Risultati per: Trattamento domiciliare di un paziente positivo al virus SARS-Cov-2

Circulation, Ahead of Print. BACKGROUND:Despite the significant global impact of the COVID-19 pandemic, limited studies have investigated the long-term cardiovascular sequelae of SARS-CoV-2 infection, particularly among Asian populations. This large-scale, population-based binational cohort study with long-term follow-up aimed to investigate the association between SARS-CoV-2 infection and the risk of cardiovascular events.METHODS:We used binational, large-scale, and population-based cohorts, including a Korean nationwide cohort (K-COV-N; discovery cohort; n=18 989 129) and a Japanese nationwide cohort (Japan Medical Data Center; validation cohort; n=12 218 680). Individuals aged 20 years or older were included from January 1, 2020, to December 31, 2022. We assessed the long-term risk of incident cardiovascular outcomes after SARS-CoV-2 infection. The primary outcome was the risk of cardiovascular diseases based onInternational Classification of Diseases, Tenth Revisioncode diagnosis. After propensity score–based overlap weighting, Cox proportional hazard models were used to estimate adjusted hazard ratios for cardiovascular outcomes. We assessed the time attenuation effect of cardiovascular outcomes after SARS-CoV-2 infection. Multiple subgroup analyses were conducted by 16 cardiovascular outcomes, COVID-19 severity, vaccination, and SARS-CoV-2 strain.RESULTS:In the overlap-weighted discovery cohort, 7 960 357 individuals were included (mean age, 48.52 years [SD, 9.33]; men, 4 283 878 [53.82%]). SARS-CoV-2 infection was associated with a long-term increased risk of overall cardiovascular outcomes (adjusted hazard ratio, 1.62 [95% CI, 1.60–1.64]), particularly ischemic heart disease (1.81 [95% CI, 1.77–1.84]), heart failure (1.79 [95% CI, 1.73–1.85]), cerebrovascular disorders (1.65 [95% CI, 1.60–1.69]), major adverse cardiovascular events (1.65 [95% CI, 1.60–1.70]), inflammatory heart diseases (1.53 [95% CI, 1.31–1.80]), dysrhythmia (1.44 [95% CI, 1.42–1.46]), and thrombotic disorders (1.42 [95% CI, 1.35–1.48]). The increased risk persisted up to 18 months, with the highest association observed for 1 to 6 months after infection. The risk of cardiovascular diseases was pronounced with COVID-19 severity; however, it decreased with the administration of complete vaccination and subsequent booster doses. A similar risk of cardiovascular outcomes existed across every SARS-CoV-2 era (pre-delta, delta, and omicron). Similar patterns were observed in the validation cohort. The absolute risk of cardiovascular disease events after SARS-CoV-2 infection remained remarkably low (2.12% versus 1.31% in the noninfected population), particularly stroke (0.24% versus 0.13%) and ischemic heart disease (0.73% versus 0.39%).CONCLUSIONS:This binational study observed associations between SARS-CoV-2 infection and cardiovascular events during extended follow-up across viral eras. Complete vaccination was linked to lower cardiovascular events. However, the absolute risk of cardiovascular disease events after SARS-CoV-2 infection remained remarkably low, particularly for stroke and ischemic heart disease. Although these findings suggest ongoing vigilance and preventive measures remain crucial, they should be interpreted within the context of these low absolute risks when considering long-term cardiovascular complications.

Introduction
The COVID-19 pandemic, driven by the SARS-CoV-2 virus, has had a significant global impact, with over 775 million cases reported and more than 7 million deaths as of July 2024. In Chile, approximately 5.4 million people have been infected, with a substantial proportion experiencing persistent symptoms known as post-COVID-19 syndrome. This study aims to estimate the prevalence of post-COVID-19 syndrome in Punta Arenas, Chile, and to explore the associated symptoms, mainly focusing on psychological, physical and molecular impacts on the affected population.

Methods and analysis
This cross-sectional study will use stratified random sampling to select a representative sample of 282 adults from Punta Arenas. Participants eligible for the study are those who had tested positive for SARS-CoV-2 by reverse transcription-quantitative PCR between July 2022 and July 2023. Data collection will include comprehensive clinical assessments, psychological evaluations and laboratory analyses of inflammatory biomarkers. Standardised instruments will be used to ensure consistency and reliability in measuring persistent symptoms. Statistical analyses will include descriptive statistics, regression models and subgroup analyses to identify risk factors and the prevalence of post-COVID-19 syndrome.

Ethics and dissemination
The Human Research Ethics Committee of the Clinical Hospital of the University of Chile approved the study protocol (Memorandum No 007/2023). We will present the results in peer-reviewed publications and national and international professional and academic meetings.

Objectives
This study evaluates the diagnostic value of the BNLF2b antibody, dual antibody testing and Epstein-Barr virus DNA (EBV-DNA) individually and in combination for nasopharyngeal carcinoma (NPC) detection.

Design
A prospective cohort study.

Setting
The study was conducted at Hunan Cancer Hospital, in a region in China with a high incidence of NPC, between January 2024 and June 2024.

Participants
A total of 350 patients with suspected NPC were enrolled based on clinical suspicion (eg, metastatic cervical lymph nodes or nasopharyngeal abnormalities with non-specific symptoms). The inclusion criteria included age ≥18 years, residency in Hunan Province, and provision of informed consent. The exclusion criteria included prior history of NPC or other head and neck malignancies, severe immunological/systemic diseases and inability to complete diagnostic evaluations.

Primary and secondary outcome measures
Demographic, clinical and biomarker data were collected, including BNLF2b antibody, EBV-DNA and dual antibody testing. Diagnostic performance metrics were calculated against histopathological confirmation as the gold standard. Follow-up assessments were conducted for non-NPC cases.

