We believe that comprehensive rehabilitation can improve a patient’s overall functioning during their short term stay in SNFs. The purpose of this study is to determine if an individual’s level of independence improved after admission to a skilled nursing facility and procurement of rehabilitation services. Methods: This study retrospectively reviewed 4612 nursing home patients in California who underwent rehabilitative services at skilled nursing facilities to determine how the patients responded to their environments, therapy interventions, and any other additional supportive measures. The records of patients who were admitted for short-term rehabilitation were reviewed in a blinded fashion, looking specifically at Section GG of the Minimum Data Set (MDS). Self-Care Section GG scores recorded by rehabilitative staff provide objective data and measure patients’ levels of assistance that were required. Each activity is scored from 1, being completely dependent, to 6, being entirely independent, with varying levels of assistance with scores in between. The admission scores versus the discharge scores can be compared to determine if a patient improved their level of functioning upon discharge. Results: Utilizing the Pearson’s correlation coefficient, a strong correlation of improvement in ADL performance on Section GG between the admission and discharge scores was identified, implying significant improvement in functional independence upon discharge. The average percent improvement for Managed Care patients was ~35.4% and ~39.4% for Medicare patients. Conclusions: The results support the benefits of rehabilitation services in skilled nursing facilities, and the data suggests that admission scores can be used as a predictive tool for functional outcomes.展开更多

Material and Methods: This study included 150 male participants. They were divided according to the levels into three equal groups: levels 5, 6, and 7 (group I), levels 8, 9, 10 (group II) and levels 11, 12, and interns (group III). This study consisted of questions related to age, gender, educational level, father’s education, mother’s education, home ownership, brushing teeth more than or twice a day, in addition to daily lifestyle habits that were daily smoking, daily use of sugary drinks, and daily use of sugary foods. Some clinical parameters of plaque-induced gingivitis and periodontitis and the percentage of radiographic bone loss were recorded. All data were collected and analyzed using Tukey’s test and Chi-square test. A P-value of less than 0.5 (p Results: One hundred fifty male dental students of different levels in the college of dentistry at King Khalid University participated in the study in three groups (I, II, and III). The mean age of group III is more than that of group II and group I, with highly statistically significant differences (p 30%) were more among the participants in group I than the participants in groups III and II. There was an increase in the percentage of affected participants with stages III and IV of clinical attachment loss (CAL), periodontal pocket depth (PPD), radiographic bone loss (%RBL), tooth mobility, as well as glycated hemoglobin (HbA1c) test values (>7%), and the number of cigarettes smoked per day (>10 cigs) in group III more than in group II and I. Conclusion: We conclude that the severity and grading of plaque-induced gingivitis were higher among the participants in group I, while the severity and grading of periodontitis were higher among the participants in group III due to the different impact of their daily lifestyle habits.展开更多

However, fitness tracking assessment methods are ambiguous because they may differ from model to model. Objective: This study aimed to compare the stress level, heart rate, sleep time, number of steps, and distance traveled, which were calculated using fitness tracking methods for daily-life free activity installed in various smartwatches. Materials and Methodology: Healthy women in their 20s to 30s were recruited for this study, which was conducted from December 2021 to June 2022. The finalized participants wore three different smartwatch models (Mi smartband 6, vivosmart<sup>®</sup>4, and Band 6) simultaneously on their person for 48 hours and performed their daily activities and recorded them on an hour-based activity chart. Each smartwatch’s measured data (e.g., age, height, weight, and oral medications) were extracted into five datasets: heart rate, stress level, number of steps, distance, and sleep time. Data analyses were conducted using Spearman’s rank correlation coefficient ρ (for comparing heart rates) and Bland-Altman plots (for assessing heart rate agreement). The smartwatches’ fitness trackers were compared using the mean absolute percentage error. Results: The correlation coefficient showed that vivosmart<sup>®</sup>4 and Band 6 had a higher heart rate agreement (ρ = 0.684). The Bland-Altman plots showed high agreement between Band 6, Mi smartband 6, and vivosmart<sup>®</sup>4. The heart rate measurement method used under free movement was found to be consistent. The examined smartwatches were able to measure heart rate at the same level even under daily-life free movements. Conclusion: Several different smartwatches’ calculated measured values for heart rate had a high agreement. The smartwatches provided accurate heart rate measurements under daily-life free movement conditions. Furthermore, the calculation methods for stress level were found to differ in the fitness tracking of all the smartwatches. .展开更多

