Patientâdoctor relationship: The practice orientation of doctors in Kano
Background and Objectives: Attitude and orientation of doctors to the doctorâpatient relationship has a direct influence on delivery of high quality healthâ care. No study to the knowledge of these researchers has so far examined the practice orientation of doctors in Nigeria to this phenomenon. The aims of this study were to determine the orientation of Kano doctors to the practice of doctorâpatient relationship and physiciansâ relatedâfactors.Materials and Methods: Participants were doctors working in four major hospitals (i.e., two federalâowned and two stateâowned) servicing Kano State and its environs. The PatientâPractitioner Orientation Scale (PPOS) and a socioâdemographic questionnaire were completed by the 214 participants. The PPOS has 18 items and measures three parameters of a total score and two dimension of âsharingâ and âcaringâ.Results: The mean age of participants was 31.72 years (standard deviation = 0.87), with 22% being females, 40.7% have been practicing for â„6 years and about twoâthird working in federalâowned health institution. The Cronbachâs alpha of total PPOS scores was 0.733 and that of two subâscale scores of âsharingâ and âcaringâ were 0.659 and 0.546 respectively. Most of the doctorsâ orientation (92.5%) was towards doctorâcentered (i.e., paternalistic) care, majority (75.2%) upheld the view of not sharing much information and control with patients, and showing little interest in psychosocial concerns of patients (i.e., âcaringâ=93.0%). Respondentsâ characteristics that were significantly associated with high doctor âcaringâ relationship orientation were being â„30âyearâold and practicing for â„6 years. Working in Stateâowned hospitals was also significantly associated with high doctor âsharingâ orientation.Conclusion: This paper demonstrated why patientâcentered medical interviewing should be given top priority in medical training in Nigeria, and particularly for federal health institutions saddled with production of new doctors and further training for practicing doctors.Key words: Doctorâpatient relationship, Kano doctors, practice orientation, patientâcentered car
Perceptions of People Towards Youth with Autism Spectrum Disorder and Intellectual Disability in North Eastern Nigeria
This paper examined peopleâs perception towards youth with Autism spectrum disorder (ASD) and intellectual disability. In-depth interviews were conducted separately with a with autism spectrum disorder (ASD), Intellectual disabilities (ID) While their mothers were thoroughly investigated in order to ascertain the level of victimization in the form of bullying on these categories of youth constructs from the interview were utilized to compare groups on the frequency type and impact of victimization. The outcomes of the interview conducted reveals that youth with ASD are being victimized more frequently than their ID peers and that the form of bullying being subdued differs from each group to another. In view of submission our findings show that higher internalizing problem and conflicts in relationship are found to be a significant predictor of victimization. The paper, therefore, recommends among others that observation of extrinsic and intrinsic behaviors for proper adjustment in a classroom setting should be taken care off
Volatile fatty acids production in ruminants and the role of monocarboxylate transporters: A review
Monocarboxylates commonly referred to as short-chain fatty acids (SCFAs) are metabolized to different extents by the epithelium of the gastrointestinal tract. They are absorbed along different segments of the gastrointestinal tract and constitute a significant amount of energy in ruminants. Monocarboxylates play a central role in cellular metabolism and metabolic communication between tissues. Essential to these roles is their rapid transport across the plasma membrane, which is catalyzed by a recently identified family of proton-linked monocarboxylate transporters (MCTs). Monocarboxylate transporter-1 and 4 have been shown to interact specifically with OX-47 (CD147), a member of the immunoglobulin superfamily with a single transmembrane helix. This interaction appears to assist MCT expression at the cell surface. Despite the importance of short-chain fatty acids in being the main energy source in ruminant animals, the mechanism of SCFAs transport and absorption is still not fully studied. The aim of this review is to critically discuss short-chain fatty acids production and the functional role of monocarboxylate transporters in relation to the transport and absorption of these nutrients along the gastrointestinal tract of ruminants. Two major functions of monocarboxylate transporter proteins, namely the facilitation of the absorption of SCFAs in the gastrointestinal tract and the regulation of cell pH in skeletal muscles, are clearly very important for physiological homeostasis, animal welfare and productivity.Key words: Ruminants, monocarboxylates, monocarboxylate transporters, CD147
