Background: The exploration of age-related clinical features and adverse outcomes of non-disabling ischemic cerebrovascular disease (NICE) has been largely unaddressed in current research. This study aimed to analyze the differences in clinical characteristics and prognostic outcomes of NICE across various age groups, utilizing data from the Xi'an Stroke Registry Study in China. Methods: The age distribution of NICE was categorized into four groups: age ≤ 54 years, age 55–64 years, age 65–74 years, and age ≥ 75 years. Multivariate Cox logistic regression analysis was employed to evaluate the 1-year risk of outcome events in each age group of patients with NICE. A subgroup analysis was conducted to explore interaction factors influencing age-dependent outcomes in patients with NICE. Results: This study included 1,121 patients with NICE aged between 23 and 96 years, with an average age of 63.7 ± 12.2 years. Patients aged ≥ 75 years had a higher proportion of women, lower education levels, and a greater likelihood of having urban employee medical insurance. Those aged < 55 years had a higher prevalence of smoking, while individuals aged > 65 years showed a higher prevalence of comorbidities. Furthermore, there was a significant decrease in body mass index among patients aged ≥ 75 years. Laboratory tests indicated well-controlled blood lipids, liver function, and inflammation across all age groups, but renal function was notably reduced in patients with NICE aged ≥ 75 years. Adjusting for potential confounding factors revealed a significant increase in the one-year risk of all-cause mortality and poor prognosis among patients aged ≥ 75 years compared to those aged < 55 years, with no significant gender difference observed. Subgroup analysis indicated that patients with NICE who consumed alcohol were more prone to experience all-cause mortality with advancing age. Conclusions: Age significantly influences the clinical characteristics and prognostic outcomes of NICE patients. Clinicians should consider age-specific characteristics when diagnosing, treating, and developing prevention strategies. Tailored prevention and treatment strategies for different age groups can enhance prognosis and reduce adverse outcomes in NICE patients. [ABSTRACT FROM AUTHOR]

Background: Hemorrhagic stroke, involving bleeding within the brain or surrounding areas, presents a distinct profile of socio-demographic and clinical characteristics. Hemorrhagic strokes are more common in older adults. However, younger individuals with certain risk factors can also be affected. This study aimed to find out the socio-economic characteristics of hemorrhagic stroke patients. Methods: This prospective observational study was conducted in the Medicine In-patients Department of Dhaka Medical College Hospital, Dhaka, Bangladesh, from October 2009 to March 2010. A total of 60 cases of hemorrhagic stroke were enrolled using a purposive sampling technique. Data analysis was performed using MS Office tools. Results: The mean age of participants was 50.33 ± 8.93 years, with a male-to-female ratio of 3:1. 13.3% were illiterate, 60% had a monthly family income of over 10,000 BDT. Family history of stroke was reported by 13.3%, 28.3% experienced symptoms during sleep, 20% during work, and 15% during excitement. 58.3% experienced a sudden onset of symptoms. Frequent comorbidities included hypertension (40.0%) and diabetes mellitus (30.0%). Headache was the most common symptom (66.7%). Neurological exams showed normal consciousness in 66.7%, with varying grades in the remainder. Normal speech was noted in 70.0%, normal muscle bulk in 91.7%, and hypertonic muscle tone in 80.0%. Among hemorrhagic stroke patients, 51.7% had right-sided intracerebral hemorrhage on CT. Conclusion: Older adults are particularly susceptible to hemorrhagic stroke. Most patients experience a sudden onset of symptoms, with headaches being the most common. Typically, patients retain normal consciousness, speech, muscle tone, and muscle bulk in the majority of cases. [ABSTRACT FROM AUTHOR]

Large-scale original research on ICI-induced SJS/TEN is limited. This study aimed to explore the unique clinical characteristics and potential pathophysiological mechanisms of SJS/TEN induced by ICIs.Methods: This cross-sectional study compared the clinical features of SJS/TEN induced by ICIs and non-ICIs, and reviewed the case characteristics of ICI-induced SJS/TEN. Clinical features were analyzed using independent t-tests, Mann–Whitney U-tests, and multivariable regression models.Results: This study enrolled 41 cases of ICI-induced SJS/TEN and 107 non-ICI-induced cases from January 22, 2015, to May 28, 2024. ICI-induced SJS/TEN patients exhibited a trend towards a longer latency period (β: 17, 95% CI: − 1.49 to 35.48), a smaller affected body surface area (BSA) (β: − 40.68, 95% CI: − 71.59 to − 9.77), and milder oral and ocular mucositis than non-ICI-induced cases. A literature review identified PD-1 inhibitors as the primary ICIs involved and systemic corticosteroids as the most frequent intervention. No statistically significant difference in mortality rate was observed between patients treated with systemic corticosteroids alone and those receiving combination therapies (P= 0.85). The mortality rate for ICI-induced SJS/TEN was 24.5%.Conclusion: This study offered the largest comparative analysis to date, highlighting the unique clinical features of ICI-induced SJS/TEN, including a smaller affected BSA, a prolonged latency period trend, and milder oral and ocular mucositis. We described the epidemiology, clinical presentation, and therapeutic strategies for ICI-induced SJS/TEN. These findings not only contribute to a deeper understanding of the complex immune-inflammatory pathways in severe immune-related cutaneous adverse events (ircAEs) but also may inform the development of more targeted and effective treatments.Keywords: comparative analysis, clinical characteristic, latency period, body surface area, treatment

Abstract This study aims to elucidate the clinical and molecular characteristics, treatment outcomes and prognostic factors of patients with histone H3 K27-mutant diffuse midline glioma. We retrospectively analyzed 93 patients with diffuse midline glioma (47 thalamus, 24 brainstem, 12 spinal cord and 10 other midline locations) treated at 24 affiliated hospitals in the Kansai Molecular Diagnosis Network for CNS Tumors. Considering the term “midline” areas, which had been confused in previous reports, we classified four midline locations based on previous reports and anatomical findings. Clinical and molecular characteristics of the study cohort included: age 4–78 years, female sex (41%), lower-grade histology (56%), preoperative Karnofsky performance status (KPS) scores ≥ 80 (49%), resection (36%), adjuvant radiation plus chemotherapy (83%), temozolomide therapy (76%), bevacizumab therapy (42%), HIST1H3B p.K27M mutation (2%), TERT promoter mutation (3%), MGMT promoter methylation (9%), BRAF p.V600E mutation (1%), FGFR1 mutation (14%) and EGFR mutation (3%). Median progression-free and overall survival time was 9.9 ± 1.0 (7.9–11.9, 95% CI) and 16.6 ± 1.4 (13.9–19.3, 95% CI) months, respectively. Female sex, preoperative KPS score ≥ 80, adjuvant radiation + temozolomide and radiation ≥ 50 Gy were associated with favorable prognosis. Female sex and preoperative KPS score ≥ 80 were identified as independent good prognostic factors. This study demonstrated the current state of clinical practice for patients with diffuse midline glioma and molecular analyses of diffuse midline glioma in real-world settings. Further investigation in a larger population would contribute to better understanding of the pathology of diffuse midline glioma.

