A nomogram based on clinical factors and CT radiomics for predicting anti-MDA5+ DM complicated by RP-ILD.

OBJECTIVES: Anti-melanoma differentiation-associated gene 5 antibody-positive (anti-MDA5+) DM complicated by rapidly progressive interstitial lung disease (RP-ILD) has a high incidence and poor prognosis. The objective of this study was to establish a model for the prediction and early diagnosis of anti-MDA5+ DM-associated RP-ILD based on clinical manifestations and imaging features. METHODS: A total of 103 patients with anti-MDA5+ DM were included. The patients were randomly split into training and testing sets of 72 and 31 patients, respectively. After image analysis, we collected clinical, imaging and radiomics features from each patient. Feature selection was performed first with the minimum redundancy and maximum relevance algorithm and then with the best subset selection method. The final remaining features comprised the radscore. A clinical model and imaging model were then constructed with the selected independent risk factors for the prediction of non-RP-ILD and RP-ILD. We also combined these models in different ways and compared their predictive abilities. A nomogram was also established. The predictive performances of the models were assessed based on receiver operating characteristics curves, calibration curves, discriminability and clinical utility. RESULTS: The analyses showed that two clinical factors, dyspnoea (P = 0.000) and duration of illness in months (P = 0.001), and three radiomics features (P = 0.001, 0.044 and 0.008, separately) were independent predictors of non-RP-ILD and RP-ILD. However, no imaging features were significantly different between the two groups. The radiomics model built with the three radiomics features performed worse than the clinical model and showed areas under the curve (AUCs) of 0.805 and 0.754 in the training and test sets, respectively. The clinical model demonstrated a good predictive ability for RP-ILD in MDA5+ DM patients, with an AUC, sensitivity, specificity and accuracy of 0.954, 0.931, 0.837 and 0.847 in the training set and 0.890, 0.875, 0.800 and 0.774 in the testing set, respectively. The combination model built with clinical and radiomics features performed slightly better than the clinical model, with an AUC, sensitivity, specificity and accuracy of 0.994, 0.966, 0.977 and 0.931 in the training set and 0.890, 0.812, 1.000 and 0.839 in the testing set, respectively. The calibration curve and decision curve analyses showed satisfactory consistency and clinical utility of the nomogram. CONCLUSION: Our results suggest that the combination model built with clinical and radiomics features could reliably predict the occurrence of RP-ILD in MDA5+ DM patients.

Molecular and clinical profile of rare bleeding disorders: A single-center retrospective study.

INTRODUCTION: Due to their low frequency, there is little information on the molecular pathologies of rare bleeding disorders (RBD). Therefore, this study aimed to analyze the molecular and clinical profiles of patients with RBD. METHODS: A retrospective single-center study was conducted among patients with factor (F) II, FVII, FX, and FXIII deficiencies between March 20, 2000, and June 31, 2023. Data on patient demographics, genetic analysis, and laboratory results were documented for all patients. The disease severity was classified according to the clotting factor activity (except FXIII) as follows: >5%: mild, 1-5%: moderate, and <1%: severe. RESULTS: A total of 79 patients were enrolled in this study. Three of the cases had FII (3.7%), 40 had FVII (50.6%), 20 had FX (25.3%), and 16 had FXIII deficiency (20.2%). The median age of the patients at the time of diagnosis was six months for FII, 6.5 years for FVII, five months for FX, and 5.75 months for FXIII deficiencies, respectively. The major clinical manifestations were bruising, epistaxis, oral cavity bleeding, ecchymosis, and hemarthrosis. Consanguinity was present in 60 (76%) of patients. The majority of the patients had missense mutations. FVII mutations occurred primarily in exon 6, FX mutations affected mainly exons 2 and 7, and the majority of FXIII mutations occurred in exons 3 and 4. CONCLUSION: The diagnosis of the causative mutations in patients with RBD provides an insight into the underlying molecular basis of these disorders and probably explains their variable clinical manifestations.

Onychomycosis due to Fusarium species in different continents, literature review on diagnosis and treatment.

