  • Application of Modified EcoScreen Condenser in Ventilated Patients for Collecting Exhaled Breath Condensate

    Objective To investigate the feasibility of collecting exhaled breath condensate ( EBC)fromartificially ventilated patients with modified EcoScreen condenser. Methods ①In vitro test with lung simulator: the modified EcoScreen condenser was connected to lung simulator and mechanically ventilated for 60 min through three different types of connected tube as follows: dry ventilator pipe disconnected to humidifier, connected to the unheated humidifier, and connected to heated humidifier.Meanwhile, the changes of the peak pressure of inspiration ( PI) and tidal volume ( VT ) were observed. The volume of condensate was measured at last. ②In vivo test from artificially ventilated patients: 10 patients were artificially ventilated and their EBCs were collected with the modified EcoScreen condenser through dry pipe disconnected to humidifier for 20 min. The changes of PI, VT , respiratory frequency( f) , heart rate( HR) , mean arterial blood pressure ( MAP) , and blood oxygen saturation ( SpO2 ) were observed. Results ①In vitro test with lung simulator: At the end of the ventilating through the dry pipe disconnected to humidifier for 60 min,2. 2 mL condensate wascollected. Neither the change of PI or VT nor the obstruction of the collecting tube by iced condensate were observed. The ventilating through dry pipe connected to unheated humidifier had to stop at 50 min as the obstruction of the collecting tube caused by ice. 5 mL condensate was collected. It was observed that VTdecreased and PI increased. After ventilation through dry pipe connected to heated humidifier for 60 min,10. 5 mL condensate was collected while PI slightly increased and VT decreased. ② In vivo test from artificially ventilated patients: After ventilation through dry pipe disconnected to humidifier for 20 min, 2 mL EBC was collected without significance changes in PI, VT, f, HR, MAP, and SpO2 . Conclusions The modified EcoScreen condenser can be favourably applied to artificially ventilated patients for collecting EBC.It is recommended to performfor 20 min through the pipe disconnected to humidifier to obtain sufficient EBC without condensate dilution and airway obstruction. It is warranted more attention to the clinical and mechanical monitoring in this procedure.

  • Analysis of nutritional risk in inpatients with chronic kidney disease

    ObjectiveTo explore the nutritional status of inpatients with chronic kidney disease (CKD) and analyze the factors affecting nutritional risk, to provide theoretical basis for further nutritional support.MethodsConvenience sampling method was adopted to select 719 inpatients with CKD as research subjects in a tertiary hospital in Chengdu, Sichuan Province from January to March 2018. Nutritional Risk Screening 2002 was used for nutritional risk screening, and chi-square test, t test, one-way analysis of variance, and multiple linear regression analysis were used to explore the influencing factors of nutritional risk.ResultsAmong the 719 cases, whose average nutritional risk score was 1.79±1.11, 158 cases had nutritional risk, accounting for 22.0%. There were statistically significant differences in nutritional risk score between patients of age<60 years and ≥60 years, between males and females, between patients with CKD stage 1-3 and stage 4-5, between patients with serum albumin level <30 g/L and ≥30 g/L, and between patients with and without anaemia (P<0.05). The results of multiple linear regression analysis showed that the nutritional risk score of CKD patients was negatively correlated to serum albumin level (P=0.016), positively correlated to age (P<0.001), and higher in females than that in males (P=0.001).ConclusionsInpatients with CKD have a higher nutritional risk, with age, gender and serum albumin as the main influencing factors. Based on the above factors, the medical staff should continue to take targeted intervention measures to assess the nutritional status of CKD inpatients early and conveniently, so as to provide scientific basis for further nutritional support and nutritional nursing.

  • Feasibility analysis of tuberculosis screening in diabetes mellitus patients in community

    Diabetes mellitus patients are usually at high risk of developing tuberculosis, the immune dysfunction caused by long-term high blood sugar, which can increase the susceptibility to tuberculosis. Severe tuberculosis could accelerate the course of diabetes mellitus and pose great difficulty to the clinical treatment. Therefore, early detection of potential tuberculosis patients in diabetes mellitus patients through tuberculosis screening and implementation of “three early” treatment can greatly improve the quality life of patients. This review summarizes the feasibility of tuberculosis screening in patients with diabetes mellitus, and to provide reference for the prevention and control of diabetes mellitus combined with tuberculosis.

  • Current status of participation rate in population-based colorectal cancer screening programs in China and its associated factors

    Colorectal cancer (CRC) screening is effective in reducing the burden of the disease. Participation rate is an important determinant of the magnitude of the effectiveness in population-based CRC screening. We summarize the current status of participation rate across the different organized CRC screening programs in China. The results indicate that the overall participation rates are low, and the acceptance of the screening protocols is poor in Chinese population. We conclude that the associated factors may include the poor health consciousness, low willingness-to-pay for screening, lack of personalized screening strategy and inadequate organization. Studies on the inventions to improve the willingness of screening and participation rate are of high demand and will provide important references in implementing large-scale CRC screening programs in China in the future.

