Changing operating room practices: the effect on postoperative endophthalmitis rates following cataract surgery.

PURPOSE: To determine whether four new operating room (OR) protocols instituted because of COVID-19 reduced the cataract surgical postoperative endophthalmitis rate (POE). DESIGN: Retrospective, sequential, clinical registry study. METHODS: 85 552 sequential patients undergoing cataract surgery at the Aravind Eye Hospitals between 1 January 2020 and 25 March 2020 (56 551 in group 1) and 3 May 2020 and 31 August 2020 (29 011 in group 2). In group 1, patients were not gowned, surgical gloves were disinfected but not changed between cases, OR floors were not cleaned between every case, and multiple patients underwent preparation and surgery in the same OR. In group 2, each patient was gowned, surgical gloves were changed between each case, OR floors and counters were cleaned between patients, and only one patient at a time underwent preparation and surgery in the OR. RESULTS: Group 1 was older, had slightly more females, and better preoperative vision. More eyes in group 2 underwent phacoemulsification (p=0.18). Three eyes (0.005%) in group 1 and 2 eyes (0.006%) in group 2 developed POE (p=0.77). Only one eye that underwent phacoemulsification developed POE; this was in group 1. There was no difference in posterior capsule rupture rate between the two groups. CONCLUSIONS: Adopting a set of four temporary OR protocols that are often mandatory in the Western world did not reduce the POE rate. Along with previously published studies, these results challenge the necessity of these common practices which may be needlessly costly and wasteful, arguing for the reevaluation of empiric and potentially unnecessary guidelines that govern ophthalmic surgeries.

The Effect of Language on Access to Timely COVID-19 Vaccination of Solid Abdominal Organ Transplant Recipients.

In dynamic healthcare environments including the COVID-19 pandemic, it is paramount to communicate health recommendations expediently and clearly. Research has shown social determinants of health affect the impact of COVID-19 on abdominal transplant recipients, but there has been less research on the effect of language proficiency. This is a cohort study of time to first COVID-19 vaccination among abdominal organ transplant recipients in an academic medical center in Boston, MA between 18 December 2020, and 15 February 2021. Cox proportional hazards analysis of time to vaccination by preferred language were adjusted for race, age group, insurance, and transplanted organ. Among 3001 patients, 53% were vaccinated during the study period. Language preference other than English was independently associated with delay to vaccination (0.64, p = 0.001), on adjusted analysis. In addition, Black, Hispanic and other race patients were less likely to be vaccinated than white patients (0.58, 0.67, 0.68 vs. reference, all p < 0.03). Language preference other than English is an independent barrier to solid abdominal organ transplant recipients' access to timely COVID-19 vaccination. Equity in care should be improved by providing targeted services to minority language speakers.

Trichosporon asahii opportunistic pneumonia after a severe COVID-19 infection.

This is the first reported case of fatal opportunistic Trichosporon asahii pneumonia in the setting of severe COVID-19 pneumonia. The patient had ventilator-requiring respiratory failure secondary to COVID-19 infection. The patient received intravenous broad-spectrum antibiotics, tocilizumab, and corticosteroids with subsequent development of cavitary infiltrates. Bronchoalveolar lavage grew T. asahii. We describe a rare complication of COVID-19 infection and describe the microbial diagnosis, possible mechanism of infection, and optimal treatment.

Antibiotic prophylaxis of postoperative endophthalmitis after cataract surgery: results of the 2021 ASCRS member survey.

In an online survey of >1200 global cataract surgeons, 66% were using intracameral (IC) antibiotic prophylaxis. This compared with 50% and 30% in the 2014 and 2007 surveys, respectively. Irrigation bottle infusion and intravitreal injection was each used by only 5% of respondents. For IC antibiotics, vancomycin was used by 6% in the United States (52% in 2014), compared with 83% for moxifloxacin (31% in 2014). Equal numbers used compounded moxifloxacin or the Vigamox bottle as the source. There was a decrease in respondents using preoperative (73% from 85%) and postoperative (86% from 97%) topical antibiotic prophylaxis; the latter was not used by 24% of surgeons injecting IC antibiotics. Reasons cited by those not using IC antibiotics include mixing/compounding risk (66%) and being unconvinced of the need (48%). However, 80% believe having a commercially approved IC antibiotic is important; if reasonably priced, this would increase adoption of IC prophylaxis to 93%.

