RESUMEN

Since March 2020, the COVID-19 pandemic has swiftly propagated, triggering a competitive race among medical firms to forge vaccines that thwart the infection. Lebanon initiated its vaccination campaign on February 14, 2021. Despite numerous studies conducted to elucidate the characteristics of immune responses elicited by vaccination, the topic remains unclear. Here, we aimed to track the progression of anti-spike SARS-CoV-2 antibody titers at two-time points (T1: shortly after the second vaccination dose, T2: six months later) within a cohort of 201 adults who received Pfizer-BioNTech (BNT162b2), AstraZeneca, or Sputnik V vaccines in North Lebanon. Blood specimens were obtained from participants, and antibody titers against SARS-CoV-2 were quantified through the Elecsys-Anti-SARS-CoV-2 S assay (Roche Diagnostics, Switzerland). We used univariate analysis and multivariable logistic regression models to predict determinants influencing the decline in immune response and the occurrence of breakthrough infections among vaccinated patients. Among the 201 participants, 141 exhibited unchanging levels of antibody titers between the two sample collections, 55 displayed waning antibody titers, and only five participants demonstrated heightened antibody levels. Notably, age emerged as the sole variable significantly linked to the waning immune response. Moreover, the BNT162b2 vaccine exhibited significantly higher efficacy concerning the occurrence of breakthrough infections when compared with the AstraZeneca vaccine. Overall, our study reflected the immune status of a sample of vaccinated adults in North Lebanon. Further studies on a larger scale are needed at the national level to follow the immune response after vaccination, especially after the addition of the third vaccination dose.

RESUMEN

BACKGROUND: Lebanon has a high caesarean section use and consequently, placenta accreta spectrum (PAS) is becoming more common. OBJECTIVES: To compare maternal characteristics, management, and outcomes of women with PAS by planned or urgent delivery at a major public referral hospital in Lebanon. DESIGN: Secondary data analysis of prospectively collected data. SETTING: Rafik Hariri University Hospital (public referral hospital), Beirut, Lebanon. PARTICIPANTS: 159 pregnant and postpartum women with confirmed PAS between 2007-2020. MAIN OUTCOME MEASURES: Maternal characteristics, management, and maternal and neonatal outcomes. RESULTS: Out of the 159 women with PAS included, 107 (67.3%) underwent planned caesarean delivery and 52 (32.7%) had urgent delivery. Women who underwent urgent delivery for PAS management were more likely to experience antenatal vaginal bleeding compared to those in the planned group (55.8% vs 28.0%, p<0.001). Median gestational age at delivery was significantly lower for the urgent group compared to the planned (34 vs. 36 weeks, p<0.001). There were no significant differences in terms of blood transfusion rates and major maternal morbidity between the two groups; however, median estimated blood loss was significantly higher for women with urgent delivery (1500ml vs. 1200ml, p = 0.011). Furthermore, the urgent delivery group had a significantly lower birth weight (2177.5g vs. 2560g, p<0.001) with higher rates of neonatal intensive care unit (NICU) admission (53.7% vs 23.8%, p<0.001) and perinatal mortality (18.5% vs 3.8%, p = 0.005). CONCLUSION: Urgent delivery among women with PAS is associated with worse maternal and neonatal outcomes compared to the planned approach. Therefore, early referral of women with known or suspected PAS to specialized centres is highly desirable to maximise optimal outcomes for both women and infants.

RESUMEN

BACKGROUND: Developing countries have a significantly higher incidence of breast cancer in patients younger than 40 years as compared to developed countries. This study aimed to examine if young age at diagnosis is an independent prognostic factor for worse survival outcomes in breast cancer as well as the effect of age on Disease-free survival (DFS) and local recurrence free survival (LRFS) after adjusting for various tumor characteristics, local and systemic treatments. METHODS: This is a secondary analysis of prospective cohort of patients from two existing databases. We identified patients with breast cancer aged 40 years or less and we matched them to those older than 40 years. We also matched based on stage and molecular subtypes. In cohort 1, we matched at a ratio of 1:1, while in cohort 2 we matched at a ratio of 1:3. RESULTS: In cohort 1, Disease-free survival (DFS) at 5 years was significantly shorter for those younger than 40 years (75.6% and 92.7% respectively; p < 0.03). On multivariate analysis, only chemotherapy was found to be significant, while age was not found to be an independent predictor of prognosis. Local recurrence free survival at 5 years was similar between both age categories. Only hormonal therapy is a significant predictor for LRFS at 5 years. In the second cohort, DFS and LRFS at 3 years were similar between those younger and those older than 40 years. On multivariate analysis, no factor including age was found to be an independent predictor of prognosis. CONCLUSION: Data in the literature is controversial on the effect of young age on breast cancer prognosis. Our findings could not demonstrate that age is an independent prognostic factor in our population. There is a need for outcomes from larger, prospective series that have longer follow-ups and more data from our region.

