In contrast with computed tomography, the tumor exhibited hypervascularity and was fed from the 9th intercostals artery. Histologically, the tumor was diagnosed as a cellular variant of solitary fibrous tumor of the pleura, with branching “staghorn” vessels and hypervascularity. The tumor thus resembled a chest wall hemangiopericytoma.展开更多

METHODS： Between August 2000 and June 2003, 134 pathologically-proven esophageal squamous cell carcinoma male patients and 237 male controls were recruited from Kaohsiung Medical University Hospital and Kaohsiung Veterans General Hospital in southern Taiwan. ADH2 and ALDH2 polymorphisms were genotyped using PCR-RFLP. RESULTS： Compared to those with ADH2＊2/＊2, individuals with ADH2＊1/＊2 and ADH2＊1/＊1 had 2.28- and 7.14-fold, respectively, increased risk of developing esophageal cancer （95%CI = 1.11-4.68 and 2.76-18.46） after adjusting for alcohol consumption and other covariates. The significant increased risk was also noted among subjects with ALDH2＊1/＊2 （adjusted OR （AOR） = 5.25, 95%CI = 2.47-11.19）, when compared to those with ALDH2＊1/＊1. The increased risk of esophageal cancer was made greater, when subjects carried both ADH2＊1/＊1 and ALDH2＊1/＊2, compared to those with ADH2＊1/＊2 or ADH2＊2/＊2 and ALDH2＊1/＊1 （AOR = 36.79,95%a = 9.36-144.65）. Furthhermore, we found a multipticative effect of lifetime alcoholic consumption and genotypes （ADH2 and ALDH2） on esophageal cancer risk. CONCLUSION： Our findings suggest that polymorphisms of ADH2 and ALDH2 can modify the influence of alcoholic consumption on esophageal cancer risk.展开更多

The aim of this study was to compare the features of elderly versus younger patients diagnosed with PAH, and to define the prognostic factors which affect their long-term survival. Methods In this prospective, single center study, the clinical, echocardiographic, hemodynamic characteristics, and the outcomes of younger （18-65 years） and elderly （〉 65 years） patients with definitive diagnosis of precapillary PAIl were compared. Results A total of 119 patients were analyzed in this study; 43 were elderly （mean age： 71.5 ± 5.5 years）, while 76 were non-elderly （mean age 44.5 ±15.2 years）. During the mean follow-up duration of 26.8 ±25.0 months, 43 deaths occurred, 17 of which were among the elderly group, with 28 among non-elderly group. Comparison of baseline parameters showed that 6 min walking distance, hemoglobin levels, pulmonary artery pressures and pulmonary vascular resistance were significantly lower; and estimated glomerular filtration rate, body mass index, E/e＇ and pulmonary capillary wedge pressure were significantly higher in the elderly group than in the younger group. Survival analysis demonstrated that the independent predictors of death were tricuspid plane annular systolic excursion （TAPSE; HR： 1.272, 95% CI： 1.079-1.499, P = 0.004） and uric acid （HR： 1.291, 95% CI： 1.042-1.600, P = 0.019） in the elderly group. In contrast, in the non-elderly group, higher brain natriuretic peptide （HR： 1.002, 95% CI： 1.001-1.004, P 〈 0.001） and higher right atrial pressure （HR： 1.128, 95% CI： 1.026-1.241, P = 0.013） values were the only parameters associated with mortality. Conclusions Our data suggest that elderly PAH patients have a unique clinical and hemodynamic profile, with totally different prognostic markers compared to younger PAH patients.展开更多

Methods: It was a descriptive study that had investigated the co-morbidity of depression and anxiety among tuberculosis patients with reference to gender. This study was conducted in Jinnah Post Graduate Medical Centre—Chest ward (TB clinic) from July 2014 to September 2014. Hundred diagnosed patients of tuberculosis (50 males and 50 females) were randomly selected. Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Questionnaire (GAD-7) were used to assess the level of anxiety and depression. Results: Findings indicated that 56% tuberculosis (TB) patients had moderate to severe level of depression, whereas 65% TB patients had moderate to severe level of anxiety. Female patients had significantly high prevalence of depression as compared to males (t = –2.173, P –3.468, P Conclusion: Likelihood of depression and anxiety was frequent in tuberculosis patients. However, better management of these psychiatric morbidities may improve treatment adherence, illness perception and patient coping skills.展开更多

