Clinical guidelines typically endorse conventional therapies such as 5-aminosalicylic acid (5-ASA) as the mainstay of ulcerative colitis management. However, the degree of adoption and application of guideline recommendations by physicians within Asia remains unclear. This study aims to understand the prescribing patterns of 5-ASA and implementation of current guideline recommendations across Asian clinical practice. A physician survey was conducted among inflammatory bowel disease specialists in 8 Asian territories to understand practices and preferences in ulcerative colitis management, focusing on the use of 5-ASA and concordance with guideline recommendations. Survey findings were validated by country experts in diverse healthcare settings. Subgroup analyses stratified data by income levels and treatment reimbursement status. Ninety-eight valid responses were received from inflammatory bowel disease specialists or gastroenterologists among 8 economic entities. Significant differences were found in clinical practices and treatment preferences for ulcerative colitis management among different income-level and government-subsidy groups. Survey results are summarized in 8 findings that illustrate trends in 5-ASA use and guideline implementation across Asian territories. This study emphasizes socioeconomic factors that impact the adoption of guideline recommendations in real-world practice. Our findings indicate an eclectic approach to guideline implementation across Asia, based on resource availability and feasibility of treatment goals.

Background and Objectives: This study aimed to evaluate Mal de Debarquement syndrome (MdDS) in high-risk pilots using the Istanbul MdDS Symptom Questionnaire (IMdDSSQ) and investigate the effect of flight time. Subjects and Methods: The IMdDSSQ was administered to 150 healthy pilots, ≥18 years (37.47±11.14 years), on active duty, using a Google Forms link. The responses to the questionnaire were assessed based on flight time (<4 h and >4 h) and age group, for all subfactors. Results: For the MdDS diagnosis subfactor of the questionnaire, 32.1% of males and 66.7% of females reported a suspicion of MdDS after flights <4 h. As flight time increased, the number of participants reporting suspected MdDS increased in both sexes. There was a significant difference between short and long flights for all subfactors of the questionnaire across all age groups and sex comparisons (p<0.05). Conclusions As flight time and age increased, the severity of the symptoms of MdDS increased for all subfactors. With advancing age, dizziness and the severity of intolerance to visual motion increase in long flights compared to short flights, and the quality-of-life decreases. The quality-of-life of female pilots was lower than that of male pilots.

Background and Objectives: Virtual reality (VR) applications change the perception of reality, resulting in a feeling of being in a natural environment. The occurrence of cybersickness (CS) when using VR applications is a well-documented side effect, and the Simulator Sickness Questionnaire (SSQ) has been used to assess CS. Considering the speed of VR technology development, CS will likely become a frequently researched and discussed topics in the near future. Therefore, the aim of this study was to conduct a Turkish validity and reliability study and introduce the SSQ to Turkish medical literature. Materials and Methods: A total of 160 healthy individuals (80 females and 80 males) aged >18 years (28.4±7.2 years) were included in our study. The SSQ was provided to the participants through Google Forms before and after the VR provocation experience and within the scope of the test and retest protocol. Results: The reliability and internal consistency of the questionnaire were observed at a high level (Cronbach’s alpha=0.854, Spearman-Brown coefficient r=0.871). Factor analysis was performed and the questionnaire was divided into three subfactors, consistent with the original questionnaire. In the responses obtained from the participants before and after VR provocation, statistically significant differences were observed in 13 of the 16 items in the questionnaire that are related to VR provocation (p<0.05). Statistically, the differences in fatigue, dizziness, and vertigo were greater in females than in males (p<0.05). Conclusions The Turkish version of the SSQ is an effective tool for measuring the side effects in VR environments. The inclusion of the SSQ in the Turkish literature enables the inclusion of non-English-speaking participants in research, especially for disciplines that consider peripheral and central vestibular disorders.

