Supply chain management maturity assessment: challenges of the enterprises in Serbia
Nowadays competition has been spread to supply chains, instead of individual enterprises. Therefore, beside evaluation of enterprise’s capabilities to manage business processes, it is important to assess capabilities for business process management at supply chain level. The purpose of the research presented in this paper is to point out the necessity of supply chain management maturity in implementation of best practice. Research methodology is based on supply chain management maturity models. Application of the Delphi method enabled usage of maturity model, adapted to the enterprises in Serbia. The value of the research precedes from unique combination of best practice elements for the assessment of supply chain management maturity level. The research results show that best practice elements are not very popular in the enterprises in Serbia. All enterprises are at the second and third maturity level. Bearing in mind that everything has to be improved continually, maturity models, proposed by different authors can be further developed by including certain statistical tools. The original contribution of this paper and its practical implication refer to including statistical tools, hierarchical cluster analysis and correlation, into maturity analysis, thus enabling creation of framework as a road-map for the improvement of supply chain management maturity
Complications of chronic necrotizing pulmonary aspergillosis: review of published case reports
Chronic necrotizing pulmonary aspergillosis (CNPA), a form of chronic pulmonary aspergillosis (CPA), affects immunocompetent or mildly immunocompromised persons with underlying pulmonary disease. These conditions are associated with high morbidity and mortality and often require long-term antifungal treatment. The long-term prognosis for patients with CNPA and the potential complications of CNPA have not been well documented. The aim of this study was to review published papers that report cases of CNPA complications and to highlight risk factors for development of CNPA. The complications in conjunction associated with CNPA are as follows: pseudomembranous necrotizing tracheobronchial aspergillosis, ankylosing spondylarthritis, pulmonary silicosis, acute respiratory distress syndrome, pulmonary Mycobacterium avium complex (MAC) disease, superinfection with Mycobacterium tuberculosis, and and pneumothorax. The diagnosis of CNPA is still a challenge. Culture and histologic examinations of bronchoscopically identified tracheobronchial mucus plugs and necrotic material should be performed in all immunocompromised individuals, even when the radiographic findings are unchanged. Early detection of intraluminal growth of Aspergillus and prompt antifungal therapy may facilitate the management of these patients and prevent development of complications
First reported case of fulminant TB with progression of infection from lungs to the genitourinary region
Although tuberculosis (TB) is a curable disease, it continues to be one of the leading infections associated with death in the world. Extra-pulmonary TB (EPTB) occurs in approximately 10% of the total cases, presenting with lymph nodes, pleura, bone and genitourinary tract as the most common locations. Genitourinary tuberculosis, the second most common EPTB, is very difficult to diagnose unless there is a high index of suspicion. Isolated TB orchitis or prostatitis without clinical evidence of renal involvement is a rare entity among genitourinary tuberculosis. We presented the first reported case of TB prostatitis and orchitis associated with pulmonary TB and the presence of an acute massive caseous pneumonia in an immunocompetent man. Despite the anti-TB therapy, the patient presented a rapid progression of disease and deterioration of general conditions taking to death, which occurred four days after TB treatment had started. Disseminated TB is a relatively uncommon cause of acute massive caseous pneumonia; however, there should always be suspicion of the disease, since it is a potentially treatable cause. This rare case supports the assertion that TB should be considered as an important differential diagnosis of genitourinary tumors irrespective of evidence of active TB elsewhere in the body
THE IMPORTANCE OF INFORMATION TECHNOLOGIES FOR AUTOMOTIVE CLUSTER OF THE REPUBLIC OF SERBIA
Enterprise networking occurs as a consequence of the globalization and the tendency to increase the ability to meet customer requirements. The functioning of networked enterprises as complex interorganizational networks in modern conditions is impossible without the implementation of appropriate information technology (IT). They provide stronger partnerships, fast and easier sharing of information, more transparency and less distorted information. The importance of the application of IT will be highlighted through the advantages of IT, as well as factors that may limit the process of their application. The analysis was conducted based on a sample of 28 enterprises which are the cluster members. The general conclusion based of the analysis is that there is a link among IT implementation and achievement of positive effects in certain business segments (Sharing information, Supply reliability, Inventory reduction, Cost reduction, Fast delivery, Product quality, Process continuity), which means that enterprises that have implemented IT generate positive effects in the observed fields. The analysis was performed by application of the following statistical tools: descriptive statistics, Fisher's exact probability test, correlation analysis and cluster analysis.Key Words: enterprise networking, information technology, automotive cluster, correlation analysis, cluster analysis
