While severe illness is not common among children and young individuals, a particular type of severe condition called multisystem inflammatory syndrome in children (MIS-C) has been reported. The aim of this prospective cohort study, which followed a group of individuals under the age of 19, was to examine the characteristics of patients who had contracted SARS-CoV-2, including their coexisting medical conditions, clinical symptoms, laboratory findings, and outcomes. The study also aimed to investigate the features of children who met the WHO case definition of MIS-C, as well as those who required intensive care. A total of 270 patients were included between March 2020 and December 2021. The eligible criteria were individuals between 0-18 with a confirmed SARS-CoV-2 infection at the Infectious Disease Hospital “Prof. Ivan Kirov” in Sofia, Bulgaria. Nearly 76% of the patients were ≤ 12 years old. In our study, at least one comorbidity was reported in 28.1% of the cases, with obesity being the most common one (8.9%). Less than 5% of children were transferred to an intensive care unit. We observed a statistically significant difference in the age groups, with children between 5 and 12 years old having a higher likelihood of requiring intensive care compared to other age groups. The median values of PaO2 and SatO2 were higher among patients admitted to the standard ward, while the values of granulocytes and C-reactive protein were higher among those transferred to the intensive care unit. Additionally, we identified 26 children who met the WHO case definition for MIS-C. Our study data supports the evidence of milder COVID-19 in children and young individuals as compared to adults.

In addition, it is still under debate whether the net effect is favorable or unfavorable for the fracture risk. Therefore, we conducted a cross-sectional study. Aim To assess the correlation between bone mineral density and fracture risk with insulin resistance and circulating insulin levels in non-diabetic postmenopausal women. Materials and methods The study analyzed 84 women. The mean age of the participants was 60.54 ± 7.07 years, and the mean postmenopausal period was 11.45 ± 6.62 years. A standard oral glucose tolerance test was performed with measurement of blood glucose and insulin levels at 0 and 120 min. Dual-energy X-ray absorptiometry was used to determine bone mineral density at lumbar spine and proximal femur. Fracture risk was calculated using the Fracture Risk Assessment Tool. Results We found that in non-diabetic postmenopausal women lower basal insulin levels (fasting insulin) were associated with a higher 10-year risk of major osteoporotic fracture when insulin sensitivity was preserved (HOMA-IR index < 2). Fasting insulin levels under 6.15 μIU/ml were considered high-risk regarding the fracture risk. On the other hand, higher stimulated insulin levels at 120 min (post-load insulin) were associated with a higher 10-year risk of major osteoporotic fracture at HOMA-IR index greater than 2. Stimulated insulin levels above 39.7 μIU/ml were considered high-risk regarding the fracture risk. Conclusion Our results revealed a negative relationship between stimulated insulin levels at HOMA-IR index above 2 and bone integrity in postmenopausal age. On the other hand, higher basal insulin levels at HOMA-IR index lower than 2 were associated with better parameters of postmenopausal bone health.","PeriodicalId":35746,"journal":{"name":"Acta Medica Bulgarica","volume":"50 1","pages":"26 - 32"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42563003","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}

Aims This study aimed to assess the prevalence of depression among the specified groups of workers and to identify the main stressors that lead to symptoms of this condition. Materials and methods A self-administrated questionnaire was completed by respondents comprised of three groups of workers in the Republic of North Macedonia – Skopje. The survey assessed the sociodemographic characteristics and mental health (Patient Health Questonnaire-9). Logistic regression models were used to estimate associations between depressive symptoms and demographics, working environment and lifestyle parameters. Results The analysis of the total PHQ-9 score divided into two groups (≤ 10 and ≥ 10) indicated that 89% of the respondents had minimal/mild depression and 11% had moderate/severe depression. We have found a significant association between the group to which the respondent belongs and the degree of depression. Severe depression was significantly associated with work in public institutions. Conclusion Screening for depression among workers is necessary because of its high prevalence and high rates of underdiagnosis in the workplace. Early diagnosis and appropriate interventions are recommended, including actions focused on the risk factors for depression at the workplace.","PeriodicalId":35746,"journal":{"name":"Acta Medica Bulgarica","volume":"50 1","pages":"42 - 48"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42233817","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}

The herb is characterized by a high content of polyphenols among which is fustin. The anticancer activities of fustin, however, are extremely weakly studied. The aim of the present study was to investigate the in vitro antiproliferative potential of fustin isolated from the heartwood of C. coggygria against cell lines originating from two of the most common cancer types – breast (MDA-MB-231 and MCF7), and colon cancer (Colon 26). Materials and methods Cell growth inhibitory properties of fustin were examined by MTT assay. Subsequently, phase-contrast and fluorescence microscopy analysis as well as colonyforming assay were carried out on the most sensitive to the cytostatic action of the fustin cell line. Results The obtained results showed that fustin reduced the proliferation of all studied cell lines. The highest cytostatic effect was registered towards breast cancer MDA-MB-231 cells with a half maximal inhibitory concentration (IC50) value of 56.02 μg/ml followed by colon cancer cells with an IC50 of 78.07 μg/ml. MCF7 cell proliferation was least affected with a calculated IC50 of 187.8 μg/ml. Further investigations on breast cancer MDA-MB-231 cells indicated decreased density of cell monolayer and some morphological alterations, significant attenuation in the number of viable cells, and diminished clonogenic ability of cells after fustin exposure. Conclusion It could be concluded that fustin isolated from the heartwood of medicinal plant C. coggygria possesses marked antiproliferative properties against breast cancer cell line MDA-MB-231 which will be a subject of our more detailed future investigations.","PeriodicalId":35746,"journal":{"name":"Acta Medica Bulgarica","volume":"50 1","pages":"27 - 33"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48841090","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}

