Influenza vaccine effectiveness against medically-attended influenza infection in 2023/24 season in Hangzhou, China. Hum Vaccin Immunother 2025; 21:2435156. [PMID: 39704470 DOI: 10.1080/21645515.2024.2435156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2024] [Revised: 11/17/2024] [Accepted: 11/24/2024] [Indexed: 12/21/2024] Open
Abstract
From 2020, influenza viruses circulation was largely affected by the global coronavirus disease (COVID-19) pandemic, notably leading to the extinction of the B/Yamagata lineage and raising questions about the relevance of the quadrivalent influenza vaccine, which includes this lineage. Evaluating vaccine effectiveness (VE) against influenza infections is important to inform future vaccine programs. A test-negative case-control study was conducted in five tertiary hospitals in Hangzhou, the capital city of Zhejiang province, China, enrolling medically-attended patients aged >6 months who presented with influenza-like illness (ILI) from October 1, 2023, to March 31, 2024. The VE was estimated using multivariate logistic regression models adjusted for sex, age, influenza detection methods, and influenza testing timing. Of the 157,291 medically-attended ILI participants enrolled 56,704 (36%) tested positive for influenza. Adjusted overall VE against any medically-attended influenza infection was 48% (95% Confidence interval [CI]: 46%-51%). The overall VE of the trivalent inactivated influenza vaccine (IIV3) was 59% (95% CI: 50%-66%), followed by the trivalent live attenuated vaccine (LAIV3) (VE = 53%, 95% CI: 42%-62%) and quadrivalent inactivated influenza vaccine (IIV4) (VE = 47%, 95% CI: 45%-50%). IIV3 provided even better protection against medically-attended influenza B infection than IIV4 (VE = 87%, 95% CI: 81%-92% for IIV3 versus VE = 53%, 95% CI: 50%-57% for IIV4). In the 2023/24 season in Hangzhou, China, the influenza vaccine offered moderate protection during a major epidemic. The results supported the World Health Organization recommendation to exclude the B/Yamagata lineage antigen in quadrivalent influenza vaccines in 2023.

Abstract
In the post-COVID-19 pandemic era, influenza virus infections continuously lead to a global disease burden. Evaluating vaccine effectiveness against influenza infection is crucial to inform vaccine design and vaccination strategy. In this study, we recruited 1120 patients with influenza-like illness (ILI) who attended fever clinics of 4 sentinel hospitals in the Ili Kazakh Autonomous Prefecture, Xinjiang Uygur Autonomous Region, China, from January 1 to April 7, 2024. Using a test-negative design, we estimated influenza vaccine effectiveness (VE) of 54.7% (95% CrI: 23.7, 73.1) against medical-attended influenza infection, with 62.3% (95% CrI: 29.3, 79.8) against influenza A, and 51.2% (95% CrI: 28.7, 83.0) against influenza B. Despite the moderate VE estimated in this study, influenza vaccination remains the most important approach to prevent influenza at the community level.

ZHONGHUA WEI CHANG WAI KE ZA ZHI = CHINESE JOURNAL OF GASTROINTESTINAL SURGERY 2024; 27:1261-1268. [PMID: 39710453 DOI: 10.3760/cma.j.cn441530-20240130-00050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Indexed: 12/24/2024]
Abstract
Objective: To investigate the short-term efficacy of robotic and laparoscopic surgery for treatment of mid-low rectal cancer. Methods: This was a retrospective cohort study of clinical data of patients with mid-low rectal cancer (caudad edge of tumor less than 10 cm from the anal verge) treated with laparoscopic or robotic radical surgery in the Northern Jiangsu People's Hospital Affiliated to Nanjing University from July 2019 to November 2021. Patients whose anus had not been completely preserved, with malignant obstruction or perforation, with poor anal function indicated by preoperative low anterior resection syndrome (LARS) scores, or with incomplete follow-up information were excluded. The inclusion criteria were met by 973 patients. After matching participants in a 1:2 propensity ratio with a caliper width of 0.02 standard deviations to reduce bias between patients caused by baseline imbalances, 175 patients were included in the robotic surgery group(RS) and 350 patients in the laparoscopic surgery group(LS). Baseline characteristics did not differ significantly between these two groups. The primary objectives were to compare oncological prognoses between the two groups, including disease-free survival (DFS), overall survival (OS), and anal function as assessed by the low anterior resection syndrome (LARS) scoring system, 6 months and 12 months postoperatively. Secondary outcomes included postoperative quality of life using the quality-of-life questionnaire C30 (QLQ-C30) and the QLQ-CR38 to establish a new scale, these being evaluated 6 and 12 months postoperatively. Higher functional module scores indicate better patient function, whereas lower symptom module scores indicate milder symptoms. Additionally, we compared the incidence of perioperative-related complications in the study patients. Results: (1) Oncological outcomes: The 2-year DFS and OS rates were 89.7% and 93.1%, respectively, for the robotic group and 86.0% and 91.7%, respectively, for the laparoscopic group. These differences are not statistically significant (P=0.230 for DFS, P=0.570 for OS). (2) Anal function: Among patients who had not undergone ileostomy, anal function was better in the robotic than in the laparoscopic group 6 months postoperatively (severe LARS: 9.8% [14/143] vs. 19.2% [56/292], χ2 = 6.712; P = 0.035). However, 12 months postoperatively, anal function did not differ significantly between the two groups. In patients with an ileostomy, anal function did not differ significantly between the two groups at 6 or 12 months postoperatively (both P > 0.05). (3) Postoperative quality-of-life: Compared with the laparoscopic group, the robotic group had better scores in the following aspects of quality of life: physical functioning (mean score 77.1±6.9 vs. 71.7±5.6, t =8.965, P=0.005), role in functioning (mean score 73.4±5.3 vs. 71.6±5.1, t = =3.851, P = 0.010), urinary tract complications (mean score 17.5±1.5 vs. 23.4±1.6, t = 41.40, P =0.001), and gastrointestinal symptoms (mean score 21.2±2.1 vs. 26.6±1.9, t = 29.40, P =0.001). These differences are all statistically significant (all P <0.05). By 12 months postoperatively, there were no statistically significant differences in functional or symptom modules of quality-of-life between the two groups (both P >0.05). (4) Perioperative complications: There was no statistically significant difference in intraoperative complications between the two groups (P > 0.05). The incidence of postoperative urinary retention was significantly higher in the laparoscopic than the robotic group (5.0% [19/350] vs. 1.7% [3/175], χ2 = 4.009, P = 0.044). Conclusion: In our study, robotic radical surgery for rectal cancer achieved short-term oncological outcomes similar to those achieved by laparoscopic radical surgery for rectal cancer. However, robotic radical surgery had advantages in terms of anal function and postoperative quality of life, while also reducing the incidence of perioperative urinary complications.

