Background: The inflammatory bowel disease questionnaire (IBDQ) is a frequently used outcome parameter in clinical trials. Whereas the validity and reproducibility of the IBDQ have been extensively studied, there are limited data on its short-term responsiveness and cutoff values for remission and partial clinical response.
Methods: The IBDQ score and its bowel (BD), systemic (SysD), emotional (ED), and social (SocD) dimensions were tested for responsiveness in a cohort of 224 patients with Crohn's disease (CD) treated with infliximab for refractory luminal disease. Changes in the IBDQ score and its dimensions 4 weeks after therapy were analyzed and correlated with changes in the Crohn's Disease Activity Index (CDAI). The responsiveness ratios of the IBDQ and its dimensions were analyzed. Using regression line with DeltaCDAI, the cutoff values for the IBDQ remission and response were calculated.
Results: Overall, there was a good correlation between the CDAI and IBDQ at week 0 (correlation coefficient, 0.69; P < .001) and week 4 (-0.76; P < .001) and change after 4 weeks (0.74; P < .001). The correlation coefficients for DeltaCDAI and changes in BD, SysD, ED, and SocD were 0.753, 0.552, 0.620, and 0.631, respectively; all P < 0.001. The responsiveness ratios for DeltaIBDQ, BD, SysD, ED, and SocD were 2.6, 2.1, 1.9, 1.7, and 1.9, respectively. Regression line for the IBDQ (r = -0.76, P < .001) resulted in a cutoff value for remission of 168 points and for DeltaIBDQ resulted in a cutoff value of 22 and 27 points for clinical improvement based on DeltaCDAI > or = -70 and > or = -100 points.
Conclusions: The IBDQ is a responsive instrument for reflecting quick change in the quality of life of patients with CD. Cutoff values for the IBDQ remission and partial response were 168 and > or = 27 points.

Background: The DCDDaily-questionnaire (DCDDaliy-Q) evaluates children's performance and participation in motor-based activities of daily living (ADLs), meeting diagnostic criterion B for developmental coordination disorder (DCD). Currently, there are no Chinese translations or growth references available. Thus, this study aimed to culturally adapt, validate, and establish reference norms for the DCDDaily-Q in Chinese children.

Objective: Diffusion tensor imaging (DTI) showed promising results in diagnosing upper limb neuropathies, but its value in patients with foot drop due to peroneal neuropathy has not yet been investigated. We aim to establish reference values for DTI metrics of the healthy peroneal nerve and to evaluate differences in DTI metrics between patients and healthy controls.
Methods: Diffusion-weighted images (DWI) from 22 pathological nerves, 14 asymptomatic patients' nerves and 65 healthy peroneal nerves were processed for quantitative assessment of fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity and mean diffusivity.
Antifungal Susceptibility of Dermatophyte Isolates from Patients with Chronic and Recurrent Dermatophytosis.

Background: The widespread occurrence of chronic and recurrent dermatophytosis has significantly affected the quality of life for patients in India and beyond. Identifying the causative dermatophytes and understanding their antifungal susceptibility can aid clinicians in tailoring effective antifungal therapies.
Materials And Methods: Patients with chronic and recurrent dermatophytosis were enrolled, and conventional fungal cultures were conducted on skin scrapings.

Background: Traumatic brain injury (TBI) is a significant public health issue worldwide that affects millions of people every year. Cognitive impairment is one of the most common long-term consequences of TBI, seriously affect the quality of life. We aimed to develop and validate a predictive model for cognitive impairment in TBI patients, with the goal of early identification and support for those at risk of developing cognitive impairment at the time of hospital admission.

Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia (CAP) in children and can lead to severe complications, including respiratory failure. A retrospective analysis of 2084 children diagnosed with CAP and treated in our hospital from January 2022 to January 2023 was conducted. A comprehensive dataset of patient demographics, clinical symptoms, and laboratory findings was initially assembled.
