Spider species distribution in the Cape Floristic Kingdom (CFK) was compiled as part of the South African National Survey of Arachnida (SANSA), whose main aim was to create a relational database for the country's arachnid fauna. Data from the CFK was extracted from taxonomic and faunistic published papers, as well as unpublished faunistic survey data in national collections. A total of 11 500 records from 130 localities were recorded in the CFK until the end of 2023, representing 62 families, 334 genera and 960 species, with two further families (Synotaxidae and Theridiosomatidae) only known from undescribed species. This represents 42.4% of the total spider fauna of South Africa. For each species, the global and CFK distribution, as well as the level of endemicity and a conservation assessment using the IUCN Red List criteria, are provided. A total of 269 spp. (28.0%) are endemic to the CFK, 49 spp. (5.1%) are of special concern, and 229 spp. (23.9%) are Data Deficient. However, most of the species (682 spp., 71.0%) have a wide distribution with no known threats and are categorised as Least Concern. Salticidae is the most species-rich family (128 spp.), with 30 spp. endemic to the CFK, followed by the Gnaphosidae (107 spp.), Thomisidae (86 spp.) and Lycosidae (49 spp.), while six families are represented by a single species. The last decade has seen an exponential growth in the knowledge of spiders in South Africa, and there are certainly many more species that must still be discovered and described.

Introduction: Infection is a significant complication of cardiac implantable electronic device (CIED) therapy. The European TauroPace™ Registry investigates the safety and efficacy of TauroPace™ (TP), an antimicrobial solution containing taurolidine, designed to prevent CIED infections., Methods: This multicenter study included patients undergoing CIED procedures at participating centers where TP was used as a disinfectant for external hardware surfaces and an antiseptic for irrigating surgical sites. All patients eligible for CIED placement with adjunctive TP as the standard of care were included. Other aspects of CIED procedures adhered to current guidelines. Data on CIED-related infective endocarditis, CIED pocket infection, device and procedure-related complications, adverse events, and all-cause mortality were prospectively collected for 12 months. In cases of revision, the previous procedure was censored, and a new procedure was created. Binomial and Kaplan-Meier statistics were employed to analyze event rates., Results: From January 2020 to November 2022, TP was used in 822 out of 1170 CIED procedures. Among patients who completed the 3-month follow-up, no CIED pocket infections were observed, and one case of CIED-related infective endocarditis was reported. In the 12-month follow-up cohort, two additional local pocket CIED infections were observed, resulting in a total of three major CIED infections within 1 year after the CIED placement procedure. The 3-month and 12-month major CIED infection rates were 0.125% and 0.51%, respectively. During the observation a complication rate of 4.4% was reported. No adverse events related to TP were observed., Conclusions: TP appears to be effective and safe in preventing CIED infections., Clinicaltrials: gov Identifier: NCT04735666., (© 2024.

Background: The United States Food and Drug Administration (FDA) recommends silicone breast implant rupture surveillance using MRI or ultrasound beginning at 5-6 years post-insertion and every 2-3 years thereafter. No surveillance guidelines exist in Canada or the UK. This study aims to identify surveillance practices and perceived barriers to surveillance among plastic surgeons in Canada and the UK and compare surgeon practices between public and private sectors., Methods: All active members of the Canadian Society of Plastic Surgeons (CSPS) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) with an interest in breast surgery were surveyed. Surgeon demographics, screening practices and perceived barriers to screening were analyzed. Fisher's exact test was used to detect significant associations., Results: The survey response rate was 16%. Most surgeons (68%, n=58/85) were familiar with FDA guidelines; however, only 2.4% (n=2/85) followed them. Surgeons in private practice screened significantly more than surgeons in the public sector [45% (n=13/29) vs 13% (n=7/56), p<0.002]. Among surgeons, ultrasound and high-definition ultrasound were the most common screening modalities and a perceived lack of clinical necessity followed by a perceived lack of satisfactory evidence qualifying these guidelines was the most reported barrier to screening., Conclusion: Despite awareness of FDA guidelines, compliance among surgeons surveyed remains low, reportedly due to a perceived lack of necessity or evidence base. Most public sector surgeons opt not to screen and do not recommend surveillance, even without barriers. While governing bodies should consider current practices to shape guidelines, increasing surgeons' awareness on their evidentiary foundation and potential consequences of silent ruptures is imperative., Level of Evidence V: This journal requires that authors assign a level of evidence to each article.

