Published: July 2024

Abstract
Vulnerability curves (VCs) have been measured extensively to describe the differences in plant vulnerability to cavitation. Although the roles of hydraulic conductivity (Ks,max) and hydraulic safety (P50, embolism resistance), both of which are parameters of VCs (‘sigmoidal’ type), in tree demography have been evaluated across different forests, the direct linkages between VCs and tree demography are rarely explored. In this study, we combined measured VCs and plot data of 16 tree species in Panamanian seasonal tropical forests to investigate the connections between VCs and tree mortality, recruitment and growth. We found that the mortality and recruitment rates of evergreen species were most significantly positively correlated with P50. However, the mortality and recruitment rates of deciduous species only exhibited significant positive correlations with parameter a, which describes the steepness of VCs and indicates the sensitivity of conductivity loss with water potential decline, but is often neglected. These differences among evergreen and deciduous species may contribute to the poor performance of existing quantitative relationships (such as the fitting relationships for all 16 species) in capturing tree mortality and recruitment dynamics. Additionally, evergreen species presented a significant positive relationship between relative growth rate (RGR) and Ks,max, while deciduous species did not display such relationship. The RGR of both evergreen and deciduous species also displayed no significant correlations with P50 and a. Further analysis demonstrated that species with steeper VCs tended to have high mortality and recruitment rates, while species with flatter VCs were usually those with low mortality and recruitment rates. Our results highlight the important role of parameter a in tree demography, especially for deciduous species. Given that VC is a key component of plant hydraulic models, integrating measured VC rather than optimizing its parameters will help improve the ability to simulate and predict forest response to water availability.

Published: July 2024

To present the clinical and radiographic data, emphasize our surgical technique and how it was used, and the outcome measures in a case series of patients with chronic symptomatic peroneal sheath pain. A retrospective chart and radiograph review was conducted involving 36 adolescent patients (ages 8 to 20 y) treated surgically for chronic symptomatic peroneal sheath pain from 2010 to 2020. Findings that include chief complaint, magnetic resonance imaging findings, and surgical measures were documented. The patients’ postoperative and clinic visit notes were analyzed and outcome scores (FAOS Foot & Ankle Survey, AOFAS Ankle-Hindfoot Scale, and Kaikkonen Functional Scale) were calculated to determine the long-term results of the procedure. In our case series of 36 patients undergoing surgical treatment for chronic symptomatic peroneal sheath pain the procedures performed were as follows: 35 peroneal sheath repairs (97.22%), 34 ankle arthroscopies (94.44%), 27 resections of anomalous peroneus brevis muscle belly (75.00%), 2 resections of accessory peroneus quartus muscle (5.56%), 7 partial synovectomies (19.44%), 29 debridements (80.56%), and 6 Brostrom repairs (16.67%). magnetic resonance imaging findings showed 50% of our patient population had low-lying peroneus brevis muscles, and on examination during surgery, 61.11% of peroneus brevis muscles extended past the fibular tip. The average time in the cast post-operatively was 4.33 weeks. The average time from surgery to return to activity was 9.03 weeks. Twenty-two of the 36 patients (61.11%) were athletes and 100% were able to return to their sport. Outcome scores were retrospectively determined to be 99.27 for the FAOS Foot and Ankle Survey, 98.72 for the AOFAS Ankle-Hindfoot Scale, and 99.31 for the Kaikkonen Functional Scale. Complications were minimal and included 1 postoperative infection, 3 cast impingements, and 2 reported instances of post-operative pain. In our retrospective case series of 36 patients, the outcomes of surgical intervention for peroneal tendon pathology unresponsive to nonsurgical management in pediatric patients were evaluated. Our surgical method utilizes debridement, synovectomy, excision of low lying peroneus brevis muscle belly, excision of peroneus quartus if present, repair of split-tears of the tendons, and repair of the peroneal tendon sheath using “pants over vest” sutures to tighten the sheath. Our chart review shows all 36 patients were satisfied with the outcome, demonstrated improvement in relevant patient-reported outcome measures, and would elect to undergo the procedure again. Therefore, the novel surgical techniques outlined in this study appear to be viable options to treat chronic symptomatic peroneal tendon sheath pain resistant to conservative methods.

