Objective. The mechanisms underlying the development of diabetic neuropathic pain (NeP) are still unknown. The aim of the study was to evaluate painful diabetic neuropathy in Type II diabetic patients with Leeds Assessment of Neuropathic Symptoms and Signs Scale (LANSS), thermal and vibratory Quantitative Sensory Testing (QST) and, EMG supported Diabetic Neuropathy Score (DNS) and to evaluate the differences in patients with and without neuropathic pain. Methods. Eighty three Type II diabetic patients (26 males, 57 females) were investigated. Patients with pain were assessed by the LANSS pain scale and a score of ≥12 was classified as NeP. All patients underwent nerve conduction studies (NCS) to obtain EMG supported diabetic neuropathy score (DNS). Cold and warm sensation thresholds and cold pain and heat pain thresholds were obtained for evaluation of A-delta and C type fibers. Vibratory perception thresholds were recorded for evaluation of thickly myelinated fibers. Results. The percentage of NeP (LANSS score ≥12) was 15.7 %. QST revealed significantly lower cold detection, higher warm detection and higher heat pain thresholds at the feet in patients with NeP compared with patients without NeP. Although small fiber dysfunction has been revealed in all patients with NeP, the percentages of the presence of small fiber neuropathy and EMG supported diabetic neuropathy were not significantly different among patients with NeP and without NeP. Conclusions. We concluded that QST is a useful and a noninvasive tool to detect small fiber dysfunction in Type II diabetic patients. QST revealed increased severity of small fiber dysfunction in patients with NeP. Although small fiber neuropathy has been revealed in all Type II diabetic patients with neuropathic pain the absence of pain does not predict preserved small fiber function.

Background. ThyPRO is a recently developed thyroid-specific quality of life (QoL) questionnaire applicable to patients with benign thyroid disorders(BTD). The aim of the present study was to translate ThyPRO and ThyPRO-39 into Romanian, and to evaluate reliability and cross-cultural validity. Methods. Standard methodology for translation and linguistic validation of patient-reported outcomes (PRO) was applied. The questionnaire was completed by 130 patients with benign thyroid diseases seen at Department of Endocrinology in the Emergency County Hospital, Tîrgu Mureș, Romania, between October 2015 and March 2016. Internal reliability of the Romanian version of the ThyPRO (ThyPROro) scales was assessed for multi-item scales using Cronbach’s alpha coefficient. An efficient method for testing cross-cultural validity is analysis of differential item functioning (DIF). Uniform DIF between the Romanian and the original Danish sample was investigated using ordinal logistic regression. The translation process proceeded without difficulties, and any disagreements were revised by one of the developers and the language coordinator. Results. Internal reliability for ThyPRO was satisfactory. Cronbach`s alpha coefficients for the 13 scales ranged from 0.78 to 0.93 for the ThyPROro and 0.78 to 0.87 for the ThyPROro-39. In the 85-item ThyPRO, nine instances of DIF were found. Most were minor, explaining <3% of the variation in scale score, but DIF in positively worded items were larger, with explained variance (R2’s) around 10-15%. Conclusion. The ThyPROro questionnaire is ready for assessment of health-related quality of life in Romanian patients with benign thyroid diseases.

Context. Understanding factors delaying recovery in thyrotoxicosis patients is crucial for optimizing treatment plan. Objective. This study aimed to identify predictive factors for the delayed thyroid function recovery in thyrotoxicosis patients. Design. The study is a retrospective review of medical records of adult thyrotoxicosis patients diagnosed at Kaohsiung Veterans General Hospital, Taiwan, from January 2014 to December 2021. The duration of follow-up for the main outcome was at least 18 months. Subjects and Methods. Patients newly diagnosed with thyrotoxicosis who were age > 18 years old, had a TSH level <0.1 μIU/mL, received CBZ or PTU treatment, and demonstrated a subsequent TSH increase to above 0.4 μIU/ mL, were included. Results. The study included 443 patients. The average time to achieve normalized TSH levels was 6.9 months. Key factors associated with delayed TSH normalization included higher body mass index (BMI) [odds ratio (OR) = 1.06, confidence interval (CI): 1.01–1.12], elevated serum free T4 levels (OR = 1.97; CI, 1.44–2.69), and treatment with propylthiouracil (OR = 2.66; CI, 1.33–5.32). In contrast, factors such as sex, age, season of diagnosis, and comorbidities did not significantly impact the rate of TSH normalization. Conclusion. The study highlights the importance of considering individual patient characteristics, such as BMI and initial free T4 levels, in thyrotoxicosis management. The findings suggest a potential preference for carbimazole over PTU in achieving faster TSH normalization. This research contributes to the understanding of thyrotoxicosis recovery and supports the need for personalized treatment approaches in clinical practice.

