Identification and characterization of clinical isolates of members of the Staphylococcus sciuri group

A total of 28 staphylococcal isolates from human clinical specimens belonging to the Staphylococcus sciuri group were identified and characterized. The API Staph and ID32 STAPH correctly identified S. sciuri and S. lentus but not S. vitulinus strains. Identification to the subspecies level was possible only by a PCR-based method.

Influence of Social Support,Work Overload,and Parity on Pregnant Career Women's Psychological Well‐Being

The influence of social support, work overload, and parity on psychological well‐being of pregnant career women was investigated. Women executives (N200) attending antenatal clinics were selected. A 2 × 2 × 2 analysis of variance (ANOVA) revealed significant independent influence of social support (F(1, 199) = 26.51, p < 0.05) and work overload (F(1, 199) = 461.76, p < 0.05), and significant joint effect of social support and work overload. There was no significant effect of parity (F(1, 199) = 0.72, p > 0.05). Combinations of parity, social support, and work overload were also not significant (F(1, 199) = 0.80, p > 0.05). Social support and appropriate work incentives are helpful in assisting pregnant women executives in coping with psychological changes during pregnancy.     

Overview and update on molecular testing in non-small cell lung carcinoma utilizing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) samples

Lung carcinoma remains one of the most frequent and aggressive human neoplasms. Fortunately, in the last decades, the increasing knowledge of the molecular mechanisms leading to cancer development has allowed the use of targeted therapies with improvement of prognosis in many patients. Clinical management has also changed after the introduction of endobronchialultrasonographic bronchoscopy that allows a conservative staging of lung tumors, avoiding the need of mediastinoscopy for lymph node staging. Lung pathologists and cytopathologists are facing the challenge of giving the more comprehensive prognostic and predictive information with ever smaller tissue or cytological samples. The aim of this review is to summarize the molecular testing for non-small cell lung carcinoma and how pathologists can contribute to the patient's outcome with a conscious management of biological samples.     

Impact of COVID‐19 on access to healthcare in low‐ and middle‐income countries: Current evidence and future recommendations

The COVID‐19 pandemic continues to be a major public health threat globally and low‐ and middle‐income countries (LMICs) are not an exception. The impact of the COVID‐19 pandemic is far‐reaching on many areas including but not limited to global health security, economic and healthcare delivery with a potential impact on access to healthcare in LMICs. We evaluate the impact of the COVID‐19 pandemic on access to healthcare in LMICs, as well as plausible strategies that can be put in place to ensure that the delivery of healthcare is not halted. In order to mitigate the devastating effect of the COVID‐19 pandemic on the already weak health systems in LMICs, it is much necessary to reinforce and scale up interventions and proactive measures that will ensure that access to healthcare is not disrupted even in course of the pandemic.     

To what extent do community characteristics drive health facility delivery? Findings among Women who had recent live births in Nigeria

Existing studies have established several individual drivers of health facility delivery in many developing countries. However, the community characteristics that drive health facility delivery have been less studied across developing countries. This study thus examines the extent to which community characteristics drives health facility delivery among women who had recent live births in Nigeria based on data from the 2018 Nigeria Demographic and Health Survey (NDHS). A weighted sample size of 7,342 women was analysed. The outcome variable was health facility delivery. The explanatory variables were selected individual and community characteristics. Results show 39.7% prevalence of health facility delivery among the women. Findings further reveals that the community characteristics have significant effects on the variations in health facility delivery across the communities. Community characteristics significantly drive health facility delivery in Nigeria. More community-based priority actions are required to improve demand for health facility delivery in the country.     

碱离子水饮用后血小板聚集率的的变化(附30例报告)

目的:报告30例饮用豪斯牌碱离子水前、后血小板聚集率的变化。方法:饮用碱离子水前、后(2～3月,>3～6月)作比浊法血小板聚集试验,以1分钟、5分钟及5分钟内最大聚集率(Max％)为指标,同时检测部分血粘度指标及凝血因子,并用自动生化仪检测血糖、血脂、主要电解质及部分肝、肾功能。结果:饮碱离子水后,血小板聚集率明显下降,而以疾病组(Max>80％)下降尤为明显,P均<0.001。饮碱离子水后血小板聚集率的下降,部分可能与损伤的血管内皮得到修复有关。主要电解质及部分肝、肾功能无明显异常改变。结论:由于心、脑血管血栓性疾病患者血小板聚集率多明显升高,饮碱离子水后血小板聚集率明显下降,且长期饮用对主要电解质及部分肝、肾功能无明显异常改变,作者认为碱离子水使用方例、安全、有效、价廉,因而对心、脑血管血栓性疾病防治方面可能是一种积极的辅助方法,值得临床进一步探索。     

Prevalence of EBV infection in 1157 diseased cohorts in Nigeria: A systematic review and meta-analysis

BackgroundEpstein-Barr virus (EBV) is a member of the herpesvirus family that is known to ubiquitously infect people worldwide. However, the actual prevalence of EBV infection in diseased patients in Nigeria, remains unknown. This study was thus conducted to ascertain the true prevalence.MethodsA systematic review and meta-analysis of published data was conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Electronic databases including PubMed, Scopus, ScienceDirect, and Google Scholar were searched for studies reporting the occurrence of EBV infection among patients with established diseases. Studies were included if they assessed EBV infection in diseased patients in Nigeria. Data were extracted and subsequently analysed using R software. Funnel plot and Egger's regression test was used to assess publication bias, while JBI prevalence tool was used to assess study quality.ResultsA total of 13 studies covering 228 cases of EBV infection among 1157 diseased patients were included. Summary estimates were computed using random-effects model. The pooled prevalence of EBV infection was 20.3% (95% CI: 10.8–34.9, I² ?= ?92.26, p ?< ?0.001). When stratified according to the type of disease, higher estimates were obtained for patients suffering from Kaposi's sarcoma (98.7%, 95% CI: 82.2–99.9) and Nasopharyngeal malignancy (85.7%, 95% CI: 70.0–93.9). A prevalence of 13.4% (95% CI: 6.0–27.4) and 12.2% (95% CI: 4.8–27.8) was derived for the most reported patient populations, lymphoma and HIV, respectively.ConclusionThis first meta-analysis on the prevalence of EBV among Nigerian patients suffering from various diseases reveals a prevalence that emphasises the need to routinely monitor EBV infection in all EBV-associated diseases in Nigeria.
