RESUMEN
PURPOSE: Pediatric diffuse malignant glioma located in the brainstem was officially named "diffuse midline glioma" (DMG) by the World Health Organization in 2016. For this disease, radical surgery is not beneficial, and the only major treatment strategy is radiotherapy. However, the dose limitations to brainstem tissue mean that treatment by radiotherapy can only control and not eradicate the tumors, and there is no effective treatment for recurrence, resulting in short overall survival of 6-12 months. This paper reports our experience with boron neutron capture therapy (BNCT), a new treatment process, and its efficacy in treating children with recurrent DMG. METHODS: From September 2019 to July 2022, we treated 6 children affected by recurrent DMG. With the collaboration of Taipei Veteran General Hospital (TVGH) and National Tsing-Hua University (NTHU), each patient received two sessions of BNCT within 1 month. RESULTS: Among the six patients, three showed partial response and the rest had stable disease after the treatment. The overall survival and recurrence-free survival duration after treatment were 6.39 and 4.35 months, respectively. None of the patients developed severe side effects, and only one patient developed brain necrosis, which was most likely resulted from previous hypofractionated radiotherapy received. CONCLUSION: BNCT elicited sufficient tumor response with low normal tissue toxicity; it may benefit vulnerable pediatric patients with DMG.

OBJECTIVE: The purpose of this meta-analysis is to assess the effect of dexmedetomidine on delirium in elderly surgical patients. DATA SOURCES: The Cochrane Library, Web of Science, PubMed, EMBASE, and Google Scholar were searched (January 1, 2000, to February 4, 2020) for randomized controlled trials (RCTs). STUDY SELECTION AND DATA EXTRACTION: RCTs without language restrictions were included if delirium incidence was assessed in elderly surgical patients receiving dexmedetomidine. Intervention and basic information were extracted. DATA SYNTHESIS: 21 studies were included. Dexmedetomidine reduced delirium occurrence (risk ratio [RR] = 0.55; 95% CI = 0.45 to 0.67) in elderly surgical patients with sufficient evidence from trial sequential analysis. Dexmedetomidine did not prevent delirium incidence for cardiac surgery (RR = 0.71; 95% CI = 0.44 to 1.15) with insufficient evidence. Dexmedetomidine decreased mortality incidence (RR = 0.47; 95% CI = 0.25 to 0.89), shortened the length of intensive care unit (ICU; standard mean difference [SMD] = -0.46) and hospital stays (SMD = -0.41), and increased bradycardia incidence (RR = 1.60). RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: This review revealed that dexmedetomidine could reduce delirium incidence for elderly noncardiac surgical patients, and the effect of dexmedetomidine on delirium for elderly cardiac surgical patients needs further studies to guide clinicians. CONCLUSION: Dexmedetomidine reduced delirium incidence in elderly surgical patients. The efficacy of dexmedetomidine on delirium for elderly cardiac surgical patients warrants further studies. Furthermore, dexmedetomidine was associated with an increased bradycardia incidence, shorter length of ICU/hospital stays, and a lower incidence of mortality.

BACKGROUND: Primary carnitine deficiency (PCD) is an autosomal recessive disorder affecting the carnitine cycle and resulting in defective fatty acid oxidation. Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disorder and one of the main causes of inherited neonatal cholestasis. Both PCD and NICCD are included in the current expanded newborn screening (NBS) targets. CASE PRESENTATION: Targeted exome sequencing was performed on a Chinese proband, and Sanger sequencing was utilised to validate the detected mutations. The patient who was initially suspected to have PCD based on the NBS results presented with neonatal intrahepatic cholestasis and ventricular septal defect. Further investigations not only confirmed PCD but also revealed the presence of NICCD. Four distinct mutations were detected, including c.51C > G (p.F17L) and c.760C > T (p.R254X) in SLC22A5 as well as c.615 + 5G > A and IVS16ins3kb in SLC25A13. CONCLUSIONS: This is the first reported case of PCD and NICCD occurring in the same patient. The dual disorders in a newborn broaden our understanding of inherited metabolic diseases. Thus, this study highlighted the importance of further genetic testing in patients presenting with unusual metabolic screening findings.