The policy of enhanced recovery after surgery has been implemented after cesarean section to optimize perioperative care. Enhanced recovery also aims to reduce the length of hospital stay, which might imply substantial healthcare savings. Rising hospital costs are one of the factors in early discharge. Patients & Methods: This was a prospective cohort study. 158 patients met the inclusion criteria of the study, 81 patients were discharged after 48 hours and 77 patients were discharged after 24 hours. All patients received the same postoperative care and instructions. All the study participants received a phone call 1, 3, and 5 days after discharge to objectively assess the activities of daily living through Katz index of independence in activities of daily living. All patients were offered a postpartum visit 1 week after discharge during which the wound was assessed by the Southampton wound assessment scale. Moreover, other maternal complications such as mastitis, puerperal sepsis, or pyelonephritis were assessed and cases who were readmitted were documented. Initiation of successful breastfeeding and neonatal readmission were reported as well. Results: 158 patients met the inclusion/exclusion criteria of the study. There was no significant difference between the two arms of the study regarding baseline characteristics. Katz index of independence showed that the resumption of activities of daily living after CS was similar in both arms of the study on days 1, 3 and 5 after discharge. Time till the passage of flatus and stool after the cesarean section was significantly shorter among the early discharge arm (9.31 VS 14.68, p value < 0.001 & 13.25 VS 24.82, p value < 0.001 respectively). Maternal readmission was not significantly higher among the early discharge arm and at the 1-week postpartum visit, objective wound assessment by Southampton wound scoring assessment was made and there was no significant difference between the two arms of the study. Initiation of successful breastfeeding, and neonatal readmission were similar in both groups. Conclusion: The policy of early discharge can be adopted in low-risk cases scheduled for elective uncomplicated CS provided that the mother and the neonate are in good general condition and proper instructions regarding red flag manifestations are given.展开更多

The DLP-WNN model obtains the daily forecast result byweighed summation of the daily output values of the two subnets. Subnet 1 reflects the overall trend of dailypassenger volumes in the recent period, and subnet 2 the daily fluctuation of the daily passenger volume toensure the accuracy of medium-term forecast.Findings – According to the example application, in which the DLP-WNN modelwas used for the medium-termforecast of the daily passenger volumes for 120 days for typical O-D pairs at 4 different distances, the averageabsolute percentage error is 7%-12%, obviously lower than the results measured by the Back Propagation (BP)neural network, the ELM (extreme learning machine), the ELMAN neural network, the GRNN (generalizedregression neural network) and the VMD-GA-BP. The DLP-WNN model was verified to be suitable for themedium-term forecast of the daily passenger volume of HSR.Originality/value – This study proposed a Double Layer Parallel structure forecast model for medium-termdaily passenger volume (about 120 days) of HSR systems by using the date and holiday labels and WaveletNeural Network. The predict results are important input data for supporting the line planning, scheduling andother decisions in operation and management in HSR systems.展开更多

