Acceptability of the power over pain portal among patients awaiting tertiary care consultation: A qualitative study of patients' perceptions.

Objective: Chronic pain affects approximately 7.6 million Canadians and access to care remains an issue. The Power Over Pain (POP) Portal offers immediate access to evidence-based resources ranging from low- (e.

[Analysis of the effectiveness of various methods of rehabilitation of patients with subacromial impingement syndrome].

Introduction: Subacromial impingement syndrome is a common pathology that leads to a persistent decrease in the functioning of the affected limb and, as a consequence, a decrease in the quality of life and work ability of patients. According to various authors, the study of the effectiveness of treatment and rehabilitation of this pathology is quite widely presented in the literature: surgical, including arthroscopic operations, rehabilitation using various factors of physical therapy, manual and other practices. However, the issue of assessing the effectiveness of movement therapy, both alone and in combination with other therapeutic methods, remains relevant.

The state of lead scoring models and their impact on sales performance.

Although lead scoring is an essential component of lead management, there is a lack of a comprehensive literature review and a classification framework dedicated to it. Lead scoring is an effective and efficient way of measuring the quality of leads. In addition, as a critical Information Technology tool, a proper lead scoring model acts as an alleviator to weaken the conflicts between sales and marketing functions.

Spiny chondrichthyan from the lower Silurian of South China.

Modern representatives of chondrichthyans (cartilaginous fishes) and osteichthyans (bony fishes and tetrapods) have contrasting skeletal anatomies and developmental trajectories that underscore the distant evolutionary split of the two clades. Recent work on upper Silurian and Devonian jawed vertebrates has revealed similar skeletal conditions that blur the conventional distinctions between osteichthyans, chondrichthyans and their jawed gnathostome ancestors. Here we describe the remains (dermal plates, scales and fin spines) of a chondrichthyan, Fanjingshania renovata gen.

The oldest gnathostome teeth.

Mandibular teeth and dentitions are features of jawed vertebrates that were first acquired by the Palaeozoic ancestors of living chondrichthyans and osteichthyans. The fossil record currently points to the latter part of the Silurian period (around 425 million years ago) as a minimum date for the appearance of gnathostome teeth and to the evolution of growth and replacement mechanisms of mandibular dentitions in the subsequent Devonian period. Here we provide, to our knowledge, the earliest direct evidence for jawed vertebrates by describing Qianodus duplicis, a new genus and species of an early Silurian gnathostome based on isolated tooth whorls from Guizhou province, China.
