Aged-care facilities are high-risk settings for coronavirus disease 2019 (COVID-19) outbreaks because residents have risk factors such as advanced age and multiple comorbidities. This report details a COVID-19 outbreak at an aged-care facility in Selangor, Malaysia during March-April 2020.

Epidemiological and environmental data were gathered via telephone interviews and field investigations. Swab samples were taken from all residents and staff for laboratory investigation. Possible contributing factors to the outbreak were explored.

There were a total of 18 individuals at the institution nine elderly residents and nine staff. The attack rate was 66.67% (6/9) among the elderly residents and 55.56% (5/9) among the staff. The most common symptoms reported were fever, cough, shortness of breath and diarrhoea. The fatality rate among COVID-19 cases was 18.18% (2/11). Both fatal cases occurred in people of advanced age (86 and 92 years old), who had comorbidities and had fever at presentation. The factors contributing to the outbreak included a delay in isolating symptomatic residents, the use of common facilities, caregivers providing support to more than one resident and a lack of natural ventilation.

Prevention and control measures must be aggressively implemented in high-risk sites to significantly reduce the risk of morbidity and mortality during COVID-19 outbreaks. Specific guidelines should be developed detailing the management of outbreaks in institutions such as aged-care facilities.

However, it is widely documented that this patient population experiences worse health due to their military service, so it is logical that their mortality will be diminished due to their worse health. This research study helped address an apparent gap in the literature regarding the mortality of 100% service-connected U.S. veterans. The objective of this research study was to answer the question, what is the average age at death of 100% service-connected U.S. veterans? This research study is a pilot study designed to help answer this initial question. This is important because it will help determine if the mortality of this U.S. veteran population is reduced due to their military service.

Hepatosplenic candidiasis (HSC) used to be reported in patients with acute myeloid leukemia (AML) without antifungal prophylaxis. The aim was to describe the clinical features and outcomes of HSC over the last 13 years in a single French hematology center.

All patients diagnosed with HSC between 2008 and 2020 were included in a single-center retrospective cohort study. Data were collected from patient charts, and HSC was classified according to the 2020 European Organisation for Research and Treatment of Cancer/Mycoses Study Group definitions.

Sixty patients were included, with 18.3% proven, 3.3% probable, and 78.3% possible HSC according to the 2020 European Organization for Research and Treatment of Cancer Mycoses Study Group classification. Among them, 19 patients were treated for acute myeloid leukemia (AML), 21 for lymphomas, and 14 for acute lymphoblastic leukemia. HSC occurred in 13 patients after autologous stem cell transplantation for lymphoma. At HSC diagnosis, 13 patients were receiving antifungal prophylaxis.

colonization was present in 84.2%, with prior candidemia in 36.7% of cases. β-D-glucans was positive in 55.8%, and 45.8% of tissue biopsies were contributive. First-line antifungal therapy was azoles in 61.7%, and steroids were associated in 45% of cases. At 3 months of follow-up, partial response to antifungal therapy was 94.2%. At last follow-up (mean, 22.6 months), 41 patients (68.3%) presented a complete hematological remission and 22 patients were deceased, none because of HSC.

The epidemiology of HSC has changed in the last decade, with fewer cases occurring in the AML setting. A better identification of patients at risk could lead to specific prophylaxis and improved diagnosis.

The outcomes of hematogenous periprosthetic joint infection (PJI) and reasons for failure are largely unknown.

The outcomes of consecutive patients with hematogenous PJI treated at our institution between 2010 and 2019 were evaluated. Failure was classified as persistence or relapse of infection or new infection. Failure-free survival was assessed using Kaplan-Meier analysis. Proportions between groups were compared with the Fisher exact test.

One hundred thirty-two hematogenous PJI episodes involving knee (n = 76), hip (n = 54), shoulder (n = 1), or elbow (n = 1) prostheses experienced by 110 patients were included. The median follow-up (range) was 20.7 (0.2-89.9) months. Hematogenous PJIs were caused by

(n = 49),

spp. (n = 36),

(n = 17), Enterobacterales (n = 16), coagulase-negative staphylococci (n = 9), and other (n = 6). Debridement and implant retention were performed in 50 (38%), prosthesis exchange or removal in 79 (60%), and no surgery in 3 episodes (2%). Treatment failed in 42 episodeoccurred frequently, reducing treatment success to 62% after 4 years of follow-up, suggesting an individual predisposition to hematogenous PJI. The outcome was similar for different pathogens but worse in episodes treated with prosthesis retention compared with multistage exchange.

