Factors influencing circuit lifetime in paediatric continuous kidney replacement therapies - results from the EurAKId registry.

Continuous kidney replacement therapy (CKRT) has recently become the preferred kidney replacement modality for children with acute kidney injury (AKI). We hypothesise that CKRT technical parameters and treatment settings in addition to the clinical characteristics of patients may influence the circuit lifetime in children. The study involved children included in the EurAKId registry (NCT02960867), who underwent CKRT treatment. We analysed patient characteristics and CKRT parameters. The primary end point was mean circuit lifetime (MCL). Secondary end points were number of elective circuit changes and occurrence of dialysis-related complications. The analysis was composed of 247 children who underwent 37,562h of CKRT (median 78, IQR 37-165h per patient). A total of 1357 circuits were utilised (3, IQR 2-6 per patient). MCL was longer in regional citrate anticoagulation (RCA), compared to heparin (HA) and no anticoagulation (NA) (42, IQR 32-58h; 24, IQR 14-34h; 18, IQR 12-24h, respectively, p < 0.001). RCA was associated with longer MCL regardless of the patient's age or dialyser surface. In multivariate analysis, MCL correlated with dialyser surface area (beta = 0.14, p = 0.016), left internal jugular vein vascular access site (beta = -0.37, p = 0.027), and the use of HA (beta = -0.14, p = 0.038) or NA (beta = -0.37, p < 0.001) vs. RCA. RCA was associated with the highest ratio of elective circuit changes and the lowest incidence of complications. Anticoagulation modality, dialyser surface, and vascular access site influence MCL. RCA should be considered when choosing first-line anticoagulation for CKRT in children. Further efforts should focus on developing guidelines and clinical practice recommendations for paediatric CKRT.

Breaking the cycle: Exploring the relationship of metacognition beliefs, obsessive-compulsive symptoms, and psychosocial performance among individuals diagnosed with schizophrenia.

This research paper explores the intricate relationship between metacognitive dysfunctional beliefs, obsessive-compulsive symptoms, and psychosocial performance in patients diagnosed with schizophrenia. Understanding these dynamics can help mental health nurses identify and address each patient's needs more effectively. It can guide them in devising personalized care plans that not only manage the symptoms but also improve the underlying mechanism that exacerbates the psychotic symptoms and social functioning and the overall quality of life. Moreover, the findings of this research can contribute to developing training programs for mental health nurses, equipping them with the necessary skills and knowledge to provide optimal care. What the paper adds to existing knowledge? • This study provides empirical evidence of the significant positive correlation between OCS and metacognitive dimensions in individuals with schizophrenia. • It highlights the role of certain demographic factors, such as younger age and single marital status, in increasing the likelihood of elevated OCS. • It underscores the inverse relationship between higher metacognitive dysfunctional beliefs and lower levels of psychosocial functioning. • It identifies age and metacognitive scores as crucial predictors of psychosocial functioning across various domains. What are the implications for practice? • The findings suggest that therapeutic nursing interventions for individuals diagnosed with schizophrenia should address metacognitive dysfunctional beliefs to improve overall functioning and well-being. • Clinicians, including psychiatrists and psychiatric nurses, should consider the patient's age, marital status, and metacognitive scores when assessing the risk of elevated OCS and devising treatment plans. • The study emphasizes the need for comprehensive psychiatric nursing assessment, including metacognitive dysfunction and OCS evaluation. What are the implications for future research? • Future research could explore the causal relationships between metacognitive dysfunctional beliefs, OCS, and psychosocial functioning in schizophrenia. • Longitudinal studies could provide insights into the progression of these relationships over time and the impact of therapeutic interventions. • Further research could also investigate the effectiveness of specific therapeutic strategies such as Metacognitive Therapy (MCT), Schema Therapy (ST), Cognitive Enhancement Therapy (CET), and Cognitive Behaviour Therapy (CBT) to address this population's metacognitive dysfunctional beliefs. BACKGROUND: Schizophrenia is a chronic mental health disorder that significantly impacts an individual's cognitive, emotional and social functioning. Recent research has highlighted the role of metacognitive beliefs and obsessive-compulsive symptoms (OCS) in the psychosocial performance of individuals diagnosed with schizophrenia. Understanding these relationships could provide valuable insights for developing more effective nursing interventions. This study aimed to investigate the relationship between metacognitive beliefs, OCS and psychosocial performance among individuals diagnosed with schizophrenia. A cross-sectional survey was conducted involving 174 purposively selected participants diagnosed with schizophrenia. The Meta-Cognitions Questionnaire-30, Young Adult Self-Report Scale for OCS and Specific Level of Functioning Scale were used to gather the necessary data. The study found a significant positive correlation between OCS and metacognitive dimensions. Age was a significant predictor with an Oddis Ratio of 2.471. The metacognitive dysfunction was a highly significant predictor in univariate and multivariate analyses, with Oddis Ratios of 1.087 and 1.106, respectively. The study also discovered that higher levels of metacognitive dysfunctional beliefs were associated with lower levels of psychosocial functioning. Age and the metacognitive dysfunction score were significant predictors of psychosocial functioning scores, accounting for 26.8% of the variance in these scores. The study reveals a compelling inverse relationship between higher metacognitive dysfunctional beliefs and lower levels of psychosocial functioning in individuals diagnosed with schizophrenia. It also identifies certain demographic factors, such as younger age, as significant contributors to elevated OCS. Importantly, metacognitive dysfunction emerged as a critical predictor of psychosocial functioning across various domains. These findings underscore the potential of incorporating metacognitive-focused interventions in the treatment plans for schizophrenia patients. By addressing these cognitive patterns, healthcare professionals can enhance overall functioning and well-being in individuals diagnosed with schizophrenia.

