RESUMO

BACKGROUND: The Arab world is one of the global regions the most directly concerned by, and suffering from climate change's adverse consequences. As such, there appears to be a strong need for an understanding of how Arab people may emotionally respond to climate change. Providing valid and reliable measures of climate change anxiety (CCA) can help gain a clear overview of the situation in Arab countries, and allow to intervene timely and effectively to mitigate any adverse effects on Arab people's mental health. To this end, the present study sought to validate the Arabic language version of the Climate Change Anxiety Scale (CCAS) in a sample of native Arabic-speaking adults from the general population of Lebanon. METHODS: This study adopted a cross-sectional approach and enrolled 763 adults between July and September 2023. RESULTS: A confirmatory analysis of the one-factor model showed poor fit indices as follows: CFI = 0.90, GFI = 0.83, SRMR = 0.048 and RMSEA 0.131 [90% CI 0.123, 0.138). The two-factor model showed a satisfactory fit with a high CFI of and a GFI of 0.91 and a SRMR of 0.04 and RMSEA of 0.05 [90% CI 0.04, 0.06]. Both McDonald's omega and Cronbach alpha values were high for the overall CCAS score (α = 0.96 and ω = 0.96) in the whole sample. Configural, metric and scalar invariance across gender was demonstrated. No significant difference was found between males and females in terms of total CCAS scores (24.53 ± 10.59 vs. 26.03 ± 11.17, t(761) = -1.82, p = .069). Higher CCA, functional impairment and cognitive impairment scores were significantly associated with higher depression, anxiety and stress. CONCLUSION: The reliability and validity of the CCAS in its Arabic version were proven. The availability of this self-report measure could offer a chance to assess CCA among Adults speaking Arabic, and to spread its future use for screening and research purposes.

RESUMO

BACKGROUND: Accurately measuring violent ideations would be of particular high relevance in Arab countries, which are witnessing an unprecedented increase in violence rates among adolescents because of the widespread social, economic and political unrest in the region. Therefore, the present study aimed to test the psychometric properties of an Arabic translation of the 12-item and the 7-item forms of the Violent Ideations Scale (VIS and VIS-SF) in a sample on non-clinical Arabic-speaking adolescents. METHODS: Five hundred seventy-seven community adolescents (mean age of 15.90 ± 1.73 years, 56.5% females) answered an anonymous online survey comprising an Arabic translation of the Violent Ideations Scale (VIS) and a measure of physical aggression. RESULTS: Confirmatory factor analyses (CFA) offered support for the single-factor structure of the Arabic VIS and the VIS-SF. Both the long and short forms of the scale yielded excellent internal consistency, with McDonald's ω coefficients of 0.96 and 0.94 and Cronbach's α coefficients of 0.96 and 0.94, respectively. Multi-group CFA established measurement invariance across gender groups. Finally, results revealed significant and positive correlations between the two forms of the VIS and physical aggression scores, thus supporting concurrent validity. CONCLUSION: Both the VIS and VIS-SF have demonstrated good psychometric properties in their Arabic versions, and suitability for sound assessment of violent ideations. We therefore expect that these measures assist clinicians in risk assessment and management of violence, and help foster research in this area in Arab countries.

RESUMO

BACKGROUND: Avoidant Restrictive Food Intake Disorder (ARFID) is a new diagnosis added to the DSM-5 characterized by pathological eating habits without body image disturbances. Previous findings demonstrated a general association between high levels of perfectionism and low levels of self-esteem in association with general eating disorders. However, research is scant when it comes to ARFID specifically. Subsequently, although self-esteem is seen to moderate the association between perfectionism and general eating disorders, this research study aims to explore the same moderation but with ARFID specifically. METHODS: For this study, 515 Lebanese adults from the general Lebanese population were recruited from all over Lebanon, 60.1% of which were females. The Arabic version of the Big Three Perfectionism Scale- Short Form (BTPS-SF) was used to measure self-critical, rigid and narcissistic perfectionism; the Avoidant/Restrictive Food Intake Disorder screen (NIAS) was used to score the ARFID variable; the Arabic-Single Item Self-Esteem (A-SISE) was the scale used to measure self-esteem. RESULTS: Across the different perfectionism types, self-esteem was seen to moderate the association between narcissistic perfectionism and ARFID (Beta = - 0.22; p =.006). At low (Beta = 0.77; p <.001), moderate (Beta = 0.56; p <.001) and high (Beta = 0.36; p =.001) levels of self-esteem, higher narcissistic perfectionism was significantly associated with higher ARFID scores. CONCLUSION: This study brought to light some crucial clinical implications that highlight the need for interventions that help in the enhancement of self-esteem in patients with high perfectionism and ARFID. This study suggests that clinicians and healthcare professionals should focus more on risk factors influencing the development and maintenance of ARFID-like symptoms.

