Continuous determination of blood glucose in children admitted with malaria in a rural hospital in Mozambique.
BACKGROUND: Hypoglycaemia is a frequent complication among admitted children, particularly in malaria-endemic areas. This study aimed to estimate the occurrence of hypoglycaemia not only upon admission but throughout the first 72 h of hospitalization in children admitted with malaria. METHODS: A simple pilot study to continuously monitor glycaemia in children aged 0-10 years, admitted with malaria in a rural hospital was conducted in Southern Mozambique by inserting continuous glucose monitors (CGMs) in subcutaneous tissue of the abdominal area, producing glycaemia readings every 5 min. RESULTS: Glucose was continuously monitored during a mean of 48 h, in 74 children. Continuous measurements of blood glucose were available for 72/74 children (97.3%). Sixty-five of them were admitted with density-specific malaria diagnosis criteria (17 severe, 48 uncomplicated). Five children (7.7%) had hypoglycaemia (<54 mg/dL) on admission as detected by routine capillary determination. Analysing the data collected by the CGMs, hypoglycaemia episodes (<54 mg/dL) were detected in 10/65 (15.4%) of the children, of which 7 (10.8%) could be classified as severe (â€45 mg/dL). No risk factors were independently associated with the presence of at least one episode of hypoglycaemia (<54 mg/dL) during hospitalization. Only one death occurred among a normoglycaemic child. All episodes of hypoglycaemia detected by CGMs were subclinical episodes or not perceived by caregivers or clinical staff. CONCLUSIONS: Hypoglycaemia beyond admission in children with malaria appears to be much more frequent than what had been previously described. The clinical relevance of these episodes of hypoglycaemia in the medium or long term remains to be determined
Changing Trends in P. falciparum Burden, Immunity, and Disease in Pregnancy.
BACKGROUND: Prevention of reinfection and resurgence is an integral component of the goal to eradicate malaria. However, the adverse effects of malaria resurgences are not known. METHODS: We assessed the prevalence of Plasmodium falciparum infection among 1819 Mozambican women who delivered infants between 2003 and 2012. We used microscopic and histologic examination and a quantitative polymerase-chain-reaction (qPCR) assay, as well as flow-cytometric analysis of IgG antibody responses against two parasite lines. RESULTS: Positive qPCR tests for P. falciparum decreased from 33% in 2003 to 2% in 2010 and increased to 6% in 2012, with antimalarial IgG antibody responses mirroring these trends. Parasite densities in peripheral blood on qPCR assay were higher in 2010-2012 (geometric mean [±SD], 409±1569 genomes per microliter) than in 2003-2005 (44±169 genomes per microliter, P=0.02), as were parasite densities in placental blood on histologic assessment (50±39% of infected erythrocytes vs. 4±6%, P<0.001). The malaria-associated reduction in maternal hemoglobin levels was larger in 2010-2012 (10.1±1.8 g per deciliter in infected women vs. 10.9±1.7 g per deciliter in uninfected women; mean difference, -0.82 g per deciliter; 95% confidence interval [CI], -1.39 to -0.25) than in 2003-2005 (10.5±1.1 g per deciliter vs. 10.6±1.5 g per deciliter; difference, -0.12 g per deciliter; 95% CI, -0.67 to 0.43), as was the reduction in birth weight (2863±440 g in women with past or chronic infections vs. 3070±482 g in uninfected women in 2010-2012; mean difference, -164.5 g; 95% CI, -289.7 to -39.4; and 2994±487 g vs. 3117±455 g in 2003-2005; difference, -44.8 g; 95% CI, -139.1 to 49.5). CONCLUSIONS: Antimalarial antibodies were reduced and the adverse consequences of P. falciparum infections were increased in pregnant women after 5 years of a decline in the prevalence of malaria.

