RESUMO
BACKGROUND: People with vision impairment encounter many difficulties when it comes to medicines use. However, evidence indicates that there are major gaps in pharmaceutical care service provision worldwide and limited research on interventions to optimise medication use for this patient population. The Theoretical Domains Framework (TDF) provides a method for theoretically understanding individuals' behaviour and informing development of interventions. The aim of this research was to (a) identify the barriers and facilitators to the provision of medication dispensing and counselling services by pharmacists to patients with vision impairment, and (b) identify key TDF domains to be targeted in a future intervention. METHODS: Semi-structured interviews were conducted with pharmacists from different pharmacy practice settings/areas in Saudi Arabia. The 14-domain TDF was utilised as the theoretical lens through which pharmacists' behaviours were examined. Interviews were conducted in Arabic or English, either face-to-face or over the telephone based on the participant's preference. Following transcription, interviews conducted in Arabic were translated into English before analysis. Data analysis involved using the framework method and content analysis to identify important barriers and facilitators to the provision of dispensing and counselling services to those with vision impairment. Key TDF domains that could be targeted in a future intervention were then identified using a consensus-based approach. RESULTS: Twenty-six pharmacists were interviewed. Pharmacists' experience in pharmacy practice ranged from two to 28 years. A range of barriers and facilitators were highlighted as important in providing services to those with vision impairment. Eight domains were identified as 'key domains' including: 'Knowledge', 'Skills', 'Beliefs about capabilities', 'Goals', 'Memory, attention, and decision processes', 'Environmental context and resources', 'Social influences', and 'Behavioural regulation'. CONCLUSIONS: Barriers and facilitators identified by pharmacists will inform the development of an intervention to ensure its applicability to everyday practice. Future research will focus on the process of developing the proposed intervention through targeting key TDF domains to improve medication dispensing and counselling by pharmacists to patients with vision impairment.

Simulated patient (SP) visits followed with structured feedback is useful to outline training needs as well as preference for continuing professional education in community pharmacy settings. This study aimed to investigate community pharmacists' management of an over-the-counter (OTC) product request and feasibility of immediate SP feedback in Jordan. Four trained SP visited a sample of pharmacies in three main urban cities in Jordan requesting an antacid. Information request and professional behavior as well as content of information were evaluated. The SP provided structured immediate feedback. The pharmacy staff views on the visit and usefulness of the feedback were collected. A total of 57 visits were conducted. The average duration of SP visits was 1.55 min. The average score (±SD) for information seeking behavior was 16% (±7) and for professional behavior was 56% (±15). The average score for information provision provided spontaneously was 17.1% (±12). Upon demand by the SP; the average score for information improved to 47.6 (±18). Non-pharmacological advice was not offered often; only 6 (10.5%) visits. Written information was provided in 10 (17.5%) visits. Immediate feedback was accepted by all visited pharmacies. Participants expressed positive views about the SP visit and usefulness of the feedback. Community pharmacists supplied OTC drug without carful screening of symptoms and essential information. The SP approach with immediate feedback was shown feasible and well accepted. Further potential for use of SP with feedback formally in practice and professional development should be explored in future studies.
RESUMO
BACKGROUND: The number of published economic evaluations of Gulf Cooperation Council (GCC) countries is notably scarce. Limited local evidence could have a major impact on the implementation of economic evaluation recommendations in the decision-making process in GCC countries. Little is known about the factors affecting researchers who seek to conduct economic evaluations. Therefore, we aimed to assess researcher barriers and facilitators in conducting such studies of GCC countries. METHODS: A cross-sectional survey of health economic researchers working in GCC countries was conducted online between January and February 2020. The survey instrument collected researchers' perceived barriers and facilitators and demographic information. For barriers, respondents rated their agreement on a 5-point Likert scale ranging from "strongly disagree" to "strongly agree". For facilitators, respondents rated the importance of each facilitator on a six-point scale ranging from "extremely important" to "not very important". Then, participants were asked to select the three most important barriers and facilitators from the lists. The data collected were examined using descriptive analysis. RESULTS: Fifty-one researchers completed the survey (37% response rate). The majority of participants (more than 80%) agreed that lack of quality of effectiveness data and restricted access to unit cost data are the main barriers to conducting economic research. Availability of relevant local data was reported as an important facilitator, followed by collaboration between health economic researchers, policy-makers and other stakeholders. CONCLUSIONS: The results of this study provide an exploratory view of the issues faced by health economics researchers in GCC countries. Recommendations to GCC countries based on international experiences, such as to use real-world data in economic evaluation research, were provided.

