ABSTRACT
Background: Breastfeeding is an art and a skill which needs to be learnt and mastered. There is no one right position for breastfeeding. Any breastfeeding position that is comfortable for the mother and infant for effective breast milk transfer is an acceptable position. Cross cradle hold works well for Mothers who are breastfeeding for the first time, with latching difficulties, having flat and inverted nipples. Also, it helps in deep latching which helps to improve the level of attachment among new born. Objective of the study was to compare cross-cradle hold and other breastfeeding positions in terms of their effects on weight and length pattern in neonates among primiparous breastfeeding mothers after full-term vaginal delivery.Methods: This prospective cohort study was conducted in the obstetrics and gynaecology department among 240 primipara mothers who delivered vaginally at the same tertiary care institute.Results: Total 50.42% mothers preferred cross-cradle hold breastfeeding position. Neonates of mothers who had adopted cross-cradle hold, had better gain in weight and length after one month.Conclusions: Significantly more gain in weight and length of neonates were observed in those mothers who have adopted cross-cradle breastfeeding position.
ABSTRACT
Objective To investigate the effect of age on the incidence of cirrhosis and liver cancer in patients with chronic hepatitis B.Methods 279 patients with chronic hepatitis B were divided into the senior group and the younger group according to the age of the patients.The cumulative incidence of cirrhosis and liver cancer during 25 years of follow-up was calculated by using SPSS and R language through the long-term follow-up of HIS system,and the risk factors were analyzed by multivariate logistic regression.Results During follow-up,24 cases developed cirrhosis and 12 cases developed liver cancer.The cumulative incidence of liver cirrhosis was 1.5%,2.1%,5.4%,11.6%and 15.5%in the 5-year,10-year,15-year,20-year and 25-year group,and 5.5%,9.8%,22.9%,29.0%and 52.1%in the elderly,respectively.The difference between the younger age group and senior age group was statistically significant(P<0.001).A total of 2 risk factors(age and follow-up time)were included in the regression model.Two cases in the younger group developed into liver cancer after 17 and 21 years of follow-up,respectively.The cumulative incidence rates at 5,10,15,20 and 25 years were 1.8%,3.8%,18.5%,21.8%and 26.7%.A total of five factors(initial age,HBV-DNA load,HBV-DNA turned negative before the end-point,follow-up time,and sex)were included in the regression model.Conclusions The incidence of cirrhosis and liver cancer in CHB patients aged≥40 years,especially in male patients,is significantly higher than younger CHB patients.Timely initiation of antiviral therapy can delay disease progression and reduce the incidence of termi-nal liver disease.Whether antiviral therapy should be initiated for people aged 30 to 40 years remains to be studied.
ABSTRACT
Objective To investigate the associations between preconception dietary patterns(DPs)among Chinese women of childbearing age and neonatal birth weight.Methods The subjects selected for the questionnaire survey and follow-up were women of childbearing age who underwent prenatal eugenic examination at Jiang'an Maternal and Child Health Hospi-tal.Dietary intake information was collected using a semi-quantitative food frequency questionnaire,dietary patterns were extrac-ted by principal component analysis,and the relationship between DPs and birth weight was analyzed by modified Poisson re-gression or linear regression models.Results The final analysis of 221 maternal and infant pairs showed that women who fol-lowed the"nuts-poultry"pattern,one of the four dietary patterns,had a lower risk of delivering large for gestational age(LGA)infants(RR:0.25;95%CI:0.08-0.79),which was more pronounced in those who delivered male infants(RR:0.14;95%CI:0.03-0.72).Conclusion The risk of having LGA newborn is decreased in woman who takes a preconception dietary pattern characterized by nuts and poultry,which is more pronounced in those delivering male infants.Females of childbearing age should maintain good dietary habits before conception to ensure proper growth and development of the fetus and reduce the risk of ad-verse birth outcomes.
