    Background: The evaluation of degree of ventricular enlargement should be based on established indices rather than on personal experience as this is highly subjective. Our aim was to establish normal values for Evans index in a Nigerian adult population as none has been found in the Nigerian medical literature. Materials and Methods: Axial computerized tomographic brain scans of 488 normal subjects were reviewed retrospectively. Of them, 319 (65.36%) of the patients were males and 169 (34.63%) were females; their ages ranged from 18 to 84 years with a mean age of 37.26 years. The images were acquired using a multi-slice GE Sigma excite scanner. Evans index was measured as the linear ratio of the total width of the frontal horns of the cerebral lateral ventricles to the maximum intracranial diameter. Results: The mean value for Evans index for the studied population was 0.252 ± 0.04. The EI increased with age and it was slightly higher among males. The difference in Evans value in males and females was not statistically significant. Individuals above 60 years old had the highest Evans values in both sexes. Conclusion: This study has established ranges of normal value for Evans index in a Nigerian population. It agrees with the diagnostic cut-off value of > 0.3 for hydrocephalus and it compares well with that of the Caucasians. PMID:25552852

    Background: A carefully performed facial analysis can serve as a strong foundation for successful facial reconstructive and plastic surgeries, rhinoplasty or orthodontics. Aim: The purpose of this study is to determine the facial features and qualities of the Igbo Nigerian adult male using photometry. Materials and Methods: One hundred and twenty subjects aged between 18 and 28 years were studied at the Anambra State University, Uli, Nigeria. The frontal and right lateral view photographs of their faces were taken and traced out on tracing papers. On these, two vertical distances, nasion to subnasal and subnasale to menton, and four angles, nasofrontal (NF), nasofacial, nasomental (NM) and mentocervical, were measured. Results: The result showed that the Igbo Nigerian adult male had a middle face that was shorter than the lower one (41.76% vs.58.24%), a moderate glabella (NF=133.97°), a projected nose (NM=38.68°) and a less prominent chin (NM=125.87°). Conclusion: This study is very important in medical practice as it can be used to compare the pre- and post-operative results of plastic surgery and other related surgeries of the face.

    Zinc (an essential trace element) and cadmium (a ubiquitous environmental pollutant with acclaimed toxicity) have been found to occur together in nature, with reported antagonism between the two elements. The present study aimed at determination of plasma levels of zinc (Zn) and cadmium (Cd) and their interrelationship in adult Nigerians. The series comprised adults (n=443) aged ≥18 yrs (mean ± SD 38.4±13.7 yrs), consisting of 117 males, 184 non-pregnant and 140 pregnant females. Sociodemographic data were collected by questionnaire while anthropometrics were determined using standard methods. Plasma Cd and Zn were determined by using an atomic absorption spectrophotometer. The mean plasma zinc and cadmium were 94.7±18.1 μg/dl and 0.150±0.548 μg/dl, respectively. Age, sex, pregnancy, and parity had no effect on either plasma Zn or Cd. Although educational level had no effect on plasma Zn, it had a significant effect on Cd; subjects possessing either secondary or tertiary education had significantly lower plasma Cd than subjects without formal education. Moreover, there seemed to be an inverse relationship between Cd and Zn, but this was not statistically significant (r=–0.089; p=0.061). Although plasma Zn was not related to BMI (r=0.037; p=0.432), Cd was significantly negatively correlated with BMI (r=–0.124; p=0.009). It may be concluded that adult Nigerians in Ebonyi State have elevated plasma levels of Cd, with apparent impact on the levels of plasma Zn. This has important public health implications considering the essential roles of Zn in the protection of Cd mediated adverse health effects. While food diversification is recommended to improve plasma Zn, efforts should be made to reduce exposure to Cd to mitigate partially its possible adverse effects. PMID:27486364

    Introduction: Anaemia, a multifactorial health challenge has been found to affect every stage of human development with negative health impacts. Providing information on the factors associated with Anaemia will help in formulating mitigating strategies against this important public health problem. Objective: To determine the prevalence of Anaemia and its relationship with body mass index (BMI) and sociodemographic characteristics in adult Nigerians in Ebonyi State, South-eastern Nigeria. Materials and Methods: Adults (n=428) aged ≥ 18 y (mean=38.4±13.7 y) randomly selected from 130 political wards from the 13 Local Government Areas of the state were studied. Sociodemographic data was collected with questionnaire while blood samples were collected for hemoglobin determination using colorimetric cyanmethemoglobin method. Data was analysed using statistical package for social sciences (SPSS® for Windows® ver. 16). Results: In general, 21.7% of the subjects were anemic with Anaemia prevalence of 9.9%, 15.8% and 39.8% in male, non-pregnant and pregnant female, respectively. About four percent (3.7%) of the subjects were underweight, while 37.6% had excess weight with hemoglobin concentration having no relationship with BMI and sociodemographic parameters. Conclusion: It may be conclude that the Anaemia in adult Nigerians in Ebonyi State has no definite relationship with BMI and sociodemographic characteristics studied. Further studies are needed to document other factors that may be associated with Anaemia among adults in the State. PMID:25738011

    Background: The aim of this study is to determine the plasma levels of interleukin 6 (IL-6), tumor necrotic factor alpha (TNF-α, and C-reactive protein (CRP) in adult Nigerians with the metabolic syndrome and to determine the relationship between components of the metabolic syndrome and CRP in adult Nigerians. Subjects and Methods: This was a case–control study of fifty adult men and women with the metabolic syndrome, and fifty age- and sex-matched males and females without the metabolic syndrome. Metabolic syndrome was defined based on the National Cholesterol Education Programme-Adult Treatment Panel III criteria. Written informed consent was obtained from the participants. Blood pressure and anthropometry measurements were taken and venous blood was collected after an overnight fast. The Ethics Committee of the Lagos University Teaching Hospital, Lagos, Nigeria, approved the study protocol. Comparisons of continuous variables and categorical variables were done using the Student's t-test and Chi-square test, respectively. Regression analysis was used to determine the associations between variables. Statistical significance was set at P< 0.05. Results: The age- and sex-matched males and females with and without the metabolic syndrome did not differ in their sociodemographic characteristics. They however differed in some clinical and laboratory parameters such as diastolic blood pressure (P = 0.048), waist circumference (P = 0.002), body mass index (P = 0.012), waist/hip ratio (P = 0.023), high density lipoprotein (HDL) (P = 0.012), and insulin resistance (IR) (P = 0.042). There was a statistically significant increase in the inflammatory marker, CRP (P = 0.019), the cytokines, IL6 (P = 0.040), and TNF-α (P = 0.031) between the subjects with and without metabolic syndrome. There was also a significant association between CRP, waist circumference, IR, and HDL in the metabolic syndrome (P < 0.05). Conclusion: Plasma levels of inflammatory cytokines are raised in

    Coadministration of nevirapine-based antiretroviral therapy (ART) and artemether-lumefantrine is reported to result in variable changes in lumefantrine exposure. We conducted an intensive pharmacokinetic study with 11 HIV-infected adults who were receiving artemether-lumefantrine plus nevirapine-based ART, and we compared the results with those for 16 HIV-negative adult historical controls. Exposure to artemether and lumefantrine was significantly lower and dihydroartemisinin exposure was unchanged in subjects receiving nevirapine-based ART, compared with controls. Nevirapine exposure was unchanged before and after artemether-lumefantrine administration. PMID:26392500

    Cannabis is the most widely used illicit drug among adolescents and young adults. Despite its widespread use, only a few reports exist on the association of cannabis use and stroke. A 26-year-old Nigerian male, developed right-sided ischemic stroke few hours after smoking three wraps of cannabis. He had smoked cannabis consistently for the past 4 years prior to the development of the stroke. Known stroke etiology and abuse of other illicit drugs were ruled out from history and investigations. Neuroimaging studies of the brain revealed infarcts in basal ganglia secondary to occlusion of blood flow in the left anterior and middle cerebral arteries. The mechanism of stroke in this patient was thought to be a cannabis-induced vasculopathy. Many cases of stroke in the young are increasingly being seen in hospitals in resource scarce countries. There seems to be a predilection for the basal ganglia in ischemic stroke following cannabis abuse. Therefore, cannabis abuse should be considered in young adults with basal ganglia infarcts, after excluding other known etiologies. PMID:25288854

    It is becoming increasingly evident that patients with diabetes do not rely only on prescription drugs for their disease management. The use of herbal medicines is one of the self-management practices adopted by these patients, often without the knowledge of their healthcare practitioners. This study assessed the potential for pharmacokinetic herb-drug interactions (HDIs) amongst Nigerian adult diabetic patients. This was done through a literature analysis of the pharmacokinetic profile of their herbal medicines and prescription drugs, based on information obtained from 112 patients with type-2 diabetes attending two secondary health care facilities in Nigeria. Fifty percent of the informants used herbal medicines alongside their prescription drugs. Worryingly, 60% of the patients taking herbal medicines did not know their identity, thus increasing the risk of unidentified HDIs. By comparing the pharmacokinetic profile of eight identified herbs taken by the patients for the management of diabetes against those of the prescription drugs, several scenarios of potential HDIs were identified and their clinical relevance is discussed. The lack of clinical predictors points toward cultural factors as the influence for herb use, making it more difficult to identify these patients and in turn monitor potential HDIs. In identifying these possible interactions, we have highlighted the need for healthcare professionals to promote a proactive monitoring of patients' use of herbal medicines. PMID:27559312

    The objective of this study was to assess the effectiveness of variable titration, low-dose intratympanic gentamycin (ITG) into the worse affected ear of patients with bilateral Meniere's disease (MD). It is a prospective analytic case series conducted in a tertiary care referral hospital in a developing economy and a tertiary care otologic private ENT clinic. Patients with MD who failed or are intolerant to medical treatment were recruited based on the criteria of definite MD and bilateral ear involvement. 0.75 cc of low-dose (40 mg/ml) buffered gentamycin was injected into the worse affected ear and patients followed up every 2 months, and the regime repeated only if subjective vertigo persists. The patient's age, sex, duration of MD symptom, ear first affected, ear selected for ITG, pure tone threshold at each visit, duration of caloric response (in seconds) for the injected ear, status of tinnitus in both ipsilateral (injected) and contralateral ears, total number of injections before last follow-up, and time since last follow-up are entered into the study protocol and analyzed. Nine patients with a mean age of 45 years and mean duration of symptoms of 59 months were treated. The mean total number of injections was 2.8 with a mean follow-up period of 34 months. Three cases showed drop in pure tone average threshold (2.5-7.5 dB) while an increase in threshold was noted in six cases (2.5-5 dB). All cases demonstrated decrease in duration of response to iced water caloric stimulation in ipsilateral ear, and 4/9 of contralateral ear. The variable titration method using low-dose intratympanic gentamycin directed at worse ear of adult Nigerians with bilateral Meniere's disease appears to be highly effective. More studies are needed.

    The prevalence of kidney diseases is on the increase in Nigeria. The cost of its management is far beyond the reach of an average patient. Prevention is thus of paramount importance and awareness of kidney diseases will help in its prevention. The aim of this study is to assess the level of awareness of kidney functions and diseases among adults in a Nigerian population. A semi-structured, researcher - administered questionnaire was the tool for data collection. Four hundred and thirty-five questionnaires were analyzed. There were 160 males (36.8%) and 275 females (63.2%). The mean age was 42.8 ± 14 years with a range of 18-78 years. Among these, 82.1% were aware of the kidneys' involvement in waste removal from the body through urine while 36% and 29% were aware of kidneys' role in blood pressure regulation and blood production, respectively. Only 26.6% correctly identified at least two basic functions of the kidneys. Also, 32.6% of the respondents were aware of at least three common causes of kidney diseases in our environment. Majority of the respondents (70.7%) did not know that kidney diseases could be inherited. Furthermore, belief in alternative therapy for kidney disease was documented in 83.2%, while unawareness of dialysis as a treatment modality was recorded in 68% of the respondents. The awareness of kidney functions and diseases among the population is poor. Measures are needed to improve this to stem the rising prevalence of chronic kidney disease in Nigeria.

    This study investigates the prevalence of weight misperception, weight preference, and body shape dissatisfaction (BSD) among young-adult Nigerians and assesses the impact of these factors on population quality-of-life (QOL). Relevant anthropometric data were collected according to internationally accepted protocols. Weight perception, weight preference, and BSD were measured using Stunkard silhouettes, while QOL was determined by subjective self-reporting. The results show that 26.7% of the population (18.8% for males and 34.5% for females) misperceived their weight. Among overweight participants, 56.6% (males) and 38.3% (females) thought they were thinner, while 11.5% (males) and 43.3% (females) thought they were heavier. Thin and obese males misperceived their weights more than their female counterparts. BSD was found in 62% of the population (52% for males and 71% for females) and was highest among obese participants (91.9%) and lowest among normal-weight participants (58.2%), irrespective of sex. In participants with BSD, QOL was worse in thin and normal-weight respondents who preferred to be heavier and in overweight respondents who preferred to be thinner. The high prevalence of weight misperception may lead to inappropriate weight loss habits, while BSD, a normative discontent in this population, negatively impacts subject QOL. PMID:26232703

    Background: The aim of this study was to determine the relationship between the concentration of volatile sulphur compounds (VSC) in mouth air and the severity of periodontal diseases in young adults. Materials and Methods: A total of 400 subjects were studied. Estimation of periodontal disease severity was done using the basic periodontal examination (BPE) and the baseline measurement of the concentration of VSC in the mouth air of the subjects was done objectively using the Halimeter®. Result: The mean concentration of VSC for the group with BPE code 0 was 91.0 ± 5.9 parts per billion (ppb), 156.4 ± 9.4 ppb for BPE code 1, 275.2 ± 38.5 ppb for BPE code 2, 353.5 ± 72.3 ppb for BPE code 3, and 587.0 ± 2.1 ppb for BPE code 4 (P = 0.001). Majority (79.0%) of the subjects with BPE code 0 had concentration of VSC <181 ppb. Sixty-two (54.9%) with BPE code 1 had concentration of VSC <181 ppb, 34% with BPE code 2 had concentration of VSC <181 ppb and 42.9% with BPE code 3 had concentration of VSC <181 ppb. Only 6.5% of the subjects with BPE code 0 had VSC concentration >250 ppb, whereas all (100%) of those with BPE code 4 had VSC concentration >250 ppb (P = 0.001). Conclusion: It was concluded that a relationship exists between the periodontal pocket depth and the concentration of VCS in mouth air of young adults. PMID:23901175

    Background: Hepatitis-B infection is not commonly perceived as a serious medical problem in Nigeria. However, chronic hepatitis-B infection, which is a subject of global concern, may lead to lethal liver diseases. Aim: The study was to determine the sero-epidemiology of hepatitis-B surface antigenaemia among adult Nigerians with clinical features of liver diseases attending a primary-care clinic in a resource-constrained setting of Eastern Nigeria. Materials and Methods: A cross-sectional study was carried out on 140 adult Nigerians with clinical features of liver diseases at the primary-care clinic of Federal Medical Centre, Owerri. They made up three groups: 44 patients, 62 patients and 34 patients with clinical features of hepatitis, liver cirrhosis and hepatocellular carcinoma, respectively. Hepatitis-B surface antigen (HBsAg) was assayed using an immunochromatographic method. Demographic variables were collected. Results: The overall sero-positivity rate was 50.7%. The sero-positivity rates for these patients were 23.9%, 39.5% and 36.6% for hepatitis, liver cirrhosis and hepatocellular carcinoma, respectively. The age group 40-60 years (P = 0.048) and artisans (P = 0.019) were significantly infected. Abdominal swelling (86.4%) and ascites (67.1%) were the most common symptoms and signs, respectively. Conclusion: HBsAg prevalence was high and has significant association with age and occupation. PMID:23724405

    The characteristics of visually guided saccadic eye movements were compared in 12 normal adult subjects and 12 test subjects of normal intelligence, but with problems in reading and writing. All subjects were examined psychometrically for different cognitive abilities, and for their reading and writing capabilities. The anamnestic reports about their reading and writing problems earlier in their lives were analysed. Based on scores of the writing and reading tests, the test group was subdivided into two subgroups: A and B (group A reached medium, group B very low scores in both tests). Five different non-cognitive eye movement tasks were applied: two single tasks (gap and overlap) requiring single saccades from a fixation point to a peripherally appearing target and three sequential tasks (overlap, synchronous, and simultaneous) requiring sequences of saccades to four equally spaced targets presented sequentially to the right side from an initial fixation point. Many parameters of the subjects' eye movement performance were determined and their mean values were calculated for each subject. The Student t-test revealed that the eye movement data of the two test groups deviated differently from the data of the control group. Group B had the largest deviation of the eye movement parameter from the control group. The differentiating parameters were the consistency of target acquisition, the saccadic reaction time, and the number of anticipatory responses in the single target tasks. In the sequential tasks these differences were in the amplitude, the number of saccades, and the fixation durations. The incidence of regressive saccades did not discriminate between test subjects and controls. The possible underlying deficits in the attentional control over the saccadic system and their implications for reading are discussed.

    Screening for Schistosoma haematobium infection and its possible morbidity was carried out in 257 adult participants in Eggua community, Ogun State, Nigeria. Parasitological assessment for the presence of ova of S. haematobium in urine and abdominopelvic ultrasonographic examination for bladder and secondary kidney pathology were carried out. S. haematobium prevalence of 25.68% (66/257) was recorded among the participants. There was a significantly higher prevalence of 69.2% of urinary schistosomiasis in the females than the prevalence of 31.8% in males (P = 0.902). The intensity of infections was mostly light (55) (21.8%) compared to heavy (10) (3.9%) with the mean intensity of 16.7 eggs/10 mL urine. Structural bladder pathology prevalence among participants was 33.9%. The bladder and kidney pathologies observed by ultrasound in subjects with S. haematobium infections included abnormal bladder wall thickness (59%), abnormal bladder shape (15.2%), bladder wall irregularities (15.2%), bladder masses (1.5%), bladder calcification (1.5%), and hydronephrosis (3%). Infection with S. haematobium was associated with bladder pathology. Higher frequencies of bladder abnormalities were observed more in the participants with light intensity of S. haematobium infection than in those with heavy infection. More bladder pathology was also seen in women than in men, although this was not statistically significant. In conclusion, there is evidence that the development of bladder pathology may be associated with S. haematobium infection. PMID:27635146

    Left ventricular hypertrophy (LVH) is considered an independent risk factor even in the absence of systemic hypertension. Electrocardiographic (ECG) LVH with repolarisation changes has been found in some countries to carry more coronary risk than LVH alone. How far this observation is true among adult Nigerians is not known. We therefore decided to study adult Nigerians with ECG-LVH with or without ST-T waves changes and compare them with normal age matched controls (without ECG-LVH) in relation with established modifiable risk factors such as systemic hypertension (BP), body mass index (BMI), fasting blood sugar (FBS) and serum lipids such as total cholesterol (Tc), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Adult Nigerians who were consecutively referred to the ECG laboratory were randomly recruited. Three hundred patients were studied. Their blood pressures (BP) as well as body mass indices were recorded after recording their resting 12 read ECG using portable Seward 9953 ECG machine. Their waist-hip ratio (WHR) was also recorded. Blood samples were taken to determine their fasting blood sugar and serum lipids. Their ECG tracings were read by the cardiologists involved in the study while the blood samples were analysed by the chemical pathologist also involved in the study. At the end of the ECG reading, the patients were divided into 3 groups according to whether there was no ECG-LVH (control group A), ECG-LVH alone (group B), and ECG-LVH with ST-T waves changes (group C). One hundred and fifty (50%) patients belonged to group A, 100 (33.3%) patients to group B and 50 (16.7%) group C. Group B patients were found to have higher modifiable risk factors in form of systemic BP. Tc, LDL-C, and WHR compared to group A. However, the group C patients had increased load of these coronary risk factors in terms of BP elevation, higher BMI, FBS, and scrum cholesterol compared to group B. In addition

    2010-07-01

    Lifetime prevalence, incidence, and risk factors for parasomnias were determined. Past experiences of non-REM, REM, and sleep-transition parasomnias were recorded. Diaries of night sleep duration, parasomnias, perception of aliens, levels of physical activity, headaches and intake of all substances, drugs, and tobacco were kept for 14 consecutive days. A total of 276 subjects were studied. Lifetime prevalences (95% CI) were 725 (668-776) for occurrence of any parasomnia, 43 (25-74) for sleepwalking, 112 (80-155) for sleep terror, 475 (416-533) for nightmares, 225 (179-277) for sleep paralysis, 43 (25-74) for sleep starts, 322 (270-380) for sleep talking, and 344 (291-402) for enuresis. Incidences (95% CI) were 210 (166-262) for occurrence of any parasomnia, 14 (6-37) for sleepwalking, 11 (4-31) for sleep terror, 170 (131-219) for confusional arousal, 18 (8-42) for nightmares, 14 (6-37) for sleep paralysis, 33 (17-61) for sleep starts, and 4 (1-20) for sleep enuresis. Multivariate analysis showed associations of increase occurrence of parasomnias and duration of sleep >7 h (p < 0.05) and intake of alcohol (p < 0.001), but heavy workload before sleep was associated with decreased occurrence of parasomnias (p < 0.01). Gender, smoking, caffeinated drinks, hypnotics, and headaches were not associated with parasomnias. Incidence of presence of aliens (95% CI) in the room was 25(0/infinity) (12-51). This study shows that more than 70% of the population have experienced parasomnias at any time in the past. Nightmares, enuresis, sleep paralysis and night terrors are the commonest parasomnias experienced in the past, while confusional arousal, sleep starts, and nightmares are the commonest parasomnias currently experienced. Incidence estimates show that all parasomnias persist into adulthood at reduced rates, but reduction of occurrence was greatest for enuresis. Long duration of night sleep and intake of alcohol predisposed subjects to higher occurrence of parasomnias. PMID

    2013-01-01

    Background: Obesity once thought the medical problem of affluent countries now exist in Nigeria and has been described as a time bomb for the future explosion in the frequency of cardio-metabolic diseases. The most deleterious health consequences of obesity are on the cardiovascular system and associated disorder of lipid and glucose homeostasis. Aim: This study was designed to determine the magnitude of obesity and its cardio-metabolic co-morbidities among adult Nigerians in a primary care clinic of a tertiary hospital South-Eastern, Nigeria. Materials and Methods: A cross-sectional study carried out on 2391 adult Nigerians who were assessed for obesity using body mass index (BMI) criterion. 206 patients who had BMI ≥30kg/m2 were screened for cardio-metabolic co-morbidities. The data collected included basic demographic variables, weight, height, blood pressure; fasting plasma glucose and lipid profile. Results: The prevalence of obesity was 8.6%. Grade I obesity (67.5%) was the most common pattern; others included grade II obesity (23.3%) and grade III obesity (9.2%). Hypertension (42.7%) was the most common cardio-metabolic morbidity. Others included low HDL-cholesterol (22.8%), diabetes mellitus (15.1%), high triglyceride (12.6%), high total cholesterol (9.2%), and high LDL-cholesterol (6.8%). Conclusion: Obesity and its cardio-metabolic morbidities exist among the study population. Anthropometric determination of obesity and screening for its associated cardio-metabolic co-morbidities should constitute clinical targets for intervention in primary care clinics. PMID:24479038

    1975-01-01

    The Authors carried out a serological research on the polimyelitis viruses in 727 adult subjects who had not been vaccinated orally. The results of the titration of the neutralizing antibodies showed that the situation of immunity with respect to poliomyelitis is still satisfactory. However, the difficulty of making an exact estimation of the duration of the state of immunity to poliomyelitis, and the persistent, though reduced, circulation of wild polioviruses are such that a continuous epidemiological control is advisable.

  10. Alteration of adults' subjective feeling of familiarity toward infants' sounds.

    2008-08-01

    Many adults may have lower subjective feelings of familiarity toward infants' vocalizations since infants' sounds are different from those of adults. However, mothers frequently exposed to infants' vocalizations may be more familiar and less averse. To test this hypothesis, 21 mothers (M age = 31.1 yr., SD = 4.3) of infants (M age = 8.2 mo., SD = 3.5), 18 mothers (M age = 34.4 yr., SD = 4.8) of children between two and five years of age (M age = 2.8 yr., SD = 1.0), and 17 women (M age = 29.2 yr., SD = ll.1) with no children were exposed to 20 types of sounds. Of these sounds, 14 were produced by infants. Although the mothers of infants did not recognize sounds as those of an infant's vocalization, they showed higher subjective feelings of familiarity toward the timbres of the vowel-like stimuli than did the other groups. By contrast, the subjective feelings of familiarity for nonspeech sounds did not differ among groups. Maternal experiences may change women's recognition of perceived sounds.

    2015-07-01

    We investigate determinants of subjective social status (SSS) as measured by respondents placing themselves on a ten-rung ladder from least to most "money", "education" and "respected job", in a large sample of young adults. The most potent clues of SSS are proximate in the life course, reflecting educational attainment and current socioeconomic and job situation, rather than distal characteristics such as family background, although relatively distal High school GPA has a lingering effect. Additional analyses reveal that College selectivity has a substantial impact on SSS, net of other variables in the model; Currently married does not significantly contribute to SSS, but contrary to some expectations Number of children significantly lowers SSS. We find no evidence of greater "status borrowing" by women as associations of SSS with shared household characteristics (Household income, Household assets, Home ownership) do not differ by gender. Our findings for these young adults support the conclusion of earlier research that SSS reflects a "cognitive averaging" of standard dimensions of socioeconomic status. PMID:26004468

    Ehizele, AO; Akhionbare, O

    2013-01-01

    Background: The major goal of non-surgical periodontal therapy is to reduce or eliminate the subgingival pathogenic microbial flora that is known to be associated with volatile sulfur compounds (VSC). Aim: The aim of this study was, therefore, to determine the effect of non-surgical periodontal therapy on the concentration of VSC in mouth air of young adults. Subjects and Methods: Four hundred subjects, grouped into two based on the absence or presence of periodontal diseases, were involved in this study. Basic periodontal examination was used for the grouping. The measurement of the concentration of the VSC in the mouth air of the subjects was done objectively, using the Halimeter, before and after the therapy, and at recall visits 2 weeks and 6 weeks after therapy. Chi-square and Paired t-test were used to find statistical significance. Results: The results revealed that at baseline, 78.7% (48/61) of the subjects who had VSC concentration more than 250 parts per billion (ppb) were from the group with periodontal disease. Immediately after non-surgical periodontal therapy, only 8.5% (17/200) of the subjects with periodontal disease had VSC concentration of more than 250 ppb while all the subjects with no periodontal disease had VSC concentration less than 181 ppb. The same pattern of reduction in the concentration of the VSC and improvement in oral hygiene was also obtained 2 weeks and 6 weeks after therapy. Conclusion: It can be concluded that non-surgical periodontal therapy brought about reduction in the concentration of volatile sulfur compounds in mouth air of young adults. PMID:24116328

    1989-01-01

    This study reviews clinical studies testing the effects of various doses of aspartame on blood levels of phenylalanine, aspartate, and methanol in normal subjects and known phenylketonuric heterozygotes. The effect of aspartame on the phenylalanine-to-large neutral amino acid ratio under various feeding situations is shown. The clinical studies of aspartame in diabetic subjects are limited to observations of its effects on blood levels of glucose, lipids, insulin, and glucagon. These studies clearly demonstrate the safety of this high-intensity sweetener for use by humans.

    2016-03-01

    Subjective assessment may be incomparable across countries due to differences in reporting styles. Based on two nationally representative surveys from the US and China, this study used data from three anchoring vignettes to estimate to what extent the US and Chinese older adults aged 50 and above differed in their reporting styles of subjective cognitive impairment. Cross country differences of subjective cognitive impairment were then estimated, both before and after adjusting for reporting heterogeneity. Directly assessed word recall test scores were analyzed to evaluate whether findings based on subjective cognitive impairment was consistent with objective performance. The results revealed a discrepancy between self-reported subjective cognitive impairment and directly assessed memory function among older adults: while Chinese respondents reported lower severity levels of subjective cognitive impairment, the US respondents demonstrated better performance in immediate word recall tests. By accounting for differences in reporting styles using anchoring vignettes data, Chinese older adults showed higher levels of subjective cognitive impairment than the US older adults, which was consistent with results from direct assessment of memory function. Non-negligible differences are present in reporting styles of subjective cognitive impairment. Cross country comparison needs to take into account such reporting heterogeneity.

    2011-02-01

    Research on subjective well-being suggests that it is only partly a function of environmental circumstances. There may be a personality characteristic or a resilient disposition toward experiencing high levels of well-being even in unfavorable circumstances. Adult attachment may contribute to this resilient disposition. This study examined whether the association between attachment anxiety and subjective well-being was mediated by Neff's (2003a, 2003b) concept of self-compassion. It also examined empathy toward others as a mediator in the association between attachment avoidance and subjective well-being. In Study 1, 195 college students completed self-report surveys. In Study 2, 136 community adults provided a cross-validation of the results. As expected, across these 2 samples, findings suggested that self-compassion mediated the association between attachment anxiety and subjective well-being, and emotional empathy toward others mediated the association between attachment avoidance and subjective well-being.

    Data from 2 pediatric single-dose studies, conducted at the same center, were combined to evaluate exposure levels of bupropion and metabolites in adolescents 12-17 years old, compared with adults > 18 years. Pharmacokinetic analyses of bupropion and its metabolites were performed using normalization and pharmacological/convulsive weighting methods on exposure. When compared with adults (>18 years), subjects 12-14 years had an increase in weight-normalized exposure to bupropion (ie, Cmax , 78%; AUC0-t , 83%; and AUCinf , 85%). Variability in this younger age group was also higher, with observations of a 3- to 4-fold increase in exposure. When the changes in metabolites were accounted within pharmacological and convulsive-weighted exposures, the relative ratio of 12-14 years to adults in body weight-normalized Cmax was 127% and 110%, respectively. Subjects 15-17 years did not exhibit a difference in exposure compared with adults. The influence of age on bupropion pharmacokinetics demonstrates that, in general, healthy adolescent subjects cannot be considered smaller healthy adult subjects; the increase in exposure is inversely related to age and appears to be solely associated with bupropion, not with its metabolites. Because there are no clinical safety and efficacy data of bupropion in adolescents, this data may shift its risk-benefit profile. PMID:27137143

    2011-01-01

    Older adults are increasingly the intended target of direct-to-consumer (DTC) prescription drug ads, but limited evidence exists as to how they assess the educational value of DTC ads and, more importantly, whether their assessment depends on their level of health literacy. In-person interviews of 170 older adults revealed that those with low subjective health literacy evaluated the educational value of DTC ads significantly lower than did those with high subjective health literacy. The results prompt us to pay more scholarly attention to determining how effectively DTC ads convey useful medical information, particularly to those with limited health literacy.

    2016-03-30

    Loneliness and depressive symptoms are closely related, and both are indicators of reduced physical and mental well-being in old age. In recent years, the subjective perception of how long an individual expects to live (subjective life expectancy) has gained importance as a significant predictor of future psychological functioning, as well as of physical health. The current study examined whether subjective life expectancy moderates the connection between loneliness and depressive symptoms in a representative sample of older adults. Data was collected from the Israeli component of the fifth wave of the Survey of Health, Ageing and Retirement in Europe (SHARE-Israel). Participants (n=2210; mean age=70.35) completed measures of loneliness, depressive symptoms, and life expectancy target age. A hierarchical regression analysis predicting depressive symptoms yielded a significant interaction of loneliness and subjective life expectancy. Further analyses demonstrated that low subjective life expectancy mitigated the loneliness-depressive symptoms connection. Findings are discussed in light of the potential burden of higher subjective life expectancy for lonesome older adults, and practical implications are suggested.

    Research on the relationship between habitual sleep patterns and memory performance in older adults is limited. No previous study has used objective and subjective memory measures in a large, older-aged sample to examine the association between sleep and various domains of memory. The aim of this study was to examine the association between objective and subjective measures of sleep with memory performance in older adults, controlling for the effects of potential confounds. One-hundred and seventy-three community-dwelling older adults aged 65-89 years in Victoria, Australia completed the study. Objective sleep quality and length were ascertained using the Actiwatch 2 Mini-Mitter, while subjective sleep was measured using the Pittsburgh Sleep Quality Index. Memory was indexed by tests of retrospective memory (Hopkins Verbal Learning Test - Revised), working memory (n-back, 2-back accuracy) and prospective memory (a habitual button pressing task). Compared with normative data, overall performance on retrospective memory function was within the average range. Hierarchical regression was used to determine whether objective or subjective measures of sleep predicted memory performances after controlling for demographics, health and mood. After controlling for confounds, actigraphic sleep indices (greater wake after sleep onset, longer sleep-onset latency and longer total sleep time) predicted poorer retrospective (∆R(2)  = 0.05, P = 0.016) and working memory (∆R(2)  = 0.05, P = 0.047). In contrast, subjective sleep indices did not significantly predict memory performances. In community-based older adults, objectively-measured, habitual sleep indices predict poorer memory performances. It will be important to follow the sample longitudinally to determine trajectories of change over time. PMID:26868539

    This article describes a study that assesses body fat distribution patterns in Nigerian and African-American males and females and determines the association between body fat distribution patterns and blood pressure in young adults of differing geographical and ethnic backgrounds. The study population was comprised of 275 African Americans (92 males and 183 females) and 282 Nigerians (219 males and 63 females). The mean ages for the African-American males and females were 18.7 and 18.9 years, respectively, compared with 21 and 19.2 years for the Nigerian males and females. African Americans were more likely to be obese and overweight compared with their Nigerian counterparts. However, there were no significant differences between the two ethnic groups within gender for body fat distribution patterns based on waist-to-hip ratio. Despite being leaner, the Nigerians had higher diastolic blood pressures than the African Americans. There were no significant associations observed between blood pressure and waist-to-hip ratio for either the Nigerian or the African-American males or females, and body mass index was associated consistently with blood pressure only among the African Americans. These findings suggest that body mass index, a general indicator of obesity, is a better correlate of blood pressure than the waist-to-hip ratio among African Americans. PMID:8151724

    The past 15 years have seen an increasing governmental and corporate concern for the environment worldwide. For governments, information about the environmental performance of the industrial sector is required to inform macro-level decisions about environmental targets such as those required to meet UN directives. However, in many African, Asian, and Latin American countries, researching and reporting company environmental performance is limited. This article serves as a contribution to filling the gap by presenting evidence of physical and chemical risk in Nigerian factories. One hundred and three factories with a total of 5,021 workers were studied. One hundred and twenty physical and chemical hazards were identified and the result shows a high number of workers exposed to such hazards. The study also reveals that workers' awareness level of chemical hazards was high. Yet the danger was perceived in behavioral terms, especially by manufacturing firms, which tend to see environmental investment in an increasingly global economy as detrimental to profitability.

    Background Body mass index (BMI) is associated with subjective well-being. Higher BMI is believed to be related with lower well-being. However, the association may not be linear. Therefore, we investigated whether a nonlinear (U-shaped) trend would better describe this relationship, and whether eating disorders might account for the association in young adults. Methods FinnTwin16 study evaluated multiple measures of subjective well-being, including life satisfaction, General Health Questionnaire (GHQ-20), satisfaction with leisure time, work, and family relationships, and satisfaction with sex life in young adulthood in the 1975–79 birth cohorts of Finnish twins (n=5240). We studied the relationship between indicators of subjective well-being and BMI both in full birth cohorts and in subgroups stratified by lifetime DSM-IV eating disorders. Results We found an inverse U-shaped relationship between all indicators of subjective well-being and BMI in men. There was no overall association between BMI and subjective well-being in women. However, there was an inverse U-shaped relationship between BMI and indicators of subjective well-being in women with a lifetime eating disorder and their healthy female co-twins. Subjective well-being was optimal in the overweight category. Conclusions Both underweight and obesity are associated with impaired subjective well-being in young men. The BMI reflecting optimal subjective well-being of young men may be higher than currently recognized. Categorization of body weight in terms of BMI may need to be reassessed in young men. BMI and subjective well-being are related in women with a lifetime eating disorder, but not in the general population of young women. PMID:23496885

    Background. Older adults report subjective memory complaints (SMCs) but whether these are related to depression remains controversial. In this study we investigated the relationship between the SMCs and depression and their predictors in a sample of old adults. Methods. This cross-sectional study enrolled 620 participants aged 55 to 96 years (74.04 ± 10.41). Outcome measures included a sociodemographic and clinical questionnaire, a SMC scale (QSM), a Geriatric Depression Scale (GDS), a Mini-Mental Status Examination (MMSE), and a Montreal Cognitive Assessment (MoCA). Results. The QSM mean total score for the main results suggests that SMCs are higher in old adults with depressed symptoms, comparatively to nondepressed old adults. The GDS scores were positively associated with QSM but negatively associated with education, MMSE, and MoCA. GDS scores predicted almost 63.4% of variance. Scores on QSM and MoCA are significantly predicted by depression symptomatology. Conclusion. Depression symptoms, lower education level, and older age may be crucial to the comprehension of SMCs. The present study suggested that depression might play a role in the SMCs of the older adults and its treatment should be considered. PMID:26880907

    2009-05-01

    Subjective and objective measures of quality of life (QoL) were obtained for adults with autism spectrum disorders (ASDs) living in Andalusia (Spain). Seventy-four families responded to questionnaires about objective QoL indicators such as employment, health, adaptive behaviour and social network, and were asked to act as proxies for subjective QoL measures. Outcome on objective QoL was extremely poor. Social networks were most frequently composed of family members. Community-oriented resources were absent in most cases. For two-thirds of the families, the ability to act as proxies for subjective QoL was seriously limited by the participants' poor social and communicative abilities. The results are indicative of the need for additional support to families of adults with ASD and increased community-based resources. Further conceptualization of indicators and measurement of subjective QoL in individuals with severe disabilities and ASD is also needed in order to include their own perspective in the evaluation of service provision.

  19. Subject-verb agreement in children and adults: serial or hierarchical processing?

    Two processes, serial and hierarchical, are generally opposed to account for grammatical encoding in language production. In a developmental perspective, the question addressed here is whether the subject-verb agreement during writing is computed serially, once the words are linearly ordered in the sentence, or hierarchically, as soon as the number features are determined in a hierarchical frame. Adults and children from 3rd to 5th grades were requested to listen to sentences with built-in prepositional phrases or relative clauses and to transcribe them as quickly as possible. A serial hypothesis assumes that subject-verb agreement errors should be equally frequent with both preambles because each has the same length separating the subject head noun and the main verb. Conversely, according to a hierarchical view, errors should be more frequent with a prepositional phrase because the syntactic distance between the subject and the verb is greater than with a relative clause. The results revealed a main effect of the preamble manipulated in 5th graders and adults, but not in 3rd graders. These data were in favor of a hierarchical processing in older writers and a serial one in younger children. However, in 3rd grade, we assumed that the potential serial account was a result of the resource constraint on writing more than of a real serial processing of the agreement. PMID:16050444

    2012-01-01

    This article investigates how personality and cognitive ability relate to measures of objective success (income and wealth) and subjective success (life satisfaction, positive affect, and lack of negative affect) in a representative sample of 9,646 American adults. In cross-sectional analyses controlling for demographic covariates, cognitive ability, and other Big Five traits, conscientiousness demonstrated beneficial associations of small-to-medium magnitude with all success outcomes. In contrast, other traits demonstrated stronger, but less consistently beneficial, relations with outcomes in the same models. For instance, emotional stability demonstrated medium-to-large associations with life satisfaction and affect but a weak association with income and no association with wealth. Likewise, extraversion demonstrated medium-to-large associations with positive affect and life satisfaction but small-to-medium associations with wealth and (lack of) negative affect and no association with income. Cognitive ability showed small-to-medium associations with income and wealth but no association with any aspect of subjective success. More agreeable adults were worse off in terms of objective success and life satisfaction, demonstrating small-to-medium inverse associations with those outcomes, but they did not differ from less agreeable adults in positive or negative affect. Likewise, openness to experience demonstrated small-to-medium inverse associations with every success outcome except positive affect, in which more open adults were slightly higher. Notably, in each of the five models predicting objective and subjective success outcomes, individual differences other than conscientiousness explained more variance than did conscientiousness. Thus, the benefits of conscientiousness may be remarkable more for their ubiquity than for their magnitude. PMID:23162483

    Discrepancy between subjective and objective measures of sleep is associated with insomnia and increasing age. Cognitive behavioural therapy for insomnia improves sleep quality and decreases subjective-objective sleep discrepancy. This study describes differences between older adults with insomnia and controls in sleep discrepancy, and tests the hypothesis that reduced sleep discrepancy following cognitive behavioural therapy for insomnia correlates with the magnitude of symptom improvement reported by older adults with insomnia. Participants were 63 adults >60 years of age with insomnia, and 51 controls. At baseline, participants completed sleep diaries for 7 days while wearing wrist actigraphs. After receiving cognitive behavioural therapy for insomnia, insomnia patients repeated this sleep assessment. Sleep discrepancy variables were calculated by subtracting actigraphic sleep onset latency and wake after sleep onset from respective self-reported estimates, pre- and post-treatment. Mean level and night-to-night variability in sleep discrepancy were investigated. Baseline sleep discrepancies were compared between groups. Pre-post-treatment changes in Insomnia Severity Index score and sleep discrepancy variables were investigated within older adults with insomnia. Sleep discrepancy was significantly greater and more variable across nights in older adults with insomnia than controls, P ≤ 0.001 for all. Treatment with cognitive behavioural therapy for insomnia was associated with significant reduction in the Insomnia Severity Index score that correlated with changes in mean level and night-to-night variability in wake after sleep onset discrepancy, P < 0.001 for all. Study of sleep discrepancy patterns may guide more targeted treatments for late-life insomnia.

