INTRODUCTION: Human anatomy is one of the fundamental pillars of basic medical sciences, which forms the cornerstone of the ever-evolving medical practice. It is, therefore, important to strengthen anatomy education at all stages of medical training. Since 2020, the Department of Human Anatomy, in collaboration with the Department of Surgery, organized surgical anatomy dissection courses to improve surgical practice safety and competence. This educational study aimed to share lessons learned from organizing anatomy dissection courses and measure the impact on knowledge and skills acquisition by surgical trainees. METHODS: Courses were designed with clear learning objectives and programs. A pre-test was administered to trainees before the dissection course, and a post-test was organized at the end of the course. Descriptive statistics were used to compare pre- and post-test scores. A p-value less than 0.05 was considered statistically significant. The Likert scale was used to measure trainees’ satisfaction at the end of every course.RESULTS: From August 2020 to December 2021, 11 cadaveric dissection courses were organized, and 173 trainees from 6 Surgical Residency programs: Plastic surgery, General surgery, Orthopedic surgery, Urology, Neurosurgery, ENT, and Obstetrics and Gynecology. Nineteen trainers from the Surgery Department and Anatomy Department were involved.There was a significant improvement in marks in the post-test test as compared to the pre-test score. The average increase in the mark was 26.4% with a 95% CI [23-0 – 29.7], p-value < 0.001. There was a negative correlation (r=-0.8948, p-value < 0.001) between the marks at pre-test and the improvement score, suggesting that the lowest performers on the pre-test had the biggest post-test improvement. Trainees’ satisfaction was at a high level. 87.6% of trainees reported a desire to pursue training to become anatomy educators in the future. CONCLUSION: Surgical anatomy dissection courses positively impacted surgical knowledge and skills acquisition, integrating anatomy into surgical training. Cadaver-based surgical procedures simulation should be encouraged and integrated into surgical curricula.

Tropical forests store 40–50 per cent of terrestrial vegetation carbon 1. However, spatial variations in aboveground live tree biomass carbon (AGC) stocks remain poorly understood, in particular in tropical montane forests 2. Owing to climatic and soil changes with increasing elevation 3, AGC stocks are lower in tropical montane forests compared with lowland forests 2. Here we assemble and analyse a dataset of structurally intact old-growth forests (AfriMont) spanning 44 montane sites in 12 African countries. We find that montane sites in the AfriMont plot network have a mean AGC stock of 149.4 megagrams of carbon per hectare (95% confidence interval 137.1–164.2), which is comparable to lowland forests in the African Tropical Rainforest Observation Network 4 and about 70 per cent and 32 per cent higher than averages from plot networks in montane 2,5,6 and lowland 7 forests in the Neotropics, respectively. Notably, our results are two-thirds higher than the Intergovernmental Panel on Climate Change default values for these forests in Africa 8. We find that the low stem density and high abundance of large trees of African lowland forests4 is mirrored in the montane forests sampled. This carbon store is endangered: we estimate that 0.8 million hectares of old-growth African montane forest have been lost since 2000. We provide country-specific montane forest AGC stock estimates modelled from our plot network to help to guide forest conservation and reforestation interventions. Our findings highlight the need for conserving these biodiverse 9,10 and carbon-rich ecosystems.

Background Anemia among Women of Reproductive Age (WRA) continues to be among the major public health problems in many developing Rwanda where It was increased comparing 2015 to 2010 Demographic and Health Survey (DHS) reports. A thorough understanding of the its risk factors is necessary to design new better approaches. However, to the best of our knowledge, no study assessing factors associated with anemia among WRA has been conducted. Therefore, this study aims to identify anemia risk factors among WRA in Rwanda. Methods This was a quantitative, cross-sectional study using secondary data from the Rwanda Demographic and Health Survey (RDHS) 2014-2015. The study population consisted of 6680 WRA who were tested for anemia during the survey. Anemia was defined as having equal or below to 10.9 g/dl for a pregnant woman, and hemoglobin level equal or below to 11.9 g/ for a non-pregnant woman. Pearson’s chi-squared test and multiple logistic regression were conducted for bivariate and multivariable analysis respectively. We reported Odds Ratio (OR), 95% Confidence Intervals (CI) and p-values. We used Stata version 14.2 for all analyses. Results The prevalence of anemia among WRA was 19.2% (95% CI: 18.0 - 20.5). After controlling for other variables, the factors associated with were being obese (OR: 0.61, 95% CI: 0.40 - 0.91), being in rich category (OR: 0.74, 95% CI: 0.63 - 0.87), sleeping under a mosquito net (OR: 0.85, 95% CI: 0.74 - 0.98), and using hormonal contraceptives (OR: 0.61, 95% CI: 0.50 - 0.73). The factors associated with higher odds of anemia were being underweight (OR: 1.39, 95% CI: 1.09 - 1.78), using an Intra Uterus Device (OR: 1.98, 95% CI: 1.05 - 3.75), and living in the Southern province (OR: 1.45, 95% CI: 1.11 - 1.89) or in the Eastern province (OR: 1.41, 95% CI: 1.06 - 1.88). Conclusion Anemia continues to pose public health challenges; novel public health interventions should consider geographic variations, improve women economic status, and strengthen iron supplementation especially for IUD users. Additionally, given the association between anemia and malaria, interventions to prevent malaria should be enhanced.
