OBJECTIVE: In healthy adults, the short-term effects of sleep disruption include disorders of mood, impaired coping ability, deficits in cognition, and reduced quality of life. Increased physical activity may improve sleep duration and quality. The aim was to investigate the physical activity level and sleep quality and their relationship among a cohort of healthy females in Egypt. PATIENTS AND METHODS: We conducted a cross-sectional, self-reported survey. 688 healthy young adult females aged 18-45 years without a prior history of chronic disease were recruited for this study. Demographic data as well as physical activity (International Physical Activity Questionnaire) and sleep quality (Pittsburgh Sleep Quality Index) were collected. RESULTS: 73.5% reported poor sleep quality, which was worse for housewives. 50.4% of participants were either obese or overweight. Approximately 29.7% of the participants were physically inactive. High physical activity levels were associated with higher sleep efficiency compared to moderate physical activity (p=0.01). However, high physical activity resulted in poorer sleep quality overall (p=0.001). CONCLUSIONS: The majority of participants reported poor sleep quality and high levels of physical activity, but the relationship between physical activity and sleep quality was not clear. Poor sleep quality in our study is one of, if not the highest, reported in the literature for a similar age range in females. [ABSTRACT FROM AUTHOR]

Chesnut III (9) Keywords: Key words:Bone mineral density -- Osteoporosis -- Risedronate -- Vertebral fracture Abstract: Risedronate treatment reduces the risk of vertebral fracture in women with existing vertebral fractures, but its efficacy in prevention of the first vertebral fracture in women with osteoporosis but without vertebral fractures has not been determined. We examined the risk of first vertebral fracture in postmenopausal women who were enrolled in four placebo-controlled clinical trials of risedronate and who had low lumbar spine bone mineral density (BMD) (mean T-score =--3.3) and no vertebral fractures at baseline. Subjects received risedronate 5 mg (n= 328) or placebo (n= 312) daily for up to 3 years all subjects were given calcium (1000 mg daily), as well as vitamin D supplementation (up to 500 IU daily) if baseline serum 25-hydroxyvitamin D levels were low. The incidence of first vertebral fracture was 9.4% in the women treated with placebo and 2.6% in those treated with risedronate 5 mg (risk reduction of 75%, 95% confidence interval 37% to 90% P= 0.002). The number of patients who would need to be treated to prevent one new vertebral fracture is 15. When subjects were stratified by age, similar significant reductions were observed in patients with a mean age of 64 years (risk reduction of 70%, 95% CI 8% to 90% P= 0.030) and in those with a mean age of 76 years (risk reduction of 80%, 95% CI 7% to 96% P= 0.024). Risedronate treatment therefore significantly reduces the risk of first vertebral fracture in postmenopausal women with osteoporosis, with a similar magnitude of effect early and late after the menopause.

Background: Applying proper first-aid measures to patients with seizure episodes plays a vital role in preventing the adverse consequences of seizures. Most previous data focused on teachers, healthcare providers and the general public. This study aimed to assess the knowledge of seizure first-aid measures among undergraduate health students., Methods: This descriptive, cross-sectional study was conducted between May 16 and 31, 2023, with 493 undergraduate health students of Riyadh Province who answered online surveys. The data were collected using the descriptive information form. The chi-square (χ 2 ) test was employed to compare knowledge of seizure first aid between demographic variables. The relationship between knowledge score and independent variables was evaluated using multiple linear regression technique., Results: Only 1.6 % of participants demonstrated good knowledge scores toward seizure first-aid measures. The skill most frequently reported was to remove all harmful objects from their vicinity and loosen the tight clothes around the neck during a seizure; 68.7 % of the participants correctly answered with agreed. Conversely, the skill that received the lowest knowledge score among participants was putting a piece object such as a cloth, wallet, or spoon between the teeth to prevent tongue biting during a seizure; only 37.3 % of the participants correctly answered with disagree. Moreover, participants in the advanced age group, medicine and fifth-year, were found to be significant predictors of knowledge and exhibited better knowledge scores toward seizure first aid measures than their peers (p < 0.001). Furthermore, lectures and books were identified (69.6 %) as the most common source of information about seizure first aid., Conclusion: The study concluded that most undergraduate health students demonstrated poor knowledge scores in delivering seizure first aid. This finding suggests that introducing epilepsy education from the first year in all health-related courses is crucial to improving overall awareness and skills in providing seizure first aid., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