OBJECTIVE: To summarize newborn screening for methionine adenosyltransferase I/III (MAT I/III) deficiency in Quanzhou region of Fujian Province. METHODS: A total of 364 545 neonates were screened for inherited metabolic diseases by tandem mass spectrometry. High-throughput next generation sequencing combined with Sanger sequencing was used to detect potential variants in newborns with MAT I/III deficiency. Pathogenicity of suspected variants was predicted by using MutationTaster and HSF software. RESULTS: Three newborns were identified with MAT I/III deficiency by newborn screening, which yielded an incidence rate of 1 in 121 515. Amino acid and acylcarnitine analysis suggested that the serum methionine of the three patients have increased to various extents. All patients showed normal growth and development during follow-up, and were found to carry MAT1A gene variants including two missense variants [c.776C>T (p.Ala259Val) and c.791G>A (p.Arg264His)] and a synonymous variant [c.360C>T (p.Cys120Cys)]. Among these, c.776C>T (p.Ala259Val) and c.791G>A (p.Arg264His) were known to be pathogenic, whereas c.360C>T (p.Cys120Cys) was a novel variant. Bioinformatics analysis suggested that this variant may alter RNA splicing and affect the structure and function of the MAT1A protein. CONCLUSION: A systematic review of newborn screening for MAT I/III deficiency was provided. Discovery of the novel variant has enriched the variant profile of the MAT1A gene and provided a basis for the diagnosis of this disease.

BACKGROUND: Methylmalonic acidemia (MMA) is an autosomal recessive inherited disorder caused by complete or partial deficiency of the enzyme methylmalonyl-CoA mutase (mut0 enzymatic subtype or mut- enzymatic subtype, respectively); a defect in the transport or synthesis of its cofactor, adenosyl-cobalamin (cblA, cblB, or cblD-MMA); or deficiency of the enzyme methylmalonyl-CoA epimerase. The cblA type of MMA is very rare in China. This study aimed to describe the biochemical, clinical, and genetic characteristics of two siblings in a Chinese family, suspected of having the cblA-type of MMA. METHODS: The Chinese family of Han ethnicity of two siblings with the cblA-type of MMA, was enrolled. Target-exome sequencing was performed for a panel of MMA-related genes to detect causative mutations. The influence of an identified missense variant on the protein's structure and function was analysed using SIFT, PolyPhen-2, PROVEAN, and MutationTaster software. Moreover, homology modelling of the human wild-type and mutant proteins was performed using SWISSMODEL to evaluate the variant. RESULTS: The proband was identified via newborn screening (NBS); whereas, her elder brother, who had not undergone expanded NBS, was diagnosed later through genetic family screening. The younger sibling exhibited abnormal biochemical manifestations, and the clinical performance was relatively good after treatment, while the older brother had a mild biochemical and clinical phenotype, mainly featuring poor academic performance. A novel, homozygous missense c.365T>C variant in exon 2 of their MMAA genes was identified using next-generation sequencing and validated by Sanger sequencing. Several different types of bioinformatics software predicted that the novel variant c.365T>C (p.L122P) was deleterious. Furthermore, three-dimensional crystal structure analysis revealed that replacement of Leu122 with Pro122 led to the loss of two intramolecular hydrogen bonds between the residue at position 122 and Leu188 and Ala119, resulting in instability of the MMAA protein structure. CONCLUSIONS: The two siblings suspected of having the cblA-type of MMA showed mild phenotypes during follow-up, and a novel, homozygous missense variant in their MMAA genes was identified. We believe that the clinical features of the two siblings were associated with the MMAA c.365T>C variant; however, further functional studies are warranted to confirm the variant's pathogenicity.

OBJECTIVE: To investigate the significance of monitoring procalcitonin (PCT) when applying antibiotics to trichlorethylene (TCE)-induced dermatitis. METHODS: One hundred and two patients who were hospitalized and recovered from TCE-induced dermatitis in our hospital from 2006 to 2013 were enrolled as subjects. Based on whether the PCT level was monitored or not, we divided patients into regular group and PCT group. For the regular group, we applied antibiotic treatment and determined the course of treatment based on clinical symptoms, laboratory test results, medical imaging results, and bacterial culture. For the PCT group, in addition to the above treatments, antibiotic treatment was applied when the PCT level was not lower than 0.25 ng/ml and stopped when the PCT level was lower than 0.25 ng/ml. The distribution of bacterial infection sites, type of bacteria, type of antibiotics, average period of hospitalization, and course of antibiotic treatment were compared between the two groups. RESULTS: There were no significant differences in the distribution of bacterial infection sites, type of bacteria, type of antibiotics, and average period of hospitalization between the two groups (P > 0.05). The course of antibiotic treatment for the PCT group was significantly shorter than that for the regular group (25.37 ± 11.66 vs 20.58 ± 7.53 d, P < 0.05). CONCLUSION: Under similar conditions of bacterial infection, antibiotic treatment of TCE-induced dermatitis based on the serum PCT level can significantly shorten the course of treatment and avoid the abuse of antibiotics.

