The study aimed to describe the baseline clinical-pathological profile and treatment modalities for primary brain tumors in adults treated at the Ocean Road Cancer Institute (ORCI) from 2017 to 2020. Materials and Methods: This was a retrospective study conducted at ORCI by reviewing 61 medical records of patients with primary brain tumors over the age of 15 from January 2017 to December 2020. A structured questionnaire was used to retrieve information on sociodemographic, clinical-pathological characteristics, and treatment modalities. The 2007 WHO classification system and the International Classification of Cancer Diseases (ICD-0-3) were used for classification and diagnosis. The X<sup>2</sup> test and Fisher’s exact test were used to compare the proportions and an independent t-test was used to compare the means. A P-value less than 0.05 was deemed statistically significant. The Results: The mean age of the females was 41.8 years and the mean age of males was 42.9 years. Overall M: F ratio was 1:1.2. Meningioma was the only tumor that was more commonly found in women with M:F of 1:2.1. The most prevalent symptom was headache (57.4%). Glioblastoma (GBM) was the most common tumor among adults (38%), followed by astrocytomas (23%) and meningioma (18%). Approximately 91.8% of all tumors occurred in the supratentorial region. The Frontal lobe was the most common site (29.5%). Approximately 81.9% of patients received surgery. The gross tumor resection (GTR) rate was 26.2%, and the subtotal tumor resection (STR) rate was 55.7%. Roughly 18% of the tumors were inoperable. An estimated 80.3% of respondents received radiation therapy. The radiotherapy technique was 3DCRT in two-thirds of the patients and the rest received conventional 2D radiotherapy. The mean equivalent dose in the 2 Gy fractions (EQD2) was 43.9 Gy. Respondents with low-grade intracranial tumors were treated with a mean EQD2 of 47.3 Gy, while those with high-grade intracranial tumors were treated with a mean EQD2 of 44.3 Gy and the difference was statistically significant. Only half of the patients who received adjuvant radiotherapy received it concurrently with chemotherapy. Temozolomide was the most widely used cytotoxic medication. Conclusion: Mean age of the patients was 41 years old. Most tumors were in the supratentorial area and GBM was the most common tumor. Only meningioma was a bit more common amongst females. Overall, radiotherapy doses and the gross tumor resection rates were low. Concurrent chemotherapy with radiotherapy was given to a few patients.展开更多

In recent years, given the accumulating evidence that prediabetes is also related to increasing risk of CAD including cardiovascular events, a new guideline has been proposed for the treatment of blood cholesterolfor primary prevention of cardiovascular events. This guideline recommends aggressive lipid-lowering statin therapy for primary prevention in diabetes and other patients. The ultimate goal of patient management is to inhibit progression of systemic atherosclerosis and prevent fatal cardiovascular events such as acute coronary syndrome(ACS). Because disruption of atherosclerotic coronary plaques is a trigger of ACS, the high-risk atheroma is called a vulnerable plaque. Several types of novel diagnostic imaging technologies have been developed for identifying the characteristics of coronary atherosclerosis before the onset of ACS, especially vulnerable plaques. According to coronary angioscopic evaluation, atherosclerosis severity and plaque vulnerability were more advanced in prediabetic than in nondiabetic patients and comparable to that in diabetic patients. In addition, pharmacological intervention by statin therapy changed plaque color and complexity, and the dynamic changes in plaque features are considered plaque stabilization. In this article, we review the findings of atherosclerosis in prediabetes, detected by intravascular imaging modalities, and the therapeutic implications.展开更多

The use of each modalityis generally linked to particular brain regions, but it is not yet known whether the cellular morphology of neurons in these regions has evolved in association with the relative use of a modality.We investigated relationships between the behavioral use of communication modalities and neural morphologies in six lizard species. Two of these species （Anolis carol# nensis and Leiocephalus carinatus） primarily use visual signals to communicate with conspecifics and detect potential prey, and two （Aspidoscelis gularis and Scincella lateralis） communicate and forage primarily using chemical signals. Two other species （Hemidactylus turcicus and Sceloporus olivaceus） use both visual and chemical signals. For each species, we performed beha- vioral observations and quantified rates of visual and chemical behaviors. We then cryosectioned brain tissues from 9-10 males of each species and measured the soma size and density of neurons in two brain regions associated with visual behaviors （the lat- eral geniculate nucleus and the nucleus rotundus） and one region associated with chemical behaviors （the nucleus sphericus）. With analyses conducted in a phylogenetic context, we found that species that performed higher rates of visual displays had a denser lateral geniculate nucleus, and species that used a higher proportion of chemical displays had larger somas in the nucleus sphericus. These relationships suggest that neural morphologies in the brain have evolved convergently in species with similar communication behaviors .展开更多

Prognosis depends on the extent of invasion of adjacent tissues whereby multimodality treatment including surgery with or without adjuvant chemoradiotherapy is the preferred approach for locally advanced thymomas. For metastatic thymomas, only few chemotherapeutic options are available. We report 2 cases of patients with metastatic thymic malignancies with a dramatic response on pemetrexed treatment. The choice for this antifolate therapy is based upon a small series. Because metastatic thymic neoplasm is a rare disease, large randomised trials are not feasible. Case reports on the treatment of these malignancies are very important and can provide readers with the opportunity to deal with rare dis- eases.展开更多

According to coronary angioscopic evaluation, atherosclerosis severity and plaque vulnerability were more advanced in prediabetic than in nondiabetic patients and comparable to that in diabetic patients. In addition, pharmacological intervention by statin therapy changed plaque color and complexity, and the dynamic changes in plaque features are considered plaque stabilization. In this article, we review the findings of atherosclerosis in prediabetes, detected by intravascular imaging modalities, and the therapeutic implications.

