Physiotherapy & Psychosocial Rehabilitation in Postcovid & Postconflict Era: New Roles with same Staff? (dispatch)

Waves of COVID-19 have been managed successfully within US, EU, Southeast Asia and Latin America, however, South Asia and Sub-saharan Africa still suffer new variants and EU fights with UK and United States of ,,new waves of old disease“, postcovide or long covide syndrome. The aim of this communication and research is to prepare our auditors for the size and extent of postcovid systems and the importance of non-doctors and non-medicine experts in management of its consequences.

Etiology and Risk Factors of 339 Cases of Infective Endocarditis: Report from a 10-year National Prospective Survey in the Slovak Republic

The authors studied the etiology, outcome and risk factors of 339 cases of infective endocarditis (IE) in Slovakia over the last 10 years. Aortic valve was infected in 59.9%, mitral in 38.1% and tricuspidal/pulmonary in 5.0% of cases. The majority of IE were caused by staphylococci (29.2%), 15.0% were due to viridans streptococci, 7.4% due to Enterococcus faecalis, 3.9% due to the HACEK group (Haemophilus spp., Actinobacillus spp., Corynebacterium spp., Eikenella spp., Kingella spp.) and 39.2% were culture negative. The following risk factors were the most frequently identified: rheumatic fever in 24.2%, dental surgery in 13.3%, previous cardiosurgery in 7.1% and neoplasia in 7.1%. All patients were treated with antimicrobials and 42.5% of patients also with surgery (valvular prosthesis replacement): 61 (18.0%) died, and 278 (82.0%) survived at day 60 after the diagnosis of endocarditis was made. Univariate analysis did not show significant differences in most of the recorded risk factors between patients who died and those who survived: apart from staphylococcal etiology (44.3% vs. 26.6%, P < 0.01), persistent bacteremia (with three or more positive blood cultures 24.6% vs. 9.7% P < 0.002) which were significantly associated with higher attributable mortality, as was absence of surgery (55.7% vs. 6.1% P < 0.001), whereas antibiotic therapy in combination with surgery significantly predicted better outcome (P < 0.001). We compared risk factors, etiology, therapeutic strategies and outcome of IE in two periods: from 1991-1997 (180 cases) and from 1998-2001 (159 cases). Rheumatic fever was less commonly observed in second period (1998-2001) P < 0.01 since its prevalence in Slovakia is rapidly decreasing. Dental surgery was less frequent as well (20.5% vs. 5.0% P < 0.001). There was a significant shift in etiology within the second study period: negative-culture endocarditis (despite better bacteriological techniques) (P < 0.001) was more frequently observed in the 1st period and represented 53.3% of all cases in 1998-2001 in comparison to 26.7% in 1991-1997. Enterococci (P < 0.0002) were also more frequent in the 2nd period. Persistent bacteremia (3 or more positive blood cultures 20.5% vs. 3.1%, P < 0.001 was less commonly observed within the 2nd period (1998-2001) in comparison to 1991-1997. More patients in the second period (1998-2001) had complications of IE (P < 0.001) than in the 1st period. However mortality was lower (22.2% vs. 13.2%, P < 0.044) because of more surgical intervention in the 2nd period (52.8% vs. 33.3%, P < 0.001).

Prospective national survey of viridans streptococcal bacteraemia risk factors, antibacterial susceptibility and outcome of 120 episodes

The aim of this study was to prospectively investigate 120 cases of viridans streptococcal bacteraemia (VSB) in 117 patients in major university hospitals in Slovakia in 2000-2002 (3 y) for antibacterial susceptibility, risk factors and outcome. From 127 episodes, 16 (13%) of VSB were caused by PEN-R strains and 13 (10%) by ERY-R strains. 32 cases had cancer as underlying disease (20 haematological), 41 had endocarditis and 35 were elderly (>65 y of age) patients. Concerning mortality, 29 of 127 patients died (24%). There were several risk factors associated with mortality. Solid tumour as underlying disease (p<0.02), stroke (p<0.002), concomitant lung infection (p<0.01), endoscopic procedure (p<0.036), intubation (p<0.0008), ventilatory support (p<0.002), and coma (p<0.009) were associated with more deaths. A comparison of 115 bacteraemias to 13 bacteraemias caused by erythromycin-resistant strains of Streptococcus viridans was performed. There were no significant differences in underlying disease, risk factors and mortality. Erythromycin resistance in bacteraemias caused by S. viridans did not have significant impact on outcome of the patients, nor did it show specific relation to analysed risk factors in our study. 14.5% of VSB were cause by PEN-resistant viridans streptococci. Risk factors for penicillin resistance were ventilatory support (p<0.01), intubation (p<0.001) and resistance to other antibiotics: 8 of 16 (50%) of PEN-R VSB were resistant also to erythromycin or cotrimoxazole or tetracycline compared with 9% of PEN-R VSB (p<0.005). Endoscopic procedures in the upper respiratory system were at risk for development of PEN-R VSB. There was also difference in outcome; 71% vs 22.5% (p<0.0002) of cases infected with PEN-R VSB died compared to PEN-S VSB. PEN-R is therefore clinically significant in VSB.