Unlocking Rural and Remote Coverage with Small Cells and Satellite
According to the Global System for Mobile Alliance (GSMA), in 2017, there were around 3.3 billion people connected to the mobile Internet. This represented an upward surge in global coverage compared to previous years. However, more than one billion people are still not covered by mobile broadband networks, representing what is termed âthe coverage gapâ. Uncovered populations typically live in rural locations with low population densities, low per-capita income levels and weak or non-existent enabling infrastructure, and thus, closing the mobile coverage gap seems to be more of an economic challenge, than a pure technical one. This paper presents an overview of the need for rural and remote coverage, both from an operator and consumer as well as government perspective. It then presents the major challenges, and necessary actions to be taken by industry, Government and other stake-holders to drive rural and remote coverage by significantly lowering the cost of network roll-out and increase incentives for such deployments. The paper therefore, presents a technical and business case for the use of âSmall Cellsâ in conjunction with satellites with a view to opening up huge markets via collaboration between the mobile operators and satellite system owners, while offering significant improvements in the coverage and capacity needs of remote, rural or underserved end-users in a cost-effective and scalable manner. Detailed insights to these two technologies are presented, including the innovations to overcome technical and regulatory challenges. Lastly, some real-life deployments are given and the paper concludes with some recommendations for Government and network operators presente
Deforestation, desert encroachment, climate change and agricultural production in the Sudano-Sahelian Region of Nigeria
This work presents a systematic review of relevant literatures centered on the deforestation, desertification climate change hazards and agriculture related problems caused as a result of these natural and human activities with the hope of understanding the situation for better way out. Findings revealed that desertification affects about one sixth of the worldâs population, 70% of all dry lands, amounting to 3.6 billion ha, and one quarter of the total land area of the world. The worsening problem of desertification is quite glaring that an estimate of between 50 % and 75 % of Adamawa, Bauchi, Borno, Gombe, Jigawa, Kano, Katsina, Kebbi, Sokoto, Yobe, and Zamfara states in Nigeria are affected by desertification and are particularly vulnerable to wind erosion due to land clearing for agricultural purposes such as grazing, planting of crops, demand for woods, mining, growth of urbanization and development of infrastructures. Desert encroachment as a degradation of land in arid, semi-arid and sub-humid dry areas caused mainly by climatic changes and human activities; In Nigeria, the dry land parts of the country are more prone to desertification. However, climate change causes uncertainties and variation in the pattern of rainfalls, high temperatures, floods and farmlands destruction, pests and diseases. Leading to irregular and unpredictable rains and increase in sunshine hours, crops and livestock failures as well as food insecurity in general. It was suggested therefore that effective policy and planning measures should be put in place in order to overcome these problems.Keywords: Deforestation, desert encroachment, climate change, agricultur
Outcome of instrumental vaginal delivery in university of Abuja teaching hospital: a five-year review
Background: Most women will achieve spontaneous vaginal delivery; however, a few will need assistance in form of Instrumental vaginal delivery (IVD). These are employed to shorten the second stage on labour and to minimize the incidence of cesarean section. The aim of the study was to determine the prevalence and outcomes of instrumental vaginal delivery at the University of Abuja teaching hospital.Methods: This was a retrospective study of women who had instrumental vaginal delivery over a 5-year period at the University of Abuja teaching hospital. Data on socio-demographic variables, type of instrumental delivery performed, Apgar scores of neonates delivered, indications and complication were obtained from the labour ward registers and case notes of patients and entered into a proforma and analysed using SPSS software for Windows version 23.Results: Instrumental vaginal delivery (IVD) rate performed for both Vacuum or Forceps) was 0.99%, Forceps delivery was 0.30% and vacuum accounted for 0.69% of all deliveries. The mean maternal age was 27.53±5.5 years and 51 (54.8%) of the parturient were primigravidae, 55 (59.1%) were booked patients. Delayed second stage of labour (38.7%) was the most common indications for IVD. Maternal complications noted were genital tract laceration 17 (18.3%) and primary post-partum haemorrhage 10 (10.8%). The mean APGAR scores was 6 and 8 in the first and fifth minutes respectively, live births were 85 (91.4%), stillbirths were 7 (7.5%) and one early neonatal death was recorded (1.1%) due to asphyxia as a result of difficult forceps delivery.Conclusions: The IVD rate at UATH is low with good maternal and fetal outcome and preference for vacuum delivery
