Extramedullary infiltration in pediatric acute myeloid leukemia: Results from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) initiative.

BACKGROUND: The outcome of extramedullary infiltration (EMI) in pediatric acute myeloid leukemia (AML) is controversial, and little is known about the implications of stem cell transplantation (SCT) and gemtuzumab ozogamicin (GO) treatment on patients with EMI. METHODS: We retrieved the clinical data of 713 pediatric patients with AML from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) dataset, and analyzed the clinical and prognostic characteristics of patients with EMI at diagnosis and relapse. RESULTS: A total of 123 patients were identified to have EMI at diagnosis and 64 presented with EMI at relapse. The presence of EMI was associated with age ≤2 years, M5 morphology, abnormal karyotype, and KMT2A rearrangements. Hyperleukocytosis and complex karyotype were more prevalent in patients with EMI at relapse. Additionally, patients with EMI at diagnosis had a reduced incidence of FLT3 ITD-/NPM1+, whereas those with EMI at relapse displayed a lower frequency of FLT3 ITD+. Patients with EMI at diagnosis exhibited a lower complete remission (CR) rate at the end of Induction Course 1 and higher relapse incidence. Importantly, EMI at diagnosis independently predicted both shorter event-free survival (EFS) and overall survival (OS). Regarding relapse patients, the occurrence of EMI at relapse showed no impact on OS. However, relapse patients with myeloid sarcoma (MS)/no central nervous system (CNS) exhibited poorer OS compared to those with CNS/no MS. Furthermore, regarding patients with EMI at diagnosis, SCT failed to improve the survival, whereas GO treatment potentially enhanced OS. CONCLUSION: EMI at diagnosis is an independent adverse prognostic risk factor for pediatric AML, and GO treatment potentially improves survival for patients with EMI at diagnosis.

Trigeminal Neuralgia Triggering Recurrent Attacks of Migraine in a Chronic Migraineur: A Hidden Etiology Between the Lines.

A 25-year-old man with a medical record of migraines presented with progressively worsening episodes of dizziness and constant right-sided neck and facial pain, each lasting for hours over a month. The increased pain frequency and lack of response to abortive treatment were not typical of his migraines. Investigation for an alternate cause of the patient's symptoms with an MRI revealed evidence of trigeminal neuralgia (TN). Following TN treatment and complete resolution of symptoms, the diagnosis was confirmed. The atypical presentation of TN and the existence of migraine history and symptoms in this patient suggest a relationship between TN episodes triggering migraine. This case underscores the importance of considering atypical presentations in patients with a history of migraines and the potential interplay between TN and migraines in diagnosis and treatment.

Characteristics of patients with initial diagnosis of systemic lupus erythematosus in emergency department and their outcomes: a retrospective single-center study.