    Objective: The objective of this study was to determine the safety of oral Polypodium leucotomos extract administered twice daily to healthy adults for 60 days and assess its ability to provide protection against exposure to ultraviolet radiation. Design: This was a randomized, double-blind, placebo-controlled study. Setting: A single clinical research center. Participants: Healthy adult men and women between 18 and 65 years of age with Fitzpatrick skin types I to IV. Measurements: Safety assessments included a physical examination, vital signs, and clinical laboratory parameters including hematology, comprehensive metabolic panel, and prothrombin time-partial thromboplastin time were obtained at baseline and at the end of the study. Reports of adverse events were recorded. Efficacy assessments were changes in minimal erythema dose testing, ultraviolet-induced erythema intensity response, and sunburn history during the prior 60 days. Results: After two months of treatment, there were no changes in any safety assessments. The subjects in the placebo group showed a greater likelihood of experiencing >1 episodes of sunburn (2 vs. 8 subjects; p=0.04) At Day 28, Polypodium leucotomos extract-treated subjects showed greater likelihood of an increased minimal erythema dose (8 vs. 1 subject; p=0.01) and greater likelihood of decreased ultraviolet-induced erythema intensity (10 subjects vs. 3 subjects; p<0.01). Conclusion: Polypodium leucotomos extract 240mg taken twice daily for 60 days was a safe and effective means for reducing the damaging effects of ultraviolet radiation. Based on the excellent safety profile of Polypodium leucotomos, additional studies using higher doses may be warranted. PMID:25741399

  5. The interplay of subjective social status and essentialist beliefs about cognitive aging on cortisol reactivity to challenge in older adults.

    Older adults are more likely than younger adults to experience stress when confronted with cognitive challenges. However, little is known about individual differences that might explain why some older adults exhibit stronger stress responses than others. We examined the interplay of two social-cognitive factors to explain older adults' cortisol reactivity: (1) subjective social status, and (2) essentialist beliefs about cognitive aging. We hypothesized that, depending on whether older adults believe that aging-related cognitive decline is inevitable versus modifiable, low subjective social status should lead to stronger or weaker cortisol reactivity. Using longitudinal data, we assessed the impact of cognitive challenges on stress reactivity in a sample of older adults (N = 389; 61-86 years). As predicted, regression analyses confirmed that 44 min after cognitively challenging tasks, older adults exhibited a significantly different cortisol reactivity depending on their subjective social status and their essentialist beliefs about cognitive aging. Specifically, older adults with low subjective social status and high essentialist beliefs showed a significantly elevated cortisol reactivity. We discuss the role of essentialist beliefs about cognitive aging to predict when and why high versus low subjective social status leads to stress responses in older adults.

    Background Saliva contains a large number of biomolecules, some of which have putative diagnostic usefulness. A potential problem with the use of biomolecules in diagnosis is day-to-day fluctuation due to within-subject variability. This study evaluated the intraindividual variability of six salivary analytes in healthy adults and determined their normal range. Methods Unstimulated whole saliva (5 ml) was collected every 2 to 3 days on six occasions from 30 subjects in good oral and systemic health. Four of the samples were collected in the clinic, and two were collected by the subject at home. The concentration ranges of interleukin (IL)-1β, IL-6, matrix metalloproteinase-8, prostaglandin E2, tumor necrosis factor-alpha, interferon-alpha, and albumin were examined. Descriptive statistics were computed, and a one-way random-effects model was used to quantify within- and between-subject components of variability. Intraclass correlation coefficients (ICCs) were calculated for each subject/analyte combination. Results Within-subject coefficients of variation for these analytes ranged from 67.6% to 172.1% for the in-clinic samples and from 111.9% to 201.0% for the at-home samples. The ICC for the various analytes ranged from 41% to 61% for the in-clinic samples. The at-home samples exhibited significantly more variability than did those obtained in the clinic under supervision. Conclusions There was marked within-subject variation in the salivary concentrations of these analytes. With increased interest in salivary diagnostics, the within-subject variability, normal range, and threshold levels for abnormal levels of individual salivary analytes need to be determined if these diagnostics tests are to have clinical usefulness.

    Objectives. To estimate the prevalence of subjective memory complaints (SMCs) in a sample of community-dwelling, older adults and to examine cognitive bases of these complaints. Participants. 499 community-dwelling adults, 65 and older. Measurements. A telephone survey consisting of cognitive tests and clinical and sociodemographic variables. SMCs were based on subjects' evaluations and subjects' perceptions of others' evaluations. Analysis. Logistic regression was used to model the risk for SMCs as a function of the cognitive, clinical, and sociodemographic variables. We tested for interactions of the cognitive variables with age, education, and gender. Results. 27.1% reported memory complaints. Among the younger age, better objective memory performance predicted lower risk for SMCs, while among the older age, better memory had no effect on risk. Among the better-educated people, better global cognitive functioning predicted lower risk for SMCs, while among the less-educated people, better global cognitive functioning had no effect on SMC risk. When predicting others' perceptions, better objective memory was associated with lower risk for SMCs. Conclusion. Objective memory performance and global cognitive functioning are associated with lower risk for SMCs, but these relationships are the strongest for the younger age and those with more education, respectively. Age and education may affect the ability to accurately appraise cognitive functioning. PMID:26317004

    The purpose of this study was to explore the subjective experience of older adults interacting with both virtual and real environments. Thirty healthy older adults engaged with real and virtual tasks of similar motor demands: reaching to a target in standing and stepping stance. Immersive tendencies and absorption scales were administered before the session. Game engagement and experience questionnaires were completed after each task, followed by a semi-structured interview at the end of the testing session. Data were analyzed respectively using paired t-tests and grounded theory methodology. Participants preferred the virtual task over the real task. They also reported an increase in presence and absorption with the virtual task, describing an external focus of attention. Findings will be used to inform future development of appropriate game-based balance training applications that could be embedded in the home or community settings as part of evidence-based fall prevention programs.

    Objective/Background: Sleep plays a central role in maintaining health and cognition. In most epidemiologic studies, sleep is evaluated by self-report questionnaires but several reports suggest that these evaluations might be less accurate than objective measures such as polysomnography or actigraphy. Determinants of the discrepancy between objective and subjective measures remain to be investigated. The aim of this pilot-study was to examine the role of mood states in determining the discrepancy observed between objective and subjective measures of sleep duration in older adults. Patients/Methods: Objective sleep quantity and quality were recorded by actigraphy in a sample of 45 elderly subjects over at least three consecutive nights. Subjective sleep duration and supplementary data, such as mood status and memory, were evaluated using ecological momentary assessment (EMA). Results: A significant discrepancy was observed between EMA and actigraphic measures of sleep duration (p < 0.001). The magnitude of this difference was explained by the patient’s mood status (p = 0.020). No association was found between the magnitude of this discrepancy and age, sex, sleep quality or memory performance. Conclusion: The discrepancy classically observed between objective and subjective measures of sleep duration can be explained by mood status at the time of awakening. These results have potential implications for epidemiologic and clinical studies examining sleep as a risk factor for morbidity or mortality. PMID:27507944

    The aim of this work was to assess the prevalence of palmar and axillary hyperhidrosis among young Polish adults. Additionally, this work aimed at comparing the subjective and objective (gravimetric) method of hyperhidrosis assessment. Healthy medical students, volunteering to take part in this study, were included. The participants filled out a questionnaire assessing the occurrence and subjective intensity of hyperhidrosis in different areas of the body. Additionally, the students were subjected to gravimetric assessment in four localizations: the face, palms, axillae and abdomino-lumbar area. Two hundred and fifty-three students (102 males and 151 females, mean age 24.3 ± 3.21 years) were included in the study. Forty-two (16.7%) participants declared that they suffer from hyperhidrosis. Out of the 42 students declaring any type of hyperhidrosis, only 20 (47.6%) exceeded the gravimetric reference values. From among the students that exceeded the normative values for palmar hyperhidrosis, only 10 (55.6%) were aware of their hyperhidrosis. In the group of students that exceeded the normative values for axillary hyperhidrosis, 16 (39%) were aware of their hyperhidrosis. Subjectively declared hyperhidrosis incidence may significantly exceed the real-life occurrence of this disease. Basing studies solely on data gathered from questionnaires, may lead to false results. It is imperative, when assessing patients suffering from hyperhidrosis, to use both objective and subjective methods of evaluation.

    1. Twenty apparently healthy and normal Nigerian male students, resident at the University of Ibadan campus, were studied for seven consecutive days to assess their food energy intake and expenditure and pattern of their daily activities. 2. The mean age (years) of the group was 24.0 (SD 3.23, range 20-30), mean height (m) 1.71 (SD 0.06, range 1.61-1.84) and body-weight (kg) was 61.1 (SD 5.01, range 51.0-69.5). 3. The food intake of each subject was obtained by direct weighing and its energy value determined using a ballistic bomb calorimeter. Patterns of daily activities were recorded and the energy costs of representative activities were determined by indirect calorimetry. 4. Activities mainly involved sitting, mean 580 (SD 167, range 394-732) min/d. Sleeping and standing activities took a mean of 445 (SD 112) and 115 (SD 75) min/d respectively. Personal domestic activities took a mean of 94 (SD 40) min/d. 5. The mean energy intake of the group was 11,182 (SD 1970) kJ/d or 183 (SD 32) kJ/kg body-weight per d. This value is lower than the 12.5 MJ/d recommended by the Food and Agriculture Organization (FAO)/World Health Organization (WHO) (1973) as the energy requirement for an adult man engaged in moderate activities, but it is higher than the FAO/WHO/United Nations University (UNU) (1985) recommended value of 10.8 MJ/d for a male office clerk (light activity). It is also lower than the recommended energy requirement of 11.6 MJ/d for a subsistence farmer (moderately active work) (FAO/WHO/UNU, 1985). 6. The mean energy expenditure of the male subjects was 9876 (SD 1064, range 7159-12,259) kJ/d and was lower than mean intake. 7. The energy intake and expenditure values indicated that the groups participating in the present study were not physically very active. It is an indication that the Nigerian male students expended less but probably consumed more energy than required. It is suggested for health reasons and for mental fitness that the Nigerian male students

    This article was designed to consider the congenital age-specific features of palm dermatoglyphics in the adults subjects (including the type of the papillary patterns, axial tri-radii, the termini of palmar main lines, the rudiments of palmar lines, the dermatoglyphic ridge count between the stable anatomical structures). The objective of the study was to look for the new diagnostic markers of the biological age. It included the identification of the palm prints obtained from 180 Caucasoid men and 120 women at the age varying from 16 to 80 years. The results of the mathematical and statistical analysis provided the basis for drawing up the list of 18 attributes of palm dermatoglyphics significantly (p<0.05) differing in the frequency of occurrence between the representatives of individual age groups. The methods are proposed allowing to use these findings for the expert evaluation of the age of unknown subjects.

  13. Obesity in young-adult Nigerians: variations in prevalence determined by anthropometry and bioelectrical impedance analysis, and the development of % body fat prediction equations

    PubMed Central

    2012-01-01

    Background Overweight/obesity is a growing global public health concern. The variations in the prevalence of overweight/obesity, defined by Body Mass Index (BMI), Waist Circumference (WC), Waist-to-Height Ratio (WHtR), Waist-to-Hip Ratio (WHpR) and Bioelectrical Impedance Analysis (BIA), were studied and a prediction equation for % body fat (%BF) developed. Methods A total of 1584 subjects (56.4% males) were recruited for the study. Data on age, gender, height, weight, hip circumference and WC were collected from the subjects using standard protocols. BMI, WHtR and WHpR were derived using standard equations. %BF was measured using a BIA device (Omron BF-400). Appropriate statistical tools were used for the data analysis. Results The prevalence of overweight/obesity in the population was 28.4% (36.3% for males; 22.6% for females) (BIA); 20.7% (17.5% for males; 24.8% for females) (BMI); 7.5% (1.3% for males; 16.1% for females) (WC); 2.9% (4.3% for males; 1.2% for females) (WHpR); and 15.4% (14.8% for males; 16.2% females) (WHtR). Taking BIA as the reference point, WC misclassified overweight/obesity the most for males (35%), while for the females, WHpR misclassified both disorders the most (21.4%). Correlation studies showed that only BMI correlated significantly, albeit weakly, with %BF among the males, whereas all the anthropometric measures, but WHpR correlated significantly with % body fat in females. Two prediction equations for %BF were generated, and %BF predicted with the two equations correlated significantly (P < 0.001) with that measured by BIA. Conclusion The prevalence of overweight/obesity in this population vary widely depending on the definition used. The developed prediction equations could be useful in resource-poor settings, but require validation. PMID:22818201

    Walking speed is a key vital sign in older people. Given the implications of slower gait speed, a large literature has identified health-related, behavioral, cognitive, and biological factors that moderate age-related decline in mobility. The present study aims to contribute to existing knowledge by examining whether subjective age, how old or young individuals experience themselves to be relative to their chronological age, contributes to walking speed. Participants were drawn from the 2008 and 2012 waves of the Health and Retirement Study (HRS, N = 2970) and the 2011 and 2013 waves of the National Health and Aging Trends Study (NHATS, N = 5423). In both the HRS and the NHATS, linear regression analysis revealed that a younger subjective age was associated with faster walking speed at baseline and with less decline over time, controlling for age, sex, education, and race. These associations were partly accounted for by depressive symptoms, disease burden, physical activity, cognition, body mass index, and smoking. Additional analysis revealed that feeling younger than one's age was associated with a reduced risk of walking slower than the frailty-related threshold of 0.6 m/s at follow-up in the HRS. The present study provides novel and consistent evidence across two large prospective studies for an association between the subjective experience of age and walking speed of older adults. Subjective age may help identify individuals at risk for mobility limitations in old age and may be a target for interventions designed to mitigate functional decline. PMID:26296609

    We investigated performance-derived measures of executive control, and their relationship with self- and informant reported executive functions in everyday life, in treatment-naive adults with newly diagnosed Attention Deficit Hyperactivity Disorder (ADHD; n = 36) and in healthy controls (n = 35). Sustained attentional control and response inhibition were examined with the Test of Variables of Attention (T.O.V.A.). Delayed responses, increased reaction time variability, and higher omission error rate to Go signals in ADHD patients relative to controls indicated fluctuating levels of attention in the patients. Furthermore, an increment in NoGo commission errors when Go stimuli increased relative to NoGo stimuli suggests reduced inhibition of task-irrelevant stimuli in conditions demanding frequent responding. The ADHD group reported significantly more cognitive and behavioral executive problems than the control group on the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A). There were overall not strong associations between task performance and ratings of everyday executive function. However, for the ADHD group, T.O.V.A. omission errors predicted self-reported difficulties on the Organization of Materials scale, and commission errors predicted informant reported difficulties on the same scale. Although ADHD patients endorsed more symptoms of depression and anxiety on the Achenbach System of Empirically Based Assessment (ASEBA) than controls, ASEBA scores were not significantly associated with T.O.V.A. performance scores. Altogether, the results indicate multifaceted alteration of attentional control in adult ADHD, and accompanying subjective difficulties with several aspects of executive function in everyday living. The relationships between the two sets of data were modest, indicating that the measures represent non-redundant features of adult ADHD. PMID:25545156

    Subjective cognitive complaints (SCCs) are increasingly a focus in studies of prodromal Alzheimer disease (AD) and risk for dementia. Little is known about the optimal approach to measure SCCs. We used item response theory (IRT) to examine characteristics of 24 SCC items in a sample of 3,495 older adults pooled from four community-based studies. We investigated the potential advantages of IRT scoring over conventional scoring, based on participants' item response patterns. Items most likely endorsed by individuals low in SCC severity relate to word retrieval and general subjective memory decline. Items likely endorsed only by individuals high in SCC severity relate to non-episodic memory changes, such as decline in comprehension, judgment and executive functions, praxis and procedural memory, and social behavior changes. IRT scoring of SCCs was associated with performance on objective cognitive test performance above and beyond total SCC scores, and was associated with objective cognitive test performance among participants endorsing only one SCC item. Thus, IRT scoring captures additional information beyond a simple sum of SCC symptoms. Modern psychometric approaches including IRT may be useful in developing 1) brief community screening questionnaires, and 2) more sensitive measures of very subtle subjective decline for use in prodromal AD research.

  1. Conceptions of traditional cosmological ideas among literate and nonliterate Nigerians

    Ogunniyi, M. B.

    This paper examines the nature of selected traditional cosmological concepts among literate and nonliterate Nigerians. An analysis of the data reveals that the subjects, irrespective of their level of education, class, sex, age, religion, tribe, or locality, hold in varying degrees certain traditional as well as scientific concepts about the natural phenomena. An exposure of some of the subjects to an history/philosophy of science course appears to enhance their preference for a scientific worldview vis a vis a traditional point-of-view. The implications of these findings for traditional societies deserve a closer consideration.

    We examined factors related to subjective quality of life (QoL) of adults with Autism Spectrum Disorder (ASD) aged 25 to 55 (n = 60), using the World Health Organization Quality of Life measure (WHOQOL-BREF). We used three different assessment methods: adult self-report, maternal proxy-report, and maternal report. Reliability analysis showed that adults with ASD rated their own QoL reliably. QoL scores derived from adult self-reports were more closely related to those from maternal proxy-report than from maternal report. Subjective factors such as perceived stress and having been bullied frequently were associated with QoL based on adult self-reports. In contrast, level of independence in daily activities and physical health were significant predictors of maternal reports of their son or daughter’s QoL. PMID:26707626

    Background An enhancement in recall of simple instructions is found when actions are performed in comparison to when they are verbally presented – the subject-performed task (SPT) effect. This enhancement has also been found with older adults. However, the reason why older adults, known to present a deficit in episodic memory, have a better performance for this type of information remains unclear. In this article, we explored this effect by comparing the performance on the SPT task with the performance on other tasks, in order to understand the underlying mechanisms that may explain this effect. Objective We hypothesized that both young and older adult groups should show higher recall in SPT compared with the verbal learning condition, and that the differences between age groups should be lower in the SPT condition. We aimed to explore the correlations between these tasks and known neuropsychological tests, and we also measured source memory for the encoding condition. Design A mixed design was used with 30 healthy older adults, comparing their performance with 30 healthy younger adults. Each participant was asked to perform 16 simple instructions (SPT condition) and to only read the other 16 instructions (Verbal condition – VT). The test phase included a free recall task. Participants were also tested with a set of neuropsychological measures (speed of processing, working memory and verbal episodic memory). Results The SPT effect was found for both age groups; but even for SPT materials, group differences in recall persisted. Source memory was found to be preserved for the two groups. Simple correlations suggested differences in correlates of SPT performance between the two groups. However, when controlling for age, the SPT and VT tasks correlate with each other, and a measure of episodic memory correlated moderately with both SPT and VT performance. Conclusions A strong effect of SPT was observed for all but one, which still displayed the expected aging

    Blood methanol concentrations were measured in 30 normal adult subjects administered aspartame, a dipeptide methyl ester. The doses studied included the 99th percentile of projected daily ingestion (34 mg/kg body weight) and three doses considered to be in the abuse range (100, 150, and 200 mg/kg body weight). Methanol concentrations were below the level of detection (0.4 mg/dl) in the blood of the 12 normal subjects who ingested aspartame at 34 mg/kg. They were significantly elevated (p less than or equal to 0 .001) after ingestion of each abuse dose, with the mean peak blood methanol concentrations and the areas under the blood methanol concentration-time curve increasing in proportion to dose. Mean (+/- SD) peak blood methanol concentrations were 1.27 +/- 0.48 mg/dl at the 100 mg/kg dose, 2.14 +/- 0.35 mg/dl at the 150 mg/kg dose, and 2.58 +/- 0.78 mg/dl at the 200 mg/kg dose. Blood methanol concentrations returned to predosing levels by 8 h after administration of the 100 mg/kg dose. Methanol was still detected in the blood 8 h after the subjects had ingested aspartame at 150 or 200 mg/kg. Blood formate analyses were carried out in the 6 subjects who ingested aspartame at 200 mg/kg, since recent studies indicate that the toxic effects of methanol are due to formate accumulation. No significant increase in blood formate concentrations over predosing concentrations was noted. No changes were noted in any of the blood chemistry profile parameters measured 24 h after aspartame ingestion, compared to values noted before administration. Similarly, no differences were noted in ophthalmologic examinations carried out before and after aspartame loading.

    Purpose of the Study: This research integrates successful aging and developmental adaptation models to empirically define the direct and indirect effects of 2 distal (i.e., education and past life experiences) and 5 proximal influences (i.e., physical functioning, cognitive functioning, physical health impairment, social resources, and perceived economic status) on subjective well-being. The proximal influences involved predictors outlined in most extant models of successful aging (e.g., Rowe & Kahn, 1998 [Rowe, J. W., & Kahn, R. L. (1998). Successful aging. New York: Pantheon Books.]). Our model extends such models by including distal impact as well as interactions between distal and proximal impacts. Design and Methods: Data were obtained from 234 centenarians and 72 octogenarians in the Georgia Centenarian Study. Structural equation modeling was conducted with Mplus 6.1. Results: Results showed significant direct effects of physical health impairment and social resources on positive aspects of subjective well-being among oldest-old adults. We also found significant indirect effects of cognitive functioning and education on positive affect among oldest-old adults. Social resources mediated the relationship between cognitive functioning and positive affect; and cognitive functioning and social resources mediated the relationship between education and positive affect. In addition, physical health impairment mediated the relationship between cognitive functioning and positive affect; and cognitive functioning and physical health impairment mediated the relationship between education and positive affect. Implications: Integrating 2 different models (i.e., successful aging and developmental adaptation) provided a comprehensive view of adaptation from a developmental perspective. PMID:25112594

    Functional imaging studies have revealed differential brain activation patterns in attention deficit hyperactivity disorder (ADHD) adult patients performing working memory (WM) tasks. The existence of alterations in WM-related cortical circuits during childhood may precede executive dysfunctions in this disorder in adults. To date, there is no study exploring the electrophysiological activation of WM-related neural networks in ADHD. To address this issue, we carried out an electroencephalographic (EEG) activation study associated with time-frequency (TF) analysis in 15 adults with ADHD and 15 controls performing two visual N-back WM tasks, as well as oddball detection and passive fixation tasks. Frontal transient (phasic) theta event-related synchronization (ERS, 0-500 msec) was significantly reduced in ADHD as compared to control subjects. Such reduction was equally present in a task-independent manner. In contrast, the power of the later sustained (∼500-1200 msec) theta ERS for all tasks was comparable in ADHD and control groups. In active WM tasks, ADHD patients displayed lower alpha event-related desynchronization (ERD, ∼200-900 msec) and higher subsequent alpha ERS (∼900-2400 msec) compared to controls. The time course of alpha ERD/ERS cycle was modified in ADHD patients compared to controls, suggesting that they are able to use late compensatory mechanisms in order to perform this WM task. These findings support the idea of an ADHD-related dysfunction of neural generators sub-serving attention directed to the incoming visual information. ADHD cases may successfully face WM needs depending on the preservation of sustained theta ERS and prolonged increase of alpha ERS at later post-stimulus time points. PMID:23518223

    Background: Emotion regulation strategies based on suppressing behavioral expressions of emotion have been considered maladaptive. However, this may not apply to suppressing the emotional experience (experiential suppression). The aim of this study was to define the effect of experiential suppression on subjective and physiological emotional responses. Methods: Healthy adults (N = 101) were characterized in terms of the temperament, personality, and hedonic capacity using the Tridimensional Personality Questionnaire, the Eysenck Personality Questionnaire, the Fawcett–Clark Pleasure Scale, and the State-Trait Anxiety Inventory. Participants were shown positive, negative, and neutral pictures from the International Affective Picture System under two conditions, passive viewing, and experiential suppression. During both conditions, subjective ratings of the intensity and duration of emotional responses and physiological measures of skin conductance (SC) and cardiac inter-beat interval (IBI) to each picture were recorded. Results: Negative pictures elicited the most intense physiological and emotional responses regardless of experimental condition. Ratings of emotional intensity were not affected by condition. In contrast, experiential suppression, compared to passive viewing, was associated with decreased duration of the emotional response, reduced maximum SC amplitude and longer IBIs independent of age, picture valence, personality traits, hedonic capacity, and anxiety. Conclusion: These findings demonstrate that experiential suppression may represent an adaptive emotion regulation mechanism associated with reduced arousal and cardiovascular activation.

    This cross-sectional study aims to investigate the differences in physical fitness and subjectively rated physical health of Vietnamese and German older adults in a community dwelling. The Vietnamese sample was a random sample of 96 community-dwelling individuals aged 60 to 80 years; 50 % were women. Education is 0 % less than 5 years, 23.95 % 5 to 9 years, 47.91 % 10 to 12 years, and 28.12 % more than 12 years. The German sample was a random sample of 159 community-dwelling persons aged 59 to 90 years; 79.8 % were women. Education is 1.25 % less than 5 years, 40.25 % 5 to 9 years, 38.84 % 10 to 12 years, and 21.38 % more than 12 years. Senior Fitness Test and Short Form-36 were used as outcome measures. The Vietnamese sample shows significantly higher performance levels in motor abilities, i.e., aerobic fitness, strength, and flexibility. The Vietnamese sample indicates a lower difference in performance levels between age groups than the German sample. No differences in subjectively rated physical health factors were found. The higher performance levels of the Vietnamese sample might reflect a more active lifestyle throughout the life span, especially in socially mediated domains like living arrangements or labor work. Lower performance levels in the studied age groups of the German sample might lead to higher risks of cardiovascular diseases and proneness of falls. A more active lifestyle after retirement could contribute to a healthier, more capable, and more independent individual and collective aging. Subjectively rated health stated is a culturally mitigated domain and therefore might be independent of actual physical fitness levels.

    Twenty apparently healthy and normal Nigerian female students, resident at the University of Ibadan campus, were studied for seven consecutive days to assess their food energy intake and energy expenditure during sedentary and physical activities. The mean age (years) of the group was 20.05 (SD 3.44, range 16-29), mean height (m) 1.62 (SD 0.07, range 1.47-1.74) and body-weight (kg) 51.28 (SD 3.21, range 46-58). The food intake of each subject was obtained by direct weighing, and the energy value determined using a ballistic bomb calorimeter. Daily activities were recorded and the energy cost of representative activities was determined by indirect calorimetry. Activities mainly involved sitting, mean (min/d) 354 (SD 84, range 253-475). Personal domestic activities took a mean of 162 (SD 73) min/d. Sleeping took a mean of 451 (SD 62) min/d. The mean energy intake of the group was 8480 (SD 1316) kJ/d or 167 (SD 30.6) kJ/kg body-weight per d. This value is lower than that recommended by the Food and Agriculture Organization/World Health Organization (FAO/WHO) (1973) as the energy requirement for adult women engaged in light activities (9205 kJ/d), but it is higher than the FAO/WHO/United Nations University (UNU) (1985) recommended value of 8326 kJ (1990 kcal)/d for a housewife in an affluent society. It is lower than the recommended intake of 9350 kJ/d for rural women in developing countries (FAO/WHO/UNU, 1985). The mean energy expenditure (kJ/d) of the female subjects was 6865 (SD 214, range 6519-7222). Mean energy expenditure was lower than mean energy intake. The energy intake and expenditure values indicated that the subjects participating in the present study were not physically very active. It is suggested, for health reasons, that they might undertake more physical activity. PMID:3593664

    The purpose of the present study was to investigate the coordination pattern and coordination variability (intra-subject and inter-subject) in children and adults during vertical countermovement jumps. Ten children (mean age: 11.5±1.8years) and ten adults (mean age: 26.1±4.9years) participated in the experiment. Lower body 3D-kinematics and kinetics from both legs were obtained during 9 vertical jumps of each subject. Coordination pattern and coordination variability of intra-limb and inter-limb coupling were established by modified vector coding and continuous relative phase. The adult group jumped higher and with less performance variability compared to the children. Group differences were mainly observed in the right-left foot coupling. The intra-subject coordination variability was higher in coupling of proximal segments in children compared to adults. No group differences were observed in inter-subject variability. Based on these results, it was concluded that the same movement solutions were available to both age groups, but the children were less able to consistently utilize the individually chosen coordination pattern. Thus, this ability appears to be developed through normal ontogenesis.

    Neonatal stress disrupts development of homeostatic systems. During adulthood, male rats subjected to neonatal maternal separation (NMS) are hypertensive and show a larger hypoxic ventilatory response (HVR), with greater respiratory instability during sleep. Neonatal stress also affects sex hormone secretion; hypoxia increases circulating testosterone of NMS (but not control) male rats. Given that these effects of NMS are not observed in females, we tested the hypothesis that testosterone elevation is necessary for the stress-related increase of the HVR in adult male rats. Pups subjected to NMS were placed in an incubator for 3 h per day from postnatal day 3 to 12. Control pups remained undisturbed. Rats were reared until adulthood, and the HVR was measured by plethysmography (fractional inspired O2 = 0.12, for 20 min). We used gonadectomy to evaluate the effects of reducing testosterone on the HVR. Gonadectomy had no effect on the HVR of control animals but reduced that of NMS animals below control levels. Immunohistochemistry was used to quantify androgen receptors in brainstem areas involved in the HVR. Androgen receptor expression was generally greater in NMS rats than in control rats; the most significant increase was noted in the caudal region of the nucleus tractus solitarii. We conclude that the abnormal regulation of testosterone is important in stress-related augmentation of the HVR. The greater number of androgen receptors within the brainstem may explain why NMS rats are more sensitive to testosterone withdrawal. Based on the similarities of the cardiorespiratory phenotype of NMS rats and patients suffering from sleep-disordered breathing, these results provide new insight into its pathophysiology, especially sex-based differences in its prevalence.

    Eltrombopag is an orally bioavailable thrombopoietin receptor agonist that is approved for the treatment of chronic idiopathic thrombocytopenic purpura. It is being developed for other medical disorders that are associated with thrombocytopenia. Patients with human immunodeficiency virus (HIV) may suffer from thrombocytopenia as a result of their HIV disease or coinfection with hepatitis C virus (HCV). HIV medications, particularly ritonavir (RTV)-boosted HIV protease inhibitors, are involved in many drug interactions. This study evaluated the potential drug-drug interaction between eltrombopag and lopinavir (LPV)/RTV. Forty healthy adult subjects enrolled in this open-label, three-period, single-sequence crossover study received a single 100-mg dose of eltrombopag (period 1), LPV/RTV at 400/100 mg twice daily (BID) for 14 days (period 2), and LPV/RTV at 400/100 mg BID (2 doses) with a single 100-mg dose of eltrombopag administered with the morning LPV/RTV dose (period 3). There was a 3-day washout between periods 1 and 2 and no washout between periods 2 and 3. Serial pharmacokinetic samples were collected during 72 h in periods 1 and 3 and during 12 h in period 2. The coadministration of 400/100 mg LPV/RTV BID with a single dose of 100 mg eltrombopag decreased the plasma eltrombopag area under the plasma concentration-time curve from time zero extrapolated to infinity (AUC(0-∞)) by 17%, on average, with no change in plasma LPV/RTV exposure. Adverse events (AEs) reported in period 2 were consistent with known LPV/RTV AEs, such as diarrhea, abdominal pain, nausea, vomiting, rash, and fatigue. No subjects withdrew due to AEs, and no serious AEs were reported. These study results suggest that platelet counts should be monitored and the eltrombopag dose adjusted accordingly if LPV/RTV therapy is initiated or discontinued. PMID:22391553

    Argentina is among the Ibero-American countries with the greatest old age population, and is going through a process of advanced demographic transition. Elderly adults have long been considered a vulnerable group in need of care. The purpose of this work was to problematize the conceptions underlying the care given to the elderly in nursing homes, and the possible slides this involves from a human rights stance. An approach to this problem was built up by resorting to secondary documentary sources and interviews with key informants located in institutions for the elderly in the Province of Cordoba. This approach revealed a predominantly asylum-oriented conception centered on caring for others as objects, and a noticeable lack of consideration for the elderly as legal subjects, visible in numerous serious infringements of human rights, mostly silenced and rendered invisible. It seems that to overcome these situations it will be necessary not merely to review legal loopholes and current programs but also to reconsider the place given to the elderly in society. Regardless of their age and other social differences, the elderly require the same opportunities to claim full respect and exercise their human rights and fundamental freedoms. PMID:26650412

    Pyronaridine-artesunate is a newly introduced artemisinin-based combination treatment which may be deployed together with primaquine. A single-dose, randomized, three-sequence crossover study was conducted in healthy Thai volunteers to characterize potential pharmacokinetic interactions between these drugs. Seventeen healthy adults received a single oral dose of primaquine alone (30 mg base) and were then randomized to receive pyronaridine-artesunate alone (540−180 mg) or pyronaridine-artesunate plus primaquine in combination, with intervening washout periods between all treatments. The pharmacokinetic properties of primaquine, its metabolite carboxyprimaquine, artesunate, its metabolite dihydroartemisinin, and pyronaridine were assessed in 15 subjects using a noncompartmental approach followed by a bioequivalence evaluation. All drugs were well tolerated. The single oral dose of primaquine did not result in any clinically relevant pharmacokinetic alterations to pyronaridine, artesunate, or dihydroartemisinin exposures. There were significantly higher primaquine maximum plasma drug concentrations (geometric mean ratio, 30%; 90% confidence interval [CI], 17% to 46%) and total exposures (15%; 6.4% to 24%) during coadministration with pyronaridine-artesunate than when primaquine was given alone. Pyronaridine, like chloroquine and piperaquine, increases plasma primaquine concentrations. (This study has been registered at ClinicalTrials.gov under registration no. NCT01552330.) PMID:25385096

    Background Little prospectively collected data are available comparing the dietary intake of urea cycle disorder (UCD) patients to UCD treatment guidelines or to healthy individuals. Objective To examine the protein and calorie intakes of UCD subjects who participated in clinical trials of glycerol phenylbutyrate (GPB) and compare these data to published UCD dietary guidelines and nutritional surveys. Design Dietary data were recorded for 45 adult and 49 pediatric UCD subjects in metabolic control during participation in clinical trials of GPB. Protein and calorie intakes were compared to UCD treatment guidelines, average nutrient intakes of a healthy US population based on the National Health and Nutrition Examination Survey (NHANES) and Recommended Daily Allowances (RDA). Results In adults, mean protein intake was higher than UCD recommendations but lower than RDA and NHANES values, while calorie intake was lower than UCD recommendations, RDA and NHANES. In pediatric subjects, prescribed protein intake was higher than UCD guidelines, similar to RDA, and lower than NHANES data for all age groups, while calorie intake was at the lower end of the recommended UCD range and close to RDA and NHANES data. In pediatric subjects height, weight, and body mass index (BMI) Z-scores were within normal range (− 2 to 2). Conclusions Pediatric patients treated with phenylbutyrate derivatives exhibited normal height and weight. Protein and calorie intakes in adult and pediatric UCD subjects differed from UCD dietary guidelines, suggesting that these guidelines may need to be reconsidered. PMID:27014577

    Some healthy older adults show departures from standard decision-making patterns exhibited by younger adults. We asked if such departures are uniform or if heterogeneous aging processes can designate which older adults show differing decision patterns. Thirty-three healthy older adults with varying decision-making patterns on a complex decision task (the Iowa Gambling Task) completed an intertemporal choice task while undergoing functional magnetic resonance imaging. We examined whether value representation in the canonical valuation network differed across older adults based on complex decision-making ability. Older adults with advantageous decision patterns showed increased activity in the valuation network, including the ventromedial prefrontal cortex (VMPFC) and striatum. In contrast, older adults with disadvantageous decision patterns showed reduced or absent activation in the VMPFC and striatum, and these older adults also showed greater blood oxygen level dependent signal temporal variability in the striatum. Our results suggest that a reduced representation of value in the brain, possibly driven by increased neural noise, relates to suboptimal decision-making in a subset of older adults, which could translate to poor decision-making in many aspects of life, including finance, health and long-term care. Understanding the connection between suboptimal decision-making and neural value signals is a step toward mitigating age-related decision-making impairments.

    The present study investigated the relationship between personality and Subjective Well-Being in a sample of 135 Salvadorian adolescents and young adults (age mean = 21.88 sd. = 4.70). Personality was assessed through self-reports using the Temperament and Character Inventory-Revised. Subjective Well-Being was also self-reported using the Positive Affect Negative Affect Schedule and the Satisfaction With Life Scale. Structural equation modeling was used to determine relationships between personality and Subjective Well-Being. Regarding temperament dimensions, Harm Avoidance was positively associated to negative affect and negatively associated to positive affect, while Persistence was positively associated to positive affect. Regarding character dimensions, only Self-directedness was related to Subjective Well-Being: positively related to life satisfaction and positive affect. The results presented here mirror findings using the temperament and character model of personality among European and North American adolescents.

