    Observation of Two Excited Bc+ States and Measurement of the Bc+ (2S) Mass in pp Collisions at ?s=13 TeV
    (Amer Physical Soc, 2019) Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Bergauer, T.; Brandstetter, J.; Dragicevic, M.
    Signals consistent with the B-c(+)(2S) and B-c*(+)(2S) states are observed in proton-proton collisions at root s = 13 TeV, in an event sample corresponding to an integrated luminosity of 143 fb(-1), collected by the CMS experiment during the 2015-2018 LHC running periods. These excited (b) over barc states are observed in the B-c(+)pi(+)pi(-) invariant mass spectrum, with the ground state B-c(+) reconstructed through its decay to J/psi pi(+). The two states are reconstructed as two well-resolved peaks, separated in mass by 29.1 +/- 1.5(stat) +/- 0.7(syst) MeV. The observation of two peaks, rather than one, is established with a significance exceeding five standard deviations. The mass of the B-c(+)(2S) meson is measured to be 6871.0 +/- 1.2(stat) +/- 0.8(syst) +/- 0.8(B-c(+)) MeV, where the last term corresponds to the uncertainty in the world-average B-c(+) mass.

    Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets
    (Amer Physical Soc, 2019) Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Bergauer, T.; Brandstetter, J.; Dragicevic, M.
    Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.

    Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions
    (Amer Physical Soc, 2023) Tumasyan, A.; Adam, W.; Bergauer, T.; Dragicevic, M.; Del Valle, A. Escalante; Fruhwirth, R.; Jeitler, M.
    The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization. This study uses a data sample of ultraperipheral lead-lead collisions at ffiffiffiffiffiffiffi p = 5.02 TeV, corresponding to sNN an integrated luminosity of 0.38 nb-1, collected with the CMS experiment at the LHC. The measured second harmonic of the correlation between the sum and difference of the two jet transverse momentum vectors is found to be positive, and rising, as the dijet transverse momentum increases. A well-tuned model that has been successful at describing a wide range of proton scattering data from the HERA experiments fails to describe the observed correlations, suggesting the presence of gluon polarization effects.

    Search for Supersymmetry in pp Collisions at ?s=13 TeV in the Single-Lepton Final State Using the Sum of Masses of Large-Radius Jets
    (Amer Physical Soc, 2017) Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.
    Results are reported from a search for supersymmetric particles in proton-proton collisions in the final state with a single lepton, multiple jets, including at least one b-tagged jet, and large missing transverse momentum. The search uses a sample of proton-proton collision data at root s = 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb(-1). The observed event yields in the signal regions are consistent with those expected from standard model backgrounds. The results are interpreted in the context of simplified models of supersymmetry involving gluino pair production, with gluino decay into either on- or off-mass-shell top squarks. Assuming that the top squarks decay into a top quark plus a stable, weakly interacting neutralino, scenarios with gluino masses up to about 1.9 TeV are excluded at 95% confidence level for neutralino masses up to about 1 TeV.

    Using Z Boson Events to Study Parton-Medium Interactions in Pb-Pb Collisions
    (Amer Physical Soc, 2022) Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Bergauer, T.; Dragicevic, M.; Ero, J.
    The spectra measurements of charged hadrons produced in the shower of a parton originating in the same hard scattering with a leptonically decaying Z boson arc reported in lead-lead nuclei (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. Both Pb-Pb and pp data sets are recorded by the CMS experiment at the LHC and correspond to an integrated luminosity of 1.7 nb(-1) and 320 pb(-1), respectively. Hadronic collision data with one reconstructed Z boson candidate with the transverse momentum p(T) > 30 GeV/c are analyzed. The Z boson constrains the initial energy and direction of the associated parton. In heavy ion events, azimuthal angular distributions of charged hadrons with respect to the direction of a Z boson are sensitive to modifications of the in-medium parton shower and medium response. compared to reference data from pp interactions, the results for central Pb-Pb collisions indicate a modification of the angular correlations. The measurements of the fragmentation functions and p(T) spectra of charged particles in Z boson events, which are sensitive to medium modifications of the parton shower longitudinal structure, are also reported. Significant modifications in central Pb-Pb events compared to the pp reference data are also found for these observables.

