Abstract We would like to demonstrate the difficulty of treatment in a patient after kidney transplantation (KTX) who developed chronic urinary tract infection (UTI) with a multi‐drug resistant ESBL‐producing Klebsiella pneumoniae . The patient underwent several treatment interventions including supportive therapy with bacteriophages. This article presents a case of a 60‐year‐old patient after KTX repeatedly admitted to the hospital with recurrent UTIs caused by ESBL‐producing Klebsiella pneumoniae showing variable susceptibility to carbapenems and full susceptibility to colistin only. KTX was performed due to renal insufficiency caused by polycystic kidney disease. The patient experienced 12 severe episodes of UTI due to K pneumoniae within 15 months since transplantation. In an attempt to curb the ongoing infections, phage therapy (PT) was applied on the experimental basis, coordinated by the Phage Therapy Unit of the Hirszfeld Institute in Wroclaw, Poland. Eventually, the patient fully recovered following nephrectomy of his own left kidney where cysts were the suspected reservoir of bacteria. The patient completed 29 days of PT. PT caused no reported side effects in the described case of the KTX recipient, although its role in controlling chronic UTI caused by K pneumoniae is unclear. More studies are needed in the population of kidney transplant recipients.
Antibiotic resistance (ABR) is at the top of global health threats. This paper aims to assess Polish physicians' readiness to impact ABR through prescribing routines.
Corynebacterium coyleae is part of the commensal microflora of the skin, urethra, mucous membranes, and genital tract. Isolates from patients with urinary tract infection (UTI) were reported, but the pathogenic potential of this species has not been defined yet. The aim of the study is to determine whether C. coyleae could be the etiological agent of UTI and to analyze its antibiotic susceptibility. Urine samples were cultured quantitatively according to accepted laboratory procedures. The identification of bacterial isolates was carried out using the Vitek MS (bioMérieux) and antibiotic susceptibility was tested using disc diffusion according to EUCAST guidelines. Between 1 January 2017 and 30 October 2018, a total of 39 C. coyleae strains were isolated. This represented 0.32% of all urine samples cultured in the laboratory during the collection period. The strains were isolated from samples obtained from 35 women and 3 men (age median for all-64 years). One female patient presented with C. coyleae in her urine twice at an interval of 21 months. In six cases of UTI, C. coyleae was isolated in monoculture. The isolates had the same resistance pattern. A total of 11 strains were obtained from cases with a clinical diagnosis of UTI. In 13 cases, the strain was cultured in a monoculture and in 28 cases with accompanying species. All strains were susceptible to vancomycin. However, resistance to ciprofloxacin was observed for 58.4% of the strains. Urine isolates of C. coyleae must be considered as contamination or normal flora in most cases (28/39, 72%). In the remaining cases, it can be considered as potential etiologic agents, mostly in women and especially in the 6 UTI cases where C. coyleae was found as the single culture-positive species. Several of these isolates demonstrate resistance to antibiotics commonly used in empiric treatment of urinary tract infections.
BACKGROUND:The study aim was to assess the prevalence of depression, anxiety, stress, and insomnia among resident doctors in Poland during the COVID-19 pandemic. MATERIAL AND METHODS:The online anonymous survey was conducted among Polish resident doctors attending obligatory specialization courses organized by the Center of Postgraduate Medical Education between 2020 and 2021. The psychological impact of COVID-19 was measured using the Depression, Anxiety, and Stress Scale (DASS-21). The sleep problems were assessed using the Insomnia Severity Index (ISI). RESULTS:Among 767 resident doctors participating in the study there were substantial levels of depression (14.7% mild, 26.2% moderate, 10.8% severe, and 9.5% extremely severe), anxiety (9.0% mild, 20.6% moderate, 8.3% severe, and 11.5% extremely severe), and stress (16.4% mild, 20.9% moderate, 15.7% severe, and 5.7% extremely severe), as well as substantial incidence of insomnia (58.0%), (38.3% subthreshold, 17.9% clinically moderate, and 1.7% clinically severe). Female doctors, physicians working directly with COVID-19 patients, and those who had COVID-19 themselves were at higher risk of depression, stress, and anxiety. Sleep disorders were more prevalent among doctors in surgical specializations, as well as those working directly with COVID-19 patients. CONCLUSIONS:The COVID-19 pandemic in Poland appears to have negatively affected doctors' mental health. High levels of depression, anxiety, stress, and insomnia indicate that systemic solutions are needed. A spectrum of interventions should be explored to mitigate further strain on the physicians' psychological health in the post-pandemic work environment. It is necessary to focus on groups at particular risk, such as women, front-line doctors, doctors in health crisis, and residents in selected fields of medicine.