All of the original articles were evaluated according to date of publications, countries, clinics and topics. Studies about occlusive vascular diseases were evaluated according to their qualifications, review methods and results. SPSS for Windows 16.0 was used in data analysis and data were expressed as mean, standard deviation and percentage.RESULTS: A total of 735 original research articles were investigated. The number of publications have shown a regular logarithmic increase over the years. Thirty-two percent of all publications were performed by clinics in Turkey and 56.4% were performed by general-oncological surgery and cardiology clinics. A total of 107 publications were identified to be about occlusive vascular diseases, 80.3% of these publications were found to be prognostic and 19.6% to be diagnostic, 82.2% of them were found to be planned as retrospective and 17.7% as prospective. In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.展开更多

Blood examination showed elevated levels of hepatobiliary enzymes. Abdominal computed tomography showed a tumor with peripheral enhancement in the pancreatic head, accompanied with the dilatation of intra- and extra-hepatic bile ducts. He was diagnosed as having obstructive jaundice caused by a pancreatic head tumor. The pancreatic head tumor was presumably diagnosed as the metastasis of malignant solitary fibrous tumor of the pleura, because the findings on the pancreatic head tumor on abdominal CT were similar to those on the primary lung lesion of malignant solitary fibrous tumor of the pleura. The pancreatic tumor grew rapidly after the implantation of metallic stent in the inferior part of the common bile duct. The patient died of lymphangitis carcinomatosa of the lungs. Autopsy revealed a tumor that spread from the pancreatic head to the hepatic hilum. Microscopically, spindle-shaped cells exhibiting nuclear atypicality or division together with collagen deposition were observed. Immunohistochemically the pancreatic head tumor cells were negative for staining of α-smooth muscle actin （α-SMA） or CD117, but positive for vimentin, CD34 and CD99. These findings are consistent with those on malignant solitary fibrous tumor of the pleura. We report the first case of obstructive jaundice caused by a secondary pancreatic tumor from malignant solitary fibrous tumor of the pleura.展开更多

Delay in treatment initiation can occur while awaiting histo-microbiologic confirmation owing to the paucibacillary nature of the disease. Sago-like nodules are the most common visual finding on gross thoracoscopic appearance. The primary objective was to determine the diagnostic utility of the presence of sago-like nodules on gross thoracoscopic appearance in TPE to help justify early initiation of tuberculosis (TB) treatment based on their finding while awaiting final histo-microbiologic confirmation. Secondary objective was to study the correlation between the presence of sago-like nodules and the final histo-microbiologic findings in pleural biopsy specimens. Methods: This was a retrospective-descriptive study of all patients with exudative pleural effusion who underwent diagnostic medical thoracoscopy (MT) at Hamad General Hospital during an eight-year period (from January, 2008 to December, 2015). Results: The presence of sago-like nodules on gross thoracoscopic appearance of the pleural surface had a sensitivity of 58%, a specificity of 89% and a positive predictive value of 97% for TPE with a diagnostic accuracy of 62%. There is significant association between the presence of sago-like nodules and demonstration of granulomatous inflammation in pleural biopsy specimens (P = 0.000). There is no association between sago-like nodules and positive TB smear and culture in biopsy specimens. Conclusion: The presence of sago-like nodules on gross thoracoscopic appearance has a high specificity and positive predictive value for TPE and significantly correlates with the presence of granulomatous inflammation. Patients from TB prevalent areas with exudative pleural effusion and sago-like nodules on gross thoracoscopic appearance may be commenced on TB chemotherapy while awaiting final histologic confirmation.展开更多