STUDY OBJECTIVE: This study aims to investigate the characteristics of patients with an initial diagnosis of systemic lupus erythematosus (SLE) in an emergency department (ED) and their outcomes. METHODS: A total of 147 SLE patients (119 females and 28 males, mean age 26 ± 19 years) who visited the ED of the Peking University People's Hospital between January 2017 and June 2022 were enrolled in the study. Data on demographic information, clinical characteristics, comorbidities, therapy, and outcomes were collected. RESULTS: Most patients visit ED because of symptoms related to SLE (74.8%, 110/147). The remaining 37 patients (25.2%) visited ED due to infection (43.2%, 16/37), gastrointestinal bleeding (10.8%, 4/37), coronary heart or cerebrovascular disease (18.9%, 7/37), macrophage activation syndrome or thrombotic microangiopathy (18.9%, 7/37), leukemia (5.4%, 2/37), and hepatic encephalopathy (2.7%, 1/37). Of the patients, 54.4% (80/147) were first diagnosed with SLE at the time of their ED visit. Thrombocytopenia events occurred significantly more frequently in this group of patients (OR 3.664, 95% CI 1.586-8.464, p = 0.002). Pulse steroid therapy was administered to 32.5% (26/80) of the patients with an initial diagnosis of SLE, and 26.3% (21/80) of these patients also received IVIG therapy during their ED visit. SLEDAI scores were significantly decreased after 6 months of therapy. The rate of mortality was 6.8% (10/147) in the 6-month follow-up period, and all the ten deaths happened in patients with disease-established SLE. The main causes of death were infections (two patients) and SLE flare (four patients). CONCLUSION: Understanding disease patterns can contribute to physicians providing accurate diagnosis and efficient care for SLE patients in ED. Key Points • Systemic lupus erythematosus, a complex autoimmune disorder, can have either a chronic or a relapsing and remitting disease course. The disease can involve acute events or severe comorbidities, and frequent visits to the emergency department (ED) are inevitable. • It is essential to better understand which comorbidities can lead to emergency department visits. Accurate clinical diagnosis and appropriate interventions from ED physicians can have a strong impact on the prognosis of the disease. • Hematologic compromise attributed to SLE flare is the most common reason for ED visits. Owing to aggressive treatments, the clinical outcomes in patients with initial diagnosis of SLE have improved notably. • Our study highlights that early recognition and appropriate management of SLE-related conditions and other comorbidity in ED are crucial.

Extent of glaucomatous damage on the first presentation.

AIM: The aim is to determine the magnitude of glaucomatous damage in the asymptomatic subjects identified with primary glaucoma for the first time and thus to evaluate the significance and efficacy of screening measures for glaucoma. MATERIALS AND METHODS: An observational retrospective cohort study of 100 asymptomatic patients of age more than 40 years, diagnosed with and under treatment for primary glaucoma was performed. Patients were categorized into having early, moderate, and severe glaucoma, according to standard automated perimetry (SAP) mean deviation (MD) in the worse eye (<-6, -6 to -12 and >-12 dB, respectively). Risk factors were correlated with the severity of glaucoma at presentation and statistically analyzed. RESULTS: About 32%, 33%, and 35% of patients were found to have early, moderate, and severe stages of glaucoma with average MD of -3.51 ±1.53, -8.65 ±1.64, -17.15 ± 5.13 on SAP, respectively. The association of risk factors such as age (P = 0.006) and glaucoma awareness (P = 0.044) with the severity of glaucoma was statistically significant. There was no direct statistical correlation found between gender, history of diabetes mellitus, family history of glaucoma, intraocular pressure, central corneal thickness, the angle width, and the severity of glaucoma in our study. CONCLUSION: Majority of cases with primary glaucoma show no symptoms until advanced irreversible stages. Early screening and proper treatment are the only ways to halt its progression. In spite of available facilities, 68% of patients in our study were found to have moderate-to-severe stages of glaucoma. This indicates that our screening measures should reach the masses at the primary level, with a focus on awareness programs.

Diagnostic Dilemma in a Case of Necrotizing Lymphadenitis With Macrophage Activation Syndrome.

Necrotizing lymphadenitis is a histological diagnosis that can arise from various conditions, including lupus lymphadenitis (LL), Kikuchi disease (KD), and infectious causes. Distinguishing between Kikuchi disease and lupus lymphadenitis can be challenging in clinical practice. In this report, we present the clinical scenario of a young female patient with lymphadenopathy and elucidate the process through which we ultimately arrived at a diagnosis of systemic lupus erythematosus (SLE) with macrophage activation syndrome. This case underscores the significance of recognizing Kikuchi disease as a condition that can mimic lupus and sheds light on the distinguishing features of necrotizing lymphadenitis, with a particular focus on Kikuchi disease and lupus lymphadenitis.

Gene Expression Pattern of ESPL1, PTTG1 and PTTG1IP Can Potentially Predict Response to TKI First-Line Treatment of Patients with Newly Diagnosed CML.