Fusarium species are an emerging cause of onychomycosis, and the number of cases has dramatically increased in recent decades worldwide. This review presents an overview of the onychomycosis cases caused by Fusarium species and diagnosis and treatment that have been reported in the literature. The most common causative agent of onychomycosis is F. solani species complex, which accounts for 11.68% of the cases of Fusarium onychomycosis, followed by the F. oxysporum species complex (164 out of 1669), which is accounted for 9.83% of the total. F. fujikuroi species complex (42 out of 1669) and F. dimerum species complex (7 out of 1669) are responsible for 2.52% and 0.42 cases, respectively. Fusarium nail infections were reported in patients aged range 1-98, accounting for 5.55% (1669 out of 30082) of all cases. Asia has the highest species diversity of Fusarium onychomycosis (31.51%). South America accounts for 21.09%, and the most common causative agent is F. solani (19.32%), followed by F. oxysporum species complex (15.63%). Europe accounts for 4.90% of cases caused by F. oxysporum, followed by F. solani. Africa accounts for 23.87% of the cases due to the F. solani species complex, followed by F. oxysporum and F. fujikuroi. Distal and lateral subungual onychomycosis was the most common clinical symptom accounting for 58.7% (135 out of 230) of the cases. Data analysis relieved that terbinafine and itraconazole are active treatments for Fusarium onychomycosis. For a definitive diagnosis, combining of direct examination, culture and sequencing of the elongation factor of translation 1α are recommended. Accurate identification of the causative agents of onychomycosis due to Fusarium species and antifungal susceptibility testing is essential in patient management.

The association between potential predictors and death of patients during the COVID-19 pandemic in Shiraz: a hierarchical multiple regression analysis.

INTRODUCTION: Identifying clinical factors that increase the risk of mortality in COVID-19 patients is crucial. This enables targeted screening, optimizing treatment, and prevention of severe complications, ultimately reducing death rates. This study aimed to develop prediction models for the death of patients (i.e., survival or death) during the COVID-19 pandemic in Shiraz, exploring the main influencing factors. METHOD: We conducted a retrospective cohort study using hospital-based records of 1030 individuals diagnosed with COVID-19, who were hospitalized for treatment between March 21, 2021, and March 21, 2022, in Shiraz, Iran. Variables related to the final outcome were selected based on criteria and univariate logistic regression. Hierarchical multiple logistic regression and classification and regression tree (CART) models were utilized to explore the relationships between potential influencing factors and the final outcome. Additionally, methods were employed to identify the high-risk population for increased mortality rates during COVID-19. Finally, accuracy was evaluated the performance of the models, with the area under the receiver operator characteristic curve(AUC), sensitivity, and specificity metrics. RESULTS: In this study, 558 (54.2%) individuals infected with COVID-19 died. The final model showed that the type of medicine antiviral (OR: 11.10, p = 0.038) than reference (antiviral and corticosteroid), and discharge oxygen saturation(O2) (OR: 1.10, p < 0.001) had a positive association with the chance of survival, but other variables were not considered as predictive variables. Predictive models for the final outcome(death) achieved accuracies ranging from 81 to 87% for hierarchical multiple logistic regression and from 87 to 94% for the CART model. Therefore, the CART model performed better than the hirerical multiple logistic regression model. CONCLUSION: These findings firstly elucidate the incidence and associated factors of the outcome (death) among patients in Shiraz, Iran. Furthermore, we demonstrated that antiviral medication alone (without corticosteroids) and high O2 increase the survival chances of COVID patients.

Clinical, pathological and genetic characteristics of 17 unrelated children with Alagille Syndrome.

