ABSTRACT

PURPOSE: Body donors continue to have an important role in anatomy education in medical schools. Furthermore, the demand for organ transplantation is increasing as life expectancy increases. In Turkey, there are efforts to enable both donations to be made through a single system. These issues were addressed together, and it was aimed to evaluate the level of knowledge and attitudes of medical and law students regarding tissue-organ and body donation. METHODS: A questionnaire consisting of 29 questions was administered to 693 individuals to measure these aspects. Data were analyzed using a one-way analysis of variance with Bonferroni correction. Categorical data collected during the study were summarized in terms of frequency and percentage. RESULTS: When asked about their willingness to donate their bodies, 39.4% answered no, 29.5% responded yes, and 31.1% were undecided. Regarding organ donation, 61.8% of the participants expressed willingness, 22.8% were undecided, and 15.4% declined. Notably, there was a significant difference between those who had prior knowledge of organ tissue and body donation and those who did not (p < 0.001). CONCLUSION: The findings of our research indicate that knowledge about organ tissue and body donation, as well as the inclination to donate, increased as medical education progressed into clinical practice. Additionally, the level of knowledge among university students on this subject was found to be correlated with whether they had received prior training on the topic. It was observed that there is a need to provide more education for students to understand the importance of organ and body donation.

ABSTRACT

Hand Osteoarthritis (HOA) is a frequently occurring musculoskeletal disease that impacts health. Diagnostic criteria often incorporate osteophytes documented through imaging procedures. Radiographic imaging is considered the gold standard; however, more sensitive and safer methods like ultrasound imaging are becoming increasingly important. We conducted a population-based cross-sectional study to examine the prevalence, grade, and pattern of osteophytes using high-resolution ultrasound investigation. Factory workers were recruited on-site for the study. Each participant had 26 finger joints examined using ultrasonography to grade the occurrence of osteophytes on a semi-quantitative scale ranging from 0-3, where higher scores indicate larger osteophytes. A total of 427 participants (mean age 53.5 years, range 20-79 years) were included, resulting in 11,000 joints scored. At least one osteophyte was found in 4546 out of 11,000 (41.3%) joints or in 426 out of 427 (99.8%) participants, but only 5.0% (553) of the joints showed grade 2 or 3 osteophytes. The total osteophyte sum score increased by 0.18 per year as age increased (p < 0.001). The distal interphalangeal joints were the most commonly affected, with 61%, followed by the proximal interphalangeal joints with 48%, carpometacarpal joint 1 with 39%, and metacarpophalangeal joints with 16%. There was no observed impact of gender or workload. In conclusion, ultrasound imaging proves to be a practical screening tool for osteophytes and HOA. Grade 1 osteophytes are often detected in the working population through ultrasound assessments and their incidence increases with age. The occurrence of grade 2 or 3 osteophytes is less frequent and indicates the clinical presence of HOA. Subsequent evaluations are imperative to ascertain the predictive significance of early osteophytes.

ABSTRACT

Background: Biobanks are essential structures for scientific research. The RHINEVIT biobank is used to recruit biomaterials from rheumatology patients in outpatient care and to conduct clinical research studies (e.g., cohort studies) and basic research. RHINEVIT established Broad Consents (BC) to allow extensive and relevant usage of data and biospecimens without the need for specific project restrictions. For quality assurance, we compared the consent rate of individual items of the BC versions in patients with systemic lupus erythematosus (SLE) in the longitudinal study. Methods: BCs were used for biomaterial donation. Informed consent data from RHINEVIT were analyzed. Due to the content restructuring of the BC items due to changes from the templates of the working group of the Medical Ethics Commissions in the Federal Republic of Germany and GDPR requirements, content mapping of the items was performed for the analysis. Results: From September 2015 to March 2022, 291 SLE outpatients donated biomaterials. In 119 patients, the BC was renewed at least once in a subsequent biomaterial donation. Three biomaterial donations were obtained from 21 patients and four from six patients using the respective BC. However, one consent was later revoked. Consent to the BC topics showed consistently high rates of agreement (range 97.5%-100%), with only some patients disagreeing with individual topics. This remained stable over time (median 526 days [Q1 400, Q3 844]). None of the patients disagreed with a certain topic in two consecutive visits. Conclusion: Modifications to the BC did not result in any relevant changes in the approval rates for SLE patients. RHINEVIT's BC is successfully used for the quality-assured handling of excellently annotated biomaterial. The long-term use of these highly valuable biospecimens for unrestricted research, also in an international context, remains assured.

