RESUMEN
This retrospective study investigates the prevalence of atypical femoral fractures (AFFs) among patients admitted with hip and shaft fractures at a tertiary referral center in Beirut, Lebanon. We analyzed electronic medical records and radiology studies of patients aged above 40 admitted with hip and shaft fractures between January 2006 and December 2019. Fractures were confirmed by ICD9 or ICD10 codes. All cases were reviewed by radiologists, and AFFs were identified according to the 2013 revised ASBMR criteria. We identified 1366 hip and shaft fracture patients, of which 14 female patients had 19 AFFs. This represents a prevalence of 1.0% among all hip and shaft fractures patients and 1.7% among all female hip and shaft fracture patients. Bilateral AFFs were found in 5 of the 14 patients. Patients with AFF tended to be younger, with a mean age of 74.3 (±8.6) yr compared to 78.0 (±10.6) for patients with non-AFF fractures. A total of 36% of AFF patients had a prior history of non-traumatic fracture at first admission. A high percentage of patients with AFFs reported intake of proton pump inhibitors (42.9%) and glucocorticoids (21.4%). Bisphosphonate exposure was noted in 64.3% of AFF patients. None of the AFF patients were active smokers or consumed alcohol regularly. BMD assessments were available for 7 AFF patients, indicating osteoporosis in 4 and osteopenia in 3 cases. Hip axis length measurements showed no significant difference between AFF patients (N = 7) and sex and age-matched controls (N = 21). The study underlines the prevalence and characteristics of AFFs in Lebanon, which is consistent with the numbers reported in the literature (0.32%-5%). A larger prospective study that includes hospitals across the nation is needed to gain a more comprehensive view of the prevalence of AFFs in the Lebanese population.
RESUMEN
Background: The global epidemic of noncommunicable diseases (NCDs) is increasing. Current assessments that monitor capacity to address NCDs are often externally led and do not facilitate country planning. The Noncommunicable Disease Capacity Assessment and Planning (N-CAP) Process assists ministries of health and other governmental and non-governmental stakeholders to assess, prioritize, and plan how to address NCDs and other public health threats. This paper describes the development of this tool. Materials and methods: Driven by ministries of health, the N-CAP Process engages new and existing stakeholders in three activities: Stakeholder Mapping; Strengths, Weaknesses, Opportunities, and Threats Workshop; and N-CAP Workshop that uses Discussion Guides to lead in-depth assessment and planning. Standard Operating Procedures, a library of Discussion Guides based on common NCD themes, and an open-access e-learning course are available. Results: The N-CAP Process outcome is a prioritized plan of how to improve the country's public health functions. Adaptations to the tool were made after piloting in Jordan and Iraq. Conclusion: The N-CAP Process helps countries engage various stakeholders to identify gaps and create collaborative, country-specific strategies to effectively respond to NCDs, a leading public health threat. The pilots sparked interest from other countries and underscored its potential for broader implementation to combat the rising global burden of NCDs.

The COVID-19 transmission in the Eastern Mediterranean Region (EMR) was influenced by various factors such as conflict, demographics, travel and social restrictions, migrant workers, weak health systems, and mass gatherings. The countries that responded well to COVID-19 had high-level political commitment, multisectoral coordination, and existing infrastructures that could quickly mobilize. However, some EMR countries faced challenges due to political instability and fragile health systems, which hindered their response strategies. The pandemic highlighted the region's weak health systems and preparedness, fragmented surveillance systems, and lack of trust in information sharing. COVID-19 exposed the disruption of access and delivery of essential health services as a major health system fragility. In 2020, the World Health Organization (WHO) conducted a global pulse survey, which demonstrated that the EMR experienced the highest disruption in health services compared to other WHO regions. However, thanks to prioritization by the WHO and its member states, significant improvement was observed in 2021 during the second round of the WHO's National Pulse Survey. The pandemic underscored the importance of political leadership, community engagement, and trust and emphasized that investing in health security benefits everyone. Increasing vaccine coverage, building regional capacities, strengthening health systems, and working toward universal health coverage and health security are all priorities in the EMR. Emergency public health plays a key role in preparing for and responding to pandemics and biological threats. Integrating public health into primary care and investing in public health workforce capacity building is essential to reshaping public health and health emergency preparedness.