Early Fluid Is Less Fluid: Comparing Early Versus Late ICU Resuscitation in Severely Injured Trauma Patients
Authors: Beni Catherine E. , Arbabi Saman , Robinson Bryce R. H. , O’Keefe Grant E. 
Published: July 2024

OBJECTIVES:
The temporal trends of crystalloid resuscitation in severely injured trauma patients after ICU admission are not well characterized. We hypothesized early crystalloid resuscitation was associated with less volume and better outcomes than delaying crystalloid.

DESIGN:
Retrospective, observational.

SETTING:
High-volume level 1 academic trauma center.

PATIENTS:
Adult trauma patients admitted to the ICU with emergency department serum lactate greater than or equal to 4 mmol/dL, elevated lactate (≥ 2 mmol/L) at ICU admission, and normal lactate by 48 hours.

INTERVENTIONS:
None.

MEASUREMENTS AND MAIN RESULTS:
For the 333 subjects, we analyzed patient and injury characteristics and the first 48 hours of ICU course. Receipt of greater than or equal to 500 mL/hr of crystalloid in the first 6 hours of ICU admission was used to distinguish early vs. late resuscitation. Outcomes included ICU length of stay (LOS), ventilator days, and acute kidney injury (AKI). Unadjusted and multivariable regression methods were used to compare early resuscitation vs. late resuscitation. Compared with the early resuscitation group, the late resuscitation group received more volume by 48 hours (5.5 vs. 4.1 L; p ≤ 0.001), had longer ICU LOS (9 vs. 5 d; p ≤ 0.001), more ventilator days (5 vs. 2 d; p ≤ 0.001), and higher occurrence rate of AKI (38% vs. 11%; p ≤ 0.001). On multivariable regression, late resuscitation remained associated with longer ICU LOS and ventilator days and higher odds of AKI.

CONCLUSIONS:
Delaying resuscitation is associated with both higher volumes of crystalloid by 48 hours and worse outcomes compared with early resuscitation. Judicious crystalloid given early in ICU admission could improve outcomes in the severely injured.

Abstract

Background:
Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.

Methods:
A total of 3053 healthy Han Chinese adults (1922 women) aged 18–79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere–Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.

Results:
All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex.

Conclusions:
The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Published: July 2024

Abstract

Background:
Digestive system cancers constitute a significant number of cancer cases, but their burden is not uniform. As Global Cancer Observatory (GLOBOCAN) 2022 has recently updated its estimates of cancer burden, we aimed to investigate the burden of six major digestive system cancers both worldwide and in China, along with geographical and temporal variations in cancer-specific incidence and mortality.

Methods:
We extracted data on primary cancers of the esophagus, stomach, colorectum, liver, pancreas, and gallbladder from the GLOBOCAN database for 2022. Age-standardized incidence and mortality rates were calculated and stratified by sex, country, region, and human development index (HDI). We used the 2022 revision of the World Population Prospects (United Nations) to obtain demographic data for various age groups in China from 1988 to 2012 and used the joinpoint model and the average annual percentage change (AAPC) to analyze cancer incidence trends in China.

Results:
In 2022, the estimated global incidence of digestive system cancers reached 4,905,882, with an estimated 3,324,774 cancer-related deaths. Colorectal cancer was most prevalent in terms of incidence and mortality. There was a significant correlation between the burden of gastrointestinal cancers and country HDI. From 1988 to 2012, the incidence of esophageal, gastric, and liver cancers declined in China, whereas colorectal and pancreatic cancer incidences continued to increase. By 2050, colorectal and liver cancers are projected to remain the leading cancer types in China in terms of incidence and mortality, respectively.

Conclusions:
Digestive system cancers remain a significant public health challenge globally and in China. Although progress has been made in the prevention and control of some cancers, the burden of digestive system cancers persists. The implementation of tertiary prevention strategies must be intensified to reduce the incidence and mortality of digestive system cancers, mitigating their impact on public health.

Published: July 2024

Introduction:
The prevalence of infertility has increased worldwide. The etiological factors are also changing in trend and prominence. Male infertility is driving the epidemic in many regions of the world. Therefore, the aim of this study was to explore male factor infertility in the Gambia.