FDG-PET is a non invasive diagnostic tool that is being used increasingly in the diagnosis of lung cancer. This study evaluates the prognostic values of PET/CT defined SUV measurements and other patient/tumor characteristics in newly diagnosed stage IIIB and IV NSCLC. Method: This ret- rospective study included 111 patients admitted between 2005 and 2006 with stage IIIB and IV NSCLC, whose diag- noses were verified with biopsy and staging performed with PET/CT. The prognostic values of standart uptake values (SUV) of the primary lesion on PET/CT, and other patient/tumor characteristics were analyzed using survival analysis. Results: SUV was found to be unrelated with survival. Only the presence of distant metastasis, type of metastasis (bone, brain, or the contralateral lung) and the type of radiotherapy used (curative or palliative) were found to be related to survival. SUV values in epidermoid carcinoma were found to be significantly higher compared to adenocarcinoma (16.15 ± 7.18 and 12.32 ± 5.52, respectively, p = 0.021).Conclusion: Our findings do not support that SUV of the pri- mary lesion in inoperable NSCLC has a prognostic value with respect to survival. This condition may be explained by the inclusion of significantly advanced NSCLC patients who are known to have a low survival and a high mortality, and also the relatively small sampling size.展开更多

These stimulatory effects on colonic motility and/or secretion from acyl ghrelin and des-acyl ghrelin disappeared when the ICV injection volume increased to 10 μL compared with saline controls(10 μL/rat). Additionally, the ICV injection of 10 μL of saline significantly shortened the colonic transit time compared with the ICV injection of 5 μL of saline. The total fecal weight during the first hour post-injection correlated with the colonic transit time and fecal pellet output after the ICV injection of acyl ghrelin(1 nmol/5 μL), whereas the total fecal weight during the first hour post-injection correlated with the fecal pellet output but not the colonic transit time after the ICV injection of des-acyl ghrelin(1 nmol/5 μL).CONCLUSION Colonic secretion does not always correlate with colonic motility in response to different colonic stimulations. Acyl ghrelin stimulates colonic secretion.展开更多

文摘Objectives:Professional antigen-presenting cells known as dendritic cells(DCs)assist as a connection between the innate and adaptive components of the immune response.DCs are attractive targets for immunomodulatory drugs because of their crucial function in triggering immunity.This study set out to examine,for the first time,how hibifolin affected mouse bone-marrow derived(BMDCs)dendritic cells,triggered by lipopolysaccharide(LPS)in vitro.Additionally,a mouse model of contact hypersensitivity(CHS)was used to assess its possible therapeutic effects in vivo.Methods:LPS was administered to BMDCs with or without hibifolin.Major Histocompatibility Complex(MHC)class II,cytokine production,and co-stimulatory molecule(CD80,CD86)expression levels were assessed.To evaluate the functional effects on T-cell activation,mixed lymphocyte responses using OVA specific T-cells were conducted.In vivo,immunoregulatory potential of hibifolin was examined using a CHS mouse model sensitized with 2,4-dinitrofluorobenzene(DNFB).Results:Hibifolin significantly reduced the expression of the proinflammatory cytokines TNF-αand IL-6,as well as the costimulatory molecules CD80,CD86,and MHC II induced by LPS,by about 40-50%.These effects were associated with reduced NF-κB and p38-MAPK pathway activity.JNK and ERK phosphorylation levels did not alter significantly.In vitro,BMDCs treated with hibifolin showed a 40%-45%down-regulated capacity to stimulate T-cell propagation and IFN-γrelease.Oral hibifolin treatment in vivo modestly decreased DNFB-induced CHS responses by 30%-40%.Conclusion:Overall,our results offer new insights that by inhibiting NF-κB and p38-MAPK signaling,hibifolin decreases the expression of costimulatory molecules and cytokines,thereby limiting BMDC activation,suppressing T-cell responses,and exerting immunomodulatory effects in the CHS mouse model.
