Abstract Some rapid statistical tests give (a) rapid answers on how well methods agree and control chart evaluation (sign and run tests) and (b) evaluation of distribution of test results (Tukey's quick test and run test). These tests mainly require counting of data and the use of the given nomograms. An unusual distribution of patient test values—that is, unusual when compared with the generally observed distribution of the data seen in a particular laboratory—may indicate laboratory error, alteration of specimens (as from poor collection and/or storage techniques, such as evaporation), or an unusual patient population.

Adherence To Therapy

Failure of therapy is a result of bad adherence  medication. Non-adherence to therapy is a major factor that is suspected to result in uncontrolled blood pressure in hypertensive patients resulting in more serious complications. Therefore it is important to increase the adherence rate of treatment in patients with hypertension in the treatment process. For this reason, the need for interventions to improve  adherence  with several aspects that can be changed. This study uses One Group Pretest-Posttest Design using 100 samples. Data derived from questionnaires containing 25 items of adherence to therapy, 5 items of knowledge, 4 items of trust, 3 items of motivation, 10 items of family support with nonparametric statistical tests used were Mc Nemar test. Mc Nemar test results indicate that there is a significant difference between adherence at the pre-test and at the post-test after counseling with a significance value (p = 0,000). The results also showed that there was a difference in knowledge with a significance value (p = 0.001), motivation with a value (p = 0.031) and family support with a value (p = 0,000). The education with counseling about knowledge, trust, motivation and family support is effective in increasing compliance. There are other changeable factors such as lifestyle education, patient doctor relationships, and the use of smartphone applications for self-reported therapy can improve adherence in patients thereby minimizing therapy failure. Other educational methods that can be used besides counseling are counseling and dissemination of social media information.

The results of studies of the change in redox potential in the profile of light gray forest surface-gleyed soil on variants with long-term agricultural use without applying fertilizers and mineral fertilizer system solely compared with the soil under the forest are presented. On the basis of the conducted analyzes it was established, that soil tillage without fertilizer application and with mineral fertilizer solely has a different effect on ROP in the profile. In the soil without fertilization (control) as compared to the forest a moderate oxidizing (514 mV) and slightly oxidizing (437 mV) processes are happening. Prolonged application of mineral fertilizers to the soil (N65R68K68) significantly reduced the redox potential of all genetic horizons compared with forest and control without fertilizers. For the given fertilizer system the highest values of ROP were obtained in arable HEgl and underarable HEgl layers: 426 mV and 416 mV respectively. Redox potential sharply decreases with the depth to 398-311 mV, which characterizes processes occurring in the soil profile, as weakly reducing and close to moderately reducing.

The Nordic countries are often considered as remarkably exceptional in terms of the proenvironmental behavior of their citizens and also as forerunners in environmental policies. However, very few empirical studies have been done at the aggregated level about how the Nordics compare to other countries. The article addresses this knowledge gap and analyzes the Nordic region in terms of willingness to make economic sacrifices, proenvironmental attitudes and behaviors. Data (N = 5877) from the environment module of the International Social Survey Program (ISSP) are utilized, with nonparametric statistical tests and multinomial logistic regression employed—wherein, emphasis is placed on the regression models for willingness as dependent variables as analysis of the first order, with attitudes, behaviors and sociodemographic variables as part of second order analysis. The findings reveal that the region’s higher levels of willingness, attitudes, and behaviors become more salient when compared to third countries. People in the Nordic region who are ‘neither willing nor unwilling’ to protect the environment can be considered as distinct, and should not be arbitrarily lumped within the categories of the ‘unwilling’ or ‘willing’ respondents. These insights allow for a deeper understanding of peoples’ willingness and the relationships to respective attitudes and behaviors beneficial towards engaging the acceptability of extant environmental policies.

