Electronic Health Records (EHR) have been adopted to improve the quality of care. Despite the growing use of health information technology, nursing documentation remains a challenge. In Tunisia, the implementation of the Electronic Medical Record (EMR) system is gaining momentum as part of national initiatives to modernize healthcare. However, nursing documentation is still largely paper-based, and no studies in Tunisia have adressed this topic. This research aims to assess the effect of the Electronic Nursing Record (ENR) on the quality and safety of care indicators (QSCI). This is an interventional study structured in four phases: development, pre-implementation, implementation, and evaluation, integrating the principles of the 'Standards for Reporting Implementation Studies' (StaRI). A list of QSCI was defined and validated through a literature review and Delphi consensus. The impact of the ENR on these indicators was evaluated in a Tunisian university hospital through a quasi-experimental study. Indicators were measured before ENR, one month after, and six months after. Data analyses was conducted using SPSS with statistical tests. Initially, the study led to the identification and validation of seventeen QSCI. Subsequently, a quasi-experimental study was conducted to evaluate the impact of ENR implementation on these indicators. The results revealed a significant improvement in the intervention group (using ENR), particularly in the traceability of vital signs (p < 10⁻3) and infusion administration (p = 0.027). Conversely, the control group (using paper-based documentation) performed better in terms of traceability of inter-team handovers (95.1% compared to 71.9% for the intervention group). The electronic documentation system is seen as a major transformation in healthcare in many hospitals worldwide. Moreover, electronic nursing documentation is crucial for patient safety. Its implementation in our hospital revealed a positive impact of the ENR on certain aspects of care quality while highlighting gaps in inter-team handovers.

This study aimed to describe the molecular epidemiology and seasonality of human rhinovirus (HRV) in chronic obstructive pulmonary disease (COPD) and its association with COPD exacerbations in Abu Dhabi, the United Arab Emirates (UAE). Sputum specimens were collected for analysis from all COPD patients who visited a medical center from November 2021 to October 2022. The real-time quantitative polymerase chain reaction (qPCR) test was used to detect HRV. Of the 78 COPD patients included in the study, 58 (74%) patients presented with one or more exacerbation episodes. The incidence of COPD exacerbation peaked over the winter and substantially decreased during the summer. HRV positivity in patients during exacerbation (E1) was 11/58 (19%) and 15/58 (26%) two weeks after the exacerbation episode (E2). There was no significant difference in the HRV load in these patients. No statistically significant difference was observed in the detection of HRV during exacerbation compared to patients with stable COPD. This is the first study to assess the association between HRV detection by qPCR and COPD exacerbations in the UAE. The high sensitivity of the detection technology helped collect reliable epidemiologic data. Few studies have provided similar Middle East data. This study's pattern of COPD exacerbations and HRV detection parallels that of temperate countries. This information can help with future, more extensive surveillance of respiratory viruses in the UAE and the Middle East and their association with COPD exacerbations.

The diagnosis of acute lymphoblastic leukemia (ALL), which is the most common type of cancer in children, has become more accurate with the use of flow cytometry. Here, this technology was used to immunophenotype leukemic cells in peripheral blood samples from Libyan pediatric ALL patients. We recruited 152 newly diagnosed patients at Tripoli Medical Center (Tripoli, Libya) by morphological examination of blood and bone marrow. Twenty-three surface and cytoplasmic antigen markers were used to characterize B and T cells in circulating blood cells by four-color flow cytometry. Six children (3.9%) turned out to have biphenotypic acute leukemia, 88 (57.9%) had B ALL, and 58 (38.1%) had T ALL. There were 68 cases of pro-B ALL CD10-positive (44.7%), 8 cases of pro-B ALL CD10-negative (5.2%), 6 cases of pre-B ALL (3.9%), and 6 of mature-B ALL (3.9%). CD13 was the most commonly expressed myeloid antigen in ALL. We present immunophenotypic data for the first time describing ALL cases in Libya. The reported results indicate that the most common subtype was pro-B ALL, and the frequency of T-ALL subtype was higher compared to previous studies. Six cases were positive for both myeloid and B lymphoid markers. Our findings may provide the basis for future studies to correlate immunophenotypic profile and genetic characteristics with treatment response among ALL patients.
急性淋巴细胞白血病(ALL)是儿童最常见的癌症类型,随着流式细胞术的使用,该病的诊断变得更加准确。在这里,我们使用这种技术对利比亚儿童急性淋巴细胞白血病患者外周血样本中的白血病细胞进行免疫分型。我们在的黎波里医疗中心(利比亚的黎波里)通过血液和骨髓形态学检查招募了 152 名新确诊患者。通过四色流式细胞术对循环血细胞中的B细胞和T细胞进行了表层和胞质抗原标记。结果显示,6名儿童(3.9%)患有双型急性白血病,88名儿童(57.9%)患有B ALL,58名儿童(38.1%)患有T ALL。68例前B ALL CD10阳性(44.7%),8例前B ALL CD10阴性(5.2%),6例前B ALL(3.9%),6例成熟B ALL(3.9%)。CD13是ALL中最常表达的骨髓抗原。我们首次提供了利比亚ALL病例的免疫表型数据。报告结果表明,最常见的亚型是原B ALL,与以往的研究相比,T-ALL亚型的发生率较高。有六个病例的骨髓和B淋巴标志物均呈阳性。我们的研究结果可为今后研究ALL患者的免疫表型特征和遗传特征与治疗反应的相关性提供依据。

