ABSTRACT

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is a progressive disease of unknown etiology with an unpredictable course. We aimed to investigate the effects of the presence of hiatal hernia (HH) and its consequences on the clinical manifestation of IPF.

MATERIALS AND METHODS: Patients diagnosed with IPF with or without hiatal hernia were retrospectively compared in terms of clinical findings, total fibrosis scores (TFS), and lung function in the interstitial lung diseases (ILD) outpatient clinic.

RESULT: A total of 142 IPF patients were included in the study. HH was detected in 62.7% (n= 89) of the patients. There was no statistically significant difference between IPF patients with or without HH in terms of age, gender, smoking history, and anti-reflux drug use (p> 0.05). There was no statistically significant difference between IPF patients with or without HH in terms of symptoms such as dyspnea, cough, regurgitation, heartburn, nausea, dysphagia, chest pain, and hoarseness (p> 0.05). In addition, no statistically significant difference was found between IPF patients with or without HH in terms of mortality rate, survival time after diagnosis, and exacerbations (p> 0.05). Six-minute walking distance and SpO2 change, percentage of predicted forced vital capacity (FVC) value, and percentage of predicted diffusing capacity for carbon monoxide (DLCO) value did not differ significantly between the groups (p> 0.05). There was no statistically significant difference between the groups in terms of total fibrosis score (p= 0.668).

CONCLUSIONS: According to the results of this study, 62.7% (n= 89) of IPF patients had HH, and there was no difference in clinical outcomes, TFS, and pulmonary functions between IPF patients with or without HH.

ABSTRACT

Objective: To analyze the prevalence of allergic rhinitis in Chinese children from 2001 to 2021, in order to provide data support for the prevention and treatment of allergic rhinitis in children. Methods: “Allergic rhinitis” “children” “adolescent” “infant” “prevalence” “epidemiology” were used in the main search terms. The combination of Mesh words and free words was adopted. CNKI, CBM, VIP, WanFang Data, PubMed, Web of Science, Embase and The Cochrane Library for publications between January 1, 2001 and December 31, 2021 were searched systemically and data were extracted from eligible studies by two independent reviewers. Supplementary collection was made by identifying retrospective references from the included literature. After study quality assessment, Meta analysis was completed using Stata 16.0 software. Results: A total of 20 cross-sectional studies were included, involving 54 886 cases. Meta analysis results showed that the overall prevalence of allergic rhinitis among the participants was 18.46% (95%CI:14.34%-22.59%). Subgroup analysis showed that the prevalence of allergic rhinitis from 2012 to 2021 (19.75%) was higher than that from 2001 to 2011 (14.81%), and the difference was statistically significant (P<0.001). The prevalence of different regions from high to low was East China (22.77%), North China (20.82%), Northwest China (17.77%), Central China (16.62%), Southwest China (16.33%), Northeast China (16.16%) and South China (7.29%) respectively, the difference was statistically significant (P<0.001). The prevalence of male (20.73%) was higher than that of female (16.34%), and the difference was statistically significant (P<0.001). The prevalence of Han nationality(17.31%) was higher than that of ethnic minorities (15.93%), and the difference was statistically significant (P<0.001). Conclusion: The prevalence of allergic rhinitis in Chinese children is high and the prevalence in children varies by publication year, region, sex and nationality.

