| 1 | Pro-and anti-inflammatory cytokines profiles among Nigerian children infected with Plasmodium falciparum malaria显示文摘Objective:To examine array of some pro- and anti-inflammatory cytokines,namely, interleukin-4(IL-4),interleukin-10(IL-10),interferon-γ(IFN-γ),interleukin-5(IL-5), interleukin-6(IL-6),interleukin-12(IL-12) and tumor necrosis factor-α(TNF-α) concentrations in some Nigerians with falciparum malaria.Methods:Sera were obtained from the blood samples of 96 Nigerian children with Plasmodium falciparum infection.The sera were subjected to cytokine evaluation using commercial standard enzyme linked immunosorbent assay kits(Abcam,UK).Results:Mean pro-inflammatory cytokines in serum of children with uncomplicated and complicated malaria were IL-5 482.2 pg/mL versus 526.7 pg/mL,IL-6 98.8 pg/mL versus 82.6 pg/mL,IL-12 24.1 pg/mL versus 15.9 pg/mL,TNF-α107 pg/mL versus 511.7 pg/mL and IFN- 7 2.1 pg/mL versus 2.5 pg/mL.The anti-inflammatory cytokines status of IL-4 were 4.7 pg/mL versus 20.3 pg/mL,and IL-10 were 216 pg/mL versus 143.8 pg/mL in uncomplicated versus complicated/severe malaria cases.Participants with uncomplicated malaria had mean parasitaemia level of 3 158.9 parasites/μL while mean parasitaemia level for participants with complicated malaria was 12 550.5 parasite/μL and this difference was statistically significant(χ~2 =5 614.6,P<0.05).The difference between mean haemoglobin level for uncomplicated malaria(9.6 g/dL) and severe malaria(3.9 g/dL) was statistically significant (χ~2 = 2.3,P<0.05).The relationship between serum level of IL-6,IL-12,IFN-γ,IL-10 and IL-4 and ages showed positive correlation at r=0.92,0.99,0.86,0.95 and 0.85,respectively;while IL-5 and TNF-αhad negative correlation at r=-0.99 and -0.99,respectively.Conclusion: IL-4,IL-5,IL-6,IL-10,IL-12,TNF-αand IFN-γare involved in the immunopathology and immunoregulation of uncomplicated and complicated malaria infections.IL-6,IL-12,IFN-γand IL-10 depressed in complicated/severe malaria may not provide any protective immunity and may be indicators of poor prognosis in Plasmodium falciparum infected Nigerian children. | Nmorsi OPG Isaac C Ukwandu NCD Ohaneme BA | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，1： | 2 |
| 2 | Diabetes mellitus, revascularization and outcomes in elderly patients with myocardial infarction-related cardiogenic shock显示文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients. | Miquel Gual Albert Ariza-Solé María García Márquez Cristina Fernández JoséL Bernal Francesc Formiga María-Isabel Barrionuevo JoséC Sánchez-Salado Victòria Lorente Júlia Pascual Isaac Llaó Oriol Alegre Angel Cequier Javier Elola | 2020 | Journal of Geriatric Cardiology2020，17，10： | 2 |
| 3 | Para-aortic lymph node involvement should not be a contraindication to resection of pancreatic ductal adenocarcinoma显示文摘BACKGROUND Para-aortic lymph nodes(PALN)are found in the aortocaval groove and they are staged as metastatic disease if involved by pancreatic ductal adenocarcinoma(PDAC).The data in the literature is conflicting with some studies having associated PALN involvement with poor prognosis,while others not sharing the same results.PALN resection is not included in the standard lymphadenectomy during pancreatic resections as per the International Study Group for Pancreatic Surgery and there is no consensus on the management of these cases.AIM To investigate the prognostic significance of PALN metastases on the oncological outcomes after resection for PDAC.METHODS This is a retrospective cohort study of data retrieved from a prospectively maintained database on consecutive patients undergoing pancreatectomies for PDAC where PALN was sampled between 2011 and 2020.Statistical comparison of the data between PALN+and PALN-subgroups,survival analysis with the Kaplan-Meier method and risk analysis with univariable and multivariable time to event Cox regression analysis were performed,specifically assessing oncological outcomes such as median overall survival(OS)and disease-free survival(DFS).RESULTS 81 cases had PALN sampling and 17(21%)were positive.Pathological N stage was significantly different between PALN+and PALN-patients(P=0.005),while no difference was observed in any of the other characteristics.Preoperative imaging diagnosed PALN positivity in one case.OS and DFS were comparable between PALN+and PALN-patients with lymph node positive disease(OS:13.2 mo vs 18.8 mo,P=0.161;DFS:13 mo vs 16.4 mo,P=0.179).No difference in OS or DFS was identified between PALN positive and negative patients when they received chemotherapy either in the neoadjuvant or in the adjuvant setting(OS:23.4 mo vs 20.6 mo,P=0.192;DFS:23.9 mo vs 20.5 mo,P=0.718).On the contrary,when patients did not receive chemotherapy,PALN disease had substantially shorter OS(5.5 mo vs 14.2 mo;P=0.015)and DFS(4.4 mo vs 9.8 mo;P<0.001).PALN involvement was not identified as an independent predictor for OS after multivariable analysis,while it was for DFS doubling the risk of recurrence.CONCLUSION PALN involvement does not affect OS when patients complete the indicated treatment pathway for PDAC,surgery and chemotherapy,and should not be considered as a contraindication to resection. | Rupaly Pande Shafiq Chughtai Manish Ahuja Rachel Brown David C Bartlett Bobby V Dasari Ravi Marudanayagam Darius Mirza Keith Roberts John Isaac Robert P Sutcliffe Nikolaos A Chatzizacharias | 2022 | World Journal of Gastrointestinal Surgery2022，14，5： | 2 |

