360 Background: Clinically relevant pancreatic fistula (CR-POPF), following distal pancreatectomy (DP) remains a clinical challenge. Prior studies investigating the relationship between body mass index (BMI) and CR-POPF have yielded conflicting results. We examined this relationship utilizing our institutional database and hypothesized that BMI is associated with CR-POPF in patients having DP for pancreatic ductal adenocarcinoma (PDAC). Methods: Patients who underwent DP for PDAC at a single institution from 2007 to 2018 were retrospectively reviewed. A CR-POPF was defined as ISGPS grade B or C fistula. Uni- and multi-variable logistic regression analysis to assess factors associated with CR-POPF following DP was performed, controlling for factors such as gland texture, operative drain placement, gender, and smoking status. Results: 78 patients met the inclusion criteria. 51% were female, 51% were Caucasian, and the average age was 59 ± 15 years. The median BMI was 26 (interquartile range 24 to 29). Overall, 19% (n = 15) of patients had a CR-POPF. With a mean follow up 2.8 ± 2.5 years, the presence of a CR-POPF was not associated with long-term survival (P = 0.17). On univariable logistic regression, older age was associated with a decreased risk of CR-POPF (OR = 0.95, P = 0.015) while increasing BMI was associated with an increased risk of CR-POPF (OR = 1.1, P = 0.044). After controlling for multiple factors on multivariable logistic regression analysis, BMI (OR = 1.12, P = 0.035) was the only factor associated with development of a CR-POPF while older age (OR = 0.94, P < 0.001) was slightly protective of CR-POPF development. Conclusions: For patients undergoing DP for PDAC, increasing BMI is associated with an increased risk of CR-POPF, independent of other factors. These findings should be considered during preoperative counseling. Although there is no specific cut-off for the association between BMI and CR-POPF, efforts to diminish the risk of CR-POPF should be focused on patients with higher BMI based on this data.

The Relationship

Clinically relevant pancreatic fistula (CR-POPF), after distal pancreatectomy (DP), remains a clinical challenge. Prior studies investigating the relationship between BMI and CR-POPF have yielded conflicting results. We hypothesized that BMI is associated with CR-POPF in patients having DP for pancreatic ductal adenocarcinoma (PDAC). Patients who underwent DP for PDAC at a single institution from 2006 to 2018 were retrospectively reviewed. A CR-POPF was defined as International Study Group of Pancreatic Surgery (ISGPS) grade B or C fistula. Uni- and multivariable logistic regression analysis assessed factors associated with CR-POPF after DP. Seventy-eight patients met the inclusion criteria, 51 per cent were female, 51 per cent were white, and the average age was 59 ± 15 years. The median BMI was 26 (IQR 24–29). Of all, 19 per cent (n = 15) of patients had a CR-POPF. With a mean follow-up of 2.8 ± 2.5 years, the presence of a CR-POPF was not associated with survival ( P = 0.17). On univariable logistic regression, older age was associated with a decreased risk of CR-POPF (odds ratio (OR) = 0.95, P = 0.015). Increasing BMI was associated with an increased risk of CR-POPF (OR = 1.1, P = 0.044). On multivariate analysis, after controlling for multiple factors, BMI (OR = 1.12, P = 0.035) was the only factor associated with the development of a CR-POPF, whereas older age (OR = 0.94, P < 0.001) was slightly protective. Increasing BMI is associated with an increased risk of CR-POPF after DP for PDAC. These findings should be considered during preoperative counseling. Efforts to diminish the risk of CR-POPF should be focused on patients with higher BMI.

