RESUMO

BACKGROUND AND AIMS: There are limited data on the comparison of body compositions between diabetic and non-diabetic patients. We aimed to compare the muscle mass and fat parameters measured by ultrasonography (USG) and dual-energy x-ray absorptiometry (DXA) between older palliative care patients with and without type 2 diabetes mellitus (DM). METHODS: We conducted a prospective, cross-sectional study. We recorded the demographics, comorbidities, blood pressures, microvascular complications, pressure injuries, ambulation and nutritional status, and laboratory parameters. We measured the handgrip strength with a hand dynamometer and anthropometric parameters. We analyzed the subcutaneous fat thickness, muscle thickness (MT), and cross-sectional area (CSA) of the rectus femoris (RF) and biceps brachii muscles by USG and the total and regional muscle mass and fat parameters by DXA. We performed a regression analysis to examine the independently associated factors of DM. RESULTS: We included 55 patients (mean age: 79.0 ± 8.0 years, 56.4%: female). 43.6% had type 2 DM. The patients with DM had significantly higher glucose and HbA1c levels and lower RFMT and RFCSA values than the patients without DM (p < 0.01, for all). The RFMT was independently associated with DM after adjusting age, sex, and body mass index (Odds ratio = 0.735, 95% confidence interval = 0.565-0.956, p = 0.022). CONCLUSION: Our study demonstrated that the RFMT might be associated with type 2 DM. This was the first study comparing the body compositions measured by USG and DXA between older diabetic and non-diabetic palliative patients with a wide range of laboratory evaluations. Longitudinal, multi-center studies are warranted to understand the underlying mechanisms.

RESUMO

BACKGROUND/AIMS: Acute pancreatitis which is characterized by pancreatic inflammation can sometimes be difficult to treat because of limited therapeutic options. The purpose of the study was to assess the effects of agmatine in the acute pancreatitis experimental rat model. MATERIALS AND METHODS: An acute pancreatitis model was created with the administration of cerulein in 40 female Sprague-Dawley rats. Agmatine was administered as a protective agent at 5 mg/kg (low dose) and 10 mg/kg (high dose). The rats were divided into 5 groups, each with 8 rats: group 1 (acute pancreatitis); group 2 (acute pancreatitis+low-dose agmatine 5 mg/kg); group 3 (acute pancreatitis+high-dose agmatine 10 mg/kg); group 4 (placebo, acute pancreatitis+saline); and group 5 (sham and saline infusion). All rats were sacrificed 24 hours after the last injection, and the levels of superoxide dismutase, interleukin-1 beta, and tumor necrosis factor-alpha were assessed in blood samples collected via cardiac puncture. Histopathological examination was performed by a pathologist, who was blind to the groups, according to the Schoenberg's pancreatitis scoring index. RESULTS: The amylase (16.67 and 37.89 U/L), glutathione peroxidase (13.62 and 18.44 ng/mL), tumor necrosis factor-α (39.68 and 64 ng/mL), interleukin-1 (484.73 and 561.83 pg/mL), and transforming growth factor-ß (110.52 and 126.34 ng/L) levels were significantly lower and superoxide dismutase (1.29 and 0.98 ng/L) and malondialdehyde (0.99 and 0.96 nmol/mL) levels were significantly higher in group 3 compared to group 1 (P < .05). Moreover glutathione peroxidase, tumor necrosis factor-α, and transforming growth factor-ß levels were lower, and malondialdehyde levels were higher in the group 3 compared to group 2 (P < .05). Although the Schoenberg's pancreatitis scoring index was not significantly different between the high- and low-dose treatment groups, rats who received high-dose treatment had significantly lower scores compared to those with acute pancreatitis group. CONCLUSION: This is the first study that evaluated the efficacy of agmatine in an experimental model of acute pancreatitis. Agmatine, an anti-inflammatory and antioxidant agent, had a protective effect in an experimental rat model of acute pancreatitis.

RESUMO

BACKGROUND: To evaluate the effect of sodium-glucose cotransporter-2 inhibitor treatment on choroidal vascular parameters in patients with type 2 diabetes mellitus (T2DM). METHODS: Twenty eyes of 20 patients with T2DM without diabetic retinopathy and 20 eyes of 20 age- and sex-matched patients as the control group were included in the study. The patients were evaluated using enhanced depth imaging optic coherence tomography before treatment and at the third month of treatment. The choroidal images were binarized into luminal areas (LAs) and stromal areas (SAs). The choroidal vascularity index (CVI) was defined as the ratio of the LA to the total circumscribed choroid area (TCA). RESULTS: The mean age of the patients was 56.65±8.41 years. The patients' mean disease duration was 6.65±5.72 years, the mean HbA1c level was 8.89±1.62%, and the mean body mass index was 33.13±4.84 kg/m2. The subfoveal TCA, subfoveal LA, subfoveal SA, total TCA, total LA, and total SA values ​​of the patient group were found to be significantly lower than those of the control group (p = 0.006, p = 0.003, p = 0.028, p = 0.001, p = 0.001, and p = 0.006, respectively). There was a significant increase in the subfoveal TCA, subfoveal LA, subfoveal SA, subfoveal CVI, total TCA, total LA, and total SA values ​​after empagliflozin treatment compared to before empagliflozin treatment (p = 0.005, p = 0.003, p = 0.021, p = 0.032, p < 0.001, p < 0.001, and p = 0.001 respectively). CONCLUSIONS: Empagliflozin provides an improvement in diabetic choroidal changes through its effect on choroidal vascularity parameters.