    2015-01-01

    Few studies have compared the phenomenological properties of younger and older adults' memories for emotional events. Some studies suggest that younger adults remember negative information more vividly than positive information whereas other studies suggest that positive emotion yields phenomenologically richer memories than negative emotion for both younger and older adults. One problem with previous studies is a tendency to treat emotion as a dichotomous variable. In contrast, emotional richness demands inclusion of assessments beyond just a positive and negative dimension (e.g., assessing specific emotions like anger, fear and happiness). The present study investigated different properties of autobiographical remembering as a function of discrete emotions and age. Thirty-two younger and thirty-one older adults participated by recalling recent and remote memories associated with six emotional categories and completed the Memory Characteristics Questionnaire for each. Results demonstrated that older adults' angry memories received lower ratings on some phenomenological properties than other emotional memories whereas younger adults' angry memories did not show this same pattern. These results are discussed within the context of socioemotional selectivity theory. PMID:25029295

    Background Tobacco use over the life-course threatens to increase disease burden in older adulthood, including lower income countries like Ghana. This paper describes demographic, socioeconomic, health risks and life satisfaction indices related to tobacco use among older adults in Ghana. Methods This work was based on the World Health Organization’s multi-country Study on global AGEing and adult health (SAGE), conducted in six countries including Ghana. Wave one of SAGE in Ghana was conducted in 2007-2008 as collaboration between WHO and the University of Ghana Medical School through the Department of Community Health. A nationally representative sample of 4305 older adults aged 50 years and above were interviewed. Associations between tobacco consumption and sociodemographic, socioeconomic, health risk and life satisfaction were evaluated using chi-square and odds ratio (OR). Logistic regression analyses, adjusted for age, sex and other variables, were conducted to determine predictors of tobacco consumption in older persons. Results Overall prevalence of current daily smokers among older adults in Ghana was 7.6%. Tobacco use (i.e. ever used tobacco) was associated with older males, (AOR = 1.10, CI 1.05-1.15), older adults residing in rural locations (AOR = 1.37, CI 1.083-1.724), and older adults who used alcohol (AOR = 1.13, CI 0.230-2.418). Tobacco use was also associated (although not statistically significant per p-values) with increased self-reporting of angina, arthritis, asthma, chronic lung disease, depression, diabetes, hypertension, and stroke. Older adults who used tobacco and with increased health risks, tended to be without health insurance (AOR = 1.41, CI 1.111-1.787). Satisfaction with life and daily living was much lower for those who use tobacco. Regional differences existed in tobacco use; the three northern regions (Upper East, Northern and Upper West) had higher proportions of tobacco use among older adults in the country

    Ingestion of aspartame-sweetened beverages has been reported to increase subjective measures of appetite. This study examined the effects of familiar carbonated soft drinks sweetened with aspartame on subjective hunger, energy intake and macronutrient selection at a lunch-time meal. Subjects were 20 normal weight young adult males, classified as either restrained or nonrestrained eaters. Four treatments of carbonated beverages included 280 ml of mineral water, one can of a soft drink (280 ml) consumed in either 2 or 10 minutes, or two cans of a soft drink (560 ml) consumed in 10 minutes, administered at 11:00 a.m. Subjective hunger and food appeal were measured from 9:30 a.m. to 12:30 p.m., and food intake data were obtained from a buffet lunch given at 12:00 noon. There were no treatment effects on energy intake, macronutrient selection or food choice at the lunch-time meal, or food appeal, though restrained eaters consumed more than nonrestrained eaters in all four treatment conditions. Consumption of two soft drinks (560 ml, 320 mg aspartame) significantly reduced subjective hunger from 11:05 a.m. to 11:30 a.m. compared to one soft drink (280 ml, 160 mg aspartame) or 280 ml of mineral water. Thus ingestion of soft drinks containing aspartame did not increase short-term subjective hunger or food intake.

    The pharmacokinetic profile of ceftaroline has not been well characterized in obese adults. The purpose of this study was to evaluate the pharmacokinetics of ceftaroline in 32 healthy adult volunteers aged 18 to 50 years in the normal, overweight, and obese body size ranges. Subjects were evenly assigned to 1 of 4 groups based on their body mass index (BMI) and total body weight (TBW) (ranges, 22.1 to 63.5 kg/m2 and 50.1 to 179.5 kg, respectively). Subjects in the lower-TBW groups were matched by age, sex, race/ethnicity, and serum creatinine to the upper-BMI groups. Serial plasma and urine samples were collected over 12 h after the start of the infusion, and the concentrations of ceftaroline fosamil (prodrug), ceftaroline, and ceftaroline M-1 (inactive metabolite) were assayed. Noncompartmental and population pharmacokinetic analyses were used to evaluate the data. The mean plasma ceftaroline maximum concentration and area under the curve were ca. 30% lower in subjects with a BMI of ≥40 kg/m2 compared to those <30 kg/m2. A five-compartment pharmacokinetic model with zero-order infusion and first-order elimination optimally described the plasma concentration-time profiles of the prodrug and ceftaroline. Estimated creatinine clearance (eCLCR) and TBW best explained ceftaroline clearance and volume of distribution, respectively. Although lower ceftaroline plasma concentrations were observed in obese subjects, Monte Carlo simulations suggest the probability of target attainment is ≥90% when the MIC is ≤1 μg/ml irrespective of TBW or eCLCR. No dosage adjustment for ceftaroline appears to be necessary based on TBW alone in adults with comparable eCLCR. Confirmation of these findings in infected obese patients is necessary to validate these findings in healthy volunteers. (This study has been registered at ClinicalTrials.gov under registration no.

    The incidence of cholesteatoma among Nigerians is not well documented, as is the outcome of surgical treatment. A descriptive analysis of prospectively collected data of cases of cholesteatoma managed with tympanomastoidectomy at National Hospital Abuja between September 2005 and April 2012 is presented. Cases were analyzed for age, sex, type of cholesteatoma, intra-operative findings, and post-operative outcome after 6 months of follow up. A total of 28 ears from 25 cases of cholesteatoma had tympanomastoidectomy. Age range was 6-73 years (mean = 34.4, SD = 18.67). There were 13 females and 12 males. Primary acquired cholesteatoma was seen in 18 cases (20 ears), secondary acquired in 5 cases (six ears), and external auditory canal cholesteatoma was seen in 2 cases (two ears). The sites involved in middle ear cholesteatoma was attic, sinus and mesotympanum pars tensa (16/26), attic, sinus, antrum and mastoid cavity (5/26), attic, sinus, mesotympanum and mastoid antrum (4/26), and attic only (3/26).21/25 of cases (24 ears) managed had single stage intact canal wall (ICW) tympanomastoidectomy, while 4/25 (4 ears) had two-stage surgery with canal wall down tympanomastoidectomy in two of these, and revision surgery done within 12 months of first surgeries. 2/25 cases (in the two stage revision group) had postoperative persistent mastoid cutaneous fistula and were treated with post-auricular advancement flap. The commonest cholesteatoma type seen at National Hospital Abuja, Nigeria was primary acquired type, and involved the attic, sinus and mesotympanum pars tensa mainly, and most can be managed by single stage tympanomastoidectomy.

  4. The Influence of Executive Functioning on Facial and Subjective Pain Responses in Older Adults

    PubMed Central

    2016-01-01

    Cognitive decline is known to reduce reliability of subjective pain reports. Although facial expressions of pain are generally considered to be less affected by this decline, empirical support for this assumption is sparse. The present study therefore examined how cognitive functioning relates to facial expressions of pain and whether cognition acts as a moderator between nociceptive intensity and facial reactivity. Facial and subjective responses of 51 elderly participants to mechanical stimulation at three intensities levels (50 kPa, 200 kPa, and 400 kPa) were assessed. Moreover, participants completed a neuropsychological examination of executive functioning (planning, cognitive inhibition, and working memory), episodic memory, and psychomotor speed. The results showed that executive functioning has a unique relationship with facial reactivity at low pain intensity levels (200 kPa). Moreover, cognitive inhibition (but not other executive functions) moderated the effect of pressure intensity on facial pain expressions, suggesting that the relationship between pressure intensity and facial reactivity was less pronounced in participants with high levels of cognitive inhibition. A similar interaction effect was found for cognitive inhibition and subjective pain report. Consequently, caution is needed when interpreting facial (as well as subjective) pain responses in individuals with a high level of cognitive inhibition. PMID:27274618

    2004-01-01

    Background We sought to evaluate the hypothesis that the high incidence of cutaneous melanoma in white persons in central Alabama is associated with a predominance of Irish and Scots descent. Methods Frequencies of country of ancestry reports were tabulated. The reports were also converted to scores that reflect proportional countries of ancestry in individuals. Using the scores, we computed aggregate country of ancestry indices as estimates of group ancestry composition. HLA-DRB1*04 allele frequencies and relationships to countries of ancestry were compared in probands and controls. Results were compared to those of European populations with HLA-DRB1*04 frequencies. Results Ninety evaluable adult white cutaneous melanoma probands and 324 adult white controls reported countries of ancestry of their grandparents. The respective frequencies of Ireland, and Scotland and "British Isles" reported countries of ancestry were significantly greater in probands than in controls. The respective frequencies of Wales, France, Italy and Poland were significantly greater in controls. 16.7% of melanoma probands and 23.8% of controls reported "Native American" ancestry; the corresponding "Native American" country of ancestry index was not significantly different in probands and controls. The frequency of HLA-DRB1*04 was significantly greater in probands, but was not significantly associated with individual or aggregate countries of ancestry. The frequency of DRB1*04 observed in Alabama was compared to DRB1*04 frequencies reported from England, Wales, Ireland, Orkney Island, France, Germany, and Australia. Conclusion White adults with cutaneous melanoma in central Alabama have a predominance of Irish, Scots, and "British Isles" ancestry and HLA-DRB1*04 that likely contributes to their high incidence of cutaneous melanoma.

    Despite the relevance of prospective memory to everyday functioning and the ability to live independently, prospective memory tasks are rarely incorporated into clinical evaluations of older adults. We investigated the validity and clinical utility of a recently developed measure, the Royal Prince Alfred Prospective Memory Test (RPA-ProMem), in a demographically diverse, non-demented, community-dwelling sample of 257 older adults (mean age = 80.78 years, 67.7% female) with amnestic mild cognitive impairment (aMCI, n = 18), non-amestic mild cognitive impairment (naMCI, n = 38), subjective cognitive decline (SCD, n = 83) despite intact performance on traditional episodic memory tests, and healthy controls (HC, n = 118). Those with aMCI and naMCI performed significantly worse than controls on the RPA-ProMem and its subtasks (time-based, event-based, short-term, long-term). Also, those with SCD scored significantly lower than controls on long-term, more naturalistic subtasks. Additional results supported the validity and inter-rater reliability of the RPA-ProMem and demonstrated a relation between test scores and informant reports of real-world functioning. The RPA-ProMem may help detect subtle cognitive changes manifested by individuals in the earliest stages of dementia, which may be difficult to capture with traditional episodic memory tests. Also, assessment of prospective memory can help guide the development of cognitive interventions for older adults at risk for dementia. PMID:24875614

    Over 500 million people interact daily with Facebook. Yet, whether Facebook use influences subjective well-being over time is unknown. We addressed this issue using experience-sampling, the most reliable method for measuring in-vivo behavior and psychological experience. We text-messaged people five times per day for two-weeks to examine how Facebook use influences the two components of subjective well-being: how people feel moment-to-moment and how satisfied they are with their lives. Our results indicate that Facebook use predicts negative shifts on both of these variables over time. The more people used Facebook at one time point, the worse they felt the next time we text-messaged them; the more they used Facebook over two-weeks, the more their life satisfaction levels declined over time. Interacting with other people "directly" did not predict these negative outcomes. They were also not moderated by the size of people's Facebook networks, their perceived supportiveness, motivation for using Facebook, gender, loneliness, self-esteem, or depression. On the surface, Facebook provides an invaluable resource for fulfilling the basic human need for social connection. Rather than enhancing well-being, however, these findings suggest that Facebook may undermine it.

The more people used Facebook at one time point, the worse they felt the next time we text-messaged them; the more they used Facebook over two-weeks, the more their life satisfaction levels declined over time. Interacting with other people “directly” did not predict these negative outcomes. They were also not moderated by the size of people's Facebook networks, their perceived supportiveness, motivation for using Facebook, gender, loneliness, self-esteem, or depression. On the surface, Facebook provides an invaluable resource for fulfilling the basic human need for social connection. Rather than enhancing well-being, however, these findings suggest that Facebook may undermine it. PMID:23967061

    Adequate central nervous system noradrenergic activity enhances cognition, but excessive noradrenergic activity may have adverse effects on cognition. Previous studies have also demonstrated that noradrenergic activity is higher in older than younger adults. We aimed to determine relationships between cerebrospinal fluid (CSF) norepinephrine (NE) concentration and cognitive performance by using data from a CSF bank that includes samples from 258 cognitively normal participants aged 21-100 years. After adjusting for age, gender, education, and ethnicity, higher CSF NE levels (units of 100 pg/mL) are associated with poorer performance on tests of attention, processing speed, and executive function (Trail Making A: regression coefficient 1.5, standard error [SE] 0.77, p = 0.046; Trail Making B: regression coefficient 5.0, SE 2.2, p = 0.024; Stroop Word-Color Interference task: regression coefficient 6.1, SE 2.0, p = 0.003). Findings are consistent with the earlier literature relating excess noradrenergic activity with cognitive impairment.

    Subjective health status was assessed in relation to overweight by administering a list of 51 health complaints to adult men and women who were either chronically overweight as defined by Body Mass Index (BMI) or not overweight, in a continuous morbidity registration in four general practices during the period 1967-83. Responses were received from 455 men (182 overweight) and 790 women (386 overweight), ages 26-66 years. Response rate (71 per cent) and age distribution (mean age 48) were similar in overweight and non-overweight groups of both sexes. BMI was correlated with the total number of complaints in women (r = 0.15) but not in men (r = 0.07). Multiple regression analysis revealed, however, that age was an effect modifier in this relation, there being a negative association between BMI and subjective health in younger men and a positive association in older men, whereas in women the association between BMI and subjective health was much more pronounced at younger ages than at older ages. In addition, current smoking habits and social class (in men and women) and reported slimming behavior (in women) had an independent relation to the total number of health complaints. BMI was also related to specific complaints and groups of complaints, particularly in women. PMID:3777287

    INTRODUCTION. Many young people today display memory complaints that are not linked to their real cognitive performance. A number of studies have sought to identify the factors involved in this problem, such as anxious-depressive symptoms, the variables of anxiety traditionally being measured as somatic or cognitive manifestations with an activation that is unspecific or not linked to any particular stimulus. AIMS. To perform an exploratory analysis to determine the role played by symptoms of depression and of various subtypes of specific and unspecific anxiety in memory complaints in young adults. PATIENTS AND METHODS. The sample used in this study was made of 193 university students, 71% of whom were females, with a mean age of 22.22 ± 3.67 years. The variable 'Memory complaints' was measured with the Memory Failures Questionnaire, and the Brief Symptom Check List was used to measure the variables 'Depression', 'Social anxiety', 'Obsessive-compulsive anxiety', 'Agoraphobic anxiety', 'Somatisation' and 'Insomnia'. RESULTS. The variables of specific anxiety show a greater correlation with memory complaints than unspecific anxiety. Multiple regression analysis explained 34.9% of the variance of memory complaints, although the only variable that made a significant contribution was 'Social anxiety', which alone explains 34.4%. CONCLUSIONS. A distinct influence between the different types of anxiety and memory complaints has been observed. The findings obtained are a novelty in this area of knowledge by pointing to a greater relevance of the variables of specific anxiety in comparison to unspecific anxiety in explaining memory complaints and the need to take a personalised approach.

    The 20-item Computer Anxiety Scale was administered to a Nigerian sample of 162 undergraduates in education (53 men and 109 women). Analysis indicated that the construct of computer anxiety appears to be invariant with respect to sex, year of study, or group (science/nonscience). In addition, a high prevalence of computer anxiety was observed as about two-thirds of the participants had computer anxiety scores exceeding 60 with a mean score of 65.3 (SD= 16.6).

The purpose of the present study was the search for the new biological markers of biological age. The material for the study consisted of the palm prints obtained from 180 men and 120 women of the Caucasoid stock at the age from 16 to 80 years. The use of the descriptive statistics methods yielded the basic statistical characteristics of the traits being investigated and revealed the limits of their variability in the groups of men and women belonging to the age groups from 16 to 29 and from 30 to 80 years. The method of threshold values made it possible to identify 13 attributes the excess of which allows, with the probability of no less than 0.95, to perform diagnostics of the age group of an unknown subject.

    2014-01-01

    Accelerometry-based gait analysis is widely recognised as a promising tool in healthcare and clinical settings since it is unobtrusive, inexpensive and capable of providing insightful information on human gait characteristics. In order to expand the application of this technology in daily environments, it is desirable to develop reliable gait measures and their extraction methods from the acceleration signal that can differentiate between normal and atypical gait. Important examples of such measures are gait cycle and gait-induced acceleration magnitude, which are known to be closely related to each other depending on each individual's physical condition. In this study, we derive a model equation with two parameters which captures the essential relationships between gait cycle and gait acceleration based on experiments and physical modelling. We also introduce as a new gait parameter a set of indexes to evaluate the synchronisation behaviour of gait timing. The function and utility of the proposed parameters are examined in 11 healthy subjects during walking under various selected conditions.

    1995-11-01

    The factor validity of the new Aberrant Behavior Checklist-Community (ABC-C) was determined with 1,040 group home residents. Exploratory factor analysis indicated that the factor structure derived from the original ABC appears to be valid for the ABC-C when used with this population. Coefficients of congruence showed a high level of concordance with the original factor structure, and internal consistency continued to be high for each of the five subscales. Analyses for the effects of age, gender, and level of mental retardation indicated that some correction is appropriate for each of these variables when scoring the ABC-C. Further analyses explored the effects of subjects variables such as visual and auditory handicaps and the presence of epilepsy or Down syndrome. Psychotropic medication use was often associated with subscale score differences. The original ABC factor structure appears valid for scoring the ABC-C with community-based adults, at least those living in group homes.

    The introduction, in the late 70s, of the first digital spectrograph (DSP Sonograph) by Kay Elemetrics has improved the possibilities of spectroacoustic voice analysis in the clinical field. Thanks to the marketing, in 1993, of the Multi Dimensional Voice Program (MDVP) advanced system, it is now possible to analyse 33 quantitative voice parameters which, in turn, allow evaluation of fundamental frequency, amplitude and spectral energy balance and the presence of any sonority gap and diplophony. Despite its potentials, the above-mentioned system is not widely used yet, partly on account of the lack of a standard procedure. Indeed, there are still only a few case reports in the literature taking into consideration prescriptive aspects related both to procedure and analysis. This study aims to provide the results of amplitude perturbation parameter analysis in euphonic adult patients. In our opinion, these are the most significant parameters in determining the severity of a phonation disorder. The study has been carried out on 35 patients (24 female, 11 male, mean age 31.6 years, range 19-59). The voice signal has been recorded using a 4300 B Kay Computer Speech Lab (CSL) supported by a personal computer including a SM48 Shure-Prolog microphone located at a distance of 15 cm and angled at 45 degrees. Input microphone saturation has been adjusted to 6/9 of the CH1 channel. The voice sample consisted in a held /a/ and the analysis has been carried out on the central 3 seconds of the recording. The analysis has been carried out using a 5105 MDVP software version 2.3 and the signal digitalised at a 50 kHz sample rate. In order for the sample to be as free from intensity or frequency changes as possible, each patient underwent a training session (including at least 3 phonation tests) before the recording. The study included only emissions between 55 and 65 dB and with spectrum stability. Environmental noise has constantly been monitored and maintained below 30 dB. Data

    Introduction Despite the well-known maxim "publish or perish" among academicians, productivity remains low in Nigeria. There are barriers to academic writing which must be identified and addressed. Even after addressing those barriers, authors are faced with another dilemma-where to publish. It was the concern of the authors to evaluate perceived barriers to academic writing and the determinants of journal choice among Nigerian academics. They also attempted to evaluate the determinants of journal choice and perceived barriers to academic writing among Nigerian academicians. Respondents were academicians used in the context of this study to mean anyone involved in academic writing. Such persons must have written and published at least one paper in a peer-reviewed journal in the preceding year to be included in the survey. An online-based self-administered questionnaire. Methods An online structured and self-administered questionnaire-based cross sectional survey of Nigerian medical academicians was conducted over a period of one year using a Google-powered questionnaire. The questionnaire assessed the determinants of journal choice, perceived barriers to publications, number of publications in the preceding year as a measure of academic productivity and the highest publication fee authors were willing to pay. Results Of the over 500 email request sent, a total of 200 academicians responded (response rate of 40%). The male and female distribution was 120 and 80 respectively. The highest number of respondents were lecturer 1 and senior lecturers (or junior faculty) (69.5%) however the senior faculty had the higher number of publications in the preceding year. Indexing (35.5%) was the most important determinant of journal choice whilst ease of submission (2.1%) was the least. Unfriendly environment (46%) was the most perceived barrier to publication. Though, majority (88.5%) of the respondents were willing to pay up $300 as publication fees, twice as many junior

    Background Comparative cardiovascular responses to treadmill and bicycle ergometer (bike) exercise tests in hypertensive Nigerians are not known. This study compared cardiovascular responses to the two modes of exercise testing in hypertensives using maximal exercise protocols. Methods One hundred and ten male subjects with mild-to-moderate hypertension underwent maximal treadmill and bike test one after the other at a single visit in a simple random manner. Paired-sampled t-test was used to compare responses to both exercise tests while chi-squared test was used to compare categorical variables. Results The maximal heart rate (P<0.001), peak systolic blood pressure (P=0.02), rate pressure product (P<0.001), peak oxygen uptake (P<0.001), and exercise capacity (P<0.001) in metabolic equivalents were signifcantly higher on the treadmill than on the bike. Conclusion Higher cardiovascular responses on treadmill in Nigerian male hypertensives in this study, similar to findings in non-hypertensives and non-Nigerians in earlier studies, suggest that treadmill may be of better diagnostic utility in our population.

    Juvenile dermatomyositis is an autoimmune connective tissue disease occurring in children less than 16 years old. It is part of a heterogeneous group of muscle diseases called idiopathic Iiflammatory myopathies. It had previously been reported in black Africans resident in UK. However, there is no documented case reported from Africa. The index sign of heliotrope rashes is often difficult to visualise in the black skin. An 11-year-old Nigerian girl presenting with clinical, laboratory and histopathological features of juvenile dermatomyositis is presented here. It is hoped that this case will heighten the index of suspicion of this condition among medical practitioners in Africa. PMID:24706700

    Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. The Subjective Cognitive Decline Initiative (SCD-I) Working Group is an international consortium established to develop a conceptual framework and research criteria for SCD (Jessen et al., 2014, Alzheimers Dement 10, 844-852). In the current study we systematically compared cognitive self-report items used by 19 SCD-I Working Group studies, representing 8 countries and 5 languages. We identified 34 self-report measures comprising 640 cognitive self-report items. There was little overlap among measures- approximately 75% of measures were used by only one study. Wide variation existed in response options and item content. Items pertaining to the memory domain predominated, accounting for about 60% of items surveyed, followed by executive function and attention, with 16% and 11% of the items, respectively. Items relating to memory for the names of people and the placement of common objects were represented on the greatest percentage of measures (56% each). Working group members reported that instrument selection decisions were often based on practical considerations beyond the study of SCD specifically, such as availability and brevity of measures. Results document the heterogeneity of approaches across studies to the emerging construct of SCD. We offer preliminary recommendations for instrument selection and future research directions including identifying items and measure formats associated with important clinical outcomes.

    Background The MacArthur Scale of Subjective Social Status intend to measure the subjective social status using a numbered stepladder image. This study investigated the reliability of the MacArthur scale in a subsample of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Method Three scales were employed using different references: 1) the overall socioeconomic position; 2) the socioeconomic situation of the participant’s closer community; 3) the workplace as a whole. A total of 245 of the ELSA participants from six states were involved. They were interviewed twice by the same person within an interval of seven to fourteen days. The reliability of the scale was assessed with weighted Kappa statistics and intraclass correlation coefficient (ICC), with their respective 95% confidence interval (CI). Results Kappa values were 0.62(0.58 to 0.64) for the society ladder; 0.58(0.56 to 0.61) for the community-related ladder; and 0.67(0.66 to 0.72) for the work-related ladder. The ICC ranged from 0.75 for the work ladder to 0.64 for the community ladder. These values differed slightly according to the participants’ age, sex and education category. Conclusion The three ladders showed good stability in the test-retest, except the community ladder that showed moderate stability. Because the social structure in Brazil is rapidly changing, future qualitative and longitudinal studies are needed to confirm and understand the construct underlying the MacArthur Scale in the country.

    Inexpensive, easy-to-use, and highly sensitive diagnostic tests are currently unavailable for typhoid fever. To identify candidate serodiagnostic markers, we have probed microarrays displaying the full Salmonella enterica serovar Typhi (S. Typhi) proteome of 4,352 different proteins + lipopolysaccharides (LPSs), with sera from Nigerian pediatric typhoid and other febrile cases, Nigerian healthy controls, and healthy U.S. adults. Nigerian antibody profiles were broad (∼500 seropositive antigens) and mainly low level, with a small number of stronger "hits," whereas the profile in U.S. adults was < 1/5 as broad, consistent with endemic exposure in Nigeria. Nigerian profiles were largely unaffected by clinical diagnosis, although the response against t1477 (hemolysin E) consistently emerged as stronger in typhoid cases. The response to LPS was also a strong discriminator of healthy controls and typhoid, although LPS did not discriminate between typhoid and nontyphoidal Salmonella (NTS) disease. As a first step toward the development of a point-of-care diagnostic, t1477 and LPS were evaluated on immunostrips. Both provided good discrimination between healthy controls and typhoid/NTS disease. Such a test could provide a useful screen for salmonellosis (typhoid and NTS disease) in suspected pediatric cases that present with undefined febrile disease. PMID:27215295

    This paper presents the result of a research which investigated the influence of the subjective factors 'adult attachment style' and 'perception of social support' in the occurrence of post traumatic stress disorders (PTSD) in a population of 544 subjects working for a security company and the Belgian Red Cross. The analysis of the results suggests that 'adult attachment style' and 'perception of social support' moderate between a critical incident and the occurrence of a PTSD. In other words, these independent variables differentiate between individuals who are more, and who are less prone, to suffer from a PTSD after having experienced a critical incident. The results of this research shed light on subjective risk factors related to PTSD. The findings can also suggest guidelines for the treatment of individuals suffering from a PTSD.

    INTRODUCTION. Pain intensity and oral health practices among patients with toothache, a major dental public health problem is necessary information for the formulation of preventive and interventional oral health policies. OBJECTIVE. To assess the pain intensity and oral health practices among dental patients attending a Nigerian secondary healthcare setting with toothache. MATERIALS AND METHODS. This study was a prospective study of adult patients attending the dental clinic of Rasheed Shekoni Specialist Hospital, Dutse, Jigawa State, Nigeria. Interviewer-administered questionnaire which elicited information include demography, pain intensity using visual analogue, tooth brushing behaviour and previous dental treatment was the tool of data collection. RESULTS. The majority of the respondents were males and young adults. More than half (60.5%) of the respondents reported pain of moderate to severe intensity and 42.6% have engaged in self medication for the toothache. More than one-third (34.2%) had experienced the pain for ≥ four weeks and the major factor that prompted the decision to visit dentist were unbearable nature of the pain and sleep disturbances. Almost half (46.2%) of the respondents had previously visited the dentist and the common received treatment was tooth extraction. A total of 57.9% of the respondents indulge in twice-daily tooth cleaning. CONCLUSION. Data from this study revealed that respondents with toothache had history of dental visit and visited dental clinic when the pain is unbearable and disturbed sleep. There is a need for proper patient education at any encounter with dentist. PMID:24589637

    Background: Because of lack of local normative data, electrodiagnostic laboratories in Nigeria apply standard values generated in the USA and Europe to diagnose different median nerve abnormalities. Aim: To develop normative values for motor and sensory median nerve conduction studies (NCSs) in Nigerian population. Subjects and Methods: In a cross-sectional study design, a total of 200 healthy volunteers were selected after clinical evaluation to exclude systemic or neuromuscular disorders. NCS of the median nerves was conducted on all the healthy volunteers according to a standardized protocol. The data included in the final analysis were amplitude, latency, and nerve conduction velocity. Ethical approval was obtained for the study. Results: The reference range for median nerve (motor) velocity, distal latency, and amplitude were 49.48–66.92, 1.95–4.52, and 4.3–11.3, respectively. The reference range for median nerve F-wave latency was 44.8–70.5. The reference range for median nerve (sensory) velocity, distal latency, and amplitude were 44.8–70.5, 1.98–4.52, and 16.6–58.4, respectively. Conclusion: Reference values for the nerve conduction parameters of the median (motor and sensory) in the study population were similar to those obtained in the literature. PMID:27213090

    Background There are only very few reports on Fallot’s tetralogy in Africa especially from sub-Saharan Africa. At best tetralogy of Fallot (TOF) is only mentioned as part of reports of surveys of other congenital heart diseases or as case reports in the region. There has been no report on cohorts of children with TOF in West Africa. This article describes the pattern and presentation of children diagnosed with TOF patients in a tertiary hospital in sub-Saharan Africa over a 9-year period. Methods Prospective and consecutive review of all subjects with diagnosis of TOF confirmed with echocardiography at the Lagos State University Teaching Hospital (LASUTH) between January 2007 and December 2015. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics were presented as percentages or means and standard deviation. Means of normally distributed variables were compared using the Students’ t-test and proportions using Chi-square test. Skewed distributions were analyzed using appropriate non-parametric tests. Level of significance set at P<0.05. Results The prevalence of TOF among children presenting at LASUTH at the study period was 4.9 per 1,000 while its prevalence among those with congenital heart disease was 16.9%. There was a male predominance with a mean age of 50.9±45.9 (months) and median age of 36 months. Most children presented within 1–5 years of age. The most common indication for evaluation was cyanosis. One hundred and nineteen out of 165 (72.1%) children were clinically cyanosed on presentation. Conclusions TOF is prevalent among Nigerian children. Cyanosis was the commonest presenting feature and indication for evaluation. Most of the subjects presented late hence were diagnosed after 1 year of age. There is a need to increase awareness of TOF in Nigeria to encourage early diagnosis and hence better outcomes in these subjects. PMID:27747169

    Sexual assault is a common social disorder among students in our tertiary institutions. This study ascertains the extent and effect of sexual assault among Nigerian students. Two hundred and Sixty Eight structured questionnaires were distributed to randomly selected students in 4 tertiary institutions, information on socio demography, sexual history and consequences of their exposure were obtained for analysis and interpretation. Thirty seven (13.8%) of the respondents were sexually assaulted as a student and 19 (7.1%) were assaulted by their lecturers and fellow students, Younger age at coitarche, history of forced coitarche, marriage, coitarche with relations and unknown persons, significantly influenced subsequent risks of sexual assault. Improve security, moral behaviours enforcing dress code and stiffer penalties were suggested ways to prevent sexual assault among the students. Sexual assault is still a common finding in our institutions; effort should be made by all stake holders to prevent this social embarrassment. PMID:21495612

    Lip prints in a narrow sense are normal lines and fissures in the form of wrinkles and grooves present in the zone of transition of lips. The aims of this study were to determine the types and association of lip prints as well as the role of the lip print as genetic marker in ethnic differentiation in multi-ethnic population of Nigeria. A total of 820 individuals (414 males and 406 females) participated. The study sample was drawn from different ethnic groups of Nigeria. The three major ethnic groups were identified and the minor groups were lumped together. This was to provide clear evidence on the ethnic differentiation based on lip print types among Nigerians. The lip prints were collected on microscopic glass slides and developed using carbon black powder. Each print was then divided into 10 compartments and analyzed using a magnifying lens. Chi-squared test was used for association between ethnicity and lip print types; p<0.05 was set as a level of significance. The result of the study showed the following lip print pattern in Nigerian population where Type V (31.39%) was predominant, followed by Type III (24.18%), Type IV (18.70%), Type I (14.87%), Type II (10.29%) and least frequent was Type I' (0.57%). Statistically significant association (p<0.05) of lip print types with ethnicity was found in upper left lateral compartments (ULL). It was concluded that lip prints show ethnic differences. Hence, they may hold potential promise as a supplementary tool in ethnic differentiation and in personal identification. PMID:26421606

    Introduction Few reports from Nigeria have examined the quality of life (QOL) of people living with HIV/AIDS (PLWHA) despite the fact that Nigeria has the second largest number of PLWHA in the world. This study evaluated the QOL of Nigerians living with HIV/AIDS using the World Health Organization Quality of Life Questionnaire for HIV-Brief Version (WHOQOL-BREF) instrument and assessed the impact of demographic, laboratory and disease-related variables on QOL. Methods This cross-sectional study involved 491 consecutive PLWHA aged ≥ 18 years attending the dedicated clinic to PLWHA in South-west Nigeria. Results The lowest mean QOL scores were recorded in the environment and social domains. Participants aged ≥ 40 years had better QOL in the environment (p = 0.039) and spirituality (p = 0.033) domains and those in relationships had better QOL in the social relationship domain (p = 0.002). Subjects with no or primary education and those who rated their health status as good gave significantly higher ratings in all QOL domains. Participants with AIDS had significant lower QOL in the level of independence domain (p = 0.018) and those with CD4 count ≥ 350 cells /mm3 had better QOL scores in the physical, psychological and level of independence domains. Subjects without tuberculosis co-infection and those on antiretroviral therapy (ART) reported significantly better QOL in the physical, psychological, level of independence and spirituality domains. Conclusion Marital relationship, absence of tuberculosis, CD4 count ≥ 350 cells /mm3 and use of ART positively impacted QOL of our patients. PMID:25426192

    Following our previous observation of an aversion to weight reduction in Nigerians with type 2 diabetes, we measured several parameters of body dimensions and preferences in otherwise healthy adults in three communities to study the phenomenon further. The study population of 524 participants (304 F) was 99.8% of Yoruba ethnic origin with a mean age of 43.9 ± 17.2 years. Females had a significantly (p > 0.001) higher body mass index (BMI), waist circumference, hip circumference compared to the males; the values being 24.55 ± 5.5 vs. 21.75 ± 3.71 kg/m(2); 84.98 ± 12.67 vs. 80.92 ± 9.85 cm; 96.32 ± 12.94 vs. 89.36 ± 8.06 cm, respectively. There was a high level of satisfaction amongst respondents with their body size (Kendall's t = 0.52, p < 0.001) which they also predicted with a high degree of certainty even without the prior use of a weighing scale. The relationship between current body size (CBI) and BMI emerged as CBI = 1.22 + 0.32 BMI. In the 41% of respondents who expressed unhappiness with their current body size, there was a strong aversion for a smaller body size and the preference was often for a bigger body figure. Strikingly, many more women than men were less dissatisfied with their bigger body sizes. Stepwise regression indicated that CBI and gender were the two most important variables that best related to casual blood sugar (RBS) among the factors entered. The mathematical relationship between these variables that emerged was: [Formula: see text] where gender = 0 for male and 1 for female. The results suggest that larger body sizes were positively viewed in these communities consistent with our previous observations in type 2 diabetes. PMID:24174319

    SUMMARY Older adults have high prevalence rates of insomnia symptoms, yet it is unclear if these insomnia symptoms are associated with objective impairments in sleep. We hypothesized that insomnia complaints in older adults would be associated with objective differences in sleep compared to those without insomnia complaints. To test this hypothesis, we conducted a cross-sectional study in which older adults with insomnia complaints (cases, n=100) were compared to older adults without insomnia complaints (controls, n=100) using dual-night in-lab nocturnal polysomnography, study questionnaires and seven days of at-home actigraphy and sleep diaries. Cases were noted to have reduced objective total sleep time compared to controls (25.8 minutes +/− 8.56, p=0.003). This was largely due to increased wakefulness after sleep onset (WASO), and not increased sleep latency. When participants with sleep-related breathing disorder or periodic limb movement disorder were excluded, the polysomnography total sleep time difference became even larger. Cases also had reduced slow-wave sleep (5.10 +/− 1.38 vs 10.57 +/− 2.29 minutes, effect size −0.29, p=0.04). When comparing self-reported sleep latency and sleep efficiency to objective polysomnographic findings, cases demonstrated low, but statistically significant correlations, while no such correlations were observed in controls. Cases tended to under-estimate their sleep efficiency by 1.6% (+/− 18.4%), while controls over-estimated their sleep efficiency by 12.4% (+/− 14.5%). In conclusion, we noted that older adults with insomnia complaints have significant differences in several objective sleep findings relative to controls, suggesting that insomnia complaints in older adults are associated with objective impairments in sleep.

    Objective. To evaluate cognitive factors that might influence academic performance of students in Nigerian pharmacy schools. Methods. A cross-sectional, multi-center survey of Nigerian pharmacy students from 7 schools of pharmacy was conducted using 2 validated questionnaires measuring cognitive constructs such as test anxiety, academic competence, test competence, time management, and strategic study habits. Results. Female students and older students scored significantly better on time management skills and study habits, respectively. Test anxiety was negatively associated with academic performance while test competence, academic competence, and time management were positively associated with academic performance. These 4 constructs significantly discriminated between the lower and higher performing students, with the first 2 contributing to the most differences. Conclusion. Test and academic competence, test anxiety, and time management were significant factors associated with low and high academic performance among Nigerian pharmacy students. The study also demonstrated the significant effects of age, gender, and marital status on these constructs.

    Using baseline data from ELSA-Brasil (N = 15,105), we investigated whether subjective social status, measured using three 10-rung "ladders," is associated with self-rated health and smoking, independently of objective indicators of social position and depression symptoms. Additionally, we explored whether the magnitude of these associations varies according to the reference group. Subjective social status was independently associated with poor self-rated health and weakly associated with former smoking. The references used for social comparison did not change these associations significantly. Subjective social status, education, and income represent distinct aspects of social inequities, and the impact of each of these indicators on health is different.

