Authors: Lalwani Kunal , De La Haye Winston , Kerr Kevon , Abel Wendel , Sewell Clayton 
Published: November 2024

BackgroundThere is an increasing demand for the treatment of problematic cannabis use (PCU) in low-income and middle-income countries. Jamaica’s historical inclination towards cannabis use underscores the need for research in addressing this issue.ObjectivesTo determine the prevalence and patterns of cannabis use and assess the sociodemographic factors, psychosocial correlates, knowledge and perceptions associated with severe PCU among Jamaicans using nationally representative data.MethodsThis study involved a secondary data analysis of the last Jamaica National Drug Prevalence Survey. It included 786 participants who used cannabis in the past year and completed the Cannabis Abuse Screening Test (CAST). The CAST has been validated against the Diagnostic and Statistical Manual of Mental Disorders (DSM), with a score ≥ 7 meeting the criteria for severe PCU. CAST scores were dichotomized utilizing these thresholds, and data generated were analyzed with SPSS version 25 using Pearson’s χ2 test and logistic regression.ResultsIn the past year, 53.3% of Jamaicans who smoked cannabis had a score of 7 or higher on the CAST and smoked an average of 62.21 joints per month. Male respondents were twice as likely to have severe PCU as females. Additionally, young, middle, and older adults were respectively 3, 5 and 3 times more likely to report severe PCU compared to adolescent respondents. Participants who started cannabis use at 11 years and under, 12-17 years, and 18-25 years were respectively 5, 7 and 7 times more likely to report severe PCU than those at 26 years and older. Moreover, easy access to cannabis, a high perceived need for treatment, belief in increased national drug use prevalence, and awareness of the National Drug Control and Prevention Agency were associated with increased odds of reporting severe PCU.ConclusionOne out of every two Jamaicans who used cannabis in the past year reported severe PCU and smoked an average of two cannabis joints per day. Early initiation increases the risk of severe PCU. Accordingly, a public health approach involving multiple sectors is needed to provide treatment options.

IntroductionThe experiences of patients receiving health care constitute an important aspect of health-care quality assessments. One of the purposes of the national program of patient-experience surveys in Norway is to support institutional and departmental improvements to the quality of local health-care services. This program includes national surveys of patients receiving interdisciplinary treatment for substance dependence performed four times between 2013 and 2017. The aims of this study were twofold: (i) to determine the attitudes of employees towards these surveys and their use of the survey results, and (ii) to identify changes in patient experiences at the national level from 2013 to 2017.Material and methodsEmployees were surveyed one week prior to conducting cross-sectional patient experience surveys. One-way ANOVA and chi-square tests were used to assess differences between years, and content analysis was applied to the open-ended comments.ResultsAround 400 employees were recruited in each of the four survey years, and the response rate varied from 61% to 79%. The employees generally reported a positive attitude towards patient-experience surveys, and 40%–50% of them had implemented quality initiatives based on the results of the patient surveys. The mean score for the question on usefulness was higher than 3 (on a Likert scale from 1 to 5 points) for all four surveys. Many employees provided details about the changes that had been made in open-ended comments. The results from the patient-experience surveys demonstrated positive changes over time.DiscussionThe employees had positive viewpoints towards patient-experience surveys, and around half of them had implemented quality initiatives. This implies that employees find such surveys important, and that patient-experience surveys are regarded as useful and actionable. The surveys of patients showed positive changes in their experiences over time. The most-common target areas reported by employees showed clear improvements in patient experiences at the national level.

