Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

[Q]: Abstract: Thermal injuries lead to changes in both the cell-mediated and humoral responses of the patient. This study was undertaken to assess these responses in the post-burn period and also to see if bacterial infection altered these responses. It has been concluded that alterations in the cell-mediated and humoral immune responses following thermal injuries are altered by infection and consequently are also important in the healing process.

[Q]: Abstract: Following nephrectomy and acute potassium loading, animals previously maintained on a high potassium diet have a smaller increment in plasma potassium than do animals on a control diet. The mechanism of this "extrarenal potassium adaptation" is not known. To explore the role of potassium depletion in this process, we studied rats adapted to either a high potassium (HK) or control (C) diet. When dietary potassium was withdrawn, urinary potassium losses in HK rats greatly exceeded those in C rats for at least two days, leading to greater potassium depletion in HK than C animals. A smaller increment in plasma potassium in HK compared to C rats was seen only after prolonged fasting preceded nephrectomy and acute potassium loading. Correction of potassium depletion incurred during fasting abolished extrarenal potassium adaptation. We conclude: after withdrawal of dietary potassium, urinary potassium losses are much greater in HK than in C rats; if the duration of dietary potassium deprivation is sufficient, these urinary potassium losses will cause potassium-adapted animals to paradoxically become more potassium depleted than controls; and this paradoxical potassium depletion may be responsible for extrarenal potassium adaptation.

[Q]: Abstract: The occurrence of fever during various blood purification methods was evaluated in a retrospective study. It could be demonstrated, that patients treated chronically by conventional hemodialysis experience six times more febrile episodes than patients on chronic hemofiltration (4.84% versus 0.81%). Since many of the increased temperatures could not be explained by conventional means, it has to be assumed that the treatment itself caused the fever, possibly activating the monocyte hormone interleukin 1. It is of further note that there was no difference in the magnitude of the temperature due to septicaemia or to no obvious cause. This finding necessitates in our opinion an early antibiotic therapy in those cases where fever develops without clear explanation.
