Prevention of violence against women and girls: A cost-effectiveness study across 6 low- and middle-income countries

BackgroundViolence against women and girls (VAWG) is a human rights violation with social, economic, and health consequences for survivors, perpetrators, and society. Robust evidence on economic, social, and health impact, plus the cost of delivery of VAWG prevention, is critical to making the case for investment, particularly in low- and middle-income countries (LMICs) where health sector resources are highly constrained. We report on the costs and health impact of VAWG prevention in 6 countries.Methods and findingsWe conducted a trial-based cost-effectiveness analysis of VAWG prevention interventions using primary data from 5 randomised controlled trials (RCTs) in sub-Saharan Africa and 1 in South Asia. We evaluated 2 school-based interventions aimed at adolescents (11 to 14 years old) and 2 workshop-based (small group or one to one) interventions, 1 community-based intervention, and 1 combined small group and community-based programme all aimed at adult men and women (18+ years old). All interventions were delivered between 2015 and 2018 and were compared to a do-nothing scenario, except for one of the school-based interventions (government-mandated programme) and for the combined intervention (access to financial services in small groups). We computed the health burden from VAWG with disability-adjusted life year (DALY). We estimated per capita DALYs averted using statistical models that reflect each trial’s design and any baseline imbalances. We report cost-effectiveness as cost per DALY averted and characterise uncertainty in the estimates with probabilistic sensitivity analysis (PSA) and cost-effectiveness acceptability curves (CEACs), which show the probability of cost-effectiveness at different thresholds. We report a subgroup analysis of the small group component of the combined intervention and no other subgroup analysis. We also report an impact inventory to illustrate interventions’ socioeconomic impact beyond health. We use a 3% discount rate for investment costs and a 1-year time horizon, assuming no effects post the intervention period. From a health sector perspective, the cost per DALY averted varies between US$222 (2018), for an established gender attitudes and harmful social norms change community-based intervention in Ghana, to US$17,548 (2018) for a livelihoods intervention in South Africa. Taking a societal perspective and including wider economic impact improves the cost-effectiveness of some interventions but reduces others. For example, interventions with positive economic impacts, often those with explicit economic goals, offset implementation costs and achieve more favourable cost-effectiveness ratios. Results are robust to sensitivity analyses. Our DALYs include a subset of the health consequences of VAWG exposure; we assume no mortality impact from any of the health consequences included in the DALYs calculations. In both cases, we may be underestimating overall health impact. We also do not report on participants’ health costs.ConclusionsWe demonstrate that investment in established community-based VAWG prevention interventions can improve population health in LMICs, even within highly constrained health budgets. However, several VAWG prevention interventions require further modification to achieve affordability and cost-effectiveness at scale. Broadening the range of social, health, and economic outcomes captured in future cost-effectiveness assessments remains critical to justifying the investment urgently required to prevent VAWG globally.

In a cost-effectiveness study, Dr. Giulia Ferrari and colleagues examine the costs and health impact of prevention of violence against women and girls in six low- and middle-income countries.     

Seasonality of births in South-Eastern Nigeria.

A study of seasonal pattern of births in Nigeria was conducted using data on live births for the period 1971-76 from 4 climatically similar southeastern states (Anambra, Imo, Cross River and Rivers State). After pooling the data, the monthly distribution for different years was calculated. The resulting time series was graphically compared with temperature levels during time of conception, or nine months back. Data analysis revealed a seasonal pattern in the monthly distribution of births, with the peak period observed during April-June, and a trough during November-January. Counting 9 months back, the conceptions were calculated as occuring during July, August, or September of the previous year. In terms of the annual agricultural cycle of the southeastern states, July-September corresponded with the period of light farm work or relative idleness for men (main activity during this period is weeding and tending the crops, tasks primarily done by women and children); this is also a period of abundance of fruits, vegetables and palm wine, and rains after dusk, conditions conducive to mating.     

Do we consider Andermann syndrome in infants with agenesis of corpus callosum

Andermann syndrome is characterized by agenesis of corpus callosum, anterior horn cell disease, a mixed sensory and motor neuropathy, and facial dysmorphism, and is inherited as an autosomal recessive trait. A 7-month-old boy was admitted with developmental retardation. Head control was not gained and he could not sit. He had high arched palate, elongated facies and large angle of the mandible, which were compatible with the Andermann syndrome. Moderate hypotonicity and absent tendon reflexes were also noted. Serum creatine kinase level was normal. Magnetic resonance imaging of the brain showed agenesis of the corpus callosum. Electromyographic examination revealed the presence of both sensory and motor neuropathy. The patient was diagnosed as having the Andermann syndrome according to the clinical and laboratory findings and he is reported due to rare presentation.     

The Urinary Cytokine/Chemokine Signature of Renal Hyperfiltration in Adolescents with Type 1 Diabetes

Objective

Urinary cytokine/chemokine levels are elevated in adults with type 1 diabetes (T1D) exhibiting renal hyperfiltration. Whether this observation extends to adolescents with T1D remains unknown. Our first objective was to determine the relationship between hyperfiltration and urinary cytokines/chemokines in normotensive, normoalbuminuric adolescents with T1D using GFR_cystatin. Our second aim was to determine the relationship between urine and plasma levels of inflammatory biomarkers, to clarify the origin of these factors.

