Epidemiologic Characterization and Risk Factors for Congenital Syphilis in Northeast Mexico: A Case-control Study 2016–2024

Background: Congenital syphilis (CS) is an infectious disease caused by Treponema pallidum, which is transmitted through the placenta during pregnancy. Since 2001, a notable and consistent rise in the prevalence of CS cases has been observed, especially in low- and middle-income countries. Currently, information regarding the risk factors for this phenomenon has been scarcely addressed. Methods: A case-control study was conducted to analyze the risk factors for CS. Cases of CS were defined according to scenarios 1 and 2 from Centers for Disease Control criteria, while controls were considered those from scenarios 3 and 4. Data were collected from clinical records from 2016 to 2024 from a hospital in the metropolitan area of Monterrey, Mexico. Statistical analysis was conducted through SPSS V.22. Results: In total 297 syphilis-infected mothers were included in the analyses. Multivariable logistic regression analysis showed that CS was related to late maternal diagnosis, especially after birth [OR: 4.352 (1.313–14.423)]. Additionally, women with a high nontreponemal serum test titer (≥1:8) had an increased risk of delivering an infant with CS [OR: 4.380 (1.946-9.856)]. Infants born to mothers receiving adequate treatment [OR: 0.213 (0.101-0.450)] were a protective factor. Conclusion: CS is a major public health worldwide. Adequate treatment is critical for the prevention of CS. Strategies focusing on prenatal care, early diagnosis, and adequate treatment among those with high nontreponemal titer should be strengthened to prevent CS.

High fibrinogen-prealbumin ratio (FPR) predicts stroke-associated pneumonia

ObjectivesAlthough numerous factors had been found to be associated with stroke-associated pneumonia (SAP), the underlying mechanisms of SAP remain unclear. Fibrinogen-prealbumin ratio (FPR) is a novel indicator that could balance the effects of inflammation and nutrition, which might reflect biological status of patients more comprehensively than other biomarkers. To date, FPR has not been explored in acute ischemic stroke patients. This study aims to explore the relationship between FPR and SAP. Materials and methods900 stroke patients participated in this retrospective study and 146 healthy controls were recruited. Fibrinogen and prealbumin were measured within 24 hours on admission. FPR was calculated after dividing fibrinogen (g/L) by prealbumin (mg/L) × 1000. SAP was defined according to the modified Centers for Disease Control criteria. Results121 patients were diagnosed with SAP. Log10FPR was higher in stroke patients than healthy controls. In logistic regression analysis, log10FPR was independently associated with SAP (OR 15.568; 95% CI: 3.287-73.732; P=0.001). Moreover, after using ROC curve, the predictive power of “current standard”(defined as A2DS2 plus leukocyte count and log10hs-CRP) plus log10FPR (0.832[0.804-0.857]) was higher than “current standard” (0.811[0.782-0.837], P=0.0944) and A2DS2 plus log10FPR (0.801[0.772-0.828], P=0.0316). No significant difference was found between the predictive power of A2DS2 plus log10FPR and “current standard” (P =0.6342). ConclusionHigher FPR was observed in stroke patients compared with healthy controls and was significantly associated with SAP. FPR might provide useful clues for timely identification and treatment of SAP.

Accuracy of the Wound Healing Questionnaire in the diagnosis of surgical-site infection after abdominal surgery in low- and middle-income countries.

Telemedicine is being adopted for postoperative surveillance but requires evaluation for efficacy. This study tested a telephone Wound Healing Questionnaire (WHQ) to diagnose surgical site infection (SSI) after abdominal surgery in low- and middle-income countries. A multi-centre, international, prospective study was embedded in the FALCON trial; a factorial RCT testing measures to reduce SSI in seven low- and middle-income countries (NCT03700749). It was conducted according to a pre-registered protocol (SWAT126) and reported according to STARD guidelines. The reference test was in-person review by a trained clinician at 30 postoperative days according to US Centres for Disease Control criteria. The index test was telephone administration of an adapted WHQ at 27 to 30 postoperative days by a researcher blinded to the outcome of in-person review. The sum of item response scores generated an overall score between 0 and 29. The primary outcome was the diagnostic accuracy of the WHQ, defined as the proportion of SSI correctly identified by the telephone WHQ, and summarized using the area under the receiving operator characteristic curve (AUROC) and diagnostic test accuracy statistics. Patients were included from three upper-middle income (396 patients, 13 hospitals), three lower-middle income (746 patients, 19 hospitals), and one low-income country (54 patients, 4 hospitals). 90.3% (1088 of 1196) patients were successfully contacted. Those with non-midline incisions (adjusted odds ratio: 0.36, 95% c.i. 0.17 to 0.73, P=0.005) or a confirmed diagnosis of SSI on in-person assessment (odds ratio: 0.42, 95% c.i. 0.20 to 0.92, P=0.006) were harder to reach. The questionnaire correctly discriminated between most patients with and without SSI (AUROC 0.869, 95% c.i. 0.824 to 0.914), which was consistent across subgroups. A representative cut-off score of ≥4 displayed a sensitivity of 0.701 (0.610-0.792), specificity of 0.911 (0.878-0.943), positive predictive value of 0.723 (0.633-0.814) and negative predictive value of 0.901 (0.867-0.935). SSI can be diagnosed using a telephone questionnaire (obviating in-person assessment) in low resource settings.

