Endovascular treatment of patients with distal aneurysms of cerebellar arteries

Aim. To evaluate short- and long‑term angiographic and clinical outcomes of endovascular treatment of patients with distal aneurysms of cerebellar arteries.Materials and methods. The outcomes of endovascular treatment of 6 patients with distal aneurysms of cerebellar arteries who underwent surgery at the Neurosurgical Division No. 3 of the Polenov Russian Research Institute of Neurosurgery between January 1 of 2017 and March 31 of 2023 were analyzed.Results. The following endovascular methods were used: occlusion of the aneurysm sac using only detachable coils (n = 2); occlusion using stent‑assisted coiling (n = 3); deconstructive intervention with occlusion of the main artery (n = 1). In 1 of 2 cases of coil‑only aneurysm occlusion, additional stent‑assisted occlusion was performed due to recurrence. Among 6 aneurysms, 1 (16.65 %) aneurysm was radically excluded from the blood flow (class А); 4 (66.7 %) were excluded subtotally (class B); 1 (16.65 %) was excluded partially (class С). Control angiography at least 6 months after showed radical exclusion of the aneurysm from the blood flow (class A) in 5 (83.3 %) patients, subtotal exclusion (class В) in 1 (16.7 %) patient. Clinical outcome was excellent in 5 (83.3 %) patients (0 points per the modified Rankin scale); in 1 patient after deconstructive surgery, augmentation of neurological symptoms with following partial regression was observed (2 points per the modified Rankin scale). Complications during deconstructive surgery were observed in 1 (16.7 %) patient.Conclusion. Deconstructive surgery of the distal aneurysms of cerebellar arteries can be associated with high risk of postoperative ischemic complications with development of persisting neurological deficit. Surgical interventions with preservation of the artery lumen (including reconstructive surgeries) should be the method of choice in endovascular treatment of distal aneurysms of cerebellar arteries due to minimal risk of ischemic complications and improved clinical outcomes of surgical treatment.

Effect of endoscopic full-thickness resection assisted by distal serosal turnover with floss traction for gastric submucosal masses

BACKGROUND Complex and high-risk surgical complications pose pressing challenges in the clinical implementation and advancement of endoscopic full-thickness resection (EFTR). Successful perforation repair under endoscopy, thereby avoiding surgical intervention and postoperative complications such as peritonitis, are pivotal for effective EFTR. AIM To investigate the effectiveness and safety of EFTR assisted by distal serosal inversion under floss traction in gastric submucosal tumors. METHODS A retrospective analysis of patients with gastric and duodenal submucosal tumors treated with EFTR assisted by the distal serosa inversion under dental floss traction from January 2023 to January 2024 was conducted. The total operation time, tumor dissection time, wound closure time, intraoperative bleeding volume, length of hospital stay and incidence of complications were analyzed. RESULTS There were 93 patients, aged 55.1 ± 12.1 years. Complete tumor resection was achieved in all cases, resulting in a 100% success rate. The average total operation time was 67.4 ± 27.0 min, with tumor dissection taking 43.6 ± 20.4 min. Wound closure times varied, with gastric body closure time of 24.5 ± 14.1 min and gastric fundus closure time of 16.6 ± 8.7 min, showing a significant difference (P < 0.05). Intraoperative blood loss was 2.3 ± 4.0 mL, and average length of hospital stay was 5.7 ± 1.9 d. There was no secondary perforation after suturing in all cases. The incidence of delayed bleeding was 2.2%, and the incidence of abdominal infection was 3.2%. No patient required other surgical intervention during and after the operation. CONCLUSION Distal serosal inversion under dental-floss-assisted EFTR significantly reduced wound closure time and intraoperative blood loss, making it a viable approach for gastric submucosal tumors.

Complications after gender-affirming chest masculinization surgery do not impact patient satisfaction

Chest masculinization surgery is an increasingly common procedure and has offered significant benefits to the gender-diverse community. Although major complications are an infrequent occurrence in chest masculinization surgery, they may still impact surgical success. While the long-term success of chest masculinization surgery has been examined through patient-reported outcome measures, there is no study that has assessed the association between complications and patient-reported outcomes. In this study, patients who underwent double incision or periareolar mastectomies for chest masculinization by a single surgeon were surveyed. Demographic, operative, and postoperative variables were obtained from medical records. The BODY-Q and SCAR-Q modules (Q-Portfolio.org) were used to assess postoperative patient-reported outcomes. There were 151 survey responders (43% response rate), 132 without complications and 19 with complications. No significant differences in patient-reported outcomes were noted when comparing the groups with and without complications. While some providers may be reluctant to offer chest masculinization to patients they deem high risk for complications, patients and providers should be assured that complications do not significantly impact patient satisfaction. LAY SUMMARY: Gender-affirming chest masculinization surgery is increasingly common. We investigated the impact of complications on patient-reported outcomes in chest masculinization. Patients and providers should be assured that complications do not significantly impact patient satisfaction.