Comparing the protection of heterologous booster of inhaled Ad5-nCoV vaccine and hybrid immunity against Omicron BA.5 infection: a cohort study of hospital staff in China. BMC Infect Dis 2024; 24:1401. [PMID: 39695978 DOI: 10.1186/s12879-024-10250-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Accepted: 11/19/2024] [Indexed: 12/20/2024] Open
Abstract
BACKGROUND After the exit "zero-COVID" strategy in mainland China by the end of 2022, a large-scale COVID-19 outbreak seeded by Omicron variants occurred. An inhaled adenovirus type-5 vector-based (i.e., inhaled Ad5-nCoV) COVID-19 vaccine was licensed earlier in 2021. In this study, we aimed to assess the real-world effectiveness of a heterologous booster of inhaled Ad5-nCoV vaccine against Omicron infection and compared with the protection from hybrid immunity (i.e., prior breakthrough infection). METHODS In this retrospective cohort study, we identified 1087 out of a total of 1146 hospital staff from a tertiary hospital in Urumqi city, China from November 22 to December 29, 2022. Demographic characteristics, baseline health status, occupation, behavioral factors, laboratory test of serological IgG antibody, and timeline from immunization to laboratory-testing outcome were obtained. We analysed the individual-level vaccination status of inhaled Ad5-nCoV vaccine, prior SARS-CoV-2 infection status and baseline vaccination status, and other risk factors before follow-up. The protective effects of the heterologous inhaled Ad5-nCoV vaccine and hybrid immunity against Omicron BA.5 infection and hospitalization were calculated as relative rate reduction (RRR), which was estimated using multivariate Poisson regression models. RESULTS A total of 1087 hospital staff (median age of 34 years, and 343 males [31.6%]), including 931 accepted for serological antibody tests, were recruited to assess the vaccine effectiveness (VE) of the inhaled Ad5-nCoV booster and hybrid immunity. Among the 1087 participants, 413 had a history of prior SARS-CoV-2 infection (before follow-up) but did not receive an inhaled Ad5-nCoV booster, and 674 reported no prior infection, including 390 who received an inhaled Ad5-nCoV booster. The highest serological IgG antibody level was detected among the inhaled Ad5-nCoV group, with a median of 294.59 S/CO, followed by the hybrid immunity group, with a median of 93.65 S/CO compared to the reference level of the inactivated vaccine group (most of whom received the Sinopharm/BBIBP-CorV vaccine). The inhaled Ad5-nCoV booster and hybrid immunity yielded RRRs of 41.9% (95% CI: 24.8, 55.0) and 97.9% (95% CI: 94.2, 99.2), respectively, against Omicron BA.5 infection, regardless of symptom status. CONCLUSION We found that hybrid immunity could provide a high level of protection against Omicron infection, while a heterologous inhaled Ad5-nCoV booster conferred a moderate level of protection. Our findings supported the rollout of a heterologous vaccination strategy regardless of preexisting vaccine coverage.

