Lights, Camera, Action
Lights: Our research activities in 2019 are unfolding in three settings: Ndirande Health Centre in Blantyre, the Paediatric Research Ward at the Queen Elizabeth Central Hospital and out in “the districts”: Namanolo Health Centre (in Balaka District) and Ntaja Health Centre (in Machinga District). In each setting, auxiliary power supplies are required to “keep the lights on” at all times. In the districts, we are based in small health centres — increasingly, those are powered via solar, but we maintain backup generators to keep reagents cold in the fridge, samples safely stored in the freezers, and to illuminate our central offices. The Huckle/Harrison generator continues to perform beautifully at the MSU House — the ESCOM power typically cuts out as we are preparing breakfast or supper, so to hear the generator kick into action is fantastic! The Research Ward is in a privileged position because our backup generator belongs to the Malawi/Liverpool/Wellcome Trust Clinical Research Programme — when the hospital lacks power (which is rare, but it does happen), the pediatric patients requiring oxygen and CPAP are rushed over to our wards.
Camera: Through yet another series of serendipitous events, we have established a collaboration with Vision Quest Biomedical, LLC. They are interested in computer-supported algorithms applied to fundus photos. They’ve rolled out software and portable cameras to help with the diagnosis of diabetic retinopathy and, over the past three years, they’ve turned their attention to developing algorithms to recognize malarial retinopathy. I didn’t think they could do it, but they have — the cameras and software work well in our hands on the Research Ward, so we are rolling the activities out to include the six district/mission referral hospitals with whom we’ve been working over the past two years (they send CM patients in to the Research Ward to help sustain enrollment into our clinical trial). The teams at the six hospitals are very excited to expand their research capacity, With Dr. Gilberto Zamora (Vision Quest) and Mr. Lameck Khonde (Study Coordinator), we visited all six hospitals and provided introductory training with the cameras during the last week of April
Action: We are capturing lots of action with all kinds of new gadgets this year:
• Transcranial Doppler (TCD): Bob Garvey helped us buy a TCD machine from Neural Analytics (building on a long-term relationship with Dr. Robert Hamilton, Chief Scientific Officer at Neural Analytics). Drs. Nicole O’Brien and Yudy Fonseca have trained three members of the Malaria Project team (Bertha Chikaonda, Benard Montfort Gushu and Tusakire Phiri) to capture the TCD parameters on all patients enrolled in the ongoing clinical trial, “Treating Brain Swelling.” It’s early, but TCD appears to be very promising.
• Heart rate variability (HRV): Using yet another gadget, Dr. Gavin Wooldridge is capturing data on HRV, in conjunction with Drs. Allan Doctor and Phyllis Stein from Washington University in St. Louis. We are looking for markers of increased brain volume, and disruptions of the autonomic nervous system, reflected in decreased HRV, may be helpful.
• Optic nerve sheath diameter (ONSD): This is not exactly “action,” as it is a static ultrasound image, but it may be a way of detecting raised intracranial pressure without having to use an MRI.
Our interventional clinical trial, “Treating Brain Swelling in Pediatric Cerebral Malaria,” is going well — we are keeping “Old Faithful,” the 0.35T MRI donated by General Electric Healthcare in 2008, up and running. What a workhorse! We’ve been randomizing cerebral malaria patients with increased brain volume to one of two arms (“usual care” or “immediate ventilatory support”) to date. We have been working closely with the Malawi equivalent of the FDA, the Malawi Pharmacy, Medicine and Poisons Board, to allow an osmotic agent, 3% hypertonic saline, to be imported into Malawi. Once we have secured that permission, we will introduce the third arm. Watch this space!
March for Science: will be part of the international “Day of Action” and will focus on climate change as it pertains to the floods in the Lower Shire. Likely to include a screening of “The Boy Who Harnessed the Wind.”
World Malaria Day will mark the 11th anniversary of the arrival of Malawi’s only MRI in 2008 (a.k.a, Old Faithful).
A series of fortunate events
The 2019 malaria season is the second year of our clinical trial — enrollment is slow because malaria control efforts in Malawi are working: more children are being diagnosed and treated earlier in their illness, so we are seeing many fewer patients at “Queens.” We’re all thrilled, of course, but it does add to the challenge of carrying out the clinical trial
During the malaria season of 2011, we carried out a pilot study of a new-ish imaging technique, transcranial Doppler ultrasound (TCD). It is similar to any other kind of ultrasound — a probe is placed on the skin and records information. In this case, it is information about blood flow velocity, and if the probe is placed properly, we learn about blood flow into and out of the brain.
Back in 2011, the equipment was large, clunky and finicky — but it was clear that the approach was useful. We could see distinctly different wave patterns in different patients.
The technology has improved greatly, now. The equipment can be carried in a backpack, acquiring the wave forms is easily taught to ancillary health personnel, and the “post-processing” of the wave forms has become much more sophisticated. We thought that combining all we are learning about the patients in the clinical trial with the additional information provided by the TCD machine would be very helpful in understanding why the brains become swollen in some children with cerebral malaria.
There were two stumbling blocks: acquiring a machine, and involving a TCD expert. I was telling Bob Garvey of the Warm Hearts Foundation (the co-host of this summer’s Malawi Update at the Garvey Barn) about the machine during the summer of 2017. He realized how much we might learn from adding it in to our routine assessent of patients — and he offered to buy a TCD machine, through the foundation. ZIKOMO!!
At the SAME TIME, summer of 2017, one of our new colleagues on the clinical trial, the aptly named Dr. Allan Doctor, of Washington University in St. Louis (his med school nametag read “A. Doctor”) was professor for a day at Ohio State University. When he mentioned that he was working on a cerebral malaria project in Malawi, he was immediately introduced to Dr. Nicole O’Brien, an adult and pediatric critical care specialist who had established a research capacity in the Democratic Republic of Congo. As it happened (you can’t make this stuff up …), Dr. O’Brien had just finished a large study using TCD on cerebral malaria patients in Congo. Dr. Doctor arranged for Dr. O’Brien to present her work to our group and we were wowed (check it out for yourself: O’Brien N, et al., Pediatr. 2018 Sep 14. pii: S0022-3476(18)31074-6.8).
Dr. O’Brien has visited Malawi several times already and — serendipity alert — when I was talking about her work with our NIH program officer at the American Society of Tropical Medicine and Hygiene annual meeting a year ago, he suggested I write a supplement to our grant to support her research with us. The supplemental grant was awarded and as a result, Dr. O’Brien will be able to spend four months in Malawi during each of the next four malaria seasons.

Good info, brisk breeze at Malawi Update gathering
We had a good turnout at the Malawi Update gathering in Traverse City in early August. Thank you so much to everyone who came; it was so nice to see you, to catch up and share our news with all of you. We had a slide show looping, a couple posters and lots of Blantyre Malaria Project and MSU employees on hand to talk about science. It wasn’t just the north wind that was invigorating.