ABSTRACT
BACKGROUND:The number of hip fracture patients with dementia is increasing with an aging population,posing challenges for surgical treatment. OBJECTIVE:To determine the effect of dementia on postoperative complications in older patients with hip fractures. METHODS:Patients aged over 60 years old with hip fractures from 2000 to 2019 at Chinese PLA General Hospital were included.Dementia patients with a preexisting diagnosis of dementia at admission were identified.Each dementia patient was matched,for age±5 years,gender,and fracture type with 10 non-dementia patients.The differences in postoperative complications were compared between the two groups,including pneumonia,respiratory failure,gastrointestinal bleeding,urinary tract infection,surgical site infection,deep venous thrombosis,pulmonary embolism,angina pectoris,arrhythmia,heart failure,myocardial infarction,stroke,and death.The impact of dementia on major complications was evaluated using multivariate conditional logistic regression. RESULTS AND CONCLUSION:A total of 2 887 patients were included,of whom 125(4.3%)were dementia patients and matched with 1 243 non-dementia patients.The average age of dementia patients was(80.6±7.4)years;64.8%were female;53.6%were intertrochanteric fractures,and 46.4%were femoral neck fractures.Major complications occurred in 25(20.0%)patients with dementia and 123(9.9%)patients without dementia(P<0.01).The risk of major complications was 200.0 per 1 000 persons(95%CI,139.3-278.6)in dementia patients and 99.0 per 1 000 persons(95%CI,83.6-116.9)in non-dementia patients.Multivariate conditional logistic regression showed that a 2-fold risk of major postoperative complications after hip fracture surgery was found in dementia patients than in those without dementia(adjusted OR,2.11;95%CI,1.08-4.10).The results show that dementia is an independent risk factor for postoperative complications in elderly patients with hip fractures.Appropriate preoperative risk assessment and corresponding preventive and therapeutic measures should be given to this vulnerable population to mitigate postoperative complications.
ABSTRACT
Objective:To analyze the changes of fasting plasma glucose(FPG)level before and after menopause.Methods:Kailuan health checkup cohort was used to extract data of women aged≥18 years who participated in the first physical examination of Kailuan physical examination cohort and had menopausal age at the end of the seventh physical examination. A total of 3 749 women with 22 057 physical examination records were included in the analysis. Natural logarithmic transformation was applied to FPG, and a segmented linear mixed-effects model was used to analyze the changes in ln-transformed FPG before and after menopause. Additionally, an interaction analysis was performed to assess the multiplicative effect of baseline age and baseline body mass index(BMI)on ln-transformed FPG concerning pre- and post-menopausal periods.Results:The average age of the first physical examination for women in this study was (45.63±4.52)years, the median menopausal age was 51(50~53)years, and the median number of physical examinations was 6(5~7)times. The results of the piecewise linear mixed effect model showed that lnFPG increased from 1 year before menopause, with an average annual increase of 0.021 mmol/L, and continued to increase from menopause to 5 years after menopause, with an average annual increase of 0.007 mmol/L. LnFPG tended to be stable after 5 years of menopause. Baseline age could affect the changes of lnFPG before and after menopause, and there was a negative multiplicative interaction between baseline age ≥45 years and the time period from 6 years to 1 year before menopause( P=0.032). Women with baseline age ≥45 years had a higher average annual increase in lnFPG from 1 year before menopause to 5 years after menopause than women with baseline age <45 years( P<0.05). On lnFPG, there was a positive multiplicative interaction between baseline BMI and time segments around menopause. Compared to women with BMI <24.0 kg/m 2, obese women displayed more annual increase in lnFPG from 6 years to 1 year before menopause as well as from menopause to 5 years after menopause( P<0.05). Conclusions:Menopause has an adverse impact on FPG, with the most significant changes occurring within the period of one year before menopause and up to five years after menopause. Age and BMI significantly influence the changes in FPG before and after menopause.