    Search for Low-Mass Quark-Antiquark Resonances Produced in Association with a Photon at ?s=13 TeV
    (Amer Physical Soc, 2019) Sirunyan, A. M.; Tumasyan, A.; Adam, W.; Ambrogi, F.; Asilar, E.; Bergauer, T.; Brandstetter, J.
    A search for narrow low-mass resonances decaying to quark-antiquark pairs is presented. The search is based on proton-proton collision events collected at 13 TeV by the CMS detector at the CERN LHC. The data sample corresponds to an integrated luminosity of 35.9 fb(-1), recorded in 2016. The search considers the case where the resonance has high transverse momentum due to initial-state radiation of a hard photon. To study this process, the decay products of the resonance are reconstructed as a single large-radius jet with two-pronged substructure. The signal would be identified as a localized excess in the jet invariant mass spectrum. No evidence for such a resonance is observed in the mass range 10 to 125 GeV. Upper limits at the 95% confidence level are set on the coupling strength of resonances decaying to quark pairs. The results obtained with this photon trigger strategy provide the first direct constraints on quark-antiquark resonance masses below 50 GeV obtained at a hadron collider.

    Effectiveness of Different Surgical Flap Delay Methods and Their Systemic Toxicities
    (Lippincott Williams & Wilkins, 2021) Yildiz, Kemalettin; Mirapoglu, Semih Lutfi; Kilic, Ulkan; Guneren, Ethem; Kocyigit, Abdurrahim; Kirazoglu, Ahmet; Sagir, Haci Omer
    Objective: The surgical flap delaying has been shown to be effective in preventing partial flap loss or in preparing larger flaps. However, there is no gold standard flap delay method in the literature. In this study, the authors aimed to compare 3 types of surgical delay methods to determine which model would increase more flap survival. The authors also investigated the effect of delay methods on circulating mononuclear leukocytes as a parameter of DNA damage. Methods: Twenty-four Sprague-Dawley male rats were divided into 4 groups. All subjects had a 10 x 3 cm modified McFarlane flap. Surface area measurements, biopsies, and blood samples were taken on the day of sacrification; 7th day for the control group and 14th day for delay groups. Results: Between incisional surgery delay groups, a significant difference was found in necrosis and apoptosis in the bipedicled group, and only necrosis in the tripedicled group compared to the control. In terms of DNA damage, it was found higher in all experimental groups than in the control group. Conclusions: Both incisional surgical delay procedures' results were meaningfully effective when only incisions were made without the elevation of flaps. In conclusion, bipedicled incisional surgical delay seems to be the most effective method in McFarlane experimental flap model whereas two-staged surgeries may increase the risk of systemic toxicity.