Background. The transport of gametes and embryos is facilitated by motile cilia lining the inside of the fallopian tube. Progesterone regulates ciliary beat frequency (CBF) through multiple types of progesterone receptors in the fallopian tube. Membrane progesterone receptors beta and gamma (mPRβ and mPRγ) are both expressed in the ciliated cell lining of the fallopian tubes of humans. This study aimed at exploring the mRNA expression of mPRβ and mPRγ in the fallopian tubes of women with ectopic pregnancy. Materials and Methods. In this Case control study, a quantitative reverse transcriptase polymerase chain reaction was performed to determine the mRNA expression of mPRβ and mPRγ in the fallopian tubes obtained from 12 women with ectopic pregnancies, 12 women with normal pregnancies, and 12 healthy nonpregnant women in the luteal phase of their menstrual cycle. Results. It was indicated that mPRβ and mPRγ were expressed in the fallopian tube of the three groups of participants. However, the expression of mPRβ and mPRγ mRNA in the fallopian tube of women with ectopic pregnancy was not significantly different from that of the nonpregnant and normal pregnant women. Conclusion. These results suggest that mPRs might play no role in etiology of ectopic pregnancies associated with disturbed progesterone signalling.

Obesity is a well-recognized risk factor for type 2 diabetes, cardiovascular disease, and several types of cancer. However, a proportion of the obese individuals display a significantly lower risk for metabolic complications than expected for their degree of body mass index, and this subtype of obesity was described as “metabolically healthy obesity” (MHO). No universally accepted criteria for the diagnosis of MHO exists and the prevalence of this subtype of obesity varies largely according to criteria used. Broadly, MHO is characterized by a lower amount of visceral fat, a more favorable inflammatory profile, and less insulin resistance as compared to the metabolically unhealthy obesity. Currently, controversies exist regarding the risk of cardiovascular events and all-cause mortality associated with MHO as compared to metabolically-healthy non-obese individuals. Further research is needed in order to identify the MHO phenotype and if MHO is truly healthy for a long period of time or if it is a transient state from normal metabolic/normal weight to abnormal metabolic/obese state. This review will discuss the MHO definition criteria; the differences between MHO and metabolically unhealthy obesity; the possible underlying mechanisms and clinical implications of MHO.

Objectives. We aimed to determine lipodystrophy frequency according to insulin treatment regimen and insulin injection frequency in type 2 diabetic patients. Methods. A total of 345 type 2 diabetic patients under insulin treatment for at least one year were included in this cross-sectional study. Patients were examined for presence of lipodystrophy, insulin injection frequency and dosage. Lipodystrophy was evaluated with visual inspection and palpation of all injection sites. Patients were evaluated into three categories according to daily insulin dose requirement: Group 1= Standard-dose insulin users 0.6 U/ kg/day; Group 2= Medium-dose insulin users 0.61-1.9 U/kg/ day, Group 3= High-dose insulin users ≥2 U/kg/day. Results. Lipodystrophy was seen in 28% of the patients. Lipodystrophy was significantly higher in group 3. There was no significant difference between the groups in terms of lipodystrophy size. Duration of insulin treatment, daily total insulin dose, daily insulin dose per weight and number of daily insulin injections were significantly higher in the group with lipodystrophy. Daily injection number of long-acting, rapidly-acting analog and total insulin injections were significantly higher in group 3 than group 1 and 2. Number of daily insulin injections and lipodystrophy frequency were significantly higher in basalbolus insulin user group. Multivariate analysis showed that insulin injection frequency is the independent risk factor for lipodystrophy. Conclusion. Lipodystrophy is still a clinical problem in patients with high-dose insulin requirement and frequent insulin injections. Reducing daily insulin requirement and daily number of injections should be given priority in the management of patients to prevent the development of lipodystrophy.

Objective. Exercise intensity is one of the most important factors that determines the effects of exercise; however, there is little known about the acute glycemic control of different exercise intensities on patients with Type 2 Diabetes Mellitus (T2DM). Here we aimed at exploring the influence of a single bout of exercise with different intensities on blood glucose levels in T2DM patients. Methods. Fifteen subjects (54.7 ± 5.8 years old) participated in a session of walking (WG), jogging (JG), or sedentary control (CG) in a randomized order on three different days. Distances in both WG and JG were set as 2 Km with a speed set as 4~4.5 Km/h for walking and 5~6 Km/h for jogging based on pretrial test. Blood glucose levels at fasting (~6:30am), pre-exercise (~8:30am), post-exercise (~9am), 11am and 4pm were detected. Results. Walking and jogging reached approximately moderate and high intensity based on the immediate post-exercise heart rate and RPE scores. Blood glucose levels at fasting, pre-exercise and 4pm were not substantially different among all groups (p > 0.05). JG had a significantly lower post-exercise blood glucose level (p < 0.05) when compared with CG and WG. The blood glucose level at 11am was notably lower in WG and JG than in CG (p < 0.05). Conclusions. Both a single bout of jogging and walking can lower postprandial blood glucose levels in T2DM patients. When matched for exercise distance, jogging represents a more effective strategy to immediately lower postprandial glucose levels than walking.

