Published: February 2025

Aims: To explore the relationship between plant communities and key environmental drivers in the Andes of northwest Patagonia, Argentina, and to evaluate the applicability of traditional phytosociological definitions to this region. Methods: We conducted 141 vegetation samples using a stratified systematic sampling design. This was done along two steep gradients of aridity and temperature, which are further modified by local factors that include successional changes due to fire and soil variation. We employed a series of multivariate approaches, including hierarchical clustering, Indicator Species Analysis (ISA), restricted Monte Carlo permutation tests, and both constrained and unconstrained ordinations, to identify (a) the main plant community types, (b) their representative species, and (c) the primary drivers of variation in species composition. Finally, we compared the obtained groups and species to associations described by earlier expert-based classifications. Results: From the set of analyses, we identified six different plant community types with 241 recorded species. We found significant differences across communities’ species composition and their environmental indicators. Among the considered environmental variables, elevation and annual precipitation had the strongest effect on species composition. Additionally, variation in composition was significantly related to forest structure, land use and soil characteristics. We further outlined the influence of locally biased classifications based on a predominance of sampling in areas western to the Andes in classification systems developed in the region. Conclusion: Our analysis allowed us to identify the most relevant environmental drivers and indicator species of the six classified plant communities based on numerical methods. The findings highlight the importance of considering full ecological gradients and communities’ responses for developing stable classification approaches.

Authors: Yu Ke , Liang Tianxing , Chen Ruishan , Tao Wuhai 
Published: February 2025

Purpose
To explore how social media affects older adults' subjective well-being (SWB) through underlying mechanisms.

Method
Path analysis was performed with 106 Chinese older adults to examine the effects of social media's interactive communication, information acquisition, and leisure and entertainment on SWB via social support, self-efficacy, and depressive symptoms.

Results

The model fit well (χ
2
/
df
= 5.28, goodness of fit index = 0.86). Social support mediated the positive relationship between interactive communication and SWB, and self-efficacy mediated the positive relationship between information acquisition and SWB. Leisure and entertainment activities on social media showed no significant association with SWB.

Conclusion

Social media addresses social support deficits from physical limitations and enhances self-efficacy through information retrieval, thus improving SWB. Findings elucidate how social media influences SWB in older adults, offering theoretical guidance for interventions to enhance their well-being. [

Authors: Safwat Abdallah , Abdullah Mohamed , Abdelhalim Ahmed Shawkat , Hassanien Rabei , Mourad Khaled , Moustafa Mohamed Tarek 
Published: February 2025

Background and Objective
This study evaluated the use of a dual-delivery methotrexate (MTX) strategy for diabetic tractional retinal detachment (TRD). Diabetic retinopathy (DR) is a leading cause of blindness. Inflammation plays a key role in TRD, and MTX has anti-inflammatory properties.

Patients and Methods

This is a pilot study that included 60 patients with TRD. They were block randomized to either MTX with pars plana vitrectomy (PPV) (
n
= 30) or PPV alone (control,
n
= 30). MTX was added to the irrigation fluid during surgery and an intra-silicone injection at the end. One month after silicone oil removal, visual acuity (VA), multifocal electroretinography (mfERG), and spectral-domain optical coherence tomography (SD-OCT) were assessed.

Results
One month after silicone oil removal, VA and mfERG were significantly better with a lower prevalence of epiretinal membranes, disorganization of retinal inner layers, and cystic macular changes by SD-OCT in the MTX group.

Conclusion
This study found that dual-delivery MTX during PPV is a promising strategy to improve functional and anatomical results in diabetic TRD.