Background: There is a paucity of data on Healthcare Providers (HCPs) caring for people living with HIV in Jordan. Objective: We aimed to understand HCPs' knowledge, attitude, stigma, and practices, to assess the gaps in HIV care in Jordan. Methods: We conducted recorded in-depth interviews with all five HCPs working at the only HIV Service Center in Jordan, using semi-structured questions in 2021. Content analysis was performed. Results: Several organizational challenges were identified. Only one had received HIV training. All were uncertain of updated recommendations with little knowledge of international guidelines, vertical transmission, contraception, sexually transmitted infections (STIs), non-communicable diseases (NCDs), and prophylaxis. Four HCPs perform counseling, focusing on easing anxieties, risk modification, and the importance of treatment adherence. However, their counseling on contraception, risk of transmission, STIs, and NCDs is inadequate, and they have little-to-no experience with prophylaxis. Most had a positive attitude towards people living with HIV, especially HCPs working at the center the longest, encouraging marriage and reproduction. Most do not approve of mandatory testing, or of breaching patient confidentiality. They repetitively described risky behavior as 'immoral behavior', empathizing more with patients who caught HIV through blood transfusion or birth, and demonstrating embedded stigmatized beliefs. They reported people living with HIV experience anticipated stigma and stigma by their general community including by other HCPs. Conclusion: This is the first study on HCPs caring for people living with HIV in Jordan. It highlights the suboptimal knowledge, practices, and stigma which improve with greater participatory exposure to HIV care. HCPs had an overall positive attitude, more evident in HCPs working at the clinic the longest.
RESUMEN
Achieving Universal Health Coverage (UHC) is a strategic objective of the Jordanian government and has been prioritized in its strategies and plans. However, there are several challenges affecting primary healthcare in Jordan and the health system in general that prevent Jordan from achieving UHC. This paper highlights the importance of team-based care in the form of Family Health Teams (FHTs) to realize Jordan's goal of achieving UHC. FHTs are a team-based approach that brings together diverse professionals to provide a comprehensive, efficient, patient-centered primary care system that meets the changing needs of Jordan's population and refugees. However, the implementation of FHT may encounter obstacles, including individual, organizational, institutional, and external barriers. To overcome such obstacles, several actions and processes need to be taken, including political commitment and leadership, implementing good governance and policy frameworks, allocating resources and funding, multisectoral collaboration, and engagement of communities and stakeholders. The successful implementation of FHTs requires participation from government officials, parliamentarians, civil society, and influential community, religious, and business leaders. A strategic policy framework, effective oversight, coalition building, regulation, attention to system design, and accountability are also essential. In conclusion, adopting the FHT approach in Jordan's Primary Healthcare system offers a promising path towards achieving UHC, improving healthcare access, quality, and efficiency while addressing the unique challenges faced by the country's healthcare system.
RESUMEN
Public health research plays a critical role in strengthening health systems and improving their performance and impact. However, scholarly production in public health coming from the Eastern Mediterranean Region (EMR) remains well below the world average and lacks a tangible growth trend over time. During the seventh Eastern Mediterranean Public Health Network Regional Conference, a roundtable session brought together a panel of public health experts representing Global Health Development/Eastern Mediterranean Public Health Network affiliates, universities or academia, and research institutions from the region, where they shared insights on the current situation of public health research; challenges and barriers to research facing the different countries in the EMR and the region in general; and how research agendas, productivity, and quality can be supported through strengthening research capacity in the region. Although the region is diverse in terms of health system capacity and socioeconomic development, several common challenges were identified, including a lack of strategic prioritization to guide health research, insufficient funding, ineffective transfer of knowledge to policy and practice, limited availability of research facilities, and limited national and international research collaboration. Occupied countries and countries in a state of conflict, such as Palestine, face additional barriers, such as personal and social security, lack of control of borders and natural resources, travel and movement restrictions, and confidentiality challenges because of the continuing war conditions and occupation. However, there have been success stories in the EMR regarding research publications and their positive and effective impact on policy and decision-makers. To improve research resilience and public health care in the region, a collaborative approach involving institutions, policymakers, and relevant stakeholders is critical.
