RESUMO

BACKGROUND: Medical students face significant psychological stress, impacting their academic performance and well-being. The Systematic Assessment for Resilience (SAR) framework is designed to enhance resilience and mitigate stress among medical students, addressing the need for interventions within the assessment system in medical education. The aim of this study was to evaluate the implementation of SAR framework on medical students' resilience, anxiety, depression, burnout, and academic stress. METHODS: This study employed a quasi-experimental design with pre- and post-testing. It involved the training of course coordinators in implementing the SAR framework and its integration into the daily learning activities. Fourth-year medical students were assessed before and after the intervention using standardized measures of resilience, anxiety, depression, burnout, and academic stress. Data were analyzed using quantitative methods and thematic analysis for qualitative feedback. RESULTS: Post-intervention, students demonstrated a significant increase in resilience scores (p < 0.001) and a notable decrease in measures of anxiety, depression, and academic stress (p < 0.001). The burnout types were also statistically different (p < 0.001) except client-related burnout (p > 0.05). Qualitative feedback of the course coordinators highlighted an improved learning environment, increased coping strategies, and a more supportive academic culture. CONCLUSION: The SAR framework significantly contributes to enhancing medical students' resilience and reducing psychological distress. Its implementation suggests a promising approach to fostering a supportive educational environment that not only addresses the psychological challenges faced by medical students but also enhances their academic performance and overall well-being. Further research is warranted to explore the long-term impacts of SAR across different medical education contexts.

RESUMO

The CYP2C19 gene is frequently included in different pharmacogenomic panels tested in clinical practice, due to its involvement in the metabolism of a myriad of frequently prescribed medications. Accordingly, CYP2C19 genotyping can promote precise therapeutic decisions and avoid the occurrence of significant drug-drug-gene interactions in the clinical setting. A comprehensive examination of the role of the CYP2C19 gene in real-world medical settings is presented in this review. This review summarizes the most recent information on how genetic variants in CYP2C19 affect drug metabolism and therapeutic outcomes. It goes into the wide range of CYP2C19 phenotypes, with different degrees of metabolizing activity, and their implications for customized medication response through a review of the literature. The review also analyzes the clinical significance of CYP2C19 in several medical specialties, including cardiology, psychiatry, and gastro-enterology clinics, and illuminates how it affects pharmacological efficacy, safety, and adverse effects. Finally, CYP2C19-supported clinical decision-making is outlined, highlighting the possibility of improving therapeutic outcomes and achieving more affordable treatment options, a step towards optimizing healthcare provision through precision medicine.

RESUMO

COVID-19 exhibits diverse and systemic clinical symptoms, much like systemic autoimmune diseases, and there are notable similarities in the immune responses seen in both conditions. There are rare reports of ulcerative colitis and autoimmune hepatitis triggered by COVID-19 infection. Reported herein is a case of a previously healthy patient who was diagnosed with chronic colitis resembling ulcerative colitis, autoimmune pancreatitis, and suspected immune-mediated hepatitis (AIH-like hepatitis) 2 months after a COVID-19 infection. A 33-year-old COVID-19-vaccinated male, presented with abdominal pain, nausea, and vomiting for 2 days. He also had bloody diarrhea that persisted for 2 months after recovering from a COVID-19 infection. A diagnosis of acute pancreatitis was confirmed by markedly elevated serum amylase and lipase and a CT scan of the abdomen. Colonoscopy and histopathology findings also confirmed a diagnosis of chronic colitis resembling ulcerative colitis (Mayo Endoscopy Subscore 3). Marked improvement in bloody diarrhea was observed within 72 h of treatment with IV prednisolone. MRI of the abdomen performed due to an unresolved clinical picture of pancreatitis revealed a bulky pancreas showing delayed diffuse homogenous enhancement, findings possibly consistent with autoimmune pancreatitis. Investigation for elevated liver transaminases showed high titers of antinuclear antibodies and anti-smooth muscle (anti-actin) antibodies while viral hepatitis markers were negative. The patient had already been started on steroid therapy before the lab results were available, with rapid normalization of liver enzymes following treatment. A liver biopsy was not performed. The patient is currently on mesalazine 4 gr/day, and azathioprine 100 mg/day - oral steroids had been tapered and discontinued. Seven months after the initial diagnosis, the patient remains symptom-free. A high level of suspicion for autoimmune disorders is required when assessing patients with a history of COVID-19 infection, although diagnostic pathways remain the same, with generally good response and remission rates to conventional treatment.