Objectives: To test the hypothesis that resilience has a mediating effect on the association between work fatigue and psychological distress., Methods: A cross-sectional survey was conducted online in eight countries in 2021: Brazil, Lebanon, Nigeria, Pakistan, Poland, Qatar, Serbia, and Tunisia. A total of 1094 healthcare professionals specialized in medicine, pharmacy, and nurse practitioners that were exposed to/worked with COVID-19 patients were included (age: 33.89 ± 10.79 years; 59.6% females)., Results: After adjusting for potential confounders (i.e., country, gender, primary work in emergency department, primary work in infectious disease, primary work in intensive care unit, working in a COVID-19 ward, and working voluntary hours), the results of the mediation analysis showed that resilience fully mediated the association between physical work fatigue and psychological distress and partially mediated the associations between mental and emotional work fatigue and psychological distress. Higher work fatigue was significantly associated with less resilience; higher resilience was significantly associated with less psychological distress. Finally, higher mental and emotional, but not physical, work fatigue, were directly and significantly associated with more psychological distress., Conclusion: Identifying resilience as an important mediator in the path from fatigue to distress helps elucidate underlying mechanisms and pathways leading to the mental health-alteration process among healthcare workers during COVID-19. New strategies targeting resilience may be developed to further improve mental health outcomes among healthcare workers., Competing Interests: DisclosureThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Food protein-induced enterocolitis syndrome (FPIES) is being increasingly recognized as a non-IgE-mediated food allergy; however, it remains unclear if and how the presentation, diagnosis, and management of this disease has changed in recent years., Objective: To reappraise the FPIES cohort at a large US pediatric tertiary referral center., Methods: We performed a retrospective chart review of pediatric patients with FPIES (International Classification of Diseases, Tenth Revision code K52.21) diagnosed in our allergy/immunology clinics between 2018 and 2022., Results: There were 210 children diagnosed with FPIES. Most were White (73.8%), non-Hispanic (71.4%), and male (54.3%) with private insurance (77.6%). Cow's milk was the most common food trigger (35.2%), with the earliest median age of onset of 5 months. The atypical FPIES rate was 13.8%. FPIES was accurately diagnosed in 54.3% at the first medical contact. The oral food challenge pass rate was 73.5%. The rate of trigger resolution at 36 months was 77%., Conclusions: By comparing trends from a previous and current FPIES cohort, we were able to assess the potential impact of various guidelines and practice changes on the diagnosis and management of FPIES at our center. Milk and oat surpassed rice as the most common FPIES triggers; peanut and egg emerged as new FPIES triggers; there was a shorter time to diagnosis and an increased rate of atypical FPIES. Our findings reflect earlier recognition of FPIES and prompt allergy/immunology referral from community physicians, implementation of recent medical society guidelines for infant feeding practices, and growing clinical expertise of allergists at our center., (Copyright © 2024 The Authors.

Objective: This study aims to identify the association between adherence to healthy eating, using the Lebanese Mediterranean Diet Scale (LMDS), and cardiovascular risk factors in the Lebanese population., Materials and Methods: A cross-sectional study using a multistage cluster sample was conducted in Lebanon. Sociodemographic characteristics were collected through structured interviews and self-administered questionnaires. The LMDS assessed dietary habits. The associations between diabetes, dyslipidemia, and cardiovascular disease were investigated using stratification analysis., Results: The study included 2048 people (mean age: 41.54 ± 17.09 years). Higher adherence to the Mediterranean diet was associated with older age (Beta = 0.175, p < 0.001), being female (Beta = 0.085, p = 0.001), being married (Beta = 0.054, p = 0.047), participating in regular physical activity (Beta = 0.142, p < 0.001), and having cardiovascular disease (Beta = 0.115, p < 0.001) and diabetes (Beta = 0.055, p = 0.043). Adherence was, however, negatively associated with being a smoker (Beta = -0.083, p = 0.002), a previous smoker (Beta = -0.059, p = 0.026), and having higher distress levels (Beta = -0.079, p = 0.002). Stratification analysis by diabetes, dyslipidemia, and cardiovascular disease (CVD) consistently demonstrated these associations., Conclusions: These findings suggest that demographic and health factors influence the Lebanese population's adherence to the Mediterranean diet. Older age, female gender, married status, physical activity, CVD, and diabetes were all found to be associated with adherence to the Mediterranean diet in the Lebanese population. In contrast, smoking and distress were inversely associated with it.

Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy, characterized by delayed onset of repetitive vomiting occurring 1 to 4 h following ingestion of a food allergen. Managing FPIES requires strict avoidance of the food trigger. The concern with FPIES is determining the risk of another FPIES food trigger reaction due to potential coassociations with other foods or food groups. An effective statistical approach for analyzing FPIES-related data is essential to identify common coallergens and their associations., Methods: This study employed Market Basket Analysis, a data-mining technique, to examine correlations and patterns among allergens in FPIES patients at a Houston, Texas, pediatric tertiary center. A retrospective analysis of electronic medical records from January 2018 to March 2022 for allergist diagnosed FPIES patients was conducted. The analysis utilized R software, specifically the "arules" and "arulesViz" packages, implementing the Apriori algorithm with set minimum support and confidence thresholds., Results: The study included 210 FPIES cases over 4 years, with 112 patients reacting to one food trigger and 98 to more than one trigger. In the latter group, the 5 predominant triggers were cow's milk (45.9%), rice (31.6%), oats (30.6%), soy (22.4%), and avocado (19.4%). Market Basket Analysis identified significant associations between food categories, particularly between soy and dairy, egg and dairy, oat and dairy, rice and dairy, and avocado and dairy., Conclusion: Market Basket Analysis proved effective in identifying patterns and associations in FPIES data. These insights are crucial for healthcare providers in formulating dietary recommendations for FPIES patients. This approach potentially enhances guidance on food introductions and avoidances, thereby improving management and the quality of life for those affected by FPIES., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: SA receives research grant funding from NIH/NIAID and DBV.

Background: While previous research underscores the independent effect of the pharmacist-patient relationship on patient outcomes, it did not delve further into the patient-pharmacist relationship dynamics and their effects on reported outcomes. Therefore, this study aimed to assess whether patient-pharmacist relationship aspects mediate the association between patient personal and health characteristics, on the one hand, and adherence to medication and quality of life, on the other hand (QOL)., Methods: An online cross-sectional study was conducted between April 11 and 27, 2023. It enrolled 865 adults from all Lebanese governorates and used validated scales to measure the various concepts., Results: The mean age was 32.52 ± 14.56 years, and 68.8% were female. Also, 79.3% reported having no chronic disease, and 57.7% indicated that getting nonprescription medications was the main reason for visiting a community pharmacy. The average routine intake of medications per day was 0.87 ± 1.78. Our key findings reveal a compelling association between worse health status and both increased medication non-adherence and reduced QOL. Sociodemographic factors were found to be correlated with QOL. Despite the considerable impact of demographic factors on patient expectations, our study challenges the expected mediation role of the pharmacist-patient relationship and counseling time on medication adherence. Nevertheless, patient expectations partially mediated the relationship between sociodemographic characteristics and QOL., Conclusion: This study sheds light on the intricate dynamics between patient characteristics, health status, medication adherence, and QOL within the context of the patient-pharmacist relationships., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2024 The Author(s).