Methods

Urine and serum cytokines/chemokines (Luminex platform) and GFR_cystatin were measured in normofiltering (n = 111, T1D-N, GFR<135 ml/min/1.73 m²) and hyperfiltering (n = 31, T1D-H, GFR≥135 ml/min/1.73 m²) adolescents with T1D (ages 10–16), and in age and sex matched healthy control subjects (HC, n = 59).

Results

We noted significant step-wise increases in urinary cytokine/chemokine excretion according to filtration status with highest levels in T1D-H, with parallel trends in serum analyte concentrations. After adjusting for serum glucose at the time of sampling, differences in urinary cytokine excretion were not statistically significant. Only serum IL-2 significantly differed between HC and T1D (p = 0.0076).

Conclusions

Hyperfiltration is associated with increased urinary cytokine/chemokine excretion in T1D adolescents, and parallel trends in serum cytokine concentration. The GFR-associated trends in cytokine excretion may be driven by the effects of ambient hyperglycemia. The relationship between hyperfiltration, glycemia, and variations in serum and urine cytokine expression and their impact on future renal and systemic vascular complications requires further study.     

A fatal case of cerebellar hypoplasia associated with anterior horn cell disease

A 27-month-old girl was admitted with inability to walk and speak. The pregnancy, labor and delivery were unremarkable. She was the second child of first degree consanguineous parents and the other 5-year-old child was healthy. On physical examination, she could sit without aid. Horizontal nystagmus and bilateral optic atrophy were diagnosed. Moderate hypotonicity and muscle atrophy were noted in the lower extremities, and deep tendon reflexes were found to be brisk. Serum creatine kinase level was normal. Brainstem auditory evoked potential was also bilateral normal. Flash visual evoked potential was found to be prolonged bilaterally. Magnetic resonance imaging of the brain showed severe cerebellar hypoplasia and mild cerebral atrophy. Electromyographic examination was consistent with anterior horn cell disease. Muscle biopsy specimen was unremarkable. Genetic analysis was unremarkable. The patient was diagnosed with cerebellar hypoplasia associated with anterior horn cell disease, which was named as amyotrophic cerebellar hypoplasia, Norman's disease or infantile neuronal degeneration in the literature. During the follow-up, the parents said that she died at the age of 34 months, because of probable infection.     

Synthesis and aggregation phenomena of multifunctional Schiff bases and Ni(II) complexes: an X-ray investigation

Multifunctional Schiff base ligands Lⁿ, namely the tetradentate N,N^′-bis[2-hydroxy-5-(azopyridine)benzylidene]propylendiamine and the bidentate N-dodecyl-5-(azopyridine)salicylaldimine, both containing a flexible azo spacer, a metallation site and a terminal pyridine group, were synthetised and fully characterised. Mesogenic structures, analysed by polarised optical microscopy, DSC and powder X-ray diffraction, were obtained from self-assembly of the mono or bifunctional hydrogen-bond acceptors Lⁿ with carboxylic acid donors. Ni(II) mono and bis-chelate, four- and six-coordinated, Lⁿ derivatives were synthetised. The octahedral structure of the [Ni(py)₂(L²)₂] complex was confirmed by single crystal X-ray analysis. H-bonded self-assembly of Ni(II) complexes and carboxylic acids results in the formation of supramolecular networks whose structure and thermal stability were studied by DSC and powder X-ray diffraction analysis at variable temperatures.     

A novel protein C inhibitor gene mutation in pediatric stroke patients after bone marrow transplantation

Protein C inhibitor is a heparin dependent serine protease inhibitor found in human plasma, urine and other body fluids. It was originally identified as an inhibitor of activated protein C. Stroke is an important cause of morbidity and mortality in the pediatric age group. In this study we analyzed the protein C inhibitor gene mutations in Turkish pediatric stroke patients. We found a missense mutation of G to A at nucleotide 6760 in exon 2, resulting in a transition serine to asparagine (p.Ser188Asp) and in a child and his father and also we found same alteration in exon 2 in an another pediatric stroke case following bone marrow transplantation.     

Toxic hepatitis in a case of Angelman syndrome associated with Lennox-Gastaut syndrome

We report a 26-month-old boy with Angelman syndrome associated with Lennox-Gastaut syndrome, who developed a rash and a persistent toxic hepatitis after lamotrigine was added to valproate therapy. The patient had typical findings of both Angelman and Lennox-Gastaut syndromes. Chromosome analysis performing by FISH analysis showed a deletion in chromosome 15 (q11.2 q11.2). Although some cases of Angelman syndrome associated with Lennox-Gastaut syndrome were reported in the literature, valproate and/or lamotrigine induced toxic hepatitis in Angelman syndrome has hitherto never been described. We conclude that VPA and LTG combination should be given with great caution or avoided in patients with Angelman syndrome.
