Sickle cell anemia (SCA) is an inherited disorder of hemoglobin. Each year over 150,000 children in Africa are born with SCA. Cognitive impairment is a common complication of SCA. This case-control study evaluated cognitive function in 41 adolescents and adults with SCA and an equal number of healthy demographically matched controls using the community screening interview for dementia (CSID), Trail Making Test A (TMTA), Saint Louis University Mental Status examination (SLUMS), and Mini Mental State Examination (MMSE). Mood (anxiety and depression) was assessed using the Hospital Anxiety and Depression Scale (HADS). The controls had better total scores on all screening instruments; however, the difference between their performance and that of the SCA adults was not statistically significant; SLUM (p 5 0.179), TMTA (p 5 0.359), MMSE (p 5 0.241), and CSID (0.494). On specific task, the controls performed significantly better based on SLUM (naming), p 5 0.016; SLUM (repetition), p 5 0.015; SLUM (recall), p 5 0.003; and CSID (language expression), p 5 0.001. The systolic blood pressure (SPB) was inversely correlated with the MMSE scores (p 5 0.009). In addition, there was direct linear correlation between the creatinine levels and the MMSE scores (p 5 0.009). The proportion of SCA patients compared with the controls that had abnormal mood were anxiety (7.3% vs. 4.9%), borderline anxiety (17.1% vs. 4.9%), depression (2.4% vs. 2.4%), and borderline depression (14.6% vs. 2.4%). SCA was associated with an increased prevalence of cognitive impairment in adults when compared to controls. SCA is associated with a higher proportion of mood abnormalities.

Human immunodeficiency virus (HIV)-infected individuals have been shown to have a high prevalence of sleep disturbances. Both the effects of the virus and the antiretroviral drugs may cause sleep disturbances. We sought to determine the prevalence and predictors of sleep disorders among HIV seropositive adult subjects presenting at an outpatient hospital setting. One hundred and fifty six subjects were recruited for the study by using a sleep disorder screening questionnaire. The mean ages of the participants were 38.7 6 9.23 and 39.5 6 9.23 for those with and those without sleep disorder, respectively. The prevalence rate of sleep disorders was 46.2%. Elevated systolic blood pressure, lower CD4 count levels, and being on the highly active antiretroviral therapy combination TDF/3TC/ATZ/lpvr were associated with sleep disorders. The high prevalence rate observed necessitates routine screening for sleep disorders among HIV/AIDs patients.

Infection with hepatitis B or C viruses is still one of the most dreaded infectious diseases worldwide. Health education and screening, particularly among vulnerable groups, are the most cost-effective interventions that can be provided in developing countries. Facility and community-based provision, of effective strategic health education and counseling, are dependent on better understanding of the factors that may be associated with the level of knowledge on hepatitis. One of such groups is men who sleep with men (MSM) or homosexuals, who are at high risk of hepatitis infection through unprotected anal intercourse. This study was therefore aimed at assessing the knowledge of hepatitis infection among MSM in Calabar, a metropolitan city in the oil-rich Niger-Delta region of Nigeria. Cross-sectional study design was utilized. The snow-ball sampling method was used to recruit subjects, with self-administration of structured questionnaires. Questionnaire assessed awareness, causes, sources, consequence, and prevention of hepatitis infection. Knowledge scores were obtained for each subject. Chi-square was used to assess factors associated with knowledge, with p-value fixed at 0.05. Sixty-nine (69) consenting subjects were surveyed, with mean age of 22.5 6 3.2 years, ranging from 16 to 31 years. Mean knowledge percentage score was 43.5 6 32.0, ranging from 0% to 100%. Age group, occupation, and other sociodemographic characteristics were not significantly associated with the knowledge of hepatitis infection. There is inadequate knowledge of hepatitis infection among MSM in the study area. This inadequacy appears worse among receivers, who are even at higher risk of sexually transmitted infections compared with inserters. These findings have implications for control of viral hepatitis in sub-Saharan Africa.

This research was conducted for estimating the knowledge and prevention of nosocomial infection among ward nurses at Federal Medical Centre (FMC), Umuahia Abia state. Four objectives were set, and four questions were formulated. A descriptive survey research method was used for the study. A sample size of one hundred and fifty (150) nurses was drawn from eight wards (medical and surgical), at FMC, Umuahia. A self-developed questionnaire with seventeen (17) structured questions was the instrument of data collection. Data were collected, analyzed, and presented in tables, pie chart, bar chart, histogram, and percentages. The results revealed that the nurses were well knowledgeable about nosocomial infection, although little deficiencies existed in the area of infection control practice and compliance, such as hand washing frequency. This study therefore recommends continuing education/seminar/workshop for all health care givers, to sensitize them with the knowledge and practice of nosocomial infection.

