ABSTRACT

Blood transfusion is a critical life-saving medical intervention, but it carries the risk of transfusion-transmitted infections (TTIs) that can lead to serious consequences. TTIs include viral, bacterial, parasitic, and prion infections, transmitted through asymptomatic donor blood, contamination of stored blood products, or transfusion-related immunosuppression. Recognized global agents posing challenges to blood safety include human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), Syphilis, etc. Emerging pathogens like SARS-CoV-2, hepatitis E, and others present additional risks. The residual risk of TTIs, representing the likelihood of infected donations passing screening tests, varies globally. High-income countries generally show lower prevalence rates than low-income countries. In Egypt, the estimated prevalence rates for HIV, HBV, HCV, and syphilis markers among the donors are 0.23 %, 0.76 %, 2.33 %, and 0.24 %, respectively. In Egypt, specific residual risk estimates are scarce, but prevalence rates for key infections highlight existing challenges. The World Health Organization promotes a global blood safety strategy, advocating for national blood systems, voluntary non-remunerated donors, and quality-assured testing. Despite these measures, the establishment of a haemovigilance system which is critical for monitoring and preventing adverse events, including TTIs, is reported as lacking in Egypt. This highlights the importance of comprehensive surveillance and safety measures in the blood donation process to ensure universal access to safe blood. Primary health care can play a pivotal role in preventing TTIs.

ABSTRACT

INTRODUCTION: Management of obesity is challenging for both patients and healthcare workers. Considering the low success rate of current interventions, this study aimed to explore the prevalence and associated factors of night eating syndrome (NES), insomnia, and psychological distress among individuals with obesity in order to plan comprehensive obesity management interventions. METHODS: A cross-sectional study on a convenient sample from five primary healthcare centers in Port Said, Egypt, was conducted from November 2020 to March 2021. Sociodemographic and clinical characteristics were collected in addition to the assessment of NES, insomnia, and psychological distress using the Arabic versions of the Night Eating Diagnostic Questionnaire (NEQ), the Insomnia Severity Index (ISI), and the Patient Health Questionnaire-4 (PHQ-4) scales, respectively. Associations of NES, insomnia, and psychological distress were assessed by multiple regression analysis. We performed Bonferroni adjustments for multiple comparisons. RESULTS: We included 425 participants with obesity with a mean age of 45.52 ± 6.96 years. In all, 54.4% were females and the mean body mass index (BMI) was 35.20 ± 4.41 kg/m2. The prevalence rates of NES, insomnia, and psychological distress were 21.6% (95% CI: 17.7-25.6%), 15.3% (95% CI: 11.9-18.7%), and 18.8% (95% CI: 15.1-22.6%), respectively. NES was significantly associated with younger age (OR 0.974, p = 0.016), physical inactivity (OR 0.485, p = 0.010), insomnia (OR 2.227, p = 0.014), and psychological distress (OR 2.503, p = 0.002). Insomnia showed strong associations with NES (OR 2.255, p = 0.015) and psychological distress (OR 5.990, p < 0.001). Associated factors of psychological distress symptoms included insomnia (OR 6.098, p < 0.001) and NES (OR 2.463, p = 0.003). CONCLUSION: The prevalence rates of NES, insomnia, and psychological distress were high among primary care patients with obesity, and these conditions were interrelated. Optimal obesity management necessitates individualized and targeted multidisciplinary care plans that take into consideration individual patients' mental, behavioral, and dietary habits needs.