IntroductionThe endometrium plays a crucial role in early human pregnancy, particularly in embryo implantation, survival, and growth. However, invasion and infection by pathogens can lead to endometritis, infertility, and poor reproductive outcomes. Understanding the mechanisms of endometritis and its impact on fertility remains limited. An infection model using patient-derived endometrial epithelial gland organoids (EEGOs) was established to advance in vitro studies on endometritis and related infertility.MethodsAn EEGOs infection model was constructed and characterized from human endometrium, treating the organoids with estrogen and progesterone to observe changes in the proliferative and secretory phases. The organoids were infected with E. coli, and the release of inflammatory cytokines in the supernatant was detected using ELISA. RNA-seq was employed to analyze the differences before and after E. coli treatment, and differential gene mRNA expression was validated using real-time quantitative PCR. Additionally, the effect of E2 in alleviating inflammation was assessed through markers of receptivity (PAEP, LIF, ITGβ), proliferation (Ki67), and barrier repair (ZO-1).ResultsThe constructed human EEGOs exhibited long-term expansion capability, genetic stability, and characteristic hormonal responses, strongly expressing epithelial markers (MUC1, E-Cadherin). After E. coli infection, the expression levels of inflammatory cytokines TNF-α, IL-8, and IFN-γ increased significantly (P &lt; 0.05). RNA-seq indicated that the MAPK signaling pathway was activated post-infection, with increased expression levels of heat shock proteins and transcription factor mRNA. E2 treatment post-infection significantly decreased the mRNA expression of inflammatory genes IL-1β, IL8, IL6 and TNF-α compared to the E. coli infected group (P &lt; 0.05). Additionally, the expression of genes related to receptivity, proliferation, and barrier repair was enhanced in the E2-treated organoids.ConclusionsOur findings demonstrate that patient-derived EEGOs are responsive to bacterial infection and are effective models for studying host-pathogen interactions in bacterial infections. These organoids revealed the anti-inflammatory potential of E2 in alleviating E. coli-induced inflammation, providing insights into the mechanisms of endometritis and its impact on infertility. The study supports the use of EEGOs as valuable tools for understanding endometrial health and developing targeted treatments.
Comparative clinical efficacy of single-incision thoracoscopic bullectomy combined with C-shaped electrocautery pleurodesis vs. chemical pleurodesis in the management of spontaneous pneumothorax

Published: November 2024

ObjectiveThis study aims to observe the clinical efficacy of single-incision thoracoscopic bullectomy combined with C-shaped electrocautery pleurodesis compared to traditional iodine chemical pleurodesis in the treatment of patients with spontaneous pneumothorax.MethodsA total of 128 patients with spontaneous pneumothorax who underwent surgical treatment at our institution from January 2021 to December 2022 were selected. Patients were categorized into the study group (n = 65) and the control group (n = 63) based on the surgical method used. The study group received C-shaped pleura cautery for pleurodesis, while the control group underwent traditional iodine chemical pleurodesis. Surgical and clinical outcomes were evaluated, and recurrence rates within one year postoperatively were compared. Serum C-reactive protein (CRP) levels and visual analog scale (VAS) scores were measured at different time points.ResultsNo significant differences were observed between the two groups regarding surgical duration, intraoperative blood loss, or postoperative hospital stay (p &gt; 0.05). However, the study group demonstrated significantly lower serum CRP levels and VAS scores on postoperative days 1 and 2, as well as reduced drainage volumes compared to the control group (p &lt; 0.05). The recurrence rates of pneumothorax within one year postoperatively did not differ significantly between the groups (p &gt; 0.05).ConclusionSingle-incision thoracoscopic bullectomy combined with C-shaped electrocautery pleurodesis is an effective treatment for spontaneous pneumothorax. Compared to traditional iodine chemical pleurodesis, this method causes less pleural irritation, results in lower postoperative pain and drainage, and facilitates patient recovery, making it a safe and reliable option for the management of spontaneous pneumothorax.

Published: November 2024

IntroductionOphthalmic ultrasound is useful tool for examining canine eyes. Previous studies have compared ocular parameters using ophthalmic ultrasonography based on body weight, breed, sex, and age. However, there are limited studies involving large numbers of dogs with controlled body condition score. Furthermore, to the authors' knowledge, there are no established parameters that can be used independently of body weight. The aim of this study was (1) to compare ultrasonography ocular parameters based on body weight, breed, sex, and age in dogs with an ideal body condition score, (2) to establish normal reference ranges for ultrasonography ocular parameters on a large number of samples, (3) to establish an ultrasonography ocular parameter ratio that can be used regardless of body weight.MethodsA total of 225 dogs were collected, of which 120 dogs without abnormalities on ophthalmologic and clinical examinations were included according to the inclusion criteria. The ocular parameters measured were the anterior chamber (AC), vitreous chamber (VC), lens axial length (LAL), lens equatorial length (LEL), and globe axial length (GAL).ResultsIn LEL and GAL, a strong positive correlation was observed with body weight, and significant differences were identified between all body weight groups (p &lt; 0.05). The mean LEL for each body weight groups is as follows: 1 ≤ body weight &lt; 5 kg; 1.118 ± 0.032 cm, 5 ≤ body weight &lt; 10 kg; 1.17 ± 0.03 cm, 10 ≤ body weight &lt; 20 kg; 1.218 ± 0.018 cm, 20 ≤ body weight &lt; 35 kg; 1.313 ± 0.03 8cm (R2 = 0.820; β = 0.008; p &lt; 0.001). The mean GAL for each body weight groups is as follows: 1 ≤ body weight &lt; 5 kg; 1.731 ± 0.076 cm, 5 ≤ body weight &lt; 10 kg; 1.841 ± 0.064 cm, 10 ≤ body weight &lt; 20 kg; 1.915 ± 0.043 cm, 20 ≤ body weight &lt; 35 kg; 2.027 ± 0.059 cm (R2 = 0.598; β = 0.012; p &lt; 0.05). The positive correlation with body weight was weaker for the AC, VC, and LAL than for the LEL and GAL. No significant differences were found among breeds, sexes, or ages, nor between the left and right eyes in all ocular parameters (p &gt; 0.05). And we found that LEL:GAL ratio has no correlation with body weight (0.642 ± 0.022; R2 = −0.006; β = 0.000; p &gt; 0.05).DiscussionThis study identified significant correlations between LEL, GAL, and body weight in dogs with ideal body condition. We established normal reference ranges for ocular parameters within each BW group and breed based on a large number of samples. In addition, we present the LEL:GAL ratio, which is a constant value regardless of body weight or breed, as expected to be clinically useful in ocular evaluation.