BACKGROUND: Alagille syndrome (ALGS) is a multisystem genetic disorder frequently characterized by hepatic manifestations. This study analyzed the clinical, pathological, and molecular genetic features of ALGS to improve the efficiency of clinical diagnosis. METHODS: We retrospectively analyzed the clinical manifestations, pathological examination findings, and genetic testing results of 17 children diagnosed with ALGS based on the revised criteria and hospitalized at our center from January 2012 to January 2022. RESULTS: The clinical manifestations are as follows: Cholestasis (16/17, 94%), characteristic facies (15/17, 88%), heart disease (12/16, 75%), butterfly vertebrae (12/17, 71%) and posterior embryotoxon (7/12, 58%). Among the 15 patients who underwent liver pathology examination, 13 (87%) were found to have varying degrees of bile duct paucity. Genetic testing was performed on 15 children, and pathogenic variants of the jagged canonical Notch ligand 1 (JAG1) gene were identified in 13 individuals, including 4 novel variants. No pathogenic variant in the notch homolog 2 (NOTCH2) gene were identified, and 2 children exhibited none of the aforementioned gene pathogenic variants. The median follow-up duration was 7 years. Of the remaining 15 patients (excluding 2 lost to follow-up), 11 remained stable, 4 deteriorated, and no patient died during the follow-up period. CONCLUSIONS: Among children diagnosed with ALGS, cholestasis stands as the most common feature. To minimize the risk of misdiagnosis, genetic testing should be performed on children exhibiting cholestasis, followed by the application of the revised diagnostic criteria for ALGS. While pharmacological therapy has shown effectiveness for ALGS patients, liver transplantation may be considered in instances of severe pruritus.

Effect of COVID-19 infection on pregnant women in plateau regions.

OBJECTIVE: The present study aims to explore the effect of COVID-19 infection on pregnant women in plateau regions. STUDY DESIGN: Data from 381 pregnant women infected with COVID-19 who underwent prenatal examination or treatment at Women and Children's Hospital of Tibet Autonomous Region between January 2020 and December 2022 and 314 pregnant women not infected with COVID-19 were retrospectively collected. METHODS: The study participants were divided into an infected and non-infected group according to whether they were infected with COVID-19. Basic information (ethnicity, age, body mass index and gestational age [GA]), vaccination status, intensive care unit (ICU) admission and delivery outcomes were compared. Binary logistic regression was used to analyse the influencing factors of ICU admission. RESULTS: The results revealed significant differences in the GA, vaccination rate, blood pressure, partial pressure of oxygen, white blood cell (WBC) count, ICU admission rate, preeclampsia rate, forearm presentation rate, thrombocytopenia rate, syphilis infection rate and placental abruption rate between the two groups (P < 0.05). A univariate analysis showed that COVID-19 infection, hepatitis B virus infection, the WBC count and hypoproteinaemia were risk factors for ICU admission. The results of the multivariate analysis of the ICU admission of pregnant women showed that COVID-19 infection (odds ratio [OR] = 4.271, 95 % confidence interval [CI]: 3.572-5.820, P < 0.05) was a risk factor for ICU admission and the WBC count (OR = 0.935, 95 % CI: 0.874-0.947, P < 0.05) was a protective factor for ICU admission. CONCLUSION: Pregnant women are vulnerable to the adverse consequences of COVID-19 infection, and public health measures such as vaccination are needed to protect this population subgroup.

[Research progress on the manifestations and prognosis of neonatal lupus erythematosus in various systems]. / æ–°ç”Ÿå„¿çº¢æ–‘ç‹¼ç–®å„ç³»ç»Ÿè¡¨çŽ°åŠé¢„åŽç ”ç©¶è¿›å±•.

Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

[Clinical characteristics of children with anti-neutrophil cytoplasmic antibody-associated vasculitis]. / å„¿ç«¥æŠ—ä¸­æ€§ç²’ç»†èƒžèƒžè´¨æŠ—ä½“ç›¸å ³æ€§è¡€ç®¡ç‚Žä¸´åºŠç‰¹å¾åˆ†æž.