RESUMEN
Waterpipe tobacco smoking (WTS) is a traditional tobacco use method that originated in the Eastern Mediterranean Region (EMR) and has resurged in recent decades. WTS rates in the EMR are the highest worldwide, especially among youth, exceeding cigarette-smoking rates in select jurisdictions. Despite its documented harm, the growing prevalence of WTS has been met with a poor regulatory response globally. At the epicenter of the WTS epidemic, countries in the EMR are in urgent need of effective tobacco control strategies that consider the particularities of WTS. A roundtable session, titled "Monitoring and Combating WTS Through Taxation and the Global Tobacco Surveillance System (GTSS)," was held as part of the 7th Eastern Mediterranean Public Health Network's regional conference. The session provided an overview of evidence to date about WTS policy control, the taxation of WTS, volumetric choice experiments for tobacco control research, and monitoring WTS patterns and control policies among adults and youth through the GTSS. The session highlighted the need to update the regulation of WTS in the current global tobacco control policy frameworks and the need for developing tailored, evidence-based, and WTS-specific regulations to complement current tobacco control policy frameworks. Raising taxes to increase the price of tobacco products is the single most effective tobacco control measure, and these taxes can fund expanded government health programs. The effectiveness of taxation can be measured via volumetric choice experiments, which allow for the estimation of a complete set of own-price and cross-price elasticities that are instrumental for fiscal policy simulations. Finally, the surveillance of WTS (for example, through the GTSS) is critical to informing policy and decision makers. The Global Youth Tobacco Survey (GYTS) and Global Adult Tobacco Survey (GATS) are 2 GTSS products that provide nationally representative data among students aged 13-15 years and persons ≥15 years, respectively.

Introduction: Increased abdominal visceral adipose tissue (VAT) implies an adverse cardio-metabolic profile. We examined the association of abdominal VAT parameters and all-cause mortality risk. Methods: We systematically searched four databases. We performed citations/articles screening, data abstraction, and quality assessment in duplicate and independently (CRD42020205021). Results: We included 12 cohorts, the majority used computed tomography to assess abdominal VAT area. Six cohorts with a mean age ≤ 65 years, examining all-cause mortality risk per increment in VAT area (cm2) or volume (cm3), showed a 11-98% relative risk increase with higher VAT parameters. However, the association lost significance after adjusting for glycemic indices, body mass index, or other fat parameters. In 4 cohorts with a mean age >65 years, the findings on mortality were inconsistent. Conversely, in two cohorts (mean age 73-77 years), a higher VAT density, was inversely proportional to VAT area, and implied a higher mortality risk. Conclusion: A high abdominal VAT area seems to be associated with increased all-cause mortality in individuals ≤ 65 years, possibly mediated by metabolic complications, and not through an independent effect. This relationship is weaker and may reverse in older individuals, most likely secondary to confounding bias and reverse causality. An individual participant data meta-analysis is needed to confirm our findings, and to define an abdominal VAT area cutoff implying increased mortality risk.

