| 3 | Esophageal squamous cell cancer in a highly endemic region显示文摘AIM: To identify risk factors associated with esophageal cancer in Zambia and association between dietary intake and urinary 8-iso prostaglandin F2α(8-iso PGF2α).METHODS: We conducted a prospective, case control study at the University Teaching Hospital. Subjects included both individuals admitted to the hospital and those presenting for an outpatient upper endoscopy. Esophageal cancer cases were compared to age and sex-matched controls. Cases were defined as patients with biopsy proven esophageal cancer; controls were defined as subjects without endoscopic evidence ofesophageal cancer. Clinical and dietary data were collected using a standard questionnaire, developed a priori. Blood was collected for human immunodeficiency virus(HIV) serology. Urine was collected, and 8-iso PGF2α was measured primarily by enzyme-linked immunosorbent assay and expressed as a ratio to creatinine.RESULTS: Forty five controls(mean age 54.2 ± 15.3, 31 male) and 27 cases(mean age 54.6 ± 16.4, 17 males) were studied. Body mass index was lower in cases(median 16.8) than controls(median 23.2), P = 0.01. Histopathologically, 25/27(93%) were squamous cell carcinoma and 2/27(7%) adenocarcinoma. More cases smoked cigarettes(OR = 11.24, 95%CI: 1.37-92.4, P = 0.02) but alcohol consumption and HIV seropositivity did not differ significantly(P = 0.14 for both). Fruit, vegetables and fish consumption did not differ significantly between groups(P = 0.11, 0.12, and 0.10, respectively). Mean isoprostane level was significantly higher in cases(0.03 ng/mg creatinine) than controls(0.01 ng/mg creatinine)(OR = 2.35, 95%CI: 1.19-4.65, P = 0.014).CONCLUSION: Smoking and isoprostane levels were significantly associated with esophageal cancer in Zambians, but diet, HIV status, and alcohol consumption were not. | Akwi W Asombang Violet Kayamba Mpala M Lisulo Kathryn Trinkaus Victor Mudenda Edford Sinkala Stayner Mwanamakondo Themba Banda Rose Soko Paul Kelly | 2016 | World Journal of Gastroenterology2016，22，9： | 2 |

| 7 | Prevalence and burden of gastrointestinal helminths in wild and domestic guineafowls (Numida meleagris) in the Southern Province of Zambia显示文摘Objective: To determine the gastrointestinal tract helminthic fauna in domestic and wild guineafowl in Zambia.Methods: Post-mortem and laboratory parasitological examinations for helminth identification and enumeration were conducted on 198 guineafowls(148 domestic and 50 wild) from November 2010 to October 2011.Results: All guineafowls were infested with one or more helminths. Eleven helminth species, namely, Raillietina echinobothrida, Raillietina tetragona, Raillietina cesticillus, Ascaridia galli, Allodapa suctoria, Gongylonema ingluvicola, Tetrameres spp., Heterakis spp., Acuaria spiralis, Syngamus trachea, and Streptocara pectinifera were identified with no trematodes recorded. Mean nematode burden between domestic and wild fowl showed no differences having 113.7 [confidence interval(CI) 98.9-128.6] and 108(CI 76.6-139.5) nematodes respectively. In contrast, female guineafowls had a mean of 151.9(CI 128.4-177.8) nematodes per host which was significantly more than the males that had a mean of 79.6(CI 66.8-94.4). However, there were differences in helminth species richness between domestic and wild guineafowls with domestic guineafowls having more species present at a mean of 4.2(CI 3.91-4.44) than the wild ones at a mean of 3.4(CI 2.92-3.88) but there were no sex differences. Eight of the eleven helminth species co-occurred in domestic and wild fowl and five of the helminth species had higher prevalence in domestic guineafowls.Conclusions: Syngamus trachea, Streptocara pectinifera and Acuaria spiralis are reported for the first time in domestic poultry in Zambia. This study represents the first comparative study of helminths in domestic and wild guineafowls at an interface area and adds to the knowledge base in a discipline where a dearth currently exists. | King Shimumbo Nalubamba Eugene Chisela Bwalya Ntombi Basimbi Mudenda Hetron Mweemba Munangandu Musso Munyeme David Squarre | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，8： | 0 |
| 8 | Could China’s journey of malaria elimination extend to Africa?显示文摘World Health Organization (WHO) certified China malaria-free on June 30, 2021, which brightens the goal of global malaria elimination efforts. China contributed its unique innovations to the global community: Artemisinin, discovered by Tu Youyou, has saved millions of lives globally;the “1-3-7” norm developed in 2012, has been adapted in the local contexts of countries in the Southeast Asia and Africa. How to the targets of Global Technical Strategy for Malaria (GTS) 2016−2030. By looking into the malaria control phase, towards elimination phase from 1960 to 2011 in sub-Saharan Africa and China, we found that the gap in malaria burden will widen unless the interventions in Africa are enhanced. It is imperative to identify the key China–Africa cooperation areas on malaria control and elimination, so that synergized efforts could be pooled together to help African countries achieve the elimination goal. The practices from China malaria control and elimination efforts could be leveraged to fast-track malaria elimination efforts in Africa, which makes it possible that the China’s journey of malaria elimination extends to Africa. | Duoquan Wang Shan Lv Wei Ding Shenning Lu Hongwei Zhang Kokouvi Kassegne Shang Xia Lei Duan Xuejiao Ma Lulu Huang Roly Gosling Joshua Levens Salim Abdulla Mutinta Mudenda Moses Okpeku Kenneth Kamwi Matengu Potiandi Serge Diagbouga Ning Xiao Xiao-Nong Zhou | 2022 | Infectious Diseases of Poverty2022，11，3： | 0 |
| 9 | 急慢性绒毛膜羊膜炎与围生期人免疫缺陷病毒-1传播风险显示文摘Objective: This study was undertaken to examine the prevalence of acute and chronic chorioamnionitis among women infected with human immunodeficiency virus-1 (HIV-1) and to determine the relative contribution of each to perinatal HIV-1 transmission. Study design: In 227 HIV-infected women receiving intrapartum/neonatal nevirapine prophylaxis, we examined associations between fetal membrane histology, cord blood interleukin-6 (IL-6), and perinatal HIV-1 transmission. Results: Acute chorioamnionitis was present in 122 of 227 specimens; chronic chorioamnionitis in 64 of 227. There was a positive correlation between acute chorioamnionitis and labor length (r = 0.208; P = .002), time of ruptured membrane (r = 0.177; P = .008), and cord IL-6 (r = 0.390; P < .001). Chronic chorioamnionitis was associated with high viral load (P = .05) and low cord IL-6 (P < .001). Severe chronic chorioamnionitiswas associated with intrauterine HIV-1 transmission (odds ratio [OR] = 7.61; 95%CI = 1.04-85.5), but no correlation was demonstrated between acute chorioamnionitis and vertical transmission. Conclusion: In a setting of high perinatal nevirapine use, acute chorioamnionitis was not associated with vertical HIV-1 transmission. Risk for intrauterine transmission increased significantly when chronic chorioamnionitis was present. | Mudenda V. Levy J. 李奎 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，0，4： | 0 |