Methodology:
The design was a longitudinal descriptive study of subfertile couples at a specialist tertiary hospital in Banjul, the Gambia, from August 2022 to May 2023. Data were extracted from patients folders and entered into a computer database. Descriptive statistics were used to analyze the data and results expressed in tables, graphs, and percentages.

Results:
Total number of subfertile couples analyzed was 152: male factor 69 (45.4%), ovulation disorder 34 (22.4%), tubal factor 20 (13.2%), uterine factor 8 (5.3%), and unexplained 21 (13.8%). The median age of male folk was 50 years, with an age range of 31 to 64 years. The rates of asthenoteratozospermia, oligospermia, and azospermia were 37.8%, 36.2%, and 26%, respectively. In azoospermic males, over 75% had elevated FSH (12–44 miu/mL).

Conclusions:
The prevalence of male infertility is at 45.4%, which is 3-fold and 2-fold higher than tubal and ovarian factors, respectively. Male infertility is a problem with obvious implications. The predominant types of male infertility we observed in this study will almost always require multidisciplinary care and ICSI.
Spherical equivalent prediction analysis in intraocular lens power calculations using Eyetemis: a comprehensive approach
Authors: Kan-Tor Yoav , Abulafia Adi , Zadok David , Kohnen Thomas , Savini Giacomo , Hoffer Kenneth J. , Benjamini Yuval 
Published: July 2024

Purpose:
To compare 2 different datasets, using Eyetemis, an online analytical tool designed for assessing the spherical equivalent prediction errors (SEQ-PEs) of intraocular lens (IOL) power calculation formulas after cataract surgery.

Setting:
Institutional.

Design:
Retrospective case series.

Methods:
The study comprised 2 distinct datasets of patients who had undergone successful cataract surgery. Dataset 1 includes standard eyes, whereas Dataset 2 includes eyes with keratoconus. An online tool was used for SEQ-PE analysis across the 2 datasets, adhering to ISO standards for evaluating accuracy based on trueness and precision. The tool incorporates robust t tests for comparing the trimmed mean of the data, adjusting for heteroscedasticity. IOL constants in Dataset 1 were optimized for the comparison of Hoffer Q, Holladay 1, SRK/T, Haigis, and Barrett Universal II (BUII) formulas. In Dataset 2, IOL constants from the IOLCon website were used for the comparison of the BUII and its designated KCN version: Barrett TrueK Keratoconus (TrueK [KCN]).

Results:
For Dataset 1, the trimmed mean SEQ-PE values of all formulas were not significantly different from zero. BUII had superior precision and accuracy compared with all other formulas, except from Haigis (P ≤ .04). For Dataset 2, BUII's trimmed-mean SEQ-PE was significantly different from zero (0.59 diopters [D], P < .01), unlike the TrueK (KCN) (0.12 D, P = .10). In addition, TrueK (KCN) exhibited enhanced precision and accuracy relative to BUII (P < .01).

Conclusions:
The online analysis tool provides a streamlined approach for assessing the prediction accuracy of SEQ refraction after cataract surgery, effectively evaluating trueness, precision, and overall accuracy through the use of advanced statistical methods.
Protected cardiac surgery: strategic mechanical circulatory support to improve postcardiotomy mortality
Authors: Salazar Leonardo , Lorusso Roberto 
Published: July 2024

Purpose of review
To examine the evolving landscape of cardiac surgery, focusing on the increasing complexity of patients and the role of mechanical circulatory support (MCS) in managing perioperative low cardiac output syndrome (P-LCOS).

Recent findings
P-LCOS is a significant predictor of mortality in cardiac surgery patients. Preoperative risk factors, such as cardiogenic shock and elevated lactate levels, can help identify those at higher risk. Proactive use of MCS, rather than reactive implementation after P-LCOS develops, may lead to improved outcomes by preventing severe organ hypoperfusion. The emerging concept of “protected cardiac surgery” emphasizes early identification of these high-risk patients and planned MCS utilization. Additionally, specific MCS strategies are being developed and refined for various cardiac conditions, including AMI-CS, valvular surgeries, and pulmonary thromboendarterectomy.