Associations of body composition parameters with postoperative outcome and perineural tumour invasion after oncological pancreatic resection

BackgroundPancreatic cancer is often accompanied by wasting conditions. While surgery is the primary curative approach, it poses a substantial risk of postoperative complications, hindering subsequent treatments. Therefore, identifying patients at high risk for complications and optimizing their perioperative general condition is crucial. Sarcopenia and other body composition abnormalities have shown to adversely affect surgical and oncological outcomes in various cancer patients. As most pancreatic tumours are located close to the neuronal control centre for the digestive tract, it is possible that neural infiltration in this area deranges bowel functions and contributes to malabsorption and malnutrition and ultimately worsen sarcopenia and weight loss.MethodsA retrospective analysis of CT scans was performed for pancreatic cancer patients who underwent surgical tumour resection at a single high-volume centre from 2007 to 2023. Sarcopenia prevalence was assessed by skeletal muscle index (SMI), and visceral obesity was determined by the visceral adipose tissue area (VAT). Obesity and malnutrition were determined by the GLIM criteria. Sarcopenic obesity was defined as simultaneous sarcopenia and obesity. Postoperative complications, mortality and perineural tumour invasion, were compared among patients with body composition abnormalities.ResultsOf 437 patients studied, 46% were female, the median age was 69 (61;74) years. CT analysis revealed 54.9% of patients with sarcopenia, 23.7% with sarcopenic obesity and 45.9% with visceral obesity. Sarcopenia and sarcopenic obesity were more prevalent in elderly and male patients. Postoperative surgical complications occurred in 67.7% of patients, most of which were mild (41.6%). Severe complications occurred in 22.7% of cases and the mortality rate was 3.4%. Severe postoperative complications were significantly more common in patients with sarcopenia or sarcopenic obesity. Visceral obesity or malnutrition based on BMI alone, did not significantly impact complications. Perineural invasion was found in 80.1% of patients and was unrelated to malnutrition or body composition parameters.ConclusionsThis is the first and largest study evaluating the associations of CT-based body mass analysis with surgical outcome and histopathological perineural tumour invasion in pancreatic cancer patients. The results suggest that elderly and male patients are at high risk for sarcopenia and should be routinely evaluated by CT before undergoing pancreatic surgery, irrespective of their BMI. Confirmation of the results in prospective studies is needed to assess if pancreatic cancer patients with radiographic sarcopenia benefit from preoperative amelioration of muscle mass and function by exercise and nutritional interventions.

Effectiveness of the flash glucose monitoring system in preventing severe hypoglycemic episodes and in improving glucose metrics and quality of life in subjects with type 1 diabetes at high risk of acute diabetes complications

AimsTo assess the effectiveness of the intermittent-scanned continuous glucose monitoring (isCGM) system in preventing severe hypoglycemic episodes and in improving glucose parameters and quality of life.MethodsFour hundred T1D individuals were enrolled in a prospective real-word study with an intermittently scanned continuous glucose monitoring device during the 12-months follow-up. The primary endpoint was the incidence of severe hypoglycemic events.Results82% of subjects were naïve to the use of the device (group A) and 18% were already wearing the system (group B). The cumulative incidence of severe hypoglycemia (SH) at 12 months was 12.06 per 100 person-year (95% CI: 8.35–16.85) in group A and 10.14 (95% CI: 4.08–20.90) in group B without inter-group differences. In group A there was a significant decrease in SH at 12 months compared to 3 months period (p = 0.005). Time in glucose range significantly increased in both groups accompanied with a significant decrease in glucose variability. HbA1c showed a progressive significant time-dependent decrease in group A. The use of the device significantly improved the perceived quality of life.ConclusionThis study confirmed the effectiveness of the isCGM in reducing hypoglycemic risk without glucose deterioration, with potential benefits on adverse outcomes in T1D individuals.Trial registration: ClinicalTrials.gov registration no. NCT04060732.

