Abstract
BACKGROUND Malnutrition is a critical issue among older inpatients, yet limited large-scale research related to this issue has been conducted in China. This study aimed to examine the nutritional status and support of older inpatients in China, assess the associations between disease categories and malnutrition on admission, and explore effective nutritional intervention. METHODS A total of 24,139 older participants from the China Nutrition Fundamental Data 2020 Project were included. Malnutrition was measured by the Global Leadership Initiative on Malnutrition criteria. Adjusted odds ratios (aORs) were calculated using logistic analysis. RESULTS The overall frequency of malnutrition on admission was 18.9%. Participants with infections were more likely to have malnutrition (aOR = 1.929, 95% CI 1.486-2.504). Risks that were also noted for malnutrition included neoplasms (aOR = 1.822, 95% CI 1.697-1.957), hemic and lymphatic diseases (aOR = 1.671, 95% CI 1.361-2.051), nervous system diseases (aOR = 1.222, 95% CI 1.126-1.326), respiratory diseases (aOR = 1.613, 95% CI 1.490-1.746), and digestive system diseases (aOR = 1.462, 95% CI 1.357-1.577). Further, 32.26% inpatients with malnutrition during hospitalization didn't receive nutritional support. Oral nutrition supplements, enteral tube feeding, and parenteral nutrition were associated with stable or improved nutritional status. CONCLUSIONS Older inpatients were at a high risk for malnutrition but did not receive adequate nutritional intervention. More resources and attention need to be devoted to the nutritional status of older inpatients and targeted nutritional support.

Abstract
INTRODUCTION Acute respiratory infection (ARI) contributes to significant mortality and morbidity worldwide and is usually caused by a wide range of respiratory pathogens. This study aims to describe the performance of QIAstat-Dx® Respiratory Panel V2 (RP) and RespiFinder® 2SMART assays for respiratory pathogens detection. MATERIALS AND METHODS A total of 110 nasopharyngeal swabs (NPS) were collected from children aged one month to 12 years old who were admitted with ARI in UKMMC during a one-year period. The two qPCR assays were conducted in parallel. RESULTS Ninety-seven samples (88.2%) were positive by QIAstat-Dx RP and 86 (78.2%) by RespiFinder assay. The overall agreement on both assays was substantial (kappa value: 0.769) with excellent concordance rate of 96.95%. Using both assays, hRV/EV, INF A/H1N1 and RSV were the most common pathogens detected. Influenza A/H1N1 infection was significantly seen higher in older children (age group > 60 months old) (53.3%, p-value < 0.05). Meanwhile, RSV and hRV/EV infection were seen among below one-year-old children. Co-infections by two to four pathogens were detected in 17 (17.5%) samples by QIAstat-Dx RP and 12 (14%) samples by RespiFinder, mainly involving hRV/EV. Bacterial detection was observed only in 5 (4.5%) and 6 (5.4%) samples by QIAstat-Dx RP and RespiFinder, respectively, with Mycoplasma pneumoniae the most common detected. CONCLUSION The overall performance of the two qPCR assays was comparable and showed excellent agreement. Both detected various clinically important respiratory pathogens in a single test with simultaneous multiple infection detection. The use of qPCR as a routine diagnostic test can improve diagnosis and management.

Simultaneous alleviation of Cd availability in contaminated soil and accumulation in rice (Oryza sativa L.) by Fe-Mn oxide-modified biochar. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 858:159730. [PMID: 36306853 DOI: 10.1016/j.scitotenv.2022.159730] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 10/20/2022] [Accepted: 10/22/2022] [Indexed: 06/16/2023]
Abstract
Fe-Mn oxide-modified biochar (BC-FM) was used to remediate Cd-contaminated soil and mitigate Cd accumulation in rice. The roles of Fe and Mn in soil Cd immobilization and in controlling Cd uptake by rice were investigated via X-ray photoelectron spectroscopy (XPS) characterization and chemical analysis. Fe and Mn loaded on BC-FM increased the removal efficiencies of CaCl2 extractable Cd in soil and Cd in pore water compared to those in only biochar (BC)-treated soil, with maximum removal rates at 67.9 % and 77.8 %, respectively. The XPS results indicated that the redox reactions of the Fe-Mn oxides on BC-FM surface affected Cd immobilization in the soil. The Fe (II/III) components on BC-FM were primarily converted to Fe3O4 in the soil system, which may form stable complexes with Cd2+ (Fe-O-Cd) during the entire rice growth period, and Cd may be bound to MnO or Mn2O3 in the form of CdMn2O4. The excellent adsorption performance of BC-FM enhanced by Fe-Mn oxides reduced the available Cd in the soil and stimulated Fe and Mn transport in rice, thereby inhibiting Cd accumulation in the aerial parts of rice. Cd concentrations in brown rice under BC-FM treatments reached the national safety standard (0.2 mg/kg, GB2762-2017). And BC-FM significantly increased the biomass of brown rice with a maximum rate of 26.8 %. These findings suggest that BC-FM could be used as an efficient material for Cd-contaminated soil remediation, and Fe-Mn plays important role in immobilizing Cd in soil and reducing Cd transport in rice.