OBJECTIVES: To study the clinical characteristics of children with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: A retrospective analysis was conducted on the clinical data of 25 children diagnosed with AAV at the Second Xiangya Hospital of Central South University from January 2010 to June 2022. RESULTS: Among the AAV children, there were 5 males and 20 females, with a median age of onset of 11.0 years. Involvement of the urinary system was seen in 18 cases (72%); respiratory system involvement in 10 cases (40%); skin involvement in 6 cases (24%); eye, ear, and nose involvement in 5 cases (20%); joint involvement in 4 cases (16%); digestive system involvement in 2 cases (8%). Eleven cases underwent kidney biopsy, with 5 cases (46%) showing focal type, 2 cases (18%) showing crescentic type, 2 cases (18%) showing mixed type, and 2 cases (18%) showing sclerotic type. Immune complex deposits were present in 5 cases (45%). Seven cases reached chronic kidney disease (CKD) stage V, with 2 cases resulting in death. Two cases underwent kidney transplantation. At the end of the follow-up period, 2 cases were at CKD stage II, and 1 case was at CKD stage III. Of the 16 cases of microscopic polyangiitis (MPA) group, 13 (81%) involved the urinary system. Of the 9 cases of granulomatosis with polyangiitis (GPA), 6 cases (66%) had sinusitis. Serum creatinine and uric acid levels were higher in the MPA group than in the GPA group (P<0.05), while red blood cell count and glomerular filtration rate were lower in the MPA group (P<0.05). CONCLUSIONS: AAV is more common in school-age female children, with MPA being the most common clinical subtype. The onset of AAV in children is mainly characterized by renal involvement, followed by respiratory system involvement. The renal pathology often presents as focal type with possible immune complex deposits. Children with MPA often have renal involvement, while those with GPA commonly have sinusitis. The prognosis of children with AAV is poor, often accompanied by renal insufficiency.

[Clinical diagnosis of group A streptococcal pharyngitis and progress in the application of scoring systems]. / A族链球菌咽炎的临床诊断及评分制的应用进展.

Pharyngitis can be caused by various pathogens, including viruses and bacteria. Group A streptococcus (GAS) is the most common bacterial cause of pharyngitis. However, distinguishing GAS pharyngitis from other types of upper respiratory tract infections is challenging in clinical settings. This often leads to empirical treatments and, consequently, the overuse of antimicrobial drugs. With the advancement of antimicrobial drug management and healthcare payment reform initiatives in China, reducing unnecessary testing and prescriptions of antimicrobial drugs is imperative. To promote standardized diagnosis and treatment of GAS pharyngitis, this article reviews various international guidelines on the clinical diagnosis and differential diagnosis of GAS pharyngitis, particularly focusing on clinical scoring systems guiding laboratory testing and antimicrobial treatment decisions for GAS pharyngitis and their application recommendations, providing a reference for domestic researchers and clinical practitioners.

Purine Nucleoside Phosphorylase Deficient Severe Combined Immunodeficiencies: A Case Report and Systematic Review (1975-2022).

Purine nucleoside phosphorylase deficient severe combined immunodeficiency (PNP SCID) is one of the rare autosomal recessive primary immunodeficiency disease, and the data on epidemiology and outcome are limited. We report the successful management of a child with PNP SCID and present a systematic literature review of published case reports, case series, and cohort studies on PNP SCID listed in PubMed, Web of Science, and Scopus from 1975 until March 2022. Forty-one articles were included from the 2432 articles retrieved and included 100 PNP SCID patients worldwide. Most patients presented with recurrent infections, hypogammaglobulinaemia, autoimmune manifestations, and neurological deficits. There were six reported cases of associated malignancies, mainly lymphomas. Twenty-two patients had undergone allogeneic hematopoietic stem cell transplantation with full donor chimerism seen mainly in those receiving matched sibling donors and/or conditioning chemotherapy before the transplant. This research provides a contemporary, comprehensive overview on clinical manifestations, epidemiology, genotype mutations, and transplant outcome of PNP SCID. These data highlight the importance of screening for PNP SCID in cases presented with recurrent infections, hypogammaglobulinaemia, and neurological deficits.

Comparison of clinical manifestations in mpox patients living with HIV versus without HIV: A systematic review and meta-analysis.