文摘Background Rumen bacterial groups can affect growth performance,such as average daily gain(ADG),feed intake,and efficiency.The study aimed to investigate the inter-relationship of rumen bacterial composition,rumen fermentation indicators,serum indicators,and growth performance of Holstein heifer calves with different ADG.Twelve calves were chosen from a trail with 60 calves and divided into higher ADG(HADG,high pre-and post-weaning ADG,n=6)and lower ADG(LADG,low pre-and post-weaning ADG,n=6)groups to investigate differences in bacterial composition and functions and host phenotype.Results During the preweaning period,the relative abundances of propionate producers,including g_norank_f_Butyricicoccaceae,g_Pyramidobacter,and g_norank_f_norank_o_Clostridia_vadin BB60_group,were higher in HADG calves(LDA>2,P<0.05).Enrichment of these bacteria resulted in increased levels of propionate,a gluconeogenic precursor,in preweaning HADG calves(adjusted P<0.05),which consequently raised serum glucose concentrations(adjusted P<0.05).In contrast,the relative abundances of rumen bacteria in post-weaning HADG calves did not exert this effect.Moreover,no significant differences were observed in rumen fermentation parameters and serum indices between the two groups.Conclusions The findings of this study revealed that the preweaning period is the window of opportunity for rumen bacteria to regulate the ADG of calves.
文摘Background: Self-care tasks or activities of daily living (ADL)’s performance are often disrupted after an older adult sustains an injury or illness, which can be a determining factor for discharge placement after hospitalization, or it can determine the level of assistance required after discharge from a skilled nursing facility (SNF). We believe that comprehensive rehabilitation can improve a patient’s overall functioning during their short term stay in SNFs. The purpose of this study is to determine if an individual’s level of independence improved after admission to a skilled nursing facility and procurement of rehabilitation services. Methods: This study retrospectively reviewed 4612 nursing home patients in California who underwent rehabilitative services at skilled nursing facilities to determine how the patients responded to their environments, therapy interventions, and any other additional supportive measures. The records of patients who were admitted for short-term rehabilitation were reviewed in a blinded fashion, looking specifically at Section GG of the Minimum Data Set (MDS). Self-Care Section GG scores recorded by rehabilitative staff provide objective data and measure patients’ levels of assistance that were required. Each activity is scored from 1, being completely dependent, to 6, being entirely independent, with varying levels of assistance with scores in between. The admission scores versus the discharge scores can be compared to determine if a patient improved their level of functioning upon discharge. Results: Utilizing the Pearson’s correlation coefficient, a strong correlation of improvement in ADL performance on Section GG between the admission and discharge scores was identified, implying significant improvement in functional independence upon discharge. The average percent improvement for Managed Care patients was ~35.4% and ~39.4% for Medicare patients. Conclusions: The results support the benefits of rehabilitation services in skilled nursing facilities, and the data suggests that admission scores can be used as a predictive tool for functional outcomes.

文摘After approaching 0℃owing to an Atlantic storm at the end of 2015,the Arctic temperature approached freezing again in 2022,indicating that Arctic daily warming events remain a concern.The NCEP/NCAR Reanalysis dataset was used to investigate the influence of the NAO on the Arctic winter daily warming events induced by Atlantic storms,known as the Atlantic pattern-Arctic Rapid Tropospheric Daily Warming(Atlantic-RTDW)event.Atlantic-RTDW events are triggered by Atlantic storms that transport warm and humid air masses moving into the Arctic.Furthermore,an interdecadal change in the influence of NAO on Atlantic-RTDW-event frequency was observed around the mid-1980s.Specifically,before the mid-1980s(pre-transition period),500-hPa southerly(northerly)wind anomalies occupied the North Atlantic(NA)in the positive(negative)phase of NAO,which increased(decreased)the Atlantic-RTDW events occurrence by steering Atlantic storms into(away from)the Arctic;thus,the NAO could potentially influence the Atlantic-RTDW-event frequency.However,the relationship between the NAO and the Atlantic-RTDW-event frequency has weakened since the mid-1980s(post-transition period).In the post-transition period,such 500-hPa southerly(northerly)wind anomalies over the NA hardly existed in the positive(negative)phase of NAO,which was attributed to a stronger Atlantic Storm Track(AST)activity intensity than that in the pre-transition period.During this period,the strong AST induced an enhanced NAOrelated cyclone via transient eddy-mean flow interactions,resulting in the disappearance of southerly and northerly wind anomalies over the NA.
文摘Objective: To assess daily lifestyle habits as risk factors for plaque-induced gingivitis and periodontitis severity and grading among samples of dental students at King Khalid University. Material and Methods: This study included 150 male participants. They were divided according to the levels into three equal groups: levels 5, 6, and 7 (group I), levels 8, 9, 10 (group II) and levels 11, 12, and interns (group III). This study consisted of questions related to age, gender, educational level, father’s education, mother’s education, home ownership, brushing teeth more than or twice a day, in addition to daily lifestyle habits that were daily smoking, daily use of sugary drinks, and daily use of sugary foods. Some clinical parameters of plaque-induced gingivitis and periodontitis and the percentage of radiographic bone loss were recorded. All data were collected and analyzed using Tukey’s test and Chi-square test.

