The Relationship among Patient Satisfaction, Patient Loyalty, and Compliance with Treatment.

This study examined the relationship between patient loyalty and adherence to treatment and evaluated the mediating role of patient satisfaction in this relationship. This study consisted of 386 participants. Correlation and regression analyses were used.

Interaction between hypertension and periodontitis.

Objective: The possible association between hypertension and periodontitis and the effect of hypertension on periodontal treatment were investigated by evaluating salivary and gingival crevicular fluid (GCF) interleukin (IL)-6 and C reactive protein (CRP) levels.

Methods: Forty-two healthy individuals without any previously diagnosed systemic disease [10 periodontally healthy (control) and 10 periodontitis (CP)] and subjects with hypertension [13 periodontally healthy (HP) and 9 with periodontitis (CP + HP)] participated in the study. GCF and saliva samples were obtained at baseline and 4 weeks after Phase I periodontal treatment.

Human NK cells confer protection against HIV-1 infection in humanized mice.

The role of NK cells against HIV-1 infections remains to be elucidated in vivo. While humanized mouse models potentially could be used to directly evaluate human NK cell responses during HIV-1 infection, improved functional development of human NK cells in these hosts is needed. Here, we report the humanized MISTRG-6-15 mouse model, in which NK cells were quick to expand and exhibit degranulation, cytotoxicity, and proinflammatory cytokine production in nonlymphoid organs upon HIV-1 infection but had reduced functionality in lymphoid organs.

Sustained Remission in Rheumatoid Arthritis: Time to Withdraw Treatment?

With increasing numbers of patients with rheumatoid arthritis achieving sustained remission, medication withdrawal is an important consideration to reduce polypharmacy and associated adverse events. An article from the journal Arthritis & Rheumatology (1) explores the treatment withdrawal options for patients on etanercept and methotrexate combination therapies and suggests methotrexate withdrawal has the least impact on disease worsening. There are limitations in the study, including the use of only one disease activity score and no assessment of radiographic progression, but, overall, the article provides a good framework for future studies on treatment withdrawal options and the possibility of medication reduction for patients.