Results
Among 350 suspected NPC participants, 74 were diagnosed with NPC through biopsy. BNLF2b antibody exhibited the highest sensitivity (83.78%) and specificity (95.65%) among single biomarkers in NPC diagnosis, outperforming dual-antibody testing and EBV-DNA. Combining BNLF2b with dual-antibody testing improved specificity to 99.64%, although with reduced sensitivity (67.57%). NPC-diagnosed participants and those testing positive for BNLF2b or dual antibody biomarkers had a significantly higher prevalence of family history of NPC (p

Background
Governments used travel bans during the COVID-19 pandemic to limit the introduction of new variant of concern (VoC). In the Netherlands, direct flights from South Africa were banned from 26 November 2021 onwards to curb Omicron (B.1.1.529) importation.

Objectives
This study retrospectively evaluated the effect of the South African travel ban and the timing of its implementation on subsequent Omicron infections in the Netherlands and, in order to help inform future decision-making, assessed alternative scenarios in which the reproduction number (Re) and volume of indirectly imported cases were varied.

Design
Descriptive analysis and modelling study.

Outcome measure
Time (days) from 26 November 2021 to reach 10 000 cumulative Omicron infections in the Netherlands.

Methods
To benchmark the direct importation rate of Omicron from South Africa, we used the proportion (n/N, %) of passengers arriving on two direct flights from South Africa to the Netherlands on 26 November 2021 with a positive PCR sequencing result for Omicron VoC infection. We scaled the number of directly-imported Omicron infections before and after the travel ban to the incidence in South Africa. We assumed that 10% of all cases continued to arrive via indirect routes, a ‘failure rate’ of 2% (ie, incoming Dutch citizens not adhering to quarantine on arrival) and an effective reproduction number (Re) of Omicron of 1.3. In subsequent analyses, we varied, within plausible limits, the Re (1.1–2.0) and proportion of indirectly-imported cases (0–20%).

Results
Compared with no travel ban, the travel ban achieved a 14-day delay in reaching 10 000 Omicron cases, with an additional day of delay if initiated 2 days earlier. If all indirect importation had been prevented (eg, European-wide travel ban), a 21-day delay could have been achieved. The travel ban’s effect was negligible if Re was ≥2.0 and with a greater volume of ongoing importation.

Conclusions
Travel bans can delay the calendar timing of an outbreak but are substantially less effective for pathogens where importation cannot be fully controlled and tracing every imported case is unfeasible. When facing future disease outbreaks, we urge policy-makers to critically weigh up benefits against the known socioeconomic drawbacks of international travel restrictions.

Objective
A growing body of evidence points to a role for herpesviruses in the development of Alzheimer’s disease (AD) and a reduced risk of AD among patients receiving antiherpetic medications. We investigated the association between herpes simplex virus type 1 (HSV-1) and AD using real-world data (RWD) from USA.

Design
In a matched case–control study, patients with AD aged ≥50 years diagnosed between 2006 and 2021 were identified from the IQVIA PharMetrics Plus claims database. Controls were matched in a 1:1 ratio with subjects with AD on age, sex, region, database entry year and healthcare visit numbers.

Results
The study included 344 628 AD case–control pairs. History of HSV-1 diagnosis was present in 1507 (0.44%) patients with AD compared with 823 (0.24%) controls. HSV-1 diagnosis was found to be associated with AD (adjusted OR 1.80; 95% CI 1.65 to 1.96). Patients with HSV-1 who used antiherpetics were less likely to develop AD compared with those who did not use antiherpetics (adjusted HR 0.83, 95% CI 0.74 to 0.92).

Conclusions
Findings from this large RWD study implicate HSV-1 in the development of AD and highlight antiherpetic therapies as potentially protective for AD and related dementia.

Objective
To explore the association between perioperative SARS-CoV-2 infection and the postoperative complications during the breakout of the Omicron epidemic wave.

Design
Observational retrospective cohort study. Multivariable logistic regression was performed to explore the association between the duration from surgery to COVID-19 diagnosis and the likelihood of postoperative complications.

Setting
A general hospital in China.

Participants
7927 patients aged 18 years and older who underwent surgical treatment between 1 December 2022 and 28 February 2023.

Primary outcome measures
The outcome was a composite of postoperative adverse events that occurred within the initial 30 postoperative days.

Results
Of all patients, 420 (11.76%) experienced postoperative complications. Compared with No COVID-19, preoperative COVID-19 within 1 week (pre-1w) exhibited a high risk of postoperative complications (adjusted OR (aOR), 2.67; 95% CI 1.50 to 4.78), followed by patients with pre-2w (aOR, 2.14; 95% CI 1.20 to 3.80). For patients with postoperative COVID-19 within 1 week (post-1w), the aOR was 2.48 (95% CI 1.48 to 4.13), followed by patients with post-2w (aOR 1.95; 95% CI 1.10 to 3.45), and those with post-3w (aOR 2.25; 95% CI 1.27 to 3.98). The risks of postoperative complications decreased roughly with the increase of the time interval between the surgery date and SARS-CoV-2 infection. Stratification analyses suggested that perioperative COVID-19 increased the risk of postoperative complications in older patients, smokers, those with comorbidities or experiencing moderate or severe COVID-19 symptoms.

Conclusions
Our findings reveal a significant time-dependent relationship between perioperative COVID-19 and postoperative complications, highlighting the importance of tailored preoperative risk evaluations, enhanced postoperative surveillance, and the implementation of effective postoperative COVID-19 prevention measures.
