RESUMO

BACKGROUND: Despite the advanced laboratory technologies available today, blood culture is the gold standard method in the diagnosis of bloodstream infections. Automated blood culture devices give blood culture results for laboratories approximately in 2 - 3 days up to 7 days. Moreover, some microorganisms like nonreproducible bacteria, fungi or viruses cannot be produced in culture. Among all samples taken for blood culture on suspicion of infection approximately 10% are determined as positive whereas the false positive rate due to contamination is 5%. Especially in life-threatening severe conditions such as sepsis early diagnosis and prompt treatment are crucial. Based on this the aim of this study is to investigate complete blood count parameters as potential early markers in Escherichia coli, Staphylococcus aureus and Candida albicans bloodstream infections using an ex vivo whole blood model. METHODS: Blood samples collected from healthy donors (n = 10) were treated with suspensions containing a certain concentration of microorganisms (107 CFU/mL for both E. coli ATCC 25922 and S. aureus ATCC 29213, 106 CFU/mL for C. albicans ATCC 14053). After bacteremia and candidemia were induced, complete blood count parameters were analyzed hourly in the samples until the end of the 4th hour with a Mindray BC-6800 hematology analyzer. Statistical analysis was performed by Tukey-Kramer post-hoc multiple comparison test and statistical significance was accepted as p < 0.05. RESULTS: When platelet derived parameter baseline values were compared to hourly values in E. coli and S. aureus induced whole blood samples, it was found that the decrease in PLT, P-LCC and the increase in IPF% was significant from the first hour whereas the increase in IMG% was found to be significant only from the 3rd hour onward. In the experiments with C. albicans, it was observed that the increase in IPF% and IMG% was significant from the 2nd and 3rd hour onward, respectively. There was no relationship between MPV, P-LCR, and NLR baseline and hourly results in any microorganism induced model. CONCLUSIONS: IPF% can guide clinicians in the early diagnosis and management of treatment of infections caused by S. aureus, E. coli, and C. albicans.

RESUMO

Objective: The purpose of this case report was to evaluate the effect of telehealth and postpartum care provided to a mother with maternal depression according to Watson's Theory of Human Caring during the pandemic on the improvement in the mother's emotional state and to evaluate the applicability of the model. Methods: Edinburgh Postnatal Depression Scale was administered to eight women who responded to the announcement made on social media, and verbal and written permission was obtained from the mother with the highest scale score. A total of six video calls were made with the mother via WhatsApp, twice a week in the first week after postnatal discharge and once a week in the next 4 weeks, in accordance with the form drawn up according to Watson's Theory of Human Caring. Results: In this study, it was observed that home-based telehealth and postpartum care provided using Watson's Theory of Human Caring, which includes a holistic approach, was very useful, and the care provided according to the model provided a positive improvement in the emotional state of the mother with depression. Conclusions: It was concluded that telehealth and postpartum care is useful in home-based care in extraordinary situations/quarantine conditions such as pandemic; care can also be provided in the form of telehealth service according to Watson's Theory of Human Caring to mothers with depression; and care provides positive improvement in the emotional state of mothers.

RESUMO

Differentiating PFAPA (periodic fever, aphthosis, pharyngitis, and adenitis) syndrome from familial Mediterranean fever (FMF) could be challenging in some cases. Galectin-3 is a lectin with regulatory functions in apoptosis and inflammation. We aimed to test whether galectin-3 could be a biomarker for differentiating PFAPA syndrome from FMF. Patients with PFAPA syndrome, FMF, cryopyrin-associated periodic syndrome (CAPS), and streptococcal pharyngitis, and healthy controls were included in this study. Serum galectin-3 levels were measured using enzyme-linked immunosorbent assay. Eighty-seven patients (36 with PFAPA, 39 with FMF, 8 with CAPS, 4 with streptococcal pharyngitis), and 17 healthy controls were included. Blood samples were drawn during attacks from 20 PFAPA and 7 FMF patients and attack-free periods from 22 PFAPA, 35 FMF, and 8 CAPS patients. The median serum galectin-3 level in the PFAPA-attack group (1.025 ng/ml) was significantly lower than the levels in healthy control (2.367 ng/ml), streptococcal pharyngitis (3.021 ng/ml), FMF attack (2.402 ng/ml), and FMF-attack-free groups (2.797 ng/ml) (p = 0.006, 0.03, 0.01, and < 0.001, respectively). PFAPA-attack-free group had lower galectin-3 levels than the FMF-attack-free group (1.794 vs. 2.797 ng/ml, respectively; p = 0.01). Galectin-3 levels did not differ significantly between CAPS and attack-free PFAPA patients (1.439 ng/ml vs. 1.794 ng/ml, respectively; p = 0.63). In our study, for the first time, we defined galectin-3 as a promising biomarker that differs between PFAPA and FMF patients during both disease flares and attack-free periods. Further studies with high number of patients could validate its role as a biomarker.

