Abstract
Despite the fact that mosquito-borne infections have considerable consequences for public health in Saudi Arabia, there is neither a thorough review of the species that occur in the country nor updated keys for the identification of the adult females. In this study, species accounts are given for 49 Saudi Arabian mosquito species, as well as Aedes albopictus (Skuse), which is not recorded in Saudi Arabia, but is medically important and is found in some countries of the Middle East and North Africa. Taxonomic notes provide additional information for certain taxa and/or aid their identification.

Abstract
OBJECTIVE Incidence of ulcerative colitis is globally increased. Enteric infections and their role in ulcerative colitis flares present a common health problem and a unique clinical challenge. We aimed to identify enteropathogens in flared ulcerative colitis patients and their antimicrobial susceptibilities and relation with the disease activity. METHODS Stool samples were collected from 95 patients with ulcerative colitis (17 inactive cases and 78 active cases) according to the Mayo score assessment of ulcerative colitis severity. Enteropathogens were examined using an automated VITEK2 system and FilmArray gastrointestinal pathogen panel. RESULTS Enteric infections were found in 81 patients (85.3%) with a significantly higher percentage in active ulcerative colitis (96.2% vs. 35.3%, P < 0.001). In 78 symptomatic patients, (78.7%) of bacteria as enteroaggregative and enteropathogenic E. coli , (11.5%) parasitic as Cryptosporidium and (7.7%) viral as Norovirus were the most detected microbial pathogens. Mixed, multidrug-resistant organisms (MDROs) and opportunistic infections were reported in 70.7%, 52.9% and 46.7% respectively. Raoultella ornithinolytica was reported for the first time as an enteropathogen in ulcerative colitis flare. Multiple organisms, MDROs, extended-spectrum beta-lactamases-producing and AmpC-resistant bacteria were significantly associated with disease severity. CONCLUSION Identifying enteropathogens especially opportunistic and MDR organisms as a cause of ulcerative colitis flare-ups is a matter of worry increasing their diagnostic and therapeutic burden. Periodic studies evaluating changes in microbial profiles and their antimicrobial susceptibilities are needed to achieve antibiotic stewardship and improve management.

Abstract
Introduction Carbapenem-resistant Enterobacteriaceae (CRE) infections resist nearly most available antimicrobials, resulting in poor clinical outcomes. Saudi Arabia has a relatively high CRE prevalence. This study aims to evaluate the sensitivity of Rapidec Carba NP test and GeneXpert Carba-R assay compared with conventional manners for detection of carbapenemase-producing Enterobacteriaceae. Methods This is a cross-sectional study including a total of 90 CRE isolates examined at two tertiary hospitals in KSA from October 2020 to December 2021. Gram-negative Enterobacteriaceae were identified by using Vitek 2 system and were furtherly tested for imipenem and meropenem susceptibility by E- test strips, followed by Rapidec Carba NP test and the Xpert™Carba-R assay. Results Carbapenem-resistant K. pneumoniae (78.9%) and carbapenem-resistant E. coli (14.4%) were the two most common isolates species. Colistin (98.9%) and tigecycline (88.9%) were the most effective antibiotics against CRE isolates, followed by amikacin (52.2%), gentamicin (33.3%), cotrimoxazole (15.6%), and ciprofloxacin (8.9%). blaOXA-48 was the predominant carbapenemase gene (44.4%), followed by blaNDM (32.2%). blaKPC gene was not detected. The Rapidec Carba NP and the Xpert™Carba-R demonstrated an overall sensitivity of 69.3% and 88%, respectively, in comparison to gold standard detection of meropenem and imipenem resistance by Vitek 2 system and E- test strips. Discussion RAPIDEC® CARBA NP may be a beneficial screening test for detecting CRE, but for confirmation of the results, Xpert Carba-R assay is more sensitive, significantly lowering the turnaround time compared to reference traditional methods. The information on carbapenemase genes may be used for epidemiologic purposes and outbreak management.

Abstract
Healthcare-associated infections lead to considerable morbidity, a prolonged hospital stay, antibiotic resistance, long-term disability, mortality and increased healthcare costs. Based on the literature, some individual and socio-demographic factors including knowledge, age and length of service or work experience, gender and type of profession influence compliance with infection prevention and control procedures. In addition, organizational culture, which refers to the assumptions, values, and norms shared among colleagues, can influence an individual's thinking and healthcare workers' behavior, either positively or negatively. Infection control practices based on the perspective of patients, hospital management and healthcare workers may help develop a better understanding of the factors influencing compliance with infection prevention and control policies and guidelines.

