Screening Mammography for Males With Elevated Breast Cancer Risk, Mutation Carriers, and Gynecomastia.

INTRODUCTION: The recommendations for annual mammography for male carriers with gynecomastia are controversial. This study investigated the potential link between gynecomastia and breast cancer in male carriers. PATIENTS AND METHODS: The database of a tertiary medical center was retrospectively searched for all male patients who underwent at least 1 digital mammography study from 2016 to 2023. Known carriers of a pathogenic variant in a high-risk breast-cancer gene were identified. Patients were stratified by carrier status, diagnosis of breast cancer, and diagnosis of gynecomastia. Data on demographics, hormone profile, and pathology results were compared. RESULTS: The cohort included 446 men of whom 82 were known carriers. Gynecomastia was diagnosed by mammography in 251 patients: 239/364 noncarriers (66%) and 12/82 carriers (15%) (P < .0001). Breast cancer was found in 21/364 noncarriers (6%) and 6/82 carriers (7%) (P < .6), and in 10/251 patients with gynecomastia (4%) and 17/193 (9%) without gynecomastia (P < .05). Among patients without gynecomastia, the number of breast cancer cases was similar in carriers and noncarriers (P = .3). Among patients with gynecomastia, the rate of breast cancer was higher in carriers (P < .08). On logistic regression analysis, the effect of gynecomastia on carriers was significant (P = .02). The odds ratio for a breast cancer diagnosis was 5.8 in the presence of gynecomastia (95% CI, 1.1-31, P < .04) and 0.52 in the absence of gynecomastia (95% CI, 0.2-1.7, P < .3). CONCLUSION: Gynecomastia may be associated with an increased risk of breast cancer in carriers. Larger studies are needed to determine whether and when to screen male carriers.

Pathogens Causing Pediatric Community Acquired Urinary Tract Infections and Their Increasing Antimicrobial Resistance: A Nationwide Study.

Urinary tract infections (UTIs) in childhood are common and are associated with considerable acute morbidity and long-term complications. The need for updated data to optimize empiric antibiotic therapy is crucial. We aimed to investigate the pathogens causing pediatric community acquired UTIs, their correlation with demographic characteristics, and trends in their antimicrobial resistance. This nationwide cross-sectional study included all 53,203 children (<18 years) diagnosed with UTI in community outpatient clinics in the following selected years: 2007, 2011, 2015, 2019 and 2021. Escherichia coli (E. coli) (82.1%) was the most common uropathogen, followed by Enterobacter, Klebsiella, Proteus, Pseudomonas, and Enterococcus species. The bacterial distribution displayed statistically significant (p < 0.0001) gender- and sector-specific patterns with a higher relative prevalence of non-E. coli UTI in Jewish and males. The rate of extended-spectrum beta-lactamase-positive E. coli increased substantially and significantly (p < 0.001) from only 6.1% in 2007 to 25.4% in 2021. Most non-E. coli uropathogens exhibited resistance to commonly used empiric antibiotics for UTIs in children. These findings are significant in guiding optimal empiric antibiotic treatment for pediatric community acquired UTIs. The resistance of uropathogens to antimicrobials is region- and time-dependent. Therefore, the periodic and local assessment of antibiotic resistance trends is essential to update guidelines and provide the most appropriate antibacterial therapy for children with UTIs.

Disparities in Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitor Prescription and Dispensing in the Israeli Population-A Retrospective Cohort Study.

OBJECTIVE: To describe disparities in prescribing and dispensing sodium-glucose cotransporter 2 inhibitors (SGLT2i) in Israel. RESEARCH DESIGN AND METHODS: This was a population-based retrospective cohort study of adults with type 2 diabetes eligible for SGLT2i treatment from 2017 to 2023. The primary outcome was the time between initial eligibility and the first prescription of SGLT2i. RESULTS: Among 32,742 eligible patients, only 53% were prescribed SGLT2i. Multivariable analyses, adjusting for death as a competing risk, revealed delays in prescription were associated with older age, Arab or Bedouin ethnicity, neoplasms, acute kidney failure, falls, previous hospitalization, urinary tract infections, and dementia. Factors associated with shorter time intervals to prescription were sex (men), medium/high socioeconomic status, and residing in an intermediate or central area of Israel. CONCLUSIONS: Disparities in drug prescription exist, even in a country with universal health coverage. Addressing these disparities requires improvements in health care systems, education, and alert systems to overcome barriers to evidence-based interventions.

