Purpose
Emergency room (ER) physicians must deal with patients with clinically suspected symptoms, such as dyspnea, cough, and increased sputum production, on the frontlines of medical care if patients present with severe chronic obstructive pulmonary disease (COPD). This study aims to investigate the longitudinal tendencies of COPD-related ER visits.
Patients and methods
A total of 360,313 patients were included in this study. The COPD-related ER visit rates between 2001 and 2015 were categorized using the International Classification of Disease (ICD) codes (496). The effects of age, period, and cohort on COPD-related ER visit rates were determined using an age-period-cohort (APC) model.
Results
Age was associated with a high risk of COPD in the pediatric and older populations. A significant increase was observed in the period effect, from 2001 to 2015. The cohort effect tended to oscillate from 1918 to 1973, and was reversed in the latest cohort. Furthermore, the COPD-related ER visit rate increased between 2001 and 2015 in both men and women.
Conclusion
Age, period, and cohort were observed to increase COPD visit rates. The APC model can be used to determine trends in COPD-related ER visits.

Helicobacter pylori (H. pylori), a pervasive pathobiont, colonizes the gastric mucosa and plays a crucial role in the pathogenesis of several gastroduodenal pathologies ranging from chronic gastritis to more severe disorders including peptic ulcer disease, gastric mucosa-associated lymphoid tissue lymphoma, and gastric adenocarcinoma. In symptomatic patients, endoscopy and histological examination of the gastric mucosa are the preferred tests for diagnosing H. pylori. Our study aimed to identify the frequency of H. pylori and its association with endoscopic and histopathological findings in adult Lebanese patients. Thus, 332 symptomatic adult patients, attending the Endoscopy unit of Makassed General Hospital in Beirut, were enrolled in this cross-sectional study. Overall, 14.16 % of the patients were infected with H. pylori, with male predominance. The most common endoscopic findings were gastritis and gastropathy. Moreover, H. pylori infection was significantly associated with gastric ulcers and duodenitis. On the other hand, active gastritis and chronic gastritis were the most common histopathological findings. Chronic gastritis was more frequent in H. pylori-positive patients. The association between endoscopic diagnosis and histopathological findings was then assessed. It was shown that gastropathy was significantly associated with chronic gastritis. In addition, gastric ulcer was significantly related to active gastritis and chronic gastritis. In conclusion, this study reported various endoscopic findings in H. pylori-positive patients based on the Kyoto classification. This highlights the importance of invasive diagnosis in symptomatic patients. Therefore, a combination-based approach including endoscopic and histopathological findings remains crucial in clinical practice for a definitive and accurate diagnosis of H. pylori infection and related disorders, especially in resource-limited settings.
幽门螺杆菌(Helicobacter pylori, H. pylori)是一种普遍存在的病原菌,它在胃粘膜上定植,在胃十二指肠多种疾病的发病机制中起着至关重要的作用,从慢性胃炎到更严重的疾病,包括消化性溃疡疾病、胃粘膜相关淋巴组织淋巴瘤和胃腺癌。对于有症状的患者,内镜检查和胃粘膜组织学检查是诊断幽门螺杆菌的首选检查。我们的研究旨在确定黎巴嫩成年患者幽门螺杆菌的频率及其与内窥镜和组织病理学结果的关系。因此,在贝鲁特Makassed总医院内窥镜检查部门就诊的332名有症状的成年患者被纳入了这项横断面研究。总体而言,14.16 %的患者感染幽门螺杆菌,以男性为主。最常见的内窥镜检查结果是胃炎和胃病。此外,幽门螺杆菌感染与胃溃疡和十二指肠炎显著相关。另一方面,活动性胃炎和慢性胃炎是最常见的组织病理学表现。慢性胃炎在幽门螺旋杆菌阳性患者中更为常见。然后评估内窥镜诊断与组织病理学结果之间的关系。结果表明,胃病与慢性胃炎有显著相关性。此外,胃溃疡与活动性胃炎和慢性胃炎有显著相关性。总之,本研究报告了基于京都分类的幽门螺杆菌阳性患者的各种内镜检查结果。这突出了有症状患者侵入性诊断的重要性。因此,在临床实践中,特别是在资源有限的情况下,包括内镜和组织病理学检查结果在内的综合方法对于确定和准确诊断幽门螺杆菌感染和相关疾病仍然至关重要。

Background
With the outbreak of COVID-19 in China, a large number of COVID-19 patients are at risk of long COVID after recovery. The purpose of our research is to systematically review the existing clinical studies to understand the current prevalence and related risk factors of long COVID in COVID-19 patients in China.
