INTRODUCTION
We describe the case of a postoperative fungal endophthalmitis caused by , an opportunistic yeast common in nature but rare as a causative agent in ocular infections. This would be the second reported case of endophthalmitis.
CASE REPORT
A patient came to our hospital with a dense hemovitreous caused by an inadvertent ocular perforation and retinal detachment during a cataract surgery. In the days following the first vitreoretinal surgery a chronic postoperative endophthalmitis was evidenced. Only after several surgeries as well as intravitreal antibiotics and sample takings, was detected. The treatment with oral voriconazole and an intraocular lens extraction controlled the infection.
DISCUSSION
, despite not being particularly aggressive in our case, was resistant to various consequent vitreoretinal surgeries. The unresponsiveness to treatment led us to contemplate the fungal etiology, and fortunately the cultures were positive for this yeast. In conjunction to antifungal therapy, it is possible that the IOL explantation played an important role in the treatment.
CONCLUSION
A high index of suspicion must be held in cases of fungal endophthalmitis. Both IOL explantation and oral antifungal therapy are useful treatment options in cases of endophthalmitis.

A Transcriptomic Approach to Understand Patient Susceptibility to Pneumonia After Abdominal Surgery.Annals of Surgery Mar 2024To describe immune pathways and gene networks altered following major abdominal surgery and to identify transcriptomic patterns associated with postoperative pneumonia.
OBJECTIVE
To describe immune pathways and gene networks altered following major abdominal surgery and to identify transcriptomic patterns associated with postoperative pneumonia.
BACKGROUND
Nosocomial infections are a major healthcare challenge, developing in over 20% of patients aged 45 or over undergoing major abdominal surgery, with postoperative pneumonia associated with an almost 5-fold increase in 30-day mortality.
METHODS
From a prospective consecutive cohort (n=150) undergoing major abdominal surgery, whole-blood RNA was collected preoperatively and at 3 time-points postoperatively (2-6, 24, and 48 h). Twelve patients diagnosed with postoperative pneumonia and 27 matched patients remaining infection-free were identified for analysis with RNA-sequencing.
RESULTS
Compared to preoperative sampling, 3639 genes were upregulated and 5043 downregulated at 2 to 6 hours. Pathway analysis demonstrated innate-immune activation with neutrophil degranulation and Toll-like-receptor signaling upregulation alongside adaptive-immune suppression. Cell-type deconvolution of preoperative RNA-sequencing revealed elevated S100A8/9-high neutrophils alongside reduced naïve CD4 T-cells in those later developing pneumonia. Preoperatively, a gene-signature characteristic of neutrophil degranulation was associated with postoperative pneumonia acquisition ( P =0.00092). A previously reported Sepsis Response Signature (SRSq) score, reflecting neutrophil dysfunction and a more dysregulated host response, at 48 hours postoperatively, differed between patients subsequently developing pneumonia and those remaining infection-free ( P =0.045). Analysis of the novel neutrophil gene-signature and SRSq scores in independent major abdominal surgery and polytrauma cohorts indicated good predictive performance in identifying patients suffering later infection.
CONCLUSIONS
Major abdominal surgery acutely upregulates innate-immune pathways while simultaneously suppressing adaptive-immune pathways. This is more prominent in patients developing postoperative pneumonia. Preoperative transcriptomic signatures characteristic of neutrophil degranulation and postoperative SRSq scores may be useful predictors of subsequent pneumonia risk.

Meta-Analysis
Efficacy and safety of broad spectrum penicillin with or without beta-lactamase inhibitors vs first and second generation cephalosporins as prophylactic antibiotics during cesarean section: a systematic review and meta-analysis.
This study assessed the efficacy and safety between broad spectrum penicillin (P2) with or without beta-lactamase inhibitors (P2+) versus first and second generation cephalosporins (C1&C2) in the prevention of post-cesarean infections. Relevant randomized controlled trials (RCTs) were searched in English and Chinese databases: nine RCTs were involved. Six trials compared P2+ vs C1&C2, no differences were found between interventions for endometritis, wound infection, urinary tract infection, febrile morbidity and maternal rashes. Four trials compared P2 vs C1&C2, no differences were found between interventions for endometritis, febrile morbidity, wound infection and urinary tract infection. Postoperative hospitalization was longer for women in P2 than C1&C2. Based on these results, P2/P2+ and C1&C2 may have similar efficacy on postoperative infections after cesarean section, there is no data on infant outcomes. CRD42022345721.

