General public knowledge,perceptions and practice towards pharmaceutical drug advertisements in the Western region of KSA

This study aims to examine general public knowledge and behavior toward pharmaceutical advertisements in the Western part of KSA. A cross sectional convenience sampling technique was used in this study. A total of 1445 valid questionnaires were received and analyzed using SPSS version 16 at alpha value of 0.05. Majority of respondents were aware of different types of drugs to be advertised and drug advertisements should seek approval from the health authorities. Television and Internet showed the highest effect on consumers. Almost half of the participants preferred an advertised drug over non-advertised one. Most of the respondents indicated that the quality of frequently advertised drugs is not better than those prescribed by the doctors. Majority of participants had positive beliefs toward advertised drugs concerning their role in education and spreading of awareness among the public. Pharmaceutical advertisements harm the doctor–patient relationship as evidenced by one-third of the investigated sample. Moreover, majority of the participants mentioned that they would consult another doctor or even change the current doctor if he/she refused to prescribe an advertised medication. Results of this study could be used to develop awareness programs for the general public and try to enforce the regulations and policies to protect the general public and patients from the business oriented pharmaceutical companies and drug suppliers.     

Long-term compliance with bladder management in patients with spinal cord injury: A Saudi-Arabian perspective

Objective: To examine long-term compliance with bladder management in patients with spinal cord injury (SCI) at a tertiary care rehabilitation facility in Saudi Arabia.

Design: Cross-sectional survey.

Setting: Tertiary care rehabilitation facility in Saudi Arabia.

Participants: A self-administered questionnaire was distributed to patients with SCI during their clinic visits. 50 patients (41 males and nine females) participated in the survey. Data documentation included demographic characteristics, type and level of injury, compliance with bladder management and barriers in compliance.

Main outcome measures: The type of bladder management employed at first follow-up visit was compared with that employed at discharge.

Results: Eleven out of 41 patients who were discharged on clean intermittent catheterization (CIC) stopped it within 3 months of discharge, mainly due to lack of accessibility and financial support to buy catheters. Of the total sample, 23% reported that they did not know the difference between catheter types and their advantages, and 49% stated that they did not receive proper health education regarding bladder management.

Conclusion: CIC was the most commonly used bladder management technique in patients with SCI following up at a tertiary care rehabilitation facility in Saudi Arabia. Compliance with CIC may be improved by ensuring access to catheters post-discharge and by providing appropriate education about bladder management during inpatient rehabilitation.     

Molecular characterization of fowl aviadenoviruses species D and E associated with inclusion body hepatitis in chickens and falcons indicates possible cross-species transmission

During the period from 2015 to 2017, frequent outbreaks of inclusion body hepatitis (IBH) were observed in broiler chickens and falcons in Saudi Arabia. Fifty samples were collected from both species. The histopathological examination and polymerase chain reaction confirmed the IBH infection in eight samples (five samples from chickens and three samples from falcons). The genomic sequence and phylogenetic analysis based on nucleotide and amino acid sequences of Saudi strains, reference fowl aviadenoviruses (FAdVs) and field viruses available in Genbank revealed that all investigated FAdVs clustered into FAdV-2 (species D) and FAdV-6 (species E). The host-dependent characterization revealed that falcon origin strains showed low identity (～35%) with falcon adenoviruses isolated from USA, which clustered into a separate group. The identification of FAdV-D and FAdV-E in diseased falcons and chickens indicates cross-species transmission although falcons and chickens are phylogenetically different. The control of IBH infection in falcons and chickens should be based on the separation of carriers and susceptible chickens as well as falcons to prevent cross-species contact. Vaccination is an important method for prevention of IBH. The characterization of newly emerging FAdV strains provides valuable information for the development of an efficacious control strategy based on the molecular structure of current circulating FAdV strains in different species of birds.     

