RESUMEN
BACKGROUND: Group B Streptococcus (GBS) infection remains a leading cause of newborn morbidity and mortality. The study aimed to determine the adherence rate to the universal screening policy a decade after its introduction. Secondly, whether the timing of antibiotics given in GBS carriers reduces the incidence of neonatal sepsis. METHODS: Delivery records at Hong Kong Baptist Hospital in 2022 were examined to retrieve antenatal and intrapartum details regarding maternal GBS carrier status, previous maternal GBS carrier status, antibiotic treatment, timing of treatment, neonatal condition at birth and whether the neonate had sepsis. Univariate statistics was used to assess the relationship between maternal GBS carrier and neonatal sepsis overall. Incidence of neonatal sepsis was stratified according to mode of delivery and timing of antibiotic. RESULTS: The adherence rate to the universal GBS screening policy was 97%. The risk of neonatal sepsis was 5.45 (95% CI 3.05 to 9.75) times higher in women who were GBS screened positive when compared to non-GBS carriers (p < 0.001). Amongst term neonates from GBS carriers delivered by Caesarean section, the risk of neonatal sepsis significantly decreased by 70% after antenatal antibiotic treatment (p = 0.041) whereas in term neonates delivered vaginally, the risk of neonatal sepsis decreased by 71% (p = 0.022) if intrapartum antibiotic prophylaxis was given 4 or more hours. CONCLUSION: Giving antenatal antibiotic treatment before Caesarean section or intrapartum antibiotic prophylaxis for 4 or more hours before vaginal delivery may decrease the risk of neonatal sepsis in term neonates delivered from GBS carriers.

¼ We aimed to determine the cost-effectiveness of different protocols of extended postoperative antibiotic prophylaxis (E-PAP) following adult spinal surgery.¼ Both stratified (randomized controlled trials only) and nonstratified (all studies) analyses demonstrated that E-PAP has no significant value in reducing the rate of surgical site infection (SSI), deep SSI, or superficial SSI.¼ Notably, the E-PAP protocols were associated with a significant increase in the length of hospital stay, resulting in an additional expenditure of $244.4 per episode for the E-PAP 72 hours protocol compared with PAP 24 hours and $309.8 per episode for the E-PAP >48 hours protocol compared with PAP <48 hours.¼ E-PAP does not demonstrate any significant reduction in the rate of SSIs following spine surgery. However, these extended protocols were significantly associated with an increase in the length of hospital stay and higher overall projected costs.

Perioperative antibiotic prophylaxis (PAP) in lung transplant recipients (LuTRs) has high heterogeneity between centers. Our aim was to investigate retrospectively the approach to PAP in our center over a 20-year period (2002-2023), and its impact on early post-operative infections (EPOIs) after lung transplantation (LuT). Primary endpoint was diagnosis of EPOI, defined as any bacterial infection including donor-derived events diagnosed within 30 days from LuT. Main exposure variables were type of PAP (combination vs. monotherapy) and PAP duration. We enrolled 111 LuTRs. PAP consisted of single-agent or combination regimens in 26 (25.2%) and 85 (74.8%) LuTR. Median PAP duration was 10 days (IQR 6-13) days. Piperacillin/tazobactam was the most common agent used either as monotherapy (n = 21, 80.7%) or as combination with levofloxacin (n = 79, 92.9%). EPOIs were diagnosed in 30 (27%) patients. At multivariable analysis no advantages were found for combination regimens compared to single-agent PAP in preventing EPOI (OR: 1.57, 95% CI: 0.488-5.068, p:0.448). The impact of PAP duration on EPOIs development was investigated including duration of PAP ≤6 days as main exposure variables, without finding a significantly impact (OR:2.165, 95% CI: 0.596-7.863, p: 0.240). Our results suggest no advantages for combination regimens PAP in preventing EPOI in LuTR.

