Abstract
Glycocalyx disruption and hyperinflammatory responses are implicated in the pathogenesis of dengue-associated vascular leak, however little is known about their association with clinical outcomes of patients with dengue shock syndrome (DSS). We investigated the association of vascular and inflammatory biomarkers with clinical outcomes and their correlations with clinical markers of vascular leakage. We performed a prospective cohort study in Viet Nam. Children ≥5 years of age with a clinical diagnosis of DSS were enrolled into this study. Blood samples were taken daily during ICU stay and 7–10 days after hospital discharge for measurements of plasma levels of Syndecan-1, Hyaluronan, Suppression of tumourigenicity 2 (ST-2), Ferritin, N-terminal pro Brain Natriuretic Peptide (NT-proBNP), and Atrial Natriuretic Peptide (ANP). The primary outcome was recurrent shock. Ninety DSS patients were enrolled. Recurrent shock occurred in 16 patients. All biomarkers, except NT-proBNP, were elevated at presentation with shock. There were no differences between compensated and decompensated DSS patients. Glycocalyx markers were positively correlated with inflammatory biomarkers, haematocrit, percentage haemoconcentration, and negatively correlated with stroke volume index. While Syndecan-1, Hyaluronan, Ferritin, and ST-2 improved with time, ANP continued to be raised at follow-up. Enrolment Syndecan-1 levels were observed to be associated with developing recurrent shock although the association did not reach the statistical significance at the P &lt; 0.01 (OR = 1.82, 95% CI 1.07–3.35, P = 0.038). Cardiovascular and inflammatory biomarkers are elevated in DSS, correlate with clinical vascular leakage parameters and follow different kinetics over time. Syndecan-1 may have potential utility in risk stratifying DSS patients in ICU.
Critical Differences between Typical Arc Magmas and Giant Porphyry Cu ± Au Systems: Implications for Exploration

Published: June 2024

Abstract
Porphyry Cu, and porphyry Cu–Au deposits, are associated with arc magmatism and their ore-forming systems generally follow the magmatic evolution of typical arcs. However, most arc magmas are barren and giant economic porphyry Cu ± Au deposits are rare. In this study, we model variations in rare earth element concentrations in evolving arc magmas and giant porphyry Cu ± Au systems to quantify the percentage of the fractionating minerals required to produce the observed changes. We find that, during the andesitic stage of fractionation, ore-forming systems in thick crusts fractionate ~35% more amphibole than an average of thick arc magma systems (the thick-crust reference suite) and that ore-forming systems in thin crusts fractionate twice as much amphibole as their equivalent thin-arc magma reference suite. Thick-crust ore-forming suites also fractionate ~50% less plagioclase, and thin-crust ore systems ~40% less plagioclase, than their associated reference suites during the same andesitic stage of fractionation. Taken together, these observations imply that ore-producing magmas are appreciably wetter than their associated barren reference suites. Our modeling also shows that ~80% more amphibole is required to reproduce the andesite stage of fractionation in the thick-crust reference suite than in its thin-crust equivalent, suggesting that magmas produced under thick crusts are wetter than those produced under thin crusts. On the other hand, the chalcophile element contents of the thick- and thin-crust ore-forming systems are similar to and higher than those of the thick- and thin-crust reference suites, respectively. Therefore, we suggest that the high water content plays a critical role in the formation of giant porphyry Cu ore in thick crusts, whereas both high chalcophile contents and high water contents are required to form giant porphyry Cu–Au deposits in thin crusts. The high fraction of amphibole fractionation in giant economic porphyry suites, compared with their relevant reference suites, results in lower Y in the ore-associated suites and this difference increases with fractionation. As a consequence, plots of Y against MgO can be used to identify porphyries that have economic potential and are preferred to Sr/Y plots because they are less affected by the intense alteration associated with giant porphyry Cu ± Au deposits.

