Assessment of psychological terror and its impact on mental health and quality of life in medical residents at a reference medical center in Mexico: A cross-sectional study.

BACKGROUND: Mobbing, particularly in medical residencies, can lead to psychological terror with lasting mental and physical health consequences. Its impact on Mexican residents, however, remains underexplored. AIM: This study aimed to investigate the prevalence and associated factors of psychological terror among medical residents at a medical center in Mexico City. METHODS: In a cross-sectional study, medical residents from various specialties were assessed for mobbing domains, quality of life, and anxiety/depression using the Leymann Inventory of Psychological Terror (LIPT), 36-Item Short Form Health Survey, Beck Depression Inventory-II, and Beck Anxiety Inventory, respectively. Psychological terror was defined as a LIPT score ≥ p80. Linear and binomial logistic regression models were used to explore independent predictors of mobbing and psychological terror. RESULTS: Of the 349 participants included (median age: 28; IQR: 27-30 years), 19.5% (95% CI: 15.5%-24.0%) were identified with psychological terror. Furthermore, 39% reported higher-degree trainees as mobbing perpetrators. Women in surgical residencies in their second or fifth year were found to experience higher levels of mobbing. Manifested bullying, workplace stigma, and inappropriate tasks were the most impacted mobbing domains. Anxiety, diminished mental health quality of life, and higher degree of medical specialization were independent predictors of mobbing. Meanwhile, increased anxiety, affiliation to surgical specialties, and being in the second or fifth year of training were identified as predictors of psychological terror. CONCLUSIONS: Mobbing and psychological terror are prevalent conditions among medical residents in Mexico. Identification of occupational conditions and adverse psychological stressors can help to improve quality of life and training of medical residents.

Diabetes, Active Disease, and Afternoon Serum Cortisol Levels Predict Cushing's Disease Mortality: A Cohort Study.

CONTEXT: Cushing's disease (CD) is a life-threating disease, with increased mortality in comparison with the general population. OBJECTIVE: This study aimed to evaluate standardized mortality ratios (SMRs) in CD patients. We also analyzed independent risk factors related to increased mortality. DESIGN: We conducted a longitudinal cohort study in a 3rd level specialty center, from 1979 to 2018, in patients with CD. RESULTS: From 1375 cases with a pathology diagnosis of pituitary adenoma, 191 cases had the confirmed diagnosis of CD (14%). A total of 172 patients completed follow-up, with a mean age at diagnosis of 33 ±â€…11 years, female predominance (n = 154, 89.5%), majority of them with microadenoma (n = 136, 79%), and a median follow-up of 7.5 years (2.4-15). Eighteen patients (10.5%) died, 8 of them (44%) were with active CD, 8 (44%) were under remission, and 2 (11%) were under disease control. Estimated all-cause SMR = 3.1, 95% confidence interval (CI) 1.9-4.8, P < 0.001. Cardiovascular disease was the main cause of death (SMR = 4.2, 1.5-9.3, P = 0.01). Multivariate Cox regression models adjusted for potential cofounders showed that diabetes (HR = 5.2, IC 95% 1.8-15.4, P = 0.002), high cortisol levels after 1600 hours at diagnosis (3.4, 2.3-7.0, P = 0.02), and active CD (7.5, 3.8-17.3, P = 0.003) significantly increased the risk of mortality. CONCLUSIONS: Main cause of CD mortality was cardiovascular disease. Main risk factors for mortality were uncontrolled diabetes, persistently high cortisol levels after 1600 hours at diagnosis, and active disease at last follow-up.

Quality of life is significantly impaired in both secretory and non-functioning pituitary adenomas.