Standardization of measles, mumps and rubella assays to enable comparisons of seroprevalence data across 21 European countries and Australia

The aim of the European Sero-Epidemiology Network is to establish comparability of the serological surveillance of vaccine-preventable diseases in Europe. The designated reference laboratory (RL) for measles, mumps, rubella (MMR) prepared and tested a panel of 151 sera by the reference enzyme immunoassay (rEIA). Laboratories in 21 countries tested the panel for antibodies against MMR using their usual assay (a total of 16 different EIAs) and the results were plotted against the reference results in order to obtain equations for the standardization of national serum surveys. The RL also tested the panel by the plaque neutralization test (PNT). Large differences in qualitative results were found compared to the RL. Well-fitting standardization equations with R2> or =0.8 were obtained for almost all laboratories through regression of the quantitative results against those of the RL. When compared to PNT, the rEIA had a sensitivity of 95.3%, 92.8% and 100% and a specificity of 100%, 87.1% and 92.8% for measles, mumps and rubella, respectively. The need for standardization was highlighted by substantial inter-country differences. Standardization was successful and the selected standardization equations allowed the conversion of local serological results into common units and enabled direct comparison of seroprevalence data of the participating countries.

Nosocomial meningitis caused by Staphylococcus other than S. aureus in children: multicentre study

Analysing 101 cases of nosocomial meningitis due to staphylococci other than S. aureus within last 15 years, coagulase negative staphylococci represented the commonest pathogen. Major risk factor for staphylococcal meningitis was prior neurosurgery, mainly ventriculoperitoneal shunt insertion. Ten of 101 cases were caused by glycopeptide intermediate resistant strains in patients pretreated with multiple combination of antibiotics including vancomycin and shunt exchanges: 76% of strains were also oxacillin resistant.

Bacteremia due to Pseudomonas aeruginosa: results from a 3-year national study in the Slovak Republic

Risk factors, mortality and antimicrobial susceptibility of Pseudomonas aeruginosa bacteremias isolated from 148 patients from all University Hospitals in Slovakia were analyzed. Only 1.2% of 169 strains of P. aeruginosa were resistant to meropenem, 4.1% to piperacillin/tazobactam, 7.7% to ceftazidime as well as cefepime and 12% to amikacin. More than 30% of P. aeruginosa were resistant to ciprofloxacin. Our analysis of risk factors for antimicrobial resistance to the particular antimicrobials, indicated no difference in risk factors and outcome in cases infected with P. aeruginosa bacteremias resistant to amikacin, piperacillin/tazobactam or ceftazidime in comparison to episodes caused by P. aeruginosa due to susceptible isolates. When comparing risk factors for P. aeruginosa bacteremia in children vs. adults, cancer vs. non-cancer patients, several differences in risk factors were observed. Neither antimicrobial resistance to amikacin, ceftazidime or piperacillin/tazobactam, nor appropriateness of therapy according to two separate analyses were associated with better outcome.

Breakthrough fungaemia in neonates and infants caused by Candida albicans and Candida parapsilosis susceptible to fluconazole in vitro

Breakthrough fungaemias due to Candida albicans and Candida parapsilosis appearing during fluconazole therapy in neonates and infants were assessed for risk factors and outcome. Forty fungaemias occurred during therapy with fluconazole within a 12 year national survey and were compared with 161 cases of non-breakthrough paediatric fungaemias. The agar disc diffusion test method was used for antifungal susceptibility testing and the Vitek system for species identification. Univariate and multivariate analysis for risk factors for breakthrough fungaemia were carried out. All the fungaemias were a result of strains susceptible to fluconazole at 0.25-4 mg/L in vitro [C. albicans (85%) and C. parapsilosis (15%)]. The mean number of positive blood cultures per episode was 2.2. Sixteen children had 'early' breakthrough fungaemias (within 4-5 days) and 24 fungaemias appeared on day 6 and later. Mean fluconazole MICs in the 'early' group were 1.2, and 2.8 mg/L in the 'late' group (P < 0.03, t-test). However, no difference was observed in the average dose of fluconazole used in the two groups. Neonatal age, total parenteral nutrition, very low birth weight, before surgery, central or umbilical venous catheterization and artificial ventilation were all significantly related to breakthrough fungaemia in univariate analysis but only central or umbilical venous catheterization were significant in multivariate analysis. The outcome of breakthrough fungaemia was better overall and attributable mortalities in non-breakthrough fungaemia was significantly higher in comparison with breakthrough fungaemia.

