Iatrogenic skin injuries in infants admitted to neonatal intensive care units: An investigation in 22 Chinese units. J Tissue Viability 2024:S0965-206X(24)00033-0. [PMID: 38561302 DOI: 10.1016/j.jtv.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 02/28/2024] [Accepted: 03/09/2024] [Indexed: 04/04/2024]
Abstract
OBJECTIVE To investigate the incidence of iatrogenic skin injuries in neonates across 22 neonatal intensive care units (NICUs) in China. DESIGN Prospective study. SETTING 22 NICUs in China. PATIENTS Infants admitted to NICU. INTERVENTIONS None. MEASUREMENTS The "Iatrogenic Skin Injuries Data Collection Form of infants" were used to collect the data during hospitalization. MAIN RESULTS A total of 8126 neonates who were hospitalized in 22 tertiary hospitals across 15 provinces, cities, and autonomous regions of China between December 1, 2019 and January 31, 2020 were analyzed. Five hundred and twenty-one infants had iatrogenic skin injuries, including 250 with diaper dermatitis (47.98%), 70 with physicochemical factor-related skin lesions (PCFRSIs) (13.44%), 81 with medical device-related pressure injuries (MDRPIs) (15.55%), and 69 with medical adhesive-related skin injuries (MARSIs) (13.24%), accounting for 91% of the total number of iatrogenic injuries. Among these, diaper dermatitis was closely related to the skin and feeding status. Furthermore, the risk was higher among neonates who had skin damage upon admission or were already fully fed orally. The influencing factors of MDRPIs and MARSIs were similar. They were negatively associated with gestational age and birth weight, and were closely related to the presence of various tubes. CONCLUSIONS Diaper dermatitis, PCFRSIs, MDRPIs, and MARSIs were the four common types of iatrogenic skin injuries in newborns. The various types of iatrogenic skin injuries were influenced by varying factors. Specialized nursing measurements can reduce the likelihood of these injuries.

Abstract
PURPOSE/OBJECTIVE(S) Dual-energy CT can be used to optimize radiation treatment. Recently, deep learning has been demonstrated to synthesize high-energy CT images from low-energy ones for dose reduction and lower CT system burden. As the state-of-the-art deep learning architecture, the computation burden of Transformer increases quadratically with the feature size, making the model training resource-demanding or even infeasible. Here, we introduce an efficient transformer for the balance between CT image synthesis quality and computational burden. MATERIALS/METHODS The model is a U-shape deep neural network with encoders and decoders built by Transformer blocks. The model input is low-energy 100kVp CT image and the output is high-energy 140kVp one. Each block has a Self Channel Correlation Unit (SCCU) and a Self Spatial Attention Unit (SSAU). Local shortcuts are applied for both units. Under-sampling operation achieved by pixel shuffling is used to obtain multi-scale feature maps, and the transformer block is applied on each feature scale. Symmetric skip connection sending features from shallow layers to deep layers, thus an additional 1 × 1 convolution is used for feature fusion in each decoder. In a SCCU, the feature is first mapped to one Query, one Key, and one Value. Then the Query and the Key tensors perform matrix multiplication to compute cross covariance of feature channels. The channel correlation score can be obtained by normalization of the covariance, and it is used to weight the Value tensor. As a result, the model complexity only increases linearly with the feature size. Besides the channel weighting, we enhance spatial information using SSAU, where the feature is mapped to two tensors. One tensor after activation is used to point-wisely calibrate another tensor. Additional Transformer blocks are cascaded to the last decoder for feature refinement. Because of the structure similarity of low- and high-energy CT images, a global shortcut is used to ease model training. Clinical iodine contrast-enhanced dual energy CT image datasets of 19 patients are used in this study. The dual-energy scanning is performed by a SOMATOM Definition Flash DECT scanner. We split the datasets into training dataset of 15 patients, validation dataset of 1 patient, and testing dataset of 3 patients. The image size is 512 × 512 with pixel size 0.5 × 0.5 mm2. RESULTS The U-Net model with 1.95M parameters and 44.87G FLOPS achieved the averaged PSNR value of 44.55 dB (s.t.d. 1.34) and averaged RMSE value of 0.0060 (s.t.d. 0.001). In comparison, our efficient Transformer with 1.408M parameters and 31.375G FLOPS achieved the averaged PSNR value of 44.78 dB (s.t.d. 1.37) and RMSE value of 0.0059 (s.t.d. 0.001), demonstrating our model has better performance with small model size and less computation. CONCLUSION The efficient Transformer model allows high-resolution CT image synthesis with small model scale and computation burden from low-energy CT image.

