Effect of anaemia and iron deficiency in heart failure with mildly reduced ejection fraction.

OBJECTIVE: The present study aims to clarify the prevalence and prognostic impact of anaemia and iron deficiency in patients with heart failure with mildly reduced ejection fraction (HFmrEF). BACKGROUND: The prognostic impact of anaemia and iron deficiency in HFmrEF has not yet been clarified. METHODS: Consecutive patients with HFmrEF were retrospectively included at one institution from 2016 to 2022. Patients with anaemia (i.e. haemoglobin <13 g/dL in males and < 12 g/dL in females) were compared to patients without, respectively patients with or without iron deficiency. The primary endpoint was all-cause mortality at 30 months (median follow-up), secondary endpoints comprised HF-related rehospitalisation. RESULTS: Two thousand one hundred and fifty four patients with HFmrEF with a median haemoglobin level of 12.2 g/dL were included. Anaemia was present in 52% of patients with HFmrEF and associated with a higher risk of all-cause mortality (44% vs. 18%; HR = 3.021; 95% CI 2.552-3.576; p =.001) and HF-related rehospitalisation (18% vs. 8%; HR = 2.351; 95% CI 1.819-3.040; p =.001) at 30 months, which was confirmed after multivariable adjustment. Although iron status was infrequently assessed in anaemics with HFmrEF (27%), the presence of iron deficiency was associated with higher risk of rehospitalisation for worsening HF (25% vs. 15%; HR = 1.746; 95% CI 1.024-2.976; p =.038), but not all-cause mortality (p =.279) at 30 months. CONCLUSION: Anaemia and iron deficiency are very common in atleast half of patients with HFmrEF and independently associated with adverse long-term prognosis.

Intraoperative radiotherapy (IORT) of early breast cancer with low-energy x-rays in breast-conserving surgery : Prospective identification of pre- and intraoperative factors influencing the feasibility of IORT.

PURPOSE: The aim of this study is to identify pre- and intraoperative factors indicating the feasibility of intraoperative radiotherapy (IORT) during breast-conserving surgery (BCS). MATERIALS AND METHODS: From January 2018 to December 2019, a total of 128 women undergoing BCS due to early breast cancer were included in this prospective observational study, independent of whether IORT was planned or not. Patient and tumor characteristics as well as surgical parameters that could potentially influence the feasibility of IORT were recorded for the entire collective. In addition, a preoperative senological assessment was performed and analyzed to assess the feasibility of IORT. Logistic regression was then used to identify relevant preoperative parameters and to generate a formula predicting the feasibility of IORT. RESULTS: Of the 128 included women undergoing BCS, 46 were preoperatively rated to be feasible, 20 to be questionably feasible for IORT. Ultimately, IORT was realized in 30 patients. The most frequent reasons for omission of IORT were insufficient tumor-to-skin distance and/or an excessively large tumor cavity. Small clinical tumor size and large tumor-to-skin distance according to preoperative ultrasound were significantly related to accomplishment of IORT. CONCLUSION: We observed that preoperative ultrasound-based tumor-skin distance is a significant factor in addition to already known parameters to predict feasibility of IORT. Based on our findings we developed a formula to optimize IORT planning which might serve as an additional tool to improve patient selection for IORT in early breast cancer.

Differences in neonatal gastric tubes during insertion into a 3D model in relation to risk of potential perforation.

OBJECTIVES: Perforation of esophagus or stomach is a potential complication during and after insertion of a gastric tube in neonates. The aim of this study was to analyze different types of gastric tubes in a three-dimensional (3D) model of neonatal esophagus and stomach regarding potential perforations. METHODS: A 3D model of esophagus and stomach was created based on computed tomography data of a term neonate. Three types of gastric tubes were inserted into the 3D model, the localization was examined by radioscopy and the behavior, stiffness and manageability of each gastric tube was evaluated. RESULTS: Insertion of gastric tubes with higher stiffness was easier. The rates of correct localization differed significantly between the gastric tubes with the highest rate of correct localization in the softest tube (48.5%) and the lowest rate in the tube with the highest stiffness (21.2%). Additionally, the softest tube showed the lowest rate of localization of its tip at the stomach wall. CONCLUSIONS: The study illustrates differences between various types of gastric tubes regarding stiffness, behavior and resiliency. Softer gastric tubes may be beneficial. These differences may be relevant in neonatal care of very immature and very sick infants.