HIV and SARS-CoV-2: Tracing a Path of Vaccine Research and Development.

PURPOSE OF REVIEW: This review examines the major advances and obstacles in the field of HIV vaccine research as they pertain to informing the development of vaccines against SARS-CoV-2. RECENT FINDINGS: Although the field of HIV research has yet to deliver a licensed vaccine, the technologies developed and knowledge gained in basic scientific disciplines, translational research, and community engagement have positively impacted the development of vaccines for other viruses, most notably and recently for SARS-CoV-2. These advances include the advent of viral vectors and mRNA as vaccine delivery platforms; the use of structural biology for immunogen design; an emergence of novel adjuvant formulations; a more sophisticated understanding of viral phylogenetics; improvements in the development and harmonization of accurate assays for vaccine immunogenicity; and maturation of the fields of bioethics and community engagement for clinical trials conducted in diverse populations. Decades of foundational research and investments into HIV biology, though yet to yield an authorized or approved vaccine for HIV/AIDS, have now paid dividends in the rapid development of safe and effective SARS-CoV-2 vaccines. This latter success presents an opportunity for feedback on improved pathways for development of safe and efficacious vaccines against HIV and other pathogens.

'It's always in the back of my mind': understanding the psychological impact of recovery following pancreaticoduodenectomy for cancer: a qualitative study.

OBJECTIVES: Ten per cent of patients diagnosed with pancreatic cancer undergo pancreaticoduodenectomy. There is limited previous research focusing on psychological well-being; unmet support needs impact negatively on quality of life. This paper reports the psychological impact of a pancreatic cancer diagnosis and subsequent pancreaticoduodenectomy, exploring how patients' lives alter following surgery and how they seek support. DESIGN: Inductive qualitative study involving in-depth semistructured interviews with 20 participants who had undergone pancreaticoduodenectomy for pancreatic or distal biliary duct cancer. Interviews were audiorecorded, transcribed and anonymised, and thematic analysis used principles of constant comparison. SETTING: Single National Health Service Trust in Northwest England. PARTICIPANTS: Patients were eligible for inclusion if they had had pancreaticoduodenectomy for head of pancreas cancer, periampullary cancer or distal cholangiocarcinoma between 6 months and 6 years previously, and had completed adjuvant chemotherapy. RESULTS: Analysis identified the following main themes: diagnosis and decision making around surgery; recovery from surgery and chemotherapy; burden of monitoring and ongoing symptoms; adjusting to 'a new normal'; understanding around prognosis; support-seeking. Participants seized the chance to have surgery, often without seeming to absorb the risks or their prognosis. They perceived that they were unable to control their life trajectory and, although they valued close monitoring, experienced anxiety around their appointments. Participants expressed uncertainty about whether they would be able to return to their former activities. There were tensions in their comments about support-seeking, but most felt that emotional support should be offered proactively. CONCLUSIONS: Patients should be made aware of potential psychological sequelae, and that treatment completion may trigger the need for more support. Clinical nurse specialists (CNSs) were identified as key members of the team in proactively offering support; further training for CNSs should be encouraged. Understanding patients' experience of living with cancer and the impact of treatment is crucial in enabling the development of improved support interventions.

The Risk of Postoperative Complications After Major Elective Surgery in Active or Resolved COVID-19 in the United States.