[PMID: 37095429 PMCID: PMC10123578 DOI: 10.1186/s12884-023-05581-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 04/07/2023] [Indexed: 04/26/2023] Open
Abstract
BACKGROUND In most areas of China, mothers typically do not participate in early care of preterm infants in NICU. This study aims to examine the early experience of mothers of preterm infants participating in skin-to-skin contact combined with non-nutritive comfort sucking in China. METHODS This qualitative research study used one-on-one, face-to-face, semi-structured in-depth interviews. Eighteen mothers who participated in early skin-to-skin contact combined with non-nutritive comfort sucking were interviewed in the NICU of a tertiary children's hospital in Shanghai between July and December 2020. Their experiences were analyzed using the inductive topic analysis method. RESULTS Five themes about skin-to-skin contact combined with non-nutritive comfort sucking were identified, including alleviation of maternal anxiety and fear during mother infant separation, reshaping the maternal role, promotion of active breast pumping, enhances the mother's willingness to actively breast feed and building the maternal confidence in baby care. CONCLUSION Skin-to-skin contact combined with non-nutritive comfort sucking in the NICU can not only enhance the identity and responsibility of the mother's role, but also provide non-nutritive sucking experience for promoting the establishment of oral feeding in preterm infants.

Abstract
BACKGROUND Intensive care is of great significance for very low birth weight infants (VLBWI). The Yangtze River Delta is the most ecomonically developed area in China. However, there are few data on the care practices and survival of VLBWI in this region. OBJECTIVES To investigate the prevalence, care practices and motality of VLBWI in Yangtze River Delta in China. METHODS A multi-center retrospective investigation study was conducted at five tertiary hospitals within the Yangtze River Delta in China from January to December 2017. Clinical data included the general characteristics of the infants and the mothers, clinical prognosis, care practices in NICUs was collected by trained research members. RESULTS During the study period, 1059 VLBWIs were included. Infants with birth weight < 750 g, 750-1000 g, 1000-1250 g and 1250-1500 g accounted for 2.3, 14.9, 34.8 and 47.8%, respectively. Premature rupture of membranes (17.8%) was the main cause of premature delivery. The catheterization rates of umbilical vein catheterization (UVC) and peripherally inserted central catheter (PICC) were 25.0 and 64.4%, respectively. The duration of parenteral nutrition was 27.0 ± 19.5 d, the meantime of feeding tube indwelling was 36.2 ± 24.2 d. The corrected gestational age of the infants who reached full oral feeding was 35.8 ± 2.7 weeks. The breast feeding rate in the investigated infants was 61.9%. The mortality rate of preterm infants was 3.4%. The incidence of main complications BPD, PDA, ROP, NEC and sepsis were 24.9, 29.9, 21.7, 9.4 and 13.3% respectively. CONCLUSIONS Maternal and infant care practices need to be improved in the very preterm births. This study provides a baseline for the improvement in the further study.

Abstract
Due to the lack of enough physical or suck central pattern generator (SCPG) development, premature infants require assistance in improving their sucking skills as one of the first coordinated muscular activities in infants. Hence, we need to quantitatively measure their sucking abilities for future studies on their sucking interventions. Here, we present a new device that can measure both intraoral pressure (IP) and expression pressure (EP) as ororhithmic behavior parameters of non-nutritive sucking skills in infants. Our device is low-cost, easy-to-use, and accurate, which makes it appropriate for extensive studies. To showcase one of the applications of our device, we collected weekly data from 137 premature infants from 29 week-old to 36 week-old. Around half of the infants in our study needed intensive care even after they were 36 week-old. We call them full attainment of oral feeding (FAOF) infants. We then used the Non-nutritive sucking (NNS) features of EP and IP signals of infants recorded by our device to predict FAOF infants' sucking conditions. We found that our pipeline can predict FAOF infants several weeks before discharge from the hospital. Thus, this application of our device presents a robust and inexpensive alternative to monitor oral feeding ability in premature infants.