This paper reviews the pathophysiology of cervical spondylotic myelopathy (CSM) and several surgical approaches for the treatment of CSM. CSM is a degenerative disease with severe morbidity. The pathophysiology of CSM involves static, dynamic, and ischemic factors. The management of mild CSM typically involves conservative treatments and medication; whereas, moderate and severe CSM are better treated surgically. Surgical treatments for CSM are basically classified into anterior and posterior surgeries. The common techniques are anterior cervical discectomy and fusion (ACDF), anterior cervical corpectomy and fusion (ACCF), laminectomy, and laminoplasty. Each technique has its own advantages and disadvantages. In this paper, we review the research papers from PubMed database to elaborate the advantages and disadvantages of each technique.

Osteoarthritis (OA) is the most common form of arthritis that affects cartilage joints and leads to disability. OA becomes the major public health problem, as it is the most leading cause of disability and morbidity worldwide. Treatment choices for OA can be classified into several categories such as non-pharmacologic, pharmacologic, surgical therapy, and cell-based therapy. There is no curative treatment for OA, while conventional treatments that are commonly used focus on alleviating the pain as the main symptom of the disease. Mesenchymal stem cells (MSCs) that can be found in several tissues of human body offer a new strategy for OA treatment owing to their ability to differentiate into chondrocytes. This article provides an overview about the basic concept of osteoarthritis as well as an insight about the MSCs therapy, including their basic characteristics, source, and transplantation strategies in the OA area.

Cardiovascular diseases (CVDs) have continued to be a leading cause of death among adults. Civil servants constitute vital workforce, and high CVD burden in this group has implications for national productivity. Unfortunately, guided cardiovascular health education interventions are uncommon. This study assessed the effect of an educational intervention on knowledge and practice of CVD prevention among Nigerian civil servants. Quasi-experimental study design was employed among subjects in distant communities in Cross River State. Multistage technique was used to recruit 172 subjects into one control group (Ogoja) and two intervention groups (Calabar and Ikom). The first intervention group received 4-h daily, 5-day cardiovascular health education, with emphasis on burden, risk factors, and preventive measures including nutrition, stress, alcohol, medicals, exercise, and smoking. The second intervention group received the same content of education, but with the use of Food, Rest for stress management, Alcohol, Medicals, Exercise, and Smoking (FRAMES) as guide for delivery. Questionnaires were used to assess knowledge and practice at baseline and post-intervention. Data were analyzed using SPSS version 20.0. Knowledge scores and practice of CVD prevention were compared between study groups using inferential statistics. Mean age was 46.3 7.4 years, and no significant difference in sociodemographic characteristics was observed by comparing the study groups (p 0.05). Baseline knowledge and practice of preventive measures were generally poor, and no significant difference was observed by comparing the groups (p 0.05). At 12 weeks post-intervention, knowledge of CVD was higher in the intervention groups compared with the control group (p 0.05). Unlike control group, both intervention groups had improvement in physical exercise, medical screening, and fruit consumption (p 0.05). There was no significant difference in postintervention knowledge and practice of CVD prevention by comparing both intervention groups (p 0.05). For effective delivery of cardiovascular health education, the use of “FRAMES” is as effective as its nonuse. Further studies in other settings are recommended.

Diarrhea pathophysiology and constipation are multifactorial gastrointestinal (GI) disorders characterized by intestinal peristalsis disruption of and an irregularity in secretion/absorption process. Oxidative stress, as an imbalance in prooxidants/antioxidants, has recently been recognized as a significant player in these GI disturbances. In this respect, numerous studies were performed and have shown that the deleterious effects on GI tract were accompanied by accumulation of oxidants and depletion of antioxidant system. Antioxidant remedy is necessary in scavenging free radicals and reactive oxygen species preventing oxidative stress-induced GI interruptions.

The emergence of a chronic medical illness such as Human Immune Deficiency Virus and Acquired Immunodeficiency Syndrome (HIV/AIDS) may be the time when people turn to the Sacred through spirituality and religion. HIV is a chronic illness that requires strict adherence to medication regimens that may be influenced by spirituality/religion. This study was aimed at finding the association between spirituality/religion and adherence to highly active antiretroviral therapy (HAART) in adult HIV/AIDS patients. This is a cross-sectional descriptive study of 370 patients. Adherence was measured using an adapted adult AIDS clinical trial group (AACTG) and visual analogue scale (VAS) tools. Spirituality was assessed using Functional Assessment of Chronic Illness Therapy-Spirituality Expanded (FACIT-Sp-Ex) scale, religiosity with Duke University Religion index (DUREL), and religious coping with Brief Religious Coping (RCOPE) scale. Adherence rates were 86.2 and 43.8% using AACTG and VAS tools, respectively. Statistical significant correlation was found between spirituality and adherence to HAART (r 5 0.265; p 5 0.00). Also, significant correlation was found between positive religious coping and adherence (r 5 0.15, p 5 0.003). Odds ratio indicated that female respondents were 1.6 times more likely to be adherent, compared with males. Similarly, every unit rise in spirituality score yielded a 1.3 times increased likelihood of adherence to HAART on multiple logistic regression of adherence to HAART with relevant predictors. Both spirituality and positive religious coping have positive influence on optimal adherence. Therefore, the training of health care personnel to assess and provide spiritual care and involvement of chaplains/religious leaders is advocated for improved adherence.

