Pretreatment detection of peripheral blood malignant circulating plasma cells (CPCs) has been shown to be of negative prognostic value in multiple myeloma (MM). We hypothesized that the assessment of CPC kinetics in response to one therapy cycle using six-color flow cytometry could be helpful in the early detection of MM refractoriness to treatment. Forty-two patients with refractory or relapsed (RR) MM were enrolled. Median time to tumor progression (TTP) of 51 days and median overall survival (OS) of 308 days was shortest in patients whose CPCs with aberrant phentoype (aCPCs) did not decrease after one therapy cycle compared to patients with decreasing (median TTP 258 days and OS 856 days) or undetectable (median TTP 581 days and OS 1006 days) aCPCs (p < 0.001 and p = 0.007 for TTP and OS, respectively). Non-reduction of aCPCs in patients with RR MM after the first cycle of therapy may be useful in early identification of patients resistant to a given therapy.

This study evaluated the efficacy and safety of dose-dense high-dose methylprednisolone (HDMP) plus rituximab (Rtx) in patients with high-risk CLL. Twenty-nine patients with relapsed or progressive CLL with adverse cytogenetics (17p deletion, TP53 mutation, 11q deletion, and/or trisomy 12) and/or progression within 12 months of fludarabine treatment were included. HDMP (1 g/m(2)) was administered daily for 5 days of each treatment course. Rtx was administered on days 1 (375 mg/m(2)) and 5 (500 mg/m(2)) of the first treatment course, on days 1 (500 mg/m(2)) and 5 (500 mg/m(2)) of the second course, and on day 1 (500 mg/m(2)) of courses 3-6. The cycles were repeated every 21 days. The overall response rate (ORR) was 62%, and 28% of patients had stable disease. In 13 patients with 17p deletion/TP53 mutation, ORR was 69%. After 22 months, the median progression-free and overall survivals were 12 and 31 months, respectively. The most frequent toxicity was hyperglycemia, and three deaths occurred in the study. Dose-dense treatment with HDMP and Rtx is an effective therapy with a favorable safety profile in patients with high-risk CLL, including those with 17p deletion/TP53 mutation.

Background & aimsEven though malnutrition is frequently observed in cardiac population outcome data after cardiac surgery in malnourished patients is very rare. No thorough research was done concerning the impact of malnutrition on neuropsychological outcomes after cardiac surgery. The aim of our study was to analyze the incidence of postoperative delirium development in malnourished patients undergoing on pump bypass grafting.MethodsWe performed a cohort study of adults admitted to Vilnius University Hospital Santariskiu Clinics for elective coronary artery bypass grafting. The nutritional status of the patients was assessed by Nutritional Risk Screening 2002 (NRS-2002) questionnaire the day before surgery. Patients were considered as having no risk of malnutrition when NRS-2002 score was less than 3 and at risk of malnutrition when NRS-2002 score was ≥3. During ICU stay patients were screened for postoperative delirium development using the CAM-ICU method. and divided into two groups: delirium and non delirium. The statistical analysis was preformed to evaluate the differences between the two independent groups. The logistic regression model was used to evaluate the potential preoperative and intraoperative risk factors of postoperative delirium.ResultsNinety-nine patients were enrolled in the study. Preoperative risk of malnutrition was detected in 24 % (n = 24) of the patients. The incidence of early postoperative delirium in overall study population was 8.0 % (n = 8). The incidence of the patients at risk of malnutrition was significantly higher in the delirium group (5 (62.5 %) vs 19 (20.9 %), p <0.0191). In multivariate logistic regression analysis risk of malnutrition defined by NRS 2002 was an independent preoperative and intraoperative risk factor of postoperative delirium after coronary artery bypass grafting (OR: 6.316, 95 % CI: 1.384-28.819 p = 0.0173).ConclusionsPreoperative malnutrition is common in patients undergoing elective coronary artery bypass grafting. Nutrition deprivation is associated with early postoperative delirium after on pump coronary artery bypass grafting.

Background and objective: According to the World Health Organization (WHO), more than 100 million people have already recovered from SARS-CoV-2 infection. Therefore, it is imperative to understand the possible outcomes of COVID-19. The aim of our study was to evaluate pulmonary function, exercise capacity, residual radiological changes, and health-related quality of life (HRQoL) at follow-up in a cohort of SARS-CoV-2 pneumonia survivors. Materials and Methods: Patients with SARS-CoV-2 infection and radiologically confirmed lung injury, with no chronic lung disease prior to this infection, were included in the study. Patients’ evaluation 2 months after their discharge from hospital included spirometry (FVC, FEV1, FEV1/FVC), determination of lung volume (TLC, VC, RV) and diffusing capacity of lung for carbon monoxide (DLCO, adjusted for hemoglobin), 6-Minute Walk Test (6MWT), chest CT scan, and 36-Item Short Form General Health Survey (SF-36). Results: Fifty-one patients (25 men, 26 women) were included. The mean age was 56 years (SD-11,72). Eighteen patients (35.3%) had experienced moderate COVID-19, 21 (41.2%) severe COVID-19, and 12 (23.5%) were critically ill. The mean follow-up visit time after the discharge from hospital was 60 days (SD-17). Pulmonary function at follow-up was impaired in 24 (47.2%) patients. Reduced lung volume was observed in 15 (29.4%) patients, DLCO reduction in 15 (29.4%) patients, and only one patient displayed obstruction. Twelve patients out of 51 (12/51, 27.3%) showed reduced physical capacity in the 6 MWT, and 3/51 (9.1%) showed desaturation, with SO2 < 90%. Different levels of abnormality were found in 49/51 (96,1%) patients on follow-up chest CT; the median radiological score was 10.9 (SD ± 8.87, possible maximal score, 25). Ground-glass opacity was the most common radiological feature, found in 45 (88.2%) patients. The SF-36 scores demonstrated a reduction in health status across all domains, with the lowest scores for limitations in social activities because of physical problems, vitality, and general health. Conclusion: In the group of COVID-19 pneumonia survivors 2 months after hospital discharge, residual changes in the lungs on chest CT and in lung function and reduced physical and HRQoL status were found in a significant number of patients. To evaluate COVID-19 long-term consequences, a longer follow-up period is needed.
