          Abstract

          Objectives:

          To determine the hematological indices and ratios derived from them in patients with fibromyalgia and to correlate the scores of Fibromyalgia Impact Questionnaire Revised (FIQR) with the ratios.

          Methods:

          This case control study was performed in the College of Pharmacy at Hawler Medical University in Erbil-Iraq, from November 2016 to June 2017, and it included 40 healthy subjects (Group I) and 150 newly diagnosed FM (Group II). The American College of Rheumatology -10 (ACR-10) diagnostic criteria were used in the diagnosis of FM. The scores of the Revised Fibromyalgia Questionnaire Impact (FIQR), and tender points were calculated, and the hematological indices and ratios were determined.

          Results:

          Group II showed significantly higher mean values of hematological indices and the ratios of neutrophil to lymphocyte (NLR), derived neutrophil to lymphocyte (dNLR) and platelet to lymphocyte (PLR). Group II patients have a significant higher score of FIQR. A significant correlation between the total score of FIQR with the hematological ratios (F=4.143, R=0.355, R 2=0.126, p=0.002) with a variability of 12.6%.

          Conclusion:

          We conclude that the hematological indices are significantly altered and they are significantly correlated with the total score of fibromyalgia impact questionnaire revised.

          The Revised Fibromyalgia Impact Questionnaire (FIQR): validation and psychometric properties

          Introduction The Fibromyalgia Impact Questionnaire (FIQ) is a commonly used instrument in the evaluation of fibromyalgia (FM) patients. Over the last 18 years, since the publication of the original FIQ, several deficiencies have become apparent and the cumbersome scoring algorithm has been a barrier to widespread clinical use. The aim of this paper is to describe and validate a revised version of the FIQ: the FIQR. Methods The FIQR was developed in response to known deficiencies of the FIQ with the help of a patient focus group. The FIQR has the same 3 domains as the FIQ (that is, function, overall impact and symptoms). It differs from the FIQ in having modified function questions and the inclusion of questions on memory, tenderness, balance and environmental sensitivity. All questions are graded on a 0–10 numeric scale. The FIQR was administered online and the results were compared to the same patient's online responses to the 36-Item Short Form Health Survey (SF-36) and the original FIQ. Results The FIQR was completed online by 202 FM patients, 51 rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) patients (31 RA and 20 SLE), 11 patients with major depressive disorder (MDD) and 213 healthy controls (HC). The mean total FIQR score was 56.6 ± 19.9 compared to a total FIQ score of 60.6 ± 17.8 (P < 0.03). The total scores of the FIQR and FIQ were closely correlated (r = 0.88, P < 0.001). Each of the 3 domains of the FIQR correlated well with the 3 related FIQ domains (r = 0.69 to 0.88, P < 0.01). The FIQR showed good correlation with comparable domains in the SF-36, with a multiple regression analysis showing that the three FIQR domain scores predicted the 8 SF-36 subscale scores. The FIQR had good discriminant ability between FM and the 3 other groups; total FIQR scores were HC (12.1 ± 11.6), RA/SLE (28.6 ± 21.2) and MDD (17.3 ± 11.8). The patient completion time was 1.3 minutes; scoring took about 1 minute. Conclusions The FIQR is an updated version of the FIQ that has good psychometric properties, can be completed in less than 2 minutes and is easy to score. It has scoring characteristics comparable to the original FIQ, making it possible to compare past FIQ results with future FIQR results.

            The Fibromyalgia Impact Questionnaire (FIQ): a review of its development, current version, operating characteristics and uses.

            The Fibromyalgia Impact Questionnaire (FIQ) was developed in the late 1980s by clinicians at Oregon Health & Science University in an attempt to capture the total spectrum of problems related to fibromyalgia and the responses to therapy. It was first published in 1991 and since that time has been extensively used as an index of therapeutic efficacy. Overall, it has been shown to have a credible construct validity, reliable test-retest characteristics and a good sensitivity in demonstrating therapeutic change. The original questionnaire was modified in 1997 and 2002, to reflect ongoing experience with the instrument and to clarify the scoring system. The latest version of the FIQ can be found at the web site of the Oregon Fibromyalgia Foundation (www.myalgia.com/FIQ/FIQ). The FIQ has now been translated into eight languages, and the translated versions have shown operating characteristics similar to the English version.

              Derived neutrophil to lymphocyte ratio and monocyte to lymphocyte ratio may be better biomarkers for predicting overall survival of patients with advanced gastric cancer

              Background and objectives Preoperative systemic inflammatory response and nutritional status play important roles in the tumorigenesis, progression, and prognosis of gastric cancer (GC). This research is designed to investigate the prognostic value of the biomarkers including the neutrophil to lymphocyte ratio (NLR), derived neutrophil to lymphocyte ratio (dNLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI) in predicting overall survival in patients with GC. Methods A total of 1,990 consecutive GC patients who underwent gastrectomy from 2007 to 2011 were enrolled and divided into high level and low level based on the optimal cut-off points for NLR, dNLR, MLR, PLR, and PNI, respectively. The clinicopathological characteristics of the two levels were comparatively analyzed. Overall survival analysis was executed using these biomarkers and clinicopathological characteristics. Results The number of metastatic lymph nodes, distant metastasis, American Joint Committee on Cancer TNM stage, radicality, tumor size, metastatic lymph nodes ratio, ascites, and Hb were all significantly associated with NLR, dNLR, MLR, PLR, and PNI. All of these five biomarkers were closely associated with overall survival in univariate analyses, but only dNLR and MLR were significant in multivariate model. dNLR and MLR can be bonded to predict survival, but whether separate or together, dNLR and MLR were mainly significant in advanced stages. Conclusion Although preoperative NLR, dNLR, MLR, PLR, and PNI in peripheral blood proved significant prediction of prognoses of postoperative GC patients, dNLR and MLR may be better biomarkers for predicting overall survival, especially in advanced GC patients.