RESUMEN

Research has identified both nonmodifiable and modifiable risk factors for breast cancer (BC), with accumulating evidence showing that adopting adequate dietary practices could decrease the risk of this disease. This study aimed to assess nutrition knowledge, attitudes, and lifestyle practices (KAP) that may lead to BC risk reduction among female university students in Lebanon and examine the determinants of their practices. A cross-sectional survey was conducted using a convenience sampling method, comprising 356 (response rate: 71.2%) female students at the American University of Beirut aged 18 to 25 years with no history of BC. Participants completed a pre-tested questionnaire addressing the objectives of the study. The modified Bloom's cut-off of 75% was used to categorize knowledge and practice scores as poor or good and attitudes as negative or positive. Large proportions of students had poor knowledge (68.3%), negative attitudes (65.4%), and poor practices (98.0%) scores. Pursuing a health-related major and having a higher GPA were associated with better knowledge and attitudes while being older and having a lower degree of stress were associated with positive attitudes only. Having a lower body mass index (BMI) was associated with better practice scores. Better knowledge significantly predicted higher intake of fruits and vegetables. Overall knowledge and attitudes were significantly correlated with each other, but neither was significantly correlated with overall practice. These findings underscore the importance of implementing public health programs geared towards improving nutrition KAP that may lead to BC risk reduction.

RESUMEN

Late presentation to medical care of individuals infected with the human immunodeficiency virus (HIV) is linked to poor outcomes and increased morbidity and mortality. Missed opportunities for a prompt diagnosis are frequently reported among late presenters. We aimed to estimate the proportion of late presenters and missed opportunities in diagnosis among newly diagnosed HIV-positive subjects presenting to a specialty clinic in Lebanon. This is a retrospective chart review of all newly diagnosed adult HIV-positive subjects presenting to clinic from 2012 to 2022. Demographic, laboratory, and clinical data were collected at initial HIV diagnosis or presentation to medical care. We defined late presentation as having a CD4 count < 350 or AIDS-defining event regardless of CD4 count. Advanced disease is defined as having a CD4 count below 200 cells/µL or the presence of an AIDS-defining illness, regardless of the CD4 count. A missed opportunity was defined as the presence of an indicator condition (IC) that suggests infection with HIV/AIDS during 3 years preceding the actual HIV diagnosis and not followed by a recommendation for HIV testing. The proportions for demographic, epidemiological, and clinical characteristics are calculated by excluding cases with missing information from the denominator. Our cohort included 150 subjects (92.7% males; 63.6% men who have sex with men (MSM); 33.3% heterosexuals; median age 30.5 years at diagnosis). 77 (51.3%) were late presenters and 53 (35.3% of all subjects, 68.8% of late presenters) had advanced HIV on presentation. Up to 76.5% of late presenters had a presentation with an HIV-related condition at a healthcare provider without getting HIV test within the previous 3 years. The most frequent ICs were weight loss, generalized lymphadenopathy, constitutional symptoms, and chronic idiopathic diarrhea. Overall mortality rate was 4% (6/150 individuals). All-cause mortality among those who presented with AIDS was 15.4% (6/39 subjects). In our setting, late presentations and missed opportunities for HIV diagnosis are common. In the Middle East, AIDS mortality remains high with a large gap in HIV testing. To effectively influence policies, comprehensive analyses should focus on estimating the preventable health and financial burdens of late HIV presentations. Another concern pertains to healthcare providers' attitudes and competencies.

RESUMEN

Alzheimer's disease (AD) is a neurodegenerative condition that displays a high prevalence in Lebanon causing a local burden in healthcare and socio-economic sectors. Unfortunately, the lack of prevalence studies and clinical trials in Lebanon minimizes the improvement of AD patient health status. In this review, we include over 155 articles to cover the different aspects of AD ranging from mechanisms to possible treatment and management tools. We highlight some important modifiable and non-modifiable risk factors of the disease including genetics, age, cardiovascular diseases, smoking, etc. Finally, we propose a hypothetical genetic synergy model between APOE4 and TREM2 genes which constitutes a potential early diagnostic tool that helps in reducing the risk of AD based on preventative measures decades before cognitive decline. The studies on AD in Lebanon and the Middle East are scarce. This review points out the importance of genetic mapping in the understanding of disease pathology which is crucial for the emergence of novel diagnostic tools. Hence, we establish a rigid basis for further research to identify the most influential genetic and environmental risk factors for the purpose of using more specific diagnostic tools and possibly adopting a local management protocol.