Prognostic role of nutritional and inflammatory indicators for patient survival and death with functional graft in living kidney transplant recipients.

The clinical importance of nutrition and inflammation in patients with end-stage renal disease is well established. In this study, we investigated the role of nutritional and inflammatory indicators in the patient outcomes of living donor kidney transplant recipients. We included 204 consecutive patients who underwent kidney transplantation at our institute between 2003 and 2022. We retrospectively reviewed medical charts to obtain clinical information. Six nutritional indicators and two inflammatory indicators were assessed. Patient outcomes were investigated, and predictive factors were explored. The median patient age and follow-up period were 48years and 99months, respectively. The cohort included patients with preoperative malnutrition and microinflammation. No significant differences in graft survival were identified according to nutritional and inflammatory indicators, whereas the survival index, controlled nutritional status, and C-reactive protein levels were associated with patient survival. The survival index was an independent indicator of survival and death in patients with functioning grafts (P = 0.047 and P = 0.013, respectively). Furthermore, the C-reactive protein level could distinguish between low and high mortality risks in patients with good nutrition (P = 0.019). Our findings suggest that nutrition and inflammation indicators play important roles in predicting outcomes in living donor kidney transplantation recipients. Further research is warranted to establish optimal management strategies.

Clinical characteristics and outcomes after trigeminal schwannoma resection: a multi-institutional experience.

Given their rarity, the clinical course of patients undergoing trigeminal schwannoma (TS) resection remains understudied. The objective of this study is to describe clinical characteristics and outcomes in patients undergoing surgical resection for TS in a multi-institutional cohort. This is a retrospective study of patients undergoing TS resection at two institutions between 2004 and 2022. Patient, radiographic, and clinical characteristics were reviewed and analyzed with standard statistical methods. Thirty patients were included. The median patient age was 43 (IQR: 35-52) years, and 14 (47%) patients were female. Median clinical and radiographic follow-ups were 43 (IQR: 20-81) and 47 (IQR: 27-97) months respectively. The most common presenting symptoms were trigeminal hypesthesia (57%) and headaches (30%), diplopia (30%), and ataxia/cerebellar signs (30%). The median maximum tumor diameter was 3.3 (IQR: 2.5-5.4) cm. Most tumors were Samii type C (50%) and mixed cystic-solid (63%). Surgical approaches included endoscopic endonasal (33%), supratentorial (30%), combined/staged (20%), infratentorial (10%), and anterior petrosal (7%) approaches. Gross-total resection was achieved in 16 (53%) patients. Radiographic tumor recurrence was noted in four patients at a median of 79 (range 5-152) months. Twenty-six (87%) patients reported improvements in at least one symptom by last follow-up. The most common perioperative complication was new cranial nerve deficit, with 17% of patients having a transient deficit and 10% having a permanent cranial nerve deficit. Surgical resection of TS showed good progression-free survival and symptom improvement, but was associated with cranial nerve deficits.

PRADOC: A Multicenter Randomized Controlled Trial to Assess the Efficiency of PRADO-IC, a Nationwide Pragmatic Transition Care Management Plan for Hospitalized Patients With Heart Failure in France.

The PRADO-IC (Programme de Retour à Domicile après une Insuffisance Cardiaque) is a transition care program designed to improve the coordination of care between hospital and home that was generalized in France in 2014. The PRADO-IC consists of an administrative assistant who visits patients during hospitalization to schedule follow-up visits. The aim of the present study was to evaluate the PRADO-IC program based on the hypotheses provided by health authorities. The PRADOC study is a multicenter, controlled, randomized, open-label, mixed-method trial of the transition program PRADO-IC versus usual management in patients hospitalized with heart failure (standard of care group; NCT03396081). A total of 404 patients were recruited between April 2018 and May 2021. The mean patient age was 75 years (±12 years) in both groups. The 2 groups were well balanced regarding severity indices. At discharge, patients homogeneously received the recommended drugs. There was no difference between groups regarding hospitalizations for acute heart failure at 1 year, with 24.60% in the standard of care group and 25.40% in the PRADO-IC group during the year following the index hospitalization (hazard ratio, 1.04 [95% CI, 0.69-1.56]; P=0.85) or cardiovascular mortality (hazard ratio, 0.67 [95% CI, 0.34-1.31]; P=0.24). The PRADO-IC has not significantly improved clinical outcomes, though a trend toward reduced cardiovascular mortality is evident. These results will help in understanding how transitional care programs remain to be integrated in pathways of current patients, including telemonitoring, and to better tailor individualized approaches.