OBJECTIVE: To evaluate the quality of life (QoL) in patients with pituitary adenomas in comparison with healthy Mexican population QoL scores. DESIGN & MEASUREMENTS: Cross-sectional study using the short form 36 questionnaire (SF-36) in 175 patients with pituitary adenomas grouped by adenoma subtype and disease activity, and compared them with the healthy Mexican population normative QoL scores. PATIENTS: A total of 44 patients with non-functioning pituitary adenomas (NFPA), 48 with acromegaly, 53 with prolactinomas and 30 with Cushing disease (CD) were enrolled in this study. RESULTS: Mental and physical components scores (MCS & PCS) of SF-36 questionnaire were lower in patients with active disease in all adenoma subtypes (P < 0.03). A significant negative relationship between prolactin levels and MCS (r = -0.30, P < 0.01) and PCS (r = -0.41, P < 0.01) were found in prolactinomas. Patients with CD showed 24 hours urine-free cortisol levels negatively correlated with MCS (r = -0.43, P < 0.01) but not with PCS. No significant correlation was found between IGF-1 ULN and QoL scores in acromegaly. NFPA patients had lower QoL scores than patients with controlled CD, acromegaly or prolactinoma (P < 0.02). Active CD and prolactinoma have lower QoL scores in comparison of NFPA (P < 0.05). Having an adenoma, secretory or non-functioning, decrease QoL scores in comparison of results in the healthy Mexican population register. Using an adjusted-multivariate model, we confirmed that disease activity in all secretory adenomas is an independent risk factor, reducing SF-36 scores significantly. CONCLUSION: Activity in all secretory pituitary adenomas' patients decrease mental and physical QoL. However, independently of disease activity, secretory and NFPA significantly decrease QoL in comparison with healthy Mexican population QoL register.

A Higher Fructose Intake Is Associated with Greater Albuminuria in Subjects with Type 2 Diabetes Mellitus.

The aim of this single center cross-sectional study was to investigate the association between fructose intake and albuminuria in subjects with type 2 diabetes mellitus (T2DM). This is a single center cross-sectional study. One hundred and forty-three subjects with T2DM were recruited from the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran. The median daily fructose intake was estimated with a prospective food registry during 3 days (2 week-days and one weekend day) and they were divided into low fructose intake (<25 g/day) and high fructose intake (≥ 25 g/day). Complete clinical and biochemical evaluations were performed, including anthropometric variables and a 24-hour urine collection for albuminuria determination. One hundred and thirty-six subjects were analyzed in this study. We found a positive significant association between daily fructose intake and albuminuria (ρ= 0.178, p=0.038) in subjects with type 2 diabetes mellitus. Other variables significantly associated with albuminuria were body mass index (BMI) (ρ= 0.170, p=0.048), mean arterial pressure (MAP) (ρ= 0.280, p=0.001), glycated hemoglobin (A1c) (ρ= 0.197, p=0.022), and triglycerides (ρ= 0.219, p=0.010). After adjustment for confounding variables we found a significant and independent association between fructose intake and albuminuria (ß= 13.96, p=0.006). We found a statistically significant higher albuminuria (60.8 [12.8-228.5] versus 232.2 [27.2-1273.0] mg/day, p 0.002), glycated hemoglobin (8.6±1.61 versus 9.6±2.1 %), p= 0.003, and uric acid (6.27±1.8 versus 7.2±1.5 mg/dL), p=0.012, in the group of high fructose intake versus the group with low fructose intake, and a statistically significant lower creatinine clearance (76.5±30.98 mL/min versus 94.9±36.8, p=0.014) in the group with high fructose intake versus the group with low fructose intake. In summary we found that a higher fructose intake is associated with greater albuminuria in subjects with T2DM.

Fibroblast growth factor 21 and its novel association with oxidative stress.

Fibroblast growth factor 21 (FGF21) is an endocrine-member of the FGF family. It is synthesized mainly in the liver, but it is also expressed in adipose tissue, skeletal muscle, and many other organs. It has a key role in glucose and lipid metabolism, as well as in energy balance. FGF21 concentration in plasma is increased in patients with obesity, insulin resistance, and metabolic syndrome. Recent findings suggest that such increment protects tissue from an increased oxidative stress environment. Different types of physical stress, such as strenuous exercising, lactation, diabetic nephropathy, cardiovascular disease, and critical illnesses, also increase FGF21 circulating concentration. FGF21 is now considered a stress-responsive hormone in humans. The discovery of an essential response element in the FGF21 gene, for the activating transcription factor 4 (ATF4), involved in the regulation of oxidative stress, and its relation with genes such as NRF2, TBP-2, UCP3, SOD2, ERK, and p38, places FGF21 as a key regulator of the oxidative stress cell response. Its role in chronic diseases and its involvement in the treatment and follow-up of these diseases has been recently the target of new studies. The diminished oxidative stress through FGF21 pathways observed with anti-diabetic therapy is another clue of the new insights of this hormone.