Background: Advancements in surgery, chemotherapy, and radiotherapy have improved survivalfor brain tumor patients, increasing the risk of second primary tumors (SPTs) among long-term survivors. This study examines the types and risks of SPTs in brain tumor patients presenting at a tertiary care hospital. Methods: This single-center, retrospective study explored occurrences of SPTs following prima-ry brain tumors and occurrences of brain tumors as SPTs following primary extra neural tumors. A total of 41 patients were included and analyzed presenting with histologically confirmed SPTs between 1st January 2000 and 31st December 2020. Results: The study included 41 patients with SPTs, primarily female (65.9%). Of these, 20 pa-tients (48.7%) developed SPTs after a primary brain tumor, while 21 patients (51.2%) developed brain tumors as SPTs after extra-neural tumors. Among patients who developed SPTs after brain tumors (n=20), meningioma (n=8, 40.0%) and pituitary adenoma (n=6, 30.0%) were the most prevalent first primary tumors (FPTs) while breast tumors predominated as SPTs (n=4, 20.0%). Survival analysis indicated younger mean age (44.5 years) for patients marked alive, compared to those marked deceased (57.0 years) and those with unknown outcomes (63.0 years). Conclusion Based on this retrospective analysis, the median age at diagnosis was 44.5 years,with a considerable number of patients (36.6%) having uncertain outcomes at follow-up due to incomplete records. These findings highlight the need for improved follow-up data management to better assess long-term survival in patients with SPTs following brain tumors.

Breast cancer is one of the most common causes of death all over the world. Therapeutic options applied to the patients include surgery, chemotherapy, and radiotherapy.However, far advanced disease often leads to chemoresistance and toxicity. Innovative therapies are needed to address these challenges. Melatonin has the potential to prevent and treat cancer, as it has been revealed in numerous clinical studies. Melatonin is a nontoxic agent that is mostly produced in the pineal gland, inducing various mechanisms of action such as the induction of apoptosis, antiangiogenic, antiproliferative, and metastasis-inhibitory effects. Therefore, melatonin increases therapeutic sensitivity when combined with conventional medication in breast cancer. Melatonin (3-20 mg/day) may reduce breast cancer cell growth in preclinical studies and enhance chemotherapy efficacy. Small human trials suggest potential benefits, but larger studies are needed. Higher doses (≥20 mg/day) are sometimes used alongside chemotherapy. This manuscript reviews research that has demonstrated the antitumor properties of melatonin, thereby focusing on its actions on angiogenesis, apoptosis, metastasis, and antiproliferative properties. We also discuss recent advances in the understanding of the actions of melatonin on epigenetic mechanisms (especially DNA methylation) and telomere length. The data in this review were obtained from journal articles up to May 2024.Regarding the study, Google Scholar and ScienceDirect were used as engines to search for open access. We searched the ISI, Pubmed and Scopus as valid external databases, and as internal databases, ISC and Iran medex. By finding mean keywords such as ‘breast cancer’, ‘estrogen’, ‘melatonin’, ‘cell death’, ‘cell proliferation’, ‘telomerase’ and ‘DNA methylation’, we reached to the formula with maximum collectivity in searching, then equivalent terms were found by Mesh database. The review also covers recent clinical investigations of melatonin in breast cancer.

Background/Aims: The irregular Z-line, defined as a segment of columnar mucosa less than 1 cm in the distal esophagus, is often biopsied despite guidelines advising against it due to a low risk of progression to esophageal adenocarcinoma (EAC). However, the clinical significance of an irregular Z-line remains unclear. This meta-analysis examines the prevalence of Barrett’s esophagus, dysplasia, and EAC in patients with an irregular Z-line. Methods: We searched Medline, Embase, and Scopus databases up to October 2023 for studies on the prevalence of Barrett’s esophagus, dysplasia, and EAC in these patients. A random-effects model was used for meta-analysis, and heterogeneity was assessed using I2 statistics. Results: Nine studies involving 17,637 patients were analyzed. Among those with an irregular Z-line, the prevalence of intestinal metaplasia was 29.4%. In patients with intestinal metaplasia, dysplasia was found in 6.2%, low-grade dysplasia in 5.9%, high-grade dysplasia in 1.6%, and EAC in 1.5%. These rates were higher compared to those without intestinal metaplasia. Conclusions Patients with an irregular Z-line and intestinal metaplasia may be at higher risk and could benefit from endoscopic surveillance. Further studies are needed to determine the necessity of biopsying irregular Z-lines.