Abstract Background: The comorbidities commonly observed in severe Covid-19 are diagnoses that comprise the metabolic syndrome. The metabolic status of patients when infected with SARS-Cov-2 and its significance for the severity of the disease is not yet fully understood. We investigated the association between respiratory symptoms and the levels of HbA1c in hospitalized patients infected with SARS-CoV-2. Methods: In this retrospective observational study, we included all inpatients at the Karolinska University Hospital, Sweden who had both a positive SARS-CoV-2 test and who had a HbA1c test obtained within 3 months of admission. The primary reasons for hospitalization included trauma, stroke, myocardial infarction, acute or elective surgery as well as infection. Based on HbA1c level and diabetes history, we classified patients into the following dysglycemia categories: prediabetes, unknown diabetes, controlled diabetes or uncontrolled diabetes. We used multivariable logistic regression analysis adjusted for age, sex and body mass index, to assess the association between dysglycemia categories and development of respiratory failure when infected with SARS-CoV-2. Primary outcome was respiratory failure associated with SARS-CoV-2.Results: Of the 385 study patients, 88 (22.9%) had prediabetes, 68 (17.7%) had unknown diabetes, 36 (9.4%) had controlled diabetes, and 83 (21.6%) had uncontrolled diabetes. Overall, 299 (77.7%) patients were admitted with or developed SARS-CoV-2-assoociated respiratory failure during hospitalization. The proportion of patients in need of intensive care (62.5% vs 26.7%, p<0.001), mechanical ventilation (60.9% vs. 26.7%, p<0.001) and renal replacement therapy (14% vs. 1.2%, p<0.001) were all higher in patients with SARS-CoV-2 associated respiratory failure vs. patients without. In addition, 83% of the ICU patients with SARS-CoV-2 associated respiratory failure had a HbA1c > 42 mmol/mol. In multivariable logistic regression analysis compared with no chronic dysglycemia, prediabetes (OR 14.41, 95% CI 5.27-39.43), unknown diabetes (OR 15.86, 95% CI 4.55-55.36), and uncontrolled diabetes (OR 17.61, 95% CI 5.77-53.74) was independently associated with increased risk of SARS-CoV-2-induced respiratory failure.Conclusion: Metabolic imbalance, reflected by elevated HbA1c with or without previous diagnosed diabetes mellitus, was associated with a more severe course of SARS-CoV-2-respratory infection. We suggest that HbA1c could be used as a marker of risk for severe Covid-19.

Payment Models

Introduction: Hip fractures are a significant economic burden to our healthcare system. As there have been efforts made to create an alternative payment model for hip fracture care, it will be imperative to risk-stratify reimbursement for these medically comorbid patients. We hypothesized that patients readmitted to the hospital within 90 days would be more likely to have a recent previous hospital admission, prior to their injury. Patients with a recent prior admission could therefore be considered higher risk for readmission and increased cost. Methods: A retrospective chart review identified 598 patients who underwent surgical fixation of a hip or femur fracture. Data on readmissions within 90 days of surgical procedure and previous admissions in the year prior to injury resulting in surgical procedure were collected. Logistic regression analysis was used to determine if recent prior admission had increased risk of 90-day readmission. A subgroup analysis of geriatric hip fractures and of readmitted patients were also performed. Results: Having a prior admission within one year was significantly associated (p < 0.0001) for 90-day readmission. Specifically, logistic regression analysis revealed that a prior admission was significantly associated with 90-day readmission with an odds ratio of 7.2 (95% CI: 4.8-10.9). Discussion: This patient population has a high rate of prior hospital admissions, and these prior admissions were predictive of 90-day readmission. Alternative payment models that include penalties for readmissions or fail to apply robust risk stratification may unjustly penalize hospital systems which care for more medically complex patients. Conclusions: Hip fracture patients with a recent prior admission to the hospital are at an increased risk for 90-day readmission. This information should be considered as alternative payment models are developed for hip fracture care.

Abstract Background Limited data are available on practical predictors of successful de-cannulation among the patients who undergo tracheostomies. We evaluated factors associated with failed de-cannulations to develop a prediction model that could be easily be used at the time of weaning from MV. Methods In a retrospective cohort of 346 tracheostomised patients managed by a standardized de-cannulation program, multivariable logistic regression analysis identified variables that were independently associated with failed de-cannulation. Based on the logistic regression analysis, the new predictive scoring system for successful de-cannulation, referred to as the DECAN score, was developed and then internally validated. Results The model included age > 67 years, body mass index < 22 kg/m2, underlying malignancy, non-respiratory causes of mechanical ventilation (MV), presence of neurologic disease, vasopressor requirement, and presence of post-tracheostomy pneumonia, presence of delirium. The DECAN score was associated with good calibration (goodness-of-fit, 0.6477) and discrimination outcomes (area under the receiver operating characteristic curve 0.890, 95% CI 0.853–0.921). The optimal cut-off point for the DECAN score for the prediction of the successful de-cannulation was ≤ 5 points, and was associated with the specificities of 84.6% (95% CI 77.7–90.0) and sensitivities of 80.2% (95% CI 73.9–85.5). Conclusions The DECAN score for tracheostomised patients who are successfully weaned from prolonged MV can be computed at the time of weaning to assess the probability of de-cannulation based on readily available variables.

