Background: Assessment of functional status is vital for proper therapy and rehabilitation programs in chronic obstructive pulmonary disease (COPD) patients. Traditionally, 6 min walk test (6MWT) has been used but it by itself may not reflect the total functional status in these patients as it poorly correlates to the disease severity. A sit-to-stand test (STST) has been proposed as a better alternative to 6MWT but to test their ability to stand from the squatting position, i.e., a squat-to-stand test (SqTST) will be more appropriate in rural patients.
Material And Methods: All patients, diagnosed to have stable COPD, after exclusion of asthma and other respiratory or nonrespiratory diseases were evaluated by applying 6MWT, STST, and SqTST in them. Data so obtained were statistically analyzed.
Results: Ninety patients and twenty healthy controls were studied. Sixteen, 24, 23, and 27 of the patients were classed as COPD risk category A, B, C, and D, respectively. The mean post bronchodilator forced expiratory volume in 1st second (PB FEV1) and body mass index (BMI) were significantly lower in category D as compared to the rest. The cutoff values for 6MWT, STST, and SqTST were derived as 184M, 11, and 07, respectively. 6MWT correlates poorly to disease severity (P = 0.109) but there was a strong correlation between disease severity and SqTST and STST (P = 0.000).
Conclusion: SqTST is a feasible and effective tool to assess functional status of COPD patients residing in rural areas. BMI is an important surrogate marker of the functional status in these patients.

Key Laboratory of Gastroenterology and Hepatology, Shanghai Institute of Digestive Disease, Division of Gastroenterology and Hepatology, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.
Background And Aim: Linaclotide is effective in relieving constipation-predominant irritable bowel syndrome symptoms. However, few studies focus on the efficacy of linaclotide for overlapping symptoms of functional dyspepsia among irritable bowel syndrome patients. This study aimed to assess the efficacy of linaclotide compared with lactulose in patients with functional dyspepsia and constipation-predominant irritable bowel syndrome overlap.

Institute of Technology for Carbon Neutrality, Shenzhen Institute of Advanced Technology, CAS, Shenzhen, 518 055, China.
Micro/nano manipulation of single nanowire has emerged as a popular direction of study in the field of nanotechnology, with promising applications in cutting-edge technologies such as device manufacturing, medical treatment, and nanorobotics. The synthesis of nanowires with controllable length and diameter makes them meet various micro/nano manipulation demands. As manipulation techniques have advanced, including the use of optical tweezers, electric and magnetic fields, mechanical control, and several more control methods, they have demonstrated unique advantages in different application fields.

This perspective positions rewilding as a novel approach to ecosystem restoration, emphasising the restoration of natural processes to create self-willed ecosystems. Central to European rewilding is the de-domestication of cattle and horses to act as functional analogues of the extinct aurochs and wild horses. This de-extinction pathway shifts the focus from the loss of species to the loss of their ecological roles caused by human actions commencing millennia ago.

Introduction: Migrant workers constitute a significant portion of China's workforce, and their health directly affects labor supply and economic stability. Health vulnerability plays a crucial role in shaping the well-being of migrant workers, yet its determinants, particularly the impact of temperature change, remain underexplored. This study, based on the socio-ecological model, investigates how temperature variations influence the health vulnerability of migrant workers in China.

School of Humanities, Southeast University, Nanjing, China.
Purpose: To investigate the mediating effect of financial toxicity on stigma and self-perceived burden in patients with liver cancer after surgery.
Methods: Using a convenience sampling method, 236 postoperative liver cancer patients treated at a tertiary hospital in Nanjing from April 2024 to July 2024 were selected for the study. Questionnaires were administered, including a general information survey, the Social Impact Scale (SIS), the Self-Perceived Burden Scale for Cancer Patients (SPBS-CP), and the Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy Version 2 (COST-FACIT-V2).