INTRODUCTION
Surgical site infection (SSI) is a widely seen postoperative complication that causes a decrease in life quality and an economic burden. In this study, we aim to find the predictive values of preoperative and postoperative neutrophile lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) values for SSI.
METHODS
In this retrospective study, 698 patients who had total abdominal hysterectomy operations with benign indications and confirmed histopathological results were accessed. In this study, the correlation of preoperative NLR, preoperative PLR, postoperative NLR, and postoperative PLR, with the occurrence of postoperative surgical site infection complications were examined.
RESULTS
The overall SSI rate was 9.46% (n = 66) with 30 days follow-up postoperatively. Preoperative NLR and PLR values of the patients who had SSIs were significantly lower than the control group (p 0.05). Postoperative NLR and PLR values of the patients who had SSIs were significantly higher than control group (p 0.05). In the patients who had postoperative SSIs, the increase of the values of postoperative NLR and PLR were significantly higher than the control group (p 0.05).
CONCLUSIONS
In our study, hematological markers of NLR and PLR were found to be independent and significant predictive markers for SSI.

Review
Preoperative preparation for cesarean delivery is a multistep approach for which protocols should exist at each hospital system. These protocols should be guided by the findings of this review. The interventions reviewed and recommendations made for this review have a common goal of decreasing maternal and neonatal morbidity and mortality related to cesarean delivery. The preoperative period starts before the patient's arrival to the hospital and ends immediately before skin incision. The Centers for Disease Control and Prevention recommends showering with either soap or an antiseptic solution at least the night before a procedure. Skin cleansing in addition to this has not been shown to further decrease rates of infection. Hair removal at the cesarean skin incision site is not necessary, but if preferred by the surgical team then clipping or depilatory creams should be used rather than shaving. Preoperative enema is not recommended. A clear liquid diet may be ingested up to 2 hours before and a light meal up to 6 hours before cesarean delivery. Consider giving a preoperative carbohydrate drink to nondiabetic patients up to 2 hours before planned cesarean delivery. Weight-based intravenous cefazolin is recommended 60 minutes before skin incision: 1-2 g intravenous for patients without obesity and 2 g for patients with obesity or weight ≥80 kg. Adjunctive azithromycin 500 mg intravenous is recommended for patients with labor or rupture of membranes. Preoperative gabapentin can be considered as a way to decrease pain scores with movement in the postoperative period. Tranexamic acid (1 g in 10-20 mL of saline or 10 mg/kg intravenous) is recommended prophylactically for patients at high risk of postpartum hemorrhage and can be considered in all patients. Routine use of mechanical venous thromboembolism prophylaxis is recommended preoperatively and is to be continued until the patient is ambulatory. Music and active warming of the patient, and adequate operating room temperature improves outcomes for the patient and neonate, respectively. Noise levels should allow clear communication between teams; however, a specific decibel level has not been defined in the data. Patient positioning with left lateral tilt decreases hypotensive episodes compared with right lateral tilt, which is not recommended. Manual displacers result in fewer hypotensive episodes than left lateral tilt. Both vaginal and skin preparation should be performed with either chlorhexidine (preferred) or povidone iodine. Placement of an indwelling urinary catheter is not necessary. Nonadhesive drapes are recommended. Cell salvage, although effective for high-risk patients, is not recommended for routine use. Maternal supplemental oxygen does not improve outcomes. A surgical safety checklist (including a timeout) is recommended for all cesarean deliveries.