BACKGROUND: Surgical site infections continue to be a significant challenge following colorectal surgery. These can result in extended hospital stays, hospital readmissions, increased treatment costs, and negative effects on patients' quality of life. Antibiotic prophylaxis plays a crucial role in preventing infection during surgery, specifically in preventing surgical site infections after colorectal surgery in adult patients. However, the optimal antibiotic regimen is still unclear based on current evidence. Considering the limitations of existing reviews, our goal is to conduct a comprehensive systematic review and network meta-analysis of randomized controlled trials to evaluate the comparative benefits and harms of available antibiotic prophylaxis regimens for preventing surgical site infections following colorectal surgery in adult patients. METHODS: We will search the Medline, EMBASE, CINAHL, Scopus, and Cochrane Central Register of Controlled Trials databases to identify relevant randomized controlled trials. We will include trials that (1) enrolled adults who underwent colorectal surgeries and (2) randomized them to any systemic administration of antibiotic (single or combined) prophylaxis before surgery compared to an alternative systemic antibiotic (single or combined antibiotic), placebo, control, or no prophylactic treatment. Pairs of reviewers will independently assess the risk of bias among eligible trials using a modified Cochrane risk of bias instrument for randomized trials. Our outcomes of interest include the rate of surgical site infection within 30 days of surgery, hospital length of stay, 30-day mortality, and treatment-related adverse effects. We will perform a contrast-based network meta-analysis using a frequentist random-effects model assuming a common heterogeneity parameter. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach will be utilized to assess the certainty of evidence for treatment effects. DISCUSSION: By synthesizing evidence from available RCTs, this study will provide valuable insight for clinicians, patients, and health policymakers on the most effective antibiotics for preventing surgical site infection.

Postpartum maternal sepsis is a leading cause of maternal mortality and morbidity. A single dose of prophylactic antibiotics following assisted vaginal births has been shown to significantly reduce postpartum maternal infection in a landmark multicentre randomised controlled trial, which led to its national recommendation. This project aimed to improve the local implementation of prophylactic antibiotics following assisted vaginal births to reduce postnatal maternal infections.Using a prospectively collated birth register, data were collected retrospectively on prophylactic antibiotics administration and postnatal maternal infection rates after assisted vaginal births at the Sandwell and West Birmingham Hospitals National Health Service Trust in North-West Birmingham of the UK. The data were collected from routinely used electronic health records over three audit cycles (n=287) between 2020 and 2023.A mixed-method approach was used to improve the use of prophylactic antibiotics: (1) evidence-based journal clubs targeting doctors in training, (2) presentations of results after all three audit cycles at our and (3) expedited a formal change of local guidelines to support prophylactic antibiotics use.Prophylactic antibiotic administration increased from 13.2% (December 2021) to 90.7% (July 2023), associated with a reduction in maternal infection rates (18.2% when prophylaxis was given vs 22.2% when no prophylaxis was given). However, we observed a gradual increase in the overall postnatal maternal infection rates during the project period.Our repeat audit identified prophylactic antibiotics were regularly omitted after deliveries in labour ward rooms (59.3%), compared with 100% of those achieved in theatre. After further interventions, prophylactic antibiotics administration rates were comparable between these clinical areas (>90%) in 2023.Together, we have demonstrated a simple set of interventions that induced sustainable changes in practice. Further evaluation of other modifiable risk factors and infection rates following all deliveries is warranted in view of the gradual increase in the overall postnatal maternal infection rates.