Abstract
Background and Objective: Despite that inherited (thalassemia and SCA) and infectious (hepatitis B, hepatitis C and AIDs) diseases and their risk factor consanguineous marriage are widespread among Yemen population, community-based awareness studies towards premarital screening (PMS) is extremely limited, so our study is designed to elicit knowledge and attitude of engaged and recently married couples in Taiz (Yemen) toward PMS. Methods: A cross-sectional study was conducted from April to September 2021 at Taiz. A well-structured questionnaire was designed and then delivered to participants to collect data. Results: The results revealed that majority of respondents (83.60%-94.18%) had knowledge about inherited and infectious diseases, respectively, and educational institution was the main knowledge source. Females had significantly higher knowledge than males (P ≤ .01), except about AIDs since no difference (P = .539). The results also revealed that majority of respondents had positive attitudes toward PMS, except toward AIDs testing since 70% of males and 68.91% of females had negative attitudes. The majority of respondents agreed that screening reduces the diseases incidence. Approximately half of respondents (50.79%-56.61%) tend to go ahead for marriage in case of positive results for inherited and infectious diseases respectively. Making PMS as an obligatory step prior engagement was agreed by 47.62% of respondents (45.71% of males, 48.74% of females). Conclusion: A high level of knowledge and positive attitudes toward inherited and infectious diseases and PMS were reported. This knowledge reflected on the agreement of majority of respondents regarding PMS importance in term of reduction of diseases incidence.

Abstract
Malaria is the most common vector-borne parasitic infection causing significant human morbidity and mortality in nearly 90 tropical/sub-tropical countries worldwide. Significant differences exist in the incidence of malaria cases, dominant Plasmodium species, drug-resistant strains and mortality rates in different countries. Six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Qatar, Oman, Saudi Arabia and United Arab Emirates, UAE) in the Middle East region with similar climates, population demographics and economic prosperity are aiming to achieve malaria elimination. In this narrative review, all studies indexed in PubMed describing epidemiological characteristics of indigenous and imported malaria cases, vector control status and how malaria infections can be controlled to achieve malaria elimination in GCC countries were reviewed and discussed. These studies have shown that indigenous malaria cases are absent in Bahrain, Kuwait, Qatar and UAE and have progressively declined in Oman and Saudi Arabia. However, imported malaria cases continue to occur as GCC countries have large expatriate populations originating from malaria-endemic countries. Various malaria control and prevention strategies adopted by GCC countries including more stringent measures to reduce the likelihood of importing malaria cases by prior screening of newly arriving expatriates and vector elimination programs are likely to lead to malaria elimination in this region.

Abstract
Vector-borne parasitic infectious diseases are important causes of morbidity and mortality globally. Malaria is one of the most common vector-borne parasitic infection and is caused by five Plasmodium species, namely P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi. Epidemiologically, differences in the patterns of malaria cases, causative agent, disease severity, antimicrobial resistance, and mortality exist across diverse geographical regions. The world witnessed 229 million malaria cases which resulted in 409,000 deaths in 2019 alone. Although malaria cases are reported from 87 countries globally, Africa bears the brunt of these infections and deaths as nearly 94% of total malaria cases and deaths occur in this continent, particularly in sub-Saharan Africa. Most of the Middle East Region countries are malaria-free as no indigenous cases of infection have been described in recent years. However, imported cases of malaria continue to occur as some of these countries. Indeed, the six Gulf Cooperation Council (GCC) countries have large expatriate population originating from malaria endemic countries. In this review, the current status and epidemiology of malaria in the Middle East Region countries and other malaria-endemic countries that are home to a large migrant workforce being employed in Middle East Region countries are discussed.