Robot-assisted Partial Nephrectomy for Hilar and Nonhilar Renal Masses: Comparison of Perioperative, Oncological, and Functional Results in a Multicentre Prospective Cohort (NEPRAH Study, UroCCR 175)

Background and objectiveA hilar location for a renal tumour is sometimes viewed as a limiting factor for safe partial nephrectomy. Our aim was to evaluate perioperative, oncological, and functional outcomes of robot-assisted partial nephrectomy (RAPN) for hilar tumours (RAPN-H) in comparison to RAPN for nonhilar tumours (RAPN-NH). MethodsWe conducted an observational, multicentre cohort study using prospectively collected data from the French Research Network on Kidney Cancer (UroCCR). The registry includes data for 3551 patients who underwent RAPN for localised or locally advanced renal masses between 2010 and 2023 in 29 hospitals in France. We studied the impact of a hilar location on surgery, postoperative renal function, tumour characteristics, and survival. We also compared rates of trifecta achievement (warm ischaemia time [WIT] <25 min, negative surgical margins, and no perioperative complications) between the groups. Finally, we performed a subgroup analysis of RAPN without vascular clamping. Variables were compared in univariable analysis and using multivariable linear, logistic, and Cox proportional-hazards models adjusted for relevant patient and tumour covariates. Key findings and limitationsThe analytical population included 3451 patients, of whom 2773 underwent RAPN-NH and 678 underwent RAPN-H. Longer WIT (β = 2.4 min; p < 0.01), longer operative time (β = 11.4 min; p < 0.01) and a higher risk of postoperative complications (odds ratio 1.33; p = 0.05) were observed in the hilar group. Blood loss, the perioperative transfusion rate, postoperative changes in the estimated glomerular filtration rate, and trifecta achievement rates were comparable between the groups (p > 0.05). At mean follow-up of 31.9 mo, there was no significant difference in recurrence-free survival (hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.58–1.2; p = 0.3), cancer-specific survival (HR 1.1, 95% CI 0.48–2.6; p = 0.79), or overall survival (HR 0.89, 95% CI 0.52–1.53; p = 0.69). Conclusions and clinical implicationsPatient and tumour characteristics rather than just hilar location should be the main determinants of the optimal surgical strategy for hilar tumours. Patient summaryWe found that kidney tumours located close to major kidney blood vessels led to a longer operation and a higher risk of complications during robot-assisted surgery to remove the tumour. However, tumours in these locations were not related to a higher risk of kidney function loss, cancer recurrence, or death.

The experiences and perceptions of rural and remote nurses who provide care to pregnant women in the absence of midwives.

Maternity unit closures in rural and remote settings of Australia have left a substantial gap in services for pregnant women. In the absence of midwives, and when women are unable to attend a maternity facility, registered nurses (RNs) are required to fill the void. While maternity education can attempt to prepare RNs for such encounters, there is little documented to suggest it meets all their physical and psychological needs. The existing challenges for health professionals, practising a vast generalist scope of practice while living and working in a rural and remote location, have been well researched and documented. How nurses feel about the expectation that they work outside their scope of practice to provide maternity care in a rural and remote setting in Australia has not been asked until now. This study explores the perceptions and experiences of RNs who find themselves in this situation. The study utilised a hermeneutic phenomenological methodology to examine the experiences and perceptions of rural and remote nurses providing care for pregnant women. RNs working in rural and remote health facilities that had no maternity services were recruited by a purposive sampling method. Semistructured conversational interviews were recorded and transcribed verbatim. Data analysis was guided by van Manen's analytical approach. Eight nurses participated, and from the data three themes, each with several subthemes, emerged: 'being-in-the-world of the rural and remote nurse' - described how participants viewed rural and remote nursing as an entity with unchangeable aspects that could not be considered in isolation; 'scope of practice - unprepared or underprepared' described how, despite their existing and extensive nursing skills, participants felt ill-equipped theoretically, practically and mentally to care for pregnant women; 'moral distress' - participants expanded their feelings of unpreparedness to include inadequacy, fear, and appropriateness of care delivery. The realism of rural and remote nursing practice demonstrates that at some point in their career, rural and remote nurses will care for a labouring and/or pregnant woman at high risk for complications. Participants in this study appeared open and honest in their interviews, displaying pride at their extensive nursing skills and job satisfaction. However, they were unanimous in their discussions of what being a nurse and providing maternity care in a rural and remote setting meant to themselves and to pregnant women. They suggested care was fragmented and inadequate from a workforce that is inadequately prepared and stressed. This study has highlighted another concerning aspect of rural and remote midwifery care - the experiences and perceptions of eight nurses delivering care that has previously been overlooked. The united voice of the RNs in this study warrants a platform to speak from and deserves acknowledgement and attention from government and midwifery policy drivers. These nurses, and the women receiving their care, deserve more.