ABSTRACT

BACKGROUND: Health coaching effectively improves hypertension self-care activities and the control of blood pressure (BP) in hypertensive patients. Studies on the effects of health coaching on patients in primary care with uncontrolled hypertension in developing countries are limited. In this study, the effectiveness of health coaching on hypertension self-care and BP control was assessed in patients who have uncontrolled hypertension compared to standard care in Egypt. MATERIALS AND METHODS: Our quasi-experimental study included control and intervention groups. The intervention group included 70 participants who received health coaching sessions (face-to-face and by telephone) besides the standard care, whereas the control group included 71 participants who only received the standard care. The study was conducted between July 2020 and November 2021. The participants were recruited from three primary healthcare settings in the Port Said Governorate. Personal and medical history, BP measurements, and hypertension self-care activity level effects (H-SCALE) were obtained. Paired-t-test was used to assess the changes in BP measurement, and H-SCALE score before and after receiving the health coaching. McNemar's test was used to assess changes in controlled BP and optimal hypertension self-care activities between control and health coached groups. Multiple logistic regression analysis assessed the predictors of better BP control. RESULTS: Health coaching resulted in more controlled BP (51.4%, P < 0.001) compared to the delivery of only usual care (11.3%, P = 0.008). The intervention showed a significant promotion in hypertension self-care activities, including medication usage (P < 0.001), low-salt diet (P < 0.001), and weight management (P < 0.001). The H-SCALE score mean change was the only predictor for BP control (odds ratio 1.057, P = 0.048) in the intervention group after 6 months. CONCLUSION: Intervention including traditional health coaching and phone calls is a beneficial modality for the promotion of hypertension self-care and improvement of BP control in primary care patients with uncontrolled hypertension.

ABSTRACT

Objectives: To evaluate the association of diabetes treatment satisfaction and trust in family physicians with glycemic control among primary care patients with type 2 diabetes mellitus. Methods: A cross-sectional study on 319 patients with type 2 diabetes mellitus from five primary healthcare centers in Egypt. Data were collected from February to August 2021 using a structured questionnaire that contained six parts: sociodemographic data, disease profile, the Diabetes Treatment Satisfaction Questionnaire (DTSQ), 8-item Morisky Medication Adherence Scale (MMAS-8), self-reported medication knowledge questionnaire (MKQ), and revised healthcare relationship trust scale (HCR). Multiple linear regression analysis was used to assess predictors of treatment satisfaction, physician trust, and HbA1c level. P values less than 0.05 were considered significant. Results: The mean age was 59.66 years (± 7.87 years) and 55.17% were females. Multiple linear regression analysis for predicting HbA1c showed that HbA1c level was lower in patients with higher treatment satisfaction scores (ß = - 0.289, p < 0.001) and higher medication adherence scores (ß = - 0.198, p = 0.001). Treatment satisfaction scores were positively predicted by higher physician trust scores (ß = 0.301, p < 0.001), increased medication adherence scores (ß = 0.160, p = 0.002), and longer duration of diabetes (ß = 0.226, p < 0.001). Positive predictors for physician trust included HbA1c level (ß = 0.141, p = 0.012), medication knowledge (ß = 0.280, p < 0.001), diabetes treatment satisfaction (ß = 0.366, p < 0.001) and medication adherence (ß = 0.146, p = 0.011). Conclusion: Optimizing diabetes treatment satisfaction and physician trust could have favorable associations with medication adherence and medication knowledge with a possible improvement in glycemic control. Family physicians should incorporate patients reported outcomes alongside traditional clinical measures in evaluating diabetes management in primary care.

ABSTRACT

BACKGROUND: Diabetes-related distress and glycemic control are of a particular concern to primary care physicians because of the impact of the coronavirus disease 2019 pandemic on diabetic patients' lifestyle, psychological well-being and healthcare access. Our aim was to evaluate the relationship between diabetes-related distress and glycemic control in diabetic patients with Type 2 diabetes mellitus (T2DM) in primary care settings during the pandemic. MATERIALS AND METHODS: This cross-sectional study was conducted at primary healthcare clinics in a rural area in Egypt among 430 patients with T2DM during the period from September 2020 to June 2021. All patients were interviewed for their sociodemographic, lifestyle, and clinical characteristics. Diabetes-related distress was measured by the problem areas in the diabetes scale (PAID), where a total score of ≥40 indicated a severe diabetes-related distress. The most recent glycosylated hemoglobin (HbA1c) measurements were used to indicate the glycemic control. Quantile regression model (0.50 quantile) was used to perform the multivariate analysis to identify significant factors associated with HbA1c level. RESULTS: Most of the participants had a suboptimal glycemic control (92.3%), while 13.3% had severe diabetes-related distress. HbA1c level was significantly and positively correlated with the total PAID score and all its sub-domains. Multivariate quantile regression revealed that obesity, multi-morbidity, and severe diabetes-related distress were the only significant determinants of the HbA1c median level. Obese patients had significantly higher median HbA1c compared to patients who were not obese (coefficient = 0.25, P < 0.001). Patients with two or more comorbidities (i.e., multimorbidity) had a significantly higher median HbA1c than patients with single or no chronic comorbidities (coefficient = 0.41, P < 0.001). Severe diabetes-related distress was significantly associated with higher median HbA1c compared to nonsevere diabetes-related distress (coefficient = 0.20, P = 0.018). CONCLUSION: Diabetes-related distress had a significant association with HbA1c level. Family physicians should implement multifaceted programs to optimize diabetes control and reduce any associated distress.

