Genital herpes (GH), historically associated with herpes simplex virus type 2 (HSV-2), is changing its etiology. Since the last few decades, there has been an increase in genital infections caused by herpes simplex virus type 1 (HSV-1). In fact, in several countries, preferably in high-income regions such as North America or Western Europe, HSV-1 has become the leading cause of first-episode GH, especially among adolescents and young adults. However, the epidemiological trend varies geographically, with slower changes observed in Africa, Latin America, and Southeast Asia, where GH HSV-2 remains dominant. This epidemiological shift may be mainly due to the decline in HSV-1 seroprevalence, decreased childhood exposure to the virus, and changes in sexual practices. Despite the global decline in HSV-1 seroprevalence, GH caused by HSV-1 is rising by 1–2% annually in many areas. This review summarizes the seroprevalence of HSV-1/-2 worldwide in recent decades and discusses the changes in GH etiology and contributing factors. Despite the substantial global burden of the disease and its psychosocial impact, no vaccine or curative treatment exists. Active surveillance, health and sexual health education, and targeted interventions are vital to manage this changing landscape and to mitigate the public health issue posed by GH and HSV-1.

Background
Some studies have suggested an association between Enterococcus faecalis blood stream infection (BSI) and colorectal cancer (CRC) suggesting that screening for CRC could be reasonable. However, these studies were limited by small numbers with low generalizability.
Methods
Danish nationwide registries were used to identify patients with first-time E. faecalis BSI from 2010 to 2021 without previous colorectal neoplasia (CRN). Age-, sex- and calendar-matched comparators from the general population were identified (1:5). We estimated the six-month cumulative incidence of CRC and CRN and a multivariable adjusted Cox analysis was used for relative comparison between groups.
Results
We identified 4664 patients with E. faecalis BSI (median age: 74.9 years, 73.4% males) and 23,320 comparators from the general population. For patients with E. faecalis BSI the six-month incidence of CRC was 0.45% (95% CI: 0.28–0.72%) and of CRN 2.34% (95% CI: 1.88–2.88). For matched comparators the incidence of CRC was 0.12% (95% CI: 0.08–0.17) and of CRN 0.48% (95% CI: 0.39–0.57). In adjusted analysis, patients with E. faecalis BSI had a higher HR of CRC (HR=3.70 (95% CI: 1.91–7.19) and CRN (HR=4.64 (95% CI: 3.40–6.34) than matched comparators. The six-month mortality was 36.3% in patients with E. faecalis BSI while this was 1.7% among comparators.
Conclusion
In patients with first-time E. faecalis BSI the six months incidence of CRC was around 0.5% and 2.3% for the diagnosis of CRN, which were 3–4 times higher than in a matched cohort from the general population. Nevertheless, the absolute risks do not justify systematic screening for CRC or CRN in patients with E. faecalis BSI.

Objectives
Candidemia is a severe complication in critically ill and immunocompromised patients, and is associated with high morbidity and mortality. While early fungal clearance may improve outcomes, the association between follow-up blood culture (FUBCs) results and clinical outcomes remains insufficiently explored. This sub-analysis of the ECMM Candida III study investigates predictors of persistent candidemia and the impact of positive FUBC results on clinical outcomes.
Methods
The multicenter ECMM Candida III study enrolled adults with culture-proven candidemia from 60 European centers (2018–2019). This sub-analysis included patients with at least one FUBC result reported (n = 258; 40.8%). Statistical analysis used SPSS 29 and R. Binary logistic regression was used to identify predictors of persistent candidemia. To assess mortality risk factors, Cox proportional hazards regression models were constructed.
Results
Of 258 patients, 52 (20.2%) had persistent candidemia based on positive FUBCs (median duration of candidemia 6 days). Utilization of echinocandins as first line treatment was less frequent (61.5% vs. 78.2%; p=0.014) in those with positive FUBCs. Mortality was significantly higher in the FUBC-positive group (50% vs. 32%; p=0.016). In the multivariable logistic regression model, lower EQUAL Candida Scores, reflecting reduced adherence to guideline-recommended management, were independently associated with persistent candidemia (OR 0.003, 95% CI 0.0002–0.07; p<0.001). Univariable Cox regression identified persistent candidemia ≥5 days (HR 2.16; 95% CI 1.33–3.53; p= 0.002) as a significant predictor of mortality. In the multivariable Cox regression model, intensive care unit (ICU) admission (HR 1.59, 95% CI 1.02–2.50; p= 0.039) and persistent candidemia ≥5 days (HR 2.06, 95% CI 1.26–3.37; p= 0.004) remained independent predictors of mortality.
Conclusion
Persistent candidemia was predicted by poor adherence to treatment guidelines, as shown by low EQUAL Candida Scores, particularly due to the lack of initial echinocandin use. After controlling immortal time bias, persistent candidemia ≥5 days and ICU admission remained independent predictors of mortality in the multivariable model.
目的：念珠菌病是危重症和免疫功能低下患者的严重并发症，具有高发病率和高死亡率。虽然早期真菌清除可能改善预后，但随访血培养（fubc）结果与临床结果之间的关系仍未得到充分探讨。ECMM念珠菌III研究的亚分析研究了持续性念珠菌的预测因素以及FUBC阳性结果对临床结果的影响。方法：多中心ECMM念珠菌III研究招募了来自欧洲60个中心（2018-2019）的培养证实念珠菌病的成人。该亚组分析包括至少有一个报告的FUBC结果的患者（n = 258; 40.8%）。采用SPSS 29和SPSS r进行统计学分析。采用二元logistic回归确定持续性念珠菌的预测因素。为评估死亡危险因素，构建Cox比例风险回归模型。结果：258例患者中，52例（20.2%）存在基于fubc阳性的持续性念珠菌病（念珠菌病中位持续时间6天）。在fubc阳性的患者中，使用棘白菌素作为一线治疗的频率较低（61.5%比78.2%;p=0.014）。fubc阳性组的死亡率显著高于对照组（50% vs. 32%; p=0.016）。在多变量logistic回归模型中，较低的EQUAL念珠菌评分，反映了对指南推荐管理的依从性降低，与持续性念珠菌血症独立相关（OR 0.003, 95% CI 0.0002 - 0.07）。结论：持续性念珠菌血症的预测与对治疗指南的依从性较差有关，如较低的EQUAL念珠菌评分所示，特别是由于缺乏初始使用棘白菌素。在控制存活时间偏差后，在多变量模型中，持续念珠菌≥5天和入住ICU仍然是死亡率的独立预测因子。资金来源：研究者发起的研究基金从Scynexis和Mundipharma获得，以支持该研究。