RESUMEN

After the beginning of the Syrian crisis, increased rates of infectious diseases were reported. Lebanon, a neighboring country with a major socioeconomic crisis, witnessed a measles outbreak since July 2023, with 519 reported suspected cases. Half of the cases were under 5 y of age, most of them were unvaccinated. The mass displacement of refugees from conflict areas in Syria to Lebanon and the low vaccination coverage have made the situation more challenging. Further efforts are required in Lebanon to address identified gaps to prevent or at least better control future outbreaks.

RESUMEN

OBJECTIVE: Refugees are frequently shown to have worse mental health outcomes than non-displaced populations. This fact is commonly attributed to traumatic pre-displacement experiences. While important, the focus on trauma risks overlooking the role socioeconomic living-conditions in different arrival and transit contexts can play in determining refugees' mental distress. Building on the ecological model of refugee distress, we investigate how social ecological conditions relate to the mental distress of Syrians in Lebanon and Turkey. Both countries present important spaces of arrival and transit for millions of displaced Syrians, each with a specific historical, political, social and economic context. METHODS: The empirical analysis is based on data gathered in early 2021 in face-to-face surveys among displaced Syrians in Lebanon (N = 1127) and Turkey (N = 1364). Individual mental distress is evaluated using the Patient Health Questionnaire (PHQ-8) score as the dependent variable in a multivariate regression analysis. RESULTS: Social ecological factors do not only differ in their extent of deprivation between Lebanon and Turkey. They also differ in their relationship with individual mental health outcomes. In Lebanon, limited access to the health care system and having family in the same city are major risk factors for elevated mental distress, whereas in Turkey, these are low education, poverty, unemployment as well as employment as day laborer. Discrimination and social isolation emerge as relevant predictors in both countries. CONCLUSION: Based on this analysis, we argue that a context-specific understanding of mental distress amidst the social ecology refugees face in countries of refuge and transit is necessary. This approach needs to be pursued to provide adequate support and alleviate refugees' mental distress both, in the country of first refuge and after possible onward migration. In addition to clinical implications, the study particularly highlights the important role anti-discrimination and social inclusion policies could play in promoting refugee mental health.

RESUMEN

The impact of conflict and crisis on maternal and child health underscores the need for reliable research in vulnerable populations. Lebanon, amidst ongoing economic collapse, political instability, and healthcare system strain, offers a case study for exploring these impacts, particularly on preterm babies and their development. This study aims to assess the feasibility of establishing a prospective cohort of mothers and their full-term and preterm babies in Lebanon, examining the association between social determinants, preterm birth, and developmental outcomes amidst the nation's multifaceted crises. The planned cohort involves 50 full-term and 50 preterm mother-baby pairs recruited at birth and followed up to 9-12 months post-birth. Data collection spans social determinants, perceived stress, social support, quality of life, and developmental assessments. Challenges in recruitment, follow-up, and data collection in the context of Lebanon's socio-political and economic turmoil are evaluated, alongside ethical considerations for research in vulnerable populations. Preliminary findings highlight substantial recruitment and follow-up challenges, notably due to population mobility, economic instability, and healthcare access issues. Despite these obstacles, 113 mother-baby pairs have been recruited. Early analysis reveals significant stress and reduced quality of life among mothers, particularly those with preterm infants, against a backdrop of declining birth rates and healthcare worker exodus. Conducting research in crisis settings like Lebanon presents unique methodological and ethical challenges but remains crucial for understanding and improving health outcomes in vulnerable populations. The study underscores the importance of adaptable research designs and ethical diligence in crisis research, highlighting the need for interventions tailored to these contexts. Establishing a mother and child cohort in Lebanon's crisis-ridden setting is faced with many challenges but is essential for guiding future interventions. Research in such contexts is needed to address health disparities and supporting vulnerable populations, emphasizing the need for dedicated funding and innovative research approaches in times of crisis.

