrhosis, an AST/ALT ratio > 1.38 increased the risk of adverse 90-day outcomes in all univariables (OR = 1.551 [95% CI = 1.216-1.983], p < 0.001) and multivariable-adjusted analyses (OR = 1.847 [95% CI = 1.361-2.514], p < 0.001), and an elevated AST/ALT ratio (<2.65) accelerated the incidence of 90-day adverse outcomes. An AST/ALT ratio of >1.38 corresponded with a more than 20% incidence of adverse outcomes in patients with cirrhosis. Conclusion: The AST/ALT ratio is an independent risk factor for adverse 90-day outcomes in patients with cirrhosis and HBV-associated advanced fibrosis. The cutoff values of the AST/ALT ratio could help clinicians monitor the condition of patients when making clinical decisions.

Robotic-assisted total knee arthroplasty is not associated with improved accuracy in implant position and alignment compared to conventional instrumentation in the execution of a preoperative digital plan.

Purpose: The primary objective of the present study was to evaluate if robotic-assisted total knee arthroplasty (RO-TKA) results in improved accuracy compared to conventional TKA (CO-TKA) with respect to alignment and component positioning executing a preoperative digital plan. The secondary objective was to compare patient-reported outcome measures (PROMs) between the two groups at 6 months of follow-up (FU). Methods: Patients who underwent primary TKA using the concept of constitutional alignment were identified from the database. Each patient underwent preoperative digital planning as well as postoperative evaluation of the preoperative plan (alignment and component position) using mediCAD® software (Hectec GmbH). Two groups were formed: (i) The RO-TKA group (n = 30) consisted of patients who underwent TKA with a robotic surgical system (ROSA®, Zimmer Biomet) and (ii) the CO-TKA group (n = 67) consisted of patients who underwent TKA with conventional instrumentation. To assess accuracy, all qualitative variables were analysed using the χ 2 test. Tegner activity scale, Oxford Knee Score and visual analogue scale were assessed preop and at 6-month FU. To assess differences between the two groups, a 2 × 2 repeated measures analysis of variance was performed. Results: There was no significant (p > 0.05) difference in the accuracy of alignment as well as tibial and femoral component position between the two groups. At the 6-month FU, there was no significant (p > 0.05) difference in PROMs between the two groups. Conclusion: While robotic TKA may have some potential advantages, no significant difference was found between robotic and conventional TKA with respect to limb alignment, clinical outcomes and component positioning. Level of Evidence: Level III.

RESULTS: This article presents the clinical presentation of the newborns included, the analysis of factors associated with short-term outcome at hospital discharge and the organizational factors associated with treatment with therapeutic hypothermia. CONCLUSION: These data illustrate the value of a prospective cohort to analyze the management of anoxo-ischemic encephalopathy in France.

Short-term outcomes and long-term quality of life of reconstruction methods after proximal gastrectomy: a systematic review and meta-analysis.