BACKGROUND: Poor adherence to antiepileptic medication is associated with increased mortality, morbidity and healthcare costs. In this review, we focus on interventions designed and tested in randomised controlled trials (RCTs) and quasi-RCTs to assist people with adherence to antiepileptic medication. This is an update of a Cochrane review first published in 2011, and last updated in 2017. OBJECTIVES: To determine the effectiveness of interventions aimed at improving adherence to antiepileptic medication in adults and children with epilepsy. SEARCH METHODS: For the latest update, we searched the following databases on 18 February 2020: Cochrane Register of Studies (CRS Web), MEDLINE, CINAHL Plus and PsycINFO. CRS Web includes RCTs or quasi-RCTs from PubMed, Embase, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (ICTRP), CENTRAL, and the Specialized Registers of Cochrane Review Groups including Epilepsy. We also searched the reference lists of relevant articles. SELECTION CRITERIA: RCTs and quasi-RCTs of adherence-enhancing interventions aimed at people with a clinical diagnosis of epilepsy (as defined in individual studies), of any age and treated with antiepileptic drugs in a primary care, outpatient or other community setting. DATA COLLECTION AND ANALYSIS: All review authors independently assessed lists of potentially relevant citations and abstracts. At least two review authors independently extracted data and performed a quality assessment of each study according to the Cochrane tool for assessing risk of bias. We graded the level of evidence for each outcome according to GRADE. The studies differed widely according to the type of intervention and measures of adherence; therefore combining data was not appropriate. MAIN RESULTS: We included 20 studies reporting data on 2832 participants. Thirteen studies targeted adults with epilepsy, one study included participants of all ages, one study included participants older than two years, one recruited pediatric patients aged between 1 month to 15 years, one study targeted caregivers of children with epilepsy, one targeted adolescents and caregivers, and two studies targeted families of children with epilepsy. We identified three ongoing studies. Follow-up time was generally short in most studies, ranging from 1 to 12 months. The studies examined three main types of interventions: educational interventions, behavioural interventions and mixed interventions. All but three studies compared treatment with usual care or 'no intervention'. Due to heterogeneity between studies in terms of interventions, methods used to measure adherence and the way the studies were reported, we did not pool the results and these findings were inappropriate to be included in a meta-analysis. Education and counselling of participants with epilepsy had mixed success (moderate-certainty evidence). Behavioural interventions such as the use of intensive reminders provided more favourable effects on adherence (moderate-certainty evidence). The effect on adherence to antiepileptic drugs described by studies of mixed interventions showed improved adherence in the intervention groups compared to the control groups (high-certainty evidence). Eleven studies described seizure frequency or seizure severity or both, with four of them, reporting improved adherence and decreased seizure frequency in the intervention groups (moderate-certainty evidence). Findings related to self-efficacy and quality of life were mixed, with no clear pattern across types of intervention. AUTHORS' CONCLUSIONS: Behavioural interventions such as intensive reminders and the use of mixed interventions demonstrate some positive results, however, we need more reliable evidence on their efficacy, derived from carefully-designed RCTs before we can draw a firm conclusion. None of the newly included studies have provided additional information that would lead to significant changes in our conclusions.

Transgenic alfalfa (Medicago sativa L.) plants overexpressing the Arabidopsis ATP sulfurylase gene were generated using Agrobacterium-mediated genetic transformation to enhance their heavy metal accumulation efficiency. The ATP sulfurylase gene was cloned from Arabidopsis, following exposure to vanadium (V) and lead (Pb), and transferred into an Agrobacterium tumefaciens binary vector. This was co-cultivated with leaf explants of the alfalfa genotype Regen SY. Co-cultivated leaf explants were cultured on callus and somatic embryo induction medium, followed by regeneration medium for regenerating complete transgenic plants. The transgenic nature of the plants was confirmed using PCR and southern hybridization. The expression of Arabidopsis ATP sulfurylase gene in the transgenic plants was evaluated through RT-PCR. The selected transgenic lines showed increased tolerance to a mixture of five heavy metals and also demonstrated enhanced metal uptake ability under controlled conditions. The transgenic lines were fertile and did not exhibit any apparent morphological abnormality. The results of this study indicated an effective approach to improve the heavy metal accumulation ability of alfalfa plants which can then be used for the remediation of contaminated soil in arid regions.