The ratio of fibrinogen to albumin (FAR) is considered a new inflammatory biomarker and a predictor of cardiovascular disease risk. However, its prognostic value for patients with chronic heart failure (CHF) with different ejection fractions (EFs) remains unclear. A total of 916 hospitalized patients with CHF from January 2017 to October 2021 in the First Affiliated Hospital of Kunming Medical University were included in the study. Death occurred in 417 (45.5%) patients out of 916 patients during a median follow-up time of 750 days. Among these patients, 381 patients suffered from HFrEF (LVEF <40%) and 535 patients suffered from HFpEF or HFmrEF (HFpEF plus HFmrEF, LVEF ≥ 40%). Patients were categorized into high-level FAR (FAR-H) and low-level FAR (FAR-L) groups based on the optimal cut-off value of FAR (9.06) obtained from receiver operating characteristic (ROC) curve analysis. Upon analysing the Kaplan - Meier plots, the incidence of death was significantly higher in all patients with FAR-H and patients in both HF subgroups (p < 0.001). The multivariate Cox proportional hazard analyses indicated that the FAR was an independent predictor of all-cause mortality, regardless of heart failure subtype. (HR 1.115, 95% CI 1.089-1.142, p < 0.001; HFpEF plus HFmrEF, HR 1.109, 95% CI 1.074-1.146, p < 0.0001; HFrEF, HR 1.138, 95% CI 1.094-1.183, p < 0.0001) The optimal cut-off value of FAR in predicting all-cause mortality was 9.06 with an area under the curve value of 0.720 (95% CI: 0.687-0.753, p < 0.001), a sensitivity of 68.8% and a specificity of 65.6%. After adjusting for the traditional indicators (LVEF, Lg BNP, etc.), the new model with the FAR had better prediction ability in patients with CHF. Elevated FAR is an independent predictor of death in CHF and is not related to the HF subtype.

To determine the molecular basis, genotype - phenotype relationship, and genetic origin of Hemoglobin (Hb) Hekinan associated with several forms of α-thalassemia and other hemoglobinopathies for a better understanding of its diverse clinical phenotypes. Seventeen participants with suspected abnormal Hb were studied. Hb analysis was performed using high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE). Mutational and α-haplotypic and structural analyses were conducted, and the effects of mutations on globin-chain stability were determined. All participants harbored Hb Hekinan II (HBA1:c.84 G>T) co-inherited with another α-globin gene anomaly. Three novel genotypes, (ααHekinan/αCSα), (ααHekinan/αCSα,βA/βE), and (ααHekinan/αCSα,βE/βE), were characterized. Despite being co-inherited with both α- and β-Hb variants Hb Hekinan II led to minimal changes in erythrocyte parameters, suggesting a non-pathological nature. HPLC but not CE revealed a distinct small shoulder-like Hb pattern. Thai Hb Hekinan II was strongly associated with haplotype [+ - S + - - -] and the possibility of four different haplotypes, while two Burmese Hb Hekinan II were associated with haplotypes [± - S + - + -] and [± - S + - - -]. The novel genotypes identified provide a fresh perspective on Hb Hekinan II diversity. HPLC has superior identification capabilities for samples of Hb Hekinan II co-inherited with α-thalassemia. Thai and Burmese Hb Hekinan II have diverse origins.
确定与几种形式的α-地中海贫血和其他血红蛋白病相关的血红蛋白(Hb)Hekinan 的分子基础、基因型-表型关系和遗传起源,以便更好地了解其不同的临床表型。我们对 17 名疑似血红蛋白异常的参与者进行了研究。使用高效液相色谱法(HPLC)和毛细管电泳法(CE)进行了血红蛋白分析。进行了突变、α-合型和结构分析,并确定了突变对球蛋白链稳定性的影响。所有参与者都患有与另一种α-球蛋白基因异常共同遗传的Hb Hekinan II(HBA1:c.84 G>T)。研究发现了三种新的基因型:(ααHekinan/αCSα)、(ααHekinan/αCSα,βA/βE)和(ααHekinan/αCSα,βE/βE)。尽管 Hb Hekinan II 与 α-Hb 和 β-Hb 变体共同遗传,但它导致的红细胞参数变化极小,这表明它不具有病理学性质。HPLC 而非 CE 显示了明显的小肩状 Hb 模式。泰国人的 Hb Hekinan II 与单倍型[+ - S + - -]密切相关,可能存在四种不同的单倍型,而缅甸人的两种 Hb Hekinan II 则与单倍型[± - S + - + -]和[± - S + - -]相关。新发现的基因型为 Hb Hekinan II 的多样性提供了新的视角。高效液相色谱法(HPLC)对与α-地中海贫血共同遗传的 Hb Hekinan II 样品具有卓越的鉴定能力。泰国和缅甸的 Hb Hekinan II 具有不同的来源。