BACKGROUND: Group B Streptococcus (GBS) is a major cause of sepsis and meningitis in newborns. The Centers for Disease Control and Prevention (CDC) recommends to pregnant women, between 35 and 37 weeks of gestation, universal vaginal-rectal screening for GBS colonization, aimed at intrapartum antibiotic prophylaxis (IAP). The latter is the only currently available and highly effective method against early onset GBS neonatal infections. Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, the preventive measures implemented to mitigate the effects of SARS-CoV-2 infection led to the reduction in the access to many health facilities and services, including the obstetric and perinatal ones. The purpose of the present study was to evaluate the prevalence of maternal GBS colonization, as well as use of IAP and incidence of episodes of neonatal GBS infection when antibiotic prophylaxis has not been carried out in colonized and/or at risk subjects, in a population of pregnant women during (years 2020-2021) and after (year 2022) the COVID-19 pandemic, also with the aim to establish possible epidemiological and clinical differences in the two subjects' groups. METHODS: We retrospectively analyzed the clinical data of pregnant women admitted to, and delivering, at the Gynaecology and Obstetrics Unit, Department of Sciences for Health Promotion and Mother and Child Care, of the University Hospital of Palermo, Italy, from 01.01.2020 to 31.12.2022. For each of them, we recorded pertinent socio-demographic information, clinical data related to pregnancy, delivery and peripartum, and specifically execution and status of vaginal and rectal swab test for GBS detection, along with eventual administration and modality of IAP. The neonatal outcome was investigated in all cases at risk (positive maternal swabs status for GBS, either vaginal or rectal, with or without/incomplete IAP, preterm labor and/or delivery, premature rupture of membranes ≥ 18 h, previous pregnancy ended with neonatal early onset GBS disease [EOD], urine culture positive for GBS in any trimester of current gestation, intrapartum temperature ≥ 38 °C and/or any clinical/laboratory signs of suspected chorioamnionitis). The data concerning mothers and neonates at risk, observed during the pandemic (years 2020-2021), were compared with those of both subjects' groups with overlapping risk factors recorded in the following period (year 2022). The chi squared test has been applied in order to find out the relationship between pregnant women with GBS colonization receiving IAP and outcome of their neonates. RESULTS: The total source population of the study consisted of 2109 pregnant women, in addition to their 2144 newborns. Our analysis, however, focused on women and neonates with risk factors. The vaginal-rectal swab for GBS was performed in 1559 (73.92%) individuals. The test resulted positive in 178 cases overall (11.42% of those undergoing the screening). Amongst our whole sample of 2109 subjects, 298 women had an indication for IAP (vaginal and/or rectal GBS colonization, previous pregnancy ended with neonatal GBS EOD, urine culture positive for GBS in any trimester of current gestation, and unknown GBS status at labor onset with at least any among delivery at < 37 weeks' gestation, amniotic membranes rupture ≥ 18 h and/or intrapartum temperature ≥ 38.0 °C), and 64 (21.48%) received adequate treatment; for 23 (7.72%) it was inadequate/incomplete, while 211 (70.8%) did not receive IAP despite maternal GBS colonization and/or the presence of any of the above mentioned risk factors. Comparing the frequency of performing vaginal-rectal swabs in the women admitted in the two time periods, the quote of those screened out of the total in the pandemic period (years 2020-2021) was higher than that of those undergoing GBS screening out of the total admitted in the year 2022 (75.65% vs. 70.38%, p = 0.009), while a greater number (not statistically significant, p = 0.12) of adequate and complete IAP was conducted in 2022, than in the previous biennium (26.36 vs. 18.62%). During the whole 3 years study period, as expected, none of the newborns of mothers with GBS colonization and/or risk factors receiving IAP developed EOD. Conversely, 13 neonates with EOD, out of 179 (7.3%) born to mothers with risk factors, were observed: 3 among these patients' mothers performed incomplete IAP, while the other 10 did not receive IAP. Neither cases of neonatal meningitis, nor deaths were observed. The incidence rate in the full triennium under investigation, estimated as the ratio between the number of babies developing the disease out of the total of 2144 newborns, was 6.06; among those born to mothers with risk factors, if comparing the two time periods, the incidence was 8.06% in the pandemic biennium, while 5.45% in the following year, evidencing thus no statistical significance (p = 0.53). CONCLUSIONS: The present study revealed in our Department an increased prevalence of pregnant women screened for, and colonized by GBS, in the last decade. However, an overall still low frequency of vaginal-rectal swabs performed for GBS, and low number of adequate and complete IAP despite the presence of risk factors have been found, which did not notably change during the two time periods. Moreover, significant EOD incidence rates have been reported among children of mothers carrying risk factors, although also in this case no statistically significant differences have been observed during and after the pandemic. Such data seem to be in contrast to those reported during the COVID-19, showing a decrease in the access to health facilities and increased mortality/morbidity rates also due to the restrictive measures adopted to mitigate the effects of the pandemic. These findings might be explained by the presence within the same metropolitan area of our Department of a COVID hospital and birthing center, which all the patients with SARS-CoV-2 infection referred to, and likely leading to a weaker concern of getting sick perceived by our patients. Although IAP is an easy procedure to implement, however adherence and uniformity in the management protocols are still not optimal. Therefore, the prophylactic measures adopted to date cannot be considered fully satisfactory, and should be improved. Better skills integration and obstetrical-neonatological collaboration, in addition to new effective preventive tools, like vaccines able to prevent invasive disease, may allow further reduction in morbidity and mortality rates related to GBS perinatal infection.

