Incidence and mortality rate of esophageal cancer has decreased during past 40 years in Hebei Province,China

Background： Hebei province is located in North of China with of approximately 6% of whole national population. It is known as a high-risk area for esophageal cancer in China and worldwide. The aim of our study was to estimate the esophageal cancer burden and trend in Hebei Province. Methods： Eight cancer registries in Hebei Province submitted cancer registry data to the Hebei Provincial Cancer Registry Center. All data were qualified and compiled for cancer statistics in 2011. The pooled data were stratified by gender and age group （0, 1-4, 5-9, 10-14...80＋）. Incidence and mortality rates were age-standardized to World Segi＇s population standard and expressed per 100,000 persons. In addition, proportions and cumulative incidence/mortality rates for esophageal cancer were calculated. Esophageal cancer mortality data during the periods 1973-1975, 1990-1992, and 2004-2005 were extracted from the national death surveys. Mortality and incidence rate data from Cixian and Shexian were obtained from population-based cancer registries in each county. Results： The estimated number of newly diagnosed esophageal cancer cases and deaths in 2011 in Hebei Province was 24,318 and 18,226, respectively. The crude incidence rate of esophageal cancer was 33.37/100,000 （males, 42.18/100,000 and females, 24.31/100,000）. The age-standardized rate by world standard population （ASRW） was 28.09/100,000, ranking third among all cancers. The esophageal cancer mortality rate was 25.01/100,000 （males, 31.40/100,000 and females, 18.45/100,000）, ranking third in deaths among all cancers. The mortality rates of esophageal cancer displayed a significant decreasing trend in Hebei Province from 1973-1975 （ASRW =48.69/100,000） to 2004-2005 （ASRW =28.02/100,000）, with a decreased rate of 42.45%. In Cixian, the incidence of esophageal cancer decreased from 250.76/100,000 to 106.74/100,000 in males and from 153.86/100,000 to 75.41/100,000 in females, with annual percentage changes （APC） of 2.13 and 2.16, while the mortality rates declined with an APC of 2.46 for males and 3.10 for females from 1988 to 2011. In Shexian, the incidence rate decreased from 116.90/100,000 to 74.12/100,000 in males and from 46.98/100,000 to 40.64/100,000 in females, while the mortality rates declined, with an APC of 4.89 in males from 2003 to 2011. Conclusions： Although the incidence and mortality rates of esophageal cancer remain high, an obvious decreasing trend has been observed in Hebei Province, as well as in high-risk regions, such as Cixian and Shexian, over the past 40 years.

Modified shock index and mortality rate of emergency patients

BACKGROUND:This study aimed to determine whether modified shock index(MSI)is associated with mortality that is superior to heart rate,blood pressure,or the shock index(SI).in emergency patients.METHODS:A retrospective database review was performed on 22 161 patients who presented to Peking Union Medical College Hospital Emergency Department and received intravenous fluids from January 1 to December 31,2009.We gathered data of the patients on age,gender,vital signs,levels of consciousness,presenting complaints,and SI and MSI were calculated for all patients.RESULTS:Multivariate regression analysis was performed to determine the correlation between risk factors and outcome.There is a significant correlation between emergency patient mortality rate and patient's vital signs obtained at the triage desk(HR>120 beats/min,systolic BP<90 mmHg,diastolic BP<60 mmHg).MSI is a stronger predictor of emergency patient mortality compared to heart rate and blood pressure alone,whereas SI does not have a significant correlation with emergency patient mortality rate.CONCLUSION:MSI is a clinically significant predictor of mortality in emergency patients.It may be better than using heart rate and blood pressure alone.SI is not significantly correlated with the mortality rate of the emergency patient.