Influence of motivational interviewing on postoperative mobilization in the enhanced recovery after surgery (ERAS®) pathway in elective colorectal surgery - a randomized patient-blinded pilot study.

PURPOSE: Early mobilization is an essential component of the Enhanced Recovery after Surgery (ERAS®)-pathway. However, a large percentage of patients fail to achieve the ERAS® recommended goal (360 min out of bed from post-operative day 1/POD1). Motivational Interviewing (MI) is an evidence-based type of patient-centered consultation to promote intrinsic motivation. This study aims to evaluate if MI can improve postoperative mobilization. METHODS: This two-arm, patient-blinded pilot randomized controlled trial included ERAS®-patients undergoing elective bowel resections. Conversations were validated by MI Treatment Integrity. Two validated motion sensors (movisens) and self-assessments were used to measure mobilization (POD1-POD3: Time out of bed, time on feet and step count). RESULTS: 97 patients were screened, 60 finally included and randomized. Cumulatively across POD1-3, the intervention group (IG) was longer out of bed than the control group (CG) (median: 685 vs. 420 min; p=0.022). The IG achieved the ERAS®-goal of 360 min/day more frequently across POD1-3 (27.4% vs. 10.61%; p=0.013). Time on feet was 131.5 min/day (median per POD) in IG vs. 95.8 min/day in the CG (p=0.212), step count was 1347 in IG vs. 754 steps/day in CG (p=0.298). CONCLUSION: MI could be conducted low threshold and was well accepted by patients. MI can improve mobilization in the context of ERAS®. Despite better performance, it should be noted that only 27.4% of the IG reached the ERAS®-compliance goal of 360 min/day. The findings of this pilot study stipulate to further test the promising perioperative effects of MI within a multicenter superiority trial. REGISTRATION: This study was registered prospectively in the German Clinical Trials Register on 25.02.2022. Trial registration number is "DRKS00027863".

Patient characteristics and disease spectrum in a German vascular anomalies center.

BACKGROUND: Vascular malformations are rare diseases that should be treated in dedicated vascular anomaly centers (VAC). There is only a small amount of data on the diagnostic and therapeutic handling of these patients, before they are referred to a VAC. PURPOSE: To demonstrate the disease-specific patient characteristics in a German VAC, which are required to determine diagnostic and therapeutic steps. MATERIAL AND METHODS: In a retrospective study, all patients who were treated in the VAC from April 2014 until August 2021 were identified. In total, 593 patients were included in this study. RESULTS: Almost all patients had previously consulted a physician (591/593, 99.7%). A mean of two different physicians had been consulted (range 0-10). Patients with more complex, syndromal vascular malformations had significantly more previous appointments (P = 0.0018). In only 44% (261/593) of patients, the referral diagnosis was made correctly. Most patients had been previously treated for their vascular anomaly: pharmacotherapy (n = 130; 21.9%), compression garments (n = 141; 23.8%), surgical resection (n = 80; 17.3%) and sclerotherapy (n = 68; 11.5%). Fifty-two patients who had been falsely diagnosed had also received therapy prior to their referral to the VAC (8.8%). Most patients received an ultrasound examination in the VAC (n = 464; 78.2%). Most frequently, compression therapy was prescribed (n = 256; 43.2%), followed by sclerotherapy (n = 175, 29.5%) and pharmacotherapy (n = 55; 9.3%). CONCLUSION: Patients suffering from vascular anomalies often go through a complicated scheduling with numerous outpatient appointments and have a high risk of misdiagnosis and mistreatment prolonging the medical condition. Therefore, patients with vascular anomalies should be treated in a dedicated vascular anomaly center.

