    Short tandem repeat (STR) typing continues to be the primary workhorse in forensic DNA profiling. Therefore, the present review discusses the prominent role of STR marker in criminal justice system. All over the world, deoxyribonucleic acid (DNA) profiling provides evidence that may be used to convict criminals, as an irrefutable proof of wrongful convictions, invaluable links to the actual perpetrators of crimes, and could also deter some offenders from committing more serious offences. Clearly, DNA profiling tools have also aided forensic scientists to re-evaluate old cases that were considered closed as a result of inadequate evidence. In carrying out this review, a comprehensive electronic literature search using PubMed, ScienceDirect, Google Scholar and Google Search were used, and all works meeting the subject matter were considered, including reviews, retrospective studies, observational studies and original articles. Case reports presented here, further demonstrates the crucial role of forensic DNA profiling in mitigating and providing compelling evidence for the resolution of crimes. For case report 1, there was a 100% match between the DNA recovered from the items found in the crime scene, and the suspect's DNA sample collected via buccal swab following 15 STR loci examination. Case report 2 further highlights the indispensable contribution of DNA database in solving crime. Therefore, it has become very necessary for developing countries like Nigeria to develop a national DNA database and make policies and legislatures that will further expand and enable the practice of forensic genetics, particularly DNA profiling.

    Multidrug-resistant (MDR) or extensively drug-resistant (XDR) Tuberculosis (TB) is a major challenge to global TB control. Therefore, accurate tracing of in-country MDR-TB transmission are crucial for the development of optimal TB management strategies. This study aimed to investigate the diversity of MTBC in Nigeria. The lineage and drug-resistance patterns of the clinical MTBC isolates of TB patients in Southwestern region of Nigeria were determined using the WGS approach. The phenotypic DST of the isolates was determined for nine anti-TB drugs. The sequencing achieved average genome coverage of 65.99X. The most represented lineages were L4 (n = 52, 83%), L1 (n = 8, 12%), L2 (n = 2, 3%) and L5 (n = 1, 2%), suggesting a diversified MTB population. In term of detection of M/XDR-TB, while mutations in katG and rpoB genes are the strong predictors for the presence of M/XDR-TB, the current study also found the lack of good genetic markers for drug resistance amongst the MTBC in Nigeria which may pose greater problems on local tuberculosis management efforts. This high-resolution molecular epidemiological data provides valuable insights into the mechanistic for M/XDR TB in Lagos, Nigeria.

    Students of the health sciences are the future frontliners to fight pandemics. The students' participation in COVID-19 response varies across countries and are mostly for educational purposes. Understanding the determinants of COVID-19 vaccine acceptability is necessary for a successful vaccination program. This study aimed to investigate the factors associated with COVID-19 vaccine acceptance among health sciences students in Northwest Nigeria. The study was an online self-administered cross-sectional study involving a survey among students of health sciences in some selected universities in Northwest Nigeria. The survey collected pertinent data from the students, including socio-demographic characteristics, risk perception for COVID-19, and willingness to accept the COVID-19 vaccine. Multiple logistic regression was used to determine the predictors of COVID-19 vaccine acceptance. A total of 440 responses with a median (interquartile range) age of 23 (4.0) years were included in the study. The prevalence of COVID-19 vaccine acceptance was 40.0%. Factors that independently predict acceptance of the vaccine were age of 25 years and above (adjusted odds ratio, aOR, 2.72; 95% confidence interval, CI, 1.44-5.16; p = 0.002), instructions from heads of institutions (aOR, 11.71; 95% CI, 5.91-23.20; p<0.001), trust in the government (aOR, 20.52; 95% CI, 8.18-51.51; p<0.001) and willingness to pay for the vaccine (aOR, 7.92; 95% CI, 2.63-23.85; p<0.001). The prevalence of COVID-19 vaccine acceptance among students of health sciences was low. Older age, mandate by heads of the institution, trust in the government and readiness to pay for the vaccine were associated with acceptance of the vaccine. Therefore, stakeholders should prioritize strategies that would maximize the vaccination uptake.