Review
Lung transplantation can improve the survival of patients with severe chronic pulmonary disorders. However, the short- and long-term risk of infections can increase morbidity and mortality rates. A non-systematic review was performed to provide the most updated information on pathogen, host, and environment-related factors associated with the occurrence of bacterial, fungal, and viral infections as well as the most appropriate therapeutic options. Bacterial infections account for about 50% of all infectious diseases in lung transplanted patients, while viruses represent the second cause of infection accounting for one third of all infections. Almost 10% of patients develop invasive fungal infections during the first year after lung transplant. Pre-transplantation comorbidities, disruption of physical barriers during the surgery, and exposure to nosocomial pathogens during the hospital stay are directly associated with the occurrence of life-threatening infections. Empiric antimicrobial treatment after the assessment of individual risk factors, local epidemiology of drug-resistant pathogens and possible drug-drug interactions can improve the clinical outcomes.

Background Supracardiac total anomalous pulmonary communication (TAPVC) constitutes a rare congenital cardiac anomaly. Most babies with supracardiac TAPVC are diagnosed in infancy and undergo complete surgical repair during infancy. Delayed presentation of supracardiac TAPVC is rare, and the surgical outcomes are not well known. This retrospective study was conducted to determine the presentation and surgical outcome of supracardiac TAPVC among adolescents, which constitutes an extremely rare subgroup of TAPVC. Methodology This retrospective analysis was conducted among 15 adolescent patients with supracardiac TAPVC who underwent surgical repair in the cardiothoracic surgery department of a tertiary care center in India. This study aimed to assess the intraoperative, postoperative, immediate, early, and late outcomes of adolescent patients with supracardiac TAPVC who had undergone surgical repair between 2010 and 2014 in a tertiary care center in India. Results The study included 15 patients with a diagnosis of isolated supracardiac TAPVC. A mild degree of cyanosis was present in eight patients, recurrent episodes of lower respiratory tract infections were present in five patients, and dyspnea (New York Heart Association I/II) was noted in 12 patients. Mean oxygen saturation was 92% (range = 85-93%), and mean pulmonary artery pressure was 24 mmHg (range = 15-50 mmHg). After median stenotomy, a wide anastomosis was made between the common pulmonary venous chamber and the posterior wall of the left atrium. A fenestration was made in the Dacron patch in three patients who had raised pulmonary vascular resistance (PVR) preoperatively. Twelve patients were weaned off cardiopulmonary bypass (CPB) with minimal inotropic support. Three patients who had high preoperative PVR had difficulty in weaning from CPB. The mean CPB and cross-clamp time was 75 ± 12 minutes and 58 ± 9 minutes, respectively. Atrial fibrillation was noted in five (33.3%) patients in the early postoperative period, and three (20%) patients had pulmonary artery hypertensive crises postoperatively. There was no superficial or deep sternal wound infection in the postoperative period. Mild and moderate right ventricular dysfunction was present in four (26.67%) and two (13.3%) patients, respectively, in the postoperative period. On two-dimensional echocardiography during follow-up at the end of one year, there was no gradient across the anastomosis, and pulmonary artery pressure was normal in all patients. Conclusions Surgical repair of supracardiac TAPVC in adolescence has an excellent outcome. Survival of patients with supracardiac TAPVC until adolescence depends on the presence of a dilated vertical vein and a large atrial septal defect facilitating unobstructed pulmonary venous flow. The aim of the surgical repair should be to create a wide anastomosis between the left atrium and the pulmonary venous chamber which should be bigger than the size of the mitral valve orifice indexed to the body surface area as it would amount to no or negligible anastomotic gradient postoperatively.