文摘Peasant painting is a kind of painting created by farmers as creative subject,bearing rich significance.According to the historical development of peasant painting in reality,the types of meaning it carried could be divided into three types in chronological order:political ideological significance,folk life significance,and creative fashion significance.These three types of meaning gave rise to three types of aesthetic utopia,namely political aesthetic utopia,folk aesthetic utopia and fashion aesthetic utopia.The three types of aesthetic utopia reflected three forms of negation and revolution of daily life.What the political aesthetic utopia resisted was the alienation force of material desire.What folk aesthetic utopia resisted was the desire for material and the binding of political ideology.The fashion aesthetic utopia opposed the relatively narrow localism.Through these three forms of resistance,the public also constructed three identities:the interpreter of their own aesthetic interpretation of political ideology,the interpreter of their own aesthetic interpretation of real life from perspective of local feelings,and the interpreter of their own aesthetic interpretation of real life from perspective of the relationship between themselves and the world.
文摘Background: Young women of reproductive age experience various physiological changes, which they measure and track using various devices, including fitness trackers and smartwatches. However, fitness tracking assessment methods are ambiguous because they may differ from model to model. Objective: This study aimed to compare the stress level, heart rate, sleep time, number of steps, and distance traveled, which were calculated using fitness tracking methods for daily-life free activity installed in various smartwatches. Materials and Methodology: Healthy women in their 20s to 30s were recruited for this study, which was conducted from December 2021 to June 2022. The finalized participants wore three different smartwatch models (Mi smartband 6, vivosmart<sup>®</sup>4, and Band 6) simultaneously on their person for 48 hours and performed their daily activities and recorded them on an hour-based activity chart. Each smartwatch’s measured data (e.g., age, height, weight, and oral medications) were extracted into five datasets: heart rate, stress level, number of steps, distance, and sleep time. Data analyses were conducted using Spearman’s rank correlation coefficient ρ (for comparing heart rates) and Bland-Altman plots (for assessing heart rate agreement). The smartwatches’ fitness trackers were compared using the mean absolute percentage error. Results: The correlation coefficient showed that vivosmart<sup>®</sup>4 and Band 6 had a higher heart rate agreement (ρ = 0.684). The Bland-Altman plots showed high agreement between Band 6, Mi smartband 6, and vivosmart<sup>®</sup>4. The heart rate measurement method used under free movement was found to be consistent. The examined smartwatches were able to measure heart rate at the same level even under daily-life free movements. Conclusion: Several different smartwatches’ calculated measured values for heart rate had a high agreement. The smartwatches provided accurate heart rate measurements under daily-life free movement conditions. Furthermore, the calculation methods for stress level were found to differ in the fitness tracking of all the smartwatches. .