BACKGROUND: Glucohexaose is a safe farm chemical used for pathogen prevention, which can induce systemic acquired resistance in cucumber. RESULTS: We found that glucohexaose treatment of cucumber plant induced an accumulation of the reactive oxidative species (ROS). Histochemistry showed sharp increases in O(2-) and H2O2 5 h after glucohexaose treatment. After 5 h, the O(2-) content decreased to a normal level, but the H2O2 content remained at a high level 10 h after glucohexaose treatment. And antioxidant enzymes were also changed after glucohexaose treatment. We also investigated the relationship between ROS accumulation and glucohexaose-induced proteome alteration using 2D electrophoresis coupled with MS/MS. 54 protein spots, which enhanced expression under glucohexaose treatment but suppressed the expression by application of DPI and DMTU, have been identified. CONCLUSION: Our study showed the accumulation of ROS is a part of mechanism of glucohexaose induced resistance in cucumber cotyledons. The up-regulated proteins identified by MS such as PP2C and antioxidation proteins are important in ROS signaling. It will be interesting to find out the regulatory mechanism underlying the induction of these proteins via ROS, and provide some clues to the mechanism of glucohexaose-induced resistance.
RESUMEN
BACKGROUND: Since the increasing smoking rate among women has resulted in higher rates of embryonic malformations, it is important to search for an efficient and inexpensive agent that can help reduce the rate of serious fetal anomalies caused by maternal cigarette smoking. In this study, the bioavailability of 4-O-methylhonokiol isolated from Magnolia officinalis was first demonstrated in the mouse embryos exposed to nicotine using a whole embryo culture system. METHODS: Mouse embryos on embryonic day 8.5 were cultured with 1 mM nicotine and/or 4-O-methylhonokiol (1 × 10(-4) or 1 × 10(-3) µM) for 48 hr and were analyzed on the viewpoints of embryo developmental changes, oxidative damages, and apoptotic and inflammatory changes. RESULTS: Embryos exposed to 1 mM nicotine developed not only severe morphological anomalies, increased expressions of tumor necrosis factor-α, interleukin-1ß, and caspase 3 mRNAs; and elevated levels of lipid peroxidation, but also decreased levels of cytoplasmic superoxide dismutase, cytosolic glutathione peroxidase, phospholipid hydroperoxide glutathione peroxidase, hypoxia inducible factor-1α, and B-cell lymphoma-extra large mRNAs, and reduced superoxide dismutase activity. However, these parameters were significantly improved when embryos exposed to the nicotine were concurrently treated with 4-O-methylhonokiol (1 × 10(-4) or 1 × 10(-3) µM). CONCLUSIONS: These findings indicate that 4-O-methylhonokiol reduces serious embryo anomalies caused by nicotine in mouse embryos via the modulations of oxidative stress, apoptosis, and inflammation, suggesting that 4-O-methylhonokiol may be a preventive and therapeutic agent against the dysmorphology induced by maternal smoking during pregnancy.