ABSTRACT

Objective: Egyptian studies in assessing the relationship between diabetes self-care, social support, and glycemic control in primary healthcare (PHC) are limited. Therefore, this study aimed to assess this relationship, and to evaluate the associated factors of diabetes self-care, social support, and glycemic control in Egyptian PHC patients with type 2 diabetes (T2DM). Methods: A cross-sectional study was conducted on 320 T2DM patients at four PHC settings in Port Said city, affiliated with the General Authority of Healthcare. A semi-structured questionnaire was used to collect data, including demographic characteristics, socioeconomic status scale, disease profile, the Arabic versions of the Summary of Diabetes Self-Care Activities, and the received social support scales. Data were collected from January 2020 to June 2020. Results: Diabetes self-care activities, and self-monitoring of blood glucose had a very weak negative correlations with glycated hemoglobin (HbA1c) levels (rho = - 0.125, p = 0.025, rho = - 0.112, p = 0.044, respectively). Receiving social support on following a meal correlated positively and very weakly with HbA1c levels (rho = 0.145, p = 0.010). Hardly positive correlation was found between receiving emotional support on feelings about diabetes, and following a specific diet (rho = 0.169, p = 0.002). Diabetes self-care activities were positively associated with higher education levels, and elevated BMI. Received social support was negatively associated with having coronary artery disease, and marital status e.g. divorced and widow. Increased age, and female gender were the predictors of good glycemic control. Conclusion: Diabetes self-care activities were linked with reduced HBA1c levels. Further studies are needed to evaluate the buffering effect of social support on glycemic outcomes in PHC patients with T2DM.

ABSTRACT

Aims: Despite the availability of a wide selection of antidiabetic treatments, many patients with type 2 diabetes mellitus (T2DM) still do not have controlled glucose levels. This study aimed to assess illness perception, medication adherence, and glycemic control among primary care attendees with T2DM. Methods: A cross-sectional study was conducted between July 2019 and November 2020. A random sample of 265 Egyptian T2DM patients were enrolled from primary health-care settings in Port Said, Egypt. Data on socio-demographic characteristics, lifestyle habits, and diabetic medical history were collected using a semi-structured questionnaire. The Brief Illness Perception Questionnaire (B-IPQ) was used to assess diabetes perception, whereas the 8-item Morisky Medication Adherence Scale (MMAS-8) was used to investigate medication adherence. Results: There was a significant difference in B-IPQ scores between different groups of the patients in terms of diabetic medications, complications, and glycemic control (p < 0.05). There was a significant difference in MMAS-8 score found between different groups of the patients in terms of disease duration, family history of T2DM, and glycemic control (p < 0.05). Further, there was a significant difference in HbA1c score found between different groups of patients in terms of disease duration, medications, complications, and family history of T2DM (p < 0.05). Higher BMI, a positive family history of T2DM, patients who take insulin, high illness perception, and poor medication adherence were the factors associated with higher HbA1c level. Conclusion: Higher HbA1c levels were linked to a higher BMI, a positive family history of T2DM, insulin users, high illness perception, and poor medication adherence.