Estimating time-based instantaneous total mortality rate based on the age-structured abundance index

The instantaneous total mortality rate(Z) of a fish population is one of the important parameters in fisheries stock assessment. The estimation of Z is crucial to fish population dynamics analysis,abundance and catch forecast,and fisheries management. A catch curve-based method for estimating time-based Z and its change trend from catch per unit effort(CPUE) data of multiple cohorts is developed. Unlike the traditional catch-curve method,the method developed here does not need the assumption of constant Z throughout the time,but the Z values in n continuous years are assumed constant,and then the Z values in different n continuous years are estimated using the age-based CPUE data within these years. The results of the simulation analyses show that the trends of the estimated time-based Z are consistent with the trends of the true Z,and the estimated rates of change from this approach are close to the true change rates(the relative differences between the change rates of the estimated Z and the true Z are smaller than 10%). Variations of both Z and recruitment can affect the estimates of Z value and the trend of Z. The most appropriate value of n can be different given the effects of different factors. Therefore,the appropriate value of n for different fisheries should be determined through a simulation analysis as we demonstrated in this study. Further analyses suggested that selectivity and age estimation are also two factors that can affect the estimated Z values if there is error in either of them,but the estimated change rates of Z are still close to the true change rates. We also applied this approach to the Atlantic cod(G adus morhua) fishery of eastern Newfoundland and Labrador from 1983 to 1997,and obtained reasonable estimates of time-based Z.

Evaluation and Estimation of the Provincial Infant Mortality Rate in China's Sixth Census

Objective To assess the data quality and estimate the provincial infant mortality rate（1q0） from China＇s sixth census. Methods A log-quadratic model is applied to under-fifteen data. We analyze and compare the average relative errors（AREs） for 1q0 between the estimated and reported values using the leave-one-out cross-validation method. Results For the sixth census, the AREs are more than 100% for almost all provinces. The estimated average 1q0 level for 31 provinces is 12.3‰ for males and 10.7‰ for females. Conclusion The data for the provincial 1q0 from China＇s sixth census have a serious data quality problem. The actual levels of 1q0 for each province are significantly higher than the reported values.

Age,growth,and mortality rate of the yellow goosefish Lophius litulon(Jordan,1902)in the Yellow Sea

With the decline in the most fisheries resources in the Yellow Sea,the yellow goosefish Lophius litulon has increased in commercial and ecological importance in recent years.We studied the length distribution,length-weight relationship,age composition,growth pattern,mortality,and exploitation rates of the yellow goosefish in the Yellow Sea.Total length(TL)of females and males ranged from 173 to 582 mm and 178 to 500 mm,respectively.The length-weight relationships were also estimated for females and males.Age classes from 2 to 4 years predominated in the samples.The von Bertalanffy growth function(VBGF),estimated based on non-linear least-squares methodology,showed significant differences between sexes.Females attained a greater estimated asymptotic total length(765 mm TL)compared to males(579 mm TL).The VBGF did not differ significantly between stocks of the northern Yellow Sea and the southern Yellow Sea.Estimated natural instantaneous mortality rate(M)ranged from 0.25/a to 0.33/a based on four age-and length-based methods.Total instantaneous mortality rate(Z)of total samples calculated by the age-based catch curve method was 0.591/a and the average fishing mortality(F)was 0.30/a.Estimated exploitation rate(E)was approximately 0.5,indicating that the population of L.litulon in the Yellow Sea may be sustainable.These results provide a reference for the present status of L.litulon and information for the management.

SutteARIMA:A Novel Method for Forecasting the Infant Mortality Rate in Indonesia

This study focuses on the novel forecasting method(SutteARIMA)and its application in predicting Infant Mortality Rate data in Indonesia.It undertakes a comparison of the most popular andwidely used four forecasting methods:ARIMA,Neural Networks Time Series(NNAR),Holt-Winters,and SutteARIMA.The data used were obtained from the website of the World Bank.The data consisted of the annual infant mortality rate(per 1000 live births)from 1991 to 2019.To determine a suitable and best method for predicting InfantMortality rate,the forecasting results of these four methods were compared based on the mean absolute percentage error(MAPE)and mean squared error(MSE).The results of the study showed that the accuracy level of SutteARIMA method(MAPE:0.83%andMSE:0.046)in predicting InfantMortality rate in Indonesia was smaller than the other three forecasting methods,specifically the ARIMA(0.2.2)with a MAPE of 1.21%and a MSE of 0.146;the NNAR with a MAPE of 7.95%and a MSE of 3.90;and the Holt-Winters with aMAPE of 1.03%and aMSE:of 0.083.

