RESUMO
Pressure injury is a serious and preventable problem in intensive care units. Translating guidelines into clinical practice can reduce the incidence of pressure injury. Identifying clinical status, barriers and facilitators contribute to guideline implementation. To identify the knowledge, attitudes, and practices of pressure injury prevention in Chinese critical care nurses. Secondary data were extracted from a multicentric clinical trial. Knowledge and attitudes toward pressure injury prevention were assessed by a fourteen-item questionnaire. The observed practices were recorded using a case report form. The report complies with the STROBE statement. A total of 950 critical care nurses in 15 hospitals from six provinces of China were investigated. A total of 53.1% of nurses received a median score of 6 points or less. Knowledge regarding the repositioning procedure, risk assessment, and heel pressure injury prevention was insufficient. Over 99% of nurses strongly or somewhat agreed that pressure injury prevention was very important and that they were willing to take measures to prevent pressure injury. A total of 27 781 patient days of pressure injury prevention practice were recorded. Repositioning was the most commonly used prevention measure, followed by support surfaces and prophylactic dressings. A combination of repositioning, support surface, and prophylactic dressing was lacking. Chinese critical nurses showed a low level of knowledge and a positive attitude toward pressure injury prevention. Practices of pressure injury prevention were unsatisfactory. There is a clear gap between the guidelines and clinical practices. The barrier (low-level knowledge) and facilitator (positive attitude) were identified in this study. According to these findings, strategies need to be developed to promote guideline implementation.

Although strict lockdown measurements implemented during the COVID-19 pandemic have dramatically reduced the anthropogenic-based emissions, changes in air quality and its health impacts remain unclear in China. We comprehensively described air pollution during and after the lockdown periods in 2020 compared with 2018-2019, and estimated the mortality burden indicated by the number of deaths and years of life lost (YLL) related to the air pollution changes. The mean air quality index (AQI), PM10, PM2.5, NO2, SO2 and CO concentrations during the lockdown across China declined by 18.2 (21.2%), 27.0 µg/m3 (28.9%), 10.5 µg/m3 (18.3%), 8.4 µg/m3 (44.2%), 13.1 µg/m3 (38.8%), and 0.3 mg/m3 (27.3%) respectively, when compared to the same periods during 2018-2019. We observed an increase in O3 concentration during the lockdown by 5.5 µg/m3 (10.4%), and a slight decrease after the lockdown by 3.4 µg/m3 (4.4%). As a result, there were 51.3 (95%CI: 32.2, 70.1) thousand fewer premature deaths (16.2 thousand during and 35.1 thousand after the lockdown), and 1066.8 (95%CI: 668.7, 1456.8) thousand fewer YLLs (343.3 thousand during and 723.5 thousand after the lockdown) than these in 2018-2019. Our findings suggest that the COVID-19 lockdown has caused substantial decreases in air pollutants except for O3, and that substantial human health benefits can be achieved when strict control measures for air pollution are taken to reduce emissions from vehicles and industries. Stricter tailored policy solutions of air pollution are urgently needed in China and other countries, especially in well-developed industrial regions, such as upgrading industry structure and promoting green transportation.

BACKGROUND: The effects of COVID-19 lockdown measures on maternal and fetal health remain unclear. We examined the associations of COVID-19 lockdown with gestational length and preterm birth (PTB) in a Chinese population. METHODS: We obtained medical records of 595,396 singleton live infants born between 2015 and 2020 in 5 cities in Guangdong Province, South China. The exposed group (N = 101,900) included women who experienced the COVID-19 Level I lockdown (1/23-2/24/2020) during pregnancy, while the unexposed group (N = 493,496) included women who were pregnant during the same calendar months in 2015-2019. Cumulative exposure was calculated based on days exposed to different levels of emergency responses with different weighting. Generalized linear regression models were applied to estimate the associations of lockdown exposure with gestational length and risk of PTB (< 37 weeks). RESULTS: The exposed group had a shorter mean gestational length than the unexposed group (38.66 vs 38.74 weeks: adjusted ß = - 0.06 week [95%CI, - 0.07, - 0.05 week]). The exposed group also had a higher risk of PTB (5.7% vs 5.3%; adjusted OR = 1.08 [95%CI, 1.05, 1.11]). These associations seemed to be stronger when exposure occurred before or during the 23rd gestational week (GW) than during or after the 24th GW. Similarly, higher cumulative lockdown exposure was associated with a shorter gestational length and a higher risk of PTB. CONCLUSIONS: The COVID-19 lockdown measures were associated with a slightly shorter gestational length and a moderately higher risk of PTB. Early and middle pregnancy periods may be a more susceptible exposure window.

