The high stability of the color reagent allows long-term storage for at least 1 year. The optimized procedure is especially useful to measure phosphate-containing biomolecule levels and enzyme activities when low values are critical. Cushing's syndrome (CS) is a severe condition that results from chronic exposure to elevated circulating cortisol levels; it is a rare but potentially life-threating condition, especially when not timely diagnosed and treated. Even though the diagnosis can be straightforward in florid cases due to their typical phenotype, milder forms can be missed. Despite the availability of different screening tests, the diagnosis remains challenging as none of the available tools proved to be fully accurate. Due to the ubiquitous effect of cortisol, it is easy understandable that its excess leads to a variety of systemic complications including hypertension, metabolic syndrome, bone damages and neurocognitive impairment. This article discusses clinical presentation of CS with an eye on the most frequent cortisol-related comorbidities and discuss the main pitfalls of first- and second-line tests in endogenous hypercortisolism diagnostic workup. BACKGROUND Some conceptualizations of hypersexuality posit boredom as a possible trigger of hypersexual behavior. AIM This work aims to review published articles addressing the link between boredom and hypersexuality to investigate if this relationship can yet be established based on current empirical data. METHODS This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies, published until September 2019, were retrieved from EBSCO, Scopus, Web of Science, and PubMed. A systematic search was conducted using an exhaustive list of key terms combining "boredom" with "hypersexuality," "sexual impulsivity," "sexual compulsivity," and "sexual addiction." Only articles presenting empirical results concerning the relationship between boredom and hypersexuality were considered. RESULTS From the initial poll of 76 articles, only 19 articles were included in our final selection. Of the total studies, 16 were quantitative studies and 3 were qualitative studiethis review correspond to anecdotal evidences of the phenomenon, as only few studies used appropriate measures of boredom. CONCLUSION Although current literature identifies a link between boredom and hypersexuality, further substantive research is still much needed to clarify the associations between the 2 constructs. de Oliveira L, Carvalho J.

BACKGROUND AND PURPOSE Embolic stroke of undetermined source (ESUS) is an important contributor to stroke worldwide. Little is known about ESUS in developing parts of the world such as South Asia, West Asia and North Africa despite the high stroke burden in these areas. The purpose of the study was to characterize the prevalence, demographic, risk factor and clinical aspects of ESUS in patients from South Asia, West Asia and North Africa residing in Qatar. METHODS Data were retrospectively collected on 3103 stoke patients. Risk factors and clinical features of the ESUS group were compared to all other strokes using Chi-square or student's t-tests. Logistic regression was used to identify factors associated with ESUS. ESUS patients were compared based on ethnicity using Chi-square or one-way ANOVA. RESULTS 634 patients (30·9%, 95% CI (28·9%-32·9%) met the ESUS criteria. Mean age was 56·3 years ± 13·7 and South Asian ESUS patients were younger than West Asians or North Africans (67·1 ± 13·5 versus 52·1 ± 10·8 versus 53·5 ± 14·2, P = .001). Smoking, diastolic function, prior antiplatelets and wall motion abnormalities were more common in ESUS. Logistic regression showed that South Asian ethnicity (OR 1·50, CI 1·14-1·97, P = ·003), diastolic dysfunction (OR 1·47, CI 1·23-1·75, P = ·005), global (OR 1·79, CI 1·41-2·26, P = ·001) and focal (OR 5·48, CI 3·79-7·92, P = ·001) wall motion abnormalities, predicted ESUS. CONCLUSIONS ESUS is a major cause of stroke in patients from West Asia, South Asia and North Africa residing in Qatar. The clinical profile and risk factors for ESUS vary based on ethnicity. In South Asians, ESUS occurs at a younger age and is most likely cardiogenic in origin. BACKGROUND Tumor-infiltrating lymphocytes (TILs), tumor budding, and micropapillary architecture may influence tumor growth and metastatic potential, thereby enhancing prognostic stratification. We analyzed these features and their relative contribution to overall outcome and in low (T1-3 N1) and high (T4 and/or N2) risk groups that are used to inform the duration of adjuvant chemotherapy in patients with resected stage III colon cancers. PATIENTS AND METHODS Among 1532 patients treated in a phase III adjuvant trial of FOLFOX-based therapy, intraepithelial TIL densities, tumor budding, and micropapillary features were analyzed and quantified in routine histopathological sections with light microscopy. Optimal cut-points were determined in association with disease-free survival (DFS) in training and validation sets. Associations or relative contributions of individual features or combined variables with DFS were determined using multivariable Cox regression models. RESULTS TILs, tumor budding, and micropapillaDENTIFIER NCT00079274. Cisplatin-based neoadjuvant chemotherapy (NAC) has demonstrated an overall survival (OS) benefit in muscle-invasive bladder cancer (MIBC). However, only a subset of patients (25-50%) have a pathologic complete response at cystectomy. Using a cohort of 58 patients from two phase 2 trials, our group previously reported that mutations in the