Attitudes and barriers towards conducting research amongst primary care physicians in Bahrain: a cross-sectional study.

BACKGROUND: Research in primary care is essential for disease diagnosis, management and prevention in relation to the individuals, families and the community. This research aims to study the attitude of primary care physicians towards conducting research in Bahrain and to identify the main barriers encountered during research. METHODS: A cross-sectional study was conducted amongst 200 randomly selected primary care physicians registered in Ministry of Health affiliated primary healthcare centers in Bahrain. A self-administered validated questionnaire was adopted and used for data collection. Research data was analyzed using the Statistical Package for Social Sciences (SPSS) version 23. RESULTS: Primary care physicians had a positive attitude towards conducting research with a total mean score (SD) of 4.47(0.65) (on a scale from 1 to 5 with higher scores indicating more positive attitudes). The total mean score (SD) for barriers encountered by physicians during research was 3.34 (0.80). Insufficient research allotted time (76.5%), insufficient financial support (63%), lack of financial incentives (51%) and lack of statistical support (50%) were major barriers. Physicians designation and board certificate were significantly associated with attitudes and barriers towards research (P-value < 0.05). CONCLUSION: The majority or primary care physicians had positive attitudes towards conducting research. The major difficulties faced by physicians in conducting research are: Insufficient research allotted time, lack of financial incentives and inadequate statistical support. The study addressed a gap in building research capacity which should be embraced by many institutions through partnership and collaboration.

Comparative transcriptional and anatomical analyses of tolerant rough lemon and susceptible sweet orange in response to 'Candidatus Liberibacter asiaticus' infection.

Although there are no known sources of genetic resistance, some Citrus spp. are reportedly tolerant to huanglongbing (HLB), presumably caused by 'Candidatus Liberibacter asiaticus'. Time-course transcriptional analysis of tolerant rough lemon (Citrus jambhiri) and susceptible sweet orange (C. sinensis) in response to 'Ca. L. asiaticus' infection showed more genes differentially expressed in HLB-affected rough lemon than sweet orange at early stages but substantially fewer at late time points, possibly a critical factor underlying differences in sensitivity to 'Ca. L. asiaticus'. Pathway analysis revealed that stress responses were distinctively modulated in rough lemon and sweet orange. Although microscopic changes (e.g., callose deposition in sieve elements and phloem cell collapse) were found in both infected species, remarkably, phloem transport activity in midribs of source leaves in rough lemon was much less affected by HLB than in sweet orange. The difference in phloem cell transport activities is also implicated in the differential sensitivity to HLB between the two species. The results potentially lead to identification of key genes and the genetic mechanism in rough lemon to restrain disease development and maintain (or recover) phloem transport activity. These potential candidate genes may be used for improving citrus tolerance (or even resistance) to HLB by genetic engineering.

Infection prevention and control staffing and programs in Middle Eastern Countries.

INTRODUCTION: Infection prevention and control (IPC) programs in the Middle Eastern and North African (MENA) countries are evolving. The objective was to characterize IPC personnel and programs in MENA countries, with special emphasis on the differences between Gulf Cooperation Council (GCC) and non-GCC countries. METHODOLOGY: A cross-sectional online survey was conducted in 2019 among IPC members of the Arab Countries Infection Control Network (AcicN). The survey focused on three domains; demographic and professional characteristics, organizational structure, and IPC program characteristics. RESULTS: A total of 269 participants aged 39.9 ± 8.4 years were included in the study. Majority of the participants were females (67.7%), nurses (63.7%), and of Middle-Eastern origin (57.3%). 32.2% of the participants were certified by the Certification Board of Infection Control (CBIC). Only 22.7% of participants were satisfied with their current compensation. Surveillance was the most time-consuming task (26.6%), followed by isolation (12.4%), and investigation of outbreaks (12.1%). Majority of the facilities had at least one IPC personnel per 100 beds (60.9%), supported IPC program (63.9%), a formal IPC committee (93.7%), and an IPC plan (91.4%). Compared with non-GCC countries, GCC countries had significantly more frequent CBIC certification (p = 0.003), training in cleaning/sterilization (p = 0.010), supported IPC program (p = 0.010), formal IPC committee (p = 0.001), IPC plan (p = 0.001), and higher number of IPC personnel per 100 beds (p = 0.047). CONCLUSIONS: MENA countries had generally satisfactory IPC programs and to a lesser extent staffing, with considerable variability between countries with different resources.