BACKGROUND: In this study, we aimed to analyze the hospitalization costs for immobile patients with hemorrhagic stroke (IHS) or ischemic stroke (IIS) in China and to determine the factors associated with hospitalization costs. METHODS: We evaluated patients with IHS and IIS hospitalized between November 2015 and July 2016 in six provinces or municipality cities of China. Linear regression analysis was used to examine the association with hospitalization costs and predictors. RESULTS: In total, 1573 patients with IHS and 3143 with IIS were enrolled and analyzed. For IHS and IIS, the average length of stay (LoS) was 17.40 ± 12.3 and 14.47 ± 11.55 days. The duration of immobility was 12.11 ± 9.98 and 7.36 ± 9.77 days, respectively. Median hospitalization costs were RMB 47000.68 (interquartile range 19,827.37, 91,877.09) for IHS and RMB 16578.44 (IQR 7020.13, 36,357.65) for IIS. In both IHS and IIS groups, medicine fees accounted for more than one-third of hospitalization costs. Materials fees and medical service fees accounted for the second and third largest proportions of hospital charges in both groups. Linear regression analysis showed that LoS, hospital level, and previous surgery were key determinants of hospitalization costs in all immobile patients with stroke. Subgroup analysis indicated that hospital level was highly correlated with hospitalization costs for IHS whereas pneumonia and deep vein thrombosis were key factors associated with hospitalization costs for IIS. CONCLUSIONS: We found that hospitalization costs were notably higher in IHS than IIS, and medicine fees accounted for the largest proportion of hospitalization costs in both patient groups, perhaps because most patients ended up with complications such as pneumonia thereby requiring more medications. LoS and hospital level may greatly affect hospitalization costs. Increasing the reimbursement ratio of medical insurance for patients with IHS is recommended. Decreasing medicine fees and LoS, preventing complications, and improving treatment capability may help to reduce the economic burden of stroke in China.

The present study attempted to investigate the association among Type D, medication adherence and peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14) in CAPD patients. Patients' medication adherence was assessed by the Medication Adherence Report Scale, retrospectively. Of the 385 CAPD patients who were investigated, 137 (35.6%) patients had a Type D personality. The medication adherence was significantly poorer in the Type Ds compared with that of the non-Type Ds (21.5 ± 2.8 vs. 22.5 ± 2.5 score, p = 0.002). Using multiple linear regression analysis, we found that Type D personality was independently associated with medication adherence (ß = 0.56, p < 0.05). Furthermore, the overall peritonitis-free survival rate of non-Type Ds was significantly higher than that of Type Ds (X2 = 4.41, p = 0.025). Using Cox regression, Type D personality (HR 1.67; 95% confidence interval [CI] 1.07-2.59; p = 0.022) and adherence to bag exchange procedure (HR 1.54; 95% CI 1.11-2.14; p = 0.009) predicted the development of the first peritonitis, even after adjustment for confounders. The current study is the first to identify a strong association among Type D, medication adherence and peritonitis in CAPD patients.

