Abstract Interaction between severe acute respiratory coronavirus 2 (SARS-CoV-2) and IIEB remains under investigation. Objective: to compare IIEB incidence before and during COVID-19 pandemic, and assess incidence of coinfection with COVID-19 and case fatality. A cross-sectional study was performed on data from a centralized microbiology laboratory serving a network of healthcare centers comprising 713 pediatric and adult inpatient beds, expanded by 20% during the pandemic. Three periods were evaluated: (1) pre-pandemic: March 1, 2019-February 29, 2020; (2) pandemic year 1: March 1, 2020-February 28, 2021; (3) pandemic year 2: March 1, 2021-July 31, 2021. Descriptive statistical analysis was performed. 56502 samples (96% blood cultures) from 27224 patients were analyzed. Of these, 54 samples (from 54 patients) were positive for encapsulated bacteria. IIEB incidence was: 167.4, 32.6, and 50.4 per 100000 samples for periods 1, 2, and 3, respectively. Twelve IIEB episodes occurred during the pandemic period: 10 Streptococcus pneumoniae, and 2 Haemophilus influenzae, of which 7 were SARS-CoV-2/S. pneumoniae coinfections, with an incidence of 5.68 per 10000 COVID-19-related hospitalizations (0.056%). IIEB case fatality was 31%, 29%, and 60% for each period, respectively, 3/7 patients with coinfection died (43%). Case fatality for invasive pneumococcal disease (IPD) in patients without COVID-19, was 32.5%. Significant reduction in IIEB incidence was observed during the pandemic, coinciding with implementation of containment measures. The incidence of SARS-CoV-2/S. pneumoniae coinfection was low, with higher case fatality than IPD patients without COVID-19.
Resumen La interacción entre SARS-CoV-2 e infecciones invasivas por bacterias capsuladas (IIBC) continúa bajo estudio. Objetivos: comparar la incidencia de IIBC antes y durante la pandemia por COVID-19, evaluar la incidencia de coinfección con COVID-19 y la letalidad. Estudio transversal de registros de un laboratorio centralizado de Microbiología, que asiste a una red de centros asistenciales con 713 camas de internación para adultos y pediátricos, expandida 20% durante la pandemia. Tres periodos evaluados: 1) Pre-pandemia: 1-Marzo-2019 al 29-Febrero-2020; 2) Primer año de Pandemia: 1-Marzo-2020 al 28-Febrero-2021; 3) Pandemia 2021: 1-Marzo-2021 al 31-Julio-2021. Análisis estadístico descriptivo: Se analizaron 56.502 muestras (96% hemocultivos) correspondientes a 27.224 pacientes. De estas, 54 muestras (de 54 pacientes) fueron positivas para bacterias capsuladas. La incidencia de IIBC fue 167,4, 32,6 y 50,4 por cada 100.000 muestras para los periodos 1, 2 y 3, respectivamente. Doce IIBC ocurrieron durante la pandemia: 10 Streptococcus pneumoniae y dos Haemophilus influenzae, siete de ellos corresponden a coinfección SARS-CoV-2/S. pneumoniae, con una incidencia de 5,68 por cada 10.000 internaciones por COVID 19 (0,056%). La letalidad de las IIBC fue de 31, 29 y 60% para los tres periodos, respectivamente, 3/7 coinfectados fallecieron (43%). La letalidad por enfermedad neumocócica invasiva (ENI), sin COVID fue de 32,5%. Se evidenció una reducción significativa de la incidencia de IIBC luego del comienzo de la pandemia, coincidente con la implementación de las medidas sanitarias de contención de la pandemia. La incidencia de coinfección de SARS-CoV-2/S. pneumoniae fue baja y presentó mayor letalidad que las ENI sin COVID-19.