    Objective. To determine the prevalence and correlates of alcohol use among a sample of Nigerian semirural community dwellers in Nigeria. Methods. In a single arm nonrandomized intervention study, the assessment of baseline hazardous and harmful alcohol use and associated risk factors was conducted in two semirural local government areas of Oyo State, Nigeria, with the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Participants included 1203 subjects 15 years and older, recruited between October 2010 and April 2011. ASSIST score of 0-10 was classified as lower risk scores, 11-26 as moderate risk, and 27+ as high risk. Results. Prevalence of lifetime alcohol use was 57.9% and current alcohol use was 23.7%. Current alcohol use was more prevalent among the younger age group p = 0.02, male gender p = 0.003, unmarried p < 0.01, low educational level p = 0.003, low socioeconomic class p = 0.01, unemployed p < 0.001, and the Christians p < 0.01. Of the current drinkers, the majority (69.1%) were at either moderate or high health risk from alcohol use. Conclusion. Alcohol consumption is prevalent in semirural communities in Nigeria and the majority of these drinkers are at moderate or high health risk. Screening, brief intervention, and referral for treatment for unhealthy alcohol use should be integrated into community care services in Nigerian rural communities. PMID:27195170

    Aim: To evaluate the treatment outcome and long-term stability of skeletal changes following maxillary advancement with distraction osteogenesis in adult subjects of cleft lip and palate. Materials and Methods: Total 12 North Indian adult patients in the age range of 17-34 years with cleft lip and palate underwent advancement of maxilla by distraction osteogenesis. Lateral cephalograms recorded prior to distraction, at the end of distraction, 6 months after distraction, and at least 24 months (mean 25.5 ± 1.94 months) after distraction osteogenesis were used for the evaluation of treatment outcome and long-term stability of the skeletal changes. Descriptive analysis, ANOVA, and post-hoc test were used, and P-value 0.05 was considered as a statistically significant level. Results: Maxillary distraction resulted in significant advancement of maxilla (P<0.001). Counterclockwise rotation of the palatal plane took place after maxillary distraction. The position of the mandible and facial heights were stable during distraction. During the first 6 months of the post-distraction period, the maxilla showed relapse of approximately 30%. However, after 6 months post distraction, the relapse was very negligible. Conclusions: Successful advancement of maxilla was achieved by distraction osteogenesis in adult subjects with cleft lip and palate. Most of the relapse occurred during the first 6 months of post-distraction period, and after that the outcomes were stable. PMID:22919221

    Background: The rising incidence of breast cancer is complicated by late presentation, which marks breast cancer diagnosis in Nigeria with about 70% of cases presenting at advanced stages of the disease. The aim of this study is to determine the general level of awareness of breast cancer, breast cancer risk factors, signs/symptoms as well as preventive measures nothern Nigerian women. It also aimed at determining their attitudes toward breast cancer cure, prevention and cause. Finally, it aims to determine their practices toward breast cancer and its associated factors. Methods: A cross-sectional community survey was used to study 230 women aged 15–60 years in Chikun Local Government Area. The subjects were selected based on nonprobability sampling. Data collected using self-administered questionnaire were analyzed using Statistical Package for Social Science students (version 16). Test of associations employed Chi-square statistical tool with the level of significance taken at 0.05. Results: About 75.2% knew about breast cancer with health facility (29.13%) being the greatest source of information. An average of 29.35% had knowledge of the risk factors tested. Mean knowledge of the signs and symptoms was 50.1% Average knowledge of breast cancer screening methods was 34.26% with breast self-examination (BSE) (46.1%) being the most recognized. In relation to perception, about 21.7% strongly agreed with the fact that breast cancer is treatable following early detection while 18.3% strongly agreed that screening is effective in detecting breast cancer. Concerning practice, an average of 10.2% practiced any of the screening methods, with BSE (17.4%) being the most practiced. Strongest reasons for nonpractice was ignorance (17.4%). An association was established between knowledge and practice of all the screening methods (P = 0.001 respectively). Conclusions: There is insufficient knowledge, as well as poor practices in relation to important factors associated with

    The effect of hepatic impairment on fosamprenavir/ritonavir pharmacokinetics was investigated. Sixty human immunodeficiency virus type 1-infected subjects, including 13, 20, and 10 subjects with mild, moderate, and severe hepatic impairment, respectively, and a comparator group of 17 subjects with normal hepatic function, were enrolled. Subjects with normal hepatic function received fosamprenavir at 700 mg plus ritonavir at 100 mg twice daily, whereas subjects with hepatic impairment received adjusted doses in anticipation of increased exposures. For subjects with mild hepatic impairment, the studied regimen of fosamprenavir 700 mg twice daily plus ritonavir 100 mg once daily delivered 17% higher values for the maximum plasma amprenavir concentration at the steady state (Cmax), 22% higher values for the area under the plasma concentration versus time curve over the dosing interval at the steady state [AUC(0-τ)], similar values for the concentration at the end of the dosing interval (Cτ), and 114% higher unbound Cτ values. For subjects with moderate hepatic impairment, the studied dosage regimen of fosamprenavir at 300 mg twice daily plus ritonavir at 100 mg once daily delivered 27% lower plasma amprenavir Cmax values, 27% lower AUC(0-24) values, 57% lower Cτ values, and 21% higher unbound amprenavir Cτ values. For subjects with severe hepatic impairment, the studied dosage regimen of fosamprenavir at 300 mg twice daily plus ritonavir at 100 mg once daily delivered 19% lower plasma amprenavir Cmax values, 23% lower AUC(0-24) values, 38% lower Cτ values, and similar unbound amprenavir Cτ values. With a reduced ritonavir dosing frequency of 100 mg once daily, the plasma ritonavir AUC(0-24) values were 39% lower, similar, and 40% higher for subjects with mild, moderate, and severe hepatic impairment, respectively. The results of the study support the use of reduced fosamprenavir/ritonavir doses or dosing frequencies in the treatment of patients with hepatic

    Dietary polyphenols are antioxidants that can scavenge biological free radicals, and chemoprevent diseases with biological oxidation as their main etiological factor. In this paper, we review our laboratory data vis-ὰ-vis available literature on prostate cancer chemopreventive substances in Nigerian foodstuffs. Dacryodes edulis fruit, Moringa oleifera and Syzygium aromaticum contained prostate active polyphenols like ellagic acid, gallate, methylgallate, catechol, kaempferol quercetin and their derivatives. Also Canarium schweinfurthii Engl oil contained ten phenolic compounds and lignans, namely; catechol, p-hydroxybenzaldehyde, dihydroxyphenylacetic acid, tyrosol, p-hydroxybenzoic acid, dihydroxybenzoic acid, vanillic acid, phloretic acid, pinoresinol, secoisolariciresinol. In addition, tomatoes (Lycopersicon esculentum Mill) which contains the powerful antioxidant and anti-prostate cancer agent, lycopene; cabbage (Brassica oleracea) containing indole-3-carbinol; citrus fruits containing pectin; Soursop (Annona muricata) containing annonaceous acetogenins; soya beans (Glycine max) containing isoflavones; chilli pepper (Capsicum annuum) containing capsaicin, and green tea (Camellia sinensis) containing (-) epigallocatechin gallate (EGCG), (-) epicatechin, (-) epicatechin-3-gallate and (-) epigallocatechin -3-gallate which are widely reported to posses prostate cancer chemopreventive compounds are also grown in Nigeria and other African countries. Thus, the high incidence of prostate cancer among males of African extraction can be dramatically reduced, and the age of onset drastically increased, if the population at risk consumes the right kinds of foods in the right proportion, beginning early in life, especially as prostate cancer has a latency period of about 50 years.

Also Canarium schweinfurthii Engl oil contained ten phenolic compounds and lignans, namely; catechol, p-hydroxybenzaldehyde, dihydroxyphenylacetic acid, tyrosol, p-hydroxybenzoic acid, dihydroxybenzoic acid, vanillic acid, phloretic acid, pinoresinol, secoisolariciresinol. In addition, tomatoes (Lycopersicon esculentum Mill) which contains the powerful antioxidant and anti-prostate cancer agent, lycopene; cabbage (Brassica oleracea) containing indole-3-carbinol; citrus fruits containing pectin; Soursop (Annona muricata) containing annonaceous acetogenins; soya beans (Glycine max) containing isoflavones; chilli pepper (Capsicum annuum) containing capsaicin, and green tea (Camellia sinensis) containing (-) epigallocatechin gallate (EGCG), (-) epicatechin, (-) epicatechin-3-gallate and (-) epigallocatechin -3-gallate which are widely reported to posses prostate cancer chemopreventive compounds are also grown in Nigeria and other African countries. Thus, the high incidence of prostate cancer among males of African extraction can be dramatically reduced, and the age of onset drastically increased, if the population at risk consumes the right kinds of foods in the right proportion, beginning early in life, especially as prostate cancer has a latency period of about 50 years.

    Thyroid glands obtained at autopsy from young adults were studied to establish more accurately the ''normal'' morphology in the groups 20 to 40 years of age. A total of 56 autopsy specimens (many obtained from trauma victims) were examined in detail by totally embedding and sectioning the thyroid glands. The morphology of these thyroid glands also was compared to that of surgically removed thyroid glands from 47 young adult patients with prior low-dose neck irradiation. The ''normal'' thyroid specimens frequently showed morphologic features, such as thyroid tissue outside the recognizable capsule of the gland (40 of 56 patients) and in the strap muscles of the neck (six of 56 patients), which are conditions commonly considered as evidence for invasive thyroid carcinoma. The thyroid glands from the ''normal'' young adult population were significantly different from those thyroid glands surgically removed from patients who had received irradiation. The irradiated thyroid glands invariably showed multiple nodules of a wide variety of histologic types, extensive lymphocytic infiltrates, and distorting fibrosis as well as a high incidence of malignancy (27 of 47 patients). A single 0.1 cm focus of papillary carcinoma was found in one specimen in the nonirradiated thyroid group. This study suggests that ''occult'' thyroid carcinomas in the group 20 to 40 years of age are rare and are significantly fewer in number than in the older population (P less than 0.02).

    Methylphenidate (MPH) is commonly prescribed for the treatment of Attention Deficit Hyperactivity Disorder (ADHD), and is often used illicitly by young adults. Illicit users often coadminister MPH with marijuana. Little is known about physiologic and subjective effects of these substances used in combination. In this double-blind, cross-over experiment, sixteen healthy adult subjects free from psychiatric illness (including ADHD) and reporting modest levels of marijuana use participated in 6 experimental sessions wherein all combinations of placebo or 10 mg oral doses of delta-9-tetrahydocannibinol (THC); and 0 mg, 10 mg and 40 mg of MPH were administered. Sessions were separated by at least 48 hours. Vital signs, subjective effects, and performance measure were collected. THC and MPH showed additive effects on heart rate and rate pressure product (e.g., peak heart rate for 10 mg THC + 0 mg, 10 mg, and 40 mg MPH = 89.1, 95.9, 102.0 beats/min, respectively). Main effects of THC and MPH were also observed on a range of subjective measures of drug effects, and significant THC dose × MPH dose interactions were found on measures of “Feel Drug,” “Good Effects,” and “Take Drug Again.” THC increased commission errors on a continuous performance test (CPT) and MPH reduced reaction time variability on this measure. Effects of THC, MPH, and their combination were variable on a measure of working memory (n-back task), though in general, MPH decreased reaction times and THC mitigated these effects. These results suggest that the combination of low to moderate doses of MPH and THC produces unique effects on cardiovascular function, subjective effects and performance measures. PMID:25175495

    Background Despite having the largest population in Africa, Nigeria has no accurate population based data to plan and evaluate eye care services. A national survey was undertaken to estimate the prevalence and determine the major causes of blindness and low vision. This paper presents the detailed methodology used during the survey. Methods A nationally representative sample of persons aged 40 years and above was selected. Children aged 10–15 years and individuals aged <10 or 16–39 years with visual impairment were also included if they lived in households with an eligible adult. All participants had their height, weight, and blood pressure measured followed by assessment of presenting visual acuity, refractokeratomery, A-scan ultrasonography, visual fields and best corrected visual acuity. Anterior and posterior segments of each eye were examined with a torch and direct ophthalmoscope. Participants with visual acuity of < = 6/12 in one or both eyes underwent detailed examination including applanation tonometry, dilated slit lamp biomicroscopy, lens grading and fundus photography. All those who had undergone cataract surgery were refracted and best corrected vision recorded. Causes of visual impairment by eye and for the individual were determined using a clinical algorithm recommended by the World Health Organization. In addition, 1 in 7 adults also underwent a complete work up as described for those with vision < = 6/12 for constructing a normative data base for Nigerians. Discussion The field work for the study was completed in 30 months over the period 2005–2007 and covered 305 clusters across the entire country. Concurrently persons 40+ years were examined to form a normative data base. Analysis of the data is currently underway. Conclusion The methodology used was robust and adequate to provide estimates on the prevalence and causes of blindness in Nigeria. The survey would also provide information on barriers to accessing services, quality of life of

    Abstract Background Complementary and alternative medicines are increasingly used for the treatment of asthma in Western countries. A novel three-herb antiasthma herbal medicine intervention (ASHMI™; Sino-Lion Pharmaceutical Company; Shan Dong China) was demonstrated to be effective and safe in a murine model of asthma and in a preliminary clinical study in China. Objective The objective of this study was to evaluate the safety and tolerability of ASHMI in adult subjects with allergic asthma. Design Randomized, double-blind, placebo-controlled, dose escalation, phase I trial aimed at developing a botanical drug under the United States Food and Drug Administration Investigational New Drug title. Interventions Subjects received one of three doses of ASHMI or placebo: 600 mg (2 capsules); 1200 mg (4 capsules); or 1800 mg (6 capsules) twice daily for 1 week. Four (4) ASHMI and 2 placebo subjects were treated at each dose level. Subjects continued to use their conventional asthma medications for the duration of the study. Outcome measures Vital signs, physical examination, laboratory data, and electrocardiogram data were monitored throughout the study to assess occurrence of adverse events (AEs). Immunomodulatory studies were performed to evaluate the effect of ASHMI on cytokine, chemokine, and growth factor levels. Results Twenty (20) nonsmoking, allergic subjects with asthma were included in the study. Eight (8) subjects (4 ASHMI and 4 placebo) reported mild gastrointestinal symptoms. No grade 3 AEs were observed during the study period. Vital signs, electrocardiogram findings, and laboratory results obtained at pre- and post-treatment visits remained within normal range. No abnormal immunologic alterations were detected. Conclusion In this phase I study, ASHMI appeared to be safe and well tolerated by subjects with asthma. These findings allowed initiation of a larger phase II study to assess the efficacy of ASHMI. PMID:19586409

    2012-01-01

    Background An understanding of the febrile illness experience of Nigerian nomadic Fulani is necessary for developing an appropriate strategy for extending malaria intervention services to them. An exploratory study of their malaria illness experience was carried out in Northern Nigeria preparatory to promoting malaria intervention among them. Methods Ethnographic tools including interviews, group discussions, informal conversations and living-in-camp observations were used for collecting information on local knowledge, perceived cause, severity and health seeking behaviour of nomadic Fulani in their dry season camps at the Gongola-Benue valley in Northeastern Nigeria. Results Nomadic Fulani regarded pabboje (a type of "fever" that is distinct from other fevers because it "comes today, goes tomorrow, returns the next") as their commonest health problem. Pabboje is associated with early rains, ripening corn and brightly coloured flora. Pabboje is inherent in all nomadic Fulani for which treatment is therefore unnecessary despite its interference with performance of duty such as herding. Traditional medicines are used to reduce the severity, and rituals carried out to make it permanently inactive or to divert its recurrence. Although modern antimalaria may make the severity of subsequent pabboje episodes worse, nomads seek treatment in private health facilities against fevers that are persistent using antimalarial medicines. The consent of the household head was essential for a sick child to be treated outside the camp. The most important issues in health service utilization among nomads are the belief that fever is a Fulani illness that needs no cure until a particular period, preference for private medicine vendors and the avoidance of health facilities. Conclusions Understanding nomadic Fulani beliefs about pabboje is useful for planning an acceptable community participatory fever management among them. PMID:22292982

    The incidence of end-stage renal disease (ESRD) is on the rise in developing countries. To identify issues related to renal replacement therapy in ESRD patients in the developing world, we analyzed the practice and costs of hemodialysis in Nigerian ESRD patients. Ten ESRD patients were dialyzed at the Jos University Teaching Hospital, Jos, Plateau State, Nigeria, between June 15 and July 15, 2003. In these patients, we analyzed initiation, vascular access issues, frequency, duration, adequacy and economics of chronic hemodialysis. The Nigerian patients were referred to the nephrologist for the first time only when they had developed frank uremia. No patient had a permanent vascular access at the time dialysis was initiated. Only two patients had a functioning dialysis fistula, while the other eight patients were dialyzed through temporary femoral vein catheters that were removed after each dialysis. Frequency of dialysis was three times weekly in 2 patients, twice weekly in 1 patient and once weekly or less frequently in 7 patients. The duration of a dialysis session was prescribed to be 4 hours, but sessions often lasted for as long as 10 hours because of breakdowns of the antiquated dialysis machines. The urea reduction ratio was 45.3 +/- 8.6%. In every case, the cost of dialysis was borne by the patients and their families. Comparison of the cost of dialysis, with extensive re-use of supplies, to monthly incomes of Nigerians with different professions revealed that the great majority of Nigerians cannot afford three times weekly dialysis. Underdialysis in Nigerian ESRD patients is common and caused by socioeconomic factors and technologic deficits. One step towards correction of underdialysis could be sharing of the cost of dialysis by the public.

    Subjective memory complaints (SMCs) are common in older adults that can often predict further cognitive impairment. No proven effective agents are available for SMCs. The effect of BrainPower Advanced, a dietary supplement consisting of herbal extracts, nutrients, and vitamins, was evaluated in 98 volunteers with SMCs, averaging 67 years of age (47–88), in a randomized, double-blind, placebo-controlled trial. Subjective hypomnesis/memory loss (SML) and attention/concentration deficits (SAD) were evaluated before and after 12-week supplementation of BrainPower Advanced capsules (n = 47) or placebo (n = 51), using a 5-point memory questionnaire (1 = no/slight, 5 = severe). Objective memory function was evaluated using 3 subtests of visual/audio memory, abstraction, and memory recall that gave a combined total score. The BrainPower Advanced group had more cases of severe SML (severity ⩾ 3) (44/47) and severe SAD (43/47) than the placebo group (39/51 and 37/51, < 0.05, < 0.05, resp.) before the treatment. BrainPower Advanced intervention, however, improved a greater proportion of the severe SML (29.5%)(13/44) (P < 0.01) and SAD (34.9%)(15/43)(P < 0.01) than placebo (5.1% (2/39) and 13.5% (5/37), resp.). Thus, 3-month BrainPower Advanced supplementation appears to be beneficial to older adults with SMCs. PMID:27190539

The effect of BrainPower Advanced, a dietary supplement consisting of herbal extracts, nutrients, and vitamins, was evaluated in 98 volunteers with SMCs, averaging 67 years of age (47-88), in a randomized, double-blind, placebo-controlled trial. Subjective hypomnesis/memory loss (SML) and attention/concentration deficits (SAD) were evaluated before and after 12-week supplementation of BrainPower Advanced capsules (n = 47) or placebo (n = 51), using a 5-point memory questionnaire (1 = no/slight, 5 = severe). Objective memory function was evaluated using 3 subtests of visual/audio memory, abstraction, and memory recall that gave a combined total score. The BrainPower Advanced group had more cases of severe SML (severity ⩾ 3) (44/47) and severe SAD (43/47) than the placebo group (39/51 and 37/51, < 0.05, < 0.05, resp.) before the treatment. BrainPower Advanced intervention, however, improved a greater proportion of the severe SML (29.5%)(13/44) (P < 0.01) and SAD (34.9%)(15/43)(P < 0.01) than placebo (5.1% (2/39) and 13.5% (5/37), resp.). Thus, 3-month BrainPower Advanced supplementation appears to be beneficial to older adults with SMCs. PMID:27190539

    Two Nigerian sibling presented with progressive hepato-splenomegaly in infancy from which they subsequently died. Morphological investigations carried out showed that the children had Gaucher's disease. Leucocyte B-glucocerebrosidase activities from the parents of the two siblings and also from one surviving sibling were found to be only about 50% of the enzyme activities in control subjects while hexosaminidase and B-glucuronidase activities were within normal limits. There results showed that the three surviving relatives are heterozygotes and also provided a strong supporting evidence that the deceased children had Gaucher's disease. The occurence of this disease in African children living in Kenya, Uganda, the Congo and Nigeria, and in Black Americans suggest that this biochemical abnormality is not as rare in the Negroid race as has been believed hitherto, and may be widespread on the African continent.

    Studies on the chemical composition and the antioxidative properties of Nigerian Okra Seed (Abelmoschus esculentus Moench) Flour were carried out. This is done to establish the nutritional composition and the antioxidative potentials of the seeds, both of which are highly implicated in health. Okra seeds were roasted at 160 degreeC for 10-60 mins. The roasted seeds were subjected to proximate, yield and antioxidative activity determination. Pre-treatment by roasting was found to increase the yield, but was found to be time dependent. The range means obtained for protein, fat, ash, fiber and sugar contents were 42.14-38.10, 31.04-17.22, 4.06-3.42, 3.45-3.60 and 8.82-8.65, respectively. The antioxidant activity was significantly increased by roasting, while in vitro digestibility showed that most antioxidative activities were available in the intestinal phase of gastrointestinal tracts.

    The effect of Nigerian citrus (Citrus sinensis Osbeck) honey on ethanol metabolism was tested using 45 consenting individuals in apparent good health and between the ages of 25 and 35 years. The subjects were moderate social drinkers matched in terms of body weight and build. The results obtained showed that on average, honey significantly (p < 0.05) increased the blood ethanol clearance rate by 68% and decreased the intoxication period by 43%, but insignificantly (p > 0.05) reduced the degree of intoxication by 9%. Honey could be a promising anti-intoxicating agent, but its long-term biochemical evaluation, possibly as a complement in the management of alcohol intoxication, deserves further study.

    The authors examined associations between psychosocial variables (coping self-efficacy, social support, and cognitive depression) and subjective health status among a large national sample (N = 3,670) of human immunodeficiency virus (HIV)-positive persons with different sexual identities. After controlling for ethnicity, heterosexual men reported fewer symptoms than did either bisexual or gay men and heterosexual women reported fewer symptoms than did bisexual women. Heterosexual and bisexual women reported greater symptom intrusiveness than did heterosexual or gay men. Coping self-efficacy and cognitive depression independently explained symptom reports and symptom intrusiveness for heterosexual, gay, and bisexual men. Coping self-efficacy and cognitive depression explained symptom intrusiveness among heterosexual women. Cognitive depression significantly contributed to the number of symptom reports for heterosexual and bisexual women and to symptom intrusiveness for lesbian and bisexual women. Individuals likely experience HIV differently on the basis of sociocultural realities associated with sexual identity. Further, symptom intrusiveness may be a more sensitive measure of subjective health status for these groups. PMID:19064372

    Aripiprazole lauroxil is a linker lipid ester of aripiprazole for extended-release intramuscular (IM) injection. This multicenter, randomized, open-label study evaluated the pharmacokinetics (PK), relative bioavailability, and tolerability of a single IM deltoid or gluteal injection of aripiprazole lauroxil in adult subjects with chronic stable schizophrenia or schizoaffective disorder. Forty-six subjects were randomized 1:1 to aripiprazole lauroxil 441 mg IM in the deltoid or gluteal muscle. Samples were collected through 89 days post-dose to measure levels of aripiprazole lauroxil, N-hydroxymethyl aripiprazole, aripiprazole, and dehydro-aripiprazole. Forty-three (93.5%) subjects completed all study assessments; most were CYP2D6 extensive or immediate metabolizers (96%); two (4%) were poor metabolizers. The PK of aripiprazole following aripiprazole lauroxil was characterized by a steady rise in plasma concentrations (Tmax 44-50 days), a broad peak, and prolonged exposure attributable to the dissolution of aripiprazole lauroxil and formation rate-limited elimination of aripiprazole (t1/2=15.4-19.2 days). Deltoid vs. gluteal administration resulted in slightly higher Cmax aripiprazole concentrations [1.31 (1.02, 1.67); GMR 90% CI]; total exposure (AUCinf) was similar between sites of administration [0.84 (0.57, 1.24)]. N-hydroxymethyl-aripiprazole and dehydro-aripiprazole exposures were 10% and 33-36%, respectively, of aripiprazole exposure following aripiprazole lauroxil. The most common adverse events were injection site pain in 20 subjects (43.5%) and headache in 6 subjects (13.0%) of mild intensity occurring at a similar rate with deltoid and gluteal administration. Exposure ranges with deltoid and gluteal administration overlapped, suggesting that these sites may be used interchangeably. Despite a higher incidence of adverse events, deltoid muscle provides a more accessible injection site and could facilitate patient acceptance.

    Background: The aim of this study was to verify the intra-individual reproducibility of natural head position (NHP) in centric relation (CR) position, to prove the inter-individual differences in the Frankfort horizontal plane and sella-nasion line compared with the true horizontal line, and to establish linear norms from A-point, B-point, Pog as well as soft tissue A-point, soft tissue B-point, and soft tissue Pog to nasion true vertical line (NTVL) in adult Indian subjects. Methods: Lateral cephalograms (T1) of Angle’s Class I subjects were taken in NHP and with bite in CR. A second lateral cephalogram (T2) of these subjects with ANB angle in the range 1-4° were taken after 1 week using the same wax bite and both the radiographs were analyzed based on six angular parameters using cephalometric software (Do-it, Dental studio NX version 4.1) to assess the reproducibility of NHP. Linear values of six landmarks were taken in relation to NTVL, and the mean values were calculated. A total of 116 subjects were included in this study. Results: When the cephalometric values of T1 and T2 were analyzed, it was found that, the parameters showed a P < 0.001, indicating the reproducibility of NHP in CR. Mean values for point A, point B, Pog and their soft tissue counterparts were also obtained. Conclusion: The study proved that NHP is a reproducible and accurate when recorded with the mandible in CR. Linear norms for skeletal Class I subjects in relation to NTVL were established.

    The role of physical activity as a factor that protects against stress-related mental disorders is well documented. Nevertheless, there is still a dearth of research using objective measures of physical activity. The present study examines whether objectively assessed vigorous physical activity (VPA) is associated with mental health benefits beyond moderate physical activity (MPA). Particularly, this study examines whether young adults who accomplish the American College of Sports Medicine's (ACSM) vigorous-intensity exercise recommendations differ from peers below these standards with regard to their level of perceived stress, depressive symptoms, perceived pain, and subjective and objective sleep. A total of 42 undergraduate students (22 women, 20 men; M=21.24years, SD=2.20) volunteered to take part in the study. Stress, pain, depressive symptoms, and subjective sleep were assessed via questionnaire, objective sleep via sleep-EEG assessment, and VPA via actigraphy. Meeting VPA recommendations had mental health benefits beyond MPA. VPA was associated with less stress, pain, subjective sleep complaints and depressive symptoms. Moreover, vigorous exercisers had more favorable objective sleep pattern. Especially, they had increased total sleep time, more stage 4 and REM sleep, more slow wave sleep and a lower percentage of light sleep. Vigorous exercisers also reported fewer mental health problems if exposed to high stress. This study provides evidence that meeting the VPA standards of the ACSM is associated with improved mental health and more successful coping among young people, even compared to those who are meeting or exceeding the requirements for MPA.

    The study was designed to assess acceptability and side-effects of consumption of sacha inchi oil, rich in α-linolenic acid and sunflower oil, rich in linoleic acid, in adult human subjects. Thirty subjects received 10 or 15ml daily of sacha inchi or sunflower oil for 4months. Acceptability was assessed with daily self-report and with a Likert test at the end of the study. Safety was assessed with self- recording of side-effects and with hepatic and renal markers. Primary efficacy variables were the change in lipid profile. Subjects reported low acceptability of sacha inchi oil at week-1 (37.5%). However, since week-6, acceptability was significantly increased to 81.25-93.75%. No differences were observed in acceptability with respect to sex or oil volume (P>0.05). Most frequent adverse effects during first weeks of consuming sacha inchi oil or sunflower oil were nauseas. The side-effects were reduced with time. Biochemical markers of hepatic and kidney function were maintained unchanged. Serum total cholesterol and LDL cholesterol levels and arterial blood pressure were lowered with both oils (P<0.05). Higher HDL-cholesterol was observed with sacha inchi oil at month-4. In conclusion, sacha inchi oil consumed has good acceptability after week-1 of consumption and it is safety. PMID:24389453

    Daily variations in ambient particulate air pollution are associated with variations in respiratory lung function. It has been suggested that the effects of particulate matter may be due to particles in the ultrafine (0.01-0.1 microm) size range. Because previous studies on ultrafine particles only used self-monitored peak expiratory flow rate (PEFR), we assessed the associations between particle mass and number concentrations in several size ranges measured at a central site and measured (biweekly) spirometric lung function among a group of 54 adult asthmatics (n = 495 measurements). We also compared results to daily morning, afternoon, and evening PEFR measurements done at home (n = 7,672-8,110 measurements). The median (maximum) 24 hr number concentrations were 14,500/cm(3) (46,500/cm(3)) ultrafine particles and 800/cm(3) (2,800/cm(3)) accumulation mode (0.1-1 microm) particles. The median (maximum) mass concentration of PM(2.5) (particulate matter < 2.5 microm) and PM(10) (particulate matter < 10 microm in aerodynamic diameter) were 8.4 microg/m(3) (38.3 microg/m(3)) and 13.5 microg/m(3) (73.7 microg/m(3)), respectively. The number of accumulation mode particles was consistently inversely associated with PEFR in spirometry. Inverse, but nonsignificant, associations were observed with ultrafine particles, and no associations were observed with large particles (PM(10)). Compared to the effect estimates for self-monitored PEFR, the effect estimates for spirometric PEFR tended to be larger. The standard errors were also larger, probably due to the lower number of spirometric measurements. The present results support the need to monitor the particle number and size distributions in urban air in addition to mass. PMID:11335178

    Dihydroartemisinin-piperaquine is an artemisinin-based combination treatment (ACT) recommended by the WHO for uncomplicated Plasmodium falciparum malaria, and it is being used increasingly for resistant vivax malaria where combination with primaquine is required for radical cure. The WHO recently reinforced its recommendations to add a single dose of primaquine to ACTs to reduce P. falciparum transmission in low-transmission settings. The pharmacokinetics of primaquine and dihydroartemisinin-piperaquine were evaluated in 16 healthy Thai adult volunteers in a randomized crossover study. Volunteers were randomized to two groups of three sequential hospital admissions to receive 30 mg (base) primaquine, 3 tablets of dihydroartemisinin-piperaquine (120/960 mg), and the drugs together at the same doses. Blood sampling was performed over 3 days following primaquine and 36 days following dihydroartemisinin-piperaquine dosing. Pharmacokinetic assessment was done with a noncompartmental approach. The drugs were well tolerated. There were no statistically significant differences in dihydroartemisinin and piperaquine pharmacokinetics with or without primaquine. Dihydroartemisinin-piperaquine coadministration significantly increased plasma primaquine levels; geometric mean ratios (90% confidence interval [CI]) of primaquine combined versus primaquine alone for maximum concentration (Cmax), area under the concentration-time curve from 0 h to the end of the study (AUC0–last), and area under the concentration-time curve from 0 h to infinity (AUC0–∞) were 148% (117 to 187%), 129% (103 to 163%), and 128% (102 to 161%), respectively. This interaction is similar to that described recently with chloroquine and may result in an enhanced radical curative effect.

    The objectives of this study were to identify and quantitate the germ cell populations of the testes in sexually mature male turkeys (Trial 1), determine the duration of meiosis based on BrdU labeling and stereological analyses (Trial 2), and examine the impact of various photoperiods on germinal and somatic cell populations in immature and adult males (Trial 3). In Trial 1, both testes within a male had similar stereological components (P>0.05) for all parameters analyzed. In Trial 2, the duration of Type-1 spermatocytes and round spermatids in turkeys lasted 4.5+/-0.5 and 2.0+/-0.5 days, respectively. In Trial 3, the short photoperiod (7L:17D) delayed testicular growth (in the stereological parameters analyzed). In contrast, the effect of a moderately short photoperiod (10.5L:13.5D) was comparable to the effect of a long (14L:10D) or increasing photoperiod (7L:17D to 14L:10D) on the stereological parameters examined. With the exception of the short photoperiod, all other photoperiods used in this study induced comparable early testicular maturation, with maximum testis weight at 29-35 weeks of age. As the males got older, there was a progressive, linear decline in testis weight through 60 weeks, at which time there were no significant differences among photoperiods. In conclusion, the duration of meiosis in the turkey was similar to that observed in the fowl and guinea-fowl. The existence of a threshold of photosensitivity to gonad stimulation in male turkeys is suggested to be between 7.0 and 10.5 h of light.

    In the present study, structural changes in the milk protein α-lactalbumin (α-LA) and its proteolysis were investigated for the potential formation of protein-fatty acid complexes during in vivo gastric digestion. Capsule endoscopy allowed visualisation of the digestion of the test drinks, with nasogastric tubes allowing sampling of the gastric contents. A total of ten healthy volunteers had nasogastric tubes inserted into the stomach and ingested test drinks containing 50 g/l of sucrose and 25 g/l of α-LA with and without 4 g/l of oleic acid (OA). The samples of gastric contents were collected for analysis at 3 min intervals. The results revealed a rapid decrease in the pH of the stomach of the subjects. The fasting pH of 2·31 (SD 1·19) increased to a pH maxima of pH 6·54 (SD 0·29) after ingestion, with a subsequent decrease to pH 2·22 (SD 1·91) after 21 min (n 8). Fluorescence spectroscopy and Fourier transform IR spectroscopy revealed partial protein unfolding, coinciding with the decrease in pH below the isoelectric point of α-LA. The activity of pepsin in the fasting state was found to be 39 (SD 12) units/ml of gastric juice. Rapid digestion of the protein occurred: after 15 min, no native protein was detected using SDS-PAGE; HPLC revealed the presence of small amounts of native protein after 24 min of gastric digestion. Mirocam® capsule endoscopy imaging and video clips (see the online supplementary material) revealed that gastric peristalsis resulted in a heterogeneous mixture during gastric digestion. Unfolding of α-LA was observed during gastric transit; however, there was no evidence of a cytotoxic complex being formed between α-LA and OA. PMID:24967992

    It has been suggested that aspartame addition to meals already containing large amounts of monosodium L-glutamate would result in an early rapid rise in plasma glutamate and/or aspartate concentrations and increase the potential for dicarboxylic amino acid-induced toxicity. Six normal adult subjects were fed hamburger and milk shake meals providing protein at 1 g/kg body weight in a randomized cross-over design. One meal had no additions while the other contained added monosodium L-glutamate and aspartame (each present at 34 mg/kg body weight). The addition of aspartame plus glutamate had little effect on either plasma or erythrocyte concentrations of glutamate or aspartate beyond those arising from the meal itself. Plasma phenylalanine concentrations were significantly higher (p less than 0.05, paired t test) after ingestion of meals containing aspartame plus glutamate reflecting the increased phenylalanine load.

    The purpose of this study was to examine the independent protective effect of subjective well-being on severe psychological distress among adult Canadians with a history of child maltreatment. Data for this study were obtained from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). A sample of 8126 respondents aged 20-69 years old who experienced at least one child maltreatment event was analyzed using binary logistic regression with severe psychological distress as the outcome variable. Of the 8126 respondents with a history of child maltreatment, 3.9% experienced severe psychological distress within the past month. Results from the multivariate logistic regression revealed that emotional and psychological well-being each had a significant effect on severe psychological distress. For each unit increase in emotional well-being, the odds of a respondent having severe psychological distress were predicted to decrease by a factor of 28% and for each unit increase in psychological well-being, the odds of a respondent having severe psychological distress were predicted to decrease by a factor of 10%, net the effect of demographic, socioeconomic, and health factors. Other factors associated with psychological distress included: younger age, poor self-perceived physical health, and chronic condition. Having post-secondary education, having a higher income, and being non-White predicted lower odds of severe psychological distress. Although, child maltreatment is associated with stressful life events later in adulthood, subjective well-being could serve as a protective factor against severe psychological distress among adults who experienced maltreatment when they were children.

    This study aimed to assess whether the perception of quality of life (QOL) and subjective well-being (SWB) of young adults with autism spectrum disorders (ASD) is affected by participation in a comprehensive program. Participants included 25 young adults with ASD who participated in the "Roim Rachok Program" (RRP), where they were trained to become aerial photography interpreters. Following the training period, they served in a designated army unit where they practiced their newly acquired profession. The participants filled out two questionnaires, (a) Quality of Life (QOL-Q) and (b) Personal Well-being Index (PWI), at three points of the intervention: (a) before the course, (b) at the end of the course, and (c) six months after integrating in the designated army unit. Wilcoxon signed ranks tests were used to assess the differences between the reported QOL and SWB at the three points of time. The results suggest that there were no significant differences at the end of the course, compared to its beginning. However, there were significantly improved perception of QOL and SWB during the period between the end of the course and six months after starting work. The results of this study highlight the importance of tailored vocational programs that are adapted to the unique needs and strengths of individuals with ASD. PMID:26404341

    This study aimed to assess whether the perception of quality of life (QOL) and subjective well-being (SWB) of young adults with autism spectrum disorders (ASD) is affected by participation in a comprehensive program. Participants included 25 young adults with ASD who participated in the "Roim Rachok Program" (RRP), where they were trained to become aerial photography interpreters. Following the training period, they served in a designated army unit where they practiced their newly acquired profession. The participants filled out two questionnaires, (a) Quality of Life (QOL-Q) and (b) Personal Well-being Index (PWI), at three points of the intervention: (a) before the course, (b) at the end of the course, and (c) six months after integrating in the designated army unit. Wilcoxon signed ranks tests were used to assess the differences between the reported QOL and SWB at the three points of time. The results suggest that there were no significant differences at the end of the course, compared to its beginning. However, there were significantly improved perception of QOL and SWB during the period between the end of the course and six months after starting work. The results of this study highlight the importance of tailored vocational programs that are adapted to the unique needs and strengths of individuals with ASD.

    Using a questionnaire administered by us, we sought to investigate the differences between patients referred to the psychiatric department of a Nigerian military general hospital during peacetime and those referred during the civil war in Liberia in which Nigerian soldiers were involved as peacekeepers. Referrals to psychiatry in peacetime were quite few but increased considerably during the period of combat in direct relation to the increase in the number of surgical wounded in action cases. Organic mental disorders and anxiety disorders were more frequently referred in peacetime than in war, whereas substance abuse disorders were more frequent during the combat period. Non-psychotic psychiatric conditions were less referred in the wartime group, partly because of nonrecognition at the mission areas and also because of recovery in front-line areas or consideration of their evacuation as a nonpriority. Mental health workers engaged at the mission areas require more training in the identification of such cases. PMID:16130633

    2014-01-01

    Background One of the consequences of the generational paradigm shift of lifestyle from the traditional African model to a more "western" standard is a replacement of communicable diseases by non-communicable or life style related diseases like diabetes. To address this trend, diabetes education along with continuous assessment of diabetes related knowledge has been advocated. Since most of the Nigerian studies assessing knowledge of diabetes were hospital-based, we decided to evaluate the diabetes related knowledge and its sociodemographic determinants in a general population of diabetics. Methods Diabetics (n = 184) attending the 2012 world diabetes day celebration in a Nigerian community were surveyed using a two part questionnaire. Section A elicited information on their demographics characteristics and participation in update courses, and exercise, while section B assessed knowledge of diabetes using the 14 item Michigan Diabetes Research and Training Centre's Brief Diabetes Knowledge Test. Results We found that Nigerian diabetics had poor knowledge of diabetes, with pervasive fallacies. Majority did not have knowledge of "diabetes diet", "fatty food", "free food", effect of unsweetened fruit juice on blood glucose, treatment of hypoglycaemia, and the average duration glycosylated haemoglobin (haemoglobin A1) test measures blood glucose. Attaining tertiary education, falling under the 51-60 years age group, frequent attendance at seminars/updates and satisfaction with education received, being employed by or formerly working for the government, and claiming an intermediate, or wealthy income status was associated with better knowledge of diabetes. Conclusion Nigerian diabetics' knowledge of diabetes was poor and related to age, level of education, satisfaction with education received, employment status and household wealth. PMID:24593904

    Sickle cell disease (SCD) is reported to be the most common genetic disorder affecting Nigerians. Children with SCD are at a high risk of neurological morbidity. The main objective of this study was to determine the pattern of adverse neurological outcomes among a cohort of Nigerian children with SCD. All children with SCD seen in the Department of Paediatrics, University College Hospital, Ibadan, Nigeria, over a period of 2 years were carefully evaluated for symptoms and signs of neurological complications, defined as clinical outcomes referable to the central nervous system. Of the 214 children evaluated, 187 were diagnosed with Hb SS disease and 27 with Hb SC disease. Neurological complications were identified in 78 (36.4 %) of the cases. The most common complications were headache (17.8 %), seizure (9.3 %) and stroke (8.4 %). Other less frequent complications included bacterial meningitis (2.8 %), spontaneous visual loss (1.4 %), paraplegia (0.9 %) and transient ischaemic attacks (0.9 %). Neurological complications occurred more frequently in children with sickle cell anaemia than in those with Hb SC disease (P = 0.002, 95 % CI 1.450-82.870). Adverse neurological events are common in Nigerian children with SCD, with a significantly higher risk in Hb SS than Hb SC disease. Stroke represents a major underlying cause of symptomatic epilepsy in SCD. Institution of primary preventive measures for stroke in SCD will significantly reduce the burden of stroke and epilepsy associated with SCD in Nigeria.