BACKGROUND: Being bedridden, which is a common clinical phenomenon, causes a series of complications related to immobilization. Effective management of immobility complications requires a reasonable allocation of nursing resources. Unit-level evidence about the relationship between nursing resources and immobility complications is lacking. OBJECTIVES: To gain insight into nursing resources in China and explore the relationship between nursing resources and the incidence of major immobility complications among bedridden patients. The major immobility complications included in our study were pressure ulcers, deep vein thrombosis, pneumonia and urinary tract infection. DESIGN: A nationwide, multicenter, cross-sectional survey. SETTING: From November 2015 to June 2016, 18 hospitals (six tertiary and 12 secondary) from six provinces and cities in different geographic regions (eastern, southern, western, northern and central) in China participated in our study. PARTICIPANT: Intensive care units, internal medicine and surgery wards with high proportions of bedridden patients were chosen as investigation sites. Of the total of 23,637 available patients in the selected wards, 19,530 were recruited. METHODS: Data on nursing resources and ward characteristics were collected mainly by questionnaire. The incidence of major immobility complications among bedridden patients was measured by trained investigators. Data on patient characteristics were collected from the patient record system of each hospital. Multilevel regression analysis was used to estimate the impact of nursing resources on the incidence of major immobility complications, adjusting for patient and ward characteristics. RESULTS: The study included 23,637 patients in 213 wards, and 19,530 were recruited. The incidence of the four complications was 0.77% (pressure ulcers), 0.82% (deep vein thrombosis), 3.39% (pneumonia) and 0.86% (urinary tract infection), and the overall incidence of major immobility complications was 5.41%. The incidence of major immobility complications was higher in wards not attaining the target bed-to-nurse ratios than in those that met these criteria (ß = 0.44, 95% confidence interval [CI]: 0.02-0.87; OR = 1.553, 95% CI: 1.002-2.387). The incidence of major immobility complications was negatively associated with the proportion of nurses with intermediate or senior job titles (ß = -2.12, 95% CI: -3.78 to -0.45; OR = 0.120, 95% CI: 0.023-0.638). However, the incidence of major immobility complications was unexpectedly positively associated with the proportion of nurses with a bachelor's degree or higher (ß = 1.06, 95% CI: 0.31-1.81; OR = 2.886, 95% CI: 1.363-6.110). CONCLUSIONS: Sufficient nurse staffing and higher professional titles of nurses might contribute to reducing the incidence of major immobility complications. Nurse experience was not related to the incidence of major immobility complications. However, the association between nurse education level and the incidence of major immobility complications requires further investigation. IMPLICATIONS FOR NURSING MANAGEMENT: More nurses,especially nurses with higher professional titles may reduce the incidence of major immobility complications.

The aim of this study was to assess the prevalence, incidence, and the associated factors of pressure injuries (PIs) among immobile hospitalised patients in China. Being immobile during hospitalisation put these patients at a higher risk of PIs. There is little literature about pressure injury (PI) prevalence or PI incidence in immobile hospitalised patients in hospitals in China. This was a multicentre, cross-sectional, exploratory descriptive study. A total of 23 985 immobile patients were recruited from 25 general hospitals in six provinces of China from November 1, 2015 to March 18, 2016. Information was collected on demographic characteristics, physical assessment information, and treatment and nursing care measures. The PI period prevalence was 3.38%, and the PI cumulative incidence was 1.23%. Most PIs (84.03%) were Stage 1 or Stage 2. A total of 48.22% of PIs occurred in the sacrum or heel region. In the multivariate analysis, the following factors were associated with higher PI prevalence: age, gender, length of immobility, type of hospital, modified Braden Scale score, urinary incontinence, faecal incontinence, low serum albumin, the usage of fixation or restraint devices, and patient's discharge diagnosis (lower limb fracture, malnutrition, and spinal cord injury). PI prevalence for immobile hospitalised patients in the study was lower than those reported in literature. However, because of the large population in China, the number of patients who suffer with PIs can be very high. The relating factors of higher PI prevalence identified in this study were consistent with current literature. Patients with a higher number of these associated factors should be monitored more closely, and preventative measures should be taken to prevent PI occurrence in high-risk populations.

