RESUMEN
Background and Aim: Adequate bowel preparation is necessary for optimal colonoscopy. Inadequate bowel preparation results in increased costs and imprecise colonoscopy results. This study aims to determine the incidence and risk factors of inadequate bowel preparation. Methods: In this study, 604 consecutive patients were observed prospectively who underwent colonoscopy examination. The patient's clinical and demographic data were obtained on the day of the procedure. Bowel preparation was evaluated by Boston Bowel Preparation Scale (BBPS) and was divided into two groups; adequate and inadequate. Univariate and multivariate analyses were performed. Results: Inadequate bowel preparation incidence was 17.9%. In the univariate analysis, education level (P value = 0.009), body mass index (P value = 0.03), admission type (P value = 0.038), previous history of colonoscopy (P value = 0.03), color and consistency of the last feces (P value = 0.03), diabetes (P value = 0.004), and smoking (P value = 0.03) were significantly related with the incidence of inadequate bowel preparation. While ischemic heart disease (IHD) decreased the level of inadequate bowel preparation (P value = 0.047). Multivariate analysis showed that diabetes mellitus (odds ratio [OR] = 2.18), smoking (OR = 2.10), inpatient status of admission type (OR = 3.32), last stool that was non-watery (OR = 1.60), and ischemic heart disease (OR = 0.032) were independent factors associated with inadequate bowel preparation. Conclusion: Diabetic patients, smokers, inpatients and who defecated a non-watery and colory stool as the last defecation are at risk of inadequate bowel preparation and need more potent regimens. It is important to inform patients about preventable factors that affect bowel preparation to improve their preparation outcomes.
RESUMEN
BACKGROUND: Considering the role of adipokine on diseases related to metabolic syndrome and even chronic diseases, it seems necessary to investigate effective interventions on these factors. This study aimed to comprehensively investigate the effects of metformin on adipokines. METHODS: A comprehensive search was conducted in five databases using established keywords. The purpose of this search was to uncover controlled studies that have examined the impact of metformin on adipokines, specifically leptin, adiponectin, and resistin. The random-effects model analysis was used to provide pooled weighted mean difference and 95% confidence intervals. RESULTS: Forty-nine studies were included in this article. The pooled findings showed that that the administration of metformin significantly decreases leptin (WMD: -3.06 ng/ml, 95 % CI: -3.81, -2.30, P < 0.001) and resistin (WMD: -1.27 µg/mL, 95 % CI: -2.22, -0.31, P = 0.009) levels in different populations compared to the control group. However, no significant effect of this antidiabetic drug on adiponectin levels was reported. The results obtained from the subgroup results in the present study also showed that metformin in people with a BMI greater than 30 kg/m2 compared to a BMI ≤ 30 kg/m2 causes a significant decrease in leptin levels and an increase in adiponectin levels. Also, metformin in lower doses (≤1500 mg/day) and younger people (<30 years) causes a significant increase in adiponectin levels. CONCLUSIONS: In general, considering the role of adipokines on metabolic disease and even chronic disease, this drug can be used as a potentially useful drug, especially in obese people, to improve these factors.

Purpose: This study aims to investigate comorbidities, clinical features, laboratory values, and diagnoses in non-diabetic patients experiencing hypoglycemic episodes. Methods: A retrospective observational study was conducted at Shariati Hospital in Iran from 2016 to 2023. Seventy-four non-diabetic patients admitted with a diagnosis of hypoglycemia were included, while patients with diabetes were excluded. Demographic data, symptoms, and biochemical assessments were obtained from the hospital information system. Hypoglycemic episodes were identified based on low measured blood glucose, recorded medications for hypoglycemia treatment, or recorded codes indicating hypoglycemia. Hypoglycemia was defined as blood glucose below 70 mg/dL (3.9 mmol/L) along with two other criteria of the Whipple triad. Statistical analysis was performed using SPSS software (version 26). Results: Among the enrolled patients, 63.5% were female, and 13.5% were elderly (≥ 65 years). The most common comorbidities observed were cardiovascular disease (20.3%), psychological disorders (20.3%), hypothyroidism (14.9%), and hypertension (8.1%). The prevalent symptoms included weakness, loss of consciousness, sweating, palpitations, dizziness, and tremors. Non-diabetic hypoglycemia was caused by factitious disorders, insulinoma, organ failure, and infection, respectively. Conclusion: Due to the diverse range of clinical symptoms, hypoglycemia in non-diabetic patients may be diagnosed late, leading to misdiagnoses such as psychological disorders or seizures. It is crucial to consider the possibility of hypoglycemia in non-diabetic patients and determine its underlying cause. Given the poor prognosis associated with hypoglycemia, timely interventions are essential.
RESUMEN
Purpose: Thyroid cancer is recognized as the predominant form of endocrine cancer. The likelihood of cancer recurrence and the development of distant metastases varies depending on the cancer's pathology and stage. Iran currently lacks country-specific data on thyroid cancer, which can potentially result in clinicians deviating from the optimal treatment. The primary objectives of establishing such a registry are to determine the incidence, identify risk factors, and evaluate treatment outcomes for thyroid cancer within the Iranian population. Ultimately, the overarching goal of this protocol study is to reduce mortality and morbidity rates among thyroid cancer patients by implementing appropriate interventions based on the findings derived from this registration system. Methods: The study will enroll all individuals aged 18 years and older who have received a diagnosis of primary thyroid carcinoma based on pathology criteria. Data will be collected from various thyroid clinic centers. The participating centers include the Endocrinology Clinic at Shariati Hospital, the Thyroid Clinic in the Nuclear Medicine Center at Shariati Hospital, as well as pathology and nuclear medicine centers in Kerman and Bushehr. Patient records comprise information on outpatient visits to the clinic. Conclusion: The registry aims to enhance treatment approaches and follow-up protocols while serving as a foundation for conducting clinical, epidemiological, and basic science studies based on robust evidence-based data.
