Background Capsular warning syndrome (CWS) is a rare clinical syndrome, which is defined as a recurrent transient lacunar syndrome. The mechanism and clinical management of CWS remain unclear. The aim of the study was to discuss the clinical characteristics of CWS and evaluate the different outcome between rt-PA and no rt-PA therapy. Methods The present multicenter retrospective study involved three medical centers, and the clinical data were collected from patients with CWS between January 2013 and December 2018. The clinical characteristics of CWS were analyzed. Patients were divided into two groups: rt-PA and no rt-PA groups. The therapeutic effects and prognosis of these two groups were analyzed. A good prognosis was defined as 3-month modified Rankin Scale (mRS) ≤ 2. Results Our study included 72 patients, 27 patients were assigned to rt-PA group, 45 in no rt-PA group. Hypertension and dyslipidemia were the most common risk factors. The mean number of episodes before irreversible neurological impairment or the symptoms completely disappeared was five times (range: 3–11 times). A total of 58 (80.55%) patients had acute infarction lesions on the diffusion weighted imaging (DWI). The most common infarct location was the internal capsule (41,70.69%), followed by the thalamus and pons. The difference in therapeutic effects between the rt-PA, single and double antiplatelet groups was not statistically significant ( P  > 0.05). A good prognosis was observed in 61 (84.72%) patients after 3 months, in which 23 (23/27, 85.19%) patients were from the rt-PA group and 38 (38/45,84.44%) patients were from the no rt-PA group ( P  > 0.05). After 3 months of follow-up, two patients had recurrent ischemic stroke. Conclusion The most effective treatment of CWS remains unclear. Intravenous thrombolysis is safe for CWS patients. Regardless of the high frequency of infarction in CWS patients, more than 80% patients had a favorable functional prognosis.

This study aims to investigate the risk factors associated with blood-brain barrier(BBB) disruption in patients with myelin oligodendrocyte glycoprotein antibody associated disease(MOGAD). We collected clinical data from 95 patients diagnosed with MOGAD at the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from October 2018 to May 2024. Patients were classified into normal or damaged BBB groups based on cerebrospinal fluid (CSF) albumin/serum albumin (QAlb). Binary logistic regression analysis was used to evaluate the risk factors for BBB disruption in MOGAD patients. Our study revealed that in MOGAD patients with BBB damaged, there is a higher proportion of acute phase high EDSS scores, higher incidence of prodromal symptoms, and a higher rate of viral infections. Myelitis is the main clinical phenotype, with clinical manifestations primarily including limb weakness and bladder/bowel dysfunction. Laboratory tests showed higher levels of CSF protein, immunoglobulin (IgG), 24-hour intrathecal IgG synthesis rate, peripheral blood leukocytes, neutrophil percentage, NLR, anti-thyroglobulin antibodies(TGAbs), and fibrinogen levels, while free triiodothyronine (FT3) and lymphocyte percentage were lower. Multivariate regression analysis indicated that an increased neutrophil percentage is an independent risk factor for BBB damage in MOGAD patients (OR=1.068, 95% CI: 1.018-1.122, P=0.008). Neutrophil percentage is a readily available and widely used indicator reflecting the immune system's state and the body's inflammation level. The change in neutrophil percentage is independently associated with BBB damage in MOGAD patients. This finding helps provide more reference information for personalized treatment decisions and further research into the pathogenesis of MOGAD.

China is the region with a high global burden of rifampicin resistance/multidrug-resistant tuberculosis (RR/MDR-TB) and low HIV incidence. Our aim was to assess the clinical and demographic characteristics of RR/MDR-extrapulmonary tuberculosis (EPTB) from 2015 to 2019 to provide evidence for the prevention and control of the disease in high TB burden areas. We investigated the clinical and demographic data of all MDR/RR-EPTB cases in a TB specialized hospital from China and compared the cases with the MDR/RR-pulmonary tuberculosis (PTB) patients over the same period. Of the RR/MDR-TB patients enrolled, 15.4 were EPTB. The most common anatomical site was pleural/chest wall (25.9%). Compared with RR/MDR-PTB, females were more likely to be susceptible to RR/MDR-EPTB (OR 1.65, 95% CI 1.52-1.77); the risk of RR/MDR-EPTB for 25-44 years group increased (OR 1.61, 95% CI 1.52-1.77), and then decreased with the increasing age (OR 1.48, 95% CI 0.74-1.69 for 44-65 years group and OR 2.23, 95% CI 0.98-2.71 for ≥65 years group); more likely to be newly diagnosed ( < 0.01) and less likely to to combine with diabetes (P < 0.01), more dependent on GeneXpert MTB/RIF (Xpert, 90.9%) for diagnosis, with significantly higher rates of pre-XDR/XDR and significantly lower favorable treatment outcomes (both p < 0.01). There are clinical and demographic differences between RR/MDR-PTB and RR/MDR-PTB. Xper should be recommended at an early stage for suspected patients, and fluoroquinolones should be used cautiously for anti-infective therapy in this population.