Objective: To apply artificial intelligence technology in clinical real-world data of patients with primary hepatocellular carcinoma, explore the precise treatment of disease and build up artificial intelligence-based clinical decision support system. Methods: A total of 5 642 patients with primary hepatocellular carcinoma admitted to West China Hospital from July 2004 to June 2016 with complete follow-up records were included in the study. A merged model composed of multiple sub-classifiers was adopted to calculate therapy recommendation coefficient, and receiver operator characteristic curve was analyzed. Survival risk and recurrence risk were predicted by DeepSurv algorithm, and Kaplan-Meier survival curves were further compared among low, middle and high risk groups. Siamese-Net was applied to find similar patients. Results: The Top-1 and Top-2 accuracy of therapy recommendation coefficient reached 82.36% and 94.13% respectively. In internal verification of West China Hospital, the above-mentioned value reached 95.10% in accordance with multi-disciplinary team results. The C-index derived from survival risk model was 0.735 (95%CI:0.70-0.77), and the difference of Kaplan-Meier in pairwise comparison was of statistical significance under log-rank test (P<0.001). Meanwhile, the C-index derived from recurrence risk model was 0.705 (95%CI:0.68-0.73), and the difference of Kaplan-Meier in pairwise comparison was of statistical significance under log-rank test (P<0.001). Conclusions: The artificial intelligence-based clinical decision support system for primary hepatocellular carcinoma has can accurately make therapy recommendation and prognosis prediction for primary hepatocellular carcinoma.

Abstract
One of the challenges in examining development of newborns is measuring activities which are correlated to their health. Oral feeding is the most important factor in an infant's healthy development. Here, we present a new device that can measure intraoral and expression pressures produced in a newborn's mouth by non-nutritive sucking. We then develop a method to extract time-intervals that a sucking has occurred. To show an application of this device, we use Apgar score as a reference of the general health of newborns, and we evaluate these scores with the non-nutritive sucking patterns demonstrated by the infants. We show that for the pairs of infant with the same background but different Apgar scores, those with lower Apgar scores have lower pressure amplitudes while sucking. Importance of non-nutritive sucking skills in the development of newborns and ease of using our device make it useful for clinical studies of infantile health.

Abstract
Objectives: To investigate the current practices of oral feeding difficulties facing high-risk infants in Chinese NICUs. Methods: A questionnaire to survey infant oral feeding practices was distributed to 100 level II and III Chinese neonatal intensive care units (NICUs). Results: Responses were obtained from 88 NICUs. No Units had any structured guidelines regarding the management of infant oral feeding as they transitioned from tube to independent oral feeding. In 54 (61.4%) NICUs, nurses and physicians made shared decisions on when oral feeding were to be initiated. Fifty-four (61.4%) and 22 (25.0%) NICUs used postmenstrual age (PMA) or weight at PMA as a criterion for initiating oral feedings, respectively. The top three criteria to determine introduction of oral feeding were severity of disease, presence of sucking reflex, and trial feeding success. Adverse events were used by 78 Units as indices of oral feeding difficulty. Twenty (22.7%) and 25 (28.4%) Units had access to occupational therapists or nurses who provided oral motor interventions during feeding, i.e., oral support (chin and cheek support, aid to deglutition), non-nutritive sucking with pacifier, and oral stimulation. Conclusions: The management of oral feeding issues in NICUs vary widely in China in relation to the assessment of readiness to oral feeding, daily oral feeding practices and interventions used by staff. It is proposed that an educational program focused on the physiology of infant oral feeding, available evidence-based tools and interventions would assist NICU caregivers develop structured guidelines to improve infants' safe and efficient attainment of independent oral feeding.