ABSTRACT

BACKGROUND: Screening for diabetes distress is recommended when caring for patients with type 2 diabetes mellitus (T2DM) in primary healthcare (PHC). The 5-item Problem Areas in Diabetes (PAID-5) scale is widely used to measure diabetes distress, but its Arabic validation studies are scarce, so this study was carried to assess the psychometric properties of the Arabic version of the PAID-5 (AR-PAID-5) in Egyptian PHC patients with T2DM. METHODS: We conducted a cross-sectional study including 260 participants from six rural PHC settings in Ismailia governorate, Egypt. Internal consistency using Cronbach's α and one-month test-retest reliability using intraclass correlation coefficient (ICC) were investigated. Confirmatory factor analysis (CFA) was used to evaluate the one-factor structure of the AR-PAID-5. Correlations of the AR-PAID-5 with the Arabic versions of the 20-item Problem Areas in Diabetes (PAID), Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), 5-item World Health Organization Well-Being Index (WHO-5) scales and glycated hemoglobin (HbA1c) were investigated for supporting the convergent validity. Associations of the PAID-5 with sociodemographic, and clinical characteristics were assessed for demonstrating the discriminant validity. Criterion validity was also evaluated. RESULTS: There was a good internal consistency (α = 0.88) and a stable test-retest reliability (ICC = 0.74). The CFA confirmed the one-factor structure of the AR-PAID-5. Significant positive correlations existed between the AR-PAID-5 with diabetes distress evaluated by the Arabic version of the PAID (rho = 0.93, p < 0.001), depressive symptoms (PHQ-9) (rho = 0.56, p < 0.001), anxiety symptoms (GAD-7) (rho = 0.47, p < 0.001), emotional well-being (WHO-5) (rho = - 0.38, p < 0.001), and HbA1c (rho = 0.16, p = 0.003). A satisfactory discriminant validity, and an acceptable criterion validity were demonstrated. CONCLUSIONS: The AR-PAID-5 scale is a reliable and valid tool that can be used for diabetes distress screening and in research in Arabic speaking PHC patients with T2DM.

ABSTRACT

The prevalence of type 2 diabetes mellitus (T2DM) is growing worldwide. T2DM is often complicated by a range of psychological disorders that interfere with glycemic control and self-care. Previous studies have reported diabetes distress, depression, and anxiety among patients with T2DM; however; little is known about the burden of these comorbid mental disorders in primary care patients with T2DM treated in Egypt during the COVID-19 era. Participants were selected by convenient sampling from eight rural primary healthcare facilities from Ismailia in Egypt. Symptoms of diabetes distress, depression and anxiety were assessed by using the Arabic version of the 20-item Problem Areas in Diabetes (PAID), Patient Health Questionnaire 9, and Generalized Anxiety Disorder Scales, respectively. Multiple hierarchical logistic regression models were used to estimate the significant factors associated with diabetes distress, depression, and anxiety. A total of 403 individuals with T2DM were interviewed. The prevalence of severe diabetes distress was 13.4% (95% CI: 10.1-16.7), while prevalence of depressive and anxiety symptoms was 9.2% (95% CI: 6.4-12.0%), and 4.0% (95% CI: 2.1-5.9), respectively. In a series of hierarchical logistic regression models, significant predictors for diabetes distress were being married, illiterate, not-working, living with insufficient income, and having multi-comorbidities. Likewise, the significant predictors for depression and anxiety were elevated glycated hemoglobin level and the higher PAID total score, while having multi-comorbidities was a significant predictor for anxiety only. Diabetes distress was more prevalent than depressive and anxiety symptoms in this study population. Several sociodemographic and clinical characteristics were identified to be related with psychological problems among patients with T2DM, which necessitate a multidisciplinary team-based approach for optimal screening and management.