BACKGROUND: The optimal reconstruction method after proximal gastrectomy remains unclear. This systematic review and meta-analysis aimed to compare the short-term outcomes and long-term quality of life of various reconstruction methods. METHODS: PubMed, Embase, Web of Science and Cochrane Library were searched to identify comparative studies concerning the reconstruction methods after proximal gastrectomy. The reconstruction methods were classified into six groups: double tract reconstruction (DTR), esophagogastrostomy (EG), gastric tube reconstruction (GT), jejunal interposition (JI), jejunal pouch interposition (JPI) and double flap technique (DFT). Esophagogastric anastomosis group (EG group) included EG, GT and DFT, while esophagojejunal anastomosis group (EJ group) included DTR, JI and JPI. RESULTS: A total of 27 studies with 2410 patients were included in this meta-analysis. The pooled results indicated that the incidences of reflux esophagitis of DTR, EG, GT, JI, JPI and DFT were 7.6%, 27.3%, 4.5%, 7.1%, 14.0%, and 9.1%, respectively. The EG group had more reflux esophagitis (OR = 3.68, 95%CI 2.44-5.57, P < 0.00001) and anastomotic stricture (OR = 1.58, 95%CI 1.02-2.45, P = 0.04) than the EJ group. But the EG group showed shorter operation time (MD=-56.34, 95%CI -76.75- -35.94, P < 0.00001), lesser intraoperative blood loss (MD=-126.52, 95%CI -187.91- -65.12, P < 0.0001) and shorter postoperative hospital stay (MD=-2.07, 95%CI -3.66- -0.48, P = 0.01). Meanwhile, the EG group had fewer postoperative complications (OR = 0.68, 95%CI 0.51-0.90, P = 0.006) and lesser weight loss (MD=-1.25, 95%CI -2.11- -0.39, P = 0.004). For specific reconstruction methods, there were lesser reflux esophagitis (OR = 0.10, 95%CI 0.06-0.18, P < 0.00001) and anastomotic stricture (OR = 0.14, 95%CI 0.06-0.33, P < 0.00001) in DTR than the esophagogastrostomy. DTR and esophagogastrostomy showed no significant difference in anastomotic leakage (OR = 1.01, 95%CI 0.34-3.01, P = 0.98). CONCLUSION: Esophagojejunal anastomosis after proximal gastrectomy can reduce the incidences of reflux esophagitis and anastomotic stricture, while esophagogastric anastomosis has advantages in technical simplicity and long-term weight status. Double tract reconstruction is a safe technique with excellent anti-reflux effectiveness and favorable quality of life. REGISTRATION: This meta-analysis was registered on the PROSPERO (CRD42022381357).

[New-onset postoperative atrial fibrillation following coronary artery bypass grafting: Incidence, clinical course and short-term outcomes].

INTRODUCTION: The aims of this retrospective study were to investigate the incidence, clinical course and short term outcomes of new-onset postoperative atrial fibrillation (POAF) following coronary artery bypass surgery (CABG). MATERIALS AND METHODS: A nation-wide study on 1622 patients who underwent CABG from 2006-2020 at Landspitali University Hospital. Clinical data were extracted from registries and 121 patients with pre-existing AF excluded, leaving 1501 patients for further analysis. Patient charts and postoperative ECGs were manually reviewed for determining details of POAF, which was defined as a postoperative episode of AF before discharge lasting at least 5 minutes. Patients with POAF (n=483) were compared to non-POAF patients (n=1018). RESULTS: Altogether 483 (32.2%) patients developed POAF; the annual incidence decreasing over time (tau= -0,45, p=0.023). Most patients were diagnosed on the second day postoperatively (43.5%) and over 90% were diagnosed within 4 days. The median number of POAF episodes was 3 (IQR: 1-5), the first episode lasting 1-6 hours in half of the cases and the total POAF-duration being 12 hours median (IQR: 5-30). Over 94% of cases converted to sinus rythm before discharge, with 25 (5.3%) patients being discharged in AF. Most patients were treated with beta-blockers (98.8%), amiodarone (95%) and 14.9% with electric cardioversion. POAF-patients were older, had higher EuroSCORE II and a longer hospital stay, however, they had similar rates of early postoperative stroke and 30 day mortality. CONCLUSION: The incidence of POAF remains high and was associated with prolonged hospital stay, but not significantly higher 30 day mortality or early postoperative stroke compared to patients in sinus rhythm. POAF-episodes were predominantly transient and almost 95% of patients were discharged in sinus rythm.

The Response of Synthetic Adrenocorticotropic Hormone (ACTH) Treatment in Pediatric Drug-Resistant Epilepsy Other Than Infantile Epileptic Spasms Syndrome: A Retrospective Observational Study.

