Advanced care planning documents provide a patient's healthcare team and loved ones with guidance on patients' treatment preferences when they are unable to advocate for themselves. A substantial ...proportion of patients will die within a few months of experiencing a hip fracture, but despite the importance of such documents, patients undergoing surgery for hip fracture seldom have discussions documented in the medical records regarding end-of-life care during their surgical admission. To the best of our knowledge, the proportion of patients older than 65 years treated with surgery for hip fractures who have advanced care planning documents in their electronic medical record (EMR) has not been explored, neither has the association between socioeconomic status and the presence of those documents in the EMR. Determining this information can help to identify opportunities to promote advanced care planning.
(1) What percentage of patients older than 65 years who undergo hip fracture surgery have completed advanced care planning documents uploaded in the EMR before or during their surgical hospitalization, or at any timepoint (before admission, during admission, and after admission)? (2) Are patients from distressed communities less likely to have advanced care planning documents in the EMR than patients from wealthier communities, after controlling for economic well-being as measured by the Distressed Communities Index? (3) What percentage of patients older than 65 years with hip fractures who died during their hospitalization for hip fracture surgery had advanced care planning documents uploaded in the EMR?
This was a retrospective, comparative study conducted at two geographically distinct hospitals: one urban Level I trauma center and one suburban Level II trauma center. Between 2017 and 2021, these two centers treated 850 patients for hip fractures. Among those patients, we included patients older than 65 years who were treated with open reduction and internal fixation, intramedullary nailing, hemiarthroplasty, or THA for a fragility fracture of the proximal femur. Based on that, 83% (709 of 850) of patients were eligible; a further 6% (52 of 850) were excluded because they had codes other than ICD-9 820 or ICD-10 S72.0, and another 2% (17 of 850) had incomplete datasets, leaving 75% (640 of 850) for analysis here. Most patients with incomplete datasets were in the prosperous Distressed Communities Index category. Among patients included in this study, the average age was 82 years, 70% (448 of 640) were women, and regarding the Distressed Communities Index, 32% (203 of 640) were in the prosperous category, 25% (159 of 640) were in the comfortable category, 15% (99 of 640) were in the mid-tier category, 5% (31 of 640) were in the at-risk category, and 23% (145 of 640) were in the distressed category. The primary outcome included the presence of advanced care planning documents (advanced directives, healthcare power of attorney, or physician orders for life-sustaining treatment) in the EMR before surgery, during the surgical admission, or at any time. The Distressed Communities Index was used to indicate economic well-being, and patients were identified as being in one of five Distressed Communities Index categories (prosperous, comfortable, mid-tier, at-risk, and distressed) based on ZIP Code. An exploratory analysis was conducted to determine variables associated with the presence of advanced care planning documents in the EMR. A multivariate regression was then performed for patients who did or did not have advanced care planning documents in their medical record at any time. The results are presented as ORs with the associated 95% confidence interval (CI).
Nine percent (55 of 640) of patients had advanced care planning documents in the EMR preoperatively or during their surgical admission, and 22% (142 of 640) of patients had them in the EMR at any time. After controlling for potential confounding variables such as age, laterality (left or right hip), hospital type, and American Society of Anesthesiologists (ASA) classification, we found that patients in Distressed Communities Index categories other than prosperous had ORs lower than 0.7, with patients in the distressed category (OR 0.4 95% CI 0.2 to 0.7; p < 0.01) and comfortable category (OR 0.5 95% CI 0.3 to 0.9; p = 0.01) having a substantially lower odds of having advanced care planning documents in their EMR. Patients aged 86 to 95 years (OR 1.9 95% CI 1.1 to 3.4), those 96 years and older (OR 4.0 95% CI 1.7 to 9.5), and those with a higher ASA classification (OR 1.6 95% CI 1.1 to 2.3) had a higher odds of having advanced care planning documents in the EMR at any time. Among 14 patients who experienced in-hospital mortality, two had advanced care planning documents uploaded into their EMR, whereas 12 of 14 who died in the hospital did not have advanced care planning documents uploaded into their EMR.
Orthopaedic surgeons should counsel patients regarding the risk for postoperative complications after fragility hip fracture surgery and engage in shared decision-making regarding advanced care planning documents with patients or, if the patients are unable, with their families. Additionally, implementing virtual education about advanced care planning documents and using easy-to-read forms may facilitate the completion of advanced care planning documents by patients older than 65 years, especially patients with low economic well-being. Limitations of this study include having a restricted number of patients in the at-risk and mid-tier Distressed Communities Index categories and a restricted number of patients identifying as non-White races/ethnicities. Future research should evaluate the effect of advanced care document presence in the EMR on end-of-life care intensity in patients treated for fragility hip fractures.