RESUMO

Testicular ischaemia reperfusion (I/R) injury results with serious dysfunctions in testis. This study aims to explore effects of soluble guanylate cyclase (sGC) stimulator Riociguat on experimental testicular I/R injury in rats. Twenty-one male rats were divided into three groups (Control, IR and IRR). The control group was not exposed to any application. Bilateral testis from IR and IRR animals were rotated 720° in opposite directions for 3 h to induce experimental testicular ischaemia. Animals in IR and IRR groups were subjected to 3 h of reperfusion. Isotonic and Riociguat were administered to the animals 30 min prior reperfusion by oral gavage. At the end of experiment, animals were sacrificed and tissue samples were used for analyses. Riociguat treatment significantly decreased tissue malondialdehyde and Luminol levels compared to the IR group (p < 0.05). The pathological changes, pro-apoptotic proteins (Bax, Caspase 3, and Caspase 9) and apoptotic index in the IR group were down regulated in Riociguat treated animals (p < 0.05). Riociguat treatment was also significantly increased anti-apoptotic Bcl-2 expression, but alleviated tissue injury via modulating pro-inflammatory cytokine IL-1ß levels and significantly (p < 0.05) down-regulating NF-κB activity. Moreover, mTOR and ERK phosphorylation increased in IR group (p < 0.05), but Riociguat treatment reduced protein phosphorylation. Our experiment indicated that targeting sGC might support surgical interventions in testicular I/R injury by modulating oxidative stress, inflammation, and apoptotic protein expression levels, but more detailed studies are required to explore the protective activity of Riociguat and underlying mechanisms in testicular I/R injury.

RESUMO

BACKGROUND: Studies mostly focused on risk factors and clinical status in children with cerebral palsy (CP). Various antiinflammatory markers may help us in the early diagnosis and clinical classification of cerebral palsy patients. In this study, the relationship between antiinflammatory marker levels and clinical status in patients with CP is determined. It is the first time that Fetuin-A and Paraoxonase-1 (PON-1) are examined in children with CP. METHODS: The study is conducted on 79 children which are divided into two groups as CP and control. Gross motor function and spasticity are evaluated in addition to biochemical parameters. RESULTS: There is a statistically significant difference between CP and control group in terms of PON-1 activity, high sensitive C-Reactive Protein, HDL, and total cholesterol levels. There is no statistically significant difference in Fetuin A levels between the two groups. DISCUSSION: In suspected CP patients less than 24 months of age who possess prenatal and postnatal risk factors, the determination of PON-1 activity can be considered as a biomarker to support early diagnosis.

RESUMO

INTRODUCTION: Inflammation, immune system disorders, Demodex infestation, neurovascular dysregulation and oxidative stress are thought to be contributory factors in the pathogenesis of rosacea. AIM: To evaluate the presence of Demodex mites, the morphologic features of the nailfold capillaries, and the systemic oxidative stress status in patients with rosacea. MATERIAL AND METHODS: Thirty-one patients diagnosed with rosacea and 37 healthy age- and gender-matched subjects were included in this prospective case-control study. The presence of Demodex infestation, the findings of nailfold capillaroscopy (NFC), and the status of systemic oxidative stress measured by total oxidant capacity (TOC), total antioxidant capacity (TAC) and oxidative stress index (OSI) were evaluated. RESULTS: Demodex infestation rates were significantly higher in rosacea patients than in controls (p = 0.001). Increases in the diameters of the capillaries and the presence of avascular areas and crossing and abnormal structures were significantly more common in rosacea patients than in the healthy controls (p < 0.01, p = 0.016, p = 0.02, p < 0.001, respectively), and hairpin structures were significantly less common in rosacea patients than in the controls (p < 0.001). The presence of crossing capillaries was positively correlated with higher TOC levels (p = 0.05), while abnormal structures were found to be correlated with lower levels of TAC (p = 0.045). CONCLUSIONS: Oxidative status and NFC may play diagnostic and prognostic roles in rosacea, which should be confirmed by studies with larger sample sizes.