There is growing evidence that comprehensive and harmonized metadata are fundamental for effective public data reusability. However, it is often challenging to extract accurate metadata from public repositories. Of particular concern is the metagenomic data related to African individuals, which often omit important information about the particular features of these populations. As part of a collaborative consortium, H3ABioNet, we created a web portal, namely the African Human Microbiome Portal (AHMP), exclusively dedicated to metadata related to African human microbiome samples. Metadata were collected from various public repositories prior to cleaning, curation and harmonization according to a pre-established guideline and using ontology terms. These metadata sets can be accessed at https://microbiome.h3abionet.org/. This web portal is open access and offers an interactive visualization of 14 889 records from 70 bioprojects associated with 72 peer reviewed research articles. It also offers the ability to download harmonized metadata according to the user's applied filters. The AHMP thereby supports metadata search and retrieve operations, facilitating, thus, access to relevant studies linked to the African Human microbiome.

Dyslipidemia refers to unhealthy changes in blood lipid composition and is a risk factor for atherosclerotic cardiovascular diseases (ASCVD). Usually, low-density lipoprotein-cholesterol (LDL-C) is the primary goal for dyslipidemia management. However, non-high-density lipoprotein cholesterol (non-HDL-C) has gained attention as an alternative, reliable goal. It encompasses all plasma lipoproteins like LDL, triglyceride-rich lipoproteins (TRL), TRL-remnants, and lipoprotein a [Lp(a)] except high-density lipoproteins (HDL). In addition to LDL-C, several other constituents of non-HDL-C have been reported to be atherogenic, aiding the pathophysiology of atherosclerosis. They are acknowledged as contributors to residual ASCVD risk that exists in patients on statin therapy with controlled LDL-C levels. Therefore, non-HDL-C is now considered an independent risk factor or predictor for CVD. The popularity of non-HDL-C is attributed to its ease of estimation and non-dependency on fasting status. It is also better at predicting ASCVD risk in patients on statin therapy, and/or in those with obesity, diabetes, and metabolic disorders. In addition, large follow-up studies have reported that individuals with higher baseline non-HDL-C at a younger age (<45 years) were more prone to adverse CVD events at an older age, suggesting a predictive ability of non-HDL-C over the long term. Consequently, non-HDL-C is recommended as a secondary goal for dyslipidemia management by most international guidelines. Intriguingly, geographical patterns in recent epidemiological studies showed remarkably high non-HDL-C attributable mortality in high-risk countries. This review highlights the independent role of non-HDL-C in ASCVD pathogenesis and prognosis. In addition, the need for a country-specific approach to dyslipidemia management at the community/population level is discussed. Overall, non-HDL-C can become a co-primary or primary goal in dyslipidemia management., (Copyright © 2023 The Authors. Published by Elsevier B.V. All rights reserved.)

Modern biomedical research is characterised by its high-throughput and interdisciplinary nature. Multiproject and consortium-based collaborations requiring meaningful analysis of multiple heterogeneous phenotypic datasets have become the norm; however, such analysis remains a challenge in many regions across the world. An increasing number of data harmonisation efforts are being undertaken by multistudy collaborations through either prospective standardised phenotype data collection or retrospective phenotype harmonisation. In this regard, the Phenotype Harmonisation Working Group (PHWG) of the Human Heredity and Health in Africa (H3Africa) consortium aimed to facilitate phenotype standardisation by both promoting the use of existing data collection standards (hosted by PhenX), adapting existing data collection standards for appropriate use in low- and middle-income regions such as Africa, and developing novel data collection standards where relevant gaps were identified. Ultimately, the PHWG produced 11 data collection kits, consisting of 82 protocols, 38 of which were existing protocols, 17 were adapted, and 27 were novel protocols. The data collection kits will facilitate phenotype standardisation and harmonisation not only in Africa but also across the larger research community. In addition, the PHWG aims to feed back adapted and novel protocols to existing reference platforms such as PhenX., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Lyndon Zass et al.)