Retinal dystrophies (RDs) are hereditary blinding eye conditions that are highly variable in their clinical presentation. The remarkable genetic heterogeneity that characterizes RD was a major challenge in establishing the molecular diagnosis in these patients until the recent advent of next-generation sequencing. It remains unclear, however, what percentage of autosomal recessive RD remain undiagnosed when all established RD genes are sequenced. We enrolled 75 families in which RD segregates in an apparently autosomal recessive manner. We show that the yield of a multigene panel that contains known RD genes is 67.5%. The higher yield (82.3%) when whole exome sequencing was implemented instead was often due to hits in genes that were not included in the original design of the panel. We also show the value of homozygosity mapping even during the era of exome sequencing in uncovering cryptic mutations. In total, we describe 45 unique likely deleterious variants (of which 18 are novel including one deep intronic and one genomic deletion mutation). Our study suggests that the genetic heterogeneity of autosomal recessive RD is approaching saturation and that any new RD genes will probably account for only a minor role in the mutation burden.

The genome of sida golden mottle virus (SiGMoV) (GU997691 and GU997692) isolated from Sida santaremensis Monteiro in Manatee County, Florida, was sequenced and characterized. SiGMoV was determined to be a bipartite virus belonging to the genus Begomovirus with a genome organization typical of the New World viruses in the genus. SiGMoV DNA-A had the highest identity scores (89%) and showed the closest evolutionary relationships to sida golden mosaic Buckup virus (SiGMBuV) (JX162591 and HQ008338). However, SiGMoV DNA-B had the highest identity scores (93%) and showed the closest evolutionary relationship to corchorus yellow spot virus (DQ875869), SiGMBuV (JX162592) and sida golden mosaic Florida virus (SiGMFlV) (HE806443). There was extensive recombination in the SiGMoV DNA-A and much less in DNA-B. Full-length clones of SiGMoV were infectious and were able to infect and cause symptoms in several plant species.

BACKGROUND: Poor adherence to antiepileptic medication is associated with increased mortality, morbidity and healthcare costs. In this review, we focus on interventions designed and tested in randomised controlled trials and quasi-randomised controlled trials to assist people with adherence to antiepileptic medication. This is an updated version of the original Cochrane review published in the Cochrane Library, Issue 1, 2010. OBJECTIVES: To determine the effectiveness of interventions aimed at improving adherence to antiepileptic medication in adults and children with epilepsy. SEARCH METHODS: For the latest update, on 4 February 2016 we searched the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO), MEDLINE (Ovid 1946 to 4 February 2016), CINAHL Plus (EBSCOhost 1937 to 4 February 2016), PsycINFO (EBSCOhost 1887 to 4 February 2016), ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform. We also searched the reference lists of relevant articles. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials of adherence-enhancing interventions aimed at people with a clinical diagnosis of epilepsy (as defined in individual studies), of any age and treated with antiepileptic drugs in a primary care, outpatient or other community setting. DATA COLLECTION AND ANALYSIS: All review authors independently assessed lists of potentially relevant citations and abstracts. At least two review authors independently extracted data and performed quality assessment of each study according to the Cochrane tool for assessing risk of bias. We graded the level of evidence for each outcome according to the GRADE working group scale.The studies differed widely according to the type of intervention and measures of adherence; therefore combining data was not appropriate. MAIN RESULTS: We included 12 studies reporting data on 1642 participants (intervention = 833, control = 809). Eight studies targeted adults with epilepsy, one study included participants of all ages, one study included participants older than two years, one study targeted caregivers of children with epilepsy, and one study targeted families of children with epilepsy. We identified six ongoing trials. Follow-up time was generally short in most trials, ranging from one to 12 months. The trials examined three main types of interventions: educational interventions, behavioural interventions and mixed interventions. All studies compared treatment versus usual care or 'no intervention', except for two studies. Due to heterogeneity between studies in terms of interventions, methods used to measure adherence and the way the studies were reported, we did not pool the results and these findings were inappropriate to be included in a meta-analysis.