AIMS AND OBJECTIVES: To gain insight into nurses' knowledge and attitudes regarding major immobility complications (pressure ulcers, pneumonia, deep vein thrombosis and urinary tract infections) and explore the correlation of nurses' knowledge and attitudes with the incidence of these complications. BACKGROUND: Immobility complications have adverse consequences, and effective management requires appropriate knowledge, attitudes and skills. Evidence about nurses' knowledge and attitudes regarding immobility complications is lacking. DESIGN: Cross-sectional study. METHODS: A total of 3,903 nurses and 21,333 bedridden patients from 25 hospitals in China were surveyed. Nurses' knowledge and attitudes regarding major immobility complications were assessed using researcher-developed questionnaires. The content validity, reliability and internal consistency of the questionnaires were validated through expert review and a pilot study. The incidence of major immobility complications among bedridden patients from selected wards was surveyed by trained investigators. Correlations between knowledge, attitudes and the incidence of major immobility complications were evaluated with multilevel regression models. RESULTS: Mean knowledge scores were 64.07% for pressure ulcers, 72.92% for deep vein thrombosis, 76.54% for pneumonia and 83.30% for urinary tract infections. Mean attitude scores for these complications were 86.25%, 84.31%, 85.00% and 84.53%, respectively. Knowledge and attitude scores were significantly higher among nurses with older age, longer employment duration, higher education level, previous training experience and those working in tertiary hospitals or critical care units. Nurses' knowledge about pressure ulcers was negatively related to the incidence of pressure ulcers, and attitude towards pneumonia was negatively correlated with the incidence of pneumonia. CONCLUSION: Clinical nurses have relatively positive attitudes but inadequate knowledge regarding major immobility complications. Improved knowledge and attitudes regarding major immobility complications may contribute to reducing these complications. RELEVANCE TO CLINICAL PRACTICE: Nursing managers should implement measures to improve nurses' knowledge and attitudes regarding major immobility complications to reduce the incidence of these complications in bedridden patients.

The previous studies reported Type D was associated with poor quality of life (QoL), increased psychological distress, and impaired health status in cardiac patients. The aim of this study is to assess the relationships among Type D personality, illness perception, social support, and investigate the impact of Type D personality on QoL in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14). Illness perceptions were assessed using the Chinese version of the Brief Illness Perception Questionnaire (B-IPQ). Social support status was assessed by the well-validated social support rating scale (SSRS). Patients' QoL was assessed by using Medical Outcomes Short Form 36 (SF-36), respectively. The Type Ds had significantly lower objective support score (8.18 ± 2.56 vs. 9.67 ± 3.28, p = 0.0001), subjective support score (6.71 ± 2.0 vs. 7.62 ± 1.93, p = 0.0001) and utilization of social support score (6.76 ± 2.0 vs. 7.61 ± 1.94, p = 0.0001) than that of the non-type Ds. Type Ds believed their illness had much more serious consequences (7.67 ± 2.64 vs. 6.27 ± 3.45, p < 0.001), and experience much more symptoms that they attributed to their illness (6.65 ± 2.54 vs. 7.31 ± 2.36, p = 0.023). Significant differences were found between Type Ds and non-Type Ds in PCS (40.53 ± 6.42 vs. 48.54 ± 6.21 p < 0.001) and MCS (41.7 1 ± 10.20 vs. 46.35 ± 9.31, p = 0.012). The correlation analysis demonstrated that Type D was negatively associated with physical component score (PCS) (r = -0.29, p < 0.01), mental component score (MCS) (r = -0.31, p < 0.01), and social support (r = -0.24, p < 0.001). Using multiple linear regression analysis, we found that Type D personality was independently associated with PCS (ß = -0.32, p < 0.001) and MCS (ß = -0.24, p < 0.001). Type D personality was a predictor of poor QoL in CAPD patients. The current study is the first to identify a strong association among Type D, illness perceptions, social support and QoL in CAPD patients. The worse illness perceptions and lower social support level therefore represent possible mechanisms to explain the link between Type D and poor QoL in CAPD patients.