Purpose: We evaluated the effectiveness of early start of long-acting insulin during management of diabetic ketoacidosis (DKA) in pediatric patients. Methods: Patients with DKA were randomly assigned to receive either a traditional DKA management protocol or concurrent administration of subcutaneous (SC) long-acting insulin alongside intravenous insulin during DKA treatment. The primary outcomes were duration of insulin infusion and adverse effects of the intervention, mainly hypoglycemia and hypokalemia. Results: For this study, 100 pediatric patients with DKA were enrolled, 50 in each group (group I received the conventional DKA management and group II received conventional DKA management plus SC long-acting insulin once daily). Patients in group II showed a significant reduction in both duration and dose of insulin infusion compared to group I, with a median (interquartile range) of 68.5 hours (45.00–88.25 hours) versus 72 hours (70.25–95.5 hours) (P=0.0001) and an insulin dose of 3.48±1.00 units/kg versus 4.04±1.17 units/kg (P=0.016), respectively. Concurrent administration of SC long-acting insulin with intravenous insulin during DKA treatment was associated with a decreased risk of hypoglycemia (number of hypoglycemia events: group I, 22 events; group II, 12 events, P=0.029), with no increased risk of hypokalemia compared to the control group (number of hypokalemia events: group I, 12 events; group II, 19 events, P=0.147). Conclusion The current study showed that coadministration of SC long-acting insulin in addition to the usual insulin infusion during DKA management in the pediatric population can lead to a shorter duration of insulin infusion. In addition, this approach is not associated with increased risk of hypoglycemia or hypokalemia. Moreover, coadministration of long-acting insulin may be associated with a decreased incidence of hypoglycemia.

Type 2 diabetes mellitus (T2DM) management demands innovative strategies that address its complex nature. Telerehabilitation and conventional rehabilitation, which utilize wearable devices, represent promising avenues in this regard. This narrative review synthesizes the current literature to comprehensively compare these modalities in terms of accessibility, monitoring mechanisms, patient adherence, cost-effectiveness, and social support. Telerehabilitation offers unparalleled convenience, real-time monitoring, and personalized feedback through wearables, thereby fostering greater patient engagement and adherence compared to conventional rehabilitation. However, conventional rehabilitation provides face-to-face interactions, immediate feedback, and a more personalized touch, albeit with logistical challenges and higher costs. This review emphasizes the significance of patient preferences, technological access, and healthcare infrastructure in selecting the appropriate approach. It also calls for further research into long-term outcomes, cost-effectiveness, and the optimal integration of wearable technology in diabetes management programs. Ultimately, both telerehabilitation and conventional rehabilitation demonstrate considerable potential in empowering individuals with T2DM, underlining the imperative for tailored and patient-centric interventions in diabetes care. The review also stresses the significance of integrating patient preferences and their level of comfort with technology when deciding on treatment approaches. It also takes into account the diverse socioeconomic contexts and healthcare infrastructures globally, which can affect the viability and efficacy of both telerehabilitation and conventional rehabilitation. Moreover, the integration of wearable technology in diabetes management programs holds promise for enhancing self-management capabilities and promoting healthier lifestyles. However, it is essential to tackle prospective discrepancies in access to these technologies and ensure fair distribution. Looking forward, ongoing research efforts should focus on justifying long-term outcomes, optimizing cost-effectiveness, and refining implementation strategies to maximize the benefits of both modalities.