    Effects of Platelet Rich Plasma and Amniotic Cell Culture Medium on Wound Healing Following Experimental Animal Tracheal Injury Model: A Comparative Study
    (Lippincott Williams & Wilkins, 2021) Mirapoglu, Semih L.; Guler, Eray M.; Tok, Olgu E.; Aydogdu, Ibrahim; Cay, Ali; Camli, Mehmet F.; Kocyigit, Abdurrahim
    Introduction: Prolonged inflammation after tracheal injury invariably results in a degree of stenosis. The topical application of platelet-rich plasma (PRP) and human amniotic fluid-derived cell culture medium (ACCM) have been shown to promote wound healing. The effects of PRP and amniotic cell culture medium (Gibco AmnioMAX - II ) were investigated in a rat model through morphometric, histological, and biochemical parameters. Material & Methods: Thirty-two male Sprague Dawley rats were included in the study: 4 rats provided for the preparation of PRP. Three groups of 7 rats were divided into PRP and ACCM groups, a control and a sham group respectively. A transverse incision on the ventral aspect of the third trachea spanning half of the tracheal circumference was performed. The incision was repaired with 7/0 polypropylene in the sham group. In the control group, 0.5 ml saline solution was applied on to the repaired injury site. In the other two groups, 0.5 mL PRP or ACCM were applied topically on the tracheal repair. Tissue samples were harvested 30 days after surgery for morphometric measurements and biochemical analyses for oxidative stress markers, IL-1beta, IL-6, and VEGF. Connective tissue thickness was evaluated histologically. Statistical analysis included the Mann-Whitney U and Kruskal Wallis tests. Results: A notable difference was detected (P = 0,025) in cartilage segment length measurements of the trachea between the ACCM group and the sham and control groups (P < 0.03). A significant difference was found in the analysis of TAS, TOS, and OSI values between the study groups and the control and sham groups (P < 0.005). There were also differences in IL1-beta and IL-6 levels between ACCM and PRP groups (P < 0.05). For the same parameters, the differences were significant between the PRP and, sham and control groups (P = 0,004 and P = 0,002 respectively), and between the ACCM and, sham and control groups (P = 0,003 and P = 0,002 respectively). VEGF values demonstrated a significant difference between the PRP and sham group (P = 0,002), and between ACCM and sham/control groups (p=0,002 for both), the highest VEGF value was in ACCM group while the lowest value was in the sham group. In the histological assessment of connective tissue, a significant difference was observed between ACCM and the other groups. Conclusion: Amniotic fluid-derived cell culture medium shows less oxidative stress status than the other applications. ACCM is more effective on inflammatory and angiogenetic processes. Connective tissue thickness results were consistent with those biochemical and morphologic results. Additionally, a significant difference was observed in histological data between ACCM and PRP. Overall, ACCM proved to be efficient on tracheal healing. These effects can be attributed to the abundance of growth factors in both PRP and amniotic fluid-derived cell culture medium (ACCM).

    Evaluation of Airway Volume in Cleft Lip and Palate Following Nasoalveolar Molding
    (Lippincott Williams & Wilkins, 2018) Astani, Seyed Amirhossein; Yilmaz, Hanife Nuray; Nevzatoglu, Sirin; Demirkaya, Arzu Ari; Acar, Zeynep Ahu
    Patients with cleft lip and palate (CLP) have commonly reduced nasal airways and are more prone to snoring, mouth breathing and hypopnea during sleep. Therefore, the morphometric evaluation of pharyngeal airway in patients with CLP is crucial. The purpose of this study is to evaluate the pharyngeal airway volumes of patients with CLP who underwent nasoalveolar molding (NAM) and to compare them with a well-matched control group without NAM. The study consisted of 40 patients with CLP divided into 2 main groups (26 with NAM; 14 without NAM) and 4 subgroups (15 unilateral CLP [UCLP] with NAM, mean age: 10.13 +/- 1.30 years; 11 bilateral CLP [BCLP] with NAM, mean age: 10.55 +/- 1.51 years; 7 UCLP without NAM, mean age: 9.86 +/- 1.68 years; 7 BCLP without NAM, mean age: 10.28 +/- 1.89 years). Nasopharyngeal, oropharyngeal, and total airway volumes of all the patients were calculated 3-dimensionally with cone-beam computed tomography. There were statistically significant differences in nasopharyngeal volume (P< 0.05) of NAM group compared to control group; however, volumetric differences in oropharyngeal and total pharyngeal airway were not significant (P> 0.05). The amount of nasopharyngeal, oropharyngeal, and total pharyngeal airway size in the BCLP with NAM group was significantly larger compared to BCLP without NAM group (P< 0.05). However, UCLP did not show any significant difference in NAM group (P> 0.05). This study implies that NAM can effectively enlarge the nasopharyngeal airway size in patient with CLP. In addition, the pharyngeal airway volume enlargement is more apparent in BCLP than UCLP individuals.