BACKGROUND: Postintensive care syndrome (PICS) is common in critically ill adults who were treated in the intensive care unit (ICU). Although comparative analyses between types of non-pharmacological measures and usual care to prevent PICS have been performed, it remains unclear which of these potential treatments is the most effective for prevention. METHODS: To obtain the best evidence for non-pharmaceutical interventions in preventing PICS, a systematic review and Bayesian network meta-analyses (NMAs) will be conducted by searching nine electronic databases for randomized controlled trials (RCTs). Two reviewers will carefully screen the titles, abstracts, and full-text papers to identify and extract relevant data. Furthermore, the research team will meticulously check the bibliographic references of the selected studies and related reviews to discover any articles pertinent to this research. The primary focus of the study is to examine the prevalence and severity of PICS among critically ill patients admitted to the ICU. The additional outcomes encompass patient satisfaction and adverse effects related to the preventive intervention. The Cochrane Collaboration's risk-of-bias assessment tool will be utilized to evaluate the risk of bias in the included RCTs. To assess the efficacy of various preventative measures, traditional pairwise meta-analysis and Bayesian NMA will be used. To gauge the confidence in the evidence supporting the results, we will utilize the Confidence in NMA tool. DISCUSSION: There are multiple non-pharmacological interventions available for preventing the occurrence and development of PICS. However, most approaches have only been directly compared to standard care, lacking comprehensive evidence and clinical balance. Although the most effective care methods are still unknown, our research will provide valuable evidence for further non-pharmacological interventions and clinical practices aimed at preventing PICS. The research is expected to offer useful data to help healthcare workers and those creating guidelines decide on the most effective path of action for preventing PICS in adult ICU patients.