OBJECTIVE: To assess the association between the timing of surgery relative to the development of Covid-19 and the risks of postoperative complications. SUMMARY BACKGROUND DATA: It is unknown whether patients who recovered from Covid-19 and then underwent a major elective operation have an increased risk of developing postoperative complications. METHODS: The risk of postoperative complications for patients with Covid-19 undergoing 18 major types of elective operations in the Covid-19 Research Database was evaluated using multivariable logistic regression. Patients were grouped by time of surgery relative to SARS-CoV-2 infection; that is, surgery performed: (1) before January 1, 2020 ("pre-Covid-19"), (2) 0 to 4 weeks after SARS-CoV-2 infection ("peri-Covid-19"), (3) 4 to 8 weeks after infection ("early post-Covid-19"), and (4) ≥8 weeks after infection ("late post-Covid-19"). RESULTS: Of the 5479 patients who met study criteria, patients with peri-Covid-19 had an elevated risk of developing postoperative pneumonia [adjusted odds ratio (aOR), 6.46; 95% confidence interval (CI): 4.06-10.27], respiratory failure (aOR, 3.36; 95% CI: 2.22-5.10), pulmonary embolism (aOR, 2.73; 95% CI: 1.35-5.53), and sepsis (aOR, 3.67; 95% CI: 2.18-6.16) when compared to pre-Covid-19 patients. Early post-Covid-19 patients had an increased risk of developing postoperative pneumonia when compared to pre-Covid-19 patients (aOR, 2.44; 95% CI: 1.20-4.96). Late post-Covid-19 patients did not have an increased risk of postoperative complications when compared to pre-Covid-19 patients. CONCLUSIONS: Major, elective surgery 0 to 4 weeks after SARS-CoV-2 infection is associated with an increased risk of postoperative complications. Surgery performed 4 to 8 weeks after SARS-CoV-2 infection is still associated with an increased risk of postoperative pneumonia, whereas surgery 8 weeks after Covid-19 diagnosis is not associated with increased complications.

Plastic Surgery Away Rotations During the Coronavirus Disease Pandemic: A Virtual Experience.

BACKGROUND: Plastic surgery has traditionally been a specialty that places a strong emphasis on away rotations during the final year of medical school. These rotations allow the program and residency candidates to become better acquainted and are often crucial, as a large portion of applicants match at programs where they rotated. The coronavirus disease 2019 (COVID-19) pandemic forced many institutions to modify their educational curriculums when away rotations were canceled. We present our experience creating and implementing a virtual plastic surgery rotation. METHODS: Our virtual program was designed to mirror the in-person away rotations as much as possible. Prerotation and postrotation surveys from the students as well as feedback interviews with the students, residents, and faculty were used to gather information on the experience. RESULTS: We created a 2-week curriculum including approximately 20 hours of lecture time, 28 hours of operating room time, 2.5 hours of one-on-one mentorship, and 3 hours of social opportunities. Students reported that they learned more about plastic surgery and the residency program, but in contrast to this, some found it difficult to make an impression. CONCLUSIONS: We developed a novel 2-week virtual curriculum that provided visiting medical students from across the country an opportunity to learn more about plastic surgery and our residency program. Virtual learning is becoming a vital part of education, and our study provides pearls and pitfalls when structuring these experiences.

Safely Administering Potential QTc Prolonging Therapy Across a Large Health Care System in the COVID-19 Era.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARs-CoV-2) has resulted in a global pandemic. Hydroxychloroquine±azithromycin have been widely used to treat coronavirus disease 2019 (COVID-19) despite a paucity of evidence regarding efficacy. The incidence of torsade de pointes remains unknown. Widespread use of these medications forced overwhelmed health care systems to search for ways to effectively monitor these patients while simultaneously trying to minimize health care provider exposure and use of personal protective equipment. METHODS: Patients with COVID-19 positive who received hydroxychloroquine±azithromycin across 13 hospitals between March 1 and April 15 were included in this study. A comprehensive search of the electronic medical records was performed using a proprietary python script to identify any mention of QT prolongation, ventricular tachy-arrhythmias and cardiac arrest. RESULTS: The primary outcome of torsade de pointes was observed in 1 (0.015%) out of 6476 hospitalized patients with COVID-19 receiving hydroxychloroquine±azithromycin. Sixty-seven (1.03%) had hydroxychloroquine±azithromycin held or discontinued due to an average QT prolongation of 60.5±40.5 ms from a baseline QTc of 473.7±35.9 ms to a peak QTc of 532.6±31.6 ms. Of these patients, hydroxychloroquine±azithromycin were discontinued in 58 patients (86.6%), while one or more doses of therapy were held in the remaining nine (13.4%). A simplified approach to monitoring for QT prolongation and arrythmia was implemented on April 5. There were no deaths related to the medications with the simplified monitoring approach and health care provider exposure was reduced. CONCLUSIONS: The risk of torsade de pointes is low in hospitalized patients with COVID-19 receiving hydroxychloroquine±azithromycin therapy.

