Status and influencing factors of patients with kinesiophobia after insertion of peripherally inserted central catheter: A cross-sectional study

This study aimed to investigate the current status and influencing factors of kinesiophobia in patients after insertion of peripherally inserted central catheter (PICC).A total of 240 patients with PICC were included. Their postinsertion status and influencing factors were investigated using the general information questionnaire, Tampa Scale of Kinesiophobia (TSK), Medical Coping Modes Questionnaire, Numerical Rating Scale, and Self-rating Anxiety Scale.The mean TSK score was 36.49 ± 4.19 points, and 89 patients (37.08%) had kinesiophobia. Multiple linear regression analysis showed that factors such as education level, age, monthly income level, catheterization history, face, pain level, anxiety, and number of needle insertions influenced postoperative kinesiophobia in patients with PICC (P < .05). The total variation in the TSK score was 71.8%.The incidence of kinesiophobia was relatively high after PICC insertion. The medical staff needs to undertake targeted intervention measures to help minimize kinesiophobia after PICC insertion, allowing patients to perform scientifically correct functional exercises and attain physical recovery.

Un tratamiento nuevo para una enfermedad antigua: tratamiento de la hipertensión arterial resistente mediante denervación simpática renal percutánea

Hypertension is a major contributor to cardiovascular events, such as stroke and myocardial infarction, with accelerated sympathetic nerve activity implicated in its pathogenesis. However, hypertension in many patients is not adequately controlled, despite the availability of numerous medication classes. Novel procedure—as well as device-based strategies, such as percutaneous renal sympathetic nerve denervation therapy—have been developed to improve blood pressure in these refractory patients. Renal sympathetic denervation delivers not only a decrease in blood pressure levels but also renal as well as systemic sympathetic nerve activity. The reduction in blood pressure appears to be sustained over 3 years after the procedure, which implies no counterregulatory mechanism or re-innervation of afferent renal sympathetic nerve so far. Renal sympathetic denervation is expected to be a promising treatment for patients with hypertension, congestive heart failure, chronic kidney disease, and metabolic syndrome implicated in the pathogenesis of potentiated sympathetic nerve activity. This review will focus on the current devices and procedures, their outcomes and prospects in the treatment of hypertension.     

Use of Oral DDT in Three Human Barbiturate Intoxications: Hepatic Enzyme Induction by Reciprocal Detoxicants

Abstract

In the management of intoxications, the major goals are enhanced elimination of the toxin from the organism and prevention of further absorption. Absorption of an orally administered substance from the gastrointestinal tract can be decreased by adequate washing of the stomach. Delayed absorption of the substance from the small intestine cannot be avoided by this procedure and after the gastric lavage, a nonspecific adsorbent must be administered and diarrhea induced (1). This study demonstrates that iatrogenic diarrhea via gut lavage can also eliminate toxins already absorbed by the body.     

Bispecific antibodies engage T cells for antitumor immunotherapy

Introduction: Although considerable evidence supports the hypothesis that T cells play a critical role in the immune response against cancer, the ability to mount and sustain tumor-specific cellular responses in vivo remains a challenge. A strategy that harnesses the cytotoxic advantage of T cell therapy is the use of bispecific antibodies designed to engage and activate endogenous polyclonal T cell populations via the CD3 complex, but only in the presence of a tumor antigen. While antibody constructs with dual specificity were first described as anticancer therapeutics over 25 years ago, it was not until recently that one subclass of bispecific single-chain antibody, the bispecific T cell engager (BiTE), emerged as superior to previous iterations in achieving efficacy in animal models and early clinical trials.

Areas covered: The evolution of bispecific antibodies in antitumor immunotherapy is reviewed and the greatest hurdles impeding their clinical translation are discussed, specifically in the context of immunoprivileged sites as is the case for intracerebral malignancy.

Expert opinion: The BiTE platform has great potential in the treatment of malignant disease. Despite burgeoning interest in bispecific antibodies and permutations thereof, the issues of stability and cost-effective production persist as obstacles.     

Antibiotic-lock therapy: a clinical viewpoint

Antibiotic lock therapy (ALT) – instillation of high concentrations of anti-microbial agent with or without anti-coagulant into the lumen of central venous catheters – is considered a valid conservative treatment for catheter-related bloodstream infection (CRBSI) in patients highly dependent on maintaining the catheter. Results from randomized controlled studies have indicated that the effectiveness of ALT is moderate, but recent findings from experimental studies and observational case series point to considerable efficacy and safety of this therapy, which is usually associated with concomitant systemic treatment. In this article, the current knowledge about ALT for patients with CRBSI is reviewed and discussed, with emphasis on existing controversies and the results obtained according to the various uses of the catheters and the etiologies of infection.
