This study aimed to describe the area under the plasma concentration-time curve (AUC) and the relationship with hematological toxicity plus clinical responses of docetaxel in patients with nasopharyngeal carcinoma. Furthermore, a suitable docetaxel exposure level would be identified to guide clinical dosing.

96 patients with locally advanced or metastatic nasopharyngeal carcinoma treated with docetaxel-based chemotherapy were enrolled. Docetaxel was measured by turbidimetric immunoassay. Associations between docetaxel exposure and hematologic toxicity, effect, and recurrence time were analyzed. Receiver operating characteristic curve analysis was performed to determine an optimal AUC value to predict the decrease in absolute neutrophil counts.

Interpatient variability was large with regard to exposure (AUC) and clearance. The AUC values of 76 patients in course 1 varied more than 4 fold (3.17±0.84 µg×h/mL, ranging from 1.4 to 6.0 µg×h/mL). Clearance was 42.8L/h (ranging from 20.8 to 73.7L/h) with ~3-fold interindividual variability. The incidence of grade 3/4 leukopenia, 3/4 neutropenia, and febrile neutropenia was 46.3, 85.2, and 13.5%, respectively, in course 1. Docetaxel exposure was the only significant predictor (p<0.001) of severe toxicity, including grade 4 neutropenia and febrile neutropenia. A cutoff value of 2.85 µg×h/mL was selected as the target AUC. Higher AUC values were not observed to be associated with better drug effect.

The dose was calculated based on individual clearance and a target AUC of 2.85 µg×h/mL, helping to adjust the next cycle of doses and solve interpatient variability.

Limited evidence is available regarding the effectiveness of a specialized continuous renal replacement therapy (CRRT) team approach. Hence, we aimed to evaluate the effectiveness of a specialized CRRT team intervention in a Japanese hospital.

We retrospectively identified adult patients who underwent CRRT in the intensive care unit (ICU) from July 2015 to June 2019 and divided them into two groups based on whether or not they received CRRT team intervention. We extracted data from the electronic medical record database. The concurrent effects of various factors on study outcomes were analyzed by multivariate analysis using a generalized linear model.

A total of 540 patients were included. Baseline characteristics were similar in the two groups. In univariate analysis, no significant differences were found in in-hospital mortality (34.0 vs. 30.8%; risk difference, -3.2%; 95% confidence interval, -12.6 to 6.1), total duration of ICU stay, total CRRT time, and the proportion of patients starting maintenance hemodialysis during hospitalization between both groups. Multivariate analysis also indicated no significant differences.

In this study, no significant difference was found in patient outcomes between both groups. The results suggest that the CRRT team should have integrated protocols and play a core role in CRRT management.

Infection-related glomerulonephritis (IRGN) is an example of immune-mediated glomerular injury, with changing profile over the years. We analyzed the clinicopathological profile of IRGN from a single center.

Adult renal biopsies between July 2018 and January 2020 were screened, and biopsies with IRGN were included. The demographic, clinical, and laboratory data up to 6 months were analyzed.

27 patients were included, with 63% having evidence of current/recent infection,
and
being most common (29.4%). The mean eGFR at presentation was 16.7mL/min/1.73m
, with crescents in 70.4% of cases. 59.3% required dialysis, and 40.7% received steroids. Complete recovery was seen in 84.6%, while 11.1% developed chronic kidney disease, and 3.7% progressed to end-stage renal disease. Persistent proteinuria, hematuria, and hypertension at 6 months were seen in 11.1, 7.4, and 3.7%, respectively. There was significant negative correlation between renal recovery and history of diabetes, interstitial fibrosis and tubular atrophy (IFTA), glomerulosclerosis, and IgA deposits. There was no significant impact of steroid use on outcome.

IRGN can have an aggressive course in adults, with renal recovery continuing beyond 3 months. IFTA, glomerulosclerosis, IgA deposits, and history of DM are significant negative predictors of clinical outcome, and there is no proven benefit of steroids.