Undetected, natural conception pregnancies in luteal phase stimulations-case series and review of literature.

What is the risk of an undetected natural conception pregnancy during luteal phase ovarian stimulation, and how does it impact the pregnancy's course? The risk for an undetected, natural conception pregnancy in luteal phase ovarian stimulation is low and it appears that ovarian stimulation is unlikely to harm the pregnancy. Random start ovarian stimulation appears to be similarly effective as early follicular stimulation start; and it allows ovarian stimulation to be started independent of the cycle day and throughout the cycle, in accordance with the patients' and clinics' schedule as long as there is no intention of a fresh embryo transfer in the same cycle. Starting ovarian stimulation in the luteal phase bears the possibility of an-at the timepoint of stimulation start-undetected, natural conception pregnancy that has already occurred. There is scarce data on the incidence of this event as well as on the possible implications of ovarian stimulation on the course of an existing pregnancy. This retrospective observational study, performed between June 2017 and January 2024, analyzed luteal phase stimulations, in which a natural conception pregnancy was detected during the ovarian stimulation treatment for IVF/ICSI. Luteal phase stimulation was defined as ovarian stimulation started after ovulation and before the next expected menstrual bleeding, with a serum progesterone (P4) level of >1.5 ng/ml on the day of stimulation start or 1 day before. Women who underwent a luteal phase ovarian stimulation in a tertiary referral ART center. A total of 488 luteal phase stimulation cycles were included in the analysis. Luteal phase stimulation was only started after a negative serum hCG measurement on the day or 1 day before commencement of ovarian stimulation. Ten patients (2.1%) had an undetected natural conception pregnancy at the time of luteal phase stimulation start. Eight of these patients underwent an ovarian stimulation in a GnRH-antagonist protocol and two in a progestin-primed stimulation protocol (PPOS). Recombinant FSH was used as stimulation medication for all patients, the patients with a PPOS protocol received additional recombinant LH. One pregnancy (0.2%) was detected after the oocyte retrieval, the other nine pregnancies were detected either due to persistent high serum progesterone levels or due to an increasing progesterone level after an initial decrease before oocyte retrieval. In the cycles with an undetected natural conception pregnancy, the median number of stimulation days was 8 days (range: 6-11 days) and median serum hCG at detection of pregnancy was 59 IU hCG (range: 14.91-183.1). From 10 patients with a pregnancy, three patients delivered a healthy baby, two patients had ongoing pregnancies at the time of summarizing the data, three patients had biochemical pregnancies (patient age: 30, 39, and 42 years), one patient had an ectopic pregnancy which required a salpingectomy, and one patient (age: 34 years) had an early pregnancy loss. The retrospective study design and the small sample size can limit the accuracy of the estimates. Overall, there is a small risk of undetected natural conception pregnancies when luteal phase stimulation is undertaken. It appears that there are no adverse effects through either direct effect on the embryo or indirectly through a detrimental effect on the corpus luteum function on the pregnancy in our cohort. This study did not receive funding. The authors declare that there is no conflict of interest. N/A.

The epidemiology of odontoid fractures: a study from the Swedish fracture register.

The objective of this study is to characterize the occurrence of odontoid fractures within a Swedish population. Prospective data of adults diagnosed with an odontoid fracture between 2015 and 2021 were retrieved from the Swedish Fracture Register (SFR). Epidemiologic data including age, sex, injury mechanism, injury type, fracture type(Anderson and D'Alonzo classification), neurological status and treatment type were requested from the SFR. Data pertinent to osteoporosis was retrieved from the Swedish National Patient Register. A total of 1,154 odontoid fractures were identified, of which 30 were type I fractures, 583 type II fractures, and 541 type III fractures. The mean (Standard Deviation [SD]) age was 77.2 (13.8) years. The prevalence of osteoporosis and neurological deficits did not differ between the fracture types. The majority of patients were treated non-surgically (81%). Male sex and patient age 18-30 years were commonly associated with a high-injury mechanism, especially motor vehicle accidents. In the type II fracture group, significantly more patients had fallen from standing height or less than in the type III group (66% vs. 58%, p = 0.01) while in contrast, motor vehicle accidents were more common in the type III fracture group (12% vs. type II: 8%, p = 0.04). Based on the SFR, the typical odontoid fracture patient is older and suffers a type II fracture. Most injuries were caused by low-energy trauma although in younger patients and males, they were associated with motor vehicle accidents. Across the patient population, odontoid fractures were usually treated non-surgically.

Risk Factors for Replacement of Tympanostomy Tubes After Surgical Removal for Pediatric Patients.