Background: The financial crisis has indirectly affected Lebanese university students, leading to economic distress. Accordingly, this study aimed to assess the substantial negative impact of financial stress on the mental health and well-being of Lebanese college students., Methods: A quantitative research approach was applied and took place from June 13th to July 25th, 2023, targeting 1272 university students aged 17 and above from private and public universities across Lebanon through convenience sampling. The InCharge Financial Distress/Financial Well-Being scale (IFDFW), Pittsburgh Sleep Quality Index (PSQI), Beirut Distress Scale (BDS-10), Perceived Stress Scale (PSS-10), and Well-Being Index (WHO-5) were used to assess the students' well-being. Descriptive analyses of the data was performed using SPSS software version 25., Results: 1272 university students participated in this study, mostly females, with a mean age of 21.64 (± 4.43) years. Participants reported a lack of financial independence, unemployment, and no income. Positive associations were obtained between the BDS total scale as well as the PSS total and PSQI scores, while there was a significant negative relationship between IFDFW and PSQI scores. Those with a higher GPA, majoring in science/health and medicine, living in rural areas, and graduate students were linked to lower PSQI and BDS-10 scores. Financial aid and financial independence were associated with lower PSQI and BDS-10 scores. PSS-10 scores were higher among students majoring in science/health and medicine. Higher scores on the IFDFW scale correlated with lower BDS-10 and PSS-10 scores. In contrast, females had higher BDS-10 and PSS-10 scores. Scoring higher on the PSS-10 and PSQI scales, living off campus, or majoring in science/health and medicine, were associated with higher on the WHO-5 scale., Conclusions: A significant impact of financial stress on college students in Lebanon was obtained, affecting their well-being and mental health aspects. Marital status, gender, academic major, region of living, and financial independence also influences students' experiences. Tailored support and further research are needed to address these multifaceted challenges., (© 2024. The Author(s).)

Purpose: While horizontal strabismus surgery is generally considered to have favorable outcomes, success rates can vary by type of procedure. Our purpose is to compare the long-term outcomes of patients who underwent one-muscle vs. two-muscle horizontal strabismus surgery., Methods: This is a retrospective study comparing one-muscle to two-muscle strabismus surgery for small to moderate angle horizontal strabismus. Demographic data and eye exam parameters were compared at baseline and postoperatively (6 months up to 6 years). Surgical success was defined as a post-operative angle of 10 PD or less. We also compared outcomes by strabismus type: esotropia vs exotropia and adjusted the analysis for previous strabismus surgery., Results: Out of 89 patients with moderate angle horizontal strabismus (25 PD or less), 17 patients had a one-muscle operation, and 72 patients had two-muscle surgery. The mean age was 14.12 ± 9.30 years and 11.70 ± 11.30 years for the one-muscle and two-muscle groups, respectively ( p  = .74). The baseline characteristics of both groups were comparable. Follow-up time was 32.82 ± 26.93 months in one-muscle and 37.67 ± 23.81 in two-muscle groups ( p  = .29). Success rate was 70.6% for the one-muscle group and 68.10% for the two-muscle group ( p  = .69). Outcomes were similar when divided into esotropia and exotropia. The success rate was not affected by previous strabismus surgeries nor by the initial angle of deviation., Conclusion: One-muscle and two-muscle horizontal strabismus surgery had similar long-term outcomes and did not differ by strabismus type nor by angle of deviation.

Introduction: Studies from developed and developing countries showed that the knowledge levels of stroke need improvement. Educational campaigns varied and were of limited influence predominantly because of their short duration and the need for financial support. The study aims to test the impact of a 3-min online video on the knowledge of stroke and factors influencing the knowledge score in four Arab countries., Methods: A cross-sectional web-based pre-post study was conducted in Egypt, Jordan, Lebanon, and the United Arab Emirates. The data were collected using the snowball technique. Participants were adults aged 18 years and above. The questionnaire sequence was conducting a pretest, followed by the educational video explaining stroke occurrence, types, risks, warning signs, preventive measures, and treatment, and finally, a posttest to evaluate the differences in knowledge from baseline. Statistical analysis included paired t -tests comparing pre-post-education stroke knowledge scores, while repeated measures ANOVA, adjusting for covariates, assessed mean changes., Results: The total number of participants was 2,721, mainly younger than 55 years. The majority had a university degree and were not healthcare professionals. A significant improvement was noted in the total knowledge score in all countries from a mean average ( M pretest  = 21.11; M posttest  = 23.70) with p  < 0.001. Identification of the stroke risks ( M pretest  = 7.40; M posttest  = 8.75) and warning signs ( M pretest  = 4.19; M posttest  = 4.94), understanding the preventive measures ( M pretest  = 5.27; M posttest  = 5.39) and the importance of acting fast ( M pretest  = 0.82; M posttest  = 0.85) improved from baseline with ( p  < 0.001) for all score components., Conclusion: The educational tool successfully enhanced public understanding of stroke risks, the identification of stroke signs, and the critical need for emergency action. The advantages of this video include its short length, free online access, use of evidence-based content in lay language, and reflective images. The ultimate goal remains the long-term improvement of sustainability by mandating full-scale trials., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Iskandar, Rahme, Salameh, Haddad, Sacre, Bahlol, Darwish, El Khatib, Safwan, Sakr, Rahhal, Hosseini and Cherfane.)