RESUMO

BACKGROUND: The relationship between behavioral problems and asthma is bidirectional; while the presence of a chronic disease such as asthma might predispose the person to stress, anxiety, and other behavioral issues, behavioral problems might in turn cause uncontrolled asthma through nonadherence to asthma management strategies. In Lebanon, behavioral problems and uncontrolled asthma could be of significant concern for adolescents. Consequently, we found it necessary to evaluate association between behavioral problems and uncontrolled asthma in a sample of Lebanese adolescents. METHODS: Data for this cross-sectional study were collected using the snowball sampling technique in July 2023. The questionnaire was developed with Google Forms and distributed to participants via social media platforms and messaging applications. The Asthma Control Test (ACT) was used to check for uncontrolled asthma, and the Youth Self-Report (YSR) scale was used to assess behavioral problems. It yields nine subscales (anxious-depressed, withdrawn-depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, aggressive behavior, and other problems) and a total score. RESULTS: When taking each behavior score as an independent variable, older age was associated with lower ACT scores (more controlled asthma); F(15, 186) = 3.66, P = 0.014, and 95% Confidence Interval (CI) [-0.85, -0.10]. Living in a rural area, compared to urban was associated with higher ACT scores, P = 0.018, and 95% Confidence Interval (CI) [0.28, 2.94]. The intake of the COVID-19 vaccine, P = 0.003 and 95% CI [0.73, 3.55]; waterpipe smoking, P = 0.017 and 95% CI [0.38, 3.85]; and having more somatic complaints, P = 0.005 and 95% CI [0.04, 0.25], also were significantly associated with higher ACT scores (more uncontrolled asthma). When taking the total behavior score as an independent variable, higher YSR scores were associated with higher ACT scores (more uncontrolled asthma), F(10, 191) = 4.30, P = 0.038, and 95% CI [0.003, 0.10]. CONCLUSION: Our findings support the inclusion of mental health treatments for better asthma control and point to a link between behavioral issues and uncontrolled asthma. In a developing nation without a clear established strategy for asthma prevention, the findings of this study could help develop potentially beneficial public health treatments.

RESUMO

BACKGROUND: Little evidence is available about psychological stressors in Lebanese asthmatic adolescents, where health-risk behaviors are a serious threat to public health. In addition, the COVID-19 epidemic has had a substantial influence on adolescents' mental health globally, especially in Lebanon, where the ongoing economic and political challenges have largely impacted their psychological well-being. This study aimed to explore the association of asthma and the COVID-19 infection with behaviors among Lebanese adolescents. METHODS: Data were collected in July 2023, using the snowball sampling technique. Inclusion criteria for participation in the study included being of a resident and citizen of Lebanon and aged 12-18 years. Behavioral problems were assessed using the Youth Self-Report (YSR) scale, which yields nine subscales (anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, aggressive behavior, and other problems) and a total score. RESULTS: Asthma was significantly associated with somatic complaints (Beta [ß] = 2.98), attention problems (ß = 0.01), and other behavioral problems (ß = 0.68). Having contracted the COVID-19 infection, compared to healthy asymptomatic state (ß = 1.55), was significantly associated with more anxious behaviors. In the case of stratifying the analysis in terms of gender, the results showed that the presence of asthma was significantly associated with more social behaviors (ß = 3.31), thought problems (ß = 2.91), attention problems (ß = 0.02), other behavioral problems (ß = 1.71), and total behavioral problems (ß = 5.71) in males. In case stratifying the analysis as to school type, the presence of asthma was significantly associated with more somatic complaints (ß = 2.77) in participants from private schools whereas it was significantly associated with more total behavioral problems (total YSR scores) (ß = 5.05) in participants from public schools. CONCLUSION: It is confirmed that asthma and psychiatric disorders are interconnected, so it would be of great importance to include screening through a psychological intervention in treating asthmatic adolescents by means of (1) recognizing factors affecting patients' mental health, and (2) regulating uncontrolled behaviors that can exacerbate symptoms in order to avoid the future morbidity.