Abstract
Objectives Little is known about the prevalence of febrile illness in the Arabian region as clinical, laboratory and immunological profiling remains largely uncharacterised. Methods A total of 2018 febrile patients from Jazan, Saudi Arabia, were recruited between 2014 and 2017. Patients were screened for dengue and chikungunya virus, Plasmodium, Brucella, Neisseria meningitidis, group A streptococcus and Leptospira. Clinical history and biochemical parameters from blood tests were collected. Patient sera of selected disease-confirmed infections were quantified for immune mediators by multiplex microbead-based immunoassays. Results Approximately 20% of febrile patients were tested positive for one of the pathogens, and they presented overlapping clinical and laboratory parameters. Nonetheless, eight disease-specific immune mediators were identified as potential biomarkers for dengue (MIP-1α, MCP-1), malaria (TNF-α), streptococcal and meningococcal (eotaxin, GRO-α, RANTES, SDF-1α and PIGF-1) infections, with high specificity and sensitivity profiles. Notably, based on the conditional inference model, six of these mediators (MIP-1α, TNF-α, GRO-α, RANTES, SDF-1α and PIGF-1) were revealed to be 68.4% accurate in diagnosing different febrile infections, including those of unknown diseases. Conclusions This study is the first extensive characterisation of the clinical analysis and immune biomarkers of several clinically important febrile infections in Saudi Arabia. Importantly, an immune signature with robust accuracy, specificity and sensitivity in differentiating several febrile infections was identified, providing useful insights into patient disease management in the Arabian Peninsula.

Ten-year resistance trends in pathogens causing healthcare-associated infections; reflection of infection control interventions at a multi-hospital healthcare system in Saudi Arabia, 2007-2016. Antimicrob Resist Infect Control 2020; 9:21.

Abstract
Background Studying temporal changes in resistant pathogens causing healthcare-associated infections (HAIs) is crucial in improving local antimicrobial and infection control practices. The objective was to describe ten-year trends of resistance in pathogens causing HAIs in a tertiary care setting in Saudi Arabia and to compare such trends with those of US National Health Surveillance Network (NHSN). Methods Pooled analysis of surveillance data that were prospectively collected between 2007 and 2016 in four hospitals of Ministry of National Guard Health Affairs. Definitions and methodology of HAIs and antimicrobial resistance were based on NHSN. Consecutive NHSN reports were used for comparisons. Results A total 1544 pathogens causing 1531 HAI events were included. Gram negative pathogens (GNP) were responsible for 63% of HAIs, with a significant increasing trend in Klebsiella spp. and a decreasing trend in Acinetobacter. Methicillin-resistant Staphylococcus aureus (27.0%) was consistently less frequent than NHSN. Vancomycin-resistant Enterococci (VRE, 20.3%) were more than doubled during the study, closing the gap with NHSN. Carbapenem resistance was highest with Acinetobacter (68.3%) and Pseudomonas (36.8%). Increasing trends of carbapenem resistance were highest in Pseudomonas and Enterobacteriaceae, closing initial gaps with NHSN. With the exception of Klebsiella and Enterobacter, multidrug-resistant (MDR) GNPs were generally decreasing, mainly due to the decreasing resistance towards cephalosporins, fluoroquinolones, and aminoglycosides. Conclusion The findings showed increasing trends of carbapenem resistance and VRE, which may reflect heavy use of carbapenems and vancomycin. These findings may highlight the need for effective antimicrobial stewardship programs, including monitoring and feedback on antimicrobial use and resistance.

Abstract
Tuberculosis (TB) represents a significant challenge to public health authorities, especially with the emergence of drug-resistant (DR) and multidrug-resistant (MDR) isolates of Mycobacterium tuberculosis. We sought to examine the genomic variations among recently isolated strains of M. tuberculosis in two closely related countries with different population demography in the Middle East. Clinical isolates of M. tuberculosis from both Egypt and Saudi Arabia were subjected to phenotypic and genotypic analysis on gene and genome-wide levels. Isolates with MDR phenotypes were highly prevalent in Egypt (up to 35%) despite its relatively stable population structure (sympatric pattern). MDR-TB isolates were not identified in the isolates from Saudi Arabia despite its active guest worker program (allopatric pattern). However, tuberculosis isolates from Saudi Arabia, where lineage 4 was more prevalent (>65%), showed more diversity than isolates from Egypt, where lineage 3 was the most prevalent (>75%). Phylogenetic and molecular dating analyses indicated that lineages from Egypt were recently diverged (~78 years), whereas those from Saudi Arabia were diverged by over 200 years. Interestingly, DR isolates did not appear to cluster together or spread more widely than drug-sensitive isolates, suggesting poor treatment as the main cause for emergence of drug resistance rather than more virulence or more capacity to persist.