RESUMEN

The occurrence of overweight and obesity among individuals with Autism Spectrum Disorder (ASD) has become a worldwide epidemic. However, there is limited research on this topic in the Lebanese population. Therefore, this study aimed to assess the differences in anthropometric measurements and body composition variables among Lebanese children, pre-adolescents, and adolescents diagnosed with ASD in contrast to typically developing peers across various developmental stages. Additionally, it aimed to investigate the prevalence of overweight and obesity within this population. A total of 86 participants with ASD and 86 controls were involved in this case-control study, conducted between June 2022 and June 2023. Anthropometric measurements and body composition variables were assessed, followed by statistical analyses to examine the differences between these two groups. The results revealed a significantly higher prevalence of overweight and obesity among individuals with ASD, particularly evident during childhood and pre-adolescence. Additionally, this group exhibited a higher body fat mass and total body fat percentage compared to controls. However, there were no significant differences observed between the two groups during adolescence. These findings emphasize the significance of monitoring and addressing weight status in individuals with ASD to improve their overall health outcomes. Future research directions could focus on investigating the underlying mechanisms contributing to the heightened prevalence of overweight and obesity in this population, ultimately enhancing their quality of life and well-being.

RESUMEN

BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) are the most common device-associated healthcare-acquired infections and pose a significant burden on patients and healthcare systems worldwide. However, there is a paucity of data on CAUTI epidemiology and microbiology in the Middle East and North Africa (MENA) region, including Lebanon. METHODS: This 14-year retrospective cohort study was conducted at a tertiary care center in Lebanon. It analyzed data on all adult patients diagnosed with CAUTI between January 2009 and December 2022 in intensive care units (ICUs) and between June 2011 and December 2022 in regular units. Incidence rates, urinary catheter utilization ratios, and microbiological profiles were collected and analyzed. RESULTS: A total of 620 CAUTI cases were identified during the study period. The overall CAUTI rate was 2.4 per 1000 catheter-days, with higher rates in ICUs (3.2 per 1000 catheter-days) compared to regular units (1.4 per 1000 catheter-days). No significant changes in the rates were noted despite implementing many interventions. The most common pathogens were Gram-negative bacteria, with Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae being predominant. Multidrug-resistant organisms represented 48% of all isolates. Enterobacterales were largely extended-spectrum ß-lactamase (ESBL) producing, and most Acinetobacter baumannii isolates showed multidrug resistance. CONCLUSIONS: This study provides important insights into CAUTI epidemiology and microbiology in a tertiary care center in Lebanon, addressing the knowledge gap in this area in the MENA region. Despite implementing prevention measures, CAUTI rates remained stable over the 14-year period. The findings highlight the need for continuous improvement in infection prevention practices, diagnostic stewardship, and antimicrobial stewardship, especially given the rising threat of antimicrobial resistance. These results can serve as a guide for the development of targeted preventive strategies to reduce the burden of CAUTIs, particularly in low- and middle-income countries where antimicrobial resistance is a major issue.

RESUMEN

Acute diarrhea is a prevalent disease worldwide and a cause of mortality in low and middle-income countries. In previous studies, the causative enteropathogen is found in 38% to 58% of patients, leaving a considerable diagnostic gap. In this study, we intend to determine the pathogenic agents responsible for acute diarrhea in patients presenting to the Emergency Departments of several Lebanese hospitals. A total of 100 stool samples were collected between June 2022 and June 2023 from patients presenting with acute diarrhea to the Emergency Departments. Pathogens were detected by multiplex polymerase chain reaction. The average age for the patients was 53 years old. All patients presented with diarrhea, 15 of them had fever associated. In total, 46 patients were admitted to the hospital (70%), among them 80% received Intravenous antibiotics. Campylobacter was the most common agent detected in 36%, followed by Rotavirus 19%, and Noroviruses 15%. The rest was detected at lower percentages. Bacteria accounted for 49% of cases, viruses for 39%, and parasitic infection 6%. Acute diarrhea epidemiology is understudied in Lebanon. This study is the first Lebanese data about acute diarrhea pathogens. Avoiding overuse of antibiotics in bacterial versus viral infections can be achieved while prevention campaigns can raise awareness about food and water safety at the community level.