RESUMO

Congenital hepatic fibrosis is part of many different malformation syndromes, of which oculo-encephalo-hepato-renal syndrome is the most common. These syndromes largely overlap, and so accurate classification of individual patients may be difficult. We present herein three syndromic siblings who were products of a consanguineous marriage. We investigated in detail at least six organ systems in these patients, namely the liver, brain, eye, kidneys, skeleton, and gonads. The common features observed in these three cases were congenital hepatic fibrosis, retinitis pigmentosa, truncal obesity, rotatory nystagmus, mental retardation, advanced myopia, and high-arched palate. The clinical dysmorphology in these patients was distinct and lacked the major features of the known syndromes associated with congenital hepatic fibrosis. Although some features of these presented cases are similar to those found in Bardet-Biedl syndrome (BBS), the absence of some major criteria of BBS (polydactyly, renal abnormality, and hypogonadism) suggests that this may be a new syndrome. All three patients remain under follow-up in the departments of Gastroenterology, Ophthalmology, and Neurology at Hacettepe University.

RESUMO

OBJECTIVE: Hashimoto's thyroiditis (HT) may affect metabolic parameters and increase predisposition to obesity. In this study, we aimed to assess the relationships among serum ghrelin concentrations, metabolic parameters, and thyroid autoimmunity in euthyroid HT patients. METHODS: The study included 48 euthyroid HT patients and 41 age- and sex-matched healthy controls. We assessed serum ghrelin, free triiodothyronine (T3), free thyroxine (T4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (anti-TPO), thyroglobulin antibody (anti-Tg), fasting blood glucose (FBG), insulin, lipid levels, and homeostasis model assessment insulin resistance (HOMA-IR) in all subjects. RESULTS: Sex distribution, mean age, and body mass index (BMI) were similar in HT patients and controls (female/male, 42/6 vs. 33/8, 46.8 ± 14.7 vs. 45 ± 12.5 years, 28.5 ± 6.1 vs. 28.4 ± 4.9 kg/m2, respectively; P>.05 for all). The mean waist circumference (WC) of the HT group was significantly higher than that of the control group (100.6 ± 14.6 vs. 93.2 ± 13.2 cm, P = .015). While FBG, low-density lipoprotein cholesterol (LDL-C), and triglyceride levels in the HT group were significantly higher than in the control group, insulin levels and HOMA-IR were similar. Ghrelin levels were lower in HT patients compared to controls (416.9 ± 224.4 and 689.9 ± 191.6 pg/mL, respectively; P<.001). Ghrelin levels were similar in patients with low and high anti-TPO titers. Negative correlations were observed between ghrelin levels and BMI, WC, and anti-TPO levels. Regression analysis revealed that HT was the most important predictor of ghrelin levels. CONCLUSION: Euthyroid HT is associated with a decrease in plasma ghrelin levels. Altered body fat distribution and increased anti-TPO levels do not seem to be directly involved in lower ghrelin levels in euthyroid HT patients.

