Abstract
BACKGROUND Alterations in the components of hemostasis, namely platelet function, the procoagulant, anticoagulant, and the fibrinolytic systems, are observed in sickle cell anemia (SCA) and are in favor of a procoagulant phenotype. Therefore, study of protein C and antithrombin (AT) levels in patients with SCA in steady state may be used in the treatment and/or prevention of SCA-related thrombotic complications. We studied the changes of these naturally occurring anticoagulants in patients with SCA attending the sickle cell clinic in Ahmadu Bello University Teaching Hospital, Zaria. METHODS We conducted a case-control study involving 50 SCA (HbSS) patients in the steady state as cases and 25 healthy volunteers with normal hemoglobin (HbAA) as controls. Protein C and AT levels were estimated by semi-automation using Diagnostica Stago hematology coagulation analyzer. Frequencies, proportions, and independent t test were performed using SPSS version 20. RESULTS The mean ages of both the patients and controls were 23.80 ± 7.46 and 24.28 ± 3.48 years, respectively, and study participants comprised 40 (53.0%) women between the ages of 15-50 years and 15-34 years (P = 0.76). The mean values of protein C and AT levels in patients with SCA in the steady state and the control group were 60.26 ± 20.58% versus 81.30 ± 19.74%, 95% CI 11.13-30.96, and 42.11 ± 5.01% versus 61.88 ± 11.27%, 95% CI 16.03-23.51 with P values (P < 0.001), respectively. CONCLUSIONS This study showed that there was a significant decrease in the levels of protein C and AT between the SCA patients in the steady state and the controls. We recommend baseline investigations of these naturally occurring anticoagulants in patients with SCA, especially in those with frequent vaso-occlusive crises. This will give us an insight into the additional pathophysiologic mechanism in SCA-related thrombotic complications for better patient management and outcome.

Abstract
AIM This single-centre randomized, double-blind, placebo-controlled clinical trial assessed the effect of a preoperative, single, oral dose of prednisolone on postoperative pain and postoperative analgesic intake in patients with symptomatic, irreversible pulpitis in mandibular molars. METHODOLOGY Four hundred participants, randomly assigned to two equal groups, received either 40 mg prednisolone or placebo tablets 30 min before single-visit root canal treatment. Patients recorded their pain level 6, 12 and 24 h after treatment on a 100-mm visual analogue scale. All patients received a sham capsule to take if needed as a postoperative analgesic, and, if the pain persisted, an analgesic was prescribed. The relative risk reduction and 95% confidence intervals (CI) were estimated for binary data. Mann-Whitney U-test was used to compare postoperative pain intensity between groups. RESULTS The relative risk reduction in pain incidence was 20.31% (95% CI: 12.03%, 27.82%) at 6 h, 23.39% (95% CI: 14.75%, 31.16%) at 12 h and 28.85% (95% CI: 18.08%, 38.20%) at 24 h. Prednisolone had significantly less post-obturation pain intensity compared to placebo at 6, 12 and 24 h (P < 0.001). The relative risk reduction in sham-capsule intake was 54% (95% CI: 38%, 66%) and of analgesic intake was 55% (95% CI: 3%, 79%). No adverse effects were recorded. CONCLUSION Preoperative oral administration of a single dose of 40 mg prednisolone was beneficial to control short-term post-obturation pain after single-visit root canal treatment in patients with symptomatic irreversible pulpitis reducing pain incidence after 24 h by approximately 30% and postoperative analgesic intake by approximately 55%.

Abstract
Sickle cell disease affects about 150,000 births annually in Nigeria. Early diagnosis is hampered by factors such as centralized and urban localization of laboratories, high cost of diagnostic equipment and inadequate skilled manpower to operate them. The need for a low-cost, portable, easy-to-use diagnostic test for sickle cell disease is critical, especially in resource-poor countries. In this study, we evaluated the performance characteristics of a novel point-of-care testing device (SickleSCAN™), and its acceptability and feasibility, as a possible screening tool for sickle cell disease. In the first phase, we assessed the performance characteristics of SickleSCAN™ by evaluating 57 subjects comprising both children and adults attending a primary health center, for Hb SS (βS/βS; HBB: c.20A>T), Hb SC (βS/βC; HBB: c.19G>A) and Hb AS (βA/βS) using SickleSCAN™, cellulose acetate electrophoresis (CAE) and high performance liquid chromatography (HPLC). Performance characteristics such as diagnostic sensitivity and specificity were compared to HPLC as a standard method. We subsequently undertook a second phase wherein the acceptability and feasibility of the device for sickle cell disease screening, was evaluated using semi-structured and structured questionnaires among 197 healthcare personnel and 221 subjects, respectively. Sickle cell disease was carried by 3.4% of the subjects. The diagnostic sensitivity, specificity and test efficiency of SickleSCAN™ for sickle cell disease (Hb SS and Hb SC), were 100.0, 98.2 and 98.2%, respectively. Findings from this study showed SickleSCAN™ to be a viable screening tool that can easily be applied in community-based screening for early diagnosis of sickle cell disease with little expertise and low cost.