Published: November 2024

Climate change alters vegetation patterns, pushing subtropical forests further north. These forests play a crucial role for carbon neutrality efforts due to their significant CO2 assimilation potential. This study investigated CO2 assimilation rate along with growth, morphological, and physiological traits in 23 half-sib families of Quercus acuta and 26 half-sib families of Q. glauca, two prominent East Asian evergreen broadleaf species. Q. acuta exhibited significantly higher growth rates, with diameter at breast height (DBH) and aboveground biomass exceeding those for Q. glauca by 12.1% and 69.9%, respectively (p < 0.001). Leaf traits, including leaf mass pear area (LMA), leaf nitrogen, and chlorophyll content, were also greater in Q. acuta, showing 24.5%, 45.8%, and 15.6% higher values (p < 0.001). While photosynthetic traits were similar, Q. acuta exhibited a 12.7% higher intrinsic water-use efficiency (iWUE) (p < 0.01). Among half-sib families, marginal differences were observed in growth traits (p < 0.1), and significant differences in leaf morphology and physiological traits (p < 0.05) were observed. A positive correlation was found between growth and physiological traits associated with the CO2 assimilation rate in Q. acuta, but not in Q. glauca. These findings highlight the potential of Q. acuta and Q. glauca for supporting future carbon neutrality efforts and provide traits supporting carbon uptake, valuable for selecting tree species with enhanced carbon sequestration potential.

Authors: Wang Yuexin , Tang Ningkai , Duan Zhixin , Zhang Yu , Yuan Yifei , Liu Yan , Yu Shuo , Liu Ziyuan , Chen Yueguo 
Published: November 2024

Purpose
To compare the subjective refraction and Innov-Eyes (Alcon Laboratories, Inc) wavefront-measured refraction in patients with myopia and astigmatism before refractive surgery.

Methods
Consecutive myopic patients planning to receive refractive surgery with ages between 18 and 50 years old were retrospectively enrolled. The subjective and wavefront-measured refraction (InnovEyes platform) were compared, and the influential factors for the measurement difference were analyzed.

Results

Of the 500 eyes enrolled, the mean age was 29.3 ± 6.8 years. Mean wavefront-measured refraction was 0.58 ± 0.62 diopters (D) more myopic and 0.10 ± 0.27 D more astigmatic than subjective refraction (
P
< .001). Wavefront-measured refraction exhibited excellent consistency and significant correlation with subjective refraction. Linear regression demonstrated that age (
P
= .008) and wavefront-measured sphere standard deviation (
P
< .001) were positively correlated with spherical measurement difference, and total quality score (
P
< .001) and accommodative response (binocular cross-cylinder) (
P
= .011) demonstrated a negative correlation with spherical and cylindrical measurement difference. The patients with low wavefront measurement quality had significantly greater spherical differences than those with high-quality measurement (
P
< .001). The patients with accommodative lead had greater spherical equivalent differences than other participants (
P
= .047).

Conclusions
Wavefront-measured refraction had excellent consistency with subjective refraction, although it measured more myopia and astigmatism than subjective refraction. The spherical measurement difference was greater in older patients and those with accommodative lead. More stable and higher quality repeated measurements will yield closer results between wavefront-measured and subjective refraction.

