Evaluation of the Performance and Safety of a New Micro-Needle Technology in Comparison With the Classic Needle on the Antiaging Effects of a Biorevitalizing Solution: A Randomized Split Face/Neck Study.

BACKGROUND: Skin biorevitalization involves multiple intradermal injections to enhance skin quality, but precise dermal targeting can be challenging due to variations in skin thickness smaller, less painful needles with fewer skin reactions are attractive options. AIMS: This study evaluates a new Micro-Needle device's performance and safety in comparison with the classic needle used in skin biorevitalization. PATIENTS/METHODS: Subjects with facial and neck skin aging were enrolled. Safety outcomes, including immediate and local tolerability, were assessed. Performance outcomes measured skin radiance, wrinkles and photoaging grade, hydration, subepidermal low echogenic band, dermis thickness, and skin elasticity. Both subjects and investigators recorded Global Aesthetic Improvement Scale scores. RESULTS: Micro-Needle injections demonstrated superior performance compared to the classic needle, influenced by the specific skin zones and thickness. Micro-Needle was superior for skin wrinkles at D49 for periorbital zone and nasolabial folds by -14.5% (p = 0.01) and -15% (p = 0.004), respectively, and for neck by 9.6% (p = 0.0008). The Nanosoft device showed a faster improvement for skin hydration at D42 for the cheek zone (p = 0.04) and at D75 for the neck area (p = 0.01); and for skin radiance at D75 (p = 0.03) and at D120 (p = 0.0098). Ex vivo studies confirmed the Micro-Needle's accuracy in product placement in the dermis. Adverse events were milder with Micro-Needle and no serious adverse events occurred. CONCLUSIONS: Both needles significantly improved skin quality, but Micro-Needle enhanced the outcomes of skin biorevitalization procedures, particularly in terms of skin wrinkle reduction, elasticity, and overall skin hydration.

Epidemiology of Breast, Corpus Uteri, and Ovarian Cancers in Lebanon With Emphasis on Breast Cancer Incidence Trends and Risk Factors Compared to Regional and Global Rates.

OBJECTIVES: This study explores the incidence and trends of breast (Bca), corpus uteri (CUca), and ovarian (Oca) cancer in Lebanon, a Middle Eastern country. It compares the Bca rates to regional and global ones and discusses Bca risk factors in Lebanon. INTRODUCTION: Globally, Bca is the premier cause of cancer morbidity and mortality in women. METHODS: Data on female Bca, CUca, and Oca published by the Lebanese national cancer registry were obtained (ie, for the years of 2005 to 2016). The age-standardized incidence rates (ASIRw) and age-specific rates per 100,000 female population were computed. RESULTS: From 2005 to 2016, Bca, Oca, and CUca ranked first, sixth, and seventh, respectively, for cancer incidence among women in Lebanon. Bca alone accounted for 39.4% of all new female cancer cases. The ASIRw increased significantly for Bca and CUca (APC: 3.60 and 3.73, P < .05) but not for Oca (APC: 1.27, P > .05). The Bca ASIRw (per 100,000) increased significantly from 71.0 in 2005 to 115.6 in 2013 (P < .05), then decreased steadily but non-significantly to reach 96.8 in 2016 (P > .05). Lebanon's Bca ASIRw is comparable to developed countries. This may reflect altered sociological and reproductive patterns as the country transitions from regional to global trends. The five-year age-specific rates analysis revealed that Bca rates rose steeply from 35-39 to 50-54, dropped slightly between 55 and 64, then rose till 75+. The five-year age-specific rates between 35 and 54 among Lebanese women were amongst the highest worldwide from 2008 to 2012, even higher than the rates in Belgium, which had the highest ASIRw of Bca worldwide in 2020. CONCLUSION: Lebanon's Bca ASIRw is among the highest globally. It's important to investigate the contributing factors and develop a national Bca control strategy. This study supports the national recommendation in initiating Bca screening at age 40 for women.

A hyaluronic acid-based micro-filler improves superficial wrinkles and skin quality: a randomized prospective controlled multicenter study.