Level III, therapeutic study.
Orthopedic surgeons experience significant musculoskeletal pain and work-related injuries while performing total joint arthroplasty (TJA). We sought to investigate the impact of operative extremity ...and surgeon limb dominance on surgeon physiologic stress and energy expenditure during TJA.
This was a prospective cohort study conducted at a tertiary academic practice. Cardiorespiratory data was recorded continuously in 3 high-volume arthroplasty surgeons using a smart garment that measured heart rate (HR), HR variability, respiratory rate, minute ventilation, and energy expenditure (calories) during conventional total knee (TKA) and total hip arthroplasty (THA).
Surgeon 1 and 2 (right-handed) performed 21 right TKAs, 10 left TKAs, 13 right THAs, and 10 left THAs. Surgeon 3 (left-handed) performed 6 right TKAs, 9 left TKAs, 16 right THAs, and 10 left THAs. While performing TKA or THA, limb laterality had no significant impact on operative time and no significant differences existed in HR, HR variability, respiratory rate, minute ventilation, or energy expenditure for any right-handed or left-handed surgeons, regardless of the operative limb laterality. While performing TKA, consistently standing on the side of hand dominance was associated with decreased strain and stress, compared to always standing on the operative side.
This study suggests that surgeon hand dominance and operative limb laterality do not impact energy expenditure or physiologic strain during TJA. However, consistently standing on the side of hand dominance in TKA may lead to decreased physiologic strain and stress during surgery. Further study utilizing wearable technology during TJA may provide orthopedic surgeons with information about modifiable factors that contribute to differences in physiological parameters during surgery.
Despite more than 20 years of combination antiretroviral therapy (cART), complete eradication of HIV remains a daunting task. While cART has been very effective in limiting new cycles of infection ...and keeping viral load below detectable levels with partial restoration of immune functions, it cannot provide a cure. Evidently, the interruption of cART leads to a quick rebound of the viral load within a few weeks. These consistent observations have revealed HIV ability to persist as an undetectable latent reservoir in a variety of tissues that remain insensitive to antiretroviral therapies. The ‘Block-and-Lock’ approach to drive latent cells into deep latency has emerged as a viable strategy to achieve a functional cure. It entails the development of latency-promoting agents with anti-HIV functions. Recent reports have suggested sulforaphane (SFN), an inducer of NRF-2 (nuclear erythroid 2-related factor 2)-mediated antioxidative signaling, to possess anti-HIV properties by restricting HIV replication at the early stages. However, the effect of SFN on the expression of integrated provirus remains unexplored. We have hypothesized that SFN may promote latency and prevent reactivation. Our results indicate that SFN can render latently infected monocytes and CD4+ T cells resistant to reactivation. SFN treatments antagonized the effects of known latency reactivating agents, tumor necrosis pactor (TNF-α), and phorbol 12-myristate 13-acetate (PMA), and caused a significant reduction in HIV transcription, viral RNA copies, and p24 levels. Furthermore, this block of reactivation was found to be mediated by SFN-induced NRF-2 signaling that specifically decreased the activation of NFκB signaling and thus restricted the HIV-1 promoter (5′LTR) activity. Overall, our study provides compelling evidence to highlight the latency-promoting potential of SFN which could be used in the ‘Block-and-Lock’ approach to achieve an HIV cure.
There are myriad strategies to reduce opioid consumption after total knee arthroplasty (TKA). Recent studies have suggested that preoperative counseling may reduce opioid use after a variety of ...orthopedic procedures. The purpose of this study was to investigate whether preoperative video-based patient education regarding opioid use and abuse reduces opioid consumption after TKA.
In this prospective randomized controlled trial, patients were randomized before TKA to either receive preoperative video-based counseling or not. Counseling involved a pretaped 5-minute video that educated patients on statistics regarding the “opioid epidemic” and discussed safe use and alternatives to opioids after TKA. There were no significant differences in baseline patient demographics between groups. All patients received a similar multimodal perioperative pain management protocol and completed a daily diary for 2 weeks postoperatively. Diary records measured pain levels using a visual analog score, opioid consumption, side effects experienced, and patient opinion and satisfaction regarding their pain control.