The amount of glycosylated hemoglobin (HbA1c) reflects the long-term glycemic control of patients with diabetes. HbA1c also predicts the risk for the development of diabetic complications such as cardiovascular disease (CVD). Patients with type-2 diabetes and the characteristic of dyslipidemia are frequently found. Also, dyslipidemia plays as an independent risk factor for CVD. This study was aimed to evaluate the relationship between glycemic control status with serum individual lipid profiles and lipid ratios in patients with type-2 diabetes. This cross-sectional study consisted of 80 patients. Depending on the HbA1c level, the patients were divided into two groups, good glycemic control group (HbA1c 7.0%, n 5 15) and poor glycemic control group (HbA1c 7.0%, n 5 65). The association of HbA1c with individual lipids (TC, TG, HDL-C, LDL-C, Non- HDL-C) and lipid ratios (TC/HDL-C, TG/HDL-C, LDL-C/HDL-C, monocyte/HDL-C) were analyzed. The value of individual lipids and lipid ratios did not correlate with HbA1c level (p-value 0.05). Parameters of individual lipids and lipid ratios were not independently associated with poor glycemic control, which was analyzed by logistic regression. ROC analysis found both LDL-C and LDL-C/HDL-C were not accurate to be used as a prognostic indicator of poor glycemic control in patients with type-2 diabetes (p 5 0.155, p 5 0.297, respectively). The present study found that there was no association between individual lipids and lipid ratios with glycemic control status.

Threadlike filarial nematodes have been identified as the causative agent of filariasis. Cutaneous filariasis is caused primarily by Loa loa, Onchocerca volvulus, and Mansonella streptocerca. These parasites occupy the subcutaneous layer of the skin. However, other filarial parasites are usually associated with varying degrees of dermatological manifestations. In the present discourse, two cases of cutaneous filariasis were diagnosed in two female patients (21 and 40 years old, respectively) in Remitch Clinic and Maternity located in a nonriverine community in Ekpoma, Edo State, Nigeria. In this report, patients with body mass index (BMI) of 18.97 and 23.45 kg/m2, respectively, presented on two different occasions at least 6 months apart with hyperpigmented skin lesions in the upper and lower limbs, respectively. There was associated intense pruritus with no evidence of lymphadenopathy and lymphoedema. Following laboratory confirmation of filariasis, the patients were placed on a single oral dose combination of albendazole (400 mg) 1 ivermectin (200 mcg/kg), while oral doses of loratadine 10 mg were administered daily for 5 days. Patients were carefully followed up for 6 weeks during which recession of the lesion and untoward reactions were monitored. It was observed that within 6 weeks of treatment, there was a dramatic recession of skin lesion. Adverse effect reported from use of the combination was mild. This case report revealed that cutaneous filariasis is not an uncommon presentation of filariasis infestation in Nigeria. The report also validates the safety and efficacy of the combination in the management of cutaneous manifestation of the disease.

Soil salinity is one of the most severe factors limiting growth and physiological response in cowpea plants. In the present study, the effect of rhizobacterium strains BR2 and BR3 on the growth of cowpea (Vigna unguiculata L.) varieties—Pusa Sukomal and RC101—tolerance to 0, 25, 50, and 75 mM concentrations of NaCl salinity was evaluated. The rate of growth, in general, was high in plants irrigated with 25 mM NaCl saline water as compared to control, and thereafter, the growth reduced with increase in salinity concentrations. The results revealed that treating the seeds with rhizobacteria accompanied by NaCl salinity increased growth parameters of the cowpea plant as compared to the seeds irrigated with sodium chloride alone. Treatment with rhizobacteria mitigated the harmful effect of NaCl, and the growth was significantly better than the plants growing in saline water without rhizobacterium inoculation. The overall performance of Pusa Sukomal with BR3 strain was found to be better than the other combinations tested. Flowering in field plants started within 45 days of sowing, and the seeds in plants irrigated with saline water, in the presence of rhizobacterium, were found to be healthy as compared to control seeds. Seed protein profile was analyzed by SDS PAGE gel studies.