Long-Term outcomes of pediatric dacryocystorhinostomy in a single medical center- a retrospective study.

PURPOSE: To examine the long-term success rate of pediatric endoscopic DCR surgery via telephone questionnaires, as determined by patients and their parents. METHODS: This is a retrospective cohort study of all patients who underwent DCR surgery at the Schneider Children's Medical Center of Israel between 2010 and 2020. We performed long-term follow-ups to assess the quality of life, surgical complications, and satisfaction with surgical outcomes. RESULTS: Our study includes seventy-nine patients with a total of 108 eyes. The mean age at the time of DCR was 7.05 years (Std = 4, min = 0.3, max = 17.7) Mean follow-up time was 5.7 years (Std =2.5, min = 1.4, max = 11.1). Tubes were inserted for a mean of 129 days (Std = 101). Fifty-seven patients (72%) declared they had no complications after surgery, three patients (4%) reported pain after surgery, and 14 patients (17.7%) reported tube extrusion, which occurred 7-21 days after surgery. Forty-four patients (56%) reported no recurrence of symptoms, 29 (37%) complained of mild epiphora, and 18 (23%) reported some ocular discharge. Sixty-eight patients (86%) stated that they did not undergo additional surgery, while the remaining 11 (14%) reported undergoing a revision operation for symptom control. Satisfaction rate (1-7) mean score reported was 6.15 (Std = 1.6). Sixty-two (78%) reported improved quality of life, while 17 (22%) reported no improvement. Our questionnaire results have been compared with the TEARS scores with similar findings. CONCLUSION: Regardless of its etiology, endoscopic DCR surgery in the pediatric population is safe and efficient, with a high long-term patient satisfaction rate, as reported via a telephone questionnaire.

Anatomic Location Influences Duration of Local Lidocaine Anesthesia in Dermatologic Surgery.

BACKGROUND: Although the onset and duration of local anesthetics are well-defined, how the anatomic site influences the duration of local anesthetics has not been well characterized in dermatology. OBJECTIVE: To define the duration of local anesthesia by anatomic site. MATERIALS AND METHODS: This was a prospective study. Adult healthy volunteers and patients undergoing Mohs micrographic surgery were invited to participate. The nose and the shin were chosen to represent highly and poorly vascularized anatomic sites, respectively. A total of 0.5 mL of buffered 1% lidocaine hydrochloride with 1:100,000 epinephrine was injected subcutaneously into each anatomic site of each participant. A pinprick test was used to assess adequate anesthesia until return of baseline sensation or visit completion. RESULTS: This study enrolled 25 participants. Time to return of sensation was significantly shorter on the nose compared with the shin ( p < .0001). On the nose, there was an association between male sex and shorter time to return of sensation. CONCLUSION: Time to return of sensation is significantly shorter on the nasal ala compared with the shin, suggesting that patients may regain sensation sooner on highly vascularized sites. Defining the duration of local anesthetics based on anatomic regions is important for treatment planning in dermatologic procedures.

Clinical Outcomes of Hospitalized Patients with SARS-CoV-2 Omicron Variant vs. Influenza A During Influenza Season 2021 to 2022: A Retrospective Observational Study.

BACKGROUND: Influenza and coronavirus disease 2019 (COVID-19) are respiratory diseases with similar modes of transmission. In December 2021, influenza re-emerged after it had been undetected since March 2020 and the Omicron variant replaced the Delta variant. Data directly comparing the two diseases are scarce. OBJECTIVES: To compare the outcomes of patients with both the Omicron variant and influenza during 2021-2022. METHODS: We performed a retrospective study conducted in Beilinson hospital, Israel, from December 2021 to January 2022. We included all hospitalized patients with either laboratory-confirmed COVID-19 or influenza. The primary outcome was 30-day mortality. RESULTS: We identified 167 patients diagnosed with Omicron and 221 diagnosed with Influenza A. The median age was 71 years for Omicron and 65 years for influenza. Patients with Omicron had a significantly higher Charlson Comorbidity Index score (4 vs. 3, P < 0.001). Patients with Omicron developed more respiratory failure that needed mechanical ventilation (7% vs. 2%, P = 0.05) and vasopressors (14% vs. 2%, P < 0.001) than patients with influenza. In a multivariate model, 30-day mortality was lower in patients diagnosed with influenza than in patients diagnosed with Omicron (19/221 [9%] vs. 44/167 [26%], hazard ratio 0.45, 95% confidence interval 0.25-0.81). CONCLUSIONS: Patients diagnosed with Omicron had higher mortality than patients diagnosed with seasonal influenza. This finding could be due to differences in co-morbidities, the virus pathogenicity, and host responses to infection.