Background: Very low birth weight (VLBW) babies are at increased risk of a number of complications both immediate and late. Worldwide it has been observed that these babies contribute to a significant extent to neonatal mortality and morbidity. Aim of the study was to study the risk factors contributing to mortality in VLBW babies and to evaluate the morbidity pattern in these infants.Methods: A retrospective analysis of data retrieved from the case records of VLBW babies admitted in the NICU of Kilpauk Medical College between January 2015 to December 2015. Out of the 2360 intramural babies admitted during the study period, 99 babies were less than 1500 gms. The risk factors for these babies were analyzed for their association with the outcome. Data were statistically analyzed.Results: In present study, we found that sex of the baby, gestational age, obstetric score, birth asphyxia, pulmonary haemorrhage, ROP and presence of shock were found to be associated with increased mortality. By logistic regression analysis it was observed that birth weight of the baby (p value 0.002), duration of stay (p value 0.0006), presence of shock (p<0.0001), were the risk factors significantly associated with poor outcome.Conclusions: Among the maternal and neonatal factors analyzed in the study using logistic regression analysis, birth weight, duration of hospital stay and presence of shock were significantly related to poor outcome. Of these presence of shock was the single most important factor that predicted increased mortality.

Purpose. To evaluate sex-related differences in the prevalence of and cardiovascular risk factors related to gallstone disease (GSD) in an elderly agricultural and fishing population of Taipei, Taiwan.Methods. The study sample consisted of 6511 healthy elderly participants (3971 men and 2540 women) who were voluntarily admitted to a teaching hospital for a physical checkup in 2010. The participants’ blood samples and real-time ultrasound fatty liver results were collected.Results. The prevalence of GSD in the study population was 13.2%, which increased significantly with population age (P<.0001). Women were associated with significantly higher GSD prevalence than men (14.8% versus 12.2%; for the chi-square test,P=.003). In a multiple logistic regression analysis, female sex, older age, and metabolic syndrome (MetS) were significantly associated with GSD. Multiple logistic regression analysis also revealed that obesity (odds ratioOR=1.26, 95% confidence interval (CI): 1.09–1.44) and metabolic factors (one or 2 versus none,OR=1.48, 95% CI: 1.08–1.76) were significantly associated with GSD in women but not in men.Conclusion. In the study population, female sex, older age, and MetS were associated with higher GSD prevalence. The population exhibited other sex-related differences.

We aimed to evaluate the association between the presence of histologic chorioamnionitis (HC) and development of pulmonary hypertension (PH) during neonatal intensive care unit (NICU) stay. Data of preterm infants born at 32 weeks of gestation or less were reviewed. The development of PH and other respiratory outcomes were compared according to the presence of HC. Potential risk factors associated with the development of PH during NICU stay were used for multivariable logistic regression analysis. A total of 188 infants were enrolled: 72 in the HC group and 116 in the no HC group. The HC group infants were born at a significantly shorter gestational age and lower birthweight, with a greater proportion presenting preterm premature rupture of membrane (pPROM) > 18 h before delivery. More infants in the HC group developed pneumothorax ( P = 0.008), and moderate and severe bronchopulmonary dysplasia (BPD; P = 0.001 and P = 0.006, respectively). PH in the HC group was significantly more frequent compared to the no HC group (25.0% versus 8.6%, P = 0.002). Based on a multivariable logistic regression analysis, birthweight ( P = 0.009, odds ratio [OR] = 0.997, 95% confidence interval [CI] = 0.995–0.999), the presence of HC ( P = 0.047, OR = 2.799, 95% CI = 1.014–7.731), and duration of invasive mechanical ventilation (MV) > 14 days ( P = 0.015, OR = 8.036, 95% CI = 1.051–43.030) were significant factors. The presence of HC and prolonged invasive MV in infants with lower birthweight possibly synergistically act against preterm pulmonary outcomes and leads to the development of PH. Verification of this result and further investigation to establish effective strategies to prevent or ameliorate these adverse outcomes are needed.

