Keyword-augmented and semi-automatic generation of FESS reports: a proof-of-concept study.

INTRODUCTION: Surgical reports are usually written after a procedure and must often be reproduced from memory. Thus, this is an error-prone, and time-consuming task which increases the workload of physicians. In this proof-of-concept study, we developed and evaluated a software tool using Artificial Intelligence (AI) for semi-automatic intraoperative generation of surgical reports for functional endoscopic sinus surgery (FESS). MATERIALS AND METHODS: A vocabulary of keywords for developing a neural language model was created. With an encoder-decoder-architecture, artificially coherent sentence structures, as they would be expected in general operation reports, were generated. A first set of 48 conventional operation reports were used for model training. After training, the reports were generated again and compared to those before training. Established metrics were used to measure optimization of the model objectively. A cohort of 16 physicians corrected and evaluated three randomly selected, generated reports in four categories: "quality of the generated operation reports," "time-saving," "clinical benefits" and "comparison with the conventional reports." The corrections of the generated reports were counted and categorized. RESULTS: Objective parameters showed improvement in performance after training the language model (p < 0.001). 27.78% estimated a timesaving of 1-15 and 61.11% of 16-30 min per day. 66.66% claimed to see a clinical benefit and 61.11% a relevant workload reduction. Similarity in content between generated and conventional reports was seen by 33.33%, similarity in form by 27.78%. 66.67% would use this tool in the future. An average of 23.25 ± 12.5 corrections was needed for a subjectively appropriate surgery report. CONCLUSION: The results indicate existing limitations of applying deep learning to text generation of operation reports and show a high acceptance by the physicians. By taking over this time-consuming task, the tool could reduce workload, optimize clinical workflows and improve the quality of patient care. Further training of the language model is needed.

Screening for distress, related problems and perceived need for psycho-oncological support in head and neck squamous cell carcinoma (HNSCC) patients: a retrospective cohort study.

BACKGROUND: In different cancer entities, several studies have shown the adverse effects of cancer on mental health, psychological well-being and the increased risk of high emotional distress in cancer patients. This study aims to analyze psychosocial distress levels and their relationship between sociodemographic parameters and selected items on the Distress Thermometer (DT) Problem List in head and neck squamous cell carcinoma (HNSCC) patients. PATIENTS AND METHODS: We assessed a total of 120 HNSCC patients using the Distress Thermometer (DT) Problem List. Distress scores (DTS) of 90 patients were available. A DTS of ≥ 5 on the visual analogue scale represents clinically relevant distress. Data analysis consisted of descriptive statistics, comparison of mean values for different DTS subcategories and correlation between DTS scores and parameters of tumor classification, sociodemographic variables and selected problems. RESULTS: Distress was present in 57.7% of the sample, with a total of 52 patients with a DTS  ≥ 5. The mean DTS was 4.7 (SD 2.4). Patients with newly diagnosed HNSCC had significantly higher DTS. Distress levels were significantly associated with sadness, general worries, anxiety, nervousness, sleeping disorders, mouth sores and fever. Out of the total sample, 6 patients and out of these 6 individuals, 5 patients with a DTS ≥ 5 requested referrals to psycho-oncological service. CONCLUSION: High distress levels were common in HNSCC patients but only few patients desired psycho-oncological care. Addressing patients' supportive care needs in routine clinical practice is essential to meet unmet needs of HNSCC patients and thus improve cancer care.

Apolipoprotein B and angiotensin-converting enzyme polymorphisms and aerobic interval training: randomized controlled trial in coronary artery disease patients.

Physical training has been strongly recommended as a non-pharmacological treatment for coronary artery disease (CAD). Genetic polymorphisms have been studied to understand the biological variability in response to exercise among individuals. This study aimed to verify the possible influence of apolipoprotein B (ApoB: rs1042031 and rs693) and angiotensin-converting enzyme (ACE-ID: rs1799752) genotypes on the lipid profile and functional aerobic capacity, respectively, after an aerobic interval training (AIT) program in patients with CAD and/or cardiovascular risk factors. Sixty-six men were randomized and assigned to trained group (n=32) or control group (n=34). Cardiopulmonary exercise test was performed to determine the ventilatory anaerobic threshold (VAT) from cardiorespiratory variables. The AIT program, at an intensity equivalent to %VAT (70-110%), was conducted three times a week for 16 weeks. ApoB gene polymorphisms (-12669C>T (rs1042031) and -7673G>A (rs693)) were identified by real-time polymerase chain reaction (PCR). I/D polymorphism in the ACE gene (rs1799752) was identified through PCR and fragment size analysis. After 16 weeks, low-density lipoprotein (LDL) levels increased in the trained and control groups with the GA+AA genotype (-7673G>A) of the ApoB gene. Trained groups with ACE-II and ACE-ID genotypes presented an increase in oxygen consumption (VO2VAT) and power output after the AIT program. The presence of the ACE I-allele was associated with increased aerobic functional capacity after the AIT program. Increased LDL levels were observed over time in patients with the -7673G>A polymorphism of the ApoB gene. Trial Registration Information: ClinicalTrials.gov: NCT02313831.