PATIENT EDUCATION AND COUNSELING 2024; 129:108410. [PMID: 39217830 DOI: 10.1016/j.pec.2024.108410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 08/09/2024] [Accepted: 08/24/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVES This study aimed to investigate how doctor-patient communication, trust in doctors impacted patients' experience and satisfaction in shared decision-making (SDM). METHODS This study is based on the data from a cross-sectional survey (n = 12,401) conducted in 27 public specialist outpatient clinics in Hong Kong. RESULTS The multivariable regression models revealed that doctors' better communication skills were associated with lower decision-making involvement (odd ratio, 0.75 [95 % CI, 0.88-0.94], P < .001) but higher satisfaction with involvement (odd ratio, 6.88 [95 % CI, 5.99-7.93], P < .001). Similarly, longer consultation durations were associated with reduced involvement in decision-making (odd ratio, 0.71 [95 % CI, 0.66-0.73], P < .001) but increased satisfaction with involvement (odd ratio, 1.91 [95 % CI, 1.80-2.04], P < .001). Trust in doctors significantly mediated these associations, except for the association between consultation duration and patients' satisfaction with decision-making involvement. CONCLUSION Doctors' better communication skills and longer consultations might not necessarily increase patient involvement in SDM but correlated with increased satisfaction with involvement. Trust in doctors emerged as a mediator for participation and satisfaction in decision-making. PRACTICE IMPLICATIONS Clinics should consider patients' preferences and capabilities when tailoring communication strategies about decision-making and optimizing patient satisfaction.

COVID-19 vaccination modified the effect of nirmatrelvir-ritonavir on post-acute mortality and rehospitalization: a retrospective cohort study. Emerg Microbes Infect 2024; 13:2421397. [PMID: 39497519 PMCID: PMC11539398 DOI: 10.1080/22221751.2024.2421397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 09/27/2024] [Accepted: 10/21/2024] [Indexed: 11/08/2024]
Abstract
While previous research examined coronavirus disease 2019 (COVID-19) antiviral-vaccine interactions through exploratory subgroup analysis, none specifically designed for examining this interaction or its impact on post-acute outcomes. This study examined the interaction between nirmatrelvir-ritonavir and complete COVID-19 vaccination on reducing the risk of post-acute outcomes among COVID-19 patients. We followed COVID-19 patients hospitalized between 11 March 2022 and 10 October 2023, until 31 October 2023 in Hong Kong. Exposure groups were based on nirmatrelvir-ritonavir usage and vaccination status (fully or not fully vaccinated). Post-acute death and all-cause rehospitalization were the study outcomes. Propensity score weighting was applied to balance covariates among exposure groups, including age, sex, Charlson Comorbidity Index, and concomitant treatments. Multiplicative and additive interactions between nirmatrelvir-ritonavir and vaccination status were assessed. A total of 50,438 COVID-19 patients were included in this study and arranged into four exposure groups. Significant additive interaction on post-acute rehospitalization was observed (relative excess risk, 0.10; 95% CI, 0.02-0.19; p-value, 0.018; attributable proportion, 0.07; 95% CI, 0.01-0.12; p-value, 0.017; synergy index, 1.26; 95% CI, 1.02-1.55; p-value, 0.032). The interaction on post-acute mortality was marginally significant. In the subgroup analysis, the interaction effect is more pronounced in older adults, female, and CoronaVac recipients. In conclusion, our study demonstrated an additive interaction between nirmatrelvir-ritonavir and complete vaccination on post-acute outcomes, suggesting greater long-term benefits of the antiviral for fully vaccinated individuals compared to not fully vaccinated patients.

Long-term exposure to low-concentration sulfur dioxide and mental disorders in middle-aged and older urban adults. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 366:125402. [PMID: 39603322 DOI: 10.1016/j.envpol.2024.125402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2024] [Revised: 10/30/2024] [Accepted: 11/24/2024] [Indexed: 11/29/2024]
Abstract
The World Health Organization loosened the air quality guideline for daily sulfur dioxide (SO2) concentrations from 20 μg/m3 to 40 μg/m3. However, the guideline for SO2 concentrations in 2021 raised public concerns since there was no sufficient evidence that low-concentration SO2 exposure is harmless to the population's health, including mental health. We analyzed the associations between low-concentration SO2 exposure and incidence risks of total and cause-specific mental disorders, including depressive disorder, anxiety disorder, bipolar disorder, and schizophrenia spectrum disorder. 245,820 urban participants with low-concentration SO2 exposure (<8 μg/m3) at baseline were involved in the analyses from the UK Biobank. SO2 exposure (2006-2022) was estimated using high-resolution annual mean concentration maps from the Department for Environment, Food and Rural Affairs. Mental disorders and corresponding symptoms were identified using healthcare records and an online questionnaire, respectively. Associations were examined using both time-independent (2006-2010) and time-dependent (from 2006 to 2022) Cox regression models and logistic regression models with full adjustments for potential confounders. Stratification analyses were further conducted to identify vulnerable populations. Long-term exposure to low-concentration SO2 (per 1.36 μg/m3) was associated with increased risks of mental disorders, depressive disorder, and anxiety disorder with hazard ratios of 1.02 (95% confidence interval [CI]: 1.00, 1.03), 1.11 (95% CI: 1.07, 1.16), and 1.10 (95% CI: 1.06, 1.14) in the time-independent model, respectively. Associations were stronger for younger individuals. Additionally, the low-concentration SO2 exposure was linked to several psychiatric symptoms, such as trouble concentrating and restlessness, with odds ratios of 1.07 (95% CI: 1.04, 1.10) and 1.11 (95% CI: 1.07, 1.14), respectively. This study demonstrated significant associations of long-term exposure to low-concentration SO2 with mental disorders, highlighting the need for stricter regulations for SO2 to better protect public health and improve air quality in urban areas, in support of the Sustainable Development Goals.