Objective: Ophthalmic complications frequently occur after procedures requiring general anaesthesia, but their incidence is widely variable and not well reported in the paediatric population. The aim was to identify the incidence and possible risk factors of postoperative ocular surface complications in a tertiary care centre., Methods and Analysis: This is a prospective study for paediatric patients undergoing general anaesthesia. An ophthalmologist performed the ocular examination after surgery. Parameters assessed were tear breakup time, punctate epithelial erosions and corneal abrasions. Multivariate logistic regression model was used to assess risk factors., Results: A total of 108 paediatric patients were recruited, 36.1% showed abnormal corneal finding: 32 (29.6%) had decreased tear breakup time, three (2.7%) had punctate epithelial erosions, three (2.7%) had both punctate epithelial erosions and decreased tear breakup time and one (0.9%) was found to have a unilateral corneal abrasion postoperatively. A higher rate of corneal complications was noted with younger age, prolonged surgery and surgery in the head and neck region., Conclusion: The rate of postoperative corneal abnormalities in children undergoing general anaesthesia was 36.1%, associated with younger age, prolonged surgery and surgery in the head and neck region., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: In patients with congenital long QT syndrome (LQTS), the risk of ventricular arrhythmia is correlated with the duration of the corrected QT interval and the changes in the ST-T wave pattern on the 12-lead surface electrocardiogram (12L-ECG). Remote monitoring of these variables could be useful., Aim: To evaluate the abilities of two wearable electrocardiogram devices (Apple Watch and KardiaMobile 6L) to provide reliable electrocardiograms in terms of corrected QT interval and ST-T wave patterns in patients with LQTS., Methods: In a prospective multicentre study (ClinicalTrials.gov identifier: NCT04728100), a 12L-ECG, a 6-lead KardiaMobile 6L electrocardiogram and two single-lead Apple Watch electrocardiograms were recorded in patients with LQTS. The corrected QT interval and ST-T wave patterns were evaluated manually., Results: Overall, 98 patients with LQTS were included; 12.2% were children and 92.8% had a pathogenic variant in an LQTS gene. The main genotypes were LQTS type 1 (40.8%), LQTS type 2 (36.7%) and LQTS type 3 (7.1%); rarer genotypes were also represented. When comparing the ST-T wave patterns obtained with the 12L-ECG, the level of agreement was moderate with the Apple Watch (k=0.593) and substantial with the KardiaMobile 6L (k=0.651). Regarding the corrected QT interval, the correlation with 12L-ECG was strong for the Apple Watch (r=0.703 in lead II) and moderate for the KardiaMobile 6L (r=0.593). There was a slight overestimation of corrected QT interval with the Apple Watch and a subtle underestimation with the KardiaMobile 6L., Conclusions: In patients with LQTS, the corrected QT interval and ST-T wave patterns obtained with the Apple Watch and the KardiaMobile 6L correlated with the 12L-ECG. Although wearable electrocardiogram devices cannot replace the 12L-ECG for the follow-up of these patients, they could be interesting additional monitoring tools., (Copyright © 2024.

Purpose: Guidelines recommend low-molecular-weight heparins (LMWHs) for patients with cancer-associated thrombosis. However, until recently, only dalteparin and tinzaparin were approved in the European Economic Area (EEA) for these patients. This study compares the benefit-risk profile of enoxaparin with dalteparin and tinzaparin for the extended treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and prevention of recurrence in adult patients with active cancer., Methods: A semi-quantitative structured benefit-risk assessment was conducted for the label-extension application of enoxaparin based on the benefit-risk action team descriptive framework: define decision context; determine key benefit and risk outcomes; identify data sources; extract data; interpret results., Results: The key benefits were defined as reduced all-cause mortality and venous thromboembolism (VTE) recurrence (including symptomatic DVT, fatal PE or non-fatal PE); the key risks were major and non-major bleeding of clinical significance, and heparin-induced thrombocytopenia (HIT). Enoxaparin demonstrated comparable effects for the reduction of VTE recurrence and all-cause mortality versus other EEA-approved LMWHs (dalteparin, tinzaparin). There was no evidence of a significant difference between enoxaparin and the comparator groups with regard to incidence of major and non-major bleeding. The data on HIT were too limited to assess the difference between the two groups., Conclusions: The assessment demonstrated a favourable benefit-risk profile for enoxaparin similar to that of other EEA-approved LMWHs for the treatment of DVT and PE and the prevention of recurrence in patients with active cancer and thus supported the label-extension approval., (© 2024 The Authors.

Background: Myelomeningocele (MMC) is a neural tube defect disease. Antenatal repair of fetal MMC is an alternative to postnatal repair. Many agents can be used as tocolytics during the in utero fetal repair such as β2-agonists and oxytocin receptor antagonists, with possible maternal and fetal repercussions. This study aims to compare maternal arterial blood gas analysis between terbutaline or atosiban, as tocolytic agents, during intrauterine MMC repair., Methods: Retrospective cohort study. Patients were divided into two groups depending on the main tocolytic agent used during intrauterine MMC repair: atosiban (16) or terbutaline (9). Maternal arterial blood gas samples were analyzed on three moments: post induction (baseline, before the start of tocolysis), before extubation, and two hours after the end of the surgery., Results: Twenty-five patients were included and assessed. Before extubation, the terbutaline group showed lower arterial pH (7.347 ± 0.05 vs. 7.396 ± 0.02 for atosiban, p = 0.006) and higher arterial lactate (28.33 ± 12.76 mg.dL -1 vs. 13.06 ± 6.35 mg.dL -1 , for atosiban, p = 0.001) levels., Conclusions: Patients who received terbutaline had more acidosis and higher levels of lactate, compared to those who received atosiban, during intrauterine fetal MMC repair., Competing Interests: Conflicts of competing interest The authors declare no conflicts of interest., (Copyright © 2024 Sociedade Brasileira de Anestesiologia.