    Introduction Some adolescents may have sleep disorder at some point during adolescence. Determining the pattern and practice of sleep among adolescents could be useful to establish a lasting sleep hygiene program among adolescents. The objectives of this study are to describe sleep pattern and practice among adolescent in Nigerian secondary schools. Methods Sleep habits were investigated using a random sampling of adolescents from secondary schools from February to April 2013. A self-administered questionnaire was developed based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) IV criteria. Epworth Daytime Sleepiness Scale and Pittsburgh Sleep Quality Index (PSQI) were used. Results A total of 443 subjects, comprising 263 (59.4%) females and 180 (40.6%) males completed the questionnaire. The mean duration of night sleep of the subjects during weekday was 7.84 (1.9) hours and 8.65 (2.07) hours during the weekend. 22.8% (101/443) had abnormal sleep onset latency (< 5 minutes and > 30 minutes). The gender of the subjects did not influence the sleep onset latency (χ2 = 32.89, p= 0.57). Twenty six (5.9%)of the subjects reported difficulty falling asleep. Conclusion Adolescents have varying degrees of sleeping practice and hygiene. PMID:25883740

    2014-01-01

    Background Physical inactivity levels are rising in many countries with major implications for the prevalence of non-communicable diseases and the general health of the population worldwide. We conducted this study to examine leisure-time physical activity levels among African adults in an urban setting. Methods We conducted a cross-sectional study among a random sample of 1,058 adults at a government worksite, in Abuja, an urban Nigerian city. We used log-binomial regression models to estimate the multivariable-adjusted associations of correlates of physical activity. Results The mean age of the study population was 42 ± 9.3 years, 60% were men and 40% were women. The mean metabolic equivalent hours per week for all the participants was 6.8 ± 7.2. In univariate analysis comparing the lowest to highest tertiles of physical activity, the prevalence ratio (PR) and (95% confidence interval, CI) was 0.95 (0.81-1.11) p = 0.49, comparing women to men; compared to those aged <30 years the PR (95% CI) was 0.70 (0.57-0.86), 0.70 (0.58-0.85) and 0.78 (0.63-0.96) for age 30–39, 40–49 and ≥50 years respectively, p for trend = 0.03; compared to those who were normal weight, the PR was 0.93 (0.79-1.10) and 0.90 (0.74-1.09) for overweight and obese persons respectively, p = 0.26. The PR for age was attenuated to non-significant levels in multivariable analyses. Being married was a statistically significant correlate of higher physical activity levels, the PR comparing unmarried to married persons in multivariate analysis was 0.81 (0.67-0.97), p = 0.03. Conclusions More than 80% of urban, professional Nigerian adults do not meet the WHO recommendations of physical activity. Urbanized Africans in this study population had low levels of leisure-time physical activity, independent of age, sex and body-mass index. This has major implications for the prevalence of non-communicable diseases in this population. PMID:24885080

    BR-TD-1001 was developed as a booster for the immunity maintenance of diphtheria and tetanus. The aim of this study was to evaluate the safety and immunogenicity of BR-TD-1001 (test vaccine) in comparison with placebo and an active comparator in healthy Korean adults. A randomized, double-blind, placebo-controlled, active comparator, phase I clinical trial was conducted. Fifty subjects were randomly assigned to one of 3 treatment groups in a ratio of 2:2:1, and were administered a single intramuscular dose of test vaccine, active comparator, or placebo, respectively. All subjects were monitored for 4 weeks after injection. The antibody titers of the patients 2 and 4 weeks after vaccination were compared with the baseline. The frequencies of all adverse events including adverse drug reactions in the test group were not statistically different from those of the other treatment groups (P = 0.4974, 0.3061). No serious adverse event occurred, and no subject was withdrawn from the study for safety. The seroprotection rates against both tetanus and diphtheria at 4 weeks after vaccination were over 0.95. For anti-tetanus antibody, the geometric mean titer in the test group was significantly higher than those of the other groups (P = 0.0364, 0.0033). The geometric mean titer of anti-diphtheria antibody in the test group was significantly higher than the value of the placebo (P = 0.0347) while it was not for the value of the active comparator (P = 0.8484). In conclusion, BR-TD-1001 was safe, well-tolerated, and showed sufficient immunogenicity as a booster for diphtheria and tetanus.

    Background: Tuberculosis (TB) causes significant morbidity/mortality among human immunodeficiency virus-infected individuals in Africa. Reducing TB burden in the era of highly active antiretroviral therapy (HAART) is a public health priority. Aim: We determined the factors associated with prevalent TB among patients receiving HAART. Subjects and Methods: We conducted a cross-sectional study of adult patients who had received HAART for ≥12 weeks in a Nigerian tertiary hospital. Patients whose TB diagnosis predated HAART were excluded from the study. Pre-HAART data were collected from the clinic records, whereas post-HAART data were obtained through medical history, physical examination, and laboratory investigations. Standard TB screening/diagnostic algorithms as applicable in Nigeria were used. Logistic regression analysis was used to determine factors independently associated with prevalent TB. Results: about 65.8% (222/339) were women. The mean age was 41.1 (10.0) years and 23.6% (73/339) had past history of TB. The prevalence of active TB was 7.7% (26/339). Among these patients, 42.3% (11/26) had pulmonary TB, 34.6% (9/26) had disseminated TB, whereas 23.1% (6/26) had only extra-pulmonary disease. Only 45% (9/20) of patients with pulmonary involvement had positive sputum smear. Factors independently associated with prevalent TB were lower social class (adjusted odds ratio [aOR]: 31.7; 95% confidence interval [CI]: 1.1–1417.3), HAART non-adherence (aOR125.5; 95% CI: 9.6–1636.3), baseline CD4 <200cells/μl (aOR31.0; 95%CI: 1.6–590.6), previous TB (aOR13.8; 95% CI: 2.0–94.1), and current hemoglobin <10 g/dl (aOR10.3; 95% CI: 1.1–99.2). Conclusion: Factors associated with prevalent TB were a lower social class, HAART non-adherence, severe immunosuppression before HAART initiation, previous TB, and anemia post-HAART. TB case finding should be intensified in these high-risk groups. PMID:27213096

    Introduction The aim of the study was to evaluate whether subject positioning would affect the measurement of raw body volume, thoracic gas volume, corrected body volume and the resulting percent body fat as assessed by air displacement plethysmography (ADP). Methods Twenty-five young adult men (20.7±1.1y, BMI = 22.5±1.4 kg/m2) were measured using the BOD POD® system using a measured thoracic gas volume sitting in a ‘forward bent’ position and sitting up in a straight position in random order. Results Raw body volume was 58±124 ml (p<0.05) higher in the ‘straight’ position compared to the ‘bent’ position. The mean difference in measured thoracic gas volume (bent-straight = −71±211 ml) was not statistically significant. Corrected body volume and percent body fat in the bent position consequently were on average 86±122 ml (p<0.05) and 0.5±0.7% (p<0.05) lower than in the straight position respectively. Conclusion Although the differences reached statistical significance, absolute differences are rather small. Subject positioning should be viewed as a factor that may contribute to between-test variability and hence contribute to (in)precision in detecting small individual changes in body composition, rather than a potential source of systematic bias. It therefore may be advisable to pay attention to standardizing subject positioning when tracking small changes in PF are of interest.The cause of the differences is shown not to be related to changes in the volume of isothermal air in the lungs. It is hypothesized and calculated that the observed direction and magnitude of these differences may arise from the surface area artifact which does not take into account that a subject in the bent position exposes more skin to the air in the device therefore potentially creating a larger underestimation of the actual body volume due to the isothermal effect of air close to the skin.

    2010-01-01

    Background Hypertension is a common non communicable condition worldwide. In developing countries (including Nigeria), the use of complementary and alternative medicine (CAM) is common. This study investigated the frequency and factors associated with use of CAM among hypertensive subjects in an urban Nigerian community. Perspectives about the management of hypertension were obtained from CAM practitioners in the community. Methods Four hundred and forty hypertensive subjects in Idikan community, Ibadan, were interviewed using a semi-structured survey instrument. Association between categorical variables was tested using the chi-square test. Logistic regression analysis was done to identify independent predictor variables of CAM use, with CAM use as the outcome variable and the demographic and belief items as predictor variables. In-depth interviews were conducted with all known CAM practitioners in the community on issues relating to their beliefs, knowledge, practice and experiences in managing patients with hypertension in the community. Results In the study sample, 29% used CAM in the management of their hypertension. Among those using CAM, the most common forms used were herbs (63%) and garlic (21%). Logistic regression analysis revealed that four variables were independent predictors of CAM use: being male (OR 2.58, p < 0.0001), belief in supernatural causes of hypertension (OR 2.11, p = 0.012), lack of belief that hypertension is preventable (OR 0.57, p = 0.014) and having a family history of hypertension (OR1.78, p = 0.042). Other factors such as age, educational level and occupation were not independent predictors of CAM use. Interviews with CAM practitioners revealed that they believed hypertension was caused by evil forces, stress or "too much blood in the body". They also thought they could cure hypertension but that reduced costs (compared to hospitals) was one of the reasons most of their clients consult them. Conclusions The use of CAM is common

    The composition of the human gut microbiota is related to host health, and it is thought that dietary habits may play a role in shaping this composition. Here, we examined the population size and prevalence of six predominant bacterial genera and the species compositions of genus Bifidobacterium (g-Bifid) and Bacteroides fragilis group (g-Bfra) in 42 healthy Belgian adults by quantitative PCR (qPCR) over a period of one month. The population sizes and prevalence of these bacteria were basically stable throughout the study period. The predominant g-Bifid species were Bifidobacterium adolescentis and Bifidobacterium longum ss. longum, and the predominant g-Bfra species were Bacteroides vulgatus, Bacteroides uniformis, and Bacteroides ovatus. The Belgian gut microbiota data were then compared with gut microbiota data from 46 Japanese subjects collected according to the same protocol (Matsuki et al., Appl. Environ. Microbiol. 70, 167-173, 2004). The population size and prevalence of Bifidobacterium catenulatum group were significantly lower in the Belgian gut microbiota than in the Japanese gut microbiota (P < 0.001); however, the population size and prevalence of g-Bifid did not differ. This species-level qPCR analysis will be helpful for investigating the diversity of gut microbiota among ethnic groups.

    The present study examines the psychological characteristics and self-reported responses to xenobiotic agents such as tobacco smoke and pesticide of normal young adults with personality traits similar to those claimed for Parkinsonian patients. Previous research, though controversial, has suggested that persons with idiopathic Parkinson's disease (PD) have premorbid personality traits that may include shyness and repressive defensiveness. Other epidemiological evidence indicates that PD patients may have premorbidly increased prevalence of anxiety, affective, and/or somatoform disorders; decreased rates of smoking and alcohol consumption; and elevated exposure to herbicides or pesticides. A total of 783 college students enrolled in an introductory psychology course completed the Cheek-Buss Scale (shyness), the Marlowe-Crowne Social Desirability Scale (defensiveness), Symptom Checklist 90 (revised), the Mastery Scale, a health history checklist, and rating scales for frequency of illness from alcohol and 10 common environmental chemicals. Subjects were divided into four groups on the basis of above- versus below-median scores on the Cheek-Buss and Marlowe-Crowne scales (persons high in shyness and defensiveness, those high only in shyness, those high only in defensiveness, and those low in both shyness and defensiveness). The group high in shyness but low in defensiveness had the highest, whereas the group low in shyness but high in defensiveness had the lowest, total scores on the SCL-90-R; the two shyest groups were lowest in sense of mastery.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8021635

    The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of

    In Nigeria, just like in many other parts of the world, one of the most extensively discussed issues on the public agenda today is the increase in prison population. The aims of imprisonment are protection, retribution, deterrence, reformation and vindication. Investigations revealed that the prison services have been,neglected more than any other criminal justice agency in Nigeria. For example, most of the prisons were built during the colonial era for the purpose of accommodating a small number of inmates. Human Rights are the basic guarantees for human beings to be able to achieve happiness and self-respect; consequently, in most jurisdictions, the Human Rights Act confirms that these Rights do not stop at the prison gates. However, most States fail to meet the Human Rights obligations of their prisoners. As regards to health, for example, every prison should have proper health facilities and medical staff to provide dental and psychiatric care among others. This article discusses the Nigerian Prison System and challenges, trends and the related Human Rights and Ethical issues in Nigerian prisons. Some of the unmet needs of Nigerian prisoners which include, inter alia, living in unwholesome cells, delayed trial of inmates, lack of voting rights, access to information, lack of conjugal facilities for married prisoners, poor and inadequate nutrition, poor medical care, torture, inhumane treatment and the need to protect prisoners in a changing world. The present report has policy implications for reforming prison services in Nigeria, and countries that sing from the same song sheet with Nigeria on prison services, to conform to the Fundamental Human Rights of prisoners in the 21St century.

    Ethnopharmacological significance Nigerian herbalists possess indigenous ethnomedicinal recipes for the management of tuberculosis and related ailments. Aim of the study To carry out a collaborative preliminary modern scientific evaluation of the efficacy of some Nigerian ethnomedicines used by traditional medicine practitioners (TMPs) in the management of tuberculosis and related ailments Materials and methods Ethnomedicinal recipes (ETMs) were collected from TMPs from locations in various ecological zones of Nigeria under a collaborative understanding. The aqueous methanolic extracts of the ETMs were screened against Mycobacterium bovis, BCG and Mycobacterium tuberculosis (M. tb.) strain H37Rv using the broth microdilution method. Results Extracts of ETMs screened against BCG showed 69% activity against the organism. The activities varied from weak, ≤ 2500μg /mL to highly active, 33μg /mL 64% of the extracts were active against M. tb. The activities of the extracts against M.tb. varied from weak, ≤ 2500μg /mL to highly active, 128μg/mL. There was 77% agreement in results obtained using BCG or M. tb. as test organisms Conclusion The results show clear evidence for the efficacy of the majority of indigenous Nigerian herbal recipes in the ethnomedicinal management of tuberculosis and related ailments. BCG may be effectively used, to a great extent, as the organism for screening for potential anti-M. tb. agents. A set of prioritization criteria for the selection of plants for initial further studies for the purpose of antituberculsis drug discovery research is proposed. PMID:24911338

    Objective Obesity is a prevalent condition in industrialized societies and is increasing around the world. We sought to assess the relative importance of resting energy expenditure (REE) and activity energy expenditure (AEE) in two populations with different rates of obesity. Methods Women of African descent between 18 and 60 were recruited from rural Nigeria and from metropolitan Chicago. Total energy expenditure (TEE) was measured using the doubly labeled water technique and REE by indirect calorimetry; AEE was calculated as the difference between TEE and the sum of REE plus a factor for the thermic effect of food. In the analyses all EE parameters were adjusted for body size using a regression method. Comparisons were made between the groups and associations between EE and adiposity examined. Results A total of 149 Nigerian and 172 African-American women completed the protocol. All body size measurements were lower in the Nigerian women. Adjusted TEE and REE were higher in the Nigerian cohort but adjusted AEE did not differ significantly. Adjustment for parity, seasonality and recent illness did not modify mean AEE or adiposity. In neither cohort was there a meaningful association between measures of AEE and adiposity. Conclusion In these cohorts of women from very different environments, AEE did not differ significantly nor was it associated cross-sectionally with adiposity. If generalizable, these findings suggest that reduction in AEE may have less of a role in the development of obesity than anticipated. The possibility remains that variation in type and duration of activity plays a role not captured by total AEE. PMID:19186335

    In Nigeria, just like in many other parts of the world, one of the most extensively discussed issues on the public agenda today is the increase in prison population. The aims of imprisonment are protection, retribution, deterrence, reformation and vindication. Investigations revealed that the prison services have been,neglected more than any other criminal justice agency in Nigeria. For example, most of the prisons were built during the colonial era for the purpose of accommodating a small number of inmates. Human Rights are the basic guarantees for human beings to be able to achieve happiness and self-respect; consequently, in most jurisdictions, the Human Rights Act confirms that these Rights do not stop at the prison gates. However, most States fail to meet the Human Rights obligations of their prisoners. As regards to health, for example, every prison should have proper health facilities and medical staff to provide dental and psychiatric care among others. This article discusses the Nigerian Prison System and challenges, trends and the related Human Rights and Ethical issues in Nigerian prisons. Some of the unmet needs of Nigerian prisoners which include, inter alia, living in unwholesome cells, delayed trial of inmates, lack of voting rights, access to information, lack of conjugal facilities for married prisoners, poor and inadequate nutrition, poor medical care, torture, inhumane treatment and the need to protect prisoners in a changing world. The present report has policy implications for reforming prison services in Nigeria, and countries that sing from the same song sheet with Nigeria on prison services, to conform to the Fundamental Human Rights of prisoners in the 21St century.

    The purpose of this study was to assess differences between Nigerian junior and senior preservice teachers' science teaching efficacy beliefs. Data in this study were collected from a total number of 221 preservice teachers enrolled in junior and senior secondary science teacher education programs in Nigeria using Science Teaching Efficacy Belief Instrument (STEB-B) (Enoch and Riggs in Sci Educ 74:625-638 1990). Results indicated that junior secondary preservice teachers were as efficacious as their senior secondary preservice teachers on the two dimensions of STEB-B. In addition, analyses did not reveal any significant gender differences on the two dimensions of STEB-B.

    The present study assessed the growth problems in an indigenous African population of Nigerian urban public school children. The study population consisted of 1390 Nigerian children (predominantly Igbo), 718 boys and 672 girls, ages 4-10 years. Compared to the National Center for Health Statistics (NCHS) reference population, the Nigerian children had an excess prevalence of both short stature and underweight. The prevalence of short stature was 14.2% for the boys and 17.4% for the girls. Approximately 20% of the children were underweight whereas less than 1% were considered overweight. These data demonstrate an excess of both acute and chronic malnutrition relative to the NCHS reference population.

    This study set out to investigate the pressures experienced by different individuals to drink, or drink a little more than intended, by someone who drinks or drinks more than they do. A total of 2099 Nigerian adults between the ages of 18 and 65 years were randomly sampled. The frequency with which they experienced such other drinkers encouraging them to drink or drink more than intended from various sources was examined. Logistic regression was used to identify significant individual predictors of receiving pressure by sources of influence. Focus group discussions were also held to examine how these pressures are applied in various settings. Results indicated that male friends or acquaintances were the sources respondents reported influenced them the most to drink or drink more. Significant predictors of pressure varied by source but tended to include religion (5 of 6 sources) and gender (3 of 6). Results showed that pressure to drink or drink a little more was seen to come more from males than from females. It raises the need to have a better knowledge of these factors, particularly as they may relate to heavy or problematic drinking, and their implications for prevention and treatment. PMID:20651928

    Exposure to Nigerian bonny light crude oil (BLCO) in the southern part of Nigeria has been reported to be associated with reproductive toxicity, but there is paucity of information on its interference with steroidogenesis. This study investigated the influence of BLCO on testicular steroidogenesis and plasma levels of hormones from the pituitary and thyroid components of the brain-pituitary-testicular axis. Adult male Wistar rats were orally treated with BLCO dissolved in corn oil at 0, 200 and 800 mg/kg for 7 days. Immunoblot analysis revealed that BLCO exposure suppressed steroid acute regulatory protein and androgen-binding protein expression with concomitant decrease in 3β-hydroxysteroid dehydrogenase (HSD) and 17β-hydroxysteroid dehydrogenase activities. BLCO exposure significantly decreased plasma concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin and intratesticular testosterone, but elevated thyrotropin, triiodothyronine and thyroxine above the control values. The data presented herein indicate that undue exposure to BLCO has an inhibitory effect on testicular steroidogenesis. The underlying mechanisms for BLCO-induced testicular dysfunction may involve its disruptive effect on the brain-pituitary-testicular axis. These observations highlight the potential risk to public health for a population where, unfortunately, oil spillages occur frequently. PMID:24171665

    Using genome-wide genotypes, we characterized the genetic structure of 103,006 participants in the Kaiser Permanente Northern California multi-ethnic Genetic Epidemiology Research on Adult Health and Aging Cohort and analyzed the relationship to self-reported race/ethnicity. Participants endorsed any of 23 race/ethnicity/nationality categories, which were collapsed into seven major race/ethnicity groups. By self-report the cohort is 80.8% white and 19.2% minority; 93.8% endorsed a single race/ethnicity group, while 6.2% endorsed two or more. Principal component (PC) and admixture analyses were generally consistent with prior studies. Approximately 17% of subjects had genetic ancestry from more than one continent, and 12% were genetically admixed, considering only nonadjacent geographical origins. Self-reported whites were spread on a continuum along the first two PCs, indicating extensive mixing among European nationalities. Self-identified East Asian nationalities correlated with genetic clustering, consistent with extensive endogamy. Individuals of mixed East Asian-European genetic ancestry were easily identified; we also observed a modest amount of European genetic ancestry in individuals self-identified as Filipinos. Self-reported African Americans and Latinos showed extensive European and African genetic ancestry, and Native American genetic ancestry for the latter. Among 3741 genetically identified parent-child pairs, 93% were concordant for self-reported race/ethnicity; among 2018 genetically identified full-sib pairs, 96% were concordant; the lower rate for parent-child pairs was largely due to intermarriage. The parent-child pairs revealed a trend toward increasing exogamy over time; the presence in the cohort of individuals endorsing multiple race/ethnicity categories creates interesting challenges and future opportunities for genetic epidemiologic studies.

    The Kaiser Permanente Research Program on Genes, Environment, and Health (RPGEH) Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort includes DNA specimens extracted from saliva samples of 110,266 individuals. Because of its relationship to aging, telomere length measurement was considered an important biomarker to develop on these subjects. To assay relative telomere length (TL) on this large cohort over a short time period, we created a novel high throughput robotic system for TL analysis and informatics. Samples were run in triplicate, along with control samples, in a randomized design. As part of quality control, we determined the within-sample variability and employed thresholds for the elimination of outlying measurements. Of 106,902 samples assayed, 105,539 (98.7%) passed all quality control (QC) measures. As expected, TL in general showed a decline with age and a sex difference. While telomeres showed a negative correlation with age up to 75 years, in those older than 75 years, age positively correlated with longer telomeres, indicative of an association of longer telomeres with more years of survival in those older than 75. Furthermore, while females in general had longer telomeres than males, this difference was significant only for those older than age 50. An additional novel finding was that the variance of TL between individuals increased with age. This study establishes reliable assay and analysis methodologies for measurement of TL in large, population-based human studies. The GERA cohort represents the largest currently available such resource, linked to comprehensive electronic health and genotype data for analysis. PMID:26092717

    The Kaiser Permanente (KP) Research Program on Genes, Environment and Health (RPGEH), in collaboration with the University of California—San Francisco, undertook genome-wide genotyping of >100,000 subjects that constitute the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort. The project, which generated >70 billion genotypes, represents the first large-scale use of the Affymetrix Axiom Genotyping Solution. Because genotyping took place over a short 14-month period, creating a near-real-time analysis pipeline for experimental assay quality control and final optimized analyses was critical. Because of the multi-ethnic nature of the cohort, four different ethnic-specific arrays were employed to enhance genome-wide coverage. All assays were performed on DNA extracted from saliva samples. To improve sample call rates and significantly increase genotype concordance, we partitioned the cohort into disjoint packages of plates with similar assay contexts. Using strict QC criteria, the overall genotyping success rate was 103,067 of 109,837 samples assayed (93.8%), with a range of 92.1–95.4% for the four different arrays. Similarly, the SNP genotyping success rate ranged from 98.1 to 99.4% across the four arrays, the variation depending mostly on how many SNPs were included as single copy vs. double copy on a particular array. The high quality and large scale of genotype data created on this cohort, in conjunction with comprehensive longitudinal data from the KP electronic health records of participants, will enable a broad range of highly powered genome-wide association studies on a diversity of traits and conditions.

    Trace elements are accepted to be involved directly or indirectly in the process of cancer formation. In this study, serum selenium, copper and zinc were measured in three groups of patients using atomic absorption spectrometer. A total of 29 Nigerian women were included: group I consisted of nine age-matched healthy controls without breast problems; group 2 included nine women with benign breast disease; and group 3 was comprised of women with breast cancer. The serum concentration of copper (Cu) was significantly higher in patients with cancer when compared to the control group (1.43 +/- 0.31 microg/ml vs 0.91 +/- 0.18 microg/ul/0.94 +/- 0.10 microg/ml). The zinc (Zn) concentration was significantly lower in the breast cancer group than in the other two groups (0.74 +/- 0.21 microg/ml vs 1.14 +/- 0.31 ug/ml/1.11 +/- 0.29 microg/ml; p < 0.05). The study shows alteration in the concentration of copper and zinc in serum of patients with breast cancer, which may indicate abnormal copper and zinc metabolism in Nigerian females with breast cancer.

  4. Stem cells in Dentistry: knowledge and attitude of Nigerian Dentists

    Background Several controversies exist about the methods of harvesting and eventual utilization of stem cells in Medicine and Dentistry. The objective of the study was to investigate the awareness, attitude and knowledge of the use of stem cells in Dentistry among Nigerian Dentists. Methods This descriptive, cross-sectional study was conducted among dentists selected from both private and public health sectors, in some of the major cities in Nigeria. Results The majority of the participants were ≤35 years in age, male, Pentecostal Christians, possessed a postgraduate qualification, had practiced for ≤5 years and were specialists or specializing. In this study, 153(81.0%) of the participants reported awareness about the use of stem cells in dentistry which was significantly associated with qualification and type of practice. Most of the respondents 114 (60.3%) had a poor knowledge of the use of stem cells in Dentistry. This was significantly associated with type of practice and awareness about stem cell use in dentistry but binary logistic regression showed awareness as the only determinant of knowledge. About three-quarters 142 (75.1%) of the participants exhibited positive attitude towards stem cell use. This had a positive non-significant association with knowledge and reported awareness. Conclusion Data from this study revealed a high level of awareness, positive attitude to and poor knowledge of the use of stem cells in Dentistry among a cross section of Nigerian Dentists.

    Significant asymptomatic bacteriuria is a risk factor for symptomatic urinary infection and septicemia among predisposed individuals such as diabetics. We investigated the pattern of asymptomatic bacteriuria among our type 2 diabetics with a view to documenting the prevalence, type of organisms responsible and the antibiotic susceptibility pattern. One hundred and twenty-four type 2 Nigerian diabetics (55 males and 69 females) submitted midstream urine specimens for culture. Thirty-three patients had significant bacteriuria (9 males and 24 females), showing the frequency of occurrence of asymptomatic bacteriuria to be 26.6%. The most common organism isolated was Klebsiella pneumonia at 42.4%. Gram-negative bacilli made up about 23 (69.7%) of the isolates. Isolates were poorly sensitive to the readily available antibiotics (ampicillin, tetracycline and cotrimoxazole), but a large number of the organisms isolated were sensitive to nitrofurantoin, gentamicin, ciprofloxacin and ofloxacin. Sensitivity to erythromycin, nalidixic acid and cefuroxime was moderate. Asymptomatic bacteriuria is, thus, more prevalent among the Nigerian diabetic population than in the non-diabetics. A changing pattern of disease is observed with Klebsiella sp. now accounting for the majority of asymptomatic bacteriuria among diabetics. The organisms are not sensitive to the commonly available antibacterial agents. PMID:12793791

    Brown beans are the preferred varieties over the white beans in Nigeria due to their assumed richer nutrients. This study was aimed at assessing and characterising some popular Nigerian common beans for their nutritive value based on seed coat colour. Three varieties, each, of Nigerian brown and white beans, and one, each, of French bean and soybean were analysed for 19 nutrients. Z-statistics test showed that Nigerian beans are nutritionally analogous to French bean and soybean. Analysis of variance showed that seed coat colour varied with proximate nutrients, Ca, Fe, and Vit C. Chemometric analysis methods revealed superior beans for macro and micro nutrients and presented clearer groupings among the beans for seed coat colour. The study estimated a moderate genetic distance (GD) that will facilitate transfer of useful genes and intercrossing among the beans. It also offers an opportunity to integrate French bean and soybean into genetic improvement programs in Nigerian common beans.

    Introduction: The aims of this study were to establish the prevalence of dental features that indicate a need for early intervention and to ascertain the prevalence of different methods of early treatment among a population of Nigerian children in mixed dentition. Methods: Occlusal relationships were evaluated in 101 children in mixed dentition between the ages of 6 and 12 years who presented at the Orthodontic Unit, Department of Child Dental Health, Lagos University Teaching Hospital over a 2 years period. The need for different modes of early orthodontic treatment was also recorded. Results: Anterior tooth rotations (61.4%) and increased overjet (44.6%) were the most prevalent occlusal anomalies. Others included deep bite (31.7%), reverse overjet (13.9%), and anterior open bite (14.8%). Severe maxillary spacing and crowding were exhibited in 12.0% and 5.0%, respectively. About a third (35.7%) of the subjects presented with crossbite while lip incompetence was observed in 43.6% of the subjects. About 44% of the subjects also presented with various oral habits with digit (15.8%) and lip sucking (9.9%) being the most prevalent. Subjects were recommended for treatment with 2 by 4 fixed orthodontic appliances (22.3%), habit breakers (20.7%), removable orthodontic appliances (16.5%), and extractions (15.7%). Conclusions: Increased overjet and anterior tooth rotation were the majority of occlusal anomalies seen, which are not only esthetically displeasing but may also cause an increased susceptibility to trauma to these teeth. Treatment options varied from extractions only to the use of appliance therapy. PMID:27556019

    The average activity concentrations of seven locally produced food commodities that form the total diets of a baby, a teenager or an adult male in Nigeria were measured by means of a well-calibrated high-resolution lithium-drifted germanium (Ge(Li)) spectrometer system. The food commodities were collected at several centers such as a nuclear research center as well as metropolitan and industrial areas. The emission lines identified with reliable regularity belonged to the 238U and 232Th decay series. The other isotope is a non-related naturally occurring radionuclide, 40K. Average total specific-activity values of 7.29 ± 1.08, 6.27 ± 1.01 and 11.23 ± 1.64 Bq/kg for 238U, 232Th and 40K, respectively, were obtained for the seven food commodities studied. The food samples were also checked for fission-product residues ( 137Cs and 90Sr) from atmospheric weapons tests which are slowly being purged from the food chain. Their estimation revealed that they were below the minimum detectable limit determined at a two-standard deviation analytical error.

    2013-01-01

    Background Small-for-gestational age (SGA) newborns constitute a special group of neonates who may have suffered varying degrees of intrauterine insults and deprivation. Variations in birth weight, length and Ponderal Index (PI) depend on the type and degree of intrauterine insults the babies were exposed to. The objective of the study was to determine the current prevalence of term SGA births in a Nigerian Tertiary Hospital and the current pattern of Ponderal Indices among term SGA in a population of Nigerian babies. Methods Subjects comprised of consecutive term singleton mother-baby pairs in the first 24 hours of life. It was a cross sectional study. The anthropometric parameters of each baby were recorded and the PI was also determined. Results Out of 1,052 live births during the study period (September to December, 2009), 825 were term, singleton babies. Five hundred and eight-one babies (70.4%) fall into the upper socio-economic classes 1 and II, 193 (23.4%) in the middle class and 51 (6.2%) were of the lower classes IV and V. None of the mothers indicated ingestion of alcohol or smoking of cigarette. Fifty-nine babies (7.2%) were small-for gestational age (SGA). Of the 59 SGA subjects, 26 (44.1%) were symmetrical SGA while 33 (55.9%) were asymmetrical SGA. There was no significant sex or socioeconomic predilection for either symmetrical or asymmetrical growth (p = 0.59, 0.73 respectively). Conclusion The findings showed that proportionality in SGA fetuses is a continuum, with the PI depending on the duration of intrauterine insult and the extent of its effects on weight and length before delivery.

    Breast cancer incidence in Nigerian women has significantly increased during the past three decades in parallel with the rapid industrialization of that country. This suggested that the associated widespread contamination of the soil and of the water supplies by lead (Pb) and other industrial metals was a major contributing cause. Because of its many domestic, industrial, and automotive uses, Pb is of particular concern as it has been shown to promote the development of mammary tumors in murine mammary tumor virus-infected female C3H mice at levels as low of 0.5 ppm Pb in the drinking water. Lead belongs to the group of selenium-antagonistic elements that interact with selenium (Se), abolishing its anti-carcinogenic effect. Lead on chronic, low-level exposure in addition also accelerates tumor growth rates. Higher levels of Pb were found in blood and head hair samples of newly diagnosed patients with breast cancer, all with infiltrating ductal carcinoma, the most common form of breast cancer in Nigeria, seen at Obafemi Awolowo University, than in cancer-free controls from the same area. Evidence for interactions between Pb and Se was obtained from blood, hair, and tumor biopsy tissue analyses. Furthermore, the Pb levels in hair samples of the patients were directly correlated with the volumes of their tumors, in accord with the tumor growth-promoting effects of Pb. Conversely, Se levels in hair and blood were inversely correlated with the tumor volumes, consistent with the anti-proliferative effects of Se. Several other elements, e.g., Cd, Hg, Cr, Sn, and As, were detected in the scalp hair of the patients and the controls, although at significantly lower levels than those of Pb. However, correlation calculations revealed them also to interact with Se, suggesting that only a fraction of the Se in organs and tissues is actually present in bioactive forms. In metal-exposed subjects, a state of latent Se deficiency may exist, resulting in depressed immune functions

    Introduction Community based interventions have long been linked to tuberculosis control efforts. Effectively treated and cured patients living within their home communities are often the best advocates and may become the drivers of social mobilization to support control of tuberculosis. Methods A descriptive cross-sectional knowledge, attitude, behavioral and practice (KABP) survey on tuberculosis was carried out in a rural Nigerian community. We used the multi-stage sampling method for subject selection. We administered an interview schedule consisting of a pre-tested structured interviewer-administered questionnaire, together with in-depth interviews and focus group discussions. Results We applied the questionnaire to 1186 people in designated rural households. Most of the participants, (1154, 97.3%) had prior knowledge and awareness about tuberculosis as a disease, 612 (51.6%) considered tuberculosis a result of HIV/AIDS epidemics or malnutrition, and 451 (38%) believed that it can be cured by Western medicine. The unwillingness of respondents to relate with TB patients was generally high (97%, 1150), even where levels of awareness and knowledge were high. Conclusion These results should be used to orient tuberculosis control programs, especially those aimed at mobilizing people for tuberculosis control and eradication. PMID:24432287

    We investigated the effect of concurrent ingestion of Garcinia kola seed on the pharmacokinetics of quinine. In a randomized crossover study, 24 healthy Nigerian volunteers were assigned into two groups (A and B; n = 12 per group) on the basis of G. kola dose orally ingested. Each subject received 600mg quinine sulphate before and after ingesting 12.5g of G. kola once daily for seven days (Group A) or 12.5g twice daily for six days and once on the seventh day (Group B). Blood samples were collected and analyzed for plasma quinine and its metabolite, (3-hydroxyquinine) using a validated HPLC method. Concurrent administration of quinine with G. kola reduced quinine tmax by 48% (group A), mean Cmax by 19% and 26% in groups A and B, and slight reduction in mean AUC0–∞ of quinine in both groups. 3-hydroxyquinine Cmax also reduced by 29% and 32%; AUC0–∞ by 13% and 9% respectively. The point estimates of the T/R ratio of the geometric means for all Cmax obtained and only the AUC0–∞ at a higher dose of G. kola were outside the 80–125% bioequivalence range. In conclusion, an herb-drug interaction was noted with concurrent quinine and G. kola administration. PMID:25328082

    Background In various people of the Western world, gastro-oesophageal reflux (GOR) has been reported to be a common problem. Various studies have also assessed the relationship between GOR and dental erosion. The authors are not aware of such studies in Nigerians. It is therefore the aims of the present study to estimate the prevalence of GOR; to estimate the prevalence of dental erosion in patients with GORD; to document the oral findings in patients diagnosed with GORD and to compare these findings with previous studies elsewhere. Methods A total of 225 subjects comprising of 100 volunteers and 125 patients diagnosed with GORD were involved in this study. History of gastric juice regurgitation and heartburn were recorded. Oral examination to quantify loss of tooth structure was done using the tooth wear index (TWI) designed by Smith and Knight (1984). Results Twenty patients with GORD presented with dental erosion in the maxillary anterior teeth with TWI scores ranging from 1–3. The prevalence of erosion was found to be statistically significant between GORD patients (16%) and control (5%) (p < 0.05), but not significant between endoscopic diagnostic groups (p > 0.05). Conclusion The present study supports the consideration of dental erosion as the extra-oesophageal manifestation of GORD. However the association between GORD and burning mouth sensation needs more investigation. PMID:15740613

    Objectives This study examined the perceptions of cigarette packaging and the potential impact of plain packaging regulations. The hypothesis was that the branded cigarette packages would be rated more positively than the corresponding plain packs with and without descriptors. Design Between-subjects experimental online survey. Male and female participants were separately randomised to one of the three experimental conditions: fully branded cigarette packs, plain packs with descriptors and plain packs without descriptors; participants were asked to evaluate 12 individual cigarette packages. The participants were also asked to compare five pairs of packs from the same brand family. Setting Norway. Participants 1010 youths and adults aged 15–22. Primary outcome measures Ratings of appeal, taste and harmfulness for individual packages. Ratings of taste, harm, quality, ‘would rather try’ and ‘easier to quit’ for pairs of packages. Results Plain with and without descriptors packs were rated less positively than the branded packs on appeal (index score 1.63/1.61 vs 2.42, p<0.001), taste (index score 1.21/1.12 vs 1.70, p<0.001) and as less harmful (index score 1.0.34/0.36 vs 0.82, p<0.001) among females. Among males, the difference between the plain with and without descriptors versus branded condition was significant for appeal (index score 2.08/1.92 vs 2.58, p<0.005) and between the plain without descriptors versus branded condition for taste (index score 1.18 vs 1.70, p<0.00). The pack comparison task showed that the packs with descriptors suggesting a lower content of harmful substances, together with lighter colours, were more positively rated in the branded compared with the plain condition on dimensions less harmful (β −0.77, 95% CI −0.97 to −0.56), would rather try (β −0.32, 95% CI −0.50 to −0.14) and easier to quit (β −0.58, 95% CI −0.76 to −0.39). Conclusions The results indicate that a shift from branded to plain cigarette

    This study contrasts body compositions (by six methods) of eight cystic fibrosis (CF) subjects with those of eight control subjects matched for age, height, and sex. CF subjects weighed 84% as much as control subjects. Densitometry and two bioelectrical impedance-analysis methods suggested that reduced CF weights were due to less lean tissue (10.7, 9.5, and 10.4 kg). Total-body electrical conductivity (TOBEC) and skinfold-thickness measurements indicated that CF subjects were leaner than control subjects and had less fat (5.4 and 3.6 kg) and less lean (5.2 and 7 kg) tissue. D2O dilution showed a pattern similar to TOBEC (8.3 kg less lean, 2.7 kg less fat tissue). Densitometry estimates of fat (mass and percent) were not correlated (r less than 0.74, p greater than 0.05) with any other method for CF subjects but were correlated with all other methods for control subjects. CF subjects contained less fat and lean tissue than did control subjects. Densitometry by underwater weighing is unsuitable for assessing body composition of CF patients.

    One hundred and twenty-six Nigerian cases of epithelial jaw cysts were retrieved from case notes and biopsy records of the Department of Oral and Maxillofacial Surgery and Department of Oral Pathology and Oral Biology of the Lagos University Teaching Hospital. The cases were analysed for age, sex, site and methods of management. Results show that developmental odontogenic cysts (57.14%) were more common than inflammatory odontogenic cysts (26.94%). Dentigerous cyst (22.22%) was the most common epithelial jaw cyst, followed by radicular cyst (21.43%). Developmental non-odontogenic cysts were more than twice as common in females as in males. Sixty-eight per cent of epithelial jaw cysts were treated by enucleation, 10% by marsupialisation, 13% by jaw resection and 9% by surgical excision.

    Prevalence of helminth parasites was carried out in both male and female villagers graded into three age groups (5-14 years, 15-25 years, 26-55 years). Children between 5 and 14 years of age had the highest prevalence of Ascaris, Schistosoma haematobium and Trichuris while the villagers between 26-55 years of age had lowest prevalence of these parasites. However, hookworms were highly common among the villagers aged between 26 and 55 years and least common among the school children aged between 5 and 14 years. Female children between the ages of 5 and 14 years and males of the same age group were highly infested with Ascaris and Trichuris. This finding in a Nigerian village suggested that helminth infestation is age and sex dependent which is therefore a factor of the frequency in host-parasite contact determined by mode of life of the parasites and the hosts.

