Desirability Optimization Models to Create the Global Healthcare Competitiveness Index.

The aim of this research is to enhance desirability optimization models to create a global healthcare competitiveness index (GHCI) covering 53 countries with gross domestic product per capita (GDP PC) of over $10,000. The GHCI is defined as an index that reveals the progress and quality of the healthcare systems in countries providing their patients with easier access opportunities to healthcare services within the scope of this work. Methods of statistical analysis have been adopted together with optimization models and techniques in this research. The optimum and feasible values of the factors considered influential on objective functions have been determined as the basis of healthcare expenditure (HE) and GHCI in those relevant countries. Those released optimum outcomes are displayed between 0.64 and 0.66 in terms of desirability value. The GHCI values of those aforementioned countries range from 0 to 6. The computed average of the GHCI values of those countries is estimated as 2.4758. Finally, GHCI values of 53 countries have been calculated to set the current basis of desirability optimization models. These findings will be deemed as the basic essence of those prospective theories to be established for the future researches to constitute a new index to measure the competitiveness of healthcare systems in various countries all over the world.

Upregulation of SIRT1 gene in gastric adenocarcinoma.

BACKGROUND/AIMS: SIRT1 gene overexpression is reportedly associated with cancer development, via the triggering of DNA repair impairment, and cell proliferation. The study aimed to investigate SIRT1 expression in patients with gastric cancer and its correlations with the clinical and pathological characteristics of the disease. MATERIALS AND METHODS: All patients (64 patients) who underwent gastric biopsy and were diagnosed with gastric adenocarcinoma and signet ring cell carcinoma between January 2011 and December 2013 were enrolled in the study, and patients with benign gastric biopsy were enrolled in the control group (34 patients). The previously prepared gastric tissues were collected from the pathology department, and SIRT1 gene expressions were evaluated in the gastric tissues of all study patients. Patients were subclassified according to their demographic, clinical, and pathologic features, and the patient and control groups were compared. RESULTS: Sixty-four patients were included in the study (25 females and 39 males). The mean age of the patients was 66±1 (range: 33-88) years. The SIRT1 gene 2' Average delta cycle threshold (CT) value was 0.102 in the control group, whereas it was 0.292 in the patients with gastric cancer (relative risk: 2.86; p=0.014). The SIRT1 gene was upregulated in all tumor stage subgroups except stage I, female patients, young patients (<45 years), and corpus and cardia tumor subgroups compared to the control group. CONCLUSION: SIRT1 gene overexpression is associated with gastric adenocarcinoma, and it can be argued that SIRT1 gene upregulation is associated with unfavorable gastric adenocarcinoma prognosis.

Splenectomy proportions are still high in low-grade traumatic splenic injury.

OBJECTIVE: The spleen is the most vulnerable organ in blunt abdominal trauma. Spleen-preserving treatments are non-operative management with or without splenic angioembolization, partial splenectomy, and splenorrhaphy. The aim of the present study was to determine the rate of SPTs and to evaluate the usefulness of Injury Severity Score after traumatic splenic injury. MATERIAL AND METHODS: We searched our institution's database between May 2012 and December 2015. Patients' clinicopathological features, surgeon's title, type of treatment, admission and discharge dates, duration of surgery, intensive care unit requirement, and Glasgow Coma Scale were recorded. RESULTS: The mean age of patients was 33.36±11.58 years. Of the 33 patients, 26 (78.8%) were males, and 7 (21.2%) were females. Thirty (90.9%) had total splenectomy (TS), and 3 (9.1%) had spleen preserving treatment (2 Nonoperative management and 1 partial splenectomy). No fatal hemorrhage developed after nonoperative management. Exitus rates were 5/30 (15.1%) and 0/3 in the total splenectomy and spleen preserving treatment groups, respectively. Of the 18 hemodynamically stable patients, only 2 (11.1%) had spleen preserving treatment. Of the 19 patients with grade I-III splenic injury, only 3 (15.8%) had spleen preserving treatment. For academic and non-academic surgeons, spleen preserving treatment rates were 3/11 (27.3%) and 0/22 (0%), respectively (p<0.05). Injury severity score and mean arterial pressure, number of transfusions, control hematocrit, and GCS had statistically significant relationships. CONCLUSIONS: Spleen preserving treatment proportions were low after traumatic splenic injury. Following trauma, guidelines will not only improve spleen preservation rates but also improve the overall health status of the patients and it will also prevent complications of splenectomy.

