ABSTRACT
Background: Hyperuricemia is associated with several risk factors for mortality and severe coronavirus disease 2019 (COVID-19) manifestations.Objective: The objective of this research was to examine whether hyperuricemia is a risk factor for mortality and other adverse outcomes in patients hospitalized for COVID-19.Design: This is a retrospective review of patients hospitalized for COVID-19 between March 15 and November 30, 2020, with available uric acid (UA) levels.Results: Among 1566 patients who were hospitalized during the study period, 222 patients had an available UA level. The mean age ± standard deviation (SD) was 56.5 ± 19.5 years. The mean ± SD for UA (mg/dL) among the total cohort was 5.65 ± 2.18, and 21.2% of the total study population had hyperuricemia (UA > 7 mg/dL) on admission. The mortality rate was 14.4%, and mortality was associated with higher UA levels on admission (6.9 ± 2.6 mg/dL vs. 5.5 ± 2 mg/dL in patients who survived, P < 0.05). Patients who needed intensive oxygen support (high-flow nasal cannula or mechanical ventilation) and those who required longer-than-average hospitalization (> 7 days) had more hyperuricemia (intensive oxygen support: 30% vs. 18%, P = 0.07; long hospitalization 29% vs. 16.2%, P < 0.05).Conclusion: Our findings show that high UA levels are associated with adverse outcomes in patients hospitalized for COVID-19. We suggest evaluating hyperuricemia as a marker that integrates and reflects both poor prognostic baseline characteristics and acute components such as inflammatory state, hypovolemic state, and renal failure.

Objective: We aimed to characterize the course of COVID-19 in autoimmune inflammatory rheumatic disease (AIIRD) patients in Israel, taking into consideration several remarkable aspects, including the outcomes of the different outbreaks, the effect of vaccination campaigns, and AIIRD activity post-recovery. Methods: We established a national registry of AIIRD patients diagnosed with COVID-19, including demographic data, AIIRD diagnosis, duration and systemic involvement, comorbidities, date of COVID-19 diagnosis, clinical course, and dates of vaccinations. COVID-19 was diagnosed by a positive SARS-CoV-2 polymerase chain reaction. Results: Israel experienced 4 outbreaks of COVID-19 until 30.11.2021. The first three outbreaks (1.3.2020 - 30.4.2021) comprised 298 AIIRD patients. 64.9% had a mild disease and 24.2% had a severe course; 161 (53.3%) patients were hospitalized, 27 (8.9%) died. The 4th outbreak (delta variant), starting 6 months after the beginning of the vaccination campaign comprised 110 patients. Despite similar demographic and clinical characteristics, a smaller proportion of AIIRD patients had negative outcomes as compared to the first 3 outbreaks, with regards to severity (16 patients,14.5%), hospitalization (29 patients, 26.4%) and death (7 patients, 6.4%). COVID-19 did not seem to influence the AIIRD activity 1-3 months post-recovery. Conclusions: COVID-19 is more severe and has an increased mortality in active AIIRD patients with systemic involvement, older age and comorbidities. Vaccination with 3 doses of the mRNA vaccine against SARS-CoV-2 protected from severe COVID-19, hospitalization and death during the 4th outbreak. The pattern of spread of COVID-19 in AIIRD patients was similar to the general population.

BACKGROUND: Social distancing was the predominant strategy used to mitigate the spread of Coronavirus disease 2019 (COVID-19) at the start of the COVID-19 pandemic. AIMS: To study the impact of social distancing on the incidence of bacteraemia. The number of admitted patients with positive blood cultures in April-May 2020 in one tertiary medical centre was compared with the number during the same period in the previous 3 years (April-May 2017-2019). METHODS: Retrospective review of all positive blood cultures from January to July in the years 2017-2020. RESULTS: There were fewer cases of Streptococcus bacteraemia as well as coagulase-negative Staphylococcus bacteraemia and other possible contaminated blood cultures in April-May 2020. Compared with the previous 3 years, the incidence of Streptococcus pneumoniae bacteraemia among all bacteraemias was lower in April-May 2020 (5%) than in 2017-2019 (12.0%; 95% confidence interval 10.3-14.1%). In general, fewer cases of bacteraemia caused by oropharynx organisms were observed in April-May 2020; only 6 cases versus 31 (95% confidence interval 10-53) during the same period in 2017-2019. Only one case of S. pneumoniae bacteraemia was observed in April-May 2020 and its percentage among all bacteraemias was lower in April-May 2020 (0.4%) than during the same period in 2017-2019 (3.3%). CONCLUSION: The incidences of streptococcal bacteraemia and bacteraemia of organisms transmitted through respiratory secretions were lower when there were social distancing restrictions. Adopting measures of social distancing may decrease the morbidity from bacteraemia caused by oropharynx and respiratory bacteria.

