72% and 19.63%, respectively. After adjustment for potential confounding variables, multivariate analysis showed associations of CMD with female gender (OR=2.72) and work (OR=1.70).

In the present study, a high number of cases of CMD were observed among the studied adolescents. Female gender and work history in the last year were negatively and independently associated with the presence of CMD.

The influence of frailty on the elderly, especially those with chronic diseases of the respiratory system, is highly significant. Frailty is particularly more common in patients with chronic obstructive pulmonary disease (COPD). Frailty and COPD share many risk factors and pathophysiological mechanisms. As a comprehensive interventional method for chronic respiratory diseases, pulmonary rehabilitation is an important basic measure for the management of patients with COPD. Sulbactam pivoxil cell line Frailty in these patients can be reversed using pulmonary rehabilitation by targeting five components of the frailty phenotype at the entry point. The present review discusses the benefits of pulmonary rehabilitation in patients with COPD complicated by frailty and provides a theoretical basis for pulmonary rehabilitation treatment in this population. In addition, the timing of pulmonary rehabilitation is also addressed, with the prefrail stage being the "golden" period. The implementation of pulmonary rehabilitation must vary among individuals, and individualized treatment strategies will help maximize benefits.

This study aimed to determine the relationship between rs17576 (MMP-9) polymorphism and increased cancer risk in a Brazilian breast cancer cohort.

This study included 141 women (71 breast cancer patients and 70 controls without breast cancer) who donated 3 mL of their peripheral blood for genomic DNA extraction. This DNA was then genotyped using a real-time polymerase chain reaction.

The AG (rs17576) genotype was identified in 26 (18.43%) participants in the case group and in 22 (15.60%) participants in the control group (p=0.274), while the GG genotype was identified in ten (7.09%) participants in the case group and in one (0.70%) participant in the control group (p<0.003 - OR (95% CI) 13.13 (1.73, 593.08). No significant difference in the incidence rates was observed for AG or GG rs17576 genotypes in premenopausal women, p=0.813 and p=0.556, respectively. However, in postmenopausal women, the AG genotype was shown to occur in 14 (22.5%) participants in the case group and in 4 (6.45%) participants in the control (p<0.043), while GG genotype occurred in eight (12.90%) of the individuals in the case group and in none of the individuals in the control group (p<0.006).

In this study, the MMP-9 rs17576 GG polymorphic variant was shown to be significantly associated with breast cancer risk in premenopausal women, while the AG and GG genotypes were associated with increased cancer risk in postmenopausal women.

Imaging diagnosis of cervical lymphadenopathy has conventionally used ultrasonography. Shear wave elastography (SWE) is a recent ultrasound technological advancement that has shown promise in the important medical problem of differentiating between benign and malignant cervical lymph nodes based on quantitative measurements of elasticity modulus. However, widely varying elasticity modulus metrics and regions-of-interest (ROIs) were used in existing studies, leading to inconsistent findings and results that are hard to compare with each other.

Using a large dataset of 264 cervical lymph nodes from 200 patients, we designed a study comparing three elasticity modulus metrics (Emax, Emean, and standard deviation-SD) with three different ROIs to evaluate the effect of such selections. The metric values were compared between the benign and malignant node groups. The different ROI and metric selections were also compared through receiver operating characteristics curve analysis.

For all ROIs, all metric values were significantly different between the two groups, indicting their diagnostic potential. This was confirmed by the ≥0.80 area under the curve (AUC) values achieved with these metrics. Different ROIs had no effect on Emax, whereas all ROIs achieved high performance at 0.88 AUC. For Emean, the smallest ROI focusing on the area of the highest elasticity achieved the best diagnostic performance. In contrast, the larger ROIs achieved higher performances for SD.

This study illustrated the effect of elasticity modulus and ROI selection on the diagnostic performance of SWE on cervical lymphadenopathy. These new findings help guide relevant future studies and clinical applications of this important quantitative imaging modality.

Evaluate the cognitive function and its relationship with balance, history of falls, and fear of falling in the elderly.

We evaluated 250 elderly persons aged at least 60 years, who answered a sociodemographic questionnaire about the occurrence of falls in the last year. The cognitive function, balance, and fear of falling were assessed using the Mini-Mental State Examination (MMSE), Berg Balance Scale (BBS), and Falls Efficacy Scale (FES-I) scores, respectively. Participants were allocated into two groups based on the Mini-Mental State Examination (MMSE) score, the Group with Possible Cognitive Decline (GPCD) and the group with no cognitive decline (GNCD). We performed Student's t-test and Pearson's correlation for independent samples.

The Group with Possible Cognitive Decline (GPCD) showed lower balance (p=0.003) and greater fear of falling (p=0.008) (BBS=50.98±4.68; FES-I=26.06±8.78) compared to the GNCD (BBS=52.53±3.047; FES-I=23.21±7.74).

Elderly persons with cognitive decline have lower balance, greater fear of falling, and greater recurrence of falls.