The classical supplementation with calcium and active vitamin D may represent a challenge to the clinician. Objective To describe the level of biochemical control in patients with chronic hypoPT and to look for differences between postsurgical and non-surgical cases referred between 2006 and 2020. Materials and Methods This was a retrospective cross-sectional study with data review from the database of a tertiary endocrine clinic from the last 15 years. Cases with hypocalcemia not related to PTH were excluded. The patients’ medical history was reviewed as well as concomitant diseases and medications. Serum calcium (total, albumin-corrected and ionized; sCa, corrCa, iCa+) and phosphates (P), magnesium, creatinine, alkaline phosphatase together with 24hr urinary calcium and phosphate were measured. The intact parathyroid hormone (iPTH) was determined by electro-hemi-luminescence (Elecsys, Roche Diagnostics). Thyroid and abdominal ultrasound (US) were both performed. Results Seventy-eight patients met the study criteria – 69 were females. Most of them were between 30 and 60 years (mean age 50.6 ± 14.5 years). Albumin-corrected calcium was in target in 20.5% of the patients, ionized calcium – in 36.5%, serum phosphate – in 46.3%, serum magnesium – in 87.9%. When all four parameters were taken together, less than 20% were in target. Hypercalciuria was registered in 11.8%, while 57.1% of the patients had nephrolithiasis and 27.3% had CKD grade 3-4. Thus, a high proportion of patients with kidney involvement was identified. Calcium carbonate and calcitriol were the preferred replacement choices. Comparing patients with post-surgical and non-surgical hypoPT significant differences were found only for age, total serum calcium, serum magnesium and TSH. Conclusion Our study is the first of its kind in our country during the last two decades describing the contemporary clinical and biochemical picture of chronic hypoPT in patients referred for specialized care. Low supplementation doses leading to hypocalcemia and hyperphosphatemia were a common finding. Low patient’s adherence may be just one possible explanation. Non-surgical cases tend to have even lower calcium and magnesium levels. The patients, their families and treating physicians should be better informed about up-to-date management of chronic hypoPT and the possible impact of suboptimal treatment on morbidity and mortality of the affected subjects.","PeriodicalId":35746,"journal":{"name":"Acta Medica Bulgarica","volume":"50 1","pages":"5 - 12"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43357399","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}

This could lead to sudden death or severe aortic regurgitation and cardiogenic shock. The presented case here describes a patient with acute anterior ST-elevation myocardial infarction due to acute Stanford type A ascending aortic dissection. Case presentation A 55-year-old male presented with severe chest pain, radiating into the back, jaw, and left arm, and signs of cardiogenic shock. Electrocardiography showed acute anterior ST-elevation myocardial infarction and echocardiography confirmed that there was a reduced left ventricle ejection fraction (38% calculated using the Simpson method), severe aortic regurgitation, and wall motion abnormalities. Based on these findings, we made a diagnosis of acute myocardial infarction. In accordance with the current guidelines, we opted for an interventional therapeutic approach. Angiography showed left main trunk dissection extending to the left anterior descending coronary artery caused by ascending aorta dissection. This finding altered the diagnosis and treatment plan and the patient was immediately sent to the operating room for emergency surgery. Conclusions Aortic dissection should be suspected in patients presenting with acute anterior ST-elevation myocardial infarction, severe aortic regurgitation, and cardiogenic shock. Involvement of the left main trunk and left anterior descending artery occurs much more rarely than that of the right coronary artery, which causes inferior myocardial infarction.","PeriodicalId":35746,"journal":{"name":"Acta Medica Bulgarica","volume":"50 1","pages":"67 - 71"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45312174","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}

The goal of surgery is to resect all tumours with negative histological margins while preserving sufficient functional hepatic parenchyma and reducing postoperative complications. The use of Indocyanine green (ICG) for liver function assessment and fluorescence image-guided surgery could be used to achieve that goal. Clinical Case Description We present the case of a 62-year-old female patient with diagnosed sigmoid colon cancer with four bilobar liver metastases who underwent a simultaneous sigmoid resection and ICG fluorescence image-guided liver resection 3 days after preoperative ICG liver function assessment. We decided to perform liver-sparing resection having in mind the liver metastases’ number, size and location and the slightly impaired liver function (ICG retention rate 15 – ICGR15 was 14,02%). All liver tumours were removed without complications, and the resected margins were all microscopically free of tumour tissue (R0 resection). The postoperative period was uneventful, without any signs of postoperative liver failure. Conclusions ICGR15 can be considered a safe and informative marker for liver function and indirectly for the degree of portal hypertension. ICG fluorescence provides an additional method to assist intra-operative tumour identification.