Since the last version of this review, none of the new relevant studies have provided additional information that would lead to significant changes in our conclusions. This current update includes 12 studies, of which six came from the latest searches.

BACKGROUND: The barnacle Balanus amphitrite is widely distributed in marine shallow and tidal waters, and has significant economic and ecological importance. Nauplii, the first larval stage of most crustaceans, are extremely abundant in the marine zooplankton. However, a lack of genome information has hindered elucidation of the molecular mechanisms of development, settlement and survival strategies in extreme marine environments. We sequenced and constructed the genome dataset for nauplii to obtain comprehensive larval genetic information. We also investigated iTRAQ-based protein expression patterns to reveal the molecular basis of nauplii development, and to gain information on larval survival strategies in the Red Sea marine environment. RESULTS: A nauplii larval transcript dataset, containing 92,117 predicted open reading frames (ORFs), was constructed and used as a reference for the proteome analysis. Genes related to translation, oxidative phosphorylation and cytoskeletal development were highly abundant. We observed remarkable plasticity in the proteome of Red Sea larvae. The proteins associated with development, stress responses and osmoregulation showed the most significant differences between the two larval populations studied. The synergistic overexpression of heat shock and osmoregulatory proteins may facilitate larval survival in intertidal habitats or in extreme environments. CONCLUSIONS: We presented, for the first time, comprehensive transcriptome and proteome datasets for Red Sea nauplii. The datasets provide a foundation for future investigations focused on the survival mechanisms of other crustaceans in extreme marine environments.

Although biallelic mutations in non-collagen genes account for <10% of individuals with osteogenesis imperfecta, the characterization of these genes has identified new pathways and potential interventions that could benefit even those with mutations in type I collagen genes. We identified mutations in FKBP10, which encodes the 65 kDa prolyl cis-trans isomerase, FKBP65, in 38 members of 21 families with OI. These include 10 families from the Samoan Islands who share a founder mutation. Of the mutations, three are missense; the remainder either introduce premature termination codons or create frameshifts both of which result in mRNA instability. In four families missense mutations result in loss of most of the protein. The clinical effects of these mutations are short stature, a high incidence of joint contractures at birth and progressive scoliosis and fractures, but there is remarkable variability in phenotype even within families. The loss of the activity of FKBP65 has several effects: type I procollagen secretion is slightly delayed, the stabilization of the intact trimer is incomplete and there is diminished hydroxylation of the telopeptide lysyl residues involved in intermolecular cross-link formation in bone. The phenotype overlaps with that seen with mutations in PLOD2 (Bruck syndrome II), which encodes LH2, the enzyme that hydroxylates the telopeptide lysyl residues. These findings define a set of genes, FKBP10, PLOD2 and SERPINH1, that act during procollagen maturation to contribute to molecular stability and post-translational modification of type I procollagen, without which bone mass and quality are abnormal and fractures and contractures result.

While whitefly-transmitted begomoviruses are economically important constraints to tomato production in Kuwait, little is known about genomic features of these viruses from Kuwait. A begomovirus isolated from severely diseased tomatoes, collected over a two-year period in the main tomato-growing areas of Kuwait, was characterized at the molecular level. The complete genomic sequence of the begomovirus was determined, and phlylogeographic studies were conducted to better understand genetic diversity of the virus in the region. Based on genome properties and phylogenetic analysis, the begomovirus was found to be a strain of tomato yellow leaf curl virus (TYLCV). The virus genome was monopartite, as neither DNA B nor satellite DNA molecules were detected. Two isolates characterized in this study shared 97% and 95% nucleotide sequence identity with a previously characterized Kuwaiti isolate, TYLCV-KISR. Among TYLCV isolates with known genome sequences, the Kuwaiti isolates shared highest sequence identity (95%) with TYLCV-Almeria (Spain). Genetic diversity and phylogenetic analysis showed that the three Kuwaiti isolates formed a distinct clade that was separate from those of known TYLCV sequences. One Kuwaiti isolate (KW 1-3) could be a novel variant of TYLCV. Two recombination events were detected in the genome sequence of KW 1-3, which appeared to be a recombinant derived from TYLCV parents from Oman and Kuwait.