ABSTRACT
Introducción: el cáncer de mama es el tumor maligno más frecuente y la primera causa de muerte por cáncer en mujeres en Uruguay y en el mundo. La evidencia epidemiológica sugiere que el cáncer de mama en diferentes grupos de edades se comportaría como patologías distintas. El objetivo de este trabajo es caracterizar el cáncer de mama en Uruguay para diferentes estratos de edades. Material y método: se analizaron las tendencias temporales de la incidencia de cáncer de mama en mujeres en Uruguay en el período 2002-2019, y de la mortalidad por esta causa en 1990-2020. Para el quinquenio 2015-2019, se analiza además la distribución de estadios al diagnóstico y de perfiles biológicos (luminales, triple negativos y HER2 positivos). Se analizan tres segmentos de edades: mujeres de 20 a 44 años, de 45 a 69 y de 70 y más años. Resultados: las tasas de incidencia para el conjunto de edades se presentaron estables en el período 2002-2019, mientras que la mortalidad presenta una tendencia decreciente en el período 1990-2020. En las mujeres menores de 45 años se encuentra un aumento en la incidencia, con mortalidad que decrece hasta el 2010, seguido de una estabilización de las tasas; en las mujeres de 45 a 69 años la incidencia se mantiene estable y la mortalidad decrece; en las mayores de 70 años, la incidencia decrece mientras la mortalidad se mantiene estable. Más del 70% de los casos se diagnostican en estadios I y II. Los tumores luminales (receptores hormonales positivos, HER2 negativos) son el subtipo más frecuente para todos los grupos, la proporción de tumores con estas características aumenta con la edad, mientras decrece la proporción de HER2 positivo y triple negativo. Conclusión: en las mujeres uruguayas el cáncer de mama presenta características diferenciales para las tres franjas de edades analizadas.
Introduction: Breast cancer is the most common malignant tumor and the leading cause of cancer death in women in Uruguay and worldwide. Epidemiological evidence suggests that breast cancer in different age groups behaves as distinct pathologies. The objective of this work is to characterize breast cancer in Uruguay for different age groups. Method: Temporal trends in the incidence of breast cancer in women in Uruguay are analyzed for the period 2002-2019, along with mortality trends for this cause from 1990 to 2020. For the five-year period 2015-2019, the distribution of stages at diagnosis and biological profiles (Luminal, Triple-negative, and Her2 positive) is also analyzed. Three age segments are analyzed: women aged 20 to 44 years, 45 to 69 years, and 70 years and older. Results: The incidence rates for all age groups remained stable during the period 2002-2019, while mortality showed a decreasing trend in the period 1990-2020. In women under 45, there is an increase in incidence, with mortality decreasing until 2010, followed by a stabilization of rates; in women aged 45 to 69, incidence remains stable and mortality decreases; in those over 70, incidence decreases while mortality remains stable. More than 70% of cases are diagnosed at stages I and II. Luminal tumors (hormone receptor positive, Her2 negative) are the most frequent subtype for all age groups. The proportion of tumors with these characteristics increases with age, while the proportion of Her2 positive and triple-negative tumors decreases. Conclusions: In Uruguayan women, breast cancer presents differential characteristics for the three age groups analyzed.

Objective To investigate the changing trend and epidemiological characteristics of the incidence and mortality of chronic kidney disease (CKD) with age, period and birth cohort in Chinese population. Methods Based on the data of incidence and mortality of CKD in Chinese population aged 20-80 years from 1990 to 2019 in GHDx database, joinpoint regression model was used to analyze the incidence and mortality trend of CKD. An age-period-cohort model was constructed to analyze the effects of age, period, and birth cohort on the trend of CKD incidence and mortality. Results Joinpoint regression analysis showed that the standardized incidence rate of chronic kidney disease in Chinese population increased from 146.37/100 000 in 1990 to 161.52/100 000 in 2019, while the standardized mortality rate decreased from 12.98/100 000 in 1990 to 11.23/100 000 in 2019. The APC model analysis showed that the risk of CKD incidence and death in the Chinese population increased with age, while the risk of CKD incidence increased with the increase of period. The risk of death did not change significantly with the increase of period. The cohort born later had a lower risk of CKD incidence and death compared to the cohort born earlier. Conclusion At present, the age effect and period effect of the incidence and death risk of chronic kidney disease in China are dominant. It is important to take effective measures and intervene in a timely manner, especially to strengthen the protection of older high-risk groups born earlier.