BACKGROUND: NCTF®135HA is a bio-revitalizing solution containing hyaluronic acid designed to compensate for skin dehydration, fatigue, and fine wrinkles associated with endogenous and environmental aging. METHODS: We conducted a randomized, active-controlled study to evaluate the efficacy and tolerability of NCTF®135HA injections on the face (crow's feet), neck, and décolleté regions. Subjects were randomly assigned (3:1) to receive three NCTF®135HA treatment sessions plus twice-daily anti-aging moisturizer cream or cream alone (control). The primary outcome was the reduction in superficial wrinkles between baseline and Day (D)75 in the three areas, assessed by profilometric measures, clinical scoring, subjective changes, and tolerability. RESULTS: 146 subjects were randomized to NCTF®135HA (n = 107) or control (n = 38). At D75 and D120, NCTF®135HA significantly reduced wrinkles in all three areas and improved facial radiance scores compared with the control. Skin hydration significantly increased 7 d after the last NCTF®135HA injection. Self-esteem scales showed statistically significant improvements at D75 and D120 in subjects treated with NCTF®135HA versus baseline. Most adverse events were mild, resolved within 48 h, and were related to the injection procedure. CONCLUSION: NCTF®135HA is an effective and well-tolerated treatment to reduce the skin signs of aging. The results are significantly superior to a routine anti-aging cream alone.(Funded by Laboratories FILLMED; ID-RCB number: 2018-A03167-48; clinicaltrials.gov number: NCT05609617).

University students' intentions to seek psychological counseling, attitudes toward seeking psychological help, and stigma.

BACKGROUND: Mental health problems are prevalent among university students worldwide. Studies have shown that most students do not disclose and do not get the psychological help and support they need. OBJECTIVES: This survey aims to investigate the intentions to seek psychological counseling (ISC) among university students, their attitudes toward seeking professional psychological help (ATSPPH), and the predictors of those intentions and attitudes including stigma. DESIGN AND METHODS: a cross-sectional survey was conducted among 420 students at the American University of Beirut (AUB). RESULTS: Depression, test anxiety, and difficulty sleeping are the three main reasons students would seek psychological help. The source the students most preferred to ask for help was one's family followed by psychologists and psychiatrists. Students' ATSPPH is a positive predictor of their ISC, while students' self-stigma of seeking help (SSOSH) is a negative predictor of their ATSPPH. Moreover, students' awareness of the psychological help system available on campus, free of charge, is a positive predictor for both ISC and ATSPPH. CONCLUSION: Different interventions are needed to reduce stigma and enhance students' mental health literacy and awareness of the available professional psychological help on campus.

Lung Cancer and Risk Factors in Lebanon: Epidemiology, Temporal Trends, and Comparison to Countries From Different Regions in the World.

BACKGROUND: Lung cancer (Lca) is the leading cause of cancer morbidity and mortality worldwide. This study examines the Lca incidence and trends in Lebanon and compares them to regional and global ones. It also discusses Lca risk factors in Lebanon. METHODS: Lung cancer data from the Lebanese National Cancer Registry for 2005 to 2016 was obtained. The age-standardized incidence rates (ASRw) and age-specific rates per 100 000 population were calculated. RESULTS: Lung cancer ranked second for cancer incidence in Lebanon from 2005-2016. Lung cancer ASRw ranged from 25.3 to 37.1 per 100 000 males and 9.8 to 16.7 per 100 000 females. Males 70-74 and females 75+ had the highest incidence. Lung cancer ASRw in males increased significantly at 3.94% per year from 2005 to 2014 (P > .05), then decreased non-significantly from 2014 to 2016 (P < .05). Lung cancer ASRw in females increased significantly at 11.98% per year from 2005 to 2009 (P > .05), then increased non-significantly from 2009 to 2016 (P < .05). Males' Lca ASRw in Lebanon was lower than the global average in 2008 and became similar in 2012 (34.1 vs 34.2 per 100 000); However, females' Lca ASRw was almost comparable to the global average in 2008 and exceeded it in 2012 (16.5 vs 13.6, respectively, per 100 000). Males' and Females' Lca ASRw in Lebanon were among the highest in the Middle East and North Africa (MENA) region but lower than those estimated for North America, China and Japan, and several European countries. The proportion of Lca cases attributed to smoking among Lebanese males and females was estimated at 75.7% and 66.3% for all age groups, respectively. The proportion of Lca cases attributed to air pollution with PM10 and PM2.5 in Lebanon was estimated at 13.5% for all age groups. CONCLUSION: Lung cancer incidence in Lebanon is among the highest in the MENA region. The leading known modifiable risk factors are tobacco smoking and air pollution.