This study aimed to assess the kinetics of antibodies against the SARS-CoV-2, following natural infection in a cohort of employees of the Institut Pasteur de Tunis (IPT) and to assess the risk of reinfection over a 12-months follow-up period. A prospective study was conducted among an open cohort of IPT employees with confirmed SARS-CoV-2 infection that were recruited between September 2020 and March 2021. Sera samples were taken at 1, 3, 6, 9 and 12 months after confirmation of COVID-19 infection and tested for SARS-CoV-2-specific immunoglobulin G (IgG) antibodies to the spike (S-RBD) protein (IgG anti-S-RBD) and for neutralizing antibodies. Participants who had an initial decline of IgG anti-S-RBD and neutralizing antibodies followed by a subsequent rise in antibody titers as well as those who tested positive for SARS-CoV-2 by RT-PCR after at least 60 days of follow up were considered as reinfected. In total, 137 individuals were included with a mean age of 44.7 ± 12.3 years and a sex-ratio (Male/Female) of 0.33. Nearly all participants (92.7%) were symptomatic, and 2.2% required hospitalization. Among the 70 participants with three or more prospective blood samples, 32.8% were reinfected among whom 11 (47.8%) reported COVID-19 like symptoms. Up to 12 months of follow up, 100% and 42.9% of participants had detectable IgG anti-S-RBD and neutralizing antibodies, respectively. This study showed that humoral immune response following COVID-19 infection may persist up to 12 months after infection despite the potential risk for reinfection that is mainly explained by the emergence of new variants.

Introduction: Biomarkers that could reliably anticipate the effectiveness of antihistamines and omalizumab in treating chronic spontaneous urticaria (CSU) have not been conclusively identified. Our objective was to examine how eosinophilic cationic protein (ECP), tryptase, D-dimer, and total Immunoglobulin E (IgE) impact the response to antihistamine and omalizumab treatments in individuals with CSU.
Methods: In this cross-sectional retrospective study, CSU patients that had undergone treatment with either antihistamines or omalizumab for a minimum of 12 weeks between 2015 and 2021 at an Allergy and Immunology Department were analyzed. Several demographic and laboratory parameters including eosinophil counts, mean platelet volüme (MPV), sedimentation, C-reactive protein (CRP), antinuclear antibodies (ANA) and Anti-thyroperoxidase (Anti-TPO) and total IgE, tryptase, ECP and D-dimer were retrived from patient files. The association of these biomarkers with Urticaria Control Test (UCT) and the effect of these biomarkers on treatment response were evaluated. Treatment response was assessed using the UCT, with a score of UCT ≥ 12 indicating a responder and UCT < 12 indicating a non responder.
Results: The patients in the omalizumab group were older, had a longer disease duration and had worse urticaria control (lower baseline UCT scores). 421 patients were treated with antihistamines and 88 patients were treated with omalizumab. ECP was found to be inversely correlated with baseline UCT (p < 0.001 r=-0.268). ECP and D-dimer levels of non-responder patients in the antihistamine group were significantly higher than in responder patients (ECP: 49 ng/mL vs 28.1 ng/mL, p < 0.001) (D-dimer: 0.60 mg/L vs 0.30 mg/L, p < 0.001), while there were no significant difference in terms of tryptase and total IgE. These four biomarkers were similar, in omalizumab responders and non responders.
Conclusion: In this study with CSU, we looked at predictors of responses to treatments. ECP can serve as a marker of poor urticaria control and may predict antihistamine refractoriness along with D-dimer.
简介:能够可靠预测抗组胺药和奥马利珠单抗治疗慢性自发性荨麻疹(CSU)疗效的生物标志物尚未最终确定。我们的目的是研究嗜酸性粒细胞阳离子蛋白(ECP)、胰蛋白酶、D-二聚体和总免疫球蛋白E(IgE)如何影响慢性自发性荨麻疹患者对抗组胺药和奥马珠单抗治疗的反应:在这项横断面回顾性研究中,分析了2015年至2021年间在过敏与免疫科接受抗组胺药或奥马珠单抗治疗至少12周的CSU患者。研究人员从患者档案中提取了一些人口统计学和实验室参数,包括嗜酸性粒细胞计数、平均血小板容积(MPV)、血沉、C反应蛋白(CRP)、抗核抗体(ANA)和抗甲状腺过氧化物酶(Anti-TPO)以及总IgE、胰蛋白酶、ECP和D-二聚体。评估了这些生物标志物与荨麻疹控制试验(UCT)的关联以及这些生物标志物对治疗反应的影响。治疗反应通过 UCT 进行评估,UCT 得分≥12 分表示有反应,UCT 得分≥12 分表示有反应:奥马珠单抗组患者年龄较大、病程较长、荨麻疹控制较差(基线 UCT 评分较低)。421名患者接受了抗组胺药治疗,88名患者接受了奥马珠单抗治疗。研究发现,ECP 与基线 UCT 成反比(p p p 结论:ECP 与基线 UCT 成反比:在这项关于 CSU 的研究中,我们研究了治疗反应的预测因素。ECP可作为荨麻疹控制不佳的标志物,并可与D-二聚体一起预测抗组胺药的难治性。