Développant quelques propositions formulées par des chercheurs proches de Roger, ce numéro ouvre de nouveaux chemins d’enquête et contribue ce faisant à la reconstitution du panorama intellectuel de l’histoire et de la philosophie des sciences en France dans la seconde moitié du xxe siècle.
Sur l’intérêt de Roger pour Malebranche. De la littérature à l’histoire des sciences
Authors: Ferraro Angela 
Published: February 2025

Nous nous proposons d’explorer le lien qui existe entre la formation littéraire de Jacques Roger et sa carrière d’historien des sciences de la vie. Pour atteindre cet objectif, nous nous pencherons sur les pages qu’il a consacrées à Nicolas Malebranche, notamment dans son article « L’expression littéraire chez Malebranche » (1967) et dans son célèbre ouvrage Les sciences de la vie dans la pensée française au xviiie siècle (1963). À la fois maître de style et savant de premier ordre, l’oratorien réunit dans son profil intellectuel deux des principaux objets d’intérêt de Roger. Y a-t-il de bonnes raisons de supposer que ce dernier entretint un rapport privilégié avec l’œuvre malebranchiste ? Dans cette contribution, nous essayerons de donner une réponse à cette interrogation.

Published: February 2025

Background: The primary and secondary vectors for dengue, Aedes aegypti Linnaeus and Aedes albopictus Skuse, necessitate rigorous vector surveillance to understand real-time vector population dynamics. While larval surveys are commonly employed, they alone do not adequately predict the risk of dengue transmission. The ovitrap survey is a useful technique that has demonstrated effectiveness in dengue control programs as a sur-veillance component; however, it is underutilized in dengue risk determination. Hence, it is crucial to assess their use in monitoring disease morbidity and forecasting dengue risk to prevent epidemics in dengue risk localities. General Objective: This study evaluated Aedes ovitap surveillance data with disease surveillance data to assess the dengue transmission risk in selected localities in the Kegalle district.Methods: Ovitrap surveillance was conducted monthly, from January 2023 to December 2023, in three high-risk localities in selected high-risk Medical Officer of Health (MOH) areas, namely, Mawanella, Dehiovita, and Warakapola. In each locality, a total of 100 stranded ovitraps were placed, 50 indoors and 50 outdoors, collect-ed after five days, and examined for emerging larvae. Confirmed dengue case data were obtained from the web-based disease surveillance system, DENSYS, of the Ministry of Health, Sri Lanka. The Mean Egg Cup Density (MECD), Egg Hatched Rate (EHR), and Larval Count (LC) of Ae. aegypti and Ae. albopictus indoors and outdoors was measured for each MOH area. Their combined effects were analyzed using General Linear Model (GLM) ANOVA. The correlations between dengue cases and MECD, EHR, and LC for both mosquito species were tested using Spearman’s rank correlation.Results: Significant differences in MECD were observed between months (P=0.006), MOH (P<0.05), and Trap Placement (TP) (P=0.05). For MECD, there were significant influences from the com-bined effects of month*MOH (P<0.05) and MOH *TP (P=0.05). LC was also significantly affect-ed by MOH (P<0.05), mosquito species (P<0.05), and the interaction of TP with mosquito species (P<0.05 The mean number of dengue cases showed significant correlations with the MECD (P=0.020 and LC of Ae. albopictus (P=0.011), Indoor EHR (P=0.013), and Outdoor EHR (P = 0.017). Conclusion: The positive relationship between the outcome of the ovitrap surveillance data and the dengue case data highlights the importance of integrating both datasets to monitor dengue morbidity and Aedes populations as well as to effectively forecast dengue epidemics in dengue high-risk localities.

Authors: Mohymen Ahmed Abdel , Farag Hamed Ibrahim , Reda Sameh M. , Monem Ahmed Soltan , Ali Said Abdelfattah 
Published: February 2025

Abstract

Aim:
This study aimed to optimize the quantitative aspects of (18F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) imaging by investigating the impact of various reconstruction parameters on the recovery coefficients (RCs) using the NEMA image quality phantom. Specifically, the study aims to assess how different matrix sizes, iterations, subsets, and Gaussian postfilters affect the accuracy of standardized uptake value (SUV) quantification in (18F) FDG PET/CT imaging.

Materials and Methods:
The study utilized the “Vue Point FX + Sharp IR” algorithm for PET image reconstruction, incorporating 3D-ordered subset expectation maximization (3D-OSEM), time-of-flight, and point spread function technologies. Various reconstruction parameters were explored, including two distinct matrix sizes, multiple iterations, subsets, and a wide range of Gaussian postfilters. The investigation focused on the impact of these parameters on RCs using the NEMA image quality phantom.