BackgroundKeratoconus (KC) is a condition marked by thinning and protrusion of the cornea resulting in high myopia and irregular astigmatism. Knowledge of KC patients’ profiles and management approaches used can help to predict the needs of public hospitals to improve patient care.AimThis study aimed to describe the profiles and management of KC patients.SettingCapricorn district, Limpopo Province, South Africa.MethodsMedical records of 188 KC patients attending public hospitals of Capricorn District from January 2017 to December 2020 were reviewed. Data on patient profile and their management were collected and analysed.ResultsThe mean age of KC patients was 20.64 ± 6.82 years and the majority (56.9%) were males. Clinical findings were mean unaided visual acuity (UVA) of 0.19 ± 0.18, best corrected VA of 0.53 ± 0.24, spherical equivalence of -4.89 ± 9.17 dioptre (D), mean K of 57.37 ± 17 D and corneal astigmatism of -6.24 ± 4.27 D. A total of 54.5% of patients had severe KC. Bilateral KC was found in almost all patients (97.3%) and a mean K difference of 7.59 ± 6.08 D (p < 0.001) between the better and the worse eye. The study found no significant difference in KC severity by age (p = 0.451) and gender (p = 0.819). Patients fitted with scleral lenses had the highest VA improvement of 0.44 ± 0.17.ConclusionMost patients presented with bilateral and severe KC. Scleral lenses provided higher VA improvement than other methods.ContributionThe study aimed to present the clinical profile and management of keratoconic patients attending public sector facilities. Knowledge of the patterns of KC presentation may assist in the development of intervention strategies and guidelines for best practice in the management of KC, especially in public sector facilities.

Background： The emergency department （ED） has a pivotal influence on the management of acute heart failure （AHF）, but dataconcerning current ED management are scarce. This Beijing AHF Registry Study investigated the characteristics. ED management, and short- and long-term clinical outcomes of AHF. Methods： This prospective, multicenter, observational study consecutively enrolled 3335 AHF patients who visited 14 EDs in Beijing from January 1, 2011, to September 23, 2012. Baseline data on characteristics and management were collected in the EDs. Follow-up data on death and readmissions were collected until November 31, 2013, with a response rate of 92.80%. The data were reported as median （interquartile range） for the continuous variables, or as number （percentage） for the categorical variables. Results： The median age of the enrolled patients was 71 （58 79） years, and 46.84% wvere women. In patients with AHH coronary heart disease （43.27%） was the most common etiology, andmyocardium ischemia （30.22%） was the main precipitant. Most of the patients in the ED received intravenous treatments, including diuretics （79.28%） and vasodilators （74.90%）. Fewer patients in the ED received neurohormonal antagonists, and 25.94%, 31.12%, and 33.73% of patients received angiotensin converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, and spironolactone, respectively. The proportions of patients who were admitted, discharged, left against medical advice, and died were 55.53%, 33.58%, 7.08%, and 3.81%, respectively. All-cause mortalities at 30 days and 1 year were 15.30% and 32.27%, respectively. Conclusions： Substantial details on characteristics and ED management of AHF were investigated. The clinical outcomes of AHF patients were dismal. Thus, further investigations of ED-based therapeutic approaches for AHF are needed.