OBJECTIVE: To explore the effect of Shugan Jianpi Recipe (SJR) on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in nonalcoholic fatty liver disease (NAFLD) rats. METHODS: Totally 75 SPF grade male SD rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shugan Recipe (SR) treatment groups, the Jianpi Recipe (JR) treatment group, and the SJR group. Except rats in the normal control group, the NAFLD rat model was duplicated using high fat diet (HFD). SR (Chaihu Shugan Powder) was administered to rats in the SR group. JR (Shenlin Baizhu Powder) was administered to rats in the JR group. SJR (Chaihu Shugan Powder plus Shenlin Baizhu Powder) was administered to rats in the SJR group. Changes of liver fat were analyzed using automatic biochemical analyzer. Liver cells were separated by low-speed centrifugation. Their activities and purities were identify using Typan blue and flow cytometry (FCM). Expression levels of LXRα and FAS mRNA in hepatocytes detected by Real-time quantitative PCR. Expression levels of LXRα and FAS protein were detected by Western blot. RESULTS: (1) Pathological results showed in the model group, hepatocytes were swollen with nucleus locating at the cell edge after oil red O staining; unequal sized small vacuoles could be seen inside cytoplasm. Some small vacuoles merged big vacuoles. All these indi- cated a NAFLD rat model was successfully established by high fat diet. Pathological structural changes could be impaired to some degree in all medicated groups, especially in the SR group. (2) Compared with the normal control group, expression levels of LXRα and FAS genes and proteins obviously increased in the model group (P < 0.01). Compared with the model group, their expression levels were obviously down-regulated in the JR group and the SR group (P < 0.01, P < 0.05). CONCLUSIONS: LXRα/FAS signaling pathway was an important signaling pathway for mediating lipid metabolism disorders of NAFLD rats. SJR could make hepatocyte fatty deposits tend to repair by adjusting the LXRα/FAS signaling pathway in NAFLD rats, which might be one of important mechanisms for SJR to prevent and cure NAFLD.

OBJECTIVE: To explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway. METHOD: The hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot. RESULT: The rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group. CONCLUSION: The soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

OBJECTIVES: Newborn screening (NBS) for primary carnitine deficiency (PCD) exhibits suboptimal performance. This study proposes a strategy to enhance the efficacy of second-tier genetic screening by adjusting the cutoff value for free carnitine (C0). METHODS: Between January 2021 and December 2022, we screened 119,898 neonates for inborn metabolic disorders. Neonates with C0 levels below 12⯵mol/L were randomly selected for second-tier genetic screening, employing a novel matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) assay. RESULTS: In total, 2,515 neonates with C0 <12⯵mol/L underwent further screening, including 206 neonates with C0 <8.5⯵mol/L and 320 neonates with 8.5

RESUMEN
Background and aims: Fatty acid oxidation disorders (FAODs) are a group of autosomal recessive metabolic diseases included in many newborn screening (NBS) programs, but the incidence and disease spectrum vary widely between ethnic groups. We aimed to elucidate the incidence, disease spectrum, and genetic features of FAODs in a southern Chinese population. Materials and methods: The FAODs screening results of 643,606 newborns from 2014 to 2022 were analyzed. Results: Ninety-two patients were eventually diagnosed with FAODs, of which 61 were PCD, 20 were MADD, 5 were SCADD, 4 were VLCADD, and 2 were CPT-IAD. The overall incidence of FAODs was 1:6996 (95 % CI: 1:5814-1:8772) newborns. All PCD patients had low C0 levels during NBS, while nine patients (14.8 %) had normal C0 levels during the recall review. All but one MADD patients had elevated C8, C10, and C12 levels during NBS, while eight patients (40 %) had normal acylcarnitine levels during the recall review. The most frequent SLC22A5 variant was c.760C > T (p.R254*) with an allele frequency of 29.51 %, followed by c.51C > G (p.F17L) (17.21 %) and c.1400C > G (p.S467C) (16.39 %). The most frequent ETFDH variant was c.250G > A (p.A84T) with an allelic frequency of 47.5 %, followed by c.524G > A (R175H) (12.5 %), c.998A > G (p.Y333C) (12.5 %), and c.1657T > C (p.Y553H) (7.5 %). Conclusion: The prevalence, disease spectrum, and genetic characteristics of FAODs in a southern Chinese population were clarified. PCD was the most common FAOD, followed by MADD. Hotspot variants were found in SLC22A5 and ETFDH genes, while the remaining FAODs showed great molecular heterogeneity. Incorporating second-tier genetic screening is critical for FAODs.
RESUMEN
BACKGROUND: Maternal alcohol ingestion on pregnant period causes fetal alcohol syndrome including psychological and behavioral problems, and developmental abnormality. In this study, we investigated the effect of emodin, an active anthraquinone component found in the roots and bark of the genus Rhamnus (Buckthorn), on ethanol-induced teratogenesis during embryonic organogenesis. METHODS: We cultured mouse embryos on embryonic day 8.5 for 2 days with ethanol (5 µl/3 ml) and/or emodin (1×10(-5) and 1×10(-4) µg/ml) using a whole embryo culture system and then investigated the developmental evaluation, superoxide dismutase (SOD) activity, and expression patterns of cytoplasmic SOD (SOD1), mitochondrial SOD (SOD2), cytosolic glutathione peroxidase (cGPx), tumor necrosis factor-α (TNF-α), caspase 3, and hypoxia inducible factor 1α (HIF-1α). RESULTS: Morphological parameters, including growth in yolk sac and fetal head, body length, and development of the central nervous system, circulation system, sensory organs, skeletal system, and limbs in embryos exposed to ethanol were significantly decreased compared to those of the normal control group, but co-treatment with emodin (1 × 10(-5) and 1 × 10(-4) µg/ml) significantly improved these parameters. Furthermore, the reduced levels of SOD activity, and SOD1, SOD2, cGPx, and HIF-1α and the increased gene levels of TNF-α and caspase-3 due to ethanol exposure were significantly restored by cotreatment with emodin. Birth Defects Res (Part B) 98:268-275, 2013. © 2013 Wiley Periodicals, Inc. CONCLUSIONS: This study revealed that cotreatment with emodin significantly prevented teratogenesis induced by ethanol, not only by modulating hypoxia and antioxidant enzymes, but also by attenuating the enhanced levels of TNF-α and caspase 3 in cultured embryos. Therefore, emodin may be an effective preventive agent for ethanol-induced teratogenesis.