Patients in the counseling group consumed significantly less morphine milligram equivalents on postoperative days 0 to 3 (78.8 versus 106.1, P = .020) and in week one postoperatively (129.9 versus 180.7, P = .028), with a trend of less consumption over 2 weeks postoperatively (186.9 versus 239.1, P = .194). There were no significant differences in the number of patients requiring refills, side effects, or daily pain levels between the 2 groups.
This study found significantly decreased opioid consumption within the first week after TKA in patients who received preoperative video counseling.
The rate of using robotic-assisted total knee arthroplasty (RA-TKA) has increased markedly. Understanding how patients view the role of robotics during total knee arthroplasty (TKA) informs shared ...decision making and facilitate efforts to appropriately educate patients regarding the risks and benefits of robotic assistance.
A self-administered questionnaire was completed by 440 potential TKA patients at the time of their surgery scheduling. Participants answered 25 questions regarding RA-TKA, socioeconomic factors, and their willingness to pay (WTP) for RA-TKA. Logistic regressions were used to determine if population characteristics and surgeon preferences influenced the patients’ perceptions of RA-TKA.
There were 39.7% of respondents who said that they had no knowledge regarding RA-TKA. Only 40.7% of participants had expressed a desire for RA-TKA to be used. There were 8.7% who were WTP extra for the use of RA-TKA. Participants believed that the main 3 benefits of RA-TKA compared to conventional methods were: more accurate implant placement (56.2%); better results (49.0%); and faster recovery (32.1%). The main 3 patient concerns were harm from malfunction (55.2%), reduced surgeon role in the procedure (48.1%), and lack of supportive research (28.3%). Surgeon preference of RA-TKA was associated with patient’s willingness to have RA-TKA (odds ratio 4.60, confidence interval 2.98-7.81, P < .001), and with WTP extra for RA-TKA (odds ratio 2.05, confidence interval: 1.01-4.26, P = .049).
Patient knowledge regarding RA-TKA is limited. Nonpeer-reviewed online information may make prospective TKA candidates vulnerable to misinformation and aggressive advertising. The challenge for orthopaedic surgeons is to re-establish control and reliably educate patients about the proven advantages and disadvantages of this emerging technology.
Fungi are increasingly recognized as major clinical pathogens in critically ill patients. Emerging groups of fungal pathogens such as
Candida
and
Cryptococcus
spp. are most frequently isolated from ...clinical setup, including filamentous fungi. Assessment of risk factors of these infections such as hospital-acquired fungal infection and environmental factors, including changes in medical practices and epidemiology as well as fungal infection mediated immunomodulation have provided important therapeutic options in the diagnosis of the fungal infections for clinicians. This review aims to furnish information on the factors affecting invasive fungal infections in a clinical scenario, especially for immunocompromised patients. A review of the recently published literature via PubMed, Elsevier and Medline database was performed. Relevant invasive fungal diseases and their worldwide cases were reviewed. Data on the immune response to the fungal infections in terms of release of anti-fungal effectors have been provided. Information on the anti-fungal mechanistic action via upregulation of immunity through predominant cytokines has been summarized, as well as factors affecting disease scenario of invasive fungal infections in clinical practices. The epidemiology and clinical features of fungal infections have also been reviewed.
The COVID-19 pandemic has become a significant global issue in terms of public health. While it is largely associated with respiratory complications, recent reports indicate that patients also ...experience neurological symptoms and other health issues. The objective of this study is to examine the network of protein-protein interactions (PPI) between SARS-CoV-2 proteins and human host proteins, pinpoint the central genes within this network implicated in disease pathology, and assess their viability as targets for drug development.
The study adopts a network-based approach to construct a network of 29 SARS-CoV-2 proteins interacting with 2896 host proteins, with 176 host genes being identified as interacting genes with all the viral proteins. Gene ontology and pathway analysis of these host proteins revealed their role in biological processes such as translation, mRNA splicing, and ribosomal pathways. We further identified EEF2, RPS3, RPL9, RPS16, and RPL11 as the top 5 most connected hub genes in the disease-causing network, with significant interactions among each other. These hub genes were found to be involved in ribosomal pathways and cytoplasmic translation. Further a disease-gene interaction was also prepared to investigate the role of hub genes in other disorders and to understand the condition of comorbidity in COVID-19 patients. We also identified 13 drug molecules having interactions with all the hub genes, and estradiol emerged as the top potential drug target for the COVID-19 patients. Our study provides valuable insights using the protein-protein interaction network of SARS-CoV-2 proteins with host proteins and highlights the molecular basis of manifestation of COVID-19 and proposes drug for repurposing.