ABSTRACT
Objective:To explore the difference between selective lobar bronchial block and main bronchial block in thoracoscopic surgery in children.Methods:A retrospective cohort study was conducted to analyze the clinical data of 150 children undergoing thoracoscopic surgery admitted to Henan Children's Hospital, Zhengzhou Children's Hospital, and Children's Hospital Affiliated to Zhengzhou University from December 2019 to December 2022. In the examination of the electronic medical record, 80 children were found to have selective lobar bronchial block, which was used as the study group, and 70 children were matched as the control group.Compare the general data of children in the two groups, such as age, gender, weight, surgical time, and other data. Compare the two groups with respect to hypoxemia, degree of pulmonary collapse, atelectasis, and number of bronchial blocker shifts. Compare the heart rate(HR), mean arterial pressure(MAP), degree of pulmonary collapse, and airway pressure(PAW) at different time points in the two groups[before single lung ventilation(OLV)(T1), 10 min after OLV(T2), and 10 min after OLV(T3)] Difference in alveolar arterial oxygen partial pressure(AaDO 2) levels. Results:Comparison of the incidence of hypoxemia, bronchial blocker displacement, and atelectasis in children in the study group were statistically significant( P<0.05). The results of repeated measurement of variance showed that there was statistically significant difference in the inter subject effects of HR and MAP levels at different time points between the two groups based on time factors( P<0.05). The results of repeated measurement of variance showed that there was statistical significance between the inter-subjective effects of the levels of PAW and AaDO 2 at different time points of the two groups with time factor as the source, group as the source, and intra-subjective effects with time and group interaction as the source( P<0.05). The levels of PAW and AaDO 2 in the study group at time points T2 and T3 were significantly lower than those in the control group, and the differences between the groups were statistically significant( P<0.05). Conclusion:The effect of selective lobobronchial blockade in thoracoscopic surgery in children is ideal, which can effectively improve the ventilation and related oxygenation of children, and reduce the occurrence of complications such as atelectasis and hypoxemia.
ABSTRACT
Background Lifestyle intervention or dietary modification has been the cornerstone of primary prevention and management of type 2 diabetes (T2D). Objective To investigate the associations of plant foods intake with the risk of incident T2D. Methods Based on a general population cohort, the Shanghai Suburban Adult Cohort and Biobank (SSACB), dietary data were collected for each participant in Songjiang District of Shanghai at enrollment with a validated Food Frequency Questionnaire (FFQ), and plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI) were calculated. Incident T2D cases were identified according to physician diagnosis (fasting blood glucose ≥7.0 mmol·L−1, or 2 h value during a 75-g oral glucose tolerance test ≥11.1 mmol·L−1, or glycosylated hemoglobin ≥6.5%, or with typical symptoms of hyperglycemia or hyperglycemic crisis, accompanied by a random plasma glucose ≥11.1 mmol·L−1) or medication records, obtained from the electronic information system for residents' medical insurance. Multivariable-adjusted Cox proportional hazards models and restricted cubic splines were used to evaluate the associations of foods from different sources with the risk of incident T2D. Results A total of 29016 participants [age at baseline (55.3±11.6) years] with a median follow-up duration of 5.688 years until 21 September 2022 were included. Plant foods (unprocessed) intake was associated with a decreased risk of incident T2D [HR (95%CI): 0.983 (0.969, 0.998)]. In comparison with participants in the highest quartile (≥859.3 g) of plant foods daily intake, the risk of incident T2D for those in the lowest quartile (<500.9 g) was higher [HR (95%CI): 1.250 (1.012, 1.544)]. No significant associations of animal foods [HR (95%CI): 1.006 (0.987, 1.026)] and processed foods [HR (95%CI): 0.978 (0.944, 1.014)] intakes were found with the risk of incident T2D. Replacing 50 g animal foods [HR (95%CI): 0.982 (0.968, 0.996)] or processed foods [HR (95%CI): 0.983 (0.969, 0.998)] with 50 g plant foods was associated with significantly decreased risks of incident T2D. Additionally, non-linear associations of PDI (Pnonlinear=0.023) and hPDI (Pnonlinear=0.016) with the risk of incident T2D were found in the SSACB. Conclusion Plant foods intake, especially healthful plant foods intake, is significantly associated with a decreased risk of incident T2D.