Background This study evaluated the comprehension and awareness of human papillomavirus (HPV) infection and vaccination among women in Jeddah, Saudi Arabia. Methods A cross-sectional study included 696 female respondents from Jeddah between the ages of 18 and 60. Ethical approval and informed consent were obtained before administering the questionnaire through social media. The data collected included social demographic information and information about HPV and vaccination. Results According to the results, only 332 respondents (47.70%) demonstrated good knowledge about HPV. Less than half (47.84%) were aware of the HPV vaccine. However, a slightly higher percentage (53.02%) would be willing to receive the vaccination if it were free. Individuals who were not willing to accept the vaccine believed it had side effects (25.70%), was unsafe (19.92%), or was unnecessary as HPV was a rare infection (17.55%). Demographic variables, such as educational level and occupation, were found to be predictors of HPV knowledge since their corresponding p-values were statistically significant. Conclusion It is crucial to raise awareness about HPV and its vaccine among adult women in Jeddah due to the alarmingly low levels of knowledge and awareness. The importance of HPV vaccination must be emphasized repeatedly to ensure that this critical information is understood and acted upon. Overall, there is low knowledge and awareness about HPV and its vaccine among adult women in Jeddah. Therefore, it is imperative to increase awareness while reiterating the importance of HPV vaccination., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Radwan et al.)

Introduction: COVID-19 is the most recent coronavirus diseases that was first identified in December 2019 and began its exponential spread globally. The critical role of nurses can be severely impacted during pandemics such as COVID-19 when the world is less prepared., Objective: To investigate and measure COVID-19 patients' satisfaction levels with the quality of nursing care provided in the Riyadh Province of Saudi Arabia., Methods: The study used a cross-sectional questionnaire to collect data from COVID-19 patients who were hospitalized or quarantined for at least 48 h or more. The study utilized the Arabic version of the Patient Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ-Ar) to assess patients' satisfaction levels with nursing care. Descriptive statistics, Mann-Whitney U, and Kruskal-Wallis tests were performed to examine the objectives of the study., Results: Ninety-six patients reported relatively high satisfaction levels with the overall nursing care. Patients also reported high satisfaction levels with the provided care, and the information that was provided. There were statistically significant differences in the mean score of patients satisfaction in relation to age, educational level, where patients are originally from, and patients recommendation of the hospitals., Conclusions: Individual characteristics and attributes played a role in the process of evaluating nursing care services. Measuring nursing care quality clarified the significant role of nurses during the COVID-19 pandemic. This study provides valuable information that could help in identifying weaknesses and reinforcing strengths about nursing care to be fully prepared against pandemics and other health-related crises and emergencies in the future., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Background and Aims: Disorders of plasma lipids remain key risk factors for the development of atherosclerotic cardiovascular disease (ASCVD) in the Middle East and are estimated to increase more dramatically in the next decade than in any other global region except Africa. This statement is an update to the 2016 consensus clinical recommendations for the management of plasma lipid disorders in the Middle East, following the evaluation of newer cholesterol-lowering agents in randomised controlled cardiovascular outcome trials, as well as the publication of revised international guidelines., Methods: A multidisciplinary panel of regional experts was convened to update the consensus clinical recommendations for the management of plasma lipids in the Middle East. The recommendations constructed in 2016 were reviewed against emerging research since publication., Results: Newly developed Middle East ASCVD risk categories were established using the multiple risk group categories from the recently updated international guidelines and the epidemiological evidence from the Gulf Region. These consensus recommendations support a more intensive reduction of LDL-C across cardiovascular risk categories. Alongside low-density lipoprotein cholesterol, we recommend non-high-density lipoprotein cholesterol as a primary treatment target. Lifestyle modifications remain the first-line treatment recommendation for all patients. The first-line pharmacological treatment in patients with dyslipidaemia is statin therapy, with a number of second-line agents available. The selection of a second lipid-lowering agent for combination therapy with statin should be based on the lipid-lowering target of the patient. Guidance is also provided on the management of underlying conditions and special populations; of particular pertinence in the region are familial hypercholesterolaemia, diabetes and metabolic dyslipidaemia. New therapies have emerged from research that found positive outcomes in reducing low-density lipoprotein cholesterol levels. The initial results of these newly researched drugs strongly indicate their inclusion as future therapies in dyslipidaemia management in the Middle East., Conclusions: These updated consensus clinical recommendations provide practicing clinicians with comprehensive, region-specific guidance to improve the detection and management of plasma lipid disorders in patients in the Middle East., (Copyright © 2021.