文摘BACKGROUND Early gastric cancer(EGC)is a common malignant tumor of the digestive system,and its lymph node metastasis and survival prognosis have been concerning.By retrospectively analyzing the clinical data of EGC patients,we can better under-stand the status of lymph node metastasis and its impact on survival and prog-nosis.AIM To evaluate the prognosis of EGC patients and the factors that affect lymph node METHODS The clinicopathological data of 1011 patients with EGC admitted to our hospital between January 2015 and December 2023 were collected in a retrospective cohort study.There were 561 males and 450 females.The mean age was 58±11 years.The patient underwent radical gastrectomy.The status of lymph node metastasis in each group was determined according to the pathological examination results of surgical specimens.The outcomes were as follows:(1)Lymph node metastasis in EGC patients;(2)Analysis of influencing factors of lymph node metastasis in EGC;and(3)Analysis of prognostic factors in patients with EGC.Normally distributed measurement data are expressed as mean±SD,and a t test was used for comparisons between groups.The data are expressed as absolute numbers or percentages,and the chi-square test was used for comparisons between groups.Rank data were compared using a nonparametric rank sum test.A log-rank test and a logistic regression model were used for univariate analysis.A logistic stepwise regression model and a Cox stepwise regression model were used for multivariate analysis.The Kaplan-Meier method was used to calculate the survival rate and construct survival curves.A log-rank test was used for survival analysis.RESULTS Analysis of influencing factors of lymph node metastasis in EGC.The results of the multifactor analysis showed that tumor length and diameter,tumor site,tumor invasion depth,vascular thrombus,and tumor differentiation degree were independent influencing factors for lymph node metastasis in patients with EGC(odds ratios=1.80,1.49,2.65,5.76,and 0.60;95%CI:1.29–2.50,1.11–2.00,1.81–3.88,3.87-8.59,and 0.48-0.76,respectively;P<0.05).Analysis of prognostic factors in patients with EGC.All 1011 patients with EGC were followed up for 43(0–13)months.The 3-year overall survival rate was 97.32%.Multivariate analysis revealed that age>60 years and lymph node metastasis were independent risk factors for prognosis in patients with EGC(hazard ratio=9.50,2.20;95%CI:3.31-27.29,1.00-4.87;P<0.05).Further analysis revealed that the 3-year overall survival rates of gastric cancer patients aged>60 years and≤60 years were 99.37%and 94.66%,respectively,and the difference was statistically significant(P<0.05).The 3-year overall survival rates of patients with and without lymph node metastasis were 95.42%and 97.92%,respectively,and the difference was statistically significant(P<0.05).CONCLUSION The lymph node metastasis rate of EGC patients was 23.64%.Tumor length,tumor site,tumor infiltration depth,vascular cancer thrombin,and tumor differentiation degree were found to be independent factors affecting lymph node metastasis in EGC patients.Age>60 years and lymph node metastasis are independent risk factors for EGC prognosis.
文摘We present a case report of a 65-year-old woman who underwent resection of a chest wall tumor. In contrast with computed tomography, the tumor exhibited hypervascularity and was fed from the 9th intercostals artery. Histologically, the tumor was diagnosed as a cellular variant of solitary fibrous tumor of the pleura, with branching “staghorn” vessels and hypervascularity. The tumor thus resembled a chest wall hemangiopericytoma.

文摘AIM： To investigate the association between the genetic polymorphisms of ADH2 and ALDH2, lifetime alcohol consumption and esophageal cancer risk in the Taiwan Residents men. METHODS： Between August 2000 and June 2003, 134 pathologically-proven esophageal squamous cell carcinoma male patients and 237 male controls were recruited from Kaohsiung Medical University Hospital and Kaohsiung Veterans General Hospital in southern Taiwan. ADH2 and ALDH2 polymorphisms were genotyped using PCR-RFLP. RESULTS： Compared to those with ADH2＊2/＊2, individuals with ADH2＊1/＊2 and ADH2＊1/＊1 had 2.28- and 7.14-fold, respectively, increased risk of developing esophageal cancer （95%CI = 1.11-4.68 and 2.76-18.46） after adjusting for alcohol consumption and other covariates. The significant increased risk was also noted among subjects with ALDH2＊1/＊2 （adjusted OR （AOR） = 5.25, 95%CI = 2.47-11.19）, when compared to those with ALDH2＊1/＊1. The increased risk of esophageal cancer was made greater, when subjects carried both ADH2＊1/＊1 and ALDH2＊1/＊2, compared to those with ADH2＊1/＊2 or ADH2＊2/＊2 and ALDH2＊1/＊1 （AOR = 36.79,95%a = 9.36-144.65）. Furthhermore, we found a multipticative effect of lifetime alcoholic consumption and genotypes （ADH2 and ALDH2） on esophageal cancer risk. CONCLUSION： Our findings suggest that polymorphisms of ADH2 and ALDH2 can modify the influence of alcoholic consumption on esophageal cancer risk.

