Erroneous weight estimation during the management of emergency presentations in adults may contribute to patient harm and poor outcomes. Patients can often not be weighed during emergencies and a weight estimation is required to facilitate weight-based therapies. Many existing methods of weight estimation are either unacceptably inaccurate or very difficult to use during the provision of emergency care.

The weight estimation system developed in this study was based on and modified from the PAWPER XL-MAC method, a pediatric weight estimation system that uses recumbent length and mid-arm circumference (MAC) to predict total body weight. This model was validated in the 2015-2018 National Health and Nutrition Examination Survey (NHANES) datasets. The primary outcome measure was to achieve >95% of estimations within 20% of measured weight (P20>95%).

The modified PAWPER XL-MAC model achieved a P20 of 96.0% and a P10 of 71.3% in the validation dataset (N=11,520). This accuracy (P20>95%) was maintained in both sexes, all ages, all ethnic groups, all lengths and in all habitus-types, except for the subgroup of severely obese individuals.

The modified PAWPER XL-MAC model proved to be a very accurate method of weight estimation. It is more accurate than most other published reports of existing methods of weight estimation, except for patients' own estimations. It therefore could have a role in facilitating emergency drug dose calculations, if prospective studies bear out the accuracy found in this study.

The field of infant magnetic resonance imaging, by comparison, is a young field with tremendous scientific potential but continuously evolving standards. The present article aims to initiate a constructive dialog between researchers who grapple with the challenges and inherent limitations of a nascent field and reviewers who evaluate their work. We address 20 questions that researchers commonly receive from research ethics boards, grant, and manuscript reviewers related to infant neuroimaging data collection, safety protocols, study planning, imaging sequences, decisions related to software and hardware, and data processing and sharing, while acknowledging both the accomplishments of the field and areas of much needed future advancements. This article reflects the cumulative knowledge of experts in the FIT'NG community and can act as a resource for both researchers and reviewers alike seeking a deeper understanding of the standards and tradeoffs involved in infant neuroimaging.The diagnostic utility of neuroradiologic signs associated with idiopathic intracranial hypertension (IIH) for the evaluation of patients presenting with papilloedema remains yet to be elucidated. This multicentre retrospective cohort study assessed consecutive patients presenting with suspected papilloedema to Auckland District Health Board (NZ) and Stanford University Medical Centre (US), between 2005 and 2019, undergoing magnetic resonance imaging and venography (MRI/MRV) or computed tomography and venography (CT/CTV) prior to lumbar puncture assessment for diagnostic suspicion of IIH. Data were collected regarding demographic, clinical, radiologic, and lumbar puncture parameters, and the diagnosis of IIH was determined according to the Friedman criteria for primary pseudotumor cerebri syndrome. A total of 204 participants (174 females; mean ± SD age 29.9 ± 12.2 years) were included, and 156 (76.5%) participants fulfilled the diagnostic criteria for IIH. The presence of any IIH-associated radiologic sign on MRI/MRV demonstrated a sensitivity (95% CI) of 74.8% (65.8%-82.0%) and specificity (95% CI) of 94.7% (82.7%-98.5%), while radiologic signs on CT/CTV exhibited a sensitivity (95% CI) of 61.0% (49.9%-71.2%) and specificity (95% CI) of 100.0% (83.2%-100.0%). In summary, the modest sensitivities of radiologic signs of IIH would support the routine use of lumbar puncture assessment following neuroimaging to secure the diagnosis. However, the high specificities might lend limited support for the judicious deferment of lumbar puncture assessment among typical IIH demographic patients who consent to the inherent small risk of missed pathology, which has been proposed by some clinicians.Adolescents and Young Adults (AYA), have distinct endocrine and psychosocial peculiarities. Brain tumors occur less among AYAs, compared to other age groups and with better prognosis. There is however a paucity of literature about brain tumors in AYA in sub-Saharan Africa. We aim to describe the clinical characteristics of brain tumors in AYA across five neurosurgical centers in Nigeria and the associated factors. We report results for older children (10-14 years), adolescents (15-19 years) and young adults (20-24 years). This was a retrospective review of AYA with brain tumors over a 10-year period (2010-2019). Data analysis was by descriptive statistics, Chi square test and multinomial regression at α0.05. There were 104 AYAand the male to female ratio was 1.21. Headache (79.8%) and visual symptoms (65.4%) were the most common presenting symptoms. Focal limb weakness (44.1%) occurred less frequently. Median duration of symptoms prior to presentation was 9 months. Glioma was the most common tumor (31, 29.8%) while pituitary adenoma and craniopharyngioma constituted 30.8% of the tumors. Patients with symptom duration of ≤one year were more likely to have infratentorial tumors. There was no significant association between the KPS following intervention and the AYA characteristics. Age group was not significantly associated with any of the presenting symptoms except ataxia, which was significantly higher among the 10 to 14 years group.We have described the epidemiology of brain tumors within AYA in Nigeria and highlighted a need to maximize their care and meet their special needs.
To summarize the prevalence of the cardiovascular comorbidities in patients with amyotrophic lateral sclerosis (ALS) and explore the impacts of cardiovascular diseases on ALS.