BACKGROUND/PURPOSE: The outcomes and their predictors, and rates of estimated glomerular filtration rate (eGFR) changes among Taiwanese, an ethnic Chinese population, with chronic kidney disease (CKD) stages 3b-5, enrolled in a nationwide pre-end-stage renal disease (pre-ESRD) management program that have not been previously reported. METHODS: This study focused on a cohort of patients enrolled in the Taiwan's pre-ESRD disease management program from Southern Taiwan, including 4061 CKD 3b-5 patients who received more than 12 weeks of follow-up from 2007 to 2010. The decline rates of eGFR, outcomes, and the predictors of initiating dialysis were analyzed. RESULTS: The study participants consisted of patients who were 70.1 ± 12.3 years old, of whom 56.4% were male, 46.3% were diabetic, and 72.1% were hypertensive. The mean annual eGFR changes were 0.47 ± 0.42 mL/min/1.73 m(2)/year, -1.27 ± 0.32 mL/min/1.73 m(2)/year, and -2.69 ± 0.39 mL/min/1.73 m(2)/year for stages 3b, 4, and 5, respectively; however, more rapid declines were noted in diabetic patients. The Kaplan-Meier analyses revealed that the probabilities of patients remaining alive and free of dialysis treatment for CKD stage 3b, 4, and 5 without or with diabetes were 89.46% versus 84.65%, 79.88% versus 55.68%, and 34.42% versus 9.64%, respectively, during 42 months of follow-up. Male gender, diabetes, lower baseline eGFR, higher systolic blood pressure, lower hematocrit, and albumin levels were the significant risk factors for initiating dialysis. CONCLUSION: Even though we cannot conclude with certainty that the Taiwan pre-ESRD disease management program is beneficial in slowing the progression of CKD stages 3b-5, our preliminary results seem to suggest this trend. Furthermore, the program may be improved by integrating it with other programs, such as those on diabetes and hypertension, thus making it a more patient-centered, multidisciplinary program.