RESUMEN

OBJECTIVES: Evidence on non-communicable disease (NCD) prevalence and associated risk factors informs primary health care consolidation regarding prevention and treatment strategies. In Lebanon, the government and many international organisations are still working to decrease the burden of NCDs. The aim of this study was to assess the prevalence of selected NCDs and their risk factors among adults in Lebanon, and to investigate the relationship between these risk factors and NCDs. STUDY DESIGN: A multicentric cross-sectional study was conducted over one year, from 1 June 2022 to 31 June 2023, across five Lebanese governorates. METHODS: Participants aged ≥18 years were considered eligible for enrolment in the study. Data on the sociodemographic, behavioural and medical characteristics of participants were collected. RESULTS: From the total study population (n = 4540), 52.4% reported one or more NCDs. The prevalence of most prominent NCDs were hypertension (32.8%), diabetes (26.8%), cardiovascular disease (16.1%), asthma (7.1%) and cancer (3.7%). Results showed a significant association between gender and smoking, high-fibre diet and asthma (P-value <0.05). Findings showed a highly significant association between age categories and smoking, high-fibre diet, physical activity, diagnosis with NCDs, hypertension, diabetes and cardiovascular disease (P-value <0.0001). CONCLUSIONS: This study showed a high prevalence of NCDs among adults living in Lebanon. Prevention, treatment and control of NCDs and their risk factors are a public health priority in Lebanon, and resources are required to provide targeted interventions with a multisectoral approach.

RESUMEN

OBJECTIVES: The objective of the study is to investigate the effects of the COVID-19 pandemic, the economic crisis and the Beirut explosion on the training and work of ophthalmology residents and faculty in Lebanon. DESIGN: This is an observational cohort survey-based research conducted between January and December 2022. SETTING: The study targeted all ophthalmology residents and core faculty in Lebanon. PARTICIPANTS: A total of 52 participants, including 27 residents and 25 core faculty members, completed the survey. PRIMARY OUTCOME MEASURE: Primary outcomes comprised the subjectively reported effect of the three major external stressors on the training and well-being of ophthalmology trainees and educators in Lebanon. RESULTS: The study found that the majority of ophthalmology residents and core faculty members were significantly affected by the COVID-19 pandemic, Beirut explosion and the economic crisis in Lebanon. Significant percentage reported financial burden, decrease in outpatient and surgical load and educational activities. Furthermore, most participants reported higher levels of stress, anxiety and depression during the time of crises. CONCLUSIONS: This study emphasises the need to support healthcare professionals during times of crisis, as they are on the frontlines and can experience high levels of stress, anxiety and depression. By providing support and resources to healthcare professionals, they can better cope with the challenges they face and continue to provide essential care to their patients.

RESUMEN

BACKGROUND: Refugee populations present with high levels of psychological distress, which may vary among sociodemographic characteristics. Understanding the distribution across these characteristics is crucial to subsequently provide more tailored support to the most affected according to their specific healthcare needs. This study therefore seeks to investigate the association between pre-migration socioeconomic status (SES) and post-migration mental health separately for male and female Syrian refugees in Lebanon. METHODS: In a cross-sectional study, a cluster randomized sample of 599 refugees from Syria were recruited between 2016 and 2019 within 12 months after they fled to Lebanon. Logistic regression was used to determine the association between self-reported pre-migration SES and levels of anxiety and depressive symptoms assessed on the Hopkins Symptoms Checklist-25 (HSCL-25) scale, both for the entire sample and stratified by sex. To assess the informative value of self-reported SES, its correlation with education variables was tested. All analyses were conducted in R version 4.3. RESULTS: Using complete cases, 457 participants (322 female, 135 male) were included in the analyses. Females showed on average more symptoms of anxiety (Median: 2.5) and depression (Median: 2.4) than males (Median: 2.10 and 2.07, respectively). Below average SES was associated with significantly higher odds for mental illness compared to average SES (anxiety: OR 4.28, 95% CI [2.16, 9.49]; depression: OR 1.85, 95% CI [1.06, 3.36]). For anxiety, differences between SES strata were larger for males than females. The self-reported SES measure showed only a weak positive correlation with education. CONCLUSIONS: This study adds additional descriptive data highlighting mental health differences in Syrian refugees in Lebanon, whereby below average SES is associated with worse mental health outcomes compared to average SES. These findings demand further research into the underlying mechanisms. Improving our understanding of the observed differences will provide valuable insights that can contribute to the future development of targeted measures.