RESUMO

Recently, insulin-like growth factor-1 (IGF-1), forkhead box transcription factor (Fox) O1, and mechanistic target of rapamycin complex 1 (mTORC1) signaling have been introduced as key elements in acne pathogenesis. The aim of this study is to investigate the relationship between serum levels of IGF-1, insulin-like growth factor binding protein-3 (IGFBP-3), FoxO1 and mTORC1, and the components of metabolic syndrome (MS) and AV. This prospective case-control study was carried out on 89 participants, including 49 AV patients and 40 controls. The serum levels of IGF-1, IGFBP-3, insulin, FoxO1, and mTORC1 were measured along with the components of MS. The blood pressure (BP) measures were significantly higher in the AV patients than in the controls (P = .001). The mean high-density lipoprotein cholesterol (HDL-C) levels were significantly lower in the AV patients than in the controls (P = .040). The numbers of accompanying MS components were significantly higher in the AV patients than in the controls (P = .001). The IGFBP-3 levels were significantly higher in the AV patients than in the controls (P = .02). The IGF-1, mTORC1, and FoxO1 levels were higher in the AV patients than in the controls; neither were statistically significant (P = .093, P = .741, and P = .564, respectively). The higher BP and IGFBP-3 levels, the lower HDL-C levels and the common presence of MS components demand caution in terms of new therapeutic strategies and possible associated comorbidities.

RESUMO

Balancing the processes of hematopoietic stem cell (HSC) differentiation and self-renewal is critical for maintaining a lifelong supply of blood cells. The bone marrow (BM) produces a stable output of newly generated cells, but immunologic stress conditions inducing leukopenia increase the demand for peripheral blood cell supply. Here we demonstrate that the proinflammatory cytokine interferon-γ (IFN-γ) impairs maintenance of HSCs by directly reducing their proliferative capacity and that IFN-γ impairs restoration of HSC numbers upon viral infection. We show that IFN-γ reduces thrombopoietin (TPO)-mediated phosphorylation of signal transducer and activator of transcription (STAT) 5, an important positive regulator of HSC self-renewal. IFN-γ also induced expression of suppressor of cytokine signaling (SOCS) 1 in HSCs, and we demonstrate that SOCS1 expression is sufficient to inhibit TPO-induced STAT5 phosphorylation. Furthermore, IFN-γ deregulates expression of STAT5-mediated cell-cycle genes cyclin D1 and p57. These findings suggest that IFN-γ is a negative modulator of HSC self-renewal by modifying cytokine responses and expression of genes involved in HSC proliferation. We postulate that the occurrence of BM failure in chronic inflammatory conditions, such as aplastic anemia, HIV, and graft-versus-host disease, is related to a sustained impairment of HSC self-renewal caused by chronic IFN-γ signaling in these disorders.

RESUMO

TAPL (ABCB9) is a homodimeric polypeptide translocation machinery which transports cytosolic peptides into the lumen of lysosomes for degradation. Since the function of proteins is strongly dependent on the interaction network involved, we investigated the interactome of TAPL. A proteomic approach allowed identification of the lysosome-associated membrane proteins LAMP-1 and LAMP-2B as the most abundant interaction partners. Albeit with low frequency, major histocompatibility complex II subunits were also detected. The interaction interface with LAMP was mapped to the four-transmembrane helices constituting the N-terminal domain of TAPL (TMD0). The LAMP proteins bind independently to TAPL. This interaction has influence on neither subcellular localization nor peptide transport activity. However, in LAMP-deficient cells, the half-life of TAPL is decreased by a factor of five, whereas another lysosomal membrane protein, LIMP-2, is not affected. Reduced stability of TAPL is caused by increased lysosomal degradation, indicating that LAMP proteins retain TAPL on the limiting membrane of endosomes and prevent its sorting to intraluminal vesicles.