ABSTRACT

Objective: To investigate the efficacy and safety of house dust mite (HDM) allergen subcutaneous specific immunotherapy (SCIT) in patients with allergic rhinitis (AR) with single dust mite allergy and multiple allergen allergy. Methods: A retrospective study was conducted. A total of 372 patients with allergic rhinitis induced by house dust mite were diagnosed in the allergy clinic of General Hospital of North Theater Command from January 2013 to January 2018.They were treated with house dust mite allergen preparation for standardized SCIT for 3 years or more, and had complete follow-up data. The age ranged from 5 to 55 years, the median age was 13 years, and the average age was (19.4±14.7) years; 216 males and 156 females. According to their age, they were divided into the older group (age >14 years) and younger group (age ≤ 14 years). According to the number of allergens, they were divided into single group (only HDM group allergic to house dust mites) and multi recombination (including 2 or more allergens including house dust mites). The multi recombination was further divided into HDM+1 group, HDM+2 group, HDM+3 group, HDM+4 and above group. Before treatment (T0), 1 year (T1) and 3 years (T2) after SCIT treatment, the patients in each group established files, analyzed and compared the average total nasal symptoms score (TNSS), total non nasal symptoms score (TNNSS), visual analogue scale (VAS), total medicine score (TMS) and rhinoconjunctivitis quality of life questionnaire (RQLQ), and evaluated the clinical efficacy of the treatment and the comparison of various scores in the efficacy of SCIT with different allergens and ages. Record the occurrence of local and systemic adverse reactions of all patients during treatment, and evaluate the safety of SCIT. All scores are measurement data that do not conform to normal distribution. Mann-Whitney U and Kruskai-Wallis test of independent samples are used for inter group comparison, and Bonferroni correction is used for further pairwise comparison; Chi square test and continuity correction method were used for the comparison between count data groups such as the incidence of adverse reactions and the effective rate of TNSS, and a-division method was used for further pairwise comparison. Results: After SCIT treatment, the scores of TNSS, TNNSS, TMS, VAS and RQLQ in T1 and T2 were significantly lower than those in T0, and the scores in T2 were significantly lower than those in T1 (Z=-11.168, -4.786, -6.639, -13.012, -10.652 in T0 vs T1; Z=-13.527, -8.746, -13.397, -14.477, -11.833 in T0 vs T2; Z=-4.721, -4.607, -10.020, -7.180, -5.721 in T1 vs T2; P<0.05). In T1 and T2, compared with the older group, the scores of TNSS, TNNSS, TMS, VAS and RQLQ in younger group were lower, and the differences of various indexes were statistically significant(the median scores of T1: M_younger=3.0, 1.0, 2.0, 4.0, 2.6, M_older=5.0, 2.0, 3.0, 5.0, 3.2; the median scores of T2: M_younger=3.0, 1.0, 0, 2.0, 1.3, M_older=4.0, 1.0, 1.5, 3.0, 2.3; Z_T1=-4.525, -5.830, -4.061, -3.608, -2.785; Z_T2=-3.847, -4.055, -2.820, -2.998, -3.418; P<0.05). In T1 and T2, the scores of TNSS, VAS and RQLQ in a single group after SCIT treatment were lower than those in multiple recombination(the median scores of T1:M_single=4.0, 4.0, 2.6, M_multiple=5.0, 5.0, 3.2; the median scores of T2: M_single=3.0, 2.0, 1.4, M_multiple=4.0, 3.0, 2.1), and the difference was statistically significant (Z_T1=-3.002, -2.092, -1.977; Z_T2=-3.354, -2.469, -2.116; P<0.05). There was no significant difference in TMS (the median score during T1 period: M_single=2.0, M_multiple=3.0, Z_T1=-1.130; the median score during T2 period: M_single=1.0, M_multiple=1.0, Z_T2=-1.544; P>0.05). Further comparison within the group showed that there was no significant difference in the improvement rate of TNSS during T2 period among HDM group, HDM+1 group, HDM+2 group and HDM+3 group (HDM vs HDM+1 group χ²=0.277, HDM vs HDM+2 group χ²=0.78, HDM vs HDM+3 group χ²=0.075, HDM+1 vs HDM+2 group χ²=0.057, HDM+1 vs HDM+3 group χ²=0.019, HDM+2 vs HDM+3 group χ²=0.003; P>0.005), the improvement rates were 92.5%, 90.3%, 89.1% and 89.5%. Respectively in HDM group,HDM+1 group, HDM+2 group, HDM+3 group, compared with HDM+4 and above group, the difference was statistically significant (χ²=26.144, 13.254, 15.144, 8.808; P<0.005). The improvement rate of TNSS in HDM+4 and above group was 60.9%. 122 patients had local adverse reactions during the treatment of SCIT, accounting for 32.8%. The local adverse reactions were 759 injections (15 336 injections in total), accounting for 4.95%. Most of them were swelling, dizziness, induration and pruritus at the injection site, which could be relieved by oral antihistamines or within 2 hours. There were 2 cases of local urticaria, once for each case. The symptoms were relieved within 1 week after oral antihistamine. No serious systemic adverse reactions occurred. Conclusion: Standardized SCIT may be a safe and effective treatment for AR patients, and the type of allergen may be one of the important factors affecting the efficacy of SCIT. The efficacy of SCIT was significant in AR patients with three or less allergens other than house dust mite.