PURPOSE OF REVIEW: Present an updated overview of the prevention, diagnosis, and management of infective endocarditis in adult patients with congenital heart disease. RECENT FINDINGS: Care for patients with infective endocarditis is changing in the areas of specialized teams, diagnostics, and prevention. Endocarditis teams should be involved in the care of ACHD patients. The 2023 Duke Criteria for Infective Endocarditis and the 2023 European Society of Cardiology Guidelines have updated the criteria for diagnosis including new major criteria such as CT and positron emission computed tomography with 18F-fluorodeoxyglucose (FDG) scans. Immunological, PCR, and nucleic acid-based tests are now acceptable means to isolate infective organisms. Clindamycin is no longer recommended for antibiotic prophylaxis due to resistance and side effect profile. Special considerations for antibiotic prophylaxis and management must be made for specific congenital heart diseases in adulthood and pregnant ACHD patients. Infective endocarditis (IE), a potentially devastating clinical entity, is a feared threat to the health of adults with congenital heart disease (ACHD). IE needs a systematic approach for its prevention, early diagnosis and management with a multidisciplinary IE team's involvement. There have been changes in the diagnostics and management of IE, which is reflected in updated diagnostic criteria. Timely blood cultures and imaging continue to be the mainstay of diagnosis, however the timing of blood cultures, microbiological testing, and types of diagnostic imaging such as the positron emission computed tomography with 18F-fluorodeoxyglucose (FDG) scan are new. Bicuspid aortic valves, ventricular septal defects, transcatheter pulmonary valve replacements, and tetralogy of Fallot are diagnoses at higher risk for IE in the ACHD population. The following article will focus on the preventive strategies, in addition to novel diagnostic and therapeutic approaches of IE in ACHD patients.

INTRODUCTION: There are some complications that can arise after surgery, like surgical site infection (SSI). In hernia repair, SSI incidence is low. Hence, the clinical practice guideline (CPG) published by the HerniaSurge Group (THG) does not recommend prophylactic antibiotics for hernia repair. Despite the unnecessary use of prophylactic antibiotics, regarding patient safety, prophylactic antibiotics can be used. However, each hospital has its own CPG and recommended antimicrobials based on the infection cases in its site. Regarding antimicrobial resistances, evaluating prophylactic antibiotics is essential to prevent increasing incidence of antimicrobial resistance cases. The aim of this study is to evaluate the use of prophylactic antibiotics in hernia inguinal cases. MATERIALS AND METHODS: This cross-sectional analytic study used patients' medical records between 2015 to 2020. Demographic data, surgery data and the used antimicrobial data were extracted and written in case report form. Identification of risk factors for inappropriate use of prophylactic antibiotics was done using logistic regression. RESULTS: We identified 55 inappropriate times of preoperative prophylactic antibiotic therapy cases out of 80 cases and 63 cases in post-operative antibiotics were different from the guideline. Statistical analysis did not find any factor related to inappropriate therapy time. CONCLUSION: The misuse of prophylactic antibiotics was frequently found regarding the duration of prophylactic antibiotics in both pre- and post-surgery setting. Nonetheless, no risk factor was identified with the inappropriate use of prophylactic antibiotics.