Cobimetinib plus atezolizumab for RAS and NF1/2-mutated poorly differentiated thyroid carcinoma.

6106 Background: Poorly differentiated thyroid carcinomas (PDTC) are a subset of thyroid cancers characterized by high-grade pathologic features. They hold an intermediate position on the spectrum of follicular-derived thyroid cancers. Due to their more aggressive clinical behavior, PDTCs typically exhibit shorter responses to the usual kinase inhibitors (KIs) used in advanced differentiated thyroid cancers and develop resistance earlier on. In fact, median progression free survival (PFS) with single-agent lenvatinib in patients with PDTC in the SELECT trial (n=28) was 14.8 months. Although there are increasing data to support the use of immunotherapy plus KI combinations in anaplastic thyroid cancer, evidence demonstrating the efficacy of this strategy in PDTC is sparse. We aimed to study the safety and efficacy of atezolizumab combined with KIs in PDTC. Methods: We enrolledpatientswith PDTC in a single-center phase II prospective trial of atezolizumab plus mutation-determined targeted therapy (NCT03181100). Patients with RAS or NF- mutated tumors were treated with atezolizumab plus the MEK inhibitor (MEKi) cobimetinib. Primary outcome was median overall survival (mOS). Best response to therapy was assessed per RECIST v1.1; survival by the Kaplan-Meier method. Results: Eight patients with RAS/NF-mutated PDTC were enrolled. Median age at treatment start was 68.5 years. All patients had distant metastatic disease at time of enrollment. Prior to study entrance, 7/8 patients (88%) had surgical resection of the primary tumor, 6/8 (75%) radioactive iodine, 2/8 (25%) external beam radiation to the neck, and 3/8 (38%) bridging cytotoxic chemotherapy. All patients were naïve to KIs. Six (75%) patients had RAS mutations (1 HRAS, 3 KRAS, 2 NRAS) and 3 (38%) had NF mutations (2 NF1, 1 NF2). One patient’s tumor harbored both KRAS and NF2 mutations at baseline. PD-L1 score was positive in 3/4 evaluable specimens. Median duration of follow-up was 65 months. Best response to therapy was stable disease in 6/8 (75%), partial response in 1/8 (12.5%) and progressive disease in 1/8 (12.5%). mOS was 23 months (95% CI, 12.8 – 33.2) and median PFS was 7 months (95% CI, 2.4 – 11.6). 4/8 patients received radioactive iodine (RAI) while on systemic therapy. Median dose of RAI was 149 millicuries (range, 108 – 153). mOS was significantly longer in patients who received RAI (32 vs 16 months; p= 0.034). The combination of cobimetinib + atezolizumab was overall well tolerated, with an expected adverse event profile. Conclusions: In patients with metastatic PDTC driven by RAS or NFmutations, combination of the anti-PD-L1 atezolizumab with MEKi cobimetinib showed some clinical efficacy, although PFS was shorter than with single-agent lenvatinib. However, SELECT trial did not delineate responses by driver mutations. This combination could thus be considered in selected patients at high risk of complications with antiangiogenic KIs. Clinical trial information: NCT03181100 .

A rare hemoglobinopathy duo: Hb Adana×Hb SEA in a 1-year-old patient – a case report and a brief literature review

Introduction and importance: Alpha thalassemia, resulting from nondeletional mutations, typically presents a more severe clinical manifestation compared to deletional mutations. Severe outcomes, such as hydrops fetalis, are associated with two specific nondeletional mutations. Therefore, DNA-based investigation is crucial for suspected carriers exhibiting subtle hematological abnormalities to facilitate proper diagnosis and effective family counseling. Case presentation: In this report, the authors describe a phenotypically normal 1-year-old girl with a rare and unique alpha-thalassemia genotype due to the presence of Hb Adana, a nondeletional alpha-chain mutation compounded with Hb SEA, an alpha-globin gene deletion. Clinical discussion: Mutations determine the clinical manifestations of alpha-thalassemia. DNA testing is recommended for suspected carriers with relatively small hematological abnormalities, for precise diagnosis and family counseling. To provide clinicians with a reference for diagnostic assessment, the authors established a genotype-phenotype correlations based on reported cases of Hb Adana following an exhaustive literature review. Being interested in determining which ethnicities and genotypes are associated with a higher risk of complications, including hydrops fetalis and transfusion dependence, the authors formalized a diagnostic evaluation guide and a guide for early screening to improve outcomes. Conclusion: Precise genetic evaluation is important for the diagnosis of alpha thalassemia. Hematologists play a critical role in managing these disorders, understanding genotype-phenotype correlations, and highlighting the significance of genetic counseling for high-risk patients. Extensive studies on these various genophenotypes are required to improve the diagnosis and prognosis of such medical conditions and advocate preventative strategies.