ABSTRACT
ObjectiveTo investigate the impact of yang deficiency syndrome on the progression to end-point events of diabetic kidney disease (DKD). MethodsA retrospective study among patients with stage Ⅳ DKD admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 1st, 2016 to September 30th, 2021 was conducted. Data on the patients' general information, clinical indicators including duration of diabetes, duration of proteinuria, history of smoking and drinking, hemoglobin (HGB), fasting blood glucose (FBG), albumin (ALB), serum creatinine (Scr), urea nitrogen (BUN), uric acid (UA), cholesterol (TC) , triglycerides (TG), low-density lipoprotein (LDL), 24-hour urine protein quantification (24h-UTP) and estimated glomerular filtration rate (eGFR), and TCM syndromes including symptoms, tongue and pulse, and syndrome scores were collected. The patients were divided into exposure group (yang-deficiency group) and non-exposure group (non-yang-deficiency group). The general information, clinical indicators and incidence rates of end-point events were compared, and the impact of yang deficiency syndrome on the end-point events of stage Ⅳ DKD was analyzed. Survival analysis was performed using Kaplan-Meier method, and multivariate Cox proportional risk models were used to identify independent predictors of end-point events. ResultsA total of 160 patients with stage Ⅳ DKD were included in the study, including 43 cases of yang deficiency syndrome and 117 cases of non-yang deficiency syndrome. Compared to those in the non-yang deficiency group, the waist circumference, BUN and the incidence of end-point events in the yang deficiency group were significantly higher (P<0.05 or P<0.01). Spearman correlation analysis showed that yang deficiency syndrome was positively correlated with incidence of end-point events of stage Ⅳ DKD (r = 0.167, P = 0.035). Furthermore, 24h-UTP and BUN levels were also positively correlated with end-point events in stage Ⅳ DKD patients (P<0.01), while ALB and HGB levels were negatively correlated (P<0.01). Kaplan-Meier survival curves showed that yang deficiency syndrome was associated with an increased risk of end-point events (Log Rank P = 0.011). Moreover, 24h-UTP levels ≥3500 mg, BUN level ≥8 mmol/L, ALB level <30 g and HGB level <11 g were all associated with the increase of the risk of end-point events (P<0.05 or P<0.01). Multivariate Cox regression analysis showed that yang deficiency syndrome was an independent risk factor for patients with stage Ⅳ DKD to progress into end-point events (HR = 2.36, 1.32 to 4.21; P = 0.004), as well as 24h-UTP ≥ 3500 mg, BUN ≥ 8 mmol/L, HGB<11 g and ALB<30 g (P<0.05 or P<0.01). ConclusionsFor stage Ⅳ DKD, patients with yang deficiency syndrome are more likely to have end-point events, which is an independent risk factor for the progression into end-point events.
ABSTRACT
ObjectiveTo evaluate the efficacy of TCM health management based on tertiary management system for patients with myocardial infarction (MI). MethodsA total of 277 patients with non-acute MI were enrolled and given comprehensive TCM health management strategies including health education, lifestyle adjustment, risk factors control, medication and TCM appropriate techniques management through a tertiary management system with "the patient as the core, village/community physicians as the main executive body, and tertiary TCM hospital specialists as the leading body", for a period of 12 months by using a prospective single-arm cohort study. Through patient reporting and medical records surveys, various indicators before and after 12-month management were collected and compared. The primary efficacy indicators were readmission rate and recurrent exacerbation rate, and the secondary efficacy indicators included disease awareness-related indicators, lifestyle behavior-related indicators, cardiovascular risk factor-related indicators and Canadian cardiovascular society (CCS) cardiac function classification. ResultsA total of 255 patients completed the study and were included in the final analysis. The recurrent exacerbation and readmission rates of patients after management were 23.14% (59 cases) and 20.25% (49 cases), respectively, significantly lower than 36.08% (92 cases) and 53.72% (130 cases) before management (P<0.05). Except for knowledge on diabetes diagnostic criteria with no significant difference before and after management (P>0.05), awareness of other knowledge with regard to the prevention and treatment of cardiovascular and cerebrovascular diseases were improved after management (P<0.01), as well as the total score (P<0.01). In terms of daily life behaviors, the rates of salty diet, sweet diet and greasy diet were significantly lower than baseline, while the rate of moderate exercise was significantly higher (P<0.05 or P<0.01); the rates of ongoing smoking and vigorous exercise were not significantly changed (P>0.05). For cardiovascular risk factors, patients' total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, fasting glucose, total depression assessment scale score, and total anxiety assessment scale score were significantly reduced after management (P<0.01). Systolic blood pressure and body mass index (BMI) were both higher after management (P<0.05 or P<0.01), and there was no statistically significant difference in diastolic blood pressure (P>0.05). In terms of the cardiovascular disease risk factors reaching the standard levels, the rate of LDL cholesterol <1.8 mmol/L significantly increased (P<0.01), while the rate of BMI <24 kg/m2 and the rate of systolic blood pressure <140 mmHg both decreased significantly (P<0.05 or P<0.01) from baseline; the diastolic blood pressure and rate of fasting glucose <7.0 mmol/L were not significantly changed (P>0.05). The patients' CCS cardiac function classification was significantly reduced (P<0.05). ConclusionTCM health management based on the tertiary management system can enhance MI patients' awareness of the disease, change poor lifestyle habits, reduce risk factors such as blood lipids and blood glucose, improve anxiety and depression, increase activity tolerance, and reduce their recurrence exacerbation and readmission rates, which is worthy of clinical promotion.