Ear tube removal and patch myringoplasty are frequently performed. The indication and timing for surgery varies among otolaryngologists. This study identifies risk factors associated with the need for the replacement of tympanostomy tubes after tube removal and myringoplasty. Case series with chart review. Single institution academic otolaryngology practice. Patients younger than 12 years of age who underwent tympanostomy tube removal and myringoplasty at the University of Rochester Medical Center from March 2011 to September 2019. Patients with tympanostomy tube removal due to chronic otorrhea were excluded. One hundred sixty-one patients (230 ears) met inclusion criteria and had sufficient follow-up. Myringoplasty success after tube removal was 94.8%. Successful myringoplasty was associated with shorter tube duration (32 months) versus unsuccessful myringoplasty (40 months) (P = .02). Replacement tympanostomy tubes after myringoplasty occurred in 9.6% of ears. There was no difference in average patient age (P = .96) or duration of tubes (P = .74) in patients who required replacement of tympanostomy tubes versus patients who did not require tube replacement. Patients with a cleft abnormality were more likely to require tympanostomy tube replacement (P < .001). Most children do not need tubes replaced after removal. This study identified cleft abnormality as a factor that increased the need for replacement tubes. Longer tube durations of over 3 years negatively impacted myringoplasty success. Tympanostomy tube removal should be considered 2 to 3 years after placement in most patients with longer tube durations considered in children with a repaired cleft palate.

Post-Transplant Cyclophosphamide-Based Graft-Versus-Host Disease Prophylaxis Attenuates Disparity in Outcomes Between Use of Matched or Mismatched Unrelated Donors.

Access to allogeneic hematopoietic cell transplantation (HCT) remains limited among persons of non-European ancestry if human leukocyte antigen (HLA) matching is required. We evaluated whether post-transplant cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis improved HCT outcomes with HLA-matched unrelated donor (MUD) and mismatched unrelated donor (MMUD) HCT when compared with calcineurin inhibitor (CNI)-based prophylaxis. Three-year overall survival (OS) and GVHD-free, relapse-free survival (GRFS) were compared between adult recipients undergoing initial MUD or single HLA locus MMUD HCT with either PTCy- or CNI-based prophylaxis who were reported to the Center for International Blood and Marrow Transplant Research between 2017 and 2021. Included were 10,025 HCT recipients (7,272 recipients of MUD with CNI, 1,681 MUD with PTCy, 613 MMUD with CNI, and 459 MMUD with PTCy) who underwent HCT for acute leukemia (70.9%) or myelodysplastic syndromes (29.2%). Median patient age was 60.7 years (range, 18.0-82.7) and median follow-up was 36.6 (range, 3.0-77.8) months. When compared with MUD HCT with PTCy, MMUD HCT with PTCy had similar OS (hazard ratio [HR], 0.96 [95% CI, 0.823 to 1.11]; P = .60) and GRFS (HR, 0.90 [0.79 to 1.02]; P = .1). When compared with MUD HCT with CNI, OS was improved after MUD HCT with PTCy (HR, 0.88 [0.80 to 0.96]; P = .004) and GRFS was improved with PTCy after either MUD (HR, 0.61 [0.57 to 0.66]; P < .0001) or MMUD (HR, 0.68 [0.60 to 0.76]; P < .0001) HCT. Benefit from PTCy was independent of patient ancestry. Global registry level analysis demonstrated that inclusion of MMUD increased donor availability regardless of recipient ancestry. Use of PTCy results in comparable OS and GRFS using either MUD or MMUD HCT, expanding access to HCT for patients from all racial and ethnic ancestry groups.

Optimization of treatment strategies for elderly patients with advanced non-small cell lung cancer

Lung cancer stands as a malignant neoplasm bearing the highest burden of morbidity and mortality within the elderly population on a global scale. Among the lung cancer subtypes, non-small cell lung cancer (NSCLC) prevails as the most prevalent. As age advances, elderly patients often present with an increased prevalence of comorbidities, diminished organ reserve function, and alterations in drug pharmacokinetics, including absorption, distribution, metabolism, and clearance. These factors collectively contribute to a reduction in their capacity to tolerate therapeutic interventions. Regrettably, there exists a paucity of research data and evidence regarding the management of elderly patients afflicted by advanced lung cancer. This article endeavors to compile and elucidate strategies for the enhancement of treatment approaches, with the aim of aiding clinical decision-making. Prior to the selection of clinical treatment modalities for elderly patients with advanced NSCLC, a comprehensive assessment should be conducted, taking into account various facets, including tumor characteristics, patient age, physiological status, and the presence of comorbidities. The treatment strategy should be implemented in a tiered fashion, thereby affording the opportunity for the tailoring of individualized therapeutic approaches for elderly patients afflicted by advanced NSCLC. The demographic of elderly patients confronting advanced NSCLC presents a complex landscape marked by intricate underlying conditions, necessitating the imperative optimization of treatment strategies.