Suboptimally Controlled Diabetes in Pregnancy: A Review to Guide Antepartum and Delivery Management.

Diabetes mellitus is one of the most common complications in pregnancy with adverse maternal and neonatal risks proportional to the degree of suboptimal glycemic control, which is not well defined. Literature guiding providers in identifying and managing patients at highest risk of complications from diabetes is lacking. This article reviews the definition, epidemiology, and pathophysiology of suboptimal control of diabetes in pregnancy, including "diabetic fetopathy"; explores proposed methods of risk stratification for patients with diabetes; outlines existing antepartum management and delivery timing guidelines; and guides direction for future research. Original research articles, review articles, and professional society guidelines on diabetes management in pregnancy were reviewed. The reviewed available studies demonstrate worsening maternal and neonatal outcomes associated with suboptimal control; however, the definition of suboptimal based on parameters followed in pregnancy such as blood glucose, hemoglobin A1c, and fetal growth varied from study to study. Studies demonstrating specific associations of adverse outcomes with defined suboptimal control were reviewed and synthesized. Professional society recommendations were also reviewed to summarize current guidelines on antepartum management and delivery planning with respect to diabetes in pregnancy. The literature heterogeneously characterizes suboptimal glucose control and complications related to this during pregnancy in individuals with diabetes. Further research into antepartum management and delivery timing for patients with varying levels of glycemic control and at highest risk for diabetic complications is still needed.

Tracheostomy Incidence and Complications: A National Database Analysis.

To describe the incidence of tracheostomy-related complications and identify prognostic risk factors. Administrative database analysis. Outpatient and inpatient insurance claims records obtained from a national database. PearlDiver, a private analytics database of insurance claims from Medicare, Medicaid, and commercial insurance companies, was used to identify patients who underwent tracheostomies and associated complications between January 2010 and October 2021 by CPT and ICD-9/ICD-10 codes. A total of 198,143 tracheostomies were identified from PearlDiver, and at least 1 tracheostomy-related complication occurred within 90 days of the procedure in 22,802 (10.3%) of these cases. The proportion of tracheostomy-related complications was 2.3 times higher in 2019 compared to 2010 (95% confidence interval [CI]: 2.18-2.52). The risk of developing tracheostomy-complications was associated with the hospital region (highest in the Midwest as compared to the West [odds ratio [OR] = 1.32; 95% CI: 1.25-1.39]), provider specialty (highest for otolaryngologists as compared to nonsurgical physicians [OR = 2.22; 95% CI: 2.10-2.34]), insurance plan type (lowest for cash payment compared to Medicaid [OR = 0.70, 95% CI: 0.50-0.94]), and Elixhauser Comorbidity Index (ECI) (highest in patients with ECI of 7+ compared to 0-1 [OR = 2.96; 95% CI: 2.17-3.24]), but was not significantly associated with patient age (OR = 0.99; 95% CI: 0.99-0.99), or gender (OR = 1.04; 95% CI: 1.01-1.07). Complications after tracheostomy are common and sicker patients are at higher risk for complications. Identifying factors associated with increased risk for complications could help to improve patient and family counseling, guide quality improvement initiatives, and inform future studies on tracheostomy outcomes.

Anticoagulant Therapy in Pregnant Women with Mechanical Heart Valves: Italian Federation of Centers for Diagnosis and Surveillance of the Antithrombotic Therapies (FCSA) Position Paper.

The management of anticoagulant therapy in pregnant women with mechanical heart valves (MHVs) is difficult and often challenging even for clinicians experienced in the field. These pregnancies, indeed, are burdened with higher rates of complications for both the mother and the fetus, compared to those in women without MHVs. The maternal need for an optimal anticoagulation as provided by vitamin K antagonists is counterbalanced by their teratogen effect on the embryo and fetus. On the other hand, several concerns have been raised about the efficacy of heparins in pregnant women with MHVs, considering the high risk of thrombotic complications in these patients. Therefore, numerous clinical issues about the management of pregnant women with MHVs remain unanswered, such as the selection of the best anticoagulant agent, the optimal anticoagulation levels to be achieved and maintained, and the evaluation of long-term effects for both the mother and the fetus. Based on a comprehensive review of the current literature, the Italian Federation of the Centers for the Diagnosis and the Surveillance of the Antithrombotic Therapies (FCSA) proposes experience-based suggestions and expert opinions. Particularly, this consensus document aims at providing practical guidance for clinicians dealing with pregnant women with MHVs, to optimize maternal and fetal outcomes while guaranteeing adequate anticoagulation. Finally, FCSA highlights the need for the creation of multidisciplinary teams experienced in the management of pregnant women with MHVs during pregnancy, delivery, and postpartum, in order to better deal with such complex clinical issues and provide a comprehensive counseling to these patients.