ABSTRACT
Objective To analyze the data of prostate cancer in Wuhan from 2010 to 2019, understand the characteristics and trends of incidence, mortality, and YLL, and provide decision-making basis for Wuhan's cancer prevention and control strategies. Methods Data on deaths and incident cases of prostate cancer in Wuhan from 2010 to 2019 and from 2013 to 2017, respectively, were collected from the Wuhan Death Monitoring System. Indicators such as incidence rate, mortality rate, and years of life lost due to premature death (YLL) of prostate cancer in Wuhan were calculated using Excel 2016 and Python. The Bayesian Age-Period-Cohort Model (BAPC) was used to predict the mortality rate of prostate cancer in Wuhan from 2020 to 2024. The trend changes were described using the annual average percentage change (AAPC). Results From 2010 to 2019, the incidence, mortality, and YLL rates of prostate cancer in Wuhan showed an overall increasing trend (AAPC >0, P <0.05). The standardized mortality and incidence rates in the central urban area were significantly higher than those in the outer urban area, and the age group of 85 and above had the highest incidence and mortality rates. The age group of 0-54 had the largest increase in incidence and mortality rates. From 2020 to 2024, prostate cancer in Wuhan is expected to continue to increase slightly (an increase of 0.94%). Conclusion The incidence, mortality, and YLL rates of prostate cancer in Wuhan are showing an overall increasing trend, and this trend may continue. The characteristics are higher in the central urban area than in the outer urban area, and higher in the older age group than in the younger age group. Targeted measures need to be taken, and screening for high-risk populations should be strengthened.
ABSTRACT
Objective To investigate the in-hospital screening results of developmental dysplasia of the hip (DDH) in infants and young children in Ili area, and to analyze the risk factors affecting the occurrence of DDH. Methods According to the cluster sampling method 5 536 infants and young children who underwent DDH screening in the pediatric outpatient department and orthopedic outpatient department of our hospital from December 2019 to June 2022 were selected as the research objects. The children who met the diagnostic criteria of DDH were selected as the observation group (n=35), and 100 normal children were selected as the control group. Univariate and multivariate analysis were used to determine the independent risk factors affecting the occurrence of DDH in infants. Results Among the 39 cases were positive in primary screening, 35 cases were positive in secondary screening, and the positive rate was 6.32‰ . The results of single factor analysis showed that the proportion of women, second birth and above, caesarean section, breech delivery, family history, high altitude area, living environment room temperature °C, and leg binding when swaddling in the observation group was higher than that in the control group (P°C and leg binding in infants are related to the occurrence of DDH in infants, which can provide some reference for clinical screening, diagnosis and treatment.
ABSTRACT

ABSTRACT
Objective:To conduct comparative analysis of lung cancer incidence and mortality, as well as long-term trends in incidence and mortality rates and risk factors in China and the United States from 1990 to 2019 based on data from the Global Burden of Disease Study 2019 (GBD 2019) .Methods:The GBD 2019 database was used to extract new lung cancer cases, deaths, and age-standardized rate data for the analysis of lung cancer incidence and deaths in China and the United States based on different sex and age groups from 1990 to 2019. Joinpoint software was used to calculate and analyze annual percentage change (APC) and average annual percentage change (AAPC) of age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of lung cancer in China and the United States from 1990 to 2019, and to analyze the long-term trends. Risk factors associated with lung cancer mortality in China and the United States were analyzed using the disability-adjusted life years (DALYs) .Results:New cases of lung cancer in China increased from 257 000 cases in 1990 to 832 900 cases in 2019, and ASIR increased from 30.20/100 000 in 1990 to 41.71/100 000 in 2019; deaths increased from 256 300 cases in 1990 to 757 200 cases in 2019, and ASMR increased from 31.18/100 000 in 1990 to 38.70/100 000 in 2019. ASIR and ASMR for lung cancer in the United States showed a decreasing trend from 1990 to 2019, with ASIR decreasing from 58.87/100 000 in 1990 to 45.13/100 000 in 2019, and ASMR decreasing from 49.35/100 000 in 1990 to 36.11/100 000 in 2019. In terms of gender, the disease burden of lung cancer in Chinese males was higher than that of females in 1990 and 2019, with new cases of lung cancer in males rising from 179 000 in 1990 to 576 200 in 2019, and ASIR rising from 44.29/100 000 in 1990 to 61.74/100 000 in 2019, mortality rising from 177 900 in 1990 to 523 200 in 2019, and ASMR rising from 46.33/100 000 in 1990 to 58.10/100 000 in 2019. The number of new cases of lung cancer in Chinese females rose from 78 100 in 1990 to 256 700 in 2019, and ASIR rose from 18.01/100 000 in 1990 to 24.76/100 000 in 2019; the number of deaths rose from 78 400 in 1990 to 234 000 in 2019, and ASMR rose from 18.63/100 000 in 1990 to 22.86/100 000 in 2019. In 2019, lung cancer incidence rates for males and females in China and the United States showed an increasing and then decreasing trend with age, with incidence rates of lung cancer