A low dose heparinized saline protocol is associated with improved duration of arterial line patency in critically ill COVID-19 patients.

PURPOSE: Critically ill patients with Coronavirus Disease 2019 (COVID-19) have high rates of line thrombosis. Our objective was to examine the safety and efficacy of a low dose heparinized saline (LDHS) arterial line (a-line) patency protocol in this population. MATERIALS AND METHODS: In this observational cohort study, patients ≥18 years with COVID-19 admitted to an ICU at one institution from March 20-May 25, 2020 were divided into two cohorts. Pre-LDHS patients had an episode of a-line thrombosis between March 20-April 19. Post-LDHS patients had an episode of a-line thrombosis between April 20-May 25 and received an LDHS solution (10 units/h) through their a-line pressure bag. RESULTS: Forty-one patients (pre-LDHS) and 30 patients (post-LDHS) were identified. Baseline characteristics were similar between groups, including age (61 versus 54 years; p = 0.24), median Sequential Organ Failure Assessment score (6 versus 7; p = 0.67) and systemic anticoagulation (47% versus 32%; p = 0.32). Median duration of a-line patency was significantly longer in post-LDHS versus pre-LDHS patients (8.5 versus 2.9 days; p < 0.001). The incidence of bleeding complications was similar between cohorts (13% vs. 10%; p = 0.71). CONCLUSIONS: A LDHS protocol was associated with a clinically significant improvement in a-line patency duration in COVID-19 patients, without increased bleeding risk.

Successful Treatment of Severe COVID-19 Pneumonia With Clazakizumab in a Heart Transplant Recipient: A Case Report.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is characterized by an overwhelming cytokine response. Various treatment strategies have been attempted. METHODS AND RESULTS: A 61-year-old man with heart transplantation in 2017 presented with fever, cough, and dyspnea, and was confirmed positive for coronavirus disease 2019 (COVID-19). Laboratory tests showed significant elevations in C-reactive protein and interleukin-6 (IL-6). Echocardiogram showed left ventricular ejection fraction 58% (with ejection fraction 57% 6 months prior). Given the lack of clear management guidelines, the patient was initially managed symptomatically. However, the patient subsequently had a rapid respiratory deterioration with worsening inflammatory markers on day 5 of admission. Tocilizumab (anti-IL-6R) was in low supply in the hospital. The patient was offered clazakizumab (anti-IL-6) for compassionate use. Patient received 25 mg intravenously × 1 dose. Within 24 hours, he showed significant improvement in symptoms, oxygen requirements, radiological findings, and inflammatory markers. There was a transient leukopenia that improved in 4 days. He was discharged home on day 11, with negative nasopharyngeal SARS-CoV-2 PCR as an outpatient on day 35, development of positive serum COVID-19 IgG antibody, and he continued to do well on day 60, with no heart-related symptoms. CONCLUSION: Clazakizumab is a monoclonal antibody against human IL-6, which may be helpful in inhibiting the cytokine response to SARS-CoV-2 in COVID-19. Although not yet FDA approved, it is being investigated for treatment of renal antibody-mediated rejection. Clinical trials of clazakizumab for treatment of COVID-19 are underway worldwide.

Evaluating the Effects of COVID-19 on Plastic Surgery Emergencies: Protocols and Analysis From a Level I Trauma Center.