ATM, RB1, and FANCC genes correlate with complete response to cisplatin-based NAC, and consequently improve OS and disease-specific survival (DSS). These trials enrolled patients with T2-4 (N0 or N1) MIBC and treated them with accelerated/dose-dense NAC with methotrexate, vinblastine, adriamycin, and cisplatin, or gemcitabine and cisplatin, with a plan for curative cystectomy. Updated long-term follow-up (median 74 mo) shows that significantly greater OS and DSS was maintained for patients with ATM, RB1, or FANCC mutations. The 5-yr survival rate for patients with at least one mutation was 85%, compared to 45% for patients without a mutation. On the basis of the associations with response and long-term OS and DSS, we propose that these alterations may be useful as predictive biomarkers to allow clinicians to prioritize patients who are most likely to benefit from NAC before radical cystectomy. PATIENT SUMMARY In this report we looked at outcomes for patients with muscle-invasive bladder cancer treated with cisplatin-based chemotherapy before surgery (neoadjuvant) who had mutations in a set of DNA damage repair genes (ATM, RB1, FANCC) compared to those who did not. We found that patients who had at least one mutation in one of these genes survived longer after receiving cisplatin chemotherapy before surgery than patients who did not. INTRODUCTION Isolated subtalar osteoarthritis (OA) is a debilitating condition usually occurring after trauma and particularly in the setting of an intraarticular calcaneal fracture. Currently, subtalar (talo-calcaneal joint) fusion surgery is the treatment of choice in managing subtalar OA after failure of conservative treatment. Unfortunately, subtalar fusion eliminates joint motion and increases the load over the adjacent midfoot and ankle joints, which affects the outcome of the surgery over time. Popular in the ankle, distraction arthroplasty offers another joint-preserving option, particularly important for active patients. In contrast to fusion as a salvage procedure, subtalar distraction arthroplasty allows the possibility of maintaining the function of the arthritic subtalar joint while reducing pain and improving the overall function of the foot and ankle. METHODS We performed subtalar distraction arthroplasty using a circular external fixator combined with BMAC on seven patients with symptomatic anr OA. Furthermore, this new operation does not eliminate the possibility of a future surgery like fusion. read more Subtalar distraction arthroplasty can be helpful in the management of subtalar OA in active patients who desire preservation of foot and ankle motion. Nasoalveolar molding (NAM) is a powerful tool in the treatment of patients with unilateral or bilateral cleft lip and palate. The primary goal of NAM is to improve alignment of critical anatomic elements before surgical repair of the unilateral or bilateral cleft lip. Modifications of the position of the alveolar segments and their associated lip elements, the lower lateral cartilages, and the columella achieved with NAM are helpful for creating a suitable platform for tension-free lip repair. Mesenchymal stromal injection is a promising therapy for traumatic brain injury (TBI). The aim of this study was to explore the effects of the HIF-1α/SDF-1/CXCR4 axis on neuron repair in TBI rats through improving the bone marrow-derived mesenchymalstromal cells (BMSCs) migration. TBI rat models were established. The rats were treated with exogenous SDF-1, and then the neuronal apoptosis in TBI rats was measured. BMSCs from rats were collected, and the roles of NF-κB p65 expression in nuclei, overexpression of SDF-1 and HIF-1α, as well as downregulation of CXCR4 in BMSC migration were identified. HIF-1α- and SDF-1- treated BMSCs were transplanted into TBI rats, after which the neuronal apoptosis and activity of the HIF-1α/SDF-1/CXCR4 axis were detected. Consequently, we found SDF-1 elevated the HIF-1α/SDF-1/CXCR4 activity and presented protective roles in TBI rat hippocampal neurons with reduced neuronal apoptosis. SDF-1 promoted BMSC migration in vitro, and co-effects of SDF-1 and HIF-1α showed strong promotion, while CXCR4 inhibition suppressed BMSC migration. BMSC transplantation activated the HIF-1α/SDF-1/CXCR4 axis and reduced neuronal apoptosis in TBI rats. To conclude, our study demonstrated that the HIF-1α/SDF-1/CXCR4 axis could enhance BMSC migration and alleviate neuronal damage and apoptosis in TBI rats. This study provided novel options for TBI therapy. The kynurenine pathway (KP) has a principal role in the metabolism of tryptophan. This pathway is also involved in the pathogenesis of cancer. We evaluated expression of two rate limiting enzymes from this pathway (IDO1 and TDO2) as well as three long non-coding RNAs (lncRNAs) that have been predicted to alter expression of IDO1 (ITGB2-AS1, HCP5 and MIR155HG) in 82 breast cancer tissues and their adjacent non-cancerous tissues (ANCTs). While IDO1 expression levels were not significantly different between malignant tissues and ANCTs (expression ratio = 0.56, P = .21), TDO2 was significantly down-regulated in malignant tissues compared with ANCTs (Expression ratio = 0.001, P  less then  .001). Among lncRNAs, expression of HCP5 was significantly lower in malignant tissues compared with ANCTs (Expression ratio = 0.17, P  less then  .001). However, expression of ITGB2-AS1 was higher in malignant tissues compared with ANCTs (Expression ratio = 3.38, P = .01). Expressions of genes were not associated with any of clinical or demographic data of patients.