The achievement of major molecular response (MMR, BCR::ABL1 ≤ 0.1% IS) within the first year of treatment with tyrosine kinase inhibitors (TKI) is a milestone in the therapeutic management of patients with newly diagnosed chronic myeloid leukemia (CML). We analyzed the predictive value of gene expression levels of ESPL1/Separase, PTTG1/Securin and PTTG1IP/Securin interacting protein for MMR achievement within 12 months. Relative expression levels (normalized to GUSB) of ESPL1, PTTG1 and PTTG1IP in white blood cells of patients (responders n = 46, non-responders n = 51) at the time of diagnosis were comparatively analyzed by qRT-PCR. 3D scatter plot analysis combined with a distance analysis performed with respect to a commonly calculated centroid center resulted in a trend to larger distances for non-responders compared to the responder cohort (p = 0.0187). Logistic regression and analysis of maximum likelihood estimates revealed a positive correlation of distance (cut-off) with non-achieving MMR within 12 months (p = 0.0388, odds ratio 1.479, 95%CI: 1.020 to 2.143). Thus, 10% of the tested non-responders (cut-off ≥ 5.9) could have been predicted already at the time of diagnosis. Future scoring of ESPL1, PTTG1 and PTTG1IP transcript levels may be a helpful tool in risk stratification of CML patients before initiation of TKI first = line treatment.

A Challenging Diagnosis of Febrile Pancytopenia in a Patient With a History of Autoimmune Disease.

Pancytopenia is a hematologic condition characterized by a decrease in all three peripheral blood cell lines. There are many causes of pancytopenia, and the proper approach is required for accurate diagnosis. Brucellosis and systemic lupus erythematosus (SLE) are both diseases that can initially present as pancytopenia, both of which require a targeted workup to diagnose. Due to the immune system's complexity, many distinct diseases may have similar symptomatology. Furthermore, infections and rheumatological diseases can stimulate the same molecular pathways and trigger T and B cells. This creates a cross-reactivity between microbial peptides and self-peptides, allowing the spread of microbial-specific T cells that can also respond to self-peptides. Brucellosis has broad clinical manifestations, often mimicking many other diseases, such as rheumatoid arthritis, sarcoidosis, and SLE. In addition, brucellosis-induced autoantibody production has been described as a triggering factor for immunologic reactions, elevating rheumatological markers by a poorly understood mechanism. Finally, SLE is a well-known medical condition that can mimic several medical conditions, including brucellosis.  We present a case of a young patient who was admitted with febrile pancytopenia. The patient also had IgM antibodies positive for brucellosis and high immune markers for SLE. She was treated for both diseases, and afterward, in retrospect, it was confirmed that the patient did not have acute brucellosis.

Biomarker testing in patients diagnosed with advanced/metastatic medullary thyroid cancer in the USA.

Aim: To describe real-world testing patterns for RET in US patients with advanced/metastatic medullary thyroid cancer and determine consistency of real-world testing practices with national guidelines. Materials & methods: The authors performed a retrospective medical record analysis of patients with advanced/metastatic medullary thyroid cancer who initiated systemic therapy between 2013 and 2018. Seventy-five US-based oncologists collected the data using a customized electronic data collection form. Results: A total of 59.6% (121 of 203) of patients underwent testing for RET, and 37.2% (45 of 121) had a RET mutation, of which 55.6% were identified as RET mutation-positive before initial diagnosis. Overall, 90 (44.3%) patients were tested for biomarkers on or after initial diagnosis, with RET being the most tested (95.6%) biomarker. Conclusion: The authors' findings suggest an opportunity to improve testing rates in accordance with treatment guidelines.

Mutations in the RET gene are common in patients with medullary thyroid cancer (MTC). As RET mutations are involved in the development of MTC, several treatment guidelines recommend counseling patients and testing for mutations in the RET gene in all patients with MTC. However, limited data are available on RET testing patterns in the USA in this patient population. In this study, the authors determined testing patterns for RET in patients with advanced or metastatic MTC in the USA using real-world data and found that only 60% of patients were tested for RET (i.e., testing for presence of RET mutations was observed in less than two-thirds of all patients included in the study). These results demonstrate the need for improved testing for RET mutations in patients with MTC in alignment with the treatment guidelines in routine clinical practice in the USA.

