Impact of Hepatitis B virus infection on postoperative complications and length of stay in elderly patients with hip fracture: A retrospective cohort study. Injury 2023:S0020-1383(23)00453-9. [PMID: 37198044 DOI: 10.1016/j.injury.2023.05.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 03/28/2023] [Accepted: 05/10/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND Osteoporosis and subsequent fractures are common in the chronic hepatitis B (CHB) population, especially in the elderly. This study investigated the effects of hepatitis B virus (HBV) infection on postoperative outcomes following hip fracture surgery. METHODS The study identified elderly patients who underwent hip fracture surgery at three academic tertiary care centres between January 2014 and December 2020. Propensity score matching was performed to compare the outcomes of 1,046 patients with HBV infection to 1,046 controls. RESULTS The seroprevalence of HBV among elderly patients undergoing hip surgery was 4.94%. The HBV cohort had significantly higher rates of medical complications (28.1 vs. 22.7%, p = 0.005), surgical complications (14.0 vs. 9.7%, p = 0.003), and unplanned readmissions (18.9 vs. 14.5%, p = 0.03) within 90 days of surgery. Patients with HBV infection were more likely to have increased length of stay (6.2 vs. 5.9 days, p = 0.009) and in-hospital charges (¥52,231 vs. ¥49,832, p < 0.00001). Multivariate logistic regression suggested that liver fibrosis and thrombocytopenia were independent risk factors for major complications and extended LOS. CONCLUSION Patients with HBV infection were at greater risk of adverse postoperative outcomes. We should pay more attention to the considerable burden of perioperative management of CHB patients. Due to the high proportion of undiagnosed patients in the Chinese elderly population, universal HBV screening should be considered preoperatively.

Abstract
BACKGROUND Previous studies have shown that chronic hepatitis B virus (HBV) infection may place patients at increased risk of postoperative adverse events. However, there is limited information on the effects of antiviral treatment (AVT) on postoperative outcomes following total hip arthroplasties (THAs). METHODS A multicenter retrospective database query was used to identify patients infected with HBV undergoing THAs between 2012 and 2017. All eligible patients were divided into 2 cohorts on the basis of AVT before surgery: the treated group and the untreated group. The treated cohort was matched at a ratio of 1:3 to the untreated cohort by propensity score matching. Operating times, blood losses, all-type complications, surgical complications, lengths of stay, 90-day readmissions, unplanned reoperations, and implant revisions were compared between the 2 cohorts. After these patients were further stratified by liver fibrosis status, multivariate logistic analyses were performed by controlling for differences in demographics and comorbidities. In total, 918 patients chronically infected with HBV were identified. Over four-fifths of these patients (83.0%) did not receive preoperative AVT. Of interest, more than half of the untreated patients (54.1%) were previously undiagnosed. RESULTS The untreated group had significantly longer mean operating time (82 versus 76 minutes, P = .007) and higher mean blood loss (515 versus 465 mL, P = .03) than the treated group. Moreover, they were more prone to experiencing surgical complications (25.4% versus 16.7%, P = .01), longer lengths of stay (6.2 versus 5.4 days, P = .0005), readmissions (12.4% versus 5.8%, P = .02), reoperations (16.7% versus 9.6%, P = .03), and revisions (11.1% versus 4.5%, P = .02). Multivariate regression analyses found that AVT significantly decreased all-type complications, reoperations, and revisions in patients with significant fibrosis (all P < .05). CONCLUSION The AVT of HBV infection prior to THAs could reduce the risk of developing postoperative complications, regardless of the presence of liver fibrosis. This finding emphasizes that surgeons should recommend HBV screening and treatment integrated into preoperative medical optimization.

Abstract
BACKGROUND Whether hepatitis C virus (HCV)-positive patients are at risk for increased complications and long hospital stay following total joint arthroplasty (TJA) remains unclear. Therefore we performed a meta-analysis aiming to answer the following question: (1) are there differences in postoperative complications including joint infection and mortality between patients with or without hepatitis C following TJAs? (2) Are patients without HCV be associated with less blood loss, shorter hospital stay, lower readmission rate, higher function scores, lower revision and reoperation rates than patients with HCV? METHODS A meta-analysis was conducted to pool data and quantitatively assessing the association between HCV infection and risks for adverse postoperative outcomes. A systematic search of all published studies concerning HCV and TJA was performed in five bibliographic databases, including PubMed, EMBASE, China National Knowledge Infrastructure, Web of Science, and the Cochrane Library databases. Random-effects meta-analysis of odds ratios (OR) was accomplished according to the classification of adverse events, subgroup analyses were performed based on surgery type. RESULTS Fifteen eligible observational studies were included with a sample size of 9,788,166 patients. Overall pooled data revealed the increased risk of overall complications, including medical and surgical complications, in HCV-positive patients undergoing TJA compared with than in HCV-negative people (OR 1.57; 95%CI: 1.44-1.71 [p<0.00001]). Joint infections were highly common in HCV-positive patients undergoing lower-extremity TJA (OR 2.06; 95%CI: 1.73-2.47 [p<0.00001]). Furthermore, HCV infections were associated with high rates of reoperations and revisions (OR 1.47; 95%CI: 1.40-1.55 [p<0.00001]). CONCLUSIONS Patients with hepatitis C have an increased risk of adverse outcomes post-TJA and a high risk of reoperation and revision that is partially attributed to postoperative complications, particularly joint infections.