INTRODUCTION: Nonadherence to antiseizure medications (ASMs) is associated with increased mortality, morbidity, health care utilization, and costs. AREAS COVERED: This article reviewed 18 randomized controlled trials published between Jan 2010 and Feb 2024 on Medication Adherence Enhancing Intervention (MAEI) for people with epilepsy. The adequacy of reporting intervention development process was assessed using the GUIDance for the rEporting of intervention Development (GUIDED). The adequacy of the intervention description was assessed using the Template for Intervention Description and Replication (TIDieR) checklist. The interventions were categorized as educational (n = 7), behavioral (n = 5), or mixed (n = 6). The impact of MAEIs on adherence is mixed with majority of studies either reporting no difference between intervention and control groups (n = 6) or improvement in the intervention group (n = 7). The shortcomings in the reporting of MAEIs development, MAEIs description, and MAEIs impact measurement were discussed. EXPERT OPINION: Future research needs to accomplish the following tasks: 1) develop and test valid epilepsy-specific self-report measures for assessing adherence; 2) optimize intervention design; and 3) increase transparency in reporting all stages of research.

INTRODUCTION: This overview aimed to find, assess, and synthesize systematic reviews that compared the cost-effectiveness of interventions designed to improve medication adherence among patients with chronic disease. AREAS COVERED: PubMed, Web of Science, Cochrane Database of Systematic Reviews, and Center for Review and Dissemination were searched. The quality of the included reviews was assessed using two validated checklists. The review characteristics and findings were summarized narratively. A total of 9 systematic reviews were included. Interventions reported to be cost-effective were simplification of the medication regimen, financial incentives, improved coverage or reduced out-of-pocket spending, and pharmacist care. The most common interventions were patient education and counseling, with mixed results of cost-effectiveness. This evidence comes from economic evaluations with varying degrees of quality. EXPERT OPINION: Future evaluations of adherence interventions' cost-effectiveness will be improved in quality as our understanding of the reasons behind intentional and unintentional nonadherence and factors associated with this behavior advances. The development of criteria for the value assessment of medication adherence-enhancing interventions will contribute to improving the quality of adherence intervention cost-effectiveness research.