Specialised Intensive Care Treatment Concepts for Severe Chest Trauma

This review covers key elements of the critical care management of patients with thoracic trauma. Contrast-enhanced chest computertomography remains the diagnostic modality of choice, as it is more sensitive than conventional chest imaging. Regarding risk stratification, special caution is required in older patients with thoracic trauma given their high risk for posttraumatic complications. In the case of respiratory insufficiency, an attempt of non-invasive ventilation techniques is justified in most patients due to potential treatment benefits. Achieving sufficient pain control is a fundamental goal of critical care management. In this regard, erector-spinae-block and paravertebral block present potentially advantageous alternatives to thoracic epidural anaesthesia. In stable patients, the placement of small-calibre chest tubes may be a beneficial approach compared with large-bore tubes. If surgical stabilization of rib fractures is indicated, it should be done as early as possible.

Evaluating the Differences of Wound Related Complications in Robotically Assisted Radical Cystectomy vs Open Radical Cystectomy

ObjectiveTo determine whether robotic assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) compared to open radical cystectomy (ORC) or RARC with extracorporeal urinary diversion (ECUD) would result in a decreased rate of surgical site complications. RARC has been shown to be non-inferior to ORC. Both RARC and ORC are complicated by a high rate of perioperative morbidity, including wound related complications, which may be decreased by a robotic approach with intracorporeal diversion. MethodsA retrospective review of our bladder cancer database for patients undergoing radical cystectomy from 2013 to 2021. Patients were stratified by surgical technique as RARC with ICUD vs. ORC vs. RARC with ECUD. Surgical site complications were measured at both 30 and 90-day intervals. ResultsOf the 269 patients, 127 (47.2%) had RARC with ICUD, 118 (43.7%) had ORC, and 24 (8.9%) had RARC with ECUD (mean ages 71.0, 69.5, 67.5 respectively). A comparison of the three groups demonstrated statistical significance at both the 30-day (p<0.001) and 90-day (p<0.001) timeframes for total surgical site complications, with RARC with ICUD having the fewest amount of patients experience a surgical site complication (0.8%) followed by ORC (25.4%) and RARC with ECUD (29.2%). ConclusionOverall, we observed lower surgical site complication rates among patients undergoing RARC with ICUD compared to patients who underwent ORC or RARC with ECUD. This study suggests that decreased surgical site complications may be one benefit of the minimally invasive approach particularly in patients at high risk for surgical site complications after radical cystectomy.

IntroductionIntraoperative opioids have been used for decades to reduce negative responses to nociception. However, opioids may have several, and sometimes serious, adverse effects. Cardiac surgery exposes patients to a high...

Postoperative revision, complication and economic outcomes of patients with reverse or anatomic total shoulder arthroplasty at one year: a retrospective, United States hospital billing database analysis