Abstract Background Lipodystrophy is characterized by progressive loss of adipose tissue and consequential metabolic abnormalities. With new treatments emerging for lipodystrophy, there is a growing need to understand the prevalence of specific comorbidities that may be commonly associated with lipodystrophy to contextualize the natural history of lipodystrophy without any disease modifying therapy. Objective To examine the risk of specific clinical characteristics in people living with lipodystrophy (LD) in 2018–2019 compared with the general US population, among the commercially insured US population. Methods A retrospective cohort study was conducted using the 2018–2019 Clinformatics® Data Mart database. An adult LD cohort (age ≥ 18 years) with at least ≥ 1 inpatient or ≥ 2 outpatient LD diagnoses was created. The LD cohort included non-HIV-associated LD (non-HIV-LD) and HIV-associated LD (HIV-LD) subgroups and compared against age- and sex-matched control groups with a 1:4 ratio from the general population with neither an LD or an HIV diagnosis using odds ratios (ORs) with 95% confidence intervals. Results We identified 546 individuals with non-HIV-LD (mean age, 60.3 ± 14.9 years; female, 67.6%) and 334 individuals with HIV-LD (mean age, 59.2 ± 8.3 years; female, 15.0%) in 2018–2019. Compared with the general population, individuals with non-HIV-LD had higher risks (odds ratio [95% confidence interval]) for hyperlipidemia (3.32 [2.71–4.09]), hypertension (3.58 [2.89–4.44]), diabetes mellitus (4.72 [3.85–5.79]), kidney disease (2.78 [2.19–3.53]), liver fibrosis or cirrhosis (4.06 [1.66–9.95]), cancer (2.20 [1.59–3.01]), and serious infections resulting in hospitalization (3.00 [2.19–4.10]). Compared with individuals with HIV, those with HIV-LD have higher odds of hypertension (1.47 [1.13–1.92]), hyperlipidemia (2.46 [1.86–3.28]), and diabetes (1.37 [1.04–1.79]). Conclusions LD imposes a substantial burden on affected individuals due to a high prevalence of metabolic comorbidities and other complications as compared with the general non-LD population. Future longitudinal follow-up studies investigating the causality between LD and observed comorbidities are warranted.

Abstract Background Burns cause serious physical and psychological harm to patients, placing a heavy burden on the global healthcare system. Our previous study detailed the epidemiological characteristics of burn injuries in Chinese inpatients from 2009 to 2018. Interestingly, the anatomic locations of burn injuries vary by gender, age, provinces, and outcomes among different causes. Therefore, this current study aims to analyze the characteristics of burn injuries in inpatients with various burn sites by collecting data in China from 2009 to 2018. This analysis will inform future healthcare system decisions and provide effective strategies. Methods Burns inpatients from 196 hospitals across 31 provinces in China were included in the study, covering the period from 2009 to 2018. The data collected encompassed information on gender, age, etiology, regions, clinical outcomes, and anatomical locations of the injuries. Data analysis was conducted using Microsoft Excel 2007. Results From 2009 to 2018, a total of 333,995 burns inpatients were recorded. The most vulnerable parts to burns were multiple burn sites (230,090, 68.89%). Women were more susceptible to lower limb burns (15,608, 14%), while men were more prone to eye injuries (8,387, 3.37%) and hand burns (6,119, 2.75%). The age group of 0–10 years was the most vulnerable to burns across all body areas, including internal organs. In China, individuals aged 20–50 years were at a higher risk of head and neck burns compared to other age groups. The Han population showed increased vulnerability to eye injuries (2.12 times higher than minorities), respiratory tract issues (2.09 times higher than minorities), and trunk burns (1.83 times higher than minorities), while being less susceptible to internal organ injuries (0.23 times fewer than minorities) and lower limb burns (0.78 times fewer than minorities). The southwest region had the highest proportion of burns inpatients with burns affecting single body parts, whereas the eastern area had the highest rates of respiratory tract burns (0.85%) and multiple burn sites (80.64%). Scalding was identified as the most common cause of burns, while flame burns (769, 55.81%) and chemical burns (438, 47.35%) were the main causes of respiratory tract and internal organ injuries, respectively. Conclusions This study provides an initial description of characteristics of burns inpatients with various anatomic locations of burns in China over the past decade. Our findings will contribute to the most up-to-date clinical evidence database for healthcare planning and prevention initiatives in both China and other countries.

Objective To investigate the clinical characteristics of patients with myocardial infarction with nonobstructive coronary arteries (MINOCA) in different ECG manifestations. Methods We selected 361 patients diagnosed with MINOCA from those with acute myocardial infarction undergoing coronary angiography. According to ECG manifestations of ST-segment elevation myocardial infarction (STEMI ) or non-ST-segment elevation myocardial infarction (NSTEMI), they were divided into STEMI group (n = 84) and NSTEMI group (n = 277). The general clinical data, laboratory examination results and coronary angiography results of the two groups were retrospectively analyzed. Results Compared with the STEMI group, the mean age of disease onset was greater in the NSTEMI group, while the proportion of females, and patients with hypertension and diabetes were all higher; the proportion of cases with smoking history was higher in the STEMI group, all with statistically significant differences (all P<0. 05). The white blood cell count, neutrophil count, and platelet count in the STEMI group were all higher than those in the NSTEMI group, and the differences were statistically significant (P < 0. 05). Platelet distribution width and left ventricular ejection fraction were higher in the NSTEMI group with statistically significant differences (P<0. 05). Plaque rupture, coronary spasm and thrombosis accounted for the majority of the disease causes in the STEMI group while the proportion of disease causes of oxygen supply imbalance and unknown etiology were higher in the NSTEMI group with statistically significant differences (P < 0. 05). Conclusion NSTEMI was the most common ECG change in MINOCA patients. Compared with MINOCA patients with ECG manifestations of STEMI, patients in the NSTEMI group had a greater age of disease onset, and more females are in the group, while these patients had a higher proportion of clinical risk factors, lower inflammatory and platelet indicators, and oxygen supply imbalance and unknown etiology account for higher proportion of disease causes.

Background We aimed to analyze the clinical characteristics of peripheral Epstein-Barr virus (EBV)-infected lymphocyte subtypes in children with chronic active EBV infection (CAEBV). Methods The levels of peripheral EBV infection of CD4+ T cells, CD8+ T cells, and CD56+ natural killer (NK) cells were determined by flow cytometry and quantitative polymerase chain reaction (qPCR) in patients with CAEBV from July 2017 to July 2022. Results In total, 112 children with CAEBV were evaluated. Of these, CD4+ type, CD8+ type, and CD56+ type were defined in 44, 21, and 47 patients, respectively. Patients with CD8+ T-cell type had a significantly higher frequency of rash, while hepatomegaly was more common in patients with CD4+ T-cell type. Generally, patients with CD8+ T-cell type had the lowest overall survival rate (P =.017). Patients treated with chemotherapy and hematopoietic stem cell transplantation (HSCT) had a better prognosis (P =.001). In multivariate analysis, rash, hemophagocytic lymphohistiocytosis, CD8+ T-cell type, and no decrease of plasma EBV-DNA after treatment were independent indicators of poor prognosis (P =.002,.024,.022, and.012, respectively). Conclusions In children with CAEBV, rash was more frequent in patients with CD8+ T-cell type, whereas patients with CD4+ T-cell type were more likely to develop hepatomegaly. Patients with CD8+ T-cell type had a poor prognosis despite receiving chemotherapy or further HSCT. [ABSTRACT FROM AUTHOR]

Objective To investigate the clinical characteristics and long-term prognosis of patients aged under 25 years with acute myocardial infarction(AMI). Methods We enrolled the patients aged under 25 years(young group)who were diagnosed with AMI at The First Affiliated Hospital of Xi'an Jiaotong University from February 2013 to July 2023. And the patients who were admitted to the hospital during the same period and aged 25-44 years with the same gender and the same infarct sites were selected as the control group(young and middle-aged group)(1:2). The clinical data of the two groups including comorbidities, high risk factors and biochemical indicators were collected and compared, and prognostic factors were analyzed. Results In this study, we enrolled a total of 84 AMI patients: 28 in the young group and 56 in the young and middle-aged group. The patients in young group had single-vessel disease(15/26, 57.7%)and no obvious culprit vessel(7/26, 26.9%); their white blood cell count and uric acid level were significantly higher than those of the young and middle-aged group. The median follow-up was 72.4(25.5, 110.2)months in this study. The results of univariate and multivariate Cox proportional hazards regression model analysis showed that the younger group(HR=7.925, 95% CI: 1.861-33.749, P=0.005), length of hospital stay(HR=1.183, 95% CI: 1.001-1.398, P=0.048), and complicated typical angina symptoms(HR=0.090, 95%CI: 0.015-0.544, P=0.009)were independent factors affecting the patients' overall surivival. Conclusion Compared to middle-aged and young AMI patients, the younger AMI ones have a worse prognosis. Young patients(under 25 years), length of hospital stay and atypical angina symptoms are the most important risk factors for patients with AMI. Therefore, early detection and identification of AMI in young patients is helpful for improving the patients' prognosis. [ABSTRACT FROM AUTHOR]