ABSTRACT
ObjectiveTo explore the research status and trends of cohort studies on traditional Chinese medicine (TCM) efficacy evaluation from 2017 to 2022 and provide ideas and references for research in this field. MethodsSix databases including Pubmed, Web of Science, Embase, Scopus, Cochrane Library and CNKI were searched from January 1st, 2017 to December 31st, 2022. The total number of annual publications, journals, highly cited literatures, and keywords were quantitatively and visually analyzed by Bibliometrix. ResultsA total of 328 articles were included, which were published in 141 journals. The number of articles published in this field showed an overall upward trend, and retrospective cohort studies (282 papers, 85.98%) accounted for the largest proportion. A total of 151 cohort studies (46.04%) were conducted based on the database and showed an overall upward trend. The subjects were mainly patients with tumors (77 papers, 23.48%), and cardiovascular and cerebrovascular diseases (64 papers, 19.51%). The top 3 highly cited literatures mainly explore the association between TCM and survival outcome and quality of life in patients with malignant tumors. Fourteen and twenty-five high-frequency keywords were included in Chinese and English literature respectively, which formed 3 clusters such as research methods, statistical analysis and diseases. ConclusionIt was the current status to focus on retrospective cohort studies and focus on patients with tumors or cardiovascular and cerebrovascular diseases. Using observational database to conduct cohort studies of TCM efficacy evaluation could be the future research direction.
ABSTRACT
ObjectiveTo retrospectively analyze the clinical efficacy of Xibining Ⅱ prescription in the treatment of knee osteoarthritis with cold-dampness blockage syndrome by oral medication and to explore the influencing factors of endpoint events. MethodA real-world retrospective cohort design was adopted, and medical records of knee osteoarthritis patients with cold-dampness blockage syndrome treated with oral medication from the orthopedics outpatient department of Jiangsu Province Hospital of Chinese Medicine were collected. All patients received conventional Western medicine treatment and were divided into non-exposure group (573 cases) and exposure group (427 cases) according to whether or not they received treatment with Xibining Ⅱ prescription. Descriptive analysis of the baseline data of the 1 000 screened cases was performed using IBM SPSS 27.0. According to the baseline data, 334 pairs were matched using the propensity score matching method, resulting in a total of 668 cases in both groups. The changes in visual analogous scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score, Japanese Knee Osteoarthritis Measure (JKOM) score, and traditional Chinese medicine (TCM) syndrome score before treatment and at 2, 6, 12 weeks after treatment, as well as the incidence of adverse reactions, were compared between the two groups. A multivariate logistic regression analysis was conducted to analyze the influencing factors of endpoint events, with clinical cure judged based on the improvement rate of WOMAC total score before and after treatment. ResultAfter 12 weeks of treatment, compared to the results before treatment, the VAS, WOMAC total score, JKOM score, and TCM syndrome score of patients in both groups significantly decreased (P<0.01). Compared to the non-exposure group, the exposure group showed a more significant reduction in VAS, WOMAC total score, JKOM score, and TCM syndrome score (P<0.01). After 12 weeks of treatment, the clinical cure rate and significant efficiency were higher in the exposure group than in the non-exposure group (P<0.05). Compared to the results before treatment within each group, VAS, WOMAC pain, stiffness, function scores, JKOM score, and TCM syndrome score significantly decreased at 2, 6, 12 weeks after treatment in both groups (P<0.01). Compared to the non-exposure group at the same time points, the exposure group showed a reduction in VAS at 2, 12 weeks, WOMAC pain at 6, 12 weeks, and function scores at 12 weeks (P<0.05, P<0.01). The JKOM score decreased at 6, 12 weeks, and the TCM syndrome score significantly decreased at 2, 6, 12 weeks in the exposure group (P<0.05, P<0.01). Multivariate logistic regression analysis at 12 weeks showed that factors affecting clinical cure included the course of disease, history of alcohol consumption, hypertension, coronary heart disease, and the use of Xibining Ⅱ prescription (P<0.05, P<0.01). Compared to the non-exposure group at the same time points, the incidence of epigastric discomfort in the exposure group was lower at 2, 12 weeks (P<0.01), the incidence of diarrhea and vomiting was slightly higher than that in the non-exposure group, but the difference was not statistically significant. ConclusionThe clinical application of Xibining Ⅱ prescription combined with conventional Western medicine treatment in the treatment of knee osteoarthritis with cold-dampness blockage syndrome is more effective than conventional Western medicine treatment alone. It can significantly reduce VAS, WOMAC total score, JKOM score, and TCM syndrome score, with more pronounced long-term effects and a low incidence of adverse reactions.