文摘Backgrounds Pulmonary arterial hypertension （PAH） was previously considered an illness that affects mostly the young, but now it is also increasingly recognized in the elderly. The aim of this study was to compare the features of elderly versus younger patients diagnosed with PAH, and to define the prognostic factors which affect their long-term survival. Methods In this prospective, single center study, the clinical, echocardiographic, hemodynamic characteristics, and the outcomes of younger （18-65 years） and elderly （〉 65 years） patients with definitive diagnosis of precapillary PAIl were compared. Results A total of 119 patients were analyzed in this study; 43 were elderly （mean age： 71.5 ± 5.5 years）, while 76 were non-elderly （mean age 44.5 ±15.2 years）. During the mean follow-up duration of 26.8 ±25.0 months, 43 deaths occurred, 17 of which were among the elderly group, with 28 among non-elderly group. Comparison of baseline parameters showed that 6 min walking distance, hemoglobin levels, pulmonary artery pressures and pulmonary vascular resistance were significantly lower; and estimated glomerular filtration rate, body mass index, E/e＇ and pulmonary capillary wedge pressure were significantly higher in the elderly group than in the younger group. Survival analysis demonstrated that the independent predictors of death were tricuspid plane annular systolic excursion （TAPSE; HR： 1.272, 95% CI： 1.079-1.499, P = 0.004） and uric acid （HR： 1.291, 95% CI： 1.042-1.600, P = 0.019） in the elderly group. In contrast, in the non-elderly group, higher brain natriuretic peptide （HR： 1.002, 95% CI： 1.001-1.004, P 〈 0.001） and higher right atrial pressure （HR： 1.128, 95% CI： 1.026-1.241, P = 0.013） values were the only parameters associated with mortality. Conclusions Our data suggest that elderly PAH patients have a unique clinical and hemodynamic profile, with totally different prognostic markers compared to younger PAH patients.
文摘BACKGROUND Coronavirus disease 2019(COVID-19)has a spectrum of clinical syndromes with serious involvement of the lung and frequent effection of the liver and hemostatic system.Blood biomarkers are affordable,rapid,objective,and useful in the evaluation and prognostication of COVID-19 patients.AIM To investigate the association between aspartate transferase-to-platelet ratio index(APRI)and in-hospital mortality to develop a COVID-19 mortality prediction model.METHODS A multicenter cohort study with a retrospective design was conducted.Medical records of all consecutive adult patients admitted to Al-Azhar University Hospital(Assiut,Egypt)and Chest Hospital(Assiut,Egypt)with confirmed COVID-19 from July 1,2020 to October 1,2020,were retrieved and analyzed.The patient cohort was classified into the following two categories based on the APRI:(1)COVID-19 presenting with APRI≤0.5;and(2)COVID-19 presenting with APRI(>0.5 and≤1.5).The association between APRI and all-cause in-hospital mortality was analyzed,and the new model was developed through logistic regression analyses.RESULTS Of the 353 patients who satisfied the inclusion criteria,10%were admitted to the intensive care unit(n=36)and 7%died during the hospital stay(n=25).The median age was 40 years and 50.7%were male.On admission,49%had aspartate transferase-dominant liver injury.On admission,APRI(>0.5 and≤1.5)was independently associated with all-cause in-hospital mortality in unadjusted regression analysis and after adjustment for age and sex;after stepwise adjustment for several clinically relevant confounders,APRI was still significantly associated with all-cause inhospital mortality.On admission,APRI(>0.5 and≤1.5)increased the odds of mortality by fivetimes(P<0.006).From these results,we developed a new predictive model,the APRI-plus,which includes the four predictors of age,aspartate transferase,platelets,and serum ferritin.Performance for mortality was very good,with an area under the receiver operating curve of 0.90.CONCLUSION APRI-plus is an accurate and simplified prediction model for mortality among patients with COVID-19 and is associated with in-hospital mortality,independent of other relevant predictors.