Results:
The results of the study indicated that for accurate SUV quantification in spheres ≥17 mm, the 256 × 256 matrix size and mean SUV should be employed. Conversely, for spheres ≤13 mm, maximum SUV was found to be more suitable. The choice of postfiltering value was shown to have a significant impact on SUV quantification accuracy, particularly for small-sized spheres. In addition, a larger matrix size was found to partially mitigate the effects of Gibbs artifact and slightly enhance SUV quantification for the spheres of various sizes.

Conclusion:
This study highlights the critical importance of optimizing PET reconstruction parameters in accordance with the guidelines set by European Association of Nuclear Medicine/EARL. By optimizing these parameters, the accuracy and reliability of SUV quantification in (18F) FDG PET imaging can be significantly enhanced, especially for small-sized spheres. This underscores the necessity of carefully considering reconstruction parameters to ensure precise and reliable quantitative measurements in PET/CT imaging.

Published: February 2025

ABSTRACT

Objective:
To evaluate the clinical and radiographic effects of ellagic acid on osseointegration around dental implants.

Materials and Methods:
A total of 60 patients, aged between 25 and 55 years, requiring dental implants, were designated for the study. They were randomly divided into two sects: The experimental group (30 patients) received dental implants with ellagic acid, and the control group (30 patients) received dental implants without ellagic acid. The peri-implant pocket depth, implant stability, and gingival index were recorded. Radiographic analysis was conducted to measure bone density and marginal bone loss around the implants at 3-, 6-, and 12-months post-implantation.

Results:
The experimental group showed significantly higher implant stability and bone density compared to the control group at all time points (P < 0.05). The peri-implant pocket depth and gingival index were lower in the experimental group, indicating better periodontal health. Radiographically, the experimental group demonstrated less marginal bone loss compared to the control group.

Conclusion:
Ellagic acid enhances osseointegration around dental implants, resulting in improved clinical outcomes and reduced marginal bone loss.

ABSTRACT

Introduction:
Oral precancerous lesions, such as leukoplakia and erythroplakia, are significant contributors to the global burden of oral cancer. Understanding their epidemiology, incidence, and progression is essential to early detection and prevention. In India, these lesions are prevalent due to widespread tobacco consumption and other lifestyle factors, leading to an increased risk of oral cancer development.

Methods:
A prospective observational study was conducted with 150 patients showing clinical signs of oral precancerous lesions. Three parameters were analyzed: patient demographics, lesion characteristics, and risk factor associations. Incidence and progression data were statistically analyzed using appropriate tests.

Results:
Our study identified key demographic groups at higher risk, with significant lesion progression in specific subpopulations. Statistical analysis showed strong associations between tobacco use and lesion development, consistent with previous studies.

Conclusion:
This study highlights the incidence and progression of oral precancerous lesions and their significant correlation with risk factors, emphasizing the need for early intervention strategies.

Authors: Kondreddy Kameswari , Mohanty Aishwarya , Desai Vishwa , Surekha Gadisetti Lakshmi , Khader Anas Abdul , Mathur Suveet , Shetty Smitha 
Published: February 2025

ABSTRACT

Introduction:
Nonsurgical periodontal treatment, particularly scaling and root planing (SRP), is essential for managing periodontitis. Adjunctive systemic antibiotics have been proposed to enhance the clinical outcomes of SRP, especially in advanced stages of the disease. This systematic review evaluates the effectiveness of adjunctive systemic antimicrobial therapy on clinical parameters, including probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing (BOP).

Methods:
A systematic search of PubMed was conducted, focusing on randomized controlled trials (RCTs) between 2010 and 2024 that evaluated the use of systemic antibiotics as an adjunct to SRP in patients with stage III/IV periodontitis. The primary outcomes assessed were changes in PPD, CAL, and BOP.

Results:
Forty-eight studies, including three recent trials, were analyzed. The combination of amoxicillin and metronidazole resulted in significant improvements in clinical outcomes, with notable reductions in PPD and CAL. Two tables summarize these findings.

Conclusion:
Systemic antibiotics, especially amoxicillin and metronidazole, significantly enhance clinical outcomes when used adjunctively with SRP. Shorter antibiotic regimens may provide similar benefits with fewer side effects.

