RESUMEN
Multiple myeloma (MM) is a bone marrow malignancy characterized by plasma cell proliferation. It was aimed to investigate pentraxin 3 (PTX3) levels, oxidative/antioxidative status, and their correlation in MM. In the study, four groups were established, including newly diagnosed MM (NDMM), MM in remission (Rem-MM), relapsed/refractory MM (RRMM) patients, and a healthy control group. PTX3 levels were measured using enzyme-linked immunosorbent assay, and the total antioxidant status (TAS) and total oxidant status (TOS) were assessed with an autoanalyzer. The oxidative stress index (OSI) was calculated using the formula: OSI (arbitrary unit) = TOS (µmol H2O2 Eq/L)/TAS (mmol Trolox Eq/L) × 100. The study involved comparing PTX3, TAS, TOS, and OSI levels among these four groups. PTX3 levels were significantly elevated in NDMM and RRMM groups compared to controls and the Rem-MM group (NDMM vs control; p < 0.001, NDMM vs Rem-MM; p < 0.001, RRMM vs control; p < 0.001, and RRMM vs Rem-MM; p = 0.006). TAS was higher in NDMM and RRMM groups versus controls (p = 0.009 and p < 0.001, respectively), and TOS was higher in rem-MM group versus NDMM and control groups (p < 0.001 and p = 0.016, respectively). OSI was higher in the Rem-MM group than in NDMM and RRMM groups (p < 0.001 and p = 0.009, respectively). Multivariate analysis confirmed associations between MM groups and PTX3 levels. Receiver operating characteristic analysis revealed high specificity (90%) and sensitivity (79%) for PTX3 in NDMM at a >0.56 ng/mL cut-off value. This study suggests that PTX3 levels may have diagnostic and prognostic potential in MM and its relationship with oxidative stress requires further exploration.

PURPOSE: Opioids are widely used to treat painful vaso-occlusive crises (VOC) in sickle cell disease (SCD). However, due to opioids' significant adverse effect profiles, the search for alternative therapies continues from the past to the present. The study aimed to investigate the efficacy of acetaminophen and dexketoprofen in the treatment of painful VOC. METHODS: This study is a single-center, prospective, non-randomized, single-blinded, controlled study. The study comprised two groups: the first administered acetaminophen and dexketoprofen mixed group, while the second received them sequential group. Opioids were used in patients with persistent pain despite these analgesics. Demographic and laboratory information, pain scores, opioid requirement, dose amount, side effects, and length of hospital stay of the patients were recorded. RESULTS: The study comprised 56 (100%) patients with painful VOC, 29 (51.8%) from the mixed group, and 27 (48.2%) from the sequential group. Opioid use was seen in 16 (55.2%) patients in the mixed group and 21 (77.8%) patients in the sequential group (p = 0.074). The median amount of opioid used was significantly lower in the mixed group than in the sequential group (p < 0.001). Also, the median length of hospital stay was significantly lower in the mixed group than in the sequential group (p < 0.001). CONCLUSION: Our study suggests that administering acetaminophen and dexketoprofen in the mix for the treatment of painful VOC in patients with SCD may be a more efficient approach compared to sequential administration. This approach appears to reduce opioid usage and shorten hospital stays.

OBJECTIVE: This study investigated interleukin-10 and nitric oxide plasma levels following surgery to determine whether there is a correlation between these two variables and if different desflurane anesthesia flow rates influence nitric oxide and interleukin-10 concentrations in circulation. MATERIALS AND METHODS: Forty patients between 18 and 70 years and ASA I-II physical status who were scheduled to undergo thyroidectomy were enrolled in the study. INTERVENTIONS: Patients were allocated into two groups to receive two different desflurane anesthesia flow rates: high flow (Group HF) and low flow (Group LF). MEASUREMENTS: Blood samples were drawn at the beginning (t 0) and end (t 1) of the operation and after 24 h (t 2). Plasma interleukin-10 and nitric oxide levels were measured using an enzyme-linked-immunosorbent assay and a Griess reagents kit, respectively. Hemodynamic and respiratory parameters were assessed. RESULTS: There was no statistically significant difference between the two groups with regard to interleukin-10 levels at the times of measurement. Interleukin-10 levels were increased equally in both groups at times t 1 and t 2 compared with preoperative concentrations. For both groups, nitric oxide circulating concentrations were significantly reduced at times t 1 and t 2 compared with preoperative concentrations. However, the nitric oxide value was lower for Group HF compared to Group LF at t 2. No correlation was found between the IL-10 and nitric oxide levels. CONCLUSION: Clinical usage of two different flow anesthesia forms with desflurane may increase interleukin-10 levels both in Group HF and Group LF; nitric oxide levels circulating concentrations were significantly reduced at times t 1 and t 2 compared with preoperative concentrations; however, at 24 h postoperatively they were higher in Group LF compared to Group HF. No correlation was detected between interleukin-10 and nitric oxide levels. .
OBJETIVO: este estudo investigou os níveis plasmáticos de interleucina-10 e óxido nítrico após cirurgia para determinar se há correlação entre essas duas variáveis e se diferentes taxas de fluxo de anestesia com desflurano influenciam as concentrações de interleucina-10 e óxido nítrico na circulação. MATERIAIS E MÉTODOS: quarenta pacientes, entre 18 e 70 anos de idade, estado físico ASA I-II, programados para tireoidectomia foram incluídos no estudo. INTERVENÇÕES: os pacientes foram divididos em dois grupos para receber dois fluxos diferentes de anestesia com desflurano: fluxo alto (Grupo FA) e fluxo baixo (Grupo FB). MENSURAÇÕES: amostras de sangue foram colhidas no início (t 0 ) e final (t 1 ) da cirurgia e após 24 h (t 2 ). Os níveis plasmáticos de interleucina-10 e óxido nítrico foram medidos usando um ensaio imunossorvente ligado à enzima um estojo de reagentes de Griess, respectivamente. Os parâmetros hemodinâmicos e respiratórios foram avaliados. RESULTADOS: não houve diferença estatisticamente significante entre os dois grupos em relação aos níveis de interleucina-10 níveis nos tempos de medição. Os níveis de interleucina-10 aumentaram igualmente em ambos os grupos nos tempos t 1 e t 2 em comparação com as concentrações no pré-operatório. Em ambos os grupos, as concentrações circulantes de óxido nítrico estavam significativamente reduzidas nos tempos t 1 e t 2 em comparação com as concentrações no pré-operatório. No entanto, o valor de óxido nítrico foi menor no Grupo FA que no Grupo FB no t 2 . Não houve correlação entre os níveis de IL-10 e óxido nítrico. CONCLUSÃO: o ...