ABSTRACT
ObjectiveTo retrospectively analyze the effect of modified Shugan Dingji Decoction (疏肝定悸汤) on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation. MethodsA retrospective cohort study was conducted using the electronic medical record database of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st, 2018, to December 31th, 2021. The included patients were divided into an exposure group and a non-exposure group, each consisting of 100 cases, based on whether they received modified Shugan Dingji Decoction. General information of the patients including age, gender, body mass index, duration of illness and comorbidities, medication history, cardiac structure and function indicators such as left atrial diameter, left ventricular end-diastolic diameter, stroke volume and ejection fraction, and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recurrence of paroxysmal atrial fibrillation were collected. Kaplan-Meier (K-M) curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients. Univariate and multivariate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events. Additionally, a safety assessment was performed by comparing liver and kidney function indicators before and after treatment. ResultsIn the non-exposure group, a total of 49 cases (49.0%) experienced endpoint events, while in the exposure group, there were 26 cases (26.0%). The Log-rank test indicated significant difference between the two groups (χ2=11.211, P=0.001). Univariate Cox regression analysis showed that age, duration of illness, hypertension, diabetes, chronic heart failure, left atrial diameter, stroke volume, and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation (P<0.05 or P<0.01). Multivariate Cox regression analysis showed that the risk of endpoint events in the exposure group was significantly lower than that in the non-exposure group (P<0.01). Patients with a duration of illness >12 months had a significantly higher risk of endpoint events compared to those with a duration of illness ≤12 months (P<0.01). Patients without concomitant hypertension had a lower risk of endpoint events compared to those with hypertension (P<0.05). Patients with left atrial diameter >40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm (P<0.01). There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment (P>0.05). ConclusionThe use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation, which can help to reduce the recurrence and progression of atrial fibrillation. Long duration of illness, concomitant hypertension, and enlarged left atrial diameter are risk factors for patients to experience endpoint events.
ABSTRACT
Cohort studies play an important role in elucidating the association between risk factors and diseases, and are widely used in etiology research, the assessment of disease prognosis, understanding the natural history of diseases, and the surveillance following the market release of new drugs. The data produced by cohort studies possess great scientific value and can provide essential evidence for public health practice. A well-conceived scientific design is a prerequisite to conducting a cohort study, and the design should focus on aspects such as sample size, selection of exposed and non-exposed populations, follow-up procedures, outcome assessments, research duration, and the choice of analytical indicators and methods. Cohort studies have become an important way to obtain scientific evidence. Internationally renowned population-based cohorts, such as China Kadoorie biobank and the Framingham heart study cohort, have provided a wealth of scientifically valuable evidence for promoting human health. The quality of data produced by a cohort study is extremely important, and a cohort study should continuously incorporate new technologies and methods to provide objective, accurate, and reliable means to determine exposure and outcomes, as well as control for bias. Cohort studies have great potential for application and will continue to provide abundant high-quality scientific evidence for the development of strategies and measures to enhance human health.
ABSTRACT
@#Objective To examined gene mutations in thymic carcinoma (TC) patients and to explore prognostic correlates and potential targets for therapy. Methods We retrospectively included TC patients in Sichuan Cancer Hospital between January 2015 and Febuary 2021.Whole-exome sequencing was performed on tumor tissues from TC patients and their control peripheral blood samples, and the raw data were subjected to bioinformatics analysis and statistical analysis. Results We finally included 24 TC patients with 16 males and 8 females at a median age of 55 (42-74) years. The highest frequency of single nucleotide mutations in this cohort were in the TTN gene (42%), HSPG2 (29%), and OBSCN (29%). Higher frequency of copy number variations occurred in ZNF276 gene (54%, loss), BEND3 (50%, loss), DHODH (50%, loss), and VAC14 (50%, loss). Microsatellite instability (MSI) phenotype was found in 25% of the patients, and the mean tumor mutation burden (TMB) was 9.86. Conclusion This study is the first comprehensive analysis of the mutation profile of thymic carcinoma in China to date. The mutation frequencies of TTN, OBSCN, and ZNF276 genes were high. The biomarker analysis suggests that patients may benefit from immunotherapy and have a long effective survival.
