Interpretation of specification for breast cancer screening,early diagnosis,and treatment management in Chinese women

Breast cancer has become the most common malignant tumor worldwide.However,the survival rate of breast cancer patients in China is 8%lower compared to that in European and American countries.Insufficient screen-ing coverage and low rate of early detection are key problems.Therefore,it is imperative to develop a set of guidelines for breast cancer screening,early diagnosis,and treatment strategies suitable for Chinese women.The National Health Commission,the National Cancer Center,and the National Cancer Quality Control Center col-lectively organized a committee of specialists with multidisciplinary backgrounds in breast surgery,oncology,radiotherapy,diagnostic imaging,ultrasound,pathology,epidemiology,and health economics.The committee collectively published"China Breast Cancer Screening,Early Diagnosis and Treatment Specification",in which the committee outlined a set of strategies of breast cancer screening,early diagnosis,and treatment suitable for China’s national conditions.The strategies were formulated based on clinical experience in breast cancer preven-tion and treatment,characteristics of breast cancer patients in China,and socioeconomic conditions.The purpose of this article is to provide an interpretation of the above guidelines as a reference for breast cancer screening.

Early diagnosis and treatment of pulmonary embolism after total joint replacement: report of five cases

Objective To study the early diagnosis and treatment of pulmonary embolism (PE) after total joint replacement (TJR). Methods From April 1987 to December 2001, we performed 1 336 total knee replacements (TKR) in 926 patients and 1 745 total hip replacements (RHRs) in 1 566 patients. In this group there were 5 PE patients after operation. Two patients died (all after TKR), and 3 patients salvaged successfully (2 after TKR, 1 after THR). Results The total incidence of PE after TJR was 0. 2% (5/2 492), the incidence of PE after TKR was 0. 4% (4/926), and the incidence of PE after THR was 0.06% (1/1 556). In the patients who suffered PE, 2 died. The incidence of PE before 2000 was 0%. Conclusion Death after total joint replacement is due to pulmonary embolism ( PE), especially massive PE. The incidence of PE after TKR is higher than that after THR. Pulmonary angiography is the gold standard for the diagnosis of PE. With more understanding on PE and more popularity of joint replacement, the diagnosis of PE

Early Diagnosis and Treatment of Traumatic Diaphragmatic Injuries

Introduction: Early diagnosis and treatment of injuries of the diaphragm are important both because of high incidence of concomitant injuries and since they may lead to life-threatening intestinal and gastric strangulation in the late term. Herein, cases with diaphragmatic injury that have been diagnosed and operated in the early period after injury or during surgery were presented. Methods: Data of 14 cases, which have been diagnosed with diaphragmatic injury after trauma or during surgical procedure that was performed because of concomitant abdominal or intra-thoracic injury between January 2008 and April 2013, were retrospectively reviewed. Results: Of the traumatic diaphragmatic injuries, 10 (71.4%) have occurred due to penetrating trauma, whereas 4 (28.5%) have occurred due to blunt trauma. Diagnosis was made using I.V. contrast-enhanced whole abdominal and thoracic tomography in all 3 pediatric cases (21.4%) and during surgery in the others (78.5%). Conclusion: All of the diaphragmatic injuries have been accompanied by intra-abdominal or intra-thoracic organ injury that requires surgery. In these cases, the diagnosis was made on suspicion of diaphragmatic injury in the course of surgical procedure performed for concomitant organ injury. Computed tomography was diagnostic for diaphragmatic injuries in the pediatric cases.

Challenges to the early diagnosis and treatment of breast cancer in developing countries

This critical review of the literature assembles and compares available data on breast cancer clinical stage, time intervals to care, and access barriers in different countries. It provides evidence that while more than 70% of breast cancer patients in most high-income countries are diagnosed in stages Ⅰ and Ⅱ, only 20%-50% patients in the majority of low- and middleincome countries are diagnosed in these earlier stages. Most studies in the developed world show an association between an advanced clinical stage of breast cancer and delays greater than three months between symptom discovery and treatment start. The evidence assembled in this review shows that the median of this interval is 30-48 d in high-income countries but 3-8 mo in low- and middle-income countries. The longest delays occur between the first medical consultation and the beginning of treatment, known as the provider interval. The little available evidence suggests that access barriers and quality deficiencies in cancer care are determinants of provider delay in low- and middle-income countries. Research on specific access barriers and deficiencies in quality of care for the early diagnosis and treatment of breast cancer is practically non-existentin these countries, where it is the most needed for the design of cost-effective public policies that strengthen health systems to tackle this expensive and deadly disease.