A Herbal Formula in the Therapy of Acute Postviral Rhinosinusitis
Objective:To assess the effects and adverse events of preparation Sinulan forte® containing extracts of five medicinal plants in comparison to mometasone furoate nasal spray (MFNS) in therapy of acute postviral rhinosinusitis (APRS).Methods:We included 46 APRS patients in this prospective investigation and randomized to two groups. The patients in group 1 (n=23) received MFNS 200 μg two times/day for ten days, and patients in group 2 (n=23) received Sinulan forte®, tablets 225 mg per os, two times/day also for ten days. We evaluated the total symptom score (TSS), the separate scores for individual symptoms (nasal congestion, rhinorrhea, postnasal discharge, facial pain, impaired sense of smell), the quality-of-life outcome, and the findings from nasal endoscopy (edema of the nasal mucosa, nasal secretion) prior and after the therapy.Results:Significantly lower absolute post-treatment scores and better relative improvement were identified for TSS, nasal congestion, facial pain, loss of the sense of smell, edema of the mucosa and nasal secretion in patients receiving herbal preparation (group 2). However, lower absolute post-treatment score and better relative improvement were found for rhinorrhea and postnasal drip in group 1. Clinically important differences were found regarding the TSS and endoscopic findings, with no adverse effects in group 2, but in group 1 two patients had mild nasal bleeding and two had sensation of dryness in the nasal mucosa.Conclusion:Herbal product Sinulan forte® can be a safe and effective treatment for APRS. Our results suggest no adverse events of this herbal preparation in comparison to intranasal corticosteroid spray therapy
Study toward resolving the controversy over the definition of allergic fungal rhinosinusitis
Dysbiosis of the microbiome on the airway mucosa leads to the development of chronic inflammatory and allergic disorders. The aim of this study was to consider the potential diagnostic criteria for allergic fungal rhinosinusitis (AFRS) and nonallergic fungal rhinosinusitis (FRS), and the role of fungal presence in an environment for the development of AFRS. In this study, 136 patients were divided into two groups: patients with positive specific immunoglobulin E (sIgE) and fungal finding (AFRS group), and patients with negative sIgE and positive fungal finding (FRS group). The study design included: anamnesis data, sIgE, eosinophil count and skin-prick test, rhinology and computerized tomography (CT) observation and mycological finding. Our results showed: (i) the prevalence in Serbia is: AFRS 1.3%, FRS 2.8%; (ii) 30.4% patients with sIgE+ had more often severe and recurrent chronic rhinosinusitis (CRS) (P = .005) and the presence of polyps (P = .025); (iii) 46.4% patients with sIgE+ had positive fungi on the sinonasal mucosa and were considered as AFRS; (iv) patients with AFRS had more frequent asthma (P = .024) and chronicity of CRS > 10 years (P = .000). The persistent fungal presence and prolonged duration of CRS could be a silent threat for the progression of inflammation and development of FRS. Lavage with hypertonic-NaCl should be included in the everyday hygiene routine in an effort to decrease fungal load and antigenic exposure. The presence of allergological parameters and better response to corticosteroid therapy in AFRS patients should be considered as crucial diagnostic criteria for AFRS
Proven invasive pulmonary mucormycosis successfully treated with amphotericin B and surgery in patient with acute myeloblastic leukemia: a case report
INTRODUCTION: Invasive mucormycosis (zygomycosis) is the third most frequent fungal infection in patients with hematologic malignancies. It often results in a fatal outcome mainly due to the difficulty of early diagnosis and its resistance to antimycotics. CASE PRESENTATION: A 52-year-old Caucasian man was diagnosed with acute myeloblastic leukemia. Following the induction chemotherapy he developed febrile neutropenia. Meropenem (3×1000mg/day) was introduced empirically. A chest computed tomography showed soft-tissue consolidation change in his right upper lobe. A bronchoscopy was performed and the histology indicated invasive pulmonary aspergillosis based on fungal hypha detection. Also, high risk patients are routinely screened for invasive fungal infections using commercially available serological enzyme-linked immunosorbent assay tests: galactomannan and mannan (Bio-Rad, France), as well as anti-Aspergillus immunoglobulin G and/or immunoglobulin M and anti-Candida immunoglobulin G and/or immunoglobulin M antibodies (Virion-Serion, Germany). Galactomannan showed low positivity and voriconazole therapy (2×400mg/first day; 2×300mg/following days) was implemented. The patient became afebrile and a partial remission of disease was established. After 2 months, the patient developed a fever and a chest multi-slice computed tomography showed soft-tissue mass compressing his upper right bronchus. Voriconazole (2×400mg/first day; 2×300mg/following days) was reintroduced and bronchoscopy was repeated. Histologic examination of the new specimen was done, as well as a revision of the earlier samples in the reference laboratory and the diagnosis was switched to invasive pulmonary mucormycosis. The treatment was changed to amphotericin B colloidal dispersion (1×400mg/day). The complete remission of acute myeloblastic leukemia was verified after 2 months. During his immunerestitution, a high positivity of the anti-Aspergillus immunoglobulin M antibodies was found in a single serum sample and pulmonary radiography was unchanged. A lobectomy of his right upper pulmonary lobe was done and the mycology culture of the lung tissue sample revealed Rhizopus oryzae. He remained in complete remission for more than 1 year. CONCLUSIONS: Invasive mucormycosis was successfully treated with amphotericin B, surgery and secondary itraconazole prophylaxis. As a rare disease invasive mucormycosis is not well understood by the medical community and therefore an improvement of education about prevention, diagnosis and treatment of invasive mucormycosis is necessary