RESUMEN

BACKGROUND: Granulosa Cell Tumors (GCT) are considered the most frequent type of sex-cord stromal tumors. These tumors constitute 3-6% of neoplasms of the ovaries. GCTs are divided into 2 types: Juvenile GCT (JGCT) and Adult GCT (AGCT). Most patients are diagnosed early in the course of the disease and tend to have a favorable prognosis. In the surgical treatment of GCT, two main factors play role in the determination of feasibility of the surgery: age and tumor stage. METHODS: A retrospective study was conducted on 65 consecutive female patients diagnosed with ovarian GCT at different hospitals across Lebanon who were referred to the National Institute of Pathology, Beirut-Lebanon, between January 2000 and January 2020. Then, they were divided according to types: adult versus juvenile type. Statistical analysis was carried out using Stata, version 16. RESULTS: The incidence of GCT in a Lebanese population was 16.2 per million per year. The mean age of the studied population was 55.6 years. AGCT was the most common with a prevalence of 91% versus 19% for JGCT. Also, inhibine (the most important immunomarker) was found in 77.2% of adult cases. High mitotic index and high tumor size which are predictors for poor prognosis were respectively 20% and 36.9%. Concerning the histopathological features, Grooved nuclei and Exner bodies were less frequently observed in juvenile type (16.7% for both) compared to adult type (36.9%). Most patients with GCT were diagnosed in the early course of disease mainly due to the manifestation of the symptoms as abdominal pain, postmenopausal bleeding or intermenstrual bleeding, and the good diagnosis and screening practices in Lebanon. Regarding the recurrent cases, a significant correlation with high mitotic index (76.9%), high tumor size (92.3%) and advanced stage (46% for stage 3 and 46% for stage 4) was found with a p < 0.05. CONCLUSIONS: The incidence of GCT in the Lebanese population is 16.2 per million per year. The majority of patients with GCT in Lebanon are of Adult type representing around 90% of cases. Older age, high mitotic index and big tumor size are predictors for poor outcomes.

RESUMEN

BACKGROUND: Infectious agents associated with community-acquired acute respiratory infections (ARIs) remain understudied in Lebanon. We aim to assess the microbiological profiles of ARIs by employing polymerase chain reaction (PCR) and identifying predictors of positive PCR results among patients admitted for ARI. METHODS AND RESULTS: We conducted a retrospective single-center study at the American University of Beirut Medical Center, including all respiratory PCR panels performed on pediatric (< 18) and adult (≥ 18) patients presenting with an ARI from January 2015 to March 2018, prior to the onset of the COVID-19 pandemic. We aimed to identify the epidemiological patterns of ARIs and the factors associated with positive PCRs in both adult and pediatric patients. Among 281 respiratory PCRs, 168 (59.7%) were positive for at least one pathogen, with 54.1% positive PCR for viruses, 7.8% for bacteria species, and 3.9% with virus-bacteria codetection. Almost 60% of the patients received antibiotics prior to PCR testing. PCR panels yielded more positive results in pediatric patients than in adults (P = 0.005). Bacterial detection was more common in adults compared to pediatrics (P < 0.001). The most common organism recovered in the entire population was Human Rhinovirus (RhV) (18.5%). Patients with pleural effusion on chest CT were less likely to have a positive PCR (95% Cl: 0.22-0.99). On multivariate analysis, pediatric age group (P < 0.001), stem cell transplant (P = 0.006), fever (P = 0.03) and UTRI symptoms (P = 0.004) were all predictive of a positive viral PCR. CONCLUSION: Understanding the local epidemiology of ARI is crucial for proper antimicrobial stewardship. The identification of factors associated with positive respiratory PCR enhances our understanding of clinical characteristics and potential predictors of viral detection in our population.

RESUMEN

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.

RESUMEN

BACKGROUND: Although prostate cancer is a prevalent malignancy worldwide, its clinical presentation and management in the Middle East are not well-documented. This study aims to provide insights into the initial clinical presentation and management of prostate cancer in this region. METHODS: A retrospective review was conducted on seven institutional databases from six Middle Eastern countries, including Türkiye, Lebanon, Iraq, Syria, Bahrain, and Jordan, to identify patients diagnosed with prostate cancer in 2021. Descriptive analysis was performed on the collected data to provide an overview of the demographic, clinical, and treatment variables. RESULTS: A total of 1,136 patients were identified with a median age of 70 (range, 50-84). Most patients (78%) received their prostate cancer diagnosis after presenting with symptoms, as opposed to routine PSA screening. At the time of diagnosis, 35% of men had clinical T3 or T4 disease, 54% with Stage IV disease and 50% with Gleason score ≥ 8. Regarding treatment, 20% of non-metastatic and 22% of metastatic patients received no treatment. CONCLUSION: Most men in this study sought prostate cancer evaluation due to symptoms and were subsequently diagnosed with advanced-stage disease, providing a foundation for future research aimed at understanding the underlying factors behind the observed trends and enabling informed interventions.