Plasma-derived small extracellular vesicles unleash the angiogenic potential in head and neck cancer patients.

BACKGROUND: In Head and neck cancer (HNC) angiogenesis is essential for tumor progression and metastasis. Small extracellular vesicles (sEVs) from HNC cell lines alter endothelial cell (EC) functions towards a pro-angiogenic phenotype. However, the role of plasma sEVs retrieved from HNC patients in this process is not clear so far. METHODS: Plasma sEVs were isolated on size exclusion chromatography columns from 32 HNC patients (early-stage UICC I/II: 8, advanced-stage UICC III/IV: 24), 12 patients with no evident disease after therapy (NED) and 16 healthy donors (HD). Briefly, sEVs were characterized by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), BCA protein assays and Western blots. Levels of angiogenesis-associated proteins were determined using antibody arrays. The interaction of fluorescently-labeled sEVs with human umbilical vein ECs was visualized by confocal microscopy. The functional effect of sEVs on tubulogenesis, migration, proliferation and apoptosis of ECs was assessed. RESULTS: The internalization of sEVs by ECs was visualized using confocal microscopy. Based on antibody arrays, all plasma sEVs were enriched in anti-angiogenic proteins. HNC sEVs contained more pro-angiogenic MMP-9 and anti-angiogenic proteins (Serpin F1) than HD sEVs. Interestingly, a strong inhibition of EC function was observed for sEVs from early-stage HNC, NED and HD. In contrast, sEVs from advanced-stage HNC showed a significantly increased tubulogenesis, migration and proliferation and induced less apoptosis in ECs than sEVs from HD. CONCLUSIONS: In general, plasma sEVs carry a predominantly anti-angiogenic protein cargo and suppress the angiogenic properties of ECs, while sEVs from (advanced-stage) HNC patients induce angiogenesis compared to HD sEVs. Thus, tumor-derived sEVs within the plasma of HNC patients might shift the angiogenic switch towards angiogenesis.

Prevalence of higher-grade dysplasia in persistently high-risk human papillomavirus positive, cytology negative women after introduction of the new cervical cancer screening in Germany.

PURPOSE: According to the recently implemented organized cervical cancer screening program in Germany, women older than 35 years with negative cytology but persistent high-risk human papilloma virus (hrHPV) infection > 12 months should be referred to colposcopy for further evaluation. This study aimed to present and dissect colposcopic and histopathological findings with particular focus on associated hrHPV genotypes. METHODS: This study is a retrospective analysis of clinical data from 89 hrHPV positive patients with normal cytology who underwent colposcopic examination at a certified dysplasia outpatient clinic in Germany in 2021. RESULTS: While 38 (43%) women had a normal colposcopic finding, 45 (51%) had minor and 6 (7%) major changes. Thirty-one (35%) of the women were HPV 16 and/or HPV 18 positive and 58 (65%) women were positive for other hrHPV only. Among patients who underwent colposcopy with biopsies (in case of an abnormal finding or type 3 transformation zone, n = 68), eight (12%) had cervical intraepithelial neoplasia (CIN) 3 and six (9%) had CIN 2. The proportion of women diagnosed with CIN 3 varied among different hrHPV genotypes (HPV 16: 11%, HPV 18: 33%, HPV 31: 27%, HPV 33: 33%, HPV 52: 33%). CONCLUSION: Persistently hrHPV positive women with negative cytology are at increased risk of being diagnosed with CIN 3. As CIN 3 prevalence seems to differ with regard to hrHPV strain, immediate HPV genotyping for risk stratification and subsequent early referral for colposcopy might constitute a feasible strategy.

ASXL1 mutations are associated with a response to alvocidib and 5-azacytidine combination in myelodysplastic neoplasms.

