Agroforestry system has been considered as one of the effective ways of the plantation for increasing a production and securing the environment as well as plays an important role in the social and economic development. Mindi development has been widely practiced in community forests but the agroforestry system is only limited to local knowledge obtained from old generation. This causes the people's forests to tend to be unable to survive due to the demands of the people's food needs. Arrowroot (Maranta arundinacea L.) had an important crop as a potential source of food and substitute for wheat flour and potential to be planted under Mindi trees (Melia azedarach L.) which had also potential as an alternative tree planting for the community forest. This research was aimed to 1) analyze the growth of Mindi trees and the productivity of arrowroot under mindi trees compared to monoculture system, 2) analyze the nutrient content of arrowroot under mindi trees compared to monoculture system. The experiment used a complete randomized design (CRD) with the agroforest under mindi trees and monoculture system as a factor. The result of growth in mindi showed that there is no significant difference in height, diameter, and canopy variable in agroforestry and monoculture plantation system while the root variable had significant difference among agroforestry and monoculture system. The physicochemical and nutrients content of arrowroot were diverse whereas there is no significant difference between the two system tested.Keywords: agroforestry, growth, productivity, fisikokimia, soil nutrient

Introduction. The prevalence of colorectal cancer in the world is increasing every year. In more than 40% of patients, the disease debuts with a clinical picture of acute intestinal obstruction, while in one third of cases the tumor is located in the right half of the colon. This leads to the necessity to perform colon resection or bypass surgery, the main stage of which is making entero- colic anastomosis. However, up to 15% of these anastomoses has a leakage. Development of methods of forming a reliable anastomosis is thus critical.Materials and methods. 37 patients with acute intestinal obstruction, divided into 2 groups (17 and 20 people), are included into the study. All of them, as a surgical stage of treatment, underwent a right hemicolectomy with the formation of an entero- colic anastomosis or a bypass surgery. A double-row side-to-side anastomosis was used in the comparison group, and a single-row “end-to-side” anastomosis in the main group (patent No. 2709253). The incidence of anastomotic leakage and mortality were assessed. Comparison was performed using Fisher’s exact test.Results. There were no cases of anastomotic leakage and mortality in the main group. In the comparison group, there were 5 leakages and 1 death.Discussion. When a modified entero-colic anastomosis is formed, adequate blood flow is maintained in the walls of the anastomosed intestinal loops, which contributes to adequate regeneration.Conclusion. The first clinical experience with the modified end-to-side entero- colic anastomosis is successful. It is planned to further recruit patients and study the features of the postoperative period.

Factors affecting outcome of decompressive hemicraniectomy in malignant middle cerebral artery infarction
Authors: Koirala Sagar , Bhandari Shreeram , Lohani Subash 
Published: September 2021

Introduction: Decompressive Hemicraniectomy (DHC) is a standard surgical management of malignant MCA (MMCA) infarction. This study was conducted to review the outcome of surgery and to find out factors associated with favorable outcomes at a tertiary level neurosurgery referral centre.
Methods and Materials: This is a retrospective study conducted over a period of three years from 2017 to 2019. Patient charts were reviewed for variable like age, sex, timing of surgery, GCS at presentation, length of ventilation, length of ICU admission and length of hospital stay. Primary outcome measure was GOSE: favorable (<=4) and unfavorable (>=5). SPSS version 23 was used for analysis.
Results: A total of 28 patients underwent DHC out of which 21 patients were available for analysis. Mean age of patients was 58.62 years. Mean GCS on arrival was 11.86. Mean interval duration between event and surgery was 51.88 hours. Mean duration of ventilation was 4.43 days. Mean length of ICU stay was 5.95 days. Mean hospital stay was 22.33 days. Mean GOSE was 2. Mean age was significantly lower in patients with favorable GOSE. Early surgery had better mean GOSE which was not significant statistically.
Conclusion: Patients with age less than 50 years have favorable GOSE despite MMCA infarction if decompressive hemicraniectomy is performed to accommodate brain swelling. Early surgery at presentation rather than waiting for deterioration might improve the outcome.