ABSTRACT
Objective To conduct a retrospective cohort study on the influencing factors of poor prognosis of young and middle-aged patients with pulmonary tuberculosis. Methods Selecting 426 young and middle-aged patients who were diagnosed with pulmonary tuberculosis in our hospital from January to December 2018 as the research subjects. Collecting the social demography information of all patients and the information of potential factors affecting the prognosis (allergy history, smoking history, drinking history, BMI level, disease information, treatment information, etc.) and discussing the factors affecting the prognosis of young and middle-aged pulmonary tuberculosis patients and their effects. Results The average age of 426 patients was (41.93±5.17) years old, the average BMI of them was (21.97±3.15) kg/m2, and an average course of disease of them was (2.76±0.99) years. There was no significant difference in the basic sexual information between men and women. In this study, a total of 128 patients with poor prognosis were retrospectively followed up, including 90 males and 38 females. The detection rate of males was significantly higher than that of females (χ2=16.976, P2=18.850, P2=38.924, P2=127.207, P2=32.566, P2=16.715, P2=17.315, P2=16.976,P1 and P1 and P<0.05; Regular treatment still showed potential protective factors, with an HR of 0.408, P<0.05. Conclusion: Male, emaciated body type, disease course ≥ 5 years, smoking history, number of lung field lesions ≥ 3, presence of pulmonary cavities and comorbidities are potential risk factors, while regular treatment suggests potential protective factors. Conclusion More targeted disease control and management should be implemented for middle-aged and young patients with pulmonary tuberculosis based on the aforementioned influencing factors to improve their prognosis.
ABSTRACT
Objective To investigate the relationship between correcting abnormal glucose metabolism and mortality risk of malignant tumors of digestive system. Methods A retrospective cohort study was conducted. 1308 patients with abnormal glucose metabolism in our hospital from January 2019 were divided into exposed group (n=777) and non-exposed group (n=531) according to the presence or absence of glucose metabolism correction therapy. The patients were retrospectively followed up until December 2022. The incidence of digestive system tumors and the influencing factors of tumors were compared between the two groups. Results There were 31 patients with digestive system tumor and 9 patients died. The incidence of digestive system tumors was lower in the exposed group (3/777) than in the non-exposed group (28/531). The mortality rate in the exposed group (1/777) was lower than that in the non-exposed group (8/531). Cox regression model analysis showed that correcting abnormal glucose metabolism was a protective factor for the risk of death from malignant tumors of the digestive system in patients (HR value1, P<0.05). Conclusion Correcting abnormal glucose metabolism is of positive significance in reducing the risk of death from malignant tumors of digestive system. Patients with increased FBG, abnormal lipid metabolism, increased pulse pressure difference, family history of malignant tumors and alcohol consumption should pay special attention to correct abnormal glucose metabolism in time.
ABSTRACT
Background: The traditional Japanese style of soaking in a hot bath is a lifestyle custom for many citizens, no study had ever investigated the association between bathing as a lifestyle practice and the onset of long-term depression. Through a large-scale six-year longitudinal study, we aimed to determine whether tub bathing as a lifestyle custom plays a role in preventing the onset of long-term depression. Methods: Of 11,882 individuals who responded to surveys conducted in 2010 and 2016 as part of the Japan Gerontological Evaluation Study (the JAGES) project, we analyzed 6,452 and 6,465 individuals for whom information was available regarding summer bathing frequency and winter bathing frequency, respectively; all of these individuals were independent, had a Geriatric Depression Scale (hereafter, “GDS”) score of ≤4, and did not suffer from depression. The cohort study involved dividing participants into a group of those who bathed 0-6 times a week and a group of those who bathed ≥7 times a week and determining the percentages of individuals who developed depression based on their GDS scores six years later. Multiple logistic regression analysis was performed to determine odds ratios for the association between depression onset and tub bathing. Results: For individuals who tub bathed ≥7 times a week, the odds ratios for depression onset versus individuals who bathed 0-6 times a week in summer and winter were 0.84 (95% confidence interval, 0.64-1.10) and 0.76 (95% confidence interval, 0.59-0.98), respectively. Tub bathing ≥7 times a week in winter significantly reduced the risk of depression onset. Conclusions: New-onset depression was shown to be infrequent in older adults who bathe in a tub frequently. Tub bathing was suggested to potentially contribute to the prevention of depression in the elderly.
