ABSTRACT

Background: Incisional hernia is a common complication following abdominal surgery, and mesh reinforcement has become

the standard of care. This study aimed to compare the clinical outcomes of sublay versus onlay mesh repair in patients with

incisional her

nia.

Methods: This prospective randomized controlled clinical trial was conducted at the General Surgery Department, Faculty

of Medicine, ..... Hospitals. A total of 60 patients diagnosed with incisional hernia and scheduled for elective surgical repai

r

were recr

uited from general surgery outpatient clinics and the emergency department. Patients were randomly assigned into

two equal groups: Group A (Onlay Group, n=30) underwent onlay mesh repair, and Group B (Sublay Group, n=30)

underwent sublay (retrorectus) mesh

repair. Baseline demographic, clinical, laboratory, and radiological characteristics were

recorded. Operative parameters, postoperative pain scores (Visual Analogue Scale), hospital stay, return to normal activity,

postoperative complications (seroma, hem

atoma, surgical site infection), and hernia recurrence at 12 months were compared

between the two groups.

Results: Operative time was significantly shorter in the onlay group (88.93 ± 7.93 minutes) compared to the sublay group

(99.67 ± 7.74 minutes) (p < 0.001). Postoperative pain scores were significantly lower in the sublay group at day 1 (4.70 ±

0.76 vs. 6.

10 ± 0.79), 1 week (2.39 ± 0.75 vs. 3.99 ± 0.82), 1 month (0.85 ± 0.74 vs. 2.41 ± 0.88), 3 months (0.30 ± 0.49 vs.

1.41 ± 0.86), 6 months (0.16 ± 0.36 vs. 1.02 ± 0.82), and 12 months (0.14 ± 0.48 vs. 0.82 ± 0.86) (p < 0.001 for all). Hospit

al

stay was sign

ificantly shorter in the sublay group (3.47 ± 1.11 days vs. 4.40 ± 0.93 days, p < 0.001), and return to normal

activity was significantly earlier (21.53 ± 3.41 days vs. 26.07 ± 4.73 days, p < 0.001). No significant difference was found

in drain removal day

(p = 0.257). Postoperative complications including seroma (10.0% vs. 23.3%, p = 0.299), hematoma

(3.3% vs. 6.7%, p = 1.000), and surgical site infection (6.7% vs. 16.7%, p = 0.424) were directionally lower in the sublay

group but did not reach statistical

significance. Hernia recurrence at 12 months was 3.3% in the sublay group versus 10.0%

in the onlay group (p = 0.612). All patients completed the 12

-

month follow

-

up.

Conclusion: Sublay (retrorectus) mesh repair offers significant clinical advantages over onlay mesh repair for incisional

hernia, including superior postoperative pain control, shorter hospital stay, and earlier return to normal activity. Postoper

ative

com

plications and recurrence showed consistent trends favoring sublay repair. These findings support sublay mesh repair as

the preferred technique for elective incisional hernia repair in appropriately selected patients.

• Several types of steroids are a class of medications used worldwide to treat pain. Despite significant differences in their use across various age groups, particularly among young people, including university students, steroids offer a significant health benefit when used without a prescription and with guidance from a pharmacist. 425 new Libyan students from various colleges in Gharyan University (Medicine, Pharmacy, Science, Arts, etc.). The data were collected using a structured self-designed questionnaire consisting of 32 items. Descriptive (frequencies and percentages) and inferential statistics (Cronbach's alpha coefficient) were applied to assess internal consistency, and the Chi-squared test and ANOVA. The analysis revealed that 90.4% of students do not use non-steroidal anti-inflammatory drugs for pain, 94.1% do not use them for headaches, and 94.6% do not use them without a prescription. 6.1% reported experiencing stomach pain after use, and 1.6% indicated that they needed a larger dose to achieve the same effect. The Cronbach's alpha coefficient was 0.81, indicating good internal consistency. This study found significant differences in eight question items (29.6%) between genders and in three items between age groups. Thus, students at Gharyan University have a high level of awareness regarding the safe use of non-steroidal anti-inflammatory drugs and avoiding their use without a prescription.

ABSTRACT

The fatigue behavior of 2024 aluminum alloy is strongly influenced by heat treatment conditions, particularly T6 and retrogression and re-ageing (RRA) processes. In this study, specimens obtained from 2024 alloy plates were solution heat-treated at 520°C /2 h and subsequently aged to the T4 condition at 120°C/24 h. All samples were then subjected to a natural ageing (shelf life) period of 15 days before undergoing retrogression at approximately 220°C/3 min, followed by re-ageing at 165°C for 2h. The heat-treated samples were evaluated using tensile testing, electrical conductivity in %IACS and high cycle fatigue testing after all proposed heat treatment cycles. The samples were further tested under high-cycle fatigue conditions. The results indicate that both tensile properties and electrical conductivity were adversely affected after the 15-day shelf life. Distinct differences in fatigue behavior were observed between the retrogression and T6 (re-ageing) treated alloys. The retrogression treatment for a short time for the samples after 15 days, exhibited an improvement of mechanical strength and electrical conductivity. However, re-aging of these samples for 165/2hr shows beak strength with decrease in electrical conductivity. Although, T6 condition provides superior strength, the Retrogression treatment offers high fatigue performance by improving crack growth resistance, making it a more suitable choice for applications requiring enhanced fatigue durability.