Extracorporeal photopheresis induces NETosis in neutrophils derived from patients with chronic graft-vs-host disease.

INTRODUCTION: Extracorporeal photopheresis (ECP) is considered an effective treatment for patients with chronic graft vs host disease (cGVHD) and demonstrates efficacy in ameliorating GVHD. The mechanism by which ECP acts against cGVHD is not fully understood. Preliminary observations have hinted at the potential involvement of neutrophil extracellular traps (NETs) formation in the pathogenesis of cGVHD. We aimed to assess the influence of ECP on the formation of NETs in patients with cGVHD as a potential mechanism in this setting. METHODS: Patients treated with ECP for cGVHD at the Rabin Medical Center were included in this study. Blood samples were obtained at three different time points: before starting an ECP cycle, at the end of the first day of treatment, and 24 h following the initiation of the ECP treatment cycle. Neutrophils were harvested from all blood samples. NET formation was assessed by measurement of NET-bound specific neutrophil elastase activity and by immunofluorescence staining. RESULTS: Six patients (two females and four males) with cGVHD were included in the study. We observed a significant increase in NET formation among all six patients following ECP. Net-bound specific neutrophil elastase activity was elevated from a median value of 2.23 mU/mL (interquartile range [IQR] 2.06-2.47 mU/mL) at baseline to a median value of 13.06 mU/mL (IQR 10.27-15.97 mU/mL) immediately after the treatment and to a peak median value of 14.73 mU/mL (IQR 9.6-22.38 mU/mL) 24 h following the initiation of the ECP cycle. A qualitative assessment of NET formation using immunofluorescence staining has demonstrated markedly increased expression of citrullinated histone H3, a marker of NET formation, following ECP treatment. CONCLUSIONS: Our preliminary data indicate that ECP induces NET formation among patients with cGVHD. The contribution of increased NET formation to the therapeutic effect of cGVHD should be further investigated.

Rituximab versus obinutuzumab-based first-line chemoimmunotherapy for follicular lymphoma-a real-world multicenter retrospective cohort study.

The GALLIUM study showed a progression-free survival advantage of 7% in favor of obinutuzumab vs. rituximab-based immunochemotherapies as first-line therapy in follicular lymphoma (FL) patients. Yet, the toxicity appears to be increased with obinutuzumab-based therapy. This is a multicenter retrospective-cohort study including adult FL patients comparing the toxicity of first-line rituximab vs. obinutuzumab-based chemo-immunotherapies (R and O groups, respectively). We compared the best standard-of-care therapy used per time period, before and after obinutuzumab approval. The primary outcome was any infection during induction and 6 months post-induction. Secondary outcomes included rates of febrile neutropenia, severe and fatal infections, other adverse events, and all-cause mortality. Outcomes were compared between groups. A total of 156 patients were included in the analysis, 78 patients per group. Most patients received bendamustine (59%) or CHOP (31.4%) as adjacent chemotherapy. Half of the patients received growth-factor prophylaxis. Overall, 69 patients (44.2%) experienced infections, and a total of 106 infectious episodes were recorded. Patients in the R and O groups had similar rates of any infection (44.8% and 43.5%, p = 1), severe infections (43.3% vs. 47.8%, p = 0.844), febrile neutropenia (15% vs. 19.6%, p = 0.606), and treatment discontinuation, as well as similar types of infections. No covariate was associated with infection in multivariable analysis. No statistically significant difference was evident in adverse events of grades 3-5 (76.9% vs. 82%, p = 0.427). To conclude, in this largest real-life study of first-line treated FL patients comparing R- to O-based therapy, we did not observe any difference in toxicity during the induction and 6 months post-induction period.

The prevalence of masked hypertension in patients with lone atrial fibrillation: a cross sectional analytical study.