Linear and nonlinear analysis of heart rate variability in healthy subjects and after acute myocardial infarction in patients

The objectives of this study were to evaluate and compare the use of linear and nonlinear methods for analysis of heart rate variability (HRV) in healthy subjects and in patients after acute myocardial infarction (AMI). Heart rate (HR) was recorded for 15 min in the supine position in 10 patients with AMI taking β-blockers (aged 57 ± 9 years) and in 11 healthy subjects (aged 53 ± 4 years). HRV was analyzed in the time domain (RMSSD and RMSM), the frequency domain using low- and high-frequency bands in normalized units (nu; LFnu and HFnu) and the LF/HF ratio and approximate entropy (ApEn) were determined. There was a correlation (P < 0.05) of RMSSD, RMSM, LFnu, HFnu, and the LF/HF ratio index with the ApEn of the AMI group on the 2nd (r = 0.87, 0.65, 0.72, 0.72, and 0.64) and 7th day (r = 0.88, 0.70, 0.69, 0.69, and 0.87) and of the healthy group (r = 0.63, 0.71, 0.63, 0.63, and 0.74), respectively. The median HRV indexes of the AMI group on the 2nd and 7th day differed from the healthy group (P < 0.05): RMSSD = 10.37, 19.95, 24.81; RMSM = 23.47, 31.96, 43.79; LFnu = 0.79, 0.79, 0.62; HFnu = 0.20, 0.20, 0.37; LF/HF ratio = 3.87, 3.94, 1.65; ApEn = 1.01, 1.24, 1.31, respectively. There was agreement between the methods, suggesting that these have the same power to evaluate autonomic modulation of HR in both AMI patients and healthy subjects. AMI contributed to a reduction in cardiac signal irregularity, higher sympathetic modulation and lower vagal modulation.

[Evaluation of an information document about patients and transfusion]. / Evaluation du document d'information des patients sur la transfusion.

OBJECTIVE: To evaluate the understanding of written information contained in the information sheet for patients intended to receive an homologous transfusion and to know their opinion about this document. TYPE OF THE STUDY: A prospective cohort survey carried out by people unrelated to clinical units and transfusion services. METHODS: A document divided in two parts, the first one summarized, the second detailed, was distributed to transfused adult patients. The patients were hospitalized in the general surgery and orthopedic wards of two hospitals and in the hematology and oncology wards of two different hospitals. A questionnaire was filled out in the presence of the inquirer. RESULTS: Sixty one subjects have been enrolled, among them 53 considered the information as adequate; 53 as comforting and neutral. 53 patients considered a written information as essential and 52 estimated that both part of the information sheet (summarized and detailed) were mandatory. Conversely, a more in depth investigation revealed there was a gap between patients statements and their true understanding. CONCLUSION: The value of a written information for the patients is confirmed by the study. In addition, patients were not generally worried by this information. The partition of the document has been appreciated. It is noteworthy that a gap exist between the patient's perception of the information and their actual level of understanding.

Leukocytosis due to adrenal metastases from malignant melanoma: reversal after bilateral adrenalectomy with long-term survival.

Leukocytosis has been noted in association with many non-hematologic malignancies in the absence of concurrent infection or metastatic involvement of bone marrow. We report a case of sustained, neutrophilic leukocytosis in a patient with disseminated malignant melanoma which reversed after bilateral adrenalectomy for adrenal metastases.

Acute non-lymphocytic leukemia (ANLL) following treatment with dacarbazine for malignant melanoma.

ANLL followed a brief period of aplastic anemia in a man treated intensively 4 years and 3 months previously with dacarbazine as "adjuvant" therapy for malignant melanoma. This is the first reported instance in which the latency between drug exposure and onset of leukemia strongly implicates dacarbazine as a leukemogenic agent.

Spigelian hernia.

Six cases of spigelian hernia are reported, including three unusual ones: (1) the presence of an acutely inflamed appendix in the hernial sac; (2) a patient with multiple associated hernias; and (3) a woman with a strangulated spigelian hernia occurring with endometrial carcinoma. The anatomy, etiology, clinical features and management of these hernias are discussed.