INTRODUCTION: Diabetes mellitus is common in primary care, yet little has been reported of its primary care prevalence or the clinical characteristics of patients with Type 2 diabetes mellitus (T2DM).AIM: To determine the prevalence of diabetes mellitus and clinical characteristics of diabetes patients in primary care in the Waikato region.METHODS: Primary care data were extracted from the electronic records of 15 general practices for patients aged >20 years with current diabetes mellitus at 20 June 2017. Diabetes mellitus was defined as having a glycated haemoglobin (HbA1c) of ≥50 mmol/mol (6.7%) or having being dispensed two or more anti-diabetic medications in the previous 12 months. Additional data collected included patients’ ethnicity, age, sex and years since diagnosis.RESULTS: The overall prevalence of diabetes mellitus was 5.7% and was higher for Māori (8.6%), Asian (7.0%) and Pacific peoples (9.1%) than Europeans (5.0%; all P < 0.001). For patients with T2DM for whom current diabetes annual review data were available (n = 2227) the mean body mass index (BMI) was 32.8 ± 0.2 kg/m2, but BMI was higher in Māori, younger patients, females and patients diagnosed <2 years previously (all P < 0.001). Similarly, HbA1c levels were highest in Māori and younger patients (both P < 0.001), with 40% of patients overall having a HbA1c of ≤53 mmol/mol (7.0%). Approximately 70% of all patients had at least one measure of hypertension (systolic ≥130 or diastolic ≥80 mmHg), or dyslipidaemia. More than 85% of patients had completed a recent retinal screen and foot check.DISCUSSION: We found that management of T2DM was suboptimal, with measures for many patients not meeting clinical targets. Support should be provided to improve weight and glycaemic management, particularly for Māori, females and younger patients.

Background： Talaromyces （Penicillium） marneffei （TIM） is an emerging dimorphic human pathogenic fungus that is endemic to Southeast Asia. TM mostly occurs as an opportunistic infection in patients with human immunodeficiency virus （HIV）. The objective of this study was to compare the clinical and laboratory parameters of patients with TM infections who were HIV-positive and HIV-negative and to assess therapies and outcomes. Methods： This was a retrospective analysis of 26 patients diagnosed with disseminated TM infection from September 2005 to April 2014 at Fujian Provincial Hospital, China. Results： Patients with TM infection tend to present with fever, weight loss, and anemia. The time from symptom onset to confirmed diagnosis was greater for HlV-negative patients （n 7; median： 60 days, range： 14-365 days） than for HIV-positive patients （n = 19; median： 30 days, range： 3-90 days, Mann-Whitney U= 31.50, P = 0.041）. HIV-negative patients were more likely to have dyspnea （57.1% vs. 5.3%, Z： = 8.86, P = 0.010）, low neutrophil count （Mann-Whitney U = 27.00, P = 0.029）, high CD4 count （Mann-Whitney U= 0.00, P 0.009）, and high lymphocyte count （Mann-Whitney U = 21.00, P = 0.009）. There were no significant differences in other demographic, clinical, or biochemical characteristics. Among all the patients, 12 HIV-positive patient and 1 HlV-negative patient received amphotericin and fluconazole treatment, 9 of whom improved, l died, 2 had kidney damage, 1 had hypokalemia due to exceeded doses. Conclusions： HIV-negative patients with TM infections tend to have a longer diagnostic interval, a higher percentage of dyspnea, higher levels of CD4 and lymphocytes, and lower neutrophil counts than TM infection in HIV-positive patients. Treatment programs with amphotericin and fluconazole are mostly effective.

Background To comprehensively elucidate the genomic and mutational features of lung cancer cases, and lung adenocarcinoma (LUAD), it is imperative to conduct ongoing investigations into the genomic landscape. In this study, we aim to analyze the somatic mutation profile and assessed the significance of these informative genes utilizing a retrospective LUAD cohort. Methods A total of 247 Chinese samples were analyzed to exhibit the tumor somatic genomic alterations in patients with LUAD. The Cox regression analysis was employed to identify prognosis‐related genes and establish a predictive model for stratifying patients with LUAD. Results In the Dianjiang People's Hospital (DPH) cohort, the top five frequent mutated genes were (Epidermal growth factor receptor) EGFR (68%), TP53 (30%), RBM10 (13%), LRP1B (9%), and KRAS (9%). Of which, EGFR is a mostly altered driver gene, and most mutation sites are located in tyrosine kinase regions. Oncogene pathway alteration and mutation signature analysis demonstrated the RTK‐RAS pathway alteration, and smoking was the main carcinogenic factor of the DPH cohort. Furthermore, we identified 34 driver genes in the DPH cohort, including EGFR (68%), TP53 (30.4%), RBM10 (12.6%), KRAS (8.5%), LRP1B (8.5%), and so on, and 45 Clinical Characteristic‐Related Genes (CCRGs) were found to closely related to the clinical high‐risk factors. We developed a Multiple Parameter Gene Mutation (MPGM) risk model by integrating critical genes and oncogenic pathway alterations in LUAD patients from the DPH cohort. Based on publicly available LUAD datasets, we identified five genes, including BRCA2, Anaplastic lymphoma kinase (ALK), BRAF, EGFR, and Platelet‐Derived Growth Factor Receptor Alpha (PDGFRA), according to the multivariable Cox regression analysis. The MPGM‐low group showed significantly better overall survival (OS) compared to the MPGM‐high group (p < 0.0001, area under the curve (AUC) = 0.754). The robust performance was validated in 55 LUAD patients from the DPH cohort and another LUAD dataset. Immune characteristics analysis revealed a higher proportion of primarily DCs and mononuclear cells in the MPGM‐low risk group, while the MPGM‐high risk group showed lower immune cells and higher tumor cell infiltration. Conclusion This study provides a comprehensive genomic landscape of Chinese LUAD patients and develops an MPGM risk model for LUAD prognosis stratification. Further follow‐up will be performed for the patients in the DPH cohort consistently to explore the resistance and prognosis genetic features.