While the true incidence is likely underestimated, less than 500 cases of TIO have been reported since initial description in 1947. TIO cases have classically been associated with mesenchymal tumors of bone and soft tissue, but have also rarely been linked to malignant tumors, with scant reports implicating non-mesenchymal tumors. TIO is mediated through inappropriate tumor overproduction of fibroblast growth factor 23 (FGF23). Increased FGF23 secretion leads to hypophosphatemia by (1) reduced phosphate reabsorption via activation of the proximal renal tubular epithelial cells to internalize sodium phosphate cotransporters and (2) reduced activation of vitamin D3 via inhibition of the renal enzyme 1-α hydroxylase. Low circulating levels of active vitamin D lead to reduced intestinal phosphate absorption and impaired mineralization of osteoid matrix. https://www.selleckchem.com/products/sbi-0640756.html TIO in breast cancer poses a distinct diagnostic challenge due to the common adjunct oncologic management with bone protection therapy such as denosumab or bisphosphonates. These agents can be culprits of hypophosphatemia and hypocalcemia, rendering timely diagnosis of TIO difficult. Delay of diagnosis of TIO can result in worsening functional status, and early morbidity and mortality. To date, there has been one prior case report of TIO in breast cancer, and herein we describe two additional cases of TIO in this setting.
Diffuse midline glioma (DMG) H3 K27M-mutant is a specific entity that, as the name indicates, tends to occur in midline structures including the thalamus, brainstem, and spinal cord. DMG predominates in children, is an aggressive tumor with poor prognosis, and is considered a WHO grade IV tumor regardless of histological features. The exact frequency of these mutations in adults diagnosed with glioma in the midline is unknown.

We report a series of 6 more adult cases, and we critically review the current literature on adults with DMG H3 K27M-mutant.

There were 5 males and 1 female. The age ranged from 26 to 52 years (median 39 years). All cases showed astrocytic differentiation, with positive staining for H3 K27M protein, and loss of H3 K27me in the tumor cells confirming the diagnosis.

H3 K27M-mutant midline glioma can occur in adults, affecting midline structures. Increasing awareness of the reporting pathologists of this entity might help in a better determination of the frequency of mutant DMG in adults as well as better diagnosis and patient counseling of the outcome.

Ductal stents, right ventricular outflow tract stents, and aortopulmonary shunts are used to palliate newborns and infants with reduced pulmonary blood flow. Current long-term outcomes of these palliations from resource-restricted countries are unknown.

This single-centre, retrospective, observational study analysed the technical success, immediate and late mortality, re-interventions, and length of palliation in infants ≤5 kg who underwent aortopulmonary shunts, ductal, and pulmonary outflow stents. Patients were grouped by their anatomy.

There were 69 infants who underwent one of the palliations. Technical success was 90% for aortopulmonary shunts (n = 10), 91% for pulmonary outflow stents (n = 11) and 100% for ductal stents (n = 48). Early mortality within 30 days in 12/69 patients was observed in 20% after shunts, 9% after pulmonary outflow stents, and 19% after ductal stents. Late mortality in 11 patients was seen in 20% after shunts, 18% after outflow stents, and 15% after ductal stents. Seven pat developing countries despite advances in intensive care and interventions.
Cyanotic infants, despite undergoing technically successful palliation had a high inter-stage mortality irrespective of the type of palliation. Duct stenting in univentricular hearts and in pulmonary atresia with an intact ventricular septum and adequate sized right ventricle tended to have low mortality and better long-term outcome. Completion of biventricular repair after palliation was achieved only in 63% of patients, reflecting unique challenges in developing countries despite advances in intensive care and interventions.The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on medical educational curricula. We aimed to examine the impact of these unprecedented changes on the formal education of paediatric cardiology fellows through a nationwide survey. A REDCap™-based voluntary anonymous survey was sent to all current paediatric cardiology fellows in the United States of America in May, 2020. Of 143 respondents, 121 were categorical fellows, representing over one-fourth of all categorical paediatric cardiology fellows in the United States of America. Nearly all (140/143, 97.9%) respondents utilised online learning during the pandemic, with 134 (93.7%) reporting an increase in use compared to pre-pandemic. The percentage of respondents reporting curriculum supplementation with outside lectures increased from 11.9 to 88.8% during the pandemic. Respondents considered online learning to be "equally or more effective" than in-person lectures in convenience (133/142, 93.7%), improving fellow attendance (132/142, 93.0%), improving non-fellow attendance (126/143, 88.1%), and meeting individual learning needs (101/143, 70.6%). The pandemic positively affected the lecture curriculum of 83 respondents (58.0%), with 35 (24.5%) reporting no change and 25 (17.5%) reporting a negative effect. A positive effect was most noted by those whose programmes utilised supplemental outside lectures (62.2 versus 25.0%, p = 0.004) and those whose lecture frequency did not decrease (65.1 versus 5.9%, p less then 0.001). Restrictions imposed by the COVID-19 pandemic have greatly increased utilisation of online learning platforms by medical training programmes. This survey reveals that an online lecture curriculum, despite inherent obstacles, offers advantages that may mitigate some negative consequences of the pandemic on fellowship education.