Abstract
Objective: To investigate the early diagnosis and treatment for burn complicated with severe paroxysmal sympathetic hyperactivity (PSH). Methods: Medical records of patients with burn complicated with severe PSH, admitted to our department from April 2016 to March 2019 and meeting the inclusion criteria were analyzed retrospectively. There were 4 males and 1 female, aged 17 months to 39 years, with an average of (21±16) years. During occurrence of PSH, the vital signs of patients were routinely monitored and oxygen were given. Other treatment included central venous catheterization and infusion of electrolyte solution, infusion of plasma according to patients' condition, use of opioid analgesics and benzodiazepine sedatives, physical cooling and drug cooling, and establishment or maintenance of artificial airway and use of ventilator. Heart rate was controlled below 120 beats per minute in adults and 140 beats per minute in children with comprehensive treatment dominated by analgesia and sedation. Besides, single or multiple vasoactive agents, even in large doses were used to maintain normal blood pressure of patients. The occurrence characteristics, time, and treatment outcome of PSH were analyzed. Results: PSH happened rapidly, with a sharp increase in several minutes to dozens of minutes. Five patients were with symptoms such as high body temperature, shortness of breath, very fast heart rate, normal or elevated systolic blood pressure, hyperhidrosis, and dystonia at the onset. The symptoms occurred simultaneously or successively. According to the Clinical Feature Scale, the above-mentioned 6 indexes achieved the highest score of 3 points except of systolic blood pressure. Four patients showed dilated pupils and impaired consciousness. Among the patients, PSH occurred in the acute exudation stage in 3 patients, in the fluid reabsorption stage in 1 patient, and in the late repair stage in 1 patient. PSH of patients lasted for 3 hours to 12 days. The symptoms of 4 patients were effectively controlled, and 1 patient died of deterioration. No PSH occurred in the cured patients during follow-up of 3 to 14 months. Conclusions: Burn complicated with PSH can occur at any time before wound repair and in patients with different injury conditions. The causes of PSH include sudden burn, persistent pain, fright and fear, strange environment, low blood volume, and other adverse stimuli, and PSH is more likely to occur in children with underdeveloped brain function. Intravenous infusion of analgesics sedatives, physical therapy and medication to lower body temperature, stabilizing blood pressure and respiration are effective measures to treat PSH. PSH should be distinguished from the common complications of burns, such as sepsis, cerebral edema, hyperpyretic convulsion, transfusion response, stress disorder, etc.

Abstract
One severely burned patient, caused by heat lead slag and combined with shock, was hospitalized in our burn unit on 2nd June, 2016. The patient received treatments including anti-shock, intensive care, anti-infection, and organ protection. On post injury day 16, the patient suffered outbreak of acute hemorrhagic necrotizing enteritis after eating dumplings. Plasma and albumin were given, octreotide was intravenously infused to inhibit the secretion of intestinal fluid, the broad-spectrum antibiotics were used for anti-infection, abdominal puncture and drainage were performed, sodium tanshinone ⅡA sulfonate was applied to improve the intestinal microcirculation, ulinastatin was applied to alleviate inflammatory reaction, somatostatin was given to reduce intestinal bleeding, and voriconazole was given for antifungal treatment. The patient gradually recovered and was finally cured and discharged. Among critically ill patients, gastrointestinal tract is not only the initiating organ of sepsis, but also one of the target organs which can be easily damaged during sepsis. This case reminds us the importance of gastrointestinal management in severely burned patients.

Abstract
Objective: To evaluate the reliability and validity of the Chinese version of the uterine fibroid symptom and health-related quality of life (UFS-QOL) in patients with uterine fibroid. Methods: The original English UFS-QOL was translated into Chinese and linguistically validated following the cross-cultural adaptation of health-related quality of life measures. Patients recruited randomly from Peking Union Medical College Hospital from June 2013 to December 2016 were scheduled for two visits with 2 weeks apart, and they were surveyed through the Chinese version of UFS-QOL and short-form 12-item health survey (SF-12). The reliability and validity of the Chinese version of UFS-QOL were evaluated. Results: A total of 190 uterine fibroid patients who met the criteria participated this study. The Chinese version of UFS-QOL had a high internal consistency (Cronbach's α, uterine fibroid symptom severity scale:0.912, health-related quality of life scale: 0.976) and high test-retest reliability (intraclass correlation coefficient, 0.572-0.951, P<0.01). The symptom severity scores and SF-12 scores were negatively correlated (r=-0.813, P<0.01); the health-related quality of life scores and SF-12 scores were positively correlated (r=0.620, P<0.01). The factor analysis showed good construct validity. Conclusion: Psychometric testing supports the reliability and validity of the Chinese version of UFS-QOL as an disease-specific measure of health-related quality of life.
