Lampit is one of the traditional means of cultivating rice fields, which functions to level the land for planting rice. The operation of lampit can increase the work pulse up to 50% above the resting pulse and is included in the category of moderate to heavy workloads. At the end of the operation of lampit, it may cause complaints, especially on the buttocks and back, which is caused by the small and hardness of the lampit rod. There was an improvement to the lampit seating design by adding foam pads and adjusting the pressure lever found on the lampit stem to overcome this problem. This research is an experimental study using the same subject design, selected 30 research subjects from farmers in Dusun Semaja Antosari Tabanan Bali. The workload is evaluated based on the work pulse measured using the ten pulses method. In addition, the pulse was measured before and after the improvement of the lampit design. The data compared were the mean values before and after improvement, which were analyzed using paired t test (α = 0.05). The result is a significant decrease in the work rate of 19.35% (p <0.05). Thus, it can be concluded that the improved design of the lampit can reduce the workload. Therefore, farmers should continue using and perfecting the improved lampit.

Background: Dengue Hemorrhagic Fever (DHF) in Indonesia is a “re-emerging infectious disease”. DHF can be prevented by vector control. Human behavior is very influential on dengue vector control, namely the cleanliness of the house and activities. In 2017, DHF cases in Indonesia were 59,047 cases. In North Sumatra Province, there were 5,327 cases, in Medan City as many as 1216 cases, with Medan Deli District as the sub-district with the most cases, with 100 cases. Objective: This study aims to see the improvement of mother's behavior by using the roleplay method and simulation games. Methods: The research is a quasi-experimental non-equivalent group design. The target population is mothers who live in Medan Deli District. The selection of research subjects by purposive sampling, with the number of subjects in each group is 15 people. This study uses the method of role play and games as a comparison method, with a questionnaire as a measuring tool. Paired t-test to see the increase in the mean of each group, and unpaired t-test to see the difference in the mean value. Results: The results of the paired t-test data analysis found that these two methods showed significant results, with p values ​​of 0.000 and 0.001 with a mean increase in the role play method of 1.40 and the game method of 1.53. The unpaired t-test was found to have a significant difference between the average post-test scores between the role play method and the game method, the mean post-test score for the role-play method was found to be lower than the post-test score for the game method. Conclusions: Counseling using the role play method and games provides significant results in increasing maternal behavior about DHF. The game method shows a greater average increase than the role play method.

There is a lack of accurate three-dimensional studies to locate malar prominence for specified population, this study aims to locate the malar prominence using stable landmarks using CBCT. To derive a novel method to accurately locate the malar prominence and to assess and compare the malar prominence between males and females among Bangalore population using 3D CBCT study. All CBCT scans of study subjects belong to Bangalore population were collected from the pre-existing data available in Radiology imaging Solutions (CBCT centre), Bangalore during the period of September 10th to October 10th 2020. This is a descriptive study. A total of 42 subjects including 21 Males and 21 females were assessed using full skull CBCT scans which were converted to DICOM format and reconstructed into 3D images using NEMOCEPH 3D software. Landmarks used to locate the malar prominence were Fzs, Z, Zm and Ans. The intersection of these landmarks is considered to be as constructed maxillozygion(My). For the accuracy of the constructed Maxillozygion point (My), the distance between the actual Maxillozygion (Mzy) and constructed Maxillozygion (My) is measured and calculated between left and right halves of males and females. Three Orthogonal planes constructed were Midsagittal, Axial and Coronal Planes and the linear measurements with reference to all three reference planes in both the groups are measured. Student paired t- Test, Independent Student t Test, Mann Whitney Test. The mean distance from Mzy and my between right and left half of the face was compared using student paired t- Test. There is no significant difference (p=0.35).The mean values of the constructed anatomical landmark (maxillozygion) coordinated to three orthogonal planes between right and left sides of the face is compared using student paired T test and for both the genders (males and females) was compared using Independent Student t Test, and it is significantly higher in males as compared to females and it is statistically significant at (p=0.01). The location of malar prominence using CBCT by a novel method for Bangalore population is found which can be helpful in diagnosis and treatment planning for malar augmentation, camouflage treatment in subjects with midface deficiencies.

