ABSTRACT
Population aging is a global phenomenon. Each country in the world faces an increased number of older persons in the total population. With aging, a high prevalence of multiple chronic diseases occurs, leading to the use of complex therapeutic regimens and often to polypharmacy. Potentially inappropriate medication (PIM) is a medicine prescribed to a patient for whom the risks outweigh the benefits. Today, several tools are used to evaluate the use of pharmacotherapy in older adults, one of them is the 2019 AGS Beers Criteria. In this prospective, pilot study, we aimed to investigate if the number of PIMs in elderly patients would be significantly reduced if a clinical pharmacist performed a pharmacotherapy review. The study included 66 patients over 65 years of age who were hospitalized at the 1200-bed university hospital. The intervention was conducted by a clinical pharmacist who reviewed the patients' pharmacotherapy and provided written suggestions to physicians. The pharmacotherapy was again reviewed at the patients' discharge from the hospital. A total number of 204 PIMs were identified in the pharmacotherapy of the study population. At discharge, the number of PIMs decreased to 67. A total of 67% of the pharmacist's suggestions were accepted by the physicians. The pharmacist's intervention led to significant decrease in the number of PIMs on patients' discharge letters.
ABSTRACT
In an ongoing multinational trial, we obtained blood samples from 365 volunteers vaccinated with mRNA vaccines (Moderna, BioNTech), viral DNA-vectored vaccines (AstraZeneca, Sputnik-V, and Johnson and Johnson), or the attenuated virus vaccine from Sinopharm. After collecting reactogenicity data, the expression of S-Protein binding IgG and IgA was analyzed using an automated sandwich ELISA system. Serum neutralizing potentials were then investigated using an ACE-2-RBD neutralizing assay. Moderna's vaccine induced the highest amounts of SARS-CoV-2 specific neutralizing antibodies compared to the other groups. In contrast, Sinopharm and Johnson and Johnson's vaccinees presented the lowest SARS-CoV-2-specific antibody titers. Interestingly, moderate to high negative correlations between age and virus-specific IgG expression were observed in the Johnson and Johnson (ρ =-0.3936) and Sinopharm (ρ =-0.6977) groups according to Spearman's rank correlation analysis. A negative correlation was seen between age and IgA expression in the Sputnik-V group (ρ =-0.3917). The analysis of virus neutralization potentials in age categories demonstrated that no significant neutralization potential was observed in older vaccinees (61and 80 years old) in the Sputnik-V Johnson and Johnson and Sinopharm vaccinees' groups. In contrast, neutralization potentials in sera of Moderna, BioNTech, and AstraZeneca vaccinees were statistically comparable in all age categories. Furthermore, while the AstraZeneca vaccine alone induced moderate IgG and IgA expression, the combination with Moderna or BioNTech mRNA vaccines induced significantly higher antibody levels than a double dose of AstraZeneca and similar IgG expression and neutralization potential compared to Moderna or BioNTech vaccines used alone. These results suggest that mRNA vaccines are the most immunogenic after two doses. DNA vectored vaccines from AstraZeneca and Sputnik-V presented lower but significant antibody expression and virus neutralizing properties after two doses. The lowest antibody and neutralization potential were observed in the Sinopharm or Johnson and Johnson vaccinees. Especially elderly over 60 presented no significant increase in neutralizing antibodies after vaccination. The data also indicate that heterologous vaccination strategies combining the AstraZeneca DNA vectored vaccines and mRNA vaccines are more effective in the induction of neutralizing antibodies compared to their homologous counterparts.

OBJECTIVE: To identify the type of the non-invasive ventilatory treatment for patients diagnosed with chronic obstructive pulmonary disease (COPD), with respiratory status deteriorated by COVID-19 pneumonia, and in need of treatment in the Intensive Care Unit (ICU). MATERIALS AND METHODS: This cross-sectional study was conducted over a one-year period in the medical intensive care units of two hospitals. As the patients' clinical condition deteriorated and the parameters of the arterial blood gas (ABG) analysis worsened, oxygen support was applied via a high flow nasal cannula (HFNC) or by non-invasive positive pressure ventilation (NPPV). According to the control values of the arterial oxygen saturation (SaO2) and the parameters of ABG, the patients were enabled to be transferred between the two types of non-invasive ventilatory support. The primary outcome was the length of hospital stay, while secondary outcomes were the rate of intubation, the mortality rate, and respiratory supportfree days. RESULTS: Out of 21 critical patients with COPD and COVID-19, 11 (52.4%) were initially treated with NPPV and 10 (47.6%) with HFNC. The ages (67±9.79 in NPPV group vs. 70.10±10.25 in HFNC group) and severity of illness (SOFA score 5 (3.5) in NPPV group vs. 5 (2.8) in HFNC group) were similar between the two groups. Switching the mode of respiratory support was more common in NPPV (58.3% in survivor group vs. 41.7% in non-survivor group). Patients treated with NPPV compared to HFNC had a nominally longer length of stay (15 (11) vs. 11.5 (4.25)), and higher risk of intubation (66.7% vs. 33.3%) and mortality (66.7% vs. 33.3%), but the comparisons did not reach statistical significance. Survivors had significantly longer Medical Intensive Care Unit and hospital stays, but significantly lower FiO2 (0.60 vs.1) and higher values of PaO2/FiO2 (78(32.4) vs. 56.3(17.8)) than non-survivors. All patients were treated with corticosteroids, and the duration of treatment was similar between groups. CONCLUSION: In critically ill patients with COPD and COVID-19, both HFNC and NPPV were commonly used as the initial mode of ventilation. Switching to a different mode and adverse patient outcomes were more frequent in patients initially treated with NPPV. Survivors had higher values of PaO2/FiO2 than non-survivors.