Enhancing Cd(II) adsorption on rice straw biochar by modification of iron and manganese oxides. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 300:118899. [PMID: 35085653 DOI: 10.1016/j.envpol.2022.118899] [Citation(s) in RCA: 42] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 01/04/2022] [Accepted: 01/22/2022] [Indexed: 06/14/2023]
Abstract
Metal oxide-modified biochar showed excellent adsorption performance in wastewater treatment. Iron nitrate and potassium permanganate were oxidative modifiers through which oxygen-containing groups and iron-manganese oxides could be introduced into biochar. In this study, iron-manganese (Fe-Mn) oxide-modified biochar (BC-FM) was synthesized using rice straw biochar, and the adsorption process, removal effect, and the mechanism of cadmium (Cd) adsorption on BC-FM in wastewater treatment were explored through batch adsorption experiments and characterization (SEM, BET, FTIR, XRD, and XPS). Adsorption kinetics showed that the maximum adsorption capacity of BC-FM for Cd(II) was 120.77 mg/g at 298 K, which was approximately 1.5-10 times the amount of adsorption capacity for Cd(II) by potassium-modified or manganese-modified biochar as mentioned in the literature. The Cd(II) adsorption of BC-FM was well fit by the pseudo-second-order adsorption and Langmuir models, and it was a spontaneous and endothermic process. Adsorption was mainly controlled via a chemical adsorption mechanism. Moreover, BC-FM could maintain a Cd removal rate of approximately 50% even when reused three times. Cd(II) capture by BC-FM was facilitated by coprecipitation, surface complexation, electrostatic attraction, and cation-π interaction. Additionally, the loaded Fe-Mn oxides also played an important role in the removal of Cd(II) by redox reaction and ion exchange in BC-FM. The results suggested that BC-FM could be used as an efficient adsorbent for treating Cd-contaminated wastewater.

Abstract
Objective: To establish the animal model of subchronic manganism, and to explore the effect of manganese on neurofunction of rats and the protective effect of curcumin on neurotoxicity of manganism rats. Methods: From July to December 2019, 80 SPF male SD rats were divided into 8 groups according to body weight by random number table method, which were blank control group, low, middle and high dose manganese exposure group, low, middle and high dose curcumin antagonistic group and curcumin group, with 10 rats in each group. The low, middle and high dose manganese groups were given intraperitoneal injection of 5 mg/kg, 10 mg/kg and 15 mg/kg MnCl(2)·4H(2)O respectively. The low, middle and high dose curcumin antagonistic groups were given 100 mg/kg, 200 mg/kg and 400 mg/kg curcumin orally along with 15 mg/kg MnCl(2)·4H(2)O intraperitoneal injection. Curcumin group was given 400 mg/kg curcumin orally. The rats were exposed to 5 days a week, once a day for 16 weeks. After exposure, neurobehavioral tests (balance beam test, Morris water maze, passive avoidance test) were carried out in each group. Hippocampus tissues were taken for pathological examination and oxidative stress indexes were detected. Results: The balance beam test results showed that, compared with the blank control group, the scores of balance beam of the rats in the middle and high dose manganese exposure groups increased (P<0.05) . Compared with the high dose manganese exposure group, the balance beam scores of the low, middle and high dose curcumin antagonistic groups were decreased (P<0.05) .The results of Morris water maze showed that, compared with the blank control group, the escape latency of middle and high dose manganese exposure groups was prolonged from the third day (P<0.05) , and the average number of crossing the platform area of each manganese exposure group was decreased (P<0.05) .Compared with the high dose manganese exposure group, the escape latency of the middle and high dose curcumin antagonistic groups was shortened (P<0.05) , and the average number of crossing the original platform was increased (P<0.05) . The results of passive avoidance test show that, compared with the blank control group, the number of errors were increased in middle and high dose manganese exposure groups (P<0.05) . Compared with the high dose manganese exposure group, the number of errors in the passive avoidance test in the middle and high dose curcumin antagonistic groups were decreased (P<0.05) . Pathological examination showed that the rats treated with manganses had different degrees of degeneration and necrosis of nerve cells, and the structure of nerve cells was blurred and the number of nerve cells decreased. The above phenomena were improved after curcumin antagonism. The results of oxidative stress index showed that, compared with blank control group, the activity of superoxide dismutase (SOD) decreased and the content of malondialdehyde (MDA) increased in the hippocampus of rats exposed to middle and high dose of manganese (P<0.05) . Compared with the high dose manganese exposure group, the SOD activity increased and the MDA content decreased in the middle and high dose antagonist group (P<0.05) . Conclusion: Subchronic manganese exposure can reduce the balance function, learning and memory ability of rats, and damage the hippocampal nerve cells in oxidative stress state. Curcumin can improve the balance function and learning and memory ability of rats with manganese poisoning, improve the hippocampal nerve damage caused by manganese exposure, and has a certain protective effect on manganese induced neurotoxicity.