Abstract
Dissemination of carbapenemase-producing Klebsiella pneumoniae along with 16S rRNA methyltransferase (16S-RMTase) has been caused as a great concern for healthcare settings. The aim of this study was to investigate the prevalence of resistance genes among K. pneumoniae isolates. During October 2015 to February 2016, 30 non-duplicative K. pneumoniae strains were isolated from clinical specimens in a burn center in Kerman, Iran. Antibiotic susceptibility tests of isolates, carbapenemase, extended-spectrum beta-lactamases (ESBLs) and AmpC beta-lactamase-producing isolates were determined by phenotypic methods. The beta-lactamase, oqxA/B efflux pumps, qnr A, B, S, 16S-RMTase (rmt A, B, and C), and mcr-1 resistance genes were determined by PCR. Enterobacterial repetitive intergenic consensus (ERIC)-PCR was used for molecular typing. According to our findings, tigecycline has been shown the most active agent against K. pneumoniae isolates. Antibiotic resistance genes, blaTEM-1, blaSHV-12, blaCTX-M-15, blaCTX-M-2, blaNDM-1, blaFOX, blaMOX, blaEBC, blaACC, blaCIT, rmtC, qnrB, qnrS, oqxA, and oqxB, were detected in 11 (36.7%), 13 (43.3%), 11 (36.6%), 5 (16.6%), 9 (30%), 1 (3.3%), 1 (3.3%), 1 (3.3%), 1 (3.3%), 2 (6.7%), 1 (3.3%), 9 (30%), 2 (6.7%), 18 (60%), and 13 (43.3%) of isolates, respectively. The blaNDM-1 with rmtC was simultaneously observed in one isolate. ERIC-PCR results revealed 25 distinct patterns in eight clusters (A-H) and five singletons. This study highlights the high prevalence of blaNDM and emergence of rmtC among carbapenem-resistant K. pneumoniae. The resistance genes are often co-located on the conjugative plasmids, so it might be the reason of the rapid spread of them. The prevalence of multidrug-resistant K. pneumoniae isolates limits the available treatment options and presents tremendous challenges to public health.

Ticks and Tick-Borne Infections: Complex Ecology, Agents, and Host Interactions. Vet Sci 2018; 5:vetsci5020060. [PMID: 29925800 PMCID: PMC6024845 DOI: 10.3390/vetsci5020060] [Citation(s) in RCA: 90] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Revised: 06/11/2018] [Accepted: 06/15/2018] [Indexed: 12/21/2022] Open
Abstract
Ticks transmit the most diverse array of infectious agents of any arthropod vector. Both ticks and the microbes they transmit are recognized as significant threats to human and veterinary public health. This article examines the potential impacts of climate change on the distribution of ticks and the infections they transmit; the emergence of novel tick-borne pathogens, increasing geographic range and incidence of tick-borne infections; and advances in the characterization of tick saliva mediated modulation of host defenses and the implications of those interactions for transmission, establishment, and control of tick infestation and tick-borne infectious agents.

Abstract
Objectives To evaluate the knowledge and attitudes of dental students at Jazan University, Saudi Arabia; compare the differences in HIV/AIDS related knowledge and attitudes between the genders and years of study. Methods This cross-sectional survey was conducted among dental students of Jazan University (N = 208; Response rate = 88.1%). Results Most of the students (93%) knew “HIV/AIDS patients can infect dental workers” and 14% were unaware of the fact that HIV/AIDS patients can be diagnosed with oral manifestations. Less than half the subjects (47.6%) were confident on their ability to safely treat HIV/AIDS patients and only 28.8% of the study population believed that their knowledge about infection control is enough to treat HIV/AIDS patients. Males and 4th year students had significantly greater HIV/AIDS related knowledge and attitudes than their comparative counterparts. Conclusions HIV/AIDS related knowledge and attitudes in dental students of Jazan University are comparable to other studies from Saudi but are poor when compared to other countries.

Abstract
Viral hemorrhagic fever (VHF) refers to a group of diseases characterized by an acute febrile syndrome with hemorrhagic manifestations and high mortality rates caused by several families of viruses that affect humans and animals. These diseases are typically endemic in certain geographical regions and sometimes cause major outbreaks. The history of hemorrhagic fever in the Arabian Peninsula refers to the 19th century and most outbreaks were reported in the Tihamah region—the Red Sea coastal plain of the Arabian Peninsula in the west and southwest of Saudi Arabia and Yemen. Herein, we describe the agents that cause VHFs and their epidemiology in Tihamah, the history of the diseases, transmission, species affected, and clinical signs. Finally, we address challenges in the diagnosis and control of VHFs in this region.

