Abstract This investigation was carried out in the frames of the Interreg 4A project “Workability and Social Inclusion” headed by the Arcada University of Applied Life. Tallinn University of Technology and Rīga Stradiņš University were involved in the project. A questionnaire based on the Nordic, WAI (Work Ability Index), and Kiva questionnaires was compiled to study psychosocial and physical working conditions at computer-equipped workplaces for 192 workers. The results showed that the computer workers assess their health status considerably high. They are optimistic in solving the problem that the monotonous work with computers will continue and believe that their health status in the future will stay at the same level using the steadily enhancing rehabilitation means. The most injured regions of the body were the right wrist and the neck. The novelty of the study consists in the graphical co-analysis of different groups of questions presented to the workers, which allows to assess the physiological and psychological factors in complex. The rehabilitation means have to be developed and the possibility for rehabilitation must be made available to the greatest possible number of workers. The workers were divided into two groups: Group A, the length of employment with computers under 10 years (included) and Group B, having been working with computers over 10 years. These groups were found to differ in the perception of psychosocial risk factors at the workplace. Group B assessments for psychosocial working conditions were better than those of group A. In group B, employees appeared to be more afraid of losing their jobs and therefore they were not so demanding for the work atmosphere as in group A.

Background: Functional tricuspid valve regurgitation secondary to left-sided valve disease is common. DeVega repair is simple, but residual regurgitation with subsequent impairment of the right ventricular function is a concern. This study aims to compare tricuspid valve repair using DeVega vs. ring annuloplasty and their impact on the right ventricle in the early postoperative period and after six months. Methods: This is a prospective cohort study of 51 patients with rheumatic heart disease who underwent tricuspid valve repair for secondary severe tricuspid regurgitation. Patients were divided into two groups: group A; DeVega repair (n=34) and group B; ring annuloplasty repair (n=17). Patients were assessed clinically and by echocardiography before discharge and after six months for the degree of tricuspid regurgitation, right ventricular diameter and tricuspid annular plane systolic excursion (TAPSE). Results: Preoperative echocardiographic assessment showed no difference in left ventricular end-systolic diameter, end-diastolic diameter, ejection fraction and right ventricular diameter, however; group A had significantly better preoperative right ventricular function measured by TAPSE (1.96 ± 0.27 vs1.75 ± 0.31 cm; p=0.02). Group B had significantly longer cardiopulmonary bypass time (127.65 ± 13.56 vs. 111.74 ± 18.74 minutes; p= 0.003) and ischemic time (99.06 ± 11.80 vs. 87.15 ± 16.01 minutes; p= 0.009). Pre-discharge, there was no statistically significant difference in the degree of tricuspid regurgitation, but the right ventricular diameter was significantly lower in group B (2.66 ± 0.41 and 2.40 ± 0.48 cm; p=0.049). After six months of follow up, the degree of tricuspid regurgitation (p= 0.029) and the right ventricular diameter were significantly lower in the ring annuloplasty group (2.56 ± 0.39 and 2.29 ± 0.44 cm; p=0.029). Although there was a statistically significant difference in preoperative TAPSE, this difference disappeared after six months. Conclusion: Both DeVega and ring annuloplasty techniques were effective in the early postoperative period, ring annuloplasty was associated with lesser residual regurgitation and better right ventricular remodeling in severe functional tricuspid regurgitation than DeVega procedure after 6-months of follow up.

Abstract In order to quantitatively assess the effect of sample storage conditions on the body burden analysis of organic contaminants, a comparative analysis was carried out on the unionid mussel Elliptic complanata. The mussels were divided into two groups, each with distinct storage conditions, while Group A was kept in the freezer at −20°C, Group B was kept in the refrigerator for five days at 5°C. All the compounds present in the control were also present in Group B samples. Analysis of the organic contaminants in each of these two groups showed that for total PCB concentrations, the two treatments were not significantly different; however when compared individually 6 of the 13 PCB congeners showed significant differences. The observed differences were relatively small for individual PCB congeners (7.1 to 15.3%), higher for chlorobenzenes (10.5 to 36.4%), and yet higher for HCE (44.1%); the difference for HCE, although large is nevertheless not significant, even if only marginally so.

