Switching from efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF) to the new bictegravir/ emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) regimen maintained high rates of virological suppression in adults who are living with HIV*, according to a study presented at AIDS 2020.

Among individuals with abdominal obesity, drinking beverages with artificial sweeteners (ASBs) or no sugar (USBs) instead of sugar-sweetened beverages (SSBs) helps lose body weight, a study has found. However, USBs have a more favourable effect on sweet taste preference compared with ASBs.

Pre-exposure prophylaxis (PrEP) containing either long-acting injectable cabotegravir (CAB) or tenofovir/emtricitabine (TDF/FTC) is safe and effective for transgender women (TGW) and cisgender men who have sex with men (MSM), but CAB results in a much lower HIV incidence compared to TDF/FTC, results of the HIV Prevention Trials Network (HPTN) 083 have shown.

Machine learning shows promise in melanoma diagnosis

03 Dec 2019

Artificial intelligence (AI) methods appear to be effective for diagnosing melanoma, as the performance of traditional machine learning for the small dataset of melanoma dermoscopic images shows satisfactory results in a recent study.

AI methods for the classification of melanoma have been studied extensively, but few studies compare these methods under the same standards, according to the investigators.

This study aimed to determine the best AI method for the diagnosis of melanoma. A total of 2,200 dermoscopic images were used for the contrast test. Image segmentations, feature extractions and classifications were carried out in sequence for the assessment of traditional machine learning algorithms. For transfer learning training classification, the investigators used the recent popular convolutional neural network frameworks.

Segmentation performance was the best with the region growing algorithm, with an intersection over union and a false-positive rate of 70.06 percent and 17.67 percent, respectively. Logistic regression showed better classification performance, with a sensitivity and a specificity of 76.36 percent and 87.04 percent, respectively.

In addition, the Inception V3 model (Google, Mountain View, CA, US) had the best performance in deep learning algorithms, with an accuracy of 93.74 percent, a sensitivity of 94.36 percent and a specificity of 85.64 percent.

“[T]he potential for deep learning in the future big data era is enormous,” the investigators claimed.

This study was limited by the absence of division in the severity of melanoma sample used in this experiment and the relatively small dataset for deep learning.