ABSTRACT

BACKGROUND: Cancer is a life-threatening condition with an economic burden on societies. Phytotherapy is rapidly taking place in cancer research to increase the success of treatment and quality of life. Thymoquinone (TQ) is the main active phenolic compound obtained from the essential oil of the Nigella sativa (black cumin) plant seed. For a long time, black cumin has been used traditionally for the remedy of different diseases because of its various biological effects. It has been shown that most of these effects of black cumin seeds are due to TQ. TQ became a popular research topic for phytotherapy studies for its potential therapeutic applications, and more research is going on to fully understand its mechanisms of action, safety, and efficacy in humans. KRAS is a gene that regulates cell division and growth. Monoallelic variants in KRAS result in uncontrollable cell division, leading to cancer development. Studies have shown that cancer cells with KRAS mutations are often resistant to certain types of chemotherapy and targeted therapies. OBJECTIVE: This study aimed to compare the effect of TQ on cancer cells with and without KRAS mutation to better understand the reason why TQ may have different anticancer effects in the different types of cancer cells. METHODS: TQ was investigated for its cytotoxic and apoptotic effects in laryngeal cancer cells (HEp-2) without KRAS mutation and compared to mutant KRAS-transfected larynx cancer cells and KRAS mutation-carrying lung cancer cells (A549). RESULTS: We showed that TQ has more cytotoxic and apoptotic effects on laryngeal cancer cells without KRAS mutation than in cells with mutation. CONCLUSION: KRAS mutations decrease the effect of TQ on cell viability and apoptosis, and further studies are needed to fully understand the relationship between KRAS mutations and thymoquinone effectiveness in cancer treatment.

ABSTRACT

Objective: To compare physician and patient assessments of global disease activity in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and to identify associated factors. Methods: Global disease activity scores (0-10 points) were retrospectively analyzed from physicians and patients with AAV at each outpatient visit from 2010 to 2020. We compared the scores and performed a linear regression with a random effects to identify associated factors. Results: Patients (n = 143, 1,291 pairs, 52% female) had a mean 64 (±15) years of age and a mean disease duration of 9 (±7) years. Patients and physicians global disease activity assessments showed a moderate correlation (Pearson R 0.31, CI [0.23-0.52], p < 0.001). Linear regression showed a strong association between the physician-documented disease activity scores and serum CRP levels (ß = 0.22, CI [0.18, 0.28]), disease duration (ß = -0.022, CI [-0.04,-0.01]) and patients' assessment of disease activity (ß = 0.08, CI [0.04, 0.12]). By contrast, patient assessments were strongly associated with the degree of pain (ß = 0.30, CI [0.25, 0.35]), functional limitations in daily living (HAQ, ß = 0.49, CI [0.21, 0.78]) and the global physical well-being (NRS, ß = 0.39, CI [0.32, 0.46]). Conclusion: Patients' and physicians' assessments of disease activity correlated. High CRP levels and disease duration were associated with physician-assessed disease activity scores, while subjective limitations were associated with higher patient-assessed disease activity scores. These findings highlight and support the need to develop and evaluate patient-reported outcomes to assess disease activity in patients diagnosed with AAV.