The Effects of a Non-crossed-linked Hyaluronic Acid Gel on the Aging Signs of the Face versus Normal Saline: A Randomized, Double-blind, Placebo-controlled, Split-faced Study.

Background: Skin bio-revitalization improves skin quality globally; it permits the rejuvenation of the skin by increasing hydration and by reconstructing an optimal physiological environment for the skin cells together with a micro-filling effect. Objective: To assess the comparative efficacy of a non-cross-linked hyaluronic acid (NCHA) preparation (M-HA®10, FILLMED Laboratories, France) on fine lines reduction and on skin hydration, radiance and mechanical properties, after three sessions of multiple intradermal injections, active versus placebo, on the face of subjects presenting aging signs. Methods: Thirty healthy subjects received filler injections on one side and a control solution (saline) on the contralateral side of the face. Fine lines depth, skin hydration, and mechanical properties were evaluated using instrumental methods. Skin radiance, cheek fold and crow's feet were scored clinically. In addition, Investigator and subject satisfaction rates were evaluated by the Global Aesthetic Improvement Scale and a subject self-assessment questionnaire. Results: Ten days after the last multi-injection session, the following significant results were observed compared to the control: a reduction of both crow's feet wrinkle depth (in the 110 to 1000µm range, -10% for NCHA and +7% for control) and clinical scoring of cheek wrinkles, and increases in skin radiance and hydration (+35%) and also skin firmness (+27%). The Investigator found that NCHA either improved or much improved the aesthetic aspect on 82% of subjects whereas no improvement was found on the saline side. Subjects found that NCHA significantly reduced wrinkles and increased both skin firmness and elasticity. Conclusion: Intradermal injection of NCHA can improve the quality of facial skin with aging signs by reducing fine wrinkles and improving hydration, firmness and radiance.

Protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the omicron variant and severe disease: a systematic review and meta-regression.

BACKGROUND: The global surge in the omicron (B.1.1.529) variant has resulted in many individuals with hybrid immunity (immunity developed through a combination of SARS-CoV-2 infection and vaccination). We aimed to systematically review the magnitude and duration of the protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against infection and severe disease caused by the omicron variant. METHODS: For this systematic review and meta-regression, we searched for cohort, cross-sectional, and case-control studies in MEDLINE, Embase, Web of Science, ClinicalTrials.gov, the Cochrane Central Register of Controlled Trials, the WHO COVID-19 database, and Europe PubMed Central from Jan 1, 2020, to June 1, 2022, using keywords related to SARS-CoV-2, reinfection, protective effectiveness, previous infection, presence of antibodies, and hybrid immunity. The main outcomes were the protective effectiveness against reinfection and against hospital admission or severe disease of hybrid immunity, hybrid immunity relative to previous infection alone, hybrid immunity relative to previous vaccination alone, and hybrid immunity relative to hybrid immunity with fewer vaccine doses. Risk of bias was assessed with the Risk of Bias In Non-Randomized Studies of Interventions Tool. We used log-odds random-effects meta-regression to estimate the magnitude of protection at 1-month intervals. This study was registered with PROSPERO (CRD42022318605). FINDINGS: 11 studies reporting the protective effectiveness of previous SARS-CoV-2 infection and 15 studies reporting the protective effectiveness of hybrid immunity were included. For previous infection, there were 97 estimates (27 with a moderate risk of bias and 70 with a serious risk of bias). The effectiveness of previous infection against hospital admission or severe disease was 74·6% (95% CI 63·1-83·5) at 12 months. The effectiveness of previous infection against reinfection waned to 24·7% (95% CI 16·4-35·5) at 12 months. For hybrid immunity, there were 153 estimates (78 with a moderate risk of bias and 75 with a serious risk of bias). The effectiveness of hybrid immunity against hospital admission or severe disease was 97·4% (95% CI 91·4-99·2) at 12 months with primary series vaccination and 95·3% (81·9-98·9) at 6 months with the first booster vaccination after the most recent infection or vaccination. Against reinfection, the effectiveness of hybrid immunity following primary series vaccination waned to 41·8% (95% CI 31·5-52·8) at 12 months, while the effectiveness of hybrid immunity following first booster vaccination waned to 46·5% (36·0-57·3) at 6 months. INTERPRETATION: All estimates of protection waned within months against reinfection but remained high and sustained for hospital admission or severe disease. Individuals with hybrid immunity had the highest magnitude and durability of protection, and as a result might be able to extend the period before booster vaccinations are needed compared to individuals who have never been infected.