Atrial fibrillation (AF) is prevalent in individuals with essential hypertension (HTN). Masked hypertension occurs in up to 15% of the general population and is associated with adverse clinical outcome. The aim of the current study was to evaluate the prevalence of masked hypertension in apparently normotensive individuals with lone AF. A cross sectional analytical study performed at the Rabin Medical Center included all patients > 18 years who visited the emergency department (ED) in the years 2018-2021 with idiopathic AF, had normal blood pressure (BP) values during their ED visit and did not have a history of hypertension or current use of anti-hypertensives. Ambulatory blood pressure monitoring (ABPM) was performed in all eligible patients within 30 days from ED visit. Data collected included information from the ED visit and data extracted from the monitoring device. A total of 1258 patients were screened for eligibility, of which 40 were included in the analysis. The average age was 53.4 ± 16 years, 28 patients (70%) were males. Overall, 18 individuals (46%) had abnormal BP values according to the 2017 ACC/AHA guidelines for the diagnosis of hypertension. Of these, 12 had abnormal 24-h BP average (≥ 125/75 mmHg), one had isolated daytime abnormal average (≥ 130/80 mmHg) and 11 had isolated night time abnormal average (≥ 110/65 mmHg). Masked hypertension is prevalent in patients with lone AF without a diagnosis of HTN and performing ABPM in such individuals should be strongly considered.

Arterial and Venous Thromboembolism in ALK-Rearrangement-Positive Non-small Cell Lung Cancer: A Population-Based Cohort Study.

INTRODUCTION: There is scarce data regarding the incidence of venous thromboembolism (VTE) and arterial thromboembolism (ATE) in the molecular subtypes of non-small cell lung cancer (NSCLC). We aimed to investigate the association between Anaplastic Lymphoma Kinase (ALK)-positive NSCLC and thromboembolic events. METHODS: A retrospective population-based cohort study of the Clalit Health Services database, included patients with NSCLC diagnosed between 2012 and 2019. Patients exposed to ALK-tyrosine-kinase inhibitors (TKIs) were defined as ALK-positive. The outcome was VTE (at any site) or ATE (stroke or myocardial infarction) 6 months prior to the diagnosis of cancer, until 5 years post-diagnosis. The cumulative incidence of VTE and ATE and hazard-ratios (HR) with 95% CIs were calculated (at 6- 12- 24 and 60-months), using death as a competing risk. Cox proportional hazards multivariate regression was performed, with the Fine and Gray correction for competing risks. RESULTS: The study included 4762 patients, of which 155 (3.2%) were ALK-positive. The overall 5-year VTE incidence was 15.7% (95% CI, 14.7-16.6%). ALK-positive patients had a higher VTE risk compared to ALK-negative patients (HR 1.87 [95% CI, 1.31-2.68]) and a 12-month VTE incidence of 17.7% (13.9-22.7%) compared to 9.9% (9.1-10.9%) in ALK-negative patients. The overall 5-year ATE incidence was 7.6% [6.8-8.6%]. ALK positivity was not associated with ATE incidence (HR 1.24 [0.62-2.47]). CONCLUSIONS: In this study, we observed a higher VTE risk, but not ATE risk, in patients with ALK-rearranged NSCLC relative to those without ALK rearrangement. Prospective studies are warranted to evaluate thromboprophylaxis in ALK-positive NSCLC.

The short and long-term characteristics and outcomes of patients with grade 1 myocardial uptake on cardiac scintigraphy.

AIMS: This study aimed to characterize the final diagnosis and prognosis of patients with grade 1 myocardial scintigraphy uptake, which is an unequivocal result for the diagnosis of transthyretin cardiac amyloidosis (ATTR-CA) requiring further invasive investigation with tissue biopsy. METHODS AND RESULTS: We retrospectively compared the clinical and imaging parameters of patients suspected for ATTR-CA (based on clinical and echocardiographic parameters) with grade 1 vs. grades 2/3 technetium pyrophosphate uptake on cardiac scintigraphy. Prospectively, grade 1 patients underwent re-evaluation for ATTR-CA at long term. Of the 132 ATTR-CA suspected patients, 89 (67%) were diagnosed as grade 1 and 43 (33%) as grades 2/3 uptake. Grade 1 vs. grades 2/3 patients were younger and female predominant with lower biomarker levels and left ventricular mass. Based on available imaging and pathology findings, only 6 out of the 89 patients with grade 1 uptake (7%) were finally diagnosed with light-chain cardiac amyloidosis, whereas no patient was diagnosed with ATTR-CA. At 2 [interquartile range (IQR) 0.75, 3.25] years of follow-up, the survival of patients with grade 1 vs. grades 2/3 uptake was significantly better [hazard ratio 0.271 (95% confidence interval 0.130 to 0.563, P = 0.0005)]. Prospectively, 30 patients with grade 1 uptake were re-evaluated at a median follow-up of 3.2 (IQR 2.2, 3.9) years. Their New York Heart Association class, biomarker levels, and echocardiography findings remained stable. No patient (0/25) demonstrated grades 2/3 uptake at repeated long-term scintigraphy. CONCLUSIONS: Patients with suspected ATTR-CA and a grade 1 scintigraphy uptake demonstrate a stable clinical, laboratory, imaging, and scintigraphy phenotype along with a benign survival profile at long-term follow-up. Larger studies should define the optimal evaluation strategy in this population.