Importance: Prophylactic administration of antibiotics before skin incision is an important component in the prevention of periprosthetic joint infection in arthroplasty surgery. For antibiotics to be effective, the local tissue concentration (LTC) must exceed the minimum inhibitory concentration of typical infecting organisms; however, the LTC of cefazolin during arthroplasty is poorly understood. Objective: To compare the systemic concentration of cefazolin in serum with the LTC in fat, synovium, and bone during primary total knee arthroplasty (TKA) while assessing the effect of tourniquet inflation. Design, Setting, and Participants: This prospective randomized clinical trial was conducted from March 1, 2022, to June 30, 2023, in patients undergoing TKA at a single academic center. Intervention: Total knee arthroplasty with or without a limb tourniquet. Main Outcomes and Measures: Systemic blood and local tissues from the surgical site (fat, synovium, and bone) were harvested at regular intervals during the surgery. The primary outcome was the LTC of cefazolin, quantified using the liquid chromatography-tandem mass spectrometry technique. Results: A total of 59 patients were included in the study, with 29 in the tourniquet group (mean [SD] age, 69.3 [9.6] years; 23 [79.3%] female) and 30 in the no tourniquet group (mean [SD] age, 69.9 [9.7] years; 21 [70.0%] female). In patients undergoing TKA without a tourniquet, the mean concentration of cefazolin in serum was 71.9 µg/mL (95% CI, 66.4-77.5 µg/mL), whereas the mean LTCs were 13.9 µg/g (95% CI, 12.1-15.7 µg/g) in fat, 27.7 µg/g (95% CI, 24.3-31.0 µg/g) in synovium, and 17.7 µg/g (95% CI, 14.8-20.5 µg/g) in bone. For patients undergoing TKA with a tourniquet, the mean concentration of cefazolin in serum was 72.0 µg/mL (95% CI, 66.3-77.7 µg/mL), and the mean LTCs were 9.9 µg/g (95% CI, 8.7-11.1 µg/g) in fat, 21.8 µg/g (95% CI, 18.7-25.0 µg/g) in synovium, and 13.0 µg/g (95% CI, 10.8-15.2 µg/g) in bone. The use of a tourniquet resulted in significantly lower mean LTCs by 60 minutes after cefazolin infusion (10.8 µg/g [95% CI, 9.1-12.4 µg/g] vs 16.9 µg/g [95% CI, 14.1-19.6 µg/g], P = .001 in fat; 18.9 µg/g [95% CI, 14.1-23.6 µg/g] vs 25.8 µg/g [95% CI, 21.4-30.3 µg/g], P = .03 in synovium; and 11.8 µg/g [95% CI, 9.3-14.2 µg/g] vs 19.4 µg/g [95% CI, 14.5-24.4 µg/g], P = .007 in bone). Conclusions and Relevance: In this randomized clinical trial, the concentration of cefazolin was lower in local tissues (fat, synovium, and bone) than in systemic blood, and the use of a limb tourniquet further significantly reduced these concentrations. Although the current prophylactic dosing regimen for cefazolin provides sufficient serum concentrations, the levels in the periarticular tissue during TKA may be insufficient to prevent periprosthetic joint infection.

BACKGROUND: There is controversy regarding the maximum number of elements that can be included in a surgical site infection prevention bundle. In addition, it is unclear whether a bundle of this type can be implemented at a multicentre level. METHODS: A pragmatic, multicentre cohort study was designed to analyse surgical site infection rates in elective colorectal surgery after the sequential implementation of two preventive bundle protocols. Secondary outcomes were to determine compliance with individual measures and to establish their effectiveness, duration of stay, microbiology and 30-day mortality rate. RESULTS: A total of 32 205 patients were included. A 50% reduction in surgical site infection was achieved after the implementation of two sequential sets of bundles: from 18.16% in the Baseline group to 10.03% with Bundle-1 and 8.19% with Bundle-2. Bundle-2 reduced superficial-surgical site infection (OR 0.74 (95% c.i. 0.58 to 0.95); P = 0.018) and deep-surgical site infection (OR 0.66 (95% c.i. 0.46 to 0.93); P = 0.018) but not organ/space-surgical site infection (OR 0.88 (95% c.i. 0.74 to 1.06); P = 0.172). Compliance increased after the addition of four measures to Bundle-2. In the multivariable analysis, for organ/space-surgical site infection, laparoscopy, oral antibiotic prophylaxis and mechanical bowel preparation were protective factors in colonic procedures, while no protective factors were found in rectal surgery. Duration of stay fell significantly over time, from 7 in the Baseline group to 6 and 5 days for Bundle-1 and Bundle-2 respectively (P < 0.001). The mortality rate fell from 1.4% in the Baseline group to 0.59% and 0.6% for Bundle-1 and Bundle-2 respectively (P < 0.001). There was an increase in Gram-positive bacteria and yeast isolation, and reduction in Gram-negative bacteria and anaerobes in organ/space-surgical site infection. CONCLUSIONS: The addition of measures to create a final 10-measure protocol had a cumulative protective effect on reducing surgical site infection. However, organ/space-surgical site infection did not benefit from the addition. No protective measures were found for organ/space-surgical site infection in rectal surgery. Compliance with preventive measures increased from Bundle-1 to Bundle-2.