    Alpha-1-antitryspin (x-1-AT) may play a possible role as effector of immunological stasis. This study examines the levels of this glycoprotein in 73 breast milk samples from 60 healthy Nigerian mothers. Levels of x-1-AT were measured by single radial immunodiffusion according to the method of Mancini. Serum protein was measured by Lowry's method, albumin by Doumas' method. Highest mean levels of x-1-AT were found in colostrum (25 mg/dl). The level was significantly higher compared to transitional milk (14.2 mg/dl) or mature milk (165 mg/dl) (p0.001). Breast milk contains substantial amounts of x-1-AT which is not destroyed by pasturization at 56 degrees Centigrade. The immunological protective properties of breast milk are ideal for newborn babies, particularly those who are low birthweight and are thus most susceptible to neonatal necrotizing enterocolitis.

    Methanolic (MEOH), evaporated crude water (ECW) and unevaporated crude water (UECW) extracts of 25 Nigerian plants, used for different medicinal and domestic purposes were screened for molluscacidal activity on laboratory-reared Lymnaea natalensis Krauss. Seven of the plants were not active; extracts from 18 (72 per cent) of the plants, some of which are renowned fish poisons, had molluscicidal activity. These were Acacia nilotica, Aristolochia albida, Balanites aegyptiaca, Blighia sapida, Boswellia dalzielii, Detarium microcarpum, Gnidia kraussiana, Kigelia africana, Nauclea latifolia, Opilia celtidefolia, Parkia clappertoniana, Polygonum limbatum, Pseudocedrela kotschyi, Sclerocarya birrea, Securidaca longipedunculata, Ximenia americana, Vetiveria nigritana and Ziziphus abyssinica. The LC50 of these extracts were determined. It is strongly recommended that the toxic effects of these extracts against fish, cercariae, snail eggs and mammals be further investigated so as to determine the right concentration, especially for use in fish ponds.

    Human sera collected from Nigerians were examined for plaque reduction neutralizing and infection-enhancing antibodies against dengue 2, yellow fever, and West Nile viruses. Neutralization tests showed that 17 of 19 sera contained flavivirus neutralizing antibody; 11 were positive to all 3 viruses, 5 to dengue and yellow fever, and 1 to dengue virus only. Two sera had no detectable neutralizing antibody to any of the flaviviruses. Enhancement assays showed that 17 flavivirus neutralizing antibody-positive sera contained infection-enhancing antibodies to dengue 2, and 16 had antibody to yellow fever. Although 11 sera were positive for West Nile neutralizing antibody, 17 enhanced this virus. Heterologous infection-enhancing antibody titers were lower than the homologous ones. Broadly reacting sera and those with high neutralizing antibody titers produced the highest infection-enhancing antibody titers.

    Volunteers who consumed 88g alcohol/day (= 2.48L of lager beer) had elevated levels of systolic and mean arterial Blood Pressure. The association between consumption of locally brewed Nigerian lager beer with arterial hypertension was independent of age and weight. The true mechanism for the development of hypertension in these alcohol-users is at present not clear. All brands of lager beer investigated contain as much as five times the sodium content of potable water. It is desirable to evaluate the consequences of ingesting such quantities of sodium in lager beers. The effect of alcohol on other monovalent and divalent cations may shed some light onto the true mechanism for the pathogenesis of alcohol-induced hypertension. 15 references, 3 tables.

    Infants and children are at higher risk of heat stroke for several reasons. We report these cases to highlight the danger of leaving children unsupervised in vehicles, aid prompt diagnosis, and management of heat stroke. Two Nigerian siblings aged ranges 5 and 3 years old, were trapped inside an unlocked vehicle and subsequently developed heat stroke. Both children presented with hyperthermia, severe dehydration, convulsions, and loss of consciousness. One of them also had hematuria. They were treated by spraying water onto their bodies to bring down the temperature, intravenous fluid resuscitation, oxygen therapy, and anticonvulsants. Both eventually recovered and were discharged with no obvious neurologic sequalae, but are being followed-up. PMID:25511359

    Nigerian Coal Corporation started operations in 1916 and in October 1977 introduced full mechanization at its coal mine in Enugu. An appraisal of the mining accidents between 1975-1980 showed an overall downward trend following mechanization, from 1073 per 1000 in 1975 to 425 in 1980 (a 60% reduction). The underground accidents were reduced from a monthly average of 63 to 26 but those at the surface remained basically unaffected. Changes were also recorded in sickness absences indices, with the most significant occurring with respect to the severity index which dropped from 9.2 in 1975 to 3.0 in 1980. The distribution of injury remained essentially the same except that injuries to the upper limbs became more common than the more serious pelvic injury prior to mechanization. The impact of mechanization in industries in developing countries are discussed and ways of ensuring optimum benefits from this transfer of technology suggested.

    Human African trypanosomiasis is a neglected tropical disease with complex clinical presentation, diagnosis, and difficult treatment. The available drugs for the treatment of trypanosomiasis are old, expensive, and less effective, associated with severe adverse reactions and face the problem of drug resistance. This situation underlines the urgent need for the development of new, effective, cheap, and safe drugs for the treatment of trypanosomiasis. The search for new antitrypanosomal agents in this study is based on ethnomedicine. In vitro antitrypanosomal activity of 36 plant extracts from 10 plant species from Nigerian ethnomedicine was evaluated against bloodstream forms of Trypanosoma brucei rhodesiense STIB 900. Cytotoxic activity was determined against mammalian L6 cells. Alamar blue assay was used to measure the endpoint of both antitrypanosomal and toxicity assays. The ethyl acetate extract of leaves of Ocimum gratissimum Linn. (Labiatae) showed the highest antitrypanosomal activity (IC(50) of 2.08 ± 0.01 μg/ml) and a high selective index of 29. Furthermore, the hexane, ethyl acetate, or methanol extracts of Trema orientalis (L.) Blume (Ulmaceae), Pericopsis laxiflora (Benth. ex Baker) Meeuwen, Jatropha curcas Linn. (Euphorbiaceae), Terminalia catappa Linn. (Combretaceae), and Vitex doniana Sweet (Verbenaceae) displayed remarkable antitrypanosomal activity (IC(50) 2.1-17.2 μg/ml) with high selectivity indices (20-80) for trypanosomes. The antitrypanosomal activity of T. catappa and T. orientalis against T. brucei rhodesiense (STIB 900) is being reported for the first time in Nigerian ethnomedicine, and these plants could be a potential source of antitrypanosomal agents.

    The Nigerian economy had remarkable industrial growth between 1970 and 1980 and industrialization and urbanization have been sustained albeit at a slower rate. Nevertheless, waste management remains grossly underdeveloped. Environmental concern is only a recent phenomenon, resulting thus far in the launching of a monthly clean-up campaign in 1984 and the establishment of the Federal Environmental Protection Agency (FEPA) in 1988. The level of public awareness has not been encouraging. The indiscriminate discharge of largely untreated factory and urban effluents has continued. Streets and home surroundings become littered soon after clean-up exercises. Inadequate facilities contribute to the unwholesome situation. Refuse collecting centers are mostly without any holding containers, and solid wastes, the focus of the monthly clean-up, are left on the bare ground. Heavy automobile traffic and high lead content of the local automobile fuels have not helped matters. Heavy metals in the human environment are of global concern. In developed countries, limits of concentrations in fish and other foods have been set to safeguard public health, but Nigeria has yet to set any standards because of lack of baseline data. Within the last decade, scientists have been reporting on heavy metal levels in fish from the aquatic environment of Nigeria. Among the metals, lead was the most prominent, with a mean value comparable to the set limits in Great Britain and New Zealand. The present study was aimed at further establishing the levels of contamination in fish by lead and other metals in the Nigerian aquatic systems. Smoke-dried fish, being the most consumed by the local population, was chosen for the survey on the levels of cadmium, cobalt, copper, chromium, iron, manganese, lead and zinc. Possible surface contamination arising from observed poor handling practices was also investigated. 18 refs., 1 fig., 4 tabs.

    Objective Several publications have established a relationship between sperm DNA damage and male factor infertility, based on data from America, Europe, and Asia. This study aimed to compare the extent of sperm DNA damage in sperm samples from Nigerian men with unexplained infertility and in sperm samples from a fertile group composed of sperm donors who had successfully impregnated a female partner naturally or through assisted conception. Methods A total of 404 men underwent male fertility evaluation at Androcare Laboratories and Cryobank participated in this study. Semen analysis and a sperm chromatin structure assay (SCSA) were performed on all subjects. Results The men in the unexplained infertility group were slightly older than the men in the fertile sperm group (36±10 years vs. 32±6 years, p=0.051). No significant difference was observed between the two groups in semen analysis parameters (p≥0.05). Men in the unexplained infertility group with normal semen parameters had a significantly higher DNA fragmentation index (DFI) than men in the fertile sperm group (27.5%±7.0% vs. 14.1%±5.3%, p<0.05). In the unexplained infertility group, 63% of the men had a DFI greater than 20%, compared to 4% in the fertile sperm group. In the unexplained infertility group, 15.2% of the subjects had a DFI greater than 30%, compared to 1% in the fertile sperm group. Conclusion Our study showed that the SCSA may be a more reliable predictor of fertility potential than traditional semen analysis in cases of unexplained infertility. PMID:26473109

    2008-01-01

    The present study was designed to determine whether becoming a mother during the adolescent period changes maternal responsiveness or maternal motivation, assessed through hormonal, autonomic, and hedonic responses to recorded infant cries and interactions with their babies. Fifty-six teen mothers were compared to 58 teen non-mothers and 49 adult mothers. Teen mothers reported more sympathy and alertness in response to recorded infant cries compared to non -mother teens; however, among the teen women there were no differences between mothers and non-mothers in heart rate and cortisol responses to infant cries. In contrast, in comparison to adult mothers, teen mothers reported the same levels of sympathy and alertness to infant cries; however, adult mothers showed an 'alerted' pattern of heart rate and cortisol response to infant cries not seen in the teen mother group. Inclusion of the covariate, fathers' employment classification as an index of SES or time of testing and cortisol sampling did not affect this pattern of results. Taken together, these results show that where self-report is used as a measure of maternal responsiveness, teen mothers are no different in responsiveness than adult mothers; however, where physiological and interactional measures of responsiveness are considered, teen mothers are less likely to show heightened or selective responses to infant cries or respond 'attentively' to the infant.

    Objective To determine the pattern, challenges and correlates of condom use among Nigerians living with HIV Infection. Methods A cross sectional questionnaire study among HIV positive adults attending an HIV treatment centre in Lagos, Nigeria. Data entry and analysis were done with Epi-info version 3.5.1. Results The mean age of respondents was 35 (SD=7.7; range: 17-58 years) and mean age at sexual debut was 20 years old (range: 7-37 years). Majority were women (66.6%), had at least secondary school education(91.1%), married (68.2%)), on ART (50.7%) and knew their partners HIV status(60.9%). The rate of condom use at last sex act was 65.9%, but only 48.8% used condom consistently. Factors associated with condom use were male gender (OR=2.43, CI=1.35-4.33, P=0.002), less than secondary school education (OR=3.12, CI=1.04-9.28, P=0.05) and Not knowing partner's HIV status (OR=1.90, CI=1.04-3.80, P=0.04). Refusal to use condom (28.4%) were as a result of pregnancy intention, undesirability of condom in marriage and decreased sexual pleasure. Conclusion There is low consistent condom use rate of 48.8% among this cohort despite their exposure to behavioural change messages. A review of the present counselling strategy and combination prevention is therefore advocated. PMID:25183080

    Objective. The tyrosine kinase inhibitors have markedly changed the disease course for patients with Ph+ and/or BCR-ABL1+ chronic myeloid leukemia (CML). This study was embarked upon to assess the long-term effects of imatinib therapy on survival in adult Nigerian patients with CML. Methods. All adult patients on imatinib (400–600 mg) seen from July 2003 to December 2010 were assessed. Male/female distribution was 171/101, with a median age of 38 (range, 20–75) years. Overall survival (OS) and progression-free survival (PFS) were determined using the Kaplan-Meier techniques. Results. Of all the 272 patients, 205 were in chronic phase, 54 in accelerated phase, and five in blastic phase, at commencement of imatinib. As at December 2010, 222 were alive. OS at 1 and 5 years was 94% and 63%, while PFS was 89% and 54%, respectively. Similarly, amongst the 205 patients in chronic phase, OS at 1 and 5 years was 97% and 68%, while PFS was 92% and 57%. Conclusion. Imatinib's place as first-line therapy in the treatment of CML has further been reinforced in our patients, with improved survival and reduced morbidity, comparable with outcomes in other populations.

    The reproductive performance of Zebu cattle is generally low. However, blood concentrations of progesterone may be of practical value in assessing the reproductive status of the Zebu female. This paper reviews recent findings regarding plasma progesterone profiles during different phases of the reproductive cycle of some Nigerian Zebu cattle. The reproductive phases examined include the estrous cycle, early pregnancy and the postpartum periods. Our findings describe variations in plasma progesterone profiles observed under field conditions. The practical implications of these findings in assessing reproductive functions in indigenous Nigerian Zebu cattle are examined. PMID:16726505

    Inflammatory bowel disease (IBD) has been thought to have a low incidence among subSaharan Africans mainly because of the sporadic cases reported from the continent in comparison with the larger numbers reported from North America and Western European countries. Is this difference based on real demographic susceptibilities or a reflection of lower level of healthcare delivery? Three cases of ulcerative colitis and one case of Crohn's disease diagnosed in a tertiary institution in northern Nigeria in the span of three years are reported. Their presentation coincided with the creation of the Gastrointestinal Surgery Unit of our hospital and with it the availability of endoscopic diagnostic procedures. All four patients were indigenous Nigerians. Our findings suggest that IBD may be more common in this part of the world than previously thought. With an increased awareness of the disease in our population, a greater utilization of modern medicine as against alternative medicine and with wider availability of diagnostic tools in our hospitals, it is our guess that more cases may be found in the future to dispel the belief that Africans are somewhat immune to this affliction.

    The present study was carried out to ascertain frequency of multiple supernumerary teeth not associated with syndrome in Nigerians. A total of 13 patients comprising of 10 males (76.92%) and 3 female (23.07%) representing 0.098% of the study population had multiple supernumerary teeth. Multiple supernumerary teeth without any associated systemic diseases or syndrome are rare as reported by BLUMENTHAL (3) RUHLMAN and NEELY (17), KANTOR et al. (10) is not the case in this study. The maxillary region has the highest frequency of occurrence with 12 times (66.67%) followed by the mandibular premolar region with 4 times (22.22%) while maxillary premolar and mandibular anterior region shared (5.55%) respectively. The conical and tuberculate types of supernumerary teeth were found in the midline region, while the supplemental supernumerary teeth were more in the mandibular premolar region with 12 (70.58%) follow by maxillary midline 4 (23.52%) and the lower incisor region 1 (5.88%) which is in consonant with WINTER and BROOK (2), STAFNE (19) NAZIF, FUTALO ZULLO (15). The role of genetics in the aetiology of multiple supernumerary teeth as found in this study, the occurrence of supernumerary teeth on two brothers and a daughter to one of the affected brothers, tends, to suggest an autosomal dominant mode of inheritance and the challenges to management by the orthodontists are discussed.

    Data collected from 3,073 couples in four Nigerian cities and one semi-urban settlement were used to examine reproductive decision-making and male motivation for large family size. The report concludes that the characteristic male-dominant and patrilineal traditions support large family size and that men's reproductive motivation, to a large extent, affects the reproductive behavior of their wives. Therefore, the factors influencing men's reproductive outcomes and intentions are considered important for fertility transition in Nigeria. Male education, age at marriage, monogamy, interspousal communication, and intention not to rely on children for old-age support are significantly related to smaller actual family size and preferences for smaller families, while being in a male-dominant family setting has a strong relation with large family size and preferences for larger families. The policy implication of this study is the need for programs targeted at men and designed to change their attitudes about population matters and motivate them, and hence their wives, to produce smaller families.

    Responding effectively to an outbreak of disease often requires routine processes to be set aside in favour of unconventional approaches. Consequently, an emergency response situation usually generates ethical dilemmas. The emergence of the Ebola virus in the densely populated cities of Lagos and Port Harcourt in Nigeria brought bleak warnings of a rapidly expanding epidemic. However, these fears never materialised largely due to the swift reaction of emergency response and incident management organisations, and the WHO has now declared Nigeria free of Ebola. However, numerous ethical issues arose in relation to the response to the outbreak. This paper discusses some of these ethical challenges and the vital lessons learned. Ethical challenges relating to confidentiality, the dignity of persons, non-maleficence, stigma and the ethical obligations of health workers are examined. Interventions implemented to ensure that confidentiality and the dignity of persons improved and stigma was reduced, included community meetings, knowledge communication and the training of media personnel in the ethical reporting of Ebola issues. In addition, training in infection prevention and control helped to allay the fears of health workers. A potential disaster was also averted when the use of an experimental medicine was reconsidered. Other countries currently battling the epidemic can learn a lot from the Nigerian experience.

    Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogenetic trees using the maximum-likelihood approach to depict phylogenetic patterns of distribution among sequences. Our results show that Nigerian lions grouped together with lions from West and Central Africa. At the smaller geographical scale, lions from Kainji-Lake National Park in western Nigeria grouped with lions from Benin (located west of Nigeria), whereas lions from Yankari Game Reserve in central northeastern Nigeria grouped with the lion populations in Cameroon (located east of Nigeria). The finding that the two remaining lion populations in Nigeria have different phylogenetic origins is an important aspect to consider in future decisions regarding management and conservation of rapidly shrinking lion populations in West Africa.

    The AIDS epidemic in Nigeria is generalized, with infection primarily occurring through heterosexual transmission. It is important to understand patterns of sexual behavior to assess their impact on the epidemic and to design appropriate intervention strategies. This study examined risk factors for extramarital sex among Nigerian men, with a particular focus on polygyny and peri- and postpartum abstinence. Data from the 2003 Nigeria Demographic and Health Survey were analyzed for 1153 men and their wives. Eleven percent of men reported extramarital sex in the previous year. Logistic regression models showed that men with 3 or more wives were at the greatest risk for extramarital sex, followed by monogamous men, when compared with men with 2 wives. Other significant predictors included region, religion, wealth, age at sexual debut, and self-perceived risk of HIV infection. Peri- and postpartum abstinence was not significant. Based on these findings, HIV prevention programs should include men with 3 or more wives and those living in the southwest region, in addition to activities targeting men of all ages. Given the heterogeneity within Nigeria, further in-depth studies should be undertaken to explore the relation between number of wives, peri- and postpartum abstinence, and extramarital sex within specific communities.

    The toxicity and mutagenic potential of most African plants implicated in the management of cancer have not been investigated. The ethanolic extracts of selected Nigerian plants were subsequently studied using the brine shrimp lethality tests, inhibition of telomerase activity and induction of chromosomal aberrations in vivo in rat lymphocytes. Morinda lucida root bark, Nymphaea lotus whole plant and Garcinia kola root were active in the three test systems. Bryophyllum calycinum whole plant, Annona senegalensis root, Hymenocardia acida stem bark, Erythrophleum suaveolens leaves and Spondiathus preussii stem bark were toxic to brine shrimps and caused chromosomal damage in rat lymphocytes. Ficus exasperata leaves, Chrysophyllum albidum root bark and Hibiscus sabdariffa leaves were non-toxic to all the three test systems. Chenopodium ambrosioides whole plant was non-toxic to brine shrimps and rat lymphocyte chromosomes but showed inhibition in the conventional telomerase assay indicating a possible selectivity for human chromosomes. The result justified the use of the first eight plants and Chenopodium ambrosioides in the management of cancer in south west Nigeria although they appear to be non-selective and their mode of action may be different from plant to plant. All these plants except Chenopodium ambrosioides are also mutagenic and cytotoxic.

    Pleomorphic adenoma (PA) is the most common benign salivary gland tumor, accounting for up to 60% of all tumors of the salivary gland and 75-80% of all parotid tumors. It has a slow but progressive growth pattern and if untreated can become greatly enlarged in size. However, giant PA is uncommon. We report a case of giant parotid PA of more than 10 years duration in a 60-year-old male Nigerian. A 60-year-old male patient with 10-year history of painless, massive, and pedunculated swelling in the left side of lower face measuring 25 cm × 23 cm × 17 cm in dimension. Computerized tomographic scan and percutaneous fine needle aspiration cytology returned a preliminary diagnosis of PA. Superficial parotidectomy with facial nerve preservation via the transcervical approach was performed. The excised mass weighed 5.5 kg while the postoperative healing was satisfactory. Benign PAs may attain a giant size if left untreated. Socioeconomic problems are some of the reasons for late presentation. Adequate excision of the tumor sparing the facial nerve is possible but intraoperative and reactionary hemorrhage are likely complications. PMID:27538561

    In September 1991, Chevron Nigeria Ltd. and Nigerian National Petroleum Crop. contracted Offshore Pipelines to design, procure, construct, install, and commission the Opuekeba 30,000 b/d crude-oil flow station on an offshore platform near Olero Creek, Nigeria, approximately 22 miles from the nearest deepwater access. Chevron's original project plan included bringing the flow station to the site in small packages and then assembling it in a lengthy field hook-up process. Offshore Pipelines developed a plan early in the project to maximize construction and hook-up in the fabrication yard, then transport the nearly complete structures to site by way of a newly dredged canal. What proved to be most difficult was the site location in Nigeria. Job planning and communication were important in the successful completion of the project. Keeping the components of the large and complex facility simple proved to be effective and efficient and played a key role in completing the project on time and within budget. The paper discusses overcoming obstacles, lift and depth constraints, dredging, fabrication, installation, and large-time problems.

    Caffeine and theobromine contents (mg/g) were determined in samples of selected Nigerian beverage products. The beverages were cocoa (Milo, Bournvita, Rosevita and Enervita), coffee (Nescafe, Bongo, and Maxwell House decaffeinated) and tea (Lipton). The theobromine contents of samples of Milo, Bournvita, Rosevita, Enervita, Nescafe, Bongo, Maxwell House decaffeinated coffee and Lipton were 62.10+/-5.21, 64.80+/-6.72, 82.80+/-4.43, 80.37+/-6.80, 27.00+/-4.31, 14.67+/-2.90, 23.46+/-3.13 and 12.60+/-1.52, respectively. The corresponding caffeine contents of these samples were 2.78+/-0.43 (Milo), 3.17+/-0.36 (Bournvita), 0.92+/-0.51 (Rosevita), 1.05+/-0.68 (Enervita), 93.66+/-8.91 (Nescafe), 6.47+/-2.42 (Bongo), 37.22+/-5.34 (Lipton), and 0.21+/-0.11 (Maxwell House decaffeinated coffee). Semi-processed cocoa beverages (Rosevita and Enervita) had significantly (p < 0.05) higher levels of theobromine compared with the finished cocoas (Milo and Bournvita). Similarly, Nescafe contained significantly (p < 0.05) higher levels of caffeine compared to Maxwell House (decaffeinated coffee) and Bongo. Levels of caffeine in Lipton tea were moderate.

    BACKGROUND Pregnancy is a physiological process associated with an increased hemodynamic load and cardiac structural remodeling. Limited echocardiographic information exists on cardiac chambers, left ventricular (LV) systolic and diastolic functions, and LV mass during trimesters of normal pregnancy among African women. MATERIALS AND METHODS Echocardiography was done at the beginning of the second trimester, beginning of the third trimester, and middle of the third trimester for 100 normal pregnant women and at one visit for age-matched 100 nonpregnant women. The data were analyzed using the Statistical Package for Social Sciences (SPSS) version 17 software. Analysis of variance was used to compare within trimesters, and a P value of <0.05 was considered significant. RESULTS The mean (SD) ages of the patients and controls were 28.20 (±5.91) and 28.35 (±6.06) years, respectively (age range = 19–44 years, P = 0.86). Cardiac chambers, LV systolic function, and LV mass and its index increased significantly during pregnancy. A significant increase in A-wave velocity but slight increase in E-wave velocity and a reduction in tissue e′ velocity at the septal margin but a progressive increase in a′ velocity were also observed (P < 0.05). CONCLUSION Cardiac chamber dimensions, LV wall thickness, and mass, most indices of LV systolic and diastolic function, though within normal range, were significantly higher in pregnant than in nonpregnant Nigerian women.

    Among persons with posttraumatic stress disorder (PTSD), the severity of symptoms and concurrent distress are not fully explained by trauma severity. Interest has consequently arisen in the psychological processes that cause distress and heighten PTSD symptoms. This study accordingly sought to examine whether differences in metacognitive capacity are related to levels of emotional distress, avoidance/numbing, and hyperarousal. Participants were 48 adults with a confirmed diagnosis of PTSD. Comparison groups included 51 adults with HIV and 183 with schizophrenia. Metacognition, emotion recognition, depression, and emotional distress and levels of avoidance/numbing and hyperarousal were assessed concurrently using the Metacognition Assessment Scale-Abbreviated, the Bell Lysaker Emotion Recognition Test, the Beck Depression Inventory, and the Clinician-Administered PTSD Scale. Results revealed that the PTSD group had better ratings of overall metacognitive capacity than the schizophrenia group and specifically poorer levels of metacognitive mastery, or the ability to use metacognitive knowledge to respond to challenges, than the HIV group. Within the PTSD group, poorer metacognitive mastery was linked with greater distress and higher hyperarousal when depression was controlled for statistically. Emotion recognition was not linked with distress or symptom severity. Results are consistent with models in which symptom severity in PTSD is related to the extent to which persons can use knowledge of themselves and others to find ways to respond to distress that match their own unique needs.

    Objectives. To compare the severity of LUTS among middle aged and elderly Nigerian men and determine the influence of LUTS severity on QoL. Methods. This cross-sectional study was conducted among new patients presenting with LUTS attending Urology clinic between 2011 and 2015. Assessment of symptoms was based on IPSS and bother score completed by the eligible subjects on the same day of their clinic visits. Results. Four hundred patients were studied comprising 229 middle aged and 171 elderly men. Interquartile range (IQR) of IPSS scores for men <65 years and those ≥65 years was 14.0 (16.0) and 19 (15.0), respectively (p < 0.001). Mild LUTS was significantly associated with best, good, and poor quality of life while moderate LUTS was associated with poor QoL. Severe LUTS was significantly associated with all the categories of QoL (Best-Worst). Among the cohort of subjects with poor QoL, elderly patients had a significantly higher median IPSS score (p < 0.05). Conclusions. There is no level of severity of LUTS in which patients' QoL is not impaired although mild symptomatology may be associated with better QoL and severe symptomatology with poor QoL. Careful attention to QoL may help identify patients who require early and prompt treatment irrespective of the IPSS. PMID:27413368

    Regional contextual factors and dental caries using multilevel modeling related to adults in minority ethnic groups have been scantily explored. The influence of the socioeconomic context on self-reported dental caries (SRDC) in individuals of minority ethnic groups (IEG) in Colombia was studied. Data from the 2007 National Public Health Survey were collected in 34,843 participants of the population. The influence of different factors on SRDC in IEG was investigated with logistic and multilevel regression analyses. A total of 6440 individuals belonged to an ethnic group. Multilevel analysis showed a significant variance in SRDC that was smaller in IEG level than between states. Multilevel multivariate analysis also associated SRDC with increasing age, lower education level, last dental visit >1 year, unmet dental need and low Gross Domestic Product (GDP). Minority ethnic groups were at risk to report higher dental caries, where low GDP was an important variable to be considered.

A total of 201 subjects, made up of 101 dental patients (test group) matched with age and sex with 100 normal subjects (controls), was recruited into the study. All participants completed a designed socio-demographic questionnaire. General Health Question naire and Psyche ache Assessment Schedule were also administered to assess psychological distress based on cut-off scores ≥3 and emotional pain based on cut-off scores ≥28 respectively. The mean ages of study and control group were 33 (±12) and 36 (±13) years respectively, and both study and control groups were not significantly different in all the assessed socio-demographic parameters. Overall, 21.8% (n=22) of the subjects had psychological distress, while only 7% of the control group had psychological distress. This difference was statistically significant (P=0.003). Similarly, there was significant difference in the experience of psyche ache (unbearable psychological pain) as over a third of the dental patients (37.6%, n=38) had emotional pain, while only 13% of the controls experienced psych ache (P<0.001). In this study, the burden of psychological distress and emotional pain was many-fold in dental patients when compared with the controls. PMID:27403272

    BACKGROUND: Excessive erythrocytosis (EE) is a prevalent condition in populations living at high altitudes (> 2,500 m above sea level). Few large population-based studies have explored the association between EE and multiple subject-specific traits including oxygen saturation, iron status indicators, and pulmonary function. METHODS: We enrolled a sex-stratified and age-stratified sample of 1,065 high-altitude residents aged ≥ 35 years from Puno, Peru (3,825 m above sea level) and conducted a standardized questionnaire and physical examination that included spirometry, pulse oximetry, and a blood sample for multiple clinical markers. Our primary objectives were to estimate the prevalence of EE, characterize the clinical profile and iron status indicators of subjects with EE, and describe subject-specific traits associated with EE. RESULTS: Overall prevalence of EE was 4.5% (95% CI, 3.3%-6.0%). Oxygen saturation was significantly lower among EE than non-EE group subjects (85.3% vs 90.1%, P < .001) but no difference was found in iron status indicators between both groups (P > .09 for all values). In multivariable logistic regression, we found that age ≥ 65 years (OR = 2.45, 95% CI, 1.16-5.09), male sex (3.86, 1.78-9.08), having metabolic syndrome (2.66, 1.27-5.75) or being overweight (5.20, 1.95-16.77), pulse oximetry < 85% (14.90, 6.43-34.90), and % predicted FVC < 80% (13.62, 4.40-41.80) were strongly associated with EE. Attributable fractions for EE were greatest for being overweight (26.7%), followed by male sex (21.5%), pulse oximetry < 85% (16.4%), having metabolic syndrome (14.4%), and % predicted FVC < 80% (9.3%). CONCLUSIONS: We found a lower prevalence of EE than in previous reports in the Peruvian Andes. Although the presence of hypoxemia and decreased vital capacity were strongly associated with excessive erythrocytosis, being overweight or having metabolic syndrome were associated with an important fraction of cases in our study population.

  7. Agricultural communication and the African non-literate farmer: the Nigerian experience.

    PubMed

    Soola, E O

    1988-01-01

    In Nigeria, there lies a relatively untapped potential for great agricultural growth. Since the 1960's, Nigeria's "days of agricultural glory," there has been great obstacles in the exchange of information between scientists and Nigerian farmers. There has been a great trend in rural-urban migration and a rise in unemployment; crime and school drop outs have ensued. The Nigerian non-literate farmer is in a neglected class who has suffered the scrutiny and non-support of government and financial institutions. His growth has been limited because he is considered a poor credit risk. Because of his illiteracy, he is limited to traditional methods of farming. However, the Nigerian farmer is not uneducable. He is information-conscious and can be instructed if a communicator is sensitive to the farmer's culture, tradition and farming practices. An agriculture extension agent must not only assess the farmer's needs but also convey relevant information in a manner that is amenable to the farmer's framework of communication. Working with opinion leaders, the mass media, a regional library, audio tapes and by portraying new information and farming practices through festivals and ceremonies are methods available to the extension agent or communicator in his work with the non-literate Nigerian farmer.

    1993-03-01

    Anecdotal reports have attributed persistent splenomegaly in African sickle cell anemia (SS) patients to the effects of malaria. However, no comparative studies of patients in malarial and nonmalarial regions have been conducted, and few studies of malaria antibody titers have been reported. In the present study, age- and sex-matched Nigerian patients (n = 310), while it was found only in 8% of U.S. patients (n = 100) from Georgia. There was significant linear correlation between spleen size and Hb levels and with serum immunoglobulins in the Nigerian group. However, serum complement levels (C3 and C4) were not affected by spleen size. In both groups, patients with splenomegaly had fewer circulating pitted red cells than their counterparts without splenomegaly. The mean +/- SE of IgG-specific malaria antibody titer among the Nigerian patients without palpable spleens was 9,386 +/- 2,036; 9,334 +/- 2,980 in those with spleens between 1 and 5 cm, 16,201 +/- 4,502 in those with spleens between 6 and 10 cm, and 22,445 +/- 8,456 in those with spleens above 10 cm. Coexistent alpha-thalassemia did not influence the prevalence of splenomegaly among the Nigerian SS patients. This study provides additional evidence that malaria plays a significant role in the persistence of splenomegaly in African patients. PMID:8438905

    Fadare, Joseph O.; Desalu, Olufemi O.; Jemilohun, Abiodun C.; Babatunde, Oluwole A.

    2012-01-01

    Background: The knowledge of medical ethics is essential for health care practitioners worldwide. The main objective of this study was to evaluate the knowledge of medical doctors in a tertiary care hospital in Nigeria in the area of medical ethics. Materials and Methods: A cross-sectional questionnaire-based study involving 250 medical doctors of different levels was carried out. The questionnaire, apart from the bio-data, also sought information on undergraduate and postgraduate training in medical ethics, knowledge about the principles of biomedical ethics and the ethical dilemmas encountered in daily medical practice. Results: One hundred and ninety (190) respondents returned the filled questionnaire representing a response rate of 76%. One hundred and fifty-two respondents (80%) have had some sort of medical ethics education during their undergraduate level in the medical education. The median duration of formal training or exposure to medical ethics education was 3.00 hours (range: 0-15). One hundred and twenty-nine respondents have read at least once the code of medical ethics of the Medical and Dental Council of Nigeria while 127 (66.8%) have some general knowledge of the principles of biomedical ethics. The breakdown of the identified ethical dilemmas shows that discharge against medical advice was the most identified by the respondents (69.3%) followed by religious/cultural issues (56.6%) while confidentiality was recognized by 53.4%. Conclusion: The knowledge of medical ethics by Nigerian medical doctors is grossly inadequate. There is an urgent need for enhancement of the teaching of the discipline at both undergraduate and postgraduate levels in Nigeria. PMID:23661883

    2015-02-01

    This study assessed the effects of rifapentine or rifampin on the pharmacokinetics of a single dose of bedaquiline and its M2 metabolite in healthy subjects using a two-period single-sequence design. In period 1, subjects received a single dose of bedaquiline (400 mg), followed by a 28-day washout. In period 2, subjects received either rifapentine (600 mg) or rifampin (600 mg) from day 20 to day 41, as well as a single bedaquiline dose (400 mg) on day 29. The pharmacokinetic profiles of bedaquiline and M2 were compared over 336 h after the administration of bedaquiline alone and in combination with steady-state rifapentine or rifampin. Coadministration of bedaquiline with rifapentine or rifampin resulted in lower bedaquiline exposures. The geometric mean ratios (GMRs) and 90% confidence intervals (CIs) for the maximum observed concentration (Cmax), area under the concentration-time curve to the last available concentration time point (AUC0-t), and AUC extrapolated to infinity (AUC0-inf) of bedaquiline were 62.19% (53.37 to 72.47), 42.79% (37.77 to 48.49), and 44.52% (40.12 to 49.39), respectively, when coadministered with rifapentine. Similarly, the GMRs and 90% CIs for the Cmax, AUC0-t, and AUC0-inf of bedaquiline were 60.24% (51.96 to 69.84), 41.36% (37.70 to 45.36), and 47.32% (41.49 to 53.97), respectively, when coadministered with rifampin. The Cmax, AUC0-t, and AUC0-inf of M2 were also altered when bedaquiline was coadministered with rifapentine or rifampin. Single doses of bedaquiline, administered alone or with multiple doses of rifapentine or rifampin, were well tolerated, with no safety concerns related to coadministration. Daily administration of rifapentine to patients with tuberculosis presents the same drug interaction challenges as rifampin and other rifamycins. Strong inducers of the cytochrome P450 isoenzyme CYP3A4 should be avoided when considering the use of bedaquiline. (This study is registered at clinicaltrials.gov under identifier NCT02216331

    This study explored the mediating role of sleep in the relationship between personality traits and depressive symptoms in a group of community-dwelling men and women (Mage = 57.92, SD = 4.00). Participants completed the short form NEO Five Factor Inventory (NEO-FFI), Pittsburgh Sleep Quality Index (PSQI), and the Center for Epidemiologic Studies Depression Scale (CES-D). High neuroticism and low conscientiousness was associated with poor sleep, as well as greater depressive symptom severity. Partial indirect mediation effects were found between personality traits (i.e., neuroticism and conscientiousness) and depressive symptoms through self-report sleep measures. An alternative model was also explored, entering depression as the mediator; however a smaller portion of the variance was explained by this model, compared with the hypothesized model. The current study provides preliminary information regarding the mechanisms that influence the relationship between personality traits, sleep, and depression among a group of community-dwelling middle-aged adults. Implications and future directions are discussed. PMID:27285159

    Background: Menopause represents the end of women reproductive career and it is at this time they begin to manifest morbidities such as urinary incontinence. Aim: To document proximate determinants of sexual activity and urological morbidities of menopausal women. Subjects and Methods: This was a community survey conducted among 254 menopausal women Mokola in Ibadan, Nigeria in 2008. Respondents were selected using cluster sampling technique. Interviewer administered questionnaires were used to obtain information on their characteristics, pattern of urological and sexual activities. Descriptive, bivariate and multivariable tests were performed with Statistical Package for the Social Sciences 15.0 (Chicago, IL USA) and statistical significance was set at P value less than 0.05. Results: The mean age of subjects was 60.3 (standard deviation = 10.2 years). About 33.5% (85/254) was still sexually active. About 68% (173/254) reported a reduction in sexual frequency since menopause while 31.5% (80/254) reported no change. The mean self-rated sexual performance score was 4.3 based on a numerical scale where 10 is the maximum obtainable. Significant predictors of reduction in sexual activity were age at menopause and education. Those between 45 and 49 years were less likely than those at 55 years or more (odds ratio [OR] = 0.21; 95% confidence interval OR = 0.05-0.87) while women with at least secondary education were thrice less likely than those with none to report a reduction in sexual activity after menopause. Less than a tenth reported urinary incontinence as a complaint. Urge incontinence was the most commonly reported followed by dysuria and stress incontinence. Less than a quarter of them had requested for a form of treatment. Conclusion: Sexual performance of Nigerian menopausal women is associated with age at menopause and education. Non-fistulous urinary incontinence is now being mentioned as a complaint contrary to the widely held view that it is part of the

    The prevalence of obesity is increasing in children and adolescents even in resource-poor countries. The study aimed to determine the prevalence of obesity in a group of Nigerian school children using triceps skin-fold thickness (SFT) and body mass index (BMI). The subjects were 1235 randomly selected primary and secondary Lagos school children aged 5-18 years, triceps SFT was measured with Harpenden® calipers and BMI calculated from weight and height. Using BMI, overweight and obesity were defined as values of 85th to 94th percentile for age and sex and ≥95th percentile, respectively. Using triceps SFT, obesity was defined as SFT > 85th percentile of the NHANES III study. Fifty-seven subjects (15 boys and 42 girls) had SFT > 85th percentile with a higher prevalence in girls than boys (6.4% vs. 2.6%, P = 0.001). The prevalence of BMI-defined overweight and obesity were also higher among girls (11.9% vs. 5.7%, P < 0.001 and 4.7% vs. 2.2%, P = 0.02, respectively). Females of upper socioeconomic class were more likely to be overweight (16.2% vs. 6.6%, P < 0.0001), obese (6.3% vs. 2.8%, P = 0.03) or have elevated SFT (8.2% vs. 4.2%, P = 0.03) than those of low socioeconomic status. Forty-seven of 57 subjects (82.5%) with elevated SFT also had high BMI. The prevalence of obesity is low in the study population but the much higher prevalence of overweight suggests that steps should be taken to control fatness before the figures worsen. In more than 80% of subjects, elevated SFT co-existed with elevated BMI.