Community perceptions of pre-eclampsia and eclampsia in southern Mozambique
Background:
Sub-Saharan Africa has the highest maternal mortality ratio at 500 deaths per 100,000 live births. In Mozambique maternal mortality is estimated at 249-480 per 100,000 live births and eclampsia is the third leading cause of death. The objective of this study was to describe the community understanding of pre-eclampsia and eclampsia, as a crucial step to improve maternal and perinatal health in southern Mozambique.
Methods:
This qualitative study was conducted in Maputo and Gaza Provinces of southern Mozambique. Twenty focus groups were convened with pregnant women, partners and husbands, matrons and traditional birth attendants, and mothers and mothers-in-law. In addition, ten interviews were conducted with traditional healers, matrons, and a traditional birth attendant. All discussions were audio-recorded, translated from local language (Changana) to Portuguese and transcribed verbatim prior to analysis with QSR NVivo 10. A thematic analysis approach was taken.
Results:
The conditions of âpre-eclampsiaâ and âeclampsiaâ were not known in these communities; however, participants were familiar with hypertension and seizures in pregnancy. Terms linked with the biomedical concept of pre-eclampsia were high blood pressure, fainting disease and illness of the heart, whereas illness of the moon, snake illness, falling disease, childhood illness, illness of scaresand epilepsy were used to characterizeeclampsia. The causes of hypertension in pregnancy were thought to include mistreatment by in-laws, marital problems, and excessive worrying. Seizures in pregnancy were believed to be caused by a snake living inside the womanâs body. Warning signs thought to be common to both conditions were headache, chest pain, weakness, dizziness, fainting, sweating, and swollen feet.
Conclusion:
Local beliefs in southern Mozambique, regarding the causes, presentation, outcomes and treatment of pre-eclampsia and eclampsia were not aligned with the biomedical perspective. The community was often unaware of the link between hypertension and seizures in pregnancy. The numerous widespread myths and misconceptions concerning pre-eclampsia and eclampsiamay induceinappropriatetreatment-seeking and demonstrate a need for increased community education regarding pregnancy and associated complications.

Highlighting the burden of malarial infection and disease in the neonatal period: making sense of different concepts
Case report: Rapid HIV progression during acute HIV-1 subtype C infection in a mozambican patient with atypical seroconversion
Acute human immunodeficiency virus (HIV) infection (AHI) refers to the period between viral transmission and development of an adaptive immune response to HIV antigens (seroconversion) usually lasting 6â8 weeks. Rare cases have been described in which HIV-infected patients fail to seroconvert and instead, develop rapid HIV-mediated clinical decline. We report the case of a Mozambican woman with AHI and malaria coinfection who showed atypical seroconversion and experienced rapid deterioration and death within 14 weeks of diagnosis with AHI. Atypical seroconversion may be associated with rapid progression. Fourth generation rapid tests could lead to earlier identification and intervention for this vulnerable subgroup

Prevalence of molecular markers of resistance to sulfadoxineâpyrimethamine before and after community delivery of intermittent preventive treatment of malaria in pregnancy in sub-Saharan Africa: a multi-country evaluation
International audienceBackground Intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxineâpyrimethamine isrecommended at each antenatal care clinic visit in high-moderate transmission areas. However, its coverage remainsunacceptably low in many countries. Community health workers can effectively deliver malaria preventive interventions.The aim of this study was to assess the effect of community delivery of IPTp (C-IPTp) on antenatal care and IPTpcoverage.Methods A community-based IPTp administration approach was implemented in four sub-Saharan countries: theDemocratic Republic of the Congo (DR Congo), Madagascar, Mozambique, and Nigeria. A quasi-experimental beforeand after evaluation by cluster sampling was designed where C-IPTp was implemented in selected country areas indifferent phases. Baseline (before C-IPTp implementation), midline, and endline household surveys were carried outto assess IPTp intake in pregnant women in 2018, 2019, and 2021. Eligible participants of the household survey werewomen of reproductive age (13â50 years old, depending on the country) that had a pregnancy that ended (anypregnancy regardless of pregnancy outcome) in the 6 months before the interview. For the first baseline surveys, thetarget population was women who had a pregnancy that ended in the 12 months before the interview. The primaryoutcome from the household surveys was the proportion of women who reported having received at least three dosesof IPTp during pregnancy. The trial is registered at ClinicalTrials.gov, NCT03600844.Findings A total of 32 household surveys were conducted between March 15, and Oct 30, 2018, and data from18 215 interviewed women were analysed. The coverage of at least three doses of IPTp (IPTp3+) increased after thefirst year of C-IPTp implementation in all project areas in DR Congo (from 22â5% [170/755] to 31â8% [507/1596]),Madagascar (from 17â7% [101/572] to 40â8% [573/1404]), and Nigeria (from 12â7% [130/1027] to 35â2% [423/1203]),with increases between 145â6% (Madagascar) and 506â6% (Nigeria). IPTp3+ coverage increased between baselineand endline in all districts, except for Murrupula (Mozambique) and ranged between 9â6% and 533â6%. This patternwas similar in DR Congo, Madagascar, and Nigeria, and in Mozambique, the increase was lower than the othercountries. Antenatal care attendance did not change or increased lightly in all study countries.Interpretation C-IPTp was associated with an increase in IPTp uptake without reducing antenatal care attendance.The strategy might be considered for malaria control in pregnancy
