Dear Editor, Pitted keratolysis (PK), also known as keratosis plantaris sulcatum, is a non-inflammatory, bacterial, superficial cutaneous infection, characterized by many discrete superficial crateriform ''pits'' and erosions in the thickly keratinized skin of the weight-bearing regions of the soles of the feet (1). The disease often goes unnoticed by the patient, but when it is noticed it is because of the unbearable malodor and hyperhidrosis of the feet, which are socially unacceptable and cause great anxiety to many of the patients...

For an object classification system, the most critical obstacles toward real-world applications are often caused by large intra-class variability, arising from different lightings, occlusion, and corruption, in limited sample sets. Most methods in the literature would fail when the training samples are heavily occluded, corrupted or have significant illumination or viewpoint variations. Besides, most of the existing methods and especially deep learning-based methods, need large training sets to achieve a satisfactory recognition performance...

Face recognition techniques have been developed significantly in recent years. However, recognizing faces with partial occlusion is still challenging for existing face recognizers, which is heavily desired in real-world applications concerning surveillance and security. Although much research effort has been devoted to developing face de-occlusion methods, most of them can only work well under constrained conditions, such as all of faces are from a pre-defined closed set of subjects. In this paper, we propose a robust LSTM-Autoencoders (RLA) model to effectively restore partially occluded faces even in the wild...

Matthew Strider Jeffers, Dale Corbett
BACKGROUND AND PURPOSE: Reach training in concert with environmental enrichment provides functional benefits after experimental stroke in rats. The present study extended these findings by assessing whether intensive task-specific reach training or enrichment initiated alone would provide similar functional benefit. Additionally, we investigated whether the 70% recovery rule, or a combined model of initial poststroke impairment, cortical infarct volume, and rehabilitation intensity, could predict recovery in the single-pellet task, as previously found for the Montoya staircase...

Penile erection is a hemodynamic process consisting of 2 synchronized components in which the first (active) requires proper vascular endothelium functioning, whereas the second one (passive) is based on a veno-occlusive mechanism. Antihypertensive treatment reduces the passive component, often leading to the development of erectile dysfunction (ED), but lifestyle modifications can improve the sexual functioning. The study aimed to evaluate the association between blood pressure (BP) reduction caused by cardiovascular training and the intensity of ED in men with coronary heart disease...

OBJECTIVE Cerebrovascular bypass surgery is a challenging yet important neurosurgical procedure that is performed to restore circulation in the treatment of carotid occlusive diseases, giant/complex aneurysms, and skull base tumors. It requires advanced microsurgical skills and dedicated training in microsurgical techniques. Most available training tools, however, either lack the realism of the actual bypass surgery (e.g., artificial vessel, chicken wing models) or require special facilities and regulations (e...

The optimal exercise modality for the improvement of health-related parameters and microvascular function in obese adolescents is not yet fully understood. Therefore, this study aimed to 1) compare the microvascular phenotype of obese and normal-weight adolescents; and 2) to determine the effects of a lifestyle intervention including three months of moderate continuous training (MCT) or high-intensity interval training (HIIT) on health-related parameters and microvascular function in 29 obese adolescents. Body composition, metabolic profile, aerobic fitness and cutaneous blood flow, measured using laser Doppler flowmetry at rest and during post-occlusive reactive hyperemia, were assessed prior to and following lifestyle intervention...

NEW FINDINGS: What is the central question of this study? Does ischemic preconditioning (IPC) influence central and peripheral fatiguing mechanisms during sustained maximal isometric exercise? What is the main finding and its importance? Voluntary activation and pre- to post-exercise reductions in resting twitch torque values were unchanged by IPC. However, an effect on tissue oxygenation was observed within the IPC trials where greater concentrations of deoxyhaemoglobin were recorded with concurrent upward trends of total haemoglobin concentrations...

BACKGROUND: Due to the increasing threat of terrorist attacks and assassinations even in Europe, the interest in management of severe vascular injuries, which, with an increased incidence of 10% are to be expected with such penetrating wounds, is also growing; however, with increasing subspecialization in surgery there is a threat that the know-how in vascular surgery will become lost among non-vascular surgical specialists. Therefore, the Germany military established an educational program, the so-called DUOplus concept, to ensure that future military surgeons acquire and retain the experience and skills to fulfill the demanding role of a deployed surgeon...

BACKGROUND AND PURPOSE: Driven by the positive results of randomized, controlled trials of endovascular stroke therapies (EVT) in stroke patients with large vessel occlusion, different approaches to speed up the workflow for EVT candidates are currently being implemented worldwide. We aimed to assess the effect of a simple stroke network-wide workflow improvement project, primarily focusing on i.v. thrombolysis, on process times for patients undergoing EVT. METHODS: In 2015, we conducted a network-wide, peer-to-peer acute stroke workflow improvement program for i...

Arterial occlusion pressure (AOP) is typically used to normalize blood flow restriction (BFR) during low intensity BFR exercise. Despite strong evidence for sexual dimorphism in muscle blood flow, sex-related differences in AOP estimation remain a controversial topic. We aimed at determining whether the relationship of upper-limb AOP with arm circumference and systolic blood pressure (BP) differs between men and women resting in the seated position. Sixty-two healthy young participants (31 men: 21.7 ± 2.3; 31 women: 22...

Traditionally the double-lumen-tube (DLT) is considered the gold standard for lung separation. Despite being equally feasible for standard situations, there are special populations and circumstances requiring the use of a bronchial blocker (BB) to establish one-lung ventilation. Children under 8 years of age and patients without a patent orotracheal airway necessitate the use of a bronchial blocker in most cases, as well as those requiring selective lobar blockade or a rapid sequence induction. Surgery with predicted postoperative mechanical ventilation or in tracheotomized patients at least favors their use by avoiding the complications of a tube exchange...