To evaluate the prevalence, influencing factors, and behavior rules of self-medication in children. Articles on self-medication in children from various electronic databases (PubMed, Cochrane Library, Web of Science, the WHO website (https://www.who.int/), ABI, CNKI, and Wanfang), were searched to August 2022. The single-group meta-analyses of the prevalence, influencing factors, and behavior rules of self-medication in children were performed using Revman 5.3 and Stata 16.0. The overall pooled prevalence of self-medication in children was 57% (95% CI: 0.39-0.75, I² = 100%, P < .00001 Z = 6.22). The pooled prevalence for main influencing factors, in terms of caregivers, was: 73% (95% CI: 0.72-0.75, I² = 100%, P < .00001, Z = 111.18) for those in rural areas; 55% (95% CI: 0.51-0.59, P = .04, Z = 26.92, I² = 68%, P < .00001) for females; 75% (95% CI: 0.74-0.76, I² = 68%, P < .00001, Z = 106.66) for those whose income was less than 716 dollars; 77% (95% CI: 0.75-0.79, I² = 99%, P < .000001, Z = 92.59) for the middle-aged and elderly; and 72% (95% CI: 0.58-87, I² = 99%, P < .00001, Z = 9.82) for those with a degree below bachelor. In the process of self-medication for children, 19% (95% CI: 0.06-0.32, I² = 99%, P < .00001, Z = 2.82) of the caregivers did not read the instructions, 28% (95% CI: -0.03-0.60, I² = 100%, P < .000001, Z = 1.77) neglected adverse effects, 49% (95% CI: 0.11-0.87, I² = 100%, P = .01, Z = 2.51) spontaneously increased or decreased the dosages, 49% (95% CI: 0.48-0.55, I² = 65%, P < .00001, Z = 16.51) had an awareness of over-the-counter (OTC) drugs, and 41% (95% CI: 0.18-0.64, I² = 99%, P < .00001, Z = 3.49) misrecognized the antibiotics. Self-medication for children was common, although the overall prevalence was not very high. The prevalence of self-medication in children was relatively higher among those caregivers who were female, rural, had low-income, were elder, or had a degree below bachelor. Common behaviors during self-medication in children included spontaneous dose increase or decrease, a lack of awareness of OTC drugs, and misconception of antibiotics. Government departments should formulate corresponding policies to provide quality health education resources for the caregivers of children.

Background: Transnasal humidified rapid-insufflation ventilator exchange (THRIVE) has the characteristics of operating easily and maintaining oxygenation and eliminating CO2, which makes it possible to be used in endoscopic thoracic sympathectomy (ETS). The application of THRIVE in ETS remains undefined. The purpose of this randomized controlled study is to assess the efficacy between THRIVE and laryngeal mask airway (LMA) for ETS. Methods: In total, 34 patients from May 2022 to May 2023 in Huazhong University of Science and Technology Union Shenzhen Hospital undergoing ETS were randomly divided into a THRIVE group (n = 17) and an LMA group (n = 17). A serial arterial blood gas analysis was conducted during the perioperative period. The primary outcome was the arterial partial pressure of carbon dioxide (PaCO2) during the perioperative period. The secondary outcome was arterial partial pressure of oxygen (PaO2) during the perioperative period. Results: The mean (SD) highest PaCO2 in the THRIVE group and LMA group were 99.0 (9.0) mmHg and 51.7 (5.2) mmHg, respectively (p < 0.001). The median (inter-quartile range) time to PaCO2 ≥ 60 mmHg in the THRIVE group was 26.0 min (23.2-28.8). The mean (SD) PaO2 was 268.8 (89.0) mmHg in the THRIVE group and 209.8 (55.8) mmHg in the LMA group during surgery (p = 0.027). Conclusion: CO2 accumulation in the THRIVE group was higher than that of the LMA group during ETS, but THRIVE exhibited greater oxygenation capability compared to LMA. We preliminarily testified that THRIVE would be a feasible non-intubated ventilation technique during ETS under monitoring PaCO2.
RESUMEN
OBJECTIVES: Non-communicable diseases (NCDs) have become the main cause of mortality in China. In 2009, the Chinese government introduced the Basic Public Health Service (BPHS) program to relieve the rising burden of NCDs through public health measures and delivery of essential medical care. The primary aim of this study was to evaluate the impact of the BPHS program on hypertension control. METHODS: The China National Health Development Research Center (CNHDRC) undertook a Cross-sectional Health Service Interview Survey (CHSIS) of 62,097 people from primary healthcare reform pilot areas across 17 provinces from eastern, central, and western parts of China in 2014. The current study is based on responses to the CHSIS survey from 7,867 participants, who had been diagnosed with hypertension. Multi-variable mixed logit regression analysis was used to estimate the association between BPHS management and uncontrolled hypertension. In a follow-up analysis, generalized structural equation modelling (GSEM) was used to test for mediation of the BPHS program effect through patient compliance with medication. FINDINGS: The estimated proportion of patients with uncontrolled hypertension was 30% lower (23.2% vs 31.5%) in those participants who were adequately managed under the BPHS program. Other predictors of hypertension control included compliance with medication, self-reported wellbeing, income, educational attainment and exercise; smoking was associated with reduced hypertension control. The significant inverse association between uncontrolled hypertension and age indicates poor outcomes for younger patients. Additional testing suggested that nearly 40% of the effect of BPHS management (95% CI: 28.2 to 51.7) could be mediated by improved compliance with medication; there was also an indication that the effect of management was 30% stronger in districts/counties with established digital information management systems (IMS). CONCLUSION: Hypertension control improved markedly following active management through the BPHS program. Some of that improvement could be explained by greater compliance with medication among program participants. This study also identified the need to tailor the BPHS program to the needs of younger patients to achieve higher levels of control in this population. Future investigations should explore ways in which existing healthcare management influences the success of the BPHS program.