RESUMO

Metal-organic framework (MOF) films can be used in various applications. In this work, we propose a method that can be used to synthesize MOF films localized on a single side of an anion exchange membrane, preventing the transport of the metal precursor via Donnan exclusion. This is advantageous compared to the related contra-diffusion method that results in the growth of a MOF film on both sides of the support, differing in quality on both sides. Our proposed method has the advantage that the synthesis conditions can potentially be tuned to create the optimal conditions for crystal growth on a single side. The localized growth of the MOF is governed by Donnan exclusion of the anion exchange membrane, preventing metal ions from passing to the other compartment, and this leads to a local control of the precursor stoichiometry. In this work, we show that our method can localize the growth of both Cu-BTC and ZIF-8 in water and in methanol, respectively, highlighting that this method can used for preparing a variety of MOF films with varying characteristics using soluble precursors at room temperature.

RESUMO

For the quantification of insulin activity, United States Pharmacopeia (USP) general chapter <121> continues to require the rabbit blood sugar test. For new insulin or insulin analogue compounds, those quantitative data are expected for stability or comparability studies. At Sanofi, many rabbits were used to fulfil the authority's requirements to obtain quantitative insulin bioactivity data until the in vivo test was replaced. In order to demonstrate comparability between the in vivo and in vitro test systems, this study was designed to demonstrate equivalency. The measurement of insulin lispro and insulin glargine drug substance and drug product batches, including stress samples (diluted or after temperature stress of 30 min at 80 °C), revealed a clear correlation between the in vitro and in vivo test results. The recovery of quantitative in vitro in-cell Western (ICW) results compared to the in vivo test results was within the predefined acceptance limits of 80% to 125%. Thus, the in vitro ICW cell-based bioassay leads to results that are equivalent to the rabbit blood sugar test per USP <121>, and it is highly suitable for insulin activity quantification. For future development compounds, the in vitro in-cell Western cell-based assay can replace the rabbit blood sugar test required by USP <121>.

RESUMO

BACKGROUND: The importance of COVID-19 vaccination for patients on immunosuppressive (IS) medication has increased due to the high risk of severe disease or mortality. Different vaccines have varying efficacy rates against symptomatic COVID-19, ranging from 46.8% to 95%. The objective of this study was to examine the differences in anti-Spike IgG, anti-Spike IgA, and neutralizing antibody (NAb) activity between the inactive CoronaVac vaccine and the mRNA-based BNT162b2 vaccine in IS patients. METHOD: A total of 441 volunteers, including 104 IS patients, 263 healthy controls (HC), who received two doses of CoronaVac or BNT162b2, and 74 unvaccinated patients with a history of SARS-CoV-2 infection, were included in the study. Anti-spike IgG, IgA, and NAb activity were investigated. RESULTS: Immunogenicity with BNT162b2 was higher than with CoronaVac, but in IS groups, it was lower than HC (CoronaVac-IS: 79.3%, CoronaVac-HC: 96.5%, p < 0.001; BNT162b2-IS: 91.3%, BNT162b2-HC: 100%, p = 0.005). With CoronaVac, anti-Spike IgG levels were significantly lower than BNT162b2 (CoronaVac-IS: 234.5AU/mL, CoronaVac-HC: 457.85AU/mL; BNT162b2-IS: 5311.2AU/mL, BNT162b2-HC: 8842.8AU/mL). NAb activity in the BNT162b2 group was significantly higher. NAb and anti-Spike IgG levels were found to be correlated. Among the IS group, a significantly lower response to the vaccines was observed when using rituximab. IgA levels were found to be lower with CoronaVac. CONCLUSIONS: Although immunogenicity was lower in IS patients, an acceptable response was obtained with both vaccines, and significantly higher anti-Spike IgG, anti-Spike IgA, and NAb activity levels were obtained with BNT162b2.