RESUMO

The interplay between insomnia and PTSD symptoms remains misunderstood, and seems to be influenced by other factors like individual resilience. Our study examined the moderating role of resilience in the relationship between insomnia and PTSD symptoms among a sample of Lebanese adolescents, in the aftermath of the 2023 earthquake. This cross sectional study, conducted in April, 2 months after the earthquake, enrolled 546 Lebanese adolescents. We used the Sleep Self Report, the Resilience Scale for Adolescents and the 13-item Children's Impact of Event Scale. The interaction insomnia severity by resilience was significantly associated with PTSD scores. At low, moderate and high resilience levels, higher insomnia severity was significantly associated with lower PTSD. Resilience moderated the relationship between insomnia and PTSD, mitigating the detrimental impact of disrupted sleep on PTSD symptoms. This data can guide healthcare administrators and psychiatric caregivers in classifying risk factors and implementing interventions to predict PTSD development.

RESUMO

The Locust Bean (Ceratonia siliqua L.) is an ancient Mediterranean fruit that is used to make locust bean gum from seeds, which is a popular ingredient in many foods today. Locust Bean fruit and Gum are rich in bioactive compounds that can be helpful in the treatment of conditions involving the digestive system, as well as cancer, hyperlipidemia, and diabetes. The locust bean gum is a polysaccharide extracted from the endosperm of the locust bean seed through different thermomechanical or chemical processes. It is an approved food additive with the European number E410 and a number of different food uses. It is a galactomannan and it is frequently used in dairy products for its water-binding and thickening properties to improve their rheological properties. This review aims to study the functional, and nutritional characteristics of Locust Bean Gum, the extraction of Locust Bean Gum, as well as its applications in the food sector and its impacts on dairy product processing.

RESUMO

Gastric cancer (GC) ranks as the fifth most prevalent cancer and the fourth deadliest cancer worldwide. In the Middle East and North Africa (MENA) region, GC represents about 4.8% of cancer cases with more than 35,000 new cases in 2020. To strengthen and improve the management of this cancer in the region, a group of MENA experts in the field of GC developed the first MENA consensus recommendations for the management of advanced GC. A total of 28 statements were drafted, discussed and voted on, using a modified Delphi process, during a virtual consensus meeting. The statements addressed the areas of epidemiology, biomarkers and treatment.

RESUMO

BACKGROUND: High academic achievement, an important determinant of future success, is known to be influenced by many factors including dietary behavior, lifestyle and mental health, among others. The objectives of the current study were to explore university students' nutritive habits, daily lifestyle, and mental status, and to scrutinize the associations between these factors and students' academic achievement. METHODS: A cross-sectional study was conducted among students of a private Lebanese university, using an electronic survey. Diet, eating habits, physical activity, sleep, and smoking were evaluated, and mental health was assessed using a validated Arabic version of the combined Depression, Anxiety, Stress Score (DASS-8). Academic achievement was measured using the Subjective Academic Achievement Scale (SAAS). RESULTS: A total of 1677 students participated in the questionnaire. The results of a linear regression taking the SAAS score as the dependent variable, showed that students who have a non-scientific versus scientific major (Beta = 0.53), and having breakfast ≥ 4 days per week compared to less than 2 days (Beta = 0.28) were significantly associated with higher SAAS scores. More psychological distress (Beta = - 0.06) and a higher number of days of eating out (Beta = - 0.07) were significantly associated with lower SAAS scores. CONCLUSIONS: This is the first investigation on a Lebanese university students' academic success in relation to lifestyle and mental profiles. Better academic achievement was demonstrated by students having healthier dietary and lifestyle habits, as well as less distressing mental status. Such results, in light of the compounded and unprecedented crises with which Lebanon has been assailed, suggest the need to focus on promoting healthy habits among students in higher education as a possible driver of better academic success.