Abstract Introduction: Expiratory flow increase is a maneuver of respiratory physical therapy that promotes flow direction to the upper airways however, when applied in newborns, it may result in changes of thoracoabdominal mobility. Objective: To evaluate the thoracoabdominal mobility by photogrammetry in newborns after expiratory flow increase technique. Methods: Experimental blind study performed with newborns in supine position on a support table with upper limbs flexed, abducted and externally rotated and hip flexed at 110°. Adhesive markers were allocated for geometric delimitation of the thoracoabdominal compartment and expiratory flow increase technique was performed for 5 minutes with the therapist’s hands on the thorax and abdomen. Newborns were filmed before and after the maneuver and the frames were analyzed in AutoCAD® software by a blinded investigator at the time of the procedure. The largest and the smallest thoracoabdominal area were expressed in cm2 and the mean values were compared between two moments (pre and post maneuver) by paired t test. Results: Twenty newborns with a mean age of 39 weeks were included. Before the maneuver, thoracoabdominal area was 56.1 cm2 during expiration and 59.7 cm2 during inspiration, and after the maneuver the value was 56.2 cm2 during expiration and 59.8 cm2 during inspiration, with no statistical difference between before and after (p = 0.97, p = 0.92, respectively). Conclusion: Results demonstrate that expiratory flow increase technique does not seem to change thoracoabdominal mobility of healthy newborns.

Background: Gestational trophoblastic disease encompass a spectrum of neoplastic disorders that arise from placental trophoblastic tissue after abnormal fertilisation. Most molar pregnancies spontaneously resolve after uterine evacuation with no further sequelae. However, at any time during or after gestation malignant transformation may occur in approximately 10% to 20% of molar pregnancies. Quantification of βHCG is considered as the ideal method of post molar surveillance. The regression of the disease could be reliably assessed by observing the changes in low resistance flow which paralleled the gradual decrements in serial βHCG levels. To correlate uterine artery blood flow characteristics to serum βHCG levels in the follow up of patients with gestational trophoblastic disease after molar evacuation.Methods: 50 patients with gestational trophoblastic disease after evacuation were followed up by serum βHCG titres and Doppler ultrasonography of uterine arteries. The relationship between the Doppler indices and the serum βHCG titres were evaluated by paired –t test and Pearsons correlation analysis.Results: Significant negative correlations were observed between Systolic/Diastolic (S/D) ratios, Resistance Indices(RI) and Pulsatility indices (PI) and the absolute values of serum βHCG levels, with correlation coefficients of -0.5, -0.46 and -0.40 (p<0.01). The mean values of βHCG showed a decreasing trend from 1st week to 4th week. The mean value of RI, PI and S/D Ratio showed an increasing trend from 1st week to 4th week. However, the difference in mean values of βHCG and Doppler indices at 1st week and 4th week were analysed by paired t test and found to be statistically insignificant(p>0.05) in patients with spontaneous remission.Conclusion: Uterine artery Doppler indices can be used as an adjunct to βHCG for the surveillance of patients with gestational trophoblastic disease after molar evacuation to predict remission of the disease.

Purpose: Many studies comparing the morphology of native radial head with the prosthesis have been published. However, there is limited information regarding the postoperative alignment of the articular surface following the radial head replacement. The purpose of this study is to evaluate the alteration of the end-plane angle in the modular radial head prosthesis with a press-fit cementless cylindrical stem. Methods: The study used 36 cadaveric radii. The press-fit size prosthesis with cylindrical stem was inserted into each specimen. The end-plane angles of the radial head before and after prosthetic replacement, were measured in coronal and sagittal planes with a digital inclinometer. The data were analyzed by paired t-test. Results: From paired t-test, there were statistically symmetrical end-plane angles before and after radial head replacement in both coronal and sagittal planes (p-value < 0.01). The mean of radial head end-plane angle alteration in the coronal plane was 3.62° (SD, 2.76°) (range, 0.3°–8.9°). In the sagittal plane, the mean of alteration was 5.85° (SD, 3.56°) degrees (range, 0.3° – 14.2°). Conclusion: The modular radial head prosthesis with cylindrical stem is in vitro able to restore the native end-plane angles of radial heads statistically when used in a press-fit fashion.