Abstract
Objective: To investigate the curative effect and possible mechanism of rifaximin treatment on monocrotaline-induced hepatic sinusoidal obstruction syndrome (HSOS) in mice. Methods: Twenty-four male C57BL/6J mice were divided into three groups and treated with solvent control, monocrotaline, and rifaximin, respectively. The histopathological changes of the liver and intestine were observed by hematoxylin-eosin staining. The differences were compared in liver parameters, serum liver enzymes, inflammatory factors, apoptotic factors, gut microbiota, and gut tight junction proteins among three groups of mice. The inter-group comparison was conducted using a t-test and one-way analysis of variance. Results: The rifaximin-treated group had significantly improved liver histopathology. The serological levels of alanine aminotransferase and aspartate aminotransferase were (559.04±89.42) U/L and (676.90±106.25) U/L, respectively, which were significantly lower than those in the PA-HSOS model group [(846.05±148.46) U/L and (953.87±58.10) U/L, P<0.05], and were accompanied by lower levels of apoptotic cells and inflammatory factors. Additionally, the rifaximin-treated mice group gut microbiota had higher diversity compared with the PA-HSOS group (P<0.05), and the Shannon index was 7.77±0.10 and 7.16±0.07, respectively, indicating apparent differences in microbiota among different groups. The abundance of Firmicutes in the rifaximin group was 39.58%±0.56%, which was significantly higher than that in the model group (24.25%±0.64%, P<0.05), while the abundance of Bacteroidetes was 54.7%±0.41%, which was significantly lower than that in the model group (70.92%±0.49%, P<0.05). Simultaneously, the expressions of gut tight junction proteins ZO-1 and Occludin showed an upward trend and validated transcription levels compared to the model group following rifaximin intervention (P<0.05). Conclusion: Rifaximin can alleviate monocrotaline-induced hepatic sinusoidal obstruction syndrome in mice, and its mechanism may be via gut microbiota regulation, which in turn plays a role in improving intestinal barrier function.

Abstract
BACKGROUND Rare infectious diseases of poverty (rIDPs) involve more than hundreds of tropical diseases, which dominantly affect people living in impoverished and marginalized regions and fail to be prioritized in the global health agenda. The neglect of rIDPs could impede the progress toward sustainable development. This study aimed to estimate the disease burden of rIDPs in 2021, which would be pivotal for setting intervention priorities and mobilizing resources globally. METHODS Leveraging data from the Global Burden of Disease Study 2021, the study reported both numbers and age-standardized rates of prevalence, mortality, disability-adjusted life-years (DALYs), years lived with disability, and years of life lost of rIDPs with corresponding 95% uncertainty intervals (UIs) at global, regional, and national levels. The temporal trends between 1990 and 2021 were assessed by the joinpoint regression analysis. A Bayesian age-period-cohort model was used to project the disease burden for 2050. RESULTS In 2021, there were 103.76 million (95% UI: 102.13, 105.44 million) global population suffered from rIDPs with an age-standardized DALY rate of 58.44 per 100,000 population (95% UI: 42.92, 77.26 per 100,000 population). From 1990 to 2021, the age-standardized DALY rates showed an average annual percentage change of - 0.16% (95% confidence interval: - 0.22, - 0.11%). Higher age-standardized DALY rates were dominated in sub-Saharan Africa (126.35 per 100,000 population, 95% UI: 91.04, 161.73 per 100,000 population), South Asia (80.80 per 100,000 population, 95% UI: 57.31, 114.10 per 100,000 population), and countries with a low socio-demographic index. There was age heterogeneity in the DALY rates of rIDPs, with the population aged under 15 years being the most predominant. Females aged 15-49 years had four-times higher age-standardized DALY rates of rIDPs than males in the same age. The projections indicated a slight reduction in the disease burden of rIDPs by 2050. CONCLUSIONS There has been a slight reduction in the disease burden of rIDPs over the past three decades. Given that rIDPs mainly affect populations in impoverished regions, targeted health strategies and resource allocation are in great demand for these populations to further control rIDPs and end poverty in all its forms everywhere.

