Achieving the digital detox.

Over the past few months, during my interaction with various people on Twitter and offline, I have been hearing about the information deluge that makes it impossible for them to acquire new skills. We indeed have limited 24 hours!

I wouldn’t be able to give a blow by blow account of how I manage things, but I have had to stick to certain good habits that have made things more comfortable for me. I will mention a few services below that make it incredibly easy to flow past the flood of distractions.

1) Mobile phone:

This is the biggest annoyance! I am off the social networks on the device barring Telegram. More on that later.

Twitter is accessed only on the browser. No dedicated applications exist. All notifications on the device are blocked except for text messages.

Telegram helps me to mute all conversations except people whom I deem essential. I have a lot of channels where I consume content passively. No mainstream social networks like Facebook or Instagram for me. They are antiquated because I cannot control them.

I also don’t have a fear of missing out. My associates either call me or text me if needed. Android has become better to manage notifications in recent times. I don’t have any experience with iOS, but I remain convinced that Apple iPhones are merely iPods with a calling facility.

2) Email.

I had mentioned this earlier too. I use Fastmail because I find there is inherent value in paying up for the email. I use a lot of aliases whenever I sign up for the service. It helps to signup with a unique email address. For example, for Dropbox, my alias will be dropbox (at) FastMail dot com (it is a hypothetical- just for illustration). Therefore, if any spam flows into my inbox, I know where is the leak from. All I have to do is to delete the alias.

This simple hack has served me well over six years, and I am happy to stay with this service. Mainstream email applications like Gmail or Yahoo are useless.

I have also created extensive rules which directs the email in the trash. It helps to clean up the clutter at the server itself without manual intervention. For example, all newsletters go to trash directly. Some of them are automatically marked as read and stay in the inbox- I scan through them when I get time. When they are marked as read, I don’t get a notification. Therefore, can easily stay focused on my work without being distracted by the flow in the inbox.

3) Password Manager

1Password is the password manager that is my life saver. It generates unique passwords for all the websites. It is a paid service, but good cloud sync helps me to sync it with my Android device as well. It eliminates the need to remember unique passwords.

4) The use of Telegram chat app

Telegram remains the only way to stay connected with any semblance of “social network”. I use a combination of groups and channels to stay informed. Channels work as public broadcasts. Any specific information I need is transmitted to it. I use bots (both paid and free) to achieve the effect.

For example, I use the IFTTT bot to work with the RSS feeds to populate the channels with the Pubmed content. If I need to track, say the latest publications in the development of MR-LINAC, I don’t have to visit the website manually. By use of booleans, I can filter the content, generate the specific RSS feeds which pipes it elegantly in the channel via IFTTT bot. Likewise, I use junction-connection bot and Feed-Reader bot for different purposes. I pool in information from all specific channels I need to follow into one omnibus channel so that I don’t have to deal with a multitude of channels. I do this by using junction-bot on Telegram.

Feed-Reader bot helps me to tap into various other social networks. For example, I have a specific channel devoted to cycling. All posts from multiple Instagram accounts flow in the channel. It helps me to keep track of the sectoral development. Likewise, I developed a channel for journalists on Telegram to keep track of telecom sector and clean energy. I also have a dedicated art channel that I helped to make for a friend. That collects all impressionist art, beautiful nature pictures and graffiti! None of the posts is done manually.

Focused groups require extensive group management. I recommend using Combot because it comes with a beautiful web-interface. Although the community bot management has introduced a paid plan, it is free for groups that have up to 100 members. The bot deletes specific stop words automatically along with other nifty features like muting users. The bot also keeps groups free of spam messages. Therefore, the groups stay efficient, productive and on course. It is unlike WhatsApp where users start spamming others without any rhyme or reason.

This above may sound onerous, but it helps to maximise the efficiency gains. As long as you are not distracted, it helps to keep focused on work.

In the busy schedules that we keep, always find time for solitude. That is the most critical period to stop and reflect on your goals.

Digital tools need a constant refinement. Hopefully, I will update this in the future.

Quality of life in brain tumours

This issue is very thorny one in the neuro-oncology community. How do you measure the quality of life objectively?

A RANO working group has defined that outline and is aware of it. We, as radiation oncologists, aren’t oblivious to the fact that radiation therapy offers one single shot to give the maximum chance of cure. I am not discussing the issue of re-irradiation here, but the idea is to minimise the impact of existing delivery mechanisms.

Beyond the tumour volumes (2-3 cm for high-grade gliomas), this is both empirical and observational. They observed that bulk of failures happened in the high dose region. It brings us to two important questions here.

1) If we know that it is going to happen in the 95% isodose, why don’t we focus on intentional dose heterogeneity, at the expense of conformity? We could explore mathematical formulations for it- how best to predict which dose fractionation would be best suitable for the likely outcomes, where the failure is expected to take place and escalate the dose to that region.

2) Some tumours usually fail elsewhere, outside the treatment area. If this is the case, why not “lower” the dose to the treatment area (so-called “de-escalation”)?

Do you see the immediate impact?

Lower the total dose to the normal brain!

Now, that leads us to two more questions.

1) Why don’t we lower the dose to 55+Gy for Grade III tumours, because they have a better outcome?

2) Does Temozolomide also act as a radiation sensitiser?

The problems with these very broad-based assumptions are that we do not have a robust criterion for pre-operative or even intra-operative validation of tumour subsets by use of MR spectroscopy or perfusion (or use of any other metabolites, for that matter). Likewise, after intense scrutiny and numerous workshops, we have just been able to define the glioblastomas/grade III astrocytomas along with the molecular data (or even other variants) objectively. Previously, palisading necrosis was all that we had from my pathology colleagues. Now, we are wading in molecular soup, and no one has the complete picture of how things can be nailed!

However, use of these molecular methods isn’t widespread.

One way out is to sequence the tumours completely, follow up patients standard course fractionation and prospectively identify patterns of failure.

It would be akin to a very preliminary “precision medicine” and not the hype cycle that seeks to identify the “molecular targets”.

No, we don’t need more “research” on something that is being duplicated across the labs. But we need to be able to channelise something that we have learned.

Who is going to bell the cat?

I think, currently, we are just trying to identify who the cat is.
