Push and Pull Factors of Why Medical Students Want to Leave Türkiye: A Countrywide Multicenter Study

Phenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Türkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Türkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Türkiye in 2022. Besides participants' migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Türkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22-1.54) times more likely to emigrate. The push factor that was related to emigration intention was the "working conditions in the country" (OR: 1.89, 95% CI: 1.56-2.28) whereas the "social environment/lifestyle abroad" was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45-2.06). In addition, the quality problem in medical schools also had a significant impact on students' decisions (OR: 2.20, 95% CI: 1.83-2.65). Insights: Although the percentage of those who want to emigrate "definitely" was at the same level as in the other developing countries, the tendency to migrate "permanently" was higher in Türkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians.

An evaluation of matrix metalloproteinase-9 (Mmp-9) and tissue inhibitor metalloproteinase-1 (Timp-1) Serum levels and the Mmp-9/Timp-1 Ratio in Covid-19 patients

Background

The progression of COVID-19 has different clinical presentations, which raises a number of immunological questions.

Objectives

This study aimed to investigate MMP-9 and TIMP-1 levels in patients diagnosed with COVID-19 and whether the MMP-9/TIMP-1 ratio is associated with lung involvement in COVID-19.

Methods

This study was conducted with 192 patients and 45 healthy controls. ELISA was used to measure the MMP-9 and TIMP-1.

Results

The MMP-9 and TIMP-1 levels of the patients were found to be higher than those of the controls. MMP-9 and TIMP-1 were detected more in patients with lung involvement on chest CT scans than in those with no lung involvement on chest CT scans. A comparison of lung involvement levels revealed no difference was found between the groups. The MMP-9/TIMP-1 ratio was 5.8 in the group with lung involvement on chest CT scans and 6.1 in the group without lung involvement on chest CT scans. No difference was found between the two groups. A comparison with respect to lung involvement levels showed that the MMP-9/TIMP-1 ratio difference was found between the groups.

Conclusion

Diagnostic and treatment methods targeting MMP-9 activity or neutrophil activation may be important in predicting lung involvement in COVID-19 and directing clinical outcomes.

Smartphone Addiction and Its Relationship with Depression in University Students: A Cross-Sectional Study

Aim: This study was aimed to determine the risk factors and at-risk prevalence for smartphone addiction, and also investigate the relationship between smartphone addiction and depression in Necmettin Erbakan University students. Methods: This cross-sectional study was conducted on 509 students who were enrolled in Necmettin Erbakan University, between March 1 and June 15, 2017. Together with the questionnaire form which was prepared by researchers after literature review, Smartphone Addiction Scale-Short Version and Beck Depression Inventory were applied to the participants under supervision. Results: At-risk prevalence for smartphone addiction in the participants was 46.4%. There were statistically significant differences between the at-risk prevalence for smartphone addiction and gender, age, class they attended, daily smartphone use time, to use or not to use social network sites on smartphone, most used social network sites on smartphone, place of residence and most frequently purpose of smartphone usage. Of the participants, 31.4% were at risk for depression. There was a statistically significant positive correlation between the at-risk prevalences for smartphone addiction and depression at a weak level. Conclusion: This study results showed that there are considerable numbers of university students who are at risk for smartphone addiction and depression. For more accurate results about smartphone addiction and depression relationship further clinical researches should be done. Keywords: addiction, depression, mobile phone, students, universities

Patient Knowledge, Attitudes, and Behaviors Associated with Organ Donation

Background

This study compared the knowledge, attitudes, and behaviors associated with organ donation and transplantation among patients undergoing dialysis versus those visiting family health centers (FHCs).

Material/Methods

This cross-sectional study included patients undergoing hemodialysis treatment at the Meram Medical Faculty and those visiting FHCs in Meram district for other reasons.

Results

The study participants were 128 individuals visiting FHCs and 111 patients undergoing dialysis. Of these, 169 individuals (70.7%) correctly answered the question “What is brain death?” The knowledge level in the FHC group was higher than that in the dialysis group. Less than half of the individuals indicated willingness to donate an organ. Furthermore, subjects in the dialysis group were more likely than those in the FHC group to answered “no” to the question “Would you be willing to donate an organ to someone of a different religion?”

Conclusions

Positive attitude towards organ transplantation and donation does not necessarily reflect positive behavior these 2 groups.

Is serum high-mobility group box 1 (HMGB-1) level correlated with liver fibrosis in chronic hepatitis B?