An exceptional case report of disseminated cryptococcosis in a hitherto immunocompetent patient
Cryptococcosis is an opportunistic fungal infection causes significant disease predominantly in immunocompromised patients. Here we present an excepcional case of disseminated cryptococcosis with pulmonary and cerebral involvement in an immunocompetent patient with no apparent predisposing factors at the time of hospital admission. We described a case of an apparently immunocompetent 66-years old man admitted to hospital with a one-month history of cough, fever and vertigo. During hospitalization, thorax imaging was suggestive of lung metastasis, therefore, he went through several investigations. During hospitalization, he developed neurological symptoms and subsequently underwent a lumbar puncture. Cerebrospinal fluid (CSF) culture was positive for Cryptococcus spp. isolated on Sabouraud’s dextrose agar and bird seed agar. In addition, the direct microscopy examination was positive for the India ink test, as well as with the latex agglutination test for cryptococcal polysaccharide antigen (CrAg) in CSF, while serum CrAg was negative. Despite the absence of classic immunocompromising features, he was treated with amphotericin B and fluconazole due to suspected disseminated cryptococcal infection. Later, he was diagnosed with prostatic adenocarcinoma. Upon successful completion of treatment for disseminated cryptococcosis, the patient underwent radical prostate ablation surgery as a treatment forprostatic adenocarcinoma. This exceptional case emphasizes the high degree of suspicion of atypical infections, and in these cases, it is particularly important to consider fungal infections in hitherto healthy patients with no apparent predisposing factors. Although Cryptococcus spp. is predominantly reported in patients with hematological malignancies, cryptococcosis investigation should also be considered as part of the initial workup of patients with a new diagnosis of a solid tumour prior to chemotherapy or radiotherapy.Publisher PDFPeer reviewe
Prevention of polymicrobial biofilms composed of Pseudomonas aeruginosa and pathogenic fungi by essential oils from selected Citrus species
Mixed microbial infections caused by Pseudomonas aeruginosa and pathogenic fungi are commonly found in patients with chronic infections and constitute a significant health care burden. The aim of this study was to address the potential polymicrobial antibiofilm activity of pompia and grapefruit essential oils (EOs). The mechanism of antimicrobial activity of EOs was analysed. EOs of pompia and grapefruit inhibited fungal growth with MIC concentrations between 50 and 250 mg L-1, whereas no effect on P. aeruginosa growth was observed. Both citrus EOs inhibited formation of bacterial and fungal monomicrobial biofilms in concentrations of 50 mg L-1 and were efficient in potentiating the activity of clinically used antimicrobials in vitro. The concentration of 10 mg L-1 EOs inhibited mixed biofilm formation composed of P. aeruginosa and Aspergillus fumigatus or Scedosporium apiospermum. Citrus EOs affected quorum sensing in P. aeruginosa and caused fast permeabilisation of Candida albicans membrane. Pompia and grapefruit EOs potently inhibited biofilm formation and could be used for the control of common polymicrobial infections
Stress and life satisfaction among alcohol addicts
Objective. The aim of the study was to determine the level of stress and life satisfaction in alcohol addicts, i.e., to examine whether respondents diagnosed with alcohol dependence (F10.2) differ according to the level ofstress and life satisfaction in comparison to respondents from the general population. Methods. The research was designed as a non-experimental, observational cross-sectional study, and was conducted in the period from January to July 2021, at the University Clinical Center Kragujevac. The sample consisted of 80 subjects of both sexes, aged 22 to 36 years, divided into two groups: the clinical group (subjects diagnosed with alcohol dependence - F10.2) and the control group of subjects without psychiatric illness. Results. The study has shown that alcohol addicts have clinically significant and severe symptoms of stress, as well as that stress symptoms were positively correlated with alcoholism, and negatively with life satisfaction. In our sample, the association between stress and life satisfaction in addicts was very negative and very significant (r = - 0.645, p <0.001). In the clinical group of alcohol addicts, a very strong correlation was found (r = - 0.907, p <0.001), while in the control group there was a moderate correlation (r = - 0.315, p <0.05). No statistically significant correlation of stress was found with marital status, as well as with work status, level of education or religious beliefs. Conclusion. In our study, it was found that higher values of stress and lower values of life satisfaction are predictive values for the possibility of alcohol dependence. These findings can be used as an auxiliary tool for orientation assessment as part of establishing the diagnosis of alcohol dependence, as well as for a better understanding of the stress phenomenon in the clinical population of alcohol addicts in our country.Publishe