BACKGROUND: This review aimed to 1) identify and assess the quality of discrete choice experiments (DCEs) examining preferences related to epilepsy treatment; 2) summarize the attributes and attribute levels measured in these studies; 3) identify how researchers selected and developed these attributes; and 4) identify which attributes are most important for epilepsy patients. METHODS: A systematic literature review using PubMed, Web of Science and Scopus databases from database inception to February or April 2022. We included primary discrete-choice experiments eliciting preferences for various attributes of pharmacological and surgical interventions in patients diagnosed with epilepsy or the parents/carers of children with epilepsy. We excluded non- primary studies, studies assessing preferences for nonpharmacological treatment and studies that elicit preferences using methods other than discrete choice experiments. Two authors independently selected studies, extracted data and assessed risk of bias of studies. The quality of the included studies was assessed using two validated checklists. Study characteristics and findings were summarized descriptively. RESULTS: A total of seven studies were included in the review. The majority of studies explored patients' preferences, and two compared the preferences of patients with physicians. The majority (n = 6) compared two medications, and one compared two surgical options to continuing medication options. The studies examined 44 attributes in total, including side effects (n = 26), efficacy expressed as being seizure free or have fewer seizures (n = 8), costs (n = 3), dosing frequency (n = 3), duration of side effects (n = 2), mortality (n = 1), long-term problems after surgery (n = 1) and surgical options (n = 1). The findings indicate that people with epilepsy have strong preferences for improving seizure control, which was ranked as the top priority in all studies. Patients also have a strong preference for the reduction of adverse effects and may be willing to make trade-offs between improved seizure control and reduction of long-term side effects that may impact their quality of life. CONCLUSIONS: The use of DCEs in measuring patients' preference for epilepsy treatment is accumulating. However, inadequate reporting of methodological details may reduce decision-makers' confidence in the findings. Suggestions for future research are provided.
RESUMO
To evaluate the potential role of in situ formed Sr-Ti-O species as a ferroelectric component able to enhance the photocatalytic properties of an adjacent TiO2 semiconductor, Cu-doped/graphene oxide (GO)/TiO2 nanotubes (TiNTs) composites (with 0.5 wt % Cu and 1.0 wt % GO) have been synthesized while progressive amounts of strontium (up to 1.0 wt %) were incorporated at the surface of the composite through incipient wetness impregnation followed by post-thermal treatment at 400 °C. The different resulting photocatalytic systems were then first deeply characterized by means of N2 adsorption-desorption measurements, X-ray diffraction (XRD), UV-vis diffuse reflectance (UV-vis DR), Raman and photoluminescence (PL) spectroscopies, and scanning electron microscopy (SEM) (with energy-dispersive X-ray (EDX) spectroscopy and Z-mapping). In a second step, optimization of the kinetic response of the Sr-containing composites was performed for the formic acid photodegradation under UV irradiation. The Sr-containing Cu/GO/TiNT composites were then fully characterized by electrochemical impedance spectroscopy (EIS) for their dielectric properties showing clearly the implication of polarization induced by the Sr addition onto the stabilization of photogenerated charges. Finally, a perfect correlation between the photocatalytic kinetic evaluation and dielectric properties undoubtedly emphasizes the role of ferroelectric polarization as a very valuable approach to enhance the photocatalytic properties in an adjacent semiconductor.
RESUMO
OBJECTIVE: Whitefly-transmitted tomato yellow leaf curl virus (TYLCV) continues to be a major constraint to tomato production in Kuwait. However, very limited information is available about the population structure and genetic diversity of TYLCV infecting tomato in Kuwait. RESULTS: Whole genome sequences of 31 isolates of TYLCV, collected from commercial tomato crops grown in northern (Abdally) and southern (Al Wafra) parts of Kuwait, were deciphered. Eighteen isolates of TYLCV are identified as potential genetic recombinants. The isolates Abdally 6A and Abdally 3B reported in this study were identified to be potential recombinants. Compared to the 15 isolates from the Abdally area, and the three previously reported KISR isolates of Kuwait, six out of sixteen Al Wafra isolates showed an insertion of 19 extra nucleotides near the 5'-end. There are also four nucleotide variations before the 19-extra-nucleotides. The additional 19 nucleotides observed in nine isolates indicate that these isolates might have resulted from a single gene recombination/insertion event. Molecular phylogeny based on complete genome sequences of TYLCV isolates suggests transboundary movement of virus isolates due to geographic proximity. The information presented herein is quite useful for the comprehension of TYLCV biology, epidemiology and would aid in the management of disease in the long run.