Abstract
CONTEXT Sickle Cell Anaemia (SCA) is a genetic disorder with a life-long disability, which is of public health importance. The diversity in its clinico-pathologic and laboratory presentations may be due to the interplay between additional genetic differences and environmental factors. The genetic factors may be within the β-globin gene itself, the β-globin gene cluster or elsewhere in the genome. AIM To characterize the β-globin gene for variations associated with the Sickle Cell mutation. SETTINGS AND DESIGN A cross-sectional descriptive study involving 51 adult SCA patients attending Sickle Cell Clinic of Haematology Department Ahmadu Bello University (ABUTH) Zaria, Kaduna State, Nigeria. METHODS AND MATERIAL The buccal swab specimens were collected and β-globin gene DNA sequencing was done. The sequences obtained were compared with a Genbank Reference β-globin gene (NC_000011.9) using Basic Local Alignment Search Tool (BLAST), and variations noted. Data generated were analyzed using SPSS Version 20.0. STATISTICAL ANALYSIS USED Data generated was summarized by using charts, means±2SD, and 95% confidence intervals. RESULTS There were 40 (78.43%) females and 11 (21.57%) males. The mean age of the participants was 25.35 ± 7.67 years, 95% CI (23.20, 27.51). The classic sickle cell mutation A T was present in all participants. The mean number of β-Globin gene variations was 8.61±11.30, 95% CI (5.43, 11.78). The number of Substitutions were 122 (27.79%), insertions 184 (41.91%), and deletions 133 (30.30%). These occurred in various combinations. The mean number of substitutions, insertions, and deletions were 2.39±3.23, 3.61±7.66, and 2.60±2.46 with 95% CIs of (1.48, 3.30), (1.45, 5.76), and (1.92, 3.30) respectively. CONCLUSIONS There are β-globin gene variations in SCA patients in Zaria, and locally relevant genetic database of the SCA population will be the cornerstone in understanding genotype-phenotype interactions in this disorder.

Abstract
This study aimed to determine whether follicular output rate (FORT) can predict the clinical pregnancy rate in women with unexplained infertility undergoing IVF/ICSI. This was a prospective study conducted at Dar El Teb subfertility centre in Cairo between June 2014 and July 2016. A total of 303 women with unexplained infertility, who were undergoing IVF/ICSI, were divided into three groups according to FORT tertile values. FORT was calculated as pre-ovulatory follicle count/antral follicle count × 100. There was a progressive and significant increase from the low to the high FORT groups in the clinical pregnancy rate (29.9%, 43.3% and 57.8%; P < 0.001), number of retrieved oocytes (5.4 ± 1.5, versus 6.8 ± 2.8, and 7.4 ± 2.1; P < 0.001), and fertilization rate (48.4 ± 21.8 versus 55.3 ± 20.3 and 57.4 ± 19.2; P = 0.006). Multivariate logistic regression analysis revealed that the correlation between FORT and pregnancy was independent of potential confounding factors (P = 0.008). We concluded that FORT is an independent variable affecting the clinical pregnancy rate in IVF/ICSI cycles. Higher FORT values had better oocyte yield and clinical pregnancy rates in women with unexplained infertility undergoing IVF/ICSI with potentially normal ovarian response.

Abstract
The present research task is aimed to evaluate the role of exogenous α-lipoic acid (ALA) (100 mg/kg body weight) as hepatoprotective and potent antioxidant in amelioration of copper nanoparticle (CNP)-induced hepatotoxicity. Forty male rats were randomly assigned into four equal groups: group I (control), group II received CNPs, group III received CNPs + ALA, and finally group IV received ALA for 2 months. At the end of the experimental period, the rats were decapitated, and blood and liver tissue samples were collected for measurement of liver function tests, antioxidant status, lipid peroxidation (LPO), copper content, expression of some apoptotic genes, and histopathological analysis. CNPs induced marked hepatic damages as evident by severe alteration in hepatic biomarkers. This was accompanied by a significant elevation in hepatic LPO and induced nitric oxide, copper content, and expression level of apoptotic genes (C-myc and C-jun). In contrast, marked depletion for antioxidant parameters was detected. These findings were confirmed with severe pathological alterations. Coadministration of ALA as a powerful antioxidant attenuates the hepatotoxic effects of CNPs through improvement of liver parameters, oxidative status, genetic changes, and preservation of liver integrity through histopathological analysis. These results suggest that consumed ALA could be used as an applicable hepatoprotective agent against oxidative damage mediated by nanoparticles intoxication.