    J Environ Sci Health A Tox Hazard Subst Environ Eng, 2012;47(10):1455-65.
    PMID: 22571534 DOI: 10.1080/10934529.2012.673305
    Multivariate statistical techniques such as hierarchical Agglomerated cluster analysis (HACA), discriminant analysis (DA), principal component analysis (PCA), and factor analysis (FA) were applied to identify the spatial variation and pollution sources of Jakara River, Kano, Nigeria. Thirty surface water samples were collected: 23 along Getsi River and 7 along the main channel of River Jakara. Twenty-three water quality parameters, namely pH, temperature, turbidity, electrical conductivity (EC), dissolved oxygen (DO), 5-day biochemical oxygen demand (BOD(5)), Faecal coliform, total solids (TS), nitrates (NO(3)(-)), phosphates (PO(4)(3-)), cobalt (Co), iron (Fe), nickel (Ni), manganese (Mn), copper (Cu), sodium (Na), potassium (K), mercury (Hg), chromium (Cr), cadmium (Cd), lead (Pb), magnesium (Mg), and calcium(Ca) were analysed. HACA grouped the sampling points into three clusters based on the similarities of river water quality characteristics: industrial, domestic, and agricultural water pollution sources. Forward and backward DA effectively discriminated 5 and 15 water quality variables, respectively, each assigned with 100% correctness from the original 23 variables. PCA and FA were used to investigate the origin of each water quality parameter due to various land use activities, 7 principal components were obtained with 77.5% total variance, and in addition PCA identified 3 latent pollution sources to support HACA. From this study, one can conclude that the application of multivariate techniques derives meaningful information from water quality data.

    J Environ Sci Health A Tox Hazard Subst Environ Eng, 2012;47(11):1551-60.
    PMID: 22702815 DOI: 10.1080/10934529.2012.680415
    The pollution status of the downstream section of the Jakara River was investigated. Dissolved oxygen (DO), 5-day biochemical oxygen demand (BOD(5)), chemical oxygen demand (COD), suspended solids (SS), pH, conductivity, salinity, temperature, nitrogen in the form of ammonia (NH(3)), turbidity, dissolved solids (DS), total solids (TS), nitrates (NO(3)), chloride (Cl) and phosphates (PO(3-)(4)) were evaluated, using both dry and wet season samples, as a measure of variation in surface water quality in the area. The results obtained from the analyses were correlated using Pearson's correlation matrix, principal component analysis (PCA) and paired sample t-tests. Positive correlations were observed for BOD(5), NH(3), COD, and SS, turbidity, conductivity, salinity, DS, TS for dry and wet seasons, respectively. PCA was used to investigate the origin of each water quality parameter, and yielded 5 varimax factors for each of dry and wet seasons, with 70.7 % and 83.1 % total variance, respectively. A paired sample t-test confirmed that the surface water quality varies significantly between dry and wet season samples (P < 0.01). The source of pollution in the area was concluded to be of anthropogenic origin in the dry season and natural origins in the wet season.

    Musa ZA, Soh KL, Mukhtar F, Soh KY, Oladele TO, Soh KG
    Psychiatry Res, 2021 02;296:113680.
    PMID: 33421840 DOI: 10.1016/j.psychres.2020.113680
    The objective of this paper was to examine the efficacy of mindfulness-based cognitive therapy (MBCT) in decreasing depressive symptoms and intellectual disabilities (ID) among individuals with depression in Nigeria. In this randomized controlled trial, 101 participants with depression and ID, aged 18-60 years, who obtained 14 scores in the Beck Depression Inventory (BDI-II), scores 4 and above on Shaheen Disability Scale (SDS), were randomly assigned into the interventions (n = 50) and active control group (n = 51). The MBCT group has shown a statistically significant effect on the SDS and BDI-II variables by decreasing depressive symptoms and disabilities following MBCT (p<0.05). The assessment revealed that participants reported an improvement in their experience of depression and ID. The most significant impact was in the reduced levels of ID reported. The results of the evaluation suggest that depressed people with intellectual disabilities benefit from a structured MBCT group intervention and the results are maintained at 2-months follow-up.