RESUMO

INTRODUCTION: The COVID-19 pandemic is a serious threat to everyone's health. Numerous studies have demonstrated that vaccines are very effective in preventing COVID-19-related severe illness, hospitalization, and death. Children's vaccination exerts its protecting effect by preventing the spread of the virus. The purpose of this study was to analyze the rate of COVID-19 immunization among Lebanese children aged 1 to 11 years and assess parental factors that affect immunization rates. METHODS: An online cross-sectional study was conducted between January and March 2023. The online survey was distributed across all social media channels, including the Ministry of Public Health website. RESULTS: A total of 390 parents filled the survey (mean age = 37.48 ± 8.39 years; 50.5% mothers; 70% with a university level of education). Mothers compared to fathers, having a history of bad reaction to a vaccine vs. not, and higher vaccine hesitancy were significantly associated with less willingness to administer the vaccine to the child. Trusting pharmaceutical companies was significantly associated with more willingness to administer the vaccine to the child. CONCLUSION: The results of this study show that the factors associated with parents' decisions to vaccinate their children may vary. Our findings conclude that vaccine acceptance is being highly associated with parental concerns, trust, and information regarding the vaccine safety and efficacy.

RESUMO

Colorectal cancer (CRC) is ranked as the third most prevalent and the second deadliest cancer worldwide. In the Middle East and North Africa (MENA) region, the number of CRC cases increased over the past decades and will nearly double by 2030. The lack of clear MENA guidelines for the management of patients with CRC represents a step backwards in the fight against this burden. Therefore a panel of 24 MENA experts in the field of gastrointestinal oncology developed, using a Delphi process, the first consensus recommendations for the management of patients with advanced CRC. Forty-seven different statements were formulated in the areas of epidemiology, screening, biomarkers and treatment. These recommendations will guide, standardize and unify the management of this cancer in the MENA region.

RESUMO

BACKGROUND: Burnout (BO) among oncology professionals (OP) is increasingly being recognized. Early recognition and intervention can positively affect the quality of care and patient safety. This study investigated the prevalence, work and lifestyle factors affecting BO among OPs in the Middle East and North Africa (MENA). METHODS: An online survey was conducted among MENA OPs between 10 February and 15 March 2020, using the validated Maslach Burnout Inventory of emotional exhaustion (EE), depersonalization (DP) and personal accomplishment (PA), including questions regarding demography/work-related factors and attitudes towards oncology. Data were analysed to measure BO prevalence and risk factors and explore a screening question for BO. RESULTS: Of 1054 respondents, 1017 participants (64% medical oncologists, 77% aged less than 45 years, 55% female, 74% married, 67% with children and 40% practiced a hobby) were eligible. The BO prevalence was 68% with high levels of EE and DP (35% and 57% of participants, respectively) and low PA scores (49%). BO was significantly associated with age less than 44 years, administrative work greater than 25% per day and the thought of quitting oncology (TQ). Practising a hobby, enjoying oncology communication and appreciating oncology work-life balance were associated with a reduced BO score and prevalence. North African countries reported the highest BO prevalence. Lack of BO education/support was identified among 72% of participants and TQ-predicted burnout in 77%. CONCLUSIONS: This is the largest BO study in MENA. The BO prevalence was high and several modifiable risk factors were identified, requiring urgent action. TQ is a simple and reliable screening tool for BO.

RESUMO

Diabetes Mellitus develops when the body becomes unable to fuel its cells with glucose, which results in the accumulation of sugar excess in the bloodstream. Because it has diverse pathophysiological impacts on the body, diabetes mellitus represents a significant issue of concern in an attempt to find suitable treatment modalities and medications for afflicted diabetic patients. Glucagon-like peptide 1 (GLP-1) plays a pivotal role in the incretin effect, emerging as a prospective treatment for diabetes mellitus and a promising means of regenerating pancreatic cells, whether directly or through its receptor agonists. It has been shown that GLP-1 efficiently increases insulin production, lowers blood sugar levels in patients with type 2 diabetes mellitus, and decreases appetite, craving, and hunger, therefore amplifying the sensation of fullness and satiety. Moreover, since they are all dependent on GLP-1 effect, intricate signaling pathways share some similarities during specific phases, although the pathways continue to exhibit significant divergence engendered by specific reactions and effects in each organ, which encompasses the rationale behind observed differences. This triggers an expanding range of GLP-1 R agonists, creating new unforeseen research and therapeutic application prospects. This review aims to explain the incretin effect, discuss how GLP-1 regulates blood glucose levels, and how it affects different body organs, as well as how it transmits signals, before introducing selenium's role in the incretin impact.