RESUMO

OBJECTIVE: We aimed to determine the risk factors of methicillin-resistant Staphylococcus aureus (MRSA) colonization, and the impact of colonization on MRSA infection to evaluate the necessity of MRSA survey program in intensive care units (ICUs) in Turkey. METHODS: The patients hospitalized in medical and neurosurgical ICUs longer than 24 hr were included into the study. To determine anterior nares MRSA colonization, swabs were taken from each patient in the first 48 hr, and followed by once a week till discharge from ICUs. RESULTS: During the one-year follow-up period, the number of the hospitalized patients who spent more than 24 hr in ICUs was 195 of 372 and 85 of 619 in medical and neurosurgical ICUs, respectively. Totally, 23 out of 280 patients (14 from medical ICU, 9 from neurosurgical ICU) were colonized with MRSA, and 11 out of 23 colonized patients were accepted as ICU-acquired infection. The duration of ICU hospitalization in patients with ICU-acquired MRSA colonization was found to be longer than the noncolonized patients (18 days vs. 8 days, P value < 0.001). The presence of gastrostomy and femoral catheter were determined as risk factors for ICU-acquired MRSA colonization. The percentages of MRSA infection in patients with and without MRSA colonized were 8.6% and 1.1%, respectively (P value: 0.009). CONCLUSION: The presence of gastrostomy and femoral catheter, and the duration of ICU hospitalization were found to be related with ICU-acquired MRSA colonization. Also, MRSA nares colonization increased the rates of both MRSA infection and ICU hospitalization.

RESUMO

BACKGROUND AND AIM: The aim of the present study was to assess the efficacy and tolerability of budesonide as an alternative first line treatment option for autoimmune hepatitis (AIH) and the overlap syndrome. METHODS: A total of 18 AIH or overlap syndrome patients were evaluated. Outcomes of treatment by the end of the study were defined as treatment failure, partial response, complete response and remission. RESULTS: Complete response and remission were achieved in 61.1% (11/18) of patients, while 38.9% (7/18) of patients were considered treatment failures. Liver fibrosis was observed in 55.5% of patients' biopsies. More patients with liver fibrosis failed to respond to treatment compared to patients without fibrosis, a difference bordering on statistical significance (60% vs. 12.5%; p=0.066). Although statistically insignificant, the presence of at least one side effect was observed more frequently in patients with fibrosis compared to those without fibrosis (80% vs. 37.5%; p=0.145). Overall, side effects occurred significantly more commonly in non-responders than responders (100% vs. 36%; p=0.013). CONCLUSIONS: Budesonide is an effective treatment option for the management of AIH, with a low incidence of side effects in patients without findings of advanced liver disease. The presence of liver fibrosis may increase the likelihood of treatment failure as well as the risk of developing side effects. Our study findings suggest that budesonide may be effective in a select group of AIH patients. Further studies are needed to determine its exact place for the treatment of AIH and overlap syndrome.

RESUMO

Acremonium spp. are filamentous, cosmopolitan fungi frequently isolated from plant debris and soil, they are known to result in invasive infections in the setting of severe immunosuppression. In this letter, we present a case of catheter-related fungaemia associated with Acremonium spp. in a patient with chronic renal failure. After removal of the subclavian catheter, the patient was treated successfully with voriconazole, with a loading dose of 400 mg followed by a maintenance dose of 200 mg bid. To the best of our knowledge, this is the first paper reporting Acremonium spp. associated fungaemia in a relatively immunocompetent host. We also discuss the diagnosis and treatment of Acremonium spp. associated infections in the context of current literature.

RESUMO

Topical hemostatic agents are applied locally to areas of injured vascular endothelium to control local bleeding. Ankaferd Blood Stopper (ABS) has gained approval in Turkey and Bosnia-Herzegovina as a topical haemostatic agent for external post-surgical and post-dental surgery bleeding. The safety of topical use of ABS has been demonstrated in numerous in vitro and in vivo animal models, as well as in a clinical Phase I trial in humans. ABS, besides its haemostatic activity, also has in vitro anti-infectious and anti-neoplastic effects. To assess potential detrimental effects of intravenous administration of ABS into intact systemic circulation in a rabbit experimental model, one milliliter of ABS was administered intravenously into the systemic circulation of twelve rabbits which were included in the study via the marginal ear vein. Animals were observed for 1 hr before euthanasia was performed by administering 40 mg of intracardiac suxamethonium chloride. In the event of death (cardiopulmonary arrest) before the end of the planned observation period of 60 minutes, time of death was recorded and histopathological examination of the liver and spleen was commenced. Ten rabbits were alive by the end of the planned observation period, without showing any clear signs of discomfort, whereas two animals died within five minutes after systemic administration of intravenous ABS. Postmortem histopathological examination of the livers and spleens of all animals' revealed findings consistent with hepatic venous outflow obstruction. Systemic intravascular administration of ABS into intact vascular endothelium should never be performed in any setting. Further experimental and clinical studies on this liquid hemostatic agent should proceed by accepting ABS as purely a topical haemostatic agent, to be applied solely to areas of injured vascular endothelium.