Inclination des consommateurs à payer pour des légumes frais sans pesticide en Côte d’Ivoire
Authors: Djezou Wadjamsse Beaudelaire , Aba Atsé Éric Noel , Audibert Martine 
Published: November 2024

L’objectif de cet article est d’analyser les préférences des ménages en matière de consommation de légumes en Côte d’Ivoire. Les auteurs utilisent une approche inspirée du modèle hédonique sous la forme d’un modèle Tobit de type 2 appliqué à un échantillon de 366 consommateurs-ménages tirés de façon aléatoire dans la ville de Bouaké et interrogés en 2019. Les résultats montrent que les attributs intrinsèques des légumes influencent positivement les préférences des consommateurs à l’achat. Par ailleurs, la nature bio du légume augmente le prix que les consommateurs sont prêts à payer, révélant leur préférence pour des légumes issus d’une agriculture sans pesticides d’origine chimique. Dès lors, des actions en faveur de la promotion d’une agriculture biologique doivent être encouragées.
La résilience : facteurs de risque et facteurs de protection dans l’environnement social et scolaire du jeune enfant
Authors: Terrisse Bernard , Larose François , Lefebvre Marie-Louise 
Published: November 2024

Dans cet article, les auteurs présentent tout d’abord l’évolution du construit de résilience, à la fois selon ses fondements épistémologiques et sous l’angle du rapport contextuel existant entre le concept de risque et celui de protection. La perspective adoptée, de type écosystémique, implique pour les auteurs de considérer la labilité du construit de résilience en fonction de la nature dynamique du rapport entre l’individu et son environnement. Cette nature dynamique est, à son tour, abordée sous l’angle de la genèse du développement, dans une perspective constructiviste, impliquant la double nature potentielle de chaque variable environnementale. Ils présentent ensuite les résultats d’une étude de résilience réalisée auprès d’un échantillon de 134 élèves provenant de milieux socio-économiquement faibles et ayant bénéficié de mesures d’intervention éducative précoce en 1992-1993. L’étude s’attache à identifier la structure des interactions entre variables reliées aux parents et variables reliées aux enseignants, déterminant ainsi une structure de facteurs de résilience relativement stable. Les auteurs concluent en soulignant l’importance de mener des études de type interdisciplinaire et longitudinal, auprès d’échantillons importants sur le plan numérique, si on désire comprendre de façon contextuelle les interactions complexes entre facteurs favorisant l’adaptation scolaire et sociale des enfants confrontés à des circonstances adverses.
Effects of Exercise Interventions on Cardiac Structure, Function, and Mechanics in Individuals with Chronic Motor-Complete Spinal Cord Injury: An Exploratory Randomized Clinical Trial
Authors: Balthazaar Shane J.T. , Nightingale Tom E. , Alrashidi Abdullah A. , Currie Katharine D. , Krassioukov Andrei V. 
Published: November 2024

Background:
Individuals with spinal cord injury (SCI) at or above T6 face increased cardiovascular disease (CVD) risks due to altered autonomic control and physical inactivity. Arm cycle ergometry training (ACET) or body weight-supported treadmill training (BWSTT) may improve cardiovascular health, but the impact on cardiac structure and function remains unclear.

Objectives:
The study aimed to compare the impact of two exercise interventions on cardiac measures in individuals with chronic SCI.

Methods:
Participants with motor-complete SCI (C4-T6, American Spinal Injury Association Impairment Scale [AIS] grade A or B) were randomly assigned to perform 72 ACET or BWSTT sessions. Left ventricular (LV) echocardiography assessments were performed pre and post training. Data were analyzed using a two-way repeated measures analysis of variance and effect sizes (Cohen’s d).

Results:
Twelve participants underwent analysis (6 per group), revealing significant Group (ACET, BWSTT) x Time (pre, post) interactions for global circumferential systolic and diastolic strain rate (SR) and early diastolic filling velocity (p ≤ .018; Cohen’s d &gt; .8/ -.8). Within-group post hoc testing demonstrated a significant decrease in global circumferential systolic SR (p &lt; .001, d = -4.00) and a significant increase in global circumferential diastolic SR (p = .025, d = 2.48) following ACET, with no significant differences following BWSTT. Although there were no statistically significant within-group post hoc changes (p &gt; .58) for diastolic filling, there was a large effect size favoring ACET (d = 1.11).

Conclusion:
This exploratory study suggests that ACET alters LV mechanics and potentially diastolic function in a cohort of individuals with chronic, cervical or upper thoracic, motor-complete SCI. Conversely, no significant changes were observed following BWSTT. These findings indicate that ACET can improve cardiac function relative to BWSTT in individuals with SCI, though further studies are warranted.