RESUMO

Examining the microbiological characteristics of pet food is imperative to safeguard the health and well-being of companion animals, pet owners, and the surrounding environment. Domestic animals, known for carrying harmful microorganisms, pose a significant health risk, especially in close proximity to people and children. Notably, no studies have previously investigated pet food quality in the Gulf Cooperation Council countries, in particular, the United Arab Emirates (UAE). This study examined the microbiological quality of all stock keeping units (SKUs) of pet foods marketed in UAE (n = 118). Parameters assessed include Total Aerobic Microbial Count (TAMC), Enterobacteriaceae, Total Yeast and Mold Count (TYMC), Salmonella, Listeria monocytogenes, and Clostridium species. Among the 118 samples, 33 (28%) exceeded the acceptable TAMC limit of 106 CFU/g, highlighting significant variations based on manufacturers and ingredients. Eight samples (7%) surpassed the maximum Enterobacteriaceae limit of 3 × 102 CFU/g. TYMC levels exhibited variation, with 33 (28%) exceeding the limit of 104 CFU/g. L. monocytogenes was identified in 44 (37%) of the samples, while Salmonella was not detected. Clostridium contamination was observed in 28 (24%) of the samples. Statistical analyses revealed associations between pet food characteristics and microbial quality, underscoring the imperative for international standards to ensure the safety of pet food. These findings carry significant implications for pet owners, regulatory bodies, and the pet food industry, emphasizing the need for ongoing efforts to enhance the overall quality and safety of pet food products.

RESUMO

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.

RESUMO

Hydrolyzed collagen (HC) consists of many small and low-molecular-weight amino acid chains (3-6 kDa) that can be produced either in basic or acidic media through enzymatic activity. This review details the sources of hydrolyzed collagen, its biosynthesis and its uses in the food industry, as well as its production process and beneficial health effects. HC can be extracted from a variety of sources, during which acetic acid is used for the extraction of collagen type I from bovine, porcine, marine, chicken, and fish cartilage. An enzymatic treatment combined with an acidic treatment has shown more efficient extraction results. Because of its properties, it is frequently employed in the food industry since it improves sensorial qualities, as well as in the cosmetic industry as a functional component in face and body cream because of its moisturizing properties. It is also used in the pharmaceutical development of antioxidant supplements often combined with hyaluronic acid and vitamin C. HC has an excellent therapeutic effect on osteoporosis and osteoarthritis, where a daily dose of 12 g enhances pain symptoms and contributes to bone health. It also increases mineral density and protects articular cartilage. This review presents the structure and properties of hydrolyzed collagen, which mainly consists of the amino acids glycine, proline and hydroxyproline in a triple helix, its extraction process and its sources, as well as its applications. In particular, the creation of Enzymatic Membrane Reactor allows the production of HC with different molecular weight distributions, allowing wider application.

RESUMO

BACKGROUND: Acknowledging the increasing worry over climate change and its psychological effects, the aim of this research is to clarify the dynamics between religiosity, climate anxiety and death anxiety, seeking to figure out the way religiosity mitigates the psychological effects of existential anxieties and climate related anxiety. METHODS: Using Google Forms, a questionnaire was developed and disseminated through a variety of messaging platforms, such as WhatsApp, Instagram, and Facebook Messenger. Through a snowball sampling technique, 763 participants were recruited in this cross-sectional during September 2023. RESULTS: The subsequent variables were adjusted in the moderation analysis: age, gender, and place of living. The results suggested that religiosity levels moderated the association between climate anxiety and death anxiety (Beta = 0.02, t = 1.97, p = .05, 95% CI 0.001, 0.035). At low, moderate, and high levels of religiosity, higher climate anxiety was significantly associated with more death anxiety. In addition, at low levels of climate anxiety, individuals with higher levels of religiosity (22.66) had more decreased levels of death anxiety compared to those with lower levels of religiosity (11.99). As climate anxiety levels increase, inverted patterns can be observed, with highly religious individuals showing higher levels of death anxiety than those with lower levels of religiosity. Overall, the relationship between climate anxiety and death anxiety was found to be weakest at low levels of religiosity and strongest at high levels of religiosity. CONCLUSION: Our findings suggest a possible beneficial effect of high religiosity at low levels of climate anxiety. This effect is reversed as climate anxiety starts to increase. Therefore, clinicians and policy-makers should bear in mind these complex interactions when designing strategies to mitigate mental health problems in the context of climate crisis.