CHARACTERISTICS OF MORTALITY RATES FROM BREAST AND OVARIAN CANCER IN JAPAN

Objective: Breast and ovarian cancer is rare in Japan compared with other developed countries but their mortality rates are increasing. It is necessary to examine the experience of Japan as a guide to further prevent breast and ovarian cancer in our country. Methods: We conducted an epidemiological study of breast and ovarian cancer in the past 50 years to investigate the trends and characteristics of the mortality rates in Japan. The numbers of age-specific death from breast and ovarian cancer and the population of 5-year groups were obtained from the Vital Statistics of Japan. The truncated age specific mortality rates were calculated according to the patterns of age specific mortality rates from both cancers. Age adjustments were made to the standard world population. Results: In the past 50 years, mortality rates of breast and ovarian cancer increased about 2 or 6 fold, respectively. This increase was most marked over 50 years old. The death pattern of breast cancer was same as that of ovarian cancer, but that of ovarian cancer changed greatly with time. The birth cohort study had some interesting findings. Common to breast and ovarian cancer, the later the year of birth, the higher the mortality rates from both malignancies in later life. Conclusion: The increase of the yearly mortality rates from breast and ovarian cancer might be due to changes in lifestyle and environmental factors. We are very concerned about dietary practices. Further investigation is needed to clarify the possible causes of animal food.

Objective: To explore the trends of incidence and mortality rates of stroke in Hanzhong rural population. Methods: Acting as the WHO MONICA project. Results: The incidence rate of stroke was 152.9/100 000. There was decline trend in male(P<0.05). The mortality rate of stroke was 115.9/100 000. There was no significant decline trend during 18-year period (P<0.05). The incidence and mortality rates of stroke of male were higher than those of female(P<0.05).The incidence and mortality rates were all increased with age(P<0.01). Conclusion: It must stick to the long- term prevention measures to decrease incidence rate, and improve the condition of medical treatment to reduce the mortality rate in rural population.

Flock Dynamics and Approaches for Reducing Mortality Rate among Mubende Goats at BuZARDI Semi-Intensive Farm, Hoima, Uganda

Goats are globally very important domestic small ruminants being kept for meat, milk, skin, byproducts and several socio-cultural purposes. Goat farmers in the Lake Albert Crescent Zone (LACZ) of Uganda identified dry-season feed scarcity, poor breeds, diseases, informal marketing and theft as major constraints which underscore the scarcity of information on improved management technologies and the need for targeted decisions. At BuZARDI goat farm, a semi-intensive farm that is also experiencing similar challenges, we documented management practices and collected production related data for 2 years. We computed flock dynamics and mortality rates purposely to influence decisions aimed at increasing the farm’s productivity. Data were collected using pens and books, validated and analyzed using MS office 2013 and SPSS version 22. The flock size increased from 37 goats in July 2020 to 175 goats in June 2022. One hundred twenty-five goats were introduced into the farm as breeding stock, 89 kids were born on the farm and 61 goats died due to various causes. The average number of goats in the farm per month was 109.2 (SEM = 13.7), female 79.8 (SEM = 10.8) and male 29.4, (SEM = 9.9). Average population of goats at risk of death was 95 and the Mortality rate was 27 goats per 1000 goat months. The disaggregated mortality rate of 5 goats per 1000 goat months and 39 goats per 1000 goat months were obtained for the period FY 2020-2021 and FY2021-2022 respectively. The main contributors to the mortality of goats were worm infestation (33%), fracture and injuries arising from stampedes (18%), Ticks and tick borne diseases (18%), respiratory tract infections (11%) and malnutrition (10%). We recommend strict adherence to the flock health program;improved parasite management, separation & improved care for kids, vaccinations, safer feeding, and evidence based disease management, adoption of digital data collection tools and development of an appropriate app for more accurate determination of mortality rates.

