Management of univentricular defects is performed gradually; bidirectional cavopulmonary shunt (BCPS) is one of the surgical approaches conducted before the definite treatment in the Fontan procedure. Therefore, the average rate of pulmonary artery pressure and vasculature resistance is critical factors in determining good post-surgical outcomes. However, studies exploring the evidence that sildenafil administration can reduce pulmonary pressure in patients with univentricular defects are currently limited. AIM: This evidence-based case report aims to investigate whether sildenafil administration toward post-BCPS patients reduces mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) before undergoing the Fontan procedure. METHODS: Available evidence was screened through four databases in PubMed, Cochrane, Embase, and ProQuest on October 9, 2022. The keywords used were (((((single Ventricle) OR univentricular heart) AND BCPS) OR Glenn) AND sildenafil) AND hemodynamic. A result of three cohorts and one clinical trial was identified and critically appraised. RESULTS: Analytical testing of the two studies by Park I and Jeremiasen et al. shows that sildenafil significantly reduces mPAP from 19.5 ± 5.5 mmHg to 14.3 ± 3.0 mmHg (p = 0.023) and from 19 mmHg (SD = 3) to 14 mmHg (SD = 2) (p < 0.01). The studies from Hill KD and Mori et al. illustrate that sildenafil significantly reduces the PVR index by as much as 24% (p < 0.01) and from 3.2 ± 0.5 wood unit to 1.6 ± 0.6 wood unit (p < 0.0001). CONCLUSION: The administration of sildenafil decreases pulmonary artery pressure and vasculature resistance in post-BCPS pediatric patients, allowing patients to undergo the Fontan procedure.","PeriodicalId":19562,"journal":{"name":"Open Access Macedonian Journal of Medical Sciences","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135675215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AIM: This study aimed to examine the incidence of transition shock among newly employed nurses. METHODS: A total of 43 newly employed nurses fill out the questionnaire Environmental Reality Shock-Related Issues and Concerns to assess transition experience, stress self-assessment, support, and job satisfaction. The Mann–Whitney and Kruskal–Wallis tests were applied to determine the difference in the level of transition shock according to the sociodemographic variables, stress-self-assessment, and job satisfaction and support. RESULTS: A significant difference in the level of transition shock was recorded in the length of waiting for employment in the expectation (p = 0.020), and private life factor (p = 0.026), the intention to leave the profession in the relationship (p = 0.016), and expectation factor (p = 0.044). The level of transition shock was different with regard to dealing with stress (p = 0.047), job satisfaction (p = 0.027), and the level of support from colleagues (p = 0.012), and superiors (p = 0.026). CONCLUSION: The lower job satisfaction, lower support, and weaker coping with stress of newly employed nurses increase the transition shock during the 1st year. These results can be useful for managers of health institutions to plan specific activities aimed at reducing the level of transition shock, especially at this time of pronounced shortages of nurses worldwide.","PeriodicalId":19562,"journal":{"name":"Open Access Macedonian Journal of Medical Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135189664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MATERIALS AND METHODS: Sixty extracted single-rooted mandibular premolars were collected and divided into three main groups according to the rotary system used (n = 20). Each tooth was impeded in a resin block, coded, sectioned, and photographed under a stereomicroscope, before and after instrumentation. Microphotographs were analyzed using AutoCAD software. Two-way ANOVA was used to evaluate the mean percentage of the touched surface and mean cross- sectional area between the groups and tooth segments, followed by Tukey’s post hoc test for pair-wise comparisons. RESULTS: The percentage of touched canal walls was significantly different between IRace group and each of XP-endo Shaper and HyFlex CM groups (p < 0.001). A statistically significant difference was recorded for the mean change in the cross-sectional areas of the root canal between IRace group and both HyFlex CM and XP-endo Shaper groups, respectively (p < 0.001). For all groups, there was a significant difference in the change in the cross- sectional area between all segments (coronal, middle, and apical). CONCLUSIONS: Within the limitations of this study, the XP-endo Shaper and HyFlex CM files had a higher cutting efficiency and maintained better root stability than the IRaCe system by preserving the dentin of the oval root canal. This was observed at all the canal levels in the coronal, middle, and apical segments.","PeriodicalId":19562,"journal":{"name":"Open Access Macedonian Journal of Medical Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135423179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MATERIALS AND METHODS: Twelve male mongrel dogs were used in the experiment and divided into two equal groups, group I, control group, group II, dogs with alloxan-induced diabetes. The dogs of the group II were injected by fresh preparation of a single dose of 100 mg/kg body weight of alloxan monohydrate dissolved in physiological saline. Ten days later, blood glucose level was determined using enzymatic colorimetric test; dogs presented a glucose level at or above 200 mg/dL were included in the diabetic group of the experiment. Three months later, dogs were sacrificed and the parotid glands from all groups were dissected and prepared for histological examination and double immunohistochemical expression of both actin and proliferating cell nuclear antigen (PCNA). RESULTS: Histological findings using H and E staining confirmed that the parotid gland parenchyma of the diabetic group had glandular atrophy characterized by loss of normal gland structure, acinar degeneration, and dilatation of the duct system with the presence of duct like structure. Moreover, there was a predominance of the fibrous component with the presence of fat cells within the gland compartments. Immunohistochemical findings of parotid gland of control group revealed positive scattered actin staining of weak to mild quantity in cells embracing some acini and intralobular ducts. Expression of PCNA in actin-positive cells revealed few scattered reactions embracing some acini and small ducts. Parotid gland of diabetic dogs revealed positive actin staining of mild-to-moderate quantity in the cells encircling the acini, intralobular, and some interlobular ducts. Expression of PCNA in actin- positive cells revealed mild-to-moderate positive reaction more concentrated in the cells surrounding both acini and intercalated ducts. CONCLUSION: Routine histological findings of diabetic dogs in our findings showed abundant pathological changes in parenchymal tissue elements, including acinar, ductal, and MECs that had a significant impact on saliva production and secretion resulting in dry mouth. The proliferative activity of MECs in the control group indicated a routine regeneration process, whereas the abundant proliferative activity in the diabetic group might indicate pathological transformation rather than regeneration, especially because no remedial measures were taken during this investigation.","PeriodicalId":19562,"journal":{"name":"Open Access Macedonian Journal of Medical Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135528610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