    Muhammed A, Shariff-Ghazali S, Said SM, Hassan M, Lee K
    J Community Health Nurs, 2020 4 3;37(2):77-88.
    PMID: 32233947 DOI: 10.1080/07370016.2020.1736377
    We developed and psychometrically tested a Theory of Planned Behavior (TPB) questionnaire which focused on assessing the midwives' intention to provide planned home birth (PHB) services. This is a quantitative, cross-sectional survey, conducted among 226 midwives working in ten participating health facilities. The reliability and validity of the theoretical constructs were assessed. The Cronbach's alpha values were >0.8 for all scales, suggesting satisfactory internal consistency. Confirmatory factor analysis revealed sufficient convergent validity (the average variance extracted was >0.5 for each construct) and discriminant validity. The study gathered an evidence of the usefulness of TPB in the specific context of PHB.

  8. Predictors of midwives' intention to provide planned home birth services to low-risk women: A theory of planned behaviour approach
    Muhammed A, Khuan L, Shariff-Ghazali S, Said SM, Hassan M
    Midwifery, 2019 Jun;73:62-68.
    PMID: 30884373 DOI: 10.1016/j.midw.2019.03.004
    OBJECTIVE: Planned home birth may increase women's access to skilled midwives in all settings. Using theory to understand and predict midwives' intention regarding planned home birth services is rare. Therefore, using the theory of planned behaviour, we determined the factors associated with midwives' intention to provide planned home birth services to low-risk women.

    DESIGN: This cross-sectional study adopted a quantitative approach and a survey. Stratified random sampling was used to recruit 226 midwives in Sokoto, Nigeria. Data-including descriptive statistic and multiple linear regression analyses-were analysed using SPSS 23 and significant was set at 0.05.

    SETTING: Ten public health facilities in Sokoto, northwestern Nigeria.

    PARTICIPANTS: Among all 460 midwives (women aged 20-60 years), working in the maternity wards of health facilities in Sokoto, a sample of 226 midwives was calculated using a power of 0.80 and a 95% confidence interval.

    FINDINGS: The multiple linear regression analyses confirmed that the major factors associated with midwives' intention to provide planned home birth services were midwives' attitude towards planned home birth (p < .001) and midwives' previous experience with planned home birth practice (p = .008).

    CONCLUSIONS AND IMPLICATIONS: The theory of planned behaviour is a useful framework for identifying factors that affect midwives' intention to provide planned home birth services. While future research may employ a qualitative approach to explore other factors, planned home birth education campaigns should target information that enhances positive attitude and encourages midwives to provide planned home birth services.

    Birth, 2023 Sep;50(3):587-595.
    PMID: 36226886 DOI: 10.1111/birt.12681
    BACKGROUND: The majority of women in Sokoto, Nigeria prefer homebirths, but midwives are reluctant to provide care in the home setting. As such, many women continue to give birth at home alone or assisted by untrained attendants, which is associated with an increased risk for maternal and neonatal morbidity and mortality.

    METHODS: A randomized controlled trial was conducted among 226 midwives from 10 health care facilities. The intervention group received an educational program on home birth. A validated questionnaire that evaluated knowledge, attitudes, norms, perceived control, and intention to provide planned home birth care was given at baseline, immediately after the intervention, and at three-months follow-up. Data were analyzed using linear mixed-effect model statistics.

    RESULTS: Following the intervention, the intervention group demonstrated higher knowledge and more positive attitudes, norms, perceived control, and intention to provide planned home birth care compared with the control group (P  0.05).

    DISCUSSION: Educating midwives on planned home birth increases their willingness to provide planned home birth care. Health system administrators, policymakers, and researchers may use similar interventions to promote skilled home birth attendance by midwives. Increasing the number of midwives who are willing to attend planned home births provides women at low risk for medical complications with safer options for labor, delivery, and postpartum care.

