Neutrophil-lymphocyte ratio as inflammatory marker for clinical prediction and disease severity evaluation of preeclampsia

Background: Pre-eclampsia (PE) is a multisystem disorder that complicates 4-6% of pregnancies and constitutes a major source of morbidity and mortality worldwide. About 10-15% of maternal deaths are directly associated with PE and eclampsia. The aim of this study is to compare the neutrophil-lymphocyte ratio (NLR) values of mild and severe PE with the healthy normotensive pregnant women, in order to study the predictive role of NLR for PE and whether the NLR value has significant difference between normotensive pregnancy, severe and mild PE. Method: A cross-sectional study conducted from January to July 2022 after proper informed consent and ethical clearance. The study population included 194 pregnant women divided into three groups (97 normotensive, 55 mild PE, 42 with severe PE). All the study participants were statistically compared in respect to NLR and the baseline data including age, parity and gestational age. Results: Maternal NLR in mild PE group was statistically increased when compared to normotensive healthy women (p<0.05). Similarly, NLR was significantly higher in severe PE group when compared with normotensive pregnancy group (p=0.00). A statistically significant positive correlation was also seen between SBP (systolic blood pressure) and NLR in PE group (p<0.05). Conclusions: NLR can be used as an inflammatory marker for clinical prediction and disease severity evaluation of PE but further cohort studies are required to determine and establish its role

Pre-eclampsia and platelet indices: a cross sectional study

Background: Pre-eclampsia is a complex disease process originating at the maternal- fetal interface that affects multiple organ systems. The exact pathophysiology of preeclampsia is not known but it is considered to be associated with endothelial cell dysfunction, increased inflammatory responses and hypercoagulability. The receptors located on platelets are activated in pre-eclampsia by several proteases plus the vasoconstriction associated with preeclampsia leads to platelet activation which can be evaluated by platelet indices like platelet count, mean platelet volume (MPV), platelet distribution width (PDW) and palteletcrit (PCT). The objective of this study was to compare the platelet count and platelet indices- MPV, PDW, and PCT in patients with pre-eclampsia and normotensive pregnant women.Methods: A cross sectional study which included a total of 204 patients divided into two groups (102 pre-eclampsia and 102 control. The patients were compared for platelet count and platelet indices like MPV, PDW and PCT.Results: The platelet count (PC) was decreased in pre-eclampsia group as compared to control group with statistically significant difference in means between the two groups (p<0.05). The MPV and PDW also showed significant difference between the two groups (p<0.05) with preeclampsia group having increased MPV and PDW values. The PCT value was lower in pre-eclampsia group as compared to control group but it did not reach statistically significant level.Conclusions: In pre-eclampsia patients while as MPV and PDW showed increased value as compared to control group and the difference between the two had statistical significance, platelet count was lower in them and had statistical significance when compared to control group. Therefore these platelet indices and platelet count can be used to predict and prevent complications arising from preeclampsia

Comparison of serum electrolytes with preeclampsia severity: a cross sectional study

Background: Preeclampsia is a common complication of pregnancy that put women and their fetuses at significant risk and result in life long sequelae. The pathogenesis of this important disease is complex as such the role of different serum electrolytes is being investigated as they are considered important for blood pressure regulation.Methods: A hospital based cross-sectional study of 100 diagnosed cases of preeclampsia divided into mild and severe according to latest International Society for the Study of Hypertension in Pregnancy (ISSHP) guidelines and equal number of age, parity and gestational age matched women (n=100), that acted as control group, with singleton normal pregnancies. Data was analyzed in SPSS V:26. Statistical tests to find out mean standard deviation and One-way ANOVA test were applied to find the significance of associations.Results: In severe preeclampsia group, the mean values of Na+, K+ and Cl- were 134.50±4.24, 4.28±0.74, 106.48±3.41 meq/l respectively in comparison to control group which had 135.57±3.29, 4.12±0.53, 108.20±3.19 meq/l respectively. Results from one way ANOVA showed that there was statistically significant difference between means of the three groups for systolic blood pressure (SBP), diastolic blood pressure (DBP), potassium and chloride levels with p<0.05. A post hoc analysis was used to distinguish the differences in means of these parameters.Conclusions: Estimation of readily available serum electrolytes of sodium potassium and chloride during the course of pregnancy can help to identify and treat preeclampsia and thus reduce the burden of morbidity and mortality in pregnant women

Liver and renal biochemical parameters in preeclampsia: a cross sectional study

Background: Pre-eclampsia is a multisystem disorder of human pregnancy with a genetic predisposition. It occurs more frequently in first pregnancies and leads to elevation in blood pressure and mainly affects maternal renal, cerebral, hepatic and clotting functions. This study evaluated biomarkers of renal and liver function among preeclamptic women. Methods: This was a cross-sectional study conducted among 150 preeclamptic women and 150 normotensive healthy pregnant women in hospital. The baseline data comprising age, gestational age, and blood pressure were obtained. Serum urea, creatinine, and plasma levels of liver enzymes ALT and AST, total protein, albumin, globulin and glucose were measured. Results: The plasma total protein, and albumin in preeclamptic group were significantly decreased (p&lt;0.05) when compared with control. There was statistically significant increase (p&lt;0.05) in urea creatinine, glucose, serum AST, and ALT activities in preeclamptic group. Conclusions: Preeclampsia has harmful effects on renal and liver function as shown by alteration of these parameters

Accuracy of spontaneous breathing trial using ET-CPAP in predicting successful extubation of neonates