Linear Mixed Model Analysis of Worldwide Longitudinal Infant Mortality Rate Data and Association with Human Development Index

A linear mixed model is used to determine the explaining infant mortality rate data of United Nations countries. The HDI （human development index） has a significant negative linear relationship with infant mortality rate. United Nations data shows that the infant mortality rate has a descending trend over the period 1990-2010. This study aims to assess the value of the HDI as a predictor of infant mortality rate. Findings in the paper suggest that significant percentage reductions in infant mortality might be possible for countries for controlling the HDI.

Trends of autoimmune liver disease inpatient hospitalization and mortality from 2011 to 2017:A United States nationwide analysis

BACKGROUND Autoimmune liver diseases(AiLD)encompass a variety of disorders that target either the liver cells(autoimmune hepatitis,AIH)or the bile ducts[primary biliary cholangitis(PBC),and primary sclerosing cholangitis(PSC)].These conditions can progress to chronic liver disease(CLD),which is characterized by fibrosis,cirrhosis,and hepatocellular carcinoma.Recent studies have indicated a rise in hospitalizations and associated costs for CLD in the US,but information regarding inpatient admissions specifically for AiLD remains limited.AIM To examine the trends and mortality of inpatient hospitalization of AiLD from 2011 to 2017.METHODS This study is a retrospective analysis utilizing the National Inpatient Sample(NIS)databases.All subjects admitted between 2011 and 2017 with a diagnosis of AiLD(AIH,PBC,PSC)were identified using the International Classification of Diseases(ICD-9)and ICD-10 codes.primary AiLD admission was defined if the first admission code was one of the AiLD codes.secondary AiLD admission was defined as having the AiLD diagnosis anywhere in the admission diagnosis(25 diagnoses).Subjects aged 21 years and older were included.The national estimates of hospitalization were derived using sample weights provided by NIS.χ^(2)tests for categorical data were used.The primary trend characteristics were in-hospital mortality,hospital charges,and length of stay.RESULTS From 2011 to 2017,hospitalization rates witnessed a significant decline,dropping from 83263 admissions to 74850 admissions(P<0.05).The patients hospitalized were predominantly elderly(median 53%for age>65),mostly female(median 59%)(P<0.05),and primarily Caucasians(median 68%)(P<0.05).Medicare was the major insurance(median 56%),followed by private payer(median 27%)(P<0.05).The South was the top geographical distribution for these admissions(median 33%)(P<0.05),with most admissions taking place in big teaching institutions(median 63%)(P<0.05).Total charges for admissions rose from 66031 in 2011 to 78987 in 2017(P<0.05),while the inpatient mortality rate had a median of 4.9%(P<0.05),rising from 4.67%in 2011 to 5.43%in 2017.The median length of stay remained relatively stable,changing from 6.94 days(SD=0.07)in 2011 to 6.51 days(SD=0.06)in 2017(P<0.05).Acute renal failure emerged as the most common risk factor associated with an increased death rate,affecting nearly 68%of patients(P<0.05).CONCLUSION AiLD-inpatient hospitalization showed a decrease in overall trends over the studied years,however there is a significant increase in financial burden on healthcare with increasing in-hospital costs along with increase in mortality of hospitalized patient with AiLD.