BACKGROUND: The challenges presented by the COVID-19 pandemic have led to unprecedented global research activity. The Eastern Mediterranean Region (EMR) continues to contribute to COVID-19 research driven by the unique challenges of the region, including the protracted conflicts, already stressed health systems, and serious health and social inequalities. OBJECTIVE: This study aims to provide an overview of the publication activities and trends in COVID-19 research in the EMR from the onset of the disease to early 2022 using bibliometric methods. METHODS: A literature search using Scopus was conducted from December 1, 2019, to January 31, 2022, using keywords relevant to COVID-19 and the World Health Organization (WHO) EMR country list. Data were exported and analyzed using Microsoft Excel and the Citation Overview function on Scopus. The quality of journals was determined using SCImago Journal Rank and CiteScore. VOSviewer software was used to visualize the relationships between authors, countries, and key terms used in the retrieved documents. RESULTS: A total of 6880 documents were retrieved, of which 1805 (26.24%) were from the Kingdom of Saudi Arabia (KSA) and 1782 (25.90%) from Iran, followed by Pakistan, Egypt, and Jordan. Most published documents were affiliated with EMR universities, primarily the Tehran University of Medical Sciences in Iran and King Saud University in KSA (396/6880, 5.76%, and 370/6880, 5.4%, respectively), while only 407 (5.92%) of 6880 documents were associated with universities outside the EMR. For most of the identified publications (5020/6880, 72.97%), no funding source was reported, while King Saud University contributed the largest share (282/1860, 15.16%) of funded publications. Retrieved documents were cited 53,516 times, with an average of 7.78 (SD 34.30). Iran was the EMR country with the most links to other countries (77 links and total link strength of 1279). The 5 authors with the most publications were from KSA, Qatar, and Jordan. There were 290 high-frequency keywords that occurred ≥10 times and were linked in 7 different clusters. The cluster with the most linked keywords was related to epidemiology and mortality. Recent topics included vaccines, vaccination, machine learning, and online learning. CONCLUSIONS: This is the first study to show trends in and project future developments of COVID-19 research activity in the EMR. Authors and institutions who led research on COVID-19 in the region were from Iran and KSA. There were multiple regional collaborative efforts; however, international collaboration was limited. Recently, interest has been shifting toward topics related to vaccination, machine learning, and online learning. Understanding the current state of research is instrumental to future research production, and our study will inform regional research initiatives on emerging concepts, as well as opportunities for collaboration and funding.
RESUMEN
BACKGROUND: The Eastern Mediterranean Region (EMR) hosts some of the world's worst humanitarian and health crises. The implementation of health surveillance in this region has faced multiple constraints. New and novel approaches in surveillance are in a constant state of high and immediate demand. Identifying the existing literature on surveillance helps foster an understanding of scientific development and thus potentially supports future development directions. OBJECTIVE: This study aims to illustrate the scientific production, quantify the scholarly impact, and highlight the characteristics of publications on public health surveillance in the EMR over the past decade. METHODS: We performed a Scopus search using keywords related to public health surveillance or its disciplines, cross-referenced with EMR countries, from 2011 to July 2021. Data were exported and analyzed using Microsoft Excel and Visualization of Similarities Viewer. Quality of journals was determined using SCImago Journal Rank and CiteScore. RESULTS: We retrieved 1987 documents, of which 1927 (96.98%) were articles or reviews. There has been an incremental increase in the number of publications (exponential growth, R2=0.80) over the past decade. Publications were mostly affiliated with Iran (501/1987, 25.21%), the United States (468/1987, 23.55%), Pakistan (243/1987, 12.23%), Egypt (224/1987, 11.27%), and Saudi Arabia (209/1987, 10.52%). However, Iran only had links with 40 other countries (total link strength 164), and the biggest collaborator from the EMR was Egypt, with 67 links (total link strength 402). Within the other EMR countries, only Morocco, Lebanon, and Jordan produced ≥79 publications in the 10-year period. Most publications (1551/1987, 78.06%) were affiliated with EMR universities. Most journals were categorized as medical journals, and the highest number of articles were published in the Eastern Mediterranean Health Journal (SCImago Journal Rank 0.442; CiteScore 1.5). Retrieved documents had an average of 18.4 (SD 125.5) citations per document and an h-index of 66. The top-3 most cited documents were from the Global Burden of Diseases study. We found 70 high-frequency terms, occurring ≥10 times in author keywords, connected in 3 clusters. COVID-19, SARS-CoV-2, and pandemic represented the most recent 2020 cluster. CONCLUSIONS: This is the first research study to quantify the published literature on public health surveillance and its disciplines in the EMR. Research productivity has steadily increased over the past decade, and Iran has been the leading country publishing relevant research. Recurrent recent surveillance themes included COVID-19 and SARS-CoV-2. This study also sheds light on the gaps in surveillance research in the EMR, including inadequate publications on noncommunicable diseases and injury-related surveillance.