Age at initial diagnosis and prognosis of breast cancer: a nationwide multicenter retrospective study in China.

Background: Several studies have indicated possible associations between age and the prognosis of breast cancer (BC), but limited data are available from hospital-based multicenter studies in China. This study aimed to explore the associations between age at initial diagnosis of BC and the risk of recurrence or metastasis among Chinese women with newly diagnosed advanced breast cancer (ABC) and provide treatment decision support for BC patients of different ages to medical workers. Methods: The medical records of patients newly diagnosed with ABC were obtained from 21 hospitals in seven geographic regions in China from 2012 to 2014. Patients' general information, clinicopathological features at first diagnosis, treatment information, and prognosis were retrospectively collected based on the self-designed case report form (CRF). Cox proportional hazards regression models were used to determine hazard ratios (HR) and 95% confidence intervals (CI) for the associations between age groups and the risk of recurrence and metastasis. Results: A total of 1,852 cases were included in the final analysis. Age at initial diagnosis was shown to be significantly related to hormone receptor status, human epidermal growth factor receptor 2 (HER2) status, molecular subtypes, and the number of lymph node metastasis (all P<0.05). Patients aged <35 years were more likely to have bone metastasis (45.6%). Patients aged ≥65 years had a lower percentage of receiving surgery (87.1%), adjuvant chemotherapy (61.3%), adjuvant radiotherapy (35.5%), and adjuvant endocrine therapy (30.6%) than the other groups (all P<0.05). Compared with patients aged <35 years, the risk of recurrence or metastasis in those aged 55-64 years was significantly higher (HRage 55-64 =1.24, 95% CI: 1.04-1.47), and the risk of bone metastasis and lung metastasis in those aged 35-44 years was lower (HRbone metastasis =0.74, 95% CI: 0.59-0.93; HRlung metastasis =0.70, 95% CI: 0.53-0.93). After adjusting for stage, grade, and molecular subtype, surgery, neoadjuvant chemotherapy, adjuvant chemotherapy, adjuvant radiotherapy, adjuvant endocrine therapy, and family history of BC, patients aged 35-44 years still had a significantly reduced risk of bone metastasis and lung metastasis by 31% and 52%, respectively (HRbone metastasis =0.69, 95% CI: 0.48-0.98; HRlung metastasis =0.48, 95% CI: 0.31-0.74). Conclusions: Age at initial diagnosis is related to the clinicopathological characteristics and treatment pattern. Although the risk of site-specific metastasis varies by age, age is not an independent factor influencing the risk of total recurrence and metastasis. In accordance with current clinical practice guidelines for BC, however, precise treatment shall be chosen personally for patients whose ages at initial diagnosis are different.

[Time to initial diagnosis of imported malaria and its influencing factors in Jiangsu Province].