Background: We have previously shown that multiple prior percutaneous coronary intervention (PCI) procedures adversely affect outcome after subsequent coronary artery bypass grafting (CABG). We were now interested to investigate this effect on a multicentric basis. Methods: Eight cardiac surgical centers from the German Federal State of North-Rhine-Westphalia provided outcome data of 37140 consecutive patients having undergone isolated first-time CABG between 01/2000 and 12/2005. Twenty-two patient characteristics and outcome variables, which are part of a collection of data claimed by the national medical quality-control commission, were retrieved from the individual databases. Three groups of patients were analyzed for overall in-hospital mortality and major adverse cardiac events (MACE): Patients without a previous PCI procedure, patients with 1 previous PCI procedure and patients with ≥2 previous PCI procedures before surgery. Unadjusted univariable and risk-adjusted multivariable logistic regression analysis were applied. Computed propensity-score matching was performed based on 15 patient major risk factors to correct for and minimize selection bias. Results: A total of 10.3% of patients had 1 previous PCI procedure, and 3.7% of patients had ≥2 previous PCI procedures. Risk-adjusted multivariable logistic regression analysis of ≥2 previous PCI significantly correlated with in-hospital mortality (odds ratio [OR], 2.0; confidence interval [CI], 1.4–3.0; P <0.0005) and MACE (OR, 1.5; CI, 1.2–1.9; P <0.0013). After propensity score matching, conditional logistic regression analysis confirmed the results of adjusted analysis. A history of ≥2 previous PCI procedures was significantly associated with in-hospital mortality (OR, 1.9; CI, 1.3–2.7; P =0.0016) and MACE (OR, 1.5; CI, 1.2–1.9; P =0.0019). Conclusions: This large multicentric trial supports earlier results of our single-center analysis, multiple previous PCI procedures significantly increased the event of in-hospital mortality and MACE after subsequent CABG.

Abstract Study question Current scientific guidelines do not clearly suggest which patients would benefit the most from a sperm DNA fragmentation (SDF) test. Summary answer We aimed to investigate potential predictive factors for altered SDF in a homogenous cohort of white-European men presenting for primary couple’s infertility. What is known already High SDF has been associated with reduced fertilization rates, reduced chances of natural conception and an increased risk of early pregnancy loss. Study design, size, duration Data from 478 consecutive men with normal or altered SDF were analysed. Infertility was defined according to the WHO criteria. Semen analysis, SDF (according to SCSA) and serum hormones were measured in every patient. Health significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Altered SDF was considered with a threshold of &gt; 30%. Participants/materials, setting, methods Descriptive statistics compared the overall characteristics of patients with normal SDF and altered SDF. Logistic regression analysis tested potential predictors of altered SDF. ROC curve was used to test the accuracy of the model in predicting SDF alteration Main results and the role of chance Of 478 patients, 253 (57.7%) had altered SDF. Median (IQR) age and BMI of the whole cohort were 38 (35-42) years and 25.1 (23.3-27.1) kg/m2 respectively. Patients with altered SDF were older (median (IQR) age: 39 (36-43) vs. 37 (34-38) years, p &lt; 0.0001), had lower sperm concentration (5 (1.1–18) vs. 17 x106/mL (6–38.8), p &lt; 0.0001), testicular volume (15.1 (12 –20) vs. 16.8 (12 – 25) Prader, p = 0.0005), and total motile sperm count (TMSC) (1.8 (0.21–10.71) vs. 11.8x106 (2–37.26), p &lt; 0.0001). Conversely, men with altered SDF had higher FSH (6.1 (3.85–9.7) vs. 4.8 (3.85 – 7.9) mIU/mL, p &lt; 0.0001) and prolactin levels (9.8 (7.43–14.04) vs. 8.3 (6.6–11.3) pg/mL, p = 0.0004) than those with normal SDF. At multivariable logistic regression analysis, patients’ age &gt;35 years (OR: 2.45, p = 0.0009), FSH &gt; 8.0 mIU/mL (OR: 2.23, p &lt; 0.0001) and lower TMSC (OR: 2.04, p = 0.002) were identified as indipendent predictors of altered SDF, after adjusting for testicular volume and CCI≥1. ROC curve (Figure 1) revealed that the model has a good predictive ability to identify patients with SDF alteration (AUC: 0.72, 95%CI: 0.67 - 0.77). Limitations, reasons for caution It is a retrospective analysis at a single, tertiary-referral academic centre, thus raising the possibility of selection biases. In spite of this, all patients have been consistently analysed over time with a rigorous follow-up, thus limiting potential heterogeneity in terms of data reporting Wider implications of the findings Primary infertile men older than 35 years, with high serum FSH and low TMSC at baseline are the ones who mostly deserve a SDF test over their diagnostic work-up and that would potentially benefit the most of certain treatments to improve SDF value, thus increasing chances of conceiving.