Abstract
BACKGROUND The effect of nirmatrelvir-ritonavir on post-COVID-19 outcomes for individuals who are immunocompromised is understudied. We aimed to examine the association of nirmatrelvir-ritonavir with post-acute sequelae and mortality among patients who are immunocompromised and admitted to hospital with COVID-19. METHODS We did a retrospective cohort study using territory-wide electronic health records from the Hong Kong Hospital Authority and Hong Kong Department of Health. Eligible patients were adults aged 18 years or older who tested positive for SARS-CoV-2 during the study period (March 11, 2022, to Nov 9, 2023) and were admitted to hospital with COVID-19. Four exposure groups were formed based on immune status (immunocompromised or immunocompetent) and nirmatrelvir-ritonavir status (yes or no). The primary outcome was post-acute inpatient death, starting from 21 days after the positive RT-PCR date. Standardised mortality ratio weighting with doubly robust adjustment was applied to control for confounders. Cox models were used to estimate hazard ratios (HRs) for the outcomes. FINDINGS Between March 11, 2022, and Nov 9, 2023, there were 89 772 individuals with positive RT-PCR tests, of whom 39 923 met eligibility criteria and were included in the study cohort. 19 914 (49·9%) of 39 923 patients were female, 20 009 (50·1%) were male and the median age was 75·0 years (IQR 63·0-85·0). 846 (38·2%) of 2217 patients who were immunocompromised and 14 586 (38·7%) of 37 706 patients who were immunocompetent were prescribed nirmatrelvir-ritonavir. Among the patients who were immunocompromised, those patients who received nirmatrelvir-ritonavir had significantly lower risk of post-acute inpatient death (HR 0·58, 95% CI 0·45-0·74; p<0·0001) and hospitalisation for acute respiratory distress syndrome (0·43, 0·20-0·90; p=0·024) than those who did not. A significant negative interaction was found between immune status and nirmatrelvir-ritonavir on post-acute all-cause hospitalisation (relative excess risk due to interaction -0·84, 95% CI -1·30 to -0·37; p=0·0004). INTERPRETATION Nirmatrelvir-ritonavir was associated with reduced risk of post-acute inpatient death among patients who were immunocompromised and admitted to hospital with COVID-19. However, the effectiveness of nirmatrelvir-ritonavir on post-acute hospitalisation outcomes was less pronounced in patients who were immunocompromised than in patients who were immunocompetent.

Abstract
Identifying epidemic-driving factors through epidemiological modeling is a crucial public health strategy that has substantial policy implications for control and prevention initiatives. In this study, we employ dynamic modeling to investigate the transmission dynamics of pneumonic plague epidemics in Hong Kong from 1902 to 1904. Through the integration of human, flea, and rodent populations, we analyze the long-term changing trends and identify the epidemic-driving factors that influence pneumonic plague outbreaks. We examine the dynamics of the model and derive epidemic metrics, such as reproduction numbers, that are used to assess the effectiveness of intervention. By fitting our model to historical pneumonic plague data, we accurately capture the incidence curves observed during the epidemic periods, which reveals some crucial insights into the dynamics of pneumonic plague transmission by identifying the epidemic driving factors and quantities such as the lifespan of flea vectors, the rate of rodent spread, as well as demographic parameters. We emphasize that effective control measures must be prioritized for the elimination of fleas and rodent vectors to mitigate future plague outbreaks. These findings underscore the significance of proactive intervention strategies in managing infectious diseases and informing public health policies.

Abstract
Whole slide imaging provides a wide field-of-view (FOV) across cross-sections of biopsy or surgery samples, significantly facilitating pathological analysis and clinical diagnosis. Such high-quality images that enable detailed visualization of cellular and tissue structures are essential for effective patient care and treatment planning. To obtain such high-quality images for pathology applications, there is a need for scanners with high spatial bandwidth products, free from aberrations, and without the requirement for z-scanning. Here we report a whole slide imaging system based on angular ptychographic imaging with a closed-form solution (WSI-APIC), which offers efficient, tens-of-gigapixels, large-FOV, aberration-free imaging. WSI-APIC utilizes oblique incoherent illumination for initial high-level segmentation, thereby bypassing unnecessary scanning of the background regions and enhancing image acquisition efficiency. A GPU-accelerated APIC algorithm analytically reconstructs phase images with effective digital aberration corrections and improved optical resolutions. Moreover, an auto-stitching technique based on scale-invariant feature transform ensures the seamless concatenation of whole slide phase images. In our experiment, WSI-APIC achieved an optical resolution of 772 nm using a 10×/0.25 NA objective lens and captures 80-gigapixel aberration-free phase images for a standard 76.2 mm × 25.4 mm microscopic slide.