Effects of Tetramethylpyrazine on Cardiac Function and Mortality Rate in Septic Rats

Objective： To study the effects of tetramethylpyrazine （TMP） on cardiac function and mortality rate in septic rats. Methods： Fifty male Sprague-Dawley rats were randomized into a sham-operation group （sham group, n=10）, normal saline group （NS group, n=20）, and TMP group （n=20）. The rats in the NS and TMP groups underwent cecal ligation and puncture （CLP） to induce sepsis. Rats in the NS group were injected with NS （10 mL/kg） immediately after CLP and 6 h after CLP. Rats in the TMP group were injected with TMP （10 mg/kg） at the same time points. Twenty-four hours after modeling, the mortality rates were observed in each group. Cardiac function and serum concentration of tumor necrosis factor α （TNF-α） were also tested. The correlation between TNF-α and the ejection fraction （EF） was observed. Left ventricle specimens were reserved for histomorphologic study. Results： Compared with the sham group, the NS and TMP groups had decreased EF values and increased mortality rates and serum TNF-α levels （P〈0.05）. The TMP group had a comparatively lower mortality rate and TNF-α level and a higher EF value compared with the NS group （P〈0.05）. Histomorphology indicated that myocardial inflammation in the TMP group was mild compared with that in the NS group. There was a negative correlation between TNF-α level and EF value （r=-0.583, P=0.000）. Conclusion： TMP could reduce the mortality rate of septic rats and had certain protective effects on cardiac function.

Mortality rates of pathogen indicator microorganisms discharged from point and non-point sources in an urban area

This research measured the mortality rates of pathogen indicator microorganisms discharged from various point and non-point sources in an urban area. Water samples were collected from a domestic sewer, a combined sewer overflow, the effluent of a wastewater treatment plant, and an urban river. Mortality rates of indicator microorganisms in sediment of an urban fiver were also measured. Mortality rates of indicator microorganisms in domestic sewage, estimated by assuming first order kinetics at 20℃ were 0.197 day^-1, 0.234 day^-1, 0.258 day^-1 and 0.276 day^-1 for total coliform, fecal coliform, Escherichia coli, and fecal streptococci, respectively. Effects of temperature, sunlight irradiation and settlement on the mortality rate were measured. Results of this research can be used as input data for water quality modeling or can be used as design factors for treatment facilities.

National Breast Cancer Mortality and Incidence Rates According to the Human Development Index: An Ecological Study

Background: This study aimed to identify the role of human development index (HDI) in the incidence and mortality rates of breast cancer (BC) worldwide. Methods: Data on the age-standardized incidence and mortality rates of BC for 184 countries were obtained from the GLOBOCAN. Data about the HDI and other indices were obtained from the World Bank Report 2013. Linear regression model was used for assessment the effect of HDI on BC occurrence rates. Results: In 2012, BCs were estimated to have affected a total of 1,671,149 individuals (crude rate: 47.8 per 100,000 individuals), and caused 521,907 deaths worldwide (crude rate: 14.7 per 100,000 individuals). Nearly half of total female BC cases (46.3%) with the highest risk of incidence (age-standardized Rate (ASR): 128 per 100,000) had occurred in very high HDI regions. The most proportion of the mortality burden was in low HDI and medium HDI areas. Linear regression analyses showed a direct significant correlation between the incidence of BC and HDI at the global level (B = 104.5, P < 0.001). The mortality rate of BC was not significantly associated with HDI (B = 3.26, P = 0.160). Conclusion: Our study showed that the burden of female BC is enormous in very high HDI and low HID regions. Targeted interventions have the ability to reduce this number significantly through resource-dependent interventions. Moreover, further reductions in mortality could be brought about by increasing access to curative treatment for patients with BC.

Influencing Factors and Mortality Prediction of Covid-19 Contact Infection Rate in China

Taking the COVID-19 data from 2020-1-23 to 3-21 days released by the China Health Protection Committee as the sample,the hospital remaining rate,mortality rate and cure rate are selected as covariates,and the contact infection rate is used as response variable to establish a high precision ADL model,results of return substitution show that the predicted value of contact infection rate almost coincides with the sample value,and shows three stages of change characteristics.After March 1,2020,the overall trend is downward,stable below 12%.Main influencing factors of contact infection rate are analyzed quantitatively.Based on this,the ARIMA(1,2,2)model is established to analyze and predict the mortality change trend.The results showed that the domestic COVID-19 mortality rate is stable near 4%after 2020-3-27.