Evaluation of surveillance system and response for maternal and perinatal mortalities in Meda Welabu District, Ethiopia, 2023.

The weekly disease surveillance system (WDSS) serves as a precursor to possible public health emergencies. The Meda Welabu Woreda Bale Zone in Ethiopia has reporting rates of 87% overall timeliness and 88% completeness in 2023, falling short of the 100% objective. Low reporting rates could mean that epidemics in the province are only discovered later. In the Meda Welabu Woreda Bale Zone of Ethiopia, the study was carried out to assess the WDSS maternal and perinatal death surveillance response (MPDSR). Using the most recent Centers for Disease Control (CDC) criteria for assessing public health monitoring systems, we carried out a descriptive cross-sectional analysis. Data from the health workers were gathered through key informant interviews and questionnaires given by the interviewer. Using checklists, the availability of resources was evaluated. Twenty-two health personnel and twelve Health Extension Workers were questioned; of them, 15 (44%) were females. Nurses made up 18 (53%) of the health personnel. Only sixteen (47%) of the respondents were aware of the WDSS goals, compared to thirty-four (53%) who were aware of the deadlines for submitting data to the next level. A total of eight (24%) responders received training in using the WDSS. 26(76%) respondents said they would be willing to continue participating in the WDSS, whereas 6 (18%) respondents said they had analyzed the data from the WDSS. Of the health facilities, seven (50%) reported having issues with the district public health emergency officer. However, low attention to immediately report on maternal and perinatal death (42.9%). It was concluded that the WDSS was adaptable, reasonable, and easy to use. That was erratic and premature, though. We suggest that healthcare professionals in the province receive training on maternal and perinatal death surveillance response. In Meda Welabu Woreda Bale Zone conducted an evaluation in 2023 of the weekly disease surveillance system, maternal and perinatal death surveillance response. Launched in 1998, the system tracks weekly trends of diseases under surveillance to provide an early warning of any dangers to public health, but maternal and perinatal death surveillance were included on 2013. On the other hand, in 2023, the overall completion and timeliness of reports was 88%, falling short of the 100% aim. Low rates of reporting could mean that outbreaks and quality of service in the province were discovered later than expected. Using current centers for disease control criteria and interviewer-administered data, a descriptive cross-sectional study was undertaken.

A Study of Clinical Profile, Radiological and Electroencephalographic Characteristics of Sporadic Creutzfeldt-Jakob Disease From a Tertiary Care Hospital.

