    健康新生儿的肠道在出生时没有病毒,但迅速成为定殖正常的病毒共生,有助于重要的生理功能,如新陈代谢,但可以,在某些情况下,导致胃肠道疾病。然而,人们对这种殖民是如何开始的知之甚少,它的变异性和影响肠道病毒组成的因素。因此,了解发展,装配,肠道病毒群落随时间的发展是关键。探索生命早期病毒的发展,宏基因组测序应用于从17名婴儿出生后6个月内纵向收集的粪便样本.肠道病毒分析揭示了一个多样化和动态的病毒群落,由丰富的感染人类的不同病毒形成,非人哺乳动物,细菌,和植物。真核病毒早在生命一周就被发现,随着时间的推移,丰度和多样性不断增加。检测到的大多数病毒通常与胃肠炎有关,包括杯状病毒科的成员,小导航科,星状病毒科,腺病毒科,和Sedoreoviridae家族。最常见的共同事件涉及无症状的诺如病毒-parechovirus,诺如病毒-萨波病毒,沙波病毒-副病毒,在至少40%的样品中观察到。在婴儿肠道中检测到的大多数植物衍生病毒来自弗吉尼亚科。这项研究证明了婴儿胃肠道病毒的第一个纵向特征,从出生到6个月大,在撒哈拉以南非洲。总的来说,这项研究的发现描绘了健康婴儿肠道病毒随时间的组成和变异性,这是了解婴儿肠道病毒群落的动力学和生物地理学的重要一步。
    The gut of healthy neonates is devoid of viruses at birth, but rapidly becomes colonised by normal viral commensals that aid in important physiological functions like metabolism but can, in some instances, result in gastrointestinal illnesses. However, little is known about how this colonisation begins, its variability and factors shaping the gut virome composition. Thus, understanding the development, assembly, and progression of enteric viral communities over time is key. To explore early-life virome development, metagenomic sequencing was employed in faecal samples collected longitudinally from a cohort of 17 infants during their first six months of life. The gut virome analysis revealed a diverse and dynamic viral community, formed by a richness of different viruses infecting humans, non-human mammals, bacteria, and plants. Eukaryotic viruses were detected as early as one week of life, increasing in abundance and diversity over time. Most of the viruses detected are commonly associated with gastroenteritis and include members of the Caliciviridae, Picornaviridae, Astroviridae, Adenoviridae, and Sedoreoviridae families. The most common co-occurrences involved asymptomatic norovirus-parechovirus, norovirus-sapovirus, sapovirus-parechovirus, observed in at least 40 % of the samples. Majority of the plant-derived viruses detected in the infants\' gut were from the Virgaviridae family. This study demonstrates the first longitudinal characterisation of the gastrointestinal virome in infants, from birth up to 6 months of age, in sub-Saharan Africa. Overall, the findings from this study delineate the composition and variability of the healthy infants\' gut virome over time, which is a significant step towards understanding the dynamics and biogeography of viral communities in the infant gut.

    了解特定地区疾病的流行病学概况,可以适当规划预防公共卫生资源,早期诊断和治疗。在本研究中,我们描述了病毒的流行病学概况,真菌,国家地区医院(NDH)成人结核性和细菌性脑膜炎,自由邦省,三年以上(2017年1月至2019年12月)。
    回顾,所有成人脑膜炎病例的观察性研究,在国家地区医院(NDH)布隆方丹管理,自由州省,2017年1月至2019年12月之间的南非。
    在所审查的236份案卷中,大多数(93.2%;n=220)的脑膜炎患者是黑人,以及男性(55.5%;n=131)。在20至49岁之间发现较高的发病率(81.7%)。那些死去的人,大多数(n=14;63.6%)是男性,在40-49岁年龄组(n=7;31.8%),患有结核性脑膜炎(n=12;54.5%),HIV阳性(n=20;90.9%),并且细胞计数<100个细胞/mm3(n=10;45.5%)。
    我们的研究表明,结合患者人口统计信息,合并症,临床表现,和检查结果可以大大有助于提高临床怀疑,导致快速识别,诊断,以及对患者的治疗。
    UNASSIGNED: understanding the epidemiological profile of a disease in a particular region allows for proper planning of public health resources for prevention, early diagnosis and treatment. In this present study, we describe the epidemiological profile of viral, fungal, tuberculous and bacterial meningitis among adults at National District Hospital (NDH), Free State province, over three years period (January 2017 to December 2019).
    UNASSIGNED: a retrospective, observational study of all adult meningitis cases, managed at the National District Hospital (NDH) Bloemfontein, Free State Province, South Africa between January 2017 and December 2019.
    UNASSIGNED: of the 236 case files reviewed, majority (93.2%; n=220) of the patients managed for meningitis were black, as well as males (55.5%; n = 131). Higher incidence was found between the ages 20 to 49 (81.7%). Of those who died, the majority (n = 14; 63.6%) were males, in the age group 40-49 (n = 7; 31.8%), had TB meningitis (n = 12; 54.5%), were HIV positive (n = 20; 90.9%), and had cell count <100 cells/mm3 (n = 10; 45.5%).
    UNASSIGNED: our study suggests that combining information on patient demography, co-morbidities, clinical presentation, and examination findings can substantially contribute to raising clinical suspicion, leading to swift identification, diagnosis, and treatment of patients.

    BACKGROUND: Since the advent of democracy, the South African government has been putting charters, policies, strategies and plans in place in an effort to strengthen public health system performance and enhance service delivery. However, public health programme performance and outcomes remained poor while the burden of disease increased. This was also the case in the Free State Province, where major public health system challenges occurred around 2012. Assessment was necessary in order to inform health system strengthening.
    METHODS: The study entailed a multi-method situation appraisal utilising information collated in 44 reports generated in 2013 through presentations by unit managers, subdistrict assessments by district clinical specialist teams, and group discussions with district managers, clinic supervisors, primary health care managers and chief executive and clinical officers of hospitals. These data were validated through community and provincial health indabas including non-governmental organisations, councils and academics, as well as unannounced facility visits involving discussions with a wide range of functionaries and patients. The reports were reviewed using the World Health Organization health system building blocks as a priori themes with subsequent identification of emerging subthemes. Data from the different methods employed were triangulated in a causal loop diagram showing the complex interactions between the components of an (in) effective health system.
    RESULTS: The major subthemes or challenges that emerged under each a priori theme included: firstly, under the \'service delivery\' a priori theme, \'fragmentation of health services\' (42 reports); secondly, under the \'health workforce\' a priori theme, \'staff shortages\' (39 reports); thirdly, under the \'health financing\' a priori theme, \'financial/cash-flow problems\' (39 reports); fourthly, under the \'leadership and governance\' a priori theme, \'risk to patient care\' (38 reports); fifthly, under the \'medical products/technologies\' a priori theme, \'dysfunctional communication technology\' (27 reports); and, sixthly, under the \'information\' a priori theme, \'poor information management\' (26 reports).
    CONCLUSIONS: The major overall public health system challenges reported by stakeholders involved fragmentation of services, staff shortages and financial/cash-flow problems. In order to effect health systems strengthening there was particularly a need to improve integration and address human and financial deficiencies in this setting.