To compare the effect of RYGB and OAGB on patients after failed treatment of obesity by laparoscopic sleeve gastrectomy (LSG). A case–control study based on a prospectively maintained database of reoperated patients after failed LSG, which included 33 patients who underwent RYGB conversion and 47 patients who underwent OAGB conversion. The mean %EBWL after a 5-year follow-up for RYGBc vs OAGBc was 84.04% vs 72.95% (p = 0.2176), respectively. Complete long-term diabetes remission was observed significantly more frequently in the OAGBc than in the RYGBc group (97.3% vs 33%; p = 0.035). There were no other statistically significant differences in the remission rate of comorbidities between RYGBc and OAGBc: hypertension 30% vs 27.3% (p = 0.261), dyslipidemia 83.3% vs 59.1% (p = 0.277), OSAS 100% vs 60% (p = 0.639), and GERD 40% vs 71.4% (p > 0.99), respectively. 7 patients were newly diagnosed with GERD after OAGBc and none after RYGBc. There were no statistically significant differences in the number of complications between the OAGBc and RYGB groups. The Comprehensive Complication Index was 17.85 (± IQR 29.6) in the OAGBc group and 14.92 (± IQR 21.75) in the RYGBc group (p = 0.375). The authors recognized complete long-term type 2 diabetes remission after conversion surgery as the most relevant difference, where the OAGB variety was found superior for its better efficacy. Any other statistically significant differences in the consequences after both conversion procedures used after the failure of LSG have not been stated. Both methods therefore can be considered to complete the initial treatment, considering the preferences and individual burdens of the patients.
Colorectal cancer (CRC) is often diagnosed at an advanced stage due to the invasiveness of colonoscopy; thus, non-invasive CRC diagnostics are desirable. CRC is associated with lipid alterations. We aimed to verify whether fatty acid (FA) profiles in CRC patients may serve as a potential diagnostic tool for CRC diagnosis. FA profiles were assayed by GC-MS in cancer tissue, paired normal mucosa and serum from CRC patients and healthy controls. The levels of very long FAs – VLCFAs (26:0, 28:0 and 26:1) were the most highly increased FAs in cancer tissue compared to normal colon mucosa. Moreover, these FA were present in serum of CRC patients, they were absent in the serum of healthy subjects, or present in only trace amounts. To verify if cancer cells are the source of small amounts of these VLCFAs in the serum of patients we performed experiment in HT-29 CRC cells, which proved that CRC cells can produce and release VLCFAs into the blood. Most importantly, we defined a panel of FAs that may be assayed in a single analysis that definitely distinguishes CRC patients and healthy subjects, which was confirmed by PLS-DA and multivariate ROC analysis (AUC = 0.985). This study shows that selected FA panel may serve as a diagnostic marker for CRC.
This is the first report on the epidemiology of biopsy-proven kidney diseases in Poland.The Polish Registry of Renal Biopsies has collected information on all (n = 9394) native renal biopsies performed in Poland from 2009 to 2014. Patients' clinical data collected at the time of biopsy, and histopathological diagnoses were used for epidemiological and clinicopathologic analysis.There was a gradual increase in the number of native renal biopsies performed per million people (PMP) per year in Poland in 2009-14, starting from 36 PMP in 2009 to 44 PMP in 2014. A considerable variability between provinces in the mean number of biopsies performed in the period covered was found, ranging from 5 to 77 PMP/year. The most common renal biopsy diagnoses in adults were immunoglobulin A nephropathy (IgAN) (20%), focal segmental glomerulosclerosis (FSGS) (15%) and membranous glomerulonephritis (MGN) (11%), whereas in children, minimal change disease (22%), IgAN (20%) and FSGS (10%) were dominant. Due to insufficient data on the paediatric population, the clinicopathologic analysis was limited to patients ≥18 years of age. At the time of renal biopsy, the majority of adult patients presented nephrotic-range proteinuria (45.2%), followed by urinary abnormalities (38.3%), nephritic syndrome (13.8%) and isolated haematuria (1.7%). Among nephrotic patients, primary glomerulopathies dominated (67.6% in those 18-64 years of age and 62.4% in elderly patients) with leading diagnoses being MGN (17.1%), FSGS (16.2%) and IgAN (13.0%) in the younger cohort and MGN (23.5%), amyloidosis (18.8%) and FSGS (16.8%) in the elderly cohort. Among nephritic patients 18-64 years of age, the majority (55.9%) suffered from primary glomerulopathies, with a predominance of IgAN (31.3%), FSGS (12.7%) and crescentic GN (CGN) (11.1%). Among elderly nephritic patients, primary and secondary glomerulopathies were equally common (41.9% each) and pauci-immune GN (24.7%), CGN (20.4%) and IgAN (14.0%) were predominant. In both adult cohorts, urinary abnormalities were mostly related to primary glomerulopathies (66.8% in younger and 50% in elderly patients) and the leading diagnoses were IgAN (31.4%), FSGS (15.9%), lupus nephritis (10.7%) and FSGS (19.2%), MGN (15.1%) and pauci-immune GN (12.3%), respectively. There were significant differences in clinical characteristics and renal biopsy findings between male and female adult patients.The registry data focused new light on the epidemiology of kidney diseases in Poland. These data should be used in future follow-up and prospective studies.
