Background

During the COVID-19 pandemic, several divergent mutants including the Omicron (B.1.1.529) BA.1 variant emerged, having a distinct mechanism of emergence compared with pre-existing variants of concern. Apart from playing a major role in causing recurrent epidemic waves, the highly divergent mutants also contributed to changing the fate of the pandemic by exhibiting large differences in phenotypic characteristics among even closely related variants. Given that several different variants emerged during the pandemic, the present study aimed to quantitatively evaluate the risk of emergence of divergent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutants and understand the mechanism of such emergence.

Methods

Upon identifying the emergence of phylogenetically distinct variants in “Omicron-like events” that have been recognized to date, a time-to-event analysis was carried out to estimate the monthly hazard rate of emergence. Four statistical models were established and compared using the Akaike Information Criterion.

Results

The model using the number of hospitalized cases was determined to be the best fit. The risk of Omicron-like events is not independent of time; instead, the monthly risk of emergence is likely to increase over time due to an increasing number of infection events.

Conclusions

Ongoing virus genomic surveillance is vital, and possible prevention among immunosuppressed individuals should be considered.
背景:在2019冠状病毒病大流行期间,出现了包括Omicron (B.1.1.529) BA.1变体在内的几种不同的突变体,与先前存在的变体相比,它们具有不同的出现机制。高度分化的突变体除了在引起反复出现的流行病浪潮中发挥主要作用外,甚至在密切相关的变体之间也表现出表型特征的巨大差异,从而有助于改变大流行的命运。鉴于在大流行期间出现了几种不同的变体,本研究旨在定量评估发散性严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)突变体出现的风险,并了解其出现的机制。方法:在确定迄今为止已识别的“类欧米克隆事件”中出现的系统发育上不同的变异后,进行了事件时间分析,以估计每月出现的危险率。采用赤池信息准则建立了4个统计模型并进行了比较。结果:采用住院病例数模型拟合效果最佳。类似欧米克隆事件的风险并非与时间无关;相反,由于感染事件数量的增加,每月出现的风险可能会随着时间的推移而增加。结论:持续的病毒基因组监测至关重要,应考虑在免疫抑制个体中进行可能的预防。

Background

Containment policies, also known as non-pharmaceutical interventions (NPIs), are crucial in managing emerging infectious diseases; however, their broader economic, social, and health impacts remain insufficiently understood. Previous studies have largely relied on aggregate indices, masking policy-specific effects and limiting their usefulness for preparedness and adaptive governance.

Methods

This study investigates how disaggregated containment measures affected international trade and the continuity of essential goods as a component of public health resilience. Using data from 182 countries during 2020–2021, we analyzed nine NPIs from the Oxford COVID-19 Government Response Tracker and international trade statistics across four product categories. Two indices, a conventional arithmetic mean and a novel entropy-weighted index, were constructed to capture policy intensity and cross-country heterogeneity. Panel regression models with fixed- and random-effects specifications were used to assess policy impacts.

Findings

Containment policies had heterogeneous effects on trade. Workplace closures were associated with trade resilience through digital adaptation, whereas stay-at-home orders and transport suspensions disrupted food and agricultural trade, revealing vulnerabilities in supply chains critical to health security. International travel restrictions correlated positively with goods trade, reflecting substitution from service- to goods-based activities. The entropy-weighted index outperformed the arithmetic mean by capturing policy variability, especially during 2020 early crisis phase.