Background Sporadic Creutzfeldt-Jakob disease (CJD), the most common form of human prion disease, is the archetypal diagnosis in this category. However, the spectrum of possible diagnoses is wide, encompassing various treatable conditions. A lack of standardized diagnostic criteria and a tendency to opt for brain biopsies and clinical autopsies can be limiting factors in reaching a conclusive diagnosis. Objective This study aims to retrospectively analyze clinical and investigative findings in patients referred to a specialized neurology clinic exhibiting rapidly progressive dementia. These patients were ultimately diagnosed with Probable sporadic Creutzfeldt-Jakob disease (CJD) based on the 2018 CDC criteria for sporadic CJD. Materials and Methods This study included cases of CJD diagnosed based on clinical, electrophysiological, and imaging parameters at a tertiary care hospital in India from 2016 to 2020. The diagnostic criteria proposed by the CDC (Centers for Disease Control and Prevention) were employed to categorize patients as definite, probable, or possible CJD cases. All patients underwent MRI (magnetic resonance imaging) imaging and EEG ( electroencephalography) recording, while diagnostic brain biopsies were not conducted due to a lack of consent from close relatives. Results This observational descriptive study comprised four patients diagnosed with Probable sporadic CJD (sCJD), all of whom were female. The patients exhibited an age range of 57 to 75 years at the onset of the disease, with a mean age of onset at 67.5 years. Unfortunately, all patients succumbed to the disease within 6 months of its onset. Rapidly progressive dementia was a common symptom in all cases. Additionally, patient one and patient four displayed myoclonus and dystonia, patient two exhibited myoclonus and akinetic mutism, and patient three had myoclonus, chorea, and ataxia. MR brain imaging, including T2 sequence, FLAIR sequence, and DWI/ADC mapping, was performed on all patients, revealing both cortical gray matter and deep gray matter (basal ganglia) T2/FLAIR hyperintensities with DWI restriction. A cortical ribboning pattern was observed in all cases. EEG results indicated generalized delta slow waves with triphasic complexes in three patients, while patient three alone displayed periodic sharp wave complexes at a frequency of 1 per 1 - 1.5 seconds. Conclusion MRI with DWI and ADC brain mapping emerges as the most valuable diagnostic tool for patients with clinical presentations suggesting sCJD. In this study, all patients displayed restricted diffusion, as confirmed by ADC mapping. Regrettably, the characteristic features of sCJD with restricted diffusion in the cortex, thalamus, and basal ganglia may often elude detection by radiologists outside specialized centers, resulting in diagnostic delays. Conversely, when basal ganglia or cortical signal abnormalities are detected in conjunction with parenchymal swelling, alternative diagnoses such as encephalitis or lymphoma should be considered, as parenchymal swelling is not a typical feature of sCJD as revealed by MRI.

OGC P61 Audit of diagnosis and treatment of early pneumonia after elective oesophagogastric resections

Abstract Background Respiratory complications after oesophagogastric (OG) cancer surgery are common and present as some of the most severe. Post-operative respiratory complications reduce disease free and overall survival. Incorrect use of antibiotics can have negative outcomes. Are the diagnosis criteria clear and do such patients receive the correct management? This audit assesses diagnoses of pneumonia against the US Centers for Disease Control (CDC) criteria and antibiotic choice against National Institute for Health and Care Excellence (NICE) guidelines in a regional OG cancer surgery centre (which may be replicated in many other OG centres). Methods We examined records of 109 patients who underwent elective OG surgery at University College Hospital London between July 2021 and June 2022. The post-operative period was defined as 7 days from the initial operation. Results 30.2% of all patients were treated with antibiotics for pneumonia in the post-operative period. 42.4% of these patients had a sputum sample taken at the time of clinical suspicion of pneumonia, and 42.8% of these grew one or more relevant organisms. 69.7% of treated patients were prescribed a NICE-approved antibiotic. 17.4% of all patients developed pneumonia per the US CDC criteria and these patients had a longer stay in ICU (10.6 days compared to 5.3 days) and hospital (29.4 days compared to 14.3 days) than those who did not. 30-day mortality rate was 0% in this group. Conclusions This audit identified variability in diagnosis and antibiotic prescribing in post-operative pneumoniae. Sputum analysis was used inconsistently to diagnose and guide antibiotic therapies; cultures were often taken after antimicrobials were initiated, with patients treated symptomatically rather than based on microbiology results. Recommendations following this audit comprised; the use of CDC criteria to promote accurate diagnosis in the post-operative period, and regular multidisciplinary review of antibiotic agents prescribed to ensure appropriate targeted treatment.

Predictors of Preexposure Prophylaxis Eligibility among Pregnant People with Opioid Use Disorder.