Abstract
Clinical bone-morphogenetic protein 2 (BMP2) treatment for bone regeneration, often resulting in complications like soft tissue inflammation and ectopic ossification due to high dosages and non-specific delivery systems, necessitates research into improved biomaterials for better BMP2 stability and retention. To tackle this challenge, we introduced a groundbreaking bone-targeted, lipoplex-loaded, three-dimensional bioprinted bilayer scaffold, termed the polycaprolactone-bioink-nanoparticle (PBN) scaffold, aimed at boosting bone regeneration. We encapsulated BMP2 within the fibroin nanoparticle based lipoplex (Fibroplex) and functionalized it with DSS6 for bone tissue-specific targeting. 3D printing technology enables customized, porous PCL scaffolds for bone healing and soft tissue growth, with a two-step bioprinting process creating a cellular lattice structure and a bioink grid using gelatin-alginate hydrogel and DSS6-Fibroplex, shown to support effective nutrient exchange and cell growth at specific pore sizes. The PBN scaffold is predicted through in silico analysis to exhibit biased BMP2 release between bone and soft tissue, a finding validated by in vitro osteogenic differentiation assays. The PBN scaffold was evaluated for critical calvarial defects, focusing on sustained BMP2 delivery, prevention of soft tissue cell infiltration and controlled fiber membrane pore size in vivo. The PBN scaffold demonstrated a more than eight times longer BMP2 release time than that of the collagen sponge, promoting osteogenic differentiation and bone regeneration in a calvarial defect animal. Our findings suggest that the PBN scaffold enhanced the local concentration of BMP2 in bone defects through sustained release and improved the spatial arrangement of bone formation, thereby reducing the risk of heterotopic ossification.

Objectives
Although factors associated with alcohol use have been researched at a population level, descriptions of the alcohol and other drug (AOD) treatment-seeking population in New South Wales (NSW), Australia, are limited. This study addresses this gap by analyzing sociodemographic and health characteristics in the NSW AOD treatment-seeking population.

Methods
Self-reported Australian Treatment Outcomes Profile data on substance use, health ratings, and sociodemographic factors were acquired from public AOD services (offering services from counseling to ambulatory/inpatient withdrawal management) in 6 administrative health districts from 2016 to 2019 (n = 14,287). Gaussian and multiple logistic regressions were conducted to examine associations between these factors and alcohol consumption quantity.

Results
Data were analyzed for patients seeking treatment for alcohol consumption specifically (n = 5929; median age, 44 years; 65% male). Valid alcohol consumption data were available for 5460 patients, among whom the mean volume of alcohol consumed was 311 standard drinks (3110 grams of ethanol) over the past 28 days and 15 standard drinks (150 grams of ethanol) per occasion. Higher volumes were consumed by males and those with recent experiences of violence and/or injecting drug use. Caring for children younger than 5 years and having above-median health ratings were associated with lower alcohol consumption.

Conclusions
This study contributes to the characterization of the NSW public AOD treatment population and identifies associations between alcohol consumption, sociodemographic factors, and health ratings among people seeking treatment for alcohol consumption. Findings point towards multilevel assessment and comprehensive interventions for people engaging in treatment for alcohol use. Future research should address barriers to treatment.
Kava Withdrawal Treated With Phenobarbital—A Case Report and Literature Review
Authors: Cassidy Ryan Michael , Burdick Kalli , Anesi Trevor , Daunis Daniel 
Published: June 2024

AbstractKava consumption is a traditional practice in Polynesian and Micronesian cultures. It has recently gained popularity in the United States for therapeutic and recreational use. We report the following case. A man presented to the emergency department after a fall while intoxicated on kava. He was medically admitted for altered mental status, facial and clavicle fractures, and hyponatremia. Psychiatry was consulted for management of delirium. On interview, he reported consuming escalating amounts of kava for weeks despite attempts to stop. He was diagnosed with acute kava withdrawal with hyperactive delirium, treated with phenobarbital load (860 mg) and taper (390 mg). Continuous dexmedetomidine drip to hospital day 3 treated sympathetic activation and breakthrough agitation. By day 4, his delirium resolved and remained in remission until discharge. We performed a systematic review for reports of kava withdrawal, returning 9 studies. Eight assessed withdrawal symptoms after cessation of a low controlled dose of kava extract with no symptoms noted. One reported a case series of heavy kava users with seizure-like events. No publications discussed treatment of kava withdrawal. To our knowledge, this is the first publication to describe kava withdrawal syndrome and its effective treatment with phenobarbital.
Quick Estimation of Minimum Hearing Levels Using a Binaural Multifrequency Stimulus Paradigm: Proof of Concept
Authors: Gargeshwari Aditi , Krishnan Ananthanarayan , Delgado Rafael E. 
Published: June 2024

Objectives:
Objective estimation of minimum hearing levels using auditory brainstem responses (ABRs) elicited by single frequency tone-bursts presented monaurally is currently considered the gold standard. However, the data acquisition time to estimate thresholds (for both ears across four audiometric frequencies) using this method usually exceeds the sleep time (ranging between 35 and 49 minutes) in infants below 4 months, thus providing incomplete information of hearing status which in turn delays timely clinical intervention. Alternate approaches using faster rate, or tone-burst trains have not been readily accepted due to additional hardware and software requirements. We propose here a novel binaural multifrequency stimulation paradigm wherein several stimuli of different frequencies are presented binaurally in an interleaved manner. The rationale here is that the proposed paradigm will increase acquisition efficiency, significantly reduce test time, and improve accuracy by incorporating an automatic wave V detection algorithm. It is important to note that this paradigm can be easily implemented in most commercial ABR systems currently used by most clinicians.

