Objective: This retrospective study aimed to assess the risk factors associated with early implant failure using a multivariate logistic regressive model and generalized evaluating equations (GEE) analysis. A total of 892 patients who received 1931 dental implants within the period from 2015 to 2018 at Odonto-Maxillo-Facial Hospital, Ho Chi Minh City, Vietnam were included in this study. Several factors as age, gender, implant placement site, implant length and diameter, sinus lifting technique, the number of implants per patient, and implant brands were recorded. GEE analysis results showed that the implant-based failure rates were 6.1% after an observation period from 3 months to 3 years. Among 118 failed implants, 108 implants were lost before or at the abutment connection stage (91.5%). Male, maxilla implant placement and implant brands were identified as the risk factors for early implant loss. Implant brands which have significantly less early failure rates are Ritter, Nobel, MIS, Osstem, Neo.

Prevalence Of Anemia

BACKGROUND Anemia is a worldwide major problem known to affect people throughout the world. It has an adverse effect on both the social and economic development. The worldwide prevalence of anemia is 9% in developed nations. The global estimate indicates that 293.1 million of children under five years, approximately 43%, are anaemic worldwide and 28.5% of these children are found in sub Saharan Africa. In Zambia specifically Kasempa, no documented studies on prevalence have been done. Despite iron supplementation being given to pregnant women and the availability of blood transfusion. The burden of the disease remains high as determined by high mortality and morbidity. This study aims at determining the prevalence of anemia and the associated risk factors among under-five children at Mukinge Mission Hospital in Kasempa District. Knowledge of prevalence and the associated risk factors of anaemia will enhance early detection and timely management. OBJECTIVE 1.To determine the hemoglobin status of anaemia by its severity among anaemic under-five children admitted at Mukinge Mission Hospital. 2.To assess the association of anaemia with Malaria among under-five children admitted at Mukinge Mission Hospital. METHODS This was a retrospective study review of under-five children that were diagnosed and managed of Anemia at Mukinge Missions Hospital, over the period of period of 2015, 2017 and 2018. .Data of the variables of interest was extracted and analyzed using SPSS. RESULTS A sample population of 52 children was included in our study. The majority of the children were females 28 (53.8 %) and 24 (46.2 %) were Males. It was found that moderate and severe anaemia was 17.3% and 82.7 % respectively. Additionally, Majority of the anaemic children (75%) had Normocytic anaemia. The Pearson Chi square test revealed no statistical relationship between the variables; Malaria (p=0.58), Age (P=0.82), Gender (P=0.91). CONCLUSIONS According to our study, 39 (75%) had normal mean corpuscular volume which could suggest chronic diseases and sickle cell anemia. 11 (21.2%) had a low mean corpuscular volume indicating Microcytic anemia which could suggest diseases such as iron deficiency and thalassemia among many other causes. However, we were unable to determine the specific cause of anemia.