Methods
The protocol of this systematic review was registered on PROSPERO (CRD42024519375). We searched six electronic databases from 1st January 2020–1st March 2024. Literature screening, data extraction, and risk bias assessment were independently carried out by two reviewers. Quality of the included studies was evaluated by AHRQ and NOS. The meta-analysis was performed by R software 4.2.3 to derive the prevalence of long COVID and risk factors.
Results
Overall, 50 studies with 65880 participants were included. The results showed that the prevalence of long COVID (with at least one symptom) among the COVID-19 patients was approximately 50 % (95 %Confidence Interval (CI) 42–58 %) in China. Although we conducted meta-regression and subgroup analysis, the heterogeneity of the study was high. But the Omicron BA.2 variant had a statistically significant effect on the prevalence of long COVID (P = 0.0004). The three most common symptoms of long COVID were fatigue (0.33, 95 %CI 0.28–0.39), cognitive decline (0.30, 95 %CI 0.14–0.46) and shortness of breath (0.29, 95 %CI 0.15–0.43). Patients with severe acute phase of COVID-19 (Odds Ratio (OR) 1.57, 95 % CI 1.39–1.77), combined 2 comorbidities (OR 1.80, 95 % CI 1.40–2.32), combined 3 comorbidities (OR 2.13, 95 % CI 1.64–2.77), advanced age (OR 1.02, 95 % CI 1.01–1.04), female (OR 1.58, 95 % CI 1.44–1.73) were the risk factors for long COVID prevalence.
Conclusion
Current systematic review found that nearly half of COVID-19 patients may suffering from long COVID in China. Establishing a long COVID recovery-support platform and regular follow-up would help to long-term monitor and manage the patients, especially those high-risk population.
背景:随着新冠肺炎疫情在中国的爆发,大量新冠肺炎患者在康复后面临长期感染的风险。我们的研究目的是系统回顾现有的临床研究,了解中国COVID-19患者长冠状病毒的流行现状及其相关危险因素。方法:本系统评价的方案在PROSPERO注册(CRD42024519375)。检索了2020年1月1日至2024年3月1日的6个电子数据库。文献筛选、资料提取和风险偏倚评估由两位审稿人独立进行。采用AHRQ和NOS对纳入研究的质量进行评估。采用R软件4.2.3进行meta分析,得出长冠状病毒感染率和危险因素。结果:总共纳入了50项研究,65880名参与者。结果显示,中国COVID-19患者中长冠状病毒(至少有一种症状)的患病率约为50% %(95% %可信区间(CI) 42-58 %)。虽然我们进行了meta回归和亚组分析,但研究的异质性较高。但Omicron BA.2变异对长COVID的患病率有统计学意义(P = 0.0004)。长冠肺炎的三个最常见症状是疲劳(0.33,95 %CI 0.28-0.39)、认知能力下降(0.30,95 %CI 0.14-0.46)和呼吸短促(0.29,95 %CI 0.15-0.43)。COVID-19严重急性期患者(比值比(OR) 1.57, 95 % CI 1.39-1.77)、合并2种合并症(OR 1.80, 95 % CI 1.40-2.32)、合并3种合并症(OR 2.13, 95 % CI 1.64-2.77)、高龄(OR 1.02, 95 % CI 1.01-1.04)、女性(OR 1.58, 95 % CI 1.44-1.73)是COVID-19长期流行的危险因素。结论:目前的系统评价发现,中国近一半的COVID-19患者可能患有长期COVID。建立长效康复支持平台,定期随访,有利于对患者特别是高危人群进行长期监测和管理。

Background
Data on the natural history of the community-acquired RSV in adult outpatients are limited. It is also unclear whether the existing influenza surveillance platforms based on influenza-like illness (ILI) case definitions are efficient for RSV. The two-season RESPIRA-50 study was established in 2023 to identify an optimal RSV case definition and to explore the natural history of RSV. Here, the first-season results are reported.