We seek to evaluate risk factors for eligibility for preexposure prophylaxis (PrEP) among pregnant people with opioid use disorder (OUD). This is a single-site retrospective cohort study of pregnant people admitted for management of OUD at an urban, tertiary care center from 2013 to 2022. PrEP eligibility was defined based on (1) modified American College of Obstetricians and Gynecologists' (ACOG) 2014 criteria: diagnosis of a sexually transmitted infection (STI), engagement in transactional sex work, intravenous drug use (IVDU), or incarceration and (2) modified 2021 Centers for Disease Control (CDC) criteria: diagnosis of bacterial STI (e.g., gonorrhea or syphilis) or transactional sex work. Risk factors associated with PrEP eligibility were evaluated using chi- square or Fischer's exact tests for categorical variables and t-tests or Wilcoxon rank-sum tests for continuous variables. Multivariable regression was used to control for confounding covariates, defined as p < 0.10 on bivariate analysis. p < 0.05 was used to indicate statistical significance. A total of 132 individuals met inclusion criteria, of whom 101 (76.5%) were deemed eligible for PrEP by meeting one or more modified 2014 ACOG criteria: 42 (31.8%) were incarcerated or had one or more STIs, while 30 (22.7%) endorsed engaging in transactional sex work and 68 (58.6%) endorsed IVDU. Using modified 2021 CDC criteria, 37 (28%) met PrEP eligibility, with 12 (9.1%) diagnosed specifically with a bacterial STI and 30 (22.7%) engaging in transactional sex work. Only comorbid psychiatric illness was associated with an increased risk for PrEP eligibility based on 2014 criteria, which persisted after controlling for maternal race/ethnicity (aRR 1.52, 95% confidence interval [CI] 1.24-1.86), and 2021 criteria, which persisted after controlling for nulliparity (aRR 2.12, 95% CI 1.30-3.57). A significant number of pregnant people with OUD meet one or more criteria for PrEP, with comorbid psychiatric conditions increasing the risk of meeting criteria. · Comorbid psychiatric illness is significantly associated with high risk of PrEP eligibility.. · A large proportion of pregnant individuals with active OUD meet criteria for PrEP prescribing.. · Risk-based screening algorithms for PrEP eligibility have limitations..

Associations between Anemia and Outcomes of Pregnant Patients with Pyelonephritis.

This study aims to determine if pregnant patients with both pyelonephritis and anemia are at an increased risk of adverse maternal outcomes compared with those with pyelonephritis without anemia. We conducted a retrospective cohort study utilizing the Nationwide Readmissions Database (NRD). Patients with antepartum pyelonephritis-associated hospitalizations from October 2015 to December 2018 were included. International Classification of Diseases codes were used to identify pyelonephritis, anemia, maternal comorbidities, and severe maternal morbidities. The primary outcome was a composite of severe maternal morbidity, as defined by the Centers for Disease Control criteria. Univariate statistical methods, weighted to account for complex survey methods in the NRD, were used to assess for associations between anemia, baseline characteristics, and patient outcomes. Weighted logistic and Poisson regressions were used to assess for associations between anemia and outcomes, adjusting for clinical comorbidities and other confounding factors. In total, 29,296 pyelonephritis admissions were identified, corresponding to a weighted national estimate of 55,135 admissions. Of these, 11,798 (21.3%) were anemic. The rate of severe maternal morbidity was higher among anemic patients than nonanemic patients (27.8 vs. 8.9%, respectively, p < 0.001), and remained higher after adjustment (adjusted relative risk [aRR] 2.86 [95% confidence interval [CI]: 2.67, 3.06]). Rates of individual components of severe maternal morbidities, including acute respiratory distress syndrome (4.0 vs. 0.6%, aRR 3.97 [95% CI: 3.10, 5.08]), sepsis (22.5 vs. 7.9%, aRR 2.64 [95% CI: 2.45, 2.85]), shock (4.5 vs. 0.6%, aRR 5.48 [95% CI: 4.32, 6.95]), and acute renal failure (2.9 vs. 0.8%, aRR 1.99 [95% CI: 1.55, 2.55]) were all higher for anemic pyelonephritis. The mean length of stay was also longer (25% average increase, 95% CI: 22, 28%). Among pregnant patients with pyelonephritis, those with anemia are at greater risk of severe maternal morbidity and longer hospital stay. · Anemia is associated with longer stays for pyelo.. · Anemic pyelo patients have increased morbidity.. · Anemic pyelo patients have increased sepsis risk..

Obesity increased the risk of SARS-CoV-2 positivity in children.

To determine the effects of obesity in childhood on SARS-CoV-2 infection. A population-based, cross-sectional study combining the Israeli Growth Survey and COVID-19 data for children with at least one SARS-CoV-2 test from 16 February 2020 to 20 December 2021. Overweight and obesity status were based on body mass index and the Center for Disease Control criteria. Multivariate logistics regression was performed to validate reliability for weight categories at the age of approximately 6 years compared with weights at approximately 12 years. A total of 444 868 records for children with an overall positivity rate of 22% were studied. The mean age was 9.5 years. The odds ratios of children with obesity or overweight after controlling for sex at 6 years to test positive were 1.07-1.12 and 1.06-1.08 (depending on the model), respectively, compared to those with healthy range body mass index. Excess weight appears to increase the risk of SARS-CoV-2 infection. This finding should be considered for public health planning. For example, children with overweight and obesity should be prioritised for vaccination. Excess weight in childhood can be harmful at a young age and not only for long-term health.