CONTEXT: Bilateral adrenal hemorrhage is a rare condition with potentially life-threatening consequences such as acute adrenal insufficiency. Early adrenal axis testing, as well as directed imaging, is crucial for immediate diagnosis and treatment. Coronavirus disease 2019 (COVID-19) has been associated with coagulopathy and thromboembolic events. CASE DESCRIPTION: A 66-year-old woman presented with acute COVID-19 infection and primary adrenal insufficiency due to bilateral adrenal hemorrhage (BAH). She also had a renal vein thrombosis. Her past medical history revealed primary antiphospholipid syndrome (APLS). Four weeks after discharge she had no signs of COVID-19 infection and her polymerase chain reaction test for COVID-19 was negative, but she still needed glucocorticoid and mineralocorticoid replacement therapy. The combination of APLS and COVID-19 was probably responsible of the adrenal event as a "two-hit" mechanism. CONCLUSIONS: COVID-19 infection is associated with coagulopathy and thromboembolic events, including BAH. Adrenal insufficiency is life threatening; therefore, we suggest that early adrenal axis testing for COVID-19 patients with clinical suspicion of adrenal insufficiency should be carried out.

A young female presented to the emergency room with ruptured hemorrhagic corpus luteum (RHCL). Her workup revealed a new diagnosis of SLE with nephritis and positive lupus anticoagulant (LAC) test without thrombocytopenia. We reviewed the literature and found one similar case of a 23-year-old subject who presented with a RHCL that was found to be the presenting symptom of SLE; unlike the current case, the patient presented with severe anemia (Hg 6.7 g/dl) and thrombocytopenia (10,000/ml). Possible mechanisms are discussed.

BACKGROUND: Hyperuricemia is associated with the development, progression and outcome of several diseases. The purpose of this study is to evaluate the serum uric acid (UA) levels as a predictor of long-term mortality in an older population (age 60 years and above). MATERIALS AND METHODS: Patients older than 60 years who were hospitalized in the departments of geriatrics and internal medicine in Shaare Zedek Medical Center in Jerusalem during a period of 4 months (March-June 2014) were included in this observational study. Association between hyperuricemia and long-term mortality were analyzed using multiple logistic regression, Kaplan-Meier and Cox proportional hazards regressions analysis. RESULTS: A total of 624 patients were included in our study with mean age of 77.2 ± 14.6 years. Overall, 381 patients died during the follow-up period (61.1%). Mortality rate in the hyperuricemic group (> 7 mg/dL) was higher (69.1%) than in the normouricemic group 58.4%. (Pâ¯=â¯0.004). The median survival for hyperuricemic patients was significantly shorter compared to normouricemic patients (606 and 1018 days, respectively, P < 0.0001). High levels of UA were significantly associated with higher long-term mortality in patients with cardiovascular disease at their admission (P < 0.000). CONCLUSIONS: Elevated levels of UA in older patients in acute settings is a predictor of long-term mortality.

OBJECTIVES: Epidemiologic studies differ regarding overall survival in giant cell arteritis (GCA). In this review we evaluated longevity and the impact of several disease parameters on survival of GCA patients. METHODS: Review of the medical literature during the period 1975-2018, using PubMed database. RESULTS: Epidemiologic studies addressing the issue of survival in GCA patients used variable methods of calculating mortality rates in relation to background population or in relation to selected controls. Several epidemiologic studies found that survival of GCA patients was similar to that of the general population. Others reported increased mortality in patients with GCA, or in subgroups of GCA patients. 5-Year and 10-year survival rates differed considerably among studies: 5-year survival rates ranged between 60-90% (except for 2 extremes of 35% and 97%), and 10-year survival rates ranged between 48-81%. Reasons for these discrepancies are unclear, and may be related to differences in populations, in the period of the study, and in study methods. Several studies found that mortality was increased in female GCA patients, and some reported increased mortality early in the course of the disease (mostly within the first 2 years after diagnosis). The deleterious effect of vision loss on survival was noted in a few studies, although most studies did not address the issue of mortality in this particular subgroup of GCA patients. CONCLUSIONS: Epidemiologic studies varied considerably in the reported outcomes of GCA patients: some found that the overall survival was similar to that of the general population while others reported increased mortality in GCA or in subgroups of GCA patients.