Summary
This paper explores the shifting demographics and complexities in cardiac surgery patients. It emphasizes the importance of proactive, multidisciplinary approaches to identify high-risk patients and implement early MCS to prevent P-LCOS and improve outcomes. The concept of protected cardiac surgery, involving planned MCS use and shared decision-making, is highlighted. The paper also discusses MCS strategies tailored to specific cardiac procedures and the ethical considerations surrounding MCS implementation.
Strategies to minimize procedure-related pain and anxiety: lessons from pediatric dermatology
Authors: Abouchaleh Nadine , Bayart Cheryl 
Published: July 2024

Purpose of reviewRecent studies have suggested that prolonged or repeated episodes of general anesthesia early in childhood may adversely affect neurodevelopment. This, combined with rising healthcare costs and decreasing access, has sparked interest in performing pediatric procedures in the office setting when possible. It is essential to address the physical and psychological discomfort that often accompany this experience, particularly in children.Recent findingsHealthcare providers performing procedures on children can draw from a spectrum of established techniques, new technology, and novel use of medications to decrease peri-procedural pain and anxiety. These techniques include distraction, optimization of local anesthesia, and mild to moderate sedation.SummaryWe recommend using a combination of techniques to minimize pain and anxiety to improve safety, decrease healthcare costs, improve patient experience, and prevent childhood trauma and persistent negative perception of the healthcare system.
What's new in pediatric genetic cholestatic liver disease: advances in etiology, diagnostics and therapeutic approaches
Authors: Pinon Michele , Kamath Binita M. 
Published: July 2024

Purpose of reviewTo highlight recent advances in pediatric cholestatic liver disease, including promising novel prognostic markers and new therapies.FindingsAdditional genetic variants associated with the progressive familial intrahepatic cholestasis (PFIC) phenotype and new genetic cholangiopathies, with an emerging role of ciliopathy genes, are increasingly being identified. Genotype severity predicts outcomes in bile salt export pump (BSEP) deficiency, and post-biliary diversion serum bile acid levels significantly affect native liver survival in BSEP and progressive familial intrahepatic cholestasis type 1 (FIC1 deficiency) patients. Heterozygous variants in the MDR3 gene have been associated with various cholestatic liver disease phenotypes in adults. Ileal bile acid transporter (IBAT) inhibitors, approved for pruritus in PFIC and Alagille Syndrome (ALGS), have been associated with improved long-term quality of life and event-free survival.SummaryNext-generation sequencing (NGS) technologies have revolutionized diagnostic approaches, while discovery of new intracellular signaling pathways show promise in identifying therapeutic targets and personalized strategies. Bile acids may play a significant role in hepatic damage progression, suggesting their monitoring could guide cholestatic liver disease management. IBAT inhibitors should be incorporated early into routine management algorithms for pruritus. Data are emerging as to whether IBAT inhibitors are impacting disease biology and modifying the natural history of the cholestasis.

Published: July 2024

OBJECTIVES:
To identify and prioritize research questions for anticoagulation and hemostasis management of neonates and children supported with extracorporeal membrane oxygenation (ECMO) from the Pediatric ECMO Anticoagulation CollaborativE (PEACE) consensus.

DATA SOURCES:
Systematic review was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021, followed by serial consensus conferences of international, interprofessional experts in the management of ECMO for critically ill neonates and children.

STUDY SELECTION:
The management of ECMO anticoagulation for critically ill neonates and children.

DATA EXTRACTION:
Within each of the eight subgroups, two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts.

DATA SYNTHESIS:
Following the systematic review of MEDLINE, EMBASE, and Cochrane Library databases from January 1988 to May 2021, and the consensus process for clinical recommendations and consensus statements, PEACE panel experts constructed research priorities using the Child Health and Nutrition Research Initiative methodology. Twenty research topics were prioritized, falling within five domains (definitions and outcomes, therapeutics, anticoagulant monitoring, protocolized management, and impact of the ECMO circuit and its components on hemostasis).

CONCLUSIONS:
We present the research priorities identified by the PEACE expert panel after a systematic review of existing evidence informing clinical care of neonates and children managed with ECMO. More research is required within the five identified domains to ultimately inform and improve the care of this vulnerable population.