A Longitudinal Assessment of the Natural Change in Haemoglobin, Haematocrit, and Mean Corpuscular Volume with Age.

INTRODUCTION: We aimed to assess the natural annual trends in the levels of haemoglobin, haematocrit, and mean corpuscular volume (MCV) in a population of adults, together with the influence of different clinical parameters on these trends. METHODS: A retrospective analysis was carried out on data from a large cohort of subjects attending a screening centre in Israel. For each subject, the yearly average change of haemoglobin, haematocrit, and MCV was calculated. Statistical analysis was performed for the whole cohort and for different subgroups. RESULTS: The study included 3,551 subjects. The average annual rates of decline were found to be -0.0550 g/dL (95% confidence interval [CI] -0.0590 g/dL to -0.0503 g/dL) and -0.097% (95% CI -0.112% to -0.083%) for haemoglobin and haematocrit, respectively. An average annual increase in the MCV level by 0.184 fL (95% CI 0.168 fL-0.200 fL) was found. Among men, the rate of decline in haemoglobin was found to be twice as high compared with women -0.06 g/dL versus -0.03 g/dL, respectively (p = 0.0063). In a multivariate analysis, gender remained the only parameter significantly associated with the annual decline of haemoglobin (p = 0.0001). CONCLUSION: An annual average decrease in the levels of haemoglobin and haematocrit together with an annual increase in MCV was found. These changes were more prominent in men.

Pulmonary function tests for evaluating the severity of Duchenne muscular dystrophy disease.

AIM: In Duchenne muscular dystrophy (DMD), lung disease contributes significantly to morbidity and mortality. This study aimed to assess the usefulness of various pulmonary function tests in evaluating DMD severity. METHODS: This retrospective study analysed lung function tests of patients with DMD-treated in the multidisciplinary respiratory neuromuscular clinic at Schneiders' Children Medical Center of Israel. Data were analysed according to age, ambulatory status and glucocorticoid treatment. RESULTS: Among 90 patients with DMD, 40/63 (63.5%) ambulatory patients and 22/27 (81.5%) nonambulatory patients successfully performed spirometry. Significant annual declines were demonstrated among nonambulatory patients, in percentile predicted forced vital capacity (3.8%) and in total lung capacity (5.5%) per year. The decline correlated with age and loss of ambulation but not with steroid treatment. Peak cough flow values were randomly distributed and did not correlate with age, ambulation or treatment. In nonambulatory patients, transcutaneous carbon dioxide measurement correlated significantly with age (r = 0.55, p = 0.02). CONCLUSION: Forced vital capacity, total lung capacity and transcutaneous carbon dioxide correlated with the clinical severity of disease in children with DMD. These measures may be useful in follow-up and clinical trials. A comparable correlation was not found for peak cough flow.

Suspected Non-ST-elevation acute coronary syndrome meeting rapid rule-out criteria: resource utilization, diagnostic yield, and clinical outcomes of hospital admission.