ABSTRACT

Background: The Problem Areas in Diabetes (PAID) scale is a reliable and valid tool that is widely used for diabetes-distress screening, but the Arabic version of the scale lacks validity and reliability analysis in primary healthcare (PHC) patients. Our study aimed to evaluate the psychometric properties of the Arabic version of the PAID (AR-PAID) scale among Egyptian patients with type 2 diabetes mellitus (T2DM) in PHC settings. Methods: We conducted a cross-sectional study on a convenience sample of 200 patients from six rural PHC settings in the Ismailia governorate. The confirmatory factor analysis (CFA) was performed to test the goodness-of-fit to the predefined models of the PAID. Convergent construct was evaluated through correlations with the Arabic versions of the Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and 5-item World Health Organization Well-Being Index (WHO-5), additionally glycated hemoglobin (HbA1c) levels. Discriminant validity was evaluated through associations with patients' sociodemographic and clinical characteristics. Reliability was evaluated through internal consistency (Cronbach's α) and test-retest reliability analysis (intraclass correlation coefficient, ICC). Results: The CFA demonstrated the best fit for a four-factor model. The AR-PAID was significantly correlated with the following measures: PHQ-9 (rho = 0.71, p < 0.001), GAD-7 (rho = 0.50, p < 0.001), WHO-5 (rho = -0.69, p < 0.001), and HbA1c (rho = 0.36, p < 0.001), supporting sound convergent validity. Discriminant validity was satisfactory demonstrated. Internal consistency was excellent (α = 0.96) and test-retest reliability was stable (ICC = 0.97). Conclusions: The AR-PAID scale is a valid and reliable instrument for diabetes-distress screening in primary care patients with T2DM that can be used in clinical settings and research. Further research is needed to validate short forms of the AR-PAID scale.

ABSTRACT

BACKGROUND AND OBJECTIVE: Low-dose acetylsalicylic acid (ASA, aspirin) is a well-known and frequently studied drug for primary and secondary prevention of disease due to its anti-inflammatory and coagulopathic effects. COVID-19 complications are attributed to the role of thrombo-inflammation. Studies regarding the use of low-dose ASA in COVID-19 are limited. For this reason, we propose that the use of low-dose ASA may have protective effects in COVID-19-related thromboembolism and lung injury. This study was conducted to assess the efficacy of low-dose ASA compared with enoxaparin, an anticoagulant, for the prevention of thrombosis and mechanical ventilation. METHODS: We conducted a retrospective cohort study on COVID-19-confirmed hospitalized patients at the Mansoura University Quarantine Hospital, outpatients, and home-isolated patients from September to December 2020 in Mansoura governorate, Egypt. Binary logistic regression analysis was used to assess the effect of ASA compared with enoxaparin on thromboembolism, and mechanical ventilation needs. RESULTS: This study included 225 COVID-19 patients. Use of ASA-only (81-162 mg orally daily) was significantly associated with reduced thromboembolism (OR 0.163, p = 0.020), but both low-dose ASA and enoxaparin, and enoxaparin-only (0.5 mg/kg subcutaneously (SC) daily as prophylactic dose or 1 mg/kg SC every 12 hours as therapeutic dose) were more protective (odds ratio [OR] 0.010, OR 0.071, respectively, p < 0.001). Neither ASA-only nor enoxaparin-only were associated with a reduction in mechanical ventilation needs. Concomitant use of low-dose ASA and enoxaparin was associated with reduced mechanical ventilation (OR 0.032, 95% CI 0.004-0.226, p = 0.001). CONCLUSIONS: Low-dose ASA-only use may reduce the incidence of COVID-19-associated thromboembolism, but the reduction may be less than that of enoxaparin-only, and both ASA and enoxaparin. Concomitant use of ASA and enoxaparin demonstrates promising results with regard to the reduction of thrombotic events, and mechanical ventilation needs.