INTRODUCTION:  Adrenocorticotropic hormone (ACTH) is a tropic hormone naturally secreted by the anterior pituitary gland to stimulate the secretion of cortisol and androgens. ACTH is used in non-tuberous sclerosis infantile epileptic spasms syndrome (IESS), and it has shown significant, promising results in epilepsy syndromes with possible inflammatory processes. However, many studies have also demonstrated a promising potential even in other types of drug-resistant epilepsy.  Material and method: This study is a retrospective observational study that follows the clinical characteristics and outcomes of nine pediatric patients with drug-resistant epilepsy treated with short-term synthetic ACTH in Saudi Arabia. The response was assessed during the ACTH infusion and after three months. RESULTS: During infusion, six of the nine (66%) patients had a short-term (within two weeks) favorable response, with a more than 50% reduction in seizure frequency. Four of the nine (44%) patients had complete responses with seizure freedom. After three months, four patients (44%) had a three-month seizure frequency reduction of more than 30% attributed to ACTH, including one patient with an IESS history who had a 70% reduction in seizure frequency. Of the four patients who had a complete response, three (75%) had a seizure relapse after tapering in the following three months.  Conclusion: This case series adds to the literature to suggest ACTH treatment of drug-resistant epilepsies other than IESS might benefit some patients in the acute setting but they are less likely to maintain a sustained treatment response. Randomized and large sample size studies are necessary to assess treatment response and accurately aid in appropriate patient selection.

Weekend effect on the incidence and outcomes of cardiac surgery associated - acute kidney injury.

BACKGROUND: The effects of surgical day (workdays or weekends) on occurrence and outcome of cardiac surgery associated -acute kidney injury (CSA-AKI) remains unclear. This study aimed to compare the incidence and short-term outcomes of CSA-AKI in patients undergoing surgery on workdays and weekends. MATERIALS AND METHODS: Patients who underwent cardiac surgery from July 2020 to December 2020 were retrospectively enrolled in this study. These patients were divided into a weekend group and workday group. The primary endpoint was the incidence of CSA-AKI. The secondary endpoints included renal function recovery and in-hospital mortality. The logistic regression model was used to explore the risk factors for CSA-AKI. Stratification analysis was performed to estimate the association between CSA-AKI and weekend surgery stratified by emergency surgery. RESULTS: A total of 1974 patients undergoing cardiac surgery were enrolled. The incidence of CSA-AKI in the weekend group was significantly higher than that in the workday group (42.8% vs. 34.7%, P = 0.038). Further analysis of patients with CSA-AKI showed that there was no difference in renal function recovery between the workday AKI group and weekend AKI group. There was no difference in in-hospital mortality between the weekend group and workday group (3.6% vs. 2.4%, P = 0.327); however, the in-hospital mortality of the weekend AKI group was significantly higher than that of the workday AKI group (8.5% vs. 2.9%, P = 0.014). Weekend surgery and emergency surgery were independent risk factors for CSA-AKI. The multiplicative model showed an interaction between weekend surgery and emergency surgery; weekend surgery was related to an increased risk of AKI among patients undergoing emergency surgery [adjusted OR (95% CI): 1.96 (1.012-8.128)]. CONCLUSIONS: The incidence of CSA-AKI in patients undergoing cardiac surgery on weekends was significantly higher compared to that in patients undergoing cardiac surgery on workdays. Weekend surgery did not affect the in-hospital mortality of all patients but significantly increased the mortality of AKI patients. Weekend surgery and emergency surgery were independent risk factors for CSA-AKI. Weekend emergency surgery significantly increased the risk of CSA-AKI.

Case report: Traumatic hemorrhagic cervical myelopathy in a dog.