Adherence to vaccination recommendations after traumatic splenic injury.

BACKGROUND: The occurrence of a serious infection called overwhelming post-splenectomy infection (OPSI) increases more than 50 times in patients who have hyposplenia. The aim of this study was to investigate the adherence to vaccination recommendations after traumatic splenic injury. METHODS: We identified patients who underwent total splenectomy due to abdominal trauma between May 2012 and March 2016. We recorded the clinical, laboratory, and pathological features of the patients. We calculated the vaccination proportions before discharge, after discharge, and final. RESULTS: Twenty-seven patients underwent total splenectomy. For the vaccination status before discharge, after discharge, and final, the number of patients who received all the three vaccinations were 0 (0%), 0 (0%), and 8 (18.5%) and those who received none were 13 (48.2%), 11 (40.8%), and 9 (33.4%), respectively. The data of 17 patients were available for developing OPSI. The median follow-up time was 17.8 (4.4-41.2) months, and no OPSI cases were observed. CONCLUSION: Adherence to vaccination recommendations remains still low. Establishing a vaccination tracking system and following vaccination recommendations will be helpful to prevent serious infections, such as OPSI, after traumatic splenectomy.

Proton magnetic resonance spectroscopy of periventricular white matter and hippocampus in obstructive sleep apnea patients.

BACKGROUND: The purpose of this study was to diagnose the hypoxic impairment by Magnetic resonance spectroscopy (MRS), an advanced MR imaging technique, which could not be visualised by routine imaging methods in patients with obstructive sleep apnea (OSA). MATERIAL/METHODS: 20 OSA patients and 5 controls were included in this prospective research. MRS was performed on these 25 subjects to examine cerebral hypoxemia in specific regions (periventricular white matter and both hippocampi). Polysomnography was assumed as the gold standard. Statistical analysis was assessed by Mann-Whitney U test and Receiver operating characteristics (ROC) curve for NAA/Cho, NAA/Cr and Cho/Cr ratios. RESULTS: In the periventricular white matter, NAA/Cho ratio in OSA patients was significantly lower than in the control group (p<0.05). There were no statistical differences between the OSA and the control group for NAA/Cho, NAA/Cr and Cho/Cr ratios for both hippocampal regions. Additionally, Cho/Cr ratio in the periventricular white matter region of OSA group was higher than in the control group (p<0.05). CONCLUSIONS: Hypoxic impairment induced by repeated episodes of apnea leads to significant neuronal damage in OSA patients. MRS provides valuable information in the assessment of hypoxic ischemic impairment by revealing important metabolite ratios for the specific areas of the brain.

Amebic perforation of small bowel: an unexpected localization of a fatal complication.

The intestinal protozoan parasite E. histolytica is the causative organism responsible for human amebiasis and amebic dysentery. Although it is primarily an infection of the colon, it may also be spread by hematogenous path to other organs, especially the liver. In general, the clinical spectrum of colorectal amebiasis ranges from the state of asymptomatic carrier to severe fulminant necrotizing colitis with bleeding and perforation. Here we present an extremely rare case of necrotizing amebiasis of small bowel with a fatal outcome (Fig. 1, Ref. 4). Full Text (Free, PDF) www.bmj.sk.

Public awareness of, attitudes toward, and understanding of epilepsy in Isparta, Turkey.

The social stigma attached to epilepsy very often constitutes a considerable problem and much private grief for patients and their relatives. This study was aimed at investigating "perceivers"' awareness of, attitudes toward, and understanding of epilepsy in Isparta, Turkey. Using a questionnaire survey, we interviewed, face-to-face, a random sample of 582 persons older than 18, excluding persons with epilepsy or those with relatives who had epilepsy. Eighty-one percent of respondents had heard of epilepsy, 47% knew a person with epilepsy, and 54% had seen an epileptic seizure. Somewhat less knowledgable were the elderly and less educated individuals. Attitudes toward social acceptance and employment of persons with epilepsy were generally negative, especially to children's associations and marriage. Twelve percent considered epilepsy as a form of insanity. Although understanding of epilepsy was favorable, the results indicate that there exists significant discrimination against persons with epilepsy, and there is a need to implement public education campaigns.