RESUMO

Budd-Chiari syndrome is a spectrum of manifestations which develops as a result of hepatic venous outflow obstruction. Transjugular intrahepatic portosystemic shunt (TIPS) is a minimally invasive vascular and interventional radiological procedure indicated in the management of refractory ascites in such patients. Conventional TIPS requires the presence of a patent hepatic vein and reasonable accessibility to the portal vein, and in patients with totally occluded hepatic veins, this procedure is technically challenging. Direct intrahepatic portosystemic shunt (DIPS) or so called "percutaneous TIPS" involves ultrasound-guided percutaneous simultaneous puncture of the portal vein and inferior vena cava followed by introduction of a guidewire through the portal vein into the inferior vena cava, as a deviation from conventional TIPS. Described here is our experience with DIPS. Three patients with BCS who had refractory ascites but were unsuitable for conventional TIPS due to occlusion of the hepatic veins were chosen to undergo the DIPS procedure. Our technical success was 100%. The shunts placed in two patients remain patent to date, while the shunt in a third patient with underlying antiphospholipid syndrome was occluded a month after the procedure. The percutaneous TIPS procedure seems to be technically feasible and effective in the management of refractory ascites as a result of BCS, particularly in the setting of occluded hepatic veins.

RESUMO

We report two patients with acute hyponatremic encephalopathy which developed after massive water ingestion for pelvic ultrasound and emphasize the findings of magnetic resonance (MR) imaging including diffusion-weighted imaging (DWI). Both subjects had completely recovered within 24 hours following fluid restriction and salt replacement. MR imaging revealed cortical sulcal narrowing, restricted diffusion and sulcal T2 hyperintensity along with diffuse pial enhancement suggesting diffuse cerebral cortical cytotoxic edema and blood-brain barrier breakdown. In addition to the first illustration of multimodality MR imaging features of water-intoxication, these two cases also highlight the need for standardized practice on the quantity of water intake recommended to distend the bladder for pelvic ultrasound, especially in patients at risk for serum inappropriate ADH syndrome-related hyponatremia.

RESUMO

Congenital hepatic fibrosis (CHF) is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. It is one of the fibropolycystic diseases, which also include Caroli disease, autosomal dominant polycystic kidney disease, and autosomal recessive polycystic kidney disease. Clinically it is characterized by hepatic fibrosis, portal hypertension, and renal cystic disease. CHF is known to occur in association with a range of both inherited and non-inherited disorders, with multiorgan involvement, as a result of ductal plate malformation. Because of the similarities in the clinical picture, it is necessary to differentiate CHF from idiopathic portal hypertension and early liver cirrhosis, for which a liver biopsy is essential. Radiological tests are important for recognizing involvement of other organ systems. With regards to our experience at Hacettepe University, a total of 26 patients have been diagnosed and followed-up between 1974 and 2009 with a diagnosis of CHF. Presentation with Caroli syndrome was the most common diagnosis, with all such patients presenting with symptoms of recurrent cholangitis and symptoms related to portal hypertension. Although portal fibrosis is known to contribute to the ensuing portal hypertension, it is our belief that portal vein cavernous transformation also plays an important role in its pathogenesis. In all patients with CHF portal vein morphology should be evaluated by all means since portal vein involvement results in more severe and complicated portal hypertension. Other associations include the Joubert and Bardet-Biedl syndromes.