  • Economic evaluation of liver cancer screening in China: a systematic review

    ObjectiveTo systematically review the status of economic evaluation of liver cancer screening in China, so as to provide reference for further studies.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data, CBM and VIP databases were searched to collect economic evaluation studies of liver cancer screening in China from inception to December, 2017. Two reviewers independently screened literature, extracted data and conducted descriptive analysis of basic characteristics, methods of economic evaluation and main results as well as quality and uniformity of reporting.ResultsA total of 5 studies were included. Among them, the starting age of screening were found to be 35 to 45 years old; α-fetoprotein (AFP) testing and ultrasound examination combined procedure and screening interval of every 6 months were mostly evaluated. The quality of the 5 studies was satisfactory, and the uniformity of reporting was relatively acceptable, with a median score of 78% (range: 60% ~ 78%). Two population-based studies reported cost per liver cancer detected (44 thousand and 575 thousand yuan). Three studies reported cost-effectiveness ratio(CER) based on life year saved (LYS) and quality adjusted life year (QALY). Among these results, only 1 study from mainland China reported CER based on LYS (1 775 yuan), and the calculated ratio of CER to local GDP per capita was estimated as 0.1, while 2 studies from Taiwan province reported 4 CERs, and the ratios of CER to local GDP per capita ranged from 1.0 to 2.2.ConclusionsInformation from liver cancer endemic areas such as Taiwan province indicates promising cost-effectiveness to conduct liver cancer screening in local general population, while data from mainland suggests that conducting liver cancer screening combining AFP and ultrasound in high-risk population will be cost-effective, however only supported by 1 regional study. This needs to be verified by further economic evaluations based on randomized controlled trials or cohort studies as well as health economic evaluations.

  • Research progress on type 2 diabetic retinopathy in adolescents

    The incidence of obesity and type 2 diabetes mellitus (T2DM) in adolescents has been rapidly increasing over the past two decades due to dramatic changes in dietary structure and physical activity. The incidence of diabetic retinopathy (DR), a serious vision-threatening complication of diabetes, is also increasing yearly in the adolescent population with T2DM. Due to the insidious onset of retinal diseases in the early stages, regular screening is important for the timely diagnosis of DR. However, there are still problems such as low attention of the population and insufficient screening rate. In the future, we should strengthen the health education of the adolescent population and optimize the control of risk factors such as blood glucose and blood pressure. At the same time, appropriate screening strategies should be actively developed, and the use of telemedicine and emerging technologies should be promoted for early detection of treatable lesions to improve patient prognosis.

  • Accuracy of screening tools for sarcopenia in the elderly in community: a network meta-analysis

    ObjectiveTo evaluate the diagnostic performance of different screening tools for sarcopenia in the community for the elderly with sarcopenia, and to provide evidence-based support for the accurate screening of elderly patients with sarcopenia. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CINAHL, VIP, CBM, and WanFang Data databases were searched by computer, and the relevant research on the diagnosis of sarcopenia in the elderly by publicly published risk screening tools was found. The retrieval time was from inception to June 2023. Two researchers independently screened the literature, extracted data, and evaluated the quality of the included studies, and then data analysis was performed by using Stata 15.1 and Meta Disc 1.4 software. ResultsA total of 24 studies were included, including 10 961 patients, involving 8 risk screening tools for sarcopenia in the elderly: leg circumference, MSRA-5, MSRA-7, upper arm circumference, ring test, Ishii score, SARC-CalF and SARC-F. Meta-analysis showed that the combined sensitivities of eight screening tools were 0.84 (95% CI 0.61 to 1.15), 0.82 (95% CI 0.48 to 1.38), 0.80 (95% CI 0.47 to 1.36) and 0.72 (95%CI 0.33 to 1.55), 0.67 (95%CI 0.37 to 1.21), 0.63 (95%CI 0.33 to 1.19), 0.49 (95%CI 0.38 to 0.63), 0.24 (95%CI 0.18 to 0.30), and the combined specificities were 0.39 (95%CI 0.18 to 0.82)、0.52 (95%CI 0.29 to 0.93)、0.54 (95%CI 0.29 to 1.03)、0.62 (95%CI 0.49 to 0.79)、0.63 (95%CI 0.50 to 0.78).The results of reticular meta-analysis showed that the surface under the cumulative ranking curve (SUCRA) of the eight screening tools ranked from high to low according to the cumulative sensitivity: calf circumference (67.4%) > MSRA-5 (65.3%) > MSRA-7 (64.1%) > upper arm circumference (54.5%) > ring test (46.5%) > Ishii score. The values of specificity SUCRA from highest to lowest were as follows: SARC-F (72.2%) > SARC-CALF (71.3%) > Ishii score (60.2%) > ring test (57.1%) > upper arm circumference (40.1%) > lower leg circumference (36.2%) > MSRA-5. ConclusionThe simple screening tool for common sarcopenia has high sensitivity and high specificity, so medical staff can give priority to the combination of the two screening tools, namely SARC-CalF. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.