AIMS: Many patients with suspected non-ST-elevation (NSTE) acute coronary syndromes (ACS) are admitted, even those with initial high-sensitivity cardiac troponins (hs-cTn) values who meet rapid rule-out criteria for myocardial infarction (MI). We examined the clinical outcomes, resource utilization, and diagnostic yield of suspected NSTE-ACS patients, who presented with hs-cTnT values meeting these criteria but were nevertheless hospitalized. METHODS AND RESULTS: Applying the 2020 European Society of Cardiology (ESC) rapid rule-out MI criteria, we identified consecutive patients with an initial value of hs-cTnT <5 ng/L or an initial value of ≥5 ng/L but <14 ng/L (99th percentile) and a small increment in a subsequent test, who were nevertheless admitted. The majority (85.4%) of patients presented to the emergency department (ED) with suspected NSTE-ACS had an initial hs-cTnT <99th percentile. We examined 3775 admitted patients out of 11 477 patients who were triaged and met MI rule-out criteria. Only 0.32% (12 patients) of admitted patients experienced index MI or overall death within 30 days. Resource utilization in terms of ED stay, hospital stay, noninvasive and invasive tests was substantial, yet revascularization was uncommon (2.5%). Multivariate adjustment for age, gender, and baseline cardiovascular risk factors demonstrates similar survival of admitted vs. discharged patients (P = 0.88). Initial hs-cTnT even below the 99th percentile provided a prognostic stratification for long term mortality. CONCLUSION: Our findings support a policy of ED discharge of suspected NSTE-ACS patients meeting rapid MI rule-out criteria and subsequent ambulatory evaluation, sparing resource-consuming admissions. In-hospital and ensuing prognosis were better with lower initial hs-cTnT values.

Preceding Clinical Events in High-risk, Postoperative, Pediatric Cardiac Patients-A Novel Association With Bacteremia.

Objective: Blood stream infections (BSIs) are well described in pediatric cardiac intensive care units (PCICU). We noted that postoperative high-risk patients may develop BSI after a preceding clinical event (PCE). The study aim was to investigate whether high-risk patients who developed bacteremia experienced more PCEs than a similar group of high-risk patients. Design: Retrospective case-control study. Setting: Referral pediatric center. Patients: We enrolled patients who developed bacteremia from March 2010 to November 2019, after undergoing open-heart surgery at a pediatric center. The control group was comprised of case-matched patients with immediate consecutive same surgery. Interventions: None. Measurements: We recorded operative data, common risk factors, postoperative indicators of organ dysfunction, mortality, and PCEs 72 to 24 h before bacteremia emerged. Main results: A total of 200 patients were included (100 with bacteremia and 100 controls). Key demographic and operative parameters were matched. Bacteremia emerged on average on postoperative day 12.8. Skin-associated Gram-positive bacteria were cultured in 10% and Gram-negative bacteria in 84% of the patients. Average central-venous lines (CVL) duration was 9.5 ± 8.4 days. Postoperatively (72 h), indicators of organ dysfunction were significantly worse in patients with bacteremia, with a higher rate of postoperative complications during PCICU length-of-stay (LOS). In the bacteremia group, 72 to 24 h prior to the development of bacteremia, 92 (92%) PCEs were recorded, as compared to 21 (21%) in controls during their entire LOS (odds ratio [OR] 43.3, confidence interval [CI] 18.2-103.1, P < .0001). Conclusions: We propose a 3-hit model demonstrating that high-risk patients undergoing open-heart surgery have significantly higher risk for bacteremia after a PCE.

Bedside Durable Tunneled Femoral Central Venous Catheter is Feasible and Safe in High-Risk Infants in the Pediatric Cardiac Intensive Care Unit.

OBJECTIVE: Ultrasound (US)-guided durable tunneled femoral central venous catheters (TF-CVCs) are a safe central venous access option in infants and neonates. Studies have shown, however, that femoral central venous access has the potential for high central line-associated bloodstream infection (CLABSI) rates with a significant increase in risk for line-related thrombosis. Our aims were to describe the bedside insertion technique and evaluate the safety and complication rates of TF-CVCs in high-risk, young, pediatric cardiac intensive-care unit (PCICU) population. DESIGN: A retrospective observational cohort study. SETTING: University affiliated, tertiary-care hospital, PCICU. PATIENTS: All PCICU patients that underwent bedside TF-CVC insertion were enrolled. Data was collected from the electronic medical record system. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During April 2016 to October 2021, 103 TF-CVC lines were inserted into 94 pediatric cardiac critical care patients, at the bedside. Patients' characteristics were median (IQR) age of 47.5 days (22.6, 120.5), weight 3.3 kg (2.9, 4.3), 33% prevalence of genetic anomalies, need for ECMO support in 20.4%, and STAT category 4-5 in 53.4%. All procedures were performed by intensivists. There were no immediate procedure-related complications. TF-CVCs were inserted on average on post-operative day (POD) 14, median line indwell duration was 25 days (16.3, 42.3) and total TF-CVC dwell duration for the entire cohort of 3442.7 days. During the study period eight CLABSI events were recorded (2.3/1000 line-days). Line obstruction rate was 1.16/1000 line-days and six lines were dislodged in the intermediate-care unit. There was no symptomatic line-related thrombosis. CONCLUSIONS: We show that US-guided durable tunneled femoral central venous catheter (TF-CVC) insertion by an intensivist at the bedside is a technically feasible and safe prolonged central venous access option in critically ill, high-risk infants and neonates in the PCICU.