Emergency department staff are at high risk of experiencing violence and aggression from patients and visitors, which can have negative impacts on healthcare providers in the ED. The aim of this study was to explore the role of healthcare providers in addressing local violence in Riyadh EDs and investigate their preparedness for managing violent incidents. We used a descriptive, correlational design with survey methodology to collect data from a convenience sample of nurses, ED technicians, physicians, and advanced practice providers in Riyadh city's EDs. To examine the associations, we used an analysis of variance (ANOVA) for unadjusted relationships and an analysis of covariance (ANCOVA) for adjusted associations. Measures included a demographic survey, and clinicians responded to an online survey. A total of 206 ED staff participated in the questionnaire, and 59% reported experiencing physical violence during an ED shift, with 61% of incidents being caused by relatives. Additionally, 32% of the participants witnessed workplace violence. Our findings revealed that male healthcare workers, physicians, and those working in the governmental sector were at the highest risk of experiencing violence. We also found a statistically significant association between the rate of patients seen in the ED and the frequency of assault (physical or verbal) in the ED. Our results suggest that the rate of workplace violence in Riyadh EDs is high, and more efforts are needed to protect the health and well-being of healthcare providers. Senior management should take a position against ED domestic violence and reinforce managerial and healthcare provider resources by adopting policies and procedures that protect healthcare workers' safety. This study provides valuable insights into the nature and prevalence of violence in Riyadh EDs and highlights the critical role of healthcare providers in reducing violence in EDs.
RESUMO
The magnitude of post-COVID-19 syndrome was not thoroughly investigated. This study evaluated the quality of life and persistence of fatigue and physical symptoms of individuals post-COVID-19 compared with noninfected controls. The study included 965 participants; 400 had previous COVID-19 disease and 565 controls without COVID-19. The questionnaire collected data on comorbidities, COVID-19 vaccination, general health questions, and physical symptoms, in addition to validated measures of quality of life (SF-36 scale), fatigue (fatigue severity scale, FSS), and dyspnea grade. COVID-19 participants complained more frequently of weakness, muscle pain, respiratory symptoms, voice disorders, imbalance, taste and smell loss, and menstrual problems compared to the controls. Joint symptoms, tingling, numbness, hypo/hypertension, sexual dysfunction, headache, bowel, urinary, cardiac, and visual symptoms did not differ between groups. Dyspnea grade II-IV did not differ significantly between groups (p = 0.116). COVID-19 patients scored lower on the SF-36 domains of role physical (p = 0.045), vitality (p < 0.001), reported health changes (p < 0.001), and mental-components summary (p = 0.014). FSS scores were significantly higher in COVID-19 participants (3 (1.8-4.3) vs. 2.6 (1.4-4); p < 0.001). COVID-19 effects could persist beyond the acute infection phase. These effects include changes in quality of life, fatigue, and persistence of physical symptoms.
RESUMO
OBJECTIVES: To measure psychiatrists' experience and their expectations of the role of clinical pharmacists in Riyadh, Saudi Arabia. SUBJECTS AND METHODS: The psychiatrists' experience and their expectations were collected using a 4-part self-completed questionnaire: (a) demographic information, (b) psychiatrists' current expectations of the roles of pharmacists, (c) psychiatrists' actual experience with pharmacists, and (d) psychiatrists' future expectations of pharmacists' roles. Each part included a set of statements for which respondents were asked to indicate their level of agreement using a 5-point Likert scale. RESULTS: Of the 102 questionnaires delivered to the Department of Psychiatry at 7 hospitals, 77 were returned, representing a response rate of 75%. 59 (77%) psychiatrists expected pharmacists to take personal responsibility for resolving any drug-related problems; 62 (81%) expected them to maintain a complete medication profile, and 58 (75%) expected them to educate patients about the safety and appropriate use of their medication. From their current experience with pharmacists, respondents indicated that pharmacists routinely counsel patients (33, 43%), inform them about the most cost-effective alternative (37, 48%), and discuss with them the therapeutic value of the drugs (37, 48%). 49 (63%) of respondents agreed that in the future, pharmacists should routinely adjust the drug therapy for patients under protocol approved by the physician, and 51 (66%) felt that pharmacists should share legal responsibility for clinical outcomes. CONCLUSION: Psychiatrists in Riyadh had great expectations of clinical pharmacists to take personal responsibility for resolving drug-related problems they discovered and to assist in designing drug therapy treatment plans.

UNLABELLED: The anemia of end stage renal disease (ESRD) is common and often severe complication that can be managed successfully by erythropoiesis-stimulating agents (ESA) administration. AIMS: To investigate current practice of anemia management in hemodialysis patients and to assess the appropriateness of anemia management by comparing observed practice to the Kidney Disease Outcomes Quality Initiative (KDOQI) guideline recommendations. SETTINGS AND DESIGN: The study was conducted at two hemodialysis centers in Riyadh, Saudi Arabia. Data on anemia parameters, comorbidities, ESA dosing and iron supplementation were collected. The data were collected for 7 months retrospectively from April to the end of May 2008 and prospectively from June to October 2008. Patients who were over 18 years of age with ESRD undergoing hemodialysis were included. Patients were excluded if they have cancer or receiving chemotherapy or radiotherapy. RESULTS: Data were collected from 87 patients. Mean Hgb value for those patients was 11.16 ± 0.97 g/dL. Thirty-nine patients (45%) had mean Hgb values between 11.0 and 12.0 g/dL the target range recommended by KDOQI guideline. The mean weekly prescribed dose of erythropoietin was 8099 ± 5946 IU/Week (135 ± 99 IU/kg/Week). Information on ferritin concentrations was available for 48 (55%) patients. The mean serum ferritin concentration for those patients was 693 ± 420.5 ng/mL. Fifty-two patients had transferrin saturation (TSAT) values recorded. The mean TSAT value was 38.5 ± 19.7%. CONCLUSIONS: There is an opportunity to improve anemia management in hemodialysis patients particularly thorough evaluation of causes of inadequate response rate and better monitoring and management of iron status.
