Behavioral Nudges to Encourage Appropriate Antimicrobial Use Among Health Professionals in Uganda.

Antimicrobial resistance (AMR) is a global public health concern exacerbated by inappropriate antimicrobial prescribing practices, particularly in low-resource settings such as Uganda. The research aimed to develop a culturally sensitive behavioral intervention, leveraging a "nudge" strategy, to improve healthcare provider adherence to the 2016 Uganda Clinical Guidelines (UCG 2016) in five Ugandan hospitals. This intervention formed part of broader antimicrobial stewardship initiatives led by the United States Agency for International Development Medicines, Technologies, and Pharmaceutical Services Program.

Establishing Trust in Pharmaceutical Data with an Independent Verification and Validation Methodology.

Our aim is to demonstrate a general-purpose data and knowledge validation approach that enables reproducible metrics for data and knowledge quality and safety. We researched widely accepted statistical process control methods from high-quality, high-safety industries and applied them to pharmacy prescription data being migrated between EHRs. Natural language medication instructions from prescriptions were independently categorized by two terminologists as a first step toward encoding those medication instructions using standardized terminology.

Applications of artificial intelligence (AI) in ovarian cancer, pancreatic cancer, and image biomarker discovery.

Background: Artificial intelligence (AI), including machine learning (ML) and deep learning, has the potential to revolutionize biomedical research. Defined as the ability to "mimic" human intelligence by machines executing trained algorithms, AI methods are deployed for biomarker discovery.

Objective: We detail the advancements and challenges in the use of AI for biomarker discovery in ovarian and pancreatic cancer.

Impact of early dose intensity reduction of Palbociclib on clinical outcomes in patients with hormone-receptor-positive metastatic breast cancer.

Background: Palbociclib is commonly added to an aromatase inhibitor (AI) as first-line therapy in ER + HER2- metastatic breast cancer (MBC). There are no data on the effect of the relative dose intensity (RDI) of palbociclib in first-line setting on clinical outcomes. The objective of this study is to explore the association of RDI and dose reduction of palbociclib in the first-line setting with PFS.

Additional B-cell malignancies in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL).

Family and migration studies suggest a genetic risk of developing chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL). We hypothesized that CLL patients have an increased risk of additional clonally unrelated B-cell malignancies. To test this, we studied 467 CLL patients (2743 person-years (PYs)) at a single institution over 17 years.

Multiple B cell malignancies in patients with chronic lymphocytic leukemia: epidemiology, pathology, and clinical implications.

Chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) is associated with increased risk for certain cancers, but relatively little is known about the risk for these patients to develop additional B cell malignancies. Here, we review the available epidemiological data on multiple B cell malignancies in CLL, discuss diagnostic methods and proper pathologic evaluation to distinguish CLL from other B cell malignancies, and address clinical challenges and unmet needs in caring for CLL patients with unrelated B cell malignancies and disease transformation. Considerations include CLL patients with unrelated monoclonal B cell lymphocytosis, biclonal CLL, secondary B cell non-Hodgkin lymphomas, and Richter syndrome - both clonally related transformation and large B cell lymphoma.

Management of melanoma in patients with chronic lymphocytic leukemia.

Melanoma is significantly more common and is associated with a poorer prognosis in patients with an underlying B-cell malignancy. This study reports on the management of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) and a subsequent diagnosis of melanoma. In the Wilmot Cancer Institute CLL cohort, which includes 470 patients followed for 2849 person-years, 18 patients (3.

The association between early-life relative telomere length and childhood neurodevelopment.

Purpose: To examine the association between telomere length and neurodevelopment in children.

Methods: We examined the relationship between relative telomere length (rTL) and neurodevelopmental outcomes at 9 and 30 months, and 5 years of age in children enrolled in the Seychelles Child Development Study Nutrition Cohort 1 (NC1). Relative telomere length was measured in cord blood and in child blood at age five.

Analysis of the risk of infection in patients with chronic lymphocytic leukemia in the era of novel therapies.

We studied the risk of infections in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL). Major infections were defined as requiring hospital admission or intravenous antimicrobial treatment. Incidence rate (IR) ratios (IRR) were used to compare infection rates.

Interval robotic cytoreduction following neoadjuvant chemotherapy in advanced ovarian cancer.

The objective of this study is to review our experience with robotic interval cytoreduction following neoadjuvant chemotherapy for advanced ovarian cancer. We retrospectively reviewed patients with advanced ovarian cancer treated with neoadjuvant chemotherapy (NAC) and interval robotic cytoreduction (IRC) between 2011 and 2016 at the University of Rochester Medical Center. Demographic information, chemotherapy treatment, operative results, and follow-up were extracted from medical records.

Late Relapses After High-dose Chemotherapy and Autologous Stem Cell Transplantation in Patients With Diffuse Large B-cell Lymphoma in the Rituximab Era.