Abstract
BACKGROUND Management of patients with drug-resistant tuberculosis is highly complicated because of the longer treatment time, lesser effectiveness of second-line antituberculosis drugs, more side-effects, and a significant financial burden on tuberculosis control programs. This study aimed to identify predictors of drug-resistant tuberculosis. MATERIALS AND METHODS It was a case-control record study conducted in an antituberculosis center in a government hospital in the Eastern Province of Saudi Arabia. Cases were pulmonary tuberculosis patients with antituberculosis drug resistance (n=80), and controls were pulmonary tuberculosis patients without drug resistance (n=101). Data were collected from patients' records during the period from January 2008 to February 2013. RESULTS Male sex [odds ratio (OR)=5.764; 95% confidence interval (CI) 2.024-16.421], smoking (OR=4.605; 95% CI 1.864-11.378), and positive Acid Fast Bacilli smear on admission (OR=40.149; 95% CI 9.010-178.914) were the risk factors for developing drug resistance (P<0.05 for each) in the sample. CONCLUSION AND RECOMMENDATIONS Positive AFB smear on admission, male sex, and smoking are risk factors for developing drug-resistant TB. These predictors should be used to formulate a health policy to monitor tuberculosis patients so as to prevent drug resistance.

Abstract
Despite major advances in basic and applied research and the availability of several vaccines, viral diseases still account for a large proportion of the human infectious disease burden. Many viruses cause self-limiting and relatively mild infections, but several, including human immunodeficiency virus and influenza virus, are responsible for millions of deaths every year throughout the world. Several factors contribute to the enormous impact that viruses have on human health. For example, there are very few therapeutic options available for the treatment of viral infections, and many of those that are available possess a limited spectrum of activity or are designed for the treatment of diseases caused by specific viruses (e.g., oseltamivir is intended for the treatment of influenza only). In addition, the rapid evolution of viruses has led to the emergence of drug-resistant strains against which no currently available therapeutics are effective. Coupled with these and other issues are the appearance of never before seen viruses and the emergence of known but previously underappreciated viruses. Since the beginning of the twenty-first century, numerous “new” viruses, including the coronaviruses responsible for severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), the 2009 pandemic influenza A virus, and Lujo hemorrhagic fever virus, have made their debut and have proved to be formidable threats to human health. Recently, the appearance of Ebola virus (Zaire ebolavirus) in West Africa, a region that has not previously seen an outbreak of this virus, was marked by an epidemic that afflicted nearly 30,000 individuals and killed more than 11,000 of those who were infected. Most recently, the far-reaching and rapid spread of Zika virus, a mosquito-borne virus that was discovered in the 1940s in Uganda, in the Western Hemisphere has invoked considerable public and scientific attention and has given rise to perhaps the largest concerted effort by scientists to rapidly develop a vaccine to halt the transmission of a virus. Each of these points underscores the importance of further research into improved surveillance, diagnosis, treatment, and prevention of viral diseases.

[PMID: 27621823 PMCID: PMC5009225 DOI: 10.1016/j.nmni.2016.07.009] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2016] [Revised: 07/13/2016] [Accepted: 07/25/2016] [Indexed: 12/13/2022] Open
Abstract
Changes in the molecular epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) continue to be reported. This study was carried out to characterize MRSA isolates in Saudi Arabia. MRSA isolates causing nosocomial infections (n = 117) obtained from 2009–2015 at a tertiary-care facility in Riyadh, Saudi Arabia, were studied. Molecular characterization of isolates was carried out using the StaphyType DNA microarray (Alere Technologies, Jena, Germany). Fourteen clonal complexes (CC) were identified, with the most common being CC80 (n = 35), CC6 (n = 15), CC5 (n = 13) and CC22 (n = 12). With the exception of nine ST239 MRSA-III isolates, all others were of community-associated MRSA lineages. The following strains are identified for the first time in Saudi Arabia: ST8-MRSA-IV [PVL+/ACME+], USA300 (n = 1); ST72-MRSA-IV USA700 (n = 1); CC5-MRSA-IV, [PVL+/edinA+], WA MRSA-121 (n = 1); CC5-MRSA-V+SCCfus, WA MRSA-14/109 (n = 2), CC97-MRSA-IV, WA MRSA-54/63; CC2250/2277-MRSA-IV and WA MRSA-114. CC15-MRSA (n = 3) was identified for the first time in clinical infection in Saudi Arabia. None of the isolates harboured vancomycin resistance genes, while genes for resistance to mupirocin and quaternary ammonium compounds were found in one and nine isolates respectively. Fifty-seven isolates (48.7%) were positive for Panton-Valentine leukocidin genes. While the staphylokinase (sak) and staphylococcal complement inhibitor (scn) genes were present in over 95% of the isolates, only 37.6% had the chemotaxis-inhibiting protein (chp) gene. Increasing occurrence of community-acquired MRSA lineages plus emergence of pandemic and rare MRSA strains is occurring in our setting. Strict infection control practices are important to limit the dissemination of these MRSA strains.