    Dorsal Augmentation of Saddle Nose Deformity With Toothpick-Shaped Costal Cartilage Grafts in the Secondary Septorhinoplasty
    (Lippincott Williams & Wilkins, 2017) Cevizci, Rasit; Bezgin, Selin Ustun; Cakir, Burak Omur; Kersin, Burak; Bayazit, Yildirim Ahmet
    Saddle nose deformity is a challenging complication of septoplasty or septorhinoplasty, characterized by underprojected cartilaginous dorsum. Nasal dorsal augmentation is a significant part of reconstructive surgery of saddle nose deformities. In this study, the authors aimed to discuss the results of using toothpick-shaped costal cartilage grafts in nasal dorsal augmentation of saddle nose deformity. Twelve patients who underwent nasal dorsal augmentation due to moderate to severe saddle nose deformity secondary to the previous septoplasty or septorhinoplasty were retrospectively reviewed. Costal cartilage grafts prepared in the shape of toothpicks were used in all patients. Costal cartilage was used as toothpick-shaped free grafts in 12 patients (female: 7, male: 5) with a mean age of 42 (range: 24-56) for dorsal augmentation in the secondary septorhinoplasty. All patients had a history of previous surgery (septoplasty, n=9; and septorhinoplasty, n=3). All patients were operated under general anesthesia with open technique septorhinoplasty. The mean follow-up was 18 (range: 9-48) months. In only 1 of the 12 patients, a postoperative complication was observed including an infection of the tip area in the second postoperative week. None of the patients experienced donor site complications or major graft resorption. All patients were satisfied with functional and esthetic outcomes. No revision surgery was needed in any patient. Toothpick-shaped costal cartilage grafts are useful in nasal dorsal augmentation of moderate to severe saddle nose deformity. This technique offers smooth camouflage, satisfactory accordance with the recipient region, and shorter operation time. In addition, it avoids the side effects from wrapping techniques such as foreign body reaction or additional donor site morbidities.

    Comparison of new and classical point mutations associated with clarithromycin resistance in Helicobacter pylori strains isolated from dyspeptic patients and their effects on phenotypic clarithromycin resistance
    (Microbiology Soc, 2019) Kocazeybek, Bekir; Sakli, Merve Kutlu; Yuksel, Pelin; Demirci, Mehmet; Caliskan, Reyhan; Sarp, Tevhide Ziver; Saribas, Suat
    Purpose. We aimed to investigate the presence of three recently identified point mutations (A2115G, G2141A and A2144T) of the 23 S rRNA gene and compare them with the three most frequently encountered point mutations (A2142G, A2142C and A2143G) in Helicobacter pylori strains in Turkey. Methodology. A total of 63 patients (mean 47.08 +/- 12.27) were included. The E-test method (for clarithromycin) was used for the clarithromycin antimicrobial susceptibility test of isolated H. pylori strains. Real-time PCR was used to detect the point mutations. Results. A total of 24 out of 63 H. pylori strains (38.1%) were detected as clarithromycin resistant (>0.5 mg l(-1)). The new A2115G (n:6, 25%), A2144T (n: 7, 29.1%) and G2141A, 8 (n: 8, 33.3%) mutations and the classical A2142G (n: 8, 33.3%) and A2143G (n: 11, 45.8%) point mutations were detected in the 24 clarithromycin-resistant strains. The A2144T point mutation had the highest median MIC value (3 mg l(-1)) amongst the new mutations, but the classical mutations (A2142G and A2143G) had the highest median MIC values (256 mg l(-1)) overall. The presence of the A2115G (OR: 31.66), A2144T (OR: 36.92) or G2141A (OR: 28.16) mutations increased the likelihood of clarithromycin resistance in H. pylori strains by 31.66-, 36.92- and 28.16-fold (ORs), respectively, according to the binary logistic regression analysis. Conclusion. We concluded that classical mutations of the 23 S rRNA gene resulted in higher clarithromycin MIC values than new mutations. These new point mutations caused moderate elevations in the MIC values of clarithromycin-resistant H. pylori strains.