in Chinese males and females peaking in the age group of 85-89 years old; and in the United States, incidence rates of lung cancer in males peaked in the age group of 85-89 years old, and incidence rates of females peaked in the age group of 80-84 years old. In 2019, it was shown that mortality rate of lung cancer among males in China increased and then decreased with age, reaching a peak in the age group of 85-89 years old, and mortality rate of lung cancer among females increased with age, reaching a peak in the age group of ≥95 years old. In the United States, lung cancer mortality rate for males and females showed an increasing and then decreasing trend with age, peaking in the 85-89 and 80-84 age groups, respectively. Incidence and mortality rates were higher for males than females in all age groups in China and the United States in 1990 and 2019. The analysis results of Joinpoint software showed that ASIR and ASMR of lung cancer in China showed an overall increasing trend from 1990 to 2019, with an AAPC of 1.16% (95% CI: 0.93%-1.38%, P<0.001) for ASIR and 0.78% (95% CI: 0.56%-1.01%, P<0.001) for ASMR, with the most obviously increasing trend in ASIR and ASMR from 1997 to 2004, the APC were 2.84% and 2.58%, respectively. Lung cancer ASIR and ASMR in the United States population showed a decreasing trend, with an AAPC of -1.08% (95% CI: -1.20%-0.96%, P<0.001) for ASIR and -1.05% (95% CI: -1.24%--0.87%, P<0.001) for ASMR. In 1990 and 2019, the major mortality-related risk factor for lung cancer in China and the United States was smoking, and the major mortality-related risk factor for lung cancer in Chinese females was environmental particulate matter pollution. Conclusion:ASIR and ASMR of lung cancer in China show an increasing trend from 1990 to 2019, and ASIR and ASMR of lung cancer in the United States show a decreasing trend. In 2019, incidence rate of lung cancer in males and females in China show an increasing and then decreasing trend with age, mortality rate of lung cancer for males show an increasing and then decreasing trend with age, and mortality rate of lung cancer for females show an increasing trend with age. Lung cancer incidence and mortality rates for males and females in the United States in 2019 show an increasing and then decreasing trend with age. In both 1990 and 2019, incidence rates and mortality rates are higher for males than for females in all age groups in both China and the United States. Smoking is the major mortality-related risk factor for lung cancer in China and the United States, and environmental particulate matter pollution is the major mortality-related risk factor for lung cancer in Chinese females.

Objective To describe the incidence and mortality of brain tumors in China in 2020 and to predict the disease burden up to 2040.Methods The brain tumor incidence and mortality in 2020 were recorded based on the data from International Agency for Cancer Research(IARC),Cancer Today database.The incidence and mortality were standardized by age using Segi's world standard population.The burden of brain tumors in 2040 was predicted with assuming that national rates remained constant in 2020.Results It was estimated there were approximately 79 600 new brain tumors cases and 65 200 deaths in China in 2020.The age-standardized incidence and mortality rates of brain tumors in China were 4.1/100 000 and 3.2/100 000,respectively,which were lower than the United States of America,most of European countries and Australia.The incidence and mortality were higher than Africa,central America,and the Caribbean.From 2020 to 2040,the brain tumors cases and deaths are predicted to have an increase as 32.1%and 41.5%respectively.Conclusions The disease burden of brain tumors was still heavy in China.Further studies are urgently needed to clarify the epidemic trend of tissue typing and risk factors of brain tumors,which may support the development of effective prevention strategies.
ABSTRACT
Objective To analyze the burden and changing trend of testicular cancer in China from 1990 to 2019.Methods Based on the 2019 Global Burden of Disease Database(GBD 2019),analyze the incidence,mortality,disability-adjusted life years(DALYs),years of life lost(YLLs),years lived with disability(YLDs)and their variation trend of testicular cancer in Chinese population from 1990 to 2019.Evaluating changes in age standardized rate(ASR)by calculating annual estimated percentage change(EAPC).According to the age grouping,analyze the age distribution characteristics of testicular cancer disease burden by age group.Results In 2019,the incident cases,deaths,age-standardized incidence rate,and age-standardized mortality rate of testicular cancer in China were 17.17×103,1.21×103,2.39/105,and 0.16/105,respectively.Compared to 1990,incident cases,deaths,and age-standardized incidence rate increased obviously in China,which was consistent with the global change trend,while the increase was higher than the global level.However,both Chinese and global age-standardized mortality rate showed a downward trend.From 1990 to 2019,DALYs,YLLs and YLDs of testicular cancer increased by 29.66%,9.83%and 720.91%respectively in China.The two age groups,0-15 years group and 30-35 years group,were with highest incidence of testicular cancer,while the highest disease burden of testicular cancer was 30-35 years.Conclusion From 1990 to 2019,the disease burden of testicular cancer in China showed an upward trend.Adolescents and young adults should be the priority population for screening and prevention due to their higher incidence and disease burden.