ABSTRACT

Background: The COVID-19 pandemic led to transformations in healthcare infrastructures and increased use of (innovative) telemedicine (TM) tools. Comparison of the use of video consultation (VC) in rheumatology in the pre-pandemic period and during the pandemic might allow for evaluating this new form of consultancy in healthcare due to changing conditions and possibilities. Materials and methods: Cross-sectional nationwide online survey among German rheumatologists and rheumatologists in training between March and May 2021 promoted by newsletters and Twitter posts. Results: Results refer to 205 participants. The majority was male (59%), older than 40 years (90%). Thirty-eight percent stated to have employed TM before ("digital users"), 27% were using VC as part of their TM expertise ("VC-users"), 10% stated to have experience with TM but not VC ("TM-users"). Those negating the use of any TM (62%) were designated as "digital non-users." TM-Knowledge was self-rated as 4 [median on a Likert Scale 1 (very high) to 6 (very low)] with a significant difference between digital users (VC-user 2.7 ± 1.2, TM-user 3.2 ± 1.1) and digital non-users (4.4 ± 1.3). The reported significant increase of VC use during the lockdown periods and between the lockdowns compared to the pre-pandemic phase was regarded as a proxy for VC acceptance in the pandemic. Reasons for VC non-use were administrative/technical efforts (21%), lack of technical equipment (15%), time constraints (12%), time required for individual VC sessions (12%), inadequate reimbursement (11%), lack of demand from patients (11%), data security concerns (9%), poor internet connection (8%), and lack of scientific evaluation/evidence (5%). Physicians considered the following clinical situations to be particularly suitable for VC: follow-up visits (VC-user 79%, TM-user 62%, digital non-user 47%), emergency consultations (VC-user 20%, TM-user 33%, digital non-user 20%), and patients presenting for the first time (VC-user 11%, TM-user 19%, digital non-user 8%). Conclusion: Even though the pandemic situation, with social distancing and several lockdowns, provides an ideal environment for the implementation of new remote care forms as VC, its use and acceptance remained comparatively low due to multiple reasons. This analysis may help identify hurdles in employing innovative digital care models for rheumatologic healthcare.

ABSTRACT

OBJECTIVE: To evaluate musculoskeletal ultrasound (MSUS) as a screening tool for rheumatoid arthritis (RA) and osteoarthritis (OA) patients in a rheumatology-screening program. PATIENTS AND METHODS: To raise awareness for rheumatic diseases, a mobile rheumatology office was deployed in different cities of Germany ("Rheuma-Truck"). Standardized questionnaire assessment, testing for rheumatoid factor and citrullinated peptide antibodies and medical student driven MSUS of the clinically dominant hand/foot including wrist, MCP-II, -III, -V, PIP-II, -III, MTP-II and -V were offered free of charge to the population. In case of suspicious results, a rheumatologist was consulted. RESULTS: In MSUS, 192 of 560 selected volunteers (aged 18-89, mean 52.7 years; 72.9% female) had suspicious findings including synovitis or erosions primarily affecting the MTP-II (11.8%), dorsal wrist (8.9%), and MCP-II (7%). 354 of the 560 volunteers further visited a rheumatologist of whom 76 were diagnosed with RA. According to the 'US7 Score', a sum scores ≥ 5 was significantly predictive for RA (odds ratio (OR) 5.06; confidence interval (CI) 0.83-35.32). 313 volunteers displayed signs of OA including osteophytes, while MCP-II (36.2%), MCP-III (14.8%), and the wrist (10.5%) were mostly affected. Diagnosis of RA was favoured over OA if the wrist (OR 4.2; CI 1.28-13.95), MTP-II (OR 1.62; CI 1.0-2.6), and MCP-V (OR 2.0; CI 1.0-3.8) were involved. CONCLUSION: Medical student driven MSUS by the 'US7 Score' can facilitate diagnosis of RA in rheumatology-screening programs due to the level of the score and the affected joints. A high rate of unknown OA signs was detected by MSUS. A mobile rheumatology office displays an opportunity to screen patients for RA and OA.

