Background: In certain patients with pancreatic and biliary cancer, chemotherapy may relieve tumour-related symptoms, improve quality of life and possibly prolong survival. The extent of these improvements is not completely known in spite of the extensive use of this treatment modality. The aim of this study was to estimate any gain in the quantity and quality of life produced by chemotherapy in patients with pancreatic and biliary cancer.
Patients And Methods: Between January 1991 and February 1995, 90 eligible patients with pancreatic or biliary cancer were randomized to either chemotherapy in addition to best supportive care or to best supportive care. Chemotherapy was allowed in the latter group if the supportive measures did not lead to palliation. Chemotherapy was either sequential 5-fluorouracil/leucovorin combined with etoposide (FELv) or, in elderly and poor performance patients, the same regimen without etoposide (FLv). Quality of life was evaluated with the EORTC-QLQ-C30 instrument.
Results: Mean scale scores in the QLQ-C30 improved more often/deteriorated less frequently in the chemotherapy group than in the best supportive care group. More patients in the chemotherapy group (36%, 17/49) had an improved or prolonged high quality of life for a minimum period of 4 months compared to those in the best supportive care group (10%, 4/41, P < 0.01). Overall survival was significantly longer in the chemotherapy group (median 6 vs. 2.5 months, P < 0.01). Also, the quality-adjusted survival time was longer for patients randomized to chemotherapy (median 4 vs. 1 months, P < 0.01). The effects were seen both in pancreatic and biliary cancer.
Conclusions: The results show that chemotherapy can add to both quantity and quality of life in advanced pancreatic and biliary cancer. The number of patients who benefit from treatment is, however, still limited; for this reason careful selection before, and close monitoring during, treatment are necessary.

Low and high glycemic index drinks differentially affect sleep polysomnography and memory consolidation: A randomized controlled trial.
Nutr Res

Limited research has examined the effect of meal composition on sleep. Based on previous research, we hypothesized that a low glycemic index (LGI) drink containing 50 g isomaltulose (Palatinose, GI = 32) would result in more N3 sleep, less rapid eye movement (REM) sleep, and better memory consolidation than a high glycemic index (HGI) drink containing 50 g glucose (GI = 100). Healthy males (n = 20) attended the laboratory on three occasions at least a week apart (one acclimatization night and two test nights).

Rationale: Bilateral gluteus medius contractures in adults are rare in clinical practice, with only a few cases reported. These contractures may result from repeated intramuscular injections during childhood. Understanding the clinical manifestations, diagnostic process, treatment, and outcomes can provide insights into effective management strategies.

Osteoarthritis (OA) is a chronic joint condition affecting millions worldwide, characterized by the gradual degeneration of joint cartilage, leading to pain, stiffness, and functional impairment. Although the pathogenesis of OA is not fully understood, the roles of inflammation, metabolic dysregulation, and biomechanical stress are increasingly recognized. Current treatments, including pharmacotherapy, physical therapy, and surgical interventions, aim to alleviate symptoms and improve quality of life, yet they face limitations and challenges.

Background: Parkinson's disease is a progressive neurodegenerative disease and the care burden in informal caregivers is huge. Summarizing factors associated with the informal caregivers burden can improve our understanding of providing proactive support to informal caregivers caring for patients with Parkinson's disease (PwP) at risk, and provides evidence for clinical practice.

Preharvest sprouting (PHS) is an unfavorable trait in cereal crops that significantly reduces grain yield and quality. However, the regulatory mechanisms underlying this complex trait are still largely unknown. Here, 276 rice accessions from the 3000 Rice Genomes Project were used to perform a genome-wide association study.