Abstract
BACKGROUND Studies have established the short-term efficacy of nirmatrelvir-ritonavir in managing COVID-19, yet its effect on post-COVID-19 condition, especially in patients admitted to hospital, remains understudied. This study aimed to examine the effect of nirmatrelvir-ritonavir on post-COVID-19 condition among patients admitted to hospital in Hong Kong. METHODS This retrospective cohort study used real-world, territory-wide inpatient records, vaccination records, and confirmed COVID-19 case data from the Hong Kong Hospital Authority and Department of Health, The Government of the Hong Kong Special Administrative Region. Patients aged 18 years and older who tested positive for SARS-CoV-2 between March 11, 2022, and Oct 10, 2023, and who were admitted to hospital with COVID-19 were included. The treatment group included patients prescribed nirmatrelvir-ritonavir within 5 days of symptom onset, excluding those prescribed molnupiravir within 21 days, and the control group had no exposure to either nirmatrelvir-ritonavir or molnupiravir. The outcomes were post-acute inpatient death and 13 sequelae (congestive heart failure, atrial fibrillation, coronary artery disease, deep vein thrombosis, chronic pulmonary disease, acute respiratory distress syndrome, interstitial lung disease, seizure, anxiety, post-traumatic stress disorder, end-stage renal disease, acute kidney injury, and pancreatitis). These outcomes were evaluated starting at 21 days after the positive RT-PCR date in each respective cohort constructed for the outcome. Standardised mortality ratio weights were applied to balance covariates, and Cox proportional hazards regression was used to investigate the relationship between nirmatrelvir-ritonavir and outcomes. FINDINGS 136 973 patients were screened for inclusion, among whom 50 055 were eligible and included in the analysis (24 873 [49·7%] were female and 25 182 [50·3%] were male). 15 242 patients were prescribed nirmatrelvir-ritonavir during acute COVID-19 and 23 756 patients were included in the control group; 11 057 patients did not meet our definition for the exposed and unexposed groups. Patients were followed up for a median of 393 days (IQR 317-489). In the nirmatrelvir-ritonavir group compared with the control group, there was a significantly lower hazard of post-acute inpatient death (hazard ratio 0·62 [95% CI 0·57-0·68]; p<0·0001), congestive heart failure (0·70 [0·58-0·85]; p=0·0002), atrial fibrillation (0·63 [0·52-0·76]; p<0·0001), coronary artery disease (0·71 [0·59-0·85]; p=0·0002), chronic pulmonary disease (0·68 [0·54-0·86]; p=0·0011), acute respiratory distress syndrome (0·71 [0·58-0·86]; p=0·0007), interstitial lung disease (0·17 [0·04-0·75]; p=0·020), and end-stage renal disease (0·37 [0·18-0·74]; p=0·0049). There was no evidence indicating difference between the groups in deep vein thrombosis, seizure, anxiety, post-traumatic stress disorder, acute kidney injury, and pancreatitis. INTERPRETATION This study showed extended benefits of nirmatrelvir-ritonavir for reducing the risk of post-acute inpatient death as well as cardiovascular and respiratory complications among patients admitted to hospital with COVID-19. Further research is essential to uncover the underlying mechanisms responsible for these observed negative associations and to devise effective strategies for preventing the onset of post-acute sequelae.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 283:116753. [PMID: 39083872 DOI: 10.1016/j.ecoenv.2024.116753] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 07/15/2024] [Accepted: 07/16/2024] [Indexed: 08/02/2024]
Abstract
BACKGROUND Limited evidence exists regarding the association between ozone exposure and adverse sperm quality. We aimed to assess the association between ozone exposure and sperm quality, and identify susceptible exposure windows. METHODS We recruited 32,541 men aged between 22 and 65 years old attending an infertility clinic in Wuhan, Hubei Province, China from 2014 to 2020. Ozone data were obtained from a satellite-based spatiotemporal model. Generalized linear models were used to estimate the association between ozone exposure and sperm quality parameters, including sperm concentration, sperm count, sperm total motility, and sperm progressive motility during the entire stage of sperm development (0-90 days before ejaculation) and three crucial stages (0-9 days, 10-14 days and 70-90 days before ejaculation). Stratified analyses were performed to evaluate whether associations varied by age, body mass index, and education levels. RESULTS The final analysis included 27,854 adult men. A 10 μg/m3 increase in ozone concentrations during the entire stage of sperm development was associated with a -4.17 % (95 % CI: -4.78 %, -3.57 %) decrease in sperm concentration, -6.54 % (95 % CI: -8.03 %, -5.60 %) decrease in sperm count, -0.50 % (95 % CI: -0.66 %, -0.34 %) decrease in sperm total motility, and -0.07 % (95 % CI: -0.22 %, 0.09 %) decrease in sperm progressive motility. The associations were stronger during 70-90 days before ejaculation and among men with middle school and lower education for sperm concentration. CONCLUSIONS Ozone exposure was associated with decreased sperm quality among Chinese adult men attending an infertility clinic. These results suggest that ozone may be a risk factor contributing to decreased sperm quality in Chinese men.

Abstract
Screening for colorectal cancer (CRC) with colonoscopy has improved patient outcomes; however, it remains the third leading cause of cancer-related mortality, novel strategies to improve screening are needed. Here, we propose an optical biopsy technique based on spectroscopic optical coherence tomography (OCT). Depth resolved OCT images are analyzed as a function of wavelength to measure optical tissue properties and used as input to machine learning algorithms. Previously, we used this approach to analyze mouse colon polyps. Here, we extend the approach to examine human biopsied colonic epithelial tissue samples ex vivo. Optical properties are used as input to a novel deep learning architecture, producing accuracy of up to 97.9% in discriminating tissue type. SOCT parameters are used to create false colored en face OCT images and deep learning classifications are used to enable visual classification by tissue type. This study advances SOCT toward clinical utility for analysis of colonic epithelium.

Abstract
Existing evidence suggested that the risk of tuberculosis (TB) infection was associated to the variations in temperature and PM2.5. A total of 9,111 cases of TB were reported in Ningxia Hui Autonomous Region, China from 2013 to 2015 on a daily basis, and 57.2% of them were male. The TB risk was more prominent for a lower temperature in males (RR of 1.724, 95% CI: 1.241, 2.394), the aged over 64 years (RR of 2.241, 95% CI: 1.554, 3.231), and the high mobility occupation subpopulation (RR of 2.758, 95% CI: 1.745, 4.359). High concentration of PM2.5 showed a short-term effect and was only associated with an increased risk in the early stages of exposure for the female, and aged 36-64 years group. There were 15.06% (1370 cases) of cases of TB may be attributable to the temperature, and 2.94% (268 cases) may be attributable to the increase of PM2.5 exposures. Low temperatures may be associated with significantly increase in the risk of TB, and high PM2.5 concentrations have a short-term association on increasing the risk of TB. Strengthening the monitoring and regular prevention and control of high risk groups will provide scientific guidance to reduce the incidence of TB.