Background: The standard of care for diffuse large B-cell lymphoma (DLBCL) relapsing after front-line therapy is high-dose chemotherapy and autologous stem cell transplantation (ASCT). Evidence has suggested that early relapses (ie, within 1 year) after this approach portends exceptionally poor outcomes. However, data examining relapses > 1 year after ASCT for patients with refractory or relapsed DLBCL are limited, in particular, in the rituximab era.

Multi-branch renal artery lesions: surgical options and results.

Renovascular lesions affecting more than one primary or secondary renal artery branch represent a challenging therapeutic problem. Over the last 5 years, the authors have treated 20 patients with complex multi-branch renal lesions. The number of renal artery branches per kidney ranged from two to seven.

Carotid artery replacement in conjunction with resection of squamous cell carcinoma of the neck: preliminary results.

Squamous cell carcinoma can invade the carotid artery. The treatment options then include irradiation, "palliative peeling" of tumor from the artery, and carotid resection with ligation or in-line grafting. Twelve patients with invasion of the carotid artery by cancer had en bloc resection of the artery and tumor.

Adrenergic response to nicardipine in the management of postoperative hypertension.

Nicardipine, a new dihydropyridine calcium channel blocking agent, has been shown to be effective in the management of hypertension. The adrenergic response to intravenous nicardipine as measured by changes in plasma catecholamine concentrations in seven patients undergoing treatment of postoperative hypertension is reported. Postoperative hypertension was defined as a systolic blood pressure (SBP) greater than 140 mm Hg.

Ruptured abdominal aortic aneurysm and horseshoe kidney.

We have described three patients surviving resection of a ruptured abdominal aortic aneurysm in the presence of horseshoe kidney. If division of the renal isthmus is required to gain rapid control of the ruptured abdominal aortic aneurysm, it is not necessarily associated with increased morbidity or mortality. The arterial supply to the horseshoe kidney may complicate arterial reconstruction, but with flexible use of modern vascular surgical techniques, preservation of renal tissue is feasible.

Renal artery aneurysm: selective treatment for hypertension and prevention of rupture.

Thirty-nine patients with renal artery aneurysm (RAA) were seen over a period of 15 years. Among 20 women and 19 men, 31 were found to have solitary aneurysms, and eight had multiple RAA. Thirty-three patients had diastolic hypertension; nine of them proved to be of renovascular origin.

Penetrating popliteal artery injuries in children.

Two children, aged 8 and 12, were seen recently at the Vanderbilt University Medical Center and Metropolitan Nashville General Hospital with gunshot injury to the popliteal artery. Both patients presented with late complications following missed penetrating injury to the popliteal artery. At presentation, distal pulses were palpable despite significant proximal arterial injury.

Phlegmasia cerulea dolens: therapeutic considerations.

Phlegmasia cerulea dolens (PCD) is a rare venous disorder that continues to be a major therapeutic challenge. We reviewed 16 cases of PCD treated during the past 15 years; 11 of the patients were male, and the average age of all the patients was 59 years. Malignant disease was the most common underlying condition (seven patients).

Familial fibromuscular dysplasia of the mesenteric arteries.

We have reported the case of a critically ill 17-year-old girl who had an evolving gastrointestinal infarction when she came to our institution 11 months before she died. After surgical revascularization, biopsy of the superior mesenteric artery showed FMD. We interviewed and examined all close consanguineous relatives and found abdominal bruits in the patient's younger sister and mother.

Failed percutaneous transluminal renal angioplasty: experience with lesions requiring operative intervention.

Percutaneous transluminal angioplasty (PTA) has received widespread publicity as a safe, simple, and successful alternative to operation for the management of renal artery stenoses and renovascular hypertension (RVH). Although, in our institution, the primary management of RVH remains operative revascularization, with more than 750 such procedures having been done, we have had the opportunity to manage a spectrum of PTA failures in nine patients during the last 5 years. These include (1) acute dissection of atherosclerotic lesions and occlusion of the distal renal artery requiring emergency operation; (2) unilateral perforation and bilateral thrombosis of fibrodysplastic branch renal artery lesions requiring staged ex vivo reconstruction; (3) cholesterol embolization and recurrence to total occlusion of orificial atherosclerotic lesions with loss of excretory renal function; (4) chronic dissection from repeated "temporarily successful" PTAs of medial fibrodysplastic lesions; and (5) rapid recurrence and acceleration of hypertension in a 17-year-old girl with congenital renal artery stenoses.

Ex vivo renal artery reconstructions: indications and techniques.

Ex vivo renal artery surgery has been reported by several investigators and has extended the role of revascularization in the treatment of lesions previously managed by nephrectomy alone. Several techniques are available for use, and selection of the most appropriate method can be tailored to the specific anatomy being managed. Our total experience included 27 kidneys that have been managed by ex vivo renal artery reconstruction.

Mycotic embolism and embolomycotic aneurysms. Neglected lessons of the past.

During the past decade, nine patients with bacterial endocarditis have required management of mycotic emboli and/or aneurysms in this center. In these patients, 25 separate mycotic emboli or aneurysms were identified. Among these were four visceral, 11 lower extremity, one aortic, one hypogastric, and eight cerebral lesions.