Design:
Using this binaural multifrequency paradigm, ear specific ABRs were recorded in 30 normal-hearing young adults to both tone-bursts, and narrow-band (NB) iChirps at 500, 1000, 2000, and 4000 Hz. Comparison of ABRs elicited by tone-bursts and narrow-band chirps allowed us to determine if NB iChirps elicited a more robust wave V component compared with the tone-bursts. ABR data were characterized by measures of minimum hearing levels; wave V amplitude; and response detectability for two electrode configurations (high forehead-C7; and high forehead-linked mastoids).

Results:
Consistent with the research literature, wave V response amplitudes were relatively more robust for NB iChirp stimuli compared with tone-burst stimuli. The easier identification and better detectability of wave V for the NB iChirps at lower stimulus levels contributed to their better thresholds compared with tone-burst elicited responses. It is important to note that binaural multifrequency hearing levels close to minimum hearing levels were determined in approximately 22 minutes using this paradigm—appreciably quicker than the 45 to 60 minutes or longer time required for threshold determination using the conventional single frequency method.

Conclusions:
Our novel and simple paradigm using either NB iChirps or tone-bursts provides a reliable method to rapidly estimate the minimum hearing levels across audiometric frequencies for both ears. Incorporation of an automatic wave V detection algorithm increases objectivity and further reduce test time and facilitate early hearing identification and intervention.

Published: June 2024

Study Design:
Retrospective cohort.

Objective:
The purpose of this study was to evaluate the effect of overdistraction on interbody cage subsidence.

Background:
Vertebral overdistraction due to the use of large intervertebral cage sizes may increase the risk of postoperative subsidence.

Methods:
Patients who underwent anterior cervical discectomy and fusion between 2016 and 2021 were included. All measurements were performed using lateral cervical radiographs at 3 time points – preoperative, immediate postoperative, and final follow-up >6 months postoperatively. Anterior and posterior distraction were calculated by subtracting the preoperative disc height from the immediate postoperative disc height. Cage subsidence was calculated by subtracting the final follow-up postoperative disc height from the immediate postoperative disc height. Associations between anterior and posterior subsidence and distraction were determined using multivariable linear regression models. The analyses controlled for cage type, cervical level, sex, age, smoking status, and osteopenia.

Results:
Sixty-eight patients and 125 fused levels were included in the study. Of the 68 fusions, 22 were single-level fusions, 35 were 2-level, and 11 were 3-level. The median final follow-up interval was 368 days (range: 181–1257 d). Anterior disc space subsidence was positively associated with anterior distraction (beta = 0.23; 95% CI: 0.08, 0.38; P = 0.004), and posterior disc space subsidence was positively associated with posterior distraction (beta = 0.29; 95% CI: 0.13, 0.45; P < 0.001). No significant associations between anterior distraction and posterior subsidence (beta = 0.07; 95% CI: −0.06, 0.20; P = 0.270) or posterior distraction and anterior subsidence (beta = 0.06; 95% CI: −0.14, 0.27; P = 0.541) were observed.

Conclusions:
We found that overdistraction of the disc space was associated with increased postoperative subsidence after anterior cervical discectomy and fusion. Surgeons should consider choosing a smaller cage size to avoid overdistraction and minimize postoperative subsidence.

Published: June 2024

Abstract

Background
This study aims to explore the significance of serum amylase levels in patients with organophosphorus pesticide (OP) poisoning and to provide a new perspective for evaluating the severity and prognosis of OP poisoning.

Methods
The clinical data of 67 patients with acute OP poisoning, who had been treated in the emergency department of the General Hospital of Ningxia Medical University between September 2020 and August 2022, were retrospectively analyzed. Using Spearman rank correlation, serum amylase levels during admission and severity of poisoning correlated with discharge outcomes. Based on serum amylase levels, receiver operating characteristic curves were plotted to predict the severity and mortality of patients who experience organophosphate poisoning. The optimal threshold serum amylase level at admission was determined based on the maximum Youden index.

