Background: Irisin as an exercise-induced myokine was proposed to improve bone health. This study investigated the role of serum irisin (s-irisin) in patients with osteoporosis (OP) through correlating to most biological bone markers and oxidative stress. Methods: A cross-sectional study recruited an eligible 175 postmenopausal women at Al-Hussien Teaching Hospital, Iraq. They were scanned by DEXA and stratified into two groups based on T-score; the first 95 patients as control group (GI) with −1 ≤ T-score and the second 80 patients as cases group (GII) with T-score ≤ −2.5. Demographic criteria were age, bone mineral density (BMD, g/cm 2 ) and T-score. Serum irisin, total serum calcium (s-calcium), serum inorganic phosphate (s-phosphate), serum alkaline phosphatase (s-ALP), serum 25 [OH] vitamin D, the serum parathyroid hormone (s-PTH), serum Carboxy terminal collagen crosslinks (CTx), serum procollagen type I C-termidnal peptide (s-PICP), serum malondialdehyde (s-MDA) and serum superoxide dismutase (s-SOD) were collected from blood samples. Results: Serum irisin were 31.84 ± 2.65 vs. 20.88 ± 2.71 ng/mL for control and trial groups, respectively. Lower levels of BMD, T-score, 25 [OH] vitamin D, and s-irisin along with a higher serum levels of PTH, CTx, PICP, MDA and SOD were observed in patients with osteoporosis. All parameters were statistically meaningful upon correlation (p< 0.0001), except age and s-calcium (p= 0.0088 and p= 0.187, respectively). Conclusions:The results showed that, a significantly lower serum irisin levels among osteoporosis women, was intimately correlated to most bone turnover markers and it can be considered as encouraging results for clinical application in prediction and treatment of osteoporosis.
Objective To describe the hematological changes, the platelet indices in particular, in pregnant women with coronavirus disease 2019 (COVID-19) compared to healthy pregnant women. Methods A retrospective case-control study conducted at the Al Yarmouk Teaching Hospital, in Baghdad, Iraq, involving 100 pregnant women, 50 with positive viral DNA for COVID-19 (case group), and 50 with negative results (control group); both groups were subjected to a thorough hematological evaluation. Results Among the main hematological variables analyzed, the platelet indices, namely the mean platelet volume (MPV) and the platelet distribution width (PDW), showed statistically significant differences (MPV: 10.87 ± 66.92 fL for the case group versus 9.84 ± 1.2 fL for the control group; PDW: 14.82 ± 3.18 fL for the case group versus 13.3 ± 2.16 fL for the controls). The criterion value of the receiver operating characteristic (ROC) curve for PDW at a cutoff point of > 11.8 fL showed a weak diagnostic marker, while the MPV at a cutoff value of > 10.17 fL showed a good diagnostic marker. Conclusion The MPV and PDW are significantly affected by the this viral infection, even in asymptomatic confirmed cases, and we recommend that both parameters be included in the diagnostic panel of this infection.
Omicron, a severe acute respiratory syndrome coronavirus-2 variant, has spread around the globe, causing dramatic increases in infection rates. Viral mutant antigens were responsible for the strong infectivity, fast replication, and high reinfection rates reported from all ages. Omicron causes clinical symptoms mostly related to the upper respiratory tract with minimal symptoms from the lower respiratory tract besides an urgent presentation of cases that resembled a fatal illness, epiglottitis. Not to mention the long coronavirus disease 2019, which rises exponentially in the Omicrons era. Apparently, the disease has a less aggressive course than earlier variants with lower death rates; however, the infection is not trivial. Severe infection was raised among pediatrics, unvaccinated, and the elderly. Complete vaccine protection is urgently needed to protect the most vulnerable community members. Additionally, self-protective strategies such as wearing a mask and safe social distancing cannot be omitted.
Aim: To verify the role of maternal serum levels of alpha-1-antitrypsin (AAT), an acute-phase inflammatory protein, as a marker for distinguishing between fetal growth restriction (FGR) and normal birth weight in pre-eclamptic women. We correlate serum AAT levels to the essential feto-maternal parameters for an earlier and cost-benefit diagnostic method, thus distinguishing between FGR and normal birth weight in preeclamptic women. Methods: An observational study conducted at the University hospital recruited 100 pregnant women in 32/34 weeks of a singleton single tone pregnancy; all were pre-eclampsia cases. All were tested by laboratory and ultrasound examination. Two sets of data were collected; one is maternal parameters such as blood pressure (BP), maternal serum AAT mean platelet volume (MPV), platelet distribution width (PDW), and serum uric acid levels, and the other is fetal parameters such as amniotic fluid index (AFI), fetal weight centile and estimated fetal weight. Results: A strong negative correlation proved between serum levels of AAT and all study variables except fetal weight (systolic BP, diastolic BP, MPV, PDW, serum uric acid, fetal weight percentile, and AFI) with a correlation coefficient of; À0.95, À0.95, À0.85, À0.93, À0.91, À0.94, and À0.93 respectively. The cut-off value for AAT 0.013 mg/ml showed the highest sensitivity and specificity as a diagnostic marker for FGR. Area under the curve was 0.99. Conclusions: Negative correlations between maternal serum AAT and fetal parameters used to assess FGR were confirmed, suggesting that AAT is closely related to the pathophysiology of FGR among pre-eclamptic patients and may serve as a helpful tool in distinguishing between FGR and normal birth weight babies, pending further validation in feto-maternal outcomes.
Background COVID-19 infection has raised multiple concerns in pregnant mothers; many questioned the risk of vertical transmission and the implication on the feto-maternal outcome. Cardiotocogrm (CTG) is the principal method to observe intrapartum fetal well-being. This paper aims to verify intrapartum CTG changes seen in seropositive COVID-19 mothers versus healthy controls and looks into their relation to subsequent delivery mode and neonatal outcome. Methods A case–control study recruited 90 pregnant women at the labor word of AL Yarmouk Teaching Hospital. All were term pregnancy admitted for delivery. They were grouped into 2: seropositive COVID-19 confirmed by real-time RT-PCR test (30/90) and healthy controls (60/90). We recorded their demographic criteria, laboratory results, CTG changes, delivery mode, and indication. Results COVID-19 cases showed significantly higher pulse rate, temperature, and leukocyte counts. Cesarian deliveries (CS) were higher in cases versus healthy controls (70 % vs. 53.3 %) and P = 0.45. Analysis of the CS indications showed that abnormal fetal heart tracing accounts for 33.3 % versus 15.6 % (P-value = 0.015) for cases versus healthy controls. 60 % of COVID-19 cases exhibited abnormal CTG changes versus 19.4 % in healthy controls. These changes were primarily fetal tachycardia and reduced variabilities. Conclusions The higher incidence of abnormal CTG in COVID-19 cases, alongside infection signs and symptoms, underlies the exaggerated inflammatory reactions inside the pregnant mother. These inflammatory reactions are the main causes of CTG changes and higher CS rates. Therefore, obstetricians are advised to optimize the maternal condition to rectify reactive CTG changes rather than proceeding into urgent CS.