Currently, many cases of mpox patients living with the human immunodeficiency virus (HIV) have been reported. Immunocompromised mpox patients, including those living with HIV are noted for an increased risk for severe symptoms; however, existing studies did not focus on the statistical comparison of mpox outcomes associated with HIV. Thus, we conducted a systematic review and meta-analysis to evaluate and compare the clinical manifestations of mpox in people living with HIV (PLWH) and people without HIV. In this systematic review and meta-analysis, PubMed/MEDLINE, Embase, and Google Scholar were searched up to March 7, 2023. A random effects model was used to calculate the pooled prevalence along with the 95% confidence intervals (CI), and the odds ratio and its corresponding 95% CIs were calculated to elucidate the significance of each clinical feature for mpox patients with and without HIV. In this study, we included 99 published papers with 2413 patients with mpox (median age, 35.5 years; PLWH n = 1151) from 27 countries across six continents. The odds ratio of the mpox outcomes with PLWH in comparison to patients without HIV was found to be significant for skin rash (1.24, 95% CI: 1.01-1.53), proctitis (2.03, 95% CI: 1.36-3.04), cough (0.57, 95% CI: 0.33-0.98), and diarrhea (3.85, 95% CI: 1.24-11.98). The odds ratio of mpox patients with HIV for historical infections of syphilis was 2.14 (95% CI: 1.38-3.32), compared with those without HIV. This is the first international and comprehensive study that performed a systematic review and meta-analysis to statistically measure mpox manifestations according to HIV status. As clinical features related to mucosal contact were characteristically pronounced in PLWH, our systematic review provides insight that the primary invasion site of infection strongly relates to the outcomes of mpox.

Spinocerebellar Ataxia Type 10 with Atypical Clinical Manifestation in Han Chinese.

Spinocerebellar ataxia type 10 (SCA10) is an autosomal dominant cerebellar ataxia accompanied by extracerebellar signs and other neurological disorders. It is caused by an expansion of the ATTCT pentanucleotide repeat in intron 9 of ATXN10. Cases of SCA10, formerly confined to America, have been reported in Europe and Asia. In the present study, we aim to report an atypical SCA10 family in China and provide a reference for the diagnosis of SCA10 in Asia by comparing their clinical and genetic features with former SCA10 pedigrees. Genomic DNA was extracted from patients and subjected to RP-PCR (repeat-primed PCR), Southern blotting, and haplotype analysis to determine the genetic pathogenesis. Patients with SCA10 in this pedigree demonstrated atypical SCA10 manifestations, including the absence of seizures and ocular abnormalities. Magnetic resonance imaging (MRI) showed cerebellar atrophy in five patients with available data. RP-PCR and Southern blotting revealed abnormal expansion. Analysis of single nucleotide polymorphisms (SNPs) surrounding the SCA10 locus in the proband and other affected family members revealed the "C-expansion-G-G-C" haplotype, consistent with former studies. These findings imply that the SCA10 mutation may have occurred before the Amerindian migration from East Asia to North America. It also suggested that SCA10 should be taken into account during differential diagnosis in patients of Asian ancestry, even if they do not present with typical features such as epilepsy.

Multicenter analysis of epidemiological and clinical features of pediatric acute lower respiratory tract infections associated with common human coronaviruses in China, 2014-2019.

The common human coronaviruses (HCoVs) HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1 which are members of the coronavirus family are long co-existed with humans and widely distributed globally. Common HCoVs usually cause mild, self-limited upper respiratory tract infections (URTI), and also associated with lower respiratory tract infections (LRTI), especially in children. However, there are little multicentre studies have been conducted in children of several different areas in China, and the epidemic potential of common HCoVs remains unclear. Understanding of the common HCoVs is valuable for clinical and public health. Herein, we retrospectively analysed the medical records of children with acute lower respiratory tract infection admitted to 9 hospitals from different regions in China from 2014 to 2019. Of the 124 patients who tested positive for coronaviruses, OC43 was the predominant type, accounting for 36.3% (45/124) of the detections. Children aged ≤ 6 months and 12-23 months had the highest detection rate of common HCoVs, and the detection rate gradually declined after 2 years old. These four HCoVs could be detected all year round. Among the areas of our study, the overall positive rate was higher in southern China, especially in Guangzhou (29/124, 23.4%). Moreover, common HCoV-positive patients were codetected with 9 other common respiratory pathogens. 229E (11/13, 84.6%) was the most frequently associated with codetection, with EV/RhV was the most frequently codetected virus. Cough (113/124, 91.1%) and fever (73/124, 58.9%) were the most common symptoms of common HCoVs infection.

Clinical manifestations and early effectiveness of methimazole in patients with graves' hyperthyroidism-related severe hepatic dysfunction.