OBJECTIVE: To investigate the health-seeking behaviors of imported malaria cases after returning to China, and to investigate the factors affecting the time to initial diagnosis, so as to provide the scientific evidence for early identification of imported malaria cases and prevention of severe cases development and secondary transmission. METHODS: The individual demographic features, and the disease onset and the time to initial diagnosis of imported malaria cases in Jiangsu Province in 2019 were captured from the National Notifiable Disease Report System and the Information Management System for Parasitic Disease Control in China. The characteristics of health-seeking behaviors and epidemiological features of imported malaria cases were descriptively analyzed, and the factors affecting the time to initial diagnosis of imported malaria cases after returning to China were identified using multivariate logistic regression analysis. RESULTS: A total of 244 imported malaria cases were reported in Jiangsu Province in 2019, and the time to initial diagnosis of the cases were 1-12 days, with mean time of (1.53 ± 1.65) days, with median time of one day. The highest number of malaria cases seeking healthcare services were found on the day of developing primary symptoms (76 cases, 31.1%), followed by on the second day (68 cases, 27.9%), on the third day (46 cases, 18.9%), and 54 cases (22.1%) received initial diagnosis 3 days following presence of primary symptoms, including 3 cases with initial diagnosis at more than one week. High proportions of imported malaria cases with a delay in the time to initial diagnosis were seen in migrant workers who returned to China in January (14 cases, 5.7%) and December (13 cases, 5.3%) and those aged between 41 and 50 years (32 cases, 13.1%). Multivariate logistic regression analysis showed relative short time to initial diagnosis among imported malaria cases returning to China on March [odds ratio (OR) = 0.16, P = 0.03, 95% confidence interval (CI): (0.03, 0.85)] and those with a history of overseas malaria parasite infections [OR = 0.36, P = 0.001, 95% CI: (0.19, 0.67)]. CONCLUSIONS: Timely health-seeking behaviors should be improved among imported malaria cases in Jiangsu Province, patients with a history of overseas malaria infections require faster health-seeking activities.

Quality of life and related demographic factors in long-term survivors of childhood non-Hodgkin's lymphoma. / å„¿ç«¥éžéœå¥‡é‡‘æ·‹å·´ç˜¤é•¿æœŸç”Ÿå­˜è€ ç”Ÿæ´»è´¨é‡åŠç›¸å ³äººå£å­¦å› ç´ ç ”ç©¶.

OBJECTIVES: To evaluate the quality of life and related demographic factors in long-term survivors of childhood non-Hodgkin's lymphoma (NHL). METHODS: A retrospective analysis was performed on the medical and demographic data of the NHL patients who received treatment in the Sun Yat-sen University Cancer Center and achieved long-term survival at follow-up, with an age of <18 years at initial diagnosis and a present age of ≥18 years. A questionnaire survey was performed using 36-Item Short-Form Health Survey (SF-36) and the symptom subscale of the Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (QLQ-C30). The health status of long-term survivors of NHL was evaluated by comparing the scores of various dimensions of the SF-36 scale of general adult population in the United States (American norm) and those of the SF-36 scale of general adult population in Hong Kong, China (Hong Kong norm). The correlation between the score of each dimension of the scale and demographic characteristics was evaluated. The symptoms of long-term NHL survivors were evaluated according to the score of QLQ-C30 scale. RESULTS: A total of 23 patients with NHL with complete follow-up data were enrolled. The pathological types included diffuse large B-cell lymphoma in 10 patients, Burkitt lymphoma in 4 patients, T-cell lymphoblastoma in 5 patients, B-cell lymphoblastoma in 3 patients, and natural killer/T cell lymphoma in 1 patient. All patients received the chemotherapy regimen containing anthracyclines and alkylating agents. The median present age was 26.2 years (range: 16.9-55.8 years), and the median age at initial diagnosis was 10.4 years (range: 2.4-17.6 years). Among the 23 patients, 6 were married and had children and 2 had chronic diseases. There was no significant difference between the long-term survivors and the US norm in role physical, general health, role-emotional, and mental health (P>0.05), while the long-term survivors had significantly better scores of the other dimensions than the US norm (P<0.05). Similar results were obtained for the comparison between the long-term survivors and the China Hong Kong norm. Age at initial diagnosis was negatively correlated with the scores of social functioning, role physical, and general health in the SF-36 scale (P<0.05), and the present age of patients was positively correlated with the score of physical functioning and was negatively correlated with the score of general health (P<0.05). The urban and rural distribution of patients was related to the general health status (P<0.05). In addition, the long-term survivors of childhood NHL had relatively low scores of the symptom domain of QLQ-C30, and few moderate or severe symptoms were found. CONCLUSIONS: Long-term survivors of childhood NHL tend to have a good overall health status, with no significant differences compared with the general population. Age at initial diagnosis is the main demographic factor that affects patients' quality of life. Citation.

