Objectives: To investigate the role of procalcitonin (PCT) as a predictor of in-hospital mortality in patients with severe to critical COVID-19. Patients and Methods: In a retrospective cohort study, 150 patients with severe to critical COVID-19 consecutively admitted to the intensive care unit (ICU) were investigated. Patients’ demographics, clinical and laboratory findings, and PCT level were collected upon their admission to the hospital and from the disease outcome data. Results: Of the 150 patients who entered the study, 77 were discharged alive from the hospital. The mean age of the patients was 60.9 ±16.3 years and 51.3% of them were male. The mean PCT level was significantly higher in the deceased patients than in survivors (2.4 ± 3.4 versus 0.7±1.3, P<0.005). The logistic regression analysis indicated that PCT, creatinine and urea levels were independently associated with in-hospital mortality. Conclusion: Serum PCT levels are associated with in-hospital mortality in COVID-19 patients admitted to ICU and could be used as a simple tool to predict adverse outcomes and expedite timely and appropriate interventions.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86807768","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}

Objectives: According to the lack of a gold standard for definition of apoptosis, we conducted a pilot analysis to propose a new definition for apoptosis based on a previous gene expression data. Materials and Methods: As a secondary analysis, a gene expression data of a vitrification thawing induced model of apoptosis conducted on ten mice ovaries was used. Half of the samples had been treated with selenium. P53, Fas, Bax and Bcl2 were considered as apoptosis related genes. Their +∆CTs were reported. An apoptosis scoring system was designed based on regression analysis. Results: In multiple regression of the genes, the only significant association was for Bcl2 expression for prediction of apoptosis. Then a model was designed consisting of Bcl2 and some interactions that the calculated amount of its formula was considered as the scoring system (R2 = 0.989, P (>F) <0.001, Root mean square deviation = 0.082). Bax/Bcl2 ratio showed an acceptable goodness of fit for prediction of this score (R2 = 0.845, P (>F) <0.001, root mean square deviation = 0.219). No conclusive result was found for factor analysis. Conclusion: The present study used a simple approach to propose statistical models for apoptosis. A comprehensive criterion should be designed apoptosis and other biological systems to be considered as a gold standard.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76418733","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}

Objectives: The purpose of our study is to determine the prevalence and factors associated with AAC. Patients and Methods: This cross-sectional study including 40 chronic HD patients for more than six months having benefited from screening for AAC by profile abdominal x-ray without preparation. The AAC were evaluated according to the Kauppila score (ScK). Demographic, biological and radiological data were collected and then analyzed to assess the prevalence of AAC. Patients were divided into two groups according to ScK, highly calcified (ScK ≥12) and slightly or moderately calcified (ScK <12), in order to determine the associated factors to severe AAC. Results: The mean age was 58 ± 16 years, 55% were women, and the median of HD duration is 82 months. The prevalence of AAC was 65% and the median score of AAC was four. Patients with highly AAC (ScK ≥12) represented 27.5% of population and slightly or moderately AAC (ScK <12) represented 72.5%. The factors associated with severe AAC retained in the univariate analysis were age (P=0.029), phosphoremia (P=0.027), duration of dialysis (P=0.047) and calcemia (P=0.035). Only duration of dialysis (P=0.042), age (P=0.018) and phosphoremia (P=0.044) remained statistically significant in multivariate. Conclusion: AAC are associated with advanced age, long duration of dialysis, and phosphocalcic balance abnormalities. Profile abdominal x-ray without preparation is currently recommended by the KDIGO (kidney disease improving global outcomes) for early detection and follow-up of vascular calcifications on HD, which should be considered for any patient.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82453076","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}