文摘Background:The development and prognosis of breast cancer are intricately linked to psychological stress.In addition,depression is the most common psychological comorbidity among breast cancer survivors,and reportedly,Fang-Xia-Dihuang decoction(FXDH)can effectively manage depression in such patients.However,its pharmacological and molecular mechanisms remain obscure.Methods:Public databases were used for obtaining active components and related targets.Main active components were further verified by ultra-high-performance liquid chromatography-high-resolution mass spectrometry(UPLC-HRMS).Protein–protein interaction and enrichment analyses were taken to predict potential hub targets and related pathways.Molecule docking was used to understand the interactions between main compounds and hub targets.In addition,an animal model of breast cancer combined with depression was established to evaluate the intervention effect of FXDH and verify the pathways screened by network pharmacology.Results:174 active components of FXDH and 163 intersection targets of FXDH,breast cancer,and depression were identified.Quercetin,methyl ferulate,luteolin,ferulaldehyde,wogonin,and diincarvilone were identified as the principal active components of FXDH.Protein–protein interaction and KEGG enrichment analyses revealed that the phosphoinositide-3-kinase–protein kinase B(PI3K/AKT)and Janus kinase/signal transducer and activator of transcription(JAK2/STAT3)signaling pathways played a crucial role in mediating the efficacy of FXDH for inhibiting breast cancer progression induced by depression.In addition,in vivo experiments revealed that FXDH ameliorated depression-like behavior in mice and inhibited excessive tumor growth in mice with breast cancer and depression.FXDH treatment downregulated the expression of epinephrine,PI3K,AKT,STAT3,and JAK2 compared with the control treatment(p<0.05).Molecular docking verified the relationship between the six primary components of FXDH and the three most important targets,including phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha(PIK3CA),AKT,and STAT3.Conclusion:This study provides a scientific basis to support the clinical application of FXDH for improving depression-like behavior and inhibiting breast cancer progression promoted by chronic stress.The therapeutic effects FXDH may be closely related to the PI3K/AKT and JAK2/STAT3 pathways.This finding helps better understand the regulatory mechanisms underlying the efficacy of FXDH.
文摘Objective: The aim of present study was to determine the frequency of depression and anxiety among tuberculosis patients. Methods: It was a descriptive study that had investigated the co-morbidity of depression and anxiety among tuberculosis patients with reference to gender. This study was conducted in Jinnah Post Graduate Medical Centre—Chest ward (TB clinic) from July 2014 to September 2014. Hundred diagnosed patients of tuberculosis (50 males and 50 females) were randomly selected. Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Questionnaire (GAD-7) were used to assess the level of anxiety and depression. Results: Findings indicated that 56% tuberculosis (TB) patients had moderate to severe level of depression, whereas 65% TB patients had moderate to severe level of anxiety. Female patients had significantly high prevalence of depression as compared to males (t = –2.173, P –3.468, P Conclusion: Likelihood of depression and anxiety was frequent in tuberculosis patients. However, better management of these psychiatric morbidities may improve treatment adherence, illness perception and patient coping skills.
文摘BACKGROUND: This study aims to evaluate the results of studies investigating neutrophilto-lymphocyte ratio(NLR) and to identify the prognostic and diagnostic value of NLR in occlusive vascular diseases.METHODS: With the aim of identifying the studies related to NLR, a search was performed on http://www.ncbi.nlm.nih.gov/pubmed by using the key words "neutrophil lymphocyte ratio" between January 2005 and December 2014. All of the original articles were evaluated according to date of publications, countries, clinics and topics. Studies about occlusive vascular diseases were evaluated according to their qualifications, review methods and results. SPSS for Windows 16.0 was used in data analysis and data were expressed as mean, standard deviation and percentage.RESULTS: A total of 735 original research articles were investigated. The number of publications have shown a regular logarithmic increase over the years. Thirty-two percent of all publications were performed by clinics in Turkey and 56.4% were performed by general-oncological surgery and cardiology clinics. A total of 107 publications were identified to be about occlusive vascular diseases, 80.3% of these publications were found to be prognostic and 19.6% to be diagnostic, 82.2% of them were found to be planned as retrospective and 17.7% as prospective. In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.