Hemodynamic Characteristics of Patients With Suspected Coronary Heart Disease at Their Initial Visit.

PURPOSE: It is difficult for doctors to decide whether patients with suspected coronary heart disease classified as Coronary Artery Disease Reporting and Data System (CAD-RADS) < 3 should be administered preventive treatment, or whether non-atherosclerotic chest pain should be considered. The aim of the current study was to investigate coronary hemodynamic characteristics in such patients, which may provide more information on their stenosis and be helpful for initial diagnoses. METHODS: Two patient-specific models were reconstructed based on the coronary computed tomographic angiography underwent in 2012. Patient 1 was classified as CAD-RADS 0, and was readmitted to hospital due to coronary artery disease within 5 years. Patient 2 was classified as CAD-RADS 2, and has experienced no adverse events to date. Computational fluid dynamics (CFD) analysis was used to obtain hemodynamic parameters including flow rate waveform, flow streamlines, time-average wall shear stress (TAWSS), and oscillatory shear index (OSI). RESULTS: Patient 1 exhibited no physiological characteristics of right coronary artery flow waveform, large areas of low TAWSS, and slow blood flow in the proximal and middle segments of the left anterior descending branch. Patient 2 exhibited reduced coronary supply, small and separate areas of abnormal TAWSS, and a higher left anterior descending branch OSI than patient 1. CONCLUSION: Hemodynamic abnormalities may play an important role in the prognosis of patients with coronary stenosis, and patient-specific hemodynamic characteristics may facilitate more accurate initial diagnosis, and better management. Overall hemodynamics (along the whole vessel) warranted attention at the time of the initial visit in patients classified as CAD-RADS < 3.

Cardiovascular characteristics of patients initially diagnosed breast cancer.

OBJECTIVE: We aimed to explore the cardiovascular characteristics of patients who were initially diagnosed with breast cancer. METHODS: A total of 600 patients who were diagnosed with primary breast cancer were included in this retrospective study. The data of fasting blood glucose, total cholesterol, total triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein (a) (LP (a)) and serum uric acid were collected. Univariate analysis was used to evaluate the cardiovascular risk factors (CVRFs) in patients with breast cancer. The arteriosclerotic cardiovascular disease (ASCVD) risk assessment was performed. Multivariate analysis was used to identify the factors that influenced axillary lymph node metastasis (ALNM). RESULTS: Compared with the premenopausal group, the prevalence of overweight/obesity (47.6% vs. 35.2%), diabetes (12.8% vs. 4.3%) and hypertension (49.7% vs. 26.3%) were significantly increased in the postmenopausal group (p < 0.05). Comparisons of rural patients and urban patients showed that there were significant differences in the diagnostic age (49.94 ± 9.92 vs. 52.59 ± 11.13) in the rural patients was notably younger in comparison with the urban patients (p < 0.05). However, the number of menopausal patients (44.3% vs. 53.3%) in the rural group were decreased in comparison with the urban group (p < 0.05). In ASCVD risk stratification, the proportion of low-risk patients (56.4% vs. 90.8%), medium-risk patients (20.6% vs 0.3%) and high-risk patients (19.3% vs. 6.6%) were significantly different between the postmenopausal group and premenopausal group (p < 0.05). Residence (OR 0.735; 95% CI 0.516-1.046; p = 0.087), the number of children (OR 1.250; 95% CI 0.990-1.578; p = 0.061) and LP (a) of ≥ 500 mg/L (OR 0.603; 95% CI 0.342-1.063; p = 0.080) were independent influencing factors of ALNM. CONCLUSION: Postmenopausal patients have more CVRFs and higher risks of ASCVD than premenopausal patients initially diagnosed with breast cancer. There was a correlation between CVRFs and ALNM in patients with breast cancer.