Abstract Background Repair of a perforated tympanic membrane (myringoplasty) can facilitate normal middle ear function, resist infection, and help re-establish normal hearing. Autogenous graft materials are the most popular graft materials used in myringoplasty because of their easy acceptability by the body. This study is conducted to compare between temporalis fascia graft and fascia lata graft in myringoplasty for patients with tubo-tympanic dry perforation. Results A total of 60 patients with persistent dry tympanic membrane perforation were included in our study during the period from January 2018 to May 2020. Patients underwent myringoplasty with temporalis fascia (30 patients as group A) or fascia lata (30 patients as group B). Patients were scheduled for follow-up visits concerning graft status, ear discharge, and audiograms. The mean postoperative air-bone gap in group A was 17.5 ± 4 after 1 month and 8.6 ± 6.9 after 3 months, while in group B, the mean postoperative air-bone gap was 17.6 ± 4.9 after 1 month and 9.4 ± 7.5 after 3 months. There was 90% success in graft uptake in group A, while there was 80% success in group B. Conclusion Using temporalis fascia is still the best and most trustworthy technique of myringoplasty compared to fascia lata graft. However, fascia lata can be a good alternative to temporalis fascia especially in cases of revision myringoplasty, ears having large perforation, or near-total perforation where the chances of residual perforation are high because of the limited margin of remnant tympanic membrane overlapping the graft.

Abstract Background This study aims at determining the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability. Methods Two critical-size defects (CSDs) were bilaterally trephined in the parietal bone of 36 adult Sprague-Dawley rats (18 males and 18 females); the left remained empty (group A), while the right CSD was filled with nHAp/CS scaffold (group B). Two female rats died postoperatively. Twelve, 11, and 11 rats were euthanized at 2, 4, and 8 weeks post-surgery, respectively. Subsequently, 34 specimens were resected containing both CSDs. Histological and histomorphometric analyses were performed to determine the FBR, calculated as [the sum of areas of newly formed bone in lateral and central regions of interest (ROIs)]/area of the original defect, as well as the Ost and the CD (Ost/mm2) in each ROI of both groups (A and B). Moreover, biodegradability of the nHAp/CS scaffolds was estimated via the surface area of the biomaterial (BmA) in the 2nd, 4th, and 8th week post-surgery. Results The FBR of group B increased significantly from 2nd to 8th week compared to group A (P = 0.009). Both the mean CD and the mean Ost values of group B increased compared to group A (P = 0.004 and P < 0.05 respectively). Moreover, the mean value of BmA decreased from 2nd to 8th week (P = 0.001). Conclusions Based on histological and histomorphometric results, we support that 75/25 w/w nHAp/CS scaffolds provide an effective space for new bone formation.

The purpose of this research was to conduct a comparative study to find out which setting performs better between students in the Co-educational Instruction setting and Students in the Single-gender Instruction set. In this research process, the researchers compared the performance of students who receive instruction in a single-gender classroom with the performance of other students who receive instruction in a co-educational classroom. The study population was 756 students of single and mixed-gender streams, classified into two groups (A & B). Out of this, one single-gender male class of 268 students (group A) and one COED class of 488 students (group B) were sampled from the Islamic University of Technology (IUT) in Bangladesh. The research adopted a quasi-experimental research design. The instruments used for data collection were the summative assessment of both groups' first and second-semester results that serve as test instruments. Frequency counts and the Arithmetic means were used for descriptive analysis. The independent sample t-test was used to test the hypotheses. Social learning theory emphasizes the importance of biological, social, and cultural impacts on human behavioral development and learning, especially on gender and genders specific traits and roles. Based on the analyses and interpretation of the data, the researcher found that male students perform better academically in single-gender classes, contrary to their academic performance when mixed with females in the same classes. Thus, single-gender instruction could be a more favorable environment for male students than a co-educational instruction environment.

ABSTRACT Necrotizing fasciitis is a life threatening condition that can be quickly spread through the flesh surrounding the muscle. The disease can be polymicrobial, or caused by group A beta hemolytic Streptococci, or by Clostridium spp. We present a case of a 7 years old girl, which was hospitalized in Children Infectious Diseases Department in a 7th day of chickenpox (hematic crusts all over the body), high fever, asthenia, vomiting, oligoanuria, and tumefaction, pain and functio lessa in the right thigh. In a very short time in the right thigh swelling, edema and congestion have increased gradually, and in the third highest middle thigh the ecchymotic areas appeared evolving towards bubbles and blisters which included the right thigh and calf. After excluding the diagnosis of thrombophlebitis was raised suspicion of necrotizing fasciitis. CT pelvic scan evidenced pelvic asymmetry by maximus and medium right gluteal muscles swelling with important inflammatory infiltrate extended laterally in the subcutaneous adipose tissue. In blood culture was isolated Eggerthella lenta, and from throat swab was isolated group A Streptococci. Treatment consists of a combination of antibiotics associated with intravenous immunoglobulin administration. Despite medical treatment evolution worsened and required transfer in a pediatric surgery department where emergent surgical debridement associated with intensive antibiotic therapy was done. After this intervention evolution was slowly favorable without major limb dysfunction. Polymicrobial necrotizing fasciitis is a severe disease, which if recognized early can have a favorable outcome.