Long-term penile prosthesis couple's satisfaction: A systematic review and meta-analysis.

Data supporting successful and satisfactory penile prosthesis (PP) implantation outcomes are mainly based on subjective, rather than objective, analysis. To systematically review and objectively analyze, all available data related to patient and partner PP satisfaction. An extensive search was performed, including the following key-words: ("penile prosthesis" and "satisfaction"). The search, which accrued data from January 1, 1969, up to July 31, 2023, was restricted to English-language articles including human participants. Out of 663 retrieved articles, 83 were considered including, 12,132 subjects with a mean age and mean follow-up of 58.6 [range 20; 77.1] years and 47.6 [range 6; 374] months, respectively. Overall, a high patient satisfaction rate was observed 83[80; 86]%. The satisfaction rate increased in subjects with three-piece PP and in those with a higher rate of cardiovascular or neurological diseases and was independent of the patient's age. Partner's satisfaction rate was lower when compared to that observed in men and it increased according to the use of inflatable devices and the presence of patient Peyronie's disease. The long-term complication rate was limited ranging from 3% for erosion to 4.6% when mechanical failure was considered. Patient and partner satisfaction is excellent and increases with time. The number of complications is limited and is strongly associated with the presence of diabetes mellitus. We found a high couple satisfaction score that was higher when reported by males compared to females. Patient satisfaction increased with time, and it was independent of age.

Predictors of In-Hospital Mortality after Thrombectomy in Anterior Circulation Large Vessel Occlusion: A Retrospective, Machine Learning Study

Background: Despite the increased use of mechanical thrombectomy (MT) in recent years, there remains a lack of research on in-hospital mortality rates following the procedure, the primary factors influencing these rates, and the potential for predicting them. This study aimed to utilize interpretable machine learning (ML) to help clarify these uncertainties. Methods: This retrospective study involved patients with anterior circulation large vessel occlusion (LVO)-related ischemic stroke who underwent MT. The patient division was made into two groups: (I) the in-hospital death group, referred to as miserable outcome, and (II) the in-hospital survival group, or favorable outcome. Python 3.10.9 was utilized to develop the machine learning models, which consisted of two types based on input features: (I) the Pre-MT model, incorporating baseline features, and (II) the Post-MT model, which included both baseline and MT-related features. After a feature selection process, the models were trained, internally evaluated, and tested, after which interpretation frameworks were employed to clarify the decision-making processes. Results: This study included 602 patients with a median age of 76 years (interquartile range (IQR) 65–83), out of which 54% (n = 328) were female, and 22% (n = 133) had miserable outcomes. Selected baseline features were age, baseline National Institutes of Health Stroke Scale (NIHSS) value, neutrophil-to-lymphocyte ratio (NLR), international normalized ratio (INR), the type of the affected vessel (‘Vessel type’), peripheral arterial disease (PAD), baseline glycemia, and premorbid modified Rankin scale (pre-mRS). The highest odds ratio of 4.504 was observed with the presence of peripheral arterial disease (95% confidence interval (CI), 2.120–9.569). The Pre-MT model achieved an area under the curve (AUC) value of around 79% utilizing these features, and the interpretable framework discovered the baseline NIHSS value as the most influential factor. In the second data set, selected features were the same, excluding pre-mRS and including puncture-to-procedure-end time (PET) and onset-to-puncture time (OPT). The AUC value of the Post-MT model was around 84% with age being the highest-ranked feature. Conclusions: This study demonstrates the moderate to strong effectiveness of interpretable machine learning models in predicting in-hospital mortality following mechanical thrombectomy for ischemic stroke, with AUCs of 0.792 for the Pre-MT model and 0.837 for the Post-MT model. Key predictors included patient age, baseline NIHSS, NLR, INR, occluded vessel type, PAD, baseline glycemia, pre-mRS, PET, and OPT. These findings provide valuable insights into risk factors and could improve post-procedural patient management.

Sedation reversal trends at outpatient ambulatory endoscopic center vs in-hospital ambulatory procedure center using a triage protocol