A 1.5-year-old female entire French bulldog was referred for neurological evaluation, further diagnostic tests, and treatment 24 h after a road traffic accident. Initial emergency treatment, diagnostic tests, and stabilization had been performed by the referring veterinarian. Neurological examination revealed severe spastic non-ambulatory tetraparesis and was consistent with a C1-5 myelopathy. A magnetic resonance imaging (MRI) study revealed an irregular to elongated ovoid intramedullary lesion centered over the body of C2. The lesion showed marked signal heterogeneity with a central T2W and T2* hyperintense region, surrounded by a hypointense rim on both sequences. The lesion appeared heterogeneously T1W hypointense. The lesion was asymmetric (right-sided), affecting both white and gray matter. The C2-3 intervertebral disk appeared moderately degenerate with a Pfirrmann grade of 3. No evidence of vertebral fracture or luxation was found on radiographs or MRI of the vertebral column. Additional soft tissue abnormalities in the area of the right brachial plexus were suggestive of brachial plexus and muscle injury. A diagnosis of traumatic hemorrhagic myelopathy at the level of C2 and concurrent brachial plexus injury was formed. Conservative treatment was elected and consisted of physiotherapy, bladder care with an indwelling urinary catheter, repeated IV methadone based on pain scoring (0.2 mg/kg), oral meloxicam 0.1 mg/kg q24h, and oral gabapentin 10 mg/kg q8h. The dog was discharged after 4 days, with an indwelling urinary catheter and oral medication as described. The catheter was replaced two times by the referring veterinarian and finally removed after 10 days. Thereafter, voluntary urination was seen. During the 2 months after the road traffic accident, slow recovery of motor function was seen. The right thoracic limb recovery progressed more slowly than the left limb, also showing some lower motor neuron signs during follow-up. This was judged to be consistent with a right-sided brachial plexus injury. The dog was reported ambulatory with mild residual ataxia and residual monoparesis of the right thoracic limb at the last follow-up 3 months post-injury. This case report highlights the MRI-based diagnosis of traumatic hemorrhagic myelopathy in a dog. A fair short-term outcome was achieved with conservative treatment in this case.

Takotsubo syndrome before and during the COVID-19 pandemic in Austria: a retrospective cohort study (TOSCA-19).

AIMS: This study aims to investigate the prevalence of Takotsubo syndrome (TTS) as a percentage of the total number of acute coronary syndrome (ACS), including non-STE-elevation myocardial infarction and ST-elevation myocardial infarction, as well as the short-term outcome of TTS patients before and during the COVID-19 pandemic. METHODS AND RESULTS: We compared patients from two different periods: (i) Period 1 (before the COVID-19 pandemic): 1 March to 30 December 2019, and (ii) Period 2 (during the COVID-19 pandemic): 1 March to 30 December 2020. The retrospective database was created from the archives of the participating hospitals or electronic hospital systems by trained medical personnel. The subjects' medical history, cardiovascular risk factors, laboratory values, echocardiography findings, and an in-hospital outcome were variables of interest. Furthermore, propensity score matching analysis was performed to evaluate the short-term prognosis in TTS and ACS patients. Altogether six Austrian centres-(i) 3rd Medical Department of Cardiology and Intensive Care Medicine, Clinic Ottakring, Vienna, Austria; (ii) 5th Medical Department of Cardiology, Clinic Favoriten, Vienna, Austria; (iii) 2nd Medical Department, Hanusch Hospital, Vienna, Austria; (iv) University Clinic of Internal Medicine III, Cardiology and Angiology, Medical University of Innsbruck, Austria; (v) Department of Cardiology, University Hospital Graz, Graz, Austria; (vi) Department of Cardiology and Intensive Medicine, Kepler University Clinic, Linz, Austria-participated in the study. During period 1, 87 (3.5%) patients out of 2482 ACS patients had TTS in all participating centres. During period 2, 71 (2.7%) patients out of 2572 ACS patients had TTS in all participating centres. Accordingly, the prevalence of TTS remained stable irrespective of potential psychologic stress during the COVID pandemic. Furthermore, the baseline characteristics of TTS patients did not change during the COVID-19 pandemic. The prevalence of in-hospital complications [cardiogenic shock (4.6% vs. 4.3%, P = 0.925), ventricle thrombus (1.1% vs. 1.4%, P = 0.885) and in-hospital bleeding (3.4% vs. 1.4%, P = 0.417)] remained stable. The all-cause in-hospital mortality of TTS patients did not change during the COVID-19 pandemic [χ2 (2) = 0.058, P = 0.810]. Moreover, a propensity score matching analysis of all-cause in-hospital mortality between matched TTS and ACS patients showed higher in-hospital mortality in ACS patients during COVID-19 pandemic (P = 0.043). CONCLUSIONS: Despite the well-known increased psychologic stress during the COVID-19 pandemic, the prevalence of TTS during the COVID-19 pandemic and the short-term clinical outcome in Austria remained unimpacted.

