Prevention and management of anaemia in pregnancy: Community perceptions and facility readiness in Ghana and Uganda.

Anaemia is one of the most common conditions in low- and middle-income countries, with prevalence increasing during pregnancy. The highest burden is in Sub-Saharan Africa and South Asia, where the prevalence of anaemia in pregnancy is 41.7% and 40%, respectively. Anaemia in pregnancy can lead to complications such as prematurity, low birthweight, spontaneous abortion, and foetal death, as well as increasing the likelihood and severity of postpartum haemorrhage. Identifying and mitigating anaemia in pregnancy is a public health priority. Here we present a mixed-methods situational analysis of facility readiness and community understanding of anaemia in Ghana and Uganda. Quantitative health assessments (adapted from service availability and readiness assessments) and qualitative key informant interviews (KIIs) with district-level stakeholders, in-depth interviews (IDIs) with maternity staff, and focus group discussions (FGDs) with community members were held in 2021. We carried out facility assessments in nine facilities in Ghana and seven in Uganda. We carried out seven KIIs, 23 IDIs, and eight FGDs in Ghana and nine, 17, and five, respectively, in Uganda. Many good practices and general awareness of anaemia in pregnancy were identified. In terms of bottlenecks, there was broad consistency across both countries. In health facilities, there were gaps in the availability of haemoglobin testing-especially point-of-care testing-staffing numbers, availability of standard operating procedures/guidelines for anaemia in pregnancy, and poor staff attitudes during antenatal care. Amongst community members, there was a need for improved sensitisation around malaria and helminth infections as potential causes of anaemia and provision of education around the purpose of iron and folic acid supplementation for preventing or managing anaemia in pregnancy. Anaemia in pregnancy is a persistent challenge, but one with clear opportunities to intervene to yield improvements.

Decoding Covid-19 with the SARS-CoV-2 Genome.

PURPOSE OF REVIEW: SARS-CoV-2, the recently emerged coronavirus (CoV) that is responsible for the current global pandemic Covid-19, first appeared in late 2019 in Wuhan, China. Here, we summarise details of the SARS-CoV-2 genome to assist understanding of the emergence, evolution and diagnosis of this deadly new virus. RECENT FINDINGS: Based on high similarities in the genome sequences, the virus is thought to have arisen from SARS-like CoVs in bats but the lack of an intermediate species containing a CoV with even greater similarity has so far eluded discovery. The critical determinant of the SARS-CoV-2 genome is the spike (S) gene encoding the viral structural protein that interacts with the host cell entry receptor ACE2. The S protein is sufficiently adapted to bind human ACE2 much more readily than SARS-CoV, the most closely related human CoV. SUMMARY: Although the SARS-CoV-2 genome is undergoing subtle evolution in humans through mutation that may enhance transmission, there is limited evidence for attenuation that might weaken the virus. It is also still unclear as to the events that led to the virus' emergence from bats. Importantly, current diagnosis requires specific recognition and amplification of the SARS-CoV-2 RNA genome by qPCR, despite these ongoing viral genome changes. Alternative diagnostic procedures relying on immunoassay are becoming more prevalent.

HIV-1 Nef control of cell signalling molecules: multiple strategies to promote virus replication.

HIV-1 has at its disposal numerous proteins encoded by its genome which provide the required arsenal to establish and maintain infection in its host for a considerable number of years. One of the most important and enigmatic of these proteins is Nef. The Nef protein of HIV-1 plays a fundamental role in the virus life cycle. This small protein of approximately 27 kDa is required for maximal virus replication and disease progression. The mechanisms by which it is able to act as a positive factor during virus replication is an area of intense research and although some controversy surrounds Nef much has been gauged as to how it functions. Its ability to modulate the expression of key cellular receptors important for cell activation and control signal transduction elements and events by interacting with numerous cellular kinases and signalling molecules, including members of the Src family kinases, leading to an effect on host cell function is likely to explain at least in part its role during infection and represents a finely tuned mechanism where this protein assists HIV-1 to control its host.