BACKGROUND Routine outpatient endoscopy is performed across a variety of outpatient settings. A known risk of performing endoscopy under moderate sedation is the potential for over-sedation, requiring the use of reversal agents. More needs to be reported on rates of reversal across different outpatient settings. Our academic tertiary care center utilizes a triage tool that directs higher-risk patients to the in-hospital ambulatory procedure center (APC) for their procedure. Here, we report data on outpatient sedation reversal rates for endoscopy performed at an in-hospital APC vs at a free-standing ambulatory endoscopy digestive health center (AEC-DHC) following risk stratification with a triage tool. AIM To observe the effect of risk stratification using a triage tool on patient outcomes, primarily sedation reversal events. METHODS We observed all outpatient endoscopy procedures performed at AEC-DHC and APC from April 2013 to September 2019. Procedures were stratified to their respective sites using a triage tool. We evaluated each procedure for which sedation reversal with flumazenil and naloxone was recorded. Demographics and characteristics recorded include patient age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, procedure type, and reason for sedation reversal. RESULTS There were 97366 endoscopic procedures performed at AEC-DHC and 22494 at the APC during the study period. Of these, 17 patients at AEC-DHC and 9 at the APC underwent sedation reversals (0.017% vs 0.04%; P = 0.06). Demographics recorded for those requiring reversal at AEC-DHC vs APC included mean age (53.5 ± 21 vs 60.4 ± 17.42 years; P = 0.23), ASA class (1.66 ± 0.48 vs 2.22 ± 0.83; P = 0.20), BMI (27.7 ± 6.7 kg/m2 vs 23.7 ± 4.03 kg/m2; P = 0.06), and female gender (64.7% vs 22%; P = 0.04). The mean doses of sedative agents and reversal drugs used at AEC-DHC vs APC were midazolam (5.9 ± 1.7 mg vs 8.9 ± 3.5 mg; P = 0.01), fentanyl (147.1 ± 49.9 μg vs 188.9 ± 74.1 μg; P = 0.10), flumazenil (0.3 ± 0.18 μg vs 0.17 ± 0.17 μg; P = 0.13) and naloxone (0.32 ± 0.10 mg vs 0.28 ± 0.12 mg; P = 0.35). Procedures at AEC-DHC requiring sedation reversal included colonoscopies (n = 6), esophagogastroduodenoscopy (EGD) (n = 9) and EGD/colonoscopies (n = 2), whereas APC procedures included EGDs (n = 2), EGD with gastrostomy tube placement (n = 1), endoscopic retrograde cholangiopancreatography (n = 2) and endoscopic ultrasound's (n = 4). The indications for sedation reversal at AEC-DHC included hypoxia (n = 13; 76%), excessive somnolence (n = 3; 18%), and hypotension (n = 1; 6%), whereas, at APC, these included hypoxia (n = 7; 78%) and hypotension (n = 2; 22%). No sedation-related deaths or long-term post-sedation reversal adverse outcomes occurred at either site. CONCLUSION Our study highlights the effectiveness of a triage tool used at our tertiary care hospital for risk stratification in minimizing sedation reversal events during outpatient endoscopy procedures. Using a triage tool for risk stratification, low rates of sedation reversal can be achieved in the ambulatory settings for EGD and colonoscopy.

Identification of prognostic imaging biomarkers in H3 K27-altered diffuse midline gliomas in adults: impact of tumor oxygenation imaging biomarkers on survival.

To investigate prognostic markers for H3 K27-altered diffuse midline gliomas (DMGs) in adults with clinical, qualitative and quantitative imaging phenotypes, including tumor oxygenation characteristics. Retrospective chart and imaging reviews were conducted on 32 adults with H3 K27-altered DMGs between 2017 and 2023. Clinical and qualitative imaging characteristics were analyzed. Quantitative imaging assessment was performed from the tumor mask via automatic segmentation to calculate normalized cerebral blood volume (nCBV), capillary transit time heterogeneity (CTH), oxygen extraction fraction (OEF), relative cerebral metabolic rate of oxygen (rCMRO2), and mean ADC values. Leptomeningeal metastases (LM) was diagnosed with imaging. Cox analyses were conducted to determine predictors of overall survival (OS) in entire patients and a subgroup of patients with contrast-enhancing (CE) tumor. The median patient age was 40.5 years (range 19.9-75.7), with an OS of 30.3 months (interquartile range 11.3-32.3). In entire patients, the presence of LM was the only independent predictor of OS (hazard ratio [HR] = 6.01, P = 0.009). In the subgroup of 23 (71.9%) patients with CE tumors, rCMRO2 of CE tumor (HR = 1.08, P = 0.019) and the presence of LM (HR = 5.92, P = 0.043) were independent predictors of OS. The presence of LM was independently associated with poor prognosis in adult patients with H3 K27-altered DMG. In patients with CE tumors, higher rCMRO2 of CE tumor, which may reflect higher metabolic activity in the tumor oxygenation microenvironment, may be a useful imaging biomarker to predict poor prognosis.

When Perfect Is the Enemy of Good: Results of a RAND Appropriateness Panel on Treat to Target in Asymptomatic IBD.

A treat-to-target strategy for inflammatory bowel disease (IBD) recommends iterative treatment adjustments to achieve clinical and endoscopic remission. In asymptomatic patients with ongoing endoscopic activity, the risk/benefit balance of this approach is unclear, particularly with prior exposure to advanced therapies. Using the RAND/UCLA Appropriateness Method, 9 IBD specialists rated appropriateness of changing therapy in 126 scenarios of asymptomatic patients with ulcerative colitis (UC) and Crohn's disease (CD) and active endoscopic disease. Disease extent and behavior, prior treatment, prior complications, and recent disease progression were considered, as were factors that might influence decision-making, including age and pregnancy. Ratings were collected via anonymous survey, discussed at an in-person meeting, and finalized in a second anonymous survey. Panelists rated change in therapy as appropriate (i.e., expected benefit sufficiently outweighs potential harms from continuing therapy) in 96/126 scenarios, generally in patients with progressive, complicated, and/or extensive disease, while changing therapy was rated uncertain in 27 scenarios of mild and/or stable disease. Changing therapy was rated inappropriate in UC patients with mild and stable disease previously exposed to ≥3 therapies or with improved endoscopic activity, and in CD patients with only scattered aphthous ulcers. The validated threshold for disagreement was not crossed for any scenario. Patient age >65 years and a plan for pregnancy in the next year might influence decision-making in some settings. Appropriateness ratings can help guide clinical decision-making about changing therapy to achieve endoscopic remission in asymptomatic patients with IBD until data from ongoing randomized studies are available.