Introduction: Prone positioning in critical care units may reduce mortality in specific patients who have been admitted with severe conditions. Aim: The current meta-analysis aims to assess the impact of prone compared to supine position besides the safety and tolerability of different enteral feeding techniques in critically ill patients regarding mortality, pneumonia, aspiration, and vomiting. Material and methods: A systematic literature search found 25 relevant trials involving 1984 participants at the start of the study. Statistical analysis using the dichotomous analysis methods was used within the fixed model to calculate the odds ratio (OR) with 95% confidence intervals (CIs). Results: In comparison with the post-pyloric nutrition group, gastric feeding had no significant impact on the mortality rate (OR = 1; 95% CI: 0.76-1.32). While the findings showed a significantly higher incidence of pneumonia with gastric feeding compared with post-pyloric nutrition (OR = 1.92; 95% CI: 1.43--2.57), there was no significant difference regarding pulmonary aspiration and vomiting (OR = 1.41; 95% CI: 0.75-2.65 and OR = 0.92; 95% CI:, 0.66-1.27, respectively). Reflux gastric content was significantly higher with gastric nutrition (OR = 8.23; 95% CI: 2.43-27.89). Conclusions: From reduced gastrointestinal events to significantly higher vomiting rates, prone position during enteral feeding showed mixed effects. Post-pyloric feeding is more tolerated and safer compared with gastric feeding. The mortality rate is not significantly different between techniques.
RESUMO
Background: Although studies have explored the association between triglyceride levels and cognitive function after acute ischemic stroke (AIS), the results have been conflicting. Therefore, the purpose of this study was to investigate the relationship between triglyceride levels and cognitive function after AIS among older adults. Methods: This is an observational cross-sectional study. From November 2022 to June 2023, we consecutively collected patients diagnosed with AIS in China. Triglyceride levels were measured within 24 h of admission. The Mini-Mental State Examination (MMSE) was used to assess cognitive function. Nonlinear associations between triglyceride levels and cognitive function were assessed using smooth curve fitting and threshold effect analysis. Results: In this study, a total of 221 patients (mean ± SD: 70.64 ± 7.43 years) with AIS were consecutively recruited, among whom 144 (65.16%) were male. Among the 221 recruited patients, 102 (46.15%) had cognitive impairment. Triglyceride levels and cognitive impairment were found to have a nonlinear association after controlling for potential confounders, with an inflection point at 0.8 mmol/L. Below the inflection point, triglyceride levels were positively correlated with MMSE scores (ß = 14.11, 95% confidence interval [CI] = 2.33-25.89, P = 0.020). However, above the inflection point, the correlation between MMSE score and triglyceride levels was not statistically significant (ß = 1.04, 95% CI = -1.27 - 3.34, P = 0.380). Conclusion: There is a nonlinear association between triglyceride levels and cognitive function after AIS in older adults. Triglyceride was positively connected with cognitive function when it was less than 0.8 mmol/L.
RESUMO
Background: Pressure injury is a common problem in intensive care units. Critical care nurses play an important role in multidisciplinary teams performing pressure injury treatment. Identifying the clinical status of pressure injury treatment may contribute to improving care quality. Aim: To identify the knowledge, attitudes, and practices regarding pressure injury treatment in critical care nurses. Design: A cross-sectional survey. Methods: Secondary data were extracted from a multicenter clinical trial. Knowledge and attitudes toward pressure injury treatment were assessed through a self-administered eight-item questionnaire. The observed practices were recorded using a case report form. The report was in accordance with the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement. Results: A total of 950 critical care nurses in 15 hospitals from six provinces/municipalities of China were investigated. The mean knowledge score was 2.89 ± 1.16 (95% confidence interval: 2.82-2.97) out of a possible total of 5 points. The correct rates of selecting wound dressings and pain management were 34.4% and 45.6%, respectively. The mean attitude score was 9.07 ± 1.09 (95% confidence interval: 9.00-9.13) out of a possible total of 12 points. A total of 2092 patient days of pressure injury treatment practices were observed and recorded. Repositioning was the most commonly employed treatment measure (98.8%). Foam dressing was the common dressing for stage I (53.6%), stage II (47.5%), and more severe pressure injury (67.9%), including stage III, IV, unstageable, and suspected deep tissue injury. Conclusion: Critical care nurses exhibited a generally low level of knowledge and moderate attitudes regarding pressure injury treatment. Practices of pressure injury treatment were generally acceptable.
RESUMO
BACKGROUND: In this study, we examined the length of stay (LoS)-predictive comorbidities, hospital costs-predictive comorbidities, and mortality-predictive comorbidities in immobile ischemic stroke (IS) patients; second, we used the Charlson Comorbidity Index (CCI) to assess the association between comorbidity and the LoS and hospitalization costs of stroke; third, we assessed the magnitude of excess IS mortality related to comorbidities. METHODS: Between November 2015 and July 2017, 5114 patients hospitalized for IS in 25 general hospitals from six provinces in eastern, western, and central China were evaluated. LoS was the period from the date of admission to the date of discharge or date of death. Costs were collected from the hospital information system (HIS) after the enrolled patients were discharged or died in hospital. The HIS belongs to the hospital's financial system, which records all the expenses of the patient during the hospital stay. Cause of death was recorded in the HIS for 90 days after admission regardless of whether death occurred before or after discharge. Using the CCI, a comorbidity index was categorized as zero, one, two, and three or more CCI diseases. A generalized linear model with a gamma distribution and a log link was used to assess the association of LoS and hospital costs with the comorbidity index. Kaplan-Meier survival curves was used to examine overall survival rates. RESULTS: We found that 55.2% of IS patients had a comorbidity. Prevalence of peripheral vascular disease (21.7%) and diabetes without end-organ damage (18.8%) were the major comorbidities. A high CCI=3+ score was an effective predictor of a high risk of longer LoS and death compared with a low CCI score; and CCI=2 score and CCI=3+ score were efficient predictors of a high risk of elevated hospital costs. Specifically, the most notable LoS-specific comorbidities, and cost-specific comorbidities was dementia, while the most notable mortality-specific comorbidities was moderate or severe renal disease. CONCLUSION: CCI has significant predictive value for clinical outcomes in IS. Due to population aging, the CCI should be used to identify, monitor and manage chronic comorbidities among immobile IS populations.