The Early Diagnosis and Surgical Treatment of the Gastric Stump Carcinoma

The clinical data of 30 patients with GSC after partial gastrectomy for benign gastric dis- eases were analyzed retrospectively. Eleven cases accepted radical resection, 11 cases palliative resec- tion and the remaining 8 underwent exploratory laparotomy. It was emphasized that the detection of stump cancer at a relatively early stage, mainly due to screening programmes for gastrectomised pa- tients, was important in improving its prognosis.

Application of nanoparticles in the early diagnosis and treatment of tumors:current status and progress

Objective:Malignant tumors pose a serious threat to human life and health.Despite recent developments in modern medical techniques,the early diagnosis and treatment of tumors remain difficult due to their asymptomatic nature in the early stages of disease and the limitations in current clinical diagnostic methods.Advancements in nanotechnology,particularly in the area of multi-functional diagnostic nanomaterials,can help effectively resolve present inadequacies via concurrently achieving early diagnosis,image-guided intervention,and real-time monitoring and treatment of tumors.The development of nanomaterials and nanotechnology may also aid in the area of anti-cancer drug development by improving the safety and side-effect profile,as well as by enhancing the targeted specificity of the drugs,which are two of the long-standing challenges in Western medicine.The progress in the field of nanomaterials has also uncovered novel approaches for the clinical application of traditional Chinese medicine because the combination of traditional Chinese medicine components with nanoparticles overcomes various drawbacks,including poor water solubility,low bioavailability,and short half-life,of the former.Moreover,nanoparticles also enhance the biological effectiveness and targeted specificity of these medicines.In this review,we discuss the application of nanoparticles in the early diagnosis and treatment of tumors,through modern and traditional medicine.

Pathogenesis, diagnosis, and treatment of epilepsy: electromagnetic stimulation-mediated neuromodulation therapy and new technologies

Epilepsy is a severe,relapsing,and multifactorial neurological disorder.Studies regarding the accurate diagnosis,prognosis,and in-depth pathogenesis are crucial for the precise and effective treatment of epilepsy.The pathogenesis of epilepsy is complex and involves alterations in variables such as gene expression,protein expression,ion channel activity,energy metabolites,and gut microbiota composition.Satisfactory results are lacking for conventional treatments for epilepsy.Surgical resection of lesions,drug therapy,and non-drug interventions are mainly used in clinical practice to treat pain associated with epilepsy.Non-pharmacological treatments,such as a ketogenic diet,gene therapy for nerve regeneration,and neural regulation,are currently areas of research focus.This review provides a comprehensive overview of the pathogenesis,diagnostic methods,and treatments of epilepsy.It also elaborates on the theoretical basis,treatment modes,and effects of invasive nerve stimulation in neurotherapy,including percutaneous vagus nerve stimulation,deep brain electrical stimulation,repetitive nerve electrical stimulation,in addition to non-invasive transcranial magnetic stimulation and transcranial direct current stimulation.Numerous studies have shown that electromagnetic stimulation-mediated neuromodulation therapy can markedly improve neurological function and reduce the frequency of epileptic seizures.Additionally,many new technologies for the diagnosis and treatment of epilepsy are being explored.However,current research is mainly focused on analyzing patients’clinical manifestations and exploring relevant diagnostic and treatment methods to study the pathogenesis at a molecular level,which has led to a lack of consensus regarding the mechanisms related to the disease.