ABSTRACT

Objective: To analyze the sensitization characteristics and change of major allergens in children from 2010 to 2020 in Beijing, so as to provide basis for diagnosis, treatment and prevention of allergic diseases in children. Methods: A retrospective study was conducted to analyze the children who were suspected of allergic diseases and tested for serum immunoglobulin E (total IgE and specific IgE) in the children’s Hospital Affiliated to the Capital Institute of Pediatrics from January 2010 to December 2020. A total of 45 746 children aged 0-17 years in Beijing were enrolled with a median (interquartile range) of 3.8 (2.5, 5.3) years. There were 28 918 boys (63.2%) and 16 828 girls (36.8%) and 14 984 cases (32.8%) in the infant group (<3 years old), 22 049 cases (48.2%) in the preschool group (3-6 years old), and 8 713 cases (19.0%) in the school-age group (6 years old and above). Immunocap allergen detection system (fluorescence enzyme-linked immunosorbent assay) was used to detect and the characteristics and change trend of allergens during 11 years were statistically analyzed by Chi square test. Results: The top three positive rates of single food allergens sIgE were egg white 42.6% (2 788/6 577 tests), milk 38.4% (2 606/6 782 tests) and wheat 31.8% (1 417/4 449 tests), and the sequence of single inhaled allergens were Ragweed 42.6% (440/1 034 tests), Artemisia 38.4% (1 045/3 191 tests) and Alternaria alternata 31.3% (3 358/10 725 tests). The positive detection rates of egg white 47.0%(1 904/4 048 tests), milk 41.9%(1 769/4 226 tests) and wheat 33.9%(973/2 870 tests) in the infant group were the highest, and there have statistically significant(χ²=91.495, 73.907, 16.966, P<0.05). The positive rates of fx1 (22.5%, 121/537 tests), peanut (24.9%, 111/446 tests), soybean (20.0%, 74/370 tests) and shrimp (7.48%, 44/588 tests) were the highest in the school-age group(χ²=14.436, 10.751, 11.569, 13.703, P<0.05). The most common inhaled allergens were Alternaria alternata (14.8%, 422/2 859 tests) in the infant group, Ambrosia (34.5%, 143/415 tests) and Alternaria alternata (33.5%, 1 762/5 254 tests) in the preschool group, while in the school-age group were Ambrosia (56.4%, 282/500 tests) and Artemisia (48.2%, 573/1 189 tests). The positive rates of egg white, milk, wheat, sesame seed and peanut varied from 2010 to 2020, showing a trend of falling first and then rising(χ²=10.293,χ²=12.066,χ²=7.402,χ²=32.458,χ²=31.747,P<0.05).The positive detection rates of soybean showed a significant downward trend (21.4%, 173/809 tests in 2010, 15.4%, 70/455 tests in 2020, χ²=6.751,P=0.009), while that of shrimp and crab were at a stable low level(χ²=0.263, 1.346;P>0.05). From 2010 to 2020, mold (26.7%, 1 066/3 998 tests in 2010, 40.2% 1 705/4 243 tests in 2020), grass pollen (19.8%, 259/1 308 tests in 2010, 39.3%, 1 472/3 746 tests in 2020), tree pollen(17%, 180/1 058 tests in 2010, 29.8%, 916/3 075 tests in 2020) and animal dander (18.5%, 111/601 tests in 2010, 26.6%, 672/2 522 tests in 2020) were all showed significant upward trend (χ²=168.600, 163.601, 65.931 and 17.271 respectively, P<0.001) but dust mites (30.7%, 1 270/4 132 tests in 2010, 26.7%, 1 126/4 221 tests in 2020) showed a significant downward trend(χ²=16.822,P<0.001).In 2010, the most common inhaled allergen was dust mite 30.7% (1 270/4 132 tests), followed by mold 26.7% (1 066/3 998 tests), while they were mold 40.2% (1 705/1 243 tests), and grass pollen 39.3% (1 472/3 746 texts) respectively in 2020. Conclusion: In the past 11 years, the main food allergens in children were still egg white and milk, wheat, but the mold and pollen gradually replaced dust mite as the most common inhaled allergen.

