Background: Studies reporting factors associated with exclusive breastfeeding are mostly quantitative. No study has performed a systematic qualitative summary to document the recurring constraints and facilitators to exclusive breastfeeding in sub-Saharan African countries from breastfeeding mothers’ perspective. This study systematically reviews the literature reporting barriers and facilitators to exclusive breastfeeding from the breastfeeding mothers’ perspective in sub-Saharan Africa to develop an educational intervention to optimize exclusive breastfeeding. Methods: A systematic literature review of qualitative studies such as phenomenological studies, followed by a risk of bias and methodological assessment of the included studies’ quality using the Critical Appraisal Skills Programme (CASP) tool was conducted. MEDLINE and Google Scholar were searched from January 1990 to October 2019 to retrieve studies of breastfeeding mothers who had infants aged between 0 and 12 months. Two authors independently carried out the review process and resolved disagreements through consensus. We analyzed the data thematically. Results: After reviewing 92 studies, 20 studies involving 836 participants from 11 countries were eligible. Of the 72 studies excluded, 39 were not conducted in sub-Saharan Africa, and 33 included other participants such as fathers. Three themes emerged as barriers to exclusive breastfeeding (EBF) and five additional themes were identified with facilitators of maternal-infant factors being the most significant in both cases. Maternal employment and knowledge of the benefits of EBF were the most common maternal-infant factors that served as a barrier and a facilitator, respectively. The study’s limitations were that the review involved only primary research among breastfeeding mothers living in sub-Saharan Africa and excluded studies not available in the English language. The information synthesized from this review could be used to develop communication strategies employed during individual and group patient education in the hospitals to improve breastfeeding mothers’ understanding, acceptance, and practice of exclusive breastfeeding. This review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42020133761. Conclusions: This review found that maternal-infant factors have the most significant influence over the practice of exclusive breastfeeding. Therefore, interventions targeted towards maternal-infant factors will improve and optimize exclusive breastfeeding significantly and, ultimately, improve maternal-child health outcomes.

Single photon emission tomography/computed tomography (SPECT/CT) is a mature imaging technology with a dynamic role in the diagnosis and monitoring of a wide array of diseases. This paper reviews the technological advances, clinical impact, and future directions of SPECT and SPECT/CT imaging. The focus of this review is on signal amplifier devices, detector materials, camera head and collimator designs, image reconstruction techniques, and quantitative methods. Bulky photomultiplier tubes (PMTs) are being replaced by position-sensitive PMTs (PSPMTs), avalanche photodiodes (APDs), and silicon PMs to achieve higher detection efficiency and improved energy resolution and spatial resolution. Most recently, new SPECT cameras have been designed for cardiac imaging. The new design involves using specialised collimators in conjunction with conventional sodium iodide detectors (NaI(Tl)) or an L-shaped camera head, which utilises semiconductor detector materials such as CdZnTe (CZT: cadmium–zinc–telluride). The clinical benefits of the new design include shorter scanning times, improved image quality, enhanced patient comfort, reduced claustrophobic effects, and decreased overall size, particularly in specialised clinical centres. These noticeable improvements are also attributed to the implementation of resolution-recovery iterative reconstructions. Immense efforts have been made to establish SPECT and SPECT/CT imaging as quantitative tools by incorporating camera-specific modelling. Moreover, this review includes clinical examples in oncology, neurology, cardiology, musculoskeletal, and infection, demonstrating the impact of these advancements on clinical practice in radiology and molecular imaging departments.

COVID-19 was first reported on 31 December 2019 and has so far claimed over 2,000 lives in Nigeria. Through global and national efforts, about 4 million doses of the AstraZeneca vaccine was distributed and used in Nigeria from March 2021. Vaccine hesitancy could pose a serious problem for COVID-19 prevention and control. To estimate the proportion of the Nnamdi Azikiwe University community that is willing to be vaccinated against COVID-19; level of hesitancy and its associated factors. A cross-sectional survey was conducted using online Google form distributed to staff and students of the university via different WhatsApp groups. The outcome measures were the proportion of persons willing to be vaccinated, vaccine hesitancy rates and reasons for this hesitancy. Data were analyzed using SPSS version 23 and Minitab version 19. Bivariate analysis was performed by the chi-square test, Odds Ratios (ORs) and statistical significance was accepted when p-value is < 0.05. Only 349 of the survey responses were analyzed in the survey. Results show that 34.70 ± 5.00% of the university community were willing to receive the COVID-19 vaccine when it is offered to them. The COVID-19 hesitancy rate among staff and students was 65.04 ± 5.00%. It was discovered that marital status (OR = 2.06), age (OR = 0.802) and christian denominational affiliation (OR = 0.366) influenced respondents’ perception of COVID-19 vaccination. Gender, occupation, previous vaccination experience, awareness of COVID-19 and previous symptoms of COVID-19 did not significantly (p = 0.05) influence respondents’ willingness to be vaccinated. COVID-19 vaccine hesitancy is high among staff and students in a Nigerian university and is significantly influenced by marital status, respondents’ age and christian denominational affiliation.

