Objective To assess possible changes in leptin and ghrelin secretion due to etanercept in juvenile idiopathic arthritis (JIA). Methods 50 patients with JIA and 16 age-matched controls were enrolled into this prospective, cross-sectional study. Serum leptin, total and acyl ghrelin were measured in addition to white blood cell (WBC) and lymphocyte counts. Results 25 patients received etanercept and 25 conventional therapies (including methotrexate) for JIA. There was no difference between treatment and control groups in leptin or ghrelin levels and no evidence of a relationship between leptin and ghrelin in patients with JIA. In all children with JIA there was a correlation between leptin and body mass index (BMI). However, compared with children in the conventional treatment group, children in the etanercept group showed a positive correlation between total ghrelin and BMI and those with a low BMI showed a negative correlation between acyl ghrelin and BMI. Conclusion No differences in leptin and ghrelin concentrations were found when patients with JIA and controls were compared or when patients who received etanercept were compared with those who received conventional treatment for JIA.

Abstract Background: Tibial rotation accompanying sagittal movement contains the phenomenon of screw-home movement of the knee, which plays an important role in knee stability during extension. This study aimed to investigate the alteration of screw-home movement in patients with knee osteoarthritis (OA).Methods: Participants (n =67) in this cross-sectional study were outpatients in the department of orthopedics of a general hospital and included patients with knee OA (n=31) and asymptomatic control subjects (n=36).Knee kinematic data were measured using an inertial measurement unit. The total tibial rotation was obtainedduring knee sagittal movement. The acquired angle of tibial rotation was divided into four periodseach extension and flexion. The total tibial rotation and the variation of each period were compared between the OA and control groups.Results: Significant differences arose between the OA and control groups in the total tibial rotation during knee extension and flexion(P< 0.001).The variation of tibial rotation was also significantly different between groups for all periods (P< 0.001; knee extensionat 70° to 45°,P = 0.014).Conclusions: We found a reduction in the total tibial rotation and loss of the screw-home movement in the unloaded OA knee. To normalize the screw-home movement, it is necessary to promote proper articular movement of the knee joint and suppress the hyperexcitability of the medial muscles.

Abstract Introduction. Changes in thyroid hormone level can affect the cardiovascular system. The aim of this study was to show how the Tpeak -Tend (Tpe) interval, which is a new marker of ventricular arrythmia, is affected in patients who have become euthyroid following Levothyroxine treatment for hypothyroidism, as this has not been examined previously in literature. Materials and Methods. This, cross-sectional study included a total of 119 females aged 18-45 years, separated into 3 groups as hypothyroid, euthyroid and control groups. For evaluation of the QTc and Tpe intervals, examination on precordial V5 lead was made of all the ECGs taken routinely on presentation of the patients. Results. The Tpe and QTc intervals of the hypothyroid group were determined to be significantly prolonged compared to those of the euthyroid and control groups (p < 0.001) and the values of the euthyroid and control groups were similar. A positive correlation was determined between TSH levels and Tpe and QTc intervals. Tpe interval AUC = 0.801 (%95 CI: 0.719 – 0.884) was higher than that of QTc AUC = 0.689 (%95 CI: 0.591 – 0.786). Conclusions. The Tpe duration was evaluated in respect of the risk of arrythmia in hypothyroid patients. In patients who had become euthyroid, the Tpe interval was found to be similar to that of healthy individuals and was more predictive than QTc. In the light of these findings it can be recommended that measurement of the Tpe interval should be preferred to QTc as a marker of the arrythmogenic effect in hypothyroid patients.

Autoimmune thyroiditis (AIT) is the most prevalent autoimmune endocrine disease, with a higher incidence in women than in men. Immunological abnormalities may lead to the impairment of ovarian folliculogenesis; however, whether the presence of AIT affects immunological microenvironment in follicles remains controversial. We performed a cross-sectional study including 122 patients, aged 20–40 years, who underwent IVF/ICSI treatment owing to isolated male or tube factor infertility. Patients were divided into AIT and control groups according to clinical presentation, thyroid function, and thyroid autoantibody measurements. Follicular fluid was collected and the distribution of cytokines/chemokines in follicular fluid was measured by flow cytometry using multiplex bead assays between the two groups. Based on differences in levels of intrafollicular chemokines and cytokines between the AIT and control groups, the relevant inflammatory cascade was further demonstrated. Among the 12 chemokines analyzed, three (CXCL9, CXCL10, and CXCL11) showed significantly elevated levels in the follicular fluid of patients with AIT. Among the 11 cytokines detected, compared with those in the control group, significantly higher levels of IFNγ were observed in patients with AIT. IFNγ dose-dependently stimulated the expression and secretion of CXCL9/10/11 in cultured primary granulosa cells. The percentage of CXCR3+ T lymphocytes was significantly elevated in the follicular microenvironment of patients with AIT. We concluded that the IFNγ-CXCL9/10/11-CXCR3+ T lymphocyte inflammatory cascade is activated in the follicular microenvironment of patients with AIT. These findings indicate that a considerable immune imbalance occurred in the follicular microenvironment of patients with AIT.