Improving early diagnosis of multiple endocrine neoplasia type 1 by assessing the gastrointestinal symptoms,hypercalcemia,and elevated serum gastrin

Despite advancements in the field,early diagnosis of multiple endocrine neoplasia type 1(MEN1)remains unachievable.This letter to the editor highlighted the importance of carefully assessing gastrointestinal symptoms,hypercalcemia,and elevated serum gastrin levels,as suggested by Yuan et al in their paper.They focused on a patient with recurrent abdominal pain and diarrhea whose diagnostic path led to establishing a MEN1 diagnosis within a year.This emphasized the need for clinicians to consider MEN1 in patients with similar presentations,particularly when gastrointestinal symptoms persist or recur after discontinuation of proton pump inhibitors,especially knowing that early recognition and intervention are crucial for improving patient outcomes.

Early diagnosis of esophageal cancer:How to put“early detection”into effect?

This editorial comments on the article by Qu et al in a recent edition of World Journal of Gastrointestinal Oncology,focusing on the importance of early diagnosis in managing esophageal cancer and strategies for achieving“early detection”.The five-year age-standardized net survival for esophageal cancer patients falls short of expectations.Early detection and accurate diagnosis are critical strategies for improving the treatment outcomes of esophageal cancer.While advancements in endoscopic technology have been significant,there seems to be an excessive emphasis on the latest high-end endoscopic devices and various endoscopic resection techniques.Therefore,it is imperative to redirect focus towards proactive early detection strategies for esophageal cancer,investigate the most cost-effective screening methods suitable for different regions,and persistently explore practical solutions to improve the five-year survival rate of patients with esophageal cancer.

Early Treatment Outcome of Humeral Shaft Fracture Non-Union in Adults: Comparative Study of Plating versus Interlocking Nailing

Background: Fractures of humeral shaft in adults are common injuries. Humeral shafts non-union either from late presentation after initial treatment by traditional bone setters or failed non-operative orthodox care is a major problem in this part of the world. This non-union is a major treatment challenge with increased cost of care and morbidity in this part of the world. Humeral shaft non-union can be treated with locked intra-medullary nailing (LIMN) or dynamic compression plating (DCP). Study on comparison of these methods of fixation in this part of the world is scarce in literature search, hence the reason for this study. Objective: The objectives of this study are: (1) to compare early clinical outcome following fixation of humeral shaft fracture nonunion with DCP versus LIMN;(2) to compare the time of radiologic fracture union of DCP with LIMN;(3) to compare complications following fixation of humeral shaft fracture nonunion with DCP versus LIMN. Patients and Methods: This was a randomized control study done for 2 years in which fifty adult patients with humeral shaft non-union were recruited. The patients were grouped into 2 (P = DCP & N = LIMN). Forty five of the patients completed the follow up periods of the study and then analyzed. The P group had ORIF with DCP while the N group had ORIF with LIMN. Both groups had grafting with cancellous bones. Each patient was followed up for a period of 6 months at the time which radiographic union is expected. Any patient without clinical and/or radiographic evidence of union after six months of surgery was diagnosed as having recurrent non-union. The data generated was analyzed using SPSS Version 23. The results were presented in charts and tables. The paired t-test was used while considering p value Result: Forty five patients completed follow up. There was a male preponderance (4:1), right humerus predominated (3:2). Motor vehicular accidents were the commonest cause of the fractures (62%). Most non-union fractures occurred at the level of the middle 3rd of the humeral shaft (60%). Failed TBS treatment was the commonest indication for the osteosynthesis (71%). More patients had plating (53%) compared to 47% who had LIMN. Most patients (93.4%) had union between 3 to 6 months irrespective of fixation type with no significant statistical difference between the union rate of DCP and LIMN (p value 0.06) with similar functional outcome and complication rates irrespective of the type of fixation. Conclusion: This study showed that the success rates in term of fracture union, outcome functional grades and complication rates were not directly dependent on the types of the fixation: plating or locked intra-medullary nailing.