Methods
The study was conducted in Genoa (Italy) during the 2023/2024 RSV season. Twenty-four general practitioners were randomized 1:1 to enroll adults aged ≥ 50 years seeking care for acute respiratory infection (ARI) or ILI, respectively. Both syndromes were defined according to the European criteria. All subjects were tested by real-time polymerase chain reaction (RT-PCR) for RSV and other pathogens. RSV-positive adults were followed for up to 30 days.
Results
Of 517 subjects included, 7.0 % [95 % confidence interval (CI): 4.9–9.5 %)] tested positive for RSV. RSV prevalence in the ARI group (8.0 %; 95 % CI: 5.0–12.1 %) was higher than in the ILI group (6.0 %; 95 % CI: 3.5–9.5 %) with an odds ratio of 1.36 (95 % CI: 0.69–2.70). Conversely, positivity for influenza (10.4 % vs 12.4 %) and SARS-CoV-2 (12.4 % vs 16.9 %) were lower in the ARI group and the corresponding ORs were 0.82 (95 % CI: 0.48–1.42) and 0.70 (95 % CI: 0.43–1.15), respectively. The mean duration of an RSV episode was 18.8 ± 8.0 days and two thirds of individuals were prescribed antibiotics. A total of 33.3 % (95 % CI: 18.6–51.0 %) of RSV-positive individuals developed complications, of which bronchitis (13.9 %) and pneumonia (8.3 %) were the most frequent.
Conclusions
Compared with ARI, ILI-based surveillance may underestimate the burden of RSV in community-dwelling adults aged ≥ 50 years. A high proportion of RSV-positive adult outpatients develops complications, which lead to substantial resource consumption.

Background
Group A Streptococci (GAS) may cause infections of the pharynx and soft tissues and invasive infections in children (iGAS). A significant increase in severe iGAS infections has been reported in Europe since the fall of 2022.
Objectives
This retrospective study aims to analyse clinical data of children with invasive and non-invasive GAS infections in the post-COVID-19 pandemic era, searching for predisposing factors to developing invasive infections.
Methods
History and clinical data of patients hospitalised due to or with coexisting GAS infections were analysed. iGAS and non-iGAS infections were compared.
Results
The cohort comprised 45 children (median age 7 years). 31(69 %) children developed iGAS infections - sepsis with toxic shock syndrome (TSS) (4 children-13 %), deep soft tissue infections (3–10 %), meningitis (2–6 %), pneumonia (2–6 %) or respiratory tract infections – sinusitis or otitis (4–12 %). iGAS children developed complications more frequently (100 % vs 21 %, p < 0.0001) and required prolonged treatment (median 15 vs 10 days, p = 0.0001). Preceding or coexisting viral infections were more common in iGAS children (87 % vs 14 %; p < 0.0001). CRP and PCT were significantly higher in the iGAS group (median 17.95 vs 3.97 mg/dl, p = 0.0002; 6.8 vs 0.05 ng/ml, p = 0.0001, respectively). The multiple logistic regression revealed that preceding or coexisting viral infections and the rise in CRP level increased the risk of iGAS infections. The CRP cut-off > 14.94 mg/dl showed 68.2 % sensitivity (CI 45.13–86.14 %) and 100 % specificity (69.15–100 %).
Conclusion
Our study shows increased incidence and severity of GAS infections among hospitalised children. Previous or coexisting viral infections and CRP with cut-off > 14.94 mg/dl were significant risk factors.

Background
CareHPV is a highly promising screening HPV assay that functions as a simplified and rapid point-of-care test, making it particularly well-suited for low-resource areas. It exhibits high sensitivity for detecting cervical precancerous lesions in cross-sectional study design. However, there is still limited evidence on the long-term protection of careHPV testing in the practical setting.
Methods
A government-led cervical cancer screening program was implemented in Ordos City, China, specifically targeting female residents aged 35–64 years since 2016. CareHPV specimens were collected and visual inspection with acetic acid and Lugol iodine (VIA/VILI) was performed in the baseline screening. Women who were HPV-positive or VIA/VILI-suspected cancer at baseline were invited for a one-year follow-up screening. At the same time, those who were HPV-negative were scheduled for a 5-year rescreening. Women diagnosed with cervical intra-epithelial neoplasia grade 2 or worse (CIN2+) would be referred to clinical treatment as per the clinical guidelines. The current study includes participants who had valid baseline screening results and attended follow-ups with valid careHPV results conducted between January 2017 and December 2021, aiming to assess the long-term risk stratification for careHPV. Cumulative incidence rate (CIRs) and hazard ratio (HRs) for CIN2+ were calculated, using survival analysis.