Objective: Extubation failure is common in mechanically ventilated neonates. Finding objective criteria for predicting successful extubation may help to reduce the incidence of failure and the length of mechanical ventilation (MV). We conducted this study to determine the accuracy of the spontaneous breathing trial (SBT) and lung function measurements in predicting successful extubation in neonates.Methodology: This cross-sectional validation study was conducted at a tertiary care neonatal intensive care unit (NICU) over 12 months from December 2019 to December 2020. Neonates intubated for \u3e24 hours and considered ready for extubation were enrolled in the study. Neonates who met defined eligibility criteria underwent a three minutes SBT using endotracheal continuous positive airway pressure (ET-CPAP) before extubation. The primary clinical team was blinded to the results, and all neonates were extubated after SBT. Extubation was considered successful if patients remained extubated for 48 hours.Results: Among the 107 infants, 77.5% (n=83) of infants passed the SBT. Of these, 78 were successfully extubated, giving the positive predictive value of 93.97%. The overall extubation success rate was 90% (n=96). The sensitivity and specificity of SBT were 81.2% and 54.5%, respectively. VE (ET-CPAP) and VE-ventilator at a cutoff of ≥238 ml and ≥143.7 ml have an area under the curve (AUC) of 0.77 and 0.75 respectively to predict successful extubation (p-value 0.003, 0.008 respectively).Conclusion: SBT predicts extubation success with pronounced accuracy. Therefore, we propose SBT as a valuable and crucial step that guides clinicians\u27 decision-making regarding extubation preparedness or impending failure in neonates

Establishment of the Invasive Cactus Moth, \u3ci\u3eCactoblastis cactorum\u3c/i\u3e (Berg) (Lepidoptera: Pyralidae) in Pakistan: A Potential Threat to Cultivated, Ornamental and Wild \u3ci\u3eOpuntia\u3c/i\u3e spp. (Cactaceae)

Subsequent to the significant accomplishment of biological control of Opuntia weeds in Australia, the larvae of the cactus moth, Cactoblastis cactorum (native to parts of South America), were released in many countries for the biological control of native Opuntia species (Simmonds and Bennett, 1966). Inauspiciously, larvae were also released in the Caribbean, where the moth spread naturally and by the human support all over the region (García-Turudi et al., 1971). Its enhanced dissemination rate and the biological potential for invasiveness, suggests that the cactus moth is likely to become an invasive pest of Opuntia in the Southeast United States, Mexico, and southwestern America. Its damage is restricted mainly to the plants of genus Opuntia (plants with the characteristic of flat prickly pear pads of the former genus Platyopuntia, now considered to be the part of the genus Opuntia). In this region, plants of this genus provide valuable resources for humans, livestock, and wildlife such as food, medicine, and emergency fodder, while in the arid and semi-arid regions, the plants play key roles in ecosystem processes and soil conservation. At present, the cactus moth has developed into a severe threat to the high diversity of prickly pear cacti, all over the world for both the native and cultivated species of Opuntia (IAEA, 2002)

Hydrogen injection in a dual fuel engine fueled with low-pressure injection of methyl ester of peruvenia thevetia [MEPT] for diesel engine maintenance application

The present work is mapped to scrutinize the consequence of biodiesel and gaseous fuel properties, and their impact on compression-ignition (CI) engine combustion and emission characteristics in single and dual fuel operation. Biodiesel prepared from non-edible oil source derived from Thevetia peruviana belonging to the plant family of Apocynaceaeis. The fuel has been referred as methyl ester of Thevetia peruviana (METP) and adopted as pilot fuel for the effective combustion of compressed gaseous fuel of hydrogen. This investigation is an effort to augment the engine performance of a biodiesel-gaseous fueled diesel engine operated under varied engine parameters. Subsequently, consequences of gas flow rate, injection timing, gas entry type, and manifold gas injection on the modified dual-fuel engine using conventional mechanical fuel injections (CMFIS) for optimum engine performance were investigated. Fuel consumption, CO, UHC, and smoke formations are spotted to be less besides higher NOx emissions compared to CMFIS operation. The fuel burning features such as ignition delay, burning interval, and variation of pressure and heat release rates with crank angle are scrutinized and compared with base fuel. Sustained research in this direction can convey practical engine technology, concerning fuel combinations in the dual fuel mode, paving the way to alternatives which counter the continued fossil fuel utilization that has detrimental impacts on the climate

Effect of palm-sesame biodiesel fuels with alcoholic and nanoparticle additives on tribological characteristics of lubricating oil by four ball tribo-tester

Dilution of engine oil with unburned fuels alters its lubricity and tribological properties. In this research paper, SAE-40 lubricating oil samples were contaminated with known percentages (5%) of fuels (diesel, palm-sesame biodiesel blend (B30), B30 + ethanol, B30 + dimethyl carbonate, B30 + carbon nanotubes and, B30 + titanium oxide). The effect of all these fuels on wear and frictional characteristics of lubricating oil was determined by using a 4-ball tribo tester and wear types on worn surfaces were analyzed by using SEM. Lubricating oil diluted with B10 (commercial diesel) showed highest COF (42.95%) with severe abrasive and adhesive wear than mineral lubricant among other fuels. Lubricating oil diluted with palm-sesame biodiesel (B30 blend) with alcoholic additives showed comparatively less COF, less wear scar diameter and polishing wear due to presence of ester molecules. Lub + B30 + Eth exhibited increment in COF value (35.81%) compared to SAE-40 mineral lubricant. While lubricating oil contaminated with B30 with nanoparticles showed least frictional characteristics with abrasive wear. Lub + B30 + TiO2 showed least increment in COF value (13.78%) among all other contaminated fuels compared to SAE-40 mineral lubricant. It is concluded that nanoparticles in biodiesel blends (B30) helps in reducing degradation of lubricants than alcoholic fuel additives and commercial diesel. (C) 2021 THE AUTHORS.