ABSTRACT

OBJECTIVES: To review the pathophysiology of COVID-19 disease, potential aspirin targets on this pathogenesis and the potential role of aspirin in patients with COVID-19. DESIGN: Narrative review. SETTING: The online databases PubMed, OVID Medline and Cochrane Library were searched using relevant headlines from 1 January 2016 to 1 January 2021. International guidelines from relevant societies, journals and forums were also assessed for relevance. PARTICIPANTS: Not applicable. RESULTS: A review of the selected literature revealed that clinical deterioration in COVID-19 is attributed to the interplay between endothelial dysfunction, coagulopathy and dysregulated inflammation. Aspirin has anti-inflammatory effects, antiplatelet aggregation, anticoagulant properties as well as pleiotropic effects on endothelial function. During the COVID-19 pandemic, low-dose aspirin is used effectively in secondary prevention of atherosclerotic cardiovascular disease, prevention of venous thromboembolism after total hip or knee replacement, prevention of pre-eclampsia and postdischarge treatment for multisystem inflammatory syndrome in children. Prehospital low-dose aspirin therapy may reduce the risk of intensive care unit admission and mechanical ventilation in hospitalised patients with COVID-19, whereas aspirin association with mortality is still debatable. CONCLUSION: The authors recommend a low-dose aspirin regimen for primary prevention of arterial thromboembolism in patients aged 40-70 years who are at high atherosclerotic cardiovascular disease risk, or an intermediate risk with a risk-enhancer and have a low risk of bleeding. Aspirin's protective roles in COVID-19 associated with acute lung injury, vascular thrombosis without previous cardiovascular disease and mortality need further randomised controlled trials to establish causal conclusions.

ABSTRACT

BACKGROUND: MicroRNA (miRNAs) are small non-coding molecules that play an important role in hepatitis C virus (HCV) replication and liver diseases progression. The current study aimed to evaluate serum miRNAs as potential biomarkers for diagnosis, monitoring of fibrosis progression and prediction of responses to direct-acting antivirals (sofosbuvir + daclatasvir + ribavirin) in HCV genotype-4 patients. METHODS: The serum levels of four miRNAs (miRNA-21, 199, 448 and 181c) were assessed in 150 HCV patients and 50 healthy controls using quantitative real-time PCR. The diagnostic accuracy was determined using receiver operating characteristic (ROC) curve. RESULTS: The four studied miRNAs showed significant upregulation in HCV patients compared with controls. There were significant upregulation of MiR-199 and significant downregulation of miR-448 in late stages of fibrosis with high diagnostic accuracy (area under the curve "AUC" = 0.989%; P < .001) and (AUC = 0.0.672; P > .001), respectively. Regarding response to treatment, only miR-199 showed a significant upregulation in non-responder patients with high diagnostic accuracy (AUC = 0.968; P < .001). CONCLUSION: miR-199 and miR-448 could serve as valuable non-invasive biomarkers for assessment of liver fibrosis progression. Additionally, miR-199 could be also a potential biomarker for assessment of treatment efficacy among HCV patients. Therefore, miR-199 and miR-448 serum levels should be considered during the treatment of HCV genotype-4 patients in Egypt and the world.

ABSTRACT

INTRODUCTION: Typhoid fever is endemic in Egypt; and quinolones are the empirical treatment of choice. There are very limited data reporting quinolone resistance among Egyptian typhoidal Salmonella isolates. We previously reported that all typhoidal Salmonella were sensitive to quinolones. This study aimed to isolate and identify typhoidal Salmonella from cases suffering from enteric fever at Minia Governorate, Egypt, determine their quinolone resistance patterns, compare them to those reported 20 years ago, and test gyrA mutation as a possible mechanism for quinolone resistance. METHODOLOGY: Stool samples from Widal-positive subjects were screened by culture on suitable media and were identified biochemically. The identified isolates were tested for resistance against three representatives of the first three quinolone generations, namely nalidixic acid (NAL), levofloxacin (LEV), and norfloxacin (NOR). The gyrA gene was amplified and sequenced to detect point mutation(s) conferring quinolone resistance. RESULTS: Out of 230 stool samples (from patients with Widal anti-O titers of ≥ 1/160), 40 isolates were S. enterica serovar Typhi (97.5%) and Paratyphi A (2.5%). Six (15%) isolates were resistant to at least one of the quinolones, compared to 0% in 1993. In this regard, 15%, 7.5%, and 2.5% of the isolates were resistant to NAL, both NAL and LEV, and all three quinolones tested, respectively. Sequencing of the gyrA gene revealed point mutations at position 83 and/or 87 of the gyrA gene only among the resistant isolates. CONCLUSION: There has been an increase in quinolone-resistant typhoidal Salmonella in Egypt over time.