Results
Using Spearman rank correlation analysis, serum amylase levels at admission positively correlated with the severity of poisoning and discharge outcomes, but the degree of correlation was weak (r
s: 0.344; 0.264; P < 0.05). The patients’ serum amylase levels at admission had receiver operating characteristic area under the curve values of 0.726 and 0.735 to predict the degree of severe poisoning and death, respectively. Based on the maximum Youden index, the optimal threshold of serum amylase were 97.8 and 194.1 U/L when the degree of poisoning was severe and the discharge outcome of patients was died. In comparison to patients with serum amylase levels ≤194.1 U/L at admission, the OR values of death in patients with serum amylase levels >194.1 U/L at admission was 15.944 (95% CI: 1.825–139.274).

Conclusion
Serum amylase levels in patients with organophosphate poisoning correlate with the degree of poisoning and discharge outcomes. Higher serum amylase level was a risk factor for organophosphorus poisoning death.
The Pathophysiology of Keratoconus
Authors: Vought Rita , Greenstein Steven A. , Gelles John , Hersh Peter S. 
Published: June 2024

Purpose:
Keratoconus is a progressive disease characterized by changes in corneal shape, resulting in loss of visual function. There remains a lack of comprehensive understanding regarding its underlying pathophysiology. This review aims to bridge this gap by exploring structural failures and inflammatory processes involved in the etiology and progression of keratoconus.

Methods:
A literature review was conducted using PubMed and Google Scholar databases, screening for articles published in English using the keyword combinations of “keratoconus” with “pathophysiology,” “pathology,” “metabolism,” “inflammatory,” “oxidative stress,” “cytokines,” “enzymes,” “collagen,” and “cornea.” Articles published between January 1, 1970, and June 1, 2023, were queried and reviewed, with greater emphasis placed on more recent data. Fifty-six relevant studies were examined to develop a thorough review of the pathophysiological mechanisms at play in keratoconus.

Results:
Biomechanical structural failures in the cornea seem to be the primary militating factors in keratoconus etiology and progression. These include disruptions in the arrangement in the collagen lamellae, a decrease in collagen levels, a decrease in natural collagen crosslinking, and changes in lysosomal enzyme activity. Immunologic changes have also been identified in keratoconus, challenging the traditional view of the condition as noninflammatory. Elevated levels of proinflammatory cytokines like IL-1b, IL-6, IL-17, and TNF-α have been observed, along with increased apoptosis of keratocytes. Increased oxidative stress leads to the activation of collagenase and gelatinase enzymes.

Conclusions:
Keratoconus is a complex condition influenced by both structural defects and inflammatory processes. Understanding these mechanisms can inform clinical management and potentially lead to more effective treatments.
Prognosis and immune infiltration analysis of m6A RNA methylation regulators in cutaneous melanoma and differential analysis with cuproptosis related genes
Authors: Tian Cui-cui , Shi Hao-ze , Zhang Cong-cong , Kong Ying-qi , Chen Hao 
Published: June 2024

Objective:
N6-methyladenosine (m6A) modification and cuproptosis play essential roles in the pathogenesis of various malignant tumors. However, the predictive role of m6A regulators and cuproptosis-related genes in cutaneous melanoma (CM) remains unclear. In this study, the aim was not only to explore the role of m6A modification in CM, but also to investigate the differential expression of cuproptosis-related genes in different risk group.

Methods:
We obtained transcriptome data from the XENA and GTEx databases. Univariate Cox regression analysis was performed to investigate the relationship between m6A-related genes and the outcomes of CM. LASSO regression analysis was utilized to construct a risk model. Moreover, we analyzed immune cell infiltration using CIBERSORT algorithms. Finally, we evaluated the expression levels of cuproptosis-related genes in CM samples and performed RT-qPCR to validate the expression of cuproptosis-associated genes in melanoma cells after YTHDF3 knockdown.

Results:
All m6A-related genes differed in melanoma tissues and normal tissues and a prognostic signature was developed. Immune infiltration revealed that low-risk group patients had a higher level of CD8 + T cells, memory activated CD4 + T cells, activated NK cells and M1 Macrophages than high-risk group (P<0.05). Moreover, the cuproptosis-related genes MTF-1, PDHB and FDX1 were significantly negatively associated with risk score (P=0.0007, P=0.0057 and P=0.04, respectively). We also found that downregulation YTHDF3 in melanoma cells affected the expression of cuproptosis-related genes. (P<0.01 and P<0.05).

Conclusion:
Our study demonstrated the prognostic value of m6A-related genes and cuproptosis-related genes in CM, providing new predictive models and potential therapeutic targets for CM.
