ABSTRACT
OBJECTIVE: Parkinson's disease (PD) as a neurodegenerative disorder characterized by a reduction in both the quantity and functionality of dopaminergic neurons. This succinctly highlights the central pathological feature of PD and its association with dopaminergic neuron degeneration, which underlies the motor and non-motor symptoms of the disease. This study aims to elucidate the nuances of apparent diffusion coefficient (ADC) changes in different cerebral regions by after the bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) surgery of PD, as well as to investigate their potential interactions with the motor and neuropsychiatric spectrum. METHODS: Patients who underwent STN-DBS surgery for PD between 2017 and 2019 were included in this study. The results of diffusion magnetic resonance imaging (MRI), Unified Parkinson Disease Rating Scale (UPDRS) III scores, Beck and Hamilton depression tests were recorded before and at the 3rd month of postoperative stimulation. The data obtained were evaluated with the Wilcoxon signed rank test. Result of the statistical tests were within the 95â¯% confidence interval and p values were significant below 0.05. RESULTS: Our study was conducted with a total of 13 patients, 8 men and 5 women. As a result of measurements made in a total of 32 different regions, especially in the motor and neuropsychiatric areas of the brain, an increase in ADC values was found in all areas. ADC changes of eight localizations such as left corpus callosum, right corona radiata, left corona radiata, hippocampus, right insula, left superior cerebellar peduncle, left caudate nucleus and left putamen were statistically significant. UPDRS III scores improved by 57â¯% (p <0.05), and Beck and Hamilton depression scores by 25â¯% and 33â¯%, respectively (p> 0.05). CONCLUSIONS: This article implicate that bilateral STN-DBS surgery potentially exerts beneficial effects on both motor and neuropsychiatric symptomatology in individuals with PD. We believe that this therapeutic mechanism is hypothesized to involve modulation of diffusion alterations within distinct cerebral tissues.

BACKGROUND: Diabetes foot infection is a very important public health problem that causes serious health problems, mortality, and high health expenditures, and is one of the most important complications of diabetes mellitus. There are concerns that approaches such as limited personal visits to doctors, avoidance of hospitals, and restrictions on nonemergency surgical procedures during the coronavirus disease of 2019 pandemic pose a threat to those with diabetic foot problems, including diabetic foot ulcers (DFUs), ischemia, and infection, resulting in increased limb loss and mortality. METHODS: This multicenter, retrospective, cross-sectional study was conducted in 14 tertiary care hospitals from various regions of Turkey. A total of 1,394 patient records were evaluated, 794 of which were between January 1, 2019, and January 30, 2020 (prepandemic [Pre-P]), and 605 of which were between February 1, 2020, and February 28, 2021 (pandemic period [PP]). RESULTS: During the PP, diabetic foot patient follow-up decreased by 23.8%. In addition, the number of hospitalizations attributable to DFU has decreased significantly during the PP (P = .035). There was no difference between the groups regarding patient demographics, medical history, DFU severity, biochemical and radiologic findings, or comorbidities, but the mean duration of diabetes mellitus years was longer in patients in the Pre-P than in those in the PP (15.1 years versus 13.7 years). There was no difference between the two groups in terms of major complications such as limb loss and mortality, but infection recurrence was higher in the PP than in the Pre-P (12.9% versus 11.4%; P < .05). The prevalence of nonfermentative gram-negative bacteria as causative agents in DFU infections increased during the PP. In particular, the prevalence of carbapenem-resistant Pseudomonas spp. increased statistically during the PP. CONCLUSIONS: The rapid adaptation to the pandemic with the measures and changes developed by the multidisciplinary diabetic foot care committees may be the reasons why there was no increase in complications because of DFU during the pandemic in Turkey.

AIMS: Structured management programmes deliver optimized care in heart failure patients and improve outcome. We examined the feasibility of including patients with migration background speaking little or no German in a heart failure management programme. METHODS AND RESULTS: After adaption of script material and staff to Turkish language we aimed to recruit 300 Turkish and 300 German (control group) patients within 18 months using the operational basis of a local heart failure management programme for screening, contact and inclusion. Of 488 and 1,055 eligible Turkish and German patients identified through screening, 165 Turkish (34%) and 335 German (32%) patients consented on participation (p = 0.46). General practitioners contributed significantly more of the Turkish (84%) than of the German patients (16%, p<0.001). Contact attempts by programme staff were significantly less successful in Turkish (52%) than in German patients (60%, p = 0.005) due to significantly higher rate of missing phone numbers (36% vs 25%), invalid address data (28% vs 7%) and being unreachable by phone more frequently (39% vs 26%, all p<0.001). Consent rate was significantly higher in successfully contacted Turkish (63%) compared to German patients (50%, p<0.001). CONCLUSION: The inclusion of Turkish minority patients into a heart failure management programme is feasible with higher consent rate than in Germans. However, effort is high due to inherent logistic adaptions and barriers in identification and contacting of patients. TRIAL REGISTRATION: DRKS00007780.

OBJECTIVE: The aim of this study is to evaluate the effect of ejaculation on serum total, free and complex prostate-specific antigen (PSA) levels and their effect on biopsy decisions. MATERIAL AND METHODS: Our study includes 47 men older than 45 years with symptomatic benign prostatic hyperplasia (BPH). Patients' PSA levels were under 2.5 ng/mL, and there were no known conditions to preclude ejaculation. Eight patients with similar demographic, and clinical characteristics were chosen as a control group. With three days of sexual abstinence, blood samples were drawn for the measurement of baseline PSA levels, and then the patients were told to ejaculate. One, 5, 24 and 72 hours after ejaculation, serum total, free and complexed PSA levels were measured. Serum PSA sampling was performed at the same intervals in the control group without ejaculation. RESULTS: The mean age of the patients was 59.13±1.38 years in the study group, and 63.75±3.13 years in the control group. The mean international prostate symptom scores (IPSS) were 11.78±1.12 and 11.63±3.32 in the study, and the control groups, respectively. The mean baseline total, free, and complexed PSA values were 1.07±0.09, 0.31±0.03, and 0.71±0.08 ng/mL, respectively. In the study group, total PSA value was found to be 1.29±0.12 ng/mL (p=0.008) at first hour after ejaculation, and this change was statistically significant when compared with baseline values. Mean total PSA level rose up to 1.28±0.13 ng/mL (p=0.05) by the 5(th) hour after ejaculation, but this change was not statistically significant relative to the baseline values. Mean free PSA level rose after the first hour postejaculation to 0.37±0.04 ng/mL (p=0.01) and after the fifth hour postejaculation to 0.37±0.04 ng/mL (p=0.002), and these changes were statistically significant relative to the baseline values. There were no statistically significant changes at the other sampled times as for the total, free or complexed PSA serum levels. When all three values were considered individually, in only 2.12% of the patients, biopsy decisions could be affected by the elevation in PSA levels. CONCLUSION: When the PSA value is borderline with respect to biopsy decisions, the effect of ejaculation on serum PSA levels may be clinically important. In these patients, ejaculation must be questioned, and repeated. PSA levels should be evaluated 24 hours after ejaculation. There were no statistically significant changes in the levels of complex PSA values. Further studies are needed to clarify the relationship between complexed PSA and ejaculation.