Abstract
BACKGROUND The Hajj is the largest annual mass gathering event in the world, thus favoring the transmission of various infections: 183 different nationalities, high temperatures, coincidence with the start of the flu season in the Northern hemisphere, a long barefoot walk, tent-type accommodation, communal toilet facilities, absence of food control, and sharing of razors. Infections are the first cause of hospital admission, which often occurs in the home country of pilgrims. METHODS Literature review on PubMed from 1952 to November 2015 on the epidemiology and prevention of infections contracted during the Hajj, using the keywords "Hajj" and "infections". RESULTS Respiratory tract infections, ENT infections, influenza, pyogenic pneumonia, whooping cough, and tuberculosis are most frequently observed during the Hajj. Outbreaks of meningococcal meningitis have been reported in pilgrims and their contacts. Waterborne infections such as gastroenteritis and hepatitis A are common, despite the improvement of health conditions. Pyoderma and furuncles are also frequently observed. Recently, dengue fever, Alkhumra hemorrhagic fever, and Rift Valley fever have emerged but no case of MERS-coronavirus, appeared in Saudi Arabia in 2012, have yet been observed during the 2012-2014 Hajj. CONCLUSION Prevention is based on compulsory meningococcal vaccination, vaccination against seasonal influenza and pneumococcal infections for pilgrims at high risk of contracting the infection, and on vaccination against hepatitis A. Updating immunization for diphtheria/tetanus/poliomyelitis/pertussis and measles/mumps is also crucial and pilgrims must comply with hygiene precautions.

Abstract
Streptococcus pneumoniae (pneumococcus) is the leading cause of morbidity and mortality worldwide. Saudi Arabia is a host to millions of pilgrims who travel annually from all over the world for Umrah and the Hajj pilgrimages and are at risk of developing pneumococcal pneumonia or invasive pneumococcal disease (IPD). There is also the risk of transmission of S. pneumoniae including antibiotic resistant strains between pilgrims and their potential global spread upon their return. The country also has unique challenges posed by susceptible population to IPD due to people with hemoglobinopathies, younger age groups with chronic conditions, and growing problem of antibiotic resistance. Since the epidemiology of pneumococcal disease is constantly changing, with an increase in nonvaccine pneumococcal serotypes, vaccination policies on the effectiveness and usefulness of vaccines require regular revision. As part of the Saudi Thoracic Society (STS) commitment to promote the best practices in the field of respiratory diseases, we conducted a review of S. pneumoniae infections and the best evidence base available in the literature. The aim of the present study is to develop the STS pneumococcal vaccination guidelines for healthcare workers in Saudi Arabia. We recommend vaccination against pneumococcal infections for all children <5 years old, adults ≥50 years old, and people ≥6 years old with certain risk factors. These recommendations are based on the presence of a large number of comorbidities in Saudi Arabia population <50 years of age, many of whom have risk factors for contracting pneumococcal infections. A section for pneumococcal vaccination before the Umrah and Hajj pilgrimages is included as well.

Abstract
BACKGROUND Although a vaccine could be available as early as 2016, vector control remains the primary approach used to prevent dengue, the most common and widespread arbovirus of humans worldwide. We reviewed the evidence for effectiveness of vector control methods in reducing its transmission. METHODOLOGY/PRINCIPAL FINDINGS Studies of any design published since 1980 were included if they evaluated method(s) targeting Aedes aegypti or Ae. albopictus for at least 3 months. Primary outcome was dengue incidence. Following Cochrane and PRISMA Group guidelines, database searches yielded 960 reports, and 41 were eligible for inclusion, with 19 providing data for meta-analysis. Study duration ranged from 5 months to 10 years. Studies evaluating multiple tools/approaches (23 records) were more common than single methods, while environmental management was the most common method (19 studies). Only 9/41 reports were randomized controlled trials (RCTs). Two out of 19 studies evaluating dengue incidence were RCTs, and neither reported any statistically significant impact. No RCTs evaluated effectiveness of insecticide space-spraying (fogging) against dengue. Based on meta-analyses, house screening significantly reduced dengue risk, OR 0.22 (95% CI 0.05-0.93, p = 0.04), as did combining community-based environmental management and water container covers, OR 0.22 (95% CI 0.15-0.32, p<0.0001). Indoor residual spraying (IRS) did not impact significantly on infection risk (OR 0.67; 95% CI 0.22-2.11; p = 0.50). Skin repellents, insecticide-treated bed nets or traps had no effect (p>0.5), but insecticide aerosols (OR 2.03; 95% CI 1.44-2.86) and mosquito coils (OR 1.44; 95% CI 1.09-1.91) were associated with higher dengue risk (p = 0.01). Although 23/41 studies examined the impact of insecticide-based tools, only 9 evaluated the insecticide susceptibility status of the target vector population during the study. CONCLUSIONS/SIGNIFICANCE This review and meta-analysis demonstrate the remarkable paucity of reliable evidence for the effectiveness of any dengue vector control method. Standardised studies of higher quality to evaluate and compare methods must be prioritised to optimise cost-effective dengue prevention.

