Effect of hydrocolloid dressing on pressure ulcer in patients with non-invasive positive pressure ventilation: A meta-analysis.

This study systematically evaluated the effect of hydrocolloid dressings on facial pressure ulcers in patients receiving non-invasive positive pressure ventilation (NIPPV). The Embase, PubMed, Cochrane Library, CNKI, VIP, Chinese Biomedical Literature Database and Wanfang databases were searched for randomised controlled trials on the use of hydrocolloid dressings in patients receiving NIPPV published from the inception of each database to August 2023. The literature was independently screened, data were extracted by two authors based on the inclusion and exclusion criteria, and the quality of the included literature was assessed. The meta-analysis was performed using Stata 17.0. Thirteen studies including 1248 patients were included, with 639 patients in the intervention group and 609 patients in the control group. Meta-analysis showed that the hydrocolloid dressing significantly reduced the incidence of facial pressure ulcers in patients with NIPPV (odds ratio = 0.16, 95% confidence intervals: 0.11-0.24, p < 0.001). Hydrocolloid dressings are effective in reducing the incidence of facial pressure ulcers in patients receiving NIPPV. However, because of the small number of included studies, this conclusion needs to be confirmed with larger samples and high-quality clinical studies.

The Effect of Diagnostic Blood Loss on Anemia and Transfusion Among Postoperative Patients With Congenital Heart Disease in a Pediatric Intensive Care Unit.

PURPOSE: To evaluate whether diagnostic blood loss can lead to anemia and consequent blood transfusion among postoperative patients with congenital heart disease (CHD) in the pediatric intensive care unit (PICU). DESIGN AND METHODS: This prospective observational study was conducted in a university-affiliated tertiary hospital between January and August 2016. CHD patients aged <12years, undergoing cardiac surgery, with a PICU stay >48h were included (n=205). Multivariate logistic regression analyses were used to determine the effect of diagnostic blood loss on anemia and transfusion. RESULTS: The mean daily phlebotomy volume was 5.40±1.94mL/d during the PICU stay (adjusted for body weight, 0.63±0.36mL/kg/d). Daily volume/kg was associated with cyanotic CHD, Pediatric Risk of Mortality III score, and Pediatric Logistic Organ Dysfunction (PELOD)-2 score. In total, 101 (49.3%) patients presented with new or more severe anemia after admission to PICU, which was not associated with phlebotomy volume. Forty-one (20.0%) children received one or more RBC transfusions during their PICU stay. Multivariate analysis indicated that PELOD-2 score>5, new or more severe anemia, and daily volume/kg of phlebotomy >0.63mL/kg/d were significantly associated with transfusion after 48h of admission to PICU. CONCLUSIONS: Our findings indicate that diagnostic blood loss is not related to postoperative anemia in children with CHD; however, this factor does correlate with blood transfusion, since it somewhat reflects the severity of illness. PRACTICE IMPLICATIONS: Strategies should be applied to reduce diagnostic blood loss, as appropriate.

Midterm results of hybrid perventricular closure of doubly committed subarterial ventricular septal defects in pediatric patients.

OBJECTIVES: To evaluate the safety and efficiency of using hybrid perventricular closure in treating pediatric patients with the doubly committed subarterial ventricular septal defects (VSD). METHODS: Ninety pediatric patients with doubly committed subarterial VSD were enrolled from October 2007 to September 2010 in this retrospective study. Among them, 41 underwent open-heart surgery (surgical group), while 49 underwent perventricular device closure (perventricular group). RESULTS: There was no difference in age (4.36 ± 3.21 vs. 5.82 ± 4.32 years, p > 0.05) between the two groups. VSD diameter was significantly larger in the surgical group than in the perventricular group (5.03 ± 1.31 vs. 6.03 ± 1.94 mm, p < 0.05). There were no major complications such as death, severe valve insufficiency, significant residual shunt, or lethal arrhythmias in two groups. The perventricular group was associated with a significant reduction of transfusion rate (18.4% vs. 97.6%, p < 0.05) as well as mean intensive care unit (ICU) stay (0.97 ± 0.53 vs. 2.78 ± 3.00 days, p < 0.05) in comparison with the surgical group. No difference was noted for complete closure rate between two groups at discharge (97.6% vs. 85.7%, p > 0.05) as well as during follow-up (97.6% vs. 95.9%, p > 0.05). Perventricular device closure was not associated with an increased risk of procedure-induced aortic insufficiency compared with the open-heart surgical group during follow-up (14.3% vs. 14.6%, p > 0.05). CONCLUSIONS: Hybrid perventricular closure may be an alternative to open-heart surgery in selected pediatric patients with doubly committed subarterial VSD.

Multiple geriatric syndromes in community-dwelling older adults in China.