Inhibitors of anti-apoptotic BCL-2 family proteins in combination with chemotherapy and hypomethylating agents (HMAs) are promising therapeutic approaches in acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS). Alvocidib, a cyclin-dependent kinase 9 (CDK9) inhibitor and indirect transcriptional repressor of the anti-apoptotic factor MCL-1, has previously shown clinical activity in AML. Availability of biomarkers for response to the alvocidib + 5- AZA could also extend the rationale of this treatment concept to high-risk MDS. In this study, we performed a comprehensive in vitro assessment of alvocidib and 5-AZA effects in n=45 high-risk MDS patients. Our data revealed additive cytotoxic effects of the combination treatment. Mutational profiling of MDS samples identified ASXL1 mutations as predictors of response. Further, increased response rates were associated with higher gene-expression of the pro-apoptotic factor NOXA in ASXL1 mutated samples. The higher sensitivity of ASXL1 mutant cells to the combination treatment was confirmed in vivo in ASXL1Y588X transgenic mice. Overall, our study demonstrated augmented activity for the alvocidib + 5-AZA combination in higher-risk MDS and identified ASXL1 mutations as a biomarker of response for potential stratification studies.

Diagnostic and prognostic value of the AST/ALT ratio in patients with sepsis and septic shock.

OBJECTIVE: The study investigates the diagnostic and prognostic value of the aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio in patients with sepsis and septic shock. Limited data regarding the prognostic value of the AST/ALT ratio in patients suffering from sepsis or septic shock is available. METHODS: Consecutive patients with sepsis and septic shock from 2019 to 2021 were included monocentrically. Blood samples were retrieved from day of disease onset (day 1), day 2, 3, 5 and 7. First, the diagnostic value of the AST/ALT ratio was tested for septic shock compared to sepsis. Second, the prognostic value of the AST/ALT ratio was tested for 30-d all-cause mortality. Statistical analyses included univariable t-test, Spearman's correlation, C-statistics, Kaplan-Meier analyses, as well as multivariable mixed analysis of variance (ANOVA), Cox proportional regression analyses and propensity score matching. RESULTS: A total of 289 patients were included, of which 55% had sepsis and 45% septic shock. The overall rate of all-cause mortality at 30 d was 53%. With an area under the curve (AUC) of 0.651 on day 1 and 0.794 on day 7, the AST/ALT ratio revealed moderate but better diagnostic discrimination of septic shock compared to bilirubin. Furthermore, the AST/ALT ratio was able to discriminate 30-d all-cause mortality (AUC = 0.624; 95% CI 0.559 - 0.689; p = 0.001). Patients with an AST/ALT ratio above the median (>1.8) had higher rates of 30-d all-cause mortality compared to lower values (mortality rate 63 vs. 43%; log-rank p = 0.001), even after multivariable adjustment (HR = 1.703; 95% CI 1.182 - 2.453; p = 0.004) and propensity score matching. CONCLUSIONS: The AST/ALT was a reliable diagnostic tool for the diagnosis of septic shock as well as a reliable tool to predict 30-d all-cause mortality in patients suffering from sepsis and septic shock.

Long-term characterization of MRI-morphologic alterations after active motion-compensated liver SBRT: a multi-institutional pooled analysis.