Agreement of Optic Nerve Head Evaluation of Primary Open-Angle Glaucoma Between General Ophthalmologists and Glaucoma Specialists.

PURPOSE: To investigate the agreement of optic nerve head evaluations and initial diagnoses of primary open-angle glaucoma (POAG) by general ophthalmologists and glaucoma specialists in Shanghai, China. METHODS: This multicenter, cross-sectional study involved the outpatients from the general ophthalmology departments of four top eye hospitals in Shanghai. The participants underwent ocular examinations, including intraocular pressure, fundus photography, corneal thickness, refractometry, visual acuity, visual field and gonioscopy. General ophthalmologists and glaucoma specialists performed the diagnoses and classified them as non-glaucoma, POAG suspects, and POAG. The consistency of initial diagnosis between general ophthalmologists and glaucoma specialists was measured using the weighted kappa coefficient. Logistic regression analysis was used to detect the risk factors for the reliability of POAG diagnosis. RESULTS: In 922 participants, the initial diagnosis rates of POAG and non-glaucoma were much higher in the glaucoma specialist group than in the general ophthalmologist group, while the initial diagnosis rates of POAG suspects were higher in the general ophthalmologist group. The weighted kappa coefficient between the two groups was 0.831±0.027 (95% confidence interval, 0.779-0.884). Logistic regression analysis of the risk factors for the reliability of POAG diagnosis showed that the independent risk factors were intraocular pressure (OR 8.363, 95% CI: 4.27-16.37) and vertical cup-to-disc ratio (OR 3.459, 95% CI: 1.54-7.76). CONCLUSION: The diagnosis consistency between the general ophthalmologists and the glaucoma specialists was similar among outpatients in the area of Shanghai. However, general ophthalmologists tended to classify the indefinite subjects as POAG suspects, and their accuracy in diagnosing POAG was low. By paying more attention to the risk factors of POAG diagnosis, general ophthalmologists could improve the diagnosis accuracy.

Comparison of survival outcomes between primary and secondary muscle-invasive bladder cancer: An updated meta-analysis.

Objective: Studies have showed that different follow-up starting points might potentially impact the comparison between primary (PMIBC) and secondary muscle-invasive bladder cancer (SMIBC), but the only previous meta-analysis did not differentiate the follow-up starting points of included studies. With more trials published, we aim to update the meta-analysis comparing PMIBC and SMIBC. Methods: PubMed, Embase, Cochrane Library and ClinicalTrial.gov. systematically searched. Literatures comparing the survival outcomes of PMIBC and SMIBC were selected. Outcomes of cancer-specific mortality (CSM), overall mortality (OM) and recurrence-free survival (RFS) were pooled and grouped based on the starting point of follow-up (after initial diagnosis or radical cystectomy (RC)). Newcastle-Ottawa Scale (NOS) and funnel plot were employed to assess the study quality and publication bias, respectively. Results: A total of 17 high-quality studies were selected, with 5558 patients aged from 59.8 to 72.7 (mean value) involved. The male-to-female ratio was roughly 4:1 (4390/1124). SMIBC had lower risk of CSM after initial diagnosis (HR 0.81, 95%CI 0.67-0.98, P=0.03, I2=70%), but higher risk of CSM after RC (HR 1.45, 95%CI 1.27-1.65, P<0.00001, I2=64%). In terms of OM and recurrence, outcomes were pooled only after RC, which both turned out to be higher for SMIBC (OM: HR 1.50, 95%CI 1.30-1.73, P<0.00001, I2=0%; Recurrence: HR 1.66, 95%CI 1.36-2.02, P<0.00001, I2=48%). No obvious publication bias was observed from funnel plot. Conclusion: The current study suggested SMIBC had higher risk of CSM, OM and recurrence after RC, but lower risk of CSM after initial diagnosis.

Impact of Healthcare Access Disparities on Initial Diagnosis of Breast Cancer in the Emergency Department.