Objective To analyze the correlation between clinical characteristics and dosimetric factors for the patients receiving intensity-modulated radiotherapy after breast cancer surgery, and to provide reference for the formulation of postoperative radiotherapy plan. Methods The data of breast cancer patients who received postoperative radiotherapy in Tenth People's Hospital Affiliated to Tongji University from January 2020 to December 2021 were retrospectively analyzed. Clinical characteristics, ipsilateral lung volume (ILV), mean lung dose (MLD) and volumetric dosimetric parameters V5-V50 were collected to analyze the correlation with the radiation pneumonitis. Results 75 cases of 177 breast cancer patients developed radiation pneumonitis; among these cases, 93.3% were grade 1 and 6.7% were grade 2. Univariable analysis showed that double target therapy, internal mammary lymph node radiotherapy, MLD, V13, V15, V20, V25, V30, V35, V40, V45, and V50 were all associated with the occurrence of radiation pneumonitis (all P<0.05). Multivariable analysis showed that both V35 and V50 were independent risk factors for the occurrence of radiation pneumonitis (all P<0.05). The receiver operator characteristic curve showed that the sensitivity and specificity of predicting radiation pneumonitis with 20.27% of V35 as the cut-off value were 42.7% and 77.5%, respectively, with an AUC of 0.619. The sensitivity and specificity of predicting radiation pneumonitis with 3.155% of V50 as the cut-off value were 50.7% and 75.5%, respectively, with an AUC of 0.626. Conclusions Both V35 and V50 are independent risk factors for the occurrence of radiation pneumonitis, and minimizing the high -dose region V35 and V50 are of great significance in reducing the incidence of radiation pneumonitis.

Objective To explore the expression and clinical significance of autophagy related proteins Beclin-1, microtubule-associated protein 1 light chain 3(LC3) in placenta tissues of pregnant women with fetal growth restriction(FGR). Methods A total of 40 pregnant women undergoing delivery due to FGR and 40 pregnant women undergoing normal delivery in the Second Affiliated Hospital of Zhengzhou University were enrolled as FGR group and healthy group between August 2022 and August 2023. The general clinical data in the two groups were collected. The levels of Beclin-1 and LC3 mRNA in placenta tissues were detected by PCR, and expressions of Beclin-1 and LC3 proteins were detected by immunohistochemistry. The differences in positive of Beclin-1 and LC3 proteins among patients with different clinical data were analyzed. Results The placental thickness, placental mass and neonatal weight in FGR group were lower than those in healthy group(P＜0.05). The mRNA levels of Beclin-1 and LC3 in FGR group were higher than those in healthy group(P＜0.05) and positive expression rates of Beclin-1 and LC3 proteins were significantly higher than those in healthy group(P＜0.05). There was significant difference in positive expression profile of Beclin-1 and LC3 proteins among patients with different placental thickness, placental mass and neonatal weight(P＜0.05). Conclusions The positive expressions of autophagy genes(Beclin-1 and LC3) are related to FGR, and their specific expression levels are closely related to fetal growth and development.

ABSTRACTObjective: An association exists between immune checkpoint inhibitors and hemophagocytic lymphohistiocytosis (HLH). Therefore, the main objective of this study was to collect data on this rare but potentially life-threatening immune-related adverse reaction to identify the medications that cause it, the clinical characteristics, and effective treatments.Methods: Literature in English and Chinese on immune checkpoint inhibitors causing HLH published from August 2014 to March 2024 was analyzed. Immune checkpoint inhibitors, immunotherapy, anti-PD-1, PD-L1 inhibitors, HLH, hemophagocytic lymphohistiocytosis, hemophagocytic syndrome keywords were used to find the literature on China Knowledge Network, Wanfang, PubMed and Emabase Databases.Results and discussion: Twenty-four studies were included, with a total of 27 patients (18 males and 9 females) with a mean age of 58 years (range 26–86). The mean time to the onset of symptoms was 10.3 weeks (7 days–14 months). The main clinical characteristics were fever, cytopenia, splenomegaly, methemoglobinemia, hypofibrinogenemia, and bone marrow biopsy showed phagocytosis. Twenty-two patients improved after the treatment with steroids, cytokine blocking therapy and symptomatic treatment, four patients died, and one patient was not described.Conclusion: HLH should be not underestimated as a potentially serious adverse effect of immune checkpoint inhibitors since appropriate treatments may save the life of patients.

Objective: Anti-dipeptidyl-peptidase-like protein-6 (DPPX) encephalitis is a rare autoimmune encephalitis, and clinical and experimental information regarding this disease is limited. We conducted this study to comprehensively describe the clinical characteristics, ancillary test results, neuroimaging results, and treatment response in a group of Chinese patients with anti-DPPX encephalitis for better understanding this disease. Methods: We recruited 14 patients who tested positive for anti-DPPX antibodies in the serum and/or cerebrospinal fluid from 11 medical centers between March 2021 and June 2023. This retrospective study evaluated data on symptoms, autoantibody test, auxiliary examinations, treatments, and outcomes. Results: The average age at diagnosis was 45.93 ± 4.62 years (range: 11-72 years), and 9 of the 14 patients were males. The main symptoms included cognitive impairment (50.0%, 7/14), central nervous system hyperexcitability (42.9%, 6/14), gastrointestinal dysfunction (35.7%, 5/14), and psychiatric disorders (35.7%, 5/14). Notably, we discovered specific findings on 18F-fluorodeoxyglucose positronemission tomography (PET)/magnetic resonance imaging in two patients. Co-existing autoantibodies were identified in two patients. Parainfection was identified in four patients. One patient had other autoimmune diseases, and one had tumor. Eleven patients received immunotherapy and most patients improved at discharge. Surprisingly, three male patients but no female patients relapsed during the 6 months of follow-up. Conclusion: The development and outcome of anti-DPPX encephalitis are variable. Male patients were predominant in our cohort. The most common symptoms were the classical triad of prodromal gastrointestinal dysfunction, cognitive and mental disorders, and central nervous system hyperexcitability. Infections, immune dysregulation, and tumors may be important etiologies. Long-term monitoring of disease development should be done in male patients. Overall, our results highlight novel clinical characteristics of anti-DPPX encephalitis. [ABSTRACT FROM AUTHOR]

Purpose: To explore the influence of postoperative Hirschsprung-associated enterocolitis (post-HAEC) on long-term outcomes and to identify risk factors of post-HAEC. Methods: The medical records of 304 eligible patients diagnosed with Hirschsprung's disease (HSCR) were reviewed. We analyzed the clinical characteristics of post-HAEC and its influence on long-term outcomes. Furthermore, risk factors for early and recurrent HAEC were identified separately. Results: The overall incidence of post-HAEC was 29.9% (91/304). We categorized early HAEC as occurring within postoperative 3 months (n = 39) and recurrent HAEC as occurring ≥ 3 episodes within postoperative 6 months (n = 25). Patients with early HAEC were more likely to experience worse nutritional status, defecation function, and quality of life compared to those with late or no episodes (P < 0.05). Similarly, the adverse influences of recurrent HAEC on these outcomes were also significant (P < 0.05). The risk factors for early HAEC included preoperative undernutrition, long-segment HSCR, and postoperative Grade 3–4 complications within 30 days. For recurrent HAEC, risk factors were preoperative malnutrition, non-parental caregivers, long-segment HSCR, and postoperative Grade 3–4 complications within 30 days. Conclusion: Classification of post-HAEC based on the first episode time and frequency was necessary. The earlier or more frequent episodes of post-HAEC have detrimental influences on long-term outcomes. Furthermore, risk factors for early and recurrent HAEC were different. [ABSTRACT FROM AUTHOR]