  10. Relationships between Media Exposure and Knowledge, Attitude, and Practice on HIV/AIDS: A Cross Sectional Survey of Adolescent Islamiyya Girls in Nigeria
    Muhammad Hamid A, Tamam E, Nizam Bin Osman M
    Health Commun, 2020 04;35(4):419-429.
    PMID: 30700145 DOI: 10.1080/10410236.2018.1564960
    Exposure to HIV/AIDS media among adolescents in sub-Saharan Africa was reported as low in the early 2000s, but now given developments in technology and program appeal, there emerges a need for reassessment. Given that communication, particularly through the media plays a major role in stemming the spread of the epidemic, this study examines the HIV/AIDS media exposure, knowledge, attitude, and practice (KAP) of adolescent Islamiyya girls in northern Nigeria as a predominantly Muslim society. The objectives of the study were to (1) identify the girls' major sources of information on HIV/AIDS; (2) assess their exposure to HIV/AIDS media and their HIV/AIDS knowledge, attitude and practice; and (3) verify relationships between media exposure and HIV/AIDS KAP. Based on the Advertising Research Foundation's Hierarchy of Effects model, hypotheses were posed to test the relationships. A questionnaire survey was administered on a randomly selected sample of 500 Islamiyya girls in Bauchi, Nigeria, from an estimated population of 35,000. Results were analyzed using descriptive statistics and partial least squares structural equation modeling. The results showed media exposure is not a significant predictor of HIV/AIDS practice, but it is a significant predictor of HIV/AIDS knowledge. And HIV/AIDS knowledge significantly predicted both HIV/AIDS attitude and practice. HIV/AIDS attitude also significantly predicted HIV/AIDS practice. It is thus concluded that among Nigerian adolescent girls, exposure to HIV/AIDS media is a necessary but not a sufficient predictor of HIV/AIDS KAP.

    Radiat Prot Dosimetry, 2010 Sep;141(2):127-33.
    PMID: 20562117 DOI: 10.1093/rpd/ncq162
    Stratified sampling procedure was employed to collect a total of 40 samples; 2 from each stratum, measuring an approximate dimension of 3.25 km(2) of the actual sample site. Appropriate volumes were then evaporated and transferred into clean stainless steel planchets (ISO 9696 and ISO 9697). An eight channel gas-flow proportional counting system connected to a microprocessor loaded with a spreadsheet programme (Quarttro-Pro) and graphic programme (Multiplan) initially calibrated for efficiency was employed to count the background and the prepared samples. A mean efficiency of 33.44 and 41.24 % for the respective alpha and beta sources was obtained. A low background activity was also observed with a mean of 0.165 Bq for alpha and 1.119 Bq for beta. The gross alpha and beta activity concentrations in the water were found to range from 80 +/- 0.05 to 2300 +/- 0.41 Bq m(-3) and 120 +/- 0.08 to 4970 +/- 0.78 Bq m(-3), respectively. This clearly indicate areas of elevated alpha and beta activity concentrations of 37.5 and 47.5 %, respectively when compared with the International Commission for Radiological Protection (1991) maximum acceptable values of 500 Bq m(-3) for alpha and 1000 Bq m(-3) for beta.

    Biomed Res Int, 2014;2014:302097.
    PMID: 25276774 DOI: 10.1155/2014/302097
    This study aims to test the translated Hausa version of the stroke impact scale SIS (3.0) and further evaluate its psychometric properties. The SIS 3.0 was translated from English into Hausa and was tested for its reliability and validity on a stratified random sample adult stroke survivors attending rehabilitation services at stroke referral hospitals in Kano, Nigeria. Psychometric analysis of the Hausa-SIS 3.0 involved face, content, criterion, and construct validity tests as well as internal and test-retest reliability. In reliability analyses, the Cronbach's alpha values for the items in Strength, Hand function, Mobility, ADL/IADL, Memory and thinking, Communication, Emotion, and Social participation domains were 0.80, 0.92, 0.90, 0.78, 0.84, 0.89, 0.58, and 0.74, respectively. There are 8 domains in stroke impact scale 3.0 in confirmatory factory analysis; some of the items in the Hausa-SIS questionnaire have to be dropped due to lack of discriminate validity. In the final analysis, a parsimonious model was obtained with two items per construct for the 8 constructs (Chi-square/df < 3, TLI and CFI > 0.9, and RMSEA < 0.08). Cross validation with 1000 bootstrap samples gave a satisfactory result (P = 0.011). In conclusion, the shorter 16-item Hausa-SIS seems to measure adequately the QOL outcomes in the 8 domains.