    Anatomical and Morphological Assessment of Nasopalatine Canal in Pediatric and Adolescent Population via Cone Beam Computed Tomography
    (Lippincott Williams & Wilkins, 2021) Aydin, Kader Cesur; Gas, Selin
    Introduction: Anatomical and morphological structure of nasopalatine canal (NPC) is important for surgical techniques carried out on the maxilla. The aim of the present study was to analyze the anatomical and morphological characteristics of the NPC among pediatric and adolescent population using cone beam computed tomography (CBCT). Materials and Methods: A total of 437 cases were analyzed using CBCT images in this retrospective, cross-sectional study. Shape was analyzed as hourglass, cone, funnel, banana, cylindrical, and tree branch like. Number of foramina Stenson (FS) was evaluated through coronal, axial, and sagittal views. Landmark evaluation involved; diameter of FS, diameter of incisive foramen, diameter at the mid-canal length, NPC length, and narrowest buccal bone thickness. Pathology presence near NPC was evaluated to determine alterations on the landmark metrics. Results: Nasopalatine canal shape distribution revealed 32% hourglass, 9.6% conic, 10.8% funnel, 11.9% banana, 29.5% cylindrical and 6.2% tree branch. Number of FS (P = 0.021; P < 0.05), diameter of FS (P = 0.041; p < 0.05), NPC length (P: 0.020; P < 0.05), and narrowest buccal bone thickness from the mid-canal length was significantly higher in males (P: 0.000; P < 0.05). Diameter of incisive foramen and diameter at the mid-canal length revealed no significance among genders (P (1) = 0.318, P (2) = 0.105; P > 0.05). Incidence of pathology near NPC is 20.8% and was not affected by gender (P = 0,192; P > 0.05). Conclusions: The current study demonstrates significant variations of NPC morphology among patients. Therefore, CBCT analysis is highly recommended for clinicians to reduce the complications in oral and maxillofacial surgery practices and to provide better surgical outcomes.

    Effects of Electrical Stimulation on Meat Quality of Lamb and Goat Meat
    (Hindawi Ltd, 2012) Cetin, Omer; Bingol, Enver Baris; Colak, Hilal; Hampikyan, Hamparsun
    Effect of various voltage of electrical stimulation (ES) on meat quality of lamb and goat was investigated by using a total of 36 animals at 3-5 years old. Constant 50 Hz frequency and 50, 100, and 250 V, 90 sec of ES were administered to 1/2 carcasses and were examined according their textural, physicochemical, and sensorial characteristics. ES decreased the pH values of lamb and goat meat, and accelerated the rigor mortis (P < 0.05). Additionally, ES enhanced the water activity, water-holding capacity, and drip loss of both animals. Shear force varied between lamb and goat meat, and tenderness was improved depending on voltage range used (P < 0.001). ES caused difference in instrumental colour (CIE L*, a*, b*) values of lamb and goat meat compared with the control groups (P < 0.05) during aging period at 4 degrees C. Sensorial characteristics were also improved with various levels of ES treatments. In conclusion, ES had positive effects on meat quality of lamb and goat, in contrast to undesirable consumer preferences.

    (Hindawi Ltd, 2012) Colak, Hilal; Hampikyan, Hamparsun; Bingol, Enver Baris; Cetin, Omer; Akhan, Meryem; Turgay, Sumeyre Ipek
    Tarhana is a popular traditional Turkish cereal-based fermented food product mainly produced at home or at home scale level. Some certain mould species can grow even at low moisture and pH values and produce aflatoxins in food. This study was conducted to determine aflatoksin levels in tarhana. For this purpose, a total of 138 tarhana powder samples were collected from bazaars in Istanbul and analyzed for aflatoxins, mould contamination, and some physco-chemical parameters. As a result, 32 out of 138 tarhana samples (23.2%) were found to be contaminated with aflatoxins in the range of 0.7-16.8 mu g/kg, whereas 29 samples contained Aflatoxin B1 (AFB1) ranging from 0.2-13.2 mu g/kg. All samples (100%) contaminated with moulds in the range of 1.4 x 10(1)-5.8 x 10(7)cfu/g. The average pH, moisture and a(w) results were detected as 3.82, 12.71%, and 0.695, respectively.