Propensity score methods are becoming increasingly popular in infectious disease medicine to correct for confounding in observational studies. However, applying and reporting propensity score techniques correctly requires substantial knowledge of these methods. The quality of conduct and reporting of propensity score methods in studies investigating the effectiveness of antimicrobial therapy is yet undetermined.

A systematic review was performed to provide an overview of studies (2005-2020) on the effectiveness of antimicrobial therapy that used propensity score methods. A quality assessment tool and a standardized quality score were developed to evaluate a subset of studies in which antibacterial therapy was investigated in detail. The scale of this standardized score ranges between 0 (lowest quality) and 100 (excellent).

A total of 437 studies were included. The absolute number of studies that investigated the effectiveness of antimicrobial therapy and that used propensity score methods increased 15-fold between the periods 2005-2009 and 2015-2019. Propensity score matching was the most frequently applied technique (65%), followed by propensity score-adjusted multivariable regression (25%). https://www.selleckchem.com/products/bapta-am.html A subset of 108 studies was evaluated in detail. The median standardized quality score per year ranged between 53 and 61 (overall range 33-88) and remained constant over the years.

The quality of conduct and reporting of propensity score methods in research on the effectiveness of antimicrobial therapy needs substantial improvement. The quality assessment instrument that was developed in this study may serve to help investigators improve the conduct and reporting of propensity score methods.

Little is known about vaccine efficacy and sustainability among people with HIV (PWH). We estimated humoral and cellular immune responses postvaccination with BNT162b2 mRNA coronavirus disease 2019 (COVID-19) vaccine among PWH in Tel-Aviv Medical Center.

The vaccine humoral response was evaluated by measuring immunoglobulin G (IgG) titers of antispike receptor-binding domain antibodies (anti-RBD IgG). Cellular response was assessed by stimulating donor peripheral blood mononuclear cells with pooled complete S-peptide mix.

One hundred thirty-six PWH who completed 2 doses of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine were tested for anti-RBD IgG and compared with 61 vaccinated health care workers (HCWs). The antibody titers were similar between the groups (median, 118 BAU/mL for PWH and 101.4 BAU/mL for HCWs;

 = .231), although the mean time from second vaccine was 4.5 months in PWH and 6.7 months in HCWs (

 < .0001). Longer time from second vaccine dose was associated with decreased antibody level, as were CD4 counts <300 cells/µL compared with higher CD4 counts (25.1 BAU/mL vs 119.3 BAU/mL, respectively;

 = .047). There was no difference in cellular immune response between vaccinated PWH, convalescent unvaccinated PWH, and vaccinated HCWs.

The humoral immune response of PWH was comparable to that of HCWs after BNT162b2 mRNA vaccination. Cellular immune response did not differ between vaccinated PWH, convalescent PWH, and vaccinated HCWs. PWH with CD4 counts <300 cells/µL (n = 9) had lower antibody titers compared with patients with counts >300 cells/µL (n = 127).

Ocular candidiasis is a known complication of candidemia. Given the poor ocular penetration of echinocandins, there is some concern that the increasing use of echinocandins may portend an increased incidence of ophthalmic complications. We examined the changing trends in antifungal prescribing patterns and the incidence of ophthalmic complications after candidemia.

Patients with blood cultures positive for

species between January 2014 and June 2020 who underwent screening fundoscopic examination by an ophthalmologist were analyzed. The χ

analysis was used to compare antifungal prescriptions and ocular exam findings before and after 2016. Trend analysis was also performed to assess temporal changes in prescribing practices and eye exam findings.

There were 226 candidemia cases during the study period, 129 (57.1%) of which underwent screening eye exams. From 2014 to 2015, 24 of 37 (64.5%) patients received eye-penetrating antifungals compared to 36 of 92 (39.1%) from 2016 to 2020 (

 = .008). Overall, 30 of 129 (23.3%) patients had abnormal eye exams with the prevalence of abnormal findings being 7 of 37 (18.9%) before 2016 compared to 23 of 92 (25%,

 = .46) thereafter. A trend analysis revealed an increase in abnormal eye findings over the study period (

 = .008). Of the 30 patients who had abnormal eye exams, 9 (30%) had a change in systemic antifungal therapy from echinocandins to eye-penetrating antifungals. Echinocandin use was associated with abnormal eye findings.

Prescription of eye-penetrating antifungals for candidemia has trended down since 2016. This was associated with a concomitant increase in abnormal findings on screening fundoscopy. Abnormal eye exams were not uncommon throughout our study period.
