Psychosocial concerns of Nigerian women with breast and cervical cancer

Cancer has the potential to provoke worries which should be assessed in order to adequately respond to patients' problems. We highlight in this paper the problems that concerned 30 women with cervical cancer (mean age 51.2) and 76 with breast cancer (mean age 44.9), how these concerns affected their emotional lives, and the factors associated with these worries. They were interviewed with the 33-item modified version of a German questionnaire rating psychosocial concerns (FBS) by Sullwold, and Goldberg'rsquo;s General Health Questionnaire (GHQ-12) for psychopathological symptoms. Cervical cancer patients had significantly higher FBS and GHQ-12 scores than breast cancer. Breast cancer cases had FBS scores similar to those of women with sickle cell disease and insulin-dependent diabetes mellitus. The commonest recurrent worries in both groups were depression about their condition (45%), thoughts of death (37%), insomnia (33.3%), bodily odour (30%), impairment of work efficiency (30%) terrifying dreams (27%) and fear of illness being life-long (25%). Over 90% denied experience of worries indicating social stigma. FBS scores were significantly correlated with GHQ scores and both were negatively associated with adequacy of social contacts. These data suggest the need for psychosocial intervention in such cases in Nigeria. © 1998 John Wiley & Sons, Ltd.     

Strength and Acid Resistance of Ceramic-Based Self-Compacting Alkali-Activated Concrete: Optimizing and Predicting Assessment

The development of self-compacting alkali-activated concrete (SCAAC) has become a hot topic in the scientific community; however, most of the existing literature focuses on the utilization of fly ash (FA), ground blast furnace slag (GBFS), silica fume (SF), and rice husk ash (RHA) as the binder. In this study, both the experimental and theoretical assessments using response surface methodology (RSM) were taken into account to optimize and predict the optimal content of ceramic waste powder (CWP) in GBFS-based self-compacting alkali-activated concrete, thus promoting the utilization of ceramic waste in construction engineering. Based on the suggested design array from the RSM model, experimental tests were first carried out to determine the optimum CWP content to achieve reasonable compressive, tensile, and flexural strengths in the SCAAC when exposed to ambient conditions, as well as to minimize its strength loss, weight loss, and UPVL upon exposure to acid attack. Based on the results, the optimum content of CWP that satisfied both the strength and durability aspects was 31%. In particular, a reasonable reduction in the compressive strength of 16% was recorded compared to that of the control specimen (without ceramic). Meanwhile, the compressive strength loss of SCAAC when exposed to acid attack minimized to 59.17%, which was lower than that of the control specimen (74.2%). Furthermore, the developed RSM models were found to be reliable and accurate, with minimum errors (RMSE < 1.337). In addition, a strong correlation (R > 0.99, R² < 0.99, adj. R² < 0.98) was observed between the predicted and actual data. Moreover, the significance of the models was also proven via ANOVA, in which p-values of less than 0.001 and high F-values were recorded for all equations.     

Assessment of Renal Function Status in Steady-State Sickle Cell Anaemic Children Using Urine Human Neutrophil Gelatinase-Associated Lipocalin and Albumin: Creatinine Ratio

IntroductionSickle cell anaemia is characterized by defective haemoglobin synthesis and is associated with both endocrine and metabolic alterations. The effects of this clinical condition on kidney function are multifactorial and often begin early in childhood. This study aims to assess renal function in children with sickle cell anaemia using urine albumin:creatinine ratio (ACR) and urine human neutrophil gelatinase-associated lipocalin (NGAL).MethodsThis case-control study was conducted on 200 children aged 5–15 years in 2 tertiary hospitals in South West Nigeria: 150 were of haemoglobin S genotype and 50 were of haemoglobin A genotype. Serum urea, creatinine, urine albumin, and NGAL were assayed by known standard methods. eGFR, urine ACR, and urine NGAL/creatinine ratio (urine NCR) were calculated.ResultsThe weight, height, BMI, systolic blood pressure, plasma urea, plasma creatinine, and spot urine creatinine of the HbS genotype children were significantly lower compared to that of the HbA genotype children. The eGFR, spot urine albumin, and urine ACR were significantly higher in the HbS group compared to the HbA group. There was no significant difference in the spot urine NGAL and urine NCR between the 2 groups, though both were higher in the HbS group compared to the HbA group.ConclusionsKidney injury probably starts early in childhood in sickle cell individuals as indicated by the higher urine ACR detected in them. We infer that urine NGAL and uNCR are not sensitive markers of kidney disease especially in young sickle cell individuals possibly because of the hyperfiltration present at this age.     

COVID-19 in Nigeria: Why continuous spike in cases?

正1. COVID-19 in Africa The global emergence of the novel coronavirus disease (COVID-19)in December, 2019 became a major turning point in the global health system. As at 4th May, 2020, the Republic of South Africa, Egypt and Nigeria had 6 783, 6 465 and 2 558 confirmed cases of COVID-19,respectively[1].Surprisingly,the number of cases in South Africa has risen to 563 598 cases with 10 621 deaths, and the number of