| 5 | Schistosoma haematobium and Plasmodium falciparum coinfection with protection against Plasmodium falciparum malaria in Nigerian children显示文摘Objective:Malaria remains the single leading killer of children in sub - Sahara Africa and Schistosomiasis is considered to be second to malaria in global importance.Co - infection of malaria and urinary schistosomiasis has been reported to exacerbate disease morbidity such as anaemia.In different part of the globe,the co - infection between malaria and schistosomiasis provides some protections on the infected persons.The protective effect of this co - infection elucidated immunologically using cytokines is lacking in our locality.Methods:Urine and blood samples obtained from the 160 volunteers were subjected to standard parasitological techniques for diagnosis of urinary schistosomiasis and malaria respectively.Blood samples collected from these volunteers comprising 80 children with schistosomiasis and malaria and the 80 children who had malaria only were subjected to cytokines concentration determination using commercial standard enzyme linked immunosorbent assay kits(Abeam,UK).Results:Eighty participants with co - infection had a mean malarial parasitaemia of 662±201.1μL while the 80 participants with only P.falciparum malaria had a mean malarial parasiteamia of 5943±3270.7μL.Also the volunteers had mean haemoglobin of 11.2 g/dL for co - infected individuals and 5.7 g/dL for participants with single infection of malaria.The serum cytokine levels of the children with S. haematobium and P.falciparum and only P.falciparum infection are as follows;interleukin - 4(16.6 pg/ mL versus 5.2 pg/mL),IL - 5(501.3 pg/mL versus 357.5 pg/mL);IL -8(2 550 pg/mL versus 309 pg/mL),IL - 10(273 pg/mL versus 290 pg/mL),TNF -α(25 pg/mL versus 290 pg/mL) and IFN -γ(21.9 pg/mL versus 2.5 pg/mL).The TNF -α/IL - 10 ratio is 7 for the children with co - infection while those with only P.falciparum malaria infection had a TNF -α/IL - 10 ratio of 0.9.Conclusion:We conclude that the elevated IL - 4,IL - 5,IL - 8 and IFN -γconcentration induced by schistosomiasis altered the Th1/Th 2 profile and protected the children against the morbidity and severity of malaria attack among the children with co - infection. | Nmorsi OPG Isaac C Ukwandu NCD Ekundayo AO Ekozien MI | 2009 | Asian Pacific Journal of Tropical Medicine2009，2，2： | 2 |
| 6 | Anemia in patients with high-risk acute coronary syndromes admitted to Intensive Cardiac Care Units显示文摘Background Little information exists about the role of anemia in patients with acute coronary syndromes(ACS)admitted to Intensive Cardiac Care Units(ICCU).The aim of this study was to assess the prevalence of anemia and its impact on management and outcomes in this clinical setting.Methods All consecutive patients admitted to eight different ICCUs with diagnosis of non-ST segment elevation ACS(NSTEACS)were prospectively included.Anemia was defined as hemoglobin<130 g/L in men and<120 g/L in women.The association between anemia and mortality or readmission at six months was assessed by the Cox regression method.Results A total of 629 patients were included.Mean age was 66.6 years.A total of 197 patients(31.3%)had anemia.Coronary angiography was performed in most patients(96.2%).Patients with anemia were significantly older,with a higher prevalence of comorbidities,poorer left ventricle ejection fraction and higher GRACE score values.Patients with anemia underwent less often coronary angiography,but underwent more often intraaortic counterpulsation,non-invasive mechanical ventilation and renal replacement therapies.Both ICCU and hospital stay were significantly longer in patients with anemia.Both the incidence of mortality(HR=3.36,95%CI:1.43–7.85,P=0.001)and the incidence of mortality/readmission were significantly higher in patients with anemia(HR=2.80,95%CI:2.03–3.86,P=0.001).After adjusting for confounders,the association between anemia and mortality/readmission remained significant(P=0.031).Conclusions Almost one of three NSTEACS patients admitted to ICCU had anemia.Most patients underwent coronary angiography.Anemia was independently associated to poorer outcomes at 6 months. | Victoria Lorente Jaime Aboal Cosme Garcia Jordi Sans-Rosello Antonia Sambola Rut Andrea Carlos Tomas Gil Bonet David Vinas Nabil el Ouaddi Santiago Montero Javier Cantalapiedra Margarida Pujol Isabel Hernandez Maria Perez-Rodriguez Isaac Llao Jose C Sanchez-Salado Miquel Gual Albert Ariza-Sole 无 | 2020 | Journal of Geriatric Cardiology2020，17，1： | 2 |