Results
Among the 179,306 women enrolled in the baseline screening between 2016 and 2020, 12.60 % tested positive for careHPV, with 657 cases of CIN2+ identified. The final analysis included 18,562 women in our study, of whom 58.54 % were careHPV-positive at baseline. The final analysis consisted of 17,905 women who underwent screening between 2016 and 2020 and attended follow-ups from 2017 to 2021, with valid HPV results, and 657 women who identified as CIN2+ at the baseline. The 5-year CIRs were 0.003 and 0.101 among women who tested negative and positive for baseline careHPV, respectively. The 5-year CIRs for developing CIN2+ during follow-ups were 0.009, 0.009, and 0.11 for the groups of women who transitioned from careHPV-negative to positive (831, 4.64 %), careHPV-positive to negative (6688, 37.35 %), and maintained a stable positive careHPV status (3535, 19.74 %), respectively.
Conclusions
Our findings support the long-term safety and protection of careHPV testing in 5-year follow-ups of screening programs. CareHPV represents a viable option for regions with limited healthcare resources.

Amidst the global challenges of the 21st century, an urgent call emerges to redefine global public health in response to the multifaceted threats of climate change, political denial, and systemic barriers. This study employs a critical analysis approach, combining a narrative literature review with Action Research, to assess the health impacts of climate change and identify pathways for resilience. Direct and indirect implications—ranging from heat-related illnesses and vector-borne diseases to mental health challenges and displacement—are highlighted, alongside barriers posed by governance structures and economic disparities. A novel collaborative framework, CLIMBED COOL, is introduced, emphasizing adaptation, transformation, and transition as key strategies to address these challenges. Findings also underscore the importance of robust education, simulation-based training, and structured data-sharing mechanisms through regional Centers for Disease Control and Prevention and global databases. This study advocates for a paradigm shift in global governance and collaboration, ensuring holistic and sustainable solutions for future generations.

Background
Few studies have evaluated antibiotic prescribing practices for bacterial enteric infections. Unnecessary antibiotics can result in adverse events and contribute to the emergence of antimicrobial resistance. We assessed treatment practices among patients with laboratory-confirmed enteric infections in a regional healthcare system in Wisconsin, USA.
Methods
We used electronic health records to identify patients with laboratory-confirmed nontyphoidal Salmonella, Shigella, Shiga toxin-producing Escherichia coli (STEC), and Campylobacter infections during 2004–2017. Relevant clinical data, including diagnosis codes for chronic conditions and receipt of immunosuppressive medications and antibiotic prescriptions, were extracted. We defined appropriate treatment based on pathogen, patient characteristics, and practice guidelines for the study period.
Results
We identified 2064 patients infected with Campylobacter (1251; 61 %), Salmonella (564; 27 %), STEC (199; 10 %), or Shigella (50; 2 %). Overall, 425 (20 %) patients were immunocompromised, ranging from 17 % with Salmonella to 46 % with STEC. There were 220 (11 %) hospitalizations. Antibiotics were prescribed most frequently for Campylobacter (53 %), followed by Shigella (46 %) and Salmonella (44 %) infections. Among those prescribed antibiotics, prescriptions were appropriate for 71 % of Campylobacter, 100 % of Shigella, and 81 % of Salmonella infections. Antibiotics were prescribed for 24 % of STEC infections, despite recommendations against use. Guideline adherence generally decreased with age, except for Shigella infections, where adherence was highest for adults ≥ 50 years.
Conclusions
Antibiotic prescribing for laboratory-confirmed enteric infections was usually appropriate but did not follow practice guidelines in a substantial minority of cases, presenting opportunity for improvement. Antibiotic stewardship initiatives should address acute bacterial gastrointestinal infections in addition to other common infections.

Background
Streptococcus pneumoniae causes invasive pneumococcal disease (IPD) in adults. The introduction of pneumococcal conjugate vaccines (PCVs) has reduced vaccine serotypes but has also led to the rise of non-vaccine serotypes. The aim of this study was to analyse pneumococcal lineages and their association with recent changes in IPD among adults in Spain.
Methods
Data from adult IPD cases (≥18 years) were collected from six Spanish hospitals in 2019–2021. Strains were serotyped, tested for antibiotic susceptibility and subjected to whole genome sequencing (WGS). Findings were compared with data from previous periods (2008–2016).