Abstract
Electrocatalytic reduction of CO2 is one of the most attractive approaches for converting CO2 into valuable chemical feedstocks and fuels. This work reports a catalyst comprising graphdiyne-decorated bismuth subcarbonate (denoted as BOC@GDY) for efficient electroreduction of CO2 to formate. The BOC@GDY shows a stable current density of 200 mA cm-2 at -1.1 V in a flow cell configuration, with a faradaic efficiency of 93.5% for formate. Experimental results show that the synergistic effect in BOC@GDY is beneficial for the CO2 adsorption affinity, the reaction kinetics and the selectivity for formate. In addition, in-situ X-ray absorption and Raman spectroscopy indicate that the electron-rich GDY could facilitate the reduction from Bi(III) to Bi(0), thus leading to more active sites. We also demonstrate that the promoting effect of GDY in CO2 electroreduction can be further extended to other metal catalysts. To the best of our knowledge, such general promoting functions of GDY for CO2 electroreduction have not been documented thus far.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) pandemic has been affecting people's psychosocial health and well-being through various complex pathways. The present study aims to investigate the perceived psychosocial health and its sociodemographic correlates among Chinese community-dwelling residents. METHODS This cross-sectional survey was carried out online and using a structured questionnaire during April 2020. In total, 4788 men and women with the age range of 11-98 years from eight provinces in eastern, central and western China were included in the analysis. We adopted a tactical approach to capture three key domains of perceived psychosocial health that are more likely to occur during a pandemic including hopelessness, loneliness, and depression. Multiple regression method, binary logistic regression model and variance inflation factor (VIF) were used to conduct data analysis. RESULTS Respectively 34.8%, 32.5% and 44.8% of the participants expressed feeling more hopeless, lonely, and depressed during the pandemic. The percentage of all three indicators was comparatively higher among women than among men: hopelessness (50.7% vs 49.3%), loneliness (52.4% vs 47.6%), and depression (56.2% vs 43.8%). Being married was associated with lower odds of loneliness among men (odds ratio [OR] = 0.63, 95% CI: 0.45-0.90). Loneliness was negatively associated with smoking (OR = 0.67, 95% CI: 0.45-0.99) and positively associated with drinking (OR = 1.45, 95% CI: 1.04-2.02). Compared with those in the lowest income bracket (< CNY 10 000), men (OR = 0.34, 95% CI: 0.21-0.55) and women (OR = 0.36, 95% CI: 0.23-0.56) in the highest level of annually housed income (> CNY 40 000) had the lowest odds of reporting perceived hopelessness (OR = 0.35, 95% CI: 0.25-0.48). Smoking also showed negative association with depression only among men (OR = 0.63, 95% CI: 0.43-0.91). CONCLUSIONS More than one-third of the participants reported worsening in the experience of hopelessness and loneliness, with more than two-fifth of worsening depression during the pandemic compared with before the outbreak. Several socioeconomic and lifestyle factors were found to be associated with the outcome variables, most notably participants' marital status, household income, smoking, alcohol drinking, existing chronic conditions. These findings may be of significance to treat patients and help them recover from the pandemic.

Abstract
Arsenic is an environmental poison and is a grade I human carcinogen that can cause many types of damage to the body. The skin is one of the main target organs of arsenic damage, but the molecular mechanisms underlying arsenic poisoning are not clear. Arsenic is an epigenetic agent. Histone acetylation is one of the earliest covalent modifications to be discovered and is closely related to the occurrence and development of tumors. To investigate the role of acetylated histone H3K18 (H3K18 ac) in arsenic-induced DNA damage, HaCaT cells were exposed to sodium arsenite (NaAsO2) for 24 h. It was found that arsenic induced the downregulation of xeroderma pigmentosum A, D, and F (XPA, XPD, and XPF-nucleotide excision repair (NER)-related genes) expression, as well as histone H3K18 ac expression, and aggravated DNA damage. Chromatin immunoprecipitation quantitative polymerase chain reaction (ChIP-qPCR) analysis showed that H3K18 acetylation in the promoter regions of XPA, XPD, and XPF was downregulated. In addition, the use of the histone deacetylase inhibitor trichostatin A (TSA) partially inhibited arsenic-induced DNA damage, inhibited deacetylation of H3K18 ac in the promoter regions of XPA, XPD, and XPF genes, increased acetylation of H3K18, and promoted the transcriptional expression of NER-related genes. Our study revealed that NaAsO2 induces DNA damage and inhibits the expression of NER-related genes, while TSA increases the H3K18 ac enrichment level and promotes the transcriptional expression of NER, thereby inhibiting DNA damage. These findings provide new ideas for understanding the molecular mechanisms underlying arsenic-induced skin damage.