BACKGROUND: Stereotactic body radiotherapy (SBRT) is an effective therapeutic approach in patients with liver metastases. However, long-term changes in hepatic normal tissue have to be taken into account in multimodal treatment regimes. Magnetic-resonance-imaging (MRI) based morphologic liver alterations (MMA) after liver SBRT have been analyzed longitudinally. MATERIAL AND METHODS: 57 patients treated with gantry-based or robotic-based SBRT of 69 treatment volumes of liver metastases, who had long-term follow-up (FU) ≥6 months were included in this retrospective analysis. Post-SBRT MMAs were contoured on each contrast-enhanced-T1-weighted (T1w) MRI-sequence. Morphologic/volumetric data of the liver and MMAs were evaluated longitudinally, including the dependency on treatment-related factors of the planning target volume (PTV) and liver. RESULTS: The median FU time was 1 year [6-48 months]. 66 of 69 treatment volumes developed MMAs (mean 143.8 ± 135.1 ccm at first appearance). 31.8% of MMAs resolved completely during FU. Of the persisting MMAs 82.2%/13.3% decreased/increased in size until last available FU. Morphological characterization of the MMAs at first appearance included 75% hypointense and 25% hyperintense T1w-MRI-based appearances. Hypointense as compared to hyperintense appearance was significantly associated with a higher mean liver dose EQD2α/ß=3 Gy (p = 0.0212) and non-significantly greater MMA size. Variance analysis demonstrated a significant reduction of MMA and total liver volume after SBRT (p < 0.0001). The volume reduction decelerated longitudinally for both MMA (p < 0.0001) and liver size (p = 0.0033). Radiation doses (PTV-BEDα/ß=3 Gy and 10 Gy) were not significantly associated with MMA volume reduction. SBRT of liver metastases with mean liver dose EQD2α/ß=3 Gy > 18 Gy were characterized by greater MMA volumes (p = 0.0826) and steeper MMA reduction gradients during FU than those with EQD2α/ß=3 Gy ≤ 18 Gy (p < 0.0001). CONCLUSION: Radiogenic MMAs either completely resolve or usually decrease in volume with pronounced reduction during short-term FU. This course was independent of the MMA's morphological appearance. Further, increased mean liver dose was associated with greater MMA size and a greater gradient of MMA size reduction during FU.

Distance Matters: Correlation of Hepatocellular Carcinoma Nodule Distance to Overall Survival.

INTRODUCTION: Hepatocellular carcinoma (HCC) may occur with several simultaneous tumor foci in the liver (multifocal HCC). Molecular biology indicated that the larger the distance between two tumor nodules, the more those two nodules differed in their genetic composition. Therefore, we explored whether the overall survival (OS) of patients with HCC depends on the mutual distance of the HCC nodules. METHODS: In a retrospective study of 92 patients, CT/MRI images and survival data of the patients were collected. Based on the CT or MRI images at the time of diagnosis, the size of each tumor, the distance between the centers (center distance), and adjacent edges (edge distance) of the tumor nodules were measured, respectively. These data, combined with the number of tumor nodules and clinical characteristics, were compared with the patient's OS data. RESULTS: As expected, the average tumor diameter was significantly associated with patient survival in univariate Cox regression analysis (p = 0.00028, hazard ratio [HR] = 1.2). However, in multivariate analysis, the average center distance (p = 0.036, HR = 1.18) and average edge distance (p = 0.033, HR = 0.84) were also significantly associated with survival. CONCLUSION: Thus, not only the size of multiple HCC lesions but also their distance is important for the prognosis of patients with HCC. This may be of particular interest in patients with two nodules and BCLC B and C stages for the selection of therapeutic modalities and/or procedures.

Depression in brain tumor patients-early detection and screening.

BACKGROUND: Depres sion is reported in up to 90% of cancer patients but to this date, a standardized screening tool for depression specifically modified for patients diagnosed with brain tumors is lacking. Thus, this study aims to develop an adapted screening tool and identify a suitable time slot for screening. METHODS: Sixty-one patients with brain lesions were interviewed prior to neurosurgical resection. For screening purposes, established depression scores were used. A study-specific questionnaire (SSQ) was developed based on patient interviews prior to the trial. Two subgroups were analyzed: patients with benign and patients with malignant tumors (including brain metastases). As a subgroup within malignant lesions, patients with glioblastoma (GBM) were also analyzed separately. RESULTS: Of patients, 87.5% with GBM presented with results > 16 points on the Center for Epidemiologic Studies Depression Scale (CES-D) after surgery. A decline in patients with benign brain tumors (p = 0.0058) and an increase in patients with malignant tumors (p = 0.0491) could be shown over time for CES-D scores. In this study, we established a new prototype screening tool for depression. In patients diagnosed with GBM, the number of patients needed to screen for identification of symptoms of depression was 1.59. Best time for screening was 35 days after surgery. CONCLUSIONS: Considering the high prevalence and low number needed to screen of depression in patients diagnosed with GBM, we strongly encourage their routine screening during follow-up appointments (35 days after surgery). We encourage a plan to further establish the questionnaire developed in this pilot study.

