The maternal mortality ratio (MMR) of Nigeria remains high. This retrospective study aims to suggest evidence-based strategies towards achieving the sustainable development goal target 3.1 at the Obafemi Awolowo University Teaching Hospital (OAUTHC), Nigeria by providing contemporary data on MMR between October 2012 and September 2015. There were 86 maternal deaths and 5243 live births over the triennium, with annual MMRs of 1744, 1622 and 1512/100,000 live births, respectively. Fifty-six (65.2%) were postpartum deaths, while 44 (51...

Uterine diseases are common in dogs, particularly in countries where elective spaying is not usually performed. The associated clinical illnesses may be of varying degree ranging from merely decreased fertility to a critical pyometra requiring intensive care to survive. The diagnosis of some uterine diseases is generally uncomplicated, such as in a classic pyometra presenting with enlarged, fluid-filled uterus, purulent vaginal discharge and characteristic signs of illness or in other disorders associated with uterine enlargement...

Meharban Singh
Intolerance and grouse against doctors is a global phenomenon but India seems to lead the world in violence against doctors. According to World Health Organization, about 8-38% healthcare workers suffer physical violence at some point in their careers. Many more are verbally abused or threatened. Public is almost behaving like health sector terrorists. The spate of increasing attacks on doctors by damaging their property and causing physical injury is not acceptable by any civilized society. The public is becoming increasingly intolerant to a large number of social issues because of poor governance and vote bank politics...

Stunting remains a major public health concern worldwide. Although its global prevalence is slowly decreasing, the actual number of affected children is still rising in Sub-Saharan Africa. In the Central African Republic (CAR), about one third of all children below the age of five are stunted. Stunting is correlated with many long-term consequences, including poor cognitive development and a higher rate of morbidity and mortality, making stunting a major contributor to poverty. In CAR, little is known about the factors that contribute to stunting...

Hyperphosphatasia with mental retardation syndrome is a heterogeneous genetic condition. Two siblings aged 5 years and 3 years were evaluated for global development delay and facial dysmorphism. A novel missense variant, c.851A>G (p.H284R, NM_033419.3), in PGAP3 was identified using whole-exome sequencing. Assays for elevated alkaline phosphatase and exome sequencing can be useful for the diagnosis of hyperphosphatasia with mental retardation syndrome.

A better understanding of ultrasound transmission through the human skull is fundamental to develop optimal imaging and therapeutic applications. In this study, we present global attenuation values and functions that correlate apparent density calculated from computed tomography scans to shear speed of sound. For this purpose, we used a model for sound propagation based on the viscoelastic wave equation (VWE) assuming isotropic conditions. The model was validated using a series of measurements with plates of different plastic materials and angles of incidence of 0°, 15° and 50°...

BACKGROUND: Patients with arterial perinatal stroke often suffer long-term motor sequelae, difficulties in language, social development, and behaviour as well as epilepsy. Despite homogeneous lesions, long-term behavioural and cognitive outcomes are variable and unpredictable. Sleep-related epileptic encephalopathies can occur after early brain injury and are associated with global developmental delays. We hypothesized that sleep-potentiated epileptiform abnormalities are associated with worse developmental outcomes after perinatal stroke...

S Dharani, R Rakkiyappan, Jinde Cao, Ahmed Alsaedi
This paper explores the problem of synchronization of a class of generalized reaction-diffusion neural networks with mixed time-varying delays. The mixed time-varying delays under consideration comprise of both discrete and distributed delays. Due to the development and merits of digital controllers, sampled-data control is a natural choice to establish synchronization in continuous-time systems. Using a newly introduced integral inequality, less conservative synchronization criteria that assure the global asymptotic synchronization of the considered generalized reaction-diffusion neural network and mixed delays are established in terms of linear matrix inequalities (LMIs)...

Alzheimer's disease (AD) has become a global health issue as the population ages. There is no effective treatment to protect against its occurrence or progression. Some argue that the lack of treatment response is due to delays in diagnosis. By the time a diagnosis of AD is made, neurodegenerative changes are at the stage where very few neurons can be salvaged by medication. The AD research community has developed the idea of mild cognitive impairment (MCI) in an attempt to find predementia patients who might benefit from potentially therapeutic drugs that have proven ineffective in the past...

Hyoung Oh Kim, Sung Jin Yoo
This paper presents a delay-independent nonlinear disturbance observer (NDO) design methodology for adaptive tracking of uncertain pure-feedback nonlinear systems in the presence of unknown time delays and unmatched external disturbances. Compared with all existing NDO-based control results for uncertain lower-triangular nonlinear systems where unknown time delays have been not considered, the main contribution of this paper is to develop a delay-independent design strategy to construct an NDO-based adaptive tracking scheme in the presence of unknown time-delayed nonlinearities and non-affine nonlinearities unmatched in the control input...