Psychometric analysis of the Arabic (Saudi) Tilburg Frailty Indicator among Saudi community-dwelling older adults

BackgroundFrailty is a common geriatric syndrome that can be screened using validated questionnaires. A commonly used assessment is the Tilburg Frailty Indicator (TFI), containing fifteen self-reported questions about components of frailty, with scores ranging from zero to fifteen (higher scores representing increased frailty and a cutoff score of greater than five used to diagnose frailty). Despite its widespread use, the TFI is not commonly used in Arabic-speaking countries, and there is an overall lack of Arabic-translated questionnaires to adequately detect and measure frailty for older adults in Saudi Arabia.ObjectivesTo translate and cross-culturally adapt the Tilburg Frailty Indicator (TFI) specifically for use with the Saudi population, and to examine reliability and construct validity among adults in senior-living facilities in Saudi Arabia.MethodsA total of 84 community-dwelling older adults were enrolled (mean age = 72 ± 4.7 years). The translation and cross-cultural adaptation of the TFI from English to Arabic was performed using standardized guidelines. Test–retest reliability and internal consistency were examined in two visits, spaced one-week apart. Construct validity of the TFI against other measurements related to frailty was examined. The physical domain for TFI was validated against the Short Physical Performance Battery (SPPB), the timed Up and Go Test (TUG), and gait speed (as part of the SPPB). The psychological domains were validated against the Patient Health Questionnaire, and the social domains were validated against the social domain scores from the WHOQOL-BREF.ResultsThe internal consistency of the TFI with the overall KR-20 was 0.70. For the domain scores KR-20 was 0.68 for the physical, 0.57 for the psychological, and 0.42 for the social. The KR-20 after deletion of each item correlations ranged from 0.66 to 0.72. For the test-retest reliability with one-week interval, the ICC was 0.86 (95 % CI = 0.67–0.94). The Arabic TFI showed statistically significant association with other measurements related to frailty.ConclusionThis study found that the translated Arabic (Saudi) TFI is a valid and reliable instrument in assessing the frailty among Saudi community-dwelling older adults. Our results suggest that the use of this Arabic-translated TFI for clinical screening of frailty in any primary health setting may aid continued understanding for the validity of this instrument and help provide a quantitative diagnostic tool for the prevention and treatment of frailty.     

Prevalence and genotyping of Toxoplasma gondii among Saudi pregnant women in Saudi Arabia

Introduction: Toxoplasma gondii (T. gondii) is an intracellular protozoan that can infect all mammals, who serve as intermediate host. It causes congenital, neurological, eyes complications and mild or asymptomatic infections in humans. Purpose of this study: To investigate not only the prevalence of T. gondii, but also to find out its genotyping using multiple sequential molecular methods to predict exactly the precise genotyping of T. gondii among Saudi pregnant women. Methods: A cross-sectional study was conducted using multi-stage methods. Initial stage involved enrolment of 250 Saudi pregnant women from multi-centre healthcare and community based settings in the capital of Saudi Arabia Riyadh. The second stage was embracement of the laboratory investigation that included Enzyme immunoassay (ELISA), DNA extraction, PCR, nested-PCR assay, and genotyping of the seropositive cases. Results: 203 women agreed to take part in our study with a response rate of 81.2% (203/250). Using ELISA, we found that the prevalence of Toxoplasma gondii IgG and IgM antibodies was 32.5% and 6.4%, respectively. We found that 29 samples (80.6%) were of genotype II; however 7 samples (19.4%) were of genotype III. Conclusion: Defining the population structure of T. gondii from Saudi Arabia has important implications for transmission, immunogenicity, pathogenesis, and in planning preventive strategies. Relationship between such variation in structure and disease manifestation in pregnant women is still difficult to assess due to the role of host immune status and genetic background on the control of infection, and of other parasitic features such as the infecting dose or parasite stage. Our finding of the genotyping of T. gondii might facilitate and inform future studies on comparative genomics and identification of genes that control important biological phenotypes including pathogenesis and transmission among Saudi women.     

Dissemination of VIM-producing Pseudomonas aeruginosa associated with high-risk clone ST654 in a tertiary and quaternary hospital in Makkah,Saudi Arabia

To the best of our knowledge, no molecular surveillance that has been conducted to identify the most common clones of carbapenem-resistant Pseudomonas aeruginosa (CRPA) in western Saudi Arabia. Therefore, this study aimed to identify genetic diversity and the most common CRPA clones in this region. Thirty-five CRPA isolates were collected from a tertiary and quaternary hospital in Makkah. bla _VIM was the most common carbapenemase-encoding gene (11 CRPA isolates), while bla_GES was reported in only three isolates. CRPA isolates were subjected to multi- locus sequence typing and showed relatively high genetic diversity with 20 sequence types. Approximately one-third (31.4%) of the CRPA isolates belonged to two high-risk clones (ST235 and ST654). This troublesome finding raises serious concerns about the emergence and further dissemination of CRPA high-risk clones in local hospitals and suggest that surveillance programs should be established in this region to monitor and control clonal dissemination of all multidrug resistant bacteria, including CRPA.