Induction of labour is the artificial initiation of labour in a pregnant woman after the age of fetal viability but without any objective evidence of active phase labour and with intact fetal membranes. The need for induction of labour may arise due to a problem in the mother, her fetus or both, and the procedure may be carried out at or before term. Obstetricians have long known that for this to be successful, it is important that the uterine cervix (the neck of the womb) has favourable characteristics in terms of readiness to go into the labour state. To compare Bishop score with any other method for assessing pre-induction cervical ripening in women admitted for induction of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2015) and reference lists of retrieved studies to identify randomised controlled trials (RCTs). All RCTs comparing Bishop score with any other methods of pre-induction cervical assessment in women admitted for induction of labour. Cluster-RCTs were eligible for inclusion but none were identified. Quasi-RCTs and studies using a cross-over design were not eligible for inclusion. Studies published in abstract form were eligible for inclusion if they provided sufficient information.Comparisons could include the following.1. Bishop score versus transvaginal ultrasound (TVUS).2. Bishop score versus Insulin-like growth factor binding protein-1 (IGFBP-1).3. Bishop score versus vaginal fetal fibronectin (fFN).However, we only identified data for a comparison of Bishop score versus TVUS. Two review authors independently assessed the trials for inclusion, extracted the data and assessed trial quality. Data were checked for accuracy. We included two trials that recruited a total of 234 women. The overall risk of bias was low for the two studies. Both studies compared Bishop score withTVUS.The two included studies did not show any clear difference between the Bishop score and TVUS groups for the following main outcomes: vaginal birth (RR 1.07, 95% CI 0.92 to 1.25, moderate quality evidence), caesarean delivery (RR 0.81, 95% CI 0.49 to 1.34, moderate quality evidence), neonatal admission into neonatal intensive care unit (RR 1.67, 95% CI 0.41 to 6.71, moderate quality evidence). Both studies only provided median data in relation to induction-delivery interval and reported no clear difference between the Bishop and TVUS groups. Perinatal mortality was not reported in the included studies.For the review's secondary outcomes, the need for misoprostol for cervical ripening was more frequent in the TVUS group compared to the Bishop score group (RR 0.52, 95% CI 0.41 to 0.66, two studies, 234 women, moderate quality evidence). In contrast, there were no clear differences between the Bishop scope and TVUS groups in terms of meconium staining of the amniotic fluid, fetal heart rate abnormality in labour, and Apgar score less than seven. Only one trial reported median data on the induction-delivery interval and induction to active phase interval, the trialist reported no difference between the Bishop group and the TVUS group for this outcome. Neither of the included studies reported on uterine rupture. Moderate quality evidence from two small RCTs involving 234 women that compared two different methods for assessing pre-induction cervical ripening (Bishop score and TVUS) did not demonstrate superiority of one method over the other in terms of the main outcomes assessed in this review. We did not identify any data relating to perinatal mortality. Whilst use of TVUS was associated with an increased need for misoprostol for cervical ripening, both methods could be complementary.The choice of a particular method of assessing pre-induction cervical ripening may differ depending on the environment and need where one is practicing since some methods (i.e. TVUS) may not be readily available and affordable in resource-poor settings where the sequelae of labour and its management is prevalent.The evidence in this review is based on two studies that enrolled a small number of women and there is insufficient evidence to support the use of TVUS over the standard digital vaginal assessment in pre-induction cervical ripening. Further adequately powered RCTs involving TVUS and the Bishop score and including other methods of pre-induction cervical ripening assessment are warranted. Such studies need to address uterine rupture, perinatal mortality, optimal cut-off value of the cervical length and Bishop score to classify women as having favourable or unfavourable cervices and cost should be included as an outcome.

Emerging evidence has indicated a negative and disproportionate impact of COVID-19 on Black, Asian, and minority ethnic (BAME) communities. Previous studies have already reported that biological and social risk factors increase disease susceptibility, particularly in BAME communities. Despite frontline workers in ethnic minority communities in the United Kingdom’s National Health Service attempting to quell the pandemic, disproportionate numbers of BAME physicians and other health care workers have died of COVID-19. This unprecedented situation highlights ethical and moral implications, which could further augment the impact of the pandemic on their mental health. While the government attempts to mitigate the rate of virus transmission, certain key factors inadvertently augment the negative impact of the pandemic on the mental health and general well-being of BAME communities. This study examined the available literature to explore the association between, and the wider impact of, COVID-19 on BAME communities. Furthermore, this study aims to raise awareness and provide a deeper insight into current scientific discussions.