Abstract
Methicillin-resistant Staphylococcus Aureus (MRSA) infections in hospital have obviously imposed a significant burden of morbidity and mortality, and strain on healthcare resources. Here, we review the genotype distribution of these pathogens in the Kingdom of Saudi Arabia (KSA). A PubMed literature search (until May 2014) specified 12 articles that characterized MRSA clones in KSA. Only two regions (Riyadh and Damamm) were represented in ten articles. Data from these articles showed that the pandemic Vienna/Hungarian/Brazilian clone (CC8/ST239-III) is the most frequent in Saudi regions (Riyadh and Damamm). Several other clones such as Barnim/UK-EMRSA-15 (CC22-IV), Southwest Pacific clone (ST30-IV) and European community-associated-MRSA clone (CC80-IV) have been detected in the Riyadh region. A variety of MRSA clones is beginning to circulate in Saudi hospitals. Continued collection and molecular characterization of MRSA is crucial for the effective prevention and treatment.

Abstract
Alkhumra virus (ALKV) is an emerging tick-borne flavivirus known to cause a neglected tropical disease in the Middle East. The magnitude of the disease among European returning travelers is still unknown probably because the inadequate knowledge about the real geographic distribution of ALKV infection have limited its diagnosis. Up to now in Italy were reported only three cases; here we report the fourth case of ALKV in a returning traveler from south Egypt.

Abstract
BACKGROUND To meet the future challenges of infectious diseases and limit the spread of multidrug resistant microorganisms, a better understanding of published studies in the field of infectious diseases is needed. The objective of this study was to analyze the quantity and quality of research activity in the field of infectious diseases in Arab countries and compare it with that in non-Arab countries. METHODS Documents published in Arab countries within the research category of "infectious diseases" were extracted and analyzed using the Web of Science database. The data analyzed represent research productivity during the time interval between 1900 - 2012. RESULTS Worldwide, the total number of documents published in the field of infectious diseases up to 2012 was 227,188. A total of 2,408 documents in the field of infectious diseases were published in Arab countries, which represents 1.06% of worldwide research output. Research output from Arab countries in the field of infectious diseases was low for decades. However, approximately a five-fold increase was observed in the past decade. Arab countries ranked 56(th) to 218(th) on the standard competition ranking (SCR) in worldwide publications in the field of infectious diseases. Egypt, with a total publication of 464 (19.27%) documents ranked first among Arab countries, while Kuwait University was the most productive institution with a total of 158 (6.56%) documents. Average citation per document published in Arab countries was 13.25 and the h-index was 64. Tuberculosis (230; 9.55%), malaria (223; 9.26%), and hepatitis (189; 7.8%) were the top three infectious diseases studied as according to the retrieved documents. CONCLUSION The present data reveals that some Arab countries contribute significantly to the field of infectious diseases. However, Arab countries need to work harder to bridge the gap in this field. Compared with non-Arab countries in the Middle East, research output from Arab countries was high, but more efforts are needed to enhance the quality of this output. Future research in the field should be encouraged and correctly directed.