ABSTRACT
BACKGROUND:Up to date,there is seldom research about the correlation between the harmonious alignment degree of lumbar lordosis and pelvic incidence and the improvement of postoperative clinical symptoms in patients with lumbar stenosis fusion. OBJECTIVE:To investigate the harmonious alignment degree of lumbar lordosis and pelvic incidence in patients with lumbar spinal stenosis and fusion,and compare the differences of spinal and pelvic sagittal parameters and clinical outcomes among different harmonious alignment degrees. METHODS:The medical records of 110 patients with lumbar spinal stenosis(48 males and 62 females,aged 57±11 years)who were treated with posterior lumbar laminar decompression and internal fixation in the Department of Spinal Surgery,Tianjin Union Medical Center from December 2019 to December 2021 were retrospectively analyzed.The postoperative follow-up was more than 1 year.According to the harmonious alignment degree of lumbar lordosis and pelvic incidence,they were divided into two groups:Group A(n=47)(pelvic incidence-lumbar lordosis>10°)and group B(n=63)(pelvic incidence-lumbar lordosis≤10°).The changes of clinical scores(low back pain visual analog scale score and Oswestry disability index)and spinal and pelvic sagittal parameters before and after surgery were compared between the two groups.The correlation between clinical symptom improvement and spinal and pelvic imaging parameters was analyzed. RESULTS AND CONCLUSION:(1)There were no significant differences in preoperative pelvic sagittal parameters and clinical function between the two groups(P>0.05).(2)There were no significant differences in operation time and blood loss between the two groups(P>0.05).(3)At the last postoperative follow-up,the visual analog scale score and Oswestry disability index in group B were significantly improved compared with group A(P=0.000,P=0.005).Lumbar lordosis and sacral slope were also significantly improved(P=0.000,P<0.05),and pelvic tilt was more significantly recovered(P=0.000).(4)Pearson correlation coefficient method results showed that the improvement of visual analog scale score of low back pain was significantly correlated with the improvement of pelvic tilt(r=0.209,P=0.008),lumbar lordosis(r=-0.133,P=0.021)and sacral slope(r=-0.156,P=0.031).Pelvic tilt was significantly correlated with Oswestry disability index(r=0.196,P=0.014).(5)It is concluded that reconstructed lumbar lordosis and reduced pelvic tilt for the harmonious alignment(pelvic incidence-lumbar lordosis≤10°)can effectively improve the clinical symptoms of patients.
ABSTRACT
Objective This study assesses the effect of 6S standard operation procedure(SOP)on the centralized man-agement of flexible endoscopes within a disinfection supply center.Methods A retrospective analysis was conducted on the cen-tralized management of 38 flexible endoscopes in the Disinfection and Supply Center of Foshan Maternal and Child Health Hospi-tal.From January to June 2022,the endoscopes were managed conventionally without the 6S SOP,as the routine group.From Ju-ly to December 2022,the endoscopes were managed with the 6S SOP,as the research group.The two groups were compared in terms of the adherence to cleaning and disinfection standards,pass rate of cleaning and disinfection,incidence of adverse events,and satisfaction degrees of healthcare providers.Results The research group under the 6S SOP management showed an signifi-cant improvement in the disinfection pass rate compared to the routine group,although the difference was not statistically signifi-cant.However,it presented a significant reduction in the incidence of adverse endoscopic events(P<0.05)and a significant in-crease in healthcare provider satisfaction(P<0.05).Conclusion The 6S SOP in the centralized management of flexible endo-scopes in the disinfection supply centers effectively enhances the quality of endoscope cleaning and disinfection,ensures their safe usage,and provides patients with efficient and secure care.
ABSTRACT
@#Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.