Objective To explore the expression and clinical significance of autophagy related proteins Beclin-1, microtubule-associated protein 1 light chain 3(LC3) in placenta tissues of pregnant women with fetal growth restriction(FGR). Methods A total of 40 pregnant women undergoing delivery due to FGR and 40 pregnant women undergoing normal delivery in the Second Affiliated Hospital of Zhengzhou University were enrolled as FGR group and healthy group between August 2022 and August 2023. The general clinical data in the two groups were collected. The levels of Beclin-1 and LC3 mRNA in placenta tissues were detected by PCR, and expressions of Beclin-1 and LC3 proteins were detected by immunohistochemistry. The differences in positive of Beclin-1 and LC3 proteins among patients with different clinical data were analyzed. Results The placental thickness, placental mass and neonatal weight in FGR group were lower than those in healthy group(P＜0.05). The mRNA levels of Beclin-1 and LC3 in FGR group were higher than those in healthy group(P＜0.05) and positive expression rates of Beclin-1 and LC3 proteins were significantly higher than those in healthy group(P＜0.05). There was significant difference in positive expression profile of Beclin-1 and LC3 proteins among patients with different placental thickness, placental mass and neonatal weight(P＜0.05). Conclusions The positive expressions of autophagy genes(Beclin-1 and LC3) are related to FGR, and their specific expression levels are closely related to fetal growth and development.

Objective: Movement disorders (MDs) are common in anti-N-methyl-Daspartate receptor (NMDAR) encephalitis but are poorly studied. This study aimed to investigate the clinical characteristics of MDs and the clinical differences between patients with and without MDs in anti-NMDAR encephalitis. Methods: A retrospective study was conducted on patients with anti-NMDAR encephalitis who were first diagnosed and treated in the First People's Hospital of Yunnan Province from January 2017 to September 2022. According to the presence or absence of MDs, all patients were divided into two groups, and the clinical manifestations, auxiliary examinations, and prognosis of the two groups were compared. Patients in the MDs group were further subgrouped by different ages (<12 years, 12-17 years, and ≥ 18 years) and genders, and the prevalence of each MD was compared in different age and gender groups. Results: (1) In our study there were 64 patients, of whom 76.6% (49/64) presented with MDs; the median age of onset in patients with MDs was 21 (15,35) years and 65.3% (32/49) were female. The three most common MDs were orofacial dyskinesia (OFLD) (67.3%), dystonia (55.1%), and stereotypies (34.7%). Patients <12 years were more likely to experience chorea than patients in other age groups (p = 0.003). (2) Compared with the non-MDs group, patients in the MDs group showed higher rates of prodromal manifestations, autonomic dysfunction, consciousness disorders, as well as pulmonary infection and gastrointestinal dysfunction (all p < 0.05). Peripheral blood neutrophil to lymphocyte ratio (NLR) (p = 0.014), the proportion of cerebrospinal fluid (CSF) NMDAR antibody titers ≥1:32 (p = 0.047), ICU admission rate (p = 0.04), length of stay (p = 0.007), maximum mRS score in the course of disease (p = 0.001) and mRS score at discharge (p = 0.006) in the MDs group were significantly higher than the non-MDs group. Conclusion: MDs associated with anti-NMDAR encephalitis were predominantly hyperkinetic. Chorea occurred more commonly in patients aged <12 years. Patients with MDs were prone to autonomic dysfunction, consciousness disorders, pulmonary infection, and gastrointestinal dysfunction; they had more intense inflammation, more severe disease, and a poorer short-term prognosis.

Objectives: To elucidate the sex-specific differences in demographic features, clinical characteristics, and quality of life in Chinese patients with psoriatic arthritis (PsA). Methods: A total of 1,074 patients with PsA registered between December 2018 and June 2021 from the Chinese REgistry of Psoriatic ARthritis (CREPAR) cohort were selected. The baseline data on demographics, clinical characteristics, commonly used laboratory tests, comorbidities, and quality of life assessments were collected for this cross-sectional analysis. Results: A total of 1,074 patients were included in this study, 585 (54.47%) of them were male and 489 (45.53%) were female. The age at PsA onset in male patients was earlier than that in female patients (38.10 ± 12.79 vs 40.37 ± 13.41, p = 0.005). For clinical characteristics, male patients presented with higher rates of axial involvement (43.89% vs 37.74%, p = 0.044) and nail involvement (66.15% vs 58.08%, p = 0.006), while female patients presented with higher rates of peripheral arthritis (89.57% vs 83.93%, p = 0.007). For laboratory tests, men presented with a higher percentage of HLA-B27 positivity than women (24.65% vs 16.70%, p = 0.002) and had higher levels of CRP (median 9.70 vs 5.65, p < 0.001). Regarding disease assessment indices, male patients scored higher in PASI and BASFI (median 5.00 vs 3.00, p = 0.007 and 1.80 vs 1.40, p = 0.012, respectively). No sex difference was found in rates of achieving remission. Factors associated with disease remission were also analyzed in both sexes. Conclusion: Demographic and clinical characteristics tend to vary between male and female patients with PsA. Male patients reported more functional limitations in daily life. Key Points • The demographic and clinical features vary greatly between male and female patients with PsA. • Male patients reported more functional burden in daily life as measured by BASFI.

Objective To analyze the clinical features of patients with infected pancreatic necrosis (IPN) complicated with fungal infection so as to identify possible risk factors for death. Methods We analyzed the clinical data of patients with IPN admitted to Xuanwu Hospital Capital Medical University from January 1, 2017 to December 31, 2021. According to the results of pancreatic necrotic tissue and drainage fluid culture, the patients were divided into the group with fungal infection and the group without fungal infection. The baseline data, clinical features and outcomes of the two groups were compared, and the risk factors for death in patients with fungal infection were analyzed. Results We included a total of 214 patients in the study, of whom 49 patients in the fungal infection group had wider necrotic involvement, lower hematopoietic volume, and higher blood glucose at admission. Patients with fungal infection had a higher proportion of multidrug-resistant bacteria (MDRB), and hospital and ICU stay as well as parenteral nutrition duration were also longer. In the group of patients with fungal infection, the proportion of patients undergoing surgery did not increase (P>0.05), but the proportion of patients with perioperative organ failure and death was higher (P<0.05). Candida albicans (44.8%) was the most common fungus detected, followed by Candida parapsilosis (28.6%) and Candida tropicalis (8.2%) . Logistic regression analysis showed that MDRB infection (OR=1.37, 95% CI:1.02-1.83), fungemia (OR=1.53, 95% CI:1.06-2.23), hyperglycemia (OR=1.65, 95% CI:1.28-2.10), new organ failure (OR=1.65, 95% CI:1.19-2.29) and bleeding complications (OR=1.64, 95% CI:1.28-2.10) after surgery were risk factors for death in patients with fungal infection. Conclusion Fungal infection increases mortality in patients with IPN and the incidence of new organ failure after surgery. Attention to fungemia, MDRB infection, hyperglycemia, organ failure and postoperative bleeding can help reduce the risk of death. [ABSTRACT FROM AUTHOR]

Objective: Eosinophilic chronic rhinosinusitis (eCRS) is a refractory subtype of CRS. This study aimed to compare the differences in clinical features and peripheral blood indices between eCRS and non-eCRS Chinese patients and identify the predictive factors for eCRS. Methods: In this study, a total of 1352 patients with CRS were enrolled and divided into eCRS and non-eCRS groups based on the degree of eosinophilic infiltration in histopathology, and their demographic and clinical characteristics, as well as peripheral blood indices, were compared. Logistic regression analysis was used to identify the factors associated with eCRS, and the optimal cut-off values of predictors were determined using subject working curves. Results: As compared to those in the non-eCRS group patients, the proportion of males, age, proportion of smokers, peripheral blood eosinophil count, and erythrocyte count were significantly higher, while the peripheral blood neutrophil count, platelet count, neutrophil/lymphocyte count ratio (NLR), platelet/lymphocyte count ratio (PLR), and neutrophil × platelet/lymphocyte count ratio (SII index) were significantly lower in the eCRS group patients. Logistic regression analysis showed that age, peripheral blood neutrophil count, eosinophil count, and platelet count were independent predictors of eCRS, and eosinophil count > 2.05 × 108/L could be used as a diagnostic marker for eCRS with a sensitivity and specificity of 87.1% and 78.3%, respectively. Conclusions: There were significant differences in the clinical features of eCRS and non-eCRS patients. Peripheral blood eosinophil count could early and more accurately predict eCRS.