Optical coherence tomography-angiography is a technique that allows us to non-invasively study in vivo the different retinal vascular networks. This allows a deeper understanding of retinal capillary anatomy and function, in addition to the pathophysiologic changes encountered in diverse diseases. The four retinal capillary layers have different anatomies and functions, implying distinct adaptation and roles in the course of the diseases. Diabetic retinopathy is the leading cause of blindness in working-age adults. Several studies have evaluated how each retinal capillary layer is specifically affected according to the stage of the disease. Unfortunately, too few studies have considered the intermediate capillary plexus as a separate layer, as it has often been incorporated in another layer. In this review, we shed light on the potential role the intermediate capillary plexus plays in the physiopathology of diabetic retinal disease as well as its potential use in grading diabetic retinopathy and its clinical added value in estimating the disease prognosis.

Background: Vitamin B12 deficiency is responsible for a variety of complications, particularly neurological/neuropsychiatric complications, including depression, irritability, paresthesia and insomnia. Since vitamin B12 is found in animal-derived products, vegans/vegetarians are at a greater risk for developing vitamin B12 deficiency., Aims: This study aims to investigate the occurrence of vitamin B12 deficiency among a sample of adult Lebanese population, with a particular emphasis on assessing the severity of its neurological/neuropsychiatric signs and symptoms, especially among vegans/vegetarians., Methodology: A cross-sectional study was conducted among a sample of 483 Lebanese adults. Data was collected through a standardized questionnaire that included socio-demographic characteristics, the Patient Health Questionnaire-9 (PHQ-9), Generalized anxiety disorders-7 (GAD-7), and the Insomnia Severity Index (ISI) scales., Results: Among the participants, 11.4% were in the vegan/vegetarian group, and about 43.1% had vitamin B12 deficiency. After analyzing the PHQ-9, GAD-7 and ISI total scores, higher scores were reported in participants with vitamin B12 deficiency, compared to individuals with normal vitamin B12 serum levels (p < 0.001). Regarding the diet type, vegans/vegetarians were more susceptible to developing depression compared to omnivores (mean scores of 11.92 vs 8.02 on the PHQ-9 scale, respectively, with p < 0.001). Of the patients with vitamin B12 deficiency, 81.1% reported having paresthesia compared to 43.7% of individuals with no vitamin B12 deficiency (p < 0.001)., Conclusion: Vitamin B12 deficiency in Lebanon is notably high and is linked to an increased risk of developing depression, generalized anxiety disorder, insomnia, and paresthesia. Vegans/vegetarians exhibit a higher susceptibility to developing depression compared to omnivores, whereas the risk of developing insomnia, generalized anxiety disorder and paresthesia was statistically insignificant when comparing vegans/vegetarians to omnivores., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Al Jassem et al.

The approach employed for the site preparation of the dental implant is a variable factor that affects the implant's primary stability and its ability to integrate with the surrounding bone. The main objective of this in vitro study is to evaluate the influence of different techniques used to prepare the implant site on the primary stability of the implant in two different densities of artificial bone., Materials and Methods: A total of 150 implant sites were prepared in rigid polyurethane blocks to simulate two distinct bone densities of 15 pounds per cubic foot (PCF) and 30 PCF, with a 1-mm-thick simulated cortex. The implant sites were equally distributed among piezoelectric surgery (PES), traditional drills (TD), and black ruby magnetic mallet inserts (MM). Two methods have been employed to evaluate the implant's primary stability, Osstell and micro-tomography., Results: In the present study, we observed significant variations in the implant stability quotient (ISQ) values. More precisely, our findings indicate that the ISQ values were generally higher for 30 PCF compared to 15 PCF. In terms of the preparation technique, PES exhibited the greatest ISQ values, followed by MM, and finally TD. These findings corresponded for both bone densities of 30 PCF (PES 75.6 ± 1.73, MM 69.8 ± 1.91, and TD 65.8 ± 1.91) and 15 PCF (PES 72.3 ± 1.63, MM 62.4 ± 1.77, and TD 60.6 ± 1.81). By utilizing Micro-CT scans, we were able to determine the ratio of the implant occupation to the preparation site. Furthermore, we could calculate the maximum distance between the implant and the wall of the preparation site. The findings demonstrated that PES had a higher ratio of implant to preparation site occupation, followed by TD, and then the MM, at a bone density of 30 PCF (PES 96 ± 1.95, TD 94 ± 1.88, and MM 90.3 ± 2.11). Nevertheless, there were no statistically significant differences in the occupation ratio among these three approaches in the bone density of 15 PCF (PES 89.6 ± 1.22, TD 90 ± 1.31, and MM 88.4 ± 1.17). Regarding the maximum gap between the implant and the site preparation, the smallest gaps were seen when TD were used, followed by MM, and finally by PES, either in a bone density 15 PCF (PES 318 ± 21, TD 238 ± 17, and MM 301 ± 20 μm) or in a bone density 30 PCF (PES 299 ± 20, TD 221 ± 16, and MM 281 ± 19 μm). A statistical analysis using ANOVA revealed these differences to be significant, with p -values of < 0.05., Conclusion: The outcomes of this study indicate that employing the PES technique and osteo-densification with MM during implant insertion may enhance the primary stability and increase the possibility of early implant loading.