Background: Telemedicine became a fundamental part of healthcare provision during COVID-19 pandemic. An evaluation of telemedicine-associated satisfaction helps the service develop more viable applications. This review evaluated the satisfaction of healthcare users and providers and their willingness to use this modality in future.Methods: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A search on empirical articles published between March 2020 and December 2022 was performed on 'PubMed' and 'Scopus' databases. Findings that reported on satisfaction of patients, families and caregivers as well as clinicians were extracted and analysed. Quality of included studies was assessed. After applying inclusion and exclusion criteria, the review included 27 eligible studies.Results: Data was found from a variety of emergency and non-emergency departments of primary, secondary, and specialised healthcare. Almost all studies were undertaken within the NHS. There were many tools that measured satisfaction. Satisfaction was high among recipients of healthcare, scoring 9-10 on a scale of 0-10 or ranging from 73.3% to 100%. Convenience was rated high in every specialty examined. Satisfaction of clinicians was high throughout the specialities despite connection failure and concerns about confidentiality of information. Nonetheless, studies reported perception of increased barriers to accessing care and inequalities for vulnerable patients especially in older people. In general, willingness to use telemedicine in future was high in the recipients as well as the providers of healthcare.Conclusion: COVID-19 pandemic has transformed healthcare in the UK and promoted a revolution in telemedicine applications. Satisfaction was high among both recipient and provider of healthcare. Telemedicine managed to provide a continued care throughout the pandemic while maintaining social distance. The current review presented commendable evidence to encourage different specialities to engage in telemedicine application.

The study aimed to radiographically assess the characteristics of pulp stones (PS) and pulp canal obliteration (PCO) in teeth and examined their associations with various dental parameters such as caries, restorations, periodontal status, and age. This cross-sectional observational study was conducted at the Faculty of Dentistry, King Abdulaziz University between September 2022, and May 2023, involved 101 patients exhibiting 402 teeth with PS or PCO. Data were collected from periapical and bitewing radiographs, and analyzed by two calibrated dentists. Multiple dental parameters were assessed, including caries level, presence and level of restorations, periodontal condition, and age of the patient. The study population consisted of 62 females and 39 males, with an age range of 18-65 years. Inter- and intra-examiner reliability were high (Kappa = 0.88 and 0.98 respectively). PS were more commonly found in molars (81.2%), while PCO were presented in only 115 teeth (23%). Age significantly affected the type of calcification (p < 0.001), with PS more common in the 20-30 age group and PCO more common in individuals over 40. Presence of caries was significantly associated with the type of calcification (p = 0.013), but restoration was not. The majority of teeth with PS (76%) or PCO (93%) had healthy periodontium. Around 40% of teeth with PCO showed signs of periapical changes, a finding significantly different from those with PS (p < 0.001). Pulp calcifications were significantly associated with various dental parameters, including caries presence, age, and periodontal status. The findings provide crucial insights into the epidemiology and aetiology of pulp calcifications.