Background and Aims: Familial hypercholesterolemia (FH) is a common autosomal dominant disorder that can result in premature atherosclerotic cardiovascular disease (ASCVD). Limited data are available worldwide about the prevalence and management of FH. Here, we aimed to estimate the prevalence and management of patients with FH in five Arabian Gulf countries (Saudi Arabia, Oman, United Arab Emirates, Kuwait, and Bahrain)., Methods: The multicentre, multinational Gulf FH registry included adults (≥18 years old) recruited from outpatient clinics in 14 tertiary-care centres across five Arabian Gulf countries over the last five years. The Gulf FH registry had four phases: 1- screening, 2- classification based on the Dutch Lipid Clinic Network, 3- genetic testing, and 4- follow-up., Results: Among 34,366 screened patient records, 3713 patients had suspected FH (mean age: 49±15 years; 52% women) and 306 patients had definite or probable FH. Thus, the estimated FH prevalence was 0.9% (1:112). Treatments included high-intensity statin therapy (34%), ezetimibe (10%), and proprotein convertase subtilisin/kexin type 9 inhibitors (0.4%). Targets for low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol were achieved by 12% and 30%, respectively, of patients at high ASCVD risk, and by 3% and 6%, respectively, of patients at very high ASCVD risk (p <0.001; for both comparisons)., Conclusions: This snap-shot study was the first to show the high estimated prevalence of FH in the Arabian Gulf region (about 3-fold the estimated prevalence worldwide), and is a "call-to-action" for further confirmation in future population studies. The small proportions of patients that achieved target LDL-C values implied that health care policies need to implement nation-wide screening, raise FH awareness, and improve management strategies for FH., Competing Interests: The authors have read the journal’s policy and the authors of this manuscript have the following competing interests: KA reports grants from Sanofi during the conduct of the study and other funs from Sanofi, Abbott, and MSD outside the submitted work; NA reports personal fees from Sanofi, Aegerion, Merck Sharp, Abbott, AstraZeneca, Pfizer, and Amgen outside the submitted work; HS reports personal fees from Sanofi and Amgen outside the submitted work.

African genomic medicine and microbiome datasets are usually not well characterized in terms of their origin, making it difficult to find and extract data for specific African ethnic groups or even countries. The Pan-African H3Africa Bioinformatics Network (H3ABioNet) recognized the need for developing data portals for African genomic medicine and African microbiomes to address this and ran a hackathon to initiate their development. The two portals were designed and significant progress was made in their development during the hackathon. All the participants worked in a very synergistic and collaborative atmosphere in order to achieve the hackathon's goals. The participants were divided into content and technical teams and worked over a period of 6 days. In response to one of the survey questions of what the participants liked the most during the hackathon, 55% of the hackathon participants highlighted the familial and friendly atmosphere, the team work and the diversity of team members and their expertise. This paper describes the preparations for the portals hackathon and the interaction between the participants and reflects upon the lessons learned about its impact on successfully developing the two data portals as well as building scientific expertise of younger African researchers.

Following the publication of the first human genome, OMICs research, including genomics, transcriptomics, proteomics, and metagenomics, has been on the rise. OMICs studies revealed the complex genetic diversity among human populations and challenged our understandings of genotype-phenotype correlations. Africa, being the cradle of the first modern humans, is distinguished by a large genetic diversity within its populations and rich ethnolinguistic history. However, the available human OMICs tools and databases are not representative of this diversity, therefore creating significant gaps in biomedical research. African scientists, students, and publics are among the key contributors to OMICs systems science. This expert review examines the pressing issues in human OMICs research, education, and development in Africa, as seen through a lens of computational biology, public health relevant technology innovation, critically-informed science governance, and how best to harness OMICs data to benefit health and societies in Africa and beyond. We underscore the disparities between North and Sub-Saharan Africa at different levels. A harmonized African ethnolinguistic classification would help address annotation challenges associated with population diversity. Finally, building on the existing strategic research initiatives, such as the H3Africa and H3ABioNet Consortia, we highly recommend addressing large-scale multidisciplinary research challenges, strengthening research collaborations and knowledge transfer, and enhancing the ability of African researchers to influence and shape national and international research, policy, and funding agendas. This article and analysis contribute to a deeper understanding of past and current challenges in the African OMICs innovation ecosystem, while also offering foresight on future innovation trajectories.