The early diagnosis of metastatic pulmonary calcification is beneficial, as some patients may develop restrictive changes in respiratory function or in some cases lethal acute respiratory distress. The aim of the study was to evaluate whether scanning with 99(m)Tc DPD might be useful in early diagnosis of pulmonary calcification in setting of chronic renal failure and hemodialysis and if presence of pulmonary calcification is associated with an abnormality in respiratory parameters. Forty-two patients with end-stage renal disease, who were treated by regular haemodialysis, were investigated. Twenty five (59.5%) out of forty two patients had increased lung uptake of 99(m)Tc DPD at whole body scintigraphy-grade 2 group. These patients were on dialysis 149±26 months compared with 57±16 months in 17 patients with a normal lung uptake of 99(m)Tc DPD at whole body scintigraphy- grade 1 group (p<0.01). In grade 2 group 22 patients (88%) had significantly lower (p<0.01) parameters of spirometry (FEF25-75, FEF75 FEF50, FEF25) compared to predicted values while in grade 1 group the parameters were significantly lower in only six patients (35.3%). There was statistically insignificant difference between these two groups regarding parathyroid hormone level (p>0.05). These observations confirm previous findings that scintigraphy with 99(m)Tc DPD may be efficious in early diagnosis of pulmonary calcification in hemodialised patients as well as the fact that spirometry is useful in patients with confirmed pulmonary calcifications.

The aim of this study was to asses the accuracy of 99mTc-sestamibi scintimammography in patients with suspected recurrent breast cancer in the breast or loco regional tissues. After routine analyses in twenty-eight women (clinical examination, ultrasound, X-ray mammography, and fine needle aspiration biopsy) they were examined by scintimammography. All patients with suspected recurrent cancer in the breast or loco regional tissues (19) undergone surgery and the final diagnosis was determined by histopathological examination. Another 9 patients were followed 6-24 months. The scintigraphic studies were correlated with radiological findings and/or with histopathology. There were 19 patients with recurrent tumours (15 with loco-regional recurrent and 4 in another breast). X-ray mammography identified 13 of these cancers. 99mTc-sestamibi scintimammography identified seventeen of recurrent breast cancers. In the seven out of nine patients without cancer, scintimammography were reported as having no changes consistent with cancer. X-ray mammography showed suspected cancer lesions in four out of nine patients without cancer. There were two false-positive scintimammograms and one false negative. Axillary lymph node recurrence occurred in four patients. All of them were positive on scintimammography. 99mTc-sestamibi scintimammography showed higher sensitivity, specificity and accuracy per patient than did X-ray mammography (90,9% vs. 63,6%, 71,4% vs. 57,1% and 83,3% vs. 61,1%, respectively). To identifying recurrent breast cancer disease is better to use scintimammography than X-ray mammography.

INTRODUCTION: The present study deals with anaerobic power capacity in athletes, differences between power capabilities of these athletes in relation to the type of sports and differences in regard to nonathletes. The goal of this study was to analyze parameters of anaerobic capacity and also to examine if the type and duration of the training period affect values of anaerobic capacity. MATERIAL AND METHODS: This study included 95 male subjects: non-athletes and athletes of various sports: judo players, rowers and soccer players. Anaerobic capacity was determined using the Wingate test. RESULTS AND DISCUSSION: The obtained results show a statistically higher anaerobic capacity in judo players (PP 798 W - 9.64 W/kg) in regard to soccer players (PP 763 W - 9.75 W/kg), rowers (PP 691 W - 8.8 4 W/kg) and non-athletes (PP 557 W - 6.93 W/kg). Judo is a sport which requires high anaerobic capacity. Our results show that athletes have a higher anaerobic power capacity in regard to non-athletes. It can be explained solely by physical training. athletes

Uremic lung is different entity then oedema present in cardiovascular diseases or in adult respiratory distress syndrome as well. This state is one of the possible complications in patients with chronic renal failure (CRF) receiving regular hemodialysis (HD). There are several studies suggesting that in these patients in 30-40% cases pulmonary hypertension was developed. It is known that patients with primary pulmonary hypertension have peripheral airway obstruction The data also showed that primary as well secondary pulmonary hypertension are more often developed in females; even real reason is still unknown. The aim of the study was to estimate the ventilator function improvement in patients with CRF receiving regular HD related to sex differences. The study population consisted in 39 patients with CRF, with no cardiac and pulmonary diseases. These patients were treated by regular hemodialysis using bicarbonate or acetate mode, respectively. They were divided into two groups according to the sex. Spirometry parameters before and after onset of hemodialysis were recorded. The results were analyzed using Student t-test and presented as mean +/-SD. All p values <0,05 were considered significant. The result showed that ventilatory function in male patients is significantly improved, especially VC and FEV1, whereas in female patients improvement had not statistical significance. It can be concluded that one of the possible reasons for slight improvement of ventilator function in female patients is pulmonary hypertension.