Disease Outbreaks: Tuning Predictive Machine Learning
Climate change is expected to exacerbate diarrhoea outbreaks in
developing nations, a leading cause of morbidity and mortality in
such regions. The development of predictive models with the
ability to capture complex relationships between climate factors and
diarrhoea may be effective for diarrhoea outbreak control. Various
supervised Machine Learning (ML) algorithms and Deep Learning
(DL) methods have been used in developing predictive models for
various disease. Despite their advances in a range of healthcare applications, overall method task performance still largely
depends on available training data and parameter settings which is
a significant challenge for most predictive machine learning methods. This study investigates the impact of Relevance Estimation
and Value Calibration (REVAC), an evolutionary parameter optimization method applied to predictive task performance of various
ML and DL methods applied to ranges of real-world and synthetic
data-sets (diarrhoea and climate based) for daily diarrhoea outbreak
prediction in a regional case-study (South African provinces). Preliminary results indicate that REVAC is better suited for the DL
models regardless of the data-set used for making predictions
Predicting Disease Outbreaks with Climate Data
The incidence of most diseases varies greatly with
seasons, and global climate change is expected to increase
its risk. Predictive models that automatically capture trends
between climate and diseases are likely to be beneficial in
minimizing disease outbreaks. Machine learning (ML) predictive
analytic tools have been popularized across many health-care
applications, however the optimal task performance of such
ML tools largely depends on manual parameter tuning and
calibration. Such manual tuning significantly limits the full
potential of ML methods, especially for high-dimensional and
complex task domains, as typified by real-world health-care
application data-sets. Additionally, the inaccessibility of many
health-care data-sets compounds innate problems of method
comparison, predictive accuracy and the overall advancement of
ML based health-care applications. In this study we investigate
the impact of Relevance Estimation and Value Calibration, an
evolutionary parameter optimization method applied to automate
parameter tuning for comparative ML methods (Deep learning
and Support Vector Machines) applied to predict daily diarrhoea
cases across various geographic regions. Data-augmentation is
also used to complement real-world noisy, sparse and incomplete
data-sets with synthetic data-sets for training, validation and
testing. Results support the efficacy of evolutionary parameter
optimization and data synthesis to boost predictive accuracy in
the given task, indicating a significant prediction accuracy boost
for the deep-learning models across all data-sets
Effects of Tyre Derived Aggregate (TDA) as Partial Replacement of Coarse Aggregate in Concrete
The usage and reuse of waste tyre rubber in concrete production can cut down the use of raw materials which contributes to economic efficiency and sustainable development of the construction industry. This study is directed at assessing the effects of using the Tyre Derived Aggregate (TDA) as a substitute for coarse aggregate in concrete. A sum of eighty-six square cubes of 100 mm was cast and cured in fresh water for up to 28 days. Setting times, consistency and soundness tests were carried out on cement paste. However, slump, compressive strength and durability (i.e. water absorption) tests were carried out on the concrete. The results unveiled that the physical characteristics of cement considered fulfilled BS EN 196-3 (1995), and the slump of fresh concrete decreased as the percentage of TDA content stepped up. The water absorption raised, while the density of concrete made with TDA decreased as the percentage of TDA content stepped up. However, the strength of TDA-concrete increased as the curing age increased, and it decreased as the portion of TDA content raised. Nevertheless, the strength at 0%, 5% and 10% were 23, 21.67 and 18.33 N/mm2 respectively. However, the strength of TDA-concrete made with 0 % TDA and 5 % TDA subjected to different temperatures decreased as the temperature increased, however, even at 500C the strength of concrete made with 5% TDA was found to be 20.5 N/mm2 which is within the target compressive strength. It was concluded that the usage of TDA content in the production of concrete should not be greater than 5 % for better performance
