In August 2021, three students with diarrhea from the same school visited a local hospital in the S district of Beijing. An epidemic investigation showed that there were more students with diarrhea in the same school and they had one meal together. Campylobacter jejuni was isolated from both patients with diarrhea and asymptomatic food handlers; however, the latter also carried Campylobacter coli. Phylogenomic analysis showed that there was a campylobacteriosis outbreak among the students, and the asymptomatic food handler may have been the source of the infection. Routine inspection and surveillance for Campylobacter is needed for the food producing staff, particularly those cooking in the cafeteria in schools or other public food services.

Objective: To investigate the association between high sensitivity C-reactive protein (hsCRP) level and new-onset hypertension in different age groups. Methods: This was a prospective cohort study involving non-hypertensive population in Kailuan Group community who participated in health examination between 2006 and 2007.Follow-up was conducted every 2 years, and the time of new onset of hypertension was used as the endpoint of follow-up. The endtime of follow-up for patients without hypertension was the time of death or the last follow-up (December 31, 2017).According to the baseline hsCRP level, the participants were divided into low-risk group (hsCRP<1.0 mg/L), medium-risk group (hsCRP ≥1.0 and ≤3.0 mg/L), and high-risk group (hsCRP>3.0 mg/L), and further stratified by age. Kaplan-Meier method was used to calculate the cumulative incidence of hypertension in each group. Multivariate Cox regression model was used to analyze the association between hsCRP level and new-onset hypertension. Results: A total of 51 179 participants were included in this study, including 38 606 males (75.43%) with an average age of (48.1±12.2) years. The baseline hsCRP was 0.64 (0.25, 1.60) mg/L. The baseline hsCRP was 0.30 (0.16, 0.59), 1.57 (1.20, 2.10), 5.17 (3.80, 7.10) mg/L respectively in low-, medium- and high-risk groups. During the follow-up of (8.1±2.2) years, a total of 9 523 (18.60%) patients developed hypertension, and the cumulative incidence rates of low-, medium- and high-risk groups were 17.41%, 20.48% and 20.73%, respectively. The cumulative incidence of hypertension in low-, medium- and high-risk groups of<45, 45-54, 55-64, ≥65 years old were 13.53%, 15.82%, 16.76%; 19.27%, 22.84%, 21.62%; 21.55%, 24.19%, 24.88%;20.20%, 22.35%, 19.11%, respectively. Except for people aged ≥65 years, there were significant differences in the cumulative incidence of hypertension in low-, medium- and high-risk groups (all P<0.05).Multivariate Cox regression analysis showed that the risk of new-onset hypertension in the high risk group was 1.11 times higher than that in the low risk group (HR=1.11, 95%CI 1.05-1.18). The risk of new-onset hypertension in the high-risk group was 1.22 times (HR=1.22, 95%CI 1.08-1.38), 1.14 times (HR=1.14, 95%CI 1.04-1.26), 1.16 times (HR=1.16, 95%CI 1.04-1.30), and 1.02 times (HR=1.02, 95%CI 0.86-1.20) of the low-risk group, in the<45, 45-54, 55-64, and ≥65 years old groups, respectively. Conclusion: Higher hsCRP level is a risk factor for new-onset hypertension, and the risk of developing hypertension caused by elevated hsCRP is age-dependent.