Surgeon's Experience May Circumvent Operative Volume in Improving Early Outcomes After Pancreaticoduodenectomy.

Introduction Pancreaticoduodenectomy (PD) is a complex procedure with a significant proportion of postoperative complications and improving but notable mortality. PD was the prototype procedure that initiated the lingering debate about the relationship of better operative outcomes when performed at higher-volume centers. This has not translated into practice. Impediments include the absence of a universally accepted definition of a high-volume center among others. Contrary evidence suggests equivalent outcomes for PD at low-volume centers when performed by experienced hepatobiliary surgeons. We reviewed our perioperative outcomes for PD from an earlier period as a low-volume center with an experienced team. Methods A longitudinal study of all PDs completed in our department between 2012 and 2017 was performed. Results A total of 28 PD were performed during this period. Pylorus-preserving PD was performed in 23 patients and classical PD in the remaining. A separate Roux-en-Y loop was used for high-risk pancreatic anastomosis in six cases. The mean patient age was 49.3±12.4 years. The male-to-female ratio was 1.3:1. Preoperative drainage procedures were carried out in 19 patients. The mean serum total bilirubin level was 3.98(±4.5) mg/dL. There was no 90-day mortality. Postoperative complications included wound infection in 10 (36.7%) and respiratory complications in 10 (36.7%) patients. Postoperative bleeding requiring intervention occurred in one patient, and two patients had an anastomotic leak (one pancreatojejunostomy (PJ) and one gastrojejunostomy (GJ)). Delayed gastric emptying (DGE) was noted in three (10.7%) patients. The mean length of hospital stay was 14±7 days. The median overall survival (OS) was 84 months. Conclusion Comparable early outcomes can be achieved at low-volume centers for patients undergoing PD with an experienced team, optimal patient selection, and the ability to rescue for complications.

Distal Tibiofibular Joint Reconstruction Using Autograft in a Rare Case of Lower Limb Sclerosing/Spindle Cell Rhabdomyosarcoma: A Two-Year Follow-Up.

Sclerosing/spindle cell rhabdomyosarcoma (s-scRMS) is a rare variant of striated muscle tumours. It has been recognised as an individual entity, the fourth subtype of rhabdomyosarcoma in the latest WHO classification. In the paediatric population, it occurs more commonly in the paratesticular area, whereas in adults, it occurs more commonly in the head and neck region. It has distinctive characteristics in terms of its histopathological and immunochemistry findings, which help in accurate diagnosis. The mainstay of treatment is a multimodal approach, i.e., surgery, chemotherapy, and radiation therapy. However, no standard care is still being established internationally for adult cases. In adults, this tumour has a poorer prognosis as compared to children. We describe a patient with s-scRMS of the lower limb who has undergone wide local resection of the tumour with surgical reconstruction of the distal tibiofibular joint with autograft and its two-year outcome.

A dyadic session-by-session assessment of therapeutic alliance and short-term outcome among clients with schizophrenia in comparison with clients with emotional disorders.

OBJECTIVE: Although the clinical significance of the therapeutic alliance (TA) is well documented, the literature regarding the establishment of TA and the relation between client-therapist agreement on it to short-term outcome among various diagnostic groups-and specifically among clients diagnosed with serious mental illness (SMI)-is sparse. The aim of the present study was to examine the effect of client diagnosis on the abovementioned TA characteristics. METHOD: Dyadic analyses of session-by-session (SBS) data were used to compare clients diagnosed with schizophrenia and clients diagnosed with emotional disorders (based on a clinical interview) in their TA characteristics. RESULTS: TA as initially rated by clients was stronger in the emotional disorders group than in the schizophrenia group. Higher TA ratings, regardless of whether these were provided by the therapist or the client, predicted better subsequent functioning in the emotional disorders group, whereas in the schizophrenia group, this association was observed only among good-outcome cases. CONCLUSIONS: Establishing TA, having client-therapist agreement on it, and having clients derive therapeutic benefit from it might be more challenging with clients with schizophrenia than with clients with emotional disorders. Special attention should be given to specific challenges and needs regarding clients' diagnosis in order to enhance favourable therapy outcomes.