Mortality in Cardiology in Sub-Saharan Africa: Case of the Cardiology Department of the Teaching Hospital Sylvanus Olympio of Lome

Background: Cardiovascular disease is the leading cause of death worldwide. The specificities of cardiology mortality in Togo are not well known. The objective of this study was to determine the profile of deaths in the cardiology department of the Sylvanus Olympio Teaching Hospital (CHU SO) in Lome. Materials and Methods: This was a cross-sectional study conducted over a period of 06 years, from January 1, 2015 to December 31, 2021, in the cardiology department of the Sylvanus Olympio Teaching Hospital in Lome. In this study, we included all medical records of patients who died in hospital in the cardiology department during the study period. Results: During the study period, 2762 patients were hospitalized in the cardiology unit at CHU SO. We recorded 112 deaths meeting our criteria, for an intrahospital mortality rate of 4.19%. The average age of patients was 53.79 ± 18.27 years. Hypertension was present in 47.3%. Sickness insurance coverage was not available for 94.64% of those who died. The major cardiovascular diseases observed were myocardium in 43.75% whose dilated cardiomyopathy accounted for 71.42%;and rhythmic lesions in 34.82%. Biological infectious syndrome (56.25%), renal failure (48.21%), anemia (47.27%), lung infection (32.14%), hyponatremia (33.04%) were the main comorbidities observed. Among the circumstances of death, sudden death was found in 32.14%, cardiogenic shock in 20.54% and septic shock in 13.39%. Conclusion: The profile of deaths in the cardiology department of the CHU SO reveals that myocardial injuries are more present with circumstances of death dominated by sudden death.

Improving colorectal cancer screening programs

In this editorial we comment on the article by Agatsuma et al published in the World Journal of Gastroenterology.They suggest policies for more effective colorectal screening.Screening is the main policy that has led to lower mortality rates in later years among the population that was eligible for screening.Colonoscopy is the gold standard tool for screening and has preventive effects by removing precancerous or early malignant polyps.However,colonoscopy is an invasive process,and fecal tests such as the current hemoglobin immunodetection were developed,followed by endoscopy,as the general tool for population screening,avoiding logistical and economic problems.Even so,participation and adherence rates are low.Different screening options are being developed with the idea that if people could choose between the ones that best suit them,participation in population-based screening programs would increase.Blood tests,such as a recent one that detects cell-free DNA shed by tumors called circulating tumor DNA,showed a similar accuracy rate to stool tests for cancer,but were less sensitive for advanced precancerous lesions.At the time when the crosstalk between the immune system and cancer was being established as a new hallmark of cancer,novel immune system-related biomarkers and information on patients’immune parameters,such as cell counts of different immune populations,were studied for the early detection of colorectal cancer,since they could be effective in asymptomatic people,appearing earlier in the adenoma-carcinoma development compared to the presence of fecal blood.sCD26,for example,detected 80.37%of advanced adenomas.To reach as many eligible people as possible,starting at an earlier age than current programs,the direction could be to apply tests based on blood,urine or salivary fluid to samples taken during routine visits to the primary health system.

Determinants of Home Deliveries by Pregnant Mothers in Lumbo Chabbobboma Zone of Gwembe District in Zambia