Results
A total of 655 IPD episodes were examined. Pneumonia was the main focus (515/655), and 366 episodes occurred in adults over 64 years. Although IPD incidence decreased during COVID-19 pandemic, the burden of disease caused by PCV13 serotypes was significant. Notably, serotype 3 persisted (GPSC12-ST180 and GPSC83-ST260), and a new serotype 4 lineage emerged (GPSC162-ST13022). Among non-PCV13 serotypes, serotype 8 expanded (GPSC3-ST53) and a new serotype 12F lineage emerged (GPSC55-ST8060). Most serotypes presented a dominant Global Pneumococcal Sequencing Cluster (GPSC) like GPSC16-ST67 of 9N or GPSC19-ST433 of 22F. Nevertheless, some GPSCs were associated with several serotypes, the most numerous were GPSC3 (serotypes 8, 11A, and 33F) and GPSC6 (serotypes 11A and 14). The overall penicillin non-susceptibility rate was 17.0 %, 14.6 % resistance for meningitis and 1.6 % for pneumonia (15.1 % susceptible at increased exposure [SIE]). Serotypes 11A and 14 (GPSC6-ST156/6521) and 19A (GPSC1-ST320) had penicillin MICs above 1 mg/L. Acquired resistance genes associated with macrolide and/or tetracycline resistance were present in 19.4 % of isolates, particularly among serotypes 6C (GPSC47-ST386/4310) and 19A (GPSC1-ST320).
Conclusions
The burden of PCV13 serotypes in adult IPD remains significant, and serotype 3 is the primary contributor. However, the rise of stable lineages associated with non-PCV13 serotypes, particularly 8, 9N, and 22F highlights a shifting epidemiology. The persistence of multidrug-resistant lineages, such as GPSC6-ST156 and GPSC1-ST320, emphasizes the need for continued surveillance. Vaccination of high-risk adults with current and broader coverage PCVs would help to control the burden of pneumonia and IPD among adults.
背景:肺炎链球菌引起成人侵袭性肺炎球菌病(IPD)。肺炎球菌结合疫苗(PCVs)的引入减少了疫苗血清型,但也导致非疫苗血清型的增加。本研究的目的是分析西班牙成人肺炎球菌谱系及其与IPD近期变化的关系。方法:收集2019-2021年西班牙6家医院成人IPD病例(≥18岁)的数据。对菌株进行血清分型、抗生素敏感性检测和全基因组测序。研究结果与之前时期(2008-2016年)的数据进行了比较。结果:共检查了655例IPD发作。肺炎是主要焦点(515/655),在64岁以上的成年人中发生了366次发作。虽然IPD发病率在COVID-19大流行期间有所下降,但PCV13血清型引起的疾病负担仍显着。值得注意的是,血清3型持续存在(GPSC12-ST180和GPSC83-ST260),新的血清4型谱系出现(GPSC162-ST13022)。在非pcv13血清型中,血清8型扩大(GPSC3-ST53),新的血清12型 F谱系出现(GPSC55-ST8060)。大多数血清型呈现显性全球肺炎球菌测序集群(GPSC),如GPSC16-ST67的9 N或GPSC19-ST433的22 F。然而,一些GPSCs与几种血清型相关,最多的是GPSC3(血清型8、11 A和33 F)和GPSC6(血清型11 A和14)。总的青霉素不敏感率为17.0 %,脑膜炎耐药率为14.6 %,肺炎耐药率为1.6 %(暴露量增加时敏感率为15.1 % [SIE])。血清型11 A、14 (GPSC6-ST156/6521)和19 A (GPSC1-ST320)的青霉素mic均在1 mg/L以上。19.4% %的分离株存在与大环内酯和/或四环素耐药相关的获得性耐药基因,特别是在血清型6 C (GPSC47-ST386/4310)和19 A (GPSC1-ST320)中。结论:PCV13血清型在成人IPD中的负担仍然显著,其中血清3型是主要因素。然而,与非pcv13血清型相关的稳定谱系的增加,特别是8,9 N和22 F,突出了流行病学的变化。GPSC6-ST156和GPSC1-ST320等多药耐药谱系的持续存在,强调了继续监测的必要性。对目前和更广泛覆盖的pcv高危成人进行疫苗接种将有助于控制成人肺炎和IPD的负担。
