Background: More than 25 million patients have peripheral intravenous (IV) catheters placed each year in US hospitals. Infusion therapy is believed to account for one third of all nosocomial bacteremias.
Methods: We performed a randomized, prospective, controlled study in a university-affiliated hospital to determine whether the use of an IV therapy team decreases peripheral venous catheter-related complications in adult medical patients. Patients were randomized to undergo peripheral catheter insertion and/or maintenance either by the IV team or by medical house staff. A dedicated observer reviewed catheter sites daily; findings were applied to a scoring system to define the severity of complications. Bacteremic complications were reviewed by a physician.
Results: Patients with catheters started by the house staff and maintained by ward nursing staff more often had signs or symptoms of inflammation (21.7%) than did patients with catheters maintained by the IV team (7.9%) (P<.001). Patients monitored by the IV team had a greater mean number of catheters placed per patient than did patients monitored by house staff (2.1 and 1.6, respectively) (P<.01). Three episodes of catheter-related sepsis occurred in house staff patients and none in IV team patients (P=.004).
Conclusions: An IV therapy team significantly reduced both local and bacteremic complications of peripheral IV catheters. Timely replacement of the catheter appeared to be the most important factor in reducing the occurrence of complications.

Primary Antiphospholipid Syndrome Causing Critical Limb Ischemia and Ultimately Amputation in an Otherwise Healthy Young Female.
J Am Podiatr Med Assoc
January 2025
†Arbor-Ypsi Foot and Ankle Centers, Ann Arbor, Michigan.
This case report describes an otherwise healthy 43-year-old female who presented with severe pain, foot drop, and critical limb ischemia to her left foot caused by thrombosis of a peripheral artery secondary to antiphospholipid syndrome. Antiphospholipid syndrome is an autoimmune disease that frequently manifests as recurrent arterial and/or venous thrombotic events, ischemic strokes, and miscarriages. Antiphospholipid syndrome affecting primarily the arteries is less common as compared to venous thrombosis.

Background: Brachiocephalic fistula (BCF) and brachiobasilic fistula (BBF) are autogenous fistulas created in the arm for hemodialysis access. However, despite the differences in anatomy and surgical technique, the existing literature shows no significant statistical difference between the maturation, patency, or complications. We analyzed the outcomes of these two types of arteriovenous fistulas in our subgroup of the Indian population.

Department of General Surgery, the First Affiliated Hospital to Shandong First Medical University & Shandong Provincial Qianfoshan Hospital, Jinan, China.
Background: In general, it is relatively easy to remove peripherally inserted central venous catheter (PICC) by gentle traction without any complications. However, the removal of PICC can be challenging occasionally. If the standard interventions fail to remove the catheter, there are no clear recommendations about what to do.

Department of Respiratory and Critical Care Medicine, Fuyang People's Hospital, Fuyang, 236000, People's Republic of China.
Objective: This study aims to assess the clinical significance of the peripheral blood neutrophil-to-lymphocyte ratio (NLR) in predicting chemotherapy outcomes for patients with small cell lung cancer (SCLC).
Methods: A cohort of 44 patients diagnosed with SCLC between January 2021 to June 2022 at Fuyang People's Hospital was selected for analysis. All patients in this group received a first-line platinum-based doublet chemotherapy regimen.
Background: The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).
Methods: The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing.