    Although infertility causes women considerable grief, social stigma, and economic deprivation, scholars have paid little attention to infertility’s definitions that may depart from the standard Western usage and how such definitions influence the way women experience the condition. This article, by listening to individual women’s experiences of infertility in two Nigerian communities, examines these definitions and differentiates between culturally salient categories of infertility. In distinguishing between different kinds of childless women and those with low fertility, we intend to enhance understandings of infertility by considering women’s subjective understandings of the condition and thus moving beyond the current medical definition. By comparing women’s experiences in two different ethnic groups in Nigeria, we show how distinct forms of kinship structures and social organizations shape the ways low fertility is defined, managed, and experienced.

    Objective: Level of response to alcohol has been associated with risk of alcohol dependence in a number of ethnic groups. In the present study, subjective and objective responses to alcohol were evaluated in Indo-Trinidadians (Indo-T) and Afro-Trinidadians (Afro-T). Associations of alcohol dehydrogenase polymorphisms with response to alcohol, using the Subjective High Assessment Scale (SHAS), and breath alcohol concentrations (BrAC) were tested. Method: Regular male drinkers without alcohol dependence (n = 112) ages 18–25 years participated in alcohol challenge sessions consisting of placebo and two doses of alcohol (target BrAC: 0 g/dl for placebo, .04 g/dl low dose, and .08 g/dl high dose) and genotyped for variants in ADH1B*3 and ADH1C*2. Results: Indo-T had significantly higher BrAC, pulse rates, and cortisol levels when compared with Afro-T but did not have significantly higher SHAS values. Higher responses on the SHAS items muddle/confused and nauseated were significantly associated with the presence of at least one ADH1B*3 allele following the high dose of alcohol in Afro-T. Indo-T with at least one ADH1C*2 allele displayed significantly different Drug × Time interactions for the SHAS item effects of alcohol at the low dose and for the SHAS items clumsy, muddle/confused, effects of alcohol, floating, drunk, and total at the high dose from Indo-T with two ADH1C*1 alleles. Conclusions: This is the first study that has investigated individual sensitivity to alcohol in a Caribbean population and in people of East Indian descent. Indo-T with at least one ADH1C*2 allele may be at higher risk for heavy drinking by feeling less of the effects of alcohol, including nausea. In Afro-T, having at least one ADH1B*3 allele appears to exert a protective effect by enhancing the unpleasant effects of alcohol, such as nausea and confusion. PMID:25208201

    Cabozantinib is a small molecule tyrosine kinase inhibitor that has been approved for the treatment of patients with progressive, metastatic medullary thyroid cancer. Cabozantinib exhibits a pH-dependent solubility profile in vitro. Two phase 1 clinical pharmacology studies were conducted in healthy subjects to evaluate whether factors that may affect cabozantinib solubility and gastric pH could alter cabozantinib bioavailability: a food effect study (study 1) and a drug-drug interaction (DDI) study with the proton pump inhibitor (PPI) esomeprazole (study 2). Following a high-fat meal (study 1), cabozantinib Cmax and AUC were increased (40.5% and 57%, respectively), and the median tmax was delayed by 2 hours. Cabozantinib should thus not be taken with food (patients should not eat for at least 2 hours before and at least 1 hour after administration). In the DDI study (study 2), the 90% confidence intervals (CIs) around the ratio of least-squares means of cabozantinib with esomeprazole versus cabozantinib alone for AUC0-inf were within the 80%-125% limits; the upper 90%CI for Cmax was 125.1%. Because of the low apparent risk of a DDI, concomitant use of PPIs or weaker gastric pH-altering agents with cabozantinib is not contraindicated. PMID:25907407

    Social isolation among the elderly is a concern in developed countries. Using a randomized trial, this study examined the effect of a social isolation prevention program on loneliness, depression, and subjective well-being of the elderly in Japan. Among the elderly people who relocated to suburban Tokyo, 63 who responded to a pre-test were randomized and assessed 1 and 6 months after the program. Four sessions of a group-based program were designed to prevent social isolation by improving community knowledge and networking with other participants and community "gatekeepers." The Life Satisfaction Index A (LSI-A), Geriatric Depression Scale (GDS), Ando-Osada-Kodama (AOK) loneliness scale, social support, and other variables were used as outcomes of this study. A linear mixed model was used to compare 20 of the 21 people in the intervention group to 40 of the 42 in the control group, and showed that the intervention program had a significant positive effect on LSI-A, social support, and familiarity with services scores and a significant negative effect on AOK over the study period. The program had no significant effect on depression. The findings of this study suggest that programs aimed at preventing social isolation are effective when they utilize existing community resources, are tailor-made based on the specific needs of the individual, and target people who can share similar experiences.

    Objective To examine whether intra- and intergenerational caregiving affect subjective well-being (SWB) of the caregivers longitudinally. Methods Data were drawn from the German Ageing Survey (DEAS), which is a population-based longitudinal study of individuals living in Germany aged 40 and over. The waves in 2002, 2008 and 2011 were used (with 10,434 observations). SWB was examined in a broad sense, covering affective (AWB) and cognitive well-being (CWB), positive (PA) and negative affect (NA) as well as functional and mental health. While intragenerational caregiving was defined as providing care for spouse/partner, intergenerational caregiving was defined as providing care for mother, father, mother-in-law, father-in-law, partner’s mother or partner’s father. Results Fixed effects regressions adjusting for sociodemographic factors, social network, self-efficacy and morbidity showed that intergenerational informal care did not affect the various SWB outcome measures. Intragenerational caregiving affected CWB (women) and mental health (total sample and men), whereas it did not affect the other outcome variables. Conclusion Our findings highlight the importance of intragenerational caregiving for mental health (men) and cognitive well-being (women). Consequently, interventions to avoid mental illness due to intragenerational caregiving are urgently needed. PMID:26859511

    Objectives: To determine the dimensions of normal pituitary gland using T1-weighted magnetic resonance images (MRI) and to determine their relationship with age and sex. Materials and Methods: Cranial MRI scans of 100 individuals with clinically normal pituitary function (58 males and 42 females) and in the age range 14–82 years were reviewed in order to obtain volumetric measurements of the pituitary gland. The height, width, and depth of the pituitary were obtained from mid-sagittal and coronal planes, while the volume was calculated from these measured parameters. The data obtained were stratified based on age and sex for analysis. Statistical tests applied included Student's t-test and Pearson correlation. A minimum level of statistical significance was set at P < 0.05. Results: The mean pituitary volumes were 334.1 ± 145.8 mm3 and 328.1 ± 129.2 mm3 while the mean pituitary heights were 6.45 ± 1.7 mm and 6.46 ± 1.57 mm in males and females, respectively. Although there was no statistically significant difference between pituitary height and pituitary volume in both sexes, they correlated negatively with increasing age (r = −202, P = 0.04 and r = −410, P = 0.000, respectively). Both parameters were highest in pubertal subjects and declined steadily with age, with a second peak occurring only for pituitary height in the sixth decade. The mean pituitary widths (9.08 ± 2.59 mm and 9.21 ± 1.86 mm) and depths (10.59 ± 1.71 mm and 10.49 ± 1.57 mm) in males and females, respectively, did not show remarkable changes with age and sex in the individuals studied. Conclusion: With this study, we have provided reference values in Nigerian population for the dimensions of normal pituitary gland, in order to facilitate assessment and diagnosis in patients with abnormalities of the hypothalamic–pituitary axis.

    Background Nigeria has one of the highest burdens of pneumococcal disease in the world, but accurate surveillance is lacking. Molecular detection of infectious pathogens in dried blood spots (DBS) is an ideal method for surveillance of infections in resource-limited settings because of its low cost, minimal blood volumes involved, and ease of storage at ambient temperature. Our study aim was to evaluate a Streptococcus pneumoniae real-time polymerase chain reaction (rt-PCR) assay on DBS from febrile Nigerian children on Whatman 903 and FTA filter papers, compared to the gold standard of culture. Methods Between September 2011 to May 2015, blood was collected from children 5 years of age or under who presented to six hospital study sites throughout northern and central Nigeria with febrile illness, and inoculated into blood culture bottles or spotted onto Whatman 903 or FTA filter paper. Culture and rt-PCR were performed on all samples. Results A total of 537 DBS specimens from 535 children were included in the study, of which 15 were culture-positive for S. pneumoniae. The rt-PCR assay detected S. pneumoniae in 12 DBS specimens (2.2%). One positive rt-PCR result was identified in a culture-negative specimen from a high-risk subject, and two positive rt-PCR results were negative on repeat testing. Six culture-confirmed cases of S. pneumoniae bacteremia were missed. Compared to culture, the overall sensitivities of Whatman 903 and FTA DBS for detection of S. pneumoniae were 57.1% (95% CI 18.4–90.1%) and 62.5% (95% CI 24.5–91.5%), respectively. Nonspecific amplification was noted in an additional 22 DBS (4.1%). Among these, six were positive for a non-S. pneumoniae pathogen on culture. Conclusions Rt-PCR was able to detect S. pneumoniae from clinical DBS specimens, including from a culture-negative specimen. Our findings show promise of this approach as a surveillance diagnostic, but also raise important cautionary questions. Several DBS specimens were detected as

    Study Objectives: To evaluate the next-morning residual effects of ramelteon (8 mg), zopiclone (7.5 mg), and placebo on driving performance, memory functioning, psychomotor performance, and mood in healthy adult subjects following bedtime dosing and a middle of the night awakening. Design: Single-center, randomized, double-blind, double-dummy, placebo-controlled, crossover study. Setting: Utrecht University, The Netherlands. Participants: 30 healthy volunteers (15 males and 15 females). Interventions: a single dose of ramelteon (8 mg), zopiclone (7.5 mg), and placebo, administered at bedtime. Measurements: A balance test was performed at night. Other tests were performed the following morning, 8.5 h after administration. Subjects performed a 100-km highway driving test in normal traffic. Primary outcome measure was the standard deviation of the lateral position (SDLP), i.e., the weaving of the car. After driving, cognitive, memory, and psychomotor tests were performed and mood was assessed. Results: SDLP was significantly increased after the intake of ramelteon (+2.2 cm) and zopiclone (+2.9 cm). Ramelteon and zopiclone produced significant impairment on reaction time (P < 0.024) in the Sternberg Memory Scanning Test, slow (P < 0.007) and fast (P < 0.010) tracking, reaction speed (P < 0.015) and tracking (P < 0.001) in the Divided Attention Test, and delayed recall (P < 0.032) in the Word Learning Test. In contrast to ramelteon, zopiclone additionally impaired performance on the Digit Symbol Substitution Test (P < 0.001) and the balance test (P < 0.001). Conclusions: Ramelteon (8 mg) and zopiclone (7.5 mg) significantly impaired driving performance, cognitive, memory, and psychomotor performance the morning following bedtime administration. In contrast to zopiclone, ramelteon produced no balance impairments.

    Nowadays, an electronic health information management system (EHIMS) is crucial for patient care in hospitals. This paper explores the aspects and elements that contribute to the success of EHIMS in Nigerian teaching hospitals. The study adopted a survey research design. The population of study comprised 442 health information management personnel in five teaching hospitals that had implemented EHIMS in Nigeria. A self-developed questionnaire was used as an instrument for data collection. The findings revealed that there is a positive, close relationship between all the identified factors and EHIMS's success: technical factors (r = 0.564, P < 0.05); social factors (r = 0.616, P < 0.05); organizational factors (r = 0.621, P < 0.05); financial factors (r = 0.705, P < 0.05); and political factors (r = 0.589, P < 0.05). We conclude that consideration of all the identified factors was highly significant for the success of EHIMS in Nigerian teaching hospitals.

    One of the contributory factors in the establishment of occlusion is the child's oral habits. A limited amount of information is available on oral habits of pre-school children especially on Nigerian pre-school children. With an increasing interest in the early recognition of mal-occlusion and a corresponding emphasis on preventive procedures, more information on pre-school children may prove to be useful. This study revealed the prevalence of oral habits among 563 Nigerian pre-school children aged 3-5 years at 13.14%: 6.74% for males, 6.4%for females. The acquired data were tested with chi-square(chi2). The results indicate significant gender difference for tongue thrusting/sucking only (P=0.01) using the fisher's exact test. The relationship between digital sucking habit and mal-occlusion was very significant (P<0.01).

  14. A comparative analysis of noss profiles on nigerian and American preservice, secondary science teachers

    NASA Astrophysics Data System (ADS)

    Cobern, William W.

    In this study American preservice science TEACHERS' responses on Kimball's Nature of Science Survey (NOSS) were used as a basis for analyzing the sense of the nature of science held by a group of Nigerian preservice science teachers. From an item-by-item comparison two salient differences were noted. These differences are quite interesting and important, and one would expect to see replication attempts in the near future. The primary difference was that the Nigerian students were much more inclined to see science as a way of producing useful technology. Given the national interests of a developing nation this is an understandable perception and one common among government policy makers. Nevertheless, it is a view with potential long-range dangers if this view of science is effectively transferred from teacher to student. For example, such a view is likely to raise false expectations in the general population, which when not achieved could result in widespread rejection of science. The second distinctive of the Nigerian students' sense of the nature of science had to do with the openness of science. These students perceived scientists as nationalistic and secretive about their work. This finding is troubling and indicates an important line of investigation: What image of science, especially Western science, is carried in the international media? How is that image understood in non-Western nations? What are the implications for international scientific cooperation?

    Morbidity and mortality from asthma continues to increase worldwide. Investigations conducted in Western countries have shown that psychiatric morbidity may play a role in increasing mortality due to asthma. However, the association between psychopathology and asthma has not been fully investigated among Nigerian patients. 50 asthmatics seen in the Chest Clinic of the Obafemi Awolowo University Teaching Hospital Complex (OAUTCH), Ile-Ife, were examined using the 30-item general health questionnaire (GHQ-30). A control group of 48 Nigerians with a similar socio-demographic background were also studied. A significantly higher prevalence of psychiatric disorder (50%) were found in the asthmatic group, while only 27.1% of the control group had psychopathology. Twenty-one (87.5%) of the asthmatics with frequent attacks had psychopathology compared to only four (25%) with less frequent attacks. Psychiatric morbidity did not show any relationship to the level of educational attainment or other socio-demographic variables. This result suggests a high prevalence of psychiatric morbidity among Nigerian asthmatics. The management of asthma should take a wholistic approach: physical, as well as the psychosocial factors should be considered. PMID:12443002

    Natural gas (NG) has been regarded as a bridge fuel toward renewable sources and is expected to play a greater role in future global energy mix; however, a high degree of uncertainty exists concerning upstream (well-to-tank, WtT) greenhouse gas (GHG) emissions of NG. In this study, a life-cycle (LC) model is built to assess uncertainty in WtT GHG emissions of liquefied NG (LNG) supplied to Europe by Nigeria. The 90% prediction interval of GHG intensity of Nigerian LNG was found to range between 14.9 and 19.3 g CO2 eq/MJ, with a mean value of 16.8 g CO2 eq/MJ. This intensity was estimated considering no venting practice in Nigerian fields. The mean estimation can shift up to 25 g CO2 eq when considering a scenario with a higher rate of venting emissions. A sensitivity analysis of the time horizon to calculate GHG intensity was also performed showing that higher GHG intensity and uncertainty are obtained for shorter time horizons, due to the higher impact factor of methane. The uncertainty calculated for Nigerian LNG, specifically regarding the gap of data for methane emissions, recommends initiatives to measure and report emissions and further LC studies to identify hotspots to reduce the GHG intensity of LNG chains.

    2014-01-01

    Background The study examined the knowledge and attitudes to personal genomics testing for complex diseases among Nigerians and identified how the knowledge and attitudes vary with gender, age, religion, education and related factors. Methods Data were collected using qualitative method in 2 districts of the Federal Capital Territory. In the study, eight (8) Focused Group Discussions (FGDs) and twenty seven (27) Key Informant Interviews (KIIs) were conducted. Participants for the research were recruited among healthy Nigerians, individuals with complex diseases, health care professionals, community leaders and health policy makers. Result Analysis of the result showed that most respondents in both FGDs and KIIs had limited knowledge about genomics test initially. Their understanding of the test however improved after explanation on its concept. Participants showed positive attitude towards genomics tests. Nevertheless they expressed fear over direct to consumer personal genomics testing, testing unborn babies and disclosure of results to third parties. Culture and religion were found to influence the perspectives of respondents on genomics test particularly those aspects that could either directly contradict their beliefs and practices or lead to actions which contradict them. Conclusion In conclusion, most Nigerians interviewed had limited knowledge of genomics test but with supportive attitude towards its use in predicting future risk of complex diseases after understanding the test concept. Genomics testing for complex diseases was not a common practice in Nigeria. PMID:24766930

    of natural and man-made disasters but will also be used for monitoring rapidly changing and dynamic aspect of agriculture, the environment, pipeline oil spillages and other national remote sensing requirements. Commercial exploitation of this unique 24hr revisit EO data is planned to offset the government investment. The second national project is NigeriaSAT-2, which is a geostationary communications minisatellite that has been selected specifically to address the lack of communications infrastructure in Nigeria. Both NigeriaSAT-1 and NigeriaSAT-2 projects are being carried out in co-operation with the Surrey Space Centre (UK), combined with a detailed space know-how transfer and training to build up an indigenous Nigeria capability in space technology, EO and communications. While the acquisition and development space technology is the prime focus of the national space programme, an application center, education center and various space research centers are being formed to draw the maximum benefit of space activities for Nigeria. The paper will present the experience of Nigeria in examining the cost/benefit of an affordable space programme based upon small satellites with real applications that will benefit the people of the country. The Nigerian space policy and programme and its first two small satellite projects (NigeriaSAT-1/DMC and NigeriaSAT-2/GEMINI) will also be presented. This paper focuses on how a developing country can take advantage of a cheap and efficient means of gaining access to space and using space technology in achieving its socio-economic development plans.

    Objectives: Breaking of medical bad news is anecdotally deemed culturally unacceptable, even intolerable, to native Africans. We explored this hypothesis among a cohort of relatives of patients who had difficult neurosurgical diagnoses in an indigenous practice. Materials and Methods: A semi-structured, interviewer-administered questionnaire was used in a cross-sectional survey among a consecutive cohort of surrogates/relatives of concerned patients. Their opinion and preferences regarding the full disclosure of the grave neurosurgical diagnoses, and prognoses, of their wards were analyzed. Results: A total of 114 patients’ relatives, 83 (72.8%) females, were sampled. They were mainly young adults, mean age 40.2 (SD 14.2) years; 57% had only basic literacy education; but the majority, 97%, declared themselves to have serious religious commitments. Ninety nine percent of the study participants deemed it desirable that either they or the patients concerned be told the bad news; 80.7% felt that this is best done with both patients and relations in attendance; 3.5% felt only the patients need be told. These preferences are similar to those expressed by the patients themselves in an earlier study. But a nearly significant greater proportion of patients’ relatives (15 vs 5%, p = 0.06) would rather be the only ones to be told the patients’ bad news. Conclusion: This data-driven study showed that contrary to anecdotal belief about them, a cohort of native Nigerian-African surrogates of neurosurgical patients was well disposed to receiving, and appeared able to handle well, the full disclosure of difficult medical diagnostic/prognostic information.

    2013-06-01

    This study examines the modes of framing mental illness in the Yoruba genre of Nigerian movies. All Yoruba films on display in a convenient sample of movie rental shops in Ibadan (Nigeria) were sampled for content. Of the 103 films studied, 27 (26.2%) contained scenes depicting mental illness. Psychotic symptoms were the most commonly depicted, while effective treatments were mostly depicted as taking place in unorthodox settings. The most commonly depicted aetiology of mental illness was sorcery and enchantment by witches and wizards, as well as other supernatural forces. Scenes of mental illness are common in Nigerian movies and these depictions-though reflecting the popular explanatory models of Yoruba-speaking Nigerians about mental illness- may impede utilization of mental health care services and ongoing efforts to reduce psychiatry stigma in this region. Efforts to reduce stigma and improve service utilization should engage the film industry. PMID:23670966

    In an effort to shed more light on the tolerance of indigenous chickens to coccidiosis, we compared the body weight, faecal oocyst load and haematological parameters based on sex and genotypes of Eimeria tenella-infected chickens. Three hundred chicks from three genotypes (normal-feathered, frizzle-feathered and naked-neck) of Nigerian indigenous chickens which comprised 100 birds per genotype were raised for 6 weeks. At 3 weeks old, each chick was weighed and faecal, and blood samples were collected before inoculation. Subsequently, the birds were weighed and faecal samples collected at days 1, 3, 6, 9, 12 and 15 post-inoculation. Blood samples were collected from 50 chicks per genotype at 3 and 5 weeks post-inoculation. Blood parameters were determined and faecal samples subjected to McMaster egg counting technique. Results showed genotype, and sex had significant effects on body weight from day 1 to 15 post-inoculation. Normal-feathered chicks had the highest body weight while frizzle-feathered chicks showed lowest body weight at post-inoculation. E. tenella was identified in caecal and lower intestinal mucosa of the genotypes, but genotype had no significant effect (p > 0.05) on the lesion score. There were no significant differences in haematological values among genotypes (p > 0.05) except for lymphocytes where naked-neck chicks had the highest lymphocytes' count (1.83 ± 0.02 %), followed by normal-feathered (1.79 ± 0.02 %) and the frizzle-feathered (1.68 ± 0.02 %). The present values of body weight, faecal oocyst and haematological parameters obtained seemed not to be convincing enough to suggest that the genotypes were different in terms of tolerance to coccidiosis.

    Background: Propolis is a bee (Apis mellifera) product of plant origin with varied chemical composition depending on the ecology of the botanical origin. It has been reported in literature to possess various therapeutic effects both traditionally, clinical trial, and animal study. Objectives: In the present study bioactive principle in methanol extract of Nigerian bee (A. mellifera) propolis was determined by gas chromatography-mass spectrometry (GC/MS) study. Materials and Methods: The methanol extract of Nigerian bee (A. mellifera) propolis was characterized for its chemical composition by preliminary phytochemicals screening and GC/MS analysis using standard procedures and methods. Results: Phytochemical screening revealed the presence of flavonoids, saponins, alkaloids, tannins, cardiac glycosides, anthraquinones phlobatannins, and steroids while GC/MS chromatogram revealed nineteen peaks representing 60 different chemical compounds. The first compounds identified with less retention time (RT) (13.33s) were methyl tetradecanoate, tridecanoic acid, methyl ester, decanoic acid, methyl ester while squalene, all-trans-squalene, 2,6,10-dodecatrien-1-ol, 3,7,11-trimethyl-, (E,E)- and farnesol isomer a took longest RT (23.647s) to identify. Methyl 14-methylpentadecanoate, hexadecanoic acid methyl ester, methyl isoheptadecanoate, and methyl tridecanoate were the most concentrated constituent as revealed by there peak height (26.01%) while eicosanoic acid was the least concentrated (peak height 0.81%) constituent of Nigerian bee propolis. Conclusion: The presence of these chemical principles is an indication that methanol extract of Nigeria bee propolis, if properly screened could yield a drug of pharmaceutical importance.

    This study was undertaken to assess the effects of antenatal care and parity on birthweights. The study also enables determination of the average birthweight of Nigerian's newborns. Conducted in Ile-Ife University Teaching Hospital and Enuwa Maternity Centre, respective data on babies born in 1980 were obtained from antenatal and delivery record books of the 2 institutions. Social characteristics of the mothers, their parity, and sex and birthweight of the newly born babies were recorded. Only data on the 2804 live spontaneous deliveries were considered for this study. 95.4% mothers were Yorubas, and the rest were from other ethnic groups in Nigeria. 2418 mothers were booked (pre-registered) in the hospitals and received antenatal care; the remaining 386 were unbooked. Mean birth weight was 3.113 +or- 0.456 kg. and 3.056 +or- 0.485 kg. for the unbooked pregnancies. However, these differences in birthweights were not statistically significant. The term low birth weight (LBW) infant was used for the newborn weighing 2500 gr or less (WHO, 1961). The incidence of LBW in the unbooked pregnancies was higher than in the booked ones, and was statistically significant. The overall MBW of 3.086 +or- 0.432 kg. was slightly higher than most other studies done for Nigerian babies. These studies support the view that antenatal care influences the development of the fetus, and that poor nutritional practice as a result of traditional beliefs among pregnant Nigerian women is responsible for inadequate weight gain during pregnancy. Intensive nutritional education during visits to antenatal clinics is advocated to correct erroneous beliefs. The study also showed a consistent increase in MBW with increasing parity, indicating successive childbirths may become increasingly strenuous, especially with the occurrence of cephalopelvic disproportion as fetal size increases. There is an urgent need for extensive collaborative studies in different parts of African countries on specific

    Ash fouling during heat transfers in coal power-plants has been known to be an engineering problem caused by high sodium levels of the feed-coals. Instrumental Neutron Activation Analysis (INAA) was used in determining the concentration of some alkali elements (Na, Ca, Mg) associated with ash fouling for eight Nigerian coals mined at Onyeama, Ogbete, Enugu, Gombe, Okaba, Afikpo, Lafia and Asaba. Sodium levels were generally low (0.001-0.036%). Oxygen concentrations considered as an indicative measure of the wettability of each of the coals were determined. The possible effects of the concentration of these elements on ash fouling were discussed. 8 refs., 3 tabs.

    Inadequate attention given to the management of asthma and ways of improving treatment could be a significant factor for the increase morbidity and mortality from asthma despite major advances in our understanding of the pathophysiology of the disease. There seems to be paucity of data concerning the management pattern and burden of asthma in Africa. This study was under taken to determine the prevalence, management pattern and the burden of asthma. This study was a cross sectional design involving clinical and lung function assessment. The diagnosis of asthma was made using the clinical features of asthma and lung function parameters (Forced expiratory volume in one second, Peak expiratory flow rate, Reversibility tests). Totally, 120 asthma patients participated in this study. All subjects completed the clinical asthma control questionnaires. All items were rated with the calculation of their mean and percentages. Student t-test was used to calculate the difference between the mean of the lung function tests for subjects and control. The prevalence of asthma among respiratory unit patients was 6.6% and higher in the first three decades of life with female preponderance (F:M=1.5-1).There is a strong family history of asthma(81.7%). Associated allergies include rhinitis (75%), pharyngitis (54%), conjunctivitis (54%) and dermatitis (30%). Percentage of asthma patients treated with bronchodilators alone (70%), combined inhaled bronchodilators and steroid (28.3%). Impaired daily activities include sports (84%), Job career (60%), Physical activity (55%), Social activity (54%), Household chores (61%), Disturbed sleep (53%), Daytime symptoms (51%), Hospitalized(50%). Subjects had significant low lung function values when compared with control (P < 0.05). The burden of asthma is very high despite the advanced knowledge of the pathophysiology and management of asthma.

    Diabetic dyslipidemia contributes to an increased risk of cardiovascular disease. Hence, its treatment is necessary to reduce cardiovascular events. Honey reduces hyperglycemia and dyslipidemia. The reproducibility of these beneficial effects and their generalization to honey samples of other geographical parts of the world remain controversial. Currently, data are limited and findings are inconclusive especially with evidence showing honey increased glycosylated hemoglobin in diabetic patients. It was hypothesized that this deteriorating effect might be due to administered high doses. This study investigated if Nigerian honey could ameliorate hyperglycemia and hyperlipidemia. It also evaluated if high doses of honey could worsen glucose and lipid abnormalities. Honey (1.0, 2.0 or 3.0 g/kg) was administered to diabetic rats for three weeks. Honey (1.0 or 2.0 g/kg) significantly (p < 0.05) increased high density lipoprotein (HDL) cholesterol while it significantly (p < 0.05) reduced hyperglycemia, triglycerides (TGs), very low density lipoprotein (VLDL) cholesterol, non-HDL cholesterol, coronary risk index (CRI) and cardiovascular risk index (CVRI). In contrast, honey (3.0 g/kg) significantly (p < 0.05) reduced TGs and VLDL cholesterol. This study confirms the reproducibility of glucose lowering and hypolipidemic effects of honey using Nigerian honey. However, none of the doses deteriorated hyperglycemia and dyslipidemia.

    Nowadays, an electronic health information management system (EHIMS) is crucial for patient care in hospitals. This paper explores the aspects and elements that contribute to the success of EHIMS in Nigerian teaching hospitals. The study adopted a survey research design. The population of study comprised 442 health information management personnel in five teaching hospitals that had implemented EHIMS in Nigeria. A self-developed questionnaire was used as an instrument for data collection. The findings revealed that there is a positive, close relationship between all the identified factors and EHIMS's success: technical factors (r = 0.564, P < 0.05); social factors (r = 0.616, P < 0.05); organizational factors (r = 0.621, P < 0.05); financial factors (r = 0.705, P < 0.05); and political factors (r = 0.589, P < 0.05). We conclude that consideration of all the identified factors was highly significant for the success of EHIMS in Nigerian teaching hospitals. PMID:25983557

    The fasting plasma lipid, lipoprotein and apolipoprotein profiles were determined in 14 healthy Nigerian male athletes and controls matched for sex and anthropometric parameters. The mean levels of total cholesterol (P < 0.05), low-density lipoprotein (LDL) cholesterol, apolipoprotein (apo) AII and E were significantly lower (P < 0.01) in the athletes than in the controls. However, there were no statistically significant differences (P > 0.05) between the mean values of the plasma triglycerides, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL) cholesterol, apo AI, B, Lp(a), LpA1 and CIII:NonB respectively for the athletes and controls. A priori, the potential effect on cardiovascular disease (CVD) risk was also compared using three predictor ratios - total cholesterol: HDL cholesterol (TC:HDL), LDL cholesterol: HDL cholesterol and apo B:AI. The mean of the three ratios was lower in the athletes than in the controls; however, the differences were not statistically significant (P > 0.05). Based on our data, exercise appears to decrease the TC:HDL ratio in the athletes by lowering LDL-cholesterol, while the HDL-cholesterol is unaffected. We conclude that physical activity has salutary effects on the lipid, lipoprotein and apolipoprotein profiles of healthy Nigerian men. PMID:8130968

  1. Domestic financing of communication in developing countries: a preliminary investigation of the Nigerian case.

    A case study examines the Nigerian effort to finance their communication industry. The study revealed that except during the period 1981-85, planned public investment in the communication sector has been moderately high at a level of 6.1% of aggregate ex ante expenditure. For the period 1960-80, actual communications expenditure as a ratio of actual total expenditure was lower at an average of 4.5%. Total sector performance measured by the degree of resistance to plan distortions was lower for the communication sector relative to aggregate performance through the 24-period beginning in 1962, except during the 2nd development plan period between 1970-74. The trend in domestic public financing appears to have been dictated by 2 factors: The philosophy of economic planning and the fluctuations in economic fortunes. The oil book of the mid-1970s prompted the largest planned allocation of 9% during the period 1975-80, although realized expenditure fell slightly below to a level of 7.2%. These observed trends show clearly a lack of any strong commitment by the Nigerian government for communication services to meet the needs of a significantly portion of the population, especially those in the rural areas. This situation is not likely to change soon due to the country's presently poor economy and the overemphasis by the government on market forces.

    The plant maca, grown at 4000 m altitude in the Peruvian Central Andes, contains hypocotyls that have been used as food and in traditional medicine for centuries. The aim of this research was to provide results on some health effects of oral administration of spray-dried extracts of black or red maca (Lepidium meyenii) in adult human subjects living at low (LA) and high altitude (HA). A total of 175 participants were given 3 g of either placebo, black, or red maca extract daily for 12 weeks. Primary outcomes were changes in sexual desire, mood, energy, health-related quality of life score (HRQL), and chronic mountain sickness (CMS) score, or in glycaemia, blood pressure, and hemoglobin levels. Secondary outcomes were acceptability and safety, assessed using the Likert test and side effect self-recording, respectively, and the effect of altitude. At low altitude, 32, 30, and 32 participants started the study receiving placebo, red maca, or black maca, respectively. At high altitudes, 33, 35, and 31 participants started the study receiving placebo, red maca, and black maca, respectively. Consumption of spray-dried extracts of red and black maca resulted in improvement in mood, energy, and health status, and reduced CMS score. Fatty acids and macamides were higher in spray-dried extracts of black maca than in red maca. GABA predominated in spray-dried extracts of red maca. Effects on mood, energy, and CMS score were better with red maca. Black maca and, in smaller proportions, red maca reduced hemoglobin levels only in highlanders with abnormally high hemoglobin levels; neither variety of maca reduced hemoglobin levels in lowlanders.

    Baboons are well studied in savannah but less so in more closed habitats. We investigated predation on mammals by olive baboons (Papio anubis) at a geographical and climatic outlier, Gashaka Gumti National Park (Nigeria), the wettest and most forested site so far studied. Despite abundant wildlife, meat eating was rare and selective. Over 16 years, baboons killed 7 bushbuck (Tragelaphus scriptus) and 3 red-flanked duiker (Cephalophus rufilatus), mostly still-lying 'parked' infants. Taking observation time into account, this is 1 predation per group every 3.3 months - far lower than at other sites. Some features of meat eating resemble those elsewhere; predation is opportunistic, adult males monopolize most prey, a targeted killing bite is lacking and begging or active sharing is absent. Carcass owners employ evasive tactics, as meat is often competed over, but satiated owners may tolerate others taking meat. Other features are unusual; this is only the second study site with predation records for bushbuck and the only one for red-flanked duiker. The atypical prey and rarity of eating mammals probably reflects the difficulty of acquiring prey animals when vegetation cover is dense. Our data support the general prediction of the socioecological model that environments shape behavioural patterns, while acknowledging their intraspecific or intrageneric plasticity. PMID:27287424

    OBJECTIVE: To establish the incidence and types of utero-vaginal prolapse. METHODS: Retrospective medical records analyses of women who were subjected to reconstructive pelvic surgery for various types of pelvic relaxation at the Nnamdi Azikiwe University Teaching Hospital, Nnewi and the University Of Nigeria Teaching Hospital, Enugu, Nigeria was carried out. The study was conducted from January 1996 to December 1999 during which there were 7515 surgical admissions. The inclusion criteria were those women who complained of feeling a mass in the vagina with demonAstrable descent of the anterior and/or posterior and/or apical vaginal walls and/or perineal descent. Excluded were patients who had other symptoms other than utero-vaginal prolapse and those whose grades and sites of prolapse were not determinable from the clinical or surgical notes. Also excluded were patients with nerve injury or disease, connective tissue disorders and neuromuscular diseases. The subjects were divided into two groups. Group I consisted of 54 women (age < or = 40 years), and group II included 105 women (age > or = 40 years). The findings between those two groups were compared with reference to sites, types and degree of prolapse. Also, coexistence of pelvic relaxation and underlying medical conditions were evaluated. RESULTS: A total of 159 subjects out of 492 charts studied met the inclusion criteria for the study. In group I, mean age was 32.839 with a standard deviation (SD) of +/- 6.012 years; and in group II the mean age was 56.543 with a SD of 8.094. Hypertrophic (elongated) cervix was determined in 15 (6.3%) subjects in group I for an incidence of 1.58% per year, cystocele (vaginal anterior wall descent) was present in 21 (8.9%) women for an incidence of 2.2% per year; rectocele (posterior vaginal wall descent) was identified in 15 (6.3%) women for an incidence of 1.58% per year; vaginal cough prolapse (apical descent) was present 21 (8.9%) women for an incidence of 2.2% per year

    Background: Developing countries like face dire shortage of medical manpower due to brain drain. Young doctors intending to specialize usually prefer certain specialties and sub-specialties to the neglect of others. This creates avoidable gaps in health care delivery. Aim: The aim of the following study is to determine the choices of career and reasons for those choices among young medical doctors. Subjects and Methods: A cross-sectional study of fresh interns using a pre-validated 13 item questionnaire was done at the University of Nigeria Teaching Hospital, Ituku/Ozalla, Enugu Nigeria. Results: A combination of the various surgical specialties was the most common choice made in 29/110 26.4% of the respondents. The top four specific choices were pediatrics 28/110 (25.5%), internal medicine 11/110 (10%), obstetrics and gynecology 10/110 (9.1%) and public health 8/110 (7.3%). The most common factor influencing choice of specialty was interest in 86/109 (78.9%) of the respondents. A higher proportion of males 24/69 (34.8%) compared with females 4/41 (10%) chose a specialty because of brighter prospect (P = 0.01). Conclusion: The most frequently chosen specialties by young interns were a combination of surgical specialties, internal medicine, pediatrics and obstetrics and gynecology. Interest was the most common reason for choice of specialty although males are significantly influenced by brighter prospects. PMID:25364593

    Twenty-two apparently healthy Nigerian adolescent girls aged 11-17 years residing in a hostel, were studied over five consecutive days in order to assess their energy intake (EI), energy cost of specific activities and body composition (BC). The mean characteristics of the group were: height 1.58 (SD 0.1, range 1.42-1.68) m, body weight 49.1 (SD 7.9, range 34.0-61.0) kg and BMI 19.5 (SD 2.0, range 16.0-23.0) kg/m2. The food intake of each subject was assessed by direct weighing and its energy value was determined by means of a ballistic bomb calorimeter. BMR values were calculated according to Food and Agriculture Organization/World Health Organization/United Nations University (FAO/WHO/UNU) (1985) equations. Percentage body fat (BF%) values were derived from three skinfold thickness measurements, using population-specific equations. The adolescents' mean daily EI was found to be 6510 (SD 855) kJ/d (138.3 (SD 27.8) kJ/kg body weight per d) which is lower than the FAO/WHO/UNU (1985) calculated energy requirement of 8800 kJ/d for adolescent girls aged 12-14 years. The contributions of specific nutrients and individual meals to the total EI were: carbohydrate, protein and fat, 59.2, 12.5 and 28.3% of energy respectively and breakfast, lunch and supper, 21.5, 41.0 and 37.4% respectively. However, the mean BMR was 5627 kJ/d, which is comparable with that given by FAO/WHO/UNU (1985) for adolescent girls aged 13-14 years. The mean BF% was found to be 21.7. The comparatively low EI of the participants in the present study may be indicative of energy deficiency in their meals. This assumption is also reflected in their BC values. Nevertheless, further studies of this kind on adolescents in Nigeria are needed to confirm these observations. PMID:9155501

    This work describes our on-going investigations on the study of uptake of zinc from dietary intakes, into blood. The aim is to evaluate the possibility of successful application of dietary zinc therapy in the management of Sickle Cell Anaemia (SCA). Seven adult subjects were involved in the current study. After the ingestion of an experimental diet, blood samples were withdrawn from the subjects at various time intervals. The blood samples were further separated into erythrocytes and plasma. Both blood components and the ingested diet were analysed by instrumental neutron activation analysis (INAA) for zinc. Significant increases in the levels of plasma zinc were recorded in the subjects within 2 hours after the ingestion of the diet and were sustained till about the fourth hour. We were not able to detect significant uptake of zinc in the erythrocytes. Either the levels of ingested zinc were too low or there were inhibitions of the absorption by the diet. Better response is expected in SCA patients since they are known to be frequently zinc-deficient.

    We report a 38-year-old Nigerian woman with sickle cell disease. Sickle cell disease had been diagnosed when she experienced her first sickle cell crisis episode at age 8 years. Thereafter, she had infrequent minor episodes. She visited a hospital presenting with fever, anemia, jaundice, and systemic pain, and was then transferred to our hospital. Together with rehydration and red blood cell transfusion, analgesics and antibiotics were prescribed, and produced gradual improvement of all symptoms and signs. The patient was discharged on day 9 of hospitalization. Sickle cell crisis is an acute painful episode caused by occlusion of arterioles. The degree of pain and accompanying symptoms, as well as the frequencies of crises, are variable. Moreover, one third of individuals with sickle cell disease never experience a crisis. As our society becomes increasingly globalized, the probabilities of encountering sickle cell disease patients will be higher. PMID:25745965

    The concepts of distance, area, and the coordinate reference systems were investigated in relation to the displacement volume task among 300 randomly selected primary and high school children in Nigeria. Piaget and Inhelder (1971) theorized a developmental progression in the acquisition of these concepts among Genevan children, and a number of studies have confirmed pancultural stability in the acquisition of these concepts. Four tasks were used to investigate the acquistion of these concepts developmentally, and the data obtained were analyzed by the chi-square, Pearson correlation coefficient and the 50% success criterion suggested by Laurendea and Pinard (1962, 1970). The data confirmed Piaget's theorizing but when compared with similar studies in Europe and America (Lovell (1971), Dasen (1972), & Karplus et al. (1977), a developmental lag of about two years was observed among the Nigerian Ss. The concept of horizontal decalages was discussed in relation to the data including some implications for science teaching particularly in developing countries.