The efficacy of pulmonary vein antral isolation for patients with prolonged sinus pauses (PSP) on termination of atrial fibrillation has been reported. We studied the right atrial (RA) electrophysiologic and electroanatomic characteristics in such patients. Forty patients underwent electroanatomic mapping of the RA: 13 had PSP (group A), 13 had no PSP (group B), and 14 had paroxysmal supraventricular tachycardia (control group C). Group A had longer P-wave durations in lead II than did groups B and C (115.5 ± 15.4 vs 99.5 ± 10.9 vs 96.5 ± 10.4 ms; P=0.001), and RA activation times (106.8 ± 13.8 vs 99 ± 8.7 vs 94.5 ± 9.1 s; P=0.02). Group A's PP intervals were longer during adenosine triphosphate testing before ablation (4.6 ± 2.3 vs 1.7 ± 0.6 vs 1.5 ± 1 s; P &lt;0.001) and after ablation (4.7 ± 2.5 vs 2.2 ± 1.4 vs 1.6 ± 0.8 s; P &lt;0.001), and group A had more complex electrograms (11.4% ± 5.4% vs 9.3% ± 1.6% vs 5.8% ± 1.6%; P &lt;0.001). Compared with group C, group A had significantly longer corrected sinus node recovery times at a 400-ms pacing cycle length after ablation, larger RA volumes (100.1 ± 23.1 vs 83 ± 22.1 mL; P=0.04), and lower conduction velocities in the high posterior (0.87 ± 0.13 vs 1.02 ± 0.21 mm/ms; P=0.02) and high lateral RA (0.89 ± 0.2 vs 1.1 ± 0.35 mm/ms; P=0.04). We found that patients with PSP upon termination of atrial fibrillation have RA electrophysiologic and electroanatomic abnormalities that warrant post-ablation monitoring.

Introduction. To increase the effectiveness of social and hygienic monitoring of the health status of workers in harmful and/or dangerous occupation conditions by objectifying the analysis of the health status of workers and timely detection of premorbid forms of pathology, an informational medical advisory and diagnostic system is proposed that ensures the efficiency of using the previously developed methodological recommendations MR 2.2.9.0148-19 “Assessment of the risk of developing states of distress in workers in harmful working conditions”. Materials and methods. The design of the developed computer program is based on the principles of critical assessment of the employee’s health status; multiparametric characteristics of the functional reserves of the body; unity of the information base; the possibility of dynamic monitoring of the health status of employees; automation of data storage and analysis; protection of personal data. Results. The method used by the information system is based on a comprehensive assessment of the functional reserves of the body, correlated by the degree of adaptive stress, including the ranking of the employee health status according to the group of dispensary records, the indicator of adaptive compliance and the level of adaptive immunity. To facilitate the operator’s information support system integrated the List of harmful and (or) hazardous occupation factors, the presence of which is a mandatory preliminary and periodic medical examinations (surveys) and reference weight values, heart rate and blood pressure corresponding to the physiological norm concerning gender and age of the employee. Conclusion. The proposed information system can be used during periodic medical examinations to form risk groups for the development of occupational and production-related morbidity, as well as to assess the effectiveness of hygienic and therapeutic and preventive measures aimed at improving the health of workers in harmful occupation conditions.

Metabolism is the natural process of the body, which is necessary to maintenance of the homeostasis of an individual person. Everybody constitutions are always in the process of metabolism, which is a combination of Anabolism (Construction) and Catabolism (Deterioration). As Agni is prime factor for all the Chayapachayakriya. Medoroga, is one of the Metabolic disease, in which contributing factors are Agni, Ama along with Kaphapradhana Tridosha, Medodhathu. Due to various types of etiological factors, the Agni in the body gets vitiated and Jatharagnimandya occurs. By this Jatharagnimandya, Dhathuparinama will not occur properly. This will lead to Medoroga and further many other Upadravas. To correct these conditions, Ayurveda has many modes of therapies like Samshodhana, Samshamana. By these we can correct the metabolism from the root cause. Here 40 Subjects diagnosed with Medoroga w.s.r. to Hyperlipidemia fulfilling the Inclusion criteria were selected for study and randomly categorized into two groups as Group A and Group B each consisting of 20 subjects. For both groups Amapachana with Chitrakadi Vati, Sadhyosnehapana with Murchita Sarshapa Taila, Sarvanga Abhyanga with Murchita Tila Taila followed by Swedana. And Virechana was administered with Virechana Gulika. Than each group received two different Shamanoushadhi. So, the objective of the study is to establish the efficacy of Virechana along with Dashanga Guggulu and Virechana along with Shadushana Guggulu in the management of Medoroga.