BackgroundData on the one-year postoperative revision, complication, and economic outcomes in a hospital setting after total shoulder arthroplasty (TSA) are sparse. MethodsA retrospective cohort study using the Premier Healthcare Database, a hospital-billing data source, evaluated one-year postoperative revision, complication, and economic outcomes of reverse (RTSA) and anatomic (ATSA) TSA for patients who underwent the procedure from 2015 until 2021. All-cause revisits, including revision-related events (categorized as either irrigation and débridement or revision procedures and device removals) and shoulder/non-shoulder complications were collected. The incidences and costs of these revisits were evaluated. Generalized linear models were used to evaluate the associations between patient characteristics and revision and complication occurrences and costs. ResultsAmong 51,478 RTSA and 34,623 ATSA patients (mean [standard deviation (SD)] ages RTSA 71.5 [8.1] years, ATSA 66.8 [9.0] years), one-year adjusted incidences of all-cause revisits, irrigation/débridement, revision procedures/device removals, and shoulder/non-shoulder complications were RTSA: 45.0% (95% confidence interval (CI): 44.6%-45.5%), 0.1% (95% CI: 0.1%-0.2%), 2.1% (95% CI: 2.0%-2.2%), and 17.8% (95% CI: 17.5%-18.1%) and ATSA: 42.3% (95% CI: 41.8%-42.9%), 0.2% (95% CI: 0.1%-0.2%), 1.9% (95% CI: 1.8%-2.1%), and 14.4% (95% CI: 14.0%-14.8%), respectively; shoulder-related complications were RTSA: 12.4% (95% CI: 12.1%-12.7%) and ATSA: 9.9% (95% CI: 9.6%-10.3%). Significant factors associated with a high risk of revisions and complications included, but were not limited to, chronic comorbidities and noncommercial insurance. Per patient, the mean (SD) total one-year hospital cost was $25,225 ($15,911) and $21,520 ($13,531) for RTSA and ATSA, respectively. Revision procedures and device removals were most costly, averaging $22,920 ($18,652) and $26,911 ($18,619) per procedure for RTSA and ATSA, respectively. Patients with revision-related events with infections had higher total hospital costs than patients without this event (RTSA: $60,887 (95% CI: $56,951-$64,823) and ATSA: $59,478 (95% CI: $52,312-$66,644)), equating to a mean difference of $36,148 with RTSA and $38,426 with ATSA. Significant factors associated with higher costs of revision-related events and complications included age, race, chronic comorbidities, and noncommercial insurance. ConclusionsNearly 45% RTSA and 42% ATSA patients returned to the hospital, most often for shoulder/non-shoulder complications (overall 17.8% RTSA and 14.4% ATSA, and shoulder-related 12.4% RTSA and 9.9% ATSA). Revisions and device removals were most expensive ($22,920 RTSA and $26,911 ATSA). Infection complications requiring revision had the highest one-year hospital costs (∼$60,000). This study highlights the need for technologies and surgical techniques that may help reduce TSA healthcare utilization and economic burden.

Beyond Mortality: Severely Frail Femur Fracture Patients Can Regain Independence after Surgery.

Objectives: Little is known about the post-operative functional outcomes of severely frail femur fracture patients, with previous studies focusing on complications and mortality. This study investigated patient- or proxy-reported outcomes after femur fracture surgery in older adult patients with severe frailty. Methods: This was a retrospective cross-sectional study of older adult (>70 years) patients with severe frailty (defined by a Comprehensive Geriatric Assessment-based Frailty Index (FI-CGA) ≥ 0.40), who underwent femur fracture surgery at a Level 1 Trauma Center. Patients or their proxy (i.e., close relative) reported mobility, psychosocial, and functional outcomes at least 1-year after surgery. Results: Thirty-seven predominantly female (76%) patients with a median age of 85 years (IQR 79-92), and a median FI-CGA of 0.48 (IQR 0.43-0.54) were included. Eleven patients (30%) regained pre-fracture levels of ambulation, with twenty-six patients (70%) able to walk with or without assistance. The majority of patients (76%) were able to have meaningful conversations. Of the patients, 54% of them experienced no to minimal pain, while 8% still experienced a lot of pain. Functional independence varied, as follows: five patients (14%) could bathe themselves; nine patients (25%) could dress themselves; fourteen patients (39%) could toilet independently; and seventeen patients (47%) transferred out of a (wheel)chair independently. Conclusions: Despite the high risk of mortality and perioperative complications, many of the most severely frail patients with surgically treated femur fractures regain the ability to ambulate and live with a moderate degree of independence. This information can help healthcare providers to better inform these patients and their families of the role of surgical treatment during goals of care discussions.

Identifying Giant Cell Arteritis patients with higher risk of relapse and vascular events: a cluster analysis.

Giant cell arteritis (GCA) is one of the most common large vessel (LVV) vasculitis and is associated with a high risk of relapse and cardiovascular complications. Improving risk stratification remains a significant issue in this patient population. We aimed to perform a cluster analysis among GCA to identify clusters and evaluate their prognostic value. In a multicenter cohort study, we performed hierarchical cluster analysis on the factor analysis of mixed data coordinates results with 283 GCA patients' characteristics to generate clusters and assess incidence of relapse, cardiovascular events and death. Three clusters were identified: "Vascular relapsing profile" (23.0%), "Typical GCA profile" (47.7%), and "Ophthalmologic elderly profile" (29.3%). The "Vascular relapsing profile" cluster included younger patients with more frequent relapses and cardiovascular events, particularly thoracic aortic aneurysms. The "Typical GCA profile" was the largest, with classic cranial manifestations and frequently associated polymyalgia rheumatica. The "Ophthalmologic elderly profile" had the oldest patients with more visual loss and the highest mortality rate. Our findings underline the varied prognostic landscape within GCA, emphasizing the poor cardiovascular prognosis of younger patients with LV involvement and the higher mortality among elderly patients. This reinforces the need for further research regarding the screening of aortic abnormalities and whether those patients might benefit from intensive treatment with biotherapy and cardiovascular risk factors management.