Importance: The ongoing pandemic of COVID-19 is still affecting our life, but the effects of lockdown measures on gestational diabetes mellitus (GDM) in pregnant women remain unclear. Aim: To investigate the association between COVID-19 lockdown and GDM. Subjects and Methods: Medical records of 140844 pregnant women during 2015-2020 were extracted from 5 hospitals in Guangdong Province, China. Pregnant women who underwent the COVID-19 Level I lockdown (1/23 - 2/24/2020) during pregnancy were defined as the exposed group (N=20472) and pregnant women who underwent the same calendar months during 2015-2019 (1/23 - 2/24) were defined as the unexposed group (N=120372). Subgroup analyses were used to explore the potential susceptible exposure window of COVID-19 lockdown on GDM. Cumulative exposure is quantitatively estimated by assigning different weights to response periods with different exposure intensities. A logistic regression model was used to estimate the association between COVID-19 lockdown exposure and GDM. Results: The rates of GDM in the exposed and unexposed groups were 15.2% and 12.4%, respectively. The overall analyses showed positive associations (odds ratio, OR=1.22, 95%CI: 1.17, 1.27) between lockdown exposure and GDM risk in all pregnant women. More pronounced associations were found in women who underwent the COVID-19 lockdown in their first four months of pregnancy, and the adjusted OR values ranged from 1.24 (95%CI: 1.10, 1.39) in women with 5-8 gestational weeks (GWs) to 1.35 (95%CI: 1.20, 1.52) with < 5 GWs. In addition, we found a positive exposure-response association of cumulative lockdown exposure with the risk of GDM. Conclusions: The COVID-19 lockdown was associated with an increased risk of GDM, and the first four months of pregnancy may be the window for sensitive exposure.

OBJECTIVE: The present study aimed to examine the relationship between dietary patterns and breast cancer risk among Chinese women. METHODS: Four hundred and thirty-eight cases with histologically confirmed primary breast cancer and 438 controls were consecutively recruited. Cases were frequency matched to controls on 5-year age group and rural-urban residence. A validated food frequency questionnaire was used to assess dietary intake by face-to-face interviews. Dietary patterns were identified by factor analysis. Multivariate odds ratios (OR) and 95% confidence interval (CI) were estimated using unconditional logistic regression adjusted for various potential confounders. RESULTS: Two diet patterns were identified: vegetable-fruit-soy-milk-poultry-fish pattern and refined grain-meat-pickle pattern. After adjustment for confounders, a 74% decreased risk was observed among women in the highest quartile of the vegetable-fruit-soy-milk-poultry-fish dietary pattern relative to the lowest quartile (OR = 0.26, 95% CI = 0.17-0.42). The refined grain-meat-pickle pattern was positively associated with breast cancer risk (OR = 2.58, 95% CI = 1.53, 4.34). Women with a high intake of the vegetable-fruit-soy-milk-poultry-fish pattern and a low intake of the refined grain-meat-pickle pattern showed a decreased risk of breast cancer (adjusted OR = 0.26, 95% CI = 0.17-0.41). CONCLUSIONS: These results indicated that a diet characterized by a high consumption of vegetable/fruit/soy/milk/poultry/fish and a low consumption of refined grain/red meat/pickle is associated with a lower risk of breast cancer in Chinese women.

The results of dairy food consumption and breast cancer risk are conflicting, and their relationship has not previously been studied in China. The objective of this study is to examine the association between dairy products, calcium intake, and breast cancer risk among Chinese women. A hospital-based case-control study was conducted among Chinese women in the Guangdong province from June 2007 to August 2008. Four hundred and thirty-eight consecutively recruited cases with primary breast cancer were frequency-matched to 438 controls on age and residence. Dietary intake information was collected by interviewers using a validated food frequency questionnaire. Odds ratios (ORs) and 95% confidence interval (CI) were estimated using unconditional multiple logistic regression adjusted for various potential confounders. We observed a statistically significant inverse association of dietary calcium intake with breast cancer risk, with the adjusted OR (95% CI) of 0.35 (0.22-0.56) comparing the highest with the lowest quartile. No significant association was found between dairy products measured either by dry weight of dairy product or dairy product protein intake and breast cancer risk. Our study supports a protective effect of high intake of dietary calcium on breast cancer risk, and no association with dairy product intake.