Abstract
Objective: To explore the gene mutation characteristics and the relationship between gene mutations and long-term prognosis in clinical stage ⅠA lung adenocarcinoma patients. Methods: A retrospective analysis was conducted on 63 clinical stage ⅠA lung adenocarcinoma patients who underwent surgical resection at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2007 to October 2012, with documented postoperative recurrence or metastasis, as well as those who had a follow-up duration of 10 years or more without recurrence or metastasis. Whole exome sequencing (WES) technology was used to analyze the gene mutation profiles in tumor tissues and univariate and multivariate Cox regression analysis were used to clarify the influencing factors for patient prognosis. Results: After long term follow-up, 13 out of the 63 patients (21%) experienced recurrence or metastasis. WES technology analysis revealed that the most common tumor related gene mutations occurred in epidermal growth factor receptor (EGFR), with a mutation rate of 65.1% (41/63), followed by tumor protein p53 (TP53), fatatypical cadherin 1 (FAT1), low density lipoprotein receptor-related protein 1B (LRP1B), mechanistic target of rapamycin (MTOR), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 4 (SMARCA4), with mutation rates of 30.2% (19/63), 20.6% (13/63), 15.9% (10/63), 15.9% (10/63), 15.9% (10/63), and 15.9% (10/63), respectively. Multivariate Cox regression analysis showed that PIK3CG mutations (HR=21.52, 95% CI: 3.19-145.01),smoothened (SMO) mutations (HR=35.28, 95% CI: 3.12-398.39), catenin beta 1 (CTNNB1) mutations (HR=332.86, 95% CI: 15.76-7 029.05), colony stimulating factor 1 receptor (CSF1R) mutations (HR=8 109.60, 95% CI: 114.19-575 955.17), and v-Raf murine sarcoma viral oncogene homolog B (BRAF) mutations (HR=23.65, 95% CI: 1.86-300.43) were independent risk factors affecting the prognosis of clinical stage ⅠA lung adenocarcinoma patients. Conclusions: PIK3CG, SMO, CTNNB1, CSF1R, BRAF gene mutations are closely related to long-term recurrence or metastasis in clinical stage ⅠA lung adenocarcinoma. Patients with these gene mutations should be given closer clinical attention.

Abstract
OBJECTIVE To investigate the effect of dihydroartemisinin (DHA) for enhancing the inhibitory effect of cisplatin (DDP) on DDP-resistant nasopharyngeal carcinoma cell line HNE1/DDP and explore the mechanism. METHODS CCK-8 method was used to assess the survival rate of HNE1/DDP cells treated with DHA (0, 5, 10, 20, 40, 80, and 160 μmol/L) and DDP (0, 4, 8, 16, 32, 64, 128 μmol/L) for 24 or 48 h, and the combination index of DHA and DDP was calculated using Compusyn software. HNE1/DDP cells treated with DHA, DDP, or their combination for 24 h were examined for cell viability, proliferation and colony formation ability using CCK-8, EdU and colony-forming assays. Flow cytometry was used to detect cell apoptosis and intracellular reactive oxygen species (ROS). The expression levels of apoptosis-related proteins cleaved PARP, cleaved caspase-9 and cleaved caspase-3 were detected by Western blotting. The effects of N-acetyl-cysteine (a ROS inhibitor) on proliferation and apoptosis of HNE1/DDP cells with combined treatment with DHA and DDP were analyzed. RESULTS Different concentrations of DHA and DDP alone both significantly inhibited the viability of HNE1/DDP cells. The combination index of DHA (5 μmol/L) combined with DDP (8, 16, 32, 64, 128 μmol/L) were all below 1. Compared with DHA or DDP alone, their combined treatment more potently decreased the cell viability, colony-forming ability and the number of EdU-positive cells, and significantly increased the apoptotic rate, intracellular ROS level, and the expression levels of cleaved PARP, cleaved caspase-9 and cleaved caspase-3 in HNE1/DDP cells. N-acetyl-cysteine pretreatment obviously attenuated the inhibitory effect on proliferation and apoptosis-inducing effect of DHA combined with DDP in HNE1/DDP cells (P<0.01). CONCLUSION DHA enhances the growth-inhibitory and apoptosis-inducing effect of DDP on HNE1/DDP cells possibly by promoting accumulation of intracellular ROS.