This study aims to assess the prevalence of geriatric syndromes and identify factors associated with multiple geriatric syndromes in community-dwelling older adults in China. We utilized a convenience sampling method to recruit older adults and from one rural and one urban community in Chengdu, China, from October 2022 to March 2023. A total of 706 older adults aged 60 years or older were included. Ten geriatric syndromes were investigated including two mental disorders: depressive symptoms, cognitive impairment; and eight somatic disorders: pain, falls, sleep disturbance, constipation, polypharmacy, multimorbidity, malnutrition and frailty. Multiple geriatric syndromes were defined as an individual having two or more geriatric syndromes. The data obtained were analysed using descriptive statistics. The independent risk factors for multiple geriatric syndromes were assessed using a logistic regression model. This study found that 90.5% of the participants had at least one geriatric syndrome, with 72.8% experiencing multiple geriatric syndromes. The top four geriatric syndromes in our study were polypharmacy (58.5%), malnutrition/at risk of malnutrition (43.1%), multimorbidity (42.1%), and frailty/prefrailty (34.3%). Of the older adults, 368(52.1%) had only somatic disorders, 18(2.5%) had only mental disorders and 253 (35.8%) had somatic-mental disorders. According to the logistic regression analysis, residence, age, marriage, BMI, and self-related health were significantly associated with multiple geriatric syndromes among older adults. This study highlights that multiple geriatric syndromes are prevalent among community-dwelling older adults in China, and underscores the significance of certain demographic factors in their occurrence. Future longitudinal studies are needed to establish the temporal relationship between multiple geriatric syndromes and these demographic factors, as well as to explore causal relationships and effective prevention strategies for geriatric syndrome.

Differences in regional distribution and inequality in health workforce allocation in hospitals and primary health centers in China: A longitudinal study.

BACKGROUND: In 2009, China launched a new round of healthcare reform to provide households with secure, efficient, convenient, equitable and affordable healthcare services. Healthcare reform is underpinned by three critical pillars: the health workforce, funding, and infrastructure, with reform of the health workforce being particularly significant. OBJECTIVE: This study analyses the disparities in regional distribution and the inequity of healthcare workforce allocation across hospitals and primary health centers in China over twelve years. DESIGN: Retrospective longitudinal data from the National Health Statistics Yearbook 2011-2022 and National Statistical Yearbook in China from 2011 to 2022 were collected for analysis. PARTICIPANTS: The focus was on hospitals and primary health centers, explicitly examining their health technician and nursing workforce. METHODS: The research utilized four key indicators of the healthcare workforce to evaluate the distribution of health resources between hospitals and primary health centers. Furthermore, the Gini coefficient and Theil index were employed to assess the inequality in allocating the health workforce. RESULTS: Between 2010 and 2021, there was a nationwide increase in the ratio of health workers per 1000 population in hospitals and primary health centers. It is noted that rural districts had higher ratios than urban districts in terms of the number of health technicians and nurses per 1000 population, whether in hospitals or primary health centers; western districts had higher ratios than eastern and central districts did. In the same year, at different levels of medical institutions, the Theil indices of health technicians and nurses in hospitals were lower than those in primary health centers in terms of both demographic and geographical dimensions. Regarding the allocation of the health workforce by population, the Gini coefficient remained below 0.3, while for geographical allocation, it exceeded 0.4. CONCLUSIONS: This study analyzed the temporal trends and inequality of health-resource allocation at the hospital and primary health center levels in China, noting trends of improvements in the quantity and inequality in health workforce allocation from 2010 to 2021, suggesting the success of the government's efforts to advance healthcare reform since 2009. The allocation of health workforce based on population exhibits greater fairness compared to geographical distribution.

Association of daily health behavior and activity of daily living in older adults in China.

This study aims to describe the activity of daily living (ADL) situation and determine the relationship between health behavior and ADL among older adults in China. A cross-sectional, observational study was conducted in one urban community and one rural community in Chengdu (a city located in Southwest China), China, from October 2022 to March 2023. A total of 706 older adults were included in this study. The associations between health behaviour and ADL were assessed by logistic regression model. Of the 706 older adults, 169 (23.9%) were disabled in ADL. According to the logistic regression analysis, age (60-69 years old: OR = 0.015, 95% CI 0.007 to 0.035, P < 0.001; 70-79 years old: OR = 0.116, 95% CI 0.060 to 0.227, P < 0.001), resident(OR = 0.568, 95% CI 0.330 to 0.976, P = 0.041), chronic disease (0 type: OR = 0.023, 95% CI 0.001 to 0.379, P = 0.008; 1-4 types: OR = 0.357, 95% CI 0.219 to 0.582, P < 0.001), no exercise (OR = 4.562, 95% CI 2.263 to 8.026, P < 0.001), and physical examination (OR = 2.217, 95% CI 1.294 to 3.496, P = 0.003) were significantly associated with ADL among older adults in Southwest China. This study showed that older adults had a higher ADL disability ratio. Age, resident, chronic disease, exercise and physical examination were associated with ADL among older adults. The study indicates that medium/high exercise maybe a protective factor for older adults, and nursing staff can encourage older adults to exercise when carrying out primary prevention measures. The government and public health institutions should give special attention to older adults and help them to acquire the habit of having an annual physical examination.