PubMed, EMBASE, OVID and Web of Science were searched systematically until July 2021 for studies on the prevalence of cardiovascular diseases among ALS patients or quantitatively investigating the effects of cardiovascular comorbidities on incidence, progression or survival of ALS. We conducted a fixed-effects or random-effects meta-analysis to calculate the summary rate or ORs (odds ratios) with 95 %CIs (confidence intervals).

The comorbidity of hypertension in France (56.9%) was the highest, followed by Portugal (48%). Only 15% of Chinese ALS patients suffered from hypertension. A quarter of ALS patients in America had coronary heart disease while only 4-5% of patients with ALS in Australia or the Netherlands suffered from coronary heart disease. There was significant relationship between hypertension and survival of ALS (OR 1.0ans.The aim of our study was to evaluate the association between intracranial arterial tortuosity and cardiovascular outcome in patients with Loeys-Dietz syndrome (LDS). We performed a retrospective analysis of all patients with genetically confirmed LDS who underwent at least one brain MRA at our institution (n = 32); demographic and clinical features were evaluated in relation to the tortuosity of intracranial arteries as measured by tortuosity index (TI), which was calculated using the formula [(centerline length) / (straight-line length)-1] × 100. Receiver operating characteristic curve analysis for intracranial TI and the binary end point of aortic surgery showed vertebrobasilar TI (VBTI) to be the best classifier among the examined arterial segments (AUC = 0.822). Patients with higher VBTI showed a greater incidence of aortic surgery (p less then 0.001) and underwent more surgical and endovascular procedures (p = 0.006), with a higher rate of operations (p = 0.002). Kaplan-Meier analysis showed a significantly longer surgery-free survival in patients with lower arterial tortuosity (p less then 0.001). At multivariate analysis, higher VBTI was associated with an increased risk of surgery (p less then 0.001), which was independent of gene mutation and patient age. Increased VBTI is a marker of adverse cardiovascular outcome in patients with LDS, which can be easily measured on brain MRA, and may be useful in the management of this heterogeneous patient population.In the quest for medicinally active compounds in mushrooms of the genus Ganoderma, eleven undescribed lanostane triterpenoids, including a novel chlorinated derivative, i.e., (20S,24E)-21-chloro-15β,20,29-trihydroxy-3,7,11-trioxolanosta-8,24-dien-26-oic acid, were isolated from artificially cultivated fruiting bodies of the basidiomycete Ganoderma mbrekobenum. The structures were elucidated on the basis of NMR spectroscopic and mass spectrometry data. The configuration of the C-20 atom in the most abundant 20-hydroxy-lanostane, (20S,24E)-15β,20,29-trihydroxy-3,7,11-trioxolanosta-8,24-dien-26-oic acid, was established by chemical derivatization, and the absolute configuration of the lanostane skeleton was determined by ECD calculation. Two of the undescribed compounds exhibited moderate antimalarial activity.
To evaluate the macula microvascular perfusion in neuromyelitis optica spectrum disorder (NMOSD) patients and assess the correlation with their clinical features.

35 aquaporin-4 seropositive NMOSD patients (38 NMOSD eyes without optic neuritis, NMOSD-NON, and 32 NMOSD eyes with optic neuritis) and 35 healthy controls (HC) were included in our study. Swept-source optical coherence tomography angiography (SS-OCTA) was used to image and segment the macula microvasculature into the inner macula vascular complex (IVC), superficial vascular plexus (SVC), and deep vascular plexus (DVC). An inbuilt software within the OCTA tool was used to measure the microvascular perfusion in these two plexuses.

NMOSD eyes without optic neuritis showed sparser (P < 0.05) IVC and SVC compared with healthy controls; NMOSD eyes with optic neuritis showed significantly sparser (P < 0.001) IVC, SVC, and DVC when compared with healthy controls respectively. NMOSD eyes with optic neuritis showed significantly sparser IVC (P=0.002), SVC (P=0.001) and DVC (P= =0.040) when compared with eyes without optic neuritis.

Microvascular impairment in NMOSD patients occurs independently of ON. Microvascular impairment is associated with reduced visual acuity and frequency of ON.

With only one phase III trial published to date and two indications approved for routine clinical use by the FDA, we reviewed the entire clinical trial portfolio to broadly understand mtIDH1 inhibitor activity in patients. We queried PubMed.gov and ClinicalTrials.gov to identify published and ongoing clinical trials related to IDH1 and cancer. Progression-free survival (PFS), overall survival (OS), 2-hydroxyglutarate levels, and adverse events were summarized. To date, ten clinical trials investigating mtIDH1 inhibitors among patients with diverse malignancies (cholangiocarcinoma, acute myeloid leukemia, chondrosarcoma, glioma) have been published. Almost every trial (80%) has investigated ivosidenib. In multiple phase I trials, ivosidenib treatment resulted in promising radiographic and biochemical responses with improved survival outcomes (relative to historic data) among patients with both solid and hematologic mtIDH1 malignancies.