BACKGROUND

High-mobility group box 1 (HMGB1), identified as an alarmin molecule, was shown to have a role in virus-triggered liver injury. We aimed to evaluate the association between serum levels of HMGB1 and liver fibrosis.

METHOD

This cross-sectional case-control study included 189 chronic hepatitis B (CHB) patients and 51 healthy controls. All patients underwent liver biopsy and modified Knodell scoring system used to determine the fibrosis level in CHB patients. Serum HMGB1 levels were determined with enzyme-linked immunosorbent assay (ELISA).

RESULTS

Mean serum HMGB1 levels of patients (58.1 ± 54.7) were found to be higher than those of the control group (7.1 ± 4.3) (P = .001). HMGB1 levels of patients with advanced-stage fibrosis (stage 4 and 5) were detected to be higher than those of patients with early-stage fibrosis (stage 1-3). However, this difference was not statistically significant (P > .05). Albumin levels of fibrosis 3 and 4 patients were lower than fibrosis 1 and 2 patients. ALT, HBV DNA, and AFP levels of fibrosis 5 patients were significantly higher than fibrosis 1 and 2 patients, and their platelet and albumin levels are lower than fibrosis 1 and 2 patients (P < .001). In a logistic regression model, fibrosis levels were correlated with ALT values and inversely correlated with albumin levels.

CONCLUSION

In this study, we demonstrated that serum HMGB1 levels increase in the early course of liver injury and this increase is not correlated with severity of the liver damage.

Impaired Thiol-Disulfide Balance in Acute Brucellosis

The objective of this study was to examine a novel profile: thiol-disulfide homeostasis in acute brucellosis. The study included 90 patients with acute brucellosis, and 27 healthy controls. Thiol-disulfide profile tests were analyzed by a recently developed method, and ceruloplasmin levels were determined. Native thiol levels were 256.72 ± 48.20 μmol/L in the acute brucellosis group and 461.13 ± 45.37 μmol/L in the healthy group, and total thiol levels were 298.58 ± 51.78 μmol/L in the acute brucellosis group and 504.83 ± 51.05 μmol/L in the healthy group (p < 0.001, for both). The disulfide/native thiol ratios and disulfide/total thiol ratios were significantly higher, and native thiol/total thiol ratios were significantly lower in patients with acute brucellosis than in the healthy controls (p < 0.001, for all ratios). There were either positive or negative relationships between ceruloplasmin levels and thiol-disulfide parameters. The thiol-disulfide homeostasis was impaired in acute brucellosis. The strong associations between thiol-disulfide parameters and a positive acute-phase reactant reflected the disruption of the balance between the antioxidant and oxidant systems. Since thiol groups act as anti-inflammatory mediators, the alteration in the thiol-disulfide homeostasis may be involved in brucellosis.

Monitoring and treatment results of 88 HBsAg-positive pregnant women

Approximately 5% of all women in the world are HBsAg-positive. Chronic hepatitis B is a problem in women of reproductive age. This paper assessed 88 HBsAg-positive pregnant women, of whom 11 began treatment during pregnancy and five became pregnant while receiving treatment. The files of HBsAg-positive pregnant women were reviewed between January 2010 and December 2013-retrospectively. From these 88 pregnant women, 72 did not receive any treatment during their pregnancy, 11 began treatment during their pregnancy, and five became pregnant while receiving treatment. Nine of these 11 pregnant women were given tenofovir disoproxil fumarate and two of them lamivudine. Ten babies of the 11 mothers that began treatment during their pregnancy were healthy, but one was lost due to preterm birth. Of the five patients who became pregnant while receiving treatment, the treatments of four women were discontinued and they were monitored during their pregnancies because mild-moderate (less than stage 3) fibrosis was found in their liver biopsy results. It is important to screen all pregnant women for hepatitis B and to assess those found HBsAg-positive. It is possible to protect both the mother and baby using appropriate approaches.

Serum Levels of Annexin A2 as a Candidate Biomarker for Hepatic Fibrosis in Patients With Chronic Hepatitis B

BACKGROUND

Hepatologists have studied serologic markers of liver injury for decades. Annexins are a prominent group of such markers and annexin A2 (AnxA2) is one of the best characterized annexins. AnxA2 inhibits HBV polymerase among other functions. Its expression is up-regulated in regenerative hepatocytes.

OBJECTIVES

To determine if serum AnxA2 level has a role in estimating liver damage in chronic HBV infection and investigate whether AnxA2 levels correlate with hepatic fibrosis.