BACKGROUND: The COVID-19 crisis has brought many unique challenges to the health care system. Across the United States, social distancing measures have been put in place, including stay-at-home (SAH) orders, to combat the spread of this infection. This has impacted the type and volume of traumatic injuries sustained during this time. Meanwhile, steps have been taken in our health care system to assure that adequate resources are available to maintain a high standard of patient care while recognizing the importance of protecting health care providers. Using comparative data, we aim to describe the trends in traumatic injuries managed by our plastic surgery service and detail the changes in consultation policies made to minimize provider exposure. METHODS: A retrospective chart review was performed of all plastic surgery emergencies at our institution during the 3 weeks preceding the issuance of SAH orders in Chicago and the 3 weeks after. The electronic medical record was queried for patient age, type and mechanism of injury, location where injury was sustained, presence of domestic violence, length of inpatient hospital stays, and treatment rendered. The two 3-week periods were then comparatively analyzed to determine differences and trends in these variables and treatment rendered. The 2 periods were then comparatively analyzed to determine differences and trends in these variables. RESULTS: There was a significant decrease in trauma consults since the issuance of SAH (88 pre-SAH vs 62 post-SAH) with a marked decrease in trauma-related hand injuries. There was an increase in the percentage of assault-related injuries including those associated with domestic violence, whereas there was an overall decrease in motor vehicle collisions. There was no notable change in the location where injuries were sustained. Significantly fewer patients were seen by house staff in the emergency room, whereas those requiring surgical intervention were able to receive care without delay. CONCLUSIONS: Stay-at-home orders in Chicago have impacted traumatic injury patterns seen by the Section of Plastic and Reconstructive Surgery at a level I Trauma Center. Safe and timely care can continue to be provided with thorough communication, vigilance, and guidance from our colleagues.

Effect of Chloroquine, Hydroxychloroquine, and Azithromycin on the Corrected QT Interval in Patients With SARS-CoV-2 Infection.

BACKGROUND: The novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is responsible for the global coronavirus disease 2019 pandemic. Small studies have shown a potential benefit of chloroquine/hydroxychloroquine±azithromycin for the treatment of coronavirus disease 2019. Use of these medications alone, or in combination, can lead to a prolongation of the QT interval, possibly increasing the risk of Torsade de pointes and sudden cardiac death. METHODS: Hospitalized patients treated with chloroquine/hydroxychloroquine±azithromycin from March 1 to the 23 at 3 hospitals within the Northwell Health system were included in this prospective, observational study. Serial assessments of the QT interval were performed. The primary outcome was QT prolongation resulting in Torsade de pointes. Secondary outcomes included QT prolongation, the need to prematurely discontinue any of the medications due to QT prolongation, and arrhythmogenic death. RESULTS: Two hundred one patients were treated for coronavirus disease 2019 with chloroquine/hydroxychloroquine. Ten patients (5.0%) received chloroquine, 191 (95.0%) received hydroxychloroquine, and 119 (59.2%) also received azithromycin. The primary outcome of torsade de pointes was not observed in the entire population. Baseline corrected QT interval intervals did not differ between patients treated with chloroquine/hydroxychloroquine (monotherapy group) versus those treated with combination group (chloroquine/hydroxychloroquine and azithromycin; 440.6±24.9 versus 439.9±24.7 ms, P=0.834). The maximum corrected QT interval during treatment was significantly longer in the combination group versus the monotherapy group (470.4±45.0 ms versus 453.3±37.0 ms, P=0.004). Seven patients (3.5%) required discontinuation of these medications due to corrected QT interval prolongation. No arrhythmogenic deaths were reported. CONCLUSIONS: In the largest reported cohort of coronavirus disease 2019 patients to date treated with chloroquine/hydroxychloroquine±azithromycin, no instances of Torsade de pointes, or arrhythmogenic death were reported. Although use of these medications resulted in QT prolongation, clinicians seldomly needed to discontinue therapy. Further study of the need for QT interval monitoring is needed before final recommendations can be made.
