The Effect of Enhanced Recovery After Surgery Protocol on Surgical Site Infections in Liver Transplantation.

Background: Liver surgeries are treatment modalities that require careful pre- and postoperative follow-up for both the surgeon and the patient. Infections are the leading causes of morbidity and mortality after liver transplantation. Infections are the most frequent cause of death between 30 and 180 days after liver transplantation. We aimed to investigate the effect of the Enhanced Recovery After Surgery (ERAS) protocol on the prevention of infections in liver transplant patients. Patients and Methods: The study included patients who underwent liver transplantation in Ataturk University Organ Transplantation Center between 2017 and 2022. Two patient groups with and without ERAS were formed. Blood and urine cultures were collected retrospectively, and those with positive blood cultures for bacteremia were recorded as infection development. The development of infection between the two groups was statistically compared. Also, all patients' length of intensive care stay, length of hospital stay, and duration of antibiotic use were recorded. These parameters were compared between both groups. Results: There was a statistically significant difference between the two groups in terms of infection development (p: 0.01). There was a statistically significant difference between the two groups in terms of duration of antibiotic use and length of hospital stay (Mann-Whitney U test; p: 0.00, p: 0.04, respectively). There was no statistically significant difference between the two groups in terms of length of intensive care stay. Conclusion: We concluded that the introduction of an ERAS protocol was associated with fewer infections, thus shortening the duration of antibiotic therapy and length of hospital stay, although the standardization of the protocols is difficult, especially in liver transplants.

Temporal Trends in the Epidemiology of HIV in Turkey.

OBJECTIVE: The aim of this study was to analyze the temporal trends of HIV epidemiology in Turkey from 2011 to 2016. METHODS: Thirty-four teams from 28 centers at 17 different cities participated in this retrospective study. Participating centers were asked to complete a structured form containing questions about epidemiologic, demographic and clinical characteristics of patients presented with new HIV diagnosis between 2011 and 2016. Demographic data from all centers (complete or partial) were included in the analyses. For the cascade of care analysis, 15 centers that provided full data from 2011 to 2016 were included. Overall and annual distributions of the data were calculated as percentages and the Chi square test was used to determine temporal changes. RESULTS: A total of 2,953 patients between 2011 and 2016 were included. Overall male to female ratio was 5:1 with a significant increase in the number of male cases from 2011 to 2016 (p<0.001). The highest prevalence was among those aged 25-34 years followed by the 35-44 age bracket. The most common reason for HIV testing was illness (35%). While the frequency of sex among men who have sex with men increased from 16% to 30.6% (p<0.001) over the study period, heterosexual intercourse (53%) was found to be the most common transmission route. Overall, 29% of the cases presented with a CD4 count of >500 cells/mm3 while 46.7% presented with a CD4 T cell count of <350 cells/mm3. Among newly diagnosed cases, 79% were retained in care, and all such cases initiated ART with 73% achieving viral suppression after six months of antiretroviral therapy. CONCLUSION: The epidemiologic profile of HIV infected individuals is changing rapidly in Turkey with an increasing trend in the number of newly diagnosed people disclosing themselves as MSM. New diagnoses were mostly at a young age. The late diagnosis was found to be a challenging issue. Despite the unavailability of data for the first 90, Turkey is close to the last two steps of 90-90-90 targets.

Myxoma developing after open heart surgery: is radiofrequency ablation responsible for the formation of the tumor?

34-year-old male with history of recurrent atrial fibrillation (AF) and mitral stenosis, status post radiofrequency ablation (RFA) and prosthetic mitral valve replacement two years earlier was admitted with prosthetic valve thrombosis for redo mitral valve surgery. During the surgery, a 2 x 1.5 x 1 cm mass was identified on the interatrial septum, attached to the edge of tricuspid valve's septal leaflet by a stalk. The mass was excised and histological evaluation revealed myxoma. It is accepted that myxomas can develop after cardiac trauma. It is known that RFA for AF increases the risk of thrombus or endocarditis in the atrium. Herein, we report a myxoma case where we think the heat energy caused by RFA might have triggered the development of the tumor.

Effects of diabetes on cytokines and oxidative organ injury in a rat model of sepsis.

We aimed to investigate how Diabetes Mellitus (DM) affects myeloperoxidase activity, antioxidant status, and lipid peroxidation using biochemical approaches in heart, liver, and lung and serum cytokine analyses, such as interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) in rat with sepsis induced by a cecal ligation and puncture-induced (CLP) sepsis. The rats were divided into four groups: control group, diabetic group, sepsis group, and diabetic+sepsis group. DM was induced in the male Wistar albino rats by administration of alloxan. Polymicrobial sepsis was induced by cecal ligation and two-hole puncture. After alloxan administration, all groups of rats were allowed to recover for 1 month. CLP model was applied after 1 month recovery to group 3 and 4. IL-6 and TNF-α, were measured. Effects of antioxidant defenses on the DM and/or sepsis process, the antioxidant levels superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) were evaluated in heart, lung and liver tissues. The oxidant levels, such as lipid peroxidation (LPO) and myeloperoxidase (MPO) levels were also evaluated in tissues. We demonstrated DM to augment the level of oxidant and proinflammatory cytokines in lung, liver, and heart and also to exacerbate oxidative injury as assessed by increased LPO and MPO, and decreased GSH and SOD levels in a sepsis model. DM increased levels of proinflammatory cytokines while DM also resulted in significantly increased levels of proinflammatory cytokines following CLP. DM-increased plasma proinflammatory cytokines levels correlated positively with tissue oxidant levels, such as MPO and LPO levels in a rat abdominal sepsis model, based on CLP, which resulted in the exacerbation of oxidative organs injury.

A halo in the heart during coronary angiography: calcified left ventricular aneurysm with thrombus formation.

A 74-year-old man presented with chest pain and dyspnoea at the cardiology outpatient clinic. His past medical history included an anterior myocardial infarction in 2008. In the coronary angiogram, a 'halo image' was seen right after the injection of the contrast agent, and it corresponded with the location of the left ventricular aneurysm. A calcified left ventricular aneurysm with mural thrombus was confirmed with cardiac MRI and a CT scan.