To study the clinical, serological and histologic features of primary Sjögren's syndrome (pSS) patients with early (young ≤35 years) or late (old ≥65 years) onset and to explore the differential effect on lymphoma development. From a multicentre study population of 1997 consecutive pSS patients, those with early or late disease onset, were matched and compared with pSS control patients of middle age onset. Data driven analysis was applied to identify the independent variables associated with lymphoma in both age groups. Young pSS patients (19%, n = 379) had higher frequency of salivary gland enlargement (SGE, lymphadenopathy, Raynaud's phenomenon, autoantibodies, C4 hypocomplementemia, hypergammaglobulinemia, leukopenia, and lymphoma (10.3% vs. 5.7%, p = 0.030, OR = 1.91, 95% CI: 1.11-3.27), while old pSS patients (15%, n = 293) had more frequently dry mouth, interstitial lung disease, and lymphoma (6.8% vs. 2.1%, p = 0.011, OR = 3.40, 95% CI: 1.34-8.17) compared to their middle-aged pSS controls, respectively. In young pSS patients, cryoglobulinemia, C4 hypocomplementemia, lymphadenopathy, and SGE were identified as independent lymphoma associated factors, as opposed to old pSS patients in whom SGE, C4 hypocomplementemia and male gender were the independent lymphoma associated factors. Early onset pSS patients displayed two incidence peaks of lymphoma within 3 years of onset and after 10 years, while in late onset pSS patients, lymphoma occurred within the first 6 years. Patients with early and late disease onset constitute a significant proportion of pSS population with distinct clinical phenotypes. They possess a higher prevalence of lymphoma, with different predisposing factors and lymphoma distribution across time.

Background： Drug is all important cause of liver injury and accounts for up to 40% of instances offidminant hepatic failure. Drug-induced liver injury （DILl） is increasing while the diagnosis becomes more difficult. Though many drugs may cause DILl, Chinese herbal medicines have recently emerged as a major cause due to their extensive use in China. We aimed to provide drug safety information to patients and health carets by analyzing the clinical and pathological characteristics of the DILl and the associated drug types. Methods： A retrospective analysis was conducted in 287 patients diagnosed with DILl enrolled in our hospital from January 2011 to December 2015. The categories of causative drugs, clinical and pathological characteristics were reviewed. Results： Western medicines ranked as the top cause of DILl, accounting for 163 out of the 287 DILl patients （56.79%） in our study. Among the Western medicine, antituberculosis drugs were the highest cause （18.47%, 53 patients） of DILl. Antibiotics （18 patients, 6.27%） and antithyroid （18 patients, 6.27%） drugs also ranked among the major causes of DILl. Chinese herbal medicines are another major cause of DILl, accounting for 36.59% of cases （105 patients）. Most of the causative Chinese herbal medicines were those used to treat osteopathy, arthropathy, dermatosis, gastropathy, leukotrichia, alopecia, and gynecologic diseases. Hepatocellular hepatitis was prevalent in DILl, regardless of Chinese herbal medicine or Western medicine-induced DILI. Conclusions： Risks and the rational use of medicines should be made clear to reduce the occurrence of DILl. For patients with liver injury of unknown origin, liver tissue pathological examination is recommended for further diagnosis.