ABSTRACT

Objective: To compare the specific IgE positive rates of the patients between allergic respiratory diseases and respiratory infectious diseases in Guangzhou, the relationship between the co-sensitization of house dust mite (HDM) allergen and Aspergillus fumigatus (AF) allergen and asthma, allergic rhinitis with asthma, pneumonia, upper respiratory infections, bronchitis, serum total immunoglobulin E (total Immunoglobulin E, tIgE) and age were analyzed, to provide the basis for the prevention and treatment of respiratory allergic diseases and respiratory infectious diseases in this area. Methods: A total of 2 535 patients with confirmed respiratory allergic diseases and respiratory infectious diseases were selected retrospectively from the outpatient or inpatient department of the First Affiliated Hospital of Guangzhou Medical University from April 2017 to June 2021 and detected HDM and AF specific IgE (sIgE) by the ImmunoCAP system. The age range was 1 to 89 years. The median age was 5 years. The average age was 9. ≤3 years old group n=894, 4-6 years old group n=721, 7-18 years old group n=615, 19-49 years old group n=207, >49 years old group n=98. There were 1 596 males (62.96%) and 939 females (37.04%). There were 1 279 cases of allergic diseases and 1 256 cases of respiratory infectious diseases. The different disease groups were divided into asthma group (411 cases), allergic rhinitis group (458 cases), allergic rhinitis combined with asthma group (410 cases), pneumonia group (463 cases), upper respiratory tract infection group (299 cases) and bronchitis group (494 cases). The difference of specific IgE (sIgE) and tIgE between HDM and AF was analyzed. For statistical analysis, continuous variables were tested by Mann-Whitney U. Classification data by chi-square test or Fisher’s exact test. Results: 1 313 (51.79%) patients were sIgE positive for HDM allergen, 65 (2.56%) were sIgE positive for AF allergen, and 50 (1.97%) were both positive. In the respiratory allergic disease group, 877 cases (68.57%,877/1 279) were positive for HDM allergen sIgE, 57 cases (4.46%,57/1 279) were positive for AF allergen sIgE, and 44 cases (3.44%,44/1 279) were both positive; 436 cases (34.71%,436/1 256) of respiratory infectious diseases were positive for HDM allergen sIgE, 8 cases (0.64%,8/1 256) were positive for AF allergen sIgE, and 6 cases (0.48%,6/1 256) were both positive. In monosensitization, the HDM allergen sIgE sensitization rate was the highest in the allergic rhinitis & asthma group, at 80.24% (329/410). The positive rate of HDM allergen sIgE in male patients was 53.76%(858/1 596), and the positive rate in female patients was 46.22%(434/939), and the difference between the two was statistically significant (χ²=13.449, P<0.001). In polysensitization, asthma patients (5.35%,22/411) had the highest positive rate of HDM sensitization with AF, followed by allergic rhinitis patients (3.06%,14/458), allergic rhinitis with asthma (1.95%,8/410). The positive rate of respiratory infectious diseases such as pneumonia (0.43%,2/463), upper respiratory infections (0.33%,1/299), and bronchitis (0.61%,3/494) with AF was extremely low. The positive rate of HDM combined with AF in infants(≤3 years old group,0.34%, 3/894; 4-6 years old group, 0.97%, 7/721)was significantly lower than that in teenagers and adults(7-18 years old group,3.58%, 22/615; 19-49 years old group,6.28%, 13/207;>49 years old group,5.10%, 5/98).In the patients with HDM and AF combined sensitization, HDM sIgE levels were distributed in all grades, and AF sIgE levels were mainly in grades 1, 2, and 3. Conclusion: The positive rate of HDM combined with AF was higher in patients with respiratory allergic diseases such as asthma, allergic rhinitis, and allergic rhinitis combined with asthma, suggesting that clinical attention should be paid to the combination of HDM and AF in patients with asthma and allergic rhinitis, especially adults, more likely to be combined with AF.