BACKGROUND AND AIMS: As the recent outbreak of microcephaly cases caused by Zika virus has been declared a global health emergency, providing assessment guidelines for multidisciplinary teams providing early developmental screening and stimulation to infants with microcephaly is much needed. Thus, the aim of this manuscript is to provide an overview on what is known about neuroradiological aspects and clinical findings in infants with microcephaly caused by Zika virus and to propose a framework for early evaluation of child development...

Xiao Peng, Huaiqin Wu, Ka Song, Jiaxin Shi
This paper is concerned with the global Mittag-Leffler synchronization and the synchronization in finite time for fractional-order neural networks (FNNs) with discontinuous activations and time delays. Firstly, the properties with respect to Mittag-Leffler convergence and convergence in finite time, which play a critical role in the investigation of the global synchronization of FNNs, are developed, respectively. Secondly, the novel state-feedback controller, which includes time delays and discontinuous factors, is designed to realize the synchronization goal...

Dominant mutations in CACNA1A, encoding the α-1A subunit of the neuronal P/Q type voltage-dependent Ca2+ channel, can cause diverse neurological phenotypes. Rare cases of markedly severe early onset developmental delay and congenital ataxia can be due to de novo CACNA1A missense alleles, with variants affecting the S4 transmembrane segments of the channel, some of which are reported to be loss-of-function. Exome sequencing in five individuals with severe early onset ataxia identified one novel variant (p.R1673P), in a girl with global developmental delay and progressive cerebellar atrophy, and a recurrent, de novo p...

The closely related paralogues FOXP2 and FOXP1 encode transcription factors with shared functions in the development of many tissues, including the brain. However, while mutations in FOXP2 lead to a speech/language disorder characterized by childhood apraxia of speech (CAS), the clinical profile of FOXP1 variants includes a broader neurodevelopmental phenotype with global developmental delay, intellectual disability, and speech/language impairment. Using clinical whole-exome sequencing, we report an identical de novo missense FOXP1 variant identified in three unrelated patients...

Bacterial pathogens are one of the primary causes of human morbidity worldwide. Historically, antibiotics have been highly effective against most bacterial pathogens; however, the increasing resistance of bacteria to a broad spectrum of commonly used antibiotics has become a global health-care problem. Early and rapid determination of bacterial susceptibility to antibiotics has become essential in many clinical settings and, sometimes, can save lives. Currently classical procedures require at least 48 h for determining bacterial susceptibility, which can constitute a life-threatening delay for effective treatment...

The possibility of observing satellites with the very long baseline interferometry (VLBI) technique has been discussed for several years in the geodetic community, with observations of either existing satellites of the global navigation satellite systems or of satellites dedicated to realise a space tie. Such observations were carried out using the Australian telescopes in Hobart and Ceduna which, for the first time, integrated all the necessary steps: planning the observations (automated scheduling), correlation of the data and the generation of a series of time delay observables suitable for a subsequent geodetic analysis...

Marieke Haalboom
One of the major global health issues is the existence of chronic wounds. Chronic wounds are wounds that show a delayed, or even failed, healing process. The healing process often stagnates in the inflammatory phase or proliferative phase. Since traditional treatment methods have shown to be of limited effectiveness in chronic wound care, the focus has shifted to increase the knowledge of the wound healing process and the deficiencies encountered in chronic wounds. This increased knowledge has provided the opportunity for development of new diagnostics and therapeutics in chronic wound care that detect and treat specific deficiencies instead of one common treatment for all chronic wounds...

BACKGROUND: The 2016 World Health Organization (WHO) consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection, recommended to start all HIV-infected children on antiretroviral therapy (ART). Here, we explore the possible benefits and risks of implementing universal ART for all HIV-infected children and adolescents and outline some of the key considerations that led to the 2016 revision of WHO guidelines. METHODS: We conducted a review of the published data from 2000 to 2016, to ascertain the clinical and programmatic benefits, as well as the risks of implementing universal ART for all children...

In this research article, a new mathematical model of delayed differential equations is developed which discusses the interaction among CD4 T cells, human immunodeficiency virus (HIV), and recombinant virus with cure rate. The model has two distributed intracellular delays. These delays denote the time needed for the infection of a cell. The dynamics of the model are completely described by the basic reproduction numbers represented by R0, R1, and R2. It is shown that if R0 < 1, then the infection-free equilibrium is locally as well as globally stable...