Abstract
Background Understanding the global burden of enteric infections is crucial for prioritizing control strategies for foodborne and waterborne diseases. This study aimed to assess the global burden of enteric infections in 2021 and identify risk factors from One Health aspects. Methods Leveraging the Global Burden of Disease (GBD) 2021 database, the incidence, disability-adjusted life years (DALYs), and deaths of enteric infections and the subtypes were estimated, including diarrheal diseases, typhoid and paratyphoid fever, invasive non-typhoidal Salmonella (iNTS) infections, and other intestinal infectious diseases. The estimates were quantified by absolute number, age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR) and age-standardized DALY rate with 95% uncertainty intervals (UIs). Thirteen pathogens and three risk factors associated with diarrheal diseases were analyzed. Results In 2021, the global age-standardized DALY rate of enteric infections was 1020.15 per 100,000 popultion (95% UI: 822.70-1259.39 per 100,000 population) with an estimated annual percentage change (EAPC) of -4.11% (95% confidence interval: -4.31% to -3.90%) in 1990-2021. A larger burden was observed in regions with lower Socio-demographic index (SDI) levels. Diarrheal disease was the most serious subtype with Western Sub-Saharan Africa exhibiting the highest age-standardized DALY rate (2769.81 per 100,000 population, 95% UI: 1976.80-3674.41 per 100,000 population). Children under 5 and adults over 65 years suffered more from diarrheal diseases with the former experiencing the highest global age-standardized DALY rate (9382.46 per 100,000 population, 95% UI: 6771.76-13,075.12 per 100,000 population). Rotavirus remained the leading cause of diarrheal diseases despite a cross-year decline in the observed age-standardized DALY rate. Unsafe water, sanitation, and handwashing contributed most to the disease burden. Conclusion The reduced burden of enteric infections suggested the effectiveness of previous control strategies; however, more efforts should be made in vulnerable regions and populations through a One Health approach.

Abstract
We developed spatially detailed source-impact estimates of population health burden measures of air pollution for the United States and Canada by quantifying sources-receptor relationships using the benefit-per-ton (BPT1) metric. We calculated BPTs as the valuations of premature mortality counts due to fine particulate matter (PM2.5; particulate matter ≤2.5 μm in aerodynamic diameter) exposure resulting from emissions of one ton of a given pollutant. Our BPT estimates, while accounting for a large portion of societal impact, do not include morbidity, acute exposure mortality, or chronic exposure mortality due to exposure to other pollutants such as ozone. The adjoint version of a widely used chemical transport model (CTM) allowed us to calculate location-specific BPTs at a high level of granularity for source-impact characterization. Location-specific BPTs provides a means for exploiting the disparities in source impact of emissions at different locations. For instance, estimated BPTs show that 20% of primary PM2.5 and ammonia emissions in the United States account for approximately 50% and 60% of the burden of each species, respectively, for an estimated burden of $370B USD. Similarly, 10% of the most harmful emissions of primary PM2.5 and ammonia emissions in Canada account for approximately 60% and 50% of their burden, respectively. By delineating differences and disparities in source impacts, adjoint-based BPT provides a direct means for prioritizing and targeting emissions that are most damaging. Sensitivity analyses evaluated the impact of our assumptions and study design on the estimated BPTs. The choice of concentration-response function had a substantial impact on the estimated BPTs and is likely to constitute the largest source of uncertainty in those estimates. Our method for constructing annual BPT estimates based on episodic simulations introduces low uncertainty, while uncertainties associated with the spatial resolution of the CTM were evaluated to be of medium importance. Finally, while recognizing that the use of BPTs entails an implied assumption of linearity, we show that BPTs for primary PM2.5 emissions are stable across different emission levels in North America. While BPTs for precursors of secondary inorganic aerosols showed sensitivity to emission levels in the past, we found that those have stabilized with lower emissions and pollutant concentrations in the North American atmosphere. We used BPTs to provide location-specific and sectoral estimates for the cobenefits of reducing carbon dioxide emissions from a range of combustion sources. Cobenefit estimates rely heavily on the emission characteristics of the sector and therefore exhibit more pronounced sectoral fingerprints than do BPTs. We provide cobenefit estimates for various subsectors of on-road transportation, thermal electricity generation, and off-road engines. Off-road engines and various heavy-duty diesel vehicles had the largest cobenefits, which in most urban locations far exceeded estimates of the social cost of carbon. Based on our cobenefit estimations, we also provide per-vehicle burden estimates for different vintages of vehicle subsectors such as transit buses and short-haul trucks in major US cities.

Abstract
Objective: To establish an absolute quantitative method for high ethanol-producing klebsiella pneumoniae in a viable non-culturable (VBNC) state. Methods: High ethanol-producing Klebsiella pneumonia was induced to enter the VBNC state and then the ethanol production was evaluated. A PMA-ddPCR method was established to count the copies of live cell genes in the VBNC state of high ethanol-producing Klebsiella pneumoniae using single-copy genes. Further, the sensitivity and adaptability of ddPCR for detecting low-concentration samples were evaluated in VBNC fecal simulation. Results: The lower detection limit of ddPCR for quantitative analysis of high ethanol-producing Klebsiella pneumoniae gradient diluent was 10 times that of qPCR. At low temperature and low nutritional state, high ethanol-producing Klebsiella pneumoniae entered the VBNC state on the 45th day. The quantitative results of PMA-ddPCR on VBNC state cells were (5.46±0.05) log10 DNA copies/ml. The ethanol production in the VBNC state was<2.2 mmol/L and the ability to produce ethanol was restored after recovery. The minimum detection limit for ddPCR in fecal simulated samples with VBNC state was 3.2 log10 DNA copies/ml. Conclusion: The ddPCR detection method for high ethanol-producing Klebsiella pneumoniae with VBNC state has good sensitivity and adaptability, and can be used for the detection of VBNC state cells in clinical samples.