Orthodontic and Surgical Management of Impacted Maxillary Canines: A Narrative Review

AbstractMaxillary canine impactions are a significant challenge for orthodontic and oral surgical practices. In this narrative review, we aim to evaluate surgical and orthodontic approaches for treating maxillary canine impactions, evaluate their effectiveness, and compare the two treatment modalities.We reviewed several studies on databases such as Google Scholar, PUBMED, and MEDLINE to update recent knowledge for canine impactions and their treatment. We reviewed and included studies that matched our research objectives, including orthodontic management, open and closed eruption techniques, and contact and tooth alignment surgery.Successful treatment results of canine impactions were reported increasingly in literature, and good clinical outcomes were observed in most cases. However, factors such as the severity of the impaction, patient age, and surgical experience were found to influence the choice of surgical technique and success rates. Complications associated with surgical management of maxillary canine impactions were also reported. These complications, which include tooth resorption, postoperative infection, ankylosis, and damage to adjacent structures, are generally rare but emphasize the importance of careful patient selection, surgical planning accuracy, and emphasis on diligent postoperative care.Findings highlight surgical procedures' effectiveness, outcomes, and challenges to help clinicians make informed decisions and improve patient care. The results underscore the importance of evidence-based decision-making and a multidisciplinary approach for successful clinical outcomes. Future research will focus on long-term stability, patient-reported outcomes, and exploring emerging techniques to further improve the management of maxillary canine impactions.

Simultaneous correction of leg length discrepancy and angular deformity of the distal femur with retrograde Precice nails: a retrospective analysis of 45 patients.

Magnetically controlled motorized intramedullary lengthening nails (ILNs) can be employed for simultaneous correction of angular deformities of the distal femur and leg length discrepancy. This spares typical complications of external fixators but requires precise preoperative planning and exact intraoperative execution. To date, its results are insufficiently reported. We aimed to elucidate the following questions: (i) Is acute angular deformity correction and gradual femoral lengthening via a retrograde ILN a reliable and precise treatment option? (ii) What are the most common complications of treatment? Acute angular deformity correction and subsequent gradual lengthening of the distal femur with retrograde ILN was retrospectively analyzed in 45 patients (median patient age: 15 years, interquartile range [IQR] 13-19 and median follow-up: 40 months, IQR 31-50). Outcome parameters were accuracy, precision, reliability, bone healing, and complications of treatment. The median distraction was 46 mm (IQR 29-49), median distraction and consolidation index 0.9 mm/day (IQR 0.7-1.0) and 29 days/cm (IQR 24-43), respectively. The median preoperative mechanical axis deviation (MAD) was 30 mm (IQR 23-39) in the varus cohort and -25 mm (IQR -29 to -15) in the valgus cohort and reduced to a mean of 8 mm (standard deviation [SD] 8) and -3 (SD 10), respectively. Accuracy, precision, and reliability of lengthening were 94%, 95% and 96%, respectively. Accuracy and precision of deformity correction were 92% and 89%, respectively. In total, 40/45 of patients achieved distraction with a difference of less than 1 cm from the initial plan and a postoperative MAD ranging from -10 mm to +15 mm. In 13/45 patients unplanned additional surgeries were conducted to achieve treatment goal with nonunion being the most frequent (4/45) and knee subluxation (3/45) the most severe complication. Acute deformity correction and subsequent lengthening of the distal femur with retrograde ILN is a reliable and accurate treatment achieving treatment goal in 89% but unplanned additional surgeries in 29% of patients should be anticipated.

Molecular analysis of persistent and recurrent Barrett's esophagus in the setting of endoscopic therapy.