Breast cancer continues to be the second leading cause of cancer deaths in women in the United States. This is more noticeable in communities with pronounced healthcare disparities. The aim of this study was to investigate the different demographics that might play a role in the detection of breast cancer in a county hospital emergency department (ED). A retrospective study was conducted of female patients diagnosed with breast cancer over a five-year period (1/1/2015 to 12/31/2018). Patients with breast cancer as the primary or secondary diagnosis were identified. This study shows that 66 (73.3%) women diagnosed in the ED were Hispanic or African American. There was a significant delay (a median of 461 days) in the time between the diagnosis of suspected breast cancer in the ED to their follow-up visit with definitive diagnosis in a primary care clinic. These findings suggest that women with a suspected breast cancer diagnosis who are seen in a safety net hospital and have Medicaid funding may have significant delays before final diagnosis is made. Patient demographics could have an impact on the patients' access to screening and regular healthcare visits, hindering an early breast cancer diagnosis by a primary care provider.

Study on the driving factors and forming mechanism of the willingness for primary doctors to make initial diagnosis / 中华医院管理杂志

Objective@#Based on the KAP and Prospect theory, to explore, construct and verify the theoretical model and formation mechanism of driving factors of primary care doctors′ willingness to carry out the primary diagnosis.@*Methods@#Using the random cluster sampling method, from April to May 2019, a questionnaire survey was conducted among doctors at 20 primary medical and health service institutions in Hangzhou. The survey covered the primary care doctors′ cognition level of primary diagnosis, their self-evaluation of primary medical care capabilities, evaluation of policies and systems, expectation of primary medical care, and their job satisfaction. Descriptive statistic, multiple linear regression and structural equation model were used to analyze and explore the driving factors and formation mechanism of their willingness to carry out the primary diagnosis.@*Results@#Primary care doctors′ willingness rate for primary diagnosis was 76.4%(308/403). Positive expectation(beta=0.309), cognition level(beta=0.216), evaluation of policies and systems(beta=0.184), and self-evaluation of primary diagnosis capability(beta=0.170), all of which directly affect the said willingness. The total effect of the five types of driving factors on the willingness of the primary diagnosis was as follows: cognitive level of the primary diagnosis(0.536), evaluation of the policy system(0.494), self-evaluation of the primary diagnosis capability(0.436), positive expectations of the primary diagnosis work(0.186), job satisfaction(0.146).@*Conclusions@#The cognition of the primary diagnosis, the capability of the primary diagnosis, the policy system and the positive expectation are the important premises, key driving forces, and a strong guarantee and motivation to drive primary care doctors to carry out the primary diagnosis. It is suggested that the government and medical institutions should further improve the cognition level of primary care doctors, focusing on systematically improving the service capability of primary care doctors′ primary consultation, coordinating to improve policy guidance measures such as financial input, medical insurance reimbursement and referral system, establishing and improving incentive measures such as career development, performance appraisal, salary and welfare of primary care doctors.

AML: high serum ferritin at initial diagnosis has a negative impact on long-term survival.

Increased serum ferritin (SF) is common in hematologic malignancies; however, its prognostic role in acute myeloid leukemia (AML) is not clearly established. We examined the impact of baseline SF on long-term survival in 137 intensively treated AML patients. Patients and baseline characteristics were retrieved from an AML database at Charité University Medical Center Berlin, Campus Virchow Clinic. After c-reactive protein (CRP)-based adjustment for inflammation, patients were grouped according to their baseline SF level. Survival analysis was performed accordingly. A significant decline in overall survival and relapse-free survival was observed in patients with high SF as compared to those with low SF. Furthermore, elevated baseline SF remained an independent poor prognostic factor within the multivariate analysis and was associated with a significant higher risk of relapse and non-relapse mortality (NRM). In conclusion, our data show that elevated baseline SF has a negative impact on long-term survival in intensively treated AML patients.