Neck circumference (NC) is an attractive method for determining overweight and obesity in school age children because it is inexpensive and culturally acceptable. However, this technique has not been assessed for its accuracy in school children from countries of the Gulf Cooperation Council, which have high prevalence of overweight and obesity.The aim of this preliminary study was to investigate the correlation between the body mass index (BMI), NC, and waist-hip ratio and demographic characteristics among 10- to 18-year-old adolescent school children in Bahrain.BMI was calculated using Center of Disease Control and Prevention Children's BMI Tool for Schools. Data was collected for a total of n = 397 adolescents from 4 different private schools with an average age of 12.91 years; 57.7% were male and 42.3% female.In this sample of adolescents, 50.1% were either overweight (21.4%) or obese (28.7%). BMI was significantly associated with waist-hip ratio (P < .01), gender (P < .05), and age (P < .01). Multiple linear regressions revealed that NC was significantly associated with age (P < .001) and less so with gender (P = .071) and BMI was significantly associated with NC (P < .01), gender (P < .01), and age (P < .05). Analysis of the receiver operating characteristic for males and females combined showed fair sensitivity and specificity (Area under the curve (AUC) = 0.707; 95% CI: 0.656, 0.758).NC is weakly correlated with BMI, and only a fair instrument for identifying overweight/obesity based on receiver operating characteristic curve analysis. Therefore, NC could only be used as an adjunct screening tool for weight status in this sample.

Aim: To determine the prevalence, genetic characteristics, current management and outcomes of familial hypercholesterolaemia (FH) in the Gulf region., Methods: Adult (18-70 years) FH patients were recruited from 9 hospitals and centres across 5 Arabian Gulf countries. The study was divided into 4 phases and included patients from 3 different categories. In phase 1, suspected FH patients (category 1) were collected according to the lipid profile and clinical data obtained through hospital record systems. In phase 2, patients from category 2 (patients with a previous clinical diagnosis of FH) and category 1 were stratified into definitive, probable and possible FH according to the Dutch Lipid Clinic Network criteria. In phase 3, 500 patients with definitive and probable FH from categories 1 and 2 will undergo genetic testing for 4 common FH genes. In phase 4, these 500 patients with another 100 patients from category 3 (patients with previous genetic diagnosis of FH) will be followed for 1 year to evaluate clinical management and cardiovascular outcomes. The Gulf FH cohort was screened from a total of 34,366 patients attending out-patient clinics., Results: The final Gulf FH cohort consisted of 3,317 patients (mean age: 47±12 years, 54% females). The number of patients with definitive FH is 203. In this initial phase of the study, the prevalence of (probable and definite) FH is 1/232., Conclusion: The prevalence of FH in the adult population of the Arabian Gulf region is high. The Gulf FH registry, a first-of-a-kind multi-national study in the Middle East region, will help in improving underdiagnosis and undertreatment of FH in the region., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Tedizolid phosphate is approved for the treatment of acute bacterial skin and skin structure infections. To determine whether the expected dose of tedizolid phosphate can be delivered via nasogastric tube in patients who have difficulty swallowing and in whom venous access is not suitable, this in vitro study evaluated the recovery of tedizolid phosphate 200-mg tablets after crushing, dispersion in water, and passage through a nasogastric tube. To analyze the chemical stability of the crushed tablet dispersed in water, the aqueous preparation was assayed initially after dispersion and again after 4 h at room temperature. Recovery of tedizolid phosphate after the crushed tablets were dispersed in water and passed through nasogastric tubes ranged from 92.5 to 97.1 %, which is within the specified acceptance criteria of 90 to 110 %. There was no significant change in recovery values after 4 h of storage at room temperature (93.9 % initially and 94.7 % after 4 h). The stability and recovery findings support the feasibility of administering an aqueous dispersion of crushed tedizolid phosphate tablets through a nasogastric tube in patients who have difficulty swallowing and in whom intravenous administration is not possible.