PURPOSE: We investigated prevalence, determinants, seasonal changes, and time trends in hypovitaminosis D. We derived a desirable serum 25-hydroxy-vitamin D (25OHD) level in adults/elderly by evaluating the 25OHD-parathyroid hormone (PTH) exponential relationship. METHODS: We analyzed serum 25OHD data from a large laboratory database (Nâ¯=â¯151,705), from a major academic medical center in Lebanon, from 2009 to 2016. We used cross calibration formulas to convert measured 25OHD levels to LC-MS/MS equivalents based on our external quality assurance protocols. RESULTS: 6% of the population were children (mean age 11⯱â¯5â¯years, 56% girls), 68% were adults (44⯱â¯13â¯years, 71% women), and 25% were elderly (74⯱â¯6â¯years, 59% women). The prevalence of hypovitaminosis D, in the entire population, was 39%, 29% and 23% at 25OHD cutoffs of 20â¯ng/ml, 15â¯ng/ml, and 12â¯ng/ml, respectively, across all years. Using multivariate analysis, predictors of 25OHD levels below 12, 15 and 20â¯ng/ml were younger age, male sex, winter months, and inpatient status both in adults and elderly. In children, older age, female sex, winter months, and inpatient status, predicted levels below 15â¯ng/ml and 20â¯ng/ml, but only older age, female sex, and winter months predicted levels below 12â¯ng/ml. There was a significant steady annual increase in 25OHD levels between 2009 and 2016 of 0.9â¯ng/ml/year (95% CI: 0.7, 1.0) in children, 1.2â¯ng/ml/year (1.2, 1.3) in adults and 2.6â¯ng/ml/year (2.6, 2.8) in the elderly. Using best fit non-linear regression models, on a subset of adults and elderly in whom concomitant 25OHD and PTH data was available (Nâ¯=â¯4025), PTH levels plateaued at a serum 25OHD level of 26.1â¯ng/ml. CONCLUSION: Secular increase in serum 25OHD levels is observed in Lebanon, but hypovitaminosis D is still prevalent. Our data provides basis for a desirable 25OHD level above 26â¯ng/ml in adult and elderly Lebanese individuals.

Obesity rates are increasing rapidly, and bariatric surgery is currently the most effective tool for weight loss. Recently, bariatric surgery induced bone loss has gained attention. Such detrimental effect on bone is multifactorial and causes may include nutrient deficiencies, gut and gonadal hormonal changes, mechanical unloading, loss of lean mass, increased bone marrow fat, and increased risk of fall. This review describes the available evidence on bone loss and fracture risk following bariatric surgery and summarizes the guidelines on the topic. Increased bone resorption starts early postsurgery, and bone markers peak at 1-2 yr. Across studies, the drop in areal bone mineral density is inconsistent at the lumbar spine, while a 2%-5% drop at 6 mo and a 6%-10.5% at 9-12 mo are observed at the total hip. Conversely, studies using quantitative CT showed a 6%-7% decrease in volumetric bone mineral density at the lumbar spine at 6-12 mo postsurgery. These studies also report significant bone loss at the radius and tibia, in addition to alteration in bone microarchitecture. Fracture risk increases 2 yr after surgery, more so following malabsorptive procedures. Fractures were reported at axial, weight bearing sites and at appendicular sites. The available evidence is very heterogeneous, and mostly derived from studies on Roux-en-y gastric bypass in premenopausal women. Data on restrictive procedures is scarce. Our findings suggest that the early postoperative phase represents the "golden window" to intervene and promote bone health. More research is needed to determine the effect of different bariatric procedures on bone, to identify optimal interventions to prevent bone loss and to characterize high risk individuals who should be targeted.