This article reports a single case of a patient with systemic lupus erythematosus (SLE) combined with pure red cell aplasia (PRCA), and reviews 51 additional cases of patients reported by domestic and overseas papers from 1974 to 2021. These 52 (51+1) cases were analyzed to summarize the epidemiological features, clinical features, laboratory inspections, treatments and prognosis of the patients. The results indicated that among all the 52 cases, cases of SLE combined with PRCA were mostly seen in Asian childbearing age women. The median ages of patients diagnosed with SLE and diagnosed with PRCA were 31.5 years and 36.0 years, respectively. The time interval between the initial diagnosis of SLE and subsequent diagnosis of PRCA was significantly longer than the interval for the initial diagnosis of PRCA, suggesting a delayed onset of SLE in these patients (P=0.042). Various clinical features of the 52 patients were reported, including mostly fatigue, joint pains, Raynaud phenomena and rashes, and SLE maybe combined with autoimmune hemolytic anemia (AIHA), thymoma, hypothyroidism and myasthenia gravis (MG). In these reported cases, laboratory indicators showed higher proportions of antinuclear antibody (ANA), anti double stranded DNA antibody (anti-dsDNA antibody), positive urinary protein and low complement levels. Among the 52 patients, 51 cases (98.08%) were treated with glucocorticoids, followed by blood transfusion, cyclosporin A, cyclophosphamide and high-dose intravenous immunoglobulin. Of the 50 patients whose prognoses were reported, 44 showed improvement, while 3 treatments were not effective and 3 resulted in death. This article aims to enhance the understanding of SLE combined with PRCA among doctors.

ObjectiveTo analyze the clinical and epidemiological characteristics of confirmed cases of human monkeypox infection in Changning District， Shanghai， and to explore their clinical and epidemiological characteristics.MethodsClinical data from 10 reported cases of monkeypox in individuals residing in Changning District or identified by local medical institutions between July 20 and September 30， 2023， were collected. Epidemiological case investigations were conducted， and throat swabs， anal swabs， and rash swabs were collected by the treating medical institutions. Real-time fluorescence quantitative PCR was used for monkeypox virus nucleic acid testing， and descriptive epidemiological analysis was applied to analyze the epidemiological characteristics of the cases.ResultsAll 10 confirmed cases of human monkeypox infection were all young males with an average age of 35.4 years， all of whom belonged to the men who have sex with men （MSM） population， with no occupational clustering. The primary clinical symptoms included fever， rash， enlarged inguinal lymph nodes， and muscle soreness. Nine cases presented with a rash， and seven cases experienced fever symptoms. Among the 10 cases， one experienced fever， rash， enlarged lymph nodes， and muscle soreness； two had fever， rash， and enlarged lymph nodes； two had fever， rash， and systemic soreness； two had only a rash； one had fever or rash； and one was asymptomatic. Among the nine cases with a rash， the rash was mainly localized to the genital or anal area， with fewer cases presenting rashes on the limbs or trunk simultaneously. All cases reported a history of non-exclusive MSM behavior within 21 days before the onset of the disease. The interval between the last suspected high-risk exposure and the onset of symptoms was 4 to 10 days， with an average interval of 6.9 days. The time from the onset of fever to the appearance of a rash was 0 to 5 days， with an average of 1.87 days.ConclusionThe main clinical manifestations of human infection with monkeypox are fever， rash， and enlarged inguinal lymph nodes. The MSM population is a high-risk group for monkeypox infection， and its source of infection may be associated with MSM exposure. Early-stage symptoms are mild， leading to potential underdiagnosis. Additionally， patients may conceal information during the investigation process， which increases the difficulty of epidemic prevention and control.

Abstract Objective To analyze the clinical characteristics and types of congenital heart defect (CHD) in mild congenital anorectal malformation (CARM), namely the rectoperineal and rectovestibular fistulas. Methods The retrospective study of 183 patients with mild CARM was conducted with assessments of demographic information, color Doppler echocardiography results, and follow-up data. We performed an analysis of the clinical characteristics of CHD, grouping them based on sex and type of mild CARM. Results Of the 183 patients, rectoperineal fistula occurred in 133 patients (72.7%), while the frequency of CHD was 79.8% (146/183). Ventricular septal defects (VSDs) occur more frequently in patients with rectoperineal fistula compared to those with rectovestibular fistula (1.5% vs. 10%), while the opposite trend was observed for patent ductus arteriosus (PDAs) (39.8% vs. 22.0%). Additionally, males presented higher frequency of PDA (42.7% vs. 26.4%) and self-healing (6 months: 87.2% vs. 42.6%; 12 months: 91.0% vs. 63.2%) than females. However, males had a lower rate of undergoing cardiac surgery (6.4% vs. 17.6%) and a younger median diagnosis age (1 day vs. 9 days). Conclusion Our study indicates that there is a necessity for meticulous cardiac assessment and follow-up in neonates diagnosed with mild CARM.

Abstract Background Serum tumor markers (STM), extensively used for the diagnosis, monitoring and prognostic assessment of tumors, can be increased in some non-malignant lung diseases. To date, there is a paucity of studies regarding the clinical characteristics of non-cystic fibrosis bronchiectasis patients with positive STMs. Objective To investigate the clinical characteristics and indicators of bronchiectasis with positive STMs. Methods The clinical data of 377 bronchiectasis patients was retrospectively collected from January 2017 to December 2019 from Beijing Chaoyang Hospital. Patients were divided into the STM negative group, the single STM positive group and the ≥2 STMs positive group according to the number of the positive STMs. The clinical characteristics are described and compared separately. The multivariate logistic regression analysis model was used to investigate the indicators regarding positive STMs. Results Patients in the ≥2 STMs positive group were older (P = 0.015), had higher mMRC scores (P

To explore the clinical manifestations, endoscopic findings, histopathological changes, treatment, and prognosis of eosinophilic gastrointestinal disease (EGID) in children, with the aim of enhancing awareness among pediatricians about this condition. Methods Data of 267 children with EGID were prospectively collected from January 2019 to July 2022 at Jiangxi Children's Hospital, Hunan Children's Hospital, and Henan Children's Hospital. The age of onset, symptoms, physical signs, laboratory examination results, endoscopic findings, histopathological changes, and treatment outcomes were observed. Results Among the 267 children with EGID, the majority had mild (164 cases, 61.4%) or moderate (96 cases, 35.6%) clinical severity. The disease occurred at any age, with a higher prevalence observed in school-age children (178 cases). The main symptoms in infants were vomiting and hematemesis, while in toddlers, vomiting and bloody stools were prominent. Abdominal pain and vomiting were the primary symptoms in preschool and school-age children. Nearly half (49.4%) of the affected children showed elevated platelet counts on hematological examination, but there was no significant difference in platelet counts among children with mild, moderate, and severe EGID (P>0.05). Endoscopic findings in EGID children did not reveal significant specificity, and histopathological examination showed no specific structural damage. Among them, 85.0% (227 cases) received acid suppression therapy, 34.5% (92 cases) practiced dietary avoidance, 20.9% (56 cases) received anti-allergic medication, and a small proportion (24 cases, 9.0%) were treated with prednisone. Clinical symptoms were relieved in all patients after treatment, but three cases with peptic ulcers experienced recurrence after drug discontinuation. Conclusions Mild and moderate EGID are more common in children, with no specific endoscopic findings. Dietary avoidance, acid suppression therapy, and anti-allergic medication are the main treatment methods. The prognosis of EGID is generally favorable in children. [ABSTRACT FROM AUTHOR]