文摘A 77-year-old man on systemic chemotherapy against postoperative bilateral multiple lung metastases of malignant solitary fibrous tumor of the pleura suffered from pruritus and jaundice. Blood examination showed elevated levels of hepatobiliary enzymes. Abdominal computed tomography showed a tumor with peripheral enhancement in the pancreatic head, accompanied with the dilatation of intra- and extra-hepatic bile ducts. He was diagnosed as having obstructive jaundice caused by a pancreatic head tumor. The pancreatic head tumor was presumably diagnosed as the metastasis of malignant solitary fibrous tumor of the pleura, because the findings on the pancreatic head tumor on abdominal CT were similar to those on the primary lung lesion of malignant solitary fibrous tumor of the pleura. The pancreatic tumor grew rapidly after the implantation of metallic stent in the inferior part of the common bile duct. The patient died of lymphangitis carcinomatosa of the lungs. Autopsy revealed a tumor that spread from the pancreatic head to the hepatic hilum. Microscopically, spindle-shaped cells exhibiting nuclear atypicality or division together with collagen deposition were observed. Immunohistochemically the pancreatic head tumor cells were negative for staining of α-smooth muscle actin （α-SMA） or CD117, but positive for vimentin, CD34 and CD99. These findings are consistent with those on malignant solitary fibrous tumor of the pleura. We report the first case of obstructive jaundice caused by a secondary pancreatic tumor from malignant solitary fibrous tumor of the pleura.
文摘Background: Distinguishing tuberculous pleural effusion (TPE) from other causes of exudative effusion is often challenging. Delay in treatment initiation can occur while awaiting histo-microbiologic confirmation owing to the paucibacillary nature of the disease. Sago-like nodules are the most common visual finding on gross thoracoscopic appearance. The primary objective was to determine the diagnostic utility of the presence of sago-like nodules on gross thoracoscopic appearance in TPE to help justify early initiation of tuberculosis (TB) treatment based on their finding while awaiting final histo-microbiologic confirmation. Secondary objective was to study the correlation between the presence of sago-like nodules and the final histo-microbiologic findings in pleural biopsy specimens. Methods: This was a retrospective-descriptive study of all patients with exudative pleural effusion who underwent diagnostic medical thoracoscopy (MT) at Hamad General Hospital during an eight-year period (from January, 2008 to December, 2015). Results: The presence of sago-like nodules on gross thoracoscopic appearance of the pleural surface had a sensitivity of 58%, a specificity of 89% and a positive predictive value of 97% for TPE with a diagnostic accuracy of 62%. There is significant association between the presence of sago-like nodules and demonstration of granulomatous inflammation in pleural biopsy specimens (P = 0.000). There is no association between sago-like nodules and positive TB smear and culture in biopsy specimens. Conclusion: The presence of sago-like nodules on gross thoracoscopic appearance has a high specificity and positive predictive value for TPE and significantly correlates with the presence of granulomatous inflammation. Patients from TB prevalent areas with exudative pleural effusion and sago-like nodules on gross thoracoscopic appearance may be commenced on TB chemotherapy while awaiting final histologic confirmation.
文摘Background/Aim: Although numerous prognostic factors have been described for non-small cell lung cancer (NSCLC), there is still a requirement for better and non-invasive markers. FDG-PET is a non invasive diagnostic tool that is being used increasingly in the diagnosis of lung cancer. This study evaluates the prognostic values of PET/CT defined SUV measurements and other patient/tumor characteristics in newly diagnosed stage IIIB and IV NSCLC. Method: This ret- rospective study included 111 patients admitted between 2005 and 2006 with stage IIIB and IV NSCLC, whose diag- noses were verified with biopsy and staging performed with PET/CT. The prognostic values of standart uptake values (SUV) of the primary lesion on PET/CT, and other patient/tumor characteristics were analyzed using survival analysis. Results: SUV was found to be unrelated with survival. Only the presence of distant metastasis, type of metastasis (bone, brain, or the contralateral lung) and the type of radiotherapy used (curative or palliative) were found to be related to survival. SUV values in epidermoid carcinoma were found to be significantly higher compared to adenocarcinoma (16.15 ± 7.18 and 12.32 ± 5.52, respectively, p = 0.021).Conclusion: Our findings do not support that SUV of the pri- mary lesion in inoperable NSCLC has a prognostic value with respect to survival. This condition may be explained by the inclusion of significantly advanced NSCLC patients who are known to have a low survival and a high mortality, and also the relatively small sampling size.

