Oral nifedipine versus intravenous labetalol for acute blood pressure control in hypertensive emergencies of pregnancy: a randomized controlled trial

Background: To compare intravenous labetalol with oral nifedipine in terms of rapidity at which they control blood pressure in acute hypertensive emergencies of pregnancy.Methods: A randomized controlled study. Pregnant women with severe gestational hypertension with BP ≥160/110 mmHg after ≥20 weeks of gestation were randomized with computer generated numbers, either to receive IV labetalol with an escalating dose of 20, 40, 80, 80 and 80 mg or nifedipine capsule orally in a dose of 10 mg every 15 minutes (upto 5 doses) until a BP of ≤150/100 mmHg is achieved. Crossover treatment was to be effected if initial treatment regimen was unsuccessful. Primary outcome was time taken and number of doses required to achieve the target BP of ≤150/100 mmHg. Secondary outcomes were volume of urine output, maternal heart rate changes, fetal heart rate abnormality, perinatal and maternal outcome and side effects.Results: Oral nifedipine achieved the target BP (≤150/100 mmHg) more rapidly in (26.25±12.60) minutes in comparison to (32.62±12.19) minutes with IV labetalol (p= 0.024). Nifedipine group also took less number of doses to achieve the target BP of (≤150/100 mmHg) mmHg than IV labetalol (1.75±0.840 vs. 2.18±0.83), p= 0.024. Volume of urine output was also significantly more in nifedipine group (94.90±1.84 ml) at 1 hour and thereafter till 24 hour of treatment in comparison to IV labetalol (41.28±2.14 ml), p= 0.000. Side effects are few and not serious. No patient required crossover treatment.Conclusions: Both the drugs are equally effective in controlling acute hypertensive emergencies of pregnancy, however oral nifedipine is more rapid in controlling severe hypertension and also it is associated with significantly increased urine output

Environmental and Health Impact of Small-Scale Gold Mining Activities in Ibanda District of Uganda

In the recent past, artisanal small-scale gold mining activities in Kicuzi Subcounty, Ibanda District, Uganda, have had a severe influence on the environment and people's health. The study investigated the environmental and health impacts of small-scale. The questionnaires of 156 respondents were given to the Ibanda District's surrounding areas. The findings demonstrated that p-value is substantially associated with perception and the surroundings (p < 0.0005). The finding also demonstrates that p-value is substantially connected with the environment and health (p< 0.0005). The findings revealed that diarrhoea, skin illness, and injuries are the most common ailments in the population. As can be observed from the results, 75% of health workers admit that the health system in this municipality is not equipped to deal with mining-related health issues

3D surface reconstruction from a single uncalibrated 2D image

This paper described a simple computation to reconstruct 3D surface using a single uncalibrated 2D image from a digital camera as an image acquisition device that also focused on fast processing. An object is placed on a table with black background for the digital camera to shoot an image of the object. Image segmentation methods are applied in order to obtain the shape of the object from silhouette. The concept Radon transform is adopted to generate sinograms of the object and it is then inverse Radon transform is used to construct 2D cross-section of the object layer by layer. Canny edge detection helps to get the outline of each cross-section and coordinate points are extracted forming 3D point cloud from the image slices. 3D surface of the object is then reconstructed using Delaunay triangulation to connect each point with another. The results obtained from this project are satisfying regarding the processing time with recognizable shape and also strengthened with considerably low percentage error in the calculation for all six objects used in the experiment

Prediksi Perubahan Garis Pantai Menggunakan Program GENESIS (Studi Kasus Pantai Kelapa Rapat)

Shoreline profile has a tendency to adjust the wave effect on the shoreline. Changes to the lineconsists of two kinds of erosion and sedimentation. Waves that can affect shorlines rise due to theinfluence of the wind, the wind blowing duration and distance without hurdles when the windblows (fetch). The waves were coming to cause the migration of sediment on the shoreline. Ifwaves erode sediment on the shoreline, shoreline will occur erosion and if the waves bring sedi-ment to the shoreline, on the shoreline sedimentation will occur. For example there is the KelapaRapat Beach (Pesawaran). On the beach, there is a highway a short distance away from theshoreline. Potential erosion will occur at the shoreline can cause breakdown of the resulting ero-sion of sediment on the shoreline. Due to the potential, then do research using GENESIS programto be able to estimate the extent of erosion potential disruption accessibility having an effect waycontained in about Kelapa Rapat Beach
