Mortality Analysis

This data-based cohort consisted of 26,508 (7%) United States veterans out of the 399,290 who tested positive for SARS-CoV-2 from 1 March to 10 September 2020. We aimed to assess the interaction of post-index vitamin D (Vit D) and corticosteroid (CRT) use on 30-day mortality among hospitalized and non-hospitalized patients with coronavirus disease 2019 (COVID-19). Combination Vit D and CRT drug use was assessed according to four multinomial pairs (−|+, −|−, +|+, +|−). Respective categorical effects were computed on a log-binomial scale as adjusted relative risk (aRR). Approximately 6% of veterans who tested positive for SARS-CoV-2 died within 30 days of their index date. Among hospitalized patients, a significantly decreased aRR was observed for the use of Vit D in the absence of CRTs relative to patients who received CRTs but not Vit D (aRR = 0.30; multiplicity corrected, p = 0.0004). Among patients receiving systemically administered CRTs (e.g., dexamethasone), the use of Vit D was associated with fewer deaths in hospitalized patients (aRR = 0.51) compared with non-hospitalized patients (aRR = 2.5) (P-for-Interaction = 0.0071). Evaluating the effect of modification of these compounds in the context of hospitalization may aid in the management of COVID-19 and provide a better understanding of the pathophysiological mechanisms underlying this and future infectious disease outbreaks.

BACKGROUND: Calcium and vitamin D deficiency is common among Iranian women of childbearing age and poses adverse effects on pregnancy outcomes. The aim of the current study was to determine the prevalence of vitamin D and calcium in a sample of Iranian pregnant women and to assess its correlation with the feto-maternal outcomes. METHODS: In this prospective cross-sectional study, a sample of pregnant women between 15 to 45 years who were in the third trimester were recruited from a number of hospitals in Tehran. Data were collected by the means of a self-developed questionnaire, interviews, physical examination, and paraclinical tests including measuring the serum level of calcium, vitamin D, parathormone (PTH) and phosphorous (Pi). The questionnaire obtained information on age, level of education, socio-economic status, parity, gravidity, calcium intake during pregnancy, as well as feto-maternal outcomes. RESULTS: We included a total number of 233 singleton pregnancies. Most of the subjects (58.4%) had vitamin D deficiency and 12.0% suffered from severe vitamin D deficiency. Vitamin D deficiency was adversely associated with the years of education (p= 0.007), serum level of parathormone (p< 0.001). The Metabolic Equivalent of Task (MET) (p< 0.001), the exercise sequence per week (p< 0.001), sun exposure (p< 0.001), higher rate of sunscreen usage (p= 0.011) and higher BMI (p= 0.005). Vitamin D deficiency was associated with higher rate of cesarean delivery (p= 0.024), higher rate of diastolic hypertension (p= 0.019), higher rate of neonatal jaundice (p= 0.009) and higher rate of neonatal respiratory infections (p< 0.001). Serum level of PTH was a significant risk factor for severe vitamin D deficiency while calcium D supplementation, MET and sunscreen were significant protective factors. CONCLUSION: The prevalence of vitamin D deficiency during pregnancy among Iranian women is extremely high and is associated with adverse pregnancy outcomes including cesarean delivery, neonatal jaundice and neonatal respiratory infections. Low vitamin D supplementation and sun exposure, lack of physical activity and high BMI are the etiologies. Increasing the knowledge along with vitamin D supplementation during the pregnancy is recommended in Iranian population.

Surgical Menopause

Introduction. Patients with surgical menopause have a risk for osteopenic syndrome (OS). Menopausal hormone therapy (MHT) in combination with calcium and vitamin D promotes increase in bone mineral density (BMD). The expression level of vitamin D receptor in mononuclear fraction cells (MNFC) of blood can be considered as a predictive marker of effectiveness of OS therapy. Aim. To search a molecular predictive marker of the effectiveness of OS treatment. Materials and methods. The study included 100 women aged 4055 years with a duration of surgical menopause from 12 months to 6 years. The criterion for including patients in the study was the absence of contraindications to the use of MHT. The subject of the study was the determination of BMD by dual-energy X-ray absorptiometry, polymerase chain reaction diagnostics of the level of expression of vitamin D genes, estradiol and progesterone receptors, determination of 25-OH vitamin D in the blood. Results. Analysis of 12-month OS therapy effectiveness evaluated with a surrogate marker BMD. The increase in BMD up to 34% per year was treated as absence of negative dynamics, more than 4% per year as positive one. Significant effect of combination therapy compared with MHT on BMD in patients with surgical menopause with a low baseline level of BMD (due to hypovitaminosis D) is associated with the anti-inflammatory, bone-protective effect of vitamin D. In both groups of patients not responding; to the prescribed therapy we were able to conduct a comparative analysis of expression level of the target molecules in the MNFC before the start of treatment. The efficacy of MHT and combination therapy for BMD disorders is positively associated with the expression level of vitamin D receptors in MNFC before treatment. Therefore, the vitDR mRNA level is a potential predictive marker of the effectiveness of OS treatment. The expression levels of nuclear estradiol beta receptor and membrane receptor for progesterone in MNFC before treatment showed an upward trend in women responding to therapy. Conclusion. The expression level of the vitamin D receptor in MNFC of blood is significantly lower in the group of women with no/insufficient effect on 12-month combined therapy. This indicator can be considered as a predictive marker of the effectiveness of OS therapy.

Determining Factor

Diagnosis of primary or idiopathic spontaneous pneumothorax is one of exclusion, and in fact defines an entity that may have a difficult or impossible cause to be highlighted by current means, we consider it appropriate to study these etiopathogenic aspects. There is a definite association between alpha-1 antitrypsin deficiency and pulmonary emphysema and indirect spontaneous pneumothorax secondary to an emphysematous pulmonary lesion. Dose of alpha-1 antitrypsin is an immunoturbinimetric method for in vitro determination of alpha-1 antitrypsin in human serum and plasma. This product is calibrated to be used for the Daytona RX analyzer. The serum level of alpha-1-antitrypsin is not a determining factor in the postoperative evolution characterized by the interval until air loss disappears, but certainly exerts some influence, the exact level of which remains to be determined.