Sepsis is a life-changing condition that can occur in patients undergoing cardiothoracic surgery. It is characterized by a dysregulated inflammatory response to infection, often leading to higher rates of organ dysfunction and mortality. The importance of early recognition and prompt intervention in managing sepsis-related complications in cardiothoracic surgery is pivotal to adequate surgical practice. Due to the multiple subsections that construct the broad spectrum of cardiothoracic surgery, it is important to address the presence of sepsis in elective cardiothoracic surgery, urgent/emergency cardiothoracic surgery, solid organ transplantation, and both temporary and permanent mechanical circulatory support (ie, left ventricular assist devices, extracorporeal membrane oxygenation, and percutaneous temporary devices [eg, Impella series]). Exploring the incidence, prevalence, and risk factors of said subsections can lead to improvement in postoperative outcomes. The impact of accompanying infections can progress into further operative morbidity and mortality. To this effect, the perioperative management of cardiothoracic surgery transcends surgical techniques and should undergo additional recognition of other occurrences such as wound infections, bloodstream infections, urinary tract infections, and pneumonia. Sepsis remains a concern in cardiothoracic surgery, as it can lead to devastating consequences. Hence, there is an evident need for heightened vigilance, early recognition, and effective management strategies to mitigate the risk of sepsis in this patient population. The purpose of this article is to provide an overview of sepsis in the different cardiothoracic surgery areas.

We aimed to evaluate the effect of the patient's clinical and paraclinical condition before and after surgery on short-term mortality and complication and long-term mortality. A retrospective cohort study was conducted and multivariate logistic regression was applied to determine the effect of demographic characteristics (sex, age, AO/OTA classification, height, weight, body mass index), medical history (hypertension, ischemic heart disease, diabetes mellitus, thyroid malfunction, cancer, osteoporosis, smoking) lab data (Complete blood cell, blood sugar, Blood Urea Nitrogen, Creatinine, Na, and K), surgery-related factors (Anesthesia time and type, implant, intraoperative blood transfusion, postoperative blood transfusion, and operation time), duration of admission to surgery and anticoagulant consumption on short-term mortality and complication and long-term mortality. Three hundred ten patients from November 2016 to September 2020 were diagnosed with an intertrochanteric fracture. 3.23% of patients died in hospital, 14.1% of patients confronted in-hospital complications, and 38.3% died after discharge till the study endpoint. ΔNumber of Neutrophiles is the primary determinant for in-hospital mortality in multivariate analysis. Age and blood transfusion are the main determinants of long-term mortality, and Na before surgery is the primary variable associated with postoperative complications. Among different analytical factors Na before surgery as a biomarker presenting dehydration was the main prognostic factor for in hospital complications. In hospital mortality was mainly because of infection and long-term mortality was associated with blood transfusion.

The British Journal of Ophthalmology Dec 2023To investigate the incidence of and risk factors for bleb-related infection (BRI) in patients who underwent mitomycin C-augmented primary trabeculectomy. (Review)
Review
BACKGROUND
To investigate the incidence of and risk factors for bleb-related infection (BRI) in patients who underwent mitomycin C-augmented primary trabeculectomy.
METHODS
We reviewed the medical charts of consecutive patients who had received primary trabeculectomy in Taipei Veterans General Hospital. We recorded the demographic and clinical characteristics of patients before, during and after surgery. Furthermore, we recorded the time interval between surgery and infection onset, clinical manifestations and visual outcomes of patients with BRI. The cumulative incidence of BRI was estimated using the Kaplan-Meier method. A Cox proportional hazards model was used to explore factors associated with BRI.
RESULTS
In total, 1663 eyes were postoperatively followed up for 94.57±65.23 months. The cumulative incidence of BRI was 1.86 per 1000 person-years during the 28-year follow-up period: 24 (1.44%) patients developed BRI and 6 (0.36%) patients additionally developed endophthalmitis. A multivariate analysis revealed a significant association of BRI with wound manipulation, high myopia and hyperlipidaemia. Patients younger than 60 years were more likely to receive wound manipulation than their elderly counterparts (<0.001). One year after BRI, the best corrected visual acuity of the eyes with blebitis did not change significantly, whereas that of the eyes with endophthalmitis worsened significantly.
CONCLUSION
Risk factors for BRI after trabeculectomy include wound manipulation, high myopia and hyperlipidaemia. Considering myopia is highly prevalent throughout the world and is a risk factor for glaucoma, the lifelong risk of BRI after trabeculectomy in eyes with high myopia warrants the attention of ophthalmologists.