Few studies have evaluated the relationship between the consumption of dietary folate and one-carbon metabolism-related nutrients and breast cancer risk defined by oestrogen receptor (ER) and progesterone receptor (PR) status. The objective of the present study was to examine the associations between dietary folate, vitamin B6, vitamin B12, and methionine intake and the risk of breast cancer by ER and PR status among Chinese women in Guangdong. A hospital-based case-control study was conducted from June 2007 to August 2008, with 438 cases and 438 age (5-year interval)- and residence (rural/urban)-matched controls. Dietary intake information was assessed using a validated FFQ administered through a face-to-face interview. Unconditional logistic regression models were used to calculate multivariate-adjusted OR and 95 % CI. A significant inverse association was found between dietary folate and vitamin B6 intake and breast cancer risk. The adjusted OR of the highest v. the lowest quartile were 0·32 (95 % CI 0·21, 0·49; P(trend) < 0·001) for dietary folate and 0·46 (95 % CI 0·30, 0·69; P(trend) < 0·001) for vitamin B6. No associations were observed for vitamin B12 and methionine intake. A significant inverse association between dietary folate intake and breast cancer risk was observed in all subtypes of ER and PR status. These findings suggest that dietary folate and vitamin B6 intakes were inversely associated with breast cancer risk. The inverse association did not differ by ER and/or PR status.

Purpose: Evidence of the impact of nutritional risk on health outcomes and hospital costs among Chinese older inpatients is limited. Relatively few studies have investigated the association between clinical and cost outcomes and nutritional risk in immobile older inpatients, particularly those with neoplasms, injury, digestive, cardiac, and respiratory conditions. Methods: This China-wide prospective observational cohort study comprised 5,386 immobile older inpatients hospitalized at 25 hospitals. All patients were screened for nutritional risk using the Nutrition Risk Screening (NRS 2002). A descriptive analysis of baseline variables was followed by multivariate analysis (Cox proportional hazards models and generalized linear model) to compare the health and economic outcomes, namely, mortality, length of hospital stay (LoS), and hospital costs associated with a positive NRS 2002 result. Results: The prevalence of a positive NRS 2002 result was 65.3% (n = 3,517). The prevalence of "at-risk" patients (NRS 2002 scores of 3+) was highest in patients with cardiac conditions (31.5%) and lowest in patients with diseases of the respiratory system (6.9%). Controlling for sex, age, education, type of insurance, smoking status, the main diagnosed disease, and Charlson comorbidity index (CCI), the multivariate analysis showed that the NRS 2002 score = 3 [hazard ratio (HR): 1.376, 95% CI: 1.031-1.836] were associated with approximately a 1.5-fold higher likelihood of death. NRS 2002 scores = 4 (HR: 1.982, 95% CI: 1.491-2.633) and NRS scores ≥ 5 (HR: 1.982, 95% CI: 1.498-2.622) were associated with a 2-fold higher likelihood of death, compared with NRS 2002 scores <3. An NRS 2002 score of 3 (percentage change: 16.4, 95% CI: 9.6-23.6), score of 4 (32.4, 95% CI: 24-41.4), and scores of ≥ 5 (36.8, 95% CI 28.3-45.8) were associated with a significantly (16.4, 32.4, and 36.8%, respectively) higher likelihood of increased LoS compared with an NRS 2002 scores <3. The NRS 2002 score = 3 group (17.8, 95% CI: 8.6-27.7) was associated with a 17.8%, the NRS 2002 score = 4 group (31.1, 95% CI: 19.8-43.5) a 31.1%, and the NRS 2002 score ≥ 5 group (44.3, 95% CI: 32.3-57.4) a 44.3%, higher likelihood of increased hospital costs compared with a NRS 2002 scores <3 group. Specifically, the most notable mortality-specific comorbidity and LoS-specific comorbidity was injury, while the most notable cost-specific comorbidity was diseases of the digestive system. Conclusions: This study demonstrated the high burden of undernutrition at the time of hospital admission on the health and hospital cost outcomes for older immobile inpatients. These findings underscore the need for nutritional risk screening in all Chinese hospitalized patients, and improved diagnosis, treatment, and nutritional support to improve immobile patient outcomes and to reduce healthcare costs.