Engineering a CsPbBr3-based nanocomposite for efficient photocatalytic CO2reduction: improved charge separation concomitant with increased activity sites. RSC Adv 2019; 9:34342-34348.

Abstract
Metal-halide perovskite nanocrystals have emerged as one of the promising photocatalysts in the photocatalysis field owing to their low-cost and excellent optoelectronic properties. However, this type of nanocrystals generally displays low activity in photocatalytic CO2 reduction owing to the lack of intrinsic catalytic sites and insufficient charge separation. Herein, we functionalized CsPbBr3 nanocrystals with graphitic carbon nitride, containing titanium-oxide species (TiO-CN) to develop an efficient composite catalyst system for photocatalytic CO2 reduction using water as the electron source. Compared to its congener with pristine CsPbBr3, the introduction of TiO-CN could not only increase the number of active sites, but also led to a swift interfacial charge separation between CsPbBr3 and TiO-CN due to their favorable energy-offsets and strong chemical bonding behaviors, which endowed this composite system with an obviously enhanced photocatalytic activity in the reduction of CO2 to CO with water as the sacrificial reductant. Over 3-fold and 6-fold higher activities than those of pristine CsPbBr3 nanocrystals and TiO-CN nanosheets, respectively, were observed under visible light irradiation. Our study provides an effective strategy for improving the photocatalytic activity of metal-halide perovskite nanocrystals, thus promoting their photocatalytic application in the field of artificial photosynthesis. We have constructed a cost-effective CsPbBr3@TiO-CN composite for photocatalytic CO2 reduction with water as the electron source.![]()

Abstract
The aim of the present study was to measure the prevalence of multimorbidity in Bangladesh, India and China, and to assess the relationship between multimorbidity and patient's opinion regarding their involvement in healthcare decision-making and overall satisfaction of healthcare system. Cross-sectional data on 18 696 men and women aged 18 and above were collected from the World Health Survey of World Health Organization (WHO). Outcome variables were subjective rating of (1) healthcare system's ability to involve patients in decision-making, and (2) satisfaction with the way healthcare system runs in the country. Self-reported chronic conditions were used to measure the prevalence of multimorbidity. Out of 9 chronic conditions, back pain, arthritis, and chronic cough appeared to be the most prevalent ones among majority of the participants. About one-third of the participants in China (30.7%) and two-thirds in Bangladesh (66.1%) and India (66.6%) reported having at least one chronic illness. Prevalence of multimorbidity was highest in India (34.3%) followed by Bangladesh (28.8%) and China (14.3%). In Bangladesh, India and China, respectively 70.5%, 41.7%, 61.3% women and 54.5%, 42.8% and 58.8 % men expressed dissatisfaction regarding the way healthcare system runs in their country. In Bangladesh and India, men who were living with multimorbidity were more likely to rate the patient-centeredness as "bad" than those who had no disease illness. This study suggests that the prevalence of multimorbidity was remarkably high especially in Bangladesh and India. Higher likelihood of dissatisfaction about healthcare system among multimorbid patients might be indicative of inadequacy in the provision of care in qualitative and quantitative terms.

Abstract
Glioma is the most aggressive type of brain tumor. Great progress has been achieved in glioma treatment, but the protein-protein interaction networks underlining glioma are poorly understood. We identified the protein-protein interaction network for glioma based on gene expression and predicted biological pathways underlying the molecular complexes in the network. Genes involved in glioma were selected from the Online Mendelian Inheritance in Man (OMIM) database. A literature search was performed using the Agilent Literature Search plugin, and Cytoscape was used to establish a protein-protein interaction network. The molecular complexes in the network were detected using the Clusterviz plugin, and pathway enrichment of molecular complexes was performed using DAVID online. There were 378 glioma genes in the OMIM database. The protein-protein interaction network in glioma contained 1814 nodes, 6471 edges, and 8 molecular complexes. There were 17 pathways (false discovery rate <1), which were related to cytokine-cytokine receptor interaction, Toll-like receptor signaling pathway, chemokine signaling pathway, oocyte meiosis, progesterone-mediated oocyte maturation, transmembrane transport of small molecules, metabolism of amino acids, and notch signaling pathway, among others. Our results provide a bioinformatic foundation for further studies of the mechanisms of glioma.

Abstract
The current situation of medical staff's awareness about high alert medication was investigated in order to promote safe medication and standardized management of the high alert medication in China. Twenty questions were designed concerning elementary knowledge of high alert medications, storage management, medication issues and risks. In order to understand the knowledge level and education status of high alert medication, a convenient survey was conducted among 300 medical staffs in Tianjin. Medical staff's average score of high alert medication knowledge was 12.43±0.27, and the average scores of elementary knowledge of high alert medication, storage management, medication issues and risks were 3.38±0.11, 2.46±0.14, 3.17±0.11 and 3.41±0.12 respectively. Occupation (F=4.86, P=0.003), education background (F=5.57, P=0.019) and professional titles (F=13.44, P≤0.001) contributed to the high alert medications knowledge scores. Currently, the most important channel to obtain high alert medication knowledge was hospital files or administrative rules, and clinical pharmacist seminars were the most popular education form. It was suggested that the high alert medication knowledge level of the medical staff needs to increase, and it might benefit from targeted, systematic and diverse training to the medical staff working in the different circulation nodes of the medications. Further research to develop and validate the instrument is needed.