As the pandemic continues to evolve, it is anticipated that investigating SARS-CoV-2 proteins will remain a critical area of focus for researchers globally, particularly in addressing potential challenges posed by specific SARS-CoV-2 variants in the future.

Few studies have addressed whether robotic-assisted total knee arthroplasty (RA-TKA) significantly impacts functional outcomes. This study was conducted to determine whether image-free RA-TKA ...improves function compared to conventional total knee arthroplasty (C-TKA), performed without the utilization of robotics or navigation, using the Minimal Clinically Important Difference (MCID) and Patient Acceptable Symptom State (PASS) as measures of meaningful clinical improvement.
A multicenter propensity score–matched retrospective study was conducted of RA-TKA using an image-free robotic system and C-TKA cases at an average follow-up of 14 months (range, 12 months to 20 months). Consecutive patients who underwent primary unilateral TKA and had a preoperative and postoperative Knee Injury and Osteoarthritis Outcome Score-Joint Replacement (KOOS-JR) were included. The primary outcomes were the MCID and PASS for KOOS-JR. 254 RA-TKA and 762 C-TKA patients were included, with no significant differences in sex, age, body mass index, or comorbidities.
Preoperative KOOS-JR scores were similar in the RA-TKA and C-TKA cohorts. Significantly greater improvement in KOOS-JR scores were achieved at 4 to 6 weeks postoperatively with RA-TKA compared to C-TKA. While the mean 1-year postoperative KOOS-JR was significantly higher in the RA-TKA cohort, no significant differences were found in the Delta KOOS-JR scores between the cohorts, when comparing preoperative and 1-year postoperative. No significant differences existed in the rates of MCID or PASS being achieved.
Image-free RA-TKA reduces pain and improves early functional recovery compared to C-TKA at 4 to 6 weeks, but functional outcomes at 1 year are equivalent based on the MCID and PASS for KOOS-JR.
The Coronavirus Disease 2019 (COVID-19) pandemic has caused a substantial number of patients to have their elective arthroplasty surgeries rescheduled. While it is established that patients with ...COVID-19 who are undergoing surgery have a significantly higher risk of experiencing postoperative complications and mortality, it is not well-known at what time after testing positive the risk of postoperative complications or mortality returns to normal.
PubMed (MEDLINE), Excerpta Medica dataBASE, and professional society websites were systematically reviewed on March 7, 2022 to identify studies and guidelines on the optimal timeframe to reschedule patients for elective surgery after preoperatively testing positive for COVID-19. Outcomes included postoperative complications such as mortality, pneumonia, acute respiratory distress syndrome, septic shock, and pulmonary embolism.
A total of 14 studies and professional society guidelines met the inclusion criteria for this systematic review. Patients with asymptomatic COVID-19 should be rescheduled 4-8 weeks after testing positive (as long as they do not develop symptoms in the interim), patients with mild/moderate COVID-19 should be rescheduled 6-8 weeks after testing positive (with complete resolution of symptoms), and patients with severe/critical COVID-19 should be rescheduled at a minimum of 12 weeks after hospital discharge (with complete resolution of symptoms).
Given the negative association between preoperative COVID-19 and postoperative complications, patients should have elective arthroplasty surgery rescheduled at differing timeframes based on their symptoms. In addition, a multidisciplinary and patient-centered approach to rescheduling patients is recommended. Further study is needed to examine the impact of novel COVID-19 variants and vaccination on timeframes for rescheduling surgery.
We previously showed that HIV-1 can alter the expression of tight junction proteins by downregulating Sonic hedgehog (Shh) signaling, thereby disrupting blood–brain barrier (BBB) integrity. In this ...study, we employed a conditional, CNS specific, Tat transgenic murine model to investigate if HIV-Tat exerts its neurotoxic effects by downregulating Shh signaling. Results indicate that Tat + mice exhibit significantly reduced expression of Shh and Gli1. HIV-Tat induced downregulation of Shh signaling correlated with disruption of BBB function and induced infiltration of peripheral leukocytes into the brain tissue. Further, our in vivo and in vitro experiments suggest that activation of Shh signaling can rescue detrimental effects of Tat on endothelial function by inducing the expression of junctional proteins and by decreasing the levels of inflammatory cytokines/chemokines.