BACKGROUND: Graves' hyperthyroidism (GH) is often accompanied by mild to moderate liver injury, but severe hepatic dysfunction (SHD) is relatively rare. Whether patients with GH-related SHD can be treated with methimazole (MMI) remains controversial. This study aimed to determine the clinical characteristics and to evaluate the role of low-dose MMI for such patients. METHODS: 33 patients with GH-related SHD were selected for this retrospective study in the Fifth Medical Center of Chinese PLA General Hospital from January 2017 to July 2022. The clinical manifestations, therapeutic responses, and effectiveness of MMI were evaluated. RESULTS: Systemic jaundice (100.0%), yellow urine (100.0%), fatigue (87.9%), and goiter (66.7%) were the main symptoms. Total bilirubin (TBIL) had no linear correlation with free triiodothyronine (FT3) (r = -0.023, p = .899), free thyroxine (FT4) (r = 0.111, p = .540), T3 (r = -0.144, p = .425), and T4 (r = 0.037, p = .837). On the 14th day after admission, FT3, FT4, T3, T4, TBIL, direct bilirubin (DBIL), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), γ-glutamyltransferase (GGT), and international normalized ratio (INR) decreased compared with the baseline (p < .05). The decrease rates of FT3, FT4, T3, T4, TBIL, and DBIL in the MMI group were higher than those in the non-MMI group (p < .05). The improvement rate of the MMI group (77.8%) was higher than that of the non-MMI group (9.5%, p = .001). MMI treatment is an independent predictor affecting the early improvement of patients (OR = 0.022, p = .010). CONCLUSIONS: The main clinical manifestations of patients with GH-related SHD were symptoms related to liver disease. Low-dose MMI was safe and effective for them.

Association of clinical manifestations of secondary lymphedema and lymph node dissection sites in the lower extremities of patients with melanoma.

BACKGROUND: Lymphedema is a chronic, debilitating disease that often requires life-long management. Predicting clinical manifestations and prognosis is crucial in clinical practice because the treatment of lymphedema should be individualized for best clinical outcome. The aim of this study is to explore the location and severity of lymphedema secondary to inguinal and/or iliac lymph node dissection (LND) in patients with melanoma. METHODS: Patients with melanoma who received LND at a single tertiary medical center between 1 January 2010 and 31 September 2022 were retrospectively reviewed. Patient who received inguinal LND only were designate as the inguinal group while those who received both ilioinguinal LND were included in the ilioinguinal group. Volumetric measurement was used to objectify the severity and location of lymphedema. Clinical data was acquired for 12-15 months of follow-up. RESULTS: Among 81 patients, 43 (53%) had developed lymphedema in the lower extremities at an average of 33 days after the surgery. Initially, patients manifested with medial thigh lymphedema in the inguinal group while patients were presented with whole leg lymphedema in the ilioinguinal group. Lower leg volume of the ilioinguinal group was significantly higher than the inguinal group. After more than 12 months of lymphedema treatment, upper leg volume was higher in the ilioinguinal group than the inguinal group (12.7% vs 5.4%, p < 0.05). CONCLUSION: Lymphedema developed in early post-op period. The ilioinguinal group presented with a larger volume of lymphedema in the distal area of the legs. Even after sufficient treatment, predominant lymphedema remained in the proximal leg for the ilioinguinal group. Patients with both inguinal and iliac LND were associated with more severe lymphedema. Based on the dissection sites, the clinical manifestations and prognosis of leg lymphedema can vary widely. Thus, clinicians should consider the dissection site when approaching melanoma patients with lymphedema.

The clinical manifestation and outcome of COVID-19 in patients with a history of ischemic heart disease; a retrospective case-control study.

