B-Lymphoblastic Lymphoma Isolated to the Testes: A Case Report and Review of Literature.

Isolated testicular involvement in pediatric lymphoma is rare and poses diagnostic challenges. In this study, the case of an isolated testicular B-lymphoblastic lymphoma in a 9-year-old boy is discussed with an emphasis on the difficulties in diagnosing and treating such an unusual presentation. This example illustrates the importance of considering lymphoblastic lymphoma in the differential diagnosis of an unidentified source of testicular enlargement.

Incidence and Transmission of SARS-CoV-2 in US Child Care Centers After COVID-19 Vaccines.

Importance: SARS-CoV-2 surveillance studies in US child care centers (CCCs) in the post-COVID-19 vaccine era are needed to provide information on incidence and transmission in this setting.

Objective: To characterize SARS-CoV-2 incidence and transmission in children attending CCCs (students) and their child care providers (CCPs) and household contacts.

Design, Setting, And Participants: This prospective surveillance cohort study was conducted from April 22, 2021, through March 31, 2022, and included 11 CCCs in 2 cities.

The impact of bedside wipes in multi-patient rooms: a prospective, crossover trial evaluating infections and survival.

Background: Multidrug-resistant organisms (MDROs) are prevalent on high-touch surfaces in multi-patient rooms.

Aim: To quantify the impact of hanging single-use cleaning/disinfecting wipes next to each bed. Pre-specified outcomes were: (1) hospital-acquired infections (HAIs), (2) cleaning frequency, (3) MDRO room contamination, (4) new MDRO acquisitions, and (5) mortality.

Outcomes of complete surgical repair versus palliative intervention in neonates with Tetralogy of Fallot.

Using the US National Inpatient Sample dataset (2010 to 2018), we compared outcomes of neonates with Tetralogy of Fallot who had early primary surgical repair (1726 neonate) and those who had staged palliative intervention with transcatheter (1702 neonate) or surgical palliative shunt (2661 neonate).

Expanding Surveillance Toward Sharing Data with the Community: Qualitative Insights from a Childcare Center Illness Surveillance Program.

Childcare attendance is a recognized independent risk factor for pediatric infectious diseases due to the pathogen-sharing behaviors of young children and the crowded environments of childcare programs. The Michigan Child Care Related Infections Surveillance Program (MCRISP) is a novel online illness surveillance network used by community childcare centers to track disease incidence. It has been used to warn local public health departments about emerging outbreaks.

A "resistance calculator": Simple stewardship intervention for refining empiric practices of antimicrobials in acute-care hospitals.

Objective: In the era of widespread resistance, there are 2 time points at which most empiric prescription errors occur among hospitalized adults: (1) upon admission (UA) when treating patients at risk of multidrug-resistant organisms (MDROs) and (2) during hospitalization, when treating patients at risk of extensively drug-resistant organisms (XDROs). These errors adversely influence patient outcomes and the hospital's ecology.

Design And Setting: Retrospective cohort study, Shamir Medical Center, Israel, 2016.

Using the MCRISP Network for Surveillance of Pediatric Exanthema in Child Care Centers.

Background: Systematic monitoring of exanthema is largely absent from public health surveillance despite emerging diseases and threats of bioterrorism. Michigan Child Care Related Infections Surveillance Program (MCRISP) is the first online program in child care centers to report pediatric exanthema.

Methods: MCRISP aggregated daily counts of children sick, absent, or reported ill by parents.

Targeting the Type II Secretion System: Development, Optimization, and Validation of a High-Throughput Screen for the Identification of Small Molecule Inhibitors.

Nosocomial pathogens that develop multidrug resistance present an increasing problem for healthcare facilities. Due to its rapid rise in antibiotic resistance, is one of the most concerning gram-negative species. typically infects immune compromised individuals resulting in a variety of outcomes, including pneumonia and bacteremia.

Glioblastoma cell line-derived spheres in serum‑containing medium versus serum-free medium: a comparison of cancer stem cell properties.

In addition to the primary culturing of cancer stem cells (CSCs) from tumor tissues, CSCs are found in established tumor cell lines. However, it is unclear how culture conditions affect CSC enrichment. Additionally, the differentiation potential of cell line-derived CSCs has not been well studied.

Randomized equivalence study evaluating the possibility of switching hemodialysis patients receiving subcutaneous human erythropoietin directly to intravenous darbepoetin alfa.

Background: Darbepoetin alfa is an erythropoiesis-stimulating agent (ESA) used either intravenously or subcutaneously with no dose penalty; however, the direct switch from subcutaneous recombinant human erythropoietin (rHuEPO) to intravenous darbepoetin has barely been studied.

Objective: To establish the equivalence of a direct switch from subcutaneous rHuEPO to intravenous darbepoetin versus an indirect switch from subcutaneous rHuEPO to intravenous darbepoetin after 2 months of subcutaneous darbepoetin in patients undergoing hemodialysis.

Methods: In this open, randomized, 6-month, prospective study, patients with end-stage kidney disease who were on hemodialysis were randomized into 2 groups: direct switch from subcutaneous rHuEPO to intravenous darbepoetin (group 1) and indirect switch from subcutaneous rHuEPO to intravenous darbepoetin after 2 months of subcutaneous darbepoetin (group 2).

[Adenosine deaminase is useful for the diagnosis of peritoneal tuberculosis in patients with end-stage renal failure].

Introduction: End-stage renal failure patients are particularly at risk for tuberculosis, especially for peritoneal tuberculosis. Microbiological diagnosis remains hazardous in many cases.

Case Report: We report on a case of peritoneal tuberculosis in an end-stage renal failure patient.

The "tract" of history in the treatment of lumbar degenerative disc disease.

In this paper past, present, and future treatments of degenerative disc disease (DDD) of the lumbar spine are outlined in a straight forward manner. This is done to review previous knowledge of the disease, define current treatment procedures, and discuss future perspectives. An analysis of a subject of this magnitude dictates that one describes as accurate a history as possible: an anatomical/historical "tract" with emphasis on all possible deviations.

Aortic and large artery compliance in end-stage renal failure.

Pulse wave velocity (PWV) was measured in the aorta, right leg and arm of 90 control subjects (CS) and 92 hemodialysis patients (HD) of the same age and mean arterial pressure (MAP). Blood chemistry, including blood lipids, and echographic dimensions of the aorta, were measured in all subjects. Presence of aortic calcification was evaluated by abdominal X-ray and echography.