Personalized checkpoint acupuncture can reduce postoperative pain after abdominal surgery-a STRICTA-conform pilot study.

BACKGROUND: Optimal pain management is one of the core elements of Enhanced Recovery After Surgery (ERAS®) protocols and remains a challenge. Acupuncture (AC) is an effective treatment for various pain conditions. Systematic and personalized allocation of acupoints may be decisive for efficacy. METHODS: Based on the predominant pressure sensitivity of six gastrointestinal (GI) checkpoints (G1-G6), we devised a method to detect personalized patterns of pain and a corresponding set of acupoints. We performed a single AC treatment with semi-permanent needles and assessed the visual analogue scale (VAS) score, pain threshold based on pressure algometry (PA), and temperature changes on abdominal skin areas before and 5 min after AC. RESULTS: Between April and June 2021, thirty-eight patients were prospectively included in this pilot study. The mean reduction in subjective pain sensation as assessed by VAS was 86%, paralleled by an augmentation of the pain threshold as measured by PA by 64%. A small but significant increase in the skin temperature was observed above the abdominal surface. These effects were independent of the type of surgery. CONCLUSION: Checkpoint acupuncture may be a complementary tool for postoperative pain management. Further investigations are needed to explore this analgesic effect.

A comparative observational study on intrasphincteric injections with Botulinum toxin vs. enteral neuromodulation in chronic refractory constipation.

PURPOSE: Botulinum toxin injections in the anal sphincter apparatus (Botox) and enteral neuromodulation (ENM) are options for treatment of refractory chronic constipation. We present a retrospective comparative observational study. PATIENTS AND METHODS: From 2014 to 2022, pediatric patients with chronic constipation were either treated with Botox or ENM with continuation of conservative treatment. Comparison was conducted regarding the primary outcome variables defecation frequency, stool consistency, and abdominal pain. Secondary outcomes were fecal incontinence, enuresis, change of medication and safety of treatment. RESULTS: 19 Botox patients (10 boys, 9 girls, 12 patients with Hirschsprung disease (HD), 7 patients with functional constipation (FC)) were compared to 24 ENM patients (18 boys, 6 girls, 12 HD patients, 7 FC patients). Groups differed significantly in age (5.0 years (Botulinum toxin) and 6.5 years (ENM), mean values, p-value 0.008). Improvement of constipation was seen in 68% (n = 13/19) of Botox and 88% (n = 21/24) of ENM patients (p = 0.153). Influence of etiology on therapeutic effects was not observed. Complications were minor. CONCLUSIONS: Botox and ENM can be considered as valuable and effective treatment options in refractory chronic constipation. Prospective, large-population studies should be designed to enable improved evidence.

Performance of a vascular anomaly center: a retrospective analysis of 461 cases over seven years.

BACKGROUND: Vascular malformations are rare diseases that are best managed in multidisciplinary vascular anomaly centers (VAC). So far, there are few published data on the logistic structure, patient allotment, and internal workflow in an interdisciplinary VAC. PURPOSE: To demonstrate the referral structure and patient allotment in a European VAC. MATERIAL AND METHODS: A retrospective cohort study was conducted. All patients treated in the VAC since its establishment in April 2014 until June 2020 were identified. A total of 461 patients were included in this study. RESULTS: Most often, a venous malformation was diagnosed (49.9%), followed by arteriovenous malformations (8.7%) and syndromal vascular malformations (8.2%). Only 45.1% of referral diagnoses were correct. Of referrals, 35.1% were internal on-campus references, 28.0% were external references through physicians in private practice, and 19.7% came via external cooperating hospitals. Of the patients, 17.1% were self-admissions without a referral. CONCLUSION: The most important referring clinics are internal medicine, pediatric, and vascular surgery. A substantial proportion of referrals came from private practices. Recruiting these cooperation partners should be considered a high priority when establishing a new VAC. The rate of misdiagnosis is high, and more education of fellow clinicians is urgently needed. Therefore, patients with vascular malformations should be referred to and treated in dedicated centers for vascular anomalies.