BACKGROUND: Glutaric acidemia type 1 (GA1) is a treatable disorder affecting cerebral organic acid metabolism caused by a defective glutaryl-CoA dehydrogenase (GCDH) gene. GA1 diagnosis reports following newborn screening (NBS) are scarce in the Chinese population. This study aimed to assess the acylcarnitine profiles and genetic characteristics of patients with GA1 identified through NBS. RESULTS: From January 2014 to September 2020, 517,484 newborns were screened by tandem mass spectrometry, 102 newborns with elevated glutarylcarnitine (C5DC) levels were called back. Thirteen patients were diagnosed with GA1, including 11 neonatal GA1 and two maternal GA1 patients. The incidence of GA1 in the Quanzhou region was estimated at 1 in 47,044 newborns. The initial NBS results showed that all but one of the patients had moderate to markedly increased C5DC levels. Notably, one neonatal patient with low free carnitine (C0) level suggest primary carnitine deficiency (PCD) but was ultimately diagnosed as GA1. Nine neonatal GA1 patients underwent urinary organic acid analyses: eight had elevated GA and 3HGA levels, and one was reported to be within the normal range. Ten distinct GCDH variants were identified. Eight were previously reported, and two were newly identified. In silico prediction tools and protein modeling analyses suggested that the newly identified variants were potentially pathogenic. The most common variant was c.1244-2 A>C, which had an allelic frequency of 54.55% (12/22), followed by c.1261G>A (p.Ala421Thr) at 9.09% (2/22). CONCLUSIONS: Neonatal GA1 patients with increased C5DC levels can be identified through NBS. Maternal GA1 patients can also be detected using NBS due to the low C0 levels in their infants. Few neonatal GA1 patients may have atypical acylcarnitine profiles that are easy to miss during NBS; therefore, multigene panel testing should be performed in newborns with low C0 levels. This study indicates that the GCDH variant spectra were heterogeneous in this southern Chinese cohort.

Carnitine palmitoyltransferase 1A (CPT1A) deficiency is an inherited disorder of mitochondrial fatty acid ß-oxidation that impairs fasting ketogenesis and gluconeogenesis in the liver. Few studies implementing newborn screening (NBS) for CPT1A deficiency in the Chinese population have been reported. This study aimed to determine the biochemical, clinical, and genetic characteristics of patients with CPT1A deficiency in China. A total of 204,777 newborns were screened using tandem mass spectrometry at Quanzhou Maternity and Children's Hospital between January 2017 and December 2018. Newborns with elevated C0 levels were recruited, and suspected patients were subjected to further genetic analysis. Additionally, all Chinese patients genetically diagnosed with CPT1A deficiency were reviewed and included in the study. Among the 204,777 screened newborns, two patients were diagnosed with CPT1A deficiency; thus, the estimated incidence in the selected population was 1:102,388. In addition to the two patients newly diagnosed with CPT1A deficiency, we included in our cohort 10 Chinese patients who were previously diagnosed. Five of these 12 patients were diagnosed via NBS. All patients exhibited elevated C0 and/or C0/(C16+C18) ratios. No clinical symptoms were observed in the five patients diagnosed via NBS, while all seven patients presented with clinical symptoms, including fever, cough, vomiting, diarrhea, and seizures. Eighteen distinct CPT1A variants were identified, 15 of which have been previously reported. The three novel variants were c.272T>C (p.L91P), c.734G>A (p.R245Q), and c.1336G>A (p.G446S). in silico analysis suggested that all three novel variants were potentially pathogenic. The most common variant was c.2201T>C (p.F734S), with an allelic frequency of 16.67% (4/24). Our findings demonstrated that NBS for CPT1A deficiency is beneficial. The three novel variants expand the mutational spectrum of CPT1A in the Chinese population, and c.2201T>C (p.F734S) may be a potential hotspot CPT1A mutation.