The objective of this study was to investigate the culture positivity and distribution of the conjunctival sac bacteria in the perioperative period of corneal refractive surgery. The selected time points of the perioperative period included before the use of antibiotic eye drops, before eye wash (after the use of antibiotic eye drops), after eye wash, and immediately after surgery. Conjunctival specimens obtained at the four time points were cultured to detect the positivity and distribution of bacteria. Before prophylactic antibiotic eye drops were administered, 49 eyes (50%) had positive bacterial culture results, with 45 isolates (91.8%) identified as Staphylococcus epidermidis. The culture positivity rates of the conjunctival sac specimens before eye wash, after eye wash, and immediately after surgery were 19.4%, 3.1%, and 4.1%, respectively. The difference was significant before and after the use of antibiotics and before and after eye wash (both P < 0.001). Staphylococcus epidermidis was the major pathogen in the conjunctival sac before corneal refractive surgery, and the culture positivity rate of the conjunctival bacteria was higher in males. Sixteen of 37 eyes (43.2%) with contact lenses had positive culture results, compared to 33 of 61 eyes (54.1%) without contact lenses (P > 0.05). The judicious preoperative use of antibiotic eye drops combined with the surgical sterile eye wash procedure maximised the removal of conjunctival sac bacteria. Skilled surgical manipulations generally did not increase the risk of infection.

BACKGROUND: Having knowledge of the dental procedures that necessitate endocarditis prophylaxis is of high importance. Therefore, the aim of the present study was to determine the knowledge level and attitudes of general medical and dental practitioners, dental specialists, and cardiologists in Tehran and Hamadan about endocarditis. METHODS: This cross-sectional study was carried out on 420 general medical and dental practitioners, dental specialists, and cardiologists in Tehran and Hamadan provinces in 2015. The questionnaire used in this research consisted of three parts as follows: part one: information on cardiac diseases; part two: dental procedures requiring endocarditis prophylaxis; part three: antibiotic diet in endocarditis prophylaxis. Independent t-test, one-way ANOVA, and chi-square tests were conducted to analyze the data. All the analyses were performed in SPSS version 16. RESULTS: The results showed that 86.7 had a relatively favorable and 10.5% of subjects had a favorable level of knowledge about endocarditis. Also, 58.6% of subjects had a poor attitude toward endocarditis prophylaxis. There was a significant relationship between knowledge and attitude, age, gender, and work experience (P < 0.001). There was a significant relationship between knowledge and attitude, and job groups; dental specialists had a more favorable knowledge and positive attitude than others (P < 0.001). CONCLUSION: We recommended developing more practical training programs in dental schools on cardiac diseases, and dental procedures requiring endocarditis prophylaxis and antibiotic diets.

PURPOSE: Pneumocystis jirovecii pneumonia (PJP) prophylaxis is required by provincial and national drug monographs during glioma treatment using temozolomide (TMZ) concurrently with radiation (TMZ-RT). However, real-world data suggest the potential benefits of PJP prophylaxis may not outweigh its potential harms in this population. METHODS: We conducted a single-center patient survey and a national physician survey to explore the role of PJP prophylaxis amongst glioma patients undergoing TMZ-RT. RESULTS: 23% (31/133) of physicians and 60% (44/73) of patients completed a survey. The median patient age was 42 (range 20-77); 85% (34/40) had completed adjuvant TMZ. Although only 2.4% (1/41) of patients received PJP prophylaxis, only one person (without PJP prophylaxis) was hospitalized for pneumonia. When presented with hypothetical PJP risks, 13.2% (5/38) of patients were concerned about PJP infection, while 26% (10/38) were concerned about potential side effects from prophylactic antibiotics. Most physicians (77%, 17/22) perceived the evidence for PJP prophylaxis as weak; 58% (11/19) did not routinely prescribe prophylaxis, and 73% (16/22) felt that PJP prophylaxis should be limited to patients with additional risk factors. Over 95% of physicians estimated that the incidence of PJP was < 1% in their last 5 years of practice regardless of PJP prophylaxis. For 73% (16/22) of physicians, to prescribe PJP prophylaxis, the risk of PJP infection needed to be 3-8%. CONCLUSION: The current recommendation to routinely prescribe PJP prophylaxis in patients receiving TMZ-RT in the absence of other risk factors warrants reconsideration.