Country-specific hip fracture incidence rates (IRs) and longevity allow the Fracture Risk Assessment Tool (FRAX) to be adapted to individual countries. Secular trends can affect tool calibration. Data on hip fracture IRs in the Middle East is scarce, and long-term secular trend studies are nonexistent. Using the Ministry of Public Health hip fracture registry, we calculated age- and sex-specific hip fracture IRs in Lebanon, from 2006 to 2017, among individuals aged ≥50 years. We used Kendall's tau-b (τb) test to determine the correlation between time and hip fracture IRs, and calculated both the annual % change in IRs and the % change in IR compared to the baseline period (2006 to 2008). The registry recorded 6985 hip fractures, 74% at the femoral neck, 23% intertrochanteric, and 3% subtrochanteric. Men constituted 32% of the population, and were significantly younger than women (76.5 ± 11.0 years versus 77.7 ± 10.3 years; p < 0.001). Annual overall IRs, per 100,000, ranged from 126.6 in 2014 to 213.2 in 2017 in women, and 61.4 in 2015 to 111.7 in 2017 in men. The average women to men IR ratio was 1.8 (range, 1.5 to 2.1). IRs steadily increased with age, and IR ratios increased in parallel in both sexes, with a steeper and earlier rise (by 5 years) in women. Data showed a consistent decline in hip fracture IRs starting in 2006 in women, and in 2009 in men. There was a significant negative correlation between time (2006 to 2014) and hip fracture IRs in women (τb = -0.611, p = 0.022) but not in men (τb = -0.444, p = 0.095). The steady decrease in IRs reversed after 2015 in both sexes. This long-term data on secular trends in the Middle East is novel and consistent with worldwide changes in hip fracture rates. The impact of such changes on national FRAX-derived estimates is unclear, should be assessed, and may necessitate an update in the FRAX Lebanon calculator. © 2019 American Society for Bone and Mineral Research.

OBJECTIVE: To assess characteristics of patients with hip fractures and investigate the extent of osteoporosis-related care they receive at a tertiary referral center in Lebanon. METHODS: A retrospective review of charts of 400 patients admitted with a hip fracture to the American University of Beirut-Medical Center, between January 1, 2011 and December 31, 2015. We reviewed medical records of adults admitted with a nonpathologic/nontraumatic hip fracture, and evaluated basic demographics and relevant clinical information, associated risk factors, and the management received. RESULTS: The mean age of the population was 78 ± 10 years and men constituted 37%. Women were more likely to be assessed and/or treated. On admission, 21% were taking calcium and 18% vitamin D supplementation. During hospitalization, vitamin D level was assessed in only 39% of patients; a dietary and an osteoporosis consult were requested on only 32% and 22% of the cases, respectively. One-fourth to a third of patients were discharged on calcium or vitamin D, and less than 5% on bisphosphonates. Bone mineral density was measured in a minority although 21% had a history of previous contralateral hip fracture. One year mortality rate in a subset where follow-up available was 12% in men and 7% in women. CONCLUSION: A large care gap in the management of patients admitted with hip fracture persists despite clear national osteoporosis guidelines. This study provides a strong impetus for establishing and monitoring a fracture liaison service to understand and address barriers to providing optimal care to patients with osteoporosis.

Vitamin D deficiency is common in obese individuals and during weight loss. The recommended vitamin D doses in this specific population are higher than for healthy adults. We reviewed vitamin D supplementation trials in obesity, and during medical or surgical weight loss, and report the effects on 25-hydroxyvitamin D [25(OH)D] concentrations and other relevant outcomes. We conducted a systematic search in PubMed, Medline, Embase and the Cochrane library for relevant randomized controlled trials (RCTs) of oral vitamin D supplementation for at least 3â¯months in obese individuals without weight loss (OB), and those on medical weight loss (MWL) (2010-2018), and following bariatric surgery (Bar S) (without time restriction). Two reviewers screened the identified citations in duplicate and independently and performed full text screening. One reviewer completed data extraction. We identified 13 RCTs in OB, 6 in MWL and 7 in Bar S. Mean baseline 25(OH)D concentrations ranged between 7 and 27â¯ng/ml in OB, 15-29â¯ng/ml in MWL and 15-24â¯ng/ml in Bar S. In OB (Total N 2036 participants), vitamin D doses of 1600-4000â¯IU/d increased mean 25(OH)D concentrations to ≥30â¯ng/ml. Based on three trials during MWL (Total N 359 participants), vitamin D doses of 1200-4600â¯IU/d for 12â¯months increased 25(OH)D concentration to ≥30â¯ng/ml. In Bar S (Total N 615 participants), doses ≥2000â¯IU/d were needed to reach 30â¯ng/ml. The change in 25(OH)D concentration was inversely proportional to the administered dose, and to BMI and baseline level with doses of 600-3000â¯IU/day. With these doses, the change in 25(OH)D concentration [Δ25(OH)D] per 100â¯IU/d was 0.5-1.2â¯ng/ml. Three trials assessed bone mineral density as a primary outcome, but only one of them showed a protective effect of vitamin D against bone loss at all sites post-Bar S. There was no effect of vitamin D on weight loss. Data on extra-skeletal parameters, namely glycemic and vascular indices were mostly identified in OB, and findings were inconsistent. In conclusion, Vitamin D doses ≥1600-2000â¯IU/d may be needed to reach a 25(OH)D concentration of 30â¯ng/ml in obese individuals and following bariatric surgery. The optimal concentration in this population is unknown, and whether the above doses protect against weight loss induced bone loss and fractures still needs to be confirmed. There is no clear evidence for a beneficial effect of vitamin D supplementation on cardio-metabolic parameters in obese individuals, and data on such parameters with weight loss are very scarce. Well-designed long term RCTs assessing the effect of vitamin D supplementation during weight loss on patient important outcomes are needed.