Published: February 2025

ABSTRACT

Introduction:
The choice between implant-supported overdentures and conventional complete dentures plays a significant role in patient satisfaction and functional outcomes. Implant-supported overdentures are increasingly used due to their stability, comfort, and improved chewing efficiency. This study aims to evaluate the differences in patient-reported satisfaction and functional outcomes between these two types of prostheses.

Methods:
A cohort of 150 edentulous patients was evaluated using either implant-supported overdentures or conventional complete dentures. Patients completed a satisfaction questionnaire, and masticatory function was assessed through standardized masticatory performance tests. Data were analyzed using descriptive statistics and comparative analysis.

Results:
Patients with implant-supported overdentures reported significantly higher satisfaction, particularly in comfort, stability, and chewing ability. Masticatory efficiency was also notably better in the implant group. However, conventional dentures showed adequate results in terms of cost and accessibility.

Conclusion:
Implant-supported overdentures offer superior satisfaction and functional outcomes compared to conventional complete dentures, making them a preferred option for long-term edentulous rehabilitation.
Bilateral peripheral ulcerative keratitis in a child with juvenile idiopathic arthritis
Authors: Siddiqui Alma , Kumari Reena , Bhagat Dinesh Kumar 
Published: February 2025

Abstract
Peripheral ulcerative keratitis (PUK) is characterized by epithelial destructive lesions in the perilimbal cornea causing corneal thinning. It is an inflammatory condition commonly associated with systemic autoimmune disorders and mainly found in middle-aged females. It is a sight threatening entity with potential for severe visual impairment or loss of eye. Recognition of ocular manifestations of PUK is essential especially in the younger age group, as it is difficult to diagnose in a child. We present a unique case of a 13-year-old girl with bilateral PUK and later diagnosed with juvenile idiopathic arthritis. She was started on methotrexate tablets to control the systemic disease and advised continuation of topical cyclosporine eye drops.
Vision loss following orbital cellulitis complicated by acute dacryocystitis: Report of a rare case with review of literature
Authors: Alam Md. Shahid , Paul Pragati , Sharma Survee , Desai Janhavi 
Published: February 2025

Abstract
A 59-year-old diabetic woman presented with acute dacryocystitis in her left eye and visual acuity of finger counting at two feet and was initially treated with topical and systemic antibiotics. However, her condition deteriorated, leading to left orbital cellulitis and a significant reduction in vision, with no perception of light. Prompt drainage of the lacrimal abscess was performed, and she was administered parenteral antibiotics. The patient showed clinical improvement and subsequently underwent external dacryocystorhinostomy after the acute infection had subsided. Unfortunately, her visual acuity did not improve significantly, with only a positive perception of light. Magnetic resonance imaging during the acute phase revealed optic nerve enhancement and focal signal changes, which persisted even after the infection had resolved. Acute dacryocystitis rarely advances to orbital cellulitis, which can result in vision loss, with only a few documented cases in literature. It is crucial to closely monitor such patients and promptly intervene with imaging and parenteral antibiotics, along with abscess drainage if indicated.
Contact lens-related keratitis due to an emerging pathogen Alcaligenes faecalis

Published: February 2025

Abstract
This case report highlights a rare case of contact lens-related keratitis (CLRK) caused by the emerging pathogen Alcaligenes faecalis, which underscores the growing diversity of microorganisms implicated in ocular infections. A 28-year-old female, who had been using yearly disposable contact lenses (CLs) for the past 8 years without prior complications, developed peripheral corneal infiltrates. The infiltrates were attributed to the chronic use of CLs. Corneal scraping and CL culture results identified A. faecalis as the causative organism, a rare and novel cause of keratitis in CL users. The patient was treated promptly with broad-spectrum topical antibiotics, leading to a full resolution of the infiltrates. This is likely the first documented case of CLRK caused by A. faecalis. While A. faecalis belongs to the Pseudomonadaceae family, it did not manifest as a typical aggressive infection, suggesting a potentially less virulent course in CLRK. This case adds to the growing awareness of nonconventional pathogens in ocular infections and highlights the importance of early detection and treatment to prevent more severe outcomes.