BACKGROUND: Postoperative infection after the Latarjet procedure, ranging from 1% to 6%, can compromise the functional outcome of young athletes. Cutibacterium acnes is a main pathogen as a consequence of an intraoperative contamination. PURPOSE: To evaluate intraoperative contamination with C. acnes and the effectiveness of the local application of vancomycin during the Latarjet procedure. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: This was a single-center study including 75 patients (mean age, 26 years; range, 15-55 years) operated on for anterior shoulder instability with the primary open Latarjet procedure; they underwent the same protocol of skin preparation and preoperative prophylactic antibiotics. Three groups of 25 patients were created and divided sequentially, without the results of each group being known before the end of the study: group A (5 mg/mL of vancomycin), group B (20 mg/mL of vancomycin), and group C (control group with no vancomycin). Swab samples of the coracoid were taken before sectioning the coracoid process (time 1) and after its preparation (time 2). The coracoid was then wrapped in gauze impregnated with different concentrations of vancomycin, except for group C. A final sample (time 3) was taken before screwing the bone block onto the glenoid. All samples were cultured for 21 days, and patients underwent clinical and radiological follow-up for 6 months. RESULTS: The C. acnes contamination rates at times 1, 2, and 3 were 25%, 44%, and 45%, respectively, without significant difference. There was no significant difference between groups A and B with respect to the number of positive cultures at each time point. Of 9 positive cultures at time 1, all were still positive at time 3 in group A, whereas 3 of 5 were negative in group B (P = .027). The rate of C. acnes at time 3 in the control group was higher than that in the 2 other groups (68% vs 44% for group A and 20% for group B; P = .003). Body mass index was the only prognostic factor for a C. acnes-positive culture (26.05 ± 3.39 vs 23.34 ± 2.33; P = .018). No clinical infection was reported at the 6-month postoperative follow-up. CONCLUSION: The rate of C. acnes contamination ranged from 25% to 68% during the open Latarjet procedure in young athletes. Vancomycin reduced the bacterial contamination when it was used at high concentrations in a gauze wrap on the coracoid. The type of C. acnes detected and its clinical implications remain to be studied.

BACKGROUND: Autologous fat transfer (AFT) is increasingly adopted as another total breast reconstruction option. The aim of this study was to investigate the efficacy of prolonged antibiotic treatment on the onset of surgical site infections (SSIs) in patients treated with AFT for total breast reconstruction. METHODS: This retrospective cohort study was conducted on patients who received AFT for total breast reconstruction, with antibiotic prophylaxis during their (multiple) AFT procedure(s) from 9 December 2020 to 10 October 2023. Patients were divided into 2 groups according to their prophylactic antibiotic regimen. The primary outcome was analyzed, including the cumulative incidence, the relative risk (RR), the absolute risk reduction (ARR), and the number needed to treat (NNT). For the secondary outcome, a multilevel logistic regression analysis was performed. RESULTS: Seven hundred sixty-five surgeries in 205 patients were analyzed. Six hundred twenty-four surgeries on 168 patients had perioperative antibiotic prophylaxis in combination with postoperative antibiotic prophylaxis administered (group 1). One hundred forty-one surgeries on 37 patients had only perioperative antibiotic prophylaxis administered (group 2). The RR was 0.68 (95% confidence interval [CI]; 0.14-3.31) of a SSI when receiving peri- and postoperative antibiotic prophylaxis in comparison with treatment with only perioperative prophylaxis. The ARR was 0.46% (95% CI; -1.40 to 2.32) with a NNT of 219 patients. CONCLUSION: Prolonged antibiotic prophylaxis is ineffective for patients who receive total breast reconstruction with AFT. This study showed no statistically significant difference in SSIs of the reconstructed breast after receiving prolonged antibiotic treatment in comparison with single-shot perioperative antibiotic prophylaxis.