The multivariate logistic regression analysis model was used to investigate the indicators regarding positive STMs. Results: Patients in the ≥2 STMs positive group were older (P = 0.015), had higher mMRC scores (P < 0.001) and developed higher fever (P = 0.027). Additionally, these patients also had lower Albumin/Globulin Ratio (A/G), albumin (ALB), prealbumin (PAB) (P < 0.001, P < 0.001, P < 0.001, respectively) and higher CRP, ESR and Fbg (P < 0.001, P < 0.001 and P < 0.001, respectively). Age (OR 1.022, 95%CI 1.003–1.042; P = 0.026) and the number of affected lobes (OR 1.443, 95%CI 1.233–1.690; P < 0.001) were independently associated with one and ≥ 2 positive STMs in bronchiectasis patients. Conclusion: The ≥2 positive STMs are associated with a higher inflammation status and severer radiologic manifestations in bronchiectasis patients. [ABSTRACT FROM AUTHOR]

Objectives: Studies on the prognosis and risk stratification of patients with acquired immune deficiency syndrome (AIDS) – related Burkitt lymphoma (AR-BL) are rare. We aim to construct a novel model to improve the risk assessment of these patients. Methods: We retrospectively analyzed the clinical data of 34 patients over the past 10 years and the factors associated with progression-free survival (PFS) and overall survival (OS) were evaluated in univariate and multivariate Cox models. Then, the novel model consisting of screened factors was compared with the existing models. Results: With a 37-month median follow-up, the overall 2-year PFS and OS rates were 40.50% and 36.18%, respectively. The OS of patients who received chemotherapy was better compared with those without chemotherapy (P =.0012). Treatment with an etoposide, prednisone, oncovin, cyclophosphamide, and hydroxydaunorubicin-based regimen was associated with longer OS and PFS compared with a cyclophosphamide, doxorubicin, vincristine, and prednisone-based regimen (OS, P =.0002; PFS, P =.0158). Chemotherapy (hazard ratio [ HR ] = 0.075; 95% confidence interval [CI], 0.009-0.614) and Eastern Cooperative Oncology Group Performance Status (ECOG PS) 2 to 4 (HR = 4.738; 95% CI, 1.178-19.061) were independent prognostic factors of OS in multivariate analysis and we established a novel prognostic risk stratification model named GZ8H model with chemotherapy and ECOG PS. Conclusion: GZ8H showed better stratification ability than the international prognostic index (IPI) or Burkitt lymphoma IPI (BL-IPI). Furthermore, the C-index of the nomogram used to predict OS was 0.884 in the entire cohort and the calibration curve showed excellent agreement between the predicted and actual results of OS. No human immunodeficiency virus-related factors were found to be associated with OS and PFS of AR-BL patients in our study. Overall, the clinical characteristics and outcomes in AR-BL were shown and prognostic factors for OS and PFS were identified in this study. [ABSTRACT FROM AUTHOR]

Objective To analyze the clinical characteristics of C-TI-RADS 3 thyroid nodules with a diameter greater than 2 cm and explore their correlation with gender, nodule ingredient, contralateral cancer presence, diffuse echo changes, TPOAB and TGAB. Methods A retrospective analysis was made on the clinical and pathological information of 94 patients with thyroid nodules who were admitted to our department from September 2022 to March 2023. All the patients underwent cytological and/or histopathological examinations. The proportions of TBS I category, benign tumors, low-risk tumors, and malignant tumors were calculated. The proportion of TBS type I, benign tumors, low-risk tumors, and malignant tumors was quantified. Subsequently, a comparative analysis was conducted among the benign, low-risk, and malignant groups in terms of clinical characteristics including gender distribution, nodule composition, contralateral cancer occurrence, diffuse echo changes presence, as well as TPOAB and TGAB levels.Results Seven cases in TBS I category were excluded. Among the remaining 87 cases with confirmed pathology results for nodules, there were 72 benign cases(38 cytology cases and 34 histology cases), 5 low-risk thyroid tumors(2 cytology cases and 3 histology cases), 10 malignant cases(8 PTC cases, 1 FTC case, and 1 MTC case). There was a significant difference in nodule ingredient(cystic/solid)between different pathological types(X²=10.369, P=0.006). However, no statistical significance was found in terms of gender, diffuse echo changes, contralateral cancer presence, TPOAB or TGAB(P>0.05). Further analysis showed that the proportion of solid component was higher in low-risk tumors than in benign nodules(X²=9.571, P=0.002). No statistical significance was found between malignant nodules and low-risk nodules(X²=2.143, P=0.143), or between malignant nodules and benign nodules(X²=2.165, P=0.141). Conclusion Although TI-RADS 3 nodules are generally considered as potentially benign according to various versions of thyroid imaging reporting and data system, malignant nodules still account for a certain proportion. Attention should be paid to thyroid nodules with a typical ultrasonic signs, such as cystic nodules, thyroid follicular tumors and medullary thyroid carcinoma. Ultrasound guided fine needle aspiration cytopathology is necessary for evaluating benign and malignant nodules. It is necessary to pay attention to unsatisfactory or undiagnosable specimens to improve the accuracy of diagnosis. [ABSTRACT FROM AUTHOR]

Breast cancer is a growing concern in Iraq, posing significant health challenges for Iraqi women. The objective of this study was to describe the demographic and clinical characteristics associated with breast cancer among Iraqi women, with a specific focus on age-related differences. Medical records of 500 female patients diagnosed with breast cancer between 2017 and 2022 were retrospectively analyzed. Demographic information, clinical history, presentation details, treatment modalities, and outcomes were collected and analyzed. Among the studied cohort, 62.4% of breast cancer cases were diagnosed in women aged 50 and older. Marital status correlated significantly with age, with 89.9% of those diagnosed before 50 being married compared to 74.7% of those diagnosed after 50. Notably, 48% of patients diagnosed before 50 had breastfeeding duration of 1–3 months, contrasting with 28.5% of those diagnosed after 50. Diabetes mellitus, hypertension, hypercholesterolemia, heart disease, and vitamin D deficiency were significantly more prevalent among patients diagnosed after 50. Clinical presentation revealed 67.8% with tumor stage II. Metastasis to lymph nodes occurred in approximately 50% of patients. Among patients who were diagnosed after 50 years of age, 34% had metastasis, compared to 22.9% of those diagnosed before the age of 50. Mortality rates were higher in patients diagnosed after 50 (23%) compared to those under 50 (12.8%). The findings emphasize the need for targeted public health campaigns, early detection initiatives, and treatment optimization to improve patient outcomes and mitigate the burden of breast cancer.

Globally, gastrointestinal cancer is the most widespread neoplastic disease and the primary contributor to cancer-associated fatalities. Gastrointestinal signet ring cell carcinoma (SRCC) exhibits unique distinguishing features in several aspects when compared to adenocarcinomas (ACs). The scarcity of signet ring cell carcinoma has resulted in a heightened significance of related clinical and molecular investigations. However, a comprehensive and systematic review of the clinical, molecular, therapeutic, and research aspects of this disease is currently absent. This review provides an overview of the latest developments in our understanding of the clinical and molecular features of gastrointestinal signet ring cell carcinoma (SRCC). Additionally, we have compiled a list of potential therapeutic targets or biomarkers, as well as an examination of the current treatment options and the possible mechanisms of formation.