Objective. This research aim was to evaluates the role of the pre-ablation neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) as predictors of distant metastases in patients with differentiated thyroid cancer (DTC). Methods. A retrospective analysis was given to 140 patients with DTC who received 131I remnant ablation after surgery. The patients were divided into two groups based on the existence of distant metastasis. Results. The two groups showed no significant difference in age, gender, WBCs, neutrophils, monocytes, eosinophils, basophils and whether the tumor was multifocal. In the univariate analysis, significant differences were found in tumor size (p=0.021), lymphocyte (p=0.012), NLR (p=0.027), and LMR (p=0.007). According to the ROC curves, NLR had an AUC of 0.612 ± 0.097 with a cut-off value of 1.845, sensitivity of 60.0%, and specificity of 66.2% (p=0.027). LMR had an AUC of 0.638 ± 0.095 with a cutoff value of 4.630, sensitivity of 84.6%, and specificity of 35.4% (p=0.007). In the multivariate analysis, larger tumor size (OR=5.246, 95% CI 1.269-10.907, p=0.009) and higher NLR (OR=2.087, 95% CI 0.977-4.459, p=0.034) were statistically significant for distant metastases. Conclusion. This research reveals that pre-ablation NLR and tumor size are significantly statistically correlated with distant metastases in patients with DTC.

Background. The aim of the present study was to systematically review the effects of Realsil (silybin– phospholipid–vitamin E complex) on liver enzymes in patients with NAFLD or NASH. Methods. We searched Web of Science, MEDLINE, Google Scholar, Cochrane Library, Science Direct, ProQuest, Scopus, and 1868 articles were found up to December 2018. Four studies that examined the effect of Realsil intake on liver enzymes among NAFLD or NASH patients were included. Exclusion criteria include: animal studies, studies with the design other than clinical trials, studies on non-adult individuals, studies that assess the effect of vitamin E, silybin, or phospholipid solely, studies that examined the effect of Realsil on other outcomes, or studies with insufficient data. Results. The analysis demonstrated that Realsil intake led to a significant decrease in Gamma-Glutamyl Transpeptidase (GGT) levels (standardized mean difference (SMD) =-0.37; 95% confidence interval (CI]): -0.68 to -0.06). Realsil intake non-significantly decrease alanine transaminase (ALT) levels (SMD=-1.02 U/L; 95% CI: -2.23 to 0.20) and non-significantly increase aspartate aminotransferase (AST) levels (SMD = 0.17 U/L; 95% CI: -0.26–0.61). Conclusion. Realsil intake was associated with a significantly decreased circulating GGT level without any significant effect on AST and ALT levels.

Context. Pituitary adenomas are benign tumors, usually found in men in their 3rd and 5th decades of life, representing 10-15% of all intracranial tumors. The clinical manifestations include important endocrinological disturbances and visual impairment. Objective. This study aimed to determine the most suitable neurosurgical approach regarding the dimensions, extensions and invasiveness of tumor extensions. Design. This was a systematic review of the literature from 2002-2022, focused on clinical outcome, especially endocrinological state according to the surgical approach. Subjects and Methods. We performed an advanced search on Web of Science and PubMed databases on October 10th, 2022. The literature showed 300 studies in the last 20 years, and after we applied the inclusion and exclusion criteria’s, 19 studies were fully read and analyzed. Results. Postoperative complications were reviewed in each surgical approach group, including visual impairment, new endocrinological disturbances, diabetes insipidus and cerebrospinal fluid leakage. Analyze of the endocrinological findings did not determined differences in transcranial groups from transsphenoidal groups. Overall complications were identified in the transcranial cohorts, while cerebrospinal fluid leakage still represent the main problem in transsphenoidal groups. The majority of studies found included extended endoscopic transsphenoidal approach, which shows results of great potential. Conclusions. For the surgical treatment of pituitary adenoma, transsphenoidal procedure with or without extended approaches is preferred, but they’re cases when a craniotomy is mandatory for a feasible gross tumor resection. Combined “above and below” simultaneous procedure or a two-staged intervention is recommended for giant pituitary adenoma, to maximize tumor resection and lower the risk of cerebrospinal fluid leakage.