Abstract
PURPOSES To investigate the responses of the craniovertebral (CV) angle to backpack loadings in adolescents with and without neck pain and to explore the relationships between CV angle, relative backpack weight, neck pain and disability. METHODS A cross-sectional single-blinded study was conducted on 60 adolescents (30 neck pain and 30 non-neck pain) aged from 13 to 18 years old. The verbal analog scale (VAS) and Chinese version of Northwick Park Neck Pain Questionnaire (NPQ) were used to assess neck pain severity and disability respectively. CV angle was measured in neutral and with backpack loadings of 5% to 30% of subject's body weight by using the Head Posture Spinal Curvature Instrument (HPSCI). RESULTS In both groups, CV angles gradually decreased with increment of backpack loadings and the amount of decreases became significant from 10% body weight onwards (P < 0.05). Although the changes of CV angles did not show any significant differences at any point of comparison between the groups, the neck pain group showed a clinically significant decrease of CV angle (∼ 5°) at 10% relative loading whereas non-neck pain group did it at 15% relative loading. Change of CV angles did not show significant correlations with relative backpack weight, cervical pain and disability (P > 0.05). CONCLUSIONS Our findings suggested a safety limit of 10% relative backpack load for adolescents. The results showed the tendency that the ability of maintaining good head posture in response to backpack loadings by non-neck pain subjects might be better than those with neck pain.

Abstract
INTRODUCTION A study was carried out in a primary healthcare clinic in the Hulu Langat district of Malaysia to assess the parental knowledge, attitudes and antibiotic use for common childhood acute upper respiratory tract infection (URTI). METHODS A cross-sectional study involving 421 parents, who were surveyed by using an interviewer-administered questionnaire, from April to June 2001. RESULTS Approximately 59 percent of parents from this study believed that weather was the main cause of acute URTI of their children, 13 percent thought it was due to food, and only about 27 percent said it was caused by germs. Nearly 68 percent, 69 percent and 76 percent of them believed that antibiotics was helpful in treating the common cold, cough and fever, respectively. 29 percent of parents who thought that their child with acute URTI needed antibiotics were not prescribed with any. On the other hand, 17 percent believed that antibiotics were unnecessary when prescribed. 28 percent of parents had requested for antibiotics, and 93 percent received what they requested for their child with acute URTI. About 31 percent of parents who did not request any antibiotics claimed that private general practitioners habitually prescribed antibiotics. The antibiotic compliance was poor with only 74 percent completing the entire course, with 85 percent of them stopping once they improved symptomatically. 15 percent of parents gave "leftover" antibiotics, 24 percent gave "shared" antibiotics, and 5.5 percent bought antibiotics for their child with acute URTI without consulting a doctor. CONCLUSION This study shows that parents often have inadequate knowledge and misconceptions on antibiotic use for acute URTI in children. Improved parental education may reduce unnecessary antibiotic prescription and antimicrobial resistance in the community.

Abstract
OBJECTIVES To evaluate the electromyographic activities of vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles in open and closed kinetic chain exercises in subjects with patellofemoral pain syndrome (PFPS). DESIGN Case-controlled study. SETTING Rehabilitation science center in a tertiary medical center. PARTICIPANTS Ten patients with bilateral knee pain diagnosed with PFPS and 10 healthy volunteers. INTERVENTIONS Subjects performed open kinetic chain exercise on an isokinetic dynamometer and closed kinetic chain exercise by squat-to-stand and stand-to-squat tasks. Surface electromyography was done for the VMO and VL muscles. MAIN OUTCOME MEASURES VMO/VL ratios were calculated after normalization of muscle activities. RESULTS The VMO/VL ratios of PFPS subjects were significantly lower than were those of unimpaired subjects during knee isokinetic closed kinetic chain exercises (p = .047). However, there was no statistical difference in VMO/VL ratio between subjects with and without PFPS during closed kinetic chain exercises (p = .623). Maximum VMO/VL ratio was obtained at 60 degrees knee flexion in closed kinetic chain exercise. CONCLUSION In closed kinetic chain exercises, more selective VMO activation can be obtained at 60 degrees knee flexion. Maximal VMO/VL ratio was observed at this knee flexion angle, and muscle contraction intensity was also greatest.