ABSTRACT

This study aimed to evaluate the effects of the glucocorticoid prednisolone, the mycophenolic acid prodrug, azathioprine, and the fungi fermentation end product, mycophenolate mofetile on the embryological development of rats. Nine day-old rat embryos were cultured in rat serum containing prednisolone at varying concentrations (5-30 µg/ml) for 48 h. The test groups were cultured separately in rat serum containing 0.3-10 µg/ml azathioprine and 1-10 µg/ml mycophenolate mofetile. Embryonic development parameter effects of both drugs in combination with prednisolone (20 µg/ml) were studied using morphological methods, with special attention given to the incidence of malformations. The genotoxic effects of agents evaluated with the TUNEL test revealed that prednisolone is not a cause of developmental toxicity. The maximum safe dose of prednisolone that could be used in combination with other immunosuppressive agents was determined to be 20 µg/ml. Azathioprine was found to be toxic and teratogenic for the rat embryos beginning at a dose of 1 µg/ml. Dose-dependent toxic and teratogenic effects of mycophenolate mofetile were detected at doses lower than normal clinical ones.

ABSTRACT

BACKGROUND: Multimorbidity raises the number of essential information needed for delivery of high-quality care in patients with chronic diseases like rheumatoid arthritis (RA). We evaluated an innovative ICT platform for integrated care which orchestrates data from various health care providers to optimize care management processes. METHODS: The Horizon2020-funded research project PICASO (picaso-project.eu) established an ICT platform that offers integration of care services across providers and supports patients' management along the continuum of care, leaving the data with the owner. Strict conformity with ethical and legal legislations was augmented with a usability-driven engineering process, user requirements gathering from relevant stakeholders, and expert walkthroughs guided developments. Developments based on the HL7/FHIR standard granting interoperability. Platform's applicability in clinical routine was an essential aim. Thus, we evaluated the platform according to an evaluation framework in an observational 6-month proof-of-concept study with RA patients affected by cardiovascular comorbidities using questionnaires, interviews, and platform data. RESULTS: Thirty RA patients (80% female) participated, mean age 59 years, disease duration 13 years, average number of comorbidities 2.9. Home monitoring data demonstrated high platform adherence. Evaluations yielded predominantly positive feedback: The innovative dashboard-like design offering time-efficient data visualization, comprehension, and personalization was well accepted, i.e., patients rated the platform "overall" as 2.3 (1.1) (mean (SD), Likert scales 1-6) and clinicians recommended further platform use for 93% of their patients. They managed 86% of patients' visits using the clinician dashboard. Dashboards were valued for a broader view of health status and patient-physician interactions. Platform use contributed to improved disease and comorbidity management (i.e., in 70% physicians reported usefulness to assess patients' diseases and in 33% potential influence on treatment decisions; risk manager was used in 59%) and empowered patients (i.e., 48% set themselves new health-related goals, 92% stated easier patient-physician communications). CONCLUSION: Comprehensive aggregation of clinical data from distributed sources in a modern, GDPR-compliant cloud platform can improve physicians' and patients' knowledge of the disease status and comorbidities as well as patients' management. It empowers patients to monitor and positively contribute to their disease management. Effects on patients' outcome, behavior, and changes in the health care systems should be explored by implementing ICT-based platforms enriched by upcoming Artificial Intelligence features where possible.

