Prekallikrein (PK) deficiency, also known as Fletcher factor deficiency, is a very rare disorder inherited as an autosomal recessive trait. It is usually identified incidentally in asymptomatic patients with a prolonged activated partial thromboplastin time (aPTT). In this article, we present the case of a 52-year-old woman, with no prior personal or family history of thrombotic or hemorrhagic disorders, who was noted to have substantial protracted aPTT through the routine coagulation assessment before a kidney biopsy. The patient had an uneventful biopsy course after receiving fresh frozen plasma (FFP). Laboratory investigations performed before the biopsy indicated normal activity for factors VIII, IX, XI, XII, and von Willebrand factor (vWF) as well as negative lupus anticoagulant (LA) screen. The plasma PK assay revealed low activity at 15% consistent with mild PK deficiency. The deficit of PK is characterized by a severely prolonged aPTT and normal prothrombin time (PT) in the absence of bleeding tendency. PK plays a role in the contact-activated coagulation pathway and the inflammatory response. Thus, other differential diagnoses of isolated prolonged aPTT include intrinsic pathway factor deficiencies and nonspecific inhibitors such as LA. We concluded that the initial evaluation of a prolonged aPTT with normal PT should appraise the measurement of contact activation factors and factor inhibitors. click here PK deficiency should be considered in asymptomatic patients with isolated aPTT prolongation, which corrects on incubation, with normal levels of the contact activation factors and factor inhibitors.

The biallelic inheritance of an expanded intronic pentamer (AAGGG)

in the gene encoding replication factor C subunit 1 (

) has been found to be a cause of cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS). This study describes clinical and genetic features of our patients with clinical suspicion of the syndrome.

A retrospective descriptive study from an ataxia database comprising 500 patients.

The study was performed at the Otorhinolaryngology Department of a hospital in the north of Spain.

Specific genetic testing for CANVAS was performed in 13 patients with clinical suspicion of complete or incomplete syndrome. The clinical diagnosis was supported by quantitative vestibular hypofunction, cerebellar atrophy, and abnormal sensory nerve conduction testing.

Nine of 13 (69%) patients met clinical diagnostic criteria for definite CANVAS disease. The first manifestation of the syndrome was lower limb dysesthesia in 8 of 13 patients and gait imbalance in 5 of 13. Eleven of 13 (85%) patients were carriers of the biallelic (AAGGG)

in

.

A genetic cause of CANVAS has recently been discovered. We propose genetic screening for biallelic expansions of the AAGGG pentamer of

in all patients with clinical suspicion of CANVAS, since accurate early diagnosis could improve the quality of life of these patients.

We propose genetic screening for biallelic expansions of the AAGGG pentamer of RFC1 in all patients with clinical suspicion of CANVAS, since accurate early diagnosis could improve the quality of life of these patients.This study placed the phenomenon of college women's fat talk within response styles theory. We predicted that with increasing trait body dissatisfaction there would be an increase in rumination leading to a greater frequency of fat talk. We also predicted that neuroticism would moderate this mediation pathway, and that these effects would occur over and above body size. A survey was conducted on a convenience sample of 212 college women with a mean age of 22.04 years (SDage = 2.61). A bootstrap analysis utilizing PROCESS software supported the predicted moderated-mediation model. Thus, those college women higher in both trait body dissatisfaction and neuroticism would experience greater rumination and engage more frequently in fat talk. Implications of applying a response styles perspective for future research and fat talk interventions are discussed.This study evaluates a hypothesized model describing the cognitive and emotional processes of childhood abuse and its influence on life satisfaction and explores the moderating effect of emotional expressivity in Korean young adults. The mediating roles of early maladaptive schema and state anxiety are explored, and the level of life satisfaction is compared according to the emotional expressivity level. A total of 550 young adults completed self-reported questionnaires, including Childhood Trauma Questionnaire (CTQ-SF), Young Schema Questionnaire (YSQ-SF), State-Trait Anxiety Inventory (STAI-Y), Satisfaction With Life Scale (SWLS), and Emotional Expressivity Scale (EES). The mediating roles of early maladaptive schema and state anxiety between childhood abuse and life satisfaction are confirmed. In the low emotional expressivity group, the double-mediation effect of early maladaptive schema and state anxiety is confirmed, whereas for the high emotional expressivity group, the mediating roles of each early maladaptive schema and state anxiety are confirmed, as well as the double-mediation effect. Moreover, the high emotional expressivity group showed higher life satisfaction. The study results imply that even though expressing emotions does not result in immediate mood elevation, but eventually leads to higher life satisfaction. The implications, limitations, and suggestions are discussed.This study aimed to investigate the levels of creatine (Cr) metabolites in the anterior cingulate cortex (ACC), thalamus, and insula of patients with fibromyalgia (FM) using proton magnetic resonance spectroscopy (MRS). The levels of Cr and phosphocreatine (PCr) relative to total Cr (tCr), which includes Cr and PCr, in the ACC, thalamus, and insula were determined using MRS in 12 patients with FM and in 13 healthy controls. link2 The FM group had lower levels of PCr/tCr in the ACC and right insula compared to healthy controls. There was a negative correlation between Cr/tCr in the ACC and total pain levels (McGill Pain Questionnaire-Total; r = -0.579, p = 0.049) and between Cr/tCr in the left insula and affective pain levels (McGill Pain Questionnaire-Affective; r = -0.638, p = 0.047) in patients with FM. In addition, there were negative correlations between stress levels (Stress Response Inventory) and Cr/tCr in the right (r = -0.780, p = 0.005) and left thalamus (r = -0.740, p = 0.006), as well as in the right insula (r = -0.631, p = 0.028) in patients with FM. There were negative correlations between symptom levels of post-traumatic stress disorder (PTSD; PTSD checklist) and Cr/tCr in the right (r = -0.783, p = 0.004) and left thalamus (r = -0.642, p = 0.024) of patients with FM. These findings are paramount to understanding the decisive pathologies related to brain energy metabolism in patients with FM.