BACKGROUND: The ideal duration of neonatal antibiotic prophylaxis is not determined with wide variance in practice. This study aims to evaluate the association between duration of antibiotics and surgical site infection (SSI) in neonatal surgery. METHODS: A retrospective review regarding antibiotic prophylaxis was performed on <30-day-old surgical patients at a children's hospital from 2014 to 2019. The patients were analyzed based on demographics, presence of SSI, and antibiotic duration. The primary outcome was the development of SSI with ANOVA, chi-square, and recursive partitioning used for statistical analysis. RESULTS: 19/155 patients developed an SSI (12.26 â%). Those with an SSI had a lower weight at surgery (p â= â0.03). Additionally, wound classification (p â= â0.17) and antibiotic duration >48hrs (p â= â0.94) made no statistical difference in SSI rate. The two variables most closely linked to SSI development were gestational age (100 â%) and weight at time of procedure (80.76 â%). CONCLUSIONS: Antibiotic prophylaxis >48 âh did not decrease the incidence of SSI. Risk factors for SSI development in neonatal surgery were lower gestational age, decreased weight at time of procedure and total length of procedure.

BACKGROUND & AIMS: The benefits of prophylactic antibiotics in patients with alcohol-associated hepatitis (AH) receiving steroids remain unclear. We aimed to assess the clinical impact of prophylactic antibiotics in AH patients receiving steroids. METHODS: We systematically reviewed four electronic databases from inception to 30 November 2023. Pooled estimates were analysed using random-effects models. The primary outcome was 90-day survival. Secondary outcomes included infection at days 30 and 90 days, hepatorenal syndrome (HRS), acute kidney injury (AKI), hepatic encephalopathy (HE) and drug-related adverse events (AE). Trial sequential analyses were performed for the primary outcome of 90-day mortality. RESULTS: We screened 419 articles and included six eligible studies (four RCTs and two matched cohort studies) with a total of 510 patients. Compared to standard medical treatment (SMT), prophylactic antibiotics were associated with a lower risk of infection at 30 days (OR: 0.35, 95%CI: 0.20-0.59, I 2 = 0%), infection at 90 days (OR: 0.26, 95%CI: 0.10-0.67, I 2 = 0%) and a lower rate of HE (OR: 0.32, 95%CI: 0.12-0.87, I 2 = 0%). However, prophylactic antibiotics did not improve 90-day survival, sepsis-related mortality, HRS, or AKI. The risks of drug-related AE and fungal infections were similar in patients with AH who received prophylactic antibiotics or SMT. Using trial sequential analysis, the minimum sample size required to detect a 15% relative risk reduction in 90 days mortality with prophylactic antibiotics was 1171. CONCLUSIONS: In hospitalized AH patients receiving steroid therapy, prophylactic antibiotics reduced the risk of infection and HE, but did not improve survival or prevent AKI compared to SMT.

Surgical site infection is a common complication following pancreaticoduodenectomy and is a major source of postoperative morbidity. Surgical site infection is more common among patients who undergo preoperative biliary instrumentation, likely because of the introduction of intestinal flora into the normally sterile biliary tree. Frequently, bacterial isolates from surgical site infections after pancreaticoduodenectomy demonstrate resistance to the antibiotic agents typically used for surgical prophylaxis, suggesting that broad-spectrum coverage may be beneficial. This chapter summarizes the current evidence regarding surgical site infection following pancreatic surgery and describes the rationale and methodology underlying a multicenter randomized trial evaluating piperacillin-tazobactam compared with cefoxitin for surgical site infection prevention following pancreaticoduodenectomy. As the first U.S. randomized surgical trial to utilize a clinical registry for data collection, this study serves as proof of concept for registry-based clinical trials. The trial has successfully completed patient accrual, and study results are forthcoming.