The present study aimed to assess the knowledge of diabetic patients regarding diabetes-related systemic and oral

complications and to evaluate their attitudes toward maintaining good oral health and their oral hygiene practices,

including regular dental visits. A cross-sectional study was conducted at Gharyan Educational Hospital, Gharyan,

Libya, between November 2025 and January 2026. A total of 134 diabetic patients attending scheduled outpatient

clinics were enrolled. The study found that 60.5% of participants were aware that diabetes increases the risk of

oral disease, with a high awareness of xerostomia (91%). However, knowledge of specific complications was lower;

only 46.2% identified dental caries and 42.6% identified oral fungal infections as related risks. Regarding systemic

health, patients showed higher awareness of diabetic foot and eye complications than of nerve or kidney

complications. While 73.9% of participants reported brushing their teeth, only 41.8% did so twice daily.

Furthermore, 44.8% visited the dentist less than once a year, and 41% could not remember their last visit. The

primary sources of information were diabetologists (52.9%) and various media (50%), with 98.5% of participants

expressing a desire for more education on this topic. Diabetic patients in Gharyan demonstrated a moderate level

of knowledge regarding diabetes-related oral health. While attitudes toward oral hygiene are generally positive,

there are significant gaps in knowledge regarding specific oral complications. The findings suggest an urgent need

to integrate oral health education into routine diabetic care and to strengthen collaboration between physicians and

dentists to improve overall patient outcomes.

This study reports on a collection of spiders from Misallatah Nature Reserve and National Park (MNRNP), north western Libya, including five species recorded for the first time in the country. 75 spider samples (13 adult males, 20 adult females, 42 juveniles), comprising 12 families (Agelenidae; Araneidae; Dysderidae; Gnaphosidae; Lycosidae; Palpimanidae; Pisauridae; Philodromidae; Pholcidae; Salticidae; Thomisidae; Zodariidae), 13 genera (Lycosoides Lucas, 1846; Argiope Audouin, 1826; Dysdera Latreille, 1804; Nomisia Dalmas, 1921; Hogna Simon, 1885; Palpimanus Dufour, 1820; Holocnemus Simon, 1873; Aelurillus Simon, 1885; Menemerus Simon, 1868; Plexippus C. L. Koch, 1846; Phlegra Simon, 1876; Bassaniodes Pocock, 1903; Zodarion Walckenaer, 1826) and 13 species (Argiope lobata Pallas, 1772; Dysdera crocata C. L. Koch, 1838; Nomisia recepta Pavesi, 1880; Palpimanus gibbulus Dufour, 1820; Holocnemus pluchei Scopoli, 1763; Plexippus paykulli Audouin, 1826; Bassaniodes lalandei Audouin, 1826; Zodarion pileolonotatum Denis, 1935; Lycosoides flavomaculata Lucas, 1846; Hogna effera O. Pickard-Cambridge, 1872; Aelurillus blandus Simon, 1871; Menemerus taeniatus L. Koch, 1867; Phlegra yaelae Prószyński, 1998) were collected; the last five species are first records in Libya.

The volume of Arabic text online keeps growing, and with it the need for systems that sort it into meaningful categories. A quieter problem often passes unnoticed: when long documents are split into shorter segments and pieces of the same document fall on both sides of the boundary between training and testing, the reported scores can look far better than the model deserves. This study treats that document level leakage as its central subject. Using a purpose built multidomain Arabic corpus of 1,000 segments drawn from 183 source documents across seven categories, we first measure how much leakage distorts the numbers. Under a naive random split, an optimized Linear SVM appears to reach 0.9800 accuracy; under a grouped split keyed to the document identifier, the same model reaches 0.8528. The gap of about 12.7 accuracy points is attributable to leakage, and across models the inflation ranges from roughly 11.9 to 30.4 points. Leakage also flattens the ranking, so a weak Naive Bayes looks almost as strong as the best model. Under the honest protocol, an ablation shows that character level TF IDF alone matches the combined word and character representation and slightly exceeds it on Macro F1, 0.7801 against 0.7713, while word features mainly refine precision. McNemar tests and a document clustered bootstrap show that the strongest linear models are statistically indistinguishable. A fastText baseline reaches 0.6497 accuracy, and two pretrained Arabic transformers, AraBERT and MARBERT, perform comparably to the linear model rather than surpassing it. A class level analysis exposes the General category as a structural confound whose removal raises accuracy to 0.9349. Overall, leakage aware evaluation paired with subword rich TF IDF and a Linear SVM forms a strong, honest, and practical baseline for Arabic text classification.

Abstract

This study investigates applying the artificial intelligence tools in translating culture-specific items in literary works. A heated debate has been initiated among scholars since the beginning of using AI tools in translation; the core of this debate was about the ability of AI translation tools to convey cultural nuances compared to human translators. Furthermore, techniques are usually adopted by AI translators in case of a lack of equivalence. To investigate these queries, fourteen excerpts containing cultural elements have been chosen from three Libyan novels by Ibrahim Al-Koni, The Bleeding of the Stones, Dust Gold and Anubis, are utilized as a case study to compare the human translator's work with AI translation tools, namely, ChatGPT and DeepL. The major results of this study are the performance of AI tools almost the same as human translators. Although AI translation tools outperformed human translators' work in some situations, they still require specialized training on culture-specific items related to specific communities. A collaboration between human and AI tools results in significant translation rather than separating or substituting each other. The mixing between machine and human leads to important progression in the field of translation.