ABSTRACT

BACKGROUND: Mobile medical applications (Apps) offer innovative solutions for patients' self-monitoring and new patient management opportunities. Prior to routine clinical application feasibility and acceptance of disease surveillance using an App that includes electronic (e) patient-reported outcome measures (PROMs) warrant evaluation. Therefore, we performed a proof-of-concept study in which rheumatoid arthritis (RA) patients used an App (RheumaLive) to document their disease. METHODS: Accurate PROM reporting via an App in comparison to paper-based versions was investigated to exclude media bias. Sixty participants recruited from 268 consecutive RA outpatients completed paper-based and electronic PROMs (Hannover Functional Questionnaire/derived HAQ; modified RA disease activity index) using the App at baseline and follow-up visits. Between visits, patients used their App on their own smartphone according to their preferences. The equivalence of PROM data and user experiences from patients and physicians were evaluated. RESULTS: Patients' (78.3% female) mean (SD) age was 50.1 (13.1) years, disease duration 10.5 (9.1) years, and paper-based HAQ 0.78 (0.59). Mean confidence in Apps scored 3.5 (1.1, Likert scale 1 to 6). ePROMs' scores obtained by patients' data entry in the App were equivalent to paper-based ones and preferred by the patients. After 3 months, the App retention rate was 71.7%. Patients' overall satisfaction with the App was 2.2 (0.9, Likert scale 1 to 6). Patients and physicians valued the App, i.e., for patient-physician interaction: 87% reported that it was easier for them to document the course of the disease using the App than "only" answering questions about their current health during routine outpatient visits. Further App use was recommended in 77.3% of the patients, and according to physicians, in seven patients, the App use contributed to an increased adherence to therapy. CONCLUSION: Our study provides an essential basis for the broader implementation of medical Apps in routine care. We demonstrated the feasibility and acceptance of disease surveillance using a smartphone App in RA. App use was convincing as a reliable option to perform continuous, remote monitoring of disease activity and treatment efficacy. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02565225 .

ABSTRACT

OBJECTIVE: The interchromosomal effect (ICE) refers to the uncertainty during meiosis where the rearrangement of the chromosomes affects the segregation of the chromosomes that are not involved in the structural chromosomal abnormalities. The aim of this study is to investigate the existence of ICE in the sperm nuclei of the males who have structural chromosomal abnormalities. MATERIAL AND METHODS: Nine male individuals who are the carriers of the structural chromosomal abnormalities (patient group) and 14 male individuals who did not have any chromosomal abnormalities (control group) were diagnosed by the classical cytogenetic analysis. The aneuploidy of chromosomes 2, 3, 12, 13, 17, 18, 21, X, and Y in the sperm nuclei was investigated using the fluorescence in situ hybridization (FISH) method in these individuals. The patient group included 5 Robertsonian translocation (ROB) carriers, 3 reciprocal translocation (RCP) carriers, and 1 inversion carrier. RESULTS: A total of 51921 sperm nuclei were analyzed (19484 from the patient group and 32437 from the control group). While ICE was determined in 4 of 5 patients who were the carriers of ROB and an inversion carrier patient, it was not determined in the patient carrier of RCP. CONCLUSION: Our results suggest that there is ICE in the male carriers with a structural chromosomal abnormality, which appears to be translocation, breakpoint, chromosome, and patient dependent.

ABSTRACT

Various factors cause aggression, which can be related to imbalance of T3 and T4 hormones, which can act as neurotransmitters and are reported to be elevated during aggression. This indicates changes in the hypothalamic-pituitary-thyroid axis that cause long-term changes in aggressive behaviour, especially in criminals. Moreover, mental and behavioural disorders possibly occur in individuals with impairment in thyroid hormone balance. The main rationale for this study was to asses if high T3, high T4, and low TSH hormones may have an effect on aggression-related crime tendency. Furthermore, the study aimed to measure levels of thyroid hormones in prisoners and to examine relationships of the hormone levels with crime rates. Our study was conducted in Ankara Sincan Closed Prisons. The study group consisted of 208 male volunteers who were imprisoned and the control group included 82 male volunteers who were not imprisoned. Prisoners in the study group were divided into two groups: those who committed aggression-related crime (Group A, n = 96) and prisoners convicted of other crimes (Group B, n = 112). Pulse rates, T3, T4, and thyroid-stimulating hormone (TSH) levels, and theT3/T4 ratio were measured in these prisoners. Data were analysed using the Wilcoxon rank sum test and chi-square Fisher's exact test to test for any statistically significant differences. Results showed that toxic goitre rates, T3 and T4 values, and pulse rates were significantly higher in Group A than in the control group. Significant increase in T3 and T4 levels and the presence of toxic goitre were associated with aggression-related crime. These examinations should be performed on prisoners in general, especially those convicted of violent crimes. Additional rehabilitation and research programs should also be developed for such patients.