    The purpose of this project is to evaluate the suitability of different sites as locations for obtaining underground water for consumption. The analysis of ²³⁸U, ²³²Th and ⁴⁰K from rock samples from each layer of borehole at a depth of ∼50 m at Site A borehole, S3L1-S3L6 in Gosa and 40 m at Site B borehole, S4L1-S4L5 in Lugbe, Abuja, north central Nigeria is presented. The gamma-ray spectrometry was carried out using a high-purity germanium detector coupled to a computer-based high-resolution multichannel analyzer. The activity concentrations at Site A borehole for ²³⁸U have a mean value of 26 ± 3, ranging from 23 ± 2 to 30 ± 3 Bq kg⁻¹, ²³²Th a mean value of 63 ± 5, ranging from 48 ± 4 to 76 ± 6 Bq kg⁻¹ and ⁴⁰K a mean value of 573 ± 72, ranging from 437 ± 56 to 821 ± 60 Bq kg⁻¹. The activity concentrations at Site B borehole for ²³⁸U have a mean value of 20 ± 2, ranging from 16 ± 2 to 23 ± 2 Bq kg⁻¹, ²³²Th a mean value of 46 ± 4, ranging from 43 ± 4 to 49 ± 4 Bq kg⁻¹, ⁴⁰K a mean value of 915 ± 116 and ranging from 817 ± 103 Bq kg⁻¹ to 1011 ± 128 Bq kg⁻¹. It is noted that the higher activity concentrations of ²³²Th and ²³⁸U are found in Site A at Gosa. Site B has lower radioactivity, and it is recommended that both sites are suitable for underground water consumption.

    Though cases of AIDS are visible in Nigeria and awareness of HIV is high, correct knowledge on HIV transmission and prevention has remained low with significant numbers of people living with HIV/AIDS having low attitudes towards life and the disease itself. This study determined the baseline knowledge on HIV transmission and prevention, and attitudes towards HIV/AIDS of adult HIV positive patient enrolled into care at all four comprehensive antiretroviral therapy (ART) sites in Yola, Nigeria. Baseline reports on the knowledge and attitudes of adult HIV positive patients were obtained from a three arm randomized single blind clinical trial involving 386 randomly selected adult HIV patients who were enrolled into ART care at all four comprehensive ART sites in Yola. An administered, validated structured questionnaire was used for data collection. Outcome measures were sound knowledge on HIV transmission and prevention, and attitudes towards HIV/AIDS. Data was analyzed using SPSS version 22. Test of significance was at α level 0.05. Overall 237 (61.4%) had sound knowledge on HIV transmission and prevention, while 346 (89.6%) of respondents had high attitudes towards HIV/AIDS. Though majority of respondents had sound knowledge on HIV transmission and prevention as well as high attitudes towards HIV/AIDS, interventions to improve knowledge and attitudes among this group of individuals would improve positive preventive strategies.

    The Climatic performance of courtyard residential buildings needs to be
    investigated if the assertion that courtyard is a microclimate modifier is to be
    accepted. Therefore, this study seeks to examine the microclimatic performance
    of two existing courtyard residential buildings with similar characteristics in
    Kafanchan-Kaduna Nigeria, -the fully enclosed courtyard residential building and
    the semi-enclosed courtyard residential building. The purpose of this research is
    to investigate their microclimatic performances in other to establish the best
    courtyard house. This study uses measurement to achieve its aim. The tool
    employed for data collection is the Hobo Weather Data Loggers (HWDL). Three
    HWDL were used to collect data in the two case-study, and the third one was
    placed in the outside area as a benchmark. Only air temperature and relative
    humidity were measured. This study revealed a tangible difference in the
    microclimatic performance of the two case-study. The fully enclosed courtyard
    residential building is seen to have air temperature difference of 1 oC to 3 oC, and
    the relative humidity difference of 4 % to 8 %. In conclusion, the fully enclosed
    courtyard house demonstrated a more favorable microclimatic performance than
    the semi-enclosed, and further simulation studies towards its optimization are
    required.

