Online ahead of print.ABSTRACTMalaria remains a major public health problem in Papua New Guinea (PNG) and an important force health protection issue for both PNG and Australian Defence Forces. To investigate the malaria burden in the military and civilians residing on military bases, a cross-sectional survey was conducted in April 2019 at three military bases in Wewak, Manus Island, and Vanimo, PNG. A total of 1,041 participants were enrolled; 235 military personnel from three bases and 806 civilians from Wewak and Vanimo. Polymerase chain reaction (PCR...

Conducting active screening for human African trypanosomiasis with rapid diagnostic tests: The Guinean experience (2016 –2021)

Strategies to detect Human African Trypanosomiasis (HAT) cases rely on serological screening of populations exposed to trypanosomes. In Guinea, mass medical screening surveys performed with the Card Agglutination Test for Trypanosomiasis have been progressively replaced by door-to-door approaches using Rapid Diagnostic Tests (RDTs) since 2016. However, RDTs availability represents a major concern...

Diallel analysis of common bean (Phaseolus vulgaris L.) genotypes for seed dietary fibre, carbohydrate, calcium and phosphorus contents
J Appl Genet. 2024 Feb 14. doi: 10.1007/s13353-024-00834-7. Online ahead of print.ABSTRACTGenetic information of bean seed traits can be an immense help to the breeder in selection of suitable genotypes and the appropriate breeding strategies. Therefore, the investigation aims to assess the genetic variability and to elucidate the genetic analysis of seed dietary fibre, carbohydrate, seed calcium and phosphorus contents of Phaseolus vulgaris in the high Guinean Savannah zone conditions. 5 × 5 half-diallel crosses of these traits were conducted in randomized complete block design with three replications.

Liberty ship sinking disrupts military medical mobilisation in 1942
Medical mobilisation is vital to support tropical campaigns where many disease casualties are expected. Much of the medical supplies and equipment for nine station and three general hospitals that were being placed in Australia were aboard the Liberty Ship SS Rufus King when it went aground off Moreton Island on 7 July 1942. A concerted salvage operation rescued 85% of the stores from the freighter that had broken in half on the Amity sandbar. This emergency effort allowed medical support to New Guinea to proceed without delays due to medical supplies that were nearly lost at sea. (Source: Journal of the Royal Army Medical Corps)

Low genetic diversity of < i > Treponema pallidum < /i > ssp. < i > pertenue < /i > (TPE) isolated from patients ’ ulcers in Namatanai District of Papua New Guinea: Local human population is infected by three TPE genotypes
by Monica Medappa, Petra Posp íšilová, Maria Paula M. Madruga, Lucy N. John, Camila G. Beiras, Linda Grillová, Jan Oppelt, Arka Banerjee, Marti Vall-Mayans, Oriol Mitjà, David Šmajs
Yaws is an endemic disease caused byTreponema pallidum subsp.pertenue (TPE) that primarily affects children in rural regions of the tropics. The endemic character of yaws infections and the expected exclusive reservoir of TPE in humans opened a new opportunity to start a yaws eradication campaign. We have developed a multi-locus sequence typing (MLST) scheme for TPE isolates combining the previously published (TP0548, TP0488) and new (TP...

Kids with chattier parents are more talkative, may have bigger vocabulary
Why do some children learn to talk earlier than others? Linguists have pointed to everything from
socioeconomic status
to gender to the number of languages their parents speak. But a new study finds a simpler explanation.
An analysis of nearly 40,000 hours of audio recordings from children around the world suggests
kids speak more when the adults around them are more talkative, which may also give them a larger vocabulary early in life
. Factors such as social class appear to make no difference, researchers report this month in the
Proceedings of the National Academy of Sciences...

Can incorporating genotyping data into efficacy estimators improve efficiency of early phase malaria vaccine trials?
CONCLUSIONS: The power gain from the genotyping methods depends on the context. Because input parameters for early phase power calculations are often uncertain, these estimators are not recommended as primary endpoints for small trials unless supported by targeted data analysis.TRIAL REGISTRATIONS: NCT00866619, NCT02663700, NCT02143934.PMID:38115002 | DOI:10.1186/s12936-023-04802-0 (Source: Cancer Control)

Viruses, Vol. 16, Pages 7: Genomic Analysis of Sindbis Virus Reveals Uncharacterized Diversity within the Australasian Region, and Support for Revised SINV Taxonomy
In this study, we conducted whole genome sequencing of 66 SINV isolates sampled between 1960 and 2014 from countries of the Australasian region: Australia, Malaysia, and Papua New Guinea. G2 viruses were the most frequently and widely sampled, with three distinct sub-lineages defined. No new G6 SINV were identified, confirming geographic restriction of these viruses to south-western Australia. Comparison with global SINV characterized large-scale nucleotide and amino acid sequence divergence between African&ndash;European G1 viruses and viruses that circulate in Australasia (G2 and G3) of up to 26.83% and 14.55%, r...