Re-Admission of COVID-19 Patients Hospitalized with Omicron Variant-A Retrospective Cohort Study.

In accordance with previous publications, re-admission rates following hospitalization of patients with COVID-19 is 10%. The aim of the current study was to describe the rates and risk factors of hospital re-admissions two months following discharge from hospitalization during the fifth wave due to the dominant Omicron variant. A retrospective cohort study was performed in Rabin Medical Center, Israel, from November 2021 to February 2022. The primary outcome was re-admissions with any diagnosis; the secondary outcome was mortality within two months of discharge. Overall, 660 patients were hospitalized with a diagnosis of COVID-19. Of the 528 patients discharged from a primary hospitalization, 150 (28%) were re-admitted. A total of 164 patients (25%) died throughout the follow-up period. A multi-variable analysis determined that elevated creatinine was associated with a higher risk of re-admissions. Rates of re-admissions after discharge during the Omicron wave were considerably higher compared to previous waves. A discharge plan for surveillance and treatment following hospitalization is of great importance in the management of pandemics.

Infectious complications and long-term outcomes in patients with diffuse large B-Cell lymphoma and diabetes mellitus.

Febrile neutropenia (FN) is a major complication in patients with diffuse large B-Cell lymphoma (DLBCL). Diabetes mellitus (DM) has deleterious effects on the immune system resulting in an increased risk of infections. We evaluated patients with DLBCL who started frontline treatment with R-CHOP, and compared outcomes according to presence of DM comorbidity. Between 2013 and 2018, 218 patients with DLBCL were included. 46 patients (21%) had DM. Rate of admissions for FN was higher for patients with DM (0.7 vs. 0.46 admissions/patient, p = .016), also after age and gender-matched subgroup analysis (p = .004). Improved glycemic control during FN hospitalizations was associated with shorter hospitalizations. Metformin was associated with improved median overall survival in diabetic patients (89 vs. 64 months, p = .018). In conclusion, Patients with DLBCL and DM had higher rates of FN hospitalizations. Improved glycemic control during FN hospitalization was associated with shorter length of stay.

Effect of steroid treatment on the diagnostic yield of baseline 18f-fluorodeoxyglucose positron emission tomography in aggressive B cell lymphoma.

Aggressive B cell lymphoma often requires prompt steroid treatment, even before baseline 18f-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) and definitive treatment, to alleviate symptoms or prevent organ damage. Since lymphoma is a steroid-sensitive malignancy, there are concerns that steroids might affect the results of FDG PET/CT and decrease its diagnostic yield. The aim of the current study was to evaluate the effect of steroids administered before baseline PET/CT on the maximum standardized uptake value (SUVmax) and additional PET/CT parameters. Retrospective review of the database in a tertiary medical center yielded 178 patients newly diagnosed with aggressive B cell lymphoma between January 2017 and May 2020 who had an available baseline FDG PET/CT scan. The cohort was divided into patients who received steroids before PET/CT (n = 47) and those who did not (n = 131), and the groups were compared for SUVmax and additional PET/CT parameters. The steroid-treated group had a higher disease stage and lactate dehydrogenase level compared to the steroid-naïve group, with a trend toward a higher international prognostic index. There was no significant between-group difference in SUVmax (P = 0.61). This finding remained consistent across steroid treatment durations and dosage regimens. Further evaluation revealed a significantly larger mean tumor volume and a trend toward a higher tumor metabolic burden in the steroid-treated group, yet no between-group difference in SUV mean or other PET/CT parameters. In this retrospective analysis of patients with aggressive B cell lymphoma, steroid prophase prior to baseline PET/CT did not decrease the diagnostic yield of the scan. However, further studies are required to fully appreciate the impact of steroids on PET CT parameters.
