Impact of rapid blood culture identification PCR panel on optimal antibiotic use in methicillin-susceptible bacteremia.

Unlabelled: Rapid identification of methicillin-susceptible (MSSA) bacteremia may optimize antibiotic use and clinical outcomes. The study objective was to assess the impact of the BioFire® blood culture identification (BCID) polymerase chain reaction (PCR) panel on antibiotic use and clinical outcomes in patients with MSSA bacteremia. This was a retrospective chart review of adult inpatients with MSSA bacteremia during the pre-PCR (June 2018-December 2019) and post-PCR (June 2020-December 2021) implementation periods.

Diagnosis of GATA2 Deficiency in a Young Woman with Hemophagocytic Lymphohistiocytosis Triggered by Acute Systemic Cytomegalovirus Infection.

BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by an intense immunologic response that results in multiorgan dysfunction. It typically manifests as a result of a familial genetic immunodeficiency disorder or secondary to a trigger such as an infection, malignancy, or autoimmune disease. The major factors involved in the development of the disease are an individual's genetic propensity to develop HLH, such as rare associated mutations, or inflammatory processes that trigger the immune system to go haywire.

Analysis of the Effect of the Size and Grade of Soft Tissue Sarcoma on Rates of Unplanned Resection, Metastatic Disease, Mortality, and Morbid Re-Resection Over 20 Years.

Soft tissue sarcomas are rare malignancies that are often presumed to be benign and are resected without the typical preoperative workup, such as imaging or biopsy. These unplanned resections occur in approximately 30% of all cases and frequently require further morbid treatments, resulting in worse oncologic outcomes. A retrospective review was performed of all patients who presented to a tertiary sarcoma center with a diagnosis of sarcoma between 1996 and 2017.

'What I Wish My Surgeon Knew': A Novel Approach to Promote Empathic Curiosity in Surgery.

Objective: Physician empathy is associated with a variety of superior patient and physician outcomes. Teaching physicians to practice empathic curiosity is challenging however, and relatively few efficient and effective methods have been proposed toward this end. The goal of this study was to evaluate the impact and feasibility of a novel approach to foster empathic curiosity during surgical training.

Predominance of Spinal Metastases Involving the Posterior Vertebral Body.

Background: Spinal metastases pose significant morbidity. For many histologies, the spine is a frequent site for bone metastases. This predilection is not fully understood, and there are conflicting reports regarding the distribution within the vertebral body itself.

Using value of information methods to determine the optimal sample size for effectiveness trials of alcohol interventions for HIV-infected patients in East Africa.

Background: Unhealthy alcohol consumption exacerbates the HIV epidemic in East Africa. Potential benefits of new trials that test the effectiveness of alcohol interventions could not be evaluated by traditional sampling methods. Given the competition for health care resources in East Africa, this study aims to determine the optimal sample size given the opportunity cost of potentially re-allocating trial funds towards cost-effective alcohol treatments.

Economic evaluation of mobile phone text message interventions to improve adherence to HIV therapy in Kenya.

Background: A surge in mobile phone availability has fueled low cost short messaging service (SMS) adherence interventions. Multiple systematic reviews have concluded that some SMS-based interventions are effective at improving antiretroviral therapy (ART) adherence, and they are hypothesized to improve retention in care. The objective of this study was to evaluate the cost-effectiveness of SMS-based adherence interventions and explore the added value of retention benefits.

Peripheral Sensory Neurons Expressing Melanopsin Respond to Light.

The ability of light to cause pain is paradoxical. The retina detects light but is devoid of nociceptors while the trigeminal sensory ganglia (TG) contain nociceptors but not photoreceptors. Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) are thought to mediate light-induced pain but recent evidence raises the possibility of an alternative light responsive pathway independent of the retina and optic nerve.

Impact and Cost-Effectiveness of Hypothetical Strategies to Enhance Retention in Care within HIV Treatment Programs in East Africa.

Objectives: Attrition from care among HIV infected patients can lead to poor clinical outcomes. Our objective was to evaluate hypothetical interventions seeking to improve retention-in-care (RIC) for HIV-infected patients in East Africa, asking whether they could offer favorable value compared to earlier ART initiation.

Methods: We used a micro-simulation model to analyze two RIC focused strategies within an East African HIV treatment program--"risk reduction," defined as intervention(s) that decrease the risk of attrition from care; and "outreach," defined as interventions that find patients and relink them with care.

Targeting an alcohol intervention cost-effectively to persons living with HIV/AIDS in East Africa.

Background: In the current report, we ask if targeting a cognitive behavioral therapy (CBT)-based intervention aimed at reducing hazardous alcohol consumption to HIV-infected persons in East Africa would have a favorable value at costs that are feasible for scale-up.