Extracorporeal Membrane Oxygenation Characteristics and Outcomes in Children and Adolescents With COVID-19 or Multisystem Inflammatory Syndrome Admitted to U.S. ICUs.

Extracorporeal membrane oxygenation (ECMO) has been used successfully to support adults with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related cardiac or respiratory failure refractory to conventional therapies. Comprehensive reports of children and adolescents with SARS-CoV-2-related ECMO support for conditions, including multisystem inflammatory syndrome in children (MIS-C) and acute COVID-19, are needed. Case series of patients from the Overcoming COVID-19 public health surveillance registry. Sixty-three hospitals in 32 U.S. states reporting to the registry between March 15, 2020, and December 31, 2021. Patients less than 21 years admitted to the ICU meeting Centers for Disease Control criteria for MIS-C or acute COVID-19. None. The final cohort included 2,733 patients with MIS-C (n = 1,530; 37 [2.4%] requiring ECMO) or acute COVID-19 (n = 1,203; 71 [5.9%] requiring ECMO). ECMO patients in both groups were older than those without ECMO support (MIS-C median 15.4 vs 9.9 yr; acute COVID-19 median 15.3 vs 13.6 yr). The body mass index percentile was similar in the MIS-C ECMO versus no ECMO groups (89.9 vs 85.8; p = 0.22) but higher in the COVID-19 ECMO versus no ECMO groups (98.3 vs 96.5; p = 0.03). Patients on ECMO with MIS-C versus COVID-19 were supported more often with venoarterial ECMO (92% vs 41%) for primary cardiac indications (87% vs 23%), had ECMO initiated earlier (median 1 vs 5 d from hospitalization), shorter ECMO courses (median 3.9 vs 14 d), shorter hospital length of stay (median 20 vs 52 d), lower in-hospital mortality (27% vs 37%), and less major morbidity at discharge in survivors (new tracheostomy, oxygen or mechanical ventilation need or neurologic deficit; 0% vs 11%, 0% vs 20%, and 8% vs 15%, respectively). Most patients with MIS-C requiring ECMO support (87%) were admitted during the pre-Delta (variant B.1.617.2) period, while most patients with acute COVID-19 requiring ECMO support (70%) were admitted during the Delta variant period. ECMO support for SARS-CoV-2-related critical illness was uncommon, but type, initiation, and duration of ECMO use in MIS-C and acute COVID-19 were markedly different. Like pre-pandemic pediatric ECMO cohorts, most patients survived to hospital discharge.

A prospective study of prenatal ventriculomegaly: natural course, survival, and neurodevelopmental status.

Prenatal ventriculomegaly (VM) is classified as mild, moderate, or severe on the basis of the diameter of the atrium. Neurodevelopmental status in prenatal VM is associated with various factors such as the course of VM, VM type, progression, and associated anomalies. In this study, the authors aimed to evaluate neurodevelopmental outcome in patients with prenatal VM and to detect possible associated risk factors. In this study, 73 pregnancies with VM who were referred to Children's Medical Center, Tehran, Iran, between 2019 and 2021 were prospectively followed. They were followed up every 2-4 weeks with ultrasonography (US) before delivery and were then observed for an average time of 14.6 months. The authors collected demographic and ultrasound information, associated abnormalities, pregnancy outcomes, and developmental status according to Centers for Disease Control criteria. The mean gestational age at the time of diagnosis was 28.1 weeks, and 46.6% of fetuses were female. According to the first US, 46.6% had mild, 21.9% had moderate, and 31.5% had severe VM. Serial US scans showed that VM had regressed in 20.5% of patients, remained stable in 35.6%, and progressed in 43.8%. Other cranial abnormalities were detected in 38.4% of fetuses. During follow-up, 62.5% of cases had normal developmental status, 26.6% had mild delay, and 10.9% had severe neurodevelopmental delay. Pregnancy was terminated in 9 (12.3%) cases. Normal neurodevelopment was reported in 75.8% of patients with mild VM versus 50% of those with severe VM (p = 0.19). Neurodevelopmental status was normal in 72.5% of cases without other cranial abnormalities (p = 0.018) and in 86.7% of cases with regression of VM (p = 0.028). Despite analysis of different factors in prenatal VM, only progression of VM and associated cranial abnormalities had significant relationships with neurodevelopmental prognosis.

Comparison of the Centers for Disease Control (CDC) recommendations and the risk index for overdose or serious opioid-induced respiratory depression (RIOSORD) tool for guiding naloxone coprescribing.