Changes in consumption behavior to instant food cause various health problems, such as obesity, dislipidemia, and atherosclerosis. A study was conducted to investigate Moringa oleifera extract as an anti-inflammation product that decreases the levels of biochemical markers IL-1 and TNF-a. This experiment was done with randomized pre- and posttest control-group design, employing 40 Wistar rats separated into five groups: control group 0% M. oleifera leaf extract (P0), treatment group 1 with 10% M. oleifera leaf extract (P1), treatment group 2 with 15% M. oleifera leaf extract (P2), treatment group 3 with 20% M. oleifera leaf extract (P3), and treatment group 4 with 25% M. oleifera leaf extract (P4). This research observed that intake of 20% M. oleifera leaf extract results in the highest significant decrease of 15.42% of IL-1 level (134.64 6 1.98 to 113.87 6 4.30 pg/mL) and decrease of 45.63% of TNF-α level (28.62 6 1.25 to 15.56 6 7.20 pg/mL). Therefore, it can be concluded that intake of M. oleifera leaf extract by Wistar rat has anti-inflammatory effects on chronic dyslipidemia through decrease of IL-1 and TNF-α levels and histopathology profile. Further research is required to determine whether the application of M. oleifera leaf extract (daun kelor) in humans will have similar anti-inflammation effects.

Cognitive dysfunction including dementia is a common complication of chronic kidney disease (CKD) that has just been recently appreciated. It has negative outcomes in the management of patients with CKD. This study explored the possible biochemical and clinical features of patients with CKD that can predict the occurrence of cognitive impairment in patients with moderate to severe CKD. We evaluate patients with stages 3-5 CKD for the occurrence and predictors of cognitive impairment. Multiple areas of cognitive function were tested in this single-center study using Community Screening Interview for Dementia (CSID) and Trial-Making Test A (TMTA)/Trial-Making Test B (TMTB). Cognitive impairment was correlated with patients’ routine biochemical, hematological, and selected clinical parameters. We observed a negative correlation between cognitive impairment and patient’s serum calcium (r 5 0.240; p 5 0.033) and estimated Glomerular filtration rate (eGFR) (r 5 0.379; p 5 0.0006). Therefore, eGFR is an accurate predictor of cognitive dysfunction in patients with moderate to severe CKD. Early evaluation of cognitive function in CKD is indeed advised for optimal outcome in the management of patients with CKD.

The prevalence of parasitic infections such as malaria, which leads to decrease in hematological indices, the major cause of anemia, constitutes a serious health challenge in many developing countries such as Nigeria. This study investigated the effect of methanol seed extract of Aframomum melegueta on selected hematological indices of 2,4-dinitrophenylhydrazine (2,4-DNPH)-induced anemic rats model. The toxicity study and qualitative phytochemical screening of the extract were carried out using standard procedure. Twenty Wistar rats were grouped into five of four rats each (n 5 4). Group I: Normal control; Group II: Negative control; Group III: administered 20 ml/kg b.w. of Astifer (Standard drug); Group IV and V were administered 200 and 400 mg/kg b.w. of the extract, respectively. The animals of Groups II to V were induced with 2,4-dinitrophenylhydrazine (20 mg/kg b.w.) once daily for seven consecutive days; their blood samples were collected by ocular puncture into heparinized capillary tubes for hematological analysis and animals with packed cell volume (PCV) 30% reduction were considered anemic for the study. The result of the qualitative phytochemical analysis showed that the methanol extract tested positive to alkaloids, carbohydrate, saponins, flavonoids, steroids, terpenoids, and anthraquinones. Acute toxicity and lethality studies on methanol extract showed an oral LD50 equal or less than 5000 mg/kg b.w. in mice. The rats administered 20 ml/kg b.w. of Astifer showed significant (P 0.05) increase in PCV, hemoglobin, red blood cell (RBC) count, white blood cell (WBC) count, and neutrophils count compared with the normal control animals. The rats administered 200 mg/kg b.w. of A. melegueta showed significantly (P 0.05) higher PCV and WBC count; non significant (P 0.05) decrease in hemoglobin count, RBC, platelet, neutrophils and lymphocyte count compared with the normal control animals. The rats administered 400 mg/kg b.w. of A. melegueta showed significant (P 0.05) increase in hemoglobin, platelet, erythrocyte sedimentation rate (ESR) and neutrophils count; non significant (P 0.05) lower PCV, RBC, WBC count, and lymphocyte count compared with anemic rats administered with 0.3 ml of normal saline. It can be concluded that Aframomum melegueta seed has beneficial immunological and hematological properties in Wistar rats and possessed erythropoietic potentials at minimal dose that support its use for treating anemia.