ABSTRACT

The aim of this study was to investigate the relationship between KRAS LCS6 mutation and endometrial cancer (EC). The study included 105 patients who had hysterectomy for benign reasons and 99 EC patients. The patients with Type 1 EC were classified according to histological properties, cancer stage, grade, tumour dimension, myometrial invasion (MMI), lymphovascular invasion (LVI), cytology, and number of positive lymph nodes. KRAS LCS6 mutation was examined in blood samples taken from all patients in both groups. No statistically significant difference was determined between the EC patients and the control group in demographic features. Weight and the Body Mass Index (BMI) values were higher in EC group (p < .001). While the incidence of this polymorphism is 5.8% throughout the world, the polymorphism rate was found to be 16.2% in the EC group and 12.4% in the control group, with no statistically significant difference determined (p > .05). Despite the higher rate of LCS6 polymorphism incidence in EC patients in this study conducted on a relatively large sample, there was not found to be a statistically significant difference in comparison with the control group. In addition, the presence of LCS6 polymorphism was not determined to have an effect on EC histopathological characteristics.Impact statementWhat is already known on this subject? Endometrial cancer (EC) is a genital system cancer which is one of the most widespread gynecological cancers seen in the USA and other developed countries, In EC, the most frequently seen gene mutations are PTEN tumour suppressor gene, KRAS, ß1 catenin, BCL-2, CTNNB and P53 mutations. KRAS LCS6(let-7 miRNA binding region polymorphism) polymorphism has a worldwide incidence of 5.8% (Chin et al. 2008).There are studies shown that KRAS LCS6 polymorphism has an effect on developing EC (Lee et al. 2014), ovarian cancer(Ratner et al. 2010)and endometriosis in women (Grechukhina et al. 2012).What do the results of this study add? In our study, LCS6 located on KRAS 3'-UTR was found at the rate of 16.2% in Type 1 EC patients. This increase is noticeable when it is considered that the incidence of this polymorphism is 5.8% in the general population. The results of the current study supports the preliminary findings of Lee et al.What are the implications of these findings for clinical practice and/or further research? These new genetic markers could help to develop gene-targeted therapies, identify genetic basis of the disease and the factors that could affect the EC prognosis.

ABSTRACT

Inversion occurs after two breaks in a chromosome have happened and the segment rotates 180° before reinserting. Inversion carriers have produced abnormal gametes if there is an odd number crossing- over between the inverted and the normal homologous chromosomes causing a duplication or deletion. Reproductive risks such as infertility, abortion, stillbirth and birth of malformed child would be expected in that case. A 54-year- old male patient was consulted to our clinic for primary infertility. The routine chromosome study were applied using peripheral blood lymphocyte cultures and analyzed by giemsa-trypsin-giemsa (GTG) banding, and centromer banding (C-banding) stains. Y chromosome microdeletions in the azoospermia factor (AZF) regions were analyzed with polymerase chain reaction. Additional test such as fluorescence in situ hybridization (FISH) was used to detect the sex-determining region of the Y chromosome (SRY). Semen analysis showed azoospermia. A large pericentric inversion of chromosome 1 46,XY, inv(1) (p22q32) was found in routine chromosome analysis. No microdeletions were seen in AZF regions. In our patient the presence of SRY region was observed by using FISH technique with SRY-specific probe. Men who have pericentric inversion of chromosome 1, appear to be at risk for infertility brought about by spermatogenic breakdown. The etiopathogenic relationship between azoospermia and pericentric inversion of chromosome 1 is discussed.