Background: The COVID-19 pandemic highlights vaccination's critical role in reducing morbidity and mortality, depending on public attitude. This study aims to identify the estimates of COVID-19 vaccine acceptance in pregnant and lactating women, as well as associated potential factors., Methods: A cross-sectional study was conducted between August and September 2021, through an online survey and with a paper survey distributed in gynecology and pediatric clinics. Pregnant and breastfeeding women aged 18 years and above were recruited. The attitude scale was created specifically for evaluating attitudes towards the COVID-19 vaccine., Results: In total, 207 women participated, with 132 breastfeeding, 74 pregnant and 1 experiencing both conditions. Of these, one hundred and twenty women (58%) considered themselves at risk for COVID-19 infection. In addition, 51.7% (n = 107) of women expressed the intent to receive the vaccine once available. A multivariable linear regression was conducted taking the COVID-19 vaccination attitude scale as a dependent variable. The results revealed an R-squared value of 0.558, indicating that approximately 55.8% of the variance in the attitude scale was accounted for by the included predictors. The results showed that preventive measures (ß=2.25, 95% Confidence Interval (CI) [1.02; 3.48], p < 0.001), preference for vaccines made in Europe and America (ß=1.23; 95% CI [0.69-1.77], p < 0.001), protect yourself for getting sick (ß=4.22, 95% Confidence Interval (CI) [2.83; 5.61], p < 0.001) and belief in the importance of vaccination for themselves and their baby (ß=3.49; 95% CI [2.01; 4.98], p < 0.001) were associated with a positive attitude towards vaccination. Conversely, experiencing a previous bad reaction to a vaccine (ß= -1.35; 95% CI [0.85-1.85], p < 0.001) and concerns regarding COVID-19 vaccine safety (ß= -4.09; 95% CI [-5.98; -2.21], p < 0.001) were associated with a negative attitude towards vaccination., Conclusion: Our findings reveal that COVID-19 vaccine acceptability among pregnant and breastfeeding women, amidst the pandemic was insufficient to meet community immunity. The identified reasons for vaccine reluctance, notably concerns about safety for both personal health and the health of their pregnancy or newborns, along with insufficient information about the vaccine, underscore the pressing need to address these factors to improve immunization rates., (© 2024.

We present a case of severe esotropia and hypertropia in a monocular high myope with an inferolateral staphyloma. Surgery was undertaken to secure the inferior rectus to the lateral rectus via a modified partial Jensen technique, along with medial rectus recession successfully improving head and eye positions and ductions., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Due to the several interconnected crises that Lebanon has been facing for the past 4 years, many important social and environmental issues have been overlooked until more "pressing" ones are dealt with. Consequently, water pollution in Lebanon continues to worsen., Aim: This study aimed to describe the microbiological and chemical properties of the 10 main rivers in Lebanon and to assess their suitability for irrigation, while exploring some of the solutions to the problem., Methods: This cross-sectional study evaluated the pollution level of water from 10 rivers in Lebanon in June 2023 and their suitability for irrigation. Samples were collected at 3°C and their quality parameters were measured. Statistical analysis was conducted using R statistical software version 4.0.2., Results: Compared to the Food and Agriculture Organization (FAO) guidelines for safe irrigation water use, 4 out of the 10 samples had pH levels exceeding the permissible threshold, resulting in severe limitations on their usability. Three rivers had nitrate concentrations that exceeded the approved range, thus constraining their severe usage. Among the rivers, 60% had Escherichia coli levels higher than the permissible spectrum and 40% had faecal coliform counts exceeding FAO's upper limit recommendation. All water sources, however, had total dissolved solid levels that were within the recommended range., Conclusions: Polluted water can have a negative impact on human, wildlife and ecosystem health. Most of the assessed rivers in our study contained bacterial colonies, above the maximum recommended internationally. There is therefore an urgent need to address pollution issues in Lebanese waters to make them suitable for irrigation and other uses., (Copyright: © Authors 2024; Licensee: World Health Organization.

Background: The efficacy and safety of opioid-free anaesthesia during bariatric surgery remain debated, particularly when administering multimodal analgesia. As multimodal analgesia has become the standard of care in many centres, we aimed to determine if such a strategy coupled with either dexmedetomidine (opioid-free anaesthesia) or remifentanil with a morphine transition (opioid-based anaesthesia), would reduce postoperative morphine requirements and opioid-related adverse events., Methods: In this prospective double-blind study, 172 class III obese patients having laparoscopic gastric bypass surgery were randomly allocated to receive either sevoflurane-dexmedetomidine anaesthesia with a continuous infusion of lidocaine and ketamine (opioid-free group) or sevoflurane-remifentanil anaesthesia with a morphine transition (opioid-based group). Both groups received at anaesthesia induction a bolus of magnesium, lidocaine, ketamine, paracetamol, diclofenac, and dexamethasone. The primary outcome was 24-h postoperative morphine consumption. Secondary outcomes included postoperative quality of recovery (QoR40), incidence of hypoxaemia, bradycardia, and postoperative nausea and vomiting (PONV)., Results: Eighty-six patients were recruited in each group (predominantly women, 70% had obstructive sleep apnoea). There was no significant difference in postoperative morphine consumption (median [inter-quartile range]: 16 [13-26] vs 15 [10-24] mg, P =0.183). The QoR40 up to postoperative day 30 did not differ between groups, but PONV was less frequent in the opioid-free group (37% vs 59%, P =0.005). Hypoxaemia and bradycardia were not different between groups., Conclusions: During bariatric surgery, a multimodal opioid-free anaesthesia technique did not decrease postoperative morphine consumption when compared with a multimodal opioid-based strategy. Quality of recovery did not differ between groups although the incidence of PONV was less in the opioid-free group., Clinical Trial Registration: NCT05004519., (© 2024 The Author(s).)