{"title":"Administration of calcium and vitamin D supplementation in kidney stone formers","authors":"T. Soleymanian","doi":"10.15171/JPD.2018.23","DOIUrl":"https://doi.org/10.15171/JPD.2018.23","url":null,"abstract":"Nephrolithiasis is a common medical issue worldwide and it has an overall prevalence of 7% in women and 10.5% in men (1). It mainly affects active working age population and has high socioeconomic burden (2). Calcium comprises about 80%-90% of the kidney stones components as calcium oxalate and calcium phosphate, so that applying measures for reducing urine calcium excretion have increasingly been used (3). Calcium is absorbed by both active calcitriol-dependent and passive mechanisms in small bowel depending on the amount of daily consumption, and it ranges between 10% to 70% (4,5). It has been shown that kidney stone formers have higher fractional absorption of calcium in intestine leading to greater urinary calcium excretion (6,7). Multiple large studies have shown that calcium intake has a protective role against kidney stone formation by decreasing absorption of intestinal oxalate and subsequent decline in urine oxalate (8-10). Furthermore, Restriction of calcium intake not only would raise risk of oxalate absorption, it also has detrimental effect on bone mineral density which has already been lost in kidney stone formers (11). Therefore, moderate calcium intake of 800-1200 mg daily, mainly by calcium-rich diet or as supplementation taking with diet, is advocated for stone formers (12). It has been demonstrated that intake of calcium supplements both with and without meal increases urine calcium, but because of binding of dietary oxalate with calcium when it is taken with meal, the amount of intestinal oxalate absorption and its urine secretion declines and the rate of stone formation would not increase (13). Of note, apart from calcium intake in high amounts, several other dietary habits including low fluid intake, small intake of fruits and vegetable, large sodium intake, excessive consumption of diet rich in oxalate, and high meat intake are involved in stone formation (14). Therefore, patients who are taking calcium and vitamin D supplements should be advised to consider the foregoing predisposing factors of stone formation. Also, as several systemic diseases such as diabetes, obesity and hypertension are linked with stone disease (15,16), approaches for managing these conditions Implication for health policy/practice/research/medical education Taking recommended doses of supplemental calcium and vitamin D among nephrolithiasis patients have no significant consequence on kidney stone formation.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"38 1","pages":"74-75"},"PeriodicalIF":0.0,"publicationDate":"2018-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79644167","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}

In this study, they measured serum vitamin D levels in a group of Iranian healthy individuals (102 participants) to evaluate the relationship between serum 25-hydroxy vitamin D with gender and age of participants (1). The results of the study showed that vitamin D level is lower than 20 ng/mL in a significant percentage of healthy individuals (73%) which was considered as vitamin D deficiency. The levels of vitamin D in 18% of participants were between 20.1 to 29.9 ng/mL which were interpreted as a marginal deficiency. Therefore according to the results of this study, only 9% of the healthy individuals had normal vitamin D level and the prevalence of vitamin D deficiency among Iranian healthy individuals was alarming high (1). Similar to the results of Khazaei et al study, the results of other investigations which have performed in some other Asian countries like India and Pakistan showed that majority of people in these countries had severe vitamin D deficiency. As an example, Rasul Khan and colleagues evaluated vitamin D status in patients presenting with a complaint of easy fatigability at a medical outpatient clinic. They showed that 92% of participants had low vitamin D levels. Vitamin D status was in the normal range in only 8% of the patients in the study by Rasul Khan et al (2). A similar percentage (89.3%) of low vitamin D levels was also recorded from Northern Pakistan in the study by Mufti et al (3). Although some data from Saudi Arabia showed that the Saudi population has better vitamin D status as compared to the above studies, however the other data from Saudi Arabia also revealed that majority of the patients had low vitamin D levels (4). As an example, Mirza et al evaluated vitamin D status in individuals with body aches at an outpatient department in Dammam, Saudi Arabia Implication for health policy/practice/research/medical education The prevalence of vitamin D deficiency is alarming high in the world and therefore specialists and general physicians have to be more educated about the causes of vitamin D deficiency.","PeriodicalId":16657,"journal":{"name":"Journal of Parathyroid Disease","volume":"7 3 1","pages":"78-79"},"PeriodicalIF":0.0,"publicationDate":"2017-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91065765","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}