Interpretation

Disaggregating NPIs reveals that policy design, timing, and institutional context shape both trade performance and health resilience. Integrating information-sensitive metrics such as entropy weighting can improve surveillance and preparedness frameworks. Policymakers should balance epidemiological effectiveness with the protection of essential trade flows to ensure equitable and adaptive pandemic governance.
背景:遏制政策,也称为非药物干预措施(npi),对于管理新发传染病至关重要;然而,对其更广泛的经济、社会和健康影响的了解仍然不够充分。以前的研究在很大程度上依赖于汇总指数,掩盖了特定于政策的影响,限制了它们对准备和适应性治理的有用性。方法本研究调查了分类控制措施如何影响国际贸易和作为公共卫生复原力组成部分的必需品的连续性。利用来自182个国家2020-2021年的数据,我们分析了来自牛津COVID-19政府应对跟踪系统的9个npi和四个产品类别的国际贸易统计数据。我们构建了两个指数,一个是传统的算术平均值,一个是新的熵加权指数,以捕捉政策强度和跨国异质性。使用具有固定效应和随机效应规格的面板回归模型来评估政策影响。研究发现,遏制政策对贸易的影响不尽相同。通过数字化适应,工作场所关闭与贸易韧性有关,而居家令和运输暂停则扰乱了粮食和农业贸易,暴露出对卫生安全至关重要的供应链的脆弱性。国际旅行限制与货物贸易呈正相关,反映了以服务为基础的活动向以货物为基础的活动的替代。熵加权指数的表现优于算术平均值,因为它捕捉到了政策的可变性,尤其是在2020年危机早期阶段。分析npi揭示了政策设计、时机和制度背景对贸易绩效和健康弹性的影响。集成信息敏感度量(如熵权)可以改进监视和准备框架。决策者应在流行病学有效性与保护基本贸易流动之间取得平衡,以确保公平和适应性的大流行病治理。

Background and aims

Staphylococcal pneumonia is a serious cause of morbidity and mortality in children worldwide, particularly in resource-limited settings. This study aimed to investigate the national epidemiology, clinical outcomes, and mortality-associated factors of pediatric staphylococcal pneumonia in Thailand.

Materials and methods

A nationwide retrospective study was conducted using the National Health Security Office (NHSO) database. All hospital admissions of children aged 1 month to < 18 years diagnosed with staphylococcal pneumonia (ICD-10-TM code J15.2) between 2015 and 2023 were included. Demographics, comorbidities, complications, interventions, and outcomes were analyzed. Multivariable logistic regression was used to identify factors independently associated with mortality.

Results

A total of 1718 admissions were analyzed. Annual admissions peaked at 249 in 2016 and were lowest at 129 in 2022. Most admissions were male (61.5 %) and infants under 1 year (34.2 %). Intubation was required in 60.9 % of cases, and 10.5 % underwent surgical interventions. The hospital mortality rate was 10.6 %. Factors associated with higher mortality included congenital heart disease (adjusted odds ratio [AOR] 3.57; 95 % CI 2.27–5.61), malignancy (AOR 4.13; 95 % CI 1.87–9.10), malnutrition (AOR 3.13; 95 % CI 1.45–6.75), acute respiratory distress syndrome (ARDS) (AOR 4.26; 95 % CI 2.23–8.14), septic shock (AOR 3.85; 95 % CI 2.52–5.90), acute renal failure (AOR 4.46; 95 % CI 2.72–7.30), disseminated intravascular coagulation (DIC) (AOR 2.13; 95 % CI 1.18–3.83), and need for endotracheal intubation (AOR 9.98; 95 % CI 4.50–22.15).