RESUMO

The homodimeric ATP-binding cassette (ABC) transport complex TAPL (transporter associated with antigen processing-like, ABCB9) translocates a broad spectrum of peptides from the cytosol into the lumen of lysosomes. The presence of an extra N-terminal transmembrane domain (TMD0) lacking any sequence homology to known proteins distinguishes TAPL from most other ABC transporters of its subfamily. By dissecting TAPL, we could assign distinct functions to the core complex and TMD0. The core-TAPL complex, composed of six predicted transmembrane helices and a nucleotide-binding domain, is sufficient for peptide transport, showing that the core transport complex is correctly targeted to and assembled in the membrane. Strikingly, in contrast to the full-length transporter, the core translocation complex is targeted preferentially to the plasma membrane. However, TMD0 alone, comprising a putative four transmembrane helix bundle, traffics to lysosomes. Upon coexpression, TMD0 forms a stable non-covalently linked complex with the core translocation machinery and guides core-TAPL into lysosomal compartments. Therefore, TMD0 represents a unique domain, which folds independently and encodes the information for lysosomal targeting. These outcomes are discussed in respect of trafficking, folding and function of TAPL.

RESUMO

Background and Aim: This study examined the effects of black cumin seed oil treatment on oxidative stress and the expression of radixin and moesin in the liver of experimental diabetic rats. Materials and Methods: Eighteen rats were divided into 3 equal groups (control, diabetes, treatment). The control group was not exposed to any experimental treatment. Streptozotocin was administered to the rats in the diabetes and treatment groups. A 2.5 mL/kg dose of black cumin seed oil was administered daily for 56 days to the treatment group. At the conclusion of the experiment, the blood level of malondialdehyde (MDA) and glutathione (GSH) was measured. The expression level and the cellular distribution of radixin and moesin in the liver were analyzed. Results: The plasma MDA (3.05±0.45 nmol/mL) and GSH (78.49±20.45 µmol/L) levels in the diabetes group were significantly different (p<0.01) from the levels observed in the control group (MDA: 1.09±0.31 nmol/mL, GSH: 277.29±17.02 µmol/L) and the treatment group (MDA: 1.40±0.53 nmol/mL, GSH: 132.22±11.81 µmol/L). Immunohistochemistry and western blotting analyses indicated that while the level of radixin was not significantly between the groups (p>0.05) and moesin expression was significantly downregulated (p<0.05) in the experimental group, the treatment was ineffective. Conclusion: The administered dose was sufficient to prevent oxidative stress, but was not sufficient to alleviate the effects of diabetes on moesin expression in hepatic sinusoidal cells.

RESUMO

The aim of this study is to eveluate levels of advanced oxidation protein products (AOPP) which are thought to increase in the polyp tissue and superoxide dismutase (SOD), an antioxidant enzyme, with using specthrophotometry in polyp tissue and healthy mucosa. 30 nasal polyp patients without inflammatory disease except for nasal polyposis were included in the study. The control group consisted of 18 patients who did not have allergy, asthma, inflammatory and granulomatous disease and planned surgery due to septum deviation and concha hypertrophy. AOPP and SOD tissue levels were measured by spectrophotometry in polyp tissue specimens taken from patients with nasal polyps and concha samples taken from patients in the control group. The mean AOPP tissue level of patients in the nasal polyposis group was statistically significantly higher than the control group. (p < 0.05). The mean SOD activity level was significantly lower in the nasal polyposis group than the control group. (p < 0.05) As a result of this study, high AOPP levels in polyp tissue and low SOD levels in polyp tissue compared to healthy nasal mucosa, oxidative stress plays an important role in nasal polyp development.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The liver and kidney are among the most important organs in the body, where metabolic and elimination functions take place. During this process, liver and kidneys may suffer damage due to ingestion or formation of toxic metabolites leading to organ loss and even death. Artichoke (Cynara scolymus L.) leaf has long been recognized as a popular herbal remedy in traditional medicines with beneficial effects on liver. AIM OF THE STUDY: In phytotherapy leaves are the part used to support the liver functions and for treatment of damage induced by various toxins, while fleshy receptacle is cooked as meal to support liver homeostasis. However, effects of other plant parts on liver such as stems, bracts have not much attracted the attention of scientific community so far. In this study we investigated comparatively the hepatoprotective and nephroprotective effects of different plant parts of artichoke, i.e. receptacles, outer bracts, inner bracts, and stems with that of leaves upon paracetamol-induction in rats. MATERIALS AND METHODS: Aqueous ethanol (80%) extracts obtained from the different parts of artichoke were administered for five consecutive days after paracetamol induction to rats. At the end of experimental period blood samples from the experimental animals were taken for biochemical tests, while livers and kidneys were removed for further histopathological evaluation. RESULTS: The histopathological examinations of liver and kidney tissues revealed that the receptacle and stem extracts of the artichoke were the most effective parts by improving the experimentally induced pathology in both liver and kidney. Biochemical tests also supported the histopathological data; receptacle, stem and bract extracts reduced serum alanine transaminase (ALT) and aspartate transaminase (AST) levels, but not alkaline phosphatase (ALP), creatinine and blood urea nitrogen (BUN) levels. CONCLUSIONS: Histopathological and biochemical studies have shown that receptacle and stem extracts of artichoke were found to exert higher protective activity on liver and kidney damage induced by paracetamol comparing to its bract and leaf extracts, the latest is officially recognized as herbal remedy.