INTRODUCTION: Coronary artery disease (CAD) is considered an independent risk factor for COVID-19. However, no study has specifically examined the clinical manifestations and outcomes of COVID-19 in patients with ischemic heart disease (IHD). METHODS: In a retrospective case-control study between 20 March 2020 to 20 May 2020, the medical record of 1611 patients with laboratory-confirmed SARS-CoV-2 infection was reviewed. IHD was defined as a history of an abnormal coronary angiography, coronary angioplasty, coronary artery bypass graft (CABG), or chronic stable angina. Demographic data, past medical history, drug history, symptoms, vital signs, laboratory findings, outcome, and death were investigated from medical records. RESULTS: 1518 Patients (882 men (58.1%)) with a mean age of 59.3 ± 15.5 years were included in the study. Patients with IHD (n = 300) were significantly less likely to have fever (OR: 0.170, 95% CI: 0.34-0.81, P < 0.001), and chills (OR: 0.74, 95% CI: 0.45-0.91, P < 0.001). Patients with IHD were 1.57 times more likely to have hypoxia (83.3% vs. 76%, OR: 1.57, 95% CI: 1.13-2.19, P = 0.007). There was no significant difference in terms of WBC, platelets, lymphocytes, LDH, AST, ALT, and CRP between the two groups (P > 0.05). After adjusting for demographic characteristics, comorbidities and vital signs, the risk factors for mortality of these patients were older age (OR: 1.04 and 1.07) and cancer (OR: 1.03, and 1.11) in both groups. In addition, in the patients without IHD, diabetes mellitus (OR: 1.50), CKD (OR: 1.21) and chronic respiratory diseases (OR: 1.48) have increased the odds of mortality. In addition, the use of anticoagulants (OR: 2.77) and calcium channel blockers (OR: 2.00) has increased the odds of mortality in two groups. CONCLUSION: In comparison with non-IHD, the symptoms of SARS-CoV-2 infection such as fever, chills and diarrhea were less common among patients with a history of IHD. Also, older age, and comorbidities (including cancer, diabetes mellitus, CKD and chronic obstructive respiratory diseases) have been associated with a higher risk of mortality in patients with IHD. In addition, the use of anticoagulants and calcium channel blockers has increased the chance of death in two groups without and with IHD.

A case report and literature review on nephrogenic alveolar soft part sarcoma: clinicopathological manifestations and genetic features.

BACKGROUND: Alveolar soft part sarcoma (ASPS) is a rare kind of malignant soft tissue tumor with undefined differentiation, of which the incidence rate accounts for only 0.5-1.0% among all kinds of soft tissue tumors. An even rarer ASPS occurs in kidney. CASE PRESENTATION: Here we reported a case of a 7-year-old girl diagnosed with nephrogenic ASPS, regarding the analyses of the incidence, clinical manifestation, pathology and genetic diagnosis, in order to deepen the recognition of the disease. CONCLUSIONS: ASPS is very rare, and tends to occur to young patients. It is very significant to precisely diagnose ASPS at an early stage, which will be the key point for the following treatment choices and prognosis.

[Intrahepatic and extrahepatic clinical manifestations and treatment progress for hepatitis type E].

Hepatitis type E virus (HEV) is one of the main causes of acute hepatitis globally and has thus gained attention as a public health issue. The diverse clinical manifestations of hepatitis type E are typically acute and self-limiting with mild symptoms, but populations with underlying liver disease or immunocompromised patients can have severe and chronic symptoms. Severity and chronicity can arise and manifest as fulminant hepatitis, chronic hepatitis, or even hepatic failure. HEV infection-induced hepatic failure (acute-on-chronic liver failure), based on the different backgrounds of chronic liver disease, is a clinical phenotype of severe HEV infection that requires attention. In addition, HEV infection can exhibit extrahepatic clinical manifestations of multi-system and organ involvement like neurological diseases (Guillain-Barré syndrome), renal diseases (membranous/membranous proliferative glomerulonephritis, cryoglobulinemia), and blood diseases (thrombocytopenia). At home or abroad, there are no antiviral drugs approved, particularly for HE treatment. Since most acute HE can resolve spontaneously, no special treatment is required clinically. However, in patients with severe or chronic HE, ribavirin (RBV) monotherapy and/or pegylated interferon-combination therapy have achieved certain antiviral effects. Combined small-molecule drugs and RBV have been attempted to treat HEV, but high-level evidence-based treatment is still lacking. Thus, new, highly effective anti-HEV drugs are clinical priorities to address these concerns. Severe and chronic HEV infections' clinical phenotype, early detection, mechanism, intervention, and outcome need additional study.