Patients treated with ongoing opioid therapy may be at an increased risk of respiratory depression or death, which may be mitigated through prompt administration of naloxone. The Centers for Disease Control (CDC) guidelines for prescribing opioids in primary care settings recommend patients treated with ongoing opioid analgesic therapy be offered a coprescription of naloxone based on total oral morphine milligram equivalents per day or concurrent benzodiazepine therapy. Opioid overdose risk is dose-dependent, yet other patient-specific factors contribute to this risk. The risk index for overdose or serious opioid-induced respiratory depression (RIOSORD) incorporates additional risk factors to assess the risk of overdose or clinically relevant respiratory depression. This study compared the frequency of meeting CDC, Veterans' Health Administration (VA) RIOSORD, or civilian RIOSORD criteria for naloxone coprescribing. A retrospective chart review of 42 Federally Qualified Health Centers in Illinois was conducted for all CII-CIV opioid analgesic prescriptions. Ongoing opioid therapy was defined as patients who received seven or more CII-CIV opioid analgesic prescriptions during the 1-year study period. Patients aged 18-89, receiving opioids for nonmalignant pain, and meeting the criteria of ongoing opioid therapy were included in the analysis. A total of 41,777 controlled substance analgesic prescriptions were prescribed during the study period. Data from 651 individual patient charts were evaluated. Of those, 606 patients met inclusion criteria. From these data, 57.9 percent of patients (N = 351) met civilian RIOSORD criteria, 36.5 percent (N = 221) met VA RIOSORD criteria, and 22.8 percent (N = 138) met CDC guideline recommendations for naloxone coprescribing. The percentage of patients who met RIOSORD criteria compared to CDC criteria was significantly higher (p < 0.001). Of all patients meeting ongoing opioid therapy criteria, only seven had been coprescribed naloxone. Coprescribing of naloxone is significantly underutilized in patients treated with opioid therapy for nonmalignant chronic pain and should not solely be based on total oral morphine milligram equivalents per day or concurrent benzodiazepine therapy. As risk assessment improves, consideration of other risk-conferring variables, such as gabapentinoids, skeletal muscle relaxants, and sleep hypnotics, should be considered.

A 5-year analysis of Candida bloodstream infections in the paediatric cardiovascular surgery ICU of a tertiary care centre.

Candida infections have become one of the most common causes of morbidity and mortality in paediatric ICUs, especially following complex surgeries, all over the world. Therefore, we conducted a 5-year analysis of Candida bloodstream infections in our tertiary paediatric cardiovascular surgery ICU. One thousand nine hundred and thirty four children, 0-16-year-old, who underwent paediatric cardiovascular surgery between January 2016-June 2021 were enrolled in this retrospective study. Blood cultures obtained from 1056 patients, who needed mechanical ventilation and indwelling devices longer than 5 days and had the signs of infection according to Center for Disease Control criteria, were evaluated. The isolated pathogens were recorded. 137 with Candida bloodstream infections were reanalysed for their age, weight, cardiac pathologies, duration of mechanical ventilation, hospitalisation and antibiotic use. One hundred and thirty-seven out of one thousand and fifty six patients (12.9%) had Candida growth in their blood cultures. C. albicans (n: 50, 36.5%), C. parapsilosis (n: 20, 14.6%), C. tropicalis (n: 8, 5.8%), C. glabrata (n: 5, 3.7%), and other non-albicans Candida species (n: 54, 39.4%) were isolated. The patients with Candida bloodstream infections had lower age, longer duration of mechanical ventilation, longer length of hospital stay and antibiotic use (p-values<0.05). They had cardiac pathologies as atrioventricular septal defect (18.9%), transposition of great arteries (17.6%), tetralogy of Fallot (12.4%), transposition of great arteries + double outlet right ventricle, or total anomalous pulmonary venous return + atrioventricular septal defect (37.9%), and others. The Candida bloodstream infections mortality was 11.6% (16/137). The most common cause of Candida bloodstream infections in the last five years in our paediatric cardiovascular surgery ICU was non-albicans Candida species. Prolonged mechanical ventilation, hospitalisation and antibiotic use, low age, and weight were found as the main risk factors that raise the morbidity and mortality rates of Candida bloodstream infections.

Primary versus delayed primary skin closure in operated patients due to perforated peptic ulcer disease: a randomized controlled clinical trial.