Background: Medical students can play a vital role in health research at any institute. Moreover, scientific publication by medical students is a strong indicator of students' knowledge, skills and attitudes towards scientific research. Very little information exists, however, on this matter in Saudi Arabia., Subjects and Methods: This cross-sectional study was conducted to assess the publication practices of medical interns who graduated from King Abdulaziz University Faculty of Medicine and to investigate barriers to conducting and publishing research during their medical studies. A questionnaire was distributed to 394 interns and 249 (63.2%) responded., Results: About 31% of the responding interns started research during their undergraduate study years. About 12% discontinued their research, whereas only 7% submitted their research for publication. Only 3.2% of the interns had their research papers published and 3.2% had their research paper accepted for publication; 2% had research papers under revision. Interns had positive attitudes towards research, although only a few of them had submitted their papers for publication. Furthermore, interns expressed the need for training in research design, scientific paper writing and publication practice. They recommended devoting slots in medical school curriculum, in addition to other extracurricular training workshops, to teach and train students on such practices and also to provide more convenient opportunities for student participation in conferences., Conclusion and Recommendations: Interns in King Abdulaziz University Faculty of Medicine have a positive attitude towards research; however, few students submit papers for publication. Lack of time and training in research methods were the main obstacles cited by the interns for conducting and publishing research. Interns welcome training in research, scientific writing and publication practice. These requirements will be issued to the main curriculum committee at the faculty of medicine and recommendations on possible actions will be discussed with the administration.

Background: Women make up half of the world's population, and comprise 20% of the world's one billion smokers. The aim of this study was to assess the prevalence of smoking among female medical students in comparison to female non-medical students, and to assess the importance of medical education and knowledge in decreasing the prevalence of smoking among female university students in Saudi Arabia., Method: We used a self-administered questionnaire to collect cross-sectional data from a randomly selected sample of 320 female students attending King Abdul-Aziz University, Jeddah. Medical students comprised 50% of the sample., Results: A total of 310 students (96.9%) completed and returned the questionnaire. The prevalence of smoking was higher in non-medical female students (4.2%) compared to medical female students (0.32%) (P < 0.001)., Conclusion: The prevalence of smoking is low among female medical students compared to female non-medical students, presumably because of their awareness, level of education, and knowledge of the risks to health associated with smoking. Our study highlights the need for increased knowledge, health education, and awareness of the risks of smoking to reduce smoking among female university students.

Serum concentrations of total cholesterol, triglycerides, and apolipoproteins (apo) A-I, B, CII, CIII, and E in 36 hemodialysis patients and nine anephric patients were compared with the concentrations in 34 normolipidemic subjects. The dialysis patients displayed a moderate hypertriglyceridemia (1.94 +/- 0.12 vs 1.09 +/- 0.11 mmol/L in controls, mean +/- SEM; P less than 0.001), apo CIII concentrations were also increased (130.2 +/- 2.1 vs 108.4 +/- 0.7 mg/L; P less than 0.001), whereas apo CII (34.5 +/- 0.5 vs 36 +/- 0.5 mg/L; P less than 0.05), apo E (22.7 +/- 0.3 vs 27.9 +/- 0.2 mg/L; P less than 0.001), and apo A-I (1.18 +/- 0.05 vs 1.31 +/- 0.04 g/L; P less than 0.05) were decreased. Concentrations of serum apo B were normal (0.86 +/- 0.03 vs 0.97 +/- 0.07 g/L). In the hemodialysis patients, apo CIII concentrations were increased in apo B-containing lipoproteins (30.1 +/- 0.5 vs 25.0 +/- 0.1 mg/L; P less than 0.001), whereas CII and E were decreased below control values (14.4 +/- 0.2 vs 16.8 +/- 0.1, and 8.2 +/- 0.2 vs 11.4 +/- 0.1 mg/L, respectively; P less than 0.001 each). By calculation, non-B-containing lipoproteins in the hemodialysis group had increased concentrations of apo CIII (100.1 +/- 2.1 vs 83.3 +/- 0.7 mg/L; P less than 0.001) and decreased amounts of apo E (14.5 +/- 0.4 vs 16.4 +/- 0.3 mg/L; P less than 0.001); apo CII content was unchanged (20.1 +/- 0.5 vs 19.3 +/- 0.5 mg/L). Results for apo CII, CIII, and E among apo A-I-containing lipoproteins in both normolipidemic and hemodialysis groups were similar to those in non-B-containing lipoproteins. Finally, the sole significant (P less than 0.01) difference between the anephric and hemodialysis groups was the lower apo E concentrations in the former group. Accumulation of triglyceride-rich lipoproteins in hemodialysis patients may thus be related to the enrichment of apo CIII in apo B-containing lipoproteins and to a marked decrease in the apo CII and E contents.
