Unlocking the potential of novel RTS, S/AS01, and R21/Matrix-M™ malaria vaccines in African nations

Introduction

Mass malaria vaccination, rather than vaccinating only children below age 5, has been proven to have the potential to reduce morbidity and mortality among those vaccinated, both young and old. Addressing vaccine scepticism and misinformation is crucial in African nations to build public trust in malaria prevention. Therefore, including a wider range of demographics in vaccine trials is necessary for equitable representation and achieving herd immunity against malaria.

Aim

This present article aims to identify some of the obstacles that impede malaria vaccination usage and acceptability in African Nations in combating malaria in the region as it continues to pose a significant global public health problem.

Methodology

A literature search was done on the Malaria vaccine between 2000 and 2023. Past and present articles/studies on this topic were consulted on PubMed, Google Scholar, Scopus and Web of Science using the following keywords; "Malaria," "Vaccines," "African Nations," "Obstacles, Strategies," and "Public Health."

Results

The recently approved RTS, S/AS01, and R21/Matrix-M™ Malaria vaccines have the potential to prevent numerous deaths and cases of Malaria in Africa. These vaccines Malaria vaccines are cost-effective in African areas with moderate to high plasmodium falciparum and can be delivered through routine immunization.

Conclusion

To combat malaria effectively in African Nations, African leaders need to set up a comprehensive approach that involves; prevention, healthcare access, implementation research strategies towards adoption and acceptance of malaria vaccines in Africa as well as community engagement with the religious leaders, the market women, community heads, schools, as well as students' union towards the willingness and acceptability of the malaria vaccines among the African populations.

The Effect of Music on Operative Anxiety markers in patients undergoing Cataract Surgery: Adual centre cross-sectional comparative study

OBJECTIVE

To determine the effect of intraoperative music on various markers of anxiety among adult patients undergoing small incision cataract surgery.

METHODS

This was a hospital-based, age-sex matched, comparative cross-sectional study of consenting 144 adult participants aged 46 years and above with operable, age-related cataracts undergoing small incision cataract surgery under local anaesthesia in two ophthalmic centres. All participants were allotted into two equal groups consisting of 72 participants in the experimental group (exposed to music of their choice) and 72 participants in the control group (no music exposure). Blood pressure, pulse rate and salivary cortisol assay levels were measured. Data obtained were analyzed using statistical package for social sciences (IBM SPSS version 23.0).

RESULTS

One hundred and forty-four participants with total male-to-female ratio of 1:2.1 were studied. Gender ratio was 1:2.3 and 1:2.0 and the median age (Q1-Q3) of 65.00 (55.5-71.5) years and 65.50 (56.5-72.0) years for music and non-music groups respectively. Participants in the music group showed a statistically significant reduction in systolic blood pressure, diastolic blood pressure and pulse rate (p < 0.05) except at baseline. The mean value salivary cortisol level showed a statistically significant decrease in both groups from baseline for music (23.91ng/ml) and nonmusic (19.12ng/ml) group (p<0.001) respectively. Similarly, participants in the music group showed a statistically significant reduction of Spielberger State anxiety score after music intervention compared to control (p<0.001).

CONCLUSIONS

This study demonstrated the effectiveness of music in decreasing anxiety indicators during cataract surgery with markers like salivary cortisol assay, pulse rate, systolic and diastolic blood pressure.