Antiviral Use in Mild-to-Moderate SARS-CoV-2 Infections during the Omicron Wave in Geriatric Patients.

(1) Background: Geriatric patients are at high risk of complications of Coronavirus disease-2019 (COVID-19) and are good candidates for antiviral drugs. (2) Methods: A retrospective study of electronic health records (EHRs) aiming to describe antiviral (nirmatrelvir and ritonavir (nirmatrelvir/r) or remdesivir) use, drug-drug interactions (DDIs) and adverse drug reactions (ADRs) in elderly patients (75 and over), hospitalized with mild-to-moderate COVID-19 between July 2022 and June 2023. (3) Results: Out of 491 patients (mean age: 86.9 years), 180 (36.7%) received nirmatrelvir/r, 78 (15.9%) received remdesivir, and 233 (47.4%) received no antiviral therapy. No association was found between the choice of antiviral and the demographic or medical data. No serious ADR was observed. Nirmatrelvir/r dosage adjustment was inadequate in 65% of patients with renal impairment. In total, 128 patients (71%) on nirmatrelvir/r had potential pharmacokinetic DDIs, with 43 resulting in a possibly related ADR. In the remdesivir group, pharmacodynamic DDIs were more frequent, with QTc prolongation risk in 56 patients (72%). Only 20 patients underwent follow-up ECG, revealing QTc prolongation in 4. (4) Conclusions: There is an underutilization of antivirals despite their justified indications. Nirmatrelvir/r dosage was rarely adjusted to renal function. Dose adjustments and closer monitoring are needed due to the high risk of drug interactions.

Permanent epicardial pacing : a first line strategy in children

Abstract Background Permanent cardiac pacing in paediatric patients remains a challenge. According to the European Paediatric and Congenital Society (AEPC) recommendations, below 20 kg epicardial implantation is preferred, while above 20 kg endocardial implantation is given priority unless specific contraindication. In the literature, a weight at 15 kg is also found to be the minimal weight above which an endovascular implantation is considered. However, endovascular systems have been reported to be associated with a high risk of complications. Recent improvements in epicardial leads technology have significantly improved pacing thresholds (1-3), battery life and reduced the risk of re-intervention for epicardial lead dysfunction (4,5). Purpose The aim of the study is to evaluate the long-term results and efficacy of epicardial pacing in children and to investigate risk factors for epicardial lead dysfunction. Method We performed a retrospective, single-centre analysis of consecutive patients aged ˂18 years implanted with an epicardial PM between 2004 and 2020. The data collection included initial pacing parameters, at 1 month, 1 year, 2 years, and at last follow-up, as well as occurrence of early and late complications. Results A total of 101 patients (93 atrial and 131 ventricular epicardial) were analysed. The mean follow-up time was 6.2 years (range 2 days to 16.9 years). Median age at implantation was 4.2 years (IQ 0.3-8.8 years), median weight was 15.2 kg (IQ 5.2-28.0 kg). Congenital heart disease (CHD) was recorded in 59,4% of patients. Reasons for implantation were postoperative complete atrioventricular block (AVB) (40.6%), congenital AVB (37.6%), sinus dysfunction (7.9%), complete AVB with heart disease without surgery (7.9%), others (4%). Four patients had a system infection resulting in device extraction and reimplantation. The mortality rate was 15.8%, but no deaths was directly related to PM implantation or dysfunction. Detection values, impedances were stable over time, and the and average pacing thresholds remained ˂0,98±0,81 volt in the atrium and ˂ 1.57±0,89 volt in the ventricle. Lead survival was 96,7%, 90,7%, 82,3%, 74,5% at 1, 5, 8 and 10 years. The presence of CHD, weight ˂15kg, dual chamber implantation, implantation for postoperative BAV were not significant risk factors for lead dysfunction. In the group of patients implanted above 15kg the presence of a CHD significantly increased the risk of lead dysfunction (p=0.037) and all-cause reimplantation (p=0.010). In the group implanted above 15kg without any cardiopathy, the survival rate without lead dysfunction at 5 and 10 years was 100% and 90.9% respectively. Conclusion Epicardial pacing in children with steroid-eluting leads shows good long-term results with stable pacing parameters and good survival from lead dysfunction. For children implanted at a weight above 15 kg and without cardiopathy results with epicardial stimulation were excellent.Epicardial lead survival