ABSTRACT
Objective@#To analyze the epidemiological and molecular characteristics of norovirus outbreaks in schools in Xicheng District of Beijing from 2017 to 2022, so as to provide evidence for the prevention and control of norovirus outbreaks in schools.@*Methods@#Data of norovirus outbreaks in schools in Xicheng District, Beijing during 2017 to 2022 were collected and analyzed by descriptive epidemiological methods. Realtime PCR was used to detect the nucleic acid of group GⅠand GⅡnorovirus, the positive norovirus nucleic acid samples were sent to Beijing Center for Disease Control and Prevention for molecular typing.@*Results@#From 2017 to 2022, 185 norovirus outbreaks were reported in schools in Xicheng District, including 166 cluster outbreaks and 19 outbreaks. A total of 2 044 cases were reported, with a total attack rate of 13.92%. There were two peaks in the outbreak time, which were from March to June after the spring semester and from October to December after autumn semester. Primary schools were the most common place of occurrence (101 cases), followed by nursery institutions (68 cases) and secondary schools (16 cases). There were statistically significant differences in the incidence rates among different sites(12.37%, 22.78%, 8.47%, χ2=263.34, P<0.01). There were significant differences in the incidence of vomiting, diarrhea, nausea and stomachache among different students (χ2=263.33, 90.58, 20.42, 30.29, P<0.01). Vomiting was the main symptom in primary school and nursery school children (96.41%, 98.28%), and the diarrhea rate was higher in middle school students (68.22%). The outbreaks were mainly caused by type GⅡ norovirus. The genotype from 2017 to 2021 showed the characteristics of diversity, mainly GⅡ.2[P16], but there was no significant advantage for the GⅡ.2 [P16] during 2019 to 2021.@*Conclusions@#The norovirus outbreak in schools in Xicheng district of Beijing from 2017 to 2022 are mainly caused by GⅡ type genome. The main genotype is GⅡ.2[P16]. Norovirus infection mainly occurred in primary schools and kindergartens. For the vulnerable populations, it is necessary to improve the capacity to early identification, student infectious disease management, active infection control and prevention measures, and pathogen surveillance and sporadic case monitoring.
ABSTRACT
@#Objective: On 4 March 2022, the first community-acquired case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported in Vanuatu, with community transmission occurring subsequently. It was expected that the number of notified SARS-CoV-2 cases would be an underestimate of the true infection rate of this outbreak; however, the magnitude of underreporting was unknown. The purpose of this study was to provide a population-based estimate of SARS-CoV-2 infection shortly after the first reports of community transmission, to understand the level of underdetection and undernotification in Vanuatu and thus to inform ongoing prevention and response activities. Methods: We conducted a cross-sectional SARS-CoV-2 prevalence study in two geographical administrative areas in Port Vila, Vanuatu in April 2022. All residents in selected areas were eligible. Trained teams conducted demographic and behavioural interviews and collected nasal specimens. Specimens were tested by polymerase chain reaction. The primary outcomes were the rates of SARS-CoV-2 attack (point prevalence) and cumulative attack, underdetection, notification and household secondary attack. Results: A total of 252 people from 84 households participated. Among 175 people who had a sample collected, 91 were SARS-CoV-2-positive (attack rate 52.0%). Most cases had not been detected before the study (underdetection rate 91.5%). More than half of previously detected cases were notified (notification rate 65.2%). Discussion: Within the first few weeks of community transmission, more than half of participants in the selected areas had evidence of SARS-CoV-2 infection; however, most infections had been undetected. This study provides important information about the rapid spread of novel infectious diseases in Vanuatu.
ABSTRACT
@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.
ABSTRACT
ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations, using COVID-19 infection as an example, and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai, with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects, and COVID-19 antigen test kits were distributed. From December 21, 2022 to September 30, 2023, prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects, comprising 6 098 males (47.3%) and 6 783 females (52.7%). The baseline survey revealed that 35.2% (4 540/12 881) of the subjects had a history of COVID-19 infection. During the follow-up period from December 21, 2022 to September 30, 2023, the average incidence density in the cohort was 0.61/person-year, with a higher incidence density in females (0.63/person-year) compared to males (0.59/person-year). Individuals aged 60 and above (0.64/person-year) and those with underlying health conditions (0.67/person-year) had a higher incidence density. Healthcare workers showed a notably higher incidence density (0.84/person-year) than that in other occupational groups. As of September 30, 2023, a total of 340 subjects in the cohort experienced secondary infections, with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance, providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.