Abstract
OBJECTIVE Needlesticks are common work-related injuries suffered by health care professionals. We sought to identify prevalence of needlestick/sharps injuries of residents working in the operating room and identify contributing factors and barriers to reporting/seeking treatment. METHODS A 17-question survey on needlestick injuries was distributed to 168 residents in anesthesiology, surgery, and surgical subspecialties and the responses were analyzed for statistical significance of differences observed between departments. RESULTS Of 138 respondents (82% response rate), 49% of residents had at least one needlestick injury during training. One quarter did not report their injuries to employee health or seek treatment, with the largest percentage from general surgery (53%). The primary reasons for not reporting injuries or seeking treatment included time away from patient care and lack of concern about the injury. More than half (64%) of the anesthesiology residents who reported an injury thought fatigue was a contributing factor. CONCLUSIONS Half of residents sustained an injury and a quarter of injuries did not get reported, with the most valid reason being too much time away from patient care. Only anesthesiology residents commonly cited fatigue as a contributor to their needlestick/sharps injury. Understanding the program-specific needlestick/sharps injury incidence and prevalence, and the attitudes about reporting injuries and seeking treatment, is a first step toward prevention of injury for residents in training.

Abstract
INTRODUCTION Health-care workers, especially medical intern, are at risk of exposed to blood and other body fluids in the course of their work. To reduce the risk, standard precaution (SP) is introduced. Among all communicable diseases that could be transmitted, human immunodeficiency virus (HIV) is the most stigmatized disease. However, there are some government hospitals that separated adult HIV patients with other patients to prevent additional infection. This study aims to evaluate the impact of ward separation on SP adherence. MATERIALS AND METHODS This was an observational study conducted in March 2017 in a tertiary referral hospital for the eastern part of Indonesia. The participants were 150 medical students who underwent the past year of their clinical rotation. They were given a three-part questionnaire, consisting of their background, their SP practice in the HIV ward and non-HIV wards, and their perception and attitude regarding SP. McNemar's test and Fisher's exact test were used for the statistical analysis, using SPSS version 23.0 for Windows. RESULTS Participants were more adhered to SP (hand hygiene, wear mask as indicated, and wear glove as indicated) in the HIV ward compare to non-HIV wards (P = 0.002, P = 0.001, and P = 0.001, respectively). Almost all participants were more careful in implementing SP in the HIV ward than in non-HIV wards and were more concerned of getting needlestick injury in the HIV ward than in non-HIV ward. CONCLUSION HIV and non-HIV ward separation negatively impact medical students' SP adherence.

Abstract
Aim: The aim was to assess the seroprevalence of Human Immunodeficiency Virus (HIV) in non-haemophilic patients undergoing primary Total Joint Arthroplasty (TJA) at an academic hospital in South Africa. Methods: A retrospective review of all Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA) patients from January 2017 to December 2018 was conducted. All patients awaiting TJA were offered HIV screening and their demographic data were recorded. Consenting patients were tested or the refusal of testing was documented. The CD4+ T-cell count (CD4+) and viral load (VL) was measured for all HIV-positive patients and newly diagnosed patients were initiated on Highly Active Antiretroviral Treatment (HAART). Results: We included 1007 patients in the study. The TJA population HIV seroprevalence was 10.7% (n = 108). The seroprevalence for THA was 14.9% (n = 78) and that for TKA was 6.2% (n = 30). There were 93 patients (9.2%) who refused screening. There were 12 (15.4%) and 3 patients (10%) that were newly diagnosed in the THA and TKA seropositive populations, respectively. The average CD4+ for THA and TKA was 569 cells/mm3 (105–1320) and 691 cells/mm3 (98–1406), respectively. The VL was undetectable in 75.9% (n = 82) of HIV-positive patients. Overall 12 HIV-positive patients (11.12%) had CD4+ <200 cells/mm3, 8 of these patients (66%) were newly diagnosed. The average age of the seropositive population was 58 ± 6.5 years and 66 ± 8.5 years for THA and TKA, respectively (p = 0.03). Femoral head osteonecrosis was the underlying pathology for 65.38% (n = 51) of seropositive patients for THA. Conclusion: The seroprevalence of HIV in patients undergoing THA in our South African institution is greater than the seroprevalence in the general population. The seroprevalence of HIV in THA is significantly greater than that in TKA. This may reflect the association between HIV, HAART and hip joint degeneration. Our findings draw attention to the significant burden HIV has on TJA.

