Robot surgery fights cancer

Robotic surgery provides better results than conventional procedures in the removal of cancerous prostate glands, new research shows.

Published

In a review of 104 studies, representing almost 230 000 patients and published in the World Journal of Urology recently, researchers analysed the outcomes of robotic-assisted procedures compared to laparoscopic and open retropubic radical prostatectomies (removal of cancerous prostate).

The review looked at major complications, operative time, length of hospital stays, blood loss, transfusions, conversions, rate of post-operative erectile dysfunction and incontinence, cost and positive surgical margin (PSM) which indicates whether the entire extent of the cancer was extracted during the operation.

“For PSM and peri- and post-operative complications, [robotic surgery] demonstrated better results than [open surgery] and laparoscopic radical prostatectomy,” noted the report.

Urologist and robotic surgeon Dr Francois Duvenage said the results echoed the experience at The Urology Hospital, Pretoria. It is the first institution in Africa to obtain a robotic surgical system which has conducted over 1 300 procedures since 2013.

“Robotic-assisted surgery is well known to be minimally invasive with less side effects. This study indicates it may also be able to better control cancer. The aim of the operation is to remove the prostate and all the inherent and surrounding cancer and this research shows that robotic surgery is leading in this regard.”

The review is in line with other research on robotic surgery which shows improved erectile function and urinary continence compared to open surgery.

Just over 4% of all South African men will develop prostate cancer in their lifetime and an average five South African men die from prostate cancer every day.

In addition to prostatectomies, robotic surgery is offered at The Urology Hospital for partial nephrectomies, (removal of cancerous parts of the kidney) and cystectomies (removal of the bladder). It is the only specialised hospital of its kind in SA, comprising 23 urologists, 10 of whom are trained in robotic surgery – the highest concentration of robotic surgeons in the country.

Low-cost wireless sport earphones get a kickstart

Wireless earphone brands are common, but not crowdfunded brands. BRYAN TURNER takes the K Sport Wireless for a run.

Published

on

As wireless technology becomes better, Bluetooth earphones have become popular in the consumer market. KuaiFit aspires to make them even more accessible to more people through a cheaper, quality product, by selling the K Sport Wireless Earphones directly from its Kickstarter page

KuaiFit has an app by the same name which offers voice-guided personal training services in almost every type of exercise, from cardio to weight-lifting. A vast range of connectivity to third-party sensors is available, like heart rate sensors and GPS devices, which work well with guided coaching. 

The app starts off with selecting a fitness level: beginner, intermediate and advanced. Thereafter, one has the ability to connect with real personal trainers via a subscription to its paid service. The subscription comes free for 6 months with the earphones, and R30 per month thereafter. 

The box includes a manual, a USB to two USB Type B connectors, different sized soft plastic eartips and the two earphone units. Each earphone is wireless and connects to the other independently of wires. This puts the K Sport Wireless in the realm of the Apple Earpods in terms of connection style. 

The earphones are just over 2cm wide and 2cm high. The set is black with a light blue KuaiFit logo on the earphone’s button. 

The button functions as an on/off switch when long-pressed and a play/pause button when quick-pressed. The dual-button set-up is convenient in everyday use, allowing for playback control depending on which hand is free. Two connectivity modes are available, single earphone mode or dual earphone mode. The dual earphone mode intelligently connects the second earphone and syncs stereo audio a few seconds after powering on. 

In terms of connectivity, the earphones are Bluetooth 4.1 with a massive 10-meter range, provided there are no obstacles between the device and the earphones. While it’s not Bluetooth 5, it still falls into the Bluetooth Low Energy connection category, meaning that the smartphone’s battery won’t be drastically affected by a consistent connection to the earphones. The batteries within the earphones aren’t specifically listed but last anywhere between 3 and 6 hours, depending on the mode. 

Audio quality is surprisingly good for earphones at this price point. The headset style is restricted to in-ear due to its small design and probable usage in movement-intensive activities. As a result, one has to be very careful how one puts these earphones, in because bass has the potential of getting reduced from an incorrect in-ear placement. In-ear earphones are usually notorious for ear discomfort and suction pain after extended usage. These earphones are one of the very few in this price range that are comfortable and don’t cause discomfort. The good quality of the soft plastic ear tip is definitely a factor in the high level of comfort of the in-ear earphone experience.

Overall, the K Sport Wireless earphones are great considering the sound quality and the low price: US$30 on Kickstarter.

Taxify enters Google Maps

A recent update to Taxify now uses Google Maps which allows users to identify their drivers, find public transport and search for billing options.

People planning their travel routes using Google Maps will now see a Taxify icon in the app, in addition to the familiar car, public transport, walking and billing options.

Taxify started operating in South Africa in 2016 and as of October 2018 operates in seven South African cities – Johannesburg, Ekurhuleni, Tshwane, Cape Town, Durban, Port Elizabeth and Polokwane.

Once riders have searched for their destination and asked the app for directions, Google Maps shares the proximity of cars on the Taxify platform, as well as an estimated fare for the trip.

If users see that taking the Taxify option is their best bet, they can simply tap on the ‘Open app’ icon, to complete the process of booking the ride. Customers without the app on their device will be prompted to install Taxify first.

This integration makes it possible for users to evaluate which of the private, public or e-hailing modes of transport are most time-efficient and cost-effective.

“This integration with Google Maps makes it so much easier for users to choose the best way to move around their city,” says Gareth Taylor, Taxify’s country manager for South Africa. “They’ll have quick comparisons between estimated arrival times for the different modes of transport, as well as fares they can expect to pay, which will help save both time and money,” he added.

Taxify rides in Google Maps are rolling out globally today and will be available in more than 15 countries, with South Africa being one of the first countries to benefit from this convenient service.