ABSTRACT

The importance of elevated intra-abdominal pressure (IAP) and abdominal compartment syndrome (ACS) have been recognized in critical care for its potential damaging effects. But, quantification of IAP values may be useful as a clinical tool for determining efficacy of coughing and straining for functional recovery of OA patients. We would like to evaluate IAP generated in an OA patient and the effect of negative pressure therapy (NPT) and dynamic abdominal closure systems (ABRA) on the IAP values at rest and during coughing and straining and compare those with IAP measurements of closed abdomen after standard open elective colorectal surgery (non-OA). Eight OA and eight non-OA patients were included in this study. OA patient with NPT and ABRA (OA + NA), OA patient without NPT and ABRA completely unbraced (OA-NA) (NA stands for NPT and ABRA), and non-OA patients underwent IAP measurements at rest, during coughing, and during straining via transurethral catheter. There was no difference in the mean of IAP measurement at rest in OA-NA (6.1 mmHg), OA + NA (6.5 mmHg), and non-OA (6.0 mmHg) patients. During coughing, IAP of OA-NA, OA + NA, and non-OA patients were 11.5, 19.1, and 22.0 mmHg and during straining, IAP of OA-NA, OA + NA, and non-OA patients were 11.5, 17.5, and 23.5 mmHg, respectively. Application of NPT in conjunction with ABRA did not increase IAP at rest but provided significant IAP increase in OA + NA patients, when compared to OA-NA patients during coughing and straining. NPT in conjunction with ABRA offers the advantage of increase of IAP during coughing and straining.

ABSTRACT

OBJECTIVE: To identify the genetic risk markers of aggressive periodontitis (AgP), researchers focus on genetic components that regulate the immune response. Therefore the purpose of this study was to investigate genetic impact of monocyte chemoattractant protein (MCP)-1-2518A/G and CC chemokine receptor 2 (CCR2) -190G/A gene polymorphisms on AgP susceptibility and the effect of this polymorphism on MCP-1 gene expression in patients with AgP. MATERIAL AND METHODS: A total of 215 subjects, 108 AgP and 107 periodontally healthy (H) were recruited in this cross-sectional study (NCT02817568). Gene polymorphisms of MCP-1-2518A/G and CCR2-190G/A were analyzed by a standard polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. MCP-1 messenger (m) RNA expression was measured using quantitative real-time (RT)-PCR in peripheral blood leukocytes from 26 AgP and 16H controls. Threshold cycles (Ct) values were obtained from the RT-PCR analysis based on SYBR Green detection and data was normalized via ΔCt. RESULTS: There were no differences between AgP and H groups with regard to MCP-1 and CCR2 genotype distribution and allele frequencies (p>0.05). In contrast, the MCP-1 mRNA expression levels were higher in homozygous "AA" control subjects than having G+ genotype and AA homozygous AgP patients. CONCLUSIONS: It can be concluded that MCP-1 and CCR2 polymorphisms are not associated with AgP in Turkish population. Although in AgP patients, there was AA genotype with MCP-1 mRNA expression it can be speculated that gene expression levels in peripheral blood may not reflect the cytokine/chemokine levels of local tissues.

ABSTRACT

Hemodynamic resuscitation, source control, and delayed abdominal closure are the three fundamental steps for open abdomen (OA) management. When to start delayed abdominal closure and how to determine which delayed closure method should be applied to each OA patient are not clarified in the literature. We evaluated an algorithm that was developed to address these two questions. A retrospective chart review was conducted for OA patients treated for according to the algorithm. When hemodynamic stabilization and source control using negative pressure therapy resulted in regression of sepsis and decreased procalcitonin levels, patients were assigned to either the skin-only or fascial closure groups according to their Björck scores and open abdominal fascial closure (OAFC) scores. The novel OAFC scoring system was created by adding age and malignancy to the sequential organ failure assessment (SOFA) score. For skin-only closure, skin flaps and skin grafts were used; for fascial closure, an abdominal re-approximation anchor system (ABRA) or ABRA plus biologic mesh was applied. From January 2008 through September 2014, 108 OA patients were managed based on the algorithm; 61 were included in this study. Abdominal closure rate was 90.2 % (55/61). Overall hospital mortality rate was 11.4 % (7/61). Small hernias developed in only 12.5 % (4/32) of the fascial closure group. In this retrospective study, the algorithm with the novel OAFC score provided practical and valid guidance to clarify when to start delayed abdominal closure and which delayed closure method to use for each OA patient.