Abstract
UNLABELLED Inhaled nitric oxide is a potent vasodilator in acute severe pulmonary hypertension and is increasingly used as rescue treatment in intensive care algorithms aiming at reducing severe hypoxaemia in neonates and children. Although the immediate effects may seem impressive, long-term outcome regarding residual pulmonary hypertension and other sequelae has been studied in only a very few patients. The aim of the present study was to evaluate residual pulmonary hypertension, cardiopulmonary or neurological symptoms in children after treatment with inhaled nitric oxide in severely hypoxaemic and/or pulmonary hypertensive mechanically ventilated children. The study was performed in four paediatric intensive care units in university hospitals in Sweden, Norway and Australia. Patients who had received inhaled nitric oxide as part of their intensive care treatment for severe hypoxaemia and/or pulmonary hypertension, and in whom 6 mo had elapsed since treatment, were included for evaluation. Thus 36 paediatric or neonatal patients were examined for circulatory, respiratory or neurological disorders with clinical examination, echocardiography, chest X-ray and a capillary blood sample. Four patients with congenital heart disease had residual pulmonary hypertension. Nine patients were receiving bronchodilators. Sixteen patients had minor (n = 15) or moderate (n = 1) changes on a chest X-ray. One patient had a possible delay in psychomotor development. CONCLUSIONS In spite of the severity of their primary illness, we found that the overwhelming majority of the surviving children were asymptomatic and doing well. The few residual circulatory and respiratory symptoms could be related to the initial condition.

Abstract
BACKGROUND Pulmonary hypertensive crises (PHTC) are a major cause of morbidity and mortality after congenital heart surgery. Inhaled nitric oxide is frequently used as rescue therapy. We did a randomised double-blind study to investigate the role of routinely administered inhaled nitric oxide to prevent pulmonary hypertension in infants at high risk. METHODS We enrolled 124 infants (64 male, 60 female; median age 3 months [IQR 1-5]), 76% with large ventricular or atrioventricular septal defects, who had high pulmonary flow, pressure, or both, and were undergoing corrective surgery for congenital heart disease. They were randomly assigned continuous low-dose inhaled nitric oxide (n=63) or placebo (n=61) from surgery until just before extubation. We measured the numbers of PHTC, time on study gas, and hours spent in intensive care. Analysis was done by intention to treat. FINDINGS Compared with placebo, infants receiving inhaled nitric oxide had fewer PHTC (median four [IQR 0-12] vs seven [1-19]; relative risk, unadjusted 0.66, p<0.001, adjusted for dispersion 0.65, p=0.045) and shorter times until criteria for extubation were met (80 [38-121] vs 112 h [63-164], p=0.019). Time taken to wean infants off study gas was 35% longer in the nitric oxide group than in the placebo group (p=0.19), but the total time on the study gas was still 30 h shorter for the nitric oxide group (87 [43-125] vs 117 h [67-168], p=0.023). No important toxic effects arose. INTERPRETATION In infants at high risk of pulmonary hypertension, routine use of inhaled nitric oxide after congenital heart surgery can lessen the risk of pulmonary hypertensive crises and shorten the postoperative course, with no toxic effects.

Abstract
BACKGROUND Inhaled nitric oxide (iNO) is a potential therapeutic agent for the management of acute respiratory distress syndrome (ARDS). Concerns remain, however, regarding the potential toxicity from iNO and/or its oxidative derivatives and methaemoglobinaemia. AIMS To determine the risk of toxicity from iNO, which includes worsening of lung injury, a prospective study evaluating the acute effects of three concentrations of iNO on gas exchange and haemodynamics in 12 children with ARDS was performed in a tertiary paediatric intensive care unit. INTERVENTION iNO was administered for one hour at three concentrations (1, 10, and 20 parts per million (ppm)) in a random order of possible dosing schedules to avoid dose accumulation bias. Arterial blood gas, methaemoglobin concentrations, and haemodynamic parameters were obtained at baseline before commencement of iNO, at the end of each study hour, and after iNO was discontinued. Nitric oxide and nitrogen dioxide concentrations were continuously monitored during the study. RESULTS iNO significantly improved the oxygenation ratio (Pao2/Fio2) from a mean (SEM) baseline of 11.9 (1.7) kPa to 20 (3.9) kPa, 24 (4.5) kPa, and 21.6 (3.9) kPa at 1, 10, and 20 ppm iNO, respectively. There was no significant difference in the improvement in oxygenation achieved between the three concentrations. Correspondingly, there was a significant improvement in oxygenation index (pre-iNO 28.3 (5) v post-iNO 18 (3) (1 ppm), 15 (3) (10 ppm), 16 (3) (20 ppm)). No toxicity from methaemoglobinaemia or nitrogen dioxide was seen during iNO administration. CONCLUSION The results show that a low concentration of iNO (1 ppm) is as effective as higher concentrations (10 and 20 ppm) in improving oxygenation in children with ARDS and may be important in minimising toxicity during iNO use.