文摘Animals communicate information within their environments via visual, chemical, auditory, and/or tactile modalities. The use of each modalityis generally linked to particular brain regions, but it is not yet known whether the cellular morphology of neurons in these regions has evolved in association with the relative use of a modality.We investigated relationships between the behavioral use of communication modalities and neural morphologies in six lizard species. Two of these species （Anolis carol# nensis and Leiocephalus carinatus） primarily use visual signals to communicate with conspecifics and detect potential prey, and two （Aspidoscelis gularis and Scincella lateralis） communicate and forage primarily using chemical signals. Two other species （Hemidactylus turcicus and Sceloporus olivaceus） use both visual and chemical signals. For each species, we performed beha- vioral observations and quantified rates of visual and chemical behaviors. We then cryosectioned brain tissues from 9-10 males of each species and measured the soma size and density of neurons in two brain regions associated with visual behaviors （the lat- eral geniculate nucleus and the nucleus rotundus） and one region associated with chemical behaviors （the nucleus sphericus）. With analyses conducted in a phylogenetic context, we found that species that performed higher rates of visual displays had a denser lateral geniculate nucleus, and species that used a higher proportion of chemical displays had larger somas in the nucleus sphericus. These relationships suggest that neural morphologies in the brain have evolved convergently in species with similar communication behaviors .

文摘Thymomas are rare and usually slowly growing tumors, originating from the epithelial layer of the thymus. Prognosis depends on the extent of invasion of adjacent tissues whereby multimodality treatment including surgery with or without adjuvant chemoradiotherapy is the preferred approach for locally advanced thymomas. For metastatic thymomas, only few chemotherapeutic options are available. We report 2 cases of patients with metastatic thymic malignancies with a dramatic response on pemetrexed treatment. The choice for this antifolate therapy is based upon a small series. Because metastatic thymic neoplasm is a rare disease, large randomised trials are not feasible. Case reports on the treatment of these malignancies are very important and can provide readers with the opportunity to deal with rare dis- eases.

文摘The recognition of dairy cow behavior is essential for enhancing health management,reproductive efficiency,production performance,and animal welfare.This paper addresses the challenge of modality loss in multimodal dairy cow behavior recognition algorithms,which can be caused by sensor or video signal disturbances arising from interference,harsh environmental conditions,extreme weather,network fluctuations,and other complexities inherent in farm environments.This study introduces a modality mapping completion network that maps incomplete sensor and video data to improve multimodal dairy cow behavior recognition under conditions of modality loss.By mapping incomplete sensor or video data,the method applies a multimodal behavior recognition algorithm to identify five specific behaviors:drinking,feeding,lying,standing,and walking.The results indicate that,under various comprehensive missing coefficients(λ),the method achieves an average accuracy of 97.87%±0.15%,an average precision of 95.19%±0.4%,and an average F1 score of 94.685%±0.375%,with an overall accuracy of 94.67%±0.37%.This approach enhances the robustness and applicability of cow behavior recognition based on multimodal data in situations of modality loss,resolving practical issues in the development of digital twins for cow behavior and providing comprehensive support for the intelligent and precise management of farms.

文摘Non-alcoholic fatty liver disease (NAFLD) is a burgeoning global health concern.In the subset of NAFLD patients with non-alcoholic steatohepatitis (NASH),the presence of significant fibrosis at index assessment is associated with poor prognosis and increased mortality.Hence,there is a growing need to accurately assess and stage fibrosis.Liver biopsy,the current gold standard,has limitations with sampling error and is invasive,with associated inherent risk.This has led to a host of non-invasive means of assessing fibrosis,which has garnered relevance in a disease that requires serial assessment of fibrosis longitudinally over time.This review discusses,comprehensively,the various tools available to the clinician for the assessment of fibrosis,including the various scoring systems used in liver biopsy,the non-invasive means of serum biomarkers,such as the highly-validated NAFLD fibrosis score,and the imaging-based modalities,such as transient elastography and magnetic resonance elastography.

文摘Adult T-cell lymphoblastic lymphoma(T-LBL)is a rare and aggressive subtype of non-Hodgkin’s lymphoma that differs from pediatric T-LBL and has a worse prognosis.Due to its rarity,little is known about the genetic and molecular characteristics,optimal treatment modalities,and prognostic factors of adult T-LBL.Therefore,we summarized the existing studies to comprehensively discuss the above issues in this review.Genetic mutations of NOTCH1/FBXW7,PTEN,RAS,and KMT2D,together with abnormal activation of signaling pathways,such as the JAK-STAT signaling pathway were described.We also discussed the therapeutic modalities.Once diagnosed,adult T-LBL patients should receive intensive or pediatric acute lymphoblastic leukemia regimen and central nervous system prophylaxis as soon as possible,and cranial radiation-free protocols are appropriate.Mediastinal radiotherapy improves clinical outcomes,but adverse events are of concern.Hematopoietic stem cell transplantation may be considered for adult T-LBL patients with high-risk factors or those with relapsed/refractory disease.Besides,several novel prognostic models have been constructed,such as the 5-miRNAs-based classifier,11-gene-based classifier,and 4-CpG-based classifier,which have presented significant prognostic value in adult T-LBL.