To end the HIV epidemic as a public health threat, there is urgent need to increase the frequency, depth and intentionality of bidirectional and mutually beneficial collaboration and coordination between the USA and global HIV/AIDS response. The US Health Resources and Services Administration (HRSA) is uniquely positioned to showcase bidirectional learning between high-income and low-income and middle-income countries (LMICs) in the fight against HIV. For 30 years, HRSA has successfully administered the Ryan White HIV/AIDS Program (RWHAP), the largest federal programme designed specifically for people with HIV in the USA. Further, HRSA has developed and delivered innovative, cost-effective, impactful HIV programmes in over 30 countries as an implementing agency for the US President's Emergency Plan for AIDS Relief (PEPFAR). When PEPFAR was authorised in 2003, HRSA rapidly developed systems and infrastructures to deliver life-saving treatment, initiated workforce development programmes to mitigate health worker shortages, and laid the path for transitioning PEPFAR activities from US-based organisations to sustainable, country-led entities. As global programmes matured, lessons learnt within LMICs gradually began strengthening health services in the USA. To fully optimise synergies between RWHAP and PEPFAR, there is a critical need to build on successful initiatives, harness innovation and technology, and inculcate the spirt of multidirectional learning into global health. HRSA is promoting bidirectional learning between domestic and international HIV programming through documenting, sharing and implementing strategies, lessons learnt, best practices and effective models of care to accelerate achievement of HIV epidemic control and support country-led, sustained responses to public health threats., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: In the context of the COVID-19 pandemic, pharmacists, despite their vital contributions, have faced significant challenges that have impacted their mental well-being, potentially leading to the development of Post-Traumatic Stress symptoms (PTSS). The aim of this study was to investigate the role of work-related fatigue as a potential moderator in the relationship between pharmacists' resilience and their likelihood of experiencing PTSS during the COVID-19 pandemic., Methods: A cross-sectional survey was conducted online in eight countries from January to December 2021, including Brazil, Lebanon, Nigeria, Pakistan, Poland, Serbia, and Tunisia. The mediation analysis was conducted using PROCESS MACRO (an SPSS add-on) v3.4 model 1, taking work fatigue as a moderator in the association between resilience and PTSS., Results: A total of 442 pharmacists were enrolled in this study (mean age = 33.91 ± 10.36 years) with 59.5% of them being females. The results were adjusted over country, gender, working in contact with COVID-19, working patients, working mandatory hours, working voluntary hours, age, household crowding index and number of months engaged in COVID-19. The interactions resilience by physical (Beta = 0.02; p = .029), mental (Beta = 0.02; p = .040) and emotional (Beta = 0.03; p = .008) work fatigue were significantly associated with PTSS; for pharmacists with low to moderate levels of physical (Beta = - 0.33; p < .001 and Beta = - 0.21; p = .001), mental (Beta = - 0.29; p < .001 and Beta = - 0.18; p = .006) and emotional (Beta = - 0.31; p < .001 and Beta = - 0.17; p = .008) work fatigue, higher resilience was significantly related to lower PTSS levels. However, for pharmacists with high levels of physical/mental/emotional work fatigue, the association between resilience and PTSS became non-significant., Conclusion: This study highlights the complex relationship between work-related fatigue, resilience, and PTSS in pharmacists. It emphasizes the need to address work-related fatigue for pharmacists' psychological well-being during crises, offering insights for tailored support and interventions., (© 2024. The Author(s).)

Selective pressures on viruses provide opportunities to establish target site specificity and mechanisms of antivirals. Enterovirus (EV)-A71 with resistant mutations in the stem loop (SL) II internal ribosome entry site (IRES) (SLII resist ) were selected at low doses of the antiviral dimethylamiloride (DMA)-135. The EV-A71 mutants were resistant to DMA-135 at concentrations that inhibit replication of wild-type virus. EV-A71 IRES structures harboring resistant mutations induced efficient expression of Luciferase messenger RNA in the presence of noncytotoxic doses of DMA-135. Nuclear magnetic resonance indicates that the mutations change the structure of SLII at the binding site of DMA-135 and at the surface recognized by the host protein AU-rich element/poly(U)-binding/degradation factor 1 (AUF1). Biophysical studies of complexes formed between AUF1, DMA-135, and either SLII or SLII resist show that DMA-135 stabilizes a ternary complex with AUF1-SLII but not AUF1-SLII resist . This work demonstrates how viral evolution elucidates the (DMA-135)-RNA binding site specificity in cells and provides insights into the viral pathways inhibited by the antiviral.