Background: Home deliveries is still high globally at 42% WHO 2022, due to high home deliveries, maternal death is also high at 43% globally. In sub-Sahara region home deliveries still high. Giving birth at health facilities in most of sub-Saharan African countries Zambia inclusive is still a challenge whereby more than 51% of first-time mothers give birth at home and this gives a risk of high maternal and perinatal deaths. Therefore Reducing number of home deliveries is important to improve maternal and perinatal health issues. In this study, the aim was to investigate the determinants of home deliveries by pregnant mothers in the Luumbo zone of Gwembe district, Zambia. Purpose: Access to skilled care and facilities with capacity to provide emergency and newborn care is critical to reduce maternal death. In Zambia 42% of women still deliveries from home, suggesting a persistent challenge for women to seek, reach, and receive quality maternity care. This study aimed investigate the determinants of home deliveries by pregnant mothers in Luumbo zone of Gwembe district, Zambia. Methods: The study was conducted among postnatal mothers who came for postnatal care at 6 weeks in Luumbo Chabbobboma clinic in Gwembe district southern province of Zambia. This was a descriptive cross-sectional study where a Simple random sampling technique was used to select 105 women of childbearing age who attended postnatal and had a recent delivery. Data were collected using a researcher-administered structured questionnaire to identify determinants of home deliveries in Luumbo Chabbobboma zone. Data analysis was done using SPSS computer software version 27.0. Both descriptive and inferential (chi-square test) analyses were performed and statistical significance was taken at α ≤ 0.05. Results: The results show that 46 (43.8%) respondents were in the age bracket 20 - 29 years. Of the 105 respondents included in the study, 24 (22.9%) of them delivered from home. The results show that high maternal age (p = 0.03), occupation (p = 0.024), distance to the facility (p = 0.014), means of transportation (p = 0.023), multiparity (p = 0.01), timing and number of ANC visits (p Conclusion: From this population. The major reason why women still deliver at home was long distance to the nearest facility. To reduce maternal and perinatal mortality access to health facilities by pregnant women needs to be improved. There should also be active engagement of the traditional and religious institutions in the area.

Machine Learning Prediction of Fetal Health Status from Cardiotocography Examination in Developing Healthcare Contexts

Reducing neonatal mortality is a critical global health objective,especially in resource-constrained developing countries.This study employs machine learning(ML)techniques to predict fetal health status based on cardiotocography(CTG)examination findings,utilizing a dataset from the Kaggle repository due to the limited comprehensive healthcare data available in developing nations.Features such as baseline fetal heart rate,uterine contractions,and waveform characteristics were extracted using the RFE wrapper feature engineering technique and scaled with a standard scaler.Six ML models—Logistic Regression(LR),Decision Tree(DT),Random Forest(RF),Gradient Boosting(GB),Categorical Boosting(CB),and Extended Gradient Boosting(XGB)—are trained via cross-validation and evaluated using performance metrics.The developed models were trained via cross-validation and evaluated using ML performance metrics.Eight out of the 21 features selected by GB returned their maximum Matthews Correlation Coefficient(MCC)score of 0.6255,while CB,with 20 of the 21 features,returned the maximum and highest MCC score of 0.6321.The study demonstrated the ability of ML models to predict fetal health conditions from CTG exam results,facilitating early identification of high-risk pregnancies and enabling prompt treatment to prevent severe neonatal outcomes.

The Prognostic Value of Red Cell Distribution Width in Critically Ill Cerebral Infarction Patients:A Retrospective Cohort Study

Objective:Red blood cell distribution width(RDW)has been utilized as a prognostic indicator for mortality risk assessment in cardiovascular and cerebrovascular patients.Nevertheless,the prognostic significance of RDW in critically ill patients with cerebral infarction is yet to be investigated.The objective of this study is to examine the association between RDW and the risk of all-cause mortality in cerebral infarction patients admitted to the intensive care unit(ICU).Method:A retrospective cohort study was conducted using the Medical Information Mart for Intensive Care IV 2.2(MIMIC-IV)intensive care dataset for data analysis.The main results were the all-cause mortality rates at 3 and 12 months of follow-up.Cumulative curves were plotted using the Kaplan-Meier method,and Cox proportional hazards analysis was used to examine the relationship between RDW and mortality rates in critically ill cerebral infarction patients.Results:The findings indicate that RDW serves as a significant prognostic factor for mortality risk in critically ill stroke patients,specifically at the 3 and 12-month follow-up periods.The observed correlation between increasing RDW levels and higher mortality rates among cerebral infarction patients further supports the potential utility of RDW as a predictive indicator.Conclusion:RDW emerges as an independent predictor of mortality risk during the 3 and 12-month follow-up periods for critically ill patients with cerebral infarction.