The Subdiaphragmatic Angle Of The Gastric Tube In Neonates - A Potential Predictor For Perforations?

BACKGROUND: Traumatic subdiaphramatic perforation of esophagus or stomach in neonates represents a rare clinical complication following the insertion of a gastric tube and is associated with high morbidity and mortality. The aim of the present study was to evaluate whether the angle of the gastric tube depicted on a plain radiograph may serve as a diagnostic tool to predict subdiaphragmatic traumatic (or iatrogenic) perforation. PATIENTS AND METHODS: Thoraco-abdominal radiographs of 128 preterm and term neonates without perforation and 15 neonates with perforation of the esophagogastric junction or the stomach were retrospectively analysed. RESULTS: The angle of the gastric tube increases with postnatal age (p=0.0380). In the control group, the angle of the gastric tube varied between 13° and 48° (median: 31°), whereas the values ranged from -31° to 42° (median: 11°) in neonates with subdiaphragmatic perforation. Perforation should thus be suspected in cases with an angle of<20° (sensitivity: 93.3%; specificity: 91.4%). Moreover, an unusual localization of the tip beyond the gastric bubble is highly indicative of perforation. DISCUSSION: The present study emphasizes the importance of verifying the correct course of an inserted gastric tube. CONCLUSIONS: In daily clinical practice, an angle of<20° should be followed by thorough physical examination, abdominal ultrasound and if applicable contrast medium examinations to exclude perforation.

Perioperative Antibiotic Prophylaxis in Radical Prostatectomy: "Single-Shot" versus Multiday Regimen.

INTRODUCTION: Perioperative antibiotic prophylaxis (AP) is common in radical prostatectomy (RP). Yet there is no standard recommendation in international guidelines due to poor evidence. It is of great importance that these perioperative AP are sufficiently checked and systemically validated. The objective of this study was to determine whether a "single-shot" (single-use) perioperative AP yields equivalent results compared to a multiday prophylaxis in RP regarding postoperative wound infections and urinary tract infections. METHODS: 376 patients treated by RP at the University Medical Centre Mannheim, from 2014 to 2016, were included in this retrospective study. RP was performed either in a robotic-assisted or open manner. One group received an intravenous dose of perioperative AP with either ciprofloxacin or levofloxacin, continued by an oral dose of AP with ciprofloxacin or levofloxacin until catheter removal, while the other group received a single-shot intravenous perioperative AP with either ciprofloxacin or cefuroxime. RESULTS: There was no significant difference regarding the occurrence of postoperative infections between both AP regimes (p = 0.5). Age, body mass index, and ASA classification did not differ significantly between both groups (p > 0.25). Except for surgery time (p < 0.05), perioperative parameters, such as the preoperative presence of germ-free urine culture, length of hospital stay, catheter time, drain lay time, Gleason score, and TNM stadium, did not differ significantly. CONCLUSION: The present study shows that perioperative single-shot AP does not entail any disadvantage compared to the multiday AP in terms of postoperative infections after RP.

Predicting Complexity in Transurethral Resection of Bladder Tumours: External Validation and Modification of the Bladder Complexity Score.

