Congenital arhinia is a life-threatening, rare craniofacial disorder, which, when not identified and managed early can cause severe respiratory distress at birth due to upper airway obstruction. Since neonates are obligate nasal breathers, simultaneous sucking and breathing requirement in neonates with arhinia leads to respiratory distress. Inspiration and expiration through the oral passage alone may result in thoracic retraction, thereby further exacerbating respiratory distress.

Article Synopsis
  • The study investigates damaging mutations in the human genome that may contribute to nonsyndromic cleft lip with or without cleft palate (nsCL ± P), focusing on high-impact mutations in African and Brazilian cohorts.* -
  • Researchers utilized next-generation sequencing (NGS) and whole-exome sequencing to identify pathogenic variants and discovered several damaging mutations in a gene related to cell adhesion, which has a link to cleft palate in mice.* -
  • The findings highlight the significance of the gene encoding AFADIN in the risk for nsCL ± P in humans and emphasize the effectiveness of combining NGS with computational analysis to better understand this condition's genetic basis.*

The majority (85%) of nonsyndromic cleft lip with or without cleft palate (nsCL/P) cases occur sporadically, suggesting a role for de novo mutations (DNMs) in the etiology of nsCL/P. To identify high impact protein-altering DNMs that contribute to the risk of nsCL/P, we conducted whole-genome sequencing (WGS) analyses in 130 African case-parent trios (affected probands and unaffected parents). We identified 162 high confidence protein-altering DNMs some of which are based on available evidence, contribute to the risk of nsCL/P.

Background: In high income countries, guidelines exist recommending gestational age thresholds for offering and obligating neonatal resuscitation for extremely preterm infants. In low- and middle- income countries, this approach may be impractical due to limited/inconsistent resource availability and challenges in gestational dating. Scant literature exists on how clinicians in these settings conceptualize viability or make resuscitation decisions for premature infants.

Background: Early initiation of breastfeeding (EIBF), breastfeeding within first hour after birth, is known to have major benefits for both the mother and newborn. EIBF rates, however, tends to vary between and within countries. This study set out to determine the prevalence of EIBF at the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana, and to evaluate the determinants of EIBF and time to initiation of breastfeeding.

Background: "Kangaroo mother care," a type of newborn care involving skin-to-skin contact with the mother or other caregiver, reduces mortality in infants with low birth weight (<2.0 kg) when initiated after stabilization, but the majority of deaths occur before stabilization. The safety and efficacy of kangaroo mother care initiated soon after birth among infants with low birth weight are uncertain.

Neonatal mortality is one of the leading causes of under-five mortality globally, with the majority of these deaths occurring in low- and middle-income countries. In Ghana, there is a belief in an array of newborn conditions, called Asram, that are thought to have a spiritual, rather than physical, cause. These conditions are predominantly managed by traditional healers as they are considered unable to be treated by allopathic medical providers.

Background: For every newborn who dies within the first month, as many as eight more suffer life-threatening complications but survive (termed 'neonatal near-misses' (NNM)). However, there is no universally agreed-upon definition or assessment tool for NNM. This study sought to describe the development of the Neonatal Near-Miss Assessment Tool (NNMAT) for low-resource settings, as well as findings when implemented in Ghana.

Introduction: Preterm infants make up the majority of the 9 million babies born in Africa and South Asia requiring supplemental feedings as they transition to exclusive breastfeeding. The World Health Organization recommends the use of a cup to feed newborns with breastfeeding difficulties in low-resource settings. We set out to evaluate the Nifty cup, a new feeding cup designed specifically for infants with breastfeeding difficulties.

Article Synopsis
  • Orofacial clefts, including cleft palate only (CPO) and cleft lip with or without palate (CL/P), are prevalent developmental disorders that create various clinical and psychological challenges.
  • In a study involving around 17 million genetic markers among sub-Saharan African populations, researchers identified new genetic loci associated with CPO on chromosomes 2 and 19, suggesting potential biological mechanisms.
  • The study confirmed the significance of previously known loci such as 8q24 for CL/P, along with the replication of other established genes like PAX7 and VAX1, contributing to our understanding of these conditions.

Background: Ghana has achieved significant progress in breastfeeding practices in the past two decades. Further progress is, however, limited by insufficient government funding and declining donor support for breastfeeding programs. The current study pretested feasibility of the in Ghana, to assess the existing enabling environment and gaps for scaling-up effective actions.

Neonatal mortality is a significant problem in many low-resource countries, yet for every death there are many more newborns who suffer a life-threatening complication but survive. These "near-misses" are not well defined, nor are they well understood. This study sought to explore how health care providers at three tertiary care centers in Ghana (each with neonatal intensive care units (NICUs)) understand the term "near-miss.

Article Synopsis
  • Cleft lip and/or cleft palate (CL/P) are facial birth defects influenced by genetic and environmental factors, with significant genetic associations identified mostly in noncoding regions of the genome.
  • The study focused on identifying coding variants in the GREM1 gene by analyzing DNA from 397 individuals with CL/P from sub-Saharan Africa and found two novel variants not present in control groups.
  • Results showed one variant associated with a soft palate cleft and another in a case with a bilateral cleft lip, suggesting regulatory elements, rather than coding variants, may drive the connection between GREM1 and CL/P.

Background: Persons with Disabilities (PWDs) are a unique group that are often overlooked in many developing countries due to systemic weaknesses, lack of political commitment and inadequate support from government and non-governmental agencies. The population of these individuals is however steadily on the increase and currently corresponds to 15 % of the world population. Although much data exist on lifestyle and conditions of prisoners with disabilities in the western world, scanty information is available in Africa.