ABSTRACT

Working memory (WM) impairment is one of the most frequent cognitive deficits in Parkinson’s disease (PD). However, it is not known how neural activity is altered and compensatory responses eventually fail during progression. We aimed to elucidate neural correlates of WM and compensatory mechanisms in PD. Eighteen cognitively normal PD patients (PD-CogNL), 16 with PD with mild cognitive impairment (PD-MCI), 11 with PD with dementia (PDD), and 17 healthy controls (HCs) were evaluated. Subjects performed an n-back task. Functional MRI data were analyzed by event-related analysis for correct responses. Brain activations were evaluated by comparing them to fixation cross or 0-back task, and correlated with n-back task performance. When compared to fixation cross, PD-CogNL patients had more activation in WM areas than HCs for both the 2- and 3-back tasks. PD-MCI and PDD patients had more activation in WM areas than HCs for the 0- and 1-back task. 2-back task performance was correlated with brain activations (vs. 0-back task) in the bilateral dorsolateral prefrontal cortex and frontal eye field (FEF) and left rostral prefrontal cortex, caudate nucleus, inferior/superior parietal lobule (IPL/SPL), and anterior insular cortex as well as anterior cingulate cortex. 3-back task performance was correlated with brain activations (vs. 0-back task) in the left FEF, right caudate nucleus, and bilateral IPL/SPL. Additional activations on top of the 0-back task, rather than fixation cross, are the neural correlates of WM. Our results suggest PD patients have two types of compensatory mechanisms: (1) Hyperactivation for different WM load tasks depending on their cognitive status. PD-CogNL have hyperactivation for moderate and heavy working memory load tasks while maintaining normal working memory performance. In contrast, PD-MCI and PDD have hyperactivation for control task and light working memory load task, leaving less neural resources to further activate for more demanding tasks and resulting in impaired working memory performance. (2) Bilateral recruitment of WM-related areas, in particular the DLPFC, FEF, IPL/SPL and caudate nucleus, to improve WM performance.

ABSTRACT

BACKGROUND: Machine learning (ML), a type of artificial intelligence (AI) technology that uses a data-driven approach for pattern recognition, has been shown to be beneficial for many tasks across healthcare. To characterize the commercial availability of AI/ML applications in the clinic, we performed a detailed analysis of AI/ML-enabled medical devices approved/cleared by the US Food and Drug Administration (FDA) by June 2021.

METHODS/MATERIALS: The publicly available approval letters by the FDA on 343 AI/ML-enabled medical devices compiled by the agency were reviewed. The characteristics of the devices and the patterns of their intended use were analyzed, and basic descriptive statistical analysis was performed on the aggregated data.

RESULTS: Most devices were reviewed by radiology (70.3%) and cardiovascular (12.0%) medical specialty panels. The growth of these devices sharply rose since the mid-2010s. Most (95.0%) devices were cleared under the 510(k) premarket notification pathway, and 69.4% were software as a medical device (SaMD). Of the 241 radiology-related devices, the most common applications were for diagnostic assistance (48.5%) and image reconstruction (14.1%). Of the 117 radiology-related devices for diagnostic assistance, 20.5% were developed for breast lesion assessment and 14.5% for cardiac function assessment on echocardiogram. Of the 41 cardiology-related devices, the most common applications were electrocardiography-based arrhythmia detection (46.3%) and hemodynamics & vital signs monitoring (26.8%).