Abstract Background Respiratory syncytial virus (RSV) infection in adults remains less recognized and understood, both socially and clinically, compared to influenza virus infection. This retrospective study aims to delineate and compare the clinical manifestations of adult RSV and influenza virus infections in the lower respiratory tract, thereby enhancing awareness of RSV lower respiratory tract infection and providing strategic insights for its prevention and treatment. Methods Clinical data from January 2019 to December 2020 were analyzed for 74 patients with RSV and 129 patients with influenza A/B virus lower respiratory tract infections who were admitted to respiratory or intensive care units. All patients had complete clinical data with positive IgM and negative IgG viral antibodies. Comparison parameters included onset timing, baseline data, clinical manifestations, supplementary examination results, treatment methods, and prognosis, while logistic regression was employed to ascertain the correlation of clinical features between the two patient groups. Results In comparison to the influenza group, the RSV group presented less frequently with fever at admission but exhibited a higher incidence of dyspnea and wheezing on pulmonary auscultation (P

Laboratory test indexes, department of admission, sex, age, intensive care unit (ICU) admission, surgical history, and central venous catheter placement were collected. Patients were divided into surviving and deceased groups based on outcomes at discharge. Mortality risk factors were identified by univariate and multivariable analyses.Results: Seventy-two of 141 patients survived. Patients were mainly from the ICU and the Departments of Hepatobiliary Surgery and Hematology. Overall, 312 microbial strains were detected: 119 gram-positive, 152 gram-negative, and 13 anaerobic bacteria and 28 fungi. Among the gram-positive bacteria, coagulase-negative staphylococci were most frequent (44/119, 37%), followed by enterococci (35/119, 29.4%). Among coagulase-negative staphylococci, methicillin-resistant coagulase-negative staphylococci incidence was 75% (33/44). Among gram-negative bacteria, Klebsiella pneumoniae was most common (45/152, 29.6%), followed by Escherichia coli (25/152, 16.4%) and Pseudomonas aeruginosa (13/152, 8.6%). Among K. pneumoniae, the incidence of carbapenem-resistant (CR) K. pneumoniae was 45.7% (21/45). On univariate analysis, mortality risk factors included increased white blood cells and C-reactive protein, decreased total protein and albumin, CR strains, ICU admission, central venous catheter, multiple organ failure, sepsis, shock, pulmonary diseases, respiratory failure, central nervous system diseases, cardiovascular diseases, hypoproteinemia, and electrolyte disturbances (P < 0.05). Multivariable analysis showed that ICU admission, shock, electrolyte disorders, and central nervous system diseases were independent mortality risk factors. The survival curve shows that the survival rate of patients with polymicrobial CR bloodstream infections was lower than that of patients with polymicrobial non-CR bloodstream infections (P=0.029).Conclusion: Patients with polymicrobial bloodstream infections are typically critically ill and harbor multidrug-resistant bacteria. Thus, to minimize mortality rate in critically ill patients, changes in infectious flora should be monitored, antibiotics selected reasonably, and invasive procedures reduced.Keywords: clinical characteristic, etiology, intensive care unit, polymicrobial bloodstream infections, risk factors

Objective: The Omicron BA.5.2 variant of SARS-CoV-2 has undergone several evolutionary adaptations, leading to multiple subvariants. Rapid and accurate characterization of these subvariants is essential for effective treatment, particularly in critically ill patients. This study leverages Next-Generation Sequencing (NGS) to elucidate the clinical and immunological features across different Omicron BA.5.2 subvariants. Methods: We enrolled 28 patients infected with the Omicron variant, hospitalized in Zhangjiajie People's Hospital, Hunan, China, between January 20, 2023, and March 31, 2023. Throat swabs were collected upon admission for NGS-based identification of Omicron subvariants. Clinical data, including qSOFA scores and key laboratory tests, were collated. A detailed analysis of lymphocyte subsets was conducted to ascertain the extent of immune cell damage and disease severity. Results: Patients were infected with various Omicron subvariants, including BA.5.2.48, BA.5.2.49, BA.5.2.6, BF.7.14, DY.1, DY.2, DY.3, and DY.4. Despite having 43 identical mutation sites, each subvariant exhibited unique marker mutations. Critically ill patients demonstrated significant depletion in total lymphocyte count, T cells, CD4, CD8, B cells, and NK cells (P < 0.05). However, there were no significant differences in clinical and immunological markers across the subvariants. Conclusion: This study reveals that critically ill patients infected with different Omicron BA.5.2 subvariants experience similar levels of cellular immune dysfunction and inflammatory response. Four mutations - ORF1a:K3353R, ORF1a: L3667F, ORF1b:S997P, S:T883I showed correlation with immunological responses although this conclusion suffers from the small sample size. Our findings underscore the utility of NGS in the comprehensive assessment of infectious diseases, contributing to more effective clinical decision-making. [ABSTRACT FROM AUTHOR]

Objective To investigate the clinical characteristics, pathological features, treatment regimen, and prognosis of children with lupus nephritis (LN) and thrombotic microangiopathy (TMA), as well as the treatment outcome of these children and the clinical and pathological differences between LN children with TMA and those without TMA. Methods A retrospective analysis was conducted on 12 children with LN and TMA (TMA group) who were admitted to the Department of Nephrology, Children's Hospital of Nanjing Medical University, from December 2010 to December 2021. Twenty-four LN children without TMA who underwent renal biopsy during the same period were included as the non-TMA group. The two groups were compared in terms of clinical manifestations, laboratory examination results, and pathological results. Results Among the 12 children with TMA, 8 (67%) had hypertension and 3 (25%) progressed to stage 5 chronic kidney disease. Compared with the non-TMA group, the TMA group had more severe tubulointerstitial damage, a higher Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score at onset, and higher cholesterol levels (P<0.05). There were no significant differences between the two groups in the percentage of crescent bodies and the levels of hemoglobin and platelets (P>0.05). Conclusions There is a higher proportion of individuals with hypertension among the children with LN and TMA, as well as more severe tubulointerstitial damage. These children have a higher SLEDAI score and a higher cholesterol level. [ABSTRACT FROM AUTHOR]

Introduction: The emergency of biologics and surgical techniques targeting the specific inflammatory endotype in chronic rhinosinusitis with nasal polyps (CRSwNP) asks for efficient identification of patients with different endotypes. Although mucosal IL-4, IL-5, IL-13, and IgE have been used to define type 2 (T2) inflammation, the optimal one remains unclear. In this study, we aimed to determine the optimal anchor for T2 inflammation and identify clinical characteristics and nasal secretion biomarkers predicting different endotypes in CRSwNP. Methods: Six mediators in sinonasal tissue and 36 mediators in nasal secretion samples were detected by the Bio-Plex suspension array system. Mucosal IFN-γ and IL-17A levels were used to define the T1 and T3 endotype, respectively. The efficacy of mucosal IL-4, IL-5, IL-13, and IgE to define the T2 endotype was compared. The power of clinical characteristics and nasal secretion biomarkers to predict the T1, T2, and T3 endotype was analyzed. Results: Among mucosal IL-4, IL-5, IL-13, and IgE, IL-13 was the best one to coincide with the expression of other T2 biomarkers. A combination of atopy, facial pain symptom score, ethmoid/maxillary computed tomography score ratio, and blood eosinophil percentage had a moderate predictive performance for T2 endotype (area under the receiver operating curve [AUC] = 0.815), comparable to that of nasal secretion IL-5 (AUC = 0.819). For the T3 endotype, nasal secretion IL-1Rα identified it with an AUC value of 0.756. No efficient marker for the T1 endotype was found. Conclusion: IL-13 is a primary anchor for the T2 endotype in CRSwNP. Clinical characteristics and nasal secretion biomarkers are helpful for identifying the T2 and T3 endotype of CRSwNP.