Methods: Using a computer simulation to inform HIV prevention decisions in East Africa, we compared 4 different strategies for targeting a CBT intervention-(i) all HIV-infected persons attending clinic; (ii) only those patients in the pre-antiretroviral therapy (ART) stages of care; (iii) only those patients receiving ART; and (iv) only those patients with detectable viral loads (VLs) regardless of disease stage. We define targeting as screening for hazardous alcohol consumption (e.

Enhanced Tuberculosis Infection Treatment Outcomes after Implementation of QuantiFERON®-Gold Testing.

Background: Use of the tuberculin skin test (TST) for diagnosis of latent tuberculosis infection (LTBI) among individuals who received the Bacille Calmette-Guérin (BCG) vaccine is complicated by its potential cross-reaction with TST antigens which may cause false-positive results and lead to patient and physician reluctance to initiate LTBI treatment. QuantiFERON®-TB Gold (QFT-G) lacks this cross-reaction. We sought to study the impact of implementing QFT-G testing in 2006 on LTBI treatment initiation and completion at NYC chest clinics.

Persistent dilemmas in zoster eye disease.

Herpes zoster ophthalmicus (HZO) is a common, vision and potentially life-threatening disease caused by the reactivation of the varicella-zoster virus (VZV) in the distribution of the first division of cranial nerve V. Although the rate of herpes zoster increases with age, over half of the people with zoster in general, including HZO, are under age 60. In addition, over 90% of people with zoster are immunocompetent, even though the disease is more common and severe in immunocompromised patients.

Implementation and Operational Research: A Time-Motion Analysis of HIV Transmission Prevention Counseling and Antiretroviral Adherence Messages in Western Kenya.

Background: Shortages of health workers and large number of HIV-infected persons in Africa mean that time to provide antiretroviral therapy (ART) adherence and other messages to patients is limited.

Methods: Using time-motion methodology, we documented the intensity and nature of counseling delivered to patients. The study was conducted at a rural and an urban HIV clinic in western Kenya.

Evaluating the impact of prioritization of antiretroviral pre-exposure prophylaxis in New York.

Objective: To compare the value and effectiveness of different prioritization strategies of pre-exposure prophylaxis (PrEP) in New York City (NYC).

Design: Mathematical modelling utilized as clinical trial is not feasible.

Methods: Using a model accounting for both sexual and parenteral transmission of HIV, we compare different PrEP prioritization strategies (PPS) with two scenarios – no PrEP and PrEP for all susceptible at-risk individuals.

Cost-effectiveness of different strategies to monitor adults on antiretroviral treatment: a combined analysis of three mathematical models.

Background: WHO's 2013 revisions to its Consolidated Guidelines on antiretroviral drugs recommend routine viral load monitoring, rather than clinical or immunological monitoring, as the preferred monitoring approach on the basis of clinical evidence. However, HIV programmes in resource-limited settings require guidance on the most cost-effective use of resources in view of other competing priorities such as expansion of antiretroviral therapy coverage. We assessed the cost-effectiveness of alternative patient monitoring strategies.

Hepatitis C virus infection among HIV-positive men who have sex with men: protocol for a systematic review and meta-analysis.

Background: Outbreaks of hepatitis C virus (HCV) infection have been reported in HIV-positive men who have sex with men (MSM) in North America, Europe and Asia. Transmission is believed to be the result of exposure to blood during sexual contact. In those infected with HIV, acute HCV infection is more likely to become chronic, treatment for both HIV and HCV is more complicated and HCV disease progression may be accelerated.

How do different eligibility guidelines for antiretroviral therapy affect the cost-effectiveness of routine viral load testing in sub-Saharan Africa?

Background: Increased eligibility guidelines of antiretroviral therapy (ART) may lead to greater routine viral load monitoring. However, in resource-constrained settings, the additional resources required by greater routine viral load monitoring may impair ability to comply with expanded eligibility guidelines for ART.

Objective: We use a published validated computer simulation of the HIV epidemic in East African countries (expanded to include transmission as well as disease progression) to evaluate the cost-effectiveness of routine viral load monitoring.

Impact of interventions targeting unhealthy alcohol use in Kenya on HIV transmission and AIDS-related deaths.

Background: HIV remains a major cause of preventable morbidity and mortality in Kenya. The effects of behaviors that accompany unhealthy alcohol consumption are a pervasive risk factor for HIV transmission and progression. Our objective was to estimate the portion of HIV infections attributable to unhealthy alcohol use and to evaluate the impact of hypothetical interventions directed at unhealthy alcohol use on HIV infections and deaths.