    Five improved Nigerian barley cultivars (ESCOBA, ASE – 2, ALOE, GOB – 2, SUMBARD) were obtained from Lake Chad Research Institute Maiduguri, Nigeria, and their physicochemical, malting and biochemical properties investigated employing standard procedures. Data were analyzed by means of ANOVA [at 95% significant level] and correlations using SPSS 14 software. Results showed GOB-2 grain and malt recording the highest kernel weight (47.50 g) and kernel volume (41.21 ml); whereas ALOE grain had the longest kernel length (13.40 mm) and GOB-2 the shortest (9.40 mm). GOB-2 had the largest major diameter (3.39 mm) and SUMBARD had the least (2.86 mm). ESCOBA, SUMBARD and ASE-2 cultivars had the highest protein values (as %N) of 14.90%, 13.90% and 13.69% respectively, while ALOE, ASE-2 and GOB-2 had the highest total carbohydrates of 69.97, 69.39 and 68.90% respectively. All the cultivars had good germinative capacities (> 90%), with GOB-2 and ASE-2 having the highest germinative energy values of 96.65% and 95.00%. No significant (p > 0.05) changes
    in the dimension of the kernels after malting. SUMBARD recorded the highest malt yields (88.55%) followed by ASE-2 (83.45%) and ALOE (82.00%). The highest α-amylase activities of 105.34 and 96.23 unit/mg protein/min were recorded by ASE-2 and ALOE, respectively, with corresponding diastatic powers of 81.92 and 76.23oL. Thousand kernel weight correlated positively with protein (r = 0.500, P < 0.05) and with total soluble solids (r = 0.435, p < 0.05) but negatively with α-amylase (r = -0.869, p < 0.05) and with diastatic power (r = -0.838, p < 0.05). This study showed that the cultivars have good potentials for use as malting materials in beverage making.

    Reproductive and Maternal health are an important components of public health and medicine which are concerned with the complete state of physical, mental and social wellbeing in all matters regarding reproductive system and health of mother especially during pregnancy.It implies ensuring that all women receive the care they need to be safe and healthy throughout pregnancy, childbirth and beyond. However, according to World Health Organization, millions of women all over the world do not have access to good quality health services during pregnancy and childbirth resulting in mortalities. Islam is a complete way of life. The Qur’an and Hadith consider pregnancy and child bearing as signs among other signs of the divine existence of Allah.The importance of maternal and reproductive is thus not unexplained in the Islamic perspectives. The study look at what role Muslim religious leaders can play in the prevention of maternal deaths and morbidities in developing countries. A qualitative study was conducted through in-depth interviews and focus groups discussion with a purposive sample of some Muslim religious leaders from Gusau local government area of Zamfara state northwest Nigeria in order to elicit information about the Islamic perspectives of reproductive and maternal health and the roles they can play in the prevention of maternal deaths among the Muslim communities. Muslim Religious leaders have a crucial role and contribution for the attainment and maintenance of good heath of women and children among Muslim communities through public enlightenment in the context of ‘ilm’, providing guidance through ‘Fatwah’ and community mobilization in the spirit brotherhood ‘ukhuwah’.Islam does not accept the “preventable death of a woman” due to childbirth or pregnancy. Thus, Islam encourages attendance of antenatal care visits and health care seeking.

    In the current situation of global aging, the current market shortage of age-appropriate smart home products and the recent epidemic have led to greater isolation of the elderly, seriously affecting their physical and mental health. In order to optimize the sustainable user experience of the elderly when using smart home products, this paper proposes a research method based on Quality Function Deployment (QFD) for the optimal design of user experience of smart home products for the elderly, taking the design of age-appropriate home smart refrigerators as an example. Firstly, based on the results of market research and user interviews, the requirements of smart refrigerators for the elderly are screened and integrated, and the Kano model is used to prioritize these needs, resulting in the identification of important features needed in smart refrigerators for the elderly. Secondly, based on QFD, user requirements are transformed into design requirements, and a quality house model is established to ascertain the degree of importance of each design requirement through user ratings so as to obtain the key requirements as the theoretical basis for the solution design. Finally, optional solutions are generated for concept evaluation based on PUGH concept selection, comparing the advantages and disadvantages of the solutions and recombining them into an evaluation to determine the best solution. The quantitative evaluation of the four solutions reveals that Solution A has the highest score of 117.358, followed by Solution D with 113.259, Solution B with 96.415, and Solution C with 85.511, which is the lowest. The scoring allows the best design solution to be selected and applied to product development. The results show that the introduction of the Kano model and PUGH concept selection into QFD can be effectively used as a research method for optimizing the user experience of smart refrigerators for the elderly, and a corresponding design strategy for sustainable user experience optimization is proposed. The method and strategy provide guidance for the innovative design of new smart home products.