Prescribing antibiotics in adults with respiratory tract infections in Lebanon.

INTRODUCTION: Antibiotic resistance is a global concern that has significant health and economic burden. The inappropriate use of antibiotics is a major cause of antibiotic resistance; this includes both unnecessary and incorrect prescriptions. Most antibiotics are prescribed in primary care, mainly for respiratory tract infections. This study examines the prescribing practices of physicians for respiratory tract infections in ambulatory settings in Lebanon. METHODS: The study was a cross-sectional review of prescriptions given to a group of employees working in two companies in Greater Beirut in Lebanon (n = 469) between September 2017 and March 2018. Prescriptions and related medical reports were reviewed. Data on the type of infection and the employees' demographics were collected. Antibiotic treatment was considered appropriate based on its adherence to international scientific societies' recommendations and clinical guidelines, including those of the Infectious Diseases Society of America. RESULTS: A total of 372 medical reports and prescriptions were reviewed; 88.2% of these prescriptions included antibiotics. The rate of antibiotic treatment was 82.0% for a diagnosis of flu-like symptoms and 94.6% for acute pharyngitis, of which 34.5% included third generation cephalosporins and fluoroquinolones. Around 93.7% of patients with acute bronchitis without pneumonia received antibiotics, mostly broad-spectrum ones. A significant association was found between the specialty of the prescribing physicians and some types of upper respiratory tract infections. CONCLUSION: This study reveals a high prevalence of inappropriate antibiotic prescribing for respiratory tract infections in the Lebanese ambulatory practice, contributing to the emergence of antimicrobial resistance in the country. It calls for urgent multifaceted interventions to limit unnecessary use and promote antibiotic stewardship.

A Pilot Intervention to Promote Positive Parenting in Refugees from Syria in Lebanon and Jordan.

BACKGROUND: Early childhood development (ECD) is a crucial milestone that shapes a child's health, wellbeing, education, and personality. Several factors come into play, and each requires the nurturing care of caregivers. Although the importance of ECD is well understood, the implementation of ECD programs is scarce, especially in poor and vulnerable communities. OBJECTIVE: To improve parents' wellbeing, parenting stress levels, parenting behavior, and discipline strategies after the implementation of a newly designed parenting intervention. PARTICIPANTS AND SETTING: Parents from Syria (125 mothers and fathers) in three refugee camps in Lebanon and Jordan. METHODS: This was a pilot cohort study in which parents' wellbeing, parenting stress levels, parenting behavior, and discipline strategies were evaluated before and after participating in training in the form of interactive and educational sessions to ameliorate their relations and interactions with their children. RESULTS: By the end of this study, parents' mental health and wellbeing improved (p < 0.001, Cohen's d: 0.61) and their parenting index score was reduced (p < 0.001, Cohen's d: 1.24). Some of their dysfunctional interactions with their children as well as the perceived difficulties and conduct problems in their children aged 3 to 6 years were also reduced significantly. CONCLUSION: The intervention used in this study succeeded in improving some aspects of parenting practices and disciplines and in improving the parents' wellbeing; however, more research is needed to assess its long-term effects on parents and their children. Moreover, some adjustments need to be made in the intervention to be more adapted to the context of refugees and underprivileged communities.