Perforated peptic ulcer (PPU) is a life-threatening complication of peptic ulcer disease. This condition is characterized by a dirty abdomen that predisposes to postoperative wound infection. Delayed primary skin closure is occasionally preferred over primary closure to reduce the risk of surgical site infection in dirty abdominal wounds. In primary skin closure, the skin is sutured immediately after surgery. Meanwhile, in delayed primary skin closure, the incision is left open, and sutured after 2-5days. The current research aimed to compare the risk for surgical site infection, length of hospitalization, and mortality rate between primary versus delayed primary skin closure among patients who underwent surgery for PPU. This single-blind randomized clinical trial included 120 patients who were randomly allocated into the primary and delayed primary closure groups. A research assistant who was blinded to the study examined the wounds for surgical site infection based on the 1992 Center for Disease Control criteria. The outcomes were mortality rate and duration of hospitalization. The delayed primary and primary closure groups did not significantly differ in terms of postsurgical wound infection occurring on the 3rd, 7th, 14th, and 30th days after surgery, mortality rate, and duration of hospitalization. In patients who underwent surgery for PPU, delayed primary closure is not recommended over primary closure due to the risk of postoperative surgical site infection.

Low serum transthyretin levels predict stroke-associated pneumonia

Background and aimsStroke-associated pneumonia (SAP) is commonly seen in ischemic stroke patients. Low transthyretin levels are found to be correlated with stroke. This study aims to investigate the potential relationship between transthyretin levels and SAP. Methods and resultsIn total, 920 patients were involved in our study. Serum transthyretin levels were measured within 24 h at admission. We defined SAP according to the modified Centers for Disease Control criteria. In the study population, 123 (13.4%, 77 men, 46 women) were diagnosed with SAP. In the multivariable analysis, we found that serum transthyretin levels were significantly lower in SAP compared with non-SAP patients (231 ± 80 vs. 279 ± 75; P < 0.001) after adjusting for confounders. Meanwhile, we discovered that low transthyretin levels (≤252 mg/L) were independently associated with the development of SAP (OR 3.370; 95% CI: 1.763–6.441; P < 0.001). Moreover, patients with SAP had a worse clinical outcome than those without SAP at discharge. In addition, dysphagia, leukocyte count and NLR (neutrophil-to-lymphocyte ratio) were also found to be associated with SAP. ConclusionWe found that low transthyretin levels significantly increased the risk of SAP. Patients with high risk of developing SAP could be early identified and prevented timely.

P066 ELECTIVE LICHTENSTEIN INGUINAL HERNIOPLASTY IN GERIATRIC PATIENTS WITHOUT ANTIBIOTIC PROPHYLAXIS : HOW SAFE IS IT ?

Abstract Aim Elective surgery is becoming increasingly common in geriatric patients, particularly as the population is aging. The incidence of inguinal hernia in the elderly is also increasing. Lichtenstein inguinal hernioplasty is the most frequent procedure for the elective repair. There is ambiguity about the usefulness of antibiotic prophylaxis in inguinal mesh hernioplasty and the evidence for its value is still a matter of debate. Our aim was to evaluate the outcomes of Lichtenstein inguinal hernioplasty without antibiotic prophylaxis in geriatric patients. Material and Methods A database of patients aged 70 and more undergoing elective Lichtenstein inguinal hernioplasty was established. Patients were randomly categorized in antibiotic (received antibiotics) and placebo group (received placebo). Demographics, American Society of Anesthesiologists (ASA) classification, comorbidity, hernia type, operating time and hospitalisation were analyzed. Infections were evaluated 1 week, 2 weeks and 1 month postoperatively according to Center for Disease Control criteria. Results Between 2015.-2019., 400 patients were evaluated, 200 patients in each group. All patients were operated under local anaesthesia with 24-hours hospitalisation. Groups were well matched regarding demographics, ASA-type, comorbidity, hernia type, operation time. Superficial surgical site infection developed in 16 patients from the antibiotic and 19 from the placebo group. Three from each group developed deep infection. Two mesh removal was required in the placebo group. Conclusions Prophylactic antibiotic usage in geriatric patients undergoing Lichtenstein inguinal hernioplasty did not show any significant beneficial efects in reduction of surgical site infection. Our results do not support the routine use of antibiotics for elective inguinal hernioplasty.

Randomized control trial on perioperative antibiotic prophylaxis in live liver donors: Are three doses enough?