Clinical significance of peripheral blood UL16 and DR-70 for the early diagnosis and prognostic evaluation of colorectal cancer

BACKGROUND Early diagnosis of colorectal cancer(CRC)is of great significance to improve the survival rate and quality of life of patients,but early diagnosis of CRC requires more sensitive techniques.Peripheral blood UL16-binding protein 2(ULBP2)and human fibrinogen degradation products(DR-70)are the main indicators for the diagnosis of malignant tumors.AIM To assess ULBP2 and DR-70 potential for the early diagnosis and prognostic evaluation of CRC to provide a reference.METHODS This study involved 60 patients with early-stage CRC(CRC group),50 patients with benign colorectal tumors(benign group),and 50 healthy patients(control group)enrolled at the Affiliated Hospital of Jiangnan University and Jiangsu Province Official Hospital between January,2020 and January,2022.ULBP2 and DR-70 levels in the blood were determined and differences among the three groups and early diagnostic values for CRC were determined.Patients with CRC were divided into the good prognosis and poor prognosis groups,and ULBP2 and DR-70 levels in the blood and diagnostic values were compared.RESULTS ULBP2 and DR-70 serum levels were significantly higher in the CRC group than in the control and benign groups(P<0.05);however,no significant differences were observed between the benign and control groups(P>0.05).Among the 60 patients with CRC followed up for two years,two died(3.33%)and 15 exhibited tumor metastasis,progression,or recurrence(25.00%).ULBP2 and DR-70 serum levels were significantly higher in the poor prognosis group than in the good prognosis group(P<0.05).A receiver operating characteristic curve was plotted.Area under the curve,sensitivity,and specificity of serum ULBP2 with DR-70 for the early diagnosis of CRC were higher than those of the single serum indices(P<0.05)in both the good and poor prognosis groups.CONCLUSION ULBP2 and DR-70 serum levels were significantly high in patients with early-stage CRC.They improved the diagnostic rate of early-stage CRC and predicted patient prognosis,thereby showing clinical application potential.

COVID-19 mortality paradox(United States vs Africa):Mass vaccination vs early treatment

The coronavirus disease 2019(COVID-19)mortality rate in 55 African countries is almost 4.5 times lower than in the coronavirus disease 2019(COVID-19)despite Africa having over 4.2 times more people.This mortality paradox is also evident when comparing Nigeria,a heavily populated,poorly vaccinated and weakly mandated country to Israel,a small,highly vaccinated and strictly mandated country.Nigeria has almost 4 times lower COVID mortality than Israel.In this Field of Vision perspective,I explain how this paradox has evolved drawing upon my academic,clinical and social experience.Since April 2020,I’ve developed and been using the Egyptian immune-modulatory Kelleni’s protocol to manage COVID-19 patients including pediatric,geriatric,pregnant,immune-compromised and other individuals suffering from multiple comorbidities.It’s unfortunate that severe acute respiratory syndrome coronavirus 2 is still evolving accompanied by more deaths.However in Africa,we’ve been able to live without anxiety or mandates throughout the pandemic because we trust science and adopted early treatment using safe,and effective repurposed drugs that have saved the majority of COVID-19 patients.This article represents an African and Egyptian tale of honor.

Esophageal cancer screening,early detection and treatment:Current insights and future directions

Esophageal cancer ranks among the most prevalent malignant tumors globally,primarily due to its highly aggressive nature and poor survival rates.According to the 2020 global cancer statistics,there were approximately 604000 new cases of esophageal cancer,resulting in 544000 deaths.The 5-year survival rate hovers around a mere 15%-25%.Notably,distinct variations exist in the risk factors associated with the two primary histological types,influencing their worldwide incidence and distribution.Squamous cell carcinoma displays a high incidence in specific regions,such as certain areas in China,where it meets the cost-effect-iveness criteria for widespread endoscopy-based early diagnosis within the local population.Conversely,adenocarcinoma(EAC)represents the most common histological subtype of esophageal cancer in Europe and the United States.The role of early diagnosis in cases of EAC originating from Barrett's esophagus(BE)remains a subject of controversy.The effectiveness of early detection for EAC,particularly those arising from BE,continues to be a debated topic.The variations in how early-stage esophageal carcinoma is treated in different regions are largely due to the differing rates of early-stage cancer diagnoses.In areas with higher incidences,such as China and Japan,early diagnosis is more common,which has led to the advancement of endoscopic methods as definitive treatments.These techniques have demonstrated remarkable efficacy with minimal complications while preserving esophageal functionality.Early screening,prompt diagnosis,and timely treatment are key strategies that can significantly lower both the occurrence and death rates associated with esophageal cancer.