Abstract Objectives Many women in recent years have been willing to undergo puncture surgery for childbirth, which, like other surgeries, has physical and psychological side effects such as incision, infertility, chronic pain, and anxiety. Therefore, it is important to reduce and improve these side effects. The aim of this study was to determine the effect of foot massage with orange essential oil on pain and anxiety in women undergoing cesarean section. Methods This randomized clinical trial study was conducted in 2019 on 80 women referred to Bahar Shahroud Hospital after cesarean section surgery. The samples were divided into two groups by intervention (foot massage with orange essential oil) and control (foot massage without orange essential oil). The Spielberger scale was used to determine anxiety scores after cesarean section. In the intervention group, the feet were massaged with orange essential oil, and in the control group, the orange essential oil massage was performed without oil. Anxiety before, immediately after, and 60 min after the intervention was measured and evaluated in both groups. Data analysis was performed using descriptive and inferential statistics. Significant levels were considered for all statistical tests (p<0.05). Results The anxiety score before the intervention in the two groups of intervention and control was 57.12 ± 3.12 and 57.07 ± 3.54, respectively, which were not significantly different, but immediately after the intervention, the anxiety scores in both groups decreased significantly so that there was a further decrease in the intervention group (52.10 ± 4.75 and 56.02 ± 3.77), 1 h after the intervention, the anxiety score in the intervention group decreased compared to the previous stage and increased in the control group (50.40 ± 3.74 and 56.85 ± 4.27). Conclusions Foot massage with orange essential oil can probably be effective as a proper nursing intervention in reducing anxiety after cesarean section surgery.

Sperm Separation

A prospective, multicenter, randomized, sibling oocyte study was conducted with 86 couples to evaluate if a microfluidic sperm separation device improved ICSI sperm selection and subsequent cycle outcomes of fertilization, blastocyst utilization, ploidy, and clinical pregnancy rate when applied to a general patient population. Patients with at least 10 metaphase II oocytes were enrolled in the study and sibling oocyte groups were split in half. One half of the oocytes underwent ICSI with the control processed sperm and the other half were injected with sperm sorted by the ZyMōt microfluidic sperm separation device. Fertilization rate was recorded and resulting blastocysts were biopsied and evaluated for ploidy status with NGS. Euploid, non-mosaic embryos were randomly selected for single embryo transfer. A total of 787 oocytes were evaluated in the ZyMōt group and 777 in the control group. No statistical differences were observed between ZyMōt and control processing methods in any of the study outcomes evaluated. It is possible that the selection of normal, progressive sperm for ICSI, and the repair capacity of oocytes are sufficient to promote normal embryonic development in the general infertility population.

AbstractPrednisolone is used for treatment of inflammatory, allergic, neoplastic, and immune-mediated diseases in dogs. As a glucocorticoid, prednisolone has biochemical effects, which may interfere with the interpretation of biochemistry test results. The aim of this study is to investigate the effects of prednisolone treatment in an anti-inflammatory dose on common biochemical analytes in dogs and to evaluate the clinical relevance of the changes. Ten beagle dogs, enrolled in a cross-over study, were treated with oral prednisolone (1 mg/kg 24 h) for 10 days. Blood samples were collected at day 0, 1, 3, 6, 9, 10, 12, 16, and 20. Data was analyzed using a general linear model with time and treatment as fixed factors. Pairwise comparisons were done between prednisolone and control period for each dog and sampling. Significant results were further evaluated for clinical relevance using laboratory-specific reference intervals and reference change values (RCVs), when available. Statistically significant changes were observed for ALP activity and iron concentration, which increased to levels exceeding the RCV, and several results were outside reference intervals. Phosphate and bile acids increased significantly, while amylase, lipase, and cholesterol decreased significantly, but with mean/median results remaining within reference intervals. Anti-inflammatory prednisolone treatment did not induce significant changes in ALT, GLDH, GGT, cPLI, glucose, or calcium. Treatment with an anti-inflammatory dose of prednisolone induced changes in several analytes. Only the increases in ALP and iron were of such magnitude that they are expected to affect the clinical interpretation of test results.