文摘In the harvest September,we gather in the romantic Chibi to jointly sow the“seeds”of daily chemical industry for original innovation and technological upgrade.From September 14 to 15,2023,the“2023(14th)China Daily Chemical Industry Forum”,hosted by China Research Institute of Daily Chemical Industry,was grandly opened at Ramada Hotel in Chibi City,Hubei Province.This event,under the guidance of the People’s Government of Chibi City,was undertaken by the China Daily Chemical Industry Information Center and the National Productivity Promotion Center for Surfactant and Detergent Industry,and jointly undertaken by Chibi Business Invitation and Investment Promotion Center and Chibi High-quality Dvelopment Research Institute.
文摘Background: Cesarean section is one of the most common surgeries performed worldwide and its consequences and complications represent a major public health concern. The policy of enhanced recovery after surgery has been implemented after cesarean section to optimize perioperative care. Enhanced recovery also aims to reduce the length of hospital stay, which might imply substantial healthcare savings. Rising hospital costs are one of the factors in early discharge. Patients & Methods: This was a prospective cohort study. 158 patients met the inclusion criteria of the study, 81 patients were discharged after 48 hours and 77 patients were discharged after 24 hours. All patients received the same postoperative care and instructions. All the study participants received a phone call 1, 3, and 5 days after discharge to objectively assess the activities of daily living through Katz index of independence in activities of daily living. All patients were offered a postpartum visit 1 week after discharge during which the wound was assessed by the Southampton wound assessment scale. Moreover, other maternal complications such as mastitis, puerperal sepsis, or pyelonephritis were assessed and cases who were readmitted were documented. Initiation of successful breastfeeding and neonatal readmission were reported as well. Results: 158 patients met the inclusion/exclusion criteria of the study. There was no significant difference between the two arms of the study regarding baseline characteristics. Katz index of independence showed that the resumption of activities of daily living after CS was similar in both arms of the study on days 1, 3 and 5 after discharge. Time till the passage of flatus and stool after the cesarean section was significantly shorter among the early discharge arm (9.31 VS 14.68, p value < 0.001 & 13.25 VS 24.82, p value < 0.001 respectively). Maternal readmission was not significantly higher among the early discharge arm and at the 1-week postpartum visit, objective wound assessment by Southampton wound scoring assessment was made and there was no significant difference between the two arms of the study. Initiation of successful breastfeeding, and neonatal readmission were similar in both groups. Conclusion: The policy of early discharge can be adopted in low-risk cases scheduled for elective uncomplicated CS provided that the mother and the neonate are in good general condition and proper instructions regarding red flag manifestations are given.
文摘The objective of this study was to experimentally evaluate children’s daily food memory and eating habits.The study found that the gender and school location had an impact on the nutritional condition of primary school students as well as the school food scheme.The investigations were based on three hypotheses and three research questions.In this study,the Eating Habits and Daily Dietary Recall Scale was the tool utilized to gather data(EPDDRS).Four experts—three from the department of vocational education and one lecturer in test and measurement evaluation—validated the instrument’s face.The dependability indices of EPDDRS were calculated using Cronbach’s Alpha.While delivering the instruments,the researcher used the direct administration and retrieval approach.58 instructors and a sample size of 1240 students were selected using a systematic random selection approach.The obtained data was examined using mean and standard deviation to address the research objectives,and the null hypotheses were tested using t-test statistics and Analysis of variance(ANOVA)at the 0.05 level of significance.The main conclusions of this study were that the school meal program had a favorable impact on the students’nutritional status.Also,a balanced ration of nutrient-dense meals that were suitably varied was supplied for the students via the school food program.Also,the findings revealed a substantial difference in the mean assessments of male and female students about their eating patterns.On the school meal program’s dietary recall list,students from high,middle,and low socioeconomic status differ significantly.Recommendations were given to the government,schools,and parents based on the study’s findings.The study’s shortcomings were discussed,and recommendations for more research were made.

文摘Purpose – This paper aims to propose a medium-term forecast model for the daily passenger volume of HighSpeed Railway (HSR) systems to predict the daily the Origin-Destination (OD) daily volume formultiple consecutivedays (e.g. 120 days).Design/methodology/approach – By analyzing the characteristics of the historical data on daily passengervolume of HSR systems, the date and holiday labels were designed with determined value ranges.In accordance to the autoregressive characteristics of the daily passenger volume of HSR, the Double LayerParallel Wavelet Neural Network (DLP-WNN) model suitable for the medium-term (about 120 d) forecast of thedaily passenger volume of HSR was established. The DLP-WNN model obtains the daily forecast result byweighed summation of the daily output values of the two subnets. Subnet 1 reflects the overall trend of dailypassenger volumes in the recent period, and subnet 2 the daily fluctuation of the daily passenger volume toensure the accuracy of medium-term forecast.Findings – According to the example application, in which the DLP-WNN modelwas used for the medium-termforecast of the daily passenger volumes for 120 days for typical O-D pairs at 4 different distances, the averageabsolute percentage error is 7%-12%, obviously lower than the results measured by the Back Propagation (BP)neural network, the ELM (extreme learning machine), the ELMAN neural network, the GRNN (generalizedregression neural network) and the VMD-GA-BP. The DLP-WNN model was verified to be suitable for themedium-term forecast of the daily passenger volume of HSR.Originality/value – This study proposed a Double Layer Parallel structure forecast model for medium-termdaily passenger volume (about 120 days) of HSR systems by using the date and holiday labels and WaveletNeural Network. The predict results are important input data for supporting the line planning, scheduling andother decisions in operation and management in HSR systems.