Abstract
BACKGROUND To prevent the transmission of HIV and hepatitis B and C viruses, early detection is necessary; however, in the early stage, most infected people are symptomless. Screening for these infections should be targeted to certain clinical settings to increase the early detection rate. MATERIAL AND METHODS This retrospective study was conducted by analyzing data from patients' medical records to determine how the screening tests for these viral infections were utilized and what the clinical outcomes from the test utilization were. RESULTS From 11 676 collected records, the screening tests for HIV, HBV, and HCV infections were utilized in 871, 556, and 236 cases, respectively. The tests for HIV and HCV were utilized the most in people with chronic non-infectious diseases, while the test for HBV infection was utilized the most in pregnant women. The positive results of these tests were highly found in the group of patients with acute non-infectious diseases. HIV infection was newly detected in 1.38% of patients, and HBV and HCV infections were newly detected in 5.58% and 2.12%, respectively. CONCLUSIONS Screening for HIV and HBV infections was performed according to the guidelines of the national HIV and HBV programs. The Outpatient Department (OPD) and medical ward may be the most appropriate clinical settings for HIV screening because most patients are there and blood tests are often ordered there, too. The national programs helped slow the rates of HIV and HBV infections in this community.

Abstract
Objectives Prosthetic joint infection (PJI) is the most common cause of arthroplasty failure. However, infection is often difficult to detect by conventional bacterial cultures, for which false-negative rates are 23% to 35%. In contrast, 16S rRNA metagenomics has been shown to quantitatively detect unculturable, unsuspected, and unviable pathogens. In this study, we investigated the use of 16S rRNA metagenomics for detection of bacterial pathogens in synovial fluid (SF) from patients with hip or knee PJI. Methods We analyzed the bacterial composition of 22 SF samples collected from 11 patients with PJIs (first- and second-stage surgery). The V3 and V4 region of bacteria was assessed by comparing the taxonomic distribution of the 16S rDNA amplicons with microbiome sequencing analysis. We also compared the results of bacterial detection from different methods including 16S metagenomics, traditional cultures, and targeted Sanger sequencing. Results Polymicrobial infections were not only detected, but also characterized at different timepoints corresponding to first- and second-stage exchange arthroplasty. Similar taxonomic distributions were obtained by matching sequence data against SILVA, Greengenes, and The National Center for Biotechnology Information (NCBI). All bacteria isolated from the traditional culture could be further identified by 16S metagenomics and targeted Sanger sequencing. Conclusion The data highlight 16S rRNA metagenomics as a suitable and promising method to detect and identify infecting bacteria, most of which may be uncultivable. Importantly, the method dramatically reduces turnaround time to two days rather than approximately one week for conventional cultures. Cite this article: M-F. Chen, C-H. Chang, C. Chiang-Ni, P-H.

Abstract
BACKGROUND Early diagnosis of hepatitis C virus (HCV) infection is very important for the treatment of the disease. Development of sensitive and specific rapid detection assays is of great significance for the diagnosis. Here, we describe a promising method of using gold-labeled streptavidin fusion proteins as novel signal reporter in a rapid detection assay for HCV infection. METHODS Recombinant genes encoding streptavidin fused with Escherichia coli maltose-binding protein (MBP) or with a portion of bacterial translational initiation factor 2 were cloned in expression vectors pMAL-5CX and pET28 and transformed in proper Escherichia coli host strains. The genes were induced and streptavidin fusion proteins, named M-STV and IF-STV, respectively, were purified by affinity chromatography to over 90% purity. The biotin-binding activity of M-STV and IF-STV was tested by enzyme-linked immunosorbent assay (ELISA). M-STV was labeled with colloidal gold nanoparticles and used as a signal reporter to develop a lateral flow-based rapid test for detecting anti-HCV antibodies in human blood samples. RESULTS M-STV showed slightly higher biotin-binding activity and similar binding specificity as compared to commercial streptavidin. The gold-labeled M-STV bound specifically to biotin moieties immobilized on the rapid test strips in a dose-responsive manner and was successfully used in detecting HCV antibodies in serum samples of patients infected with HCV. The rapid test displayed higher detection sensitivity than gold-labeled commercial NeutrAvidin. CONCLUSION Our results indicate that gold-labeled M-STV is a promising agent in rapid tests of HCV infection and possibly other viral infections.