OBJECTIVES: To investigate the sleep patterns and characteristics of infants and young children and the association between sleep patterns and breastfeeding. METHODS: A general information questionnaire, Brief Infant Sleep Questionnaire (BISQ), and a questionnaire on feeding were used to investigate the sleep quality and feeding patterns of 1 148 infants and young children aged 7-35 months. The K-means clustering method was used to identify sleep patterns and characteristics. A multivariate logistic regression analysis was used to investigate the association between sleep patterns and breastfeeding. RESULTS: Three typical sleep patterns were identified for the 1 148 infants and young children aged 7-35 months: early bedtime and long sleep time; short sleep latency and moderate sleep time; late bedtime, prolonged sleep latency, and insufficient sleep time. The third pattern showed sleep disorders. The multivariate logistic regression analysis showed that compared with formula feeding, exclusive breastfeeding within 6 months after birth reduced the risk of sleep disorder patterns by 69% (OR=0.31, 95%CI: 0.11-0.81). The risk of sleep disorder patterns was reduced by 40% (OR=0.60, 95%CI: 0.38-0.96) in the infants receiving breastfeeding for 4-6 months compared with those receiving breastfeeding for 1-3 months. CONCLUSIONS There are different sleep patterns in infants and young children, and breastfeeding can reduce the development of sleep disorder patterns.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective To investigate the prevalence and influencing factors of Enterobius vermicularis infections among children in Fanxian County, Henan Province in 2019, so as to provide insights into the management of enterobiasis. Methods Five kindergartens were selected in urban and rural areas of Fanxian County, Henan Province using the stratified sampling method in 2019, and a census of E. vermicularis infections was performed among all children in the kindergartens. E. vermicularis eggs were detected using adhesive and scotch cellophane-tape anal swab methods, and the basic characteristics of children and their families, health habits and the kindergartens’ information were investigated with questionnaires. Logistic regression analysis was used to investigate the risk factors and protective factors of pinworm infection in children. Results A total of 671 children were tested, and the mean prevalence of E. vermicularis infections was 15.50% (104/671). The prevalence of E. vermicularis infections was higher among children in rural kindergartens (28.13%, 72/256) than in urban kindergartens (7.71%, 32/415) (χ² = 50.380, P < 0.01), and greater in private kindergartens (32.26%, 60/186) than in public kindergartens (9.07%, 44/485) (χ² = 55.183, P < 0.01). There was no gender-specific prevalence of E. vermicularis infections among children (χ² = 1.442, P > 0.05), and the prevalence of E. vermicularis infections presented a tendency towards a rise with age (χ²_trend = 8.373, P < 0.05) and school grade (χ²_trend = 30.274, P < 0.05). Logistic regression analysis identified rural kindergartens and high grades as risk factors, and separate washing of children’s and adults’ cloths, frequent bathing and frequent dinnerware disinfection in kindergartens as protective factors for E. vermicularis infections among children. In addition, there was no significant difference in the detection of E. vermicularis infections among children by using adhesive (73.08%, 76/104) and scotch cellophane-tape anal swab methods (56.73%, 59/104) (χ² = 3.959, P > 0.05). Conclusions The prevalence of E. vermicularis infection is high among children in Fanxian Country, Henan Province. Health education and surveillance of enterobiasis are required to be intensified among children in rural kindergartens and senior grades and their parents and teachers.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Objective The purpose of this study was to investigate the correlation between single nucleotide polymorphisms (SNP) of Toll-like receptor 9 (TLR9) and tuberculosis in the Chinese Tibetan population . Methods A total of 613 active tubercu-losis patients and 603 healthy controls were enrolled in this case -control study.Two SNPs in TLR9 (rs187084 and rs5743836) were genotyped using the multiplex ligation detection reaction technique .The association of the SNPs with the susceptibility of TB was inves -tigated using logistic regression analysis . Results There was no statistically significant difference in the allele distribution of rs 187084 G/A between the TB patients and the healthy controls (P=0.668) or correlation between the genotype of rs 187084 and the genetic suscepti-bility of TB ( P >0.05).Dominant, recessive and additive models showed no association of this SNP with TB , either (P >0.05). Conclusion The rs187084 polymorphism of TLR9 is not correlated with the genetic susceptibility of tuberculosis in the Chinese Tibetan population.

Objectives: To compare the short-term and mid-term outcomes of elderly patients (>60 years old) with valvular heart disease (VHD) underwent bioprosthetic or mechanical valve replacement. Methods: Between January 2007 and December 2010, 559 elderly patients underwent valve replacement in Fuwai Hospital, clinical data of these patients were analyzed retrospectively (319 cases with bioprostheses vs 240 cases with mechanical prostheses). After matching, data from 192 cases in each group were compared. Results: The mortality within 30 postoperative days were similar (2.1% in both groups). All-cause death during follow up was also similar between the two groups (13.6% vs 13.7%, P=0.98). There was no statistically significant difference on the hospital readmission rate between the two groups (25.5% vs 35.9%, P=0.17). No significant difference was found on thromboembolic and hemorrhagic events free survival between the two groups (144 cases vs 138 cases, P=0.78). Conclusions: Short-term and mid-term survival and readmission rate are similar for the elderly VHD patients receiving bioprosthetic or mechanical valve replacement.

OBJECTIVETo investigate the prevalence of allergic diseases in children aged 0-24 months in the Wuhu urban area of Anhui Province and risk factors for allergic diseases.

METHODSCluster random sampling was performed to select 600 children aged 0-24 months and their mothers from the Wuhu urban area, and a questionnaire survey was conducted to collect the data of disease history, family history, mothers' conditions during pregnancy, and child-rearing situation. Univariate analysis and multivariate logistic regression analysis were performed for such data.

RESULTSAmong the 597 children included in the analysis, 56 (9.4%) were diagnosed with allergic diseases in the past. The univariate analysis showed that the age, use of antipyretic and analgesic drugs, a history of allergy in the father or grandparents, and the consumption of fish, shrimps, crabs, and shellfish during pregnancy were significantly associated with past allergic diseases (P<0.05). The multivariate logistic regression analysis showed that the age and a history of allergy in the father or grandparents were positively associated with past allergic diseases (OR=4.0-4.9, 2.7, and 2.4 respectively; P<0.05), while frequent consumption of fish, shrimps, crabs, and shellfish during pregnancy was negatively associated with past allergic diseases (OR=0.3; P<0.05).

CONCLUSIONSA family history of allergy is an independent risk factor for allergic diseases in children aged 0-24 months in the Wuhu urban area of Anhui Province, while frequent consumption of fish, shrimps, crabs, and shellfish during pregnancy is a protective factor.