Fungemia in cancer patients undergoing chemotherapy versus surgery: risk factors, etiology and outcome

26 patients with fungemia and cancer treated with chemotherapy (group A) were compared to 25 patients with fungemia and cancer treated with surgery (group B), to assess differences in etiology, risk factors and outcome. Candida albicans was responsible for 42% of fungemias in group A, and for 92% of fungemias in group B (p < 0.005). Breakthrough fungemia occurring during antifungal prophylaxis appeared in 46.6% of group A vs 12% of group B (p < 0.02). There was significant difference in outcome between the groups: 20% of patients after surgery vs 7.7% of those after chemotherapy died from fungemia (p < 0.04). Most common risk factors recorded in both groups were catheter insertion and previous therapy with broad spectrum antibiotics.

Nosocomial candidaemias due to species other than Candida albicans in cancer patients. Aetiology, risk factors, and outcome of 45 episodes within 10 years in a single cancer institution

Forty-five cases of fungaemia due non-albicans Candida spp. (NAC) in a single National Cancer Institution within 10 years were analysed for aetiology, risk factors and outcome. There had been 12 cases of fungaemia that were due to C. krusei, 14 due to C. parapsilosis, 7 due to C. (T.) glabrata, 6 to C. tropicalis, 2 to C. guillermondii, 2 to C. lusitaniae, 1 to C. stellatoidea, and 1 to C. rugosa. Comparison of 45 NAC fungaemia with 75 episodes of C. albicans fungaemia revealed differences only in two risk factors: previous empiric therapy with amphotericin B (16.0 vs 2.2%, P<0.01) appeared more frequently in cases of C. albicans fungaemia, and prior prophylaxis with fluconazole (8.9 vs 0%, P<0.02) was conversely more frequently observed with NAC. The incidence of other risk factors, such as underlying disease, chemotherapy, antibiotic prophylaxis or therapy, treatment with corticosteroids, catheter insertion, mucositis, cytotoxic chemotherapy, and neutropenia, was similar in both groups. There was no difference either in attributable or in overall mortality between NAC and C. albicans fungaemia in our cancer patients.

Comparative investigation of the long non-coding M-F genome region of wild-type and vaccine measles viruses

The sequence of the 300 nucleotides region of the measles virus genome was determined that includes a part of the 3'-untranslated region of the matrix (M) gene, the intergenic region and a part of the 5'-untranslated region of the fusion (F) gene [M-F region] for vaccine strain Leningrad-16 and 14 wild-type isolates. The data obtained demonstrate the variability of this long non-coding M-F region. No mutations in this region of the genome were found which seem to be specific for vaccine strains of measles virus (MV).

Analysis of 553 episodes of monomicrobial bacteraemia in cancer patients: any association between risk factors and outcome to particular pathogen?

Relationships between aetiology, various risk factors (such as neutropenia, catheter insertion, endoscopy, therapy with corticosteroids, therapeutic use of antimicrobials, antibiotic prophylaxis, source of infection), symptomatology and outcome were studied in 553 monomicrobial bacteraemic episodes in cancer patients observed within 7 years at the National Cancer Institute of the Slovak Republic. The ratio of gram-positive to gram-negative bacteraemia was 1:1 (43.5% vs 43.8%), and yeasts caused 7.2% of monomicrobial episodes. The highest mortality was associated with Pseudomonas aeruginosa (19.2%), non-albicans Candida yeasts (25%) and Bacteroides fragilis (22.6%). Independent risk factors for particular pathogens were investigated by a computerized logistic regression model. The only independent risk factor for staphylococcal and enterococcal bacteraemia was vascular catheter insertion (OR = 1.95 and 2.05, CI = 95%, P = 0.035 and 0.044, respectively). However, there were no independent specific risk significant factors for viridans streptococcal bacteraemia and bacteraemia due to Enterobacteriaceae or Ps. aeruginosa. Neutropenia was found to be an independent predictor for development of Acinetobacter spp. bacteraemia (OR = 3.84, CI = 95%, P = 0.044). Prior therapy with third-generation cephalosporines was a predictive, independent risk factor for the development of fungaemia (OR = 1.99, CI = 95%, P = 0.028) but not of enterococcal bacteraemia. We also did not observe any association between prior therapy with imipenem and Stenotrophomonas maltophilia bacteraemias. Multivariate analysis confirmed that fungaemia may be independently associated with higher mortality than bacteraemia caused by Enterobacteriaceae and staphylococci. However, the mortality of fungaemia was statistically no different from that of Ps. aeruginosa, Stenotrophomonas spp. and viridans streptococci bacteraemias.

[Immunoglobulin specific and conventional methods in the serodiagnosis of measles]

The serological diagnostics of suspicions of measles is of ever growing importance with adequately decreasing morbidity. The utilization of the complement binding reaction is compared with results of the haemagglutination test, the IgG enzyme immunoassay, the IgG and IgM immunofluorescence technique and the haemadsorption immunosorbent test for IgM prove of measles. The virus-specific methods of evidence prove to be favourable ones. The present possibilities of the decentralized routine diagnostics in district laboratories make the complement binding reaction a reliable method.