RESUMO

Owning pets offers various potential health benefits; however, it can be associated with gastrointestinal illnesses due to poor food safety knowledge and practices. This study aimed to evaluate the level of food safety knowledge and practices among pet owners in Lebanon, exploring the association between their knowledge/practices and socio-demographic characteristics. The participants included 300 pet owners, representing various genders, ages, educational levels, educational backgrounds, and incomes. They completed a questionnaire of 72 food handling practices and knowledge questions related to preparation, cross-contamination, storage and hygiene. In parallel, 300 non-pet owners with comparable sociodemographic characteristics to pet owners (control group) completed the questionnaire. On average, food safety knowledge scores were 62.1 ± 14.9% and 58.7 ± 15.5% among pet and non-pet owners, respectively, and the difference was significant (p = 0.05). On the other hand, mean food safety practice scores were 41.3 ± 14.8% and 40.4 ± 15.3% among pet and non-pet owners, respectively, and the difference was not significant (p = 0.41). In the food safety knowledge part, non-pet owners who were young, high income, university graduate, and from health-related majors scored significantly (p < 0.05) higher, while among pet-owners, only participants with a university degree and from health-related majors scored significantly (p < 0.05) higher, in terms of knowledge. On the other hand, In the food safety practices part, non-pet owners who were young, high income, and university graduates scored significantly (p < 0.05) higher, while among pet-owners, only young and high-income participants scored significantly (p < 0.05) higher. These results highlight the need for ongoing educational initiatives to improve food safety practices among both pet owners in Lebanon. The study suggests that targeted educational programs should be developed, considering specific socio-demographic characteristics, to enhance overall food safety awareness and practices among the population.

RESUMO

Overcoming the limited bioavailability and extensive metabolism of effective in vitro drugs remains a challenge that limits the translation of promising drugs into clinical trials. Resveratrol, despite its well-reported therapeutic benefits, is not metabolically stable and thus has not been utilized as an effective clinical drug. This is because it needs to be consumed in large amounts to overcome the burdens of bioavailability and conversion into less effective metabolites. Herein, we summarize the more relevant approaches to modify resveratrol, aiming to increase its biological and therapeutic efficacy. We discuss combination therapies, derivatization, and the use of resveratrol nanoparticles. Interestingly, the combination of resveratrol with established chemotherapeutic drugs has shown promising therapeutic effects on colon cancer (with oxaliplatin), liver cancer (with cisplatin, 5-FU), and gastric cancer (with doxorubicin). On the other hand, derivatizing resveratrol, including hydroxylation, amination, amidation, imidation, methoxylation, prenylation, halogenation, glycosylation, and oligomerization, differentially modifies its bioavailability and could be used for preferential therapeutic outcomes. Moreover, the encapsulation of resveratrol allows its trapping within different forms of shells for targeted therapy. Depending on the nanoparticle used, it can enhance its solubility and absorption, increasing its bioavailability and efficacy. These include polymers, metals, solid lipids, and other nanoparticles that have shown promising preclinical results, adding more "hype" to the research on resveratrol. This review provides a platform to compare the different approaches to allow directed research into better treatment options with resveratrol.

RESUMO

BACKGROUND: As climate change persists, accelerates, and intensifies, and since mitigating factors are absent, mental health impacts are expected to follow the same patterns. Therefore, it appears of utmost importance to deepen and broaden the knowledge and understanding of how and through which mechanisms climate change anxiety (CCA) may interplay with mental health outcomes. Based on the stress-vulnerability model of psychosis, the present study proposed to examine the relationship between CCA and psychotic experiences (PEs), and to test the theoretically-driven hypothesis that death anxiety acts as a mediator in this relationship. METHOD: This study adopted a cross-sectional approach involving a sample of young adults aged 18 to 35 years (mean age = 24.56 ± 22.49 years; 63.9% females) originating from, and residing in Lebanon. RESULTS: The results of the mediation analysis showed that death anxiety partially mediated the association between CCA and PEs. Higher CCA was significantly associated with higher death anxiety; higher death anxiety was significantly associated with more PEs. Finally, higher CCA was directly and significantly associated with more PEs. CONCLUSION: Drawing from the present preliminary findings, the key tentative recommendation is that addressing death anxiety might alleviate the association between CCA and PEs. In addition, government decision-makers need to recognize the necessity of considering climate change implications on mental health in policy and decision-making.