BACKGROUND: Urinary tract infections (UTIs) are among the most common infections in the pediatric population. Over the last two decades, antibiotic resistance is increasing significantly as extended spectrum beta lactamase (ESBL) producing organisms are emerging. The aim of this study is to provide a comprehensive view of the epidemiologic characteristics of UTIs in hospitalized children, examine the risk factors of UTIs caused by ESBL-producing organisms, and determine the resistance patterns in the isolated organisms over the last 10 years. METHODS: Retrospective chart review was conducted at two Lebanese medical centers. Subjects were identified by looking at the following ICD-9 discharge codes: "Urinary tract infection," "UTI," "Cystitis," and/or "Pyelonephritis." Children less than 18 years of age admitted for UTI between January 1st, 2001 and December 31st, 2011 were included. Cases whose urine culture result did not meet our definition for UTI were excluded. Chi-square, Fisher's exact test, and multivariate logistic regression were used to determine risk factors for ESBL. Linear regression analysis was used to determine resistance patterns. RESULTS: The study included 675 cases with a median age of 16 months and female predominance of 77.7% (525 cases). Of the 584 cases caused by Escherichia coli or Klebsiella spp, 91 cases (15.5%) were found to be ESBL-producing organisms. Vesico-ureteral reflux and previous antibiotics use were found to be independent risk factors for ESBL-producing E. coli and Klebsiella spp. (p < 0.05). A significant linear increase in resistance to all generations of Cephalosporins (r (2) = 0.442) and Fluoroquinolones (r (2) = 0.698) was found. CONCLUSION: The recognition of risk factors for infection with ESBL-producing organisms and the observation of increasing overall resistance to antibiotics warrant further studies that might probably lead to new recommendations to guide management of UTIs and antibiotic use in children and adolescents.

INTRODUCTION: Meningococcal disease poses serious health risks globally. The six Neisseria meningitidis serogroups responsible for most of the disease burden are A, B, C, W, X and Y. The case fatality rate remains high worldwide and prevention by vaccination remains the best strategy. Because polysaccharide vaccines are poorly immunogenic in young children, conjugated vaccines were developed to overcome this drawback. The quadrivalent meningococcal conjugate vaccine (MenACWY-TT), comprising the serogroups A, C, W and Y conjugated to tetanus toxoid carrier protein (marketed under the trade name Nimenrix ™), is the first quadrivalent vaccine to be approved in Europe as a single dose for ages 12 months and in Canada for ages 12 months to 55 years. AREAS COVERED: This review addresses the limitations posed by polysaccharide vaccines, compares them with the MenACWY-TT conjugated alternative, and focuses on the clinical studies that investigate the immunogenicity and reactogenicity of MenACWY-TT in various age groups and its co-administration with other vaccines compatible with each age group. EXPERT OPINION: Evidence suggests that MenACWY-TT has a good immunogenicity profile across a broad age range including toddlers, children, adolescents, and adults. It also has an acceptable safety profile and is well tolerated when administered with other vaccines.
