RESUMO
PURPOSE: To comprehend the complex relationship between symptoms and health-related quality of life (HRQoL) in patients with diffuse glioma, we applied symptom network analysis to identify patterns of associations between depression, cognition, brain tumor-related symptoms, and HRQoL. Additionally, we aimed to compare global strength between symptom networks to understand if symptoms are more tightly connected in different subgroups of patients. METHODS: We included 256 patients and stratified the sample based on disease status (preoperative vs. postoperative), tumor grade (grade II vs. III/IV), and fatigue status (non-fatigued vs. fatigued). For each subgroup of patients, we constructed a symptom network. In these six networks, each node represented a validated subscale of a questionnaire and an edge represented a partial correlation between two nodes. We statistically compared global strength between networks. RESULTS: Across the six networks, nodes were highly correlated: fatigue severity, depression, and social functioning in particular. We found no differences in GS between the networks based on disease characteristics. However, global strength was lower in the non-fatigued network compared to the fatigued network (5.51 vs. 7.49, p < 0.001). CONCLUSIONS: Symptoms and HRQoL are highly interrelated in patients with glioma. Interestingly, nodes in the network of fatigued patients were more tightly connected compared to non-fatigued patients. IMPLICATIONS FOR CANCER SURVIVORS: We introduce symptom networks as a method to understand the multidimensionality of symptoms in glioma. We find a clear association between multiple symptoms and HRQoL, which underlines the need for integrative symptom management targeting fatigue in particular.
RESUMO
BACKGROUND: Clostridium tetani is a gram-positive spore-forming bacterium that produces toxins and grows under anaerobic conditions. Infections with this bacterium can lead to local or generalised forms of tetanus. CASE DESCRIPTION: An 83-year-old man presented to the acute cardiac care unit with a painful left arm and jaw. Because the patient had a hypertonic left arm and was unable to open his mouth fully, the neurologist was consulted. The patient had been to the emergency department 9 days earlier for an infected wound after falling in the garden. He had not been actively or passively immunised against tetanus at that time. On inquiry, it appeared that the patient had also not been vaccinated as a child. We made a clinical diagnosis of tetanus. The patient was admitted and treated with tetanus immunoglobulin, metronidazole, diazepam and painkillers. He was also administered tetanus toxoid and the wound was cleaned. After 1 month and 7 months, the patient was again administered tetanus toxoid. CONCLUSION: Patients with a wound that may have come into contact with road grime, dirt or manure, should always be asked for their vaccination status, especially people from high-risk groups, such as the elderly.