[Application of peripherally inserted central catheter for parenteral nutrition in critically ill neonates].

OBJECTIVE: To apply peripherally inserted central catheter (PICC) in critically ill neonates who require long-term parenteral nutrition. METHODS: A retrospective review of 98 critically ill neonates who had a PICC inserted and received long-term parenteral nutrition from March to December 2011 was performed. RESULTS: The PICC insertion succeeded in 74.5% (73/98) of the cases at the first attempt. The catheter remained for an average of (19.7 +/- 2.0) days. Of the 98 cases, 92 underwent planned extubation after enteral nutrition was fully established; 10 developed complications within the follow-up period of 956 days. The PICC-associated complications occurred at a rate of 10. 5 per 1000 catheter-days, including infection (n=0), phlebitis (n=1), accidental dislodgement (n=3), catheter occlusion (n=3), and hemorrhage in puncture point (n=3). CONCLUSION: PICC can be used as a safe venous access for critically ill neonates for long-term parenteral nutrition. PICC-associated complications can be reduced through improving nursing skills, especially for catheter-related infection.

[Establishment and evaluation of extracorporeal circulation model in rats].

OBJECTIVE: To establish an extracorporeal circulation (ECC) rat model, and evaluate the inflammatory response and organ injury induced in the model. METHODS: SD rats were anesthetized and cannulated from right common carotid artery to left femoral vein to establish the bypass of extracorporeal circulation. Then the rats were randomly divided into ECC group and sham group. The rats in ECC group were subjected to extracorporeal circulation for 2 hours and then rest for 2 hours, while the rats in sham group were only observed for 4 hours without extracorporeal circulation. After that, blood routine examination, blood gas analysis, the measurement of pro-inflammatory factors in bronchoalveolar lavage fluid and lung tissue were performed to evaluate the lung injury induced by ECC. Circulating endothelial cells were also calculated by flow cytometry to assess the vascular endothelial injury. RESULTS: At 2 hours after ECC, red blood cell counts in both groups kept normal, while leukocyte and neutrophil counts, plasmatic tumor necrosis factor-a level and neutrophil elastase level, circulating endothelial cells in the rats of ECC group were significantly higher than those in sham group. Tumor necrosis factor-alpha in bronchoalveolar lavage fluid and water content in lung of the ECC rats were also significantly higher, while the oxygenation index was significantly lower. Neutrophil infiltration was also observed in lung tissues with increased thickness of alveolar membrane in ECC group. CONCLUSION: The ECC model established from right common carotid artery to left femoral vein in our study can successfully induce systemic inflammatory response, and acute lung injury associated with inflammation.

Preoperative Hemoglobin Level, Oxygen Saturation and Postoperative Outcomes in Children With Cyanotic Congenital Heart Disease: A Propensity-Score Matching Analysis.

BACKGROUND: The optimal preoperative hemoglobin (Hb) level is difficult to define in children with cyanotic congenital heart disease (CHD) due to hypoxemia-induced secondary erythrocytosis. This retrospective study integrated preoperative Hb and pulse oxygen saturation (SpO2) using the product of Hb × SpO2 to predict postoperative outcomes in children with cyanotic CHD. PATIENTS AND METHODS: Children aged <18 years undergoing cardiac surgery with cyanotic CHD were included. The cutoff value of Hb × SpO2 was the age-adjusted lower limit of normal Hb (aaHb) in healthy children. The main outcomes were in-hospital death and the composite outcome of severe postoperative events. Multivariate logistic regression analysis and propensity score matching analysis were used to adjust for important confounders. RESULTS: The presence of preoperative Hb × SpO2 < aaHb was observed in 21.6% of cyanotic children (n = 777). Children with Hb × SpO2 < aaHb had higher in-hospital mortality (12.5% vs. 4.6%, P < 0.001) and composite outcome incidence (69.6% vs. 32.3%, P < 0.001) than those with Hb × SpO2 ≥ aaHb. After propensity score matching, 141 pairs of children were successfully matched. Multivariate analysis showed that preoperative Hb × SpO2 < aaHb was significantly associated with the composite outcome in the entire population (odds ratio = 4.092, 95% confidence interval = 2.748-6.095, P < 0.001) and the matched cohorts (odds ratio = 2.277, 95% confidence interval = 1.366-3.795, P = 0.002). CONCLUSION: Our results suggest that a preoperative Hb × SpO2 value below the lower limit of normal hemoglobin is a prognostic factor in cyanotic children undergoing cardiac surgery and is a potential criterion to evaluate preoperative anemia in this population.