Objective: This study aimed to examine the outcomes of COVID-19 and a collapsing economy on the mental well-being (MWB) of the general Lebanese population. Methods: A cross-sectional study was conducted online in May 2020 and enrolled 502 adults. Results: Mental well-being had a mean of 14.80 (14.37; 15.24). A lower MWB was associated with female gender (beta=-1.533 [-2.324; -0.743]), university education (beta=-2.119 [-3.353;-0.885]), fear of COVID-19 (beta=-0.131 [-0.199; -0.063]), fear of poverty (beta=-0.232 [-0.402;-0.063]), verbal violence at home (beta=-3.464 [-5.137; -1.790]), and chronic disease (beta=-1.307 [-2.283; -0.330]). Better family satisfaction (beta=0.380 [0.235; 0.525]) and better financial situation (beta=0.029 [0.003; 0.055]) were significantly correlated with better MWB. In the subsample of workers/looking for a job, additional factors affected MWB: physical exercise (beta =1.318 [0.370; 2.265]) was associated with better QOL, while being a previous waterpipe smoker, being self-employed before the crisis (beta=-1.22 [-2.208;-0.231]), working from home since the economic crisis (-1.853 [-3.692; -0.013]), and worrying about the long-term effects of the crisis on one's employment status (beta=-0.433 [-0.650; -0.216]) were associated lower MWB. It is noteworthy that closure of the institution yielded a borderline result (B = -1.2; p = .094), while the fear of COVID-19 was not significantly associated with MWB (B = -0.054; p =0.192). Conclusion: This study showed that, during the pandemic, economic and other factors, directly or indirectly related to COVID-19, significantly affected quality of life. The fear of COVID-19 and fear of poverty mainly impacted the MWB of the general population. However, the fear of COVID-19 lost its significance among workers, who reported that factors negatively affecting their MWB are directly related to their employment and the already collapsing economy in Lebanon., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: The purpose is to to explore the effects of the Lebanese economic crisis on the ophthalmology workload in Lebanon, and the concomitant influence of the COVID-19-related lockdown and Beirut port explosion., Methods: Data pertaining to all the clinic visits to the Ophthalmology Department at the American University of Beirut Medical Center between January 01, 2019, and December 31, 2021, were extracted. Completed visits to different subspecialties were used to analyze the different parameters. All parameters were compared across the 3 years., Results: We included 102,810 completed visits in this study. A total decrease of 15.3% occurred in visits between 2019 and 2020. The mean number of patients per month decreased significantly between 2019 and 2020 in retina/uveitis and glaucoma/anterior segment clinics. The same trend was observed in pediatric/neuro-ophthalmology and cornea/refractive surgery, although it did not reach statistical significance. For oculoplastics, the workload actually tended to increase from 2019 to 2021. During the pandemic-related lockdown (March, April, and May 2020), the workload decreased by 37.8% in oculoplastics, 63.4% in pediatric/neuro-ophthalmology, 52.8% in retina/uveitis, 60.2% in cornea/refractive surgery, and 50.7% in glaucoma/anterior segment. After the Beirut port explosion in August 2020, an overall decrease of 30.2% was found in the number of patient visits in all sub-specialties, while the number of patients in oculoplastics remained nearly unchanged., Conclusion: The ophthalmology workload was strongly affected by the economic crisis in all subspecialties especially with the pandemic in 2020, except for oculoplastics. During the pandemic, the most affected subspecialty was the pediatric/neuroophthalmology, while oculoplastics was the least affected., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Middle East African Journal of Ophthalmology.)

This study aimed to identify the perceived advantages and drawbacks of teleworking and their correlates, including health problems, among Lebanese workers holding a university degree. A web-based cross-sectional self-report questionnaire created on Google Forms was used to survey 230 participants through snowball sampling between October 2022 and March 2023. The majority of respondents recognized both the advantages (67.03%) and drawbacks (66.34%) associated with teleworking, suggesting mixed feelings toward this format. Despite the limited satisfaction with teleworking, respondents acknowledged the advantages associated with remote working; in particular, younger, less physically active, and more educated participants valued teleworking more than their counterparts. The mean perception of advantages and drawbacks of telework did not significantly change with participants' work status (hybrid, online, and in-person). The study revealed a high prevalence of consistent sleeping difficulty (35.7%), limited regular physical activity (60.4%), work-related musculoskeletal disorders (48.7%), back pain (5.7%), and visual disorders (48%) among Lebanese workers. Despite the limited satisfaction with teleworking, respondents acknowledged advantages such as cost and time savings. Older workers showed a preference against teleworking, potentially due to its impact on well-being. Factors such as education, career satisfaction, and prior teleworking experience influenced individuals' perceptions of telework benefits.

Objective: People with autoimmune and inflammatory rheumatic disease (AIIRD) are at an increased risk of morbidity from COVID-19. While COVID-19 vaccination is effective at reducing disease complications, there have been significant levels of vaccine hesitancy in people with AIIRD. We aimed to understand vaccine hesitancy and promote shared decision-making by describing the experiences and perspectives of people with AIIRD who had concerns with COVID-19 vaccinations., Methods: Adults with AIIRD on immunosuppressive medications who expressed concerns regarding the COVID-19 vaccination were purposively sampled until thematic saturation. Individual semi-structured interviews were conducted and analysed using reflexive thematic analysis., Results: Sixteen adults with an AIIRD were interviewed. Thematic analysis yielded four themes: heightened sense of vulnerability; determining individual suitability; desperate for freedom and relief; deterred by scepticism., Conclusions: The perspectives of people with AIIRD towards the COVID-19 vaccination were shaped by a sense of vulnerability. The decision-making experience was challenging, resulting from struggles with handling information, dealing with external pressures, and facing negativity., Practice Implications: A collaborative approach, involving close family and friends and avoiding negativity and pressure can improve engagement and support decision-making around COVID-19 vaccination. Clearly addressing potential risks of vaccination may prevent subsequent regret and hesitancy if they arise., Competing Interests: Declaration of Competing Interest There are no conflicts of interest to report from the authors., (Copyright © 2023 The Authors.