Fortunella margarita transcriptional reprogramming triggered by Xanthomonas citri subsp. citri.

BACKGROUND: Citrus canker disease caused by the bacterial pathogen Xanthomonas citri subsp. citri (Xcc) has become endemic in areas where high temperature, rain, humidity, and windy conditions provide a favourable environment for the dissemination of the bacterium. Xcc is pathogenic on many commercial citrus varieties but appears to elicit an incompatible reaction on the citrus relative Fortunella margarita Swing (kumquat), in the form of a very distinct delayed necrotic response. We have developed subtractive libraries enriched in sequences expressed in kumquat leaves during both early and late stages of the disease. The isolated differentially expressed transcripts were subsequently sequenced. Our results demonstrate how the use of microarray expression profiling can help assign roles to previously uncharacterized genes and elucidate plant pathogenesis-response related mechanisms. This can be considered to be a case study in a citrus relative where high throughput technologies were utilized to understand defence mechanisms in Fortunella and citrus at the molecular level. RESULTS: cDNAs from sequenced kumquat libraries (ESTs) made from subtracted RNA populations, healthy vs. infected, were used to make this microarray. Of 2054 selected genes on a customized array, 317 were differentially expressed (P < 0.05) in Xcc challenged kumquat plants compared to mock-inoculated ones. This study identified components of the incompatible interaction such as reactive oxygen species (ROS) and programmed cell death (PCD). Common defence mechanisms and a number of resistance genes were also identified. In addition, there were a considerable number of differentially regulated genes that had no homologues in the databases. This could be an indication of either a specialized set of genes employed by kumquat in response to canker disease or new defence mechanisms in citrus. CONCLUSION: Functional categorization of kumquat Xcc-responsive genes revealed an enhanced defence-related metabolism as well as a number of resistant response-specific genes in the kumquat transcriptome in response to Xcc inoculation. Gene expression profile(s) were analyzed to assemble a comprehensive and inclusive image of the molecular interaction in the kumquat/Xcc system. This was done in order to elucidate molecular mechanisms associated with the development of the hypersensitive response phenotype in kumquat leaves. These data will be used to perform comparisons among citrus species to evaluate means to enhance the host immune responses against bacterial diseases.

The use of complementary and alternative medicine by patients with diabetes mellitus in Bahrain: a cross-sectional study.

BACKGROUND: CAM use is widespread, especially among patients with diabetes. The Gulf States have a high prevalence of diabetes, alongside a long tradition of CAM use. The aim of this study is to establish the prevalence of CAM use among patients with diabetes mellitus in Bahrain and to examine the characteristics of the CAM users. METHODS: A questionnaire was developed and administered to a convenience sample of patients with diabetes (n = 402) above the age of 20 attending two hospital diabetes clinics. Data were analysed using descriptive statistics and non-parametric tests of association. RESULTS: 63% of responders utilized CAM within the previous 12 months. CAM users were more likely to be female, to have had diabetes for longer and to have complications of their diabetes. 64% of CAM users stated that they had used CAM for managing their diabetic condition, with 46% of these having used it solely for their diabetes. Respondents using CAM to manage their diabetes were more likely to be male, to be using CAM on a daily basis and to have informed their physician of their CAM use. CONCLUSIONS: There is a high rate of CAM use in patients with diabetes attending two hospital diabetes clinics in Bahrain. There is also a high rate of non-disclosure of CAM use to physicians. There is a continuing need for health professionals to be more aware and better trained in order to inform their decision making and communication related to CAM use.