Objective: to verify the association between seminal quality and seminal transferrin (ST) level and fertility index in patients undergoing chronic hemodialysis (CH). Material and methods: This is a cross-sectional study in a group of 60 men (case) undergoing CH for more than 6 months, and a group of 30 healthy men (control), aged 18-60 years, without clinical or laboratory signs of infection/inflammation. Spermiogram was performed, fertility index (FI) was calculated and ST and sex hormones (SH) levels were measured, including follicle-stimulating hormone, luteinizing hormone, total testosterone, and prolactin. Results: All individuals were eugonadal. No differences for age (49.47 ± 5.56, 47.90 ± 6.2, p = 0.22) were observed between cases and controls, whereas there were significant differences between the individuals in the case and control groups with respect to the mean FI (p = 0.000), seminal parameters (SP) (p = 0.000), and ST levels (40.12 ± 08.25 vs 73.32 ± 06.8, p = 0.000). ST levels were correlated with FI (r = 0.787, p = 0.00) and SP (motility: r = 0.857, p = 0.000; vitality: r = 0.551, p = 0.000; density: r = 0.850, p = 0.000; normal morphology: r = 0.386, p = 0.000). Linear regression model showed relationship of ST levels with total sperm motility (R2 = 0.701; p = 0.000) and and FI (R2 = 0.569; p = 0.000). Conclusions: Our results suggest that seminal quality is associated with ST levels and FI and that it can be used the initial investigation of subfertility/infertility of patients undergoing chronic hemodialysis..

Current medical guidelines consider COVID-19 pregnant women a high-risk group. Physiological gestation down-regulates the immunological response to maintain "maternal-fetal tolerance"; hence, a SARS-CoV-2 infection constitutes a potentially threatening condition to both the mother and the fetus. To establish the immune profile in pregnant COVID-19+ patients a cross-sectional study was conducted. Leukocyte immunophenotype, mononuclear leukocyte response to polyclonal stimulus, and cytokine/chemokine serum concentration were analyzed in pregnant fifteen COVID-19+ and control groups (fifteen non-pregnant COVID-19+, and thirteen pregnant COVID-19- women). Pregnant COVID-19+ patients exhibit lower percentages of monocytes HLA-DR+ compared with control groups. Nevertheless, pregnant COVID-19+ women show a higher percentage of monocytes CD39+ than controls. Furthermore, a higher concentration of TNF-alfa, IL-6, MIP1b, and IL-4 was observed within the pregnant COVID-19+ group. Our result shows that pregnant women express immunological characteristics that potentially mediate the immune response in COVID-19.

Objective: This study was designed to analyze the BCG vaccination status and compare the immune globulins levels in thehousehold contacts of tuberculous patients with non contacts of unexposed healthy peoples. Place: Gulab Devi Hospital, Post GraduateMedical Institute and Defense Housing Authority Lahore. Study design: Cross sectional study. Materials and Methods: Investigationslike ESR were done and the sera of 200 persons included in the study were tested for anti tuberculous antibodies by ELISA. BCGvaccination present or absent and scars were positive or negative in both groups were included. Results: The combined serologicalpositivity of the household contacts was 65.8% and for non-contacts was 34.1%. BCG scars were mostly absent in the householdcontacts as well as in non-contacts; But statistically IgG and IgA were present significantly by higher number in the household contacts ascompared to non-contacts, where as no significant difference in the IgM levels. These immunoglobulins status were compared with BCGscars in both study and control groups. The results were analyzed by SPSS version 14. Conclusions: Household contacts of tuberculosispatients are more susceptible to tuberculosis as compared to the non-contacts, as shown by positive and negative status ofantituberculous antibodies in the house hold contacts. More over BCG vaccination has no significant role in humoral evaluation.