Conclusion

Pediatric staphylococcal pneumonia remains a significant clinical burden in Thailand, with high complication and mortality rates. Targeted interventions, particularly in high-risk populations, are essential to improve outcomes.
背景和目的葡萄球菌性肺炎是全世界儿童发病和死亡的一个严重原因,特别是在资源有限的地区。本研究旨在调查泰国儿童葡萄球菌性肺炎的全国流行病学、临床结果和死亡相关因素。材料与方法利用国家卫生安全办公室(NHSO)数据库进行了一项全国性的回顾性研究。纳入2015年至2023年期间所有住院诊断为葡萄球菌肺炎(ICD-10-TM代码J15.2)的1个月至 18岁儿童。分析了人口统计学、合并症、并发症、干预措施和结果。使用多变量逻辑回归来确定与死亡率独立相关的因素。结果共分析入院人数1718人。2016年全年入学人数达到249人的峰值,2022年最低,为129人。入院患者以男性(61.5% %)和1岁以下婴儿(34.2% %)居多。60.9% %的病例需要插管,10.5% %的病例需要手术干预。住院死亡率为10.6% %。与高死亡率相关的因素包括先天性心脏病(调整优势比[AOR] 3.57; 95 % CI 2.27-5.61)、恶性肿瘤(AOR 4.13; 95 % CI 1.87-9.10)、营养不良(AOR 3.13; 95 % CI 1.45-6.75)、急性呼吸窘迫综合征(ARDS) (AOR 4.26; 95 % CI 2.23-8.14)、感染性休克(AOR 3.85; 95 % CI 2.52-5.90)、急性肾功能衰竭(AOR 4.46; 95 % CI 2.72-7.30)、弥散性血管内凝血(AOR 2.13;95 % CI 1.18-3.83),需要气管插管(AOR 9.98; 95 % CI 4.50-22.15)。结论在泰国,儿童葡萄球菌肺炎仍然是一个重要的临床负担,其并发症和死亡率都很高。有针对性的干预措施,特别是针对高危人群的干预措施,对于改善结果至关重要。

Tuberculous meningitis (TBM) typically presents with neurological symptoms. Voiding dysfunction in TBM is usually attributed to spinal cord involvement. We report a rare case of possible TBM co-existing with possible prostatic tuberculosis, presenting primarily with urinary symptoms in the absence of spinal pathology. A 69-year-old male presented with a two-year history of progressive urinary retention, urgency, and frequency. Initial management for benign prostatic hyperplasia was ineffective. He subsequently developed fever, headache, and dizziness. Cerebrospinal fluid (CSF) analysis revealed lymphocytic pleocytosis and elevated protein. Despite extensive testing, including CSF culture, Xpert MTB/RIF, and metagenomic next-generation sequencing (mNGS), no pathogen was identified. However, a history of untreated testicular tuberculosis, pulmonary nodules on CT, and a prostatic nodule on MRI raised suspicion of disseminated tuberculosis. A clinical diagnosis of possible TBM was made based on a Marais score of 11. An intensive anti-tuberculosis regimen including moxifloxacin and linezolid led to complete resolution of neurological and urinary symptoms. This case suggests that voiding dysfunction in TBM patients may stem from concurrent genitourinary tuberculosis rather than spinal cord involvement. It highlights the importance of considering hematogenous dissemination from latent genitourinary foci in elderly patients and the utility of the Marais criteria for the diagnosis of TBM when microbiological evidence is elusive.
结核性脑膜炎(TBM)通常表现为神经系统症状。TBM的排尿功能障碍通常归因于脊髓受累。我们报告一例罕见的结核病合并前列腺结核的病例,主要表现为泌尿系统症状,没有脊柱病理。一名69岁男性,有2年进行性尿潴留、尿急和尿频病史。良性前列腺增生的初始治疗是无效的。他随后出现发烧、头痛和头晕。脑脊液(CSF)分析显示淋巴细胞增多和蛋白升高。尽管进行了广泛的测试,包括CSF培养,Xpert MTB/RIF和宏基因组下一代测序(mNGS),但没有发现病原体。然而,未经治疗的睾丸结核史,CT上的肺结节和MRI上的前列腺结节引起了对播散性结核的怀疑。根据Marais评分为11分,临床诊断可能为TBM。包括莫西沙星和利奈唑胺在内的强化抗结核方案导致神经和泌尿系统症状的完全解决。本病例提示TBM患者的排尿功能障碍可能源于并发泌尿生殖系统结核,而不是脊髓受累。它强调了考虑老年患者潜伏性泌尿生殖系统病灶的血液传播的重要性,以及当微生物证据难以捉摸时,Marais诊断TBM标准的实用性。