All patients had complete clinical data with positive IgM and negative IgG viral antibodies. Comparison parameters included onset timing, baseline data, clinical manifestations, supplementary examination results, treatment methods, and prognosis, while logistic regression was employed to ascertain the correlation of clinical features between the two patient groups. Results: In comparison to the influenza group, the RSV group presented less frequently with fever at admission but exhibited a higher incidence of dyspnea and wheezing on pulmonary auscultation (P < 0.01). RSV infection was more prevalent among patients with underlying diseases, particularly chronic obstructive pulmonary disease (COPD) and demonstrated a higher probability of co-infections, most notably with Mycoplasma (P < 0.01). The RSV group had significantly higher lymphocyte counts (P < 0.01) and exhibited more incidences of pleural thickening, pulmonary fibrosis, and emphysema (P < 0.05). The use of non-invasive mechanical ventilation was more common, and hospital stays were longer in the RSV group compared to the influenza group (P < 0.05). Logistic multivariate regression analysis further revealed that age and tachypnea incidence were significantly higher in the RSV group (P < 0.05). Conclusion: Compared to influenza virus infection, adults with COPD are more susceptible to RSV infection. Moreover, RSV infection elevates the risk of co-infection with Mycoplasma and may lead to conditions such as pleural thickening, pulmonary fibrosis, and emphysema. The requirement for non-invasive mechanical ventilation is higher in RSV-infected patients, who also tend to have longer hospital stays. Therefore, greater awareness and preventive strategies against RSV infection are imperative. [ABSTRACT FROM AUTHOR]

Forkhead Box P4 (FOXP4) is a transcription factor that promotes tumor formation and progression. However, studies on its roles in colorectal adenocarcinoma (CRAC) and cell proliferation regulation are few to date. This work investigates the expression of FOXP4 in CRAC, explores the characteristic of FOXP4 in different clinicopathological features, and analyzes its regulation of cell proliferation. The GEPIA database was used to predict the trend of FOXP4 expression in colon cancer and normal mucosa. Tumor tissue and normal paracancerous mucosal tissue were sampled from 64 cases diagnosed with CRAC and who were receiving radical surgery at Tianjin Hospital from January 2017 and December 2022. FOXP4 and proliferating cell nuclear antigen (PCNA) were detected by the immunohistochemistry EnVision method. The colon cancer cell lines SW480, HCT15, and SW620 and the normal colon cell line NCM460 were selected, and expression of FOXP4 was detected by the Western blot method. The siRNA-FOXP4 plasmid was synthesized and transfected with SW480 and HCT15 cell lines, respectively, to establish si-FOXP4 groups, and empty vector transfection group (NC-FOXP4) and blank control group (NC) was set up. The expression levels of FOXP4 and PCNA were detected by the Western blot method, while the cell proliferation activity was assessed using CCK-8. Normally distributed quantitative data were compared between two and more groups with ANOVA (SNK-based pairwise comparison), while intergroup enumeration data comparisons were performed through χ2 test and assessed through linear correlation analysis. GEPIA-based prediction shows a potential rise in FOXP4 expression in colon cancer. The rate of positive FOXP4 expression is significantly higher in CRAC tissue than in normal mucosa (p<0.05). The difference in FOXP4 is statistically significant in the comparison of maximum tumor diameter and depth of invasion in CRAC (p<0.05) but not in the comparison of gender, age, degree of differentiation, tumor focus, tumor embolism, and lymph node metastasis (p>0.05). The expression levels of FOXP4 and PCNA in CRAC are positively correlated (p<0.05). FOXP4 expression is significantly higher in cell lines SW480, HCT15, and SW620 than in cell line NCM460. The cell proliferation activity and PCNA expression are significantly lower in si-FOXP4 group than in NC-FOXP4 and NC groups for cell lines SW480 and HCT15. FOXP4 is highly expressed and has a proliferative effect on tumor cells in CRAC. [ABSTRACT FROM AUTHOR]

Background: To develop and validate a multivariable risk prediction model for ketosis‐prone type 2 diabetes mellitus (T2DM) based on clinical characteristics. Methods: A total of 964 participants newly diagnosed with T2DM were enrolled in the modeling and validation cohort. Baseline clinical data were collected and analyzed. Multivariable logistic regression analysis was performed to select independent risk factors, develop the prediction model, and construct the nomogram. The model's reliability and validity were checked using the receiver operating characteristic curve and the calibration curve. Results: A high morbidity of ketosis‐prone T2DM was observed (20.2%), who presented as lower age and fasting C‐peptide, and higher free fatty acids, glycated hemoglobin A1c and urinary protein. Based on these five independent influence factors, we developed a risk prediction model for ketosis‐prone T2DM and constructed the nomogram. Areas under the curve of the modeling and validation cohorts were 0.806 (95% confidence interval [CI]: 0.760–0.851) and 0.856 (95% CI: 0.803–0.908). The calibration curves that were both internally and externally checked indicated that the projected results were reasonably close to the actual values. Conclusions: Our study provided an effective clinical risk prediction model for ketosis‐prone T2DM, which could help for precise classification and management. [ABSTRACT FROM AUTHOR]

Small cell lung cancer (SCLC) is a malignant tumor with remarkable proliferative and invasive ability, which has very poor clinical prognosis due to lack of effective treatments. In recent years, researches on cells, animal models and tumor samples have promoted the identification of molecular subtypes of SCLC, discovered unique biological and clinical characteristics, and proposed potential specific therapeutic targets for different subtypes. This will encourage the development of more accurate therapeutic strategies towards SCLC, with a view to improving the prognosis of the patients. This article will review the current SCLC molecular subtypes, focus on the clinical characteristics and therapeutic strategies of different SCLC subtypes, and propose reasonable suggestions for the future treatment of SCLC.

Abstract Sarcopenia is a syndrome characterized by progressive loss of skeletal muscle mass, strength and function, which is one of the most important clinical features of cancer malnutrition, representing a poor prognostic indicator in oncology. Sarcopenia is commonly assessed by measuring the skeletal muscle index (SMI) of the third lumbar spine (L3) using computed tomography (CT). The primary aim of this meta‐analysis was to study the association between low SMI and comprehensive clinicopathological characteristics as well as prognosis in patients with ovarian cancer. Data were searched in PubMed, EMBASE and Cochrane databases from inception to 10 June 2022. Studies evaluating the prognostic effect of SMI on ovarian cancer survival or chemotherapy‐related side effects were included. The risk of bias and study quality were assessed via the Newcastle–Ottawa Scale (NOS). The search strategy yielded 1286 hits in all three databases combined. Thirteen studies were included for qualitative and quantitative analysis, comprising 1814 patients. Our meta‐analysis revealed the significant association between low SMI and progression‐free survival (PFS) [P = 0.02; hazard ratio (HR): 1.40, 95% confidence interval (CI): 1.06–1.85], as well as 5‐year overall survival (OS) [P = 0.02; odds ratio (OR): 1.35, 95% CI: 1.05–1.74]. Low SMI was also obviously associated with body mass index (BMI)

Objective: The spread of the novel SARS-Cov-2 variant Omicron created a challenging public health situation in a number of countries. In March 2022, Omicron emerged in Changchun, China, and the number of patients infected rapidly increased. The prevalence of Omicron infection symptoms differs from that of Delta, with more upper airway clinical symptoms apparent. This study aimed to investigate the clinical and upper airway characteristics of the Omicron variant. Materials and methods: In this retrospective study, we collected data from participants in Changchun who had tested positive for Omicron with quantitative polymerase chain reaction between 10 March and 30 May 2022 using telephone interviews. The questionnaire was designed by the research team based on the number of upper airway symptoms using the visual analogue scale. We also considered age, sex, vaccination status, general symptoms, and cure period. Results: A total of 3715 patients (2056 males and 1659 females) with mild COVID-19 from the Omicron variant were included. The patients had a mean age of 38.63 ( ± 13.97) years (range 2–86 years). The vaccine uptake rate was 91.33 % (8.66 %, 4.58 %, 65.33 %, and 21.43 % had received zero, one, two, and three doses, respectively). The incidence of upper airway symptoms, including throat and nasal symptoms, was 54.21 %. Throat symptoms were the most common during Omicron infection (49.12 %). Nasal symptoms were also common (20.08 %). The incidence of lower airway symptoms was 25.60 %, and gastrointestinal symptoms was 10.87 %. The incidence of general symptoms was 55.26 %. The cure period ranged from three to 37 days, with a mean of 10.24 ± 4.69 days. We compared the upper airway symptom severity for Omicron among different vaccination statuses and found no differences. Conclusions: The main clinical characteristics of the SARS-Cov-2 Omicron variant are upper airway symptoms and general symptoms. Fever remains the most common symptom, followed by mild dry cough. There was no association between Omicron infection and COVID-19 vaccines, and the vaccination status might have been ineffective against upper airway symptom severity by Omicron.