Cough, an important respiratory symptom, predominantly involves the brainstem and the urge-to-cough (UTC) is modulated by the cerebral cortex. Lewy body disease is associated with decreased cough reflex sensitivity and central respiratory chemosensitivity. Additionally, the insula, associated with the UTC, shows decreased activation and atrophy in dementia with Lewy bodies (DLB). We investigated the relationships between cognition and cough reflex and the UTC and compared the differences in responses of patients with DLB and other dementia subtypes. We conducted a cross-sectional study within a geriatric ward of a university hospital involving elderly patients diagnosed with Alzheimer’s disease (AD), DLB, or non-dementia (controls). The cough reflex sensitivities were estimated based on the lowest concentrations of inhaled citric acid that could induce ≥2 coughs (C2) or ≥5 coughs (C5). Subjects were asked to rate the UTC based on the threshold concentrations (Cu) using the modified Borg scale. C2, C5 and Cu were negatively correlated with cognitive function in female participants but not in males (p < 0.01). The cough reflex sensitivities expressed as C2 and C5 were significantly higher in the DLB group than in the AD and control groups (p < 0.01 adjusted for gender). The UTC threshold expressed as Cu was also significantly higher in the DLB group, while the UTC log-log slope was less responsive in the DLB group than in the other groups. The cough reflex sensitivity and perceived UTC deteriorated in the DLB group more than in the other groups. This result might be valuable in treating patients with DLB.

Background Correlations between clinical and quantitative measures of pain sensitivity are poor, making it difficult for clinicians to detect people with pain sensitivity. Clinical detection of pain sensitivity is important because these people have a different prognosis and may require different treatment. Objective The purpose of this study was to investigate the relationship between clinical and quantitative measures of pain sensitivity across individuals with and without neck pain. Methods This cross-sectional study included 40 participants with chronic neck pain and 40 age- and sex-matched controls. Participants underwent quantitative sensory testing of cold pain thresholds (CPTs) and pressure pain thresholds (PPTs). Clinical tests for pain sensitivity were the ice pain test and the pressure pain test. All tests were undertaken at standardized local (neck and upper trapezius muscles) and remote (wrist and tibialis anterior muscles) sites. Median and interquartile range (IQR) were calculated for neck pain and control groups, and parametric and nonparametric tests were used to compare groups. Correlation coefficients were calculated between quantitative and clinical measures. Results There were significant differences for clinical and quantitative measures of cold and pressure sensitivity between the neck pain and control groups (eg, CPT neck pain group: median=22.31°C, IQR=18.58°C; control group: median=5.0°C, IQR=0.74°C). Moderate-to-good correlations were found between the clinical ice pain test and CPT at all sites (.46 to .68) except at the wrist (.29 to .40). Fair correlations were found for the clinical pressure pain test and PPT (−.26 to −.45). Psychological variables contributing to quantitative measures of pain sensitivity included catastrophization, sleep quality, and female sex. Limitations Clinical pressure pain tests were not quantitatively standardized in this study. Conclusions The ice pain test may be useful as a clinical correlate of CPT at all sites except the wrist, whereas the pressure pain test is less convincing as a clinical correlate of PPT.

Background: Parasitology is a course filled with many complicated terminologies. In this study, a guide was designed to facilitate the learning of parasitology. More precisely, an annual educational calendar of medical parasitology was designed based on the weeks of education and its effectiveness was assessed in university students of medical sciences. Materials and Methods: This cross-sectional study included 174 students who were randomly divided into two intervention and control groups. At the baseline, the students were tested with a questionnaire at the beginning of each teaching session and the end of the intervention. In addition, another questionnaire was used to compare the attitude and satisfaction of students in two groups. Finally, the scores of the students were entered in SPSS 16 for analysis. Results: The results of parametric tests showed that the mean scores of laboratory and medical students during several tests in different sessions were significantly different in the two groups. Conclusion: The educational calendar is a new method in medical education, especially in the field of medical parasitology. This calendar as an educational supplement, emphasizes on students’ active learning and contributes to improving the quality of teaching the parasitology course in addition to meeting their educational needs.

Abstract Purpose: To evaluate the epithelial and stromal thicknesses of conjunctiva and cornea in psoriatic patients with anterior segment optical coherence tomography (AS-OCT),Methods: In this cross-sectional study, 61 patients with psoriasis and 42 age-matched, healthy individuals were enrolled. The epithelial and stromal thicknesses of both inferotemporal bulbar conjunctiva and central cornea were measured using AS-OCT. Results: Both the Tear break-up time and Schirmer-1 test values were significantly lower in the psoriasis group compared with the controls (p<0.05). The epithelial thickness of conjunctiva and cornea did not differ between psoriasis and control groups. (p>0.05) The central corneal stroma was significantly thicker in the psoriasis group (p=0.04). PASI was positively correlated with the thickness of central cornea stroma (r=0.442, p=0.006) in the nail psoriasis group. Conclusions: Psoriasis is not associated with altered epithelial thicknesses of the cornea and conjunctiva. It is accompanied by the stromal thickening of the cornea without conjunctival stromal involvement.