CONCLUSION: In this study, we characterized the patterns and trends of AI/ML-enabled medical devices approved or cleared by the FDA. To our knowledge, this is the most up-to-date and comprehensive analysis of the landscape as of 2021.

ABSTRACT

The water quality of the northern Caspian Sea has not been well-known, and its contamination can adversely affect the health of swimmers and seashore residents. The study sought to determine the contamination state of the Caspian Sea in Kazakhstan and quantify human health risks coming from the existing heavy metals concentration. The Caspian Sea was found to be “fairly to marginally” contaminated (24 < CCME-WQI < 64), with Cd influencing the index significantly. Concentrations of Cd and Pb increase over time (seasonal Kendall test, p-values = 2-4 %) in sites near oil fields and ports, suggesting the significant role of anthropogenic sources in causing diverse pollution events. Pb demonstrated the highest variability and number of outliers (4.3 % of all samples with coefficients of variation reaching up to 175 %). The principal component analysis further revealed that various discharges from oilfields and upstream transport could contribute to the contamination by heavy metals and their concentrations. Contamination is associated with up to 6 % cancer risk for adults. The long exposure duration of swimmers in water increases risks by up to 18 %, indicating the local population is at a higher risk. In conclusion, statistical tests and analysis indicate the presence of anthropogenic sources, and risk assessment reveals swimming can contribute to cancer risk.

ABSTRACT

RESEARCH QUESTION: The purpose of this study is to investigate whether the mitochondrial DNA (mtDNA) content can reflect the state of mosaic embryos.

DESIGN: The study included 1669 blastocysts derived from 394 PGT-A cycles between January 2018 and December 2020, in which preimplantation genetic testing for aneuploidy was performed and mtDNA content was determined. The standard deviation (SD) of whole genomic sequencing data was calculated for quality control. mtDNA content was measured as the proportion of mtDNA to genomic DNA. 1558 blastocysts with SD values less than 4.0 and mtDNA values less than 0.4% were selected for statistical analysis.

RESULTS: The mtDNA content of the PGT mosaic group was significantly higher than that of the PGT normal group (P < 0.001). Twenty-six mosaic embryos were transferred, and the results were as follows: 2 out of 26 had undergone a spontaneous miscarriage, 15 were not pregnant, and 9 resulted in a live birth. There were significant differences in the mtDNA content between the miscarriage/non-pregnancy group and the live birth group (**P < 0.01; ***P < 0.001). There was no mosaic embryo with more than 0.157% mtDNA content found in the live birth group.

CONCLUSIONS: This study demonstrates that mtDNA analysis has the ability to identify mosaic embryos with high developmental potential. It can be a valuable supplementary index for the selection of mosaic embryos for transfer. Larger studies with a greater sample size will further our understanding of the relationships between metabolic activity and mosaicism.

Nephrotoxicity is one of the most severe late-term side effects after chemotherapy. It is important to evaluate the possible risks and provide valuable treatment and follow-up for the patient.

METHODS: the data was observed from 50 patients from 0 till 18 years old that were treated for childhood cancer and was collected according to methodological recommendations.

RESULTS: 28 boys and 22 girls were included and the average age of all patients when the diagnosis was made was five years. 56% have faced kidney and urinary tract related complications. 75% of those patients have faced nephrotoxicity, 10,71 – urinary tract related complications and 14,29 have faced both – nephrotoxicity and urinary tract related complications. GFR was decreased in one case, increased in three cases and normal in the remaining cases. There was no statistical significance between kidney and urinary tract related complications and patient’s age at the time of treatment, type of cancer (except for sarcomas), type of surgery or radiotherapy. Nephrotoxicity had statistical significance to occur more commonly during the first two years after treatment, while urinary tract related complications occurred more frequently during five years after treatment. Doxorubicin and Ifosfamide had statistical significance with kidney-related long-side effect; Lomustine also had a close relation. Chemotherapy drug’s cumulative dose also had statistical significance of the same chemotherapy drugs.

CONCLUSIONS: this study suggests that chemotherapy drug and its cumulative dosage has the most influence on kidney and urinary tract related complications.