ABSTRACT
BACKGROUND AND AIM@#Remnant cholesterol (remnant-C) mediates the progression of major adverse cardiovascular events. It is unclear whether remnant-C, and particularly cumulative exposure to remnant-C, is associated with nonalcoholic fatty liver disease (NAFLD). This study aimed to explore whether remnant-C, not only baseline but cumulative exposure, can be used to independently evaluate the risk of NAFLD.@*METHODS@#This study included 1 cohort totaling 21,958 subjects without NAFLD at baseline who underwent at least 2 repeated health checkups and 1 sub-cohort totaling 2,649 subjects restricted to those individuals with at least 4 examinations and no history of NAFLD until Exam 3. Cumulative remnant-C was calculated as a timeweighted model for each examination multiplied by the time between the 2 examinations divided the whole duration. Cox regression models were performed to estimate the association between baseline and cumulative exposure to remnant-C and incident NAFLD.@*RESULTS@#After multivariable adjustment, compared with the quintile 1 of baseline remnant-C, individuals with higher quintiles demonstrated significantly higher risks for NAFLD (hazard ratio [HR] 1.48, 95%CI 1.31-1.67 for quintile 2; HR 2.07, 95%CI 1.85-2.33 for quintile 3; HR 2.55, 95%CI 2.27-2.88 for quintile 4). Similarly, high cumulative remnant-C quintiles were significantly associated with higher risks for NAFLD (HR 3.43, 95%CI 1.95-6.05 for quintile 2; HR 4.25, 95%CI 2.44-7.40 for quintile 3; HR 6.29, 95%CI 3.59-10.99 for quintile 4), compared with the quintile 1.@*CONCLUSION@#Elevated levels of baseline and cumulative remnant-C were independently associated with incident NAFLD. Monitoring immediate levels and longitudinal trends of remnant-C may need to be emphasized in adults as part of NAFLD prevention strategy.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3%,and that of non-infected group was 23.1%,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2%(95%CI:-2.3%-22.8%).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P>0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P>0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.
ABSTRACT
Objectives:To investigate the impact of baseline non-high-density lipoprotein cholesterol(non-HDL-C)levels on new-onset cardiovascular disease(CVD)in postmenopausal women. Methods:This prospective cohort study selected 8 893 postmenopausal women who participated from 2006 to 2018 employee health examination of Kailuan Group and had complete total cholesterol(TC)and HDL-C data and no history of CVD.Participants were followed up to 31 December,2021.The primary endpoint was the occurrence of CVD or death.According to the Chinese Lipid Management Guidelines(2023),the participants were divided into non-HDL-C<4.1 mmol/L group(n=6 079),4.1 mmol/L≤non-HDL-C<4.9 mmol/L group(n=1 824)and non-HDL-C≥4.9 mmol/L group(n=990).The cumulative incidence of CVD in different groups of non-HDL-C levels was calculated using the Kaplan-Meier method and tested by log-rank analysis.Multivariate Cox regression model was used to analyze the effects of different non-HDL-C levels on CVD. Results:The mean follow-up time was(10.78±4.48)years,the cumulative incidence of CVD in different non-HDL-C level groups was 1.82%,3.24%and 2.89%,respectively.Kaplan-Meier survival curve showed a statistically significant difference in cumulative incidence among the three groups(log-rank P<0.0001).The results of Cox regression analysis showed that after adjusting for confounding factors such as age and sex,the HR(95%CI)values for CVD in the 4.1≤non-HDL-C<4.9 mmol/L group and the non-HDL-C≥4.9 mmol/L group were 1.40(1.13-1.74)and 1.35(1.03-1.78),respectively. Conclusions:High non-HDL-C levels are an independent risk factor for new-onset CVD in postmenopausal women.