RESUMO

OBJECTIVES: Neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) are markers reflecting the inflammation process that can be easily calculated in the hemogram examination. In this study, we aimed to investigate the changes in NLR, PLR and MPV values ​​in patients who attempted suicide by taking drugs. METHODS: In total, 124 patients who were admitted to the emergency department after attempting suicide by taking drugs and who were followed up in the internal medicine department for observation purposes for 24-72 hours were included in the study. The study was retrospective and the data of the patients were recorded by scanning the hospital automation system. The NLR, PLR and MPV of the patients at the time of admission to the emergency department and at the time of discharge were evaluated and compared with each other. RESULTS: The NLR and PLR values ​​of the patients at admission were found to be significantly higher than those values ​​at discharge. In our study, NLR and PLR values were found to be high during the period when patients attempted suicide. CONCLUSION: The high detection of these markers of inflammation suggests that it may be a marker predictive of suicide attempt by taking medication (Tab. 4, Ref. 28).

RESUMO

BACKGROUND AND STUDY AIMS: The role of cytomegalovirus (CMV) infection for disease reactivation in ulcerative colitis (UC) patients remains controversial and diagnostic tests are yet to be standardized. We aimed to define the clinical relevance of CMV detection by mucosal polymerase chain reaction (PCR) in UC patients by comparing the clinical course of UC in CMV-treated and CMV-untreated groups in tissue CMV-PCR positive cases. PATIENTS AND METHODS: In this retrospective study, 141 patients diagnosed with moderate-to-severe UC admitted to our clinic with disease flare, colonic tissue CMV PCR was assessed. RESULTS: The median age of the study population was 39 years, and 99 (70.2%) patients were male. Eighty-eight (62.4%) patients were CMV-PCR (+) and 53 (37.6%) were CMV PCR (-). The CMV-PCR (+) and CMV PCR (-) groups showed no significant difference concerning age, sex, disease duration, site of involvement and disease activity and administered treatments. The median tissue CMV-PCR was 41,098 IU/mL (IQR:2,344.25-136,192). Thirty-four of 88 CMV-PCR (+) patients received antiviral therapy. The tissue CMV-PCR level of patients who received antiviral therapy was 124,381 IU/mL (IQR: 19,309-412,335), and it was 6,292 IU/mL (IQR: 997-71,154) in patients who did not receive antiviral therapy; (p < 0.001). Sixteen (47.1%) of 34 patients who received antiviral therapy achieved remission. Two of the non-responders underwent colectomy (one because of dysplasia and one who did not respond subsequent biologic agent either). Remaing 16 achieved remission by escalating the immunsuppresive/biologic agent therapy. CONCLUSION: CMV infection is responsible for only a minority of cases of UC flares and all are steroid-resistant cases. Most of the patients non-responsive to antiviral treatment respond to increased anti-inflammatory treatment. Hesitancy in the decision of escalating immunsuppresive treatment rather than CMV disease may be responsible for worsening disease course and increased colectomy rate in a significant number of the patients who are tissue CMV-PCR (+).

RESUMO

OBJECTIVE: We aimed to investigate the role of testosterone to estradiol ratio in predicting the effectiveness of human chorionic gonadotropin and testosterone treatments in male hypogonadism. METHODS: Thirty-six male patients with hypogonadotropic hypogonadism were included in the study. Seventeen (47.2%) patients received weekly recombinant human choriogonadotropin alpha (hCG) treatment (group-1) and 19 (52.8%) received testosterone replacement therapy (T treatment) every 21 days (group-2). Under these treatments, adequate frequency of morning erection (≥3/week), testosterone to estradiol ratio (T/E), and testicular volume changes were analyzed. RESULTS: The mean age of the patients was 28.5 ± 8.7 years. When the frequency of morning erection (≥3/week) was specified as adequate, the cut-off value for effective T/E ratio was found to be 12.0 (sensitivity 93.8%, specificity 90.0%). There was no significant difference between the treatment groups in terms of total testosterone levels, T/E ratio, or frequency of morning erections (≥3/week) (p > 0.05). However, there was a statistically significant difference between the groups in terms of median left-right testicular volume in favor of group-1 (p < 0,05). CONCLUSION: In patients with hypogonadism who are under treatment, elevated estradiol-induced erectile dysfunction symptoms may persist even if serum testosterone levels are normal. Testosterone to estradiol ratio can be used as a predictive value in the effective treatment of hypogonadotropic hypogonadism with hCG and T.