Abstract
OBJECTIVE To assess the respective roles of general pediatricians and pediatric subspecialists in the provision of primary pediatric care. DESIGN AND METHODS A practice characteristics questionnaire that included questions about primary care was sent to a random sample of 1616 board-certified and board-eligible active Fellows of the American Academy of Pediatrics; 1145 (70.9%) responded. Analyses pertain to those pediatricians who provided ambulatory patient care and were not in graduate medical education training at the time of the survey. Respondents were divided into 2 groups for purposes of analysis: the 527 pediatricians whose practice was primarily in general pediatrics (defined as 80% of time spent in general pediatrics or any time spent in adolescent medicine) and the 213 pediatricians whose practice was subspecialty focused (all others). These groups were then further stratified according to whether they provided primary care. The resultant subgroups contained 518 general pediatricians and 98 subspecialists who provided primary care. RESULTS Among the entire sample, general pediatricians indicated that general pediatricians provide 93% of the primary care delivered by their practice and that pediatric subspecialists provide 2% of the primary care. In contrast, pediatric subspecialists reported that general pediatricians provide 53% of the primary care delivered by their practice and that subspecialists provide 32% of such care (P<.001). Among the subsample of pediatricians who provide primary care, general pediatricians reported delivering 88% of the primary care received by their patients and subspecialists reported delivering 74% of the primary care received by their patients (P<.001). CONCLUSION Perspectives on the degree to which pediatric subspecialists provide primary pediatric care vary depending on generalist vs subspecialist self-identification.

Abstract
BACKGROUND In order to reduce the work load of nursing staff who provide long term care to the patients who are in a persistent vegetative state (PPVS), a centralized open care system which can accommodate 140 PPVS was developed. This system contained a multifunctional bed, auto-bathing machine transported by an automatically guided vehicle, a dental cleansing device, remote excreta detection diaper, and a centralized feeding system. METHOD The multifunctional bed consisted of a modified bed top with automatically controlled moving bars covered by plastic foam to reduce pressure on the back. The inclination of the bed could be adjusted automatically. The patient could be transferred to an auto-bathing shower machine using a robotic arm mounted on the unmanned cart (TRANSCAR). RESULTS The clothing of the PPVS was modified to a single piece with Velcro closures. A T-shaped diaper contained a sensor and alarm for indicating the presence of excreta. Patients' temperatures were monitored by infrared aural thermometry. An automatic jet-spray and suction device for dental cleansing was also designed. Feeding was delivered by an automatic feeder attached to a minirefrigerating device with a patient centralized control system. The results showed that the system reduced the total nursing hours of each PPVS from 4.60 to 1.83 hours/day. CONCLUSION A clinical trial of this system with 3 healthy young adults and 3 PPVS was conducted. Many parts of the system need improvement, in order to prevent the slipping of a toe or finger into the moving bars of the bed, keep the whole body clean, and increase the sensitivity of excreta detection.

Abstract
OBJECTIVE To inform policymakers and child health advocates about children's health insurance coverage in each state as Congress debates proposals to restructure the Medicaid program amidst declining employer-based dependent health insurance coverage. METHODS Multiple years of data from the March supplement of the Current Population Surveys were pooled to yield more reliable estimates of changes in children's health insurance coverage in each state from 1987 to 1993. RESULTS Overall, the number of uninsured children grew by nearly 1 million between 1987 and 1993. The proportion of infants and children <7 years old without health insurance declined; the proportion of uninsured children between the ages of 7 and 22 increased. Between 1987-1990 and 1991-1993, six states experienced a significant increase in the number of uninsured children, only two states experienced a significant decrease in the number of uninsured children, although no progress was found in reducing the number of uninsured children in 43 states. Between 1987-1990 and 1991-1993, the proportion of children covered by employer-based private insurance decreased significantly in three-fourths of the states and the proportion of children with Medicaid coverage increased significantly in four-fifths of the states. CONCLUSIONS In a period of fast-declining employer-based health insurance coverage for dependents, Medicaid expansions have worked to moderate the surge in the number of children without health insurance. Of the 30 million children without private health insurance in 1993, nearly 18 million were insured by Medicaid. As policymakers debate the future of the Medicaid program, they must consider seriously its role as the country's largest insurer of children's health and its efficacy as a vital safety net for the nation's children.

Abstract
Inhaled nitric oxide is currently being investigated as a selective pulmonary vasodilator for neonates with persistent pulmonary hypertension. The use of continuous inhaled nitric oxide during emergency transportation of three critically III neonates with meconium aspiration and pulmonary hypertension is described. The successful application of this technique may allow safer transportation of neonates who require high level intensive care including ongoing nitric oxide, high frequency ventilation and/or extracorporeal life support. Regionally based nitric oxide-equipped retrieval teams may relieve the pressure on smaller neonatal intensive care units to provide inhaled nitric oxide therapy and allow centralization of nitric oxide resources, thus facilitating development of expertise and the completion of meaningful research programs with substantial recruitment.