文摘AIM To explore the relationship between colonic secretory function and colonic motility.METHODS Using a rat model chronically implanted with intracerebroventricular(ICV) and cecal catheters, we validated the correlation between colonic secretion and colonic motor functions, as well as the role of ICV injection volume.RESULTS Compared to saline controls(5 μL/rat), ICV acyl ghrelin at 1 nmol/5 μL enhanced the total fecal weight, accelerated the colonic transit time, and increased the fecal pellet output during the first hour post-injection, while ICV des-acyl ghrelin at 1 nmol/5 μL only accelerated the colonic transit time. These stimulatory effects on colonic motility and/or secretion from acyl ghrelin and des-acyl ghrelin disappeared when the ICV injection volume increased to 10 μL compared with saline controls(10 μL/rat). Additionally, the ICV injection of 10 μL of saline significantly shortened the colonic transit time compared with the ICV injection of 5 μL of saline. The total fecal weight during the first hour post-injection correlated with the colonic transit time and fecal pellet output after the ICV injection of acyl ghrelin(1 nmol/5 μL), whereas the total fecal weight during the first hour post-injection correlated with the fecal pellet output but not the colonic transit time after the ICV injection of des-acyl ghrelin(1 nmol/5 μL).CONCLUSION Colonic secretion does not always correlate with colonic motility in response to different colonic stimulations. Acyl ghrelin stimulates colonic secretion.
文摘BACKGROUND Breast milk is the best and principal nutritional source for neonates and infants.It may protect infants against many metabolic diseases,predominantly obesity and type 2 diabetes.Diabetes mellitus(DM)is a chronic metabolic and microvascular disease that affects all the body systems and all ages from intrauterine life to late adulthood.Breastfeeding protects against infant mortality and diseases,such as necrotizing enterocolitis,diarrhoea,respiratory infections,viral and bacterial infection,eczema,allergic rhinitis,asthma,food allergies,malocclusion,dental caries,Crohn's disease,and ulcerative colitis.It also protects against obesity and insulin resistance and increases intelligence and mental development.Gestational diabetes has short and long-term impacts on infants of diabetic mothers(IDM).Breast milk composition changes in mothers with gestational diabetes.AIM To investigate the beneficial or detrimental effects of breastfeeding on the cardiometabolic health of IDM and their mothers.METHODS We performed a database search on different engines and a thorough literature review and included 121 research published in English between January 2000 and December 15,2022,in this review.RESULTS Most of the literature agreed on the beneficial effects of breast milk for both the mother and the infant in the short and long terms.Breastfeeding protects mothers with gestational diabetes against obesity and type 2 DM.Despite some evidence of the protective effects of breastfeeding on IDM in the short and long term,the evidence is not strong enough due to the presence of many confounding factors and a lack of sufficient studies.CONCLUSION We need more comprehensive research to prove these effects.Despite many obstacles that may enface mothers with gestational diabetes to start and maintain breastfeeding,every effort should be made to encourage them to breastfeed.

文摘The coronavirus disease 2019(COVID-19)pandemic affects all countries and populations worldwide,significantly impacting people with autism with a high risk of morbidity and mortality due to COVID-19.Approximately 25%of children with autism have an asymptomatic or symptomatic immune deficiency or dysfunction.In addition,they frequently have various comorbid conditions that increase the severity of COVID-19.In addition,severe COVID-19 during pregnancy may increase the risk of autism in the offspring.Furthermore,severe acute respiratory syndrome coronavirus 2 could target human nervous system tissues due to its neurotrophic effects.The COVID-19 pandemic intensely impacts many patients and families in the autism community,especially the complex management of autism-associated disorders during the complete lockdown.During the complete lockdown,children with autism had difficulties coping with the change in their routine,lack of access to special education services,limited physical space available,and problems related to food and sleep.Additionally,children with autism or intellectual disabilities are more liable to be abused by others during the pandemic when the standard community supports are no longer functioning to protect them.Early detection and vaccination of children with autism against COVID-19 are highly indicated.They should be prioritized for testing,vaccination,and proper management of COVID-19 and other infectious diseases.In this review,we discuss the various effects of COVID-19 on children with autism,the difficulties they face,the increased risk of infection during pregnancy,how to alleviate the impact of COVID-19,and how to correct the inequalities in children with autism.