    Despite a rising prevalence worldwide, there is limited data on pregnancy outcome among African women with prepregnancy or early pregnancy obesity. This was a case-control study to determine the prevalence of maternal obesity in early pregnancy and compare the subsequent pregnancy outcome between 201 women with obesity and 201 non-obese controls in a University Teaching Hospital in Nigeria. The prevalence of obesity in early pregnancy was 9.63%. Obesity was significantly associated with advanced maternal age and parity > or =1. It was also a risk factor for pregnancy induced hypertension, admissions during pregnancy, caesarean delivery and associated with 5th minute apgar score < or =3 (0.044). Obesity in early pregnancy is a risk factor for adverse pregnancy outcome among pregnant Nigerian women. This information should be utilised by physicians to improve the outcome of pregnancy and promote safe motherhood.

    Tuberculous mastitis is an uncommon disease even in countries where tuberculosis is highly endemic. It typically presents a diagnostic challenge masquerading as carcinoma or other primary disease of the breast. We report the case of a young multiparous Nigerian woman who presented with a tender left breast lump and enlargement of the left axillary lymph nodes for which a provisional diagnosis of carcinoma of the breast was made after clinical and radiological evaluation. The mass was pathologically diagnosed as tuberculous mastitis and anti-tuberculous therapy was instituted although she later absconded. This case shows that TM may present a diagnostic challenge on clinical, radiologic and microbiological investigation. Therefore, a high index of suspicion as well as FNAC and/or histological evaluation of tissue samples remain very important its diagnosis.

    This study reviewed the youth restiveness in Niger Delta rural areas as lesson for the contemporary Nigerian society. The study was based on secondary sources of information. The study identified youths in the area as people between the ages of 15 ñ 40 years. Youths possess viable characteristics for rural development which if mismanaged results into restiveness. The study showed that the primary causes of youth restiveness in the area were proliferation of arms, misuse of the military to suppress protests, misappropriation of benefits from crude oil, youth unemployment and environmental degradation. Consequences of youth restiveness among others included loss of life and properties, rural-urban migration of the farm families, breeding defective future leaders, disruption of oil and gas activities and food insecurity. In order to eradicate youth restiveness, the contemporary Nigeria society should check the rate of arm proliferation, misuse of the military to suppress youth protests, misappropriation of benefits accruing to the communities, youth unemployment and environmental degradation.

    Using a structured pro forma, 728 out of 775 medical undergraduates at a Nigerian university were surveyed for the prevalence and pattern of drug use. An operational definition of substance abuse was made, and 28 percent of students fell within that criterion. Male abusers (81 percent) exceeded female abusers (19 percent). Substances most commonly abused were alcohol (60 percent), minor tranquilizers (48 percent), tobacco (35 percent), and narcotics (29 percent), particularly codeine. Only 11 percent abused cannabis. While most students were polydrug users, there was a low frequency of daily drug use. A general lifetime (occasional use) prevalence of substance use of 56 percent was found. Drugs consumed on a daily basis were alcohol (2 percent) and tobacco (6 percent). The prevalence of drug use was highest among the fourth and final year students. The majority of students were occasional abusers; there was no evidence of physical dependence. PMID:3257527

    The relationship between nutritional status and umbilical hernia was assessed among Hausa and Yoruba school children in rural areas of Kwara State, Nigeria. The prevalence of umbilical hernia in the rural school pupils was 19.4%. The Yoruba school children had a higher prevalence rate of 22.0%, while the prevalence rate for Hausa pupils was 16.9%. The association between umbilical hernia and primary school class was statistically significant. More school children suffering from protein energy malnutrition presented with umbilical hernia. The association between umbilical hernia and nutritional status was weak. The school health component of the national primary health program should be intensified to screen school children regularly for umbilical hernia. The school health environment of rural Nigerian schools should be improved through government efforts. Images Figure 1 Figure 2 PMID:1800766

    The Udu drum, sometimes called the water pot drum, is a traditional Nigerian instrument. Musicians who play the Udu exploit its aerophone and idiophone resonances. This paper will discuss an electrical equivalent circuit model for the Udu Utar, a modern innovation of the traditional Udu, to predict the low frequency aerophone resonances and will also present scanning laser vibrometer measurements to determine the mode shapes of the dominant idiophone resonances. These analyses not only provide an understanding of the unique sound of the Udu instrument but may also be used by instrument designers to create instruments with resonance frequencies at traditional musical intervals for the various tones produced and to create musical harmonic ratios. The information, specifically the laser vibrometry measurements, may also be useful to musicians in knowing the best places to strike the Udu to excite musical tones.

    Abstract Sub-Saharan Africa is currently undergoing an epidemiological transition from a disease burden largely attributable to communicable diseases to that resulting from a combination of both communicable and chronic non-communicable diseases. Data on chronic disease incidence, lifestyle, environmental and genetic risk factors are sparse in this region. This report aimed at providing relevant information in respect to risk factors that increase blood pressure and lead to development of intermediate cardiovascular phenotypes. We presented the rationale, objectives and key methodological features of the Nigerian Population Research on Environment, Gene and Health (NIPREGH) study. The challenges encountered in carrying out population study in this part of the world and the approaches at surmounting them were also presented. The preliminary data as at 20 November 2013 showed that out of the 205 individuals invited starting from early April 2013, 160 (72 women) consented and were enrolled; giving a response rate of 78%. Participants' age ranged from 18 to 80 years, with a mean (SD) of 39.8 (12.4) years and they were of 34 different ethnic groups spread over 24 states out of the 36 states that constitute Nigeria. The mean (SD) of office and home blood pressures were 113.0 (15.2) mm Hg systolic, 73.5 (12.5) mm Hg diastolic and 117.3 (15.0) mm Hg systolic, and 76.0 (9.6) mm Hg diastolic, respectively. Forty-three (26.8%) participants were hypertensive and 8 (5.0%) were diabetic. In addition to having the unique potential of recruiting a cohort that is a true representative of the entire Nigerian population, NIPREGH is feasible and the objectives realisable. PMID:25332707

    Elevated plasma lipoprotein (a) (Lp(a)) and total homocysteine (tHcy) concentrations, as well as fat distributions, are associated with cardiovascular disease (CVD) risk. The purpose of this study was to evaluate plasma Lp(a), tHcy, percentage body fat, anthropometric indices, and blood pressure (BP) and their relationships with each other in well-defined, hospital-based, CVD patients in a Nigerian African community. One hundred seventy patients suffering from hypertensive heart disease, hypertension, ischaemic heart disease, and myocardial infraction with the mean age of 45.3 +/- 1.3 years and 58 apparently healthy volunteers with the mean age of 44.8 +/-1.2 years were selected. Anthropometric indices and BP were measured. Percentage body fat, body mass index, and waist-to-hip ratio (WHR) were calculated. Plasma Lp(a) and tHcy concentrations were determined. The results showed significant increases in BP, skinfold thickness (SFT) variables, and WHR in all of the CVD patients. Plasma Lp(a) was also significantly increased (p < 0.001), whereas the slight increase in the mean tHcy was not statistically significant. Positive significant correlations were found between systolic BP, triceps, SFT, and percentage body fat (p < 0.01), whereas significant correlations were found between some body composition variables, tHcy, and systolic BP (p < 0.05). Our findings provide supportive evidence for altered plasma Lp(a) concentration in addition to some other traditional CVD risk factors in Nigerians. The role of homocysteine is not well defined.

    Decentralizing health services, including those for HIV prevention and treatment, is one strategy for maximizing the use of limited resources and expanding treatment options; yet few methods exist for systematically identifying where investments for service expansion might be most effective, in terms of meeting needs and rapid availability of improved services. The Nigerian Government, the United States Government under the President's Emergency Plan for AIDS Relief (PEPFAR) program and other donors are expanding services for prevention of mother-to-child transmission (PMTCT) of HIV to primary health care facilities in Nigeria. Nigerian primary care facilities vary greatly in their readiness to deliver HIV/AIDS services. In 2012, MEASURE Evaluation assessed 268 PEPFAR-supported primary health care facilities in Nigeria and developed a systematic method for prioritizing these facilities for expansion of PMTCT services. Each assessed facility was scored based on two indices with multiple, weighted variables: one measured facility readiness to provide PMTCT services, the other measured local need for the services and feasibility of expansion. These two scores were compiled and the summary score used as the basis for prioritizing facilities for PMTCT service expansion. The rationale was that using need and readiness to identify where to expand PMTCT services would result in more efficient allocation of resources. A review of the results showed that the indices achieved the desired effect—that is prioritizing facilities with high need even when readiness was problematic and also prioritizing facilities where rapid scale-up was feasible. This article describes the development of the two-part index and discusses advantages of using this approach when planning service expansion. The authors' objective is to contribute to development of methodologies for prioritizing investments in HIV, as well as other public health arenas, that should improve cost-effectiveness and

    Nutritional rickets in Nigerian children usually results from dietary calcium insufficiency. Typical dietary calcium intakes in African children are about 200mg daily (approximately 20-28% of US RDAs for age). We sought to determine if rickets could be prevented with supplemental calcium or with an indigenous food rich in calcium. We enrolled Nigerian children aged 12 to 18months from three urban communities. Two communities were assigned calcium, either as calcium carbonate (400mg) or ground fish (529±109mg) daily, while children in all three communities received vitamin A (2500IU) daily as placebo. Serum markers of mineral homeostasis and forearm bone density (pDEXA) were measured and radiographs were obtained at enrollment and after 18months of supplementation. The overall prevalence of radiographic rickets at baseline was 1.2% and of vitamin D deficiency [serum 25(OH)D<12ng/ml] 5.4%. Of 647 children enrolled, 390 completed the 18-month follow-up. Rickets developed in 1, 1, and 2 children assigned to the calcium tablet, ground fish, and control groups, respectively (approximate incidence 6.4/1000 children/year between 1 and 3years of age). Children who developed rickets in the calcium-supplemented groups had less than 50% adherence. Compared with the group that received no calcium supplementation, the groups that received calcium had a greater increase in areal bone density of the distal and proximal 1/3 radius and ulna over time (P<0.04). We conclude that calcium supplementation increased areal bone density at the radius and ulna, but a larger sample size would be required to determine its effect on the incidence of rickets.

    OBJECTIVES The advent of the tyrosine kinase inhibitors has markedly changed the prognostic outlook for patients with Ph+ and/or BCR-ABL1+ chronic myeloid leukemia (CML). This study was designed to assess the overall survival (OS) of Nigerian patients with CML receiving imatinib therapy and to identify the significant predictors of OS. METHODS All patients with CML receiving imatinib from July 2003 to June 2013 were studied. The clinical and hematological parameters were studied. The Kaplan–Meier technique was used to estimate the OS and median survival. P-value of <0.05 was considered as statistically significant. RESULTS The median age of all 527 patients (male/female = 320/207) was 37 (range 10–87) years. There were 472, 47, and 7 in chronic phase (CP), accelerated phase, and blastic phase, respectively. As at June 2013, 442 patients are alive. The median survival was 105.7 months (95% confidence interval [CI], 91.5–119.9); while OS at one, two, and five years were 95%, 90%, and 75%, respectively. Multivariate Cox regression analysis revealed that OS was significantly better in patients diagnosed with CP (P = 0.001, odds ratio = 1.576, 95% CI = 1.205–2.061) or not in patients with anemia (P = 0.031, odds ratio = 1.666, 95% CI = 1.047–2.649). Combining these variables yielded three prognostic groups: CP without anemia, CP with anemia, and non-CP, with significantly different median OS of 123.3, 92.0, and 74.7 months, respectively (χ2 = 22.042, P = 0.000016). CONCLUSION This study has clearly shown that for Nigerian patients with CML, the clinical phase of the disease at diagnosis and the hematocrit can be used to stratify patients into low, intermediate, and high risk groups.

    BACKGROUND Interdisciplinary collaboration in the management of patients offers several advantages especially for children with chronic illnesses who are often at risk for other health conditions. Diseases in other parts of the body can be detected by a physician and lead to subsequent referral to the appropriate managing team. This study assessed the perception and experience of dental referral among Nigerian paediatricians as well as factors that may influence their decision to refer to a dentist. METHODS Self administered questionnaires were used to obtain socio-demographic data, history of exposure to dental teachings as well as experience with dental referral. Two hundred and sixty nine paediatricians and paediatric practitioners were involved in the study. Descriptive statistics and measures of central tendencies generated. Associations were tested with Chi Squares and Statistical significance was set at P <0.05 RESULTS A total of 269 respondents participated in the study out of whom 142(52.8%) trained at institutions where there was a sister dental school, but 243(90.3%) of them had no official dentistry postings. Majority of the respondents 259(96.3%) were in favour of routine professional oral check-up for children but only 83(30.9%) endorsed the recommended bi annual oral checks. A referral rate of 0.76-1.9% was obtained. CONCLUSION Although paediatricians are a known source of dental referral for children globally, a lot needs to be done to equip the physicians with the necessary knowledge and skill that will enable them participate more actively in the promotion of oral health for Nigerian children.

    Abstract Objective To rank pollutants in two Nigerian water supply schemes according to their effect on human health using a risk-based approach. Methods Hazardous pollutants in drinking-water in the study area were identified from a literature search and selected pollutants were monitored from April 2010 to December 2011 in catchments, treatment works and consumer taps. The disease burden due to each pollutant was estimated in disability-adjusted life years (DALYs) using data on the pollutant’s concentration, exposure to the pollutant, the severity of its health effects and the consumer population. Findings The pollutants identified were microbial organisms, cadmium, cobalt, chromium, copper, iron, manganese, nickel, lead and zinc. All were detected in the catchments but only cadmium, cobalt, chromium, manganese and lead exceeded World Health Organization (WHO) guideline values after water treatment. Post-treatment contamination was observed. The estimated disease burden was greatest for chromium in both schemes, followed in decreasing order by cadmium, lead, manganese and cobalt. The total disease burden of all pollutants in the two schemes was 46 000 and 9500 DALYs per year or 0.14 and 0.088 DALYs per person per year, respectively, much higher than the WHO reference level of 1 × 10−6 DALYs per person per year. For each metal, the disease burden exceeded the reference level and was comparable with that due to microbial contamination reported elsewhere in Africa. Conclusion The estimated disease burden of metal contamination of two Nigerian water supply systems was high. It could best be reduced by protection of water catchment and pretreatment by electrocoagulation. PMID:23940402

    This study aimed at assessing qualitatively and quantitatively the ability of Nigerian mothers to prepare salt-sugar solutions (SSS) (according to the Nigerian standard formula) under the usual home environment. Mothers were provided with the ingredients but not with measurement spoons nor containers. 274 mothers randomly selected from a peri-urban community participated in the study. Of the 192 (70.1%) who claimed knowledge on SSS preparation, only 47 (24.5%) gave a correct description of its constitution and 103 (54.2%) were willing to prepare the solution. Of the 103 who prepared the solution, 34 (33.0%) used the correct number of teaspoons of salt and of sugar. The composition of the solutions prepared by the mothers varied greatly with sodium levels ranging from 0-760 mmols/l (mean 225.8 +/- 155.3, median 177.3) and glucose, 0-262.6 mmols/l (mean 68.7 +/- 54.4, median 52.0). Only 7 mothers (6.8%) prepared solutions with acceptable sodium and glucose levels. It is concluded that salt-sugar solutions prepared by Nigerian mothers are not safe. There is a great need to review the oral rehydration therapy (ORT) promotion strategies and messages in order to avoid the dangers associated with improperly constituted solutions. PMID:8230075

    In recent years Nigeria has experienced sporadic incursions of highly pathogenic H5N1 avian influenza among poultry. In 2008, 316 poultry-exposed agricultural workers, and 54 age-group matched non-poultry exposed adults living in the Enugu or Ebonyi States of Nigeria were enrolled and then contacted monthly for 24 months to identify acute influenza-like-illnesses. Annual follow-up sera and questionnaire data were collected at 12 and 24 months. Participants reporting influenza-like illness completed additional questionnaires, and provided nasal and pharyngeal swabs and acute and convalescent sera. Swab and sera specimens were studied for evidence of influenza A virus infection. Sera were examined for elevated antibodies against 12 avian influenza viruses by microneutralization and 3 human viruses by hemagglutination inhibition. Four (3.2%) of the 124 acute influenza-like-illness investigations yielded molecular evidence of influenza, but virus could not be cultured. Serial serum samples from five poultry-exposed subjects had a ≥4-fold change in microneutralization titers against A/CK/Nigeria/07/1132123(H5N1), with three of those having titers ≥1:80 (maximum 1:1,280). Three of the five subjects (60%) reported a preceding influenza-like illness. Hemagglutination inhibition titers were ≥4-fold increases against one of the human viruses in 260 participants. While cross-reactivity from antibodies against other influenza viruses cannot be ruled out as a partial confounder, over the course of the 2-year follow-up, at least 3 of 316 (0.9%) poultry-exposed subjects had evidence for subclinical HPAI H5N1 infections. If these data represent true infections, it seems imperative to increase monitoring for avian influenza among Nigeria's poultry and poultry workers.

    Innovative developments are necessary for treating and defeating cancer, an oftentimes deadly group of diseases characterized by the uncontrolled growth and spread of abnormal cells. Breast cancer (BC) is the second leading cause of cancer-related deaths of women in the USA, and prostate cancer (PC) is the second leading cause of cancer-related deaths of American men. Although some efficacious BC drugs are pharmaceutically marketed, they affect the quality of life for some patients because they are toxic in that their usages have been accompanied by side effects such as stroke, thrombosis, slow heart rate, seizure, increased blood pressure, nausea, emesis, and more. Therefore, there is an urgent need for the discovery of molecular markers for early detection of this disease and discovery of targets for the development of novel, less toxic therapeutics. A botanical plant Vernonia amygdalina has been widely used in Nigerian and other Central and West African cultures for centuries as an herbal medicine. Mounting evidence suggests that treatment with low concentrations of aqueous leaf extracts of the edible Nigerian V. amygdalina plant (Niger-VA) arrests the proliferative activities and induces apoptosis in estrogen receptor-positive, estrogen receptor-negative, and triple-negative human breast cancerous cells and in androgen-independent human PC-3. Also, in athymic mice, Niger-VA potentiates increased efficacies and optimizes treatment outcomes when given as a cotreatment with conventional chemotherapy drugs. Evidence of its noticeable cytostatic activities ranging from changes in DNA synthesis to growth inhibition, mechanisms of inducing apoptosis in different cancer cell lines, and in vivo antitumorigenic activities and chemopreventive efficacy reinforce the idea that Niger-VA deserves increased attention for further development as a phytoceutical, anticancer drug entity. Hence, the present review article highlights impactful published literature on the anticancer

    Background The epidemic of HIV continues to grow in Nigeria. Personnel in the military are at increased risk of HIV infection. Although HIV-risk related sexual behavior of Nigerian police officers has been studied, little is known about the sexual behavior of their counterparts in the Navy. This study describes knowledge of AIDS, and HIV-risk sexual behavior of naval personnel in Lagos Nigeria. Methods Four hundred and eighty personnel of the Nigerian Navy completed a 70-item questionnaire in 2002. Group discussion and in-depth interviews of four key informants were also conducted to gain insights into the context of risky sexual behaviors and suggestions for feasible HIV primary prevention interventions. Results The mean age of the respondents was 34 years. Although the overall mean AIDS knowledge score was 7.1 of 10 points, 52.1% of respondents believed that a cure for AIDS was available in Nigeria and that one can get HIV by sharing personal items with an infected person (25.3%). The majority (88.1%) had had lifetime multiple partners ranging from 1–40 with a mean of 5.1; 32.5% of male respondents had had sexual contact with a female sex worker, 19.9% did so during the six months preceding the survey. Forty-one percent of those with sexual contact with a female sex worker did not use a condom during the most recent sexual encounter with these women. Naval personnel who have been transferred abroad reported significantly more risky sexual behaviors than others. Group discussants and key informants believed that sex with multiple partners is a tradition that has persisted in the navy even in the era of AIDS because of the belief that AIDS affects only foreigners, that use of traditional medicine provides protection against HIV infection, and influence of alcohol. Conclusion Many naval personnel report participating in high-risk sexual behavior which may increase their risk of acquiring and spreading HIV. Naval personnel live and interact freely with civilian

  17. Adult flatfoot.

    Adult flatfoot is defined as a flattening of the medial arch of the foot in weight-bearing and lack of a propulsive gait. The 3 lesion levels are the talonavicular, tibiotarsal and midfoot joints. The subtalar joint is damaged by the consequent rotational defects. Clinical examination determines deformity and reducibility, and assesses any posterior tibialis muscle deficit, the posterior tibialis tendon and spring ligament being frequently subject to degenerative lesions. Radiographic examination in 3 incidences in weight-bearing is essential, to determine the principal level of deformity. Tendon (posterior tibialis tendon) and ligamentous lesions (spring ligament and interosseous ligament) are analyzed on MRI or ultrasound. In fixed deformities, CT explores for arthritic evolution or specific etiologies. 3D CT reconstruction can analyze bone and joint morphology and contribute to the planning of any osteotomy. Medical management associates insoles and physiotherapy. Acute painful flatfoot requires strict cast immobilization. Surgical treatment associates numerous combinations of procedures, currently under assessment for supple flatfoot: for the hindfoot: medial slide calcaneal osteotomy, calcaneal lengthening osteotomy, or arthroereisis; for the midfoot: arthrodesis on one or several rays, or first cuneiform or first metatarsal osteotomy; for the ankle: medial collateral ligament repair with tendon transfer. Fixed deformities require arthrodesis of one or several joint-lines in the hindfoot; for the ankle, total replacement after realignment of the foot, or tibiotalocalcaneal fusion or ankle and hindfoot fusion; and, for the midfoot, cuneonavicular or cuneometatarsal fusion. Tendinous procedures are often associated. Specific etiologies may need individualized procedures. In conclusion, adult flatfoot tends to be diagnosed and managed too late, with consequent impact on the ankle, the management of which is complex and poorly codified.

    Which competences do professional adult educators need? This research note discusses the topic from a comparative perspective, finding that adult educators' required competences are wide-ranging, heterogeneous and complex. They are subject to context in terms of national and cultural environment as well as the kind of adult education concerned (e.g. basic education, work-related education etc.). However, it seems that it is possible to identify certain competence requirements which transcend national, cultural and functional boundaries. This research note summarises these common or "core" requirements, organising them into four thematic subcategories: (1) communicating subject knowledge; (2) taking students' prior learning into account; (3) supporting a learning environment; and (4) the adult educator's reflection on his or her own performance. At the end of his analysis of different competence profiles, the author notes that adult educators' ability to train adult learners in a way which then enables them to apply and use what they have learned in practice (thus performing knowledge transfer) still seems to be overlooked.

    Fatty acids esters were produced from two Nigerian lauric oils, palm kernel oil and coconut oil, by transesterification of the oils with different alcohols using PS30 lipase as a catalyst. In the conversion of palm kernel oil to alkyl esters (biodiesel), ethanol gave the highest conversion of 72%, t-butanol 62%, 1-butanol 42%, n-propanol 42% and iso-propanol 24%, while only 15% methyl ester was observed with methanol. With coconut oil, 1-butanol and iso-butanol achieved 40% conversion, 1-propanol 16% and ethanol 35%, while only traces of methyl esters were observed using methanol. Studies on some fuel properties of palm kernel oil and its biodiesel showed that palm kernel oil had a viscosity of 32.40 mm2/s, a cloud point of 28 degrees C and a pour point of 22 degrees C, while its biodiesel fuel had a viscosity of 9.33 mm2/s, a cloud point of 12 degrees C and a pour point of 8 degrees C. Coconut oil had a viscosity of 28.58 mm(2)/s, a cloud point of 27 degrees C and a pour point of 20 degrees C, while its biodiesel fuel had a viscosity of 7.34 mm2/s, a cloud point of 5 degrees C and a pour point of -8 degrees C. Some of the fuel properties compared favourably with international biodiesel specifications.

    Background: Smokeless and cigarette tobacco use is becoming increasingly popular among Nigerian adolescents. This study aimed to evaluate predictors of intention to quit tobacco use among adolescents that currently use tobacco products in Nigeria. Materials and Methods: A total of 536 male and female high school students in senior classes in Benue State, Nigeria were enrolled into the cross-sectional study. The survey instrument was adapted from the Global Youth Tobacco Survey (GYTS) questionnaire. Results: Among adolescents with tobacco habits, 80.5% of smokeless tobacco users and 82.8% of cigarette smokers intended to quit tobacco use within 12 months. After adjustment, significant predictors of intention to quit cigarette smoking were parents’ smoking status (P<0.01), peers’ smokeless use status (P<0.01) and perception that smoking made one comfortable at social events (P<0.01). For intention to quit smokeless tobacco use, significant predictors after adjustment were parents’ smokeless use status, (P=0.03) perception that smokeless tobacco use made one more comfortable at social events (P=0.04) and perception of harm from smokeless use (P=0.02). Conclusion: This study demonstrates that the intention to quit smokeless and cigarette tobacco use is significantly predicted by perception about the societal acceptance of tobacco use at social events, parents and peers’ tobacco use status as well as the perception of harm from use of tobacco products. Providing social support may increase quit attempts among youth smokers. PMID:23271842

    Machado-Joseph disease (MJD) has been described in Africans, but no cases have been reported from Nigeria. Current MJD global distribution results from both the ancestral populations-of-origin and the founder effects of mutations, some as a consequence of the Portuguese sea travels in the 15th to 16th century. Two main ancestral haplotypes have been identified: the Machado lineage, which is more recent, predominant in families of Portuguese extraction, and the Joseph lineage, which is much older and worldwide spread, postulated to have an Asian origin. We report a Nigerian family with MJD from Calabar, once settled by Portuguese slave traders, and assessed its mutational origin. The proband was a 33-year-old man with progressive unsteady gait, weakness of all limbs, dysphagia, dysarthria, urinary frequency and diaphoresis. He had end-of-gaze nystagmus, spastic quadriparesis and atrophic small muscles of the hand. He showed fibrillation potentials on EMG, and nerve conduction studies suggested a central axonopathy without demyelination. This family bears the Joseph haplotype, which has a founder effect in the island of Flores, in the Azores (and their descendants in North-America), but is also the most common in non-Portuguese populations worldwide, with an estimated mutation age of around 7000 years.

    Eggs of the lung fluke genus Paragonimus were detected in red-capped mangabeys (Cercocebus torquatus) in Nigeria. We assess the role of these primates as potential sylvatic hosts and the clinical effects of the parasite on monkeys. DNA sequenced from eggs in feces were 100% identical in the ITS2 region to Paragonimus africanus sequences from humans in Cameroon. Paragonimus-positive monkeys coughed more than uninfected monkeys. Experimental de-worming led to reduction in parasite intensity and a corresponding reduction of coughing to baseline levels in infected monkeys. This report provides the first evidence of Paragonimus sp. in C. torquatus, of P. africanus in Nigerian wildlife, and the first molecular evidence of the parasite in African wildlife. Coughing, sometimes interpreted as a communication behavior in primates, can actually indicate infection with lung parasites. Observations of coughing in primates may, in turn, provide a useful mechanism for surveillance of Paragonimus spp, which are re-emerging human pathogens, in wildlife reservoirs. PMID:26543803

    The impact of integration of both data and disciplines is presented in the case of an Nigerian field, with particular emphasis on the central role of seismic data: A pre-requisite for any seismic interpretation is a reliable well-to-seismic tie. Due to log data availability and quality, this match was only achieved by generating synthetic seismograms based on acoustic impedance models. The seismic time interpretation was guided by the geological framework following sequence stratigraphical principles. Depth conversion and evaluation of volumetric uncertainties were based on all data. The resulting STOIIP estimates have been compared to the volumes derived independently from production data. It then became possible to explain apparent mismatches seen in some reservoirs by modifying the best-estimate volumes within the uncertainties and by comparison with analogue reservoirs Channel-like amplitude features encountered in shallow reservoirs helped to explain variable production performance and consequently to identify appraisal and development opportunities. Some of the deeper, shoreface sands seem to behave in a more tank-like manner. This is not only confirmed by recent RST-logs, but also by seismic flatspots. The flatspots are conformable to structure and reflect the remaining oil distribution. These results highlight the value of continuous integration of data and disciplines to the petroleum engineering study.

    The study analyzes the factors influencing conduct of HIV test and risky behavour change using the health belief model. The data were obtained from the Nigeria's 2004 NLSS data and analyzed with descriptive statistics and Probit regression. Results show that 87.79% of the single youths were aware of HIV/AIDS, 3.34% conducted HIV test and 71.73% desisted from risky behaviour by having sex with one partner (24.35%), not starting sex (16.90%) and using condom (14.29%). Also, probability of conducting HIV test and changing risky behaviours significantly increases (p<0.10) with age, access to radio, television and per capita expenditure, while it significantly decreases with no formal education. Residence in urban area significantly increases probability of conducting HIV test, but significantly reduces probability of changing risky behaviours. The study recommends integration of health studies into Nigerian elementary school curriculums, provision of adequate facilities for free HIV test in rural areas, among others. PMID:21243920

    A total of 970 eggs were collected from matings involving three genotypes of Nigerian local chickens (Normal-feathered, Frizzle-feathered and Naked neck) and one exotic broiler breeder strain (Anak Titan) to evaluate the effect of crossbreeding on fertility, hatchability and embryonic mortality. Mating was achieved through artificial insemination. Sire genotype significantly (P < 0.05) affected percent fertility and percent dead-in-shell. Naked neck sire genotype had the highest dead-in-shell (19.5%) with the least being 7.5% for Frizzle-feathered chickens. Frizzle-feathered sire genotype had the highest fertility (90.5%) and hatchability (91.4%). Dam genotype had a significant effect (P < 0.01) on fertility and hatchability, with Anak Titan dam having the highest fertility and hatchability of 88.2% and 94.6%, respectively. Fertility and hatchability were significantly (P < 0.05) influenced by the interactive effect of sire and dam genotypes with Frizzle-feathered × Anak Titan having 98.5% fertility and 96.8% hatchability. Both straight and reciprocal crosses involving Frizzle-feathered genotype and Anak Titan resulted in higher mean values for fertility and hatchability when compared to crosses involving the other two local chicken genotypes. This result suggests that the use of the Frizzle-feathered genotype appears to be more desirable in fertility and hatchability trials. PMID:21786049

    Objective: The study was to appraise the level of expertise in the management of Naso-Orbito-Ethmoid (NOE) fractures and to provide recommendation for necessary improvement in an African population. Materials and Methods: A questionnaire was designed and electronically mailed to Nigerian Oral & Maxillofacial surgeons, Plastic and Reconstructive surgeons, and Ear, Nose and Throat surgeons to assess their perspectives and practices in the diagnosis and management of NOE fractures. Further administration of questionnaire was done at the AO (Association of Osteosynthesis) principle course in Lagos, January, 2010. Information generated were coded and processed with statistical package for Social Sciences version 15.0, Chicago Illinois, USA. Results: The questionnaire was delivered to 214 surgeons, there were 112 respondents out of which 78 expressed no interest in the management of NOE fractures and 34 had interest and so completed the questionnaire. Diagnosis is largely based on plain radiographs; only 22 surgeons perform NOE trauma surgery, majority (63.9%) use existing laceration or more conservative approaches like Lynch or open sky incisions. Mini and micro-plates are employed by only 31.8% of the surgeons. Bone grafting is rarely performed but when required, the iliac crest is preferred. Repair of the nasolacrimal duct system is rarely done. Conclusion: The management of NOE fractures in Nigeria, falls short of the current best evidence in the world literature. International collaboration for improvement is recommended. PMID:25161412

    Petroleum prospecting and producing activities have been going on in the Niger Delta area of Nigeria for about 40 years. During this period controlled substances such as chemicals and radioactive materials have been widely used in petroleum exploration and exploitation. Deviations from acceptable levels of certain parameters relevant to safety and environmental protection have been encountered, but most have not been investigated or documented. In particular, cases involving the unsafe use, loss and abandonment of radioactive materials have neither received the desired attention nor been reported. This work reports a radiological assessment of safety in the use of radioactive and radiation producing materials in logging and well study operations in the Nigerian petroleum industry. The assessment protocol used for the evaluation is based on a numerical ranking system. Based on a scale of 100, it is found in this logging and well study that the level of safety as defined in the text is around 60% for all three sites assessed. There is substantial work needed to raise the radiation protection standards further at these sites.

    This study used data on currently married and cohabiting men aged 15 to 64 years from the 2003 Nigeria Demographic and Health Survey to examine the prevalence of and factors associated with extramarital sex. The results show that 16% engaged in extramarital sex in the 12 months preceding the survey and had an average of 1.82 partners. The results also show statistically significant association between extramarital sex and ethnicity, religion, age, age at sexual debut, education, occupation, and place of residence. Based on the study results, it could be concluded that significant proportions of Nigerians are exposed to HIV infection through extramarital sex. A fundamental behavioral change expected in the era of HIV/AIDS is the inculcation of marital fidelity and emotional bonding between marital partners. The promotion of condom use among married couples should be intensified to protect women, a large number of whom are exposed to HIV infection from their spouses who engage in unprotected extramarital sex. And, because of gender-based power imbalances within the family, a large number of the women are unable to negotiate consistent condom use by their partners.

    Food and drinking water are poorly delineated sources of human exposure to chemical food mutagens and endocrine-disrupting chemicals. In this study, we investigated the presence of mutagens and chemicals exhibiting estrogenic activity in the daily diet of Nigerians, using in vitro assays. Commercially processed foods or snacks and various brands of pure water sachets were extracted by solid-phase extraction and liquid-liquid extraction, respectively. Mutagenicity was determined by the conventional Ames test and two complementary assays on two strains of Salmonella (TA 100 and TA 98), while the estrogenic activity was assessed by a yeast bioluminescent assay, using two recombinant yeast strains (Saccharomyces cerevisiae BMAEREluc/ERα and S. cerevisiae BMA64/luc). A third of the food varieties investigated (chin-chin, hamburger, suya and bean cake) were mutagenic in all three assays, either in the presence or absence of S9 mix. Of the packed water samples, five out of the sixteen investigated (31%), were found to be estrogenic, with estradiol and bisphenol A equivalents ranging from 0.79 to 44.0 ng/L and 124.2 to 1,000.8 ng/L, respectively. Hence, although the current situation in Nigeria does not appear to be substantially worse than, e.g., in Europe, regular monitoring is warranted in the future. PMID:25153465

    Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma. PMID:26550522

    1994-06-01

    Questionnaires completed by 45 female employees from 8 broadcast stations in Nigeria revealed that, despite some growth in female employment in areas such as programming, the status of women in this sector reproduces women's subordinate status in the broader society. For every 1 woman employed in the state radio stations and state and federal television stations represented in the survey, there were 7 male employees. Although the 3 states covered have an aggregate population of 4.3 million women, only 231 represent them in broadcasting. Moreover, female journalists are concentrated in the lowest status positions and tend to be relegated to coverage of women's and social issues rather than news and current affairs. Respondents cited the following factors as responsible for the low representation of women in broadcasting: cultural factors (20 respondents), a late start (15), male chauvinism (5), and a lack of dedication (5). At the same time, 40 of the 45 respondents indicated they believed women have equal opportunities to men in the broadcast media, given ability and perseverance, and 35 ranked the prospects for the next generation of female journalists as wide open. Greater visibility of female broadcasters in the higher ranks of the industry and in news-oriented reporting positions is essential to undercut stereotypes of women as wives and mothers only. Urged is a conscious effort on the part of the Nigerian broadcasting industry to attract more women to the field and provide them with the training needed to career advancement.

    Palm oil production has increased in recent decades and is estimated to increase further. The optimal role of palm oil production, however, is controversial because of resource conflicts with alternative land uses. Local conditions and climate change affect resource competition and the desirability of palm oil production. Based on this, crop yield simulations using different climate model output under different climate scenarios could be important tool in addressing the problem of uncertainty quantification among different climate model outputs. Previous studies on this region have focused mostly on single experimental fields, not considering variations in Agro-Ecological Zones, climatic conditions, varieties and management practices and, in most cases not extending to various IPCC climate scenarios and were mostly based on single climate model output. Furthermore, the uncertainty quantification of the climate- impact model has rarely been investigated on this region. To this end we use the biophysical simulation model APSIM (Agricultural Production Systems Simulator) to simulate the regional climate impact on oil palm yield over the Nigerian Niger Delta. We also examine whether the use of crop yield model output ensemble reduces the uncertainty rather than the use of climate model output ensemble. The results could serve as a baseline for policy makers in this region in understanding the interaction between potentials of energy crop production of the region as well as its food security and other negative feedbacks that could be associated with bioenergy from oil palm.

    Russell-Silver Syndrome (RSS) is a rare cause of pre-natal dwarfism, associated with recognizable dysmorphic features and limb asymmetry. The propositus was a term infant of unrelated Nigerian parents, whose 35-year-old mother had peri-conceptual haloperidol for schizophrenia. Anthropometric values suggested severe prenatal stunting in a term infant with asymmetric "head sparing" intrauterine growth retardation (IUGR). A syndromic consideration of Russell-Silver dwarfism was subsequently predicated on the distinctive dysmorphic craniofacial features of a triangular facial profile with a broad forehead and hypoplastic mandible, right upper and lower limb rhizomelia, clinodactyly of the little fingers, micro-penis, and (unilateral) cryptochidism. Routine care of a small-for-gestational-age infant was pursued, but postnatal growth remained slow (despite adequate caloric provision) until a parent-pressured discharge at 4 weeks. His subsequent demise was said to have occurred "suddenly" 2 weeks post-discharge. Despite the limitations posed by the local paucity of modern investigative tools for genetic disorders, the current case report underscores the diagnostic reality of RSS in a non-white African population. While emphasizing the need for a high index of diagnostic suspicion for congenital malformations and syndromic causes of IUGR in the African sub-region, we suspect a possible etiologic association of haloperidol embryopathy with RSS in the current case. The characteristic features, differential diagnoses, etiologic postulates/current cytogenetic and molecular genetic findings of RSS are fully reviewed in the discussion.

    Background: Cleft lip (CL) and palate (CLP) management is multidisciplinary. A cleft team was formed in a Nigerian Tertiary Hospital to address the health needs of cleft patients in the centre. Aim: This paper aims at documenting the Aminu Kano Teaching Hospital (AKTH) management protocol for orofacial clefts and also to review our experience with CLP surgeries performed at AKTH since our partnering with Smile Train. Materials and Methods: A retrospective review of all the cleft patients surgically treated from January 2006 to December 2014 under Smile Train sponsorship was undertaken. A descriptive narrative of the cleft team protocol was also given. Results: One hundred and fifty-five patients (80 males, 75 females) had surgical repairs of either the lip or palate. CL patients were 83 (53.55%), while CLP patients were 45 (29.03%) and isolated cleft palate patients were 27 (17.42%). Conclusion: The inclusion of various specialities in the cleft team is highly desirable. Poverty level amongst our patients frequently limits our management to surgical treatment sponsored by the Smile Train, despite the presence of other residual problems. PMID:26712291