Abstract
OBJECTIVE Inhaled nitric oxide (iNO) has been shown to cause selective pulmonary vasodilatation and improve ventilation-perfusion matching and may be an important therapeutic option for the treatment of persistent pulmonary hypertension of the newborn (PPHN). We report our experience on the use of iNO in neonates with severe PPHN. METHODOLOGY Inhaled NO was administered to 10 infants with PPHN and persistent hypoxaemia (meconium aspiration syndrome, n = 9; pneumonia, n = 1) after failure of conventional therapy to improve oxygenation. With the exception of one infant, iNO was commenced at 10 ppm. RESULTS After 30 min exposure to iNO, the arterial oxygen tension (PaO2) rose from a median of 49 mmHg (6.5 kPa) [range 12-82 mmHg (1.6-10.9 kPa)] to 75 mmHg (10 kPa) [range 17-450 mmHg (2.3-60 kPa)] (P = 0.005), while the median oxygenation index fell (pre-iNO of 37 vs post-iNO 20) (P = 0.005) and median systemic arterial pressure rose (pre-iNO 46.5 mmHg (6.2 kPa) [range 32-63 mmHg (4.3 to 8.4 kPa vs post-iNO 54.5 mmHg (7.3 kPa) [range 36-74 kPa]) P = 0.005). All infants subsequently continued to receive iNO with the duration of exposure to iNO ranging from 12 to 168 h (median duration 100 h). Three infants died despite showing an initial beneficial response to iNO. The mean duration of intubation for survivors was 11.9 +/- 2.6 days. Methaemoglobinaemia and toxic levels of nitrogen dioxide were not seen during iNO administration. Of the seven survivors, 12 month follow up in two infants and 4 month follow up in four infants showed age-appropriate neurodevelopmental skills, with one infant having very mild hearing loss. CONCLUSIONS Inhaled NO reduces the oxygenation index by improving the PaO2 and decreasing ventilation pressures, and appears to be clinically useful in severely hypoxaemic infants with PPHN refractory to conventional treatment.

Abstract
Our experience with intracavernous injection of prostaglandin E1 in spinal cord injured patients with neurogenic erectile dysfunction included 15 men. They received testing dosage starting from 5 micrograms with increasing dosage (maximum 20 micrograms) to achieve a rigid erection of Schramek's grade 5 and lasting for at least 20 min. All of them had achieved functional erection adequate for coitus after treatment except one patient who had been proved to have venogenic impotence. We found that intracavernous injection of prostaglandin E1 had significantly improved the erectile condition. No systemic side effect or any other complication was noted except that pain at the injection site was complained of in two patients with incomplete lesion.

Abstract
Neurocontrol of movement after spinal cord injury (SCI) is often spared, but few studies have investigated the chronic incomplete SCI patient. Multichannel surface electromyography (SEMG) can describe characteristics of neurocontrol during a series of volitional and reflex events. The relationship of these neurocontrol characteristics to clinical function is incompletely described. This study, retrospectively, evaluated the relationship between neurocontrol patterns evoked by lower limb movement in the supine position and the assistive device used for ambulation in chronic, incomplete SCI persons. The records of 15 neurologically healthy (9 male, 6 female) and 36 incomplete SCI persons (27 male, 9 female) (C2-T10) were used. SEMG was recorded from both quadriceps, adductors, hamstrings, anterior tibialis and triceps surae muscles and displayed on a stripchart for analysis. SEMG patterns of activity recorded in the supine position during volitional, unilateral, multijoint (hip and knee flexion and extension) movement attempts were characterized, divided into seven groups and compared with the subjects' self-selected ambulation device (independent, cane, crutches, walker or nonambulatory). The neurocontrol patterns recorded in the supine position correlated well with the SCI subjects ambulatory assistive device. Marked decreases in motor unit output and/or loss of motor organization were found in the nonambulatory group. Coactivation of proximal muscles, poor timing of muscle activity and radiation of activity into contralateral muscles were also noted in subjects who required a walker or crutches. To a lesser degree, abnormal motor patterns were also noted in subjects who ambulated with a cane or independently.

Abstract
A 10-year-old girl presented with progressive dystonia with diurnal fluctuation. Response to low dose L-Dopa was dramatic and sustained with no complications. Recurrence of symptoms was observed on attempted withdrawal. Because of the dramatic response to therapy, dopa-responsive dystonia must be considered in the differential diagnosis of disorders presenting as gait disorders in childhood.

Abstract
Mixed longitudinal data of length and weight growth from 595 rural and 337 urban infants were analysed. Count models were fitted to the means of length and weight in different ages, sexes and feedings separately. The curve fitting to the data was rather satisfactory. Comparison of model parameters between urban and rural infants suggested that rural infants had a higher length level at birth but lower accelerative growth afterwards than urban ones, which was even more obvious in breast-fed infants. The difference in birth weight between them was not significant; and the urban infants had a faster linear growth velocity than rural ones. These results might be caused by the fact that food supplementing in urban infants was significantly earlier and better than in rural ones.