INTRODUCTION: First external validation of the Bladder Complexity Score (BCS) for predicting complex transurethral resection of bladder tumours (TURBT). METHODS: For BCS calculation, TURBTs performed at our institution between January 2018 and December 2019 were reviewed for the presence of preoperative characteristics listed in the Bladder Complexity Checklist (BCC). Receiver operating characteristics (ROC) analysis was used for BCS validation. To establish a modified BCS (mBCS) with maximum area under the curve (AUC), multivariable logistic regression (MLR) analysis was performed with all BCC-characteristics for different definitions of complex TURBT. RESULTS: 723 TURBTs were included in statistical analyses. Cohort's mean BCS was 11.2 ± 2.4 points (range: 5.5-22 points). In ROC analysis, BCS could not predict complex TURBT (AUC 0.573 [95% CI: 0.517-0.628]). MLR identified tumour size (OR 2.662, p < 0.001), and tumour number > 10 (OR 6.390, p = 0.032) as sole predictors for the modified endpoint of complex TURBT defined as a procedure meeting > 1 criterion: incomplete resection, surgery > 1 h, intraoperative complication, postoperative complications Clavien-Dindo ≥ III. mBCS increased the prediction to an AUC of 0.770 (95% CI: 0.667-0.874). CONCLUSION: In this first external validation, BCS remained an insufficient predictor of complex TURBT. mBCS requires reduced parameters, is more predictive and easier to apply in clinical practice.

The hysterectomy: influence of the surgical method in benign disease on convalescence and quality of life.

PURPOSE: The aim of this study was to evaluate the postoperative course after different methods of hysterectomy for benign diseases with special emphasis on time to recovery and patient-centred aspects such as postoperative quality of life and satisfaction. METHODS: A collective of 242 women who had undergone vaginal hysterectomy (VH), laparoscopic supracervical hysterectomy (LASH) or total laparoscopic hysterectomy (TLH) for various benign conditions was studied in this retrospective investigation. Patients completed a standardised questionnaire addressing quality of life, recovery and sick leave as well as general questions on their postoperative course after hysterectomy. RESULTS: A total of 242 cases were analysed (82 VH, 92 LASH and 68 TLH). The data demonstrate significant differences in regard to age between groups. The present study shows shorter hospitalisation with laparoscopy, with LASH patients returning to work at least one week earlier on average. There were no relevant differences in the overall postoperative course during the index hospital stay. In the long run, laparoscopic patients were not more satisfied with their choice than VH patients. CONCLUSION: No significant long-term differences could be observed in terms of quality of life and overall postoperative satisfaction between VH and LH groups. In regard to socioeconomic aspects, laparoscopic approaches were associated with shorter hospitalisation and LASH patients returning to work at least one week earlier on average. Contrary to these data on objective recovery; however, a laparoscopic approach did not lead to patient-perceived, i.e. subjective improvement of time to full recovery.

First experiences with a diode laser in major gynecological laparoscopic procedures show lack of benefit and impaired feasibility.

PURPOSE: The aim of this study is to evaluate feasibility and potential benefit of a diode laser in major laparoscopic procedures in gynecology. METHODS: Between 2018 and 2020, a total of 42 cases were enrolled in this study comparing standard electrosurgery with diode laser-supported therapy in laparoscopic supracervical hysterectomy (LASH), total laparoscopic hysterectomy (TLH), or laparoscopic myoma enucleation (LME). Dual wavelength 45 W diode laser light was used to cut and coagulate during laparoscopy in the prospective interventional arm consisting of 11 cases, while 31 matching patients who received conventional treatment with monopolar/bipolar current for the same interventions were retrospectively identified in our laparoscopy database. Recruitment in the prospective interventional laser diode arm was terminated after only 11 patients (instead of planned 50) due to intense hemorrhage and massive smoke development. RESULTS: A total of 42 cases were analyzed (11 LME, 19 LASH, and 12 TLH). Strong smoke development was evident in all 11 cases in the diode laser arm. It was necessary to convert to bipolar or monopolar current in all hysterectomies (n = 9) with initial diode laser implementation due to increased bleeding and smoke development. Conventional current sources had to be used in LMEs (n = 2) due to excessive bleeding and poor visibility during enucleation of the fibroid. A significant difference (p < 0.0001) was observed regarding smoke development when comparing the laser arm with the control arm. CONCLUSION: We found a 45-W diode laser to be inferior to electrosurgical techniques for major laparoscopic gynecologic surgeries regarding bleeding control and smoke development.