OBJECTIVES: Segmental arterial mediolysis (SAM) is a rare vasculopathy of unknown aetiology. It is non-atherosclerotic, non-inflammatory, non-hereditary, non-infectious, large to medium-sized arteriopathy. SAM is a condition which in some circumstances behaves as a vasculitis mimicker and should be recognised in order to provide appropriate treatment and avoid unnecessary immune-suppressive therapy. METHODS: We report a single-centre experience of 6 consecutive SAM cases (3 males and 3 females). A literature search of cases reported with SAM was performed and data summarised. RESULTS: Abdominal or flank pain was the presenting symptom in 5 of the 6 patients. CT angiography (CTA) was the method of diagnosis in all 6 patients. 3 patients underwent therapeutic angiography; 2 with angiographic embolisation because of bleeding, and one patient needed a stent insertion because of left renal infarction. 2 patients underwent FDG-PET to rule out vasculitis. Serological tests were negative in all case, but C-reactive protein was elevated in 4 of them. 2 patients were treated with angiographic embolisation due to bleeding, 2 treated with anti-platelet therapy, one with stent insertion, and one with antihypertensive treatment. A medical literature review of 160 additional cases shows that abdominal or flank pain was the chief complaint in the vast majority of the cases. Renal and abdominal medium-sized arteries were the most commonly involved. CTA was the preferred method of diagnosis. CONCLUSIONS: SAM should be suspected in cases presenting with abdominal or flank pain. Angiographic features should be carefully studied by experienced radiologists to rule out vasculitis.

OBJECTIVES: Bacteriological diagnosis of septic arthritis (SA) is complicated. Agar plates are the main culture method and yields 40-60% of positive bacterial detection. Addition of bottled culture broth (Bactec®) as a method for detecting synovial microorganisms is common. The advantages of this method and the combination of both have not been thoroughly investigated. This study evaluates an added value of the Bactec culture broth as a single method or as combined with the agar-plate culture. METHODS: All culture aspirates of SA-suspected patients were analyzed. All cases with a positive result by either method were reviewed for background data and clinical diagnosis. RESULTS: Out of 5000 synovial fluid samples, a clinical diagnosis of SA was suspected in 1024 cases. Samples processed by both culture methods were extracted during the same event. Bactec® vials were positive for significant bacterial detection in 113/148 cases (76.4%) while agar-plate cultures were positive in only 96/154 (62.3%) representing higher sensitivity of 0.5 vs. 0.42 and a positive predictive value (PPV) of 0.76 vs. 0.62. Bacterial detection by both methods combined was positive in 137/221 (62%) and did not achieve a significant increment. CONCLUSIONS: The Bactec® method has many advantages in bacteriological identification of synovial infection, including a broader identification spectrum, faster response time, and superior qualities of identification although being more expensive. This method has a better yield in detecting septic arthritis and might be considered a single method for synovial fluid culture in cases suspected for SA.Key Points⢠The Bactec method had improved detection rates.⢠Culturing by agar plates and Bactec revealed higher sensitivity and lower specificity.⢠The use of the blood culture bottles (Bactec system) alone will raise the detection rate of septic arthritis with lower false positive rates and at lower costs.

ABSTRACT
BACKGROUND & AIMS: Acute hepatitis C (AHC) is not frequently identified because patients are usually asymptomatic, although may be recognized after iatrogenic exposures such as needle stick injuries, medical injection, and acupuncture. We describe an outbreak of AHC among 12 patients who received IV saline flush from a single multi-dose vial after intravenous contrast administration for a computerized tomography (CT) scan. The last patient to receive IV contrast with saline flush from a multi-dose vial at the clinic on the previous day was known to have chronic HCV genotype 1b (termed potential source, PS). Here we sought to confirm (via genetic analysis) the source of infection and to predict the minimal contaminating level of IV saline flush needed to transmit infectious virus to all patients. METHODS: In order to confirm the source of infection, we sequenced the HCV E1E2 region in 7 CT patients, in PS, and in 2 control samples from unrelated patients also infected with HCV genotype 1b. A transmission probabilistic model was developed to predict the contamination volume of blood that would have been sufficient to transmit infectious virus to all patients. RESULTS: Viral sequencing showed close clustering of the cases with the PS. The transmission probabilistic model predicted that contamination of the multi-dose saline vial with 0.6-8.7 microliters of blood would have been sufficient to transmit infectious virus to all patients. CONCLUSION: Analysis of this unique cohort provides a new understanding of HCV transmission with respect to contaminating volumes and viral titers.

Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are both more common among people of North European decent than among Mediterranean people. Women are 2-3 times more commonly affected. Giant cell arteritis and PMR are extremely rare before age 50 years. Polymyalgia rheumatica may be "isolated" or associated with GCA. There is increased expression of inflammatory cytokines in temporal arteries of PMR patients, without overt histological evidence of arteritis. One-third of "isolated" PMR patients have vascular uptake in positron emission tomography (PET) scans, suggesting clinically unrecognized, "hidden" GCA. Typical manifestations of GCA are headache, tenderness over temporal arteries, jaw claudication, PMR, acute vision loss, and low-grade fever. Bilateral aching of the shoulders with morning stiffness is typical for PMR. In both conditions sedimentation rate and C-reactive protein are elevated, and anemia and thrombocytosis may occur. Color duplex ultrasonography of the temporal arteries may aid in GCA diagnosis. Temporal artery biopsy showing vasculitis, often with giant cells, confirms GCA diagnosis. In cases with negative biopsy one must rely on the clinical presentation and laboratory abnormalities. The diagnosis of PMR is made primarily on clinical grounds. Other conditions that may mimic GCA or PMR must be excluded. Glucocorticoids are the treatment of choice for both conditions. Prompt treatment is crucial in GCA, to prevent irreversible complications of acute vision loss and stroke. Addition of low-dose aspirin may further prevent these complications. The average duration of treatment is 2-3 years, but some patients require a prolonged course of treatment, and some may develop disease-related or treatment-related complications. No steroid-sparing agent has been proven to be widely effective thus far, but some promising therapeutic agents are currently being studied.
ABSTRACT
AIM: The aim of this study is to evaluate the diagnostic yield of dual-energy computed tomography (DECT) in detection of uric acid accumulation in joints or periarticular structures in patients suspected of having gout, in their intercritical period. METHODS: Patients with a history of recurrent, short-lived mono- or oligo-arthralgia or arthritis, referred to the rheumatology clinic for diagnosis of their condition, were included in this retrospective evaluation. RESULTS: DECT confirmed the diagnosis of gout in 30 of 50 patients (60%). A positive DECT was present in 12 of 16 cases (75%) with serum uric acid > 8.5 mg/dL, compared to seven of 13 cases (54%) and two of five cases (40%) with levels of 6.1-8.5 mg/dL and ≤ 6 mg/dL, respectively. The diagnostic impact of screening hands and feet were highest (78% and 56%, respectively). Follow-up data were available for 24 of the 30 patients with urate deposits identified by DECT. Twenty-one were treated with urate-lowering agents, all responded with lowering of serum uric acid and cessation of flares. Follow-up data were available for 16 of the 20 patients with no urate deposits identified by DECT. Gout was diagnosed in two of them by synovial fluid examination during subsequent flares. Both positive and negative predictive values of DECT for diagnosing gout in this patient population were 87%. Following DECT, treatment regimen was modified to gout-specific therapy in 52% of the patients. DISCUSSION: The ability to make a definite diagnosis of gout by DECT imaging in a substantial number of asymptomatic patients in the intercritical period should help in treatment decision-making and improve patient adherence to long-term urate-lowering therapy.

The current study examined how functional and existential coping factors are related to the sense of self-benefit among end-of-life (EOL) family caregivers caring for hospitalized older adults. A convenience sample of 92 family caregivers was interviewed in two Israeli hospitals using a structured questionnaire based on Pearlin's stress process model. Findings show that engagement in EOL existential tasks and motivations, such as life review, spirituality, multigenerational family relationships, and preparation for death, acted as a coping resource and was positively related with caregivers' sense of self-benefit. However, functional caregiving did not act as a significant stressor, as it was weakly related to care-givers' sense of self-benefit. Findings discuss the importance of training health professionals to recognize and discuss existential concerns with EOL family caregivers. [Journal of Gerontological Nursing, 42(7), 55-64.].