PATIENTS AND METHODS

This study included 173 patients with chronic hepatitis B (CHB) and 51 healthy controls. Liver fibrosis was graded histologically on liver biopsy samples. Blood samples were taken from patients during biopsy and serum AnxA2 levels were measured with ELISA.

RESULTS

In a group of adult patients with CHB, AnxA2 values were far higher than those of the control group (P = 0.001). When we assessed AnxA2 levels based on fibrosis stages, serum AnxA2 levels of patients with early stage fibrosis (stages 1 - 3) were significantly higher than those of patients with advanced stage fibrosis (stages 4 - 5; P = 0.001).

CONCLUSIONS

AnxA2 is a useful biomarker for early stage fibrosis in patients with CHB.

Are bone morphogenetic protein-7 (BMP-7) serum levels correlated with development of hepatic fibrosis?

INTRODUCTION

Bone morphogenetic protein-7 (BMP-7) is a key protein in organogenesis and liver development. The protein has been studied in the context of liver fibrosis and regeneration. The aim of the present study was to explore any possible association between fibrosis levels (as revealed by liver biopsy) and serum BMP-7 levels.

METHODOLOGY

A total of 189 patients with chronic hepatitis B and 51 healthy controls were enrolled in the study.

RESULTS

The study group contained 120 (63.5%) males and 69 (36.5%) females, and the control group contained 25 males (49.0%) and 26 females (51%). In general, serum BMP-7 values of patients were higher than those of controls (p = 0.001). Serum BMP-7 values of patients with liver fibrosis of stages 1, 2, 3, or 4 were higher than control values (all p values = 0.01), but the serum BMP-7 levels of patients with stage 5 fibrosis were similar to that of controls. Associations between fibrosis stage and the serum levels of BMP-7, ALT, HBVDNA, platelets, and albumin were all statistically significant (p = 0.001). The AUROC for the BMP-7 level in advanced stage fibrosis was found to be 0.23. The data were analyzed using the binary logistic regression analysis (backward stepwise method) and BMP-7, HBVDNA, and platelet levels were found to be risk factors associated with fibrosis (p values 0.031, 0.040, and 0.001, respectively).

CONCLUSIONS

BMP-7 may play anti-inflammatory and anti-fibrogenic roles in the pathogenesis of chronic hepatitis B infection.

Evaluation of the relation between hepatic fibrosis and basic laboratory parameters in patients with chronic hepatitis B fibrosis and basic laboratory parameters

BACKGROUND

The hepatitis B virus is an important healthcare problem. According to current clinical practice, a liver biopsy is required for the diagnosis and treatment of chronic liver disease. However, a liver biopsy is an invasive, inconvenient procedure, which requires an expert pathologist opinion. Therefore requirement of biochemical tests, which are considered to indicate hepatic fibrosis and may be repeated easily, increases gradually today.

OBJECTIVES

This study evaluated the correlation between hepatic fibrosis and routine laboratory values in patients with chronic hepatitis B.

PATIENTS AND METHODS

The files of 456 patients with CHB (chronic hepatitis B) who were referred to the infectious diseases and clinical microbiology clinic between January 2009 and March 2012 were screened retrospectively. Liver biopsy samples were examined according to Ishak scoring. Laboratory parameters and histopathology reports were recorded, and correlations between the fibrosis grade and laboratory parameters were analyzed.

RESULTS

There were 320 male and 136 female patients, with a mean age 36.7 ± 12.1 years. According to liver biopsy results, a low fibrosis score (stage 0-2) was detected in 281 patients (61.6%), and a high fibrosis score (stage 3-5) was detected in 175 patients (38.4%). Patients with a high fibrosis score had significantly higher ALT (alanine amino transferase), AST (aspartate aminotransferase), and HBV-DNA values and a significantly lower platelet count compared with those with a low fibrosis score (P = 0.001, 0.001, 0.025, and 0.001, respectively). A positive correlation was detected between the fibrosis score and age, BMI, HAI, ALT, and AST values, and a negative correlation was detected between the fibrosis score and albumin and platelet counts. In the regression analysis performed to evaluate the factors associated with high-stage fibrosis, fibrosis was determined to be associated with thrombosis, ALT, and gender. The results of the regression analysis demonstrated that the risk of fibrosis was 4.6 fold higher in men.

CONCLUSIONS

According to the results obtained in our study, advanced age, higher BMI, AST, ALT, and HBV-DNA levels, and low albumin and platelet levels are correlated with advanced fibrosis in patients with CHB.