The duration of perioperative antibiotic prophylaxis following live liver donor hepatectomy (LDH) is not known. This is a double-blind equivalence trial. All consecutive LDH were randomized into: group A (three doses) and group B (nine doses) of perioperative antibiotics (piperacillin+tazobactam-4.5g intravenous) at fixed 8hourly intervals. Primary end point was incidence of infective complications as per CDC (Centers for Disease Control and Prevention) criteria. Secondary end points were liver function tests, total leukocyte count, international normalized ratio, hospital stay, morbidity, and cost analysis. One hundred and twenty-six LDHs were enrolled. A total of 19.8% (n=25) experienced postoperative complications, 11 (17.7%) in group A and 14 (21.9%) in group B (P=.561). Infective complications were seen in 11 donors (8.1%), five in group A and six in group B (P=.79). A total of 8.1% of donors required continuation/up-gradation of antibiotics in group A and 9.4% in group B. Return to soft diet was delayed in group B (P=.039). Median hospital stay and cost were similar. Three doses of perioperative antibiotic are equally effective in preventing infective complications.

Closed incision negative pressure wound therapy is associated with reduced surgical site infection after emergency laparotomy: A propensity matched–cohort analysis

BackgroundSurgical site infection contributes to a significant proportion of postoperative morbidity in patients undergoing emergency laparotomy. Surgical site infections cause significant patient burden, increase duration of stay, and have economic implications. Closed incision negative pressure therapy has been shown to reduce surgical site infection rates in patients undergoing elective laparotomy; however, there is limited evidence for their use in the emergency setting. This study aims to compare rates of surgical site infection between patients receiving closed incision negative pressure therapy and standard surgical dressing after emergency laparotomy through a propensity matched analysis. MethodsA registry-based, prospective cohort study was undertaken using data from the National Emergency Laparotomy Audit database at our center. The primary outcome measure was surgical site infection as defined by the Centers for Disease Control criteria. Secondary outcomes included 30-day postoperative morbidity and grade, duration of stay, 30-day mortality, and readmission rates. A propensity-score matching was performed in a 1:1 ratio to mitigate for selection bias. ResultsA total of 1,484 patients were identified from the National Emergency Laparotomy Audit data set, and propensity-score matching resulted in 2 equally matched cohorts with 237 patients in each arm. The rate of surgical site infection was significantly lower in the closed incision negative pressure therapy cohort (16.9% vs 33.8%, P < .001). There were no overall differences in 30-day morbidity, Clavien-Dindo grade, Comprehensive Complication Index severity, length of hospital stay, reoperation rates, and 30-day mortality between the 2 groups. ConclusionsProphylactic closed incision negative pressure therapy in emergency laparotomy patients is associated with a reduction in surgical site infection rates.

Distinct Cytokine and Chemokine Dysregulation in Hospitalized Children With Acute Coronavirus Disease 2019 and Multisystem Inflammatory Syndrome With Similar Levels of Nasopharyngeal Severe Acute Respiratory Syndrome Coronavirus 2 Shedding.

BackgroundMultisystem inflammatory syndrome in children (MIS-C) is a severe clinical phenotype of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that remains poorly understood.MethodsHospitalized children <18 years of age with suspected coronavirus disease 2019 (COVID-19) (N = 53) were recruited into a prospective cohort study; 32 had confirmed COVID-19, with 16 meeting the US Centers for Disease Control criteria for MIS-C. Differences in nasopharyngeal viral ribonucleic acid (RNA) levels, SARS-CoV-2 seropositivity, and cytokine/chemokine profiles were examined, including after adjustments for age and sex.ResultsThe median ages for those with and without MIS-C were 8.7 years (interquartile range [IQR], 5.5–13.9) and 2.2 years (IQR, 1.1–10.5), respectively (P = .18), and nasopharyngeal levels of SARS-CoV-2 RNA did not differ significantly between the 2 groups (median 63 848.25 copies/mL versus 307.1 copies/mL, P = .66); 75% of those with MIS-C were antibody positive compared with 44% without (P = .026). Levels of 14 of 37 cytokines/chemokines (interleukin [IL]-1RA, IL-2RA, IL-6, IL-8, tumor necrosis factor-α, IL-10, IL-15, IL-18, monocyte chemoattractant protein [MCP]-1, IP-10, macrophage-inflammatory protein [MIP]-1α, MCP-2, MIP-1β, eotaxin) were significantly higher in children with MIS-C compared to those without, irrespective of age or sex (false discovery rate <0.05; P < .05).ConclusionsThe distinct pattern of heightened cytokine/chemokine dysregulation observed with MIS-C, compared with acute COVID-19, occurs across the pediatric age spectrum and with similar levels of nasopharyngeal SARS-CoV-2 RNA.