  • Application effect analysis of artificial intelligence automatic diagnosis system for diabetic retinopathy in elderly diabetic patients in community and hospital

    ObjectiveTo study the efficiency and difference of the artificial intelligence (AI) system based on fundus-reading in community and hospital scenarios in screening/diagnosing diabetic retinopathy (DR) among aged population, and further evaluate its application value. MethodsA combination of retrospective and prospective study. The clinical data of 1 608 elderly patients with diabetes were continuously treated in Henan Eye Hospital & Henan Eye Institute from July 2018 to March 2021, were collected. Among them, there were 659 males and 949 females; median age was 64 years old. From December 2018 to April 2019, 496 elderly diabetes patients were prospectively recruited in the community. Among them, there were 202 males and 294 female; median age was 62 years old. An ophthalmologist or a trained endocrinologist performed a non-mydriatic fundus color photographic examination in both eyes, and a 45° frontal radiograph was taken with the central fovea as the central posterior pole. The AI system was developed based on the deep learning YOLO source code, AI system based on the deep learning algorithm was applied in final diagnosis reporting by the "AI+manual-check" method. The diagnosis of DR were classified into 0-4 stage. The 2-4 stage patients were classified into referral DR group. ResultsA total of 1 989 cases (94.5%, 1 989/2 104) were read by AI, of which 437 (88.1%, 437/496) and 1 552 (96.5%, 1 552/1 608) from the community and hospital, respectively. The reading rate of AI films from community sources was lower than that from hospital sources, and the difference was statistically significant (χ2=51.612, P<0.001). The main reasons for poor image quality in the community were small pupil (47.1%, 24/51), cataract (19.6%, 10/51), and cataract combined with small pupil (21.6%, 11/51). The total negative rate of DR was 62.4% (1 241/1 989); among them, the community and hospital sources were 84.2% and 56.3%, respectively, and the AI diagnosis negative rate of community source was higher than that of hospital, and the difference was statistically significant (χ2=113.108, P<0.001). AI diagnosis required referral to DR 20.2% (401/1 989). Among them, community and hospital sources were 6.4% and 24.0%, respectively. The rate of referral for DR for AI diagnosis from community sources was lower than that of hospitals, and the difference was statistically significant (χ2=65.655, P<0.001). There was a statistically significant difference in the composition ratio of patients with different stages of DR diagnosed by AI from different sources (χ2=13.435, P=0.001). Among them, community-derived patients were mainly DR without referral (52.2%, 36/69); hospital-derived patients were mainly DR requiring referral (54.9%, 373/679), and the detection rate of treated DR was higher (14.3%). The first rank of the order of the fundus lesions number automatically identified by AI was drusen (68.4%) and intraretinal hemorrhage (48.5%) in the communities and hospitals respectively. Conclusions It is more suitable for early and negative DR screening for its high non-referral DR detection rate in the community. Whilst referral DR were mainly found in hospital scenario.

  • Research Progress of Lung Cancer Screening

    Currently,lung cancer (LC) has one of the highest incidence rates among various malignant tumors worldwide,and the annual mortality rate of LC has ranked first among all malignant tumors. About 80% of LC patients present to the hospital in a late advanced stage and lose the chance of surgical resection. Among all the patients who receive surgical treatment,the 5-year mortality rate of patients with early TNM stages is far lower than that of patients with advanced stage LC. With the advancement of medical equipment and more people who receive routine medical examination,more and more patients with small pulmonary nodules are discovered. Limited lung resection,including wedge resection and segmental resection,can be performed with minimally invasive video-assisted thoracoscopic surgery for these patients to acquire equivalent surgical outcomes as traditional lobectomy and a much better postoperative quality of life. LC screening increases the chances of early detection and diagnosis of LC patients,so these patients can receive reasonable diagnosis and treatment at an early stage. This strategy can greatly reduce treatment cost and mortality,and achieve maximal treatment benefits with minimal economic and medical cost. This review focuses on the necessity,high-risk groups,evaluation criteria and methods of LC screening with some LC screening guidelines and research studies in order to provide reasonable and feasible screening strategies and references for clinical LC screening.