Data in the Offspring Framingham Osteoporosis Study (FOS) suggested that higher intake of dietary fiber was modestly protective against loss of bone mineral density at the femoral neck in men but not in women.

To examine the relationship of fiber intake with risk of hip fractures in men.

We included 367 men from the FOS Original cohort, 1730 men from the FOS Offspring cohort, and 782 men from the Concord Health and Ageing in Men Project (CHAMP) in the analysis. Incident fractures were defined as medically confirmed first occurrence of osteoporotic fractures at the proximal femur. Fiber intake was estimated via a validated food frequency questionnaire (FFQ) or diet history. Cox proportional hazards models were applied to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). A random-effects model was used to estimate the pooled relative risk in meta-analysis.

Seventy-two incident hip fractures were identified, of which 24 occurred in the FOS Original cohort [mean (SD) age 75.3 (5.1) years; follow-up time 8.5 (6.2) years; dietary fiber 19 (8) (g/d)], 19 in the FOS Offspring cohort [58.8 (9.8) years; 11.0 (5.9) years; 19 (8) (g/d)], and 29 in CHAMP [81.4 (4.5) years; 5.2 (1.5) years; 28 (10) (g/d)]. We did not find significant associations within each cohort between fiber intake and risk of hip fractures. The pooled HR (95% CI) was 0.80 (0.39, 1.66) comparing energy-adjusted dietary fiber at tertile 3 vs. tertile 1 (I

= 0,

= 0.56).

These data suggested that dietary fiber was not associated with risk of incident hip fractures in men.

One of the requirements of concern is the adaptability of the mechanical properties of biomaterials to native tissues. However, the mechanical properties of current sealant are untunable or adjustable in a small range normally. Therefore, the scope of application of these sealant is limited. In this study, we developed hyperbranched polyester (HBP)-based UV-curable sealant with tunable mechanical properties. This sealant was cured under UV-light for 2 minutes and exhibited strong adhesion with tissues. The shear adhesive strength of it to the porcine skin ranged between 20-30 kPa, which was higher than the fibrin glue (∼10 kPa). Moreover, the elastic modulus of the sealant in a tensile test ranged between 27-54 MPa, depending on the degree of acrylation of the HBPs. Additionally, we assessed the biocompatibility of the sealant by co-culturing it with mouse mesenchymal stem cells (mMSCs) for 7 days and discovered that the cell viability was unaffected. This sealant with a tunable elastic modulus might be a promising candidate for treating wounds with different elastic moduli.The present research investigated whether message strength moderates the effect of self-affirmation on reactions given to cigarette warning labels. Three hundred eighty-four female (Study 1) and 383 male (Study 2) smokers completed a self-affirmation manipulation and then evaluated either strong or weak warning labels in terms of message derogation. Next, they reported their intentions to quit smoking. Only for the male sample, message strength moderated the effect of self-affirmation on message derogation. However, message strength did not have a moderating role on both message derogation and quit intentions for the female sample and on quit intentions for the male sample.Fatigue is common in all chronic inflammatory and autoimmune diseases. A conceptual model for understanding the biological basis of fatigue describes it as being a part of the sickness behaviour response generated by pro-inflammatory cytokines and other mediators. We hypothesised that the pro-inflammatory high mobility group box 1 (HMGB1) protein is a fatigue-inducing molecule and that auto-Abs against HMGB1 reduce fatigue. link3 We measured Abs against disulphide (ds) HMGB1 and fully reduced (fr) HMGB1 in plasma from 57 patients with Crohn's disease. Fatigue was rated using the fatigue visual analogue scale (fVAS) and disease activity with faecal calprotectin, C-reactive protein and the Simple Endoscopic Score for Crohn's disease. Multivariable regression models identified anti-dsHMGB1 and anti-frHMGB1 Abs as the strongest contributing factors for fVAS scores (B = -29.10 (P = 0.01), R2 = 0.17, and B = -17.77 (P = 0.01), R2 = 0.17, respectively). Results indicate that anti-HMGB1 auto-Abs alleviate fatigue possibly by down-regulating HMGB1-induced sickness behaviour.