Abstract
Religious festivals attract a large number of pilgrims from worldwide and are a potential risk for the transmission of infectious diseases between pilgrims, and to the indigenous population. The gathering of a large number of pilgrims could compromise the health system of the host country. The threat to global health security posed by infectious diseases with epidemic potential shows the importance of advanced planning of public health surveillance and response at these religious events. Saudi Arabia has extensive experience of providing health care at mass gatherings acquired through decades of managing millions of pilgrims at the Hajj. In this report, we describe the extensive public health planning, surveillance systems used to monitor public health risks, and health services provided and accessed during Hajj 2012 and Hajj 2013 that together attracted more than 5 million pilgrims from 184 countries. We also describe the recent establishment of the Global Center for Mass Gathering Medicine, a Saudi Government partnership with the WHO Collaborating Centre for Mass Gatherings Medicine, Gulf Co-operation Council states, UK universities, and public health institutions globally.

Surveillance, control and management of infections in intensive care units in Southern Europe, Turkey and Iran--a prospective multicenter point prevalence study. J Infect 2013; 68:131-40. [PMID: 24269951 DOI: 10.1016/j.jinf.2013.11.001] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2013] [Revised: 10/01/2013] [Accepted: 11/01/2013] [Indexed: 12/29/2022]
Abstract
OBJECTIVE We aimed to compare the features of intensive care units (ICUs), their antimicrobial resistance patterns, infection control policies, and distribution of infectious diseases from central Europe to Mid-West Asia. METHODS A cross-sectional point prevalence study was performed in 88 ICUs from 12 countries. Characteristics of ICUs, patient and antibiotic therapy data were collected with a standard form by infectious diseases specialists. RESULTS Out of 749, 305 patients at least with one infectious disease were assessed and 254 patients were reported to have coexistent medical problems. When primary infectious diseases diagnoses of the patients were evaluated, 69 had community-acquired, 61 had healthcare-associated, and 176 had hospital-acquired infections. Pneumonia was the most frequent ICU infection seen in half of the patients. Distribution of frequent pathogens was as follows: Enteric Gram-negatives (n = 62, 28.8%), Acinetobacter spp. (n = 47, 21.9%), Pseudomonas aeruginosa (n = 29, 13.5%). Multidrug resistance profiles of the infecting microorganisms seem to have a uniform pattern throughout Southern Europe and Turkey. On the other hand, active and device-associated infection surveillance was performed in Turkey more than Iran and Southeastern Europe (p < 0.05). However, designing antibiotic treatment according to culture results was highest in Southeastern Europe (p < 0.05). The most frequently used antibiotics were carbapenems (n = 92, 30.2%), followed by anti-gram positive agents (vancomycin, teicoplanin, linezolid, daptomycin, and tigecycline; n = 79, 25.9%), beta-lactam/beta lactamase inhibitors (n = 78, 25.6%), and extended-spectrum cephalosporins (n = 73, 23.9%). CONCLUSION ICU features appears to have similar characteristics from the infectious diseases perspective, although variability seems to exist in this large geographical area.

[PMID: 24021566 DOI: 10.1016/j.ijid.2013.06.016] [Citation(s) in RCA: 83] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Revised: 06/16/2013] [Accepted: 06/16/2013] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVES To investigate the emergence of NDM-, OXA-48-, and VIM-producing Klebsiella pneumoniae in Saudi Arabia. METHODS From June to December 2011, we obtained K. pneumoniae isolates with reduced sensitivity to carbapenem identified in Riyadh, Saudi Arabia. Only non-duplicate clinical and surveillance isolates obtained from inpatients were included. PCR amplification was carried out for the detection of extended-spectrum beta-lactamase genes (blaCTX-M, blaTEM, blaSHV) and carbapenemase genes (blaKPC, blaVIM, blaIMP, blaNDM, and blaOXA-48). Susceptibility to imipenem, meropenem, amikacin, gentamicin, trimethoprim-sulfamethoxazole, and colistin was determined. RESULTS Of the 60K. pneumoniae isolates studied, 45 were from patients in the intensive care unit. Forty-seven isolates harbored blaOXA-48, 12 were positive for blaNDM, and one for blaVIM. No isolate harbored a combination of these resistance genes. No isolate harbored blaKPC or blaIMP. All 37 blaCTX-M-positive isolates belonged to CTX-M group 1, and 29 were positive for a combination of blaCTX-M and blaOXA-48. blaTEM and blaSHV genes were found in 17 and 39 isolates, respectively. All isolates were imipenem- and meropenem-resistant, with a high rate of co-resistance to the other antibiotics. Three blaOXA-48-positive isolates with colistin resistance were detected. CONCLUSION Multidrug-resistant K. pneumoniae isolates harboring blaOXA-48, blaNDM, and colistin resistance are emerging in Saudi Arabia.