Background Determining the extent of damage in vascular avulsion type injuries still represents a challenge for the microsurgeon. Excision of the damaged section is critical for the success of anastomosis. The purpose of this study was to determine which among vascular endothelial and adventitia damage findings is most effective in determining the extent of avulsion injury. Methods Varying degrees of avulsion were applied to the aorta of 12 (n = 12) adult female New Zealand rabbits. Avulsion was first determined using adventitial findings and then with endothelial findings. The definitive extent of damage was determined histopathologically. Results The mean area of the histopathological sections was 16.7 ± 6.9 mm. The extent of damage measured from the adventitia was 15.8 ± 7.9 mm (the difference in histopathological examinations was not significant, p = 0.590, paired t-test), while the extent of damage from the lumen was 13.3 ± 8.2 mm (the difference in histopathological examinations was significant p = 0.004, paired t-test). Conclusion Excision based on adventitia findings is more effective in case of avulsion injury.

Abstract Introduction: Paraproteins cause interference in many assays systems due to increased viscosity and/or by non-specific binding to either analytes or reagents which may variably affect the results. There is abundant evidence to indicate that performance characteristics of automated, competitive protein-binding assays for folate assays are normally sound, but there is a paucity of data comparing folate assays in patients with paraproteinaemia compared to normals. Method: Serum samples were prepared from venous blood taken into Greiner Vacuette containers (code: 456018) in fifty patients with paraproteinaemia (IgG Kappa, n = 20: IgG Lambda, n = 9: IgM Kappa, n = 6: IgM Lambda, n = 4: IgA Kappa, n = 5: IgA Lambda, n = 3: multiclonal, n = 3). Serum folate assays were measured according to manufacturer’s instructions on Beckman-Coulter Access and Abbott Architect haematinics analysers on the day of sample collection. Results: The ratio of means of serum protein concentrations in the paraprotein sub-groups compared to the mean values of age/gender related reference ranges were: IgG = 1.57: IgM = 7.8: IgA = 6.3. Serum albumin concentration was normal in all patients. Mean serum folate results (±1SD) for paraprotein patients and normals controls (laboratory personnel) are shown in the table below: Serum Folate (μg/L) Access Architect paired t-test Normal controls (n = 50) 5.98 (±3.57) 5.01 (±3.14) p&lt;0.05 Paraprotein patients (n = 50) 5.08 (±2.79) 5.01 (±3.03) p0.700 When analysed using the paired-t-test serum folate was significantly different in normal subjects using the Access compared to the Architect. However, no such significant difference between the two systems was observed in the paraproteinaemia group. Although the mean serum folate in normals was higher compared to the paraprotein group as analysed by the Access, this difference was not significant when analysed using the two-sample t-test. Interestingly the mean serum folate when analysed in the two groups using the Architect gave identical mean values. There were no statistically significant differences between the two methods in any of the paraprotein sub-types (p&gt;0.05 in each case). Conclusions: The complex and variable mixture of proteins present in paraproteinaemias pose potential erroneous measurement in immunoassay systems. This is because they may interfere with the associated antigen-antibody reactions which are dependant on complimentary matching shapes being assumed by the antibody variable regions of the immunoglobulin. Despite this, our data using two distinct chemiluminescence analysers for folate measurement indicate no statistically significant difference for this parameter between patients with paraproteinaemia compared to normal controls. However, it has yet to be determined whether differing results between these two groups are generated using different analytical techniques.