Objectives
We evaluated the efficacy, safety and impact on viral reservoir of rapid bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) initiation during primary HIV infection (PHI).
Methods
Multicenter, single-arm clinical trial in participants with PHI of <3 months (seroconversion or incomplete serological pattern), starting BIC/FTC/TAF in 6 Spanish centers between January-2021 and September-2022. Primary endpoint was proportion of participants with viral load (VL)<50 copies/mL at 48-weeks on the Intention-to-treat-exposed population (ITTe). Cases were compared with randomly-matched retrospective PHI controls, starting other 3-drug Integrase-Strand-Transfer-inhibitor-based regimens. Reservoir was evaluated in PHI cases by Intact Proviral DNA Assay (IPDA).
Results
We included 64 participants, 94% cis-male, aged 32 (26;41) years.; 78% men-who-have-sex-with-men. At BIC/FTC/TAF initiation, Fiebig stages were II (14%), III (11%); IV (5%), V (54%) and VI (16%); VL was 496,520 (110,000;1,285,000) copies/mL; 62% were subtype B; median (IQR) CD4 T cell count was 406 (322;535) cells/µL; 6% had active hepatitis B virus co-infection. All participants started BIC/FTC/TAF at first specialist consultation. 81% (ITTe) and 93% (On-Treatment, OT) had VL<50 copies/mL at 48-weeks. 72% had adverse events, only 3% were grade 3/4; 91% were not-related, none led to BIC/FTC/TAF-discontinuation. 92% of controls (OT) had VL<50 copies/mL at 48-weeks (p=0.914), 11% (17%) modified initial antiretroviral regimen (p>0.001). Intact and defective proviral DNA levels significantly decreased at 48-weeks.
Conclusions
BIC/FTC/TAF showed rapid viral decay, high suppression rates, good tolerability, and reservoir decline in PHI, making it an appealing regimen in this setting.

This review outlines recent trends on invasive meningococcal disease (IMD) discussed at the latest meeting of the Global Meningococcal Initiative (GMI). There has been a re-emergence of the Hajj strain sublineage (serogroup W; ST-11 clonal complex), with travel to the Kingdom of Saudi Arabia being a critical factor in transmission. The epidemiology of IMD has also changed following the COVID-19 pandemic, with annual IMD cases increasing in many countries. For example, the highest number of IMD cases since 2014 was reported in the USA in 2023–2024. Atypical presentations of IMD have been prominent irrespective of the pandemic. For instance, an increase in cases of meningococcal epiglottitis has been reported in France in 2022–2023 (serogroups W and Y). When considering vaccination, the GMI has identified a need for broader meningococcal serogroup B (MenB) immunisation owing to the potential impact of the vaccines on reducing IMD incidence caused by other serogroups than MenB. There is also a case for using MenB vaccination to protect against Neisseria gonorrhoeae infection based on initial evidence, albeit further studies will need to be conducted.

Although cases of nontuberculous mycobacteria (NTM) pulmonary disease (NTMPD) are rapidly increasing primarily in individuals over the age of 65, the host factors leading to higher occurrence in immunocompetent older patients remain elusive. This study aims to elucidate host factors leading to higher nontuberculous mycobacterial pulmonary disease occurrence in older immunocompetent patients.
Methods
To address these challenges, we used a rhesus macaque model developed by our laboratory where macaques were infected via intrabronchial inoculation with M. avium subsp. hominissuis (MAH). Disease progression, bacterial load, microbial community compositions, and host responses were monitored longitudinally using computed tomography, culturing, 16S amplicon sequencing, histology, flow cytometry, and single cell RNA sequencing.
Results
Despite comparable kinetics of bacterial clearance, computed tomography scans indicated more severe radiological outcomes in older animals which mounted predominantly an inflammatory acute phase response rather than a Th1 response. Single cell RNA sequencing indicated a persistent inflammatory signature in aged animals. Microbial community analysis revealed an age-mediated loss of an uncultured Tropheryma species that was inversely correlated with severity of radiographic changes.
Conclusions
These data reveal that nontuberculous mycobacterial pulmonary disease severity in the aged animals is driven by dysregulated inflammatory responses and dysbiosis of the lung microbiome.