Early neoplastic progression of Barrett's esophagus (BE) is often treated with endoscopic therapy. While effective, some patients are refractory to therapy or recur after apparent eradication of the BE. The goal of this study was to determine whether genomic alterations within the treated BE may be associated with persistent or recurrent disease. We performed DNA sequencing on pre-treatment esophageal samples from 45 patients who were successfully treated by endoscopic therapy and did not recur as well as pre- and post-treatment samples from 40 patients who had persistent neoplasia and 21 patients who had recurrent neoplasia. The genomic alterations were compared between groups. The genomic landscape was similar between all groups. Patients with persistent disease were more likely to have pre-treatment alterations involving the receptor tyrosine kinase pathway (p=0.01), amplifications of oncogenes (p=0.01), and deletions of tumor suppressor genes (p=0.02). These associations were no longer significant after adjusting for patient age and BE length. Over half of patients with persistent (52.5%) or recurrent (57.2%) disease showed pre- and post-treatment samples that shared at least 50% of their driver mutations. Pre-treatment samples were genomically similar between those who responded to endoscopic therapy and those who had persistent or recurrent disease, suggesting there is not a strong genomic component to treatment response. While it was expected to find shared driver mutations in pre- and post-treatment samples in patients with persistent disease, the finding that an equal number of patients with recurrent disease also showed this relation suggests that many recurrences represent undetected minimal residual disease.

Acute toxicity of chemotherapy in central nervous system germ cell tumour patients according to age

BackgroundSIOP-CNS-GCT-II European trial was opened for the treatment of patients of any age with central nervous system germ cell tumour (CNS-GCT). Four courses of pre-irradiation chemotherapy were delivered. The influence of patient age on chemotherapy related acute toxicity (CRAT) was assessed.MethodsCRAT was analysed according to age-groups: children (aged ≤11 years), adolescents (aged 12-17 years), adults (aged ≥18 years) and to chemotherapy type: CarboPEI (alternating etoposide-carboplatin/etoposide-ifosfamide) for non-metastatic germinoma; PEI (cisplatin-etoposide-ifosfamide) for standard-risk non-germinomatous GCT (NGGCT); PEI and high-dose PEI (HD-PEI), for high-risk or poorly responsive NGGCTs.Results296 patients were assessable for CRAT: 105 children, 121 adolescents, 70 adults (max age: 41 years). Median cumulative doses/m² of chemotherapy were similar among age-groups. The proportion of germinoma over NGGCT (and accordingly use of CarboPEI chemotherapy) was higher in the adult groups (79%) versus the other two groups (62%). Delay in chemotherapy ≥7 days was noticed in 27%, 38%, and 19% of children, adolescents, and adults, respectively. Grade ≥3 haematological and non-haematological adverse events (AEs) were observed in 94%/31%, 97%/36%, and 77%/21% of children, adolescents, and adults, respectively. No toxic death was reported. Grade ≥3 AEs and delayed chemotherapies were significantly rarer in adults when compared with adolescents, even when adjusted on chemotherapy type: odds ratio: 0.1 [95%CI 0.02-0.4], and 0.2 [95%CI 0.1-0.4] in the group treated with CarboPEI.ConclusionAdult patients can be treated safely with a chemotherapy intensive protocol, with even less toxicity than that observed in adolescents. Further work is required to understand age-related differences regarding toxicity.

Clinical characteristics and factors associated with survival rate of patients with non-muscle invasive bladder cancer attending at a Tertiary Hospital in Somalia

BackgroundA few studies regarding the epidemiology and risk factors of Non-muscle Invasive Bladder Cancer (NMIBC) are reported from Sub-Saharan African countries (SSA), including Somalia, and the African literature is scant on the management of NMIBC. The present study aims to evaluate the clinical-histopathological characteristics and factors associated with the survival rate of patients with NMIBC.MethodThis six-year cohort study included 196 patients with NMIBC. It reviewed the clinical and histopathological characteristics and factors predicting cancer-specific survival for these patients.ResultsThe mean patient age was 59.01 ± 11.50 years, with a male-to-female ratio of 2.8:1. Urothelial carcinoma (UC) constituted the most common pathological type, accounting for 90.8%; Ta LG and T1HG were the most common histopathological tumour stage and grade (n = 90, 45.9%, vs. n = 56, 28.6%), respectively. The mean tumour size was 4.72 ± 2.81 cm. The cancer-specific mortality(CSM) was 13.3%. Age [2.252(2.310–2.943], p < 0.001], Gender [1.031(0.981-1.1.242),p < 0.001], tumour stage and grade [4.902(3.607–5.614),p < 0.001], tumour location [1.135(0.806–1.172),p < 0.001], number [0.510(0.410–0.920),p = 0.03], tumour size [1.523(0.936–1.541),p < 0.001], use of intravesical chemotherapy or BCG [2.810(1.972–4.381),p < 0.001], preoperative hydronephrosis grade [1.517(1.172–2.154),p < 0.001], and follow-up compliance [3.376(2.633–5.018),p < 0.001] were all associated with CSM. The 5-year overall survival was 57.1%, and cardiovascular diseases were the leading cause of mortality (n = 34), followed by diabetes (n = 28).ConclusionOur study findings revealed that UC constituted the most common pathological subtype, though less than forty per cent of our patients receive intravesical adjuvant therapies, which are crucial to minimizing disease morbidity and mortality. Initiatives improving uro-oncological care, including subspecialty training in oncology and essential cancer therapies, better access to urology services, and cancer screening programs, are much needed for optimal management plans and care in the country.