RESUMO

BACKGROUND/AIM: Presepsin is a useful biomarker for diagnosing sepsis. This study aimed to investigate the relationship between oxidative stress and presepsin levels in animal models. MATERIALS AND METHODS: Sprague-Dawley rats were used for cecal ligation and puncture (CLP) and to generate massive bowel resection (MBR) models. Trunk blood was collected for analysis of presepsin. Liver and intestinal tissue samples were taken to determine oxidative stress parameters. RESULTS: Presepsin levels in MBR and CLP sepsis models were higher than those in control groups. Reactive oxygen and nitrogen species (RONS) and malondialdehyde levels were increased in the liver and small intestine of rats in both models, whereas glutathione levels were decreased. CONCLUSION: Presepsin levels and RONS may be released by the same mechanism which is closely associated with the progression of sepsis and inflammation in both CLP and MBR models.

RESUMO

People with high emotional and social capacity, people who can take them under control, understand and manage emotions of others expertly are more advantageous both in their private and professional lives. Under this scope, in order to investigate the effect of the emotional intelligence of nurses and midwives, who consist an important manpower in the health system, to their job satisfaction, an investigation has been conducted in Fethiye State Hospital with 80 individuals. Of the workers investigated, 36.3% were in 21-30 age group, 62.5% were 2 years-college graduated, 98.8% were clinical nurses, 36.3% worked since 6-10 years. It was found that total emotional intelligence of the workers was low (X=22.54, SS=5.14), and average job satisfaction levels were middle level (X=15.62, SS=3.27). A positive association was found between the emotional intelligence and job satisfaction. As a conclusion, the relationships between the demographic variables and emotional intelligence and job satisfaction were evaluated in the study.

RESUMO

PURPOSE:: To evaluate the levels of oxidative stress markers such as superoxide dismutase and malondialdehyde in eyes with pseudo-exfoliative glaucoma treated with and without topical coenzyme Q10 (CQ10) and vitamin E (Coqun drop). METHODS:: This prospective, randomized clinical study was conducted on 64 eyes of 64 patients. All patients underwent phacoemulsification and intraocular lens implantation surgery. Aqueous humor samples were aspirated from the anterior chamber at the beginning of cataract surgery. The pseudo-exfoliative glaucoma + Coqun group received topical Coqun (100 mg CQ10, 500 mg Vitamin E TPGS) twice daily for 1 month preoperatively, while the pseudo-exfoliative glaucoma group consisted of pseudo-exfoliative glaucoma cases who had not taken Coqun. Pseudo-exfoliation syndrome cases formed the pseudo-exfoliation syndrome group. The main outcomes were the superoxide dismutase and malondialdehyde levels of aqueous humor in both groups. RESULTS:: The mean aqueous humor superoxide dismutase level was significantly higher in the pseudo-exfoliative glaucoma group than in pseudo-exfoliative glaucoma + Coqun and pseudo-exfoliation syndrome groups (p < 0.001, p = 0.004, respectively). Also, the mean aqueous humor superoxide dismutase level was significantly lower in the pseudo-exfoliation syndrome group than in pseudo-exfoliative glaucoma + Coqun group (p = 0.009). The mean malondialdehyde levels showed no significant difference between the groups (p > 0.05 for all). CONCLUSION:: Our study showed lower aqueous humor level of superoxide dismutase in pseudo-exfoliation syndrome patients compared to pseudo-exfoliative glaucoma patients. Significantly lower superoxide dismutase level was observed in pseudo-exfoliative glaucoma patients who received topical Coqun compared to pseudo-exfoliative glaucoma patients without Coqun treatment. No significant change was observed on the malondialdehyde level during 1-month follow-up period.