    The Effect of Reflexology on Low Back Pain in Operating Room Nurses
    (Lippincott Williams & Wilkins, 2022) Kandemir, Didem; Abdullayev, Aysegul; Ak, Ezgi Seyhan; Ugras, Gulay Altun; Kanan, Nevin
    Operating room nurses often face acute or chronic back and low back pains, shoulder and neck injuries. In recent years, the use of complementary and alternative treatment methods has been increasing due to the fact that pharmacological treatment cannot control the pain in general, and its various side effects and cost. The aim of this study was to investigate the effect of foot reflexology on low back pain of operating room nurses. This quasiexperimental study was conducted with 38 operating room nurses. The nurses in the experimental group were given a 30-minute reflexology protocol once a week for 4 weeks and their pain levels were assessed again at week 5. The control group nurses did not receive any intervention. Data were collected using a demographic information form and a visual analog scale (VAS). The low back pain of the nurses in the reflexology group decreased significantly at week 5 compared with week 1, whereas the severity of low back pain of the nurses in the control group did not change between weeks 1 and 5. There were no statistically significant differences between the groups in terms of the mean VAS pain score at week 1. However, the nurses in the reflexology group had significantly lower VAS pain mean scores at week 5 than the control group. In this study, reflexology significantly reduced the pain of nurses who had low back pain. Therefore, reflexology might be useful in controlling low back pain of operating room nurses.

    An Appeal to the Global Health Community for a Tripartite Innovation: An Essential Diagnostics List, Health in All Policies, and See-Through 21st Century Science and Ethics
    (Mary Ann Liebert, Inc, 2015) Dove, Edward S.; Barlas, I. Omer; Birch, Kean; Boehme, Catharina; Borda-Rodriguez, Alexander; Byne, William M.; Chaverneff, Florence
    Diagnostics spanning a wide range of new biotechnologies, including proteomics, metabolomics, and nanotechnology, are emerging as companion tests to innovative medicines. In this Opinion, we present the rationale for promulgating an Essential Diagnostics List. Additionally, we explain the ways in which adopting a vision for Health in All Policies could link essential diagnostics with robust and timely societal outcomes such as sustainable development, human rights, gender parity, and alleviation of poverty. We do so in three ways. First, we propose the need for a new, see through taxonomy for knowledge-based innovation as we transition from the material industries (e.g., textiles, plastic, cement, glass) dominant in the 20(th) century to the anticipated knowledge industry of the 21st century. If knowledge is the currency of the present century, then it is sensible to adopt an approach that thoroughly examines scientific knowledge, starting with the production aims, methods, quality, distribution, access, and the ends it purports to serve. Second, we explain that this knowledge trajectory focus on innovation is crucial and applicable across all sectors, including public, private, or public-private partnerships, as it underscores the fact that scientific knowledge is a co-product of technology, human values, and social systems. By making the value systems embedded in scientific design and knowledge co-production transparent, we all stand to benefit from sustainable and transparent science. Third, we appeal to the global health community to consider the necessary qualities of good governance for 21st century organizations that will embark on developing essential diagnostics. These have importance not only for science and knowledge-based innovation, but also for the ways in which we can build open, healthy, and peaceful civil societies today and for future generations.

    Previous literature has shown that basic body awareness therapy (BBAT) may be an effective treatment for fibromyalgia syndrome (FMS). This study constitutes the first case study evaluating internet-based BBAT for FMS. The purpose of this case study was to describe the feasibility and preliminary outcomes of an internet-based BBAT training for a total of 8 weeks in three patients with FMS. The patients underwent a synchronous individual internet-based BBAT training. Outcomes were assessed using Fibromyalgia Impact Questionnaire Revised, Awareness-Body-Chart, Short-Form McGill Pain Questionnaire (SF-MPQ), and plasma fibrinogen level. These measures were administered at baseline and after the treatment. Patient satisfaction with the treatment was evaluated using a structured questionnaire. At the post-treatment evaluation, each patient showed improvements in all outcome measures. All patients had clinically significant changes in Fibromyalgia Impact Questionnaire Revised. The SF-MPQ total score in Patients 1 and 3 exceeded the minimal clinically important difference. All patients' pain severity exceeded the minimal clinically important difference for Visual Analogue Scale (SF-MPQ). Besides, we found some benefits in body awareness and the level of dysautonomia. At the end of the treatment, patient satisfaction with the programme was very high. Based on this case study, the application of internet-based BBAT seems feasible and promising for clinical benefits.